H~LDER FOR TOOLS AND THE LIKE AT PERFORATED BOARDS
Previously kno~n holders o~ this kind are not able to adapt them- ;
selves to di~ferent dis~ances between holes, i.e. a differently
designed or dimensioned holder is to used :Eor each hole module.
Another drawback o~ known ~echniques resides in that the holders
easily become disengaged when subjected to heavy tools and/or
strain of any kind and thus fall off the board with the tool or
the like. Finally, further disadvantages are to be seen in ex-
pensiveness of the holders in production and use in spite o~ a
limited endurance.
An object of the invention is to counteract these drawbacks and
to eliminate them as far as possible. Furthermore, it is an ob-
ject of the invention to develop techniques in tllis field.
These objects are achieved according to the present invention by
a holder of the kind as initially defined, which is further cha-
racterized by the features set forth in the characterizing clause
of claim 1. Further characteristics of and advantages with the
invention are revealed by the following description with refe-
rence to ~he accompanying drawings showing by example non-limited
embodiments. -

Fig. 2 is a front view of the holder according:to Fig. 1,
Fig. 3 is a sectional view according to line III-III in Fig. 2,
Fig. 4 - 6 show a further embodiment according:to t~e present in-
vention corresponding to Fig. 1 - 3, respectively,
Fig. 7 is a rear view of the holder according to Fig. 1 - 3, and

present invention in a perspective, rear, front and under-
neath view, respectively.

W089/02~7 PCTISE88/00471
2 ~
The holder according to the invention shows a generally platelike
rectangular base 1, which uppermost is thickened to provide a
horizontal, ~raverse supporting beam 2 equippedwith preferably
throughgoing holes 3 arranged at right angle to the base plane
and provided to retain tool carriers or the like 4.
In its rear, upper area, the beam 2 is centrally furnished with
a rearwardly and upwardly projecting hook 5 having the shape of a
parallelepiped. and showing a bevel 6 in its rear lower area.
~elow the beam 2, the base is preferably furnished with lateral
recesses 7, between which there is centrally provided a circu-
lar opening 8. From the latter~ there e~tends downwardly a slot
9, which terminates freely at the lower end of the base while e~-
lS tending through and leaving free an intermediate, roughly rectan-
gular cu~-out portion 10. Into this cut-out portion is inserted a
locking member 11 abutting the front side o~ said base with a
rectangular plate 12, the front side of which sho~sa handle 13
designed as a central traverse rib. In said cut-out portion said
locking member is guided by a guiding part 14, which close to said
plate is designed thicker, which then within the rear area of the
base is recessed downwardly, and which then forms a guiding flan-
ge 16 extending upwardly and laterally within the plane of the
base, with which flange said guiding part is guided whithin an
enlargement 17 o~basel connecting to the cut-out portion 10. Part
14 continues rearwards and beyond base 1 and is terminated by a
claw 15, which points downwards.
It will be readily appreciated, that parts 1, ~ and 11 may be ma-
nufactured in one piece, ~espectively. Parts 4 are preferably ma-
de of metal, while parts 1 and 11 are made of plastic material,
e.g. by injection molding. In this way, a simple and economical
mass production is possible. ~s the holder is made in one piece,
except for the locking member, the holder is very rigid and able
to resist great strain. Even the locking member is rugged and
furthermore utmost protected.

