Background of the invention
[0001] For the sake of safety of being on a balcony, terrace, or similar space, there is
a railing structure at the front edge of such a space, such as a balcony. A railing
structure equipped with cover plates also acts as a wind screen and possibly also
as a visibility screen.
[0002] The railing structure may be fastened to a side of a balcony slab, i.e. in practice
to a front edge of the balcony slab. A second basic way that is also utilised in the
present invention is to have the railing structure on the balcony slab. The location
of the railing structure is determined by the fastening point of the horizontal lower
profile of the railing structure.
[0003] The structure according to the invention is suitable for mounting both on a support
such as a slab and to a side, or edge, of a support such as a slab, that is, to the
outer edge of a balcony slab.
[0004] For reasons relating to architecture and costs, a railing structure that does not
use dedicated vertical posts between the lower profile and upper profile, that is,
the handrail, has become more and more popular. This structural principle sets new
challenges to the stability and rigidity of the railing structure and thus to the
safe usage.
[0005] Postless glazed railing systems have a groove in the top surface of the lower profile
for the horizontal lower edge of the glazing, and similarly on top of the glazing
in the lower surface of the top rail, that is, in the lower surface of the so-called
handrail there is a groove for the horizontal upper edge of the glazing.
[0006] An important detail in railing structures without vertical posts is how the glazing
structure, that is, the cover plate elements, are in relation to the horizontal rail
/ lower profile under the glazing and horizontal top rail, which may be called the
handrail of the railing, on top of the glazing,
[0007] A fastening method is known where the glass is glued by its horizontal bottom edge
to a glazing groove of the lower profile and glued by its horizontal upper edge to
the glazing groove in the lower surface of the handrail.
[0008] A fastening method is also known where the structure, as concerns the lower profile,
is such that there are, in a recess at the front edge of a balcony slab, for example,
large and robust tightening structures between the slab and the lower profile, by
means of which the inner wall defining the glazing groove of the lower profile is
pushed, along the entire wall, towards the glazing in glazing groove. Finally, the
recess and the large and robust fastening structures at the front edge of the balcony
slab are covered by the concrete pouring to be added.
[0009] In the known postless systems the load is received by a railing plate supported by
its lower end, only.
[0010] The known solutions are either deficient as to their effect, or cumbersome, large,
or heavy either structurally or as regards their implementation.

rail, which is pushed obliquely from the above by a bolt. Publication
WO2015145477 discloses a separate wedge in the horizontal rail, which is tightened by a vertical
bolt. In these known solutions, the coupling of the tightening protrusion to the horizontal
rail is inadequate, which in turn makes the fastening of the glass pane elements worse,
which in turn weakens the operation of the railing structure, that is, the glazed
railing system. Publication

Detailed description of the invention
[0016] An installed entire glazed railing system may be mostly seen in Figures 3, 4 and
8, the details being best seen in Figures 1, 2 and 7.
[0017] With reference to the figures, the target of application is a glazed railing system
GA positioned in an embodiment to a balcony 1 with a balcony slab 10, which is a concrete
slab 10 of suitable strength, either an element concrete slab or one cast in place.
[0018] The glazed railing system GA comprises lower profile DR on top of the balcony slab,
such as a bottom rail DR, that is, a bottom rail DR.
[0019] The structure according to the invention is suitable for mounting/fixing both on
a support such as a slab and to a side, or edge, of a support such as a slab, that
is, to the outer edge of a balcony slab.
[0020] In addition, the glazed railing system GA comprises a top rail UR, that is, an upper
profile 31 such as a top rail 31, which is the handrail of the glazed railing system,
against which a user may rest his hand.
[0021] Referring to Figure 8, for example, the glazed railing system GA additionally comprises
a glazing structure G consisting of one or more glazing elements G1-G3 and being a
cover plate structure protecting the balcony. Each glazing element G1 of the glazing
structure is a so-called railing glass or plate.
[0022] The lower profile DR, just like the upper profile UR, too, may be an aluminium strip,
such as profile strip, made by extrusion.
[0023] This, then, is a glazed railing system GA which comprises a horizontal bottom rail
DR and a handrail HR as a horizontal top rail, as well as a glazing groove DRG, that
is, a glass groove in the bottom rail DR and a glazing groove URG, that is, glass
groove in the handrail URG, and a glazing structure G comprising one or more glazing
elements G1-G3 and being located by means of the glazing grooves DRG, URG between
the bottom rail DR and handrail UR.
