Description

One aspect of the invention relates to a hanging device for hanging a food receptacle in a freely projecting manner. The suspension device has a central rail for directly suspending a food receptacle. A further aspect of the invention relates to an arrangement with such a suspension device and a food receptacle. A further aspect of the invention relates to a household refrigeration appliance component.

In the case of household refrigeration appliances, it is known that separate food receptacles are positioned in a defined manner in a household refrigeration appliance component. For this purpose, in particular, a freely cantilever hanging on a hanging device is provided. In this context, freely projecting hanging means that the food receptacle only hangs in this hanging device and is not held downwards by another component or is not seated on such a component. The positioning of the food receptacle is therefore achieved in particular only by this hanging.

In this context, hanging devices are also known, which are arranged, for example, on the inside of a door of a household refrigeration appliance. This allows a door rack representing a food storage container to be attached. Such a configuration is, for example, from DE 10 2009 045 058 A1 famous. The hanging strip there is made of plastic. This reduces stability and load capacity. In addition, it is limited in terms of shape. The usability and applicability in various household refrigeration appliance components is therefore also limited.

In addition, from the WO 2014/19722 A1 a hanging device for hanging a cantilevered food storage container is known. The rail there is also made of plastic.

It is the object of the present invention to create a suspension device that is designed to be more stable. In particular, the usability and thus the usability for a wide variety of purposes should be improved.

This object is achieved by a hanging device, an arrangement and a household refrigeration appliance component according to the independent claims.

One aspect of the invention relates to a hanging device for hanging a food receptacle in a freely projecting manner. The suspension device has a central rail. The central rail is designed for directly hanging in at least one food storage container. The hooking is non-destructively detachable. The food storage container can thus be reversibly hooked in and removed again.

The central rail is U-shaped. It is made in one piece from metal. Such a specifically shaped central rail significantly increases the stability of the suspension device. Due to the U-shape, a wide variety of storage options for food storage containers are achieved. Their positioning on it is also improved as a result. The suspension device as a whole can also be improved by this shape and can be arranged in a mechanically more stable manner on a wide variety of household appliance components. Therefore, the hanging device can also be better used for several purposes. Due to the one-piece design of such a materially and shape-individually designed central rail, the number of components is also reduced. The assembly effort for the suspension device is thus minimized. Last but not least, positional tolerances of individual areas of the suspension device relative to each other can be permanently avoided. In particular, manufacturing tolerances of this component of the central rail that would occur with individual parts are thus also avoided. These are often disruptive with regard to the positional accuracy of these components of the central rail in relation to one another. It is precisely such a design made of metal that enables a more stable design of the central rail. Last but not least, an individual optical appearance of the central rail can be generated. In particular, a one-piece, U-shaped bracket is formed by the central rail.

In particular, the central rail is made of stainless steel. It is therefore also particularly advantageously suitable for a wide variety of uses in household refrigeration appliances. Ambient conditions, which also bring with them very low temperatures and temperature differences, as well as the corresponding influences of moisture, cannot then affect the central busbar. In particular, corrosion phenomena can then also be avoided.

In one embodiment, the central rail has a straight, elongate hanging part. This hanging part is intended to be designed for directly hanging in a food storage container. This elongate, straight hanging part has a first end in the direction of its longitudinal axis. This is designed as a first holding part of the suspension device by bending the material of the central rail. With this first holding part, the entire hanging device can be held and fastened directly to a household appliance component. A second holding part of the suspension device is formed by bending at a second end of the suspension part that is opposite in the longitudinal direction. The U-shape of the central rail is then formed by the suspension part and the holding parts.

In particular, the holding parts therefore protrude at an angle of 90° from the ends of the suspension part. Viewed in the direction of the longitudinal axis of the suspension device, the suspension part is many times longer than the holding parts. This longitudinal axis is oriented in the direction of the U-shape.

