Description

The present invention relates to a cleaning apparatus for a system including a horizontally displaceable member for closing an opening and a guide rail for horizontally guiding the displaceable member when displaced in a horizontal sliding direction. In this case, the cleaning device has a fastening means for fastening the cleaning device to the component and a cleaning element for cleaning the guide rail. The present invention further relates to a displaceable member for closing an opening.

Such slidable components for closing openings and such systems with displaceable component and guide rail are known per se. They are used, for example, in furniture construction, as room or front doors or as a room divider. Slidable components are in particular sliding doors or sash windows. The displaceable component is usually mounted in or on the guide rail and is thus by this arrangement to the rail-guided component. By the guide rail of the possible displacement of the component is predetermined. The guide rail advantageously facilitates the displacement of the component.

In the course of using such a system, there is an increasing contamination of the guide rail, for example with dust. As a result, the movement of the component can be impeded or hindered. This is especially true for for ground-based systems in which the guide rail is arranged on or in the ground and the component is placed on the guide rail.

From the DE 20 2007 006 128 U1 a sliding element is known, which is movable over a carriage, on which a roller is mounted, on a guide rail. It should be kept as a cleaning element on the carriage or on a sliding body a scraper, which contacts the running surface of the guide rail for cleaning.

From the DE 296 03 912 U1 a sliding gate is known, which is arcuately displaceable and consists of a plurality of lamellar members. The sliding gate has a displaceable component that is connected to at least one scraper as a cleaning element. The scraper rests with a scraper edge on a mounting rail, are hung on the support rollers, which are connected to the slats. When moving the sliding gate, the wiper edge brushes away sediment deposited on top of the support rail.

From the WO 2009/074251 is a wall, door or window element known, which is supported by rollers on a lower support or floor rail movable. The element comprises a cleaning member which, during a process of the element, cleans the area of a running surface of the rail on which the roller passes during the movement of the element.

The CA 2282795 A1 describes a sliding door, which is guided by means of guides at the top and bottom for horizontal displacement on rails. On the lower guide cleaning elements are attached both at its front and at its rear end, which serve to clean the rail when moving the door. The cleaning elements are attached to an upper side of the guide and extend obliquely from the upper side in the direction of the rail. At their lower ends they have recesses into which the lower rail engages. When moving the sliding door, the front cleaning element viewed in the direction of displacement scrapes along the rail and cleans it.

From the US 4,208,755 is also known a sliding door having at its lower end a cleaning element for cleaning a rail in which the sliding door is guided.

It is the object of the present invention to enable a comfortable displacement of a displaceable component by means of a guide rail.

This object is achieved according to the technical teaching of claim 1 or claim 12.

According to the invention, the fastening means comprises a spring steel, which is angled at a bend line, so that an angled portion is present, which is in an assembled state of the cleaning device in which it is attached to the component between the guide rail and one of the guide rail adjacent end face of the Component extends. In this case, the cleaning element is arranged on the angled portion. Further, an absorber for preventing transmission of sound to the device is provided. The sound occurs in the mounting state of the cleaning device in which it is attached to the component, when moving the device. The component according to the invention contains the cleaning device according to the invention.

