~indow and/or French Window for Buildings and 8ection for Use
with 8uch a Window and/or French Window
The invention relates to a window and/or French window for
buildings, especially outside doors for buildings according to
the preamble of claims 1, 3 and 25 and a section that corresponds
t~ the preamble of claims 33, 34 and 42.
For the purposes of this invention, doors for buildings are
especially also outside doors for buildings, such as, e.g.,
balcony or terrace doors or French windows for buildings.
The object of the invention is to demonstrate a window and/or
French window for buildings that is distinguished by an
especially small and compact casing section and especially also
ensures effective protection against weather for the leaf frame,
as well as improved anti-burglary protection.
To achieve this object, a window and/or French window for
buildings is designed according to claims 1, 3, and 25. A
section is designed corresponding to claims 33, 34, and 42.
The following, i.a., are common to all embodiments of the
nvention:
~ The respective system represents a very economical
solution; in particular, no additional outer covers of
the window or French window leaf are necessary.
~ The casing section that preferably consists of metal,
for example, aluminum or else also a high-strength,
fiber-reinforced plastic, has very slender or narrow
CA 02228916 1998-02-06
dimensions. Consequently, with building opening
predefined dimensions, larger glass surface areas and
thus higher light yield are possible.
~ The casing section has extremely good static and
dynamic values, despite its slender and narrow
dlmenslons .
~ The casing section does not absorb any moisture.
Therefore, no volume changes or disruptions of function
that are caused in this respect occur.
~ The invention ensures improved anti-burglary protection
since there is virtually no gap between the casing and
the leaf frame that would be suitable for the insertion
of a burglar tool.
For the purposes of this invention, "casing section" is
dlefined as a section from which, i.a., the outer portions of the
c~sing directly adjoining the masonry, and also steps of the
c~sing, etc. can be made.
The invention is explained in more detail below based on the
figures in the embodiments. Here:

In the description below, reference is made mainly to windows
for buildings, but the following description also applies to the
same exten1 to French windows for buildings. In Figure l, l is a
window leai~ with a leaf frame 2 that is formed from lengths of a
wood section and with an insulating glazing 3 that is arranged in
leaf frame 2.
A casing in which window leaf l is arranged to pivot and/or
to tilt is referred to as 4. The plane of the window opening is
referred to as M. Leaf frame 2 or the wood sections that form
this leaf i-ra~e have usual fold 5 on the outer periphery of the
leaf frame On the inside, leaf frame 2 is arranged with a
recess 6 that is open toward the opening and toward the outside
oi' window :Leaf l, in which insulating glazing 3 is held by means
of a pad, not shown, as well as by means of a section 7 that is
arranged on the outer side of the leaf; the latter with a
circumferential seal (8) (seal section) that completely covers
section 7 t:oward the outside and that adjoins the outside surface
of insulating glazing 3 has the function of a glass strip.
CA 02228916 1998-02-06
Section 7 is made of, for example, metal, e.g., aluminum or an
aluminum alloy. Seal 8 is formed by a circumferential section
that is made of rubber or a soft plastic. Seal 8 corresponds to
the inside of the window leaf of a seal 9 (seal section).
A characteristic of the window that is depicted consists of
the fact that casing 4 is formed by four rectangular adjacent
lengths of a casing section 10, which basically consists of two
section parts 10' and 10'' that are connected together via heat
insulation or a section part 10''' that forms an insulating
element. Section part 10', which is arranged on the outside of
the window, extends basically parallel to plane M of the window
opening and extends forward into this window opening of section
parts 10'' and 10''' to the extent that section part 10' forms
support or sealing surfaces for the outside of leaf frame 2 when
window leaf 1 is closed and completely covers the outside of leaf
frame 2 that is parallel to plane M when window leaf 1 is closed
toward the outside, so that, viewed from outside, i.e. especially
also with respect to outside weather influences, the window in
t;he closed state corresponds to a metal window. In the sectional
view of Figure 1, two section parts 10'' and 10''' lie basically
p,_rpendicular to plane M, whereby section part 10'' extends up to
t]he inside of the window and adjoins the outside of the window at
section part 10'' of section part 10''', which is arranged
between section parts 10' and 10''.
A characteristic of casing section 10 consists of the fact
that the l~tter has only a small overall height; the existing
window or building opening is thus reduced to only a small extent
CA 02228916 1998-02-06
by casing 4. For this reason, the window that is depicted in
F:Lgure 1 o:r casing 4 there is also especially suitable for the
restoratio]n or renewal of building windows if, in this case, an
o:Lder, still usable casing is to be left in the respective window
opening in order to avoid major work, especially masonry work.
A~Eter suitable cutting and/or raising and/or notching of the
existing c;lslng, casing 4 is then fastened in a suitable way to
the latter. In the embodiment depicted, casing section 10 shows
in particular the design that is described in still more detail
below.
In the embodiment depicted, section part 10''' consists of
two strip-like elements 11 made of an insulating material, which
form a thermal gap and in each case snugly engage at their two
edges in recesses of adjoining section part 10' or 10'' and
between them form a closed channel-like cavity 12 that is closed
to the outside and that extends perpendicular to the drawing
plane of Figure 1 and which are molded flat on their external
surfaces, ;so that on the outside a basically rectangular cross-
section is produced for section part 10''' in the cross-section
view of Figure 1, specifically with surfaces that are
perpendicular to plane M.
Section part 10' consists basically of a wall section 13,
which, with casing 4 installed, lies in a vertical plane, i.e. in
a plane that is parallel to plane M and at its free end, i.e., at
some distance from section part 10''', turns into an oblique,
rising wall section 14. With its open edge and with the open
edge of an additional rib 15 that is molded on below wall section
CA 02228916 1998-02-06
1~, this wall section 14 forms support surfaces against which
seal 8 rests when window leaf 1 is closed. Owing to the oblique
outlines both of the outside surface of seal 8 and the top side
of wall section 14, an outer drain for rain water is formed.
Where ection part 10''' rests on section part 10', section
part 10 is arranged on the inside with a wall section 16 that is
parallel to wall section 13 and at some distance from the latter.
