~ SNOW BOARD
~' .
The present invention relates to a snow board
with at least one mean~ for fa~tening one of the boots of
the snow board user on the base of th~ snow board.
Snow boards of thi~ generic type are already
known. The bindings of these known snow boards are fitted
firmly on the board base. In use of the snow board, the
user's foot supported at the rear on the board base
~ 10 assumes a position in which the longitudinal direction of
i the foot is virtually perpendicular to the longitudinal
direction of the ~now board. The longitudinal direction
of the foot located a the front of the snow board on the
other hand forms an acute angle with the longitudinal
direction of the snow board.
The ~ize of this angle is individual. The firmly
fitted bindings do not allow the individual differences
in the said angles to be taken into account.
The ob~ect of the present invention is to elim-
inate the said disadvantage~ and other disadvantage~ -
besides of the known snow boards.
According to the invention, this ob~ect is
achieved in the case of the snow board of the generic
type mentioned at the beginning, as i8 defined in the
characterizing part of claim 1.
l~ Exemplary embodiment~ of the present invention
are explained in more detail below with rHfsrence to the
attached drawings, in whicX:

The present snow board has a base 1, which i~
provided with at least one means 2 for ~nstening one of
the boots of the snow board u~er. Tho board normally
201054~
- 4 -
includeq two such mean~ 2, which are arranged at a
distance from each other. This di~tance is chosen such
that it is not found to be diRturbing by the user of the
snow board. However, since this distance depends, among
S other things, on the physical proportions of the snow
board u~er, at lea~t one of these means 2 may be designed
in such a way that the distance between the~e means 2 can
be altered. For this purpose, it is ~ufficient if at
least one of these two means 2 i~ mounted ad~ustably on
10the base 1. If the position of both fastening means 2 i8 :
adjustable, a further advantage is obtained, namely that
the position of tvhe user's center of gravity can be
changed and set optLmally with respect to the longi-
tudinal direction of the snow board.
15To the faqtening means 2 there belongs an anchor-
age plate 3 which, in the example shown, i8 worked into
~he base 1 of the snow board. This anchorage plate 3 may
also be fastened by means of suitable fastening means on
the surface of the board base 1. The plate 3, recessed
into the base 1 according to Figs. 1 and 2, i9 advan-
tageously unround, 80 that it cannot rotate in the
base 1. The anchorage plate 3 has an approximately
elliptical outer contour. In order to achieve an Lmproved
~; retention of the anchorage plate 3 in the base 1, it has
through-openings 42, into which the material of the
base 1 can penetrate during th~ production of the same.
In order to keep the weight of the ~now bo~rd a~ small as
pos~ible, the anchorage plate 3 may have varying thick-
ness. In the middle, where a pin S is connected to it,
the thickness of the plate 3 is at its greatest and this
thickness decreases in the direction of the plate edge.
The fastening mei~ns 2 further comprises a main
portion 10 and an ad~usting device 4, which is located
between the main portion 10 and the anchorage plate 3. To
the ad~usting device 4 belongs the pin 5, which i8
mounted approximately in the middle of the anchorage
plate 3. The pin 5 i8 surrounded by a le~d-through tube
6, which at one end i8 connected firmly to tho ~nchorage
pl~te 3. The outside of the casing of thi~ tube piece 6
: ' `
. ~ :
2010~4~
is surrounded by the material of the base 1, thi~
material advantageously adhering to the tube piece 6. In
~ha region of the upper -~ide of the base 1 there i8 a
disk 7 fastened on the lead-through tube 6, the edge
portion of which is provided with a toothed ring 8. This
toothed ring 8 i8 located on the upper side of the di~k
7 and has an internal toothing, ~o that this toothing i8
2ccessible from the top and from the in-~ide. The rim
portion of the disk 7 has furthermore radially extending
and downwardly sloping lug~ 9, which are worked into the
material of the base 1. These lugq 9, which are far a~ay
from the middle of the disk 7, represent a means which
i8 intended to prevent a rotational movement of the disk
7.
The fastening means 2 has the already mentioned
main portion 10, on which one of the boots 11 of the snow
board user can be located. Approximately in the middle of
the underside of the main portion 10 there is connected
to the underside of the main portion 10 an essentially
pot-shaped, low and hollow structure 12, which may also
be referred to as a flat bell. The inside diameter of
this bell 12 i~ cho~en such that the toothed ring 8 ~ust
fits into this bell 12. The middle region of the bell or
pot 12 i8 provided with a round opening, the diameter of
which is large enough for the upper end portion of the
tube piece 6 to fit into this opening. By means of this
opening and the upper end portion of the tube piece 6,
the bell 12, which i8 connected firmly to the base plats
10, is centered with respect to the toothed ring 8. In
the region of the middle opening in the bell 12, this
opening is ad~oined by a cavity 13 in the base plate 10~
in which the upper end of the pin S, protruding from the
board base 1, i8 located. The bottom of this cavity 13 is
provided with a flat bearing sleeve 14, in which the said
pin end is mounted.
A~ c~n be ~een in Fig~. 1 and 3, the main portion
10 i8 of elongats design, having a tapered region lS in
its middle. Tha bearing de~cribed above for the fastening
mean~ 2 i8 located in thi~ middle region 15. The wider
20~054~
- 6 -
end regions or end pieces 16 and 17 of the main
portion 10 are provided with means for the retention of
the tip and the heel of the boot 11. These mean~ are
designed as safety ski bindings.
In the heel region 16 there is an automatic heel
fitter 18~ the dimension of which in the longitudinal
direction of the base plate 10 is however to be as ~mall
as possible. This i~ because the width of the base 1 of
a snow board is comparable to the length of a ski boot
worn by an adult. A long automatic heel fitter 18 would,
under certain circumstances, protrude beyond the outline
of the ski board base 1. Automatic heel fitter~ 18 which
satisfy the said requirement are already known. These are
those automatic heel fitter~ which are mounted in the end
region of the heel and which act from above on the heel
section of the sole. Such an automatic heel fitter is
shown in Fig. 2. The yoke 19 of this automatic fitter 18
is pivotally mounted in the limbs of an approxLmately
U-shaped heel plate 20, the ~ross piece, ~oining the
limbs, of this plate 20 being located underneath the heel
in a depression 21 of the heel end piece 16. This depres-
sion 21 extend~ virtually over the entire length of the
heel region 16. In order to be able to ad~ust the auto-
matic fitter 18, the slide plate 20 may be provided with
laterally serrated ~trips, which mesh with correspond-
ingly laterally serrated strips in the heel end piece 16
of the main portion 10. With the aid of these serrated
strips, the position of the heel plate 20 can be ad~u~ted
in the longitudinal direction o~ the base plate 10.
The underside of the base plate 10 i8 proYided at
the end of the heel end piece 16 with a slide plate 22,
which iB of a slidable material, such as for example a
plastic, ~nd which i8 intended to prevent dzmage to th~
surface o~ the b~se 1 by the end edge of the ba~e plate
10 when the fastening means 2 rotates about the center of
the same.
The tip or toe end piece 17 of the main portion
10 i8, sim~larly to the heel end plece 16, designed with
a depression 21, in which laterally serrated strips (not

