Description

a) mit vorzugsweise mehreren parallel übereinander angeordneten, in eine Innenwand, insbesondere die Türinnenwand, eingeformten Führungsnuten,

b) die in der Art von Schwalbenschwänzen nach oben wie nach unten gerichtete Hinterschnittnuten aufweisen, welche an ihren Enden geschlossen sind,

c) und mit mindestens einer Kühlgutablage, die für den Eingriff in die Hinterschnittnuten angepaßte übereinander vorgesehene Rasthaken umfaßt.

The invention relates to a refrigerator

a) preferably with a plurality of guide grooves arranged in parallel one above the other and formed in an inner wall, in particular the door inner wall,

b) which have upward and downward undercut grooves in the manner of dovetails which are closed at their ends,

c) and with at least one refrigerated goods shelf, which comprises latching hooks which are provided one above the other and are adapted for engagement in the undercut grooves.

In a known cooling device of this type (DE-GM 77 27 326) the inner door wall with several parallel one above the other and horizontal guide grooves equipped, the at both ends in front of the relevant side edge of the inner door wall end and are completed.

The guide grooves point at predetermined intervals Undercuts that act as indentations in the deep-drawn guide grooves are formed. The Guide grooves are thus partially of the type of Swallowtails with both up and down Undercut grooves for the engagement of adapted locking hooks molded out the back of shell-like Chilled goods shelves with adapted to the undercut grooves Height distances are arranged.

The upward locking hook is rigid and to locking hooks engaging in the lower undercut groove below elastically deformable so that after hooking the top Locking hook in an upper undercut groove of the lower locking hook over a run-up slope as far as the upper locking hook is deflected that it over the lower undercut flank slides away and fall into the lower undercut groove can.

In practical operation, it turns out that in the Dimensional tolerances occurring in plastics processing are safer Engagement of this snap-lock connection is not guaranteed is. There is also the risk that the elastically deformable lower locking hook, the weight of the possibly loaded Chilled goods shelf must support, due to material fatigue is permanently bent upwards. This loses the Chilled goods storage their secure hold.

The invention has for its object in a cooling device measures according to the preamble of the first claim meet through which a reliable permanent bracket cooling goods storage in a guide groove is ensured and the insertion and removal without special Force can be performed.

According to the invention, this object is achieved by that the guide grooves along their length with undercut grooves are provided, of which, however, at least one Undercut flank via the associated locking hook corresponding width is omitted to the bottom, the locking hooks on the refrigerated goods shelf being rigid are.

In one embodiment of a cooling device according to the invention is made by shortening at least the flank of a lower one Undercut groove over a limited area created, the refrigerated goods shelf continues from the front insert into the relevant guide groove or guide grooves, whereby a locking connection is no longer overpressed is required. The undercut grooves extend over the entire remaining length of the guide grooves, so that the Latching hooks laterally after insertion in the open section in the uncut part of the undercut Guide grooves can be inserted. An end face Open the guide grooves through to the outside of the door sloping side edge of the inner door shell through that then can lead to a reduction in door stability not mandatory. In addition, they are up and down pointing locking hooks on the refrigerated goods shelf rigid, so that a deformation in operation that leads to a reduction in the secure bracket can be avoided.

The guide groove can be used at both ends for the frontal use of Chilled goods shelves should be open so that refrigerated goods shelves from opposite sides in guide grooves can be inserted. This is useful if one Chilled goods shelf in the height in the range of a another guide groove inserted cooling goods shelf is sufficient. The relevant refrigerated goods shelves can then be used without mutual influence from the associated guide groove be removed. Is only the lower undercut edge opened, when a refrigerated goods shelf is inserted, it is moved to hook directed upwards into the upper undercut groove at after Chilled goods shelf tilted at the top, then lowered the front edge of the refrigerated goods shelf also the lower locking hook in the guide groove is swung in.

Should prevent the refrigerated goods shelf from tipping up on one side then both the upper and the lower are expedient Undercut flank for the engagement of the associated locking hooks open. In this case it is advisable to use the different heights arranged in Direction of displacement to be offset from each other and also the open sections of the undercut flanks to move accordingly. It is also an advantage at least one of the guide grooves only from an edge region let the door wall extend over part of the wall width, to keep a wall area free of refrigerated goods shelves in the tall objects, such as bottles and the like, may protrude on one below the shortened guide grooves Chilled goods are to be put down.

