Definitions

• the present invention relates to a refrigerated goods container for a refrigerator and a refrigerator equipped with such a container.
• Refrigerated goods containers in particular for household refrigeration devices such as refrigerators and freezers, are often made in one piece from plastic flat material by molding.
• a draft angle i.e. the walls are not exactly parallel, but show a slight divergence towards the open front of the refrigerated goods container.
• pull-outs are installed in such a refrigerated goods container, the non-parallelism of the side walls leads to problems.
• Guide rails mounted on the side walls should not only allow movement of an extension guided in the rails in the longitudinal direction of the rails, but also to a lesser extent transversely to them. The guide play required for this, however, prevents the rails from being guided precisely and smoothly.
• the side walls of the refrigerated goods container in areas where a pull-out is to be installed are provided with a so-called 0 ° draft angle in conventional refrigeration appliances. That in this area the side walls run exactly parallel.
• the object is achieved by a refrigerated goods container according to claim 1 and a refrigeration device according to claim 9.
• the two guide rails of a pair of rails which are required for guiding a refrigerated goods container at least one is mounted on one of the side walls via a compensating element at an acute angle to the side wall, which compensates for and thus defines the divergence of the side walls is that the pair's rails are parallel.
• Both rails of a pair preferably have compensating elements which are mirror-symmetrical to one another, so that each compensating element compensates for half of the divergence angle.
• the compensating element is preferably formed in one piece on the rail. This requires only little additional effort in the manufacture of the rails, and the rails can be mounted on a side wall in the same way as in the conventional manner on walls with a 0 ° draft angle.
• the compensating element can in particular have the shape of a wedge which extends essentially over the entire length of the rail; But it is also conceivable to design it as a local projection near one end of the rail.
• the rail can expediently have a C-shaped cross section with an upper and a lower leg and a middle piece connecting the legs; such a rail shape is particularly suitable for roller guides.
• the compensating element is preferably formed in the middle piece by stamping.
• FIG. 1 shows a refrigeration device according to the invention in partial section
• FIG. 2 shows a side view of a guide rail to be mounted on a side wall of the refrigerated goods container of the refrigeration device from FIG. 1 and a guide rail which is complementary thereto and is to be mounted on a pull-out pull-out;
• FIG. 1 shows a refrigeration device according to the invention in partial section
• FIG. 2 shows a side view of a guide rail to be mounted on a side wall of the refrigerated goods container of the refrigeration device from FIG. 1 and a guide rail which is complementary thereto and is to be mounted on a pull-out pull-out
• FIG. 1 shows a refrigeration device according to the invention in partial section
• FIG. 2 shows a side view of a guide rail to be mounted on a side wall of the refrigerated goods container of the refrigeration device from FIG. 1 and a guide rail which is complementary thereto and is to be mounted on a pull-out pull-out;
• FIG. 1 shows a refrigeration device according to the invention
• FIG. 3 shows a plan view of the guide rail and guided rail from FIG. 2 in the assembled state
• Figs. 4 and 5 each show a section through the guide rail and the guided rail along the lines IV-IV and V-V from FIG. 3;
• Fig. 6 is a plan view of a guide rail and a guided rail according to a second embodiment of the invention.
• Fig. 1 shows in section the lower area of a refrigerator, which is e.g. can be a freezer compartment or a cellar compartment of a combination refrigerator.
• the refrigeration device comprises a heat-insulating housing 1 with an open front side that can be closed by a door 2.
• the housing is constructed from a refrigerated goods container 3 drawn in one piece from plastic, which forms the inner wall of the cooling space, a heat-insulating layer 4 made of foam material, and an outer shell 5 made of sheet metal. Due to the manufacturing technology of the refrigerated goods container 3, its wall surfaces, i.e. Ceiling 6 and floor 7 or the side walls 8, slightly divergent towards the front of the housing or the door 2 at an angle of 1 to 2 °.
• a total of three sets of guide rails 9 are mounted opposite one another at different heights on the side walls 8 and cooperate with complementary guided rails 10, which are each mounted on pull-out boxes 11, so that they can be conveniently pulled out or pushed into the refrigerated goods container 3 can.
• the side walls 8 are rib-free, this allows the mounting of the guide rails 9 at any height on the side wall.
• a single model of refrigerated goods container can therefore be used in a plurality of refrigeration appliance models that have different compartments or extracts of different numbers and / or sizes.
• a guide rail 9 and the associated guide rail 10 of the pull-out box 11 are separated from one another in side views in FIG. 2, in FIG. 3 in a plan view in the assembled state and in FIGS. 4, 5 each shown in section along the lines IV-IV and VV from FIG. 3.
• Both rails 9, 10 are elongated profile parts made of metal with a substantially C-shaped cross section with an upper leg 12, 13, a lower leg 14, 15 and a middle piece 16, 17 connecting the legs.
• the middle piece 17 of the guide rail 9 is attached its end facing the door 2 a roller 18 which supports the upper leg 12 of the guided rail in the assembled state;
• the guided rail 10 carries at the end of its center piece 16 facing away from the door 2 a roller 19 which, depending on how far the pull-out box 11 on which the rail 10 is mounted, extends either on the lower leg 15 or is supported under the upper leg 13 of the guide rail 9.
• a U-shaped channel 20 is formed in the center piece 17 of the guide rail 9, the depth of which, as can be seen from the two cuts 4 and 5, increases from the end 21 of the guide rail 9 remote from the door to the end 22 near the door.
• This channel 20 forms a compensating element, the increase in depth over the length of the guide ⁇ rail compensates for the divergence of the side walls 8 of the refrigerated goods container 3 and ensures an exactly parallel orientation of the legs 13, 15 of two opposite guide rails 9 assigned to the same extract.
• FIG. 6 shows a plan view of an arrangement of guide rail and guided rail according to a second embodiment of the invention.
• the guided rail 10 is identical to that shown in Fig. 2; the cross-sections along lines IV-IV and V-V are the same as in the previously described embodiment.
• the difference is 6 that the compensating element is not formed by a channel with a progressively increasing depth from one end of the guide rail to the other, but that the depth of the channel 20 remains the same over most of the length of the guide rail 9 as in FIG.
• a local projection 25 is formed only in the region of the end 22 near the door, the outer wall of which faces the side wall 8 and carries the vertical fastening hook 24 a greater distance from the legs 13, 15 of the guide rail that guide the roller 19 of the guided rail 10 9 has as the outer surface in the vicinity of the horizontal hook 23.
• the compensating element does not necessarily have to be in one piece with the guide rail, such as the channel 20 or the projection 25; instead, a compensation body attached to the guide rail could be used, which comes to rest between the guide rail and the side wall after assembly.
• a compensation element could also be subsequently inserted between the provisionally mounted guide rail and the side wall in the region of the hook 24 near the door, in order in this way to firmly clamp the side wall between the hook 24 passing through an opening in the wall and the compensation element.