hown~ ara located. In this depre~sion 21 there is
mounted longitudinally displaceably and lockably an
automatically actuating hold-down device 24 for the sole
of the ski boot 11. Thi~ hold-down device 24 acts on the
801a in the region of the boot tip or of the boot front
part. The automatic boot front part fitter 24 must
likewise be as short as possible for the reafions already
explained. Since such automatic safety fitters 24 were
not yet available on the market, this first had to be
devised for the present case.
The sole hold-down device 24 (Fig. 2 and enlarged
in 18 and 19) has a sole plate 23, which is mounted in
the depression 21 of the toe end piece 17 of the main
portion 10. The underside of this sole plate 23 i~
provided with serrated strip~ (not shown), which mesh
with the serrated strips in the depression 21 of the toe
end piece 17. With ~he aid of these ~errated strips, the
position of the sole hold-down device 24 can be ~et in
the longitudinal direction of the main portion 10. At the
front end or edge of the 801e plate 23 there i8 fastened
a front plate 25, which pro~ects from the surface of the
sole plate 23 and i8 advantageously at right angles to
the latter. The end of the front plate 25 remote from the
sole plate 23 bears a housing 26, in which the mechanism
of the release for the sole edge holders or ~aws 27 of
the ~ole hold-down device 24 is accommodated. The housing
26 i8 designed in such a way that it extends rearwards
from the front plate 25 so that it lies at least parti-
ally above the boot tip. The front plate 25 is advan-
tageously made long enough for the underside of the
housing 26 not to touch the upper part of the shoe tip at
all.
The respective sole edge holder 27 i8 e88Qntially
arcuate in design, one of the end portions of thi~ holder
27 being fastened to a pivot pin 43. The other end
portion of this holder 27 i8 pivotal and it can be
brought into engagement with the sole 28 in the region of
the boot tip. ~he cross-~ectiQn, at lea~t of the pivotal
section of the holder- 27, i~ vlrtually L-shaped, thi~
2010544
-- 8 --
profile being turned through 180 degrees however. Thi~
means that the horizontal bar of this profile i~ at the
top and comes to rest from above on the sole edge. That
material section of the holder 27 which corresponds to
the vertical bar comes to rest on the ~ide face of the
sole 28. Between two such holders 27, the boot sole 28
can be retained in place not only in horizontal direction
but al80 in vertical direction. Of the ~aws 27 mentioned,
only the rear ~aw i8 represented in Figs. 2 and 18,
becau~e the section passes through the ~aw 27 at the
front.
The lower end of the pivot pin 43 ha~ a peg 44,
which is mounted in the sole plate 23. The upper end of
the pivot pin 43 is mounted in the housing 26. This upper
end of the pivot pin 43 i~ provided with means (not
~hown) which make it possible for this pin 43 to interact
with the mechanism of the automatic safety fitter. The
mechanism of the automatic safety fitter may be of a type
known per se.
On the sole plate 23 there is an antifriction
liner 29, which makes it possible for the boot front part
to slip easily out of the front automatic safety fitter
24 when the situation so requires.
Fig. 3 shows three of the pos~ible positions of
the fastening means 2 with respect to the longitudinal
direction of the board base 1. A~ can be seen, the
binding 2 can even be ~d~usted such that the longitudinal
axis of the ~ame runs virtually parallel to the longi-
tudinal axis of the base 1. This position of the binding
2 is indicated by,an uninterrupted line in Fig. 3. The
binding or fastening means 2 may be located in this
position whenever the user of the snow board i8 letting
himself be towed up a slope by a tow lift. The oblique
position, indlcate,d by dashed lines, of the bindlng 2
correspond~ approximately to that position which the foot
located at the front on the snow board normally ha3. The
position of the binding 2 drawn virtually perpendicular
to the longitudinal direction of the base 1 corresponds
approximately to the po8ition of the u~r's foot located
2010544
g
in the rear region of the base 1.
In order that the position of the fastening
means 2 can be altered with respect to the base 1 of the
snow board and then fixed, the ad~usting device 4 also
comprises a locking mechanism 30 (Fig. 4), whi~h i~
normally in engagement with the toothed ring 8 and i8
uncoupled from the toothed ring 8 for ad~ustment of the
position of the binding 2. This locXing mechanism 30 i~
arranged in the narrow region 15 of the main portion 10.
In this region there i~ formed a housing 31, the purpose
of which is to protect the interengaging parts of this
device against snow and dirt. The housing 31 has an outer
wall 32, which runs approxLmately vertically and in thi~
section represents ths side wall of the main portion 10.
The housing 31 has furthermore a top wall 33, which
extends from the outer housing wall 32 into the interior
of the bell 12, this top wall 33 being connected in a
waterproof manner to the base plate 10. Underneath the
top wall 33 i8 the mechanism.
In the upper region of the side wall 32 there is
an opening, through which an operating lever 35 of the
locking mechanism 30 passes. The outer arm 36 of this
lever 35 serves for tha actuation of the locking mechan-
ism 30 and it runs approximately perpendicular to the
longitudinal direction of the base plate 10. In the walls
bounding the opening there i8 mounted a spindle 37, which
pas~e~ through the lever 35, 80 that the latter can pivot
in the opening about it. The other arm 38 of the lever 35
i8 located in the interior of the housing 31 and has a
downwardly curved profile. The lower end of this second
arm 38 bears a toothed segment 39, the teeth of which are
directed towards the teeth of the ring 8 and can be in
engagement with them. With the aid of a spring 40,
pressinq again~t the lower end of the inner arm 38 and
having a flat cross-section, the toothed segment 39 is
kept in engagement w~th the toothed ring 8 whenever the
actuation arm 36 is not being operated. The spring 40
may, for example, be V-Qhaped, the one limb of such a
spring 40 being supported on the end of the inner arm 38