[0024] Referring to Figures 1-2, the glazed railing arrangement additionally comprises a
fastening structure FS for fixing the glazing structure G to the bottom rail and top
rail. Both the bottom rail DR and the top rail UR have their own fastening arrangements
FS for the glazing G.
[0025] Referring to Figure 8, in particular, when examining even a single horizontal rail
such as the bottom rail DR or top rail UR, in an embodiment there is a plurality of
fastening structures FS along the reach of the horizontal rail such as DR, UR and
they are at a distance from each other. This way, a point-form strong fastening force
is created between the glazing G, G1-G3 and the horizontal rail such as DR, UR. The
fastening structures FS, FS1-FS5 for fastening the glazing G are in such a manner,
for example, that there are 5 fastening arrangements along the 300 cm long bottom
rail DR, whereby with an even distribution the distance in between the fastening points
FS is approximately 60 cm, if the edge-most fastening arrangements FS1, FS5 are near
the ends of the bottom rail DR. The distance in between the locations of the fastening
structures FS, FS1-FS5 may also be more or less than the aforementioned 60 cm in the
example.
[0026] As relates to the fastening structures FS, it is noted that the fastening structure
comprises in the bottom rail DR and/or handrail DR in a wall W bordering the glazing
grooved DRG, URG, a flexible tightening protrusion PR which may be distanced from
the wall W by bending. In addition, the tightening structure FS comprises in the bottom
rail DR and/or bottom rail, that is, handrail UR, a chamber such as a threaded chamber
THRN and a pushing member PD, rotatable in relation to the threaded chamber THRN and
having a threaded outside, in other words, provided with an external thread THRO.
The pushing member PD has in an embodiment a threaded surface, so equipped with an
external thread THRO.
[0027] In an embodiment, both the bottom rail DR and the handrail UR have, in the wall W
bordering the glazing groove DRG, URG, a plurality of integral tightening protrusions
PR, which may be distanced from the wall W by bending.
[0028] Even though the chamber THRN was in the above and will below be treated as a threaded
chamber and the pushing member PD as a pushing member with a threaded surface, the
invention is to be understood more broadly, so the principle of threads is not a must,
albeit found good. The chamber THRN guides the pushing member PD so that the integral
tightening protrusion PR on the wall W of the glass groove DRG, URG in the horizontal
rail DR, UR is caused into a transverse tightening movement towards the glass groove
and glazing or other similar cover plate structure. An integral tightening protrusion
PR in the rail UR, DR means that the tightening protrusion PR is of the same integral
material piece with the rail and not an added part, and the tightening protrusion
PR is so created that in an extruded rail, for example, vertical parallel thin grooves
are made to form the flexible tightening protrusion PR. The transverse width of the
tightening protrusion PR is consequently determined by the distance between the aforementioned
parallel grooves.
[0029] Hence, it may be noted that when examining both the glazed railing system and the
horizontal rail, that as the fastening structure FS for fastening the glazing structure
the horizontal rail such as DR comprises, in the wall W of the horizontal rail, surrounding
the glazing groove, a tightening protrusion PR that may be distanced from the wall
in question, and additionally the chamber THRN which is the guide of the pushing member
PD placeable in the chamber, said chamber THRN being arranged to guide the pushing
element PD placeable in the chamber to push said tightening protrusion PD from the
side towards the glazing groove DRG. The pushing member PD may be seen as a part of
the horizontal rail or a part that may be added to it.
[0030] The threaded chamber THRN comprises an internal thread THRI. The external thread
THRO comprised by the pushing member PD and the internal thread THRI comprised by
the threaded chamber THRN together establish a threaded transmission which is between
the pushing member PD and the threaded chamber in the horizontal rail DR.
[0031] As the pushing member PD proceeds in the threaded chamber THRN, it is arranged to
push said tightening protrusion PR towards the side surface of the glazing structure
G in the glazing groove, on the edge area thereof. On the bottom rail DR side, the
edge area of the side surface of the glazing is in the groove DRG for the lowest 25-30
mm of the side area of the glazing, for example.