In one exemplary embodiment, the at least one holding part is a single-layer plate. In particular, this configuration of the holding part is only a single-layer plate. As a result, this holding part can be made relatively thin and is still mechanically stable due to its design. It is therefore also stiff and provided for direct mechanical coupling to other components of the suspension device or to other components of components external to the suspension device.

In one exemplary embodiment, the suspension device has a coupling part that is separate from the central rail. This coupling part is attached directly to the holding part. The coupling part is intended for direct coupling to a household appliance component. By such a modular design of a suspension device On the one hand, the central rail can be designed as best as possible with regard to its requirement profile, specific to shape and material. On the other hand, the separate coupling part can be designed individually for its intended intended use of the suspension device. In particular, this coupling part can be made of plastic. As a result, it can be implemented as a simple injection molded component. It is therefore also designed to save weight. This holding part of the central rail then also serves as a carrier component for this coupling part.

In one exemplary embodiment, the coupling part has an integrated holding cam receptacle. This retaining cam receptacle is provided for receiving a retaining cam of a household appliance component. This retaining cam is provided to hold the suspension device on the household appliance component. This coupling part is therefore individually configured both component-specifically and functionally. The design made of plastic also makes it possible that no unwanted abrasion or other signs of wear occur when the retaining cams are in direct contact.

In a further exemplary embodiment, the coupling part is designed as a covering cap which also covers the holding part on the outside. Provision can be made for this coupling part to be attached to the suspension part of the central rail. In particular, the central rail can have integrated hollow chambers on the suspension part. The coupling part can be inserted into this. This enables direct mechanical coupling of the coupling part to the suspension part on the one hand and in particular also to the holding part on the other hand. The coupling part can be attached directly to the holding part or snapped on. The holding part in the form of the single-layer plate, in particular, can be formed as an uninterrupted plate. This means that the panel has no holes or edge cuts. This also makes it possible for the coupling part to bear against this holding part over a large area. In particular, the plate is square.

In one embodiment, the holding part has a recess or a cutout. This is a free cut with an open edge. In the assembled state, the coupling part is introduced into this cut-out or into this recess and is also fastened thereto. On the one hand, there is an individual fastening option of the coupling part created on the holding part. On the other hand, this also makes it possible for the coupling part to have an insertion slot into which the holding part extends, so that the coupling part is located on both sides of the holding part in the assembled state. As a result, the holding part is covered as much as possible by the coupling part on the outside and on the inside.

In a further exemplary embodiment, the coupling part has a coupling area which is open towards the rear. This can be, for example, a retaining cam recording. This retaining cam receptacle is designed to receive a retaining cam that is arranged on the household appliance component. A direct mechanical coupling between the retaining cam and the retaining cam receptacle can then also take place as a result. In this context, the suspension device can then in turn advantageously be releasably attached to this household appliance component in a non-destructive manner.

In one exemplary embodiment, the coupling part has a retaining cam receptacle that is open toward the bottom. This is adapted to the downwardly open recess in the holding part. In the mounted state of the coupling part on the holding part, this downwardly open recess in the holding part is covered by the area of the holding cam receptacle in the coupling part and the relevant open shape is nevertheless retained. In this respect, even in the assembled state of the coupling part, a free space is formed in this entire module between the holding part and the coupling part, in which space the holding cam can engage. In particular, a form-fitting engagement can then also take place here.

In a further exemplary embodiment, the holding part is designed as a two-layer plate. On the one hand, this increases the mechanical stability. On the other hand, this configuration also makes it possible for the holding part to be multifunctional. This is because it is then also possible for a retaining cam receptacle and/or a recess for a coupling part of one of the two plate layers to be integrated into this two-layer plate and thus formed in one piece with it. In particular, such a two-layer panel is achieved by simply bending over the material area of the central rail. The two-layer design of the holding part is thus a sort of folded end area of the central rail, which is correspondingly simply bent over at the end, so that this two-layer plate part is formed. In particular, the bend is such that the two Plate layers of this two-layer plate are oriented parallel to one another. In particular, they are arranged congruently with one another.