Due to the present invention, it is advantageously possible to fix the cleaning device at a suitable location on the displaceable component. The cleaning device should be arranged so that the cleaning element can exert a cleaning effect on the guide rail. Advantageously, the guide rail can therefore be easily cleaned by means of the cleaning element during the sliding operation. Dirt or dust on the guide rail can be easily removed during normal use of the component. Separate cleaning operations are advantageously not required. The cleaning device according to the invention is advantageously designed so that it can be retrofitted in a simple manner for already installed components. Particularly advantageously, the invention can be used in floor-guided systems in which the component is horizontally displaceable in or on the guide rail. In particular, the displaceable component represents a movable closure for an opening. The component is in particular a sliding door, in which the cleaning device according to the invention can be used particularly advantageously. Especially in a floor-mounted system, such a sliding door for moving may have rotatably mounted rollers which rest on the guide rail and are rolled over this when moving. Due to the present invention, it is possible to largely Prevent a variety of dust and / or dirt particles are pressed into the bearing surfaces of the rollers in the course of use, remain stuck in it and hinder the shifting process. Even a possibly required replacement of dirty rollers can be advantageously prevented or at least greatly delayed in time. As a result, repair costs and costs can be avoided. For efficient cleaning of the guide rail, the fastening means of the cleaning device according to the invention is connected for the sake of simplicity with its cleaning element. Particularly advantageously, the fastening means is designed so that it allows a particularly secure and stable fastening of the cleaning device to the component. For example, the shape and / or dimension of the attachment means may be adapted to the shape and / or dimension of that location of the device to which it is attachable to the device. In particular, a groove may be present at a suitable location on the component, into which the fastening means can be inserted. The fastener may in this case z. B. be designed plug-shaped. The attachment of the fastening means to the device can be done for example by means of terminals. Alternatively or additionally, the fastening means may be designed such that it can be screwed onto the component. The fastening means may for this purpose have one or more bores through which suitable screws for stable fastening can be passed. The cleaning element is advantageously designed so that it fits snugly against the guide rail to be cleaned. Particularly advantageously, the cleaning element may comprise a soft, flat material, for example a pillow, a felt material or a fabric. In an assembled state of the cleaning device, in which it is fastened to the component, the cleaning element arranged on the section protrudes, in particular, over a lower edge of the component adjacent to the guide rail in order to be able to clean the guide rail particularly well in this way. The section extends into a gap between the component and the guide rail. In this case, an existing between the component and the guide rail usually anyway distance can be advantageously used for attaching the section. Advantageously, this ensures a particularly low installation height. Particularly advantageously, the cleaning device is designed for cleaning a support surface of the guide rail. On this support surface, the device, in particular by means of their roles, for moving. The use of the spring steel for the fastener advantageously ensures a particularly stable and durable cleaning device. The bending of the fastener on the bend line allows a particularly space-saving attachment of the cleaning device on the device and at the same time a reliable cleaning of the guide rail. The bend line can be introduced in a cost effective and simple manner in the spring steel.

The absorber ensures a particularly quiet movement of the component. The sound can arise in particular by a grinding of the cleaning element on the guide rail to be cleaned. In this case, the sound represents a grinding noise. By means of the absorber, a transfer of the sound from the cleaning device to the component can advantageously be avoided. The sound can not penetrate into the component. Depending on the structure of the building element, this could actually cause an amplification of the sound penetrated in the device at a penetration of the sound in the device. This could especially with common components, especially sliding doors with hollow sections, z. As aluminum, be the case. This is prevented by this advantageous embodiment of the invention. Particularly advantageously, the absorber itself can absorb sound.

The absorber is arranged so that it is in the mounting state of the cleaning device between the fastening means and the component. This prevents the transmission of sound to the component in a particularly simple and efficient manner. The absorber may in particular represent a spacer means for generating a distance between at least a part of the fastening means and the component in the mounting state of the cleaning device. A direct contact between at least a part of the fastening means and the component during the displacement of the component can thus be advantageously avoided. The sound could be transmitted to the component particularly well via such a contact. Particularly simply, the absorber can be attached directly to the attachment means.

Furthermore, the fastening means is designed such that the cleaning element on a side facing the guide rail side of the section and the
Absorber is attached to one of the end face of the component facing side of the section. This embodiment of the invention ensures a particularly efficient cleaning of the guide rail and at the same time a low-noise displacement of the component in a particularly simple manner. Should the portion of the fastener move when moving the device in the direction of the end face of the device, it is advantageously prevented by the absorber that a direct contact between the fastener and the device takes place, carried by the transmission of sound to the device particularly well could.

Preferably, the fastening means is angled at an obtuse angle. This advantageously ensures a simple height adjustment of the cleaning device to the guide rail. Furthermore, the cleaning element in the mounting state of the cleaning device can invest particularly well and closely to the guide rail.

Particularly advantageously, the absorber extends substantially over the entire length of the end face of the component facing side of the section. As a result, the transmission of sound to the component can be prevented in a particularly simple and efficient manner.

The absorber preferably has a foam material. Such an absorber is particularly inexpensive to use and prevents transmission of sound in a particularly simple manner. Particularly advantageous is a flexible foam. A thickness of the foam material of about 2 mm is advantageous. This is a low installation height and ensures perfect functionality. Advantageously, the foam material has a deformability of about 3/10 mm - 4/10 mm in normal operation.

Particularly preferably, the fastening means on an adhesive for adhering the cleaning device to the device. The adhesive is designed as an absorber. With the adhesive, the cleaning device can advantageously be attached to the component in a particularly simple and reliable manner. Further, by such an adhesive, two functions can be performed at one time, namely, attaching the cleaning device to the device and preventing the transmission of sound to the device.