The invention is based on the schematic diagrams of exemplary embodiments explained in more detail.

A door 1 of a cabinet-shaped cooling device, in particular a refrigerator consists of an outer door shell and one inner door shell 2 drawn or injection molded from plastic, the space between the outer shell and the inner shell is preferably foamed with thermal insulation. In the door inner wall surface 3 facing the cooling compartment is one Plurality of parallel one above the other in the horizontal direction extending guide grooves 4 formed in the manner of Swallowtails facing up and down Have undercut grooves 5.6. The guide grooves 4 end at a distance from the vertical to the outer door shell angled narrow edge strips 7 of the inner door shell 2, which is therefore not interrupted and is optimal Stability guaranteed. They are at their lateral ends Guide grooves 4 opened, including the top and bottom Undercut edge 8 or 9 of the undercut flanks 5.6 to are left out of the bottom. The top and the bottom The opening edge 10, 11 of this groove extension therefore has one Distance from each other, which is the distance between the bottom 12 or 13 of the upper and lower undercut groove corresponds.

On the guide grooves 4 are in particular cup or to set cup-shaped refrigerated goods racks, which at their the Door wall 3 facing rear wall 14.1 at least one upwards and have a downward locking hook 15, 16. The latching hook 15 bent upward in the operating position engages behind the upper falling rear flank 8 of the upper guide groove 5 and the locking hook bent downwards 16 the upward-running undercut flank 9 of the lower one Undercut groove 6. This is in the direction of displacement measured width of the locking hook 15.16 as large as that corresponding width between the opening edges 10, 11. in the The area for the chilled goods can thus be in the area of the opening edges 10, 11 14 with their locking hooks 15, 16 in a horizontal plane the area of the guide grooves 4 are used. By lateral displacement into the guide grooves 4 come then the locking hooks 15, 16 with the relevant flanks 8, 9 Associated guide grooves 4 in grip, so that Chilled goods shelf 14 against tipping over as against accidental Top swing is secured. The locking hooks 15, 16 are included trained as rigid elements and solely for the carrying and Dimensioned holding function.

The lowering of the undercut flanks 8.9 is at both ends of the relevant guide grooves 4 possible and easier Insertion of different heights in particular Refrigerated goods shelves 14 that are in the displacement path of another Chilled goods shelf 14 are sufficient. However, it is sufficient, too to provide an extension 10.11, in particular on a End of the relevant guide groove 4 is provided. Also it is sufficient if only the lower undercut edge 9 is lowered because then the upper one is tilted accordingly Snap hooks 15 are hooked into the upper undercut groove 5 can, while the lower locking hook 16 in the area of omitted lower undercut flank 9 in the area of Opening edge 11 can be pivoted into the guide groove 4 can. By moving the refrigerated goods shelf 14 laterally then again the locking engagement with the lower one Undercut flank 9 a.

1 and 3 are narrow in the vertical direction Guide grooves 4 formed. The height of the rear wall 14.1 and the height distance of the assigned latching hooks 15, 16 is so dimensioned that the locking hook 15,16 in different Engage the guide grooves 4. In the embodiment according to the 2 and 4 is the width of the guide groove 4 in the height direction dimensioned so that both locking hooks 15, 16 in the same Engage the guide groove 4. The distance between the respective reason 12 and 13 of this wide groove the distance between the bottom 11 of the upper groove and the bottom 12 of the the next lower groove of the embodiment according to FIG. 3 correspond. The refrigerated goods shelves 14 can therefore in both Versions are used unchanged.

To ensure that there is sufficient space for setting high refrigerated goods containers such as bottles or the like is, at least one guide groove 4.1 of one Edge area of the door wall 3 only over part of the Extend wall width, as shown in Fig. 2. The shortened Guide grooves 4.1 are in particular above the lowest refrigerated goods rack, in which usually bottles and the like.

It is also possible to have different heights arranged locking hooks 15, 16 also in the direction of displacement to be staggered. Then be useful too the assigned lowered sections 10, 11, in which the relevant undercut flanks 10, 11 are omitted, accordingly offset to the lowered areas as small as possible and the usable length of the guide grooves to keep as large as possible.
