Description

[0001] One aspect of the invention relates to a household refrigeration appliance with a storage compartment for food and a rail that can be attached to a wall.

[0002] From EP 1 926 956 B1, a household refrigerating appliance is known in which very short, block-like coupling pieces are arranged on the side walls of an inner container. These coupling pieces are attached to the inside of the inner container's side walls by mechanical couplings. These coupling pieces are designed to accommodate other, separate components of the household refrigerating appliance, such as a shelf or a drawer.

[0003] Furthermore, a household refrigeration appliance is known from US patent 2003 / 0173882 A1. Rail elements are attached to an inner container by mechanical couplings. The rail in US patent 2003 / 0173882 A1 has an integrated spring element on a vertical wall. This allows only mechanical position adjustment and connection with an accessory that can then be additionally attached to this rail.

[0004] Here too, these mechanical fastenings are simply plug-in connections or interlocking connections created by sliding the aforementioned components together. All respective elements provided in the prior art for coupling between a side wall of the inner container and a coupling piece are inherently rigid and fixed in position.

[0005] The object of the present invention is to provide a household refrigeration appliance and a method in which, or with which, a separate rail can be attached simply yet in a mechanically highly stable and positionally accurate manner in a food storage compartment of the household refrigeration appliance.

[0006] This problem is solved by a household refrigeration appliance according to claim 1.

[0007] One aspect of the invention relates to a household refrigerator with a storage compartment for food. The household refrigerator has at least one horizontally arranged wall. Furthermore, the household refrigerator has at least one rail separate from this wall. The rail is arranged on the top side of the wall. The rail has an integrated snap-in element. The wall has a receptacle for the snap-in element in which the snap-in element is engaged.

[0008] With a household refrigerator like this, mounting and attaching a rail to the top of such a wall is simple, yet secure and firmly fixed. The rail sits directly on top of the refrigerator, viewed from the height of the appliance. The mechanical connection is very simple, yet robust and stable. It can withstand the necessary mounting forces as well as subsequent holding and load-bearing forces without the rail wobbling, moving unintentionally, or coming loose from its fixed position. A snap-fit ​​connection is particularly advantageous in this regard, as it is easy to create and release, and therefore reversibly connect and disconnect multiple times. Furthermore, a snap-fit ​​connection is highly functional and permanently effective. Snapping the connection from above is particularly easy and offers excellent accessibility for the user.

[0009] Such a rail, mounted prominently on a wall, can then withstand corresponding mechanical loads and, for example, serve to hold another food container, which is then attached to this rail and can be moved relative to it. Even if this container has a considerable weight, the rail can easily absorb the forces involved when the container is placed on and moved, without itself undergoing any undesirable movements relative to the wall.

[0010] The rail is therefore functionally and in accordance with its intended purpose, in particular a support rail for receiving a plate-shaped part, such as a shelf or for receiving a food receiving tray or food receiving container.

[0011] In one embodiment, the snap-in element is elastically spring-mounted on the rail. This makes coupling and decoupling the snap connection easy. Furthermore, the snapped state is easily detectable, particularly by the snap-in element clicking into its receptacle. This can be perceived both haptically and audibly. This ensures that the rail can always be positioned securely on the wall, and the final position can be reached quickly and precisely.

[0012] In one embodiment, the snap element is formed on a vertical side wall of the rail, in particular integrated and thus formed and arranged integrally with it. This makes it easy to achieve a laterally cantilevered extension while still ensuring the snap element is stably integrated with a base element of the rail, in this case, the vertical side wall of the base element. This allows for a very precise and consistently uniform spring movement up and down.

