Description

Technical Field

[0001] One aspect of the present invention relates to a household refrigeration device having a receiving space for receiving food and a rail that can be mounted on a wall. Background Technology

[0002] A household refrigeration appliance is known from EP1926956B1, in which very short, block-shaped coupling elements are arranged on the side wall of the inner container. These coupling elements are fixed to the inside of the side wall of the inner container by mechanical couplings. These coupling elements are used to accommodate other independent components of the household refrigeration appliance, such as shelves or drawers.

[0003] Furthermore, a household refrigeration device is known from US2003 / 0173882A1. A guide rail element is fixed to the inner container by a mechanical coupling. The guide rail in US2003 / 0173882A1 has an integrated elastic element on the vertical wall. Therefore, mechanical positioning and connection with accessories that can subsequently be mounted on the guide rail can only be achieved.

[0004] The mechanical fastening here is merely a simple plug-in or hook-and-loop connection, achieved by pushing the components into each other. All the corresponding elements provided in the prior art for coupling between the sidewalls of the internal container and the coupling element are self-shape-stable and position-fixed. Summary of the Invention

[0005] The objective of this invention is to provide a household refrigeration device and a method by which an independent rail can be easily, mechanically, stably, and precisely fixed in the food receiving space of the household refrigeration device.

[0006] This task is solved by a household refrigeration device based on a preferred technical solution.

[0007] One aspect of the invention relates to a household refrigeration device having a receiving space for receiving food. The household refrigeration device has at least one horizontally arranged wall. Furthermore, the household refrigeration device has at least one rail independent of the wall. The rail is arranged on the upper side of the wall. The rail has an integrated locking element. The wall has a locking element receiving portion in which the locking element engages.

[0008] With such a household refrigeration unit, the rail can be easily, safely, and securely mounted and fixed to the wall from above. Therefore, in terms of the height of the household refrigeration unit, the rail sits from above, particularly directly on the upper side. The mechanical coupling for this purpose is constructed very simply, yet robustly and stably. The corresponding installation forces, as well as the subsequent holding and load-bearing capacities, can be fully withstood without the rail wobbling or otherwise undesirably moving or disengaging from its fixed position. The locking connection is particularly advantageous in this respect because it can be easily engaged and disengaged, thus allowing for reversible multiple coupling and disengagement. Furthermore, the locking connection is highly functional and durable. In particular, locking from above is simple and highly advantageous for user accessibility.

[0009] The rails thus exposed on the wall can also withstand mechanical loads, for example, for accommodating another food receiving container, which is then placed on the rails and may move relative to them. Even if the container has its own weight, the corresponding forces generated when placing and moving the container can be easily absorbed by the rails, which themselves will not make any undesirable movements relative to the wall.

[0010] Therefore, the rails are used, in particular, to accommodate plate-shaped components (e.g., shelves) or to serve as support rails for accommodating food receiving trays or food receiving containers.

[0011] In one embodiment, the locking element is spring-loaded onto the rail. This simplifies the coupling and disengagement of the locking connection. Furthermore, the locking status is easily confirmed, particularly by the locking element engaging with its receiving portion. This can be sensed by touch and sound. The rail's positioning on the wall is always secure, and the target position can be reached quickly and purposefully.

[0012] In one embodiment, the locking element is formed, particularly integrated, and thus formed and arranged in one piece on the vertical sidewall of the rail. This makes free extension, particularly toward the sides, possible, while the locking element remains stably integrated into the base element of the rail (here, the vertical sidewall of the base element). Consequently, the upward and downward springing movements are very precise and persistently constant.

[0013] In one embodiment, viewed from a direction perpendicular to the longitudinal axis of the rail, the locking element is arranged laterally, particularly freely cantilevered, protruding from the rail. Therefore, it is arranged very exposed and extends very independently, making it easily accessible and, in particular, operable by the user to release the locking connection. It is this lateral protrusion perpendicular to the longitudinal axis that advantageously achieves locking in the vertical direction, allowing downward access to the locking element receiving portion. Combined with its position on the vertical sidewall of the rail, the elastic movement and elastic force of the locking element can be achieved very easily and without obstruction, especially in the vertical direction. In this respect, this lateral position is particularly advantageous for accessibility, and the locking element does not obstruct movement forward or backward in the longitudinal direction, thus preventing undesirable lengthening of the rail in the longitudinal direction.