and the other limb of the same being supported on the
vertically running ~ection of the top wall 33.
Fig. 5 shows diagrammatically, and in a horizon-
tal section, a section taken from Fig. 4. In Fig. 5, the
outer arm 36 of the actuation lever 35 can be seen, which
is approxLmately at right angles to the longitudinal
direction of the main portion 10. It is also possible to
6ee the housing 31 of which the upper section has been
removed in order to obtain a view inside the same. In
this housing 31 there i~ shown a section from the toothed
ring 8 with internal teeth. In engagement with the
toothed ring 8 i8 the toothed segment 39, which is borne
by the inner arm 38 of the actuation lever 35. The
V-~haped spring 40, which lies in a plane running paral-
lel to the upper side of the board base 1, acts betweenthis arm 38 and the inside wall of the housing 33.
If the position of the fastening means 2 is to be
adjusted with respect to the base 1 of the snow board,
the operating arm 36 i8 pushed downwards, for example by
the other foot. As a result, the toothed segmen* 39
attached to the end of the inner arm 38 i~ brought out of
engagement with the toothed ring 8 fastened on the
base 1. The binding 2 i8 then free and it can be pivoted
85 desired about the pin 5. Once the desired position of
the binding 2 has been reached, the operating arm 36 is
released, the toothed segment 39 re-engages with the
toothed ring 8 and the po~ition ~ust set of the binding
2 is thereby fixed. It should be obvious that, with the
pre~ent snow board, the fastening means 2 can even be
ad~usted to such an extent that the board can be mounted
in one instance from the left and, after a pivoting of
the means 2 by about 180 degreeQ, then from the right.
The preQent snow board is equipped with a
brake 50 (Figs. 3 and 6), which acts automatically when
the fastening means 2 i3 relieved. This may be the case,
for example, if the user fall~, after which the ~afety
bindings 18 and 24 release. Th~ brake 50 ha~ a
spindle 51, which is rotatably mQunted on the upper side
of the board base l in bearing block~ 52 and 53 and which
2010~4~
11
runs essentially at right angles to the longitudinal axis
of the board base 1. The first bearing block 5~ i~
fastened close to the upper lateral edge 54 of the
base 1. The end of the pin 51 extending further behind
this bearing bloc~ 52 is bent off approximately at right
angles and acts as the actual braking element 55. During
braking, this braking element 55 is downwardly directad,
whereas in the unactuated state it lies almost parallel
to the surface of the ba~e 1. The second bearing block 53
is arranged close to the bell 12, which pro~ects
laterally beyond the main portion 10, as can be seen best
from Fig. 3. This second bearing block 53 is rece~sed a
little in the base plate 10. A part 56 of the end portion
of the pin 51 located in this region of the brake 50 i8
likewise bent off at right angles and this part 56 forms
a restoring lever of the brake 50. The restoring lever 56
and the braking element 55 lie virtually in the same
plane.
On the upper side of the main portion 10, a plate
57 is pivotally mounted with the aid of a pin 58. The pin
58 i8 fastened in the upper side of the main portion 10,
this fastening point 58 being located in the front region
17 of the fastening means 2. The plate 57 has an elongate
fastening section 59, which is ad~oined by a round plate
section 60. The diameter of this round plate section 60
is less than the diameter of the bell 12. Since the bell
12, which likewise pro~ects laterally from the base plate
10, is very low, there i8 a hollow space between the
upper side of this bell 12 and the underside of the
portion of the, round actuation plate 60 projecting
'lateraliy from the base plate 10. The restoring lever 56
lies in this hollow space. In the second bearing block
53 there is a spring (not shown), which act~ on the
spindle 51 in such a way that the braking element 55 i8
moved downwards and the restoring spring 56 is moved
upward~ when the actuation plate 57 is relieved. This
relieved state of the actuation plate 57 ~nd of the
re8toring 8prlng 56 i6 indicated by dashed lines in Fig.
6. The represent~tion indicated by unin~errupted lines on
' . ' ' ' , ' ,' ' ' : '
- 201054A
- 12 -
the other hand reproduces the plate 60 and the restoring
lever 56 in the loaded state, i.e. when the boot 11 i8 in
the binding 2. In thi~ loaded state, the braking element
55 also lies in a virtually horizontal po6ition.
As can be seen from Fig. 3, the upper side of the
ba~e 1 is provided with two stop~ 62 and 63. The first
~top 62 limits the pivoting movement of the front part 17
from the front to the rear in such a way that the binding
2 can, at most, assume a position perpendicular to the
longitudinal direction of the ba~e 1. The ~econd stop 63
limits the pivoting movement of the fastening means 2 in
such a way that the latter can, at most, transfer from
the transverse position mentioned into its longitudinal
position. If the means 2 move~ within the~e limits, the
restoring spring 56 is constantly underneath the actua-
tion plate 57. Consequen~ly, the brake 50 can be actuated
in each of the said positions of the binding 2.
In the case of the locking mechanism 30 according
to Fig. 5, the toothed ring 8 has teeth with 610ping
flanks. In order to achieve a greater safety in locking,
the toothed ring 8 may be designed such as i8 represented
in Fig. 9. ~he teeth 81 of this toothed ring 8 have
flanks 82 and 83 which run virtually parallel to each
other. The segment 39 in engagement with such a toothed
ring 8 has one or more teeth 84, the flanks of which
likewige run virtually parallel to each other. The
di~tance between the flanks of the segment tooth 84 is
less than the distance betwee~ the flanks 82 and 83 of
the gaps which exist between the teeth 81 of the toothed
ring 8. In order that the segment tooth 84 can enter more
easily into the reepective gap between the toothed ring
teeth 81, the toothed ring teeth 81 have bevels 85. The
segment tooth 84 may al80 be chamfered in this way. If
the teeth 81 and 84 are de~igned in this way, it iB
virtually impo~sible to bring them out of engagement
under the effect~ of a laterally acting force.
While traveling, the u3er of the snow board is
in a sidQways position with leg3 ~part. This position
require8 the underside of the boot 8010 28 to be at an
2010~44
- 13 -
an~le to the surface of the base 1. In the ca~e of the
pre~ent board, this can be achieved, for example
(Fig. 10), by a wedge 41 being arranged betwean the main
portion 10 and the respective part 18 or 24 of the
binding. The inclination of the wedge 41 run~ perpen-
dicularly to the longitudinal direction of the main
portion 10.
If necessary, such a wedge 41 may be fastened
interchan~eably in the binding.
While traveling, the user of the board perform~
movements which are nece~sary for the control of the
board. The wedges with fixed inclination prevent the user
from freely performing these movements. To remedy this,
the main portion 10 is designed in such a way that its
end portions 16 and 17 can swivel with respect to their
middle portion 15.
In the case of a first embodiment of the board,
solving this problem, the pin S has a cylindrical section
71 (Fig. 7), which i8 mounted rotatably in the lead-
through tube 6. This pin section 71 is made with alocking plate 72, which engages behind a peripheral
shoulder 77. This shoulder 77 is integrally formed on the
inside wall of the lead-through tube 6 and lies in a
peripheral groove, which is made in the outside wall of
this pin section 71. However, the mounting of the pin 5
- in the lead-through tube 6 can also be executed in
another way. The end of the pin 5 protruding from the
lead-through tube 6 i~ provided with a horizontal cross-
bar 73, whic~ is connected approximately in the middle of
its length to the cylindricnl pin section 71 and which
extends virtuallyi perpendicularly to th~ latter. The
cross-section of this crossbar 73 is advantageously
angular.
The elongate main portion 10 i8 msde, for ex-
ample, from a c~stable material, which in the hardenedstate allow~ a twisting of the middle, ~arrow region 15
of the main portion 10. If neces~ary, this material may
be reinforced with gla~æ fibers, carbon fibers or the
like. The cro~sb~r 7~ ~nd the section of the pin 5
2010~4~

protruding upwards out of the lead-through tube 6 is
cast-in in this material. As a re~ult, the main por-
tion 10 is mounted rotatably on the base 1, the middle,
narrow region 15 of this portion 10 no~ being able to
execute any movement~ about the longitudinal axL~ of this
main portion 10.
As already explained, broader end regions or end
pieces 16 and 17 ad~oin the middle region 15 of the
portion 10. The underside of these end pieces 16 and 17
has two walls 74 and 75 (Fig. 8) which are at an obtuse
angle to each other and are connected to each other by
means of a virtually round tran~itional wall 76 at their
lowennost point. This transitional wall 76 rests on the
upper side of the base 1 and can roll on the latter when
the end pieces 18 or 24 are swiveled.
If the user performs swiveling movements falling
in the direction of travel, the corresponding forces are
transferred via the automatic fitters 18 and 24 to the
main portion 10. Since the latter can be twisted, the end
pieces 16 and 17 of the same execute tor~aional movement~
with respect to the middle portion 15 of this main
portion 10. In order not to hinder the execution of these
movements, the underside of the end pieces 16 and 17 is,
as explained, V-shaped. These end regions 16 and 17 can
consequently execute swiveling movements, the magnitude
of which i8 dictated by the anS~le between the walls 74
and 75. During such movements, the rounded-off transi-
tional wall 76 rolls on the base 1. In order that the
middle, immovable region 15 of the plate 10 cannot hinder
the swiveling movements of the boot 11, it i8 expedient
to make the surface of this region 15 lower than the
surface of the end portions 16 and 17. The upper side of
the middle region 15 may, however, al80 be rounded off
for this purpose.
The main por~$on 10 of the fa8tening means 2,
which i8 represented in Fig. 11, function~ si~nilarly to
the main portion 10 represented in Fig. 7. ThiS is 80
~ince, in the ca8e of the main portion 10 according to
Fig. 11 as we~ll, the ~snd piece8 15 and 17 are ro~atable
201054~
- 15 -
with respect to the middle region 15 of the main
portion 10. According to Fig. 11, the main portion 10
contains torsion elaments 88, one of these torsion
elements 88 extending in each case between the respective
end piece 16 or 24 and the middle anchorage piece 5 of
the main portion 10 and connecting these piece~ of the
main portion 10 to each other. The torsion element~ 88
have a hollow and essentially cylindrical body 89, the
enda of which are terminated by sleeves 90 and 91. The
outside diame~er of the sleeves 90 and 91 may be equal to
the outside diameter of the body 89. The sleeves 90 and
91 are provided with a through opening 92, the diameter
of which is les~ than the inside diameter of the body 89.
The cross-section of the opening 92 in the sleeves 90 and
91 is advantageously angular~ in particular rectangular.
A vertical section through one of these sleeves 90 or 91
is reproduced in Fig. 14.
The anchorage piece 5 is virtually T-shape~, the
end of its vertical bar 71 being located in the base 1 of
the snow board. Here the vertical bar 71 may either be
fa~tened rigidly or mounted rotatably. At least the end
portions of the horizontal bar 73 on the anchorage
piece 5 are likewise of angular design in cross-section,
80 that one of the ~leeves 91 of the torsion element 88
can be fitted onto it. Since the opening 92 in the sleeve
91 is likewise angular, the torsion element 88 is ~eated
rotatably on the anchorage piece 5.
One of the end pieces 16 or 17 is associated with
the end of the torsion element 88 remote from the anchor-
age piece 5. The respective end piece 16 or 17 has a base
95, on which one of the binding parts 18 or 24 is
attached in a way already described. From one of the side
walls of this base 95 there pro~ects a profiled piece 94,
the outer cross-section of which corresponds to the inner
cross-section of the opening 92 in the sleeve 90. This
profiled piece 94 is fitted in the angular opening 92 of
the ~leove 90 and fastened there in a know~ w~y.
In Flgs. 12 and 13, two embodiments of the end
piece8 16 and 17 are ~hown in a re~rward view. The end
~, - . ~ : ....... - ,.. , . ......... ,:

piece with the base 95 according to Fig. 12 can be u~ed
with that fastening mean~ 2 which is located on the front
of the board base 1. The end piece with the ba~e gS
according to Fig. 13 may represent one of the compenent
S ~arts of the rear fastening means 2. The base~ 95
according to the two Figure~ 12 and 13 may be provided at
the top with one of the automatic fitter~ 18 and 24, as
described above. At the bottom, the respective base 9S
has the likewise already described bottom regions 74 and
75, which are at an angle gamma, other than 180 degrees,
with respect to each other. The inclination of these
bottom regions 74 and 75 runs perpendicularly to the
longitudinal direction of the main portion 10.
The first of the said regions 74 lies on the ~ide
of the base 95 facing the front part of the board base 1.
The second region 75 is on the side of the base 95 facing
the rearward part of the base 1. The angle alpha between
the first region 74 and the upper side of the base 1 is
relatively large, and it i~ between approximately 20 and
40 degrees. This i8 to allow the forward-directed move-
ment of the user to be performed as unhindered as pos-
sible. The angle beta batween the second region 75 and
the surface of the ba~e 1 is smaller and i8 between S and
25 degrees. This is because the user~ 8 backward inclina-
tion i8 normally less great.
In the case of the base 95 (Fig. 12) of the end
pieces 16 and 17 for the front fastening means 2, the
surface or the depression 2I in the end piece lies
virtually parallel to the upper side of the ba~e 1. In
the case of the base 95 of the end pieces 16 and 17 for
the rear fastening means 2, the surface of the base 95 i8
oblique with respect to the upper side of the ba~e 1. In
this case, the bottom of the depression 21 is inclined
forwards in order that the user's foot can already as~ume
in the position of rest the natural attitude obliquely
forwards. This initial inclination of the base 95 is
achieved most ea~ily by the profiled piece 94 being
att w hed to the baso 95 in a turned position with respect
to lt. In the case of thi~ base 95 for the r~ar fa#tening
2010~4~
- 17 -
mean~ 2, the region~ 74 and 75 may be arranged
un~ymmetrically with respect to the vertical center plane
of the base 93. The angle between the second region 75
and the sida wall 96 of the base 94 may be a right angle,
as is represented in Fig. 13, so that the angle beta i8
smaller than the angle alpha.
If the crossbar 73 of the anchorage piece 5 i~ to
be rotatable, it may be fitted on the middle bar 71, it
being able to support itself on an extension 94 on the
middle bar 71 (Fig. 11).
The torsion in the case of the main portion 10
can also be achieved by the latter only having a single
torsion element 88 which extends between the end piece~
16 and 17. This embodiment i8 represented in Figs. 15 to
17. In Fig. 15 only one half of such a main portion 10 i8
represented, because the other half of the same is of an
identical design. This main portion 10 has a rigid
pin 100, the profile of whi~h is angular, advantageou~ly
rectangular, and the ends of which are fastened in
bearin~ blocks 101. These bearing blocks 101 are fastened
on the ba~e 1 with the aid of screws 102 (Fig. 16) and
are located in the region of the respectivs end piece 16
or 17. The torsion element 88 is tubular. In the middle
region of the same, the hollow space 92 in this
element 88 has a diameter over a certain length 103 less
than otherwise and, apart from this, the shape of the
cross-section in this hollow space 92 i8 the same as the
cross-section of the pin 100. The diameter of the
portions of the element 88 lying outside this middle
region 103 is greater than the diameter of the pin 100,
with the result that these portions of the element 88 can
be rotated with respect to the pin 100. The end pieces 16
and 17 are fastened unrotatably to these portion~ of the
torsiGn element 88. The rearward section of the end
pieces 16 and 17 has a niche 104, in which the bearing
block 101 is located, in order that the fastening means
2 is a~ short a8 possible. The end pieces 16 and 17 may
be e8sentlally of the s~me de~ign as repre~ented in Figs.
12 and 13. The only difference is th~t the end pieces of

this embodiment do not have any profiled pieces 94 on the
base but are provided with through-holes 105, through
which the pin 100 passes with clearance.
By means of the pivoting mechanism de~cribed, the
setting angle between th~ boot and the board base can be
altered quickly as well as as often as desired and as
much as de6ired. This doe3 not involve the ~now board
bas~3 being damaged and weakened by the drilling of
further holes for new ~ettings of the binding as was
previously the case. The binding can be set according to
the individual learning phases of the user and to the
re pective conditions of the snow and terrain. On a tow
lift, the front binding can be set without any problems
parallel to the direction of travel, which makes a
comfortable transportation by mean~ of the tow lift ~`
possible. The distance of the bindings can ~e altered for
different body sizes of the board users. Not only bind-
ings which release automatically when overloaded but al~o
those which simply usa straps or the like can be used on
the binding base plate.
As can be seen from Fig. 20, ~he main portion 10
may be designed as an elongate body with an es~entially
rectangular cross-section. Its middle region 15 is
connected to the ad~usting device 4. The end regions 16
and 17 of the main portion 10 are provided with means 18
and 24 for retaining the heel and the tip of a boot,
advantageously of a usual ski boot. The respective
retaining means 18 and 24 is attached to a slide plate 20
and 23, respectively, which is displsceable along the
main portion 10. These slide plates 20 and 23 are virtu-
ally U-shaped in cross-section. The limbs 114 (Fig. 21)
of the respective slide plate 20 and 23 are relatively
short. The length of the plate-6haped cross piece 115
connecting the limbs 114 is somewhat greater than the
width of the main portion 10, with the re~ult that the
limbs 114 of the respective slide plate 20 and 23 can
rest again~t the ~ide faces of the main portion 10. The
free end portions 115 of the limb8 114 are bent inwards
and they 9ngage behind the l~teral edges o~ the main
,
2010544
-- 19 --
portion 10. Ae a result, the guidance of tho slide plates
20 and 23 along the main portion 10 i8 ensured.
In order that the slide plates 20 and 23 can be
moved along the main portion 10 eaæily and without any
S clearance, there i~ an antifriction liner 29 in each case
between the upper side of the main portion 10 and the
cros3 piece 115 of the respective slide plate 20 and 23.
These antifriction liner~ 29 are advantageously of a
plastic and the length of the same is greater than the
length of the cross piece 115 in the longitudinal direc-
tion of the main portion 10. Consequently, a spur of the
liners 29 extend~ towards the middle 15 of the main
portion 10. The ad~uxtment of the position of the slide
plates 20 and 23 along the main portion 10 can be per-
formed, for example, with the aid of spindles 117 known
per se (Fig. 21), which are mounted in the main portion
10 and the threaded portions of which are in engagement
with nuts (not shown), fa~tened to the slide plates 20
and 23.
In the heel region of the main portion 10 there
is a yoke or bow 19, which can act from above on the heel
section of the boot sole. The yoke 19 is made as a piece
of stiff wire, advantageously of spring st~el, which is
essentially U-shaped. The end portions 118 of the
limbs 111 and 112 of such a yoke 19 are bent inwards and
they are mounted pivotally in the limbs 114 of the heel
slide plate 20. The yoke 19 is angled off approximately
in the middle of the length of the limbs 111 and 112
transversely to the longitudinal direction of the latter,
with the result that the respective bow limb 111 or 112
has a first section whlch ad~oins the inwàrdly bent end
portions 118 and slopes upward when the bow 19 rest6 on
the upper side of the heel section of the boot sole. This
sloping section i~ then ad~oined by a virtually
horizontally running section of the limb 111 and 112 (not
shown)~ these horizontal limb sections resting on the
upper edge of the boot sole. Between the latter there
extend~ ~n arcuate cross piece 113, which interconnects
th~ end~ of the limb8 111 and 112 re~ote from the heel
2010~4~
- 20 -
plate 20.
The retaining means 24 in the boot tip region
have an essentially V-sh~ped bow 120, the limb8 121 and
122 of which likewige have inwardly bent end portions
118. These end portions 118 are mounted piYot~lly in the
boot tip slide plate 23, this mounting being of virtually
the æame design as in the case of the bow 19 of the heel
retaining mean~ 18. The respective limb 121 and 122 of
the bow 120 has an outwardly bent shape, in order *hat
the bow 120 can be brought over the angular sole in the
boot tip region. The cross piece 123, which connects the
other end portions of the limbs 121 and 122, runs in a
straight line in the case of this bow 24 and on this
cross piece 123 there i~ pivotally mounted a holder 125
for the sole in the boot tip region.
The holder 125 has an essentially plate-shaped
main body 126, in which a hole 127 with essentially
smooth inside walls is made. This hole 127 runs parallel
to the ma~or surfaces of the main body 126 and the axis
of this hole 127 is virtually perpendicular to the
narrower side faces 128 of the main body 126. The section
130 of the main body 126 above this longitudinal hole 127
serves as an actuation lever for the holder 125 and it is
provided with recesses or pro~ections 131, which are
intended to facilitate the ~rasping of this lever 130.
The ~ection 132 of the holder 125 underneath the longi-
tudinal hole 12~ serves as an acting lever, which act~ on
the upper side of that section of the boot sole which is
located in front of the boot upper part in the region of
tho boot tip. The msin body 126 is widened in the region
of the front edge 133 of the acting l~ver 132 and the
front edge 133 itself forms a concave bow. The front side
of the upper part in the region of the boot tip i8
normally convexly round and this round portion comes to
rest in the arcuate front edge 133 of the holder 125 when
this binding part 24 i~ clo8ed. The front edge 133 shaped
in this way prevent~ the boot tip shifting to the left
and right in the binding 24 during travel, which would
imp~lr the guidance of the board.