Wall sections 13 and 16 are connected together via an upper rail
17 and a lower rail 18. In the area of rail 17 a receptacle for
a circumferential outer seal 19 that is arranged on casing 4 is
formed, against which closed window leaf 1 rests tightly with the
outside of leaf frame 2. To ensure a snug connection between two
elements 11 and section part 10' three strip-like projections 20
and 21, which also extend in the direction perpendicular to the
drawing pllne of Figure 1 and of which the middle projection is
widened in a dovetail shape at its free end, have their wall
section 16 on the side that faces away from rails 17 and 18, in
such a way that between, in each case a projection 20 and
projection 21, a dovetail-shaped opening is formed for the snug
connection of elements 11.
Section part 10'' consists of a wall section 22 that directly
adjoins section part 10'' which is parallel to plane M and in
turn has projections 20 and 21 on its side that faces section
p.~rt 10'''. In addition, section part 10'' has foot-like or
s1_rip-like wall sections 23-25 which in each case are arranged
Oll the outside of casing 4 and are also parallel to plane M and
turn into a bend 26 or 27 at their lower free ends in each case
CA 02228916 1998-02-06
in Figure L. Each bend extends in the shape of a strip in the
d:Lrection perpendicular to the drawing plane of Figure 1.
Wall sections 22-25 are connected together via rails 28, 29,
30, which in each case lie in planes that are perpendicular to
p:Lane M. :[n the area of wall section 22 and rail 28 there, a
receptacle or groove 31' for an internal circumferential seal 31
that is arranged on casing 4 is formed, against which leaf frame
2 rests in the area of fold 5 when the window leaf is closed.
As Figure 1 additionally shows, wall sections 16 and 22 are
arranged over the top side of section part 10''', so that between
these wall sections and above section part 10'',' and thus also
between seals 19 and 31, a channel is formed in which water can
collect. Through an opening 32 in wall section 16 and an opening
3:3 in rail 18, this water can then run off to the outside. Since
wall section 13 projects downward over rail 18, opening 33 is
arranged in a protected way, so that for this purpose, water
cannot penetrate from the outside into the water collecting
channel or else only in the space of section part 10' that is
formed between rails 17 and 18 if wind is present. In the
d:irection of the width of the window, i.e., in the direction
perpendicuLar to the drawing plane of Figure 1, openings 32 and
33 are off;et with respect to one another.
Figure 1 shows a section through the lower, horizontal part
of window Leaf 1 and casing 4. It is understood that both leaf
frame 2 and casing 4 are designed alike all the way around, i.e.,
including :in the vertical sections and in the upper horizontal
CA 02228916 1998-02-06
11
section, whereby water outlet openings 32 and 33 preferably are
a:rranged facing only in the downward direction, however.
It was also assumed that window leaf 1 can be tilted and/or
pivoted. It was also basically possible, however, when using
same casing 4, to provide a solid glass field, with the advantage
that this solid glass field and the window leaf that can tilt
and/or pivot, when viewed from the outside of the building, look
alike.
On the inside of the window, casing section 10 or section
part 10'' can be covered by a shield or covering ridge that is
made of wood or aluminum, as indicated by dashed lines in Figure
1 at 34, so that the inside of the window gives the impression of
a wooden window, at least when it is closed. At the same time
shield 34 is then also used as an additional seal between the
outside surface of casing 4 and the boundary area of the window
opening thlt encloses this casing.
Figure 2 shows a vertical step 35, which is a component of
the casing that is otherwise not shown, as well as two window
leaves 1 in the closed state with, in each case, a leaf frame 2.
W:indow step 35 is formed by two casing sections 10, which with
their outsides that face bends 26 and 27 are arranged facing
parallel to one another and some distance apart. Two casing
sections 10 are connected together by a connecting and spacer
section 36, which in the embodiment depicted is constructed
basically as a double-T-section with a T-leg 37, which engages
in, in each case, a recess of casing section 10 that is formed
between wall sections 22 and 23 and with a clamping or holding
CA 022289l6 l998-02-06
12
s1:rip 39 that is arranged on other T-leg 38, which are made of,
for example, plastic, in which recesses of casing section lO that
is formed between wall sections 24 and 25 engage and bends 27
that are located there snugly engage from behind. In addition,
connecting piece 36 has locking elements 40 that act like a bow
spring and engage in the recesses of casing section 12 that are
formed between wall sections 23 and 24 and snugly engage from
behind bends 26 and 27 that are located there. As Figure 2
shows, the connecting piece extends only between section parts
l()''. In 1:he area between section parts lO''', a sealing strip
4~L (sealing section) that is made of rubber or plastic is
arranged on the outside of step 35, which closes the gap there
between two casing sections lO.
The rest of the design of casing section lO and leaf frame 2
correspondc; to that described above in connection with Figure l.
An extension of connecting piece 3 6 to the inside of the
wi.ndow is indicated as 3 6' by dashed lines. This extension is
used if, for example, increased strength for window step 35 is
necessary and/or window step 35 is to be anchored in a building
part in some other way.
As anot:her possible embodiment, Figure 3 shows a window step
3~ia, which is distinguished from window step 35 basically only in
that not two casing sections lO that are connected together are
provided, but rather these sections are combined together in a
common sect:ion lOa, which in terms of its design corresponds
ba.sically t:o double section lO, whereby, however, instead of two
CA 022289l6 l998-02-06
13
external section parts 10', a through-going section part lOa' is
p]ovided.
Finall~y, in a partial view and in a horizontal section,
F:igure 4 shows two window leaves in the area of a cuff 42 that is
formed between the two leaves when a window is closed.
Left w.indow leaf 1 in Figure 4 has in turn leaf frame 2 of
the window of Figures 1-3. Right window leaf la in Figure 4 has,
in the area of cuff 42 to which the closed window leaves directly
adjoin, a :leaf frame section 2a, in such a way that vertical gap
4:3 on the .inside of the closed window runs exactly midway between
the window leaves; the closed leaf parts are thus arranged to
look exact.ly alike in the area of the cuff.
To the outside of the window or leaf frame 21 is fastened a
metal sect.ion 44 that forms the cover, which has circumferential
outer seal 19, against which leaf frame 2 rests when the window
i-; closed. In addition, at its end away from leaf frame 2a
section 44 forms the support surface for seal 8 of window leaf 1.