[0013] In one embodiment, the snap element is arranged laterally, and in particular cantilevered freely, projecting from the rail perpendicular to a longitudinal axis of the rail. This results in a highly exposed position and a highly customizable extension, making it easily accessible and thus readily operable by a user, particularly for releasing the snap connection. This lateral projection, oriented perpendicular to the longitudinal axis, advantageously facilitates vertical snapping and thus downward engagement with the snap element receptacle. Combined with its position on a vertical side wall of the rail, this allows for the elastic movement and spring action of the snap element in the vertical direction to be implemented very easily and without obstruction.In this context, this lateral position is particularly advantageous for accessibility, and furthermore, this snap element does not obstruct the longitudinal axis forwards or backwards, so that the rail is not undesirably extended in the longitudinal direction.

[0014] In one embodiment, the snap element has an engagement part that engages in the snap element receptacle when snapped into place. Furthermore, the snap element has a roof part that differs from the engagement part. The roof part adjoins the engagement part from above, in particular directly. In one embodiment, the roof part extends, at least partially, beyond the dimensions of the engagement part when viewed horizontally. "Horizontal" in this context refers specifically to a plane in which the longitudinal axis of the rail also extends, or parallel to this plane and in a direction perpendicular to it. This creates a horizontal plane defined by the width and depth of the household refrigeration appliance. In particular, this roof part extends beyond the dimensions of the engagement part in this width and / or depth direction of the household refrigeration appliance.This design mechanically stabilizes the engagement element, while the roof section's geometry also acts as a height stop for the snap-in element. This prevents the snap-in element from entering the snap-in receptacle too deeply. The snapped end position of the snap-in element within the receptacle is thus advantageously defined and achieved, and can also be perceived haptically. This is the case when the user manually engages the snap-in element by directly grasping it. Finally, this geometry of the snap-in element also simplifies the release of the snapped state. Contacting the snap-in element with the roof section is simplified, allowing the snapped state to be achieved more quickly and without potentially damaging the snap connection.For example, by grasping the roof section and simply pulling up the snap element on the roof section.

[0015] In one embodiment, the roof section therefore forms an upper stop in the vertical direction, which, when the snap element is engaged, is located outside the snap element receptacle. In particular, in this engaged state, the roof section covers the snap element receptacle from above, at least partially. This also ensures, in one example, that no additional media can penetrate the snap element receptacle, or at least reduces such penetration.

[0016] In one embodiment, the rail, viewed along its longitudinal axis, has a first coupling element at its rear end. In the assembled final state of the rail, this first coupling element is coupled to a first coupling element receptacle. This first coupling element receptacle is formed on a second wall of the domestic refrigeration appliance. The second wall is not, in particular, in the same plane as the first wall. The two planes of the first and second walls can be oriented parallel to each other. However, the two planes are specifically arranged at an angle to each other. For example, the first wall can be a horizontal floor wall. The second wall can be a vertically oriented wall. The second wall can, for example, be a rear wall. It can thus define the rear boundary of the receiving space.

[0017] Preferably, the first coupling element engages in the direction of this longitudinal axis of the rail and thus, in particular, axially into this first coupling element receptacle. Viewed in the direction of this longitudinal axis, the first coupling element and the first coupling element receptacle overlap in the coupled state.

[0018] In one embodiment, the first coupling element is oriented with a cantilevered rearward in the axial direction, i.e., along the longitudinal axis of the rail. The first coupling element thus preferably projects rearward beyond a beam-like base body or a base element of the rail. This functionally and spatially enables a further specific mechanical, and in particular exclusively mechanical, coupling of the rail to a second wall that differs from the first. This facilitates the mechanical fastening and positioning of the rail on multiple different walls.

[0019] In one embodiment, the connection between the first coupling element and the first coupling element receptacle is a plug connection. Specifically, it is exclusively a plug connection; no snap-fit ​​or similar mechanism is used. This results in a simple coupling principle that nevertheless contributes to the overall mechanical stability and positional fixation of the rail to walls.

