Description

[0001] One aspect of the invention relates to a support device for a household refrigeration appliance, comprising a support plate and a separate adapter part which can be attached to the support plate by at least one snap connection. Another aspect of the invention relates to a method.

[0002] A food storage container is known, for example, from WO 2004 / 038312 A1. There, recesses are formed in a lid of the food storage container in which plate-like and flat flaps are pivotably mounted.

[0003] A refrigeration unit with a pull-out drawer is known from WO 2016 / 037 857 A1. It is provided that a guide rail is arranged on a plate. The guide rail is positioned only on one side of the plate. A separate adapter element can be snapped onto this guide rail. A tray can be attached to or placed on this strip-shaped adapter element. The tray can then be moved along this adapter element in the depth direction.

[0004] From DE 10 2020 202 045 A1, a support device with a snap-on guide rail is known. The rigid snap elements result in a relatively hard snap-on connection, which also makes it difficult to release the guide rail.

[0005] The object of the present invention is to create a carrier device in which the snapping of the guide rail to it is improved, so that easier release is made possible.

[0006] This task is solved by a supporting institution and a procedure in accordance with the independent claims.

[0007] One aspect of the invention relates to a support structure for a household refrigeration appliance. The support structure comprises a support plate. The support structure includes at least one adapter part separate from the support plate. This adapter part can be attached to the support plate by at least one snap connection. The adapter part is designed, in particular, as a support and / or guide device for an additional component. The adapter part has a gripping element, and this gripping element engages an edge of the support plate. The gripping element is snapped to the support plate by at least one snap connection. The adapter part has several elastically deformable retaining elements, which are reversibly detachable and pre-tensioned in connection with retaining element receptacles on the support plate.

[0008] The adapter part can be attached to the carrier plate by at least one non-destructively detachable and, in particular, only mechanical fastening connection, or is attached to it. This means that in the assembled final state, the adapter part grips the edge of the carrier plate. The edge is therefore gripped from above, from the side, and from below. The adapter part is elastically coupled to the carrier plate by at least one detachable fastening connection.

[0009] This simplifies assembly and disassembly. In particular, the required force is reduced and abrupt force peaks are avoided. This also reduces or prevents wear and tear and damage to any of the components during assembly and disassembly.

[0010] This enables an improved coupling and decoupling connection. In particular, disconnection is simplified. The force required to detach the adapter part is reduced. This results in particularly user-friendly handling, especially disassembly, of the adapter part. It also reduces potential damage and accelerated wear of the contact surfaces between the adapter part and the carrier unit, especially during repeated assembly and disassembly.

[0011] Nevertheless, a secure and mechanically stable attachment of the adapter to the mounting plate is achieved. This also allows for more precise positioning of the adapter on the mounting plate over the long term. Even when the weight and displacement forces of the attached container act on the adapter, it remains fixed in position on the mounting plate. Unwanted movement of the adapter relative to the mounting plate is thus prevented.

[0012] The adapter can be a guide rail for additional components. It can also be a support for shelves such as baking trays, pizza trays, etc. Furthermore, the adapter can be designed to accommodate a telescopic extension. A bottle rack could also be attached to the adapter. These are also examples of additional components.

[0013] The adapter part is, in particular, an elongated rail or strip. This longitudinal extension allows the gripping part and / or the engagement element to create a stiffening effect. The gripping part and / or the engagement element thus also act as stiffening elements for the guide rail.

[0014] In an advantageous embodiment, the gripping element has a U-shaped cross-section. This cross-section is perpendicular to a longitudinal axis of the adapter. When the adapter is mounted on the carrier plate and the carrier device is arranged as intended, this longitudinal axis of the adapter extends in the depth direction. This U-shape results in a particularly rigid design. Furthermore, this U-shape allows for complete gripping of the carrier plate's edge. This means that, due to this specific cross-sectional geometry, the gripping element has a groove into which the carrier plate's edge is inserted. The edge, and thus an edge region of the carrier plate containing the edge, is therefore gripped from three sides: the top, the vertical edge, and the bottom. This enables a particularly stable mounting.Last but not least, this design also provides edge protection for the edge of the carrier plate through the adapter part.

[0015] In an advantageous embodiment, the gripping part is provided to have an upper boundary wall.

[0016] In one embodiment, the adapter part has a first type of elastically deformable retaining elements. The adapter part has at least one first elastically deformable retaining element of this first type. The adapter part also has, in particular, a second type of elastically deformable retaining elements that differs from the first. It has at least one second elastically deformable retaining element of this second type.