A1 its other end, section 44 additionally forms a support surface
w:ith which this section seals against seal 8 of window leaf la.
A characteristic of the window of Figure 4 consists of the
fact that :in each case the lower and upper horizontal part of the
casing is :Eormed by a casing section 10, which is made through-
going over the entire width of the window. In the area of cuff
4.', wall section 14 of each of these casing sections is recessed,
specifical:Ly in such a way that when window leaves 1 and la are
cLosed, section 44 fits into respective recess 45, whereby
section 44, when the window is closed, extends above and below
CA 02228916 1998-02-06
14
respectively into the space of casing section 10 that is formed
between wall sections 13 and 14.
Figure 5 shows a section that is similar to Figure 1, in this
case with a renovated window for buildings. In this case, casing
03r casing section 10 is fastened partially to an already present,
old and milled-off casing 46 that is made of wood and protrudes
somewhat outward into the window cavity. For thermal insulation,
the space between the casing section and the fold is filled with
an insulating material 47. In addition, a sealing section or
sealing st:rip 48, which at the same time also seals gap 49
between ma,onry 50 and old casing 46, is located under the
section th;~t provides thermal insulation and is formed by
e:Lements 11.
Anothe:r possible embodiment is depicted in Figure 6. In this
f:Lgure, 35b is a horizontal or vertical solid step of a casing,
which in turn consists of two section parts lOb and lOb' that
correspond to section parts lOa and lOa', which are connected
together by elements 11 to ensure thermal separation. Sections
lt)b and lOb' are, in turn, for example, metal sections or
sections that are made of aluminum or an aluminum alloy.
The two leaf frames that are made of wood and that adjoin one
another in the area of step 35b when closed are referred to as
2b. The latter are designed in the area of their outlying fold
in such a way that when leaf frame 2b is closed, a recess 51, in
which step 35b is completely accommodated, is formed between the
latter. V:iewed from the inside lying above Figure 6, step 35b is
covered by two closed leaf frames 2b, in such a way that between
CA 02228916 1998-02-06
the latter only one slot 52 is visible, whose width is equal to
that of the slot that also remains at the other edge of
respective leaf frame 2b between the latter and the casing, for
example belween leaf frame 2b and the shield or covering strip 34
that is arranged on the inside of the window and/or French window
for buildings. When any leaf is closed, a circumferential slot
oi~ uniform width is thus produced.
In the direction perpendicular to the plane of closed leaf
frame 2b, step 35b has a dimension that is smaller than the
thickness of leaf frame 2b in this axial direction.
As already described above in connection with Figure 3, in
this embodiment as well closed leaf frames 2b are also completely
covered by section lOb', which rests with its two edges against
seal 8 of closed window leaf 1 or leaf frame 2b, on the outside
in the area of step 35b.
A special advantage of the embodiment of Figure 6 also
consists o:E the fact that leaf frame 2b can be designed
identically in each case, in such a way that, when viewed from
the inside of the window, these leaf frames have the same width
in the area of steps 35b, which cannot be seen when leaf frames
2b are clo:;ed.
Basically, it is possible to make some or all of the above-
described :;ections at least partially out of plastic. Thus, Fig.
7 shows a window leaf lc, whose leaf frame 2c is made from a leaf
frame section 53, which is produced as a plastic hollow section
w:ith severill self-contained chambers, specifically with an
internal, externally covered reinforcement section 54 that is
CA 02228916 1998-02-06
16
a:rranged in the area of the inside of the leaf and that is made
of metal, preferably steel, and in this case preferably of
stainless steel. Otherwise, on the outside leaf frame section 53
has the same section shape or fold 5 as leaf frame 2. Casing
s,ection lOc is very similar to section 10. In each case, on the
inside of the window opening that is grasped by this section, the
s;hape or shaped piece of casing section 10c corresponds to the
shape and shaped piece of section 10.
In the embodiment of Fig. 7, the casing is formed by casing
section loc which, corresponding to section 10, has outer section
part 10c' that is made of metal and inner section part 10c'',
which is also made of metal, as well as sections 10c''' which
connect these two section parts. Section part 10c' corresponds
to section part 10'. Section part 10c'' is distinguished from
section part 10'' basically in that, parallel to the rail or wall
section 29, another wall section 29' is arranged in the area of
the outer periphery of the casing. Wall sections 23, 24 and 25
with bends 26 and 27 are then arranged on this other wall section
or rail. Rails 23 and 25 simultaneously also connect two wall
sections 29 and 29' to a closed hollow section.
In addition, in Fig. 7, different areas in which holes for
discharging water can be inserted into section part 10' are
referred to as 33c.
Casing sections 10, 10a, 10b, 10c and corresponding leaf
frames 2, 2a, 2b and 2c form a total system for windows or French
windows, which is also especially characterized in that on the
outside the leaf frame of the closed leaf is completely covered
CA 02228916 1998-02-06
17
by section part 10', lOa' or lOc', and thus basically only
insulating glazing 3 is visible from outside. Another
characteri,tic of this system also consists of the fact that in
the closed state leaf frame 2, 2a, 2b and 2c is completely inside
casing 4, i.e., no cover that covers the inside surface of the
casing is needed, especially on the inside of the respective leaf
frame.
Figure;s 8-17 relate to a system which retains the above-
mentioned optical design on the inside of the door or French
window for buildings, in which, however, on the outside the leaf
f:rame is arranged with a specific leaf-frame outer section and is
covered by said outer section, which when the leaf is closed is
connected to the casing section. When the leaf is closed, its
exterior is in turn covered by sections, but an optical
separation is provided.
In Fig. 8, ld is a window leaf with a leaf frame 2d that is
formed from lengths of a wood section and with insulating glazing
3 that is arranged in this leaf frame. The casing is referred to
as 4d. Window leaf ld can be arranged to pivot and/or to tilt in
t]he latter. The plane of the window opening is in turn referred
to as M. Leaf frame 2d or the wood section that forms this leaf
frame has the section shape that was already described in
connection with leaf frame 2, specifically with usual fold 5 on
t]he outer periphery of the leaf frame and with recess 6, which is
o]pen toward the opening as well as toward the outside of leaf
frame ld and in which insulating glazing 3 is held in place by
m,eans of the pad, not shown, as well as by means of an additional
CA 02228916 1998-02-06
18
leaf-frame outer section 55, which in this respect also assumes
the function of a glass strip. In the case of a simple window
leaf or French window leaf, a total of four adjoining leaf-frame
outer sect:Lons 55 are fastened to the outer surface of leaf frame
2cl in such a way that the outer surface is completely covered by
acljoining :Leaf-frame outer sections 55.
