Definitions

• the invention relates to a household refrigerator with at least one receiving space for goods to be cooled according to the preamble of claim 1.
• the retaining part on the one hand over the edge region of the opening structure engages behind and thereby each other "back to back" oppositely oriented hooks to ensure that thereby a tensile force acts outward towards the wall, and on the other hand, the holding part via spring force with a Force component in the receiving space against the pulling direction of the hook parts to apply force to achieve in this way a play-free clamping support of the holding part in the wall.
• wall thicknesses of about 0.8 millimeters can be adjacent to those of about 2.2 millimeters over a few centimeters . It is often difficult or because of this it is not possible at all to have the holding part, which engages in the opening structure via a first hook, engage with an opposite catch hook behind the edge of the wall and thus secure it.
• the latching hook can not compensate for the tolerances, since it is optimized with its fixed latching projection to a defined thickness.
• the holding part is then not used sufficiently close to the wall in order to achieve a gap-free system can.
• the invention is based on the problem of improving the support of a holding part in a wall of the receiving space in a household refrigeration appliance.
• the invention solves this problem by a household refrigerator with the features of
• both hook parts can vary with respect to their depth of penetration against each other and thus compensate for different strengths of the walls.
• Under walls are understood not only lateral walls, but also a top, back or bottom of the receiving space. The hook parts can therefore reliably hold the holding part mechanically, without the need for gluing - neither with adhesive tape nor with spray adhesive - or similar further measures would be required.
• Such a holding part can then be used in an advantageous manner with an insertion direction perpendicular and in a direction parallel to the wall in the opening structure, Preferably, until an abutment arranged on the holding part comes into engagement with the opening structure and thereby blocks retraction of the holding part against the orientation of the engagement surfaces. Then, a reliable safeguard against longitudinal displacement of the holding part is achieved, wherein at the same time by the inclination of the rear engagement surfaces and a vertical insert wall for each particular pull-out is achieved.
• the at least two hook parts and an advantageous embodiment can have a large distance from each other in the longitudinal direction of the holding part and thereby enable a reliable hold of the holding part over its entire extent. It is advantageous if the opening structure of the wall a plurality of insertion openings for the hook parts of the holding part with a Wandungssteg therebetween, which can be engaged behind by a hook part, and also the abutment on these the insertion openings delimiting Wandungssteg is supported.
• the rear gripping surfaces can advantageously be formed as Abgleitschrägen for the edge region of the opening (s).
• a reliable mounting of the hook parts can be achieved, in particular, if the sliding slopes extend over at least five millimeters, in particular at least ten millimeters, along the wall.
• the holding part is advantageously provided with at least one spring clip which acts in the direction of the receiving space and which can be deformed in different degrees of deformation depending on the wall thickness, a high holding force can be applied in the direction of the receiving space.
• the spring clip may be formed circumferentially and simultaneously sealing.
• it can also be provided a separate circumferential seal, which is also advantageous depending on the wall thickness deformable in different degrees of deformation and thus can form a tolerance compensation for the different wall thicknesses.
• the outer seal may have a rubber elasticity in deviation from the body, such as by having a reduced material thickness and / or a different material relative to a body of the holding member, and thereby also allow the spring action and at the same time the behind the wall lying insulation region of the receiving space Shield over the gasket. The one-piece can still be maintained.
• the seal can advantageously be formed from a thermoplastic material and thus be injection-molded onto a body holding the seal 'of the holding part. This can form a dimensionally stable subunit of a likewise thermoplastic plastic.
• the assembly can also be done manually with just a handle, in particular the striking of the abutment is acoustically perceptible as confirmation of the correct seat.

• the receiving space AR is marginally limited to the sides and to the rear and above and below of walls W of a generally deep-drawn plastic part, wherein the
• Walls W of this molding can be provided with through structures D, as can be seen for example in the schematically drawn out receiving space AR of Figure 2.
• the narrow space between the walls W and an outer housing G of the household refrigerating appliance HK is usually filled with an insulating material, such as a foam, completely or at least for the most part.
• HT latching used - for example, as shown here, from the outside - in the assembled state in the receiving space AR protrude and in particular a temperature sensor, a
• a support of other parts, such as shelves, by such holding parts HT is possible.
• a - as shown here - or a plurality of opening structure (s) D can be provided.
• the or each holding part HT engages behind the wall W in the edge region of an opening structure D with at least two hook parts H1, H2 here from outside to inside.
• the holding part HT can be subjected to force by spring force F with a force component counter to the pulling direction of the hook parts H1; H2, so that a clamping holder of the holding part HT which is free of play with respect to a perpendicular direction to the wall W can be reached.
• at least two hook parts 1-11, 1-12 are provided with rear engagement surfaces HF oriented in the same direction with respect to the extent of the surface of the wall W for engaging behind the wall W.
• the holding part HT is provided with an abutment WL, which is so securable in the opening structure D that retraction of the holding part HT is blocked against the orientation of the rear engagement surfaces HF along the wall.
• the abutment WL In order to enable this opposite support on the one hand the hook parts H1, H2 and on the other hand, the abutment WL, the opening structure D for the hook parts H1, H2 of the holding part HT a plurality of insertion openings D1, D2, which are separated by a delimiting wall web WS.
• the abutment WL which can be formed by a simple stage without engaging latching projection, supportable.
• Different wall thicknesses at the insert openings D1, D2 of the two hook parts H1, H2 can be easily compensated with different depth of use, when the rear engagement surfaces HF are formed as Abgleitschrägen for engaging behind the edge region of the insertion openings D1, D2. These may have a large width of, for example, more than one centimeter and thus be stable and have a good handling during assembly.
• the Abgleitschrägen over at least five millimeters, better ten or fifteen millimeters, along the wall W extend. Also perpendicular to the wall W the Abgleitschrägen can extend over at least five millimeters, in particular ten or fifteen millimeters, perpendicular to the wall W, so as to allow tolerance compensation with respect to the wall thickness.
• a lying in the mounted position at the height of the wall W neck portion of the hook parts H1, H2 can be made thin and thereby be provided with a certain elasticity and flexibility.
• the holding part H is provided with at least one in the direction of the wall W effective spring clip F, which is deformable depending on the wall thickness in different degrees of deformation and thereby can compensate for the variations in the wall thickness.
