As a rule, a free space, which is meant to facilitate the dislodging of the entire sliding element, including the rollers from the guide rail, exists between the sliding element and the bottom surface of the guide rail. During the normal operation, this free space can lead to an unintentional dislodging of the sliding element. In order to avoid this, anti-dislodging devices whose outer periphery facing the guide rail is only marginally distanced from the outer periphery of the guide rail, are provided on the sliding element or attachments of the same, so that the sliding element can be dislodged only after the removal of the anti-dislodging device. In such type of anti-dislodging devices, one faces problems during the overrunning of the guide rail clamps that support the guide rail - if they secure the guide rail at the bottom. USP 4 905 345 discloses a sliding element, which is guided by suspending on a guide rail, via brackets provided between the sliding element and the rollers. The guide rail is mounted in a U shaped supporting profile, which is open at the top and, like the supporting profile, consists of many sections. The sections of the supporting profile are supported in the joining region with angular clamps, whose horizontal side secures the bottom surface of the supporting profile. An anti-dislodging device for preventing unintentional dislodging of the sliding element is not provided. In known sliding elements suspended on brackets, anti-dislodging devices are provided, which are connected rigidly with the bracket, and with a part of their outer periphery, encompass or secure at the bottom with play, the outer periphery of the guide rail. In this regard, on the one hand an overrunning over of the guide rail clamp and on the other hand, a protection against dislodging must be ensured with the play required. The task of the invention is to suggest a solution, by means of which the anti- dislodging device, with marginal play - if required with no play whatsoever - in the moving of the sliding element, secures at the bottom, the guide rail as well as, while moving over of a guide rail clamp, the guide rail or the guide rail clamp, in such a way that the sliding element is locked against dislodging. According to this, the anti-dislodging device has a locking element, which is elastically adjustable against the guide rail and deflects while overrunning a guide rail clamp. As per the invention, the solution guarantees that the locking element is constantly in contact with the guide rail or with marginal play, operates on the guide rail, in such a way that a dislodging of the sliding element from the guide rail is not possible. On the other hand, because of the elastic adjustability of the locking element against the guide rail, there is the possibility that the locking element recedes if the guide rail clamp overruns, simultaneously the feature of protection against dislodging is still guaranteed. According to a particularly advantageous embodiment of the invention, the anti- dislodging device has a locking element, which projects from the clamp of the anti- dislodging device towards the guide rail, is spring-loaded, is adjustable against the guide rail and protects the sliding element against dislodging. While overrunning a guide rail seating, the aforesaid locking element deflects against the spring force in the clamp of the anti-dislodging device, by canceling the locking action of the locking element. For example, the locking element mounted in a pocket- shaped seating of the clamp of the anti-dislodging device is, as per the above mentioned features, located in the clamp in such a manner that during the sliding of the locking element along the guide rail, the locking element is locked against pushing back into the clamp, so that the protection against dislodging is guaranteed. On the other hand, while overrunning one of the guide rail clamps which secures the guide rail at the bottom, the locking element deflects in such a way against the force of a spring, by pushing into the clamp of the anti-dislodging device to the extent that the part of the guide rail clamp securing the guide rail at the bottom can be under-crossed, whereby the protection against dislodging is maintained. The anti-dislodging device can be in constant contact with the guide rail and the guide rail clamps. The locking element is advantageously mounted orthogonal to the direction of movement of the sliding element, swivelling about an axis moving in the direction of movement of the sliding element, in a pocket of the clamp of the anti-dislodging device, whereby the swivelling path of the locking element is limited to both swivelling directions by the seating surfaces of the locking element. The limiting of the swivelling path of the locking element during the overrunning of the guide rail in the position, which secures the sliding element against dislodging, is such that a catch of the locking element is located on the side - facing the supporting structure - of the guide rail outside the central longitudinal axis of the guide rail and adjacent to the outer periphery of the guide rail. On the other hand, the swivelling path of the locking element in the opposite direction is limited during the overrunning of a guide rail clamp, to such an extent that the catch of the locking element rests against the guide rail clamp, by leaving a sufficient play of the swivelling path. With the above-mentioned measures, in a sliding element of the type mentioned at the beginning, an anti-dislodging device is produced, which has a locking element that can be elastically reset. The reset facility of this locking element in the clamp of the anti- dislodging device is locked during the overrunning of the guide rail. The reset facility is released only on the overrunning of a guide rail clamp. The spring-loaded mounting of the locking element in the clamp of the anti-dislodging device is carried out preferably in such a manner that the clamp of the anti-dislodging device and the locking element have aligned bores, so that the locking element can be mounted in such a manner that it can swivel, by means of a pin passing through these aligned bores. In order to facilitate a smooth and quiet overrunning of the guide rail clamp by the locking element, angular stops are provided on the surface of the locking element facing the guide rail and/or the guide rail clamp, over which simultaneously the swivelling movement of the locking element against the clamp is initiated. Basically, the anti-dislodging device can be fastened to a bracket supporting the sliding element in any manner; however, it can be carried out advantageously by means of plug-in dowel pins provided on the anti-dislodging device, a dovetail joint or such like. The invention is illustrated below with the accompanying drawings, in detail by way of a possible embodiment. They show: Figure 1: A schematic sectional view of a glass panel. Figure 2: In comparison with Figure 1, an enlarged presentation of a vertical section through the glass panel according to Figure 1 during overrunning of the guide rail. Figure 3: An illustration corresponding to Figure 2, during the overrunning of a guide rail clamp. Figure 4: A partial side view as per Figure 2, by omitting the supporting structure. Figure 5: A side view of the locking element. Figure 6: A view of the locking element as seen from the supporting structure. Figure 7: A top view of the locking element as per Figure 6. Figure 7 & 9: Two views of the anti-dislodging devices with different attachment options to a bracket. In Figure 1 a glass panel is labeled as 1, which in the embodiment consists of two sliding elements 2 guided on a guide rail 5, which can be slided in the direction of arrow L. The sliding elements 2 are guided via brackets 3 and rollers 4 on the top surface 6 of the guide rail 5. The guide rail 5 is mounted by means of guide rail clamps 7 on a supporting structure 10 (see Figure 2 and 3). As shown in Figures 2 and 3, the brackets 3 are connected via spot retainers 8 on the sliding element. In the embodiment, a cover 9 which rests against the bracket 3, is provided between the bracket 3 and the sliding element 2. An anti-dislodging device 11 is connected to the bracket 3 or cover 9 by means of a screwed joint 29. A box-shaped recess is made - not shown precisely in the drawing - on the top surface of that part of the anti-dislodging device 11, which is identified as clamp 13, so that a locking element 12 can be mounted in this box-shaped recess. The locking element 12 is pre- tensioned in the direction of arrow B by means of a spring 14 shown in Figure 5 and during the overrunning of the guide rail 5, takes the position shown in Figure 2. Thereby, the catch 20 - which is adjacent to or resting against the outer periphery 22 of the guide rail 5 - of the locking element 12, is located at a distance, labelled as x, from the central longitudinal axis 21 of the guide rail 5 and locks the sliding element 2 against dislodging. A swivelling path of the locking element 12, which is identified by the direction of arrow B, is stopped at this position so that the locking element 12 cannot swivel further about its axis 17. While overrunning the guide rail clamp 7, the locking element 12 deflects, by swivelling about the axis 17 in a yet to be explained manner, in the direction of arrow C and can thus undercross that part of the guide rail clamp 7, which secures the guide rail 5 at the bottom, whereby at this point the catch 20 rests on that part of the guide rail clamp 7, which secures the guide rail at the bottom. The swivelling path in the direction of arrow C is so designed such that a sufficient pushing of the locking element 12 into the pocket (not shown) of the clamp 13 is possible. Figures 4 to 7 illustrate that the surface 25 of the locking element 12, which faces the guide rail 5 or the guide rail clamp 7, is provided with angular stops 26, which facilitate the swivelling action of the locking element 12 from the position shown in Figure 2, to the position shown in Figure 3, and a smooth overrunning of the guide rail clamp 7. The side view of the locking element 12 as per Figure 5 shows the mounting of a spring 14, whose leg 15 rests on the bottom of the pocket (not shown) of the clamp 13 and its leg 16 rests on the locking element. The through bore 24 in the locking element 12 is in alignment with corresponding bores 23 in the clamp 13, so that a pin, not shown, can be inserted through the bores 23 and 24. Further, figure 5 shows that the locking element 12 has seating surfaces 18 and 19, wherein the seating surface 19 together with a seating surface (not shown) of the pocket (not shown) of the clamp 13, forms the swivelling limit in the position shown in Figure 2, while the seating surface 18 forms the final swivelling limit in the position shown in Figure 3. The representation according to Figure 6 shows the locking element as seen from the supporting structure (direction of arrow A); the representation according to Figure 7 a top view of Figure 6. In the embodiment as per Figure 8, the clamp 13 of the anti-dislodging device 11, has dowel pins 27 which can be plugged-in in corresponding recesses of the bracket 3; in the embodiment as per Figure 9, the mounting is designed as dovetail joint 28.