In the main body 126 of the holder 125 there i8
also a threaded hole, in which a setscrew 134 is screwed.
The axis of this threaded hole runs almost perpendicular
to the m~in face of the holder 125. The screw 134 has the
form of a grub screw, the tip of this grub screw 124
being directed towards the heel portion 18 of the binding
and thus also towards the boot tip. The tip of the
setscrew 134 may rest on the front side o~ the boot upper
part when the binding is closed. The setscrew 134 can be
used to set the path which the holder 125 can cover when
the binding i8 closed.
To the fastening means 2 (Fig. 20) belongs an
anchorage plate 3 (Figs. 22 and 221), which in the
example represented is fastened on the upper æide of the
base 1 of the snow boardO Resting on this anchorage
plate 3, the upper side of which is essentially flat,
with the exception of its edge portion, i8 a rotor 135
(Fig. 23), which has essentially the form of a flat ring.
on the rotor 135 there rests an intermediate disk 136
(Figs. 26 and 27) which is designed approximately in the
form of a dish, the outer rim of which rests on the upper
inner edge of the rotor 135 (Fig. 27) and which is
advantageously of a plastic. This intermediate disk 136 ~-
is covered by a retaining disk 137 (Pigs. 24 and 25),
which i~ likewise of a rigid material. Connecting means,
for example rivets, are provided (not shown), the heads
of which rest on the upper side of the retaining
disk 137, the bolts of which pass through opening~ in th~
retaining disk 137 and in the intermediate disk 136,
through the inner opening in the annular rotor 125 and
through openings il42 in the anchorage plate 3, the
sections of the bolt~ pro~ecting from the underside of
the anchorage plate 3 being formed into heads. The said
component parts thus form a whole, which can be fastened ~ -~
on the board base 1 via the anchorage plate 3.
The anchorage plate 3 is represented in Fig~. 22
and 221. In Fig. 22, this plate 3 is shown in plan view
and in Fig. 221 it is sh~wn in a vertical section I-I. It
has a main body 140, which ha~ tho form of an esssntidlly
: ' : .-: . . ~ :
2010~4~
_ 22 -
flat ring. The outer rim portion of thi~ rlng 140 i~
ad~oined by spurs 143, 146, 148 and 149. In the vicinity
of the central opening 141 in the annular main body 140
there are holes 142 for the connect-ng means already
mentioned. The arrow L in Fig. 22 shows approximately the
longitudinal direction of the board base 1, this arrow
also indicating the position of the tip of the board
base 1.
The narrowest of all the spurs 143 on the anchor-
age plate 3 i8 provided simply with an opening 144,
through which one of the screws 145 (Fig. 20) usPd to
fasten the anchorage plate 3 on the board base 1 passes.
This fastening screw 145 has a countersunk head and the
fastening opening 144 i8 desi~ned for receiving such a
countersunk screw 145 (Fig. 221).
Approximately diametral to the narrowest ~pur 143
there is a further spur 146, which is somewhat broader
than the first spur 143 and which likewise has a fasten-
ing opening 144. However, apart from this fastening
opening 144, in this spur 146 there is also a further
opening 147, which i~ intended for receiving a pin of the
ad~usting device 4. The design of this ad~usting device 4
i8 described in more detail below. The position of the
moderately broad spur 146 is chosen in relation to the
longitudinai direction L of the base 1 such that the
longitudinal axis of the main portion 10, which is
mounted on this anchorage plate 3 rotatably and lockably
with respect to the main portion 1, coincides with the
longitudinal axis of the board base 1.
To the left and right of the moderately broad
spur 146 there is in each case a further, but relatively
broad spur 148 and 149. These spurs 148 and 149 are
essentially of the same design. With regard to the
position of these spurs 148 and 149, it may also be ~aid
that the respective broad spur 148 or 14 is located on
the outer rim of the ring 140 between the narrowest spur
143 and the moderately broad spur 14~.
Ea~h of the broad or broade8t spurs 148 ~nd 149
ha8 one of th~ fa~toninq oponing~ 144 and, in addition,
~- . , - .:. : , :
. . - , . -: : ; ,:
2~10~4~
- 23 -
it is also provided with a number of the catch openings
147 already mentioned. In ths case of the raspective spur
148 or 149, the catch openings 144 form a row, the shape
of which i~ curved. Such a row of catch openings 147
S extends along a circular segment. The center of this
circular segment coincide~ with the center of the central
opening 141 in the anchorage plate 3. That section of the
respective broad spur 148 or 149 in which the catch
openings 147 are made is toward the moderately broad spur
146, in which that catch opening 147 which fixes the
longitudinal position of the main portion 10 is made. The
fastening opening 144 in the respective broad spur 148
and 149 only follows on after this row of catch openings
147. This fastening opening 144 i8 consequently made in
that section of the broad spur 148 and 149 which i8
toward the narrowest spur 143.
The main portion 10 of the fastening means 2 can
be pivoted out of its longitudinal position either to the
left or to the right, with the result that it is oblique
to the longitudinal direction L of the board b~ae 1. When
pivoting to the right, the means 24 for retaining the
boot tip are close to the right-hand edge of the board
base 1. When pivoting to the left, the boot tip i8 close
to the left-hand board edge. In thi~ pivoting, the pin
already mentioned of the ad~usting or locking device 4
can be brought into engagement with one of the catch
openings 147 in the respective broad spur 148 or 149. As
a result, the set po~ition of the main portion 10 is
fixed until it is disengaged by a renewed actuation of
the locking device 4 and altered a~ desired. The broad
~purs 148 and 149 thus make it possible to set the main
portion 10 obliquely to the board ba~e 1, to be precise
in such a way that the oblique position of the main
portion 10 in relation to the base 1 appears to be at an
optimum to the user of the board. The angular distance
between th~ neighboring catch openin~s 147 of one of the
raws cf openings i8 advantageously 7 degrees, which
8hould mak0 an adequat~ly fine setting possible of the
fa~tening mean~ 2 with r~pect to the board bsse 1.