[0020] In one embodiment, the rail, viewed along its longitudinal axis, particularly on a second side wall, has a second coupling element which engages in a second coupling element receptacle when the rail is assembled. The second coupling element receptacle is formed, in particular, on a third wall of the domestic refrigeration appliance. The third wall is, in particular, a wall different from the horizontal first wall and the preferably existing second wall. It is also preferably spanned in a different plane than the first horizontal wall or the second wall. In particular, this coupling between the second coupling element and the second coupling element receptacle is formed perpendicular to the longitudinal axis of the rail.This means that the second coupling element and the second coupling element receptacle are arranged overlapping each other perpendicular to the longitudinal axis of the rail when this coupling connection is formed. This further improves the positioning of the rail in the domestic refrigeration appliance. This additional coupling connection with the second coupling element and the second coupling element receptacle is also a purely mechanical coupling connection. It, too, is non-destructive, reversibly detachable, and reconstructible.

[0021] In one embodiment, the rail can be directly connected to different walls of the domestic refrigerator at three different local points, each mechanically, and in particular only mechanically, coupling. This achieves particularly advantageous positional fixation. Specifically, the coupling between the second coupling element and the second coupling element receptacle is a plug connection. It is, in particular, exclusively and thus only a plug connection. The advantages achievable thereby have already been explained in relation to the advantageous embodiment concerning the first coupling element and the first coupling element receptacle. In particular, it is provided that the plug connection direction, in which the first coupling element and the first coupling element receptacle are configured as a plug connection in their preferred embodiment, is perpendicular to the plug connection direction of the second coupling element into the second coupling element receptacle.In particular, the insertion direction between the first coupling element and the first coupling element receptacle can be oriented in the depth direction of the domestic refrigeration appliance and / or thus, in particular, parallel or coaxial to the longitudinal axis of the rail. Preferably, the second insertion direction between the second coupling element and the second coupling element receptacle is oriented in the width direction of the domestic refrigeration appliance.

[0022] In one embodiment, the snap-in element receptacle is a trough-like recess. In particular, it is a blind-hole-like depression. This means that the snap-in element receptacle is designed without any openings and is therefore free of openings. Specifically, the first coupling element receptacle is trough-like. It can be a blind-hole-like depression. Here, too, a depression without openings is formed. The same can be the case with the second coupling element receptacle in one embodiment.

[0023] In one embodiment, the rail is formed in one piece. It can therefore also be manufactured in one piece. It is made of plastic, for example, it can be an injection-molded component. In its assembled final state, the rail is attached to one or more walls of the domestic refrigeration appliance only by one or more of the aforementioned coupling connections. No further fastening devices, in particular separate fasteners such as screws or the like, are provided.

[0024] In one embodiment, the rail is a guide rail for a component of the household refrigeration appliance. In particular, the component can be, for example, a plate-like part, such as a shelf or the like. However, the component can also be container-like, such as a tray or a box. In this context, the component can be a food container or a food holding container.

[0025] In one embodiment, the rail has at least one integrated first roller receptacle into which a separate guide roller can be inserted, in particular, which can be inserted at least partially recessed therein. This guide roller allows the aforementioned separate device component to be guided more effectively relative to the rail when the rail is mounted on it. This guide roller is thus mechanically stable thanks to this roller receptacle, yet still moves as freely as possible relative to the rail, in particular being rotatable.

[0026] In one embodiment, a wall is a wall of the inner container, for example, the bottom wall. However, the wall can also be a wall separate from the inner container, arranged in the receiving space and covering at least part of a wall of the inner container.

[0027] It is also possible that a wall, designed for the attachment of the separate rail, is permanently fixed within the household refrigerator. However, it is also possible that such a wall can be removed from the interior space. This can be done non-destructively and reversibly. Such a wall could, for example, be a horizontal panel, such as a shelf. A lid of a food storage system could also be such a wall, on which at least one rail could be mounted and attached from above, extending vertically along the interior of the refrigerator.

[0028] A wall can have at least two layers. It can have an outer layer. This outer layer can face the recording space. It can be the layer on which the rail rests. The outer layer can be made of plastic.