Particularly preferably, the adhesive has a double-sided adhesive tape. The double-sided adhesive tape is arranged with one of its adhesive sides on the fastening means. The other adhesive side of the double-sided adhesive tape is used to stick the cleaning device to the component. The double-sided adhesive tape is inexpensive and the cleaning device can be attached to the component in a particularly simple manner. At the same time, the adhesive tape advantageously produces a sound-like decoupling between the cleaning device and the component in a simple manner. The double-sided adhesive tape is advantageously a foamed double-sided adhesive tape which in particular has a thickness of 2/10 mm - 3/10 mm. Such an adhesive tape fulfills the function of the absorber in a simple and efficient manner.

In a further advantageous embodiment, the fastening means are flat and the cleaning device elongated. In this way, the cleaning device can be particularly easy to attach to the device. In particular, for the sake of simplicity, it is possible to stably fix the cleaning device to a front end face of the component viewed in the sliding direction. A designed in this way cleaning device can be particularly easily retrofitted to an already installed device. In this embodiment of the invention, the fastening means thus has a flat shape. This means in particular that the thickness of the fastening means is less than its width. Advantageously, its width is more than three times as large as its thickness. Furthermore, the cleaning device has an overall elongated shape. This means in particular that its length is greater than its width. Advantageously, its length is more than three times as large as its width.

Particularly advantageously, the cleaning device has a damping element for damping impact forces, which act in a direction opposite to the sliding direction. These impact forces act on the damping element and are in the assembled state of the cleaning device in reduced strength, d. H. damped, transferred to the component. The damping element can thus advantageously serve as a damping stop. With this stop can be advantageously realized the damping and reducing vibrations that act on closing the opening and when hitting the device against the opening in the sliding direction limiting boundary, such as a wall element on the device. The damping element has a particularly advantageous effect when the cleaning device is fastened to a front end face of the component viewed in the sliding direction.

Preferably, the cleaning device comprises a force means for exerting a force that is designed such that it exerts the force in the mounting state of the cleaning device in which it is attached to the displaceable component in the direction of the guide rail. As a result, it is advantageously achieved that the cleaning element is pressed against the guide rail to be cleaned. This ensures a particularly good cleaning performance. Particularly advantageously, the spring steel of the fastening means is implicitly designed as a force means by a suitable bending at the bend line. This is the case in particular when the fastening means is fastened to the component in such a way that the cleaning element is pressed against the guide rail. The spring elasticity of the spring steel ensures a simple, resistance-free displacement of the component. Advantageously, the section is angled at an obtuse angle. As a result, the force acting in the direction of the guide rail can be generated in a particularly simple manner.

In a particularly preferred embodiment of the invention, the cleaning element on a felt material. Such a felt can advantageously adapt particularly well to a contour of the guide rail. He is also very robust. The felt material is most advantageously a polyester felt material blended with latex.

Preferably, the cleaning element is detachably arranged. As a result, the cleaning element is easily removable from the cleaning device. The cleaning element can then be cleaned or replaced, for example, comfortably. For example For example, a cleaning member having a brush may be replaced with a cleaning member having a scraper or vice versa. The cleaning element is advantageously releasably connected to the fastening means.

Particularly advantageously, the shape of an end region of the cleaning element is adapted to the shape of the guide rail to be cleaned. This makes it particularly easy to clean the guide rail. The shape of the end region of the cleaning element is matched to the shape of the guide rail. In particular, the two forms can be complementary to each other. For example, if the guide rail to be cleaned has a bearing surface with a convex shape, a particularly good cleaning performance can be achieved if the cleaning element has a concave shape adapted to the convex shape of the guide rail.

Advantageously, the fastening means may comprise a plastic injection-molded part, which is designed for receiving in the displaceable component. The plastic injection molding is inexpensive to produce and allows a particularly stable attachment of the cleaning device to the device. Furthermore, such a plastic injection molded part in the assembled state of the cleaning device ensures a sound decoupling between the cleaning device and the component. For example, the fastening means can be designed so that the plastic injection-molded part engages when installed in the component in a receptacle of the component. Advantageously, the plastic injection molding also allows easy retrofitting of the cleaning device in the device.