[0014] In one embodiment, the locking element has an engagement portion that engages with the locking element receiving portion in the locked state. Furthermore, the locking element has a top portion distinct from the engagement portion. The top portion abuts, particularly directly, the engagement portion from above. In one embodiment, viewed horizontally, the top portion extends at least partially beyond the dimensions of the engagement portion. Here, "horizontal" specifically refers to a plane extending along the longitudinal axis of the track, or parallel to that plane, and in a direction perpendicular to that plane. This forms a horizontal plane defined by the width and depth directions of the household refrigeration unit. In particular, the top portion extends beyond the dimensions of the engagement portion in this width and / or depth direction of the household refrigeration unit. On the one hand, this mechanically stabilizes the engagement portion; on the other hand, through this geometry, the top portion also forms a height stop for the locking element. Therefore, the locking element does not undesirably extend too deep into the locking element receiving portion. The final locking position of the locking element in the locking element receiving portion is thus advantageously predetermined and achieved, and can also be sensed tactilely during this process. This is especially true when the user manually engages the locking element by directly grasping it and inserting it into the receiving portion. Finally, the geometry of the locking element also simplifies the release of the locking state. Because contact with the top portion of the locking element becomes easier, the locking state can be released more quickly without potentially damaging the locking connection. For example, by grasping the top portion and simply pulling the top of the locking element upwards.

[0015] In one embodiment, the top portion thus forms an upper stop in the height direction, which is arranged outside the locking element receiving portion when the locking element is in the locked state within the locking element receiving portion. Specifically, in this locked state, the top portion at least partially covers the locking element receiving portion from above. Thus, in one example, prevention of additional media from seeping into the locking element receiving portion is also achieved, or at least this is reduced.

[0016] In one embodiment, the rail has a first coupling element at its rear side or rear end along its longitudinal axis. This first coupling element is coupled to a first coupling element receiving portion in the final installed state of the rail. The first coupling element receiving portion is formed on a second wall of the household refrigeration equipment. The second wall is, in particular, not in the same plane as the first wall. The two planes of the first and second walls can be parallel in orientation. However, in particular, these two planes are arranged at an angle to each other. For example, the first wall can be a horizontal bottom wall. The second wall can be a vertically oriented wall. The second wall can, for example, be a rear wall. That is, it can define the receiving space at the rear.

[0017] Along the longitudinal axis of the track, the first coupling element is preferably engaged, and thus particularly axially engaged, into the first coupling element receiving portion. Therefore, viewed from the longitudinal axis, the first coupling element and the first coupling element receiving portion overlap in the coupled state.

[0018] In one embodiment, the first coupling element is oriented rearwardly and cantilevered in the axial direction, and thus in the longitudinal direction of the rail. Therefore, the first coupling element preferably protrudes rearward from the beam-like base or base element of the rail. This achieves a further specific mechanical, particularly purely mechanical, coupling between the rail and a second wall, which is different from the first wall, in both function and position. This supports mechanical fixation and positional fixation of the rail on multiple different walls.

[0019] In one embodiment, the coupling between the first coupling element and the first coupling element receiving portion is a plug-in connection. Specifically, it is a purely plug-in connection and therefore simply a plug-in connection. No locking mechanisms or similar features are provided. This achieves a simple coupling principle, which, despite its simplicity, remains mechanically stable and positionally fixed, contributing to the overall fixation of the rail to the wall.

[0020] In one embodiment, viewed along the longitudinal axis, the rail has a second coupling element, particularly on the second sidewall, which engages with a second coupling element receptacle in the final installed state of the rail. The second coupling element receptacle is formed, in particular, on a third wall of the household refrigeration unit. This third wall is distinct from the horizontal first wall and, preferably, the second wall. In this respect, it is also preferably located in a plane different from either the first horizontal wall or the second wall. Specifically, the 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 when this coupling is formed, the second coupling element and the second coupling element receptacle overlap each other in this direction perpendicular to the longitudinal axis of the rail. Thus, the positioning of the rail in the household refrigeration unit is further improved. This further coupling between the second coupling element and the second coupling element receptacle is also a purely mechanical coupling. It is also particularly capable of being released and reconstructed non-destructively and reversibly.