[0032] The examples of the figures show that there is a seal S between the groove such as
URG and the glass G, so in the figure the tightening protrusion PR moves against the
seal S when the pushing member PD such as a bolt is rotated forward in the threaded
chamber THRN, whereby the pushing member is able to push the back surface BS of the
tightening protrusion PR. It is noted that the in the area below the threaded chamber
THRN and the bolt-type pushing member PD, the back surface BS of the tightening protrusion
extends obliquely in relation to the longitudinal direction of the threaded chamber
THRN and pushing member PD, because in such a case the pushing member PD pushes the
tightening member PD the more powerfully towards the seal S and glazing groove URG
the further the pushing member PD is rotated. The inclined back surface BS of the
tightening protrusion PR extends in the bottom rail below the threaded chamber (in
the top rail UR, that is, the handrail, on top of the threaded chamber), in other
words from the viewpoint of the threaded chamber THRN, on the exit side of the pushing
member PD. This achieves the fact that by means of the same threaded chamber and the
pushing member PD with a threaded surface settable in it, an adjustable tightening
is obtained, because as the pushing member PD is rotated further still, the integral
tightening protrusion PR is wedged closer and closer to the seal S and glazing G.
The seal S is not obligatory, that is, the tightening protrusion PR may also be in
direct contract with the side surface of the glazing element or similar cover plate
element at the lower part and/or upper part of the side surface.
[0033] In the figure, the seal S is a U-type seal trough that achieves sealing on both sides
and fast installability. The seal S has protrusions SPR towards the glazing G to improve
contact. In the bottom rail DR under the seal S at the very bottom of the groove there
may be a support piece SP, as shown in Figure 1.
[0034] It is observed that in an embodiment the glazed railing system is such that in addition
to the tightening protrusion PR which is on the wall W surrounding the glazing groove
such as DRG and which may be distanced in relation to the wall W, also the threaded
chamber THRN for the pushing member PD with the threaded surface is on this wall surrounding
the glazing groove.
[0035] The horizontal rail such as the bottom rail DR is an integral structural part, extruded,
for example, so the tightening protrusion PR is an integral area/spot/part with the
rest of the horizontal rail DR, which also applies to the chamber THRN on the wall
W of the horizontal rail DR, such as the threaded chamber machined into the horizontal
rail. This way, these structures help make the fastening of the glazing G to the horizontal
rail DR fixed, that is, non-floating, and such that it better conveys forces from
the glazing to the horizontal rail, which is also helped by the fact that the gripping
from the tightening protrusion PR to the glazing is at the side surface of the glazing,
by its lower edge (bottom rail DR) and/or the upper edge (top rail DR, that is, handrail).
The structure may be similar in the top rail, that is, handrail UR. A postless, stabile
glazed railing system is achieved.
[0036] In a postless glazed railing system the rail glasses G, G1, G3 are able to receive
the required support forces and forward them, because the fastening arrangement FS,
FS1-FS5 of the rail glasses G1-G3 to the bottom rail and handrail is of the type disclosed
in the above.
[0037] Referring to Figure 3 in particular and also to 4 and 6, it is observed that by means
of the disclosed structure the situation is reached where a force from the balcony
side, so as though from the inside, is divided in addition to the direction A also
to directions B by means of the glazing element G1 and the foil F therein, whereby
impact energy is transferred from the glass pane element to the handrail of the rail
and to the adjacent glass pane element/elements.
[0038] Referring in particular to Figure 4, the matter is next discussed in relation to
the sides a, b, and c of the railing structure, of which side b is the middlemost,
so usually the longest side, and sides a and c are the edge sides. This is related
to the transfer of a sideward lateral force of two adjacent separate sides to the
other side, whereby a force in the direction of the horizontal profiles DR, UR is
received by the glass.
[0039] This way the horizontal forces of the side a in the direction of side b are received
by the handrail and the bottom rail UR of side b are immovably fastened to each other.
[0040] Correspondingly, the forces in the direction of the horizontal rails DR, UR of the
sides a and/or c of side b are arranged to be received by the ensemble of the side
a and/or a and b, that is, by the interconnected ensemble of the handrail UR and glasses
G, G1-G3 and bottom rail, which also has the fastening arrangements FS, FS1-FS5 in
the bottom rail (correspondingly in the top rail).
[0041] It may be noted that if an impact is received from the inside on side b, the force
is conveyed from the glass G, G1-G3 to the lower profile DR which is fastened to the
slab 10, and the force is also conveyed to the handrail DR which is fastened to the
wall by fastenings WF. Because the glasses G1-G3 are fastened by fastening arrangements
FS, FS1-FS5 by pressing to the horizontal rails DR, UR, in an impact situation the
glass to which the impact is targeted bends outward, whereby the horizontal rails
such as the handrail UR tends downward or upwards, but because the glasses are fastened
to the horizontal rails, they remain to support the movement of the handrail UR so
that it does not detach from the glasses and so that the glass that received the impact
will not become detached from the rail.