[0029] Another aspect of the invention relates to a method for mounting a rail on a wall of a household refrigeration appliance. The household refrigeration appliance is designed, in particular, according to the aspect mentioned above or an advantageous embodiment thereof. Specifically, the rail is snapped into the snap-in receptacle with the snap element, so that the rail is attached to the first wall from above by means of the snap connection. This is, in particular, a connection that can be released without causing damage.

[0030] Preferably, during assembly, the rail is first inserted into the second coupling element receptacle along with the second coupling element. This creates a preliminary coupling, which in particular forms a pivot bearing around which the rail is then moved into its final position. In this position, it snaps into place with the snap element in the snap element receptacle and simultaneously couples the first coupling element into the first coupling element receptacle. This allows the rail to be detachably fastened, preferably, to three different walls, especially those with different orientations. This is achieved particularly without the walls having any openings.

[0031] In particular, and also more generally, the snapped end position of the snap element in the snap element receptacle is supported by the rail bearing against the third wall. This third wall provides a counter-bearing for the engagement of the snap element in the snap element receptacle. Specifically, the snap element is pressed into the snap element receptacle by the third wall in the direction perpendicular to the longitudinal axis A and in the width direction. This presses a surface area of ​​the snap element, especially the engagement part, facing away from the third wall, against a surface area on the inside of the snap element receptacle facing the third wall. This achieves the locked and snapped state.During assembly, when the rail at its front end reaches the third wall, particularly through pivoting, the snap element, which until then has been elastically pressed upwards by resting on the horizontal wall, especially the floor wall, automatically snaps downwards from this pre-tensioned state into the snap element receptacle. It is then precisely aligned in the snap element receptacle, at least in the aforementioned surface areas.

[0032] Exemplary embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Fig. 1 a schematic, perspective view of an embodiment of a household refrigeration appliance according to the invention; Fig. 2 a perspective view of an embodiment of a rail according to the invention; Fig. 3 a rear view of the rail according to Fig. 2 ; Fig. 4 a perspective view of subcomponents of the household refrigeration appliance according to Fig. 1 with several walls, on which the rail according Fig. 2 and Fig. 3 can be attached; Fig. 5 a representation of the arrangement according to Fig. 4 and in addition, according to the rail Fig. 2 in the still decoupled state; Fig. 6 a top view of the representation according to Fig. 5 ; Fig. 7 a perspective view of the arrangement according to Fig. 4 and Fig. 5 with, however, the final mounted state of the rail on the walls; Fig. 8 an enlarged view of the design in Fig. 7 ; Fig. 9 a perspective sectional view through the arrangement in Fig.8 at the point of the snap connection; and Fig. 10 the view in Fig. 9 in a sub-area in the cutting plane.

[0033] In the figures, identical or functionally equivalent elements are assigned the same reference lines.

[0034] In Fig. 1 Figure 1 shows a simplified perspective view of an exemplary embodiment of a household refrigeration appliance (1). The household refrigeration appliance (1) can be a refrigerator, a freezer, or a combination refrigerator-freezer. It is designed for the storage and preservation of food.

[0035] The household refrigerating appliance (1) has a housing (2). A separate inner container (3) is housed within the housing (2). The inner container (3) encloses at least one storage compartment (4), which is designed to hold food. The inner container (3) is preferably manufactured by deep drawing. It is made of plastic. The storage compartment (4) can be a refrigerator compartment or a freezer compartment. The inner container (3) has walls (5, 6), which are vertical side walls. Furthermore, the inner container (3) has a top wall (7) and a bottom wall (8). A rear wall (9) is also provided. In one embodiment, the walls (5) to (9) can directly define the storage compartment (4).However, it is also possible that additional wall elements are provided that are separate from walls (5) to (9) and partially or completely cover at least one of the walls (5) to (9) facing the recording room (4). Such separate walls could, for example, be design elements or other cladding components.

[0036] The household refrigeration appliance also has a door (10) that closes the receiving compartment (4).