Leaf-frame outer section 55, which is made from metal, for
example, a:Luminum or aluminum alloy by extrusion, consists of
several wa:Ll or section parts, which in each case extend over the
entire length of leaf-frame outer section 55. The outside
surface of this section is mainly determined by wall section 56
which, when leaf-frame outer section 55 is mounted on leaf ld,
l:Les in a plane that is parallel or basically parallel to the
p:Lane of insulating glazing 3. In the view that is selected for
F:Lg. 8, at its upper area that extends in the longitudinal
d:Lrection wall section 56 turns into two wall sections 57 and 58
that run perpendicular to the plane of wall section 56, which
w:Lth their free edges 57~ and 58~ that are some distance from
wall section 56 and that extend in longitudinal direction of
leaf-frame outer section 55, adjoin the outer surface of
insulating glazing 3.
Leaf-f]ame outer section 55 turns into a wall section 59,
which is some distance from the side of wall section 56 that
faces leaf frame 2d, on the longitudinal side that is some
d:Lstance f]om wall sections 57 and 58, specifically in a plane
that is pe]pendicular to the plane of wall section 56. At its
end that is some distance from wall section 56, wall section 59
CA 02228916 1998-02-06
19
turns into another wall section 60. This recessed wall section
60, which lies in a plane parallel to the plane of wall section
5~;, protrudes over edge 56' of wall section 56 to casing 4d that
extends in the longitudinal direction of leaf-frame outer section
55. Wall ,ection 60 is hooked at its end 61 that is some
d:istance f;rom wall section 59, specifically in such a way that in
the area oE this end, a groove 62 that extends over the entire
length of leaf-frame outer section 55 and is open toward wall
section 57 is formed, specifically at the side of wall section 60
that faces away from wall section 56 and between this wall
section 60 and a leg-like wall section 63. Externally, a rail-
l:ike wall section 64, which lies in a plane that is perpendicular
to the plane of wall section 56 and whose free edge rests against
the outside surface of leaf frame 2d, is molded onto wall section
63.
On the side of wall section 57 that faces wall section 60, a
groove 65 1hat extends over the entire length of leaf-frame outer
section 55 and that is open toward groove 62 is formed, which
liies in a common plane with groove 62, whereby said plane is
parallel to the plane of wall section 56.
Two grooves 62 and 65 are used to fasten leaf-frame outer
section 55 to leaf frame 2d by means of holding clips 66. The
latter consist of lengths of a basically U-shaped metal section,
for example, a section that is made of aluminum or an aluminum
a]loy. On a yoke-like wall section 67, each holding clip has two
leg-like wall sections 68 and 69 that are some distance from the
common side of this wall section, which turn into wall section 70
CA 02228916 1998-02-06
or 71 that is angled toward the outside at its free end and which
are designled in the shape of strips and lie in a common plane
that is parallel to the plane of wall section 67. On the side
that faces away from wall sections 68 and 69, a rail-like wall
section 72 is molded approximately in the center on wall section
67, which is some distance at right angles from the side of wall
section 67 that faces away from wall sections 68 and 69.
Individual holding clips 66 are produced by cutting off from the,
e.g., extruded section that has wall sections 67-72. For
fastening ]holding clips 66, leaf frame 2d is provided on the
outside with a slot 73, into which wall section 72 is inserted,
and that i, open toward this outer side and is perpendicular to
the plane of insulating glazing 3. Then, a hole is introduced
into the leaf frame and wall section 72 from fold 5 of leaf frame
2d. A locking pin 74 is then pressed or driven into this hole,
in such a way that holding clips 66 which engage with their wall
sections 70 and 71 in grooves 65 or 62 and also leaf-frame outer
section 55 on leaf frame 2d are held in place with the latter.
Between these free edges 57' and 58' and the outer surface of
insulating glazing 3 is arranged a seal 75 which, in the
embodiment depicted, consists of two components, specifically,
for example, a prefinished sealing section or sealing strip (dry
g:Lazing system) and a hardening sealing compound (liquid glazing
system) that is applied in addition after the insulating glazing
and leaf-frame outer section 55 are applied. Of course, it is
possible for seal 75 to consist entirely of the prefinished
sealing section or else an applied, hardened sealing compound.
CA 02228916 1998-02-06
21
Seal 9 thal is arranged on the inside can also be designed in the
same way.
In the simplest case, casing 4d is formed from four lengths
of a casing section lOd that adjoin one another at right angles,
whereby in turn said casing section consists basically of two
section parts that are made of metal, for example, aluminum or an
a:Luminum alloy, specifically of section part lOd' that is
arranged on the outer side of the window and section part lOd''
that is arranged on the inside. The two section parts are
connected together by section part lOd''' that forms heat
insulation or an insulating element.
As Fig:;. 8 and 27 show, section part lOd'' is identical to
section part lOc'', and section part lOd''' is identical to
section part 10''' or lOc'''. Section part lOd' is basically
d:Lstinguished from section part lOc', i.a., only in that this
section part has a small height in comparison to section part
l()c' and i; also designed as a closed hollow section with two
parallel wall sections 76 and 77, of which internal wall section
76 that faces, i.e., section part lOd''', has projections 20 and
2:L on its side that faces away from wall section 77, between
which elements 11 of section part lOd''' that are used for a
thermal gap are held in place. Two wall sections 76 and 77 that
are arranged some distance apart and parallel to one another are
connected l_ogether by two rail-like wall sections 78 and 79.