[0017] In one embodiment, a first type of elastically deformable retaining element is a snap-fit ​​element, and at least one snap-fit ​​element is designed as an elastically deformable retaining element. A retaining element receptacle is designed as a snap-fit ​​element receptacle. This is a very advantageous embodiment because it allows for the realization of different retaining connections with different retaining elements, particularly reversibly detachable and connectable ones. With regard to positional and / or installation space requirements, this enables a particularly advantageous, mechanically detachable connection of the adapter part to the support structure, while simultaneously allowing for simple assembly and, in particular, a force-reduced removal of the adapter part from the support plate.In particular, these multiple retaining connections with different elastic retaining elements ensure a very secure and positionally fixed arrangement of the adapter part on the carrier plate. The at least two different types of elastic retaining elements differ primarily in their geometry, direction of action, and / or how elastically they deform.

[0018] In one embodiment, the first type of retaining element provides a positional support for the adapter part on the carrier plate in a first spatial direction. In particular, this first spatial direction is the width direction.

[0019] In one embodiment, the second type of retaining element provides a positional support for the guide rail on the support plate in a second spatial direction that differs from the first. In particular, this second spatial direction is a vertical direction.

[0020] At least one type of retaining element can also provide a positional support for the adapter part in several spatial directions.

[0021] In one embodiment, the first elastically deformable retaining element of the first type has a U-shaped element, or is such a U-shaped element. This element has a lower leg and an upper leg when viewed in the vertical direction of the support device. This allows for elastic deformation of this geometrically specified and individually oriented retaining element in the vertical direction. Thus, the U-shape is a U arranged horizontally, at 90° to the basic orientation of a U-shape.

[0022] In one embodiment, the lower U-shaped leg is freely cantilevered. This provides a particularly advantageous elastic spring action for this locally specified U-shaped leg. Coupling with a corresponding retaining element receptacle is thus very simple, while still achieving a secure mechanical fit. In particular, this geometry and orientation of the first retaining element also allows for easier and less forceful release of the connection, so that the adapter part can also be removed from the carrier plate with less force.

[0023] In one embodiment, the first elastically deformable retaining element is a snap element. This can be snapped into, or is snapped into, a snap element receptacle, which is an example of a first retaining element receptacle.

[0024] A snap connection is a mechanically stable and secure connection that is also easy to assemble.

[0025] In one embodiment, the upper leg of the U-shape of this first retaining element, in particular the snap element, is integrally formed with a roof wall of the gripping part. Specifically, this leg terminates at this roof wall. It is, in particular, formed integrally with this roof wall. This enables a mechanically localized connection of this U-shaped element to the guide rail, namely to the specific gripping part. By connecting this leg of the U to this roof wall, the corresponding mechanical stability of the entire first retaining element, in particular the snap element, is also supported at this point. In this respect, corresponding forces are absorbed when the U-shape compresses vertically.In this respect, the upper U-shaped leg is elastically stiffer and more positionally stable compared to the lower U-shaped leg, so that the desired elastic deformation of the lower U-shaped leg is particularly precise and as required. This also makes mounting and dismounting the adapter part from the carrier plate easier and requires less force.

[0026] In one embodiment, the lower U-leg has an integrated coupling hook. Specifically, this hook is integrally formed on the underside of the lower U-leg, facing away from the upper U-leg in the vertical direction. This coupling hook thus advantageously projects freely downwards from the lower U-leg in a vertical direction. When the first retaining element, particularly the snap-in element of the first type, is engaged, this coupling hook is snapped into an upwardly open recess of the snap-in element receptacle from above. This enables a particularly advantageous operating concept for generating the snap-in connection and for ensuring a secure position. In particular, this also allows for the simple and user-friendly release of this snap connection.The lower U-shaped leg with the coupling hook can be easily actuated or elastically deformed during disassembly, making it easy to release the coupling hook from the snap element receptacle in terms of assembly technique and force required.

[0027] When the first snap element is mounted in the snap element receptacle, this U-shape is compressed in the vertical direction, so that the lower leg of the U is pressed onto the recess of the snap element receptacle and the coupling hook is pre-tensioned and pressed into this recess.

[0028] In one embodiment, the first retaining element, in particular the snap-in element, of the first type is formed in a middle third of the length of the adapter part, measured particularly in the depth direction of the support device. In particular, this first retaining element, in particular the snap-in element, is formed in a middle fifth of the length of the adapter part. This relatively central, in particular mid-position of the first retaining element along the longitudinal direction particularly supports the retention of the adapter part on the support plate. This central mechanical coupling point also enables the absorption of corresponding forces to be carried out uniformly, and tilting and spreading of the support rail can be better avoided. Furthermore, this specific position of the first retaining element also makes it possible to provide only a single such retaining element on the guide rail.This also minimizes the number of these specific first retaining elements, especially snap elements of the first type.