[0037] In the exemplary embodiment, a separate rail (11) is arranged on a wall, here on a wall of the inner container (3), for example, the bottom wall (8). In another example, the rail (11) can also be arranged directly on walls separate from the inner container (3), which, for example, as described above, can be cladding elements arranged in the receiving space (4) for one or more walls of the inner container (3). The rail (11) can therefore also be arranged on a different wall, for example, on a wall that rests on the bottom wall (8) from above and is a separate wall. This wall does not necessarily have to be part of the inner container (3).

[0038] It is also possible that a wall, which is intended for the mounting of the separate rail (11), is permanently (i.e., not without destruction) installed in the household refrigeration appliance (1). However, it is also possible that such a wall can be removed from the receiving space (4), for example. This can be done non-destructively and reversibly. Such a wall could, for example, be a horizontal panel, such as a shelf. A lid of a food storage system could also be such a wall, on which at least one such rail (11) could be arranged and attached from above in the vertical direction (y-direction) of the household refrigeration appliance (1), and then additionally attached to other walls.

[0039] In the exemplary embodiment, the rail (11) is a guide rail. This means that it is designed to guide a separate additional appliance component. Such an appliance component (12) can, for example, be a tray or other box. This appliance component (12) is preferably designed to hold food. Such an appliance component (12) can be reversibly removed from or inserted into the receiving space (4). In particular, it is possible that such an appliance component (12) can be guided and moved in the depth direction (z-direction) of the household refrigeration appliance (1) by means of the at least one rail (11), and in particular, that it can be moved linearly in this spatial direction.

[0040] In Fig. 2 An embodiment of a rail (11) is shown. The rail (11) is preferably formed in one piece. It may preferably be made of plastic. The rail (11) is formed as an elongated element. It has a longitudinal axis A. The rail (11) is preferably arranged or installed in the receiving space (4) such that its longitudinal axis A is oriented in the depth direction (z-direction) of the household refrigeration appliance (1).

[0041] In particular, it can be arranged directly on a horizontal wall, for example, one formed by the floor wall (8). This wall has a top surface (8a) facing the receiving space (4). The rail (11) sits directly on this surface in its assembled final state.

[0042] The rail (11) has a side wall (13). The side wall (13) is vertically oriented. It is oriented in the vertical direction. The vertical direction here is the y-direction, which is also the vertical direction of the household refrigeration appliance (1). In particular, this side wall (13) forms a lateral boundary wall of the rail (11). In the assembled final state, it faces the receiving space (4). This means that, in one embodiment, the rail (11) can be attached to the immediately adjacent, and in particular touching, positioning of another wall, for example, a vertical side wall, such as the side wall (6). In this context, the side wall (13) of the rail (11) faces away from this mounting wall, as formed here by the vertical side wall (6). As a result, the side wall (13) is exposed and always accessible.

[0043] The rail (11) has a snap element (14). The snap element (14) is integrated into the rail (11). The snap element (14) is thus formed integrally with the rail (11). In the exemplary embodiment, the snap element (14) is formed in the side wall (13). The snap element (14) is an elastically resilient element. In particular, this snap element (14) extends laterally away from the side wall (13) and is arranged to cantilever freely in this respect. The snap element (14) thus extends laterally perpendicular to the longitudinal axis A. It is arranged to cantilever freely in this respect. The snap element (14) has an engagement part (15). This is intended to engage in a snap element receptacle (16) ( Fig. 4 ) to snap into place against the wall, in particular the floor wall (8).

[0044] The snap element (14) is elastically springable upwards and downwards about an axis that runs parallel to the longitudinal axis A.

[0045] Furthermore, in the exemplary embodiment, the snap element (14) has a roof section (17). This is directly connected to the engagement part (15). Viewed vertically, it adjoins the engagement part (15) from above. As can be seen, the roof section (17) extends, at least in some areas, beyond the dimensions of the engagement part (15). The roof section (17) thus projects beyond the engagement part (15), particularly in the horizontal direction.