On the underside of the anchorage plate 3 there
are material accumulations 150 (Fig. 221), which surround
the lower mouths of the openings 142, 144 and 147 and
thereby extend them downwards. ~he opening mouth~ ex-
S tended in this way lie virtually in the same plane. The
lower mouth of the openings 142, through which the
connecting mean~ for the anchorage plate 3, the rotor
135, the intermediate disk 136 and the retaining disk 137
pass, is provided with a widening 163, which is intended
fer receivinq the terminating head of the connecting
means, for example of a rivet. In the region of the upper
mouth of the catch opening or catch openings 147 there
are material accumulations lS1. One of these material
accumulations 151 is also associated with the catch
opening 147 in the moderately broad spur 146. On the
broad spurs 148 and 149, the upper material accumulations
lSl associated with the individual catch openings 147
form continuous segments 152. One of these segments 152
i8 represented in Fig. 221 on the right in a side view.
The underside of the main body 140 iq provided
with planar recesses 153, from the bottom of which the
lower rnaterial accumulations 150 and reinforcing ribs 15~
rise up (Fig. 221). The reinforcing ribs 154 also extend
along the edge of the anchorage plate 3.
On the anchorage plate 3 there lies the rotor
135, which likewise has the form of a flat ring and is
represented in 2 plan view in Fig. 23. The ring 135
comprises two almost semi-annular segments 156 and 157,
the end portions of which are connected to each other by
means of a cross piece 158 on each side. On the upper
side of the end~portions of the respective rlng segment
156 and 157 there is fastened a low ring 155, which i8
intended for receiving one of the ends of a spring, still
to be described. Each cross piece 158 has straight side
edge~, which extend between the end~ of the ring ~egment~
156 and 157. A lug 159, which is virtually at right
angle~ to ths plane of the cross piece 158, rise~ up in
tho reqion of tho ro~pective cro88 pisce ~ide edge. In
Fig~ 231, that part of th~ rotor 135 which is on the left
- 20~0544
- 25 -
in Fig. 23 is represented. Each cross piace 158 con-
sequently has two upwardly ~utting lugs lS9~ In each lug
159 ~here is a through-opening 160, to be precise in such
a way that the openings 160 in all four lugs 159 of the
rotor 135 align with one another.
The outer rim portion of one of the ring 8egment8
156 is provided with a ~pur 161 (Figs. 23 and 231), which
is designed for receiving a locking mechanism 162 (Fig.
232). This locking mechanism 162 comprises the already
mentioned catch pin 164, which can be brought into
engagement with one of the catch openings 147 in the
anchorage plate 3. The spur 161 is designed as a material
strip, which is connected at one end to the ring ~egment
156 and which is bent such that it has an approximately
U-shaped form. The U-shaped spur 161 rests on one of its
limbs 181, the free end of this limb 181 being connected
to the ring segment 156. The other limb 182 of the
U-shaped spur 161 likewisa runs horizontally and i8
located at a distance from the first, lower limb 181.
Nade in the limbs 181 and $82 there are mutually aligned
openings 183, through which the catch pin 164 pas~es.
The catch pin 164 has a lower portion 184 and an
upper portion 185, the diameter of the upper pin portion
185 being smaller than the diameter of the lower pin
portion 184. The diameter of the opening 183 in the lower
- limb 181 i~ correspondingly largsr than the diameter of
the opening 183 in the upper limb 182. The upper edge
portion of the lower pin section 184 is located in that
free space which is bounded above and below by the limb8
181 and 182. That part of the thinner section 185 of the
catch pin 164 which i8 located between the limb~ 181 and
182 is surrounded by a compression spring 186. The lower
end of this helical spring 186 rests on the upper edge of
the thicker section 184 of the pin 164. The upper end of
the compression spring 186 rests on the underside of the
upper limb 182. In the unactuated state, this spring 186
force~ the catch pin 164 to remain in its lower position,
repre8ented in Fig. 232.
The upper end of the ca~ch pin 164 lies above the

upper spur limb 182 and is mounted pivotally in a lever
190, lying on the upper side of the upper ~pur limb 182.
For this purpose, ~he lever 190 has a recess 191, which
is located approximately in the middle of the same and
which opens downwards. In this recess 191 lies the upper
end of the catch pin 164, and a peg 192, by means of
which the catch pin 164 is connected to the lever 190,
passes through this pin end as well as through the wall
sections of the lever recess 191 on either xide of the
said pin end.
The lever 190 acts as a one-armed lever. The end
portion of the lever section 193 represented on the right
i rounded off and it rests on the upper spur limb 182.
The section 194 of the lever 190 represented on the left
is designed l~ng enough for its end portion to project
laterally from the spur 161. If this lever section 194 i3
lifted manually, the lower pin portion 184 leave~ the
catch opening 147 in the anchorage plate 3 and the rotor
135 can be swiveled about its center.
The spur 161 for receiving the locking mechanism
162 is arranged on the circumference of the rotor 135 in
such a way that the longitudinal axis of the main portion
10 run~ parallel to the longitudinal axis of the board
base 1 when the catch pin 164 is in engagement in the
catch opening 147 of the moderately broad spur 146 on the
anchorage plate 3.
The position of the rotor 135 on the anchorage
plate 3 is not determined -by the form of the anchorage
plate 3, because the contact surfaces of these component
parts 3 and 135 are essentially flat. ~he position, and
thu~ also the center of rotation, of the rotor 135 in
relation to the anchorage plate 3 are determined with the
aid of the already mentioned retaining plate 137 (Fig~.
24 and 25). The main body 165 of the retaining plate 137
is designed as a rigid di6k, the rim portion of which has
a ~tep-shaped peripheral offset 166. The offset rim
portlon 166 lies higher than the remaining part 167 of
th~ disk main body 165. Th~ und0rside of th~ rim portion
166 thu8 has a periph~ral And cross-8ectiQnally ~tep-
. ,, ..;

shaped free ~pace, which i8 bounded at the top by the
underside 168 of the offset rim portion 166 and at the
side by the inner flank 169 of the offset. The offset 166
is designed such that the diameter of the inner flank 169
is somewhat less than ths in~ide diameter of the annular
rotor 135, with the result that the upper inner edge of
the rotor 135 can be accommodated in the free ~pace
bounded as inside wall by the offset 166.
In the middle part 167 of the retaining disk 137
there are four openings 142 for the passage of the
already discussed connecting means of this rotary mech-
anism. These opening~ 142 are arranged such that they can
be aligned with the corresponding openings 142 in the
anchorage plate 3 when the retaining disk 137 lie~ on the
anchorage plate 3. In the undsrside of the retaining di6k
137 there ~re four approxLmately bo3s-shaped pro~ec-
tions 170.
In order that the friction between the retaining
disk 137 and the anchorage plate 3 lying underneath it i~
as small as possible, in between there i8 the likewise
already mentioned intermediate disk 136 (Figs. 26 and 27)
of a suitable plastic. This intermediate disk 136 like-
wi~e has a rim portion 171 which i8 raised and designed
in the form of a step and which lies between the upper
inner edge of the rotor 135 and the offset rim portion
166 of the retaining disk 137. The remaining part, i.e.
the inner part 172 of the intermediate disk 136, has
openinqs 172, through which the connecting means can pas~
with clearance. In addition, the inner part 172 of the
thin intermediate disk 136 has openings 173, the position
of which corresponds to the position of the boss-shaped
pro~ections 170 on the retaining disk 137. When the three
parts 137, 136, 135 and 3 lie one on top of tha other,
the approximately half-round boss-shaped pro~ections 170
pass through the smaller openings 173 in the intermediate
disk 136 and rest on the upper ~ide of the anchora~e
plate 3. These pro~ections 170 prevent the intermediate
di8k 136, whlch 16 of a eoft materi~l, be~n~ squeezed
b~ttweon. th~ retaining di~ 137 and the rotor 135 when the