[0029] In one embodiment, a second type of elastically deformable retaining element is an elastically deformable clamping element. At least one elastically deformable clamping element is designed as a second retaining element. A retaining element receptacle is designed as a clamping element receptacle.

[0030] In one embodiment, the second retaining element of the second type is a U-shaped element, which has a lower leg (viewed in the vertical direction) and an upper leg (viewed in the vertical direction), thus enabling elastic deformation in the vertical direction. In particular, the orientation of the U-shape is also realized here.

[0031] In one embodiment, the lower U-shaped leg of this second, elastically deformable retaining element is integrally formed with a bottom wall of the gripping part. In particular, it is formed integrally with it. The upper U-shaped leg of this second retaining element, especially the clamping element, is cantilevered. When the second retaining element of the second type is clamped, this upper U-shaped leg is arranged in a laterally open, pocket-shaped retaining element receptacle, especially the clamping element receptacle, with both legs resting against the walls of the retaining element receptacle, and in particular being pre-tensioned against them in the vertical direction by elastic compression.This specific geometric design and individual orientation of this second retaining element, particularly the local arrangement of a freely cantilevered U-shaped leg and a U-shaped leg that is fixed at one end and therefore not freely cantilevered, allows for highly individualized deformation and coupling with a very specific retaining element receptacle. This provides particularly advantageous support for the previously mentioned support in the second spatial direction. Furthermore, this configuration allows for a less forceful removal of the adapter part from the mounting plate. This U-shape and the corresponding elastic deformation in the vertical direction facilitate the easier removal of this compressed U-element from the individually shaped retaining element receptacle, especially the clamping element receptacle.

[0032] In one embodiment, several, in particular at least two, and in particular four, second, elastically deformable retaining elements, in particular clamping elements, of the second type are formed on the adapter part. They are, in particular, integrated into the adapter part. This means that they are formed, and in particular manufactured, as a single piece with the adapter part. This is particularly advantageous when the adapter part is made of plastic. In this context, it can be an injection-molded component.

[0033] Viewed in the depth direction of the support structure, a second elastically deformable retaining element is positioned in front of the first elastically deformable retaining element of the first type. At least one further second retaining element is positioned behind the first retaining element in this depth direction. Thus, the adapter part exhibits a very specific series arrangement of different elastically deformable retaining elements in this depth direction. The first retaining element in this series is essentially surrounded by at least two second retaining elements, or rather, extended forward and backward. This creates a highly customized retaining element system.

[0034] In particular, it is provided that a first, elastically deformable retaining element is supplemented at the front by two second, elastically deformable retaining elements and at the rear by two second retaining elements. In this series of, in particular, five retaining elements, the first retaining element is positioned centrally between each pair of retaining elements. However, in the depth direction, these retaining elements are spaced apart from each other on the adapter part.

[0035] In one embodiment, the adapter part has a further type, in particular a third type, of elastically deformable retaining elements, different from the first type and / or the second type. This third type of elastically deformable retaining elements has at least one third elastically deformable retaining element, in particular a deformation element, of this third type. In particular, two third retaining elements are formed on the adapter part. The third type of retaining element differs from the first type and the second type of retaining elements in the shape of the retaining element and / or in the orientation of the retaining element and / or in the functionality of the retaining effect.

[0036] Preferably, the third, elastically deformable retaining element is an arc that is elastically deformable in the width direction and terminates at each end in a base wall of the gripping part. This specific geometry and individual connection result in highly individualized elastic deformation behavior in both direction and type. This also facilitates an advantageous scenario for the assembly and, in particular, the disassembly of the guide rail. Specifically, it enables release with reduced force. Nevertheless, in the assembled state, a particularly precise positioning of the guide rail is ensured, and changes in position in at least one spatial direction, especially a third spatial direction, are advantageously avoided.

[0037] In one embodiment, the gripping part has a base wall with at least one laterally open and rigid recess. When the adapter part is mounted on the carrier plate, a rigid fixing block, formed on the carrier plate, engages in this recess. This engagement is specifically realized in the lateral direction. This provides additional positional fixation or support for the guide rail on the carrier plate, in addition to the various retaining elements. The preferably relatively central, and especially central, arrangement of the first retaining element along the adapter part creates a quasi-center-holding connection, particularly a center-snap connection. This allows for the improved absorption of forces acting on the adapter part in the lateral direction at a front or rear end.At most, a slight rotation of the guide rail is possible in relation to this first holding element, in particular the first snap element, and its position, but this is avoided by at least one other holding element of the second type and / or the third type.