[0046] When the rail (11) is mounted on the wall (8), the roof section (17) can form an upper stop which, when the snap element (14) is engaged in the snap element receptacle (16), is positioned outside the snap element receptacle (16). The roof section (17) can then cover this snap element receptacle (16) from above, at least partially. In particular, when viewed vertically from above, the surface of the snap element receptacle (16) is then covered by this roof section (17).

[0047] In one embodiment, the rail (11) has a first coupling element (18). This element is arranged on a rear side (19) of a base element (20) of the rail (11). The base element (20) can be described as beam-like. As can be seen, this first coupling element (18) extends axially, and thus in the direction of the longitudinal axis A, from this rear side (19) cantilevering freely to the rear. It therefore projects outwards in this respect. The coupling element (18) is, in particular, a plug-in element.

[0048] The first coupling element (18) is designed for direct mechanical coupling with a first coupling element receptacle (21). The first coupling element receptacle (21) is a plug-in receptacle. It is located on a second wall that differs from the horizontal wall. This second wall is formed in particular by the rear wall (9).

[0049] Furthermore, in the exemplary embodiment, the rail (11) is provided with a second coupling element (22) ( Fig. 3 ) exhibits. In this regard, in Fig. 3 A view of the rear side (19) of the rail (11) is shown. This second coupling element (22) is formed on another side wall (23) of the rail (11), in particular of the base element (20). It is, in particular, manufactured integrally with it. The second coupling element (22) projects laterally in the width direction (x-direction) and thus cantilevers freely from this further side wall (23) of the rail (11). It cantilevers freely in the opposite direction to how the snap element (14) projects from the wall (13). The second coupling element (22) is preferably a plug-in element. It is designed to engage in a second coupling element receptacle (24) ( Fig. 4 ) to couple. The second coupling element receptacle (24) is integrated into a third wall in this context. The second coupling element receptacle (24) is, by way of example, a plug-in receptacle. Here too, it is designed only for inserting a plug-in element. This is correspondingly the case with the first coupling element receptacle (21) in an exemplary embodiment. In this exemplary embodiment, the third wall is the vertical side wall (6).

[0050] As in Fig. 2 As can be seen, the snap element (14) is formed in the front third of the rail (11) when viewed in the direction of the longitudinal axis A. In one embodiment, the first coupling element (18) is formed in the rear third of the rail (11), particularly at a rear end (25). The second coupling element (22) is preferably formed in the front third of the rail (11). In the assembled final state of the rail (11), the side wall (23) is intended to face this third wall, here the vertical side wall (6), preferably arranged directly adjacent to it, or at least partially abutting it.

[0051] The to Fig. 2 The rail (11) described above is intended for installation in a corner area on the left side when viewed from the front, between the bottom wall (8), the rear wall (9), and the left-hand vertical side wall (6). It may also be intended, in particular additionally or instead, that a rail (11) is also designed for installation in a corner area on the right side when viewed from the front, between the bottom wall (8), the rear wall (9), and the opposite vertical side wall (5). This rail (11) is then designed such that, when viewed from the front, the snap element (14) is located on the inside in the width direction, i.e., facing the vertical side wall (6) and thus away from the vertical side wall (5).In contrast, the second coupling element (22) is then oriented towards the vertical side wall (5) and engages in a second coupling element receptacle (24) formed and integrated there, in particular being inserted and coupled in the width direction.

[0052] Furthermore, in Fig. 2 As can also be seen, in one embodiment a roller receptacle (26) can be formed in the rail (11), in particular integrated therein. A separate guide roller (not shown) can be inserted into this roller receptacle (26), on which the device component (12) can then roll from above.

[0053] In particular, the snap-in element receptacle (16) is designed as a trough-like recess. Specifically, it is designed as a blind-hole-like recess. In particular, it is designed without any openings. In an exemplary embodiment, a corresponding design can also be provided for the first coupling element receptacle (21) and / or for the second coupling element receptacle (24).