This also means that a freely projecting front edge of this holding part is a rounded bend. Sharp edges or the like can thus be avoided on this front side of the holding part.

In one embodiment, this holding part is designed in one piece and a first plate layer is oriented parallel to a second plate layer of the holding part.

A compactly constructed holding part can thus also be generated in the width direction.

In one exemplary embodiment, the two plate layers are arranged at least in regions at a distance from one another. A gap is therefore created between these two plate layers. On the one hand, this can serve to accommodate further components. In addition, a certain deformation elasticity is also made possible by this arrangement. In this way, positional and manufacturing tolerances can also be compensated for when the suspension device is arranged on the household appliance component.

In addition, this configuration also creates a certain thickening of the holding part. This can be advantageous if, on the one hand, a holding cam receptacle is to be integrated into this holding part and/or other components of the suspension device are to be fastened to this holding part, in particular at least one panel layer.

In one embodiment, the outer, second board layer viewed in the width direction has a downwardly open recess. This recess, which is open at the bottom, is in particular a retaining cam receptacle for receiving a retaining cam of a household appliance component. In this regard, the retaining cam is provided for retaining the suspension device on the household appliance component.

In particular, this is a U-shaped recess. The relevant U-shape has been rotated by 180° and is thus turned upside down.

In one embodiment, a spacer web of the holding part is formed along the contour of the recess. This spacer bar extends in the width direction of the suspension device. It is thus oriented perpendicularly to the planes in which the two plate layers are each stretched. This spacer web keeps the first layer of panels at a distance from the second layer of panels. In one embodiment, the spacer bar is formed in one piece with the second plate layer. This spacer web makes the retaining cam mount thicker in the width direction. In this respect, a larger contact surface for the retaining cam is formed as a result.

In one exemplary embodiment, it can be provided that this spacer bar is integrated on a separate edge protection element of the suspension device. This edge protection element is a separate component from the central rail. The edge protection element is arranged directly on the second board layer in the recess. A marginal edge of the recess in the second board layer is covered by this edge protection element. On the one hand, no undesirably sharp edges of this recess are exposed. On the other hand, improved coupling with a retaining cam of a household appliance component can thus be achieved. The edge protection element can be a coupling part. It can be designed as a U-bend. It can have a groove into which a peripheral edge of the second panel layer engages.

In one embodiment, the suspension part of the central rail is a straight profile rail. In one exemplary embodiment, the profile rail has a first, upper hollow chamber viewed in the vertical direction of the suspension device. This hollow chamber is formed on an upper edge of a front panel of the rail. Furthermore, in one exemplary embodiment, the suspension part has a second, lower hollow chamber which is formed at a distance therefrom and is also formed in one piece with the suspension part. In particular, this second, lower hollow chamber is formed on a lower edge, viewed in the height direction, of the front panel of the profile rail. In particular, the hollow chambers extend backwards, starting from the front panel, viewed in the depth direction.

In particular, the hanging part is designed as a profiled beam or profiled board. This means that it has a length that is greater, in particular many times greater, than the height and the depth. The suspension part is straight.

By designing the hanging part as a profile rail, individual profile shapes can also be produced. This with regard to increasing the stability of the rail itself, as well as with regard to improved hanging options for food storage containers.

In one embodiment, the profile rail is a roll-formed profile. Especially when it is made of metal, such a roll-formed profile is relatively easy to produce. This roll forming is also advantageous for more complex profile shapes. From a flat plate made of metal, for example a sheet metal plate, for example, the more complex profile part in the form of the profile rail can then be produced by this roll forming. In particular, the one-piece configuration is thus very advantageous and enables a precise shape. A roll-formed profile as a profile rail therefore represents a particularly advantageous exemplary embodiment. In particular, the entire central rail is a roll-formed profile.