Lower rail--like wall section 79 in Fig. 8 is located
approximately in the area of the center plane between elements
l~L. While wall sections 78 and 79 are parallel to the planes of
CA 02228916 1998-02-06
22
elements 11, wall sections 76 and 77 are perpendicular to these
planes. At its upper end in Fig. 8, section part lOd' has
another wall section 80, which originates from the connecting
point of wall sections 77 and 78 and, viewed from the outside of
t~he window, is curved in a convex manner just like wall section
5;B. Between the free end of wall section 80 and the transition
between wall sections 78 and 76, a seal 81 is provided which
rests against the outer surface of recessed wall section 60 of
l,_af-frame outer section 55 when window leaf ld is closed. Also
in the embodiment that is depicted in Fig. 8, further internal
seal 31 is arranged in addition to outer seal 81. Both seals are
dl_signed as closed, circumferential seals.
As Fig. 8 further shows, end 56' of wall section 56 that
p:rojects downward over wall section 59 forms a water drip edge.
Owing to the above-described offsetting of wall sections 56 and
60 (wall section 56 projects further over the outside surface of
leaf frame 2d than does wall section 60), this water drip edge is
located approximately in the center over wall section 80, in such
a way that water that drips from leaf-frame outer section 55 is
d:rained off downward on the outside surface of section part lOd'.
Fig. 9 shows a, for example, vertical step 35d, which is a
component of the casing, otherwise not shown, as well as, in the
closed state, two window leaves ld with one leaf frame 2d in each
c.~se. Window step 35d consists of a step or casing section lOe,
which in principle is formed from two casing sections ld that are
arranged a, mirror images in a center M' plane and are connected
together, ,pecifically with outer section part lOe', inner
CA 02228916 1998-02-06
23
section part lOe'', in each case made of metal, and center
section parts lOe'''. Two elements 11 that are used for a
t]~ermal gap are provided only twice, as was described above also
in connection with Fig. 3 for step 35a mentioned there.
Two window leaves ld are in turn designed in the same way as
was described above in connection with Fig. 8. This also applies
especially to leaf-frame outer section 55 and its fastening, as
w,ell as with respect to the fact that respectively closed window
l,eaf ld rests with recessed wall section 60 of leaf-frame outer
s,ection 55 against the respective free end of outer section part
lOe' that is designed as a mirror image with respect to center
plane M'.
Unlike section part lOd', section part lOe' is not
constructed as a closed hollow section. Rather, in each case
s,ection part lOe' has on each side from elements 11 a groove-like
s,_rew channel 82 that extends over the entire length of the
s,ection and is open to the inside.
Plane M' lies perpendicular to plane M of the window opening
at the same distance from and parallel to elements 11.
Two additional screw channels 83 are arranged on the inside
at section part lOe''. With the aid of these screw channels and
s,crews that are engaged in the latter, step 35d that is cut to
l,ength or countered at its ends, for example corresponding to
c,asing section lOd, can be fastened to the casing.
In a view similar to Fig. 9, Fig. lo shows in turn step 35d,
w]hereby window leaf ld that can swivel and/or tilt with leaf
frame 2d is provided on only one side of this step, while a solid
CA 02228916 1998-02-06
24
field 84, which has insulating glazing 3 that is held in place
with a pad 85 directly on step 35d or on section lOe, adjoins the
other side of step 35d. In this case, pad 85 supports internal
section part lOe'' and external section part lOe', specifically
in each case at projections 20. Insulating glazing 3 is held in
place on its outer side in the area of its edge at the external
circumferential seal 86 by section part lOe'. Internally,
insulating glazing 3 is held in place via inner seal 9 by a glass
strip 87 that is made of wood. The latter snugly engages
directly into this section part with a side that is matched to
the section of section part lOe''. As Fig. 10 further shows,
glass stri]p 87 is arranged on the inside with a circumferential
recess 88 in such a way that on the inside of the window between
the glass strip and step 35d, but also between this glass strip
and the casing, a visible seam is formed that corresponds to the
seam between leaf frame 2d and step 35d or the casing. For
w:indow leaE ld and solid field 84, a basically identical optical
appearance is thus produced inside, as is depicted in very
s:implified form in Fig. 11.
In a simplified partial view and in a horizontal section,
F:ig. 12 shows two window leaves ld and le in the area of a cuff
8~3 that is formed between the two leaves. Lower window leaf ld
in Fig. 12 that is made of wood has in turn leaf frame 2d with
leaf-frame outer section 55. In Fig. 12, upper window leaf le
that is made of wood has leaf frame 2e with leaf-frame outer
section 55, as well as with an additional cuff section 90 that is
also made of metal, preferably, aluminum, and that forms the
CA 02228916 1998-02-06
cover. This section basically comprises a U-shaped wall section
91, which is fastened via a molded wall section 92 to leaf frame
2e, specifically in the embodiment depicted in the area of fold 5
by means of locking pins 74. In one leg, wall section 91 lies
against recessed wall section 60 of leaf-frame outer section 55
of leaf frame 2e. With the other leg, wall section 91, when the
window is closed, rests against wall section 60 of leaf-frame
outer section 55 of leaf frame 2d. A characteristic consists of
the fact that the outside surface of cuff section 90 or of wall
section 91, when the window is closed, lies in a common plane
with the outside surface of leaf-frame outer section 55 or its
wall section 56.
Fig. 13 shows a window leaf lf with a step 93 that is
provided on the leaf frame. Section 94 that is used for the step
is designed similar to casing or step section 10e, except with
smaller dimensions in terms of width and depth, i.e., the step
section consists of an external section part 94' that is made of
m~etal, which corresponds in form to section part 10e', and an
internal step section 94'' that is made of metal. Between these
slection parts, section part 94''' that is formed in turn from two
elements 11 is arranged. Via circumferential seals 95, section
part 94' rests on both sides in each case against the outside
surface of an insulating glazing 3 in the area of the periphery
of this insulating glazing. Outside step 93, seal 95 turns into,
for example, seal 75 of Fig. 8. On the inside, a section or
covering ridge 96 that is made of wood is arranged that rests via
internal circumferential seals 9 against the inner surface of the
CA 022289l6 l998-02-06
26
insulating glazing. Covering ridge 96 has a groove-shaped recess
97, which extends over the entire length of covering ridge 96 and
is open toward the plane of insulating glazing 3. Several U-
s]haped hol~ding clips 98, which are made of, for example, plastic
or metal, are fastened in recess 97. Covering ridge 96 can be
f~stened with these U-shaped holding clips by clipping to section
part 94'', which protrudes over the plane of the inner surfaces
oE insulating glazings 3. For this purpose, legs 98' of holding
clips 98 form detentes that engage rasterings on section part
94''.