[0038] These additional retaining elements prevent the adapter part from rotating around a vertically oriented axis. In particular, the aforementioned recess and the fixing block also support positional fixation of the guide rail on the support plate in the depth direction.

[0039] In an advantageous embodiment, the edge region of the carrier plate is formed by a separate edge section. The carrier plate may, in this context, comprise a plate section. This plate section may, for example, be made of glass or a transparent plastic. This edge section is arranged at the edge of this plate section. It may, for example, be glued or clipped on. Other forms of connection are also possible. The edge section may be part of a frame that at least partially surrounds the plate section. The edge section may be formed in one piece. It may be made of plastic. The edge section extends over the entire length of one edge of the plate section.

[0040] Preferably, the adapter part is designed as a single piece. It can be made of plastic.

[0041] In one embodiment, the adapter part can have a receptacle for holding an additional component designed as a separate lid. In particular, the lid is arranged below the support structure (viewed vertically) and is designed to close a shell, which may be part of an additional component. The lid can be placed onto the shell, and the shell is arranged below the lid (viewed vertically).

[0042] One aspect of the invention relates to a system with at least one additional component and a carrier device as designed according to the above-mentioned aspect or as designed according to an advantageous embodiment thereof.

[0043] One aspect of the invention relates to a food storage container for a household refrigerator. This container can be an add-on component in its entirety, or a part of the food storage container can be an add-on component. This food storage container includes a tray for holding the food. Furthermore, the food storage container preferably has a lid separate from the tray. This lid can be placed on the tray to close it. In particular, the food storage container has a support structure, as designed according to the aspect mentioned above or according to an advantageous embodiment thereof. This allows the food storage container to be used for storing specific food items and also serves as a support for another container that can be positioned on top of it. This other container can be a simple tray.In an advantageous embodiment, the container can also be designed as a food receiving container with a tray and a separate lid.

[0044] Furthermore, in one embodiment, the food receiving container has a ventilation device with which an exchange of air between the environment and the interior of the food receiving container can be carried out.

[0045] Another aspect of the invention relates to a household refrigeration appliance with at least one carrier device according to one of the above-mentioned aspects or an advantageous embodiment thereof and / or a system according to the above-mentioned aspect.

[0046] A household refrigeration appliance can be a refrigerator, a freezer, or a combination refrigerator-freezer. A household refrigeration appliance has a housing that includes at least one storage compartment for food.

[0047] The food storage container can be arranged within the storage space and, particularly when the lid is closed on the tray, forms a separate, enclosed storage area. The food storage container can, in particular, be a food storage container in which individual storage conditions, especially temperature and / or humidity, can be set.

[0048] This makes it possible to set different storage conditions compared to the rest of the storage area. This is particularly advantageous for storing specific foods such as fruits or vegetables, or meats such as fish.

[0049] The terms "top", "bottom", "front", "back", "horizontal", "vertical", "depth direction", "width direction", "height direction" indicate the positions and orientations given when the carrier device, container or device is used and arranged as intended.

[0050] Further features of the invention are evident from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as those subsequently mentioned in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments of the invention are also to be considered as encompassed and disclosed that are not explicitly shown and explained in the figures, but which can be derived and generated from the explained embodiments by separate combinations of features.

[0052] In the figures, identical or functionally equivalent elements are given the same reference symbols.

[0053] In Fig. 1 An exemplary illustration shows a household refrigeration appliance 1, which here is configured as a combination refrigerator-freezer. It can also be a device configured solely as a refrigerator or solely as a freezer. The household refrigeration appliance 1 has a housing, which can also be referred to as a body 2. The household refrigeration appliance 1 also has an inner compartment 3. The walls of the inner compartment 3 define a first interior space or receiving compartment 4, which is a refrigerator compartment, and, for example, a second interior space or second receiving compartment 5 located below it, which is a freezer compartment. The receiving compartment 4 generally serves for frost-free cooling of goods, preferably at temperatures between +4 °C and +8 °C. However, the receiving compartment 4 can also be configured as a zero-degree compartment, particularly for keeping fruit or vegetables fresh.The first recording room 4 is accessible when door 6, which closes off the front of the first recording room 4, is open.