In one embodiment, the two hollow chambers are arranged completely behind the front panel. This means that they do not protrude upwards and downwards over the front panel when viewed in the height direction. A profile rail with a compact structure is thus achieved. In addition, this configuration also makes it possible, for example, for the upper boundary wall of the first, upper hollow chamber to also serve as a contact and attachment wall for a food storage container. Thus, a food receiving container not only hangs on a very thin line or on an edge that is formed by the upper edge of the front panel, but on a contact surface that is larger in this respect. A stable positioning is thereby improved.

In one exemplary embodiment, both hollow chambers in particular extend without interruption over the entire length of the front panel. This improves the advantages in terms of stabilization on the one hand and the possibility of coupling with other components of the suspension device, if applicable.

In one exemplary embodiment, at least one of the hollow chambers is formed in a cross section perpendicular to a longitudinal axis of the profile rail on multiple sides, in particular at least on three sides, in particular on four sides. In one embodiment, at least one hollow chamber is designed to be open in such a cross section. In particular, this cross-sectional geometry of a hollow chamber is thus formed with four sides, but this cross-sectional contour is not completely closed in the circumferential direction. On the one hand, this achieves high stability and, on the other hand, allows a certain deformation elasticity of the cross-sectional geometry of the hollow chamber. Precisely the then freely cantilevered leg, which forms one side of this four-sided geometry, can then also spring to a certain extent. Improved attachments of the suspension device to a household refrigeration appliance component can also be achieved in this way. Manufacturing tolerances can then be better compensated by this design.

In particular, both hollow chambers are designed accordingly in this respect.

In one exemplary embodiment, the first, upper hollow chamber is designed with a smaller depth than the lower hollow chamber, viewed in the depth direction of the suspension device. This has advantages in that hanging a food receptacle in the depth direction can also be made possible in a very space-saving manner. On the one hand, the rigidity of the profile rail is particularly advantageously increased by the lower, second hollow chamber, which is deeper in this respect. On the other hand, due to the first, upper hollow chamber, which is reduced in depth in this regard, a free space is also created behind it, into which hanging elements of the food storage container can engage. In particular, in one exemplary embodiment, such a hook-on element of a food storage container does not protrude backwards in the depth direction beyond the extent of the lower, second hollow chamber. This is achieved by the depth-reduced, first and upper hollow chamber. This also enables a space-saving arrangement of the suspension device. Nevertheless, a simple and user-friendly hanging and again removing a food receptacle is made possible. This prevents such a food receptacle from protruding backwards beyond the profile rail.

In one exemplary embodiment, the profile rail has an open configuration at a first end viewed in the direction of its longitudinal axis. This open end is designed as an insertion holder for an additional coupling part of the suspension device, as has already been mentioned above. In addition to or instead of this, the profile rail is designed to be open at a second end, viewed in the direction of this longitudinal axis. In one exemplary embodiment, this open end is designed as an insertion holder for an additional coupling part of the suspension device, as has already been mentioned above. As intended, these open ends are thus formed as coupling points for these coupling parts.

A further aspect of the invention relates to an arrangement with a suspension device according to the aspect mentioned above or an advantageous embodiment thereof. The arrangement also has at least one food storage container that is separate from the hanging device. This food storage container has, in particular, a food storage area and a hanging element. With this hanging element, the food storage container can be hung directly on the profile rail. In particular, it can be hung on it in a freely cantilevered manner. This means, as has already been explained above, that the food receiving container is no longer supported at the bottom or is no longer seated or set up on an additional floor. In particular, in this respect it is only hung on this profile rail.

A further aspect of the invention relates to a household appliance component. In particular, this is a household refrigeration appliance component. In particular, such a household refrigeration appliance component is a door for a household refrigeration appliance. This household refrigeration appliance component has a suspension device according to the aspect mentioned above or an advantageous configuration thereof. In addition to or instead of this, this household refrigeration appliance component can have an arrangement according to the aspect mentioned above.

With the information "top", "bottom", "front", "rear, "horizontal", "vertical", "depth direction", "width direction", "height direction" are the intended use and intended positioning of the hanging device or the Arrangement or the household appliance component specified given positions and orientations.