As a further embodiment, Figures 14 and 15 show a solid field
99 in a casing that is formed by casing section 10d. The solid
field consists in turn of insulating glazing 3, which is held in
place by means of pad 85 directly on casing section 10d,
specifically in each case on projections 20 of section part
10d''' that face pad 85. On the outside, insulating glazing 3 is
supported via circumferential seal 100 on section part 10d' and
on the inside via circumferential seal 101 on a glass strip 102
that is fo:rmed by a wooden section. The latter is arranged on
its peripheral side that faces away from the window openings with
a glass st:rip-holding section 103, which is fastened via a
fastening ,ection 104 to section part 10d.
Two sections 103 and 104 are made in each case of metal or
v:iscous plastic. The glass strip-holding section is basically
designed a:; a C-section with two legs 103' and 103''. Leg 103'
has a detente 105 on an extension 103''' (Fig. 15). Fastening
section 104 has, i.a., a first leg 104', which can be gripped
CA 02228916 1998-02-06
27
f:rom behind by leg 103'', as well as a second leg 104'' with a
detente 106 that forms a counterlock for detente 105. With the
aid of a clamping section 104''', fastening section 104 can be
mounted on section part lOd'' and fastened there in groove 31' by
clamping. After fastening section 104 is mounted, the glass
strip that was pre-mounted with glass strip holding section 103
is then pushed open from the inside of the window, i.e., in an
axial direction that is perpendicular to the plane of insulating
glazing 3, specifically in such a way that leg 103'' moves under
lleg 104', extension 103''' moves under leg 104'', and detente 105
engages behind detente 106.
Fig. 16 shows the casing, as well as a door leaf lg in the
lower, horizontal area. Casing section lOf is distinguished from
casing section lOd basically only in that section part lOf' which
corresponds to section part lOd' is made extremely low and has a
w~ll section 107 that slopes off instead of upper, concave arched
w~ll section 80. Wall section 78 is located in the plane of
u]pper element 11 in Fig. 16. In two wall sections 76 and 77,
w~ter flow openings or holes 108' and 109' are arranged directly
a;bove wall section 78. A circumferential seal 110 is held in
place on the side of wall section 76 that faces away from wall
sl_ction 77. Water flow openings 108' and 109' are used to remove
water from the water collection channel that is formed above
upper element 11. The space between two elements 11 is filled
with a filler material that insulates but that can support loads,
for example plastic high-resistance foam 111.
CA 02228916 1998-02-06
28
Instead of leaf-frame outer section 55, a leaf-frame outer
section 55a is used that is made flatter than leaf-frame outer
section 55, but that has wall section 56 and especially recessed
wall section 60, with which this section 55a rests directly
against the outside surface of leaf frame 2g. With the aid of a
material rail 112 that is molded onto the inside of wall section
56 and a bend 113, section 55a is held in place on leaf frame 2g.
Fig. 17 shows an embodiment similar to Fig. 16 in the case of
a door leaf lh with leaf frame 2h. A leaf-frame outer section
5';b, which corresponds to leaf-frame section 55 in terms of its
design but has a somewhat greater height, is fastened to the
outside surface of the leaf frame. For fastening, holding clips
6~ja are used, which are distinguished from holding clips 66
basically only in that two wall sections 72 that are some
distance from the back side are provided, which in each case
engage in a slot 73 in leaf frame 2h, in such a way that each
holding cl:ip is held in two places over each locking pin 74.
On leai~-frame outer section 55b, section 114 that is used as
a water repeller is then attached to the lower edge of wall
section 56 with a wall section 114' that runs toward the outside.
A characteristic consists of the fact that the lower,
horizontal portion of the casing is formed by a casing section
10g, whose inner and center section parts 10'' and 10g'''
correspond to section parts 10d' and 10d'', whose outer section
pclrt lOg' LS defined basically as an H-section, but namely with
two shortened wall sections 76 and 77 and wall section 79 that
connects to the latter, whereby wall section 80 is eliminated,
CA 02228916 1998-02-06
29
and from wall section 78 only two rails that extend inward and
lie in the plane of upper element 11 remain. A cover section 115
that is mal~e of an elastic material, for example elastic plastic,
i, fastened to casing section lOg. The latter covers section
parts lOg' and lOg''' and is held in place, on the one hand, with
an area on this leg that surrounds leg 22 and, on the other hand,
with an area that extends from above to section part lOg' on this
section part. The top side of cover section 115 slopes off to
the outside. Covering section 115 simultaneously forms a seal
that works together with leaf frame 2f. The embodiments of
Figures 16 and 17 are distinguished in each case by a low
t]hreshold height. In these figures, in each case, the level of
t]he adjoining floor is indicated by 116. In the embodiment of
Fig. 17, the threshold height is extremely low and is, for
example, only about 17 mm.
Below, a new type of step connection will now be explained in
connection with Figures 18-21.
In a simplified, partial view, Fig. 18 shows three step
s,ections lOe that are connected to form a cross-step, of which a
t]hrough-going step section forms vertical step 35d and two step
s,ections lOe on vertical step 35d form laterally adjoining
horizontal steps 117. To connect step section lOe, two pairs of
two holes 118 apiece are provided in the step section that forms
vertical step 35d or in section part lOe'' that is located there.
Holes 118 of each pair are coaxial to one another and are
arranged perpendicular to center plane M'. In the view of Fig.
13, the pairs of holes lie perpendicular to the reference plane
CA 02228916 1998-02-06
of this figure behind one another in such a way that only one
p~ir of holes 118 is visible. Holes 118 intersect the two screw
channels. The distance between each hole of a pair and the
corresponding hole of the other pair in the direction of
longitudinal extension of step 3Sd is equal to the distance
b~_tween screw channels 83. In holes 118 connecting pins 119 are
arranged which at both ends are some distance from section part
llDe'' and in each case engage in a screw channel 83 of section
lOe of adjoining step 117 and are held in place there by a
clamping support. A cross connection between section parts lOe''
of steps 35d and 117 is thus produced via pins 119.