The component according to the invention particularly preferably has two cleaning devices. In this case, a cleaning device is a cleaning device according to the invention for cleaning the guide rail and the other cleaning device designed to clean a rotatably mounted roller of the movable component and arranged. With such an embodiment of the invention, a particularly good cleaning can be ensured. It can further be ensured that the component is also comfortably displaceable over time.

The component according to the invention preferably contains two cleaning devices according to the invention for cleaning the guide rail. In this case, the one cleaning device, viewed in the sliding direction, before and the other cleaning device, viewed in the sliding direction, arranged behind the rotatably mounted roller of the displaceable component. By this arrangement of two cleaning devices, a particularly good cleaning of the guide rail can be achieved. This ensures a durable comfortable and quiet moving of the device. In particular, the rotatably mounted roller can be particularly well protected from dust and dirt. Such dust and dirt can settle even with closed by the device opening, for example by Luftverwirbelungen especially on the guide rail and hinder the displacement during movement of the device. The inventive arrangement of the two cleaning devices impurities, possibly even after prolonged non-displacement of the device can be reliably removed before the role is moved when moving over the guide rail. When moving the component in both sliding directions thus a previous cleaning of the guide rail is guaranteed.

In the following, unless otherwise stated, the same reference numerals are used for the same or equivalent elements.

Fig. 1 shows a sectional view of a section of a door leaf 2 of a sliding door 4 with a first cleaning device 6 and a second cleaning device 8. The sliding door 4 is a displaceable member for closing an opening. In the present embodiment, the sliding door 4 serves as a room door, with a Closes the room. The opening is formed by a recess in a room wall. The sliding door 4 is supported, inter alia, on a guide rail 10, which is glued to the floor of the room. For this purpose, the guide rail 10 on a support surface 12, rest on the rotatably mounted in the sliding door 4 wheels. In the embodiment according to Fig. 1 such a roller 14 is shown. The support surface 12 has a convex curvature, which cooperates with a concave curvature of a tread 16 of the rollers. This is in Fig. 2 shown in more detail. The sliding door 4 and the guide rail 10 are here components of a floor-mounted locking system for rail-guided closing of an opening, ie in the present embodiment, the room opening. The sliding door 4 is for closing the room opening along the guide rail 10 in a sliding direction S and for opening the closed by means of the sliding door 4 room opening in the sliding direction S opposite sliding direction S 'displaced.

The cleaning device 6 has a fastening means 18. With this fastening means 18, it is at one, in the sliding direction S considered, front End face 20 of the sliding door 4 in the lower, the guide rail 10 adjacent end portion attached. The fastening means 18 is advantageously provided here with an adhesive 22, with which the fastening means 18 is glued to the end face 20. However, it is also possible to use a different type of attachment. For example, the fastening means 18 could be fastened to the sliding door 4 by means of screws. For this purpose, if necessary, two bores spaced apart from one another in the longitudinal direction of the fastening means 18 would be introduced into the fastening means 18, by means of which the screws can be screwed into the sliding door 4. As a fastening means 18, a spring steel is used here. The spring steel is bent or angled on a horizontally extending crease line 24 in the direction of a lower, the guide rail 10 adjacent end face 26 of the sliding door 4, that it extends between the end face 26 and the guide rail 10 on. This part of the spring steel, which extends starting from the bending line 24 down further, is referred to here as an intermediate piece 28. At the lower end of the intermediate piece 28, a brush-shaped scraper 30 is arranged, which constitutes a cleaning element for cleaning the support surface 12 of the guide rail 10. The scraper 30 may advantageously also be a scraper-shaped scraper. The scraper 30 is advantageously designed so that it fits tightly against the support surface 12 or snugly fits against the support surface 12. This ensures a particularly good cleaning of the support surface 12. The configuration of the intermediate piece 28 generates in the assembled state of the cleaning device 6, in which it is attached to the sliding door 4, a force on the scraper 30, which acts vertically downwards, in the direction of the support surface 12 , As a result, the scraper 30 is pressed onto the support surface 12. The intermediate piece 28 thus acts in this embodiment as a force means for exerting a force in the direction of the guide rail 10 to be cleaned. Since the intermediate piece 28 is obtained here by bending or bending of the spring steel, the intermediate piece 28 could also be considered as part of the fastening means 18. Advantageously, the scraper 30 is detachably connected to the intermediate piece 28 here. As a result, the scraper 30 can be easily replaced with another scraper.