The assembly is very simple. The tool carriersor ~like 4 may sim-
ply be pressed into ~he base, possibly even screwed in, as the
beam 2 is designed with great heigh~and depth, so that any ben-
ding is practically impossible even a~ great strain. Furthermore,
the beam lends itself to individual shaping, a~tachments etc.
Then, the locking member is introduced into the cut-out portion
10 turned 90~, i.e. with the claw 15 directed laterally, and
thereupon, the loc~ing member is twisted within the cu~-out por-
tion against the spring action of the bifurcated base to attain a
position according to the drawings, wherein the guiding flange
~rasps behind the enlargement and the ~ember is secured against
withdrawal. ~ vertical movement is, however, possible. Now, the
hook 5 is introduced into a chosen hole in a perforated board ob-
liquely from below and upwardly and then the holder is pressed a-
gainst the board, until the claw 15 glides into a fi~ting lowerhole. Thereupon, the locking member is pressed downwards by means
of the handle, until the root of the claw 15 rests upon the lower
hole walI and thus secures the holder in its entirety.The cut-out
portion lO may have any length, i.e. vertical extension. In this
way, it is possible to use the holder for as different distances
between holes as for instance 25 - 40 mm.
The third embodiment according to the present invention as shown
in Fig. ~ - 11 corresponds roughly to the first one. ~herefore,
same reference numerals have been used for corresponding parts
with the addition o~ " ''' ". Primarily different is the absence
of a cut-out portion 10. The slot 9''' is enlarged lowermost by wa
o~ roundings 22'''. The guiding flange 16'''surrounds the locking
member 14''' preferably all the way and is guided in an enlarge-
ment 17''', which opens downwardly. Finally, instead of one claw,there are provided two cl~ws 15''' and 15'''' pointing in oppo-
site directions. The surfaces of said claws which are facing the
holder are preferably arranged in different planes, i.e. at dif-
~erent distances from the holder to compensate ~or e.g. different
depthsof perforated boards. The underside is designa~ed with 19'''
and the lateral surfaces with 20'''.

W089/02347 PCT/SE88/00471
2~3~
In the modified embodiment according to Fig. 4 - 7, same refe-
rence numerals ~ith the addition o~ " '' are used for analogous
parts. There are no lateral recesses 7. Instead, there are provi-
de~ lateral ribs 18 extending from the beam 2 down to the lower
edge 19 of holder 1 within the lateral sides 20 of same conver-
glng like a wedge from the beam down to the lower edge. The said
ribs may be embossed even in relation to the beam and form a led-
ge 21, which malces a frame together with the ribs. This embodi-
ment is very rigid and resistant to torsion at the same time as
the locking mernber 11 is very much protected.
At its lower, free end, the slot 9 is pre~erably enlar~ed by way
of roundings 22 for readily inserting the locking member which
must, according to this embodlment, not necessarily be moveable
along the slot, i.e. apart from the movement of introduction, but
preferably is mounted with a rectangular, particularly square
guiding part 14 in a commensurate cutout portion 10 , through
the center o~ which the slot extends. The cutout portion has more
than twice the width of the slot, which means that the locking
member is to be inserted by elastically bending apart the two
halfs of the holder within their plane, whereupon the halfs move
towards each other, when the part 1~ has snapped into the cutout
portion to secure the locking member in this way.
The locking member 11 shows two guiding flanges 16 extending
laterally within the enlargement 17 of the base which is through-
going down to the lower edge 19 and, at distance from these flan-
ges, twoclaws 15 and 15 arranged at right angle in relation to
the flanges and pointing in opposite directions, one of which
claws is arranged at greater distance from the holder with its
side facing same than the other claw to compensate for different
depths of per~orated boards and possibly other deviations as well.'

The claws of this latter holder 1 do e.g. attain a horizontal
position when inserted in a hole in a perforated board. When now
the locking member is twisted 90~ against the spring action of
both halves of the holder, namely in one direction or in the
other, one of the claws grasps behind the lower hole edge and se-
cures the holder.
Universal utility of this embodimen~ may easily be achieved, e.g.
by providing along the slot several cutout portions, which are
separated from each other by short bridging parts. In this way,
the locking member is pressed into a cutout portion fitting the
actual perforated board, which portion accordingly corresponds to
space and/or dimensions of the actual holes.
The provision of the insides of the claws in different planes in
relation to the holder may also be used for elastically pressing
the holder area of the base enlargement against the perforated
board and thus secure the holder even safer.
It will be appreciated, that the claws may have other shapes,
e.g. even oval shape or the shape an eccentric disc.