Section parts lOe' of steps 35d and 117 are also connected
together via pins 120. Two holes 121 which are offset in the
longitudinal direction of this step are arranged in the two
longitudinal sides of section part lOe' of section lOe of
vertical step 35 (Fig. 20). Holes 121 are as far apart as two
screw channels 82 on section part lOe'. In each case a pin 120
i; arranged in screw channels 82 of section part lOe' of
horizontal step 117. Each pin 120 extends with its end into a
hole 121 in such a way that section parts lOe' are also
connected together. Likewise at the ends that are some distance
from the cross joint section parts lOe' of steps 35d and 117 are
connected to the casing or to section lOd that forms this casing
i.e. hole~ 121 which are parallel to wall sections 76 and 77 as
well as perpendicular to the planes of wall sections 78 and 79
are arranged in section part lOd' or in wall sections 78 and 80
that are located there. The mounting of a cross step 35d/117 is
CA 02228916 1998-02-06
31
done in such a way that first steps 35d and 117 are connected in
t]he above-described way to the cross joint of Fig. 18 via pins
119 and 120. Then, the thus finished cross step is used in the
previously finished casing. Then, the pins that are in screw
c]hannels 82 of section part lOe' are moved from the inside of
tihis section part into holes 121 of section part lOd' of the
casing with a suitable tool, for example, a screwdriver, to the
extent that each pin 120 lies with part of its length in a screw
c;hannel 82 and with another part of its length in hole 121. This
connection between casing 4d and steps 117 is made possible by
the fact that screw channels 82 or their slots are accessible
from the back side.
Fig. 21 shows the connection between the step section or
slection part 94' and leaf-frame outer section 55. This
connection, too, is produced in an analogous way using two pins
120 in each case, which are arranged in screw channels 82 of
s,ection part 94'. Screw channels 82 or their slots are in turn
a,-cessible from the inside of section 94 in such a way that pins
120 can be pushed into holes 121 that are provided in leaf frame
outer section 55.
Fig. 22 shows a window cuff 42a that is similar to cuff 42 of
Fig. 4 between both leaves 1 and la. Instead of metal section
44, a somewhat taller metal section 44a is used, which has leg
44a' and extends with its outside surface approximately up to the
plane of the outside surface of wall section 13 of outer section
part 10' of casing section 10, which is not shown in Figure 22.
CA 02228916 1998-02-06
32
Just like cuff design 42, cuff design 42a can also be the
connection between a window leaf 1 that can pivot and tilt and a
solid field, which is provided instead of leaf la and in which
leaf-frame section 2a then forms a solid step, for example, a
vertical step, that is fastened to the casing.
In vertical section, Figures 23 and 24 both show a window
arrangemenlt in the area of a horizontal step 122 or 123. The
sleps are made of, for example, wood. Step 122 is a component of
a solid field in Fig. 23. Window leaf 1 is arranged above it. A
metal section 44b that corresponds to section 44a is arranged on
s1ep 122, which is distinguished from section 44a basically only
in the fact that a leg 44a', i.e., the lower leg in Fig. 22, is
omitted and replaced by a bend 124. Between this bend and outer
seal 8 of solid field 84b, a relatively broad slot 125 is present
to provide ventilation to the rear and to allow water to drain.
St:ill, outer seal 8 is covered to a very large extent by section
44b.
In the embodiment of Fig. 24, two leaves 1 are connected to
st:ep 123. On the outside of the step, a section 44c that
corresponds to section 44b is arranged, which is distinguished
from section 44b by a larger width and also by the fact that two
circumferelltial outer seals 19 are arranged on section 44c.
A water collecting channel 126, from which water is removed
ei,ther at both ends or else via additional oblique holes 127, is
formed in step 123. In each case, holes 127 end in the space
behind sect:ion 44c. Removal of water to lower slot 125 is
ensured by corresponding holes 128 in the section rails.
CA 022289l6 l998-02-06

Fig. 25 shows the use of casing section lOd in a structural
gLazing, i.e., in a window leaf li, in which insulating glazing 3
i; arranged on leaf frame 2i in such a way that, when the window
i; open, t]he insulating glazing is fully visible, and when the
window is ,-losed, it is covered only in the area of its edge by
outer circumferential seal 81 that is arranged on section part
lOd'. An angular metal-holding section 129, which is used to
secure insulating glazing 3, is fastened to leaf frame 2i.
Fig. 2~5 again shows casing section lOd together with sealing
pieces 130, which seal the space behind outer section part lOd'
in the corners.
All sections 10-lOg and 94 can be produced, for example, in
that first and second section parts 10'-lOg' and 10''-lOg'' or
9~' and 94'' are made from metal by extrusion and then are merged
in a suitable device with elements 11 in such a way that the
latter extend with their longitudinal edges in each case into the
grooves that are formed between projections 20 and 21. Then,
w:ith a device that has rollers, outer projections 20 are
continuously deformed or bent in the direction toward inner
projection; 21 in such a way that elements 11 are snugly held in
p:Lace at their edges between projections 20 and 21.
Section parts 10' and 10'' are in each case produced as one
p:Lece with all their wall sections that are described below by
extrusion :Erom a suitable material, for example, metal, e.g.,
a]Luminum or an aluminum alloy. As a material for section parts
1()' and 10'', however, plastic materials, for example plastics
reinforced with fibers (e.g., glass fibers and/or carbon fibers),
CA 022289l6 l998-02-06
34
such as, for example, PVC, polyamide, etc., are suitable. When
section parts 10' and 10'' are produced from plastic, the latter
can also be produced in one piece with center section part 10'''.
In particular, when section parts 10', 10'', lOa', lOb',
loc', lOc'', lOd', lOd'', lOe', lOe'', lOf', lOf'', lOg', lOg'',
9~' and 94'' are made from metal, for example aluminum or an
a:Luminum alloy, separating elements 11 are made from a high-load,
preferably fiber-reinforced plastic.
Corner connectors (angle pieces) that are made of metal or
p:Lastic and that in each case connect together two adjoining
section pa:rts 10' of section 10 at corners and for this purpose
are fastened with their legs 131' in section parts 10' by, for
example, gluing, are referred to as 131 in Figures 1 and 28. It
goes without saying that these corner connectors 131 or similar
corner connectors can also be used in other sections lOa-lOg.