Further features of the invention result from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description, as well as the features and feature combinations mentioned below in the description of the figures and/or shown alone in the figures, can be used not only in the combination specified in each case, but also in other combinations or on their own, without the frame to abandon the invention. The invention is therefore also to be considered to include and disclose embodiments that are not explicitly shown and explained in the figures, but that result from the explained embodiments and can be generated by separate combinations of features.

Elements that are the same or have the same function are provided with the same reference symbols in the figures.

In 1 an embodiment of a suspension device 1 is shown in a perspective view. The hanging device 1 is intended for freely projecting hanging of a food storage container. The suspension device 1 is therefore also designed for use on a household appliance component. In particular, the suspension device is also intended for use on a household refrigeration appliance component. In particular, it can be arranged in a domestic refrigerator.

The suspension device 1 has a central rail 2 . The central rail 2 is designed for directly suspending a food storage container. The central rail 2, as shown in 1 shown is integrally formed. In particular, it is also made in one piece in this respect. The central rail 2 is U-shaped. It is made entirely of metal. In particular, it is made of stainless steel. The central rail 2 is designed as a U-shaped bracket.

The central rail 2 has a straight, elongated suspension part 3 . This suspension part 3 can be formed like a beam or like a board or as a plate-like strip. Along a longitudinal axis A of the central rail 2, this suspension part 3 is many times longer than the dimensions in the two directions perpendicular thereto. This suspension part 3 is designed for direct suspension or attachment of at least one food storage container. A freely cantilever hanging is possible here. A first holding part 5 is formed on a first end 4 of the suspension part 3 in the direction of the longitudinal axis A. In the exemplary embodiment, this is produced by bending the strip of material from which the central rail is formed. In particular, this holding part is oriented at an angle of 90° or essentially 90° to the longitudinal extent of the suspension part 3 . Viewed in the direction of the longitudinal axis A, a further holding part 7 is formed on a second end 6 of the suspension part 3 opposite the first end 4 . This is also formed by bending the strip of material of the central rail 2 . In particular, a roll forming is provided here.

The holding parts 5 and 7 shown here are each formed in multiple layers. The holding parts 5 and 7 are plate-like in this respect. The first holding part 5 thus has a first plate layer 8 . This is directly connected to the end 4. In addition, this holding part 5 has a second plate layer 9 . This is produced by further bending of the strip of material at the end of the first panel layer 8 . The two plate layers 8 and 9 are oriented parallel to one another. In particular, they are also designed to be congruent. The two plate layers 8 and 9 are directly connected to one another by a rounded bend 11 on a front edge 10 facing away from the hanging part 3 .

The further holding part 7 also has a corresponding configuration.

In 2 is in a to 1 different perspective, the central rail 2 is partially shown. The holding part 5 can be seen here in perspective from below. As shown here, in this exemplary embodiment, the plate layers 8 and 9 are arranged at a distance from one another when viewed in the width direction (x-direction). It is here in the embodiment, a spacer bar 12 is formed, which is oriented in the width direction and a distance between the two plate layers 8 and 9 is maintained. In the exemplary embodiment, the spacer web 12 is formed in one piece on the outer, second board layer 9 in the width direction. In particular, this spacer bar 12 is formed as a U-shaped arc. In particular, this U-shape is turned upside down. As in 2 can also be seen, this second plate layer 9 has a recess 13 . This recess is a recess open towards the bottom. The recess 13 is also designed as an inverted U in terms of its boundary contour. This recess 13, which can also be referred to as a free cut, forms a retaining cam receptacle for receiving a retaining cam. The retaining cam is a separate and external component for the suspension device 1 . It is arranged on a household appliance component. It is intended for direct mechanical coupling to this cam retainer.

In the embodiment in FIG 2 the spacer web 12 forms the edge of this recess 13 .

In particular, it is formed by forming the second plate layer 9 . This spacer bar 12 also enlarges a contact surface 14 for the retaining cam. Not only the edge and thus the thickness of the second panel layer 9 is then provided as such a contact surface, but also the contact surface 14 which is enlarged in the width direction.