connecting means are tightened.
As already said, the main portion 10 of the
fast~ning mean~ 2 i8 essentially rectangular in plan viaw
(Fig. 28). It has a base plate 175, which i~ essentially
rectangular and elongate and the cross-section of which
has the form of a very widely opened V. The cross-section
of this base plats 175 can be seen well, for example,
from Figs. 21 and 31. Figs. 29 and 30 show the ba~e plate
175 in a side view, with the result that the longitudinal
kink in the middle of the base plate 175 can likewi~e be
seen from these Figures. The line of the kink 166, which
is located at the lowest point of the V-shaped cros~-
section, run~ in the longitudinal direction of the base
plate 175 and is located virtually in the middle of the
width of this plate 175. Bulges 177 are forced through in
the base plate 175 and serve as reinforcing ribs of this
plate 175.
From the underside of the base plate 175 there
project lugs 178 with openings 179 (Figs. 28 and 29),
which are of virtually the same design as the lugs 159 on
the rotor 135. In the assembled state, the lugs 178 on
the base plate 175 are associated with the lugs 159 on
the rotor 135 in such a way that the openings 160 and 179
in the latter are aligned with one another. A pin 180
(Figs. 21 and 231) passes through these openings 160 and
179 and the main portion 10 is connected to the rotor 135
with the aid of this pin 1800 The main portion 10 can be
swiveled about the axis of the pin 180 with re~pect to
the rotor 135 within certain lLmits.
As can be seen in particular from Fig. 28, the
plate 175 of the main portion 10 has several pairs of
openings. The middle pair of openings 195 and 196 is
designed for receiving limiting scrQws 197 (Fig. 31). In
the region of the respective opening 195 and 196, bushes
198 which have an internal thread, are fitted in the ba~e
plate 175. The limiting screws 197 are designed as grub
screw8, which are screwed into the bushe~ 198. The upper
end portion of the grub 8craw 197 i~ provided with A ~lot
for th0 in~ertion o a screwdrlv6r, 80 that they can be

ad~usted from above. The bottom end faces of the ~crews
197 rest on a pro~ecting and peripheral bulge 199, which
is made in the upper side of the retaining plate 137. The
more the grub screws 197 protrude from th~ base plate
175, the smaller the swiveling range of the main portion
10 about the pin 180. The æwiveling range of the main
portion 10 can be set with the aid of the screws 197.
When the grub screws 197 are not fully extended, -~
the base plate 175 could swivel freely about the pin 180
and it could assume any position in relation to the board
base 1. This would be of disadvantage in particular when
getting into the binding. In order to give the main
portion 10 a defined initial po~ition, zero-po~ition
dampers 200 (Figs. 2B and 32) are provided. The
re~pective damper 200 is made as a strip of a compliant
plastic, which has an approximately rectangular cro~s-
section. The strip 201 is bent in the middle of it~
length, with the result that it likewise has the form of
a widely opened V. In its middle region, the underside
202 of the strip 201 is flattened off, with the result
that here there is a flat and virtually horizontally
running supporting surface 203. A bush 205 with internal
thread is recessed into the respective arm of the
V-shapsd damper 200 from the upper side 204.
To the left and right of the middle opening pair
195 and 196 in the base plate 175 ther~ are further
opening pairs 206 and 207. The distance between the
bushe~ 205 on the damper 200 is equal to the distance
between the opening3 206 and 207 of these further pairs.
Screws (not shown? are passQd through the openings 206
and 207 and screwed into the bushes 205. In this way, two
dampers 200 are fastened on the underside of the base
plate 175. The height of the dampsr strips 201 is chosen
such that the fitted damper 200 rests with its base area
203 on the upper side of the retaining di~k 137. Since
the supporting surface 203 runs horizontally, the zero
position of the main portion 10 i~ virtually in a hori-
zontal plane. ~ ;~

this could not retain the main portion 10 in the desired
position while traveling. For thi~ purpose, spring~ 210,
in particular helical springs, are provided, which are
fastened on the underside of the base plate 175 ~Figs. 21
and 28). For the fastening of the springs 210, in the
base plate 175 there are opening pairs 211 and 212, the
underside of whi~h is rainforced with a material accumu;
lation 213. Ona end of the respective spring 210 iB
fastened to this material accumulation 213, for example
with the aid of a screw. The other end of the ~pring 210
rests inside the ring 15S, which i8 fastened on the upper
~ide of the rotor 135.
Fig. 30 shows the base plate 175 in a side view,
the front section of the base plate being removed in the
middle region of the ~ame in order to be able to show the
retaining and guiding mean~ for the ~pindle 117. The
spindle 117 i8 indicated in Fig. 30 by a dot-dashed line.
For the guidance and retention of the ~pindle 117 in the
middle region 15 of the base plate 175, lugs 214 are
provided, which ~ut upwards from the bot~om 176 of the
base plate 175 and are made with incisions, openings or
the like, in which the correspondingly grooved portions
of the spindle 21 are mounted. The end~ of the spindle
117 lying in the end region 16 or 17 of the main portion
10 are in engagement with the binding parts 18 and 24
and, as a result, they are guided in these regions 16 and
17 of the main portion 10.
On the elongate main body 10 thera is a first
pair of springs 210 in the region of the boot tip and a
further pair in the region of the boot heel ~Fig. 33). It
may be wished for the base plate 10 to be able to tilt
not only about the pin 180 but also in another direction,
which is perpendicular to the axis of the pin 180. This
wish can be accommodated by making the opening 160 in the
rotor lugs lS9 or/and the opening 179 in the ba~e plate
lugs 170 not a8 round holes but a8 slots. In the cnse of
the ex~mple represented in Fig. 33, the opening 160 in
- the rotor lug~ 159 is made ~s a 8}0t. If the pressure on
the ba~e plate 10 ~com~s gre~t~r in the region of the

boot tip than in the region of the heel, for example, the
springs 210 in the boot tip region are compressed more
than the rear spring pair 210 and the pin 180 move3
downwards accordingly in the slot 160 of the front rotor
S lugs 159.
In addition, the slot~ 160 and 179 in the lugs
159 and 178, respectively, make a type of spring of the
boot bindings with respect ~o the base of the snow board
possible, which make~ use of the snow board more
pleasant, for example when performing ~umps with the snow
board.
In order that the base plate 10 can also be
lowered unhindered in each of its inclined positions, the
lugs 159 and 178 are designed such that the free end
portions 215 and 216 of the same are rounded off. In
addition, the end of the slot 160 or 179 facin~ the
respective edge 215 or 216 should be a3 close as po~sible
to this edge.
Instead of the lugs 159, 178 and the shaft 180
described above, blocks 220 of a tough but compliant
material are used for the connection of the base plate
10 to the base 1 of the snow board (Figs. 34 and 35).
These blocks 220 may, for example, be of a suitable
plastic. It is expedient if one block 220 is arranged in
the region of the boot tip and a further block 220 is
arranged in the region of the boot heel, 80 that the
middle region of the elongate base plate 10 remains free
and can be used for other ~urposes.
The respective block 220 may be of an elastomer
and it may advantageously have a round cro~s-section
(Fig. 34). Such a~ blocK 220 is arranged such that its
outer sur~aces 221 and 222 are associated with the parts
10 and 135 to be connected to each other. In the present
example, the lower base area 221 of the block 220 is
a~sociated with the rotor 135. Since the upper side of
the rotor 135 is es~entially flat, the lower main area
221 of the block 220 cAn likawise be flat. A threaded
bush 223 is rece8sed into the lower ba8e area 221 of ths
block 220. If the block 22Q has a round cross-~ection,
, ' ~
2010~4~
,
- 32 -
the threaded bush 223 can be located in the middle of the
baæe area 221. The block 220 may, however, al80 be of
elon~ate design. In this case, the longitudinal latter
expediently coincides with the longitudinal direction
of the latter expediently coincides with the lon~itudinal
direction of the base plate 10. To make the connection
between ~he base plate 10 and the base 1 of the ~now
board more ~ecure, a plurality of threaded bushes 223 may
be recessed into the block 220 in one or more rows. It
qoes without saying that the elongate block 220 may also
be arranged virtually perpendicular to the longitudinal
direction of the base plate 10 (not shown).
A fastening screw 225 is provided, the bolt 226
of which can be screwed into the threaded bush 223. The
head 227 of this screw 225 i8 to have as large an area as
pos6ible. In the rotor 135 or in another plate 135, even
not pivotally fastened on the base 1 of the snow board,
there is a through-opening, through which the bolt 226 of
the screw 225 is inserted when the said bolt is to be
screwed into the threaded bush 223. The plate 135 is
clamped and retained between the head 227 of the screw
225 and the base area 221 of the block 220. Such plates
135 are usually of sheet metal and, in order that ~hey
do not become deformed in the area around the bolt
opening, the screw head 227 is to have a large area.
Since the base plate 10 has a V-shaped cross-
section, the upper base area 222 of the block 220 has a
correspondingly ~haped depression. It goes without saying
that the form of the contact surfaces on the block 220
can be designed according to the form of the respective
ob~ect to be connected to this block 220. Into the lowest
region of the upper ba~e area 222 of the block 220 there
is likewise recessed at least one threaded bush 223. In
Fig. 24, a further screw 228 is indicated ~imply diagram-
matically, with the aid of which the bsse plate 10 is
connected to the upper base area 222 of the block 220. It
goeg without ~aying that, in ca~e~ of unfl~t ~urfaces,
any of th~ known connecting m~ans can be us~d which is
a~pllc~ble in th~ case conc~rnod.