St:rength and anti-burglary protection are further enhanced by the
corner connectors.
The windows and French windows for buildings according to the
invention :in any case provide good protection against burglaries
since when the window or French window is closed, no gap that
would be easily accessible to burglary tools between the casing
and the leaf frame is formed.
In a s:implified view and in vertical section, Figure 29 shows
a window leaf that is generally referred to as lj and that is
designed, ior example, similar to window leaf 1, specifically
provided with a leaf frame 2j and with an insulating glazing that
is providecl in this leaf frame and is not shown in Figure 29.
CA 02228916 1998-02-06
By using a rotating-tilting fitting 132, whose basic
components are reproduced in Figure 30, window leaf lj is
arranged to pivot and tilt in casing 4j. The latter is only very
diagrammatically represented in Figure 29 and is formed from, for
example, casing section 10. It goes without saying that for
casing 4j, another of the above-mentioned casing sections can
also be used, for example casing section 10c or 10d.
Fitting 32, which is described in detail in EP 0 438 740 Al
and which is expressly referred to here, comprises, i.a., lower
rotating-and-tilting bearing 133, which is arranged in the area
of a lower corner between a horizontal and a vertical section of
leaf frame 2j on fold 5 that is located there, and an exhibition
device 134 with rod-shaped push-out arm 135.
Rotating-and-tilting bearing 133 consists basically of two
parts, namely of bearing part 136 that is designed as an angle
piece and that is to be fastened to-leaf frame 2j and bearing
part 137 that is to be fastened to casing 4j, i.e., to the lower
v~ertical part of this casing in the area of the window opening.
A projection 138, which is designed in the shape of a cylinder
and lies with its cylindrical axis parallel to the plane of
window leaf lj and perpendicular to the low, horizontal side of
lleaf frame 2j, is molded onto bearing part 136. On the lower
side, projection 138 has a bearing bore 139 that is designed as a
pocket borehole and is configured on the inside like a hollow
ball and that is widened like a funnel toward its lower open end.
Bearing part 137 is arranged with a pivot journal 140, which
is adjustably arranged on bearing part 137 and is designed
CA 02228916 1998-02-06
36
spherically at its free end, such that pivot journal 140 fits
into bearing bore 39. When fitting 132 is mounted, projection
138 is accommodated in a recess 141 in leaf frame 2j. Recess 141
is open on. the lower side of leaf frame 2j. Projection 138 is
completely accommodated in this recess, especially in such a way
that projection 138 does not project over the lower side of leaf
frame 2j. Bearing part 137 is fastened to the section of the
casing section that lies closer to the inside of the window,
i.e., for example when casing section 10 is used on section part
10'', when. casing section lOc is used on section part lOc'', and
when casing section lOd is used on section part lOd'',
specifically in each case on rail 29.
Exhibition device 134 further comprises a fastening angle
142, which. is hinged at a first end of push-out arm 135 with a
leg by means of a hinge pin 143. Fastening angle 142 can be
fastened t.o casing 4j with the other leg, for example, when
casing section 10, lOc or lOd is used in turn on section part
10'', lOc'' or lOd''.
With its second end that lies some distance from hinge pin
143, push-out arm 135 is held in place to pivot and to move in
the longit.udinal direction of the fold on a guideway, not shown,
that is arranged on an upper, horizontal portion of leaf frame 2j
in the area of fold 5.
Fittin.g 132 further comprises commonly used cuff rails 144
that are arranged in the area of fold 5 with connecting rod 145
that is gu.ided into the latter and that is moved in the
longitudinal direction in the known way when a window handle, not
37
shown, is actuated and are arranged on locking elements 146
which, when the fitting is closed, engage in locking pieces 147
that are arranged on leaf frame 2j to close window leaf lj.
When, for example, casing section 10, lOc or lOd is used, these
locking pieces 147 are in turn arranged on section part 10'',
lOc'' and 10'', specifically in each case on rail 29.
A cuff rail 144 with corresponding connecting rod 145 and
locking elements 146 is also arranged on the upper, horizontal
portion of leaf frame 2j, in such a way that when the fitting is
in the closed position as well as in the pivoting position, at
lleast one locking element 146 works together with a locking plate
148 on the lower side of push-out arm 135 and locks push-out arm
145 on leaf frame 2j to keep it from pivoting around its second
end, in such a way that in the pivoting position of the fitting,
window leaf lj can pivot around the common axis of pivot pin 140
and hinge pin 143.
In a view similar to Figure 30, Figure 31 shows a fitting
132a, which is distinguished from fitting 132 basically in that
instead of upper exhibition device 134, an upper bearing 133a is
provided, which consists of an angular bearing part 136a with
projection 138a. Projection 138a is completely accommodated in a
recess in the leaf frame. Bearing part 136a is fastened
analogously to bearing part 136, but in the upper corner. In
p:rojection 138a, a bearing pin 149 is arranged to be able to move
axially, specifically with the aid of a lever 150 that can be
actuated manually. Bearing 133a comprises a bearing part 137a,
which is mounted corresponding to bearing part 137 on the
CA 02228916 1998-02-06
38
respective casing section and which, instead of pivot journal
140, has a bearing bore 151, in which pivot journal 149 engages
when the window leaf is closed or when the window leaf is in the
pivoting position. By means of pivoting lever 150, the pivot
journal can be moved back in such a way that it is released from
bearing bore 151. This fitting 132a is also described in detail
in EP 0 438 740.
A characteristic of fitting 132 or 132a consists of the fact
that, i.a., especially lower rotating-and-tilting bearing 133
and/or upper bearing 133a are optically virtually invisible; in
particular, bearing part 136 and/or 136a is fastened invisibly in
the area of fold 5, and projection 138 or 138a is also
accommodated in recess 141 that is closed toward the inside of
the window leaf. Another characteristic of fitting 131 or 132a
consists of the fact that, i.a., closed window leaf lj lies with
its inner surface without a cover flush with the inside surface
of casing 4j.
The invention was described above in embodiments. It goes
without saying that changes as well as modifications are
possible. For example, projection 138 and pivot journal 140 can
also be reversed with respect to how they are attached to bearing
parts 136 and 137.