The second holding part 7 is also designed in a corresponding manner.

In this exemplary embodiment, the entire suspension device 1 is designed in one piece and is only formed by the central rail 2 .

In 3 another exemplary embodiment of a suspension device 1 is shown. In this embodiment, a central rail 2 is realized, as it corresponds to 1 and 2 has already been explained. In contrast to 1 and 2 However, this spacer bar 12 is not present here. Otherwise, the design of a holding part 5, 7 is the same as in 1 and 2 .

In this exemplary embodiment, the suspension device 1 has a coupling part 15 that is separate from the central rail 2 . This coupling part 15 is a U-shaped arc here. In particular, it is designed in one piece. In particular, it is made of plastic.

This coupling part 15 has a groove 16 . The second panel layer 9 engages in this groove 16 in the area of the recess 13 . This means that a marginal edge 17, which delimits the recess 13, engages in this groove 16 when the coupling part 15 is mounted on the second panel layer 9. The assembled condition in this regard is in 4 shown. A covered embodiment of the cutout 13 is thus provided, so to speak, with the cutout open at the bottom or the cutout 13 open at the bottom being retained when the coupling part 15 is mounted. A retaining cam can thus engage in this lined recess 13 from below. This coupling part 15 can be attached to the second plate layer 9 . In this regard, a clamp connection can also be provided. For example, however, a snap element 18 on the coupling part 15, which is formed in particular in the groove 16, can also snap into a snap receptacle 19 in the second panel layer 9.

In particular, therefore, this coupling part 15 also has an integrated cutout, which is a retaining cam receptacle for receiving a retaining cam of a household appliance component. The recess 13 in the second plate layer 9 is thus also reproduced in the form by the coupling part 15 .

In figure 5 a further exemplary embodiment of the suspension device 1 is shown in a perspective partial illustration. In this configuration is in contrast to 3 and 4 provided that a gap 20 ( Figures 3 and 4 ) between the two plate layers 8 and 9 is filled by a filling element 21.

As in 4 and figure 5 can also be seen, this Koppelelteil 15 is used in one embodiment as a spacer element. Thus, a spacer bar 12, as it is in the embodiment in 1 and 2 is formed in one piece in the second plate layer 9, integrated here in the exemplary embodiment in the coupling part 15. As can be seen, this coupling part 15 also forms a sort of archway, which keeps this intermediate space 20 between the board layers 8 and 9 free in the width direction. Thus, a certain dimensioning of this recess 13 is formed, so that a retaining cam can extensively engage and couple. It is thus only the gap 20 outside of the coupling part 15 filled with this filling element 21. This filling element 21 can in particular be elastically deformable.

In 6 another exemplary embodiment of a suspension device 1 is shown.

In this exemplary embodiment, the central rail 2 is again provided as a one-piece metal component with a U-shape. However, it is provided here that the holding parts 5 and 7 are not formed in two layers, but are only formed in one layer. As can also be seen, these single-layer panels are designed without a recess or cut-out. In this context, they are almost square, flat plates.

In this exemplary embodiment of the suspension device 1, a separate coupling part 15 is provided. Correspondingly, a further corresponding coupling part 22 is also provided here on the opposite side. This coupling part 22 is also designed separately from the central rail 2 . The coupling parts 15 and 22 are arranged directly on the holding parts 5 and 7 . The coupling parts 15 and 22 are made in particular from plastic. In particular, they are designed in one piece. In this exemplary embodiment, the coupling parts 15 and 22 are designed as external cover caps. This means that they almost completely cover the holding parts 5 and 7 on the outside. The holding parts 15 and 22 also have recesses 23 here. These recesses 23 form U-shaped geometries. These recesses 23 are in turn retaining cam receptacles for receiving a retaining cam of a household appliance component. Only in this area of the recess 23 is the holding part 5 not covered laterally by the coupling part 15 . The same is provided for the coupling part 22 with respect to the holding part 7 .