[0042] When an impact from the inside is received at side a in the direction of the arrow
C1, the bottom rail DR receives the force from the glass because the bottom rail DR
is fastened to the slab 10.
[0043] In Figure 4 because the glasses G1-G3 of side b so the front side so the longest
side are properly pressed to the lower and top rails DR, UR, they make sturdier the
support of its side c so much that the rail can take an impact from the direction
C1.
[0044] In such a case, the handrail UR, UR1, UR2 is a structure firm enough for a balcony
glazing to be fastened on top of it.
[0045] To make the railing structure more rigid, the wall fastenings WF of the extremes
of the handrail according to Figure 4 are used by bolts, for example.
[0046] The discloses structure is suitable for both straight rails, as well as L-shaped
and U-shaped ones.
[0047] In the following, the structure of Figures 9-10 is examined. A postless glazed railing
system comprises a handrail 901, bottom rail 902 and glass pane elements G91-G93 as
well as fasteners A11-A14, B21-B24, A31-A34, that is the fastening structures (as
in the above FS, FS1-FS5) with which the glass pane elements G91-G93 are fastened
in a fixed, so non-floating, manner to the handrail 901 and the bottom rail 902. In
an embodiment, the glass pane elements G91-G93 are such that they have a laminated
structure of 4 mm + 4 mm glasses and a middle foil (such as foil F above). The glazed
railing arrangement works so that if, for example, an impact is received in the middle
of the glass pane element G92 (by a person on the balcony, for example), the fasteners
B21-B24 (their structure as FS, FS1-FS5 in the above) cause the laminated glass pane
element G92 bends as in Figure 10 and tries to pull the handrail 901 and bottom rail
902 towards each other. This is possible because the glass pane elements G91-G93 are
fastened to the handrail 901 and the bottom rail 902 (by fastening structures of the
type of the fastener structures FS, FS1-FS1, so with fasteners A11-A14, B21-B24, A31-A34)
so that the glass pane element cannot detach from them in any situation. During an
impact incident (force FFF, Figure 12) the glass pane elements G91 and G93 support
the handrail 901 and bottom rail 902 in their original position. Therefore the glass
pane elements G91 and G93, in a way, from invisible posts or the handrail 901 and
bottom rail 902. Because the glass pane element G92 is permanently locked between
the rails 901 and 902, the middle foil inside the laminated glass pane element G922
(such as foil F in the above) presents a significant added value for the durability
of the whole, because the glass pane elements cannot detach from the handrail (top
rail) 901 or the bottom rail 902, and by means of the foil the impact force FFF is
transferred to the handrail and bottom rail as well as to adjacent glasses G91, G93.
With this structure, it is possible to establish a much sturdier structure than the
conventional floating glass pane elements, or alternatively more economical untempered
glass can be used, and, above all, an entirely postless railing structure. The inventive
structure thus transforms the orthogonal force FFF into a vertical force FU, FD, which
is received by the middle foil of the laminated glass pane element G92, from which
it is conveyed by fixed fasteners B21-B24 to the handrail 901 and bottom rail 902,
and the force is cancelled by the neighbouring glass pane elements G91, G93.
[0048] Referring to Figures 11-12, it is possible that the neighbouring glass pane element
may be on the adjacent transverse side, that is, on a transverse face side (such as
GG, I) in relation to the long side (such as H). Figure 12 shows schematically a glazed
railing structure from the top, that is, a railing structure having sides GG, H and
I, of which side H is the middlemost so the long side, and the shorter sides GG and
I are face sides. By means of the fastening structure (FS, A11-A14, B21-B24, A31-A34)described
in the above, the side of a balcony railing forms a plate-like structural entity (bottom
rail - fastening - glass pane element - fastening - handrail), by means of which the
forces it receives and distributes to neighbouring sides are much better than in the
conventional methods and allow the establishing of a postless but durable glazed railing.