[0054] The second storage compartment 5 is generally used for deep-freezing frozen goods, for example at -18 °C. The second storage compartment 5 is accessible when the freezer door 7 is open.

[0055] In the first receiving compartment 4, a refrigerated or fresh food container, which is an example of an additional component, is stored in a pull-out position and has a lid 9 and a drawer or tray 10. As shown, an additional, separate cover 11, for example in the form of a partition such as a glass shelf, can be arranged above the lid 9. The fresh food container represents a first food receiving container 8.

[0056] The inner container 3 has, among other things, two opposing vertical side walls 3a and 3b.

[0057] At least by means of the cover 11, the first food receiving container 8 is separated from the remaining partial volume of the first receiving chamber 4.

[0058] The first food receiving container 8 can be removed from the first receiving chamber 4 without damage. Even when placed in the first receiving chamber 4, the tray 10 can be moved back and forth in the depth direction and thus in the z-direction while still stored in the first receiving chamber 4, in order to access the interior of the tray 10.

[0059] The first food receiving container 8 is arranged, in the vertical direction (x-direction), directly above a preferably existing second container 8'. Preferably, the first food receiving container 8 is located at the position of the second container 8'. The second container 8' can be a first food receiving container 8 in addition to, or instead of, the first food receiving container 8. Preferably, when the first food receiving container 8 is located at the position of the second container 8', it extends further forward in the depth direction than the second container located directly above it. In the embodiment where a further container is arranged above the second container 8', this further container can be mounted on a support structure of the second container 8' so as to be linearly displaceable in the depth direction.

[0060] In Fig. 2 A perspective view shows a section of the household refrigeration appliance 1 in which the first food storage container 8 is arranged. The first food storage container 8, which is completely removable from the first storage chamber 4, preferably has a ventilation device 12. This ventilation device 12 allows air exchange between the environment and a volume space or an interior 13 ( Fig. 2 ) of the first food receiving container 8. The ventilation device 12 is, in particular, a separate module. It can be arranged on the lid 9.

[0061] The ventilation device 12 has a flap 14 which can be pivoted about a pivot axis A oriented in the width direction (x-direction). The flap 14 extends, as shown in Fig. 2 shown, essentially across the entire width of the first food receiving container 8.

[0062] This pivoting flap 14 exposes a ventilation opening when open and closes this ventilation opening when closed. This allows air to escape from the interior 13 of the first food receiving container 8.

[0063] The ventilation device 12 has a support body 15. The support body 15 extends in the width direction (x-direction) over the entire width of the cover 9. It is designed as a beam-like element. In particular, the support body 15 is formed in one piece, especially from plastic.

[0064] The plate-like flap 14 is in Fig. 2 The closed position is shown. The support body 15 is a separate unit from the cover 9. Viewed in the depth direction, the support body 15 is arranged on the front side of the cover 9, in particular directly attached. The cover 9 and the ventilation device 12 thus form a cover module 16. This cover module 16 allows the loading opening of the tray 10 to be covered from above.

[0065] Furthermore, the ventilation device 12 has an actuating element 17. In the present embodiment, this actuating element 17 is a mechanical slide. It is linearly displaceable in the width direction. The actuating element 17 is slidably mounted on a support 18 of the ventilation device 12. The support 18 is a flat surface. In particular, it is a partial area of ​​an upper surface 19 of the ventilation device 12. The support 18 is, in particular, an upper surface of a separate support rail of the ventilation device 12. Viewed in the depth direction, the support 18 defines a top opening 20 of the support body 15 at the front. This top opening 20 is completely enclosed all around. The top opening 20 forms a ventilation opening 21 of a ventilation duct 22 ( Fig. 3 ) of the ventilation device 12. This top opening 20 is therefore also an upper ventilation opening 21 ( Fig. 3 ), as mentioned above.

[0066] At the in Fig. 2 und Fig. 3 In the illustrated embodiment, a pivot axis A, about which the flap 14 can be pivoted, is oriented in the width direction.

[0067] At the in Fig. 2 und Fig. 3 In the illustrated embodiment, the ventilation opening 12 is limited by a completely closed edge 24.

[0068] In Fig. 3 is the representation according to Fig. 2 shown, but with flap 14 in the open position. For this, flap 14 is pivoted downwards about pivot axis A.

[0069] The shell 10 has a front wall 25. This wall has a shell flange or an upper front flange 26. As can be seen, the support body 15 is arranged on a front edge 27 of the lid 9. In particular, a push-fit connection is provided here. For this purpose, the support body 15 has a groove 28 at its rear end ( Fig. 4 ) on. The front edge 27 of the lid 9 is inserted into this groove 28. In particular, a front edge of a cover plate of the lid 9. The cover plate can be made of glass. In Fig. 4 The ventilation device 12 is shown from another perspective.