The fastening means 18 contains on its, viewed in the sliding direction S, front end face a damping element 32. The damping element 32 serves to dampen impact forces acting in the sliding direction S opposite sliding direction S 'on the damping element 32. The damping element 32 absorbs these impact forces at least partially, ie it reduces or mitigates the impact forces. By the shock forces generated shocks on the sliding door 4 can thus be advantageously kept low. Such impact forces can occur in particular when the sliding door 4 is closed, specifically when the sliding door 4 abuts against the wall of the room delimiting the opening in the sliding direction S. The damping element 32 is in this sense a stop element, which has a suitable damping property.

The fastening means 18 has a flat shape in the present embodiment. This means in particular that its thickness, d. H. its extension in sliding direction S, is smaller than its width. Here its width is more than five times as large as its thickness. The small thickness of the fastening means 18 offers the advantage that in the closed state of the sliding door 4, only a small gap between the wall of the room and the end face 20 of the sliding door 4 occurs. The cleaning device 6 has an overall elongated shape here. This means in particular that the length of the cleaning device 6 is greater than its width. In the present embodiment, the length of the cleaning device 6 is more than five times as large as its width. This advantageously ensures a stable attachment of the cleaning device 6 to the sliding door 4. At the same time can be configured in a particularly simple manner, the fastening means 18 in the form of the intermediate piece 28 as a force means for exerting force in the direction of the guide rail 10. The present embodiment of the cleaning device 6 allows their attachment to the sliding door 4 in a simple manner. Particularly advantageously, this fastening can also be carried out with the sliding door 4 already installed. It is thus a completely unproblematic retrofitting of existing sliding doors with the cleaning device 6 possible. Furthermore, the cleaning device 6 can be mounted largely independently of the type of construction of the sliding door, in particular of the type of caster suspension. Furthermore, the assembly of the cleaning device 6 is easy to carry out. The cleaning device 6 is inexpensive to produce and also has a very low weight. A removal of the cleaning device 6 of the sliding door 4 is possible in a simple manner.

The cleaning device 8 is mounted in the present embodiment inside the sliding door 4 in the region of a bracket 34 for the roller 14. As a fastening means of the cleaning device 8 is here a plastic injection molded part 36, which, viewed in the sliding direction S, arranged laterally in front of the roller 14 and with the holder 34 is connected. The cleaning device 8 further comprises a brush 38, which constitutes a cleaning element for cleaning the roller 14. The brush 38 is attached to the plastic injection-molded part 36 and arranged so that it is in contact with the running surface 16 of the roller 14. The brush 38 is here advantageously detachably connected to the plastic injection molded part 36. The brush 38 can thus be removed in a simple manner and, for example, exchanged for another cleaning element, for example a scraper.

Fig. 2 shows a plan view of the viewed in the sliding direction, front end face 20 of the section of the door panel 2 according to the embodiment according to Fig. 1 , In the lower end region of the end face 20, the cleaning device 6 is glued by means of its fastening means 18. On the fastening means 18, the damping element 32 is arranged. Starting from the bending line 24, the intermediate piece 28 extends obliquely backwards, ie into the sheet plane. The scraper 30 attached to the lower end of the intermediate piece 28 has a lower end portion 40. The shape of this end portion 40 is configured concave here. Thus, the shape of the end portion 40 is adapted to the convex shape of the support surface 12 of the guide rail 10. This advantageously ensures a particularly good cleaning action of the scraper 30. Side next to the support surface 12, grooves 42 and 44 are present in the guide rail 10, which run parallel and along the support surface 12. The grooves 42, 44 allow a particularly easy rolling of the rollers of the sliding door 4th

When moving the sliding door 4, the scraper 30 slides over the support surface 12 and cleans them of dirt, such as dust. The dirt can be picked up by the scraper 30 or displaced by it into the grooves 42, 44 of the guide rail 10 provided laterally next to the support surface 12. The support surface 12 is thus substantially free of dirt. The following roller 14 of the sliding door 4 can then largely unrolled on the support surface 12 roll. The grooves 42, 44 may advantageously be conveniently cleaned from time to time, for example by means of a suction device. In addition to the cleaning device 6, the cleaning device 8 cleans when moving the sliding door 4, the running surface 16 of the roller 14. For this purpose, the brush 38 brushes when rotating the roller 14 along the tread 16th