SLIDING ELEMENT, COMPRISING AN ANTI REMOVAL DEVICE, WHICH IS
SUSPENDED, AND GUDIED ON A RUNNING TRACK BY MEANS OF ROLLER
CARRIERS
Description
The invention relates to a sliding element, comprising an anti removal device, which is
suspended, and guided on a running track by means of roller carriers, more
particularly the sliding element guided by means of rollers or gliding elements
suspended on the top surface of a guide rail - whereby the guide rail is connected to
the guide rail clamps on a supporting structure or such like, which secure the guide rail
at the bottom - with an anti-dislodging device provided at the bottom surface of the
guide rail on the sliding element or an attachments of the same.
As a rule, a free space, which is meant to facilitate the dislodging of the entire sliding
element, including the rollers from the guide rail, exists between the sliding element
and the bottom surface of the guide rail. During the normal operation, this free space
can lead to an unintentional dislodging of the sliding element. In order to avoid this,
anti-dislodging devices whose outer periphery facing the guide rail is only marginally
distanced from the outer periphery of the guide rail, are provided on the sliding
element or attachments of the same, so that the sliding element can be dislodged only
after the removal of the anti-dislodging device. In such type of anti-dislodging devices,
one faces problems during the overrunning of the guide rail clamps that support the
guide rail - if they secure the guide rail at the bottom.