[0054] In particular, the rail (11) is attached to several walls only by mechanical and detachable coupling connections. Specifically, it is attached to three different walls only by the three separate mechanical coupling connections mentioned here.

[0055] In Fig. 5 is in a perspective view a part of the household refrigeration appliance (1) according to Fig. 1 The rail (11) is shown here in an intermediate, assembled state. In this intermediate, assembled state, the first rear coupling element (18) already engages with the first coupling element receptacle (21). This means that the components are already interlocked and thus nested together. As a result, the rail (11) is pre-fixed to a certain extent, so that subsequently, as indicated by the arrow in Fig. 5 As indicated, a pivoting movement of the rail (11) in the width direction can occur. In this respect, a pivot bearing is formed by the coupling connection between the first coupling element (18) and the first coupling element receptacle (21), which is not yet coupled in its final state. In this embodiment, the rail (11) is then pivoted towards the third wall, here the vertical side wall (6), so that the front end of the rail (11) is moved towards the third wall (6). This continues until the snap element (14) snaps into the snap element receptacle (16) and the second coupling element (22) couples with the second coupling element receptacle (24), specifically creating a plug connection, i.e., in this case, an exclusively plug-in connection.

[0056] In Fig. 6 In this regard, a top view of the arrangement according to Fig. 5 This is shown. This coupled intermediate state in the rear area can be seen.

[0057] In Fig. 7 is the order according to Fig. 5 shown, however, the rail (11) is shown in the already described assembled final state.

[0058] In Fig. 8 is an enlarged section of the illustration in Fig. 7 shown. The snapped end position of the snap element (14) in the snap element receptacle (16) can be seen.

[0059] Furthermore, in Fig. 8 A guide track 27 is also shown. The guide element of the device component 12 can engage in this guide track. In this example, the guide track 27 is limited at the top, in particular by a web 28.

[0060] In particular, and also more generally, this end position is supported by the rail (11) bearing against the wall (6). This wall (6) provides a counter-bearing for the engagement of the snap element (14) in the snap element receptacle (16). Specifically, the third wall (6), in the direction perpendicular to the longitudinal axis A and here in the width direction, presses the snap element (14) into the snap element receptacle (16). As a result, a surface area (15a) of the snap element (14), in particular the engagement part (15), which faces away from the third wall (6), is pressed against a surface area (16a) of the inside of the snap element receptacle (16) facing the wall (6). This achieves the locked and snapped-in state.During assembly, when the rail (11) reaches the wall (6) at its front end, particularly by pivoting, the snap element (14), which has been elastically pressed upwards by resting on the base wall (8), automatically snaps downwards from this pre-tensioned state into the snap element receptacle (16). It is then precisely positioned in the snap element receptacle (16), at least in the aforementioned surface areas (15a, 16a). However, an arrangement with a small amount of play is also possible. This is possible if the play, measured in the lateral direction, is less than the insertion depth of the coupling element 22 into the coupling element receptacle 24. The play is preferably a maximum of 2 mm, and particularly a maximum of 1 mm. This prevents unwanted wobbling of the rail 11 at this point.

[0061] In particular, the aforementioned surface area (15a) of the engagement part (15) can therefore also be completely vertical. In another embodiment, the engagement part (15) can also have an engagement lug that projects freely to the side in a bulging manner. This engagement lug can then snap into a preferably existing recess in the snap element receptacle (16). The snap connection is then self-locking in the vertical direction.

[0062] In Fig. 9 is the arrangement in Fig. 8 Shown in a perspective section view. The section plane is drawn here through the width direction and the height direction in the area of ​​the snap connection between the snap element (14) and the snap element receptacle (16).

[0063] In Fig. 10 is the representation in Fig. 9 shown in the section plane and it is a sub-area of Fig. 9 depicted.