[0021] Therefore, in one embodiment, the rail can be directly connected to different walls of the household refrigeration unit at three different local locations, respectively, by mechanical means, particularly by mechanical coupling only. This advantageously achieves positional fixation. In particular, the coupling between the second coupling element and the second coupling element receptacle is a plug-in connection. It is, in particular, a purely plug-in connection and thus merely a plug-in connection. The advantages achieved thereby have been explained with respect to advantageous embodiments of the first coupling element and the first coupling element receptacle. In particular, it is specified that the insertion direction of the first coupling element and the first coupling element receptacle, in their preferred embodiment, as a plug-in connection, is perpendicular to the insertion 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 household refrigeration unit and / or, in particular, parallel or coaxial with 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 household refrigeration unit.

[0022] In one embodiment, the locking element receiving portion is a recessed receiving portion. Specifically, it is a blind-hole type recess. This means that the locking element receiving portion is formed without any through-hole and is therefore non-penetrating. In particular, the first coupling element receiving portion is formed as a recess. It can be a blind-hole type recess. Here, a non-penetrating recess is also formed. In one embodiment, the second coupling element receiving portion can also be formed in the same way.

[0023] In one implementation, the rail is formed as a single piece. Therefore, it can also be manufactured as a single piece. It is particularly made of plastic. For example, it can be an injection-molded part. In its final installed state, the rail is fixed to one or more walls of the household refrigeration unit solely by one or more of the aforementioned coupling connections. No further fixing devices are provided, particularly by individual fasteners such as screws.

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

[0025] In one embodiment, the rail has at least one integrated first roller receptacle into which a guide roller, independent of it, can be placed, specifically, the guide roller is at least partially submerged within the first roller receptacle. This guide roller allows for better guidance of the device component relative to the rail when it is mounted thereon. The guide roller is also mechanically and stably arranged within the roller receptacle, while remaining as easily movable as possible relative to it, particularly rotatable.

[0026] In one implementation, a wall is a wall of the inner container, such as the bottom wall. However, the wall can also be a wall independent of the inner container, arranged in the receiving space, at least partially covering a wall of the inner container.

[0027] It is also possible that a wall, constructed according to regulations for mounting rails independent of it, is inextricably arranged in a household refrigeration unit. However, it is also possible that such a wall can be removed, for example, from the receiving space. This can be done reversibly and without damage. Such a wall can be, for example, a horizontal plate, which can be designed as a shelf. The lid of the food receiving system can also be such a wall on which at least one such rail can be arranged and fixed from above in the height direction of the household refrigeration unit, and in particular, additionally fixed to another wall.

[0028] A wall can have at least a double-layered structure. It can have an outer layer. This outer layer can face the receiving space. It can be the layer that the rail subsequently abuts. The outer layer can be made of plastic.

[0029] Another aspect of the invention relates to a method for mounting a rail to the wall of a household refrigeration appliance. This household refrigeration appliance is specifically constructed according to the above-described aspect or a preferred embodiment thereof. In particular, the rail is engaged with a locking element receiving portion by a locking element, thereby securing the rail to the first wall from above via a locking connection. This is particularly a connection that can be released without damage.

[0030] Preferably, during installation, the rail is first introduced into the second coupling element receptacle via a second coupling element. This creates pre-coupling. Specifically, this forms a pivot bearing around which the rail can then move from its position to its final position, where, on the one hand, the rail is locked in the locking element receptacle by a locking element, and on the other hand, the first coupling element is coupled to the first coupling element receptacle. Thus, the rail is preferably detachably secured to three different, particularly differently oriented, walls. In particular, these walls have no through-holes.