[0049] In Figure 11, the handrail 111 is tied to the bottom rail 112 by means of the glass
pane element G11 and fasteners A111-A114 (structures as FS, FS1-FS5). Fasteners A111-A114
keep the glass pane element G11 firmly in place. In such a case, a horizontal force
on the handrail 1, for example, is transferred to the bottom rail 112 by means of
the glass pane elements and provides a counter-force to the force. The structure may
be used to implement a postless railing system of the minimum of two sides. Referring
to Figure 12, the force FFF to the balcony side H from the inside (so the balcony
side) is distributed on sides GG and I, which support the side H so that the plate-like
structure of the sides GG and I helps receive the forces in question.
[0050] The railing structure of both Figures 9-10 and 11-12 is fastened to the wall by the
handrail 901, 111.
[0051] In an embodiment, the chamber such as the threaded chamber THRN for the pushing member
PD is substantially vertical, the direction being comparable as the transverse direction
to the longitudinal direction of the horizontal rail. The installation work is then
easy to carry out, and the adjustability of the tightening is easy to implement because
the pushing member PD taking a pushing contact to the backside BS of the tightening
protrusion is able to push the tightening protrusion to the transverse direction,
that is, to the transverse horizontal direction in the figures towards the seal S
and glazing G, so the bottom part of the side surface of the glazing in the bottom
rail, and top part of the side surface of the glazing in the top tail, that is, handrail.
[0052] By means of some embodiments, the usability and characteristics of the invention
may be further improved.
[0053] In an embodiment, the threaded chamber THRN for the pushing member PD is substantially
parallel to the depth direction, so vertical direction, of the glazing groove such
as DRG. It is additionally so that this threaded chamber for the pushing member is
substantially parallel to the longitudinal direction of the tightening protrusion.
[0054] The threaded chamber THRN has a diameter of 8 mm, for example, so it is meant for
a pushing member PD with a diameter of 8 mm and having a threaded surface. Obviously,
the diameter may be another, for example 6 mm.
[0055] The threaded chamber THRN for the inner pushing member extends at least partly in
parallel with the tightening protrusion. In addition, in an embodiment it is so that
the tightening protrusion PR is substantially parallel to the depth direction, that
is, the vertical direction of the glazing groove DRG, because in such a case the protrusion
is in a good place and more easily caused into a tightening motion towards the seal
S and glazing G.
[0056] The passing through length of the threaded chamber THRN is 5-20 mm, for example,
because this results in a good support for the pushing member PD with a threaded surface,
with which the tightening protrusion PR at the edge of the glazing groove DRG is pushed
from the side.
[0057] The tightening protrusion PR is an arm bent by the pushing member PD, the structure
of which is such that the tightening protrusion PR comprises a free end T and at the
opposite edge of the tightening protrusion a base BA of the tightening protrusion.
In an embodiment, the free end T of the tightening protrusion PR is further from the
bottom of the glazing groove than the base of the tightening protrusion, so the free
end T of the tightening protrusion is on the side where the glazing G, G1-G3 enters
the groove, so the tightening protrusion PR makes contact with the side surface of
the glass in an area from a distance of the horizontal edge of the glass, but close
to the horizontal edge.
[0058] It is observed that in an embodiment the tightening protrusion PR extends at least
partly in parallel with the glazing groove DRG, in which case the position of the
tightening protrusion PR is good and the desired direction of movement is more easily
obtainable for it towards the seal S and glazing G, which, as mentioned, are in the
groove DRG.
[0059] Regarding the significance of the method of implementation of the tightening arrangements
FS, it may be said that the tightening arrangements of the type referred to form a
fixed, non-floating fastening for the glazing structure G, G1, G2 with both the bottom
rail DR and the handrail UR. Such a fixed, non-floating fastening is thus arranged
to shift a load directed at the glazing structure G to both the bottom rail DR and
through it to the installation platform 10, such as the balcony slab, of the glazed
railing arrangement, and additionally also to the handrail UR and through it and both
its ends to the vertical edges of the installation site, such as walls.
[0060] By means of the disclosed structures the use of untempered laminated glass becomes
possible (no need for expensive and heavier tempered glass) even when the fastening
of the glazing G to the horizontal rails DR, UR is fixed, so non-floating.
[0061] With reference to Figure 6, the glazing structure, that is, its single glazing element
in practise, comprises, as mentioned, two untempered glazing parts GLA, GLB laminated
to each other through the foil F. Each glazing element, such as G1 and G2, is then
a laminated glazing element formed of two glazing parts GLA, GLB, placed against each
other, and a middle foil F. The middle foil F has the aforementioned role of transferring
the loading sidewards. However, it is such a case at some sites or in some countries
that it is desirable or necessary to use glazing elements that have a glass pane element
laminated with the aid of the foil F, but the other of its glasses is then tempered
and the other one untempered.