USP 4 905 345 discloses a sliding element, which is guided by suspending on a guide
rail, via brackets provided between the sliding element and the rollers. The guide rail is
mounted in a U shaped supporting profile, which is open at the top and, like the
supporting profile, consists of many sections. The sections of the supporting profile are
supported in the joining region with angular clamps, whose horizontal side secures the
bottom surface of the supporting profile. An anti-dislodging device for preventing
unintentional dislodging of the sliding element is not provided.
In known sliding elements suspended on brackets, anti-dislodging devices are
provided, which are connected rigidly with the bracket, and with a part of their outer
periphery, encompass or secure at the bottom with play, the outer periphery of the
guide rail. In this regard, on the one hand an overrunning over of the guide rail clamp
and on the other hand, a protection against dislodging must be ensured with the play
required.
The task of the invention is to suggest a solution, by means of which the anti-
dislodging device, with marginal play - if required with no play whatsoever - in the
moving of the sliding element, secures at the bottom, the guide rail as well as, while
moving over of a guide rail clamp, the guide rail or the guide rail clamp, in such a way
that the sliding element is locked against dislodging.
According to this, the anti-dislodging device has a locking element, which is elastically
adjustable against the guide rail and deflects while overrunning a guide rail clamp. As
per the invention, the solution guarantees that the locking element is constantly in
contact with the guide rail or with marginal play, operates on the guide rail, in such a
way that a dislodging of the sliding element from the guide rail is not possible. On the

other hand, because of the elastic adjustability of the locking element against the guide
rail, there is the possibility that the locking element recedes if the guide rail clamp
overruns, simultaneously the feature of protection against dislodging is still
guaranteed.
According to a particularly advantageous embodiment of the invention, the anti-
dislodging device has a locking element, which projects from the clamp of the anti-
dislodging device towards the guide rail, is spring-loaded, is adjustable against the
guide rail and protects the sliding element against dislodging. While overrunning a
guide rail seating, the aforesaid locking element deflects against the spring force in the
clamp of the anti-dislodging device, by canceling the locking action of the locking
element. For example, the locking element mounted in a pocket- shaped seating of the
clamp of the anti-dislodging device is, as per the above mentioned features, located in
the clamp in such a manner that during the sliding of the locking element along the
guide rail, the locking element is locked against pushing back into the clamp, so that
the protection against dislodging is guaranteed. On the other hand, while overrunning
one of the guide rail clamps which secures the guide rail at the bottom, the locking
element deflects in such a way against the force of a spring, by pushing into the clamp
of the anti-dislodging device to the extent that the part of the guide rail clamp securing
the guide rail at the bottom can be under-crossed, whereby the protection against
dislodging is maintained. The anti-dislodging device can be in constant contact with
the guide rail and the guide rail clamps.
The locking element is advantageously mounted orthogonal to the direction of
movement of the sliding element, swivelling about an axis moving in the direction of

movement of the sliding element, in a pocket of the clamp of the anti-dislodging
device, whereby the swivelling path of the locking element is limited to both swivelling
directions by the seating surfaces of the locking element.
The limiting of the swivelling path of the locking element during the overrunning of the
guide rail in the position, which secures the sliding element against dislodging, is such
that a catch of the locking element is located on the side - facing the supporting
structure - of the guide rail outside the central longitudinal axis of the guide rail and
adjacent to the outer periphery of the guide rail. On the other hand, the swivelling path
of the locking element in the opposite direction is limited during the overrunning of a
guide rail clamp, to such an extent that the catch of the locking element rests against
the guide rail clamp, by leaving a sufficient play of the swivelling path.
With the above-mentioned measures, in a sliding element of the type mentioned at the
beginning, an anti-dislodging device is produced, which has a locking element that can
be elastically reset. The reset facility of this locking element in the clamp of the anti-
dislodging device is locked during the overrunning of the guide rail. The reset facility is
released only on the overrunning of a guide rail clamp.
The spring-loaded mounting of the locking element in the clamp of the anti-dislodging
device is carried out preferably in such a manner that the clamp of the anti-dislodging
device and the locking element have aligned bores, so that the locking element can be
mounted in such a manner that it can swivel, by means of a pin passing through these
aligned bores.