The brake 50 represented in Figs. 36 and 37 has
a sill 230, which can be pressed down and i~ located in
the middle region 15 of the main portion 10 of the
fastening means 2. From the underside of this sill 230
S there pro~ects a bolt 231, which i3 directed downwardq.
This bol~ 21 pasceæ through the anchorage plate 3 and is
coupled to one of the end portione 245 of a connecting
rod 232. The other end of the connecting rod 232 is
coupled to a mechanism 250, which i8 designed for execu-
tion of the braking operation.
The outline of the 8ill 230 may advantageously be
circular or rectangular (Fig. 36). The longitudinal axis
of the bolt 231 ad~oining the underside of the sill 230
coincides with the axis of rotation of the fastening
means 2 for one of the boots of the user, with th~ re~ult
that the actuation of the brake 50 is possible irres-
pective of the angular position of tha main portion 10 of
this means 2.
To receive the sill 230, a hou~ing 233 is made in
the middle region 15 of the main portion 10. This housing
233 is recessed into the middle section 15, with the
result that the bottom 234 of the housing 233 lies
underneath the surface 238 of the middle section lS. The
sill 230 itself has a bottom plate 235, which is, for
example, of sheet metal and which lies in the housing
233, to be precis~ above the bottom 234 of the same. On
the bottom plate 235 there i8 a block 236 of a compliant
material, for ex~mple of a suitable plastic, such as for
example of an elastomer, which is connected to the upper
side of the bottom plate 235. The upper side 237 of the
block 236 lies above the upper side 238 of the middle
section 15.
Connected to the underside of the housing bottom
234 is a piece of tube 238, the longitudinal axis of
which is approximately perpendicular to the housing
bottom 234 and in which the bolt 231 is mounted longitud-
inally displaceably. That section of the bolt 231 which
is located between the housing bottom 234 ~nd the bottom
239-o~ the main portlon 10 i8 surrounded by a spring 240,
20~0~4~
- 34 -
for example a helical spring. This sprlng 240 presses on
the underside of the bottom plate 235 and thereby retaina
the si.ll 239 in its upper position when no weight is
acting from above on the ill 230. In order to limit the
tra~el of the sill 230 caused by thix spring 240, the
section of the bolt 231 protrudlng from the piece of
tube 238 is provided with stop means 241. In the example
represented, a peg 242 serves as such a stop mean~, which
passes through the bolt 231 and the end portions of
which, protruding from the bolt 231, strike against the
lower edge of the piece of tube 238. However, a ring
which is fastened on the outside of the bolt 231 or the
like may also serve as ctop means 242.
The longitudinally displaceable connecting rod
232 rests (Fig. 37~ on the upper side of the base 1 of
the snow board and, in the region of the anchorage
plate 3, paSces through an elongate recess 244 in the
anchorage plate 3. The cross-section of this recess 244
corresponds to the cross-section of the connecting rod
232, in order that the latter is guided as freely as
possible but with as little clearance as possible in the
recQs~ 244. The connecting rod 232 may have, for example,
a rectangular cross-section, the longer side of this
profile re~ting on the base 1. In the region of the bolt
231, the connecting rod 232 has a broadened end portion
245 in which there is a through-opening 246. This opening
246 is made such that the lower end portion 247 of the
bolt 232 can be accommodated in this opening 246. The
side walls of the opening 246 are virtually at right
angles to the surface of the connecting rod 232. In the
region of the end edge of th~s end portion 24S of the
connecting rod 232 there i~ a sloping surface 248. This
sloping surface 248 begins st t:-e underside of the rod
end portion 245 and rises in the direction of the opening
246. The end of this sloping surface 248 i8 at a distance
from the edge of the opening 246, 80 that thi~ portion of
the rod end 245 represents ~ "run-up ramp" for the lower
ond 247 o~ th~ bolt 232.. Tho sharp edge or the beginning
: 249.of th~ ramp is thu~ at the bottom, i.e. virtually on
_ 35 ~ 5 4 4
the base 1.
In Fig. 37, the sill 230 is represented in its
lower, i.e. actuated position, as if there were a boot in
the fastening mean~ 2. Consequently, the lower end
portion 247 of the bolt 232 lies in the said opening 246.
As soon as the gill 230 i~ relieved, the spring 240
forces the bottom plate 235 upwards and the lower bolt
end 247 is drawn out of the opening 246 in the connecting
rod 232. This rod 232 is thereby freed and shifts to the
right under the effect of mechanism 250, with the result
that the opening 246 no longer lies underneath the bolt
231. The amount by which the rod 232 ~hifts to the right
is made long enough for the sharp edge 249 on the rod
ends 245 to lie underneath the bolt 231 or even a little
to the right thereof. When the braking element 55 i8
brought into its horizontal, i.e. ineffective position,
at the ~ame tima the rod 232 shifts again to the left.
The edge 249 of the ramp 248 is pushed underneath the
lower bolt end 247 and it then moves further until in the
position presented in Fig. 37. Then the user will put his
boot into the fastening means 2, as n result of which the
sill 230 is pressed down and the lower end 247 of th~
bolt 231 goes into the rod opening 246. As a result, the
rod 232 is retained in its said position, and conse-
quently 80 too is the braking element 55 coupled to the
latter.
The mechanism 250 (Fig. 36) comprises a retaining
plate 251, which is fastened on the base 1 with the aid
of screws 145. One of the edges of the retaining plate
251 i8 flu-~h with one of the side edges 54 of the base 1.
The braking element 55 has an approximately S-shaped
member 252, the middle portion of which is pivotally
mounted in an eye 52 on the retaining plate 251. The
inner limb of the braking member 252, located in the
region of the retaining plate 251, is in engagement with
a drive spring 253, which can bring the braking element
55 into its effective position when the brake i~
actuate~. The other limb of the braking member 252 lie3
ne~t to th~ side edge 54 of th~ base 1 and i8 intended

and de~igned in such a way that, if neces~ary, it
penetrates into the snow in order to brake the snow board
and thereby to prevent it sliding down the Rlope in an
uncontrolled way.
S A blocking peg 254, which i under the action of
a spring 255 and i~ additionally coupled to the outer end
of the connecting rod 232, is in engagement with the
braking member 252. When the connecting rod 232 i~ freed,
it relieveg the blocking peg 254 and the latter retracts
under the actLon of the spring 255. The braking element
55 is thereby freed for braking.