[0062] Relating to the work during installation time becoming easier, the depth of the glazing
groove DRG in the bottom rail DR is at least 28 mm and the transverse width of the
glazing groove DRG is at most 1.5 mm, such as 0.2 mm - 0.8 mm, wider that the thickness
of the glazing structure. The thickness of the laminated glazing structure may be,
for example, 4 mm + 4 mm, and the width of the glazing groove slightly more.
[0063] The glazing groove such as DRG is deep enough but narrow so that the glass G, G1-G3
stays up for the installation time even without temporary supports, but it is possible
that on the bottom rail DR side the tightening arrangements FS, PD, PR of the glass
are tightened even before the handrail UR is installed.
[0064] The installation of a glazed railing system GA starts so that at first the bottom
rail DR is fixed to the support such as balcony slab 10, then the glazing elements
G1-G3 of the glazing structure G are lifted in their place in the groove DRG of the
top surface of the bottom rail DR.
[0065] Next the top rail UR, that is, handrail is installed in its place and each tightening
arrangement FS in both the bottom rail DR and handrail/top rail UR is tightened by
rotating the pushing members PD in the chambers THRN so far that the tightening protrusion
PR by its base BA is wedged by bending more tightly towards the glass G, in Figure
1 through the seal S.
[0066] According to the applicant's observations, a suitable installation order is: first
the bottom rail DR, next glazing elements/cover plate elements G1-G3, next top rail,
that is, handrail UR, next the fastening of the handrail UR by fasteners WF to the
walls, and finally the tightening of the elements G1-G3 to the bottom rail DR and
top rail UR by means of the inventive fastening arrangements FS (PR, THRN, PD).
[0067] The tightening arrangements such as FS for the top rail UR are similar to those for
the bottom rail DR, and due to the opposite position of the top rail, the mouth of
the chamber THRN is at the bottom surface of the rail and the chamber THRN is pointed
upward.
[0068] Instead of the upward direction, the chamber THRN may also be horizontal, for example,
both in the bottom rail DR and top rail UR.
[0069] The invention is also suitable as a partition of business premises or another space.
[0070] In addition to or instead of an entire glazed railing system GA, the invention may
be examined as a horizontal rail. In other words, it is a horizontal rail such a bottom
rail DR or handrail UR, that is, top rail UR for a glazed railing system. The horizontal
rail such as DR, UR comprises a glazing groove such as DRG, URG for the glazing structure
G.
[0071] As was disclosed for the entire glazed railing system GA, as the fastening structure
FS for fastening the glazing structure G to the horizontal rail DR, UR, the horizontal
rail comprises in a horizontal rail wall W surrounding the glazing groove DRG, URG
a tightening protrusion PR that may distanced in relation to the wall W, and additionally
a chamber THRN such as a threaded chamber, in particular. Additionally is needed a
pushing member that is movable, such as rotatable, in relation to the chamber. The
pushing member PD may in an embodiment be provided with a threaded surface, such as
a bolt-type or threading tap type pushing member, which is arranged, guided by the
chamber THRN, to push said tightening protrusion PR from the side, that is, from the
direction of the edge wall W towards the glazing groove DRG, that is, also towards
the seal S and glazing G. What is important is the tightening protrusion PR and in
its vicinity the chamber THRN, because they make it possible to set the pushing member
PD, moving it in relation to the chamber THRN and the tightening protrusion PR and
affecting by the pushing member PD to butt the tightening protrusion PR towards the
glazing groove and the glazing therein.
[0072] Referring to Figure 7, it is noted that on the front surface of the tightening protrusion
PR, so the surface towards the glazing surface DRG, the tightening protrusion comprises
a bulge H1, which both improves the fastening of the glasses G1/G3 to the groove,
but also as in Figure 7 positions the seal S in its place when the seal has a similar
notch or another space. It is observed that the outer wall WW surrounding the glazing
groove DRG in the horizontal rail DR comprises a bulge H2, which also positions the
seal S and improves fastening to the glass.
[0073] A person skilled in the art will find it obvious that, as technology advances, the
basic idea of the invention may be implemented in many different ways. The invention
and its embodiments are thus not restricted to the above-described examples but may
vary within the scope of the claims.