Provision can be made for a coupling part 15 to be attached directly to the holding part 5 . For example, a plug connection or a snap connection can be provided here. In addition to or instead of this, however, the coupling part 15 can be fastened to the end 4 of the suspension part 3 . For example, the coupling part 15 can have an insertion part here, which is inserted into an insertion holder of the suspension part 3 . This insertion holder can be designed in one piece with the suspension part 3 .

For example, the suspension part 3 can be designed as a profile rail. This means that in addition to a front panel 24 ( 6 ) backwards protruding hollow chambers 25 and 26 ( 7 ) having. These are also formed in one piece, produced in particular by bending, in particular roll-forming. These hollow chambers 25 and 26 , which are open laterally in the width direction, are designed to receive an insertion part of the coupling part 15 . A plug connection and/or a clamp connection can also be provided here. In particular, a positive or non-positive connection or insertion of the insertion part into these hollow chambers 25 and 26 is provided here.

As in 7 can be seen, the hollow chambers 25 and 26 are formed by bent material areas of the suspension part 3 . In the cross section perpendicular to the longitudinal axis 3, however, these hollow chambers 25 and 26 are not completely closed on the peripheral side. This also enables a certain deformation elasticity, in particular also for the non-positive insertion of the insertion part of the coupling part 15 . The same applies to the opposite side or to the opposite end 6 of the suspension part 3. A corresponding insertion part of the coupling part 22 can then also be inserted into the hollow chambers 25 and 26.

In 7 is the suspension device 1 according to 6 shown with the separate coupling part 15 removed.

In 8 another exemplary embodiment of a suspension device 1 is shown. Here the central rail 2 can in turn be designed with a strip-shaped suspension part 3 . Correspondingly as in 1 and 2 this suspension part 3 does not have to be designed as a profile rail, as is shown in 6 and 7 is preferably present. Rather, it can be a strip or plate layer that is simple in this respect. It can, as well as in 2 , Have a rearwardly oriented web 27 at a lower edge. This stabilizes the otherwise single-layer, flat panel with regard to the suspension part 3.

In particular, this web 27 can also be used in accordance with the exemplary embodiment 3 and 4 be provided.

The outer wall 30 has a recess 23 which is open at the bottom. This in turn is designed to accommodate a retaining cam. In particular, also as in the exemplary embodiment in 3 and 4 the coupling part 15 also serves as an edge protection element. This means that it covers the peripheral edge 17 and protects it in this respect. In this regard, the coupling parts 15 and 22 according to the exemplary embodiments in Figure 3, Figure 4 and figure 5 as 8 and 9 also designed as edge protection elements 32.

In particular, the coupling part 15 is formed such that the insertion slot 29 is open, in particular only upwards and at the rear vertical edge of the coupling part 15, so that the coupling part 15 can be attached to the holding part 5 from below.

In 10 a household appliance component 33 is shown in a perspective view. In particular, this is a household refrigeration appliance component. In particular, this is a door of a household refrigeration appliance. In particular, this household appliance component has an interior lining 34 . This is formed in one piece from plastic, for example. Vertically oriented struts 35 and 36 are formed protruding from this inner lining 34 . They are oriented parallel to each other. The hanging device 1 can be releasably attached to these bars 35 and also to a rear wall 40 of the interior paneling 34 without destroying it. So is in 10 a retaining cam 37 is shown as an example on an inside of the spar 36 . This retaining cam 37 is for direct engagement with the above explained recesses of the suspension devices 1, which then represent holding cam recordings formed. In addition, in 10 an exemplary embodiment of an arrangement 38 is also shown. The arrangement 38 has a hanging device 1 and at least one food storage container 39 separate therefrom. This is suspended in a cantilevered manner on the suspension device 1 , in particular suspended on the suspension part 3 of the central rail 2 . In the embodiment in 10 the holding parts 5 and 7 are formed according to an embodiment with two plate layers.