[0031] In particular, and generally speaking, the final locking position of the locking element in the locking element receptacle is supported by the contact between the rail and the third wall. The third wall provides a reaction force support for the engagement of the locking element into the locking element receptacle. Specifically, the locking element is pressed into the locking element receptacle by the third wall in a direction perpendicular to the longitudinal axis A (here, the width direction). Thus, the surface area of ​​the locking element (particularly the engaging portion) facing away from the third wall is pressed against a surface area of ​​the inner wall of the locking element receptacle facing the third wall. This achieves a holding and locking state. During installation, when the rail reaches the third wall at the front end (particularly by pivoting), the locking element, which was previously elastically pressed upwards (particularly due to being placed on a horizontal wall, particularly the bottom wall), automatically engages downwards into the locking element receptacle from this pre-tightened state. It then fits precisely within the locking element receptacle, particularly in at least the aforementioned surface area. Attached Figure Description

[0044] exist Figure 1 The diagram shows a simplified view of an embodiment of a household refrigeration device (1). The household refrigeration device (1) can be a refrigeration device, a freezing device, or a refrigeration-freezing combination device. It is constructed to receive food. Therefore, food can be stored and preserved therein.

[0045] A household refrigeration appliance (1) has a housing (2). An internal container (3), independent of the housing (2), is housed within the housing (2). The internal container (3) encloses at least one receiving space (4), which is configured to receive food. The internal container (3) is preferably manufactured by deep drawing. It is particularly made of plastic. The receiving space (4) can be a refrigerator compartment or a freezer compartment. The internal container (3) has walls (5, 6), here being vertical side walls. Furthermore, the internal container (3) has a top wall (7) and a wall (8), which is a bottom wall. Additionally, a rear wall (9) is provided. In one embodiment, walls (5) to (9) may directly define the receiving space (4). However, additional wall elements may also be provided, independent of walls (5) to (9), and partially or completely covering at least one of said walls (5) to (9) toward the receiving space (4). Such independent walls may, for example, be design elements or other decorative components.

[0046] The household refrigeration equipment also has a door (10) that closes the receiving space (4).

[0047] In one embodiment, a rail (11) is arranged independently of one wall (here, the wall of the inner container (3), such as the bottom wall (8)). In another example, the rail (11) may also be arranged directly on a wall independent of the inner container (3), which, for example, as described above, may be decorative components arranged in the receiving space (4) for one or more walls of the inner container (3). Thus, the rail (11) may also be arranged on another wall, for example, on a wall placed above the bottom wall (8) and independent of that bottom wall. Such a wall does not necessarily have to be part of the inner container (3).

[0048] It is also possible that the wall, which is designed to be installed independently of its rail (11), is arranged in a way that is non-removable (i.e., cannot be removed without damage) within the household refrigeration unit (1). However, it is also possible that such a wall can be removed, for example, from the receiving space (4). This can be done reversibly without damage. Such a wall can be, for example, a horizontal plate, as it can be designed as a shelf. The lid of the food receiving system can also be such a wall on which at least one such rail (11) can be arranged and fixed from above in the height direction (y direction) of the household refrigeration unit (1) and, in particular, additionally fixed to another wall.

[0049] In this embodiment, the rail (11) is a guide rail. This means that it is configured to guide other equipment components independent of it. Such an equipment component (12) may be, for example, a tray or other box. The equipment component (12) is configured to receive food. Such an equipment component (12) can be reversibly removed from or placed into the receiving space (4). In particular, such an equipment component (12) can be guided to move in the depth direction (z-direction) of the household refrigeration equipment (1) via the at least one rail (11), especially linearly movable in that spatial direction.

[0050] exist Figure 2 An embodiment of a rail (11) is shown. The rail (11) is formed in particular as a single piece. It is preferably made of plastic. The rail (11) is formed as an elongated element. It has a longitudinal axis A. The rail (11) is arranged or can be installed in a receiving space (4) such that its longitudinal axis A is oriented in the depth direction (z direction) of the household refrigeration equipment (1).

[0051] In particular, it can be placed directly on a horizontal wall, which is formed, for example, by a bottom wall (8). This wall has an upper side (8a) facing the receiving space (4). The rail (11) sits directly on this upper side (8a) in the final installation state.

[0052] The rail (11) has a sidewall (13). The sidewall (13) is vertically oriented. It is oriented in the height direction. The height direction is the y-direction, which is also the height direction of the household refrigeration unit (1). In particular, the sidewall (13) represents the lateral boundary wall of the rail (11). It faces the receiving space (4) in its final installed state. This means that the rail (11) can be installed in one embodiment for positioning in close proximity (especially in contact) with another wall (here, for example, a vertical sidewall, as is possible with sidewall (6)). The sidewall (13) of the rail (11) in this case faces away from the mounting wall, which is formed by the vertical sidewall (6). Therefore, the sidewall (13) is exposed and always accessible.