[0070] In Fig. 5 A perspective view shows the system or arrangement 29 as an exemplary embodiment. The arrangement 29 includes the second food receiving container 8' as an example of an additional component. It also includes a support structure 30. An additional, third container 8" can be received by this support structure 30 and moved in the depth direction. The third container 8" sits directly on top of the support structure 30.

[0071] In Fig. 6 The cover module 16 is shown in a perspective view. This cover module 16 includes the cover 9 and, preferably, the ventilation device 12. In another embodiment, the cover 16 can also be designed without the ventilation device 12 or with a different ventilation device 12.

[0072] In one embodiment, the cover 9 represents an example of a support plate 31. The cover 9 can also be an additional component in another example. The support plate 31 can be part of a support device 30.

[0073] The ventilation device 12 can also be part of this support structure 30. However, it does not have to be part of this support structure 30.

[0074] The carrier plate 31 has a plate part 32. This plate part 32 can be made of glass. It can also be made of a plastic that is at least partially transparent.

[0075] In the exemplary embodiment, the carrier plate 31 also has a strip-shaped first edge section 33. The first edge section 33 is separate from the plate section 32. The first edge section 33 can be made of plastic. It can be formed in one piece. The first edge section 33 can be an elongated beam or a long, narrow rail. This is arranged on a first edge 32a of the plate section 32 oriented in the depth direction. A further, second edge section 34 can be formed and arranged on an opposite, second edge 32b of the plate section 32. This second edge section 34 is preferably designed in the same way as the first edge section 33. The two edge sections 33 and 34 can be part of a frame 35. This frame 35 surrounds the plate section 32 at its edges, in particular completely. The first edge 32a can be a rim edge. The second edge 32b can be a rim edge. The edges 32a and 32b can be lateral edges.

[0076] In Fig. 7 Another embodiment of a carrier unit 30 is shown. The carrier plate 31 differs here from the Fig. 6 In particular, no ventilation device 12 is shown here. However, it may also be present.

[0077] In Fig. 7 Examples of first and second adapter parts 36 and 37 are shown. These adapter parts are support and / or guide elements. In particular, they are guide rails. These adapter parts 36 and 37 are separate components from the carrier plate 31. They are attached to the carrier plate 31 at the opposite edge sides 32a and 32b. In particular, they are attached in a way that allows for non-destructive removal. A permanent connection may also be provided. In the exemplary embodiment, they are not attached directly to the plate part 32. Rather, they are attached directly to the edge parts 33 and 34.

[0078] The adapter parts 36 and 37 are elongated rails. They extend with their longitudinal axes B in the depth direction. They extend over at least 50%, and in particular at least 60%, of the length of the edge sides 32a and 32b.

[0079] The 8" container is directly mounted on these adapter parts 36 and 37.

[0080] Adapter parts 36 and 37 can also be used in the example in Fig. 6 at the relevant points, as in Fig. 7 be arranged on the carrier plate 31.

[0081] In Fig. 8 An embodiment of the adapter part 37 is shown in a perspective view.

[0082] The second adapter part 37 is formed in one piece. It is made primarily of plastic. The second adapter part 37 has, as shown in Fig. 7 and Fig. 8 as in Fig. 9 As can be seen, a gripping element 38 is present. In an advantageous embodiment, this gripping element 38 is U-shaped in a section plane that is oriented perpendicular to the longitudinal axis B of the adapter part 37. The gripping element 38 grips an edge 32a of the plate part 32. In particular, in the illustrated embodiment, it grips the frame part 34.

[0083] Furthermore, the second adapter part 37 is provided to have a guide skid 39. The guide skid 39 is formed on the gripping part 38. The guide skid 39 has an L-shaped cross-section perpendicular to the longitudinal axis B. The L-shape is rotated 180° here. As a result, one base leg of the L-shape forms a horizontal leg 40. A vertical leg 41 adjoins it at the bottom. This arrangement of the guide skid 39 forms a bearing surface 40a. The container 8" rests on this surface.

[0084] Furthermore, the gripping part 38 is provided to have elastically deformable retaining elements. In particular, the gripping part 38 is designed with an upper boundary wall 42. In addition, a lower boundary wall 43 is part of this gripping part 38.

