Foam-tight is understood to denote a possibly existing gap between the component and the cutout of the outer skin as far as possible or even close, so that in a following assembly of the component in the neck following foaming, in which a gap between the inner container and Exterior skin is foamed with insulating material, leakage of liquid, not yet cured insulating foam is prevented.

By means of the holding ribs of the component and the adjacent free edges of the tabs on the one hand, falling out of the component from the cutout is prevented and on the other hand formed by the holding ribs a labyrinth gap, which prevents leakage of liquid insulating foam. An occurring obliquely concerns the Tabs on the holding ribs or on the component can cause the tabs are additionally pressed by the insulating foam against the component due to the foam pressure during foaming and thus the tightness is additionally increased. Due to the shape and arrangement of the tabs separate retaining clips can be omitted. Also, separate seals can be omitted.

The tabs can be formed by angled inner edge portions of the outer skin. The tabs can be formed in this respect of sections of the outer skin. For this purpose, an edge portion can be folded parallel to a longitudinal edge of the cutout. Thus, the tabs can be integrally formed with the outer skin.

The cutout may have a rectangular or square contour with four straight inner edges, each side of which has a tab. The tabs can be folded along a line running parallel to the inner edge. In each case two adjacent tabs in the plane of the cutout or the outer skin can be separated from each other by an incision.

The tabs may have a trapezoidal shape. The tabs may in particular have the shape of an isosceles trapezium. This trapezoidal shape of the tabs can be created, for example, in that a respective incision is made at an angle of 135 degrees with respect to the inner edge of the cutout on a rectangular or square cutout in the four corners, which extends up to a fold line extending to the inner edge. The fold line forms the base, i. the longer base of the trapezoid.

In all embodiments of the invention, the outer skin of a cardboard and / or cardboard-like wall can be formed. The outer skin can to this extent consist of pulp, paper, in particular waste paper-containing material and to this extent be prepared by gluing and / or -pressen. The cardboard and / or cardboard-like wall can have almost any thickness. The outer skin may have a basis weight of less than, but also more than 600 grams per square meter. The cardboard and / or cardboard-like wall can be provided with a heat-ray reflecting layer, in particular with an aluminum foil or aluminum lamination.

The cutout can be made by punching out a cardboard and / or card-like sheet and / or the tabs can be separated from each other by cutting the cardboard and / or card-shaped sheet. The cutout can be produced at the same time as a drop and / or outside contour finishing of an outer skin component.

The tabs may have base edges that may be made by embossing the carton and / or card-shaped sheet to form creases and / or film hinge-like thinning. These fold lines run along the base, i. along the longer base of the trapezoid.

In all embodiments of the invention, the component may be a handle, in particular transport handle, or a receptacle, in particular a housing for receiving electrical and / or electronic components, in particular electronic boards for controlling the refrigeration device. The component, in particular the transport handle or the receptacle can be made as a plastic injection molded part. On a refrigeration device, the components can be preferably mounted in pairs in the form of transport handles. In each case two transport handles can be arranged for example on a rear wall and / or a bottom wall of the refrigerator.

The component can thus be kept free of adhesive in the cutout of the outer skin or of the carton and / or cardboard-like arc by means of the tabs lying on the retaining ribs.

The component can thus also be kept free of separate sealing devices in the cutout of the outer skin or of the cardboard and / or cardboard-like bow by means of the tabs resting on the retaining ribs.

In summary, and with differently shown under the invention, inter alia, a foam-tight locking of a component, in particular a carrying handle in a backboard and / or bottom board of a refrigerator result.

The back of a refrigerator is often represented by a cardboard, the so-called back wall board. In this backboard sometimes components, such as For example, transport handles or electronic boxes are used. Refrigerators can be equipped with transport handles, for example. The handles are pasted in with much effort. The invention may provide a better solution for mounting the handles. So far, the carrying handles are glued into the back wall board and floor board with hot glue. This process is time consuming and expensive. In addition, the tightness of this adhesive connection depends on the care during assembly. Bad adhesion can lead to foaming, ie leaks. This in turn leads to an expensive rework and / or cleaning of the refrigerator.

In other cases, e.g. Electronics housing inserted into the rear wall board. These are inserted into a hole in the cardboard and sealed with adhesive tape.

According to the invention, a possibility is to be created in which, for example, components can be used in the back wall or bottom board. With the embodiments according to the invention, for example, a bond can be omitted. It is created a simple rest solution. The design is particularly foam-tight, it is usually no additional sealing effort needed. It can be a simple and error-free installation.

Instead of a simple punching in the cardboard, the cardboard can be cut so that, for example, four tabs. The handle according to the invention has ribs. The paperbags snap into place behind these retaining ribs and at the same time seal a gap between the component and the cardboard.

In addition to the described handle attachment in the back board, the same system can also be used for handles in the floor area or for electronics housings in the cardboard.

It can be done faster assembly by latching instead of gluing. The assembly process can be done faster and easier from just one page. A gluing process would be tied to a specific workplace. The snap-in can be carried out on a wide variety of workstations. This allows better utilization of the assembly line.