[0053] The rail (11) has a locking element (14). The locking element (14) is integrated into the rail (11). The locking element (14) is thus formed as a single piece with the rail (11). In an embodiment, the locking element (14) is formed in the sidewall (13). The locking element (14) is here an elastic element. In particular, the locking element (14) extends laterally away from the sidewall (13) and is freely cantilevered in this respect. Therefore, the locking element (14) extends laterally perpendicular to the longitudinal axis A. It is arranged laterally freely cantilevered in this respect. The locking element (14) has a connecting portion (15). The connecting portion (15) is provided as specified for locking to the locking element receiving portion (16) of the wall (particularly the bottom wall (8)). Figure 4 )middle.

[0054] The locking element (14) can elastically bounce up and down about an axis extending parallel to the longitudinal axis A.

[0055] Furthermore, in this embodiment, the locking element (14) has a top portion (17). This top portion is directly connected to the engaging portion (15). Viewed from above in the height direction, it abuts the engaging portion (15). As shown, the top portion (17) extends at least partially beyond the dimensions of the engaging portion (15). Therefore, the top portion (17) protrudes from the engaging portion (15) particularly in the horizontal direction.

[0056] With the rail (11) mounted on the wall (8), the top portion (17) can form an upper stop, which is arranged outside the locking element receiving portion (16) when the locking element (14) is locked in the locking element receiving portion (16). Then, the top portion (17) can cover the locking element receiving portion (16) from above at least a portion. In particular, in a projection view along the height direction from above, the surface of the locking element receiving portion (16) is covered by the top portion (17).

[0057] In one embodiment, the rail (11) has a first coupling element (18). The first coupling element (18) is arranged on the rear side (19) of the base element (20) of the rail (11). The base element (20) can be referred to herein as beam-shaped. As shown, the first coupling element (18) extends freely rearward from the rear side (19) in the axial direction and thus along the direction of the longitudinal axis A. Therefore, it protrudes rearward in this respect. The coupling element (18) is in particular an insert element.

[0058] The first coupling element (18) is configured to be directly mechanically coupled to the first coupling element receiving portion (21). The first coupling element receiving portion (21) is an insertion receiving portion. It is located on a second wall, which is different from the horizontal wall. This second wall is formed specifically by the rear wall (9).

[0059] Furthermore, the embodiment specifies that the rail (11) has a second coupling element (22) Figure 3 ).in this regard, Figure 3 A view of the rear side (19) of the rail (11) is shown. The second coupling element (22) is formed on the other side wall (23) of the rail (11), particularly on the base element (20). In particular, it is manufactured as a single piece. The second coupling element (22) protrudes laterally in the width direction (x direction) and thus also extends freely away from the other side wall (23) of the rail (11). Therefore, it extends freely in the opposite direction to the locking element (14) extending from the wall (13). The second coupling element (22) is preferably an insertion element. It is configured to engage with the second coupling element receiving portion (24) ( Figure 4 The second coupling element receiving portion (24) is formed and integrated into a third wall. The second coupling element receiving portion (24) is exemplarily an insertion receiving portion. It is also intended to be used only for inserting one insertion element. This applies accordingly to the first coupling element receiving portion (21) in one embodiment. The third wall is a vertical sidewall (6) in this embodiment.

[0060] like Figure 2 As shown, viewed from the longitudinal axis A, the locking element (14) is formed at the front third of the length of the rail (11). In one embodiment, the first coupling element (18) is formed at the rear third of the length of the rail (11), particularly at the rear end (25). The second coupling element (22) is preferably formed at the front third of the length of the rail (11). The sidewall (23) faces this third wall (here, the vertical sidewall (6)) in the final installed state of the rail (11). It is particularly arranged adjacent to it, preferably at least partially abutting it.

[0061] Figure 2 The rail (11) described herein is configured to be installed in the left corner region when viewed from the front of the household refrigeration unit, which is located between the bottom wall (8), the rear wall (9), and the left vertical side wall (6). Alternatively, it may be specified, particularly additionally or alternatively, that the rail (11) is also configured to be installed in the right corner region when viewed from the front of the household refrigeration unit, which is located between the bottom wall (8), the rear wall (9), and the opposite vertical side wall (5). The rail (11) is designed such that, when viewed from the front, the locking element (14) is located internally in the width direction, i.e., facing the vertical side wall (6), and thus facing away from the vertical side wall (5). In contrast, the second coupling element (22) faces the vertical side wall (5) and engages in the second coupling element receiving portion (24) formed and integrated therein, particularly inserting the coupling in the width direction.