[0085] The second adapter part 37 shows, as shown in Fig. 8 As shown, several elastically deformable retaining elements are mounted. These are reversibly and detachably mechanically connected or coupled in retaining element receptacles of the carrier plate 31. In the coupled final state, these various elastically deformable retaining elements are reversibly and detachably snapped, clamped, and pressed into these retaining element receptacles of the carrier plate 31.

[0086] The adapter part 37 has a first type of elastically deformable retaining element. In the exemplary embodiment, only one first retaining element 44 of this first type of retaining element is formed. This retaining element of the first type 44 is a U-shaped element. It has a lower leg 45 in the vertical direction (y-direction). It also has an upper leg 46 in the vertical direction. This retaining element of the first type 44 is thus essentially a horizontal U. It is defined as being elastically deformable in the vertical direction. In particular, the lower leg 45 of the U is cantilevered. A coupling hook 48 is formed on a lower surface 47 of the lower leg 45. It is formed integrally with the lower leg.

[0087] The upper leg of the U 46 is attached to a vertical side wall 49 ( Fig. 12 ) of the gripping part 38 ending. It is, in particular, integrally formed on it. As can also be seen, this single holding element of the first type 44 is arranged in the direction of a longitudinal axis B of the adapter part 37 in a middle third of its length, in particular in a middle fifth of its length, and especially centrally.

[0088] The adapter part 37 also features a second type of elastically deformable retaining element, different from the first type. In the exemplary embodiment, several second retaining elements of this second type are provided. In particular, at least two, and especially four, elastically deformable retaining elements of the second type 49, 50, 51, and 52 are provided. Retaining element 49 is a first retaining element of the second type. Retaining element 50 is a second retaining element of the second type. Retaining element 51 is a third retaining element of the second type. Retaining element 52 is a fourth retaining element of the second type. These retaining elements of the second type 49 to 52 are clamping elements; they are therefore not snap-fit ​​elements. They are held solely by the clamping forces generated during deformation. These retaining elements of the second type 49 to 52 are designed as U-shaped elements. They are arranged in a horizontal U-shape.The first retaining element of the second type 49 has a lower U-shaped leg 53. It also has an upper U-shaped leg 54. The orientation is such that elastic deformation of the first retaining element of the second type 49 in the vertical direction is permitted as intended. For the sake of clarity, the further retaining elements of the second type 50 to 52 are not further designated with reference numerals, as they are formed identically to the second snap element 49.

[0089] As can be seen, the upper U-leg 54 is freely cantilevered. The lower U-leg 53 is attached here to the bottom wall 43 of the gripping part 38, in particular by being integrally molded.

[0090] As can be seen, viewed in the direction of the longitudinal axis B, two retaining elements of the second type 49 and 50 as well as 51 and 52 are arranged symmetrically to the front and rear of this retaining element of the first type 44, in particular to the first snap element. All retaining elements 44 and 49 to 52 are located vertically below the roof wall 42 of the gripping part 38.

[0091] Furthermore, the exemplary embodiment provides that the adapter part 37 has a third type of elastically deformable retaining element. Several retaining elements of the third type 55 are provided here. These are designed as elastically deformable arcs. They are elastically deformable, particularly in the width direction, and especially only in the width direction. As can be seen from the retaining element of the third type 55, a first elastic arc 57 is firmly attached at its ends 57a and 57b, respectively, particularly to corresponding locations on the base wall 43. The first arc 57 is convexly curved. A second arc 56 forms another retaining element of the third type 55. The retaining element of the third type 55 is an elastic deformation element. It is a pressure element.

[0092] It doesn't snap shut or wedge itself between two walls, but simply presses against one wall.

[0093] In the longitudinal direction, and thus in the direction of the longitudinal axis B, the retaining elements of the third type 55 preferably provided here are the front and rear retaining elements, respectively, in the series of several different retaining elements 44, 49 to 52 and 55. The retaining elements of the third type 55 can also be referred to here as elastically deformable contact elements and do not necessarily have to form a snap-fit ​​connection. In this context, they can therefore engage in a corresponding receptacle and, with the elastically deformable arcs 56, 57, contact a wall of such a receptacle and be elastically deformable and positioned thereon depending on the application of a force. In particular, an elastically deformable plug connection can thus also be realized here. Therefore, these retaining elements of the third type 55 can also be referred to here as elastically deformable form elements.

[0094] Furthermore, in Fig. 8 It can also be seen that the adapter part 37 has recesses open laterally in the width direction, in particular a first recess 58 and a second recess 59. These are rigid recesses 58 and 59. They are designed so that, in the mounted state of the adapter part 37, a fixing block formed on the carrier plate 31, in particular a first fixing block 60 and a second fixing block 61 ( Fig. 10 ) intervenes in the lateral direction.