Fig. 3 shows a perspective view of a sliding door 4, which has a cleaning device 46. Shown is the arranged in the sliding door 4 holder 34 for rotatable bearings of the impeller 14. The cleaning device 46 is mounted in the interior of the holder 34 by means of its fastening means so that it, viewed in the sliding direction S, is arranged in front of the bottom protruding from the holder 34 roller 14. The cleaning device 46 here has a scraper 48 as a cleaning element for cleaning the support surface 12 of the guide rail 10. The scraper 48 also protrudes down from the holder 34 and is in operative contact with the support surface 12. The scraper 48 is made of a substantially hard material, so that it scrapes when moving the sliding door 4 along the support surface 12. The lower, with the support surface 12 in contact end portion of the scraper 48 has a shape that is adapted to the shape of the support surface 12. In particular, the two forms complement each other. In the present embodiment, the shape of the end portion of the scraper 48 is concave and the shape of the support surface 12 is convex. The operation of the cleaning device 46 otherwise corresponds to the operation of the cleaning device 6 described above.

Fig. 4 shows a schematic representation of a side view of an embodiment of a cleaning device 50 according to the invention, which is constructed substantially the same as the previously described cleaning device 6. The same or equivalent elements of the cleaning device 50 are therefore provided with the same reference numerals as in the cleaning device 6. The cleaning device 50th includes the fastener 18, which is made in the present case of spring steel. At the crease line 24, the elongated spring steel is kinked, so that a lower portion of the fastening means 18, the intermediate piece 28, is angled at an obtuse angle with respect to an upper main part 52 of the fastening means 18. On a downwardly facing side 54 of the intermediate piece 28 of the scraper 30 is mounted here. The scraper 30 represents a cleaning element for cleaning a bearing surface of a guide rail for guiding a sliding door during displacement. The scraper 30 is in the present embodiment, in contrast to the scraper 30 according to Fig. 1 , attached exclusively to the downwardly facing side 54 of the intermediate piece 28. The scraper 30 is in the present embodiment, a felt, in particular a polyester felt, which is mixed with latex. Such a scraper is advantageously particularly flexible and tolerates different heights of the guide rail. Furthermore, it can adapt particularly well to the contour of the guide rail and is still very robust.

On an upwardly facing side 56 of the intermediate piece 28, an absorber 58 for preventing transmission of sound is mounted on the sliding door, which occurs in the mounting state of the cleaning device 50 in which it is attached to the sliding door, when sliding the sliding door. In the assembled state of the cleaning device 50, the scraper 30 is looped over the guide rail, in which the sliding door is guided. As a result, grinding noise, ie sound, arise that are audible to a user and disturbing it noticeably. The grinding noises are especially disturbing when they are transferred to the sliding door. Especially in the sliding door existing hollow sections can further enhance the transmitted from the cleaning device 50 on the sliding grinding noises. Through the use of the absorber 58, a transmission of disturbing sound is advantageously largely avoided. The absorber 58 extends substantially the entire length of the side 56 of the intermediate piece 28 and abuts with its left end at a contact line 60 to the adhesive 22 at. The adhesive 22 is here a double-sided adhesive tape, which is arranged with one of its adhesive sides on the fastening means 18 and which serves with its other adhesive side for sticking the cleaning device 50 to the sliding door. The adhesive 22 extends to the crease line 24. The adhesive 22 is here also designed as an absorber for preventing transmission of sound to the sliding door, which in the assembled state of the cleaning device 50, in which it is attached to the sliding door, when moving the Component occurs. The adhesive 22 is here advantageously a foamed double-sided adhesive tape, which in particular has a thickness of 2/10 mm - 3/10 mm. Such an adhesive tape fulfills the function of the absorber in a simple and efficient manner and ensures a sound-like decoupling between the cleaning device 50 and the sliding door 4. When manufacturing the cleaning device 50, the adhesive 22 is attached to the fastening means 18 in front of the absorber 58. This can be ensured in a simple manner that the double-sided adhesive tape is actually applied up to the bending line 24. It is thus ensured that the side of the main part 52, on which the adhesive is applied, is completely covered. A direct contact of the sliding door by the main part 52 is thus not possible even if the absorber 58 would be pressed slightly too strong in its attachment to the spacer 28 at its left edge. On the side facing away from the adhesive 22 side of the main part 52 of the fastening means 18, the damping element 32 is attached.