[0062] In addition, such as Figure 2As shown, in one embodiment, a roller receptacle (26) may be formed in the rail (11), particularly integrated therein. A guide roller, not shown and independent of the roller receptacle, may be placed into the roller receptacle (26), and then the device component (12) may be rolled onto it from above.

[0063] Specifically, it is specified that the locking element receiving portion (16) is a recessed groove. It is specifically formed as a blind hole type recess. In particular, it is formed without penetration. Accordingly, in one embodiment, this can also be specified for the first coupling element receiving portion (21) and / or for the second coupling element receiving portion (24).

[0064] In particular, the rail (11) is fixed to multiple walls only by mechanical and detachable coupling connections. Specifically, it is fixed to three different walls here only by three independent mechanical coupling connections mentioned herein.

[0065] exist Figure 5 In the perspective view, it is shown that according to Figure 1 A portion of the household refrigeration unit (1). The rail (11) is shown here in an intermediate installation state. In this intermediate installation state, the rear first coupling element (18) has been engaged with the first coupling element receiving portion (21). Mutual engagement, i.e., mutual insertion, has been achieved in this respect. Therefore, the rail (11) is pre-fixed to a certain extent so that it can be subsequently (as...) Figure 5 (As indicated by the middle arrow) The rail (11) can pivot in the width direction. In this respect, a pivot bearing is formed by the coupling between the first coupling element (18) and the first coupling element receptacle (21), which are not yet coupled in the final state. The rail (11) then pivots toward the third wall (here, the vertical side wall (6)) in this embodiment, so that the front end of the rail (11) moves toward the third wall (6). This process continues until the locking element (14) locks in the locking element receptacle (16) and the second coupling element (22) couples with the second coupling element receptacle (24), in particular achieving a plug-in connection, i.e., a pure plug-in connection here.

[0066] Figure 6 Showing information about this, based on Figure 5 A top view of the layout. The coupled intermediate state of the rear region can be identified.

[0067] Figure 7 Showing according to Figure 5 The arrangement is as described, but the rail (11) is in the final installation state as described.

[0068] Figure 8 Show Figure 7 The magnified portion of the middle section. The final locking position of the locking element (14) in the locking element receiving section (16) can be identified.

[0069] also, Figure 8 The diagram also shows a guide groove (27). A guide portion of the device component (12) can engage with this guide groove (27). In this example, the guide groove (27) is restricted upwards, particularly by means of a web or tab (28).

[0070] In particular and generally, the final position is supported by the contact between the rail (11) and the wall (6). The wall (6) provides a reaction force support for the engagement of the locking element (14) into the locking element receptacle (16). In particular, the locking element (14) is pressed into the locking element receptacle (16) by the third wall (6) in a direction perpendicular to the longitudinal axis A (here, the width direction). As a result, the surface area (15a) of the locking element (14) facing away from the third wall (6) (especially the engagement portion (15)) is pressed against the surface area (16a) of the inner wall of the locking element receptacle (16) facing the wall (6). This achieves a holding and locking state. During installation, when the rail (11) reaches the wall (6) at the front end (especially by pivoting), the locking element (14), which was previously elastically pressed upward (especially due to being placed on the bottom wall (8)), automatically engages downward into the locking element receptacle (16) from this pre-tightened state. It is then precisely fitted within the locking element receiving portion (16), particularly in at least the aforementioned surface areas (15a, 16a). However, a small gap may also be provided. This is possible when the gap, measured in the width direction, is less than the insertion depth of the coupling element (22) into the coupling element receiving portion (24). The gap is preferably a maximum of 2 mm, and particularly a maximum of 1 mm. This avoids undesirable wobbling of the rail (11) in this location.

[0071] In particular, the surface area (15a) of the engagement portion (15) can also be completely vertical. In another embodiment, the engagement portion (15) may also have an engagement protrusion that protrudes laterally and cantilevered freely.