[0095] In Fig. 9 Adapter part 37 is shown in a view from below.

[0096] The first adapter part 36 is constructed in a manner similar to the second adapter part 37. Preferably, both adapter parts 36 and 37 are symmetrically constructed so that they can be snapped and clamped and elastically pressed onto both the left and right edges of the carrier plate 31 as identical components.

[0097] In the representation in Fig. 9 It can also be seen that the deformation elements or the retaining elements of the third type 55, which are elastically deformable, are elastically deformable in one spatial direction, here in the width direction. In this respect, the retaining elements of the second type 49 to 52 and the first retaining element 44 are elastically deformable in a defined vertical direction. Furthermore, the different orientations, in particular the different freely cantilevered and connecting U-shaped legs of these retaining elements of the first type 44 on the one hand and of the second type 49 to 52 on the other, result in different retaining scenarios, especially the snapping into place of the coupling hook 48, which is only provided for the retaining element of the first type 44. This enables positional locking in the width direction, whereas the retaining elements of the second type 49 and 52 primarily support positional locking in the vertical direction.This is achieved in particular by the pre-tensioned clamping of these retaining elements of the second type 49 and 52 in the vertical direction.

[0098] In Fig. 10 The support unit 30 with the support plate 31 is shown in a perspective partial view. The edge part 33 is also shown. This is preferably formed in one piece, for example, from plastic. Several retaining element receptacles for retaining elements are provided in the edge part 33. In particular, first, second, third, and fourth retaining element receptacles of the second type 62, 63, 64, and 65 are provided here. These are provided here as pocket-like retaining element receptacles 62 to 65 that are open laterally in the width direction. The retaining elements of the second type 49 to 52 fit into these. The retaining element receptacles of the second type 62 to 65 each have a lower limiting wall 62a and an upper limiting wall 62b arranged in the height direction. For the sake of clarity, the corresponding walls of the further retaining element receptacles 63 to 65 are not provided with corresponding reference numerals.The respective lower U-legs 53 and upper U-legs 54 are pre-tensioned against these boundary walls 62a and 62b, which means that they are compressed in the vertical direction and therefore generate a corresponding linear holding force in the vertical direction, with which they are pre-tensioned against these boundary walls 62a and 62b.

[0099] Furthermore, another retaining element receptacle of the first type 66 is formed in this edge section 33. This retaining element receptacle 66, which is also formed in the longitudinal direction in a middle third, in particular in a middle fifth, is intended to receive, in particular only to snap into place, the retaining element of the first type 44, in particular the first snap element. For this purpose, this snap element receptacle, which is laterally open in the width direction, is also formed in a bottom wall 66a with a recess 66b, which can be an example of a cutout. The cutout 66b can be a blind hole or a through hole. During assembly, the coupling hook 48 slides inwards in the width direction over a limiting edge 66c and then snaps into this cutout 66b.By compressing the two U-shaped legs 45 and 46 in the vertical direction, a corresponding downward preload force is generated by the lower U-shaped leg 45, which is freely cantilevered, so that the coupling hook 48 is also pressed downwards into this recess 66b.

[0100] Furthermore, the edge section 33 has counter bearings, which here are formed as stationary side walls, in particular the first side wall 67 and the second side wall 68. The first and second retaining elements of the third type 55 and 56, in particular the deformation elements, are pressed against these in the width direction.

[0101] The edge part 34 is designed in the same way as the edge part 33.

[0102] In Fig. 11 The mounted state of the adapter part 36, which is designed according to the adapter part 37, is shown from below on the edge part 33, so that this partial section provides a view from below of the arrangement according to Fig. 7 shows.

[0103] As can be seen here, and advantageously provided for, the adapter part 36 is designed symmetrically about an axis S. This axis is oriented in the width direction. Therefore, it can be indicated there. The representation in Fig. 11 This also applies in particular to the installation of the adapter part 37 on the edge part 34, whereby the coordinate system shown would be oriented differently.

[0104] In Fig. 12 A section of the support unit 30 is shown in a vertical sectional view. The section plane is formed vertically by the first snap element 44. The section is shown here with the guide rail 36.

[0105] In Fig. 13 is a representation accordingly in Fig. 12 As shown, however, the section plane is formed by a second retaining element, here retaining element 49. The vertically compressed state of the U-shaped element is visible. The upper leg of the U 54 rests against the upper boundary wall 62 under prestress. Bezugszeichenliste