By springing back the cardboard straps, the component engages and seals at the same time. The component can be designed symmetrically so that it can not be mounted incorrectly. It is a quick and easy installation possible.

Further features and advantages of the invention will become apparent from the following description of an exemplary embodiment with reference to the accompanying figures. Concrete features of this embodiment may represent general features of the invention.

The Fig. 1 shows as an example of a refrigerator, a household refrigerator 1 in the design of a Kühlgefrierkombination. The household refrigerator 1 has at least one heat-insulated inner container 2, in the illustrated embodiment of Fig. 2 two heat-insulated inner container 2a, 2b. An upper heat-insulated inner container 2a forms a cooling space as a cold room for storing refrigerated goods above zero degrees Celsius, in particular between zero degrees and plus eight degrees Celsius. The upper heat-insulated inner container 2a is closed by a first door leaf 4a. A lower heat-insulated inner container 2b forms a freezer compartment as a cold room for storing refrigerated goods below zero degrees Celsius, especially at about minus 18 degrees Celsius. The lower heat-insulated inner container 2b is closed by a second door leaf 4b. On a rear side of the household refrigerating appliance 1, a rear wall board 5a is attached. On an outer side of the rear wall board 5a, a condenser 6 of a refrigeration cycle is arranged, which is connected to a compressor 7. The rear wall board 5a forms a concrete embodiment of an outer skin 5 of the household refrigerator 1. At an upper end portion of the outer skin 5 and the rear wall board 5a, two transport handles 7a, 7b are fixed as components 7.

The Fig. 2 shows the example of the upper heat-insulated inner container 2a of the cooling space of the Kühlgefrierkombination Fig. 1 the arrangement of the inner container 2 a and the outer skin 5 partially surrounding the inner container 2 a and the rear wall board 5 a, which is arranged at a distance from the inner container 2 a, to form a gap space 8, which is auszuschäumen with heat-insulating material.

In the Fig. 3a an enlarged portion of the household refrigerating appliance 1 is shown in a section through one of the two transport handles 7a, 7b. In a mounting position, as in Fig. 3a shown assembly position, the component 7 in a section 9 ( Fig. 3b ) used.

The section 9 is in the Fig. 3b above and Fig. 4a shown closer. The outer skin 5 has tabs 11 distributed along its cutout contour 10. The tabs 11 each have a free edge 12. The tabs 11 are formed in the illustrated embodiment of angled inner edge portions of the outer skin 5. The cutout 9 has a rectangular contour with four straight inner edges 10a, 10b, 10c, 10d, each side of which forms a tab 11. The tabs 11 have a trapezoidal shape.

The flaps 11 can be folded over along fold lines 13a, 13b, 13c, 13d running parallel to the inner edges 10a, 10b, 10c, 10d, as shown in FIGS Fig. 4a and 4b is shown. Two tabs 11 lying next to each other in the plane of the cutout 9 or the outer skin 5 can be separated from one another by an incision 20.

The tabs 11 may in particular have the shape of an isosceles trapezium. This trapezoidal shape of the tabs 11 can be created, for example, that at the cutout 9 in each of the four corners, an incision 20 at an angle of 135 degrees with respect to the inner edges 10a, 10b, 10c, 10d of the section 9 is introduced, the up to the fold line 13a, 13b, 13c, 13d extends. The fold line 13a, 13b, 13c, 13d forms the base, i. the longer base of the trapezoid. The fold line 13a, 13b, 13c, 13d thereby form the bending edges and / or film-hinge-like thinning, which can be produced by embossing the cardboard and / or card-like sheet 5a.

As in Fig. 3b shown, the component 7, 7a, 7b to the free edges 12 of the tabs 11 corresponding retaining ribs 14, where the free edges 12 of the tabs 11 in the mounting position, as in Fig. 6b and Fig. 7 shown, lock in place.

In Fig. 5a to Fig. 6b a sequence is shown, in which the component 7, 7a, 7b is successively inserted into the cutout 9 of the outer skin 5, or the rear wall board 5a. Next pierces, as in Fig. 5a indicated, a dome-shaped bottom portion 15 of the component 7, the neckline 9. In this case, the tabs along their fold lines 13a, 13b, 13c, 13d are bent by the dome-shaped bottom portion 15. The free edges 12 of the tabs 11 slide along the side walls 16 of the component 7 down.

In an intermediate position according to Fig. 5b the tabs 11 slide over the projecting retaining ribs 14 of the component 7 away. The tabs 11 are bent further elastic.

In a situation according to Fig. 6a stand the free edges 12 of the tabs 11 just before jumping off from the projecting retaining ribs 14, ie inwardly collapse on the side walls 16 of the component 7 due to the internal elasticity again. In the final mounting position of the component 7, the tabs 11 are elastically folded under the projecting retaining ribs 14 of the component 7. The free edges 12 of the tabs 11 are flush against the undersides of the projecting retaining ribs 14 of the component 7. This final assembly position of the component 7, or the transport handle 7a, 7b in the cutout 9 of the outer skin 5 or rear wall board 5a is in Fig. 7 shown again in a perspective view.