In order to facilitate a smooth and quiet overrunning of the guide rail clamp by the
locking element, angular stops are provided on the surface of the locking element
facing the guide rail and/or the guide rail clamp, over which simultaneously the
swivelling movement of the locking element against the clamp is initiated.
Basically, the anti-dislodging device can be fastened to a bracket supporting the sliding
element in any manner; however, it can be carried out advantageously by means of
plug-in dowel pins provided on the anti-dislodging device, a dovetail joint or such like.
The invention is illustrated below with the accompanying drawings, in detail by way of
a possible embodiment.
They show:
Figure 1: A schematic sectional view of a glass panel.

section through the glass panel according to Figure 1 during
overrunning of the guide rail.

Figure 7 & 9: Two views of the anti-dislodging devices with different attachment
options to a bracket.

In Figure 1 a glass panel is labeled as 1, which in the embodiment consists of two
sliding elements 2 guided on a guide rail 5, which can be slided in the direction of
arrow L. The sliding elements 2 are guided via brackets 3 and rollers 4 on the top
surface 6 of the guide rail 5. The guide rail 5 is mounted by means of guide rail clamps
7 on a supporting structure 10 (see Figure 2 and 3).
As shown in Figures 2 and 3, the brackets 3 are connected via spot retainers 8 on the
sliding element. In the embodiment, a cover 9 which rests against the bracket 3, is
provided between the bracket 3 and the sliding element 2. An anti-dislodging device 11
is connected to the bracket 3 or cover 9 by means of a screwed joint 29. A box-shaped
recess is made - not shown precisely in the drawing - on the top surface of that part of
the anti-dislodging device 11, which is identified as clamp 13, so that a locking element
12 can be mounted in this box-shaped recess. The locking element 12 is pre-
tensioned in the direction of arrow B by means of a spring 14 shown in Figure 5 and
during the overrunning of the guide rail 5, takes the position shown in Figure 2.
Thereby, the catch 20 - which is adjacent to or resting against the outer periphery 22
of the guide rail 5 - of the locking element 12, is located at a distance, labelled as x,
from the central longitudinal axis 21 of the guide rail 5 and locks the sliding element 2
against dislodging. A swivelling path of the locking element 12, which is identified by
the direction of arrow B, is stopped at this position so that the locking element 12
cannot swivel further about its axis 17.
While overrunning the guide rail clamp 7, the locking element 12 deflects, by swivelling
about the axis 17 in a yet to be explained manner, in the direction of arrow C and can
thus undercross that part of the guide rail clamp 7, which secures the guide rail 5 at

the bottom, whereby at this point the catch 20 rests on that part of the guide rail clamp
7, which secures the guide rail at the bottom. The swivelling path in the direction of
arrow C is so designed such that a sufficient pushing of the locking element 12 into the
pocket (not shown) of the clamp 13 is possible.
Figures 4 to 7 illustrate that the surface 25 of the locking element 12, which faces the
guide rail 5 or the guide rail clamp 7, is provided with angular stops 26, which facilitate
the swivelling action of the locking element 12 from the position shown in Figure 2, to
the position shown in Figure 3, and a smooth overrunning of the guide rail clamp 7.
The side view of the locking element 12 as per Figure 5 shows the mounting of a
spring 14, whose leg 15 rests on the bottom of the pocket (not shown) of the clamp 13
and its leg 16 rests on the locking element. The through bore 24 in the locking element
12 is in alignment with corresponding bores 23 in the clamp 13, so that a pin, not
shown, can be inserted through the bores 23 and 24. Further, figure 5 shows that the
locking element 12 has seating surfaces 18 and 19, wherein the seating surface 19
together with a seating surface (not shown) of the pocket (not shown) of the clamp 13,
forms the swivelling limit in the position shown in Figure 2, while the seating surface 18
forms the final swivelling limit in the position shown in Figure 3.
The representation according to Figure 6 shows the locking element as seen from the
supporting structure (direction of arrow A); the representation according to Figure 7 a
top view of Figure 6.

In the embodiment as per Figure 8, the clamp 13 of the anti-dislodging device 11, has
dowel pins 27 which can be plugged-in in corresponding recesses of the bracket 3; in
the embodiment as per Figure 9, the mounting is designed as dovetail joint 28.
