Description

The invention relates to a household refrigerator with an interior to be cooled with a rear wall and two side inner walls, which can be closed with a door. Refrigerators have pull-out trays or shelves for storing refrigerated goods. In order to meet the individual wishes of the user these are adjustable to different heights or can be arranged. Pull-out trays or shelves can be pulled out of the interior of the refrigerator for easier access to refrigerated goods.

DE 9314675 U1 shows a refrigerator whose shelves are extendable and adjustable in height. This takes place in that two vertical rails parallel to each other and to the opening side of the refrigerator door are arranged on the side walls of the refrigerator compartment, which are provided at intervals with latching recess and in which latchable and releasable holding pieces are displaceably guided. The holding pieces are provided on their sides facing each other with guide pieces which engage in the storage shelves and thus allow height adjustment along the rails. The shelves have grooves into which the guide pieces engage and extending along these grooves according to their length is possible. DE 9314675 U1 discloses a household refrigerator according to the preamble of claim 1.

US 2,299,512 A discloses a refrigerator with a movable shelf having channels laterally. In the channels supports are added, which are attached to the container sides. The shelf can thus be pulled out or inserted. DE 103 39 935 A1 discloses a refrigerator comprising a body and a door which define a heat-insulated interior, and a slide-out from the interior with the door open pulled out refrigerated goods. From the body and refrigerated goods, the one has a laterally open groove with mutually facing lower and upper sides and the other two spaced from each other in the groove engaging wheels, the peripheral surface of each of the lower and upper sides touching rolling.

DE 10 2008 019 417 A1 discloses a refrigerator with a heat-insulated housing having an outer casing, a heat insulating layer and a container walls Inner container having an interior for receiving refrigerated goods, wherein on one of the container walls a pull-out rail is arranged with a fixed rail part and a Lösschienenteil, which serves for securing a pull-out refrigerated goods storage. The fixed rail part is provided with openings which are provided on the container wall provided fasteners with clearance, of which at least one is connected by a locking member without play in the direction of movement of the Lösschienenteils with a Festschienentel.

JP 7-91821 discloses a drawer with laterally mounted pins. The pins engage in horizontal grooves, with several of these horizontal grooves being superimposed. Via a rotatable element which can receive the pins, the pins can be inserted from one groove into another groove.

Such an adjustment is very cumbersome in its handling, since on the one hand the extract is limited to the possible groove lengths and on the other hand, the height adjustment on the side rails only with a certain effort and fingertip feeling is possible.

It is therefore an object of the invention to provide an adjustment system for storage plates and pull-out trays, which allows a simple adjustment of the position and overcomes the disadvantages of the prior art.

To solve this problem, the invention proposes a household refrigerator according to claim 1.

The domestic refrigerator according to the invention has an interior to be cooled with a rear wall and two side inner walls, which can be closed with a door. At least two cams are provided on each side wall. These are arranged substantially horizontally relative to one another and communicate with at least one corresponding lateral holding element for a plate or a container. These engage in a corresponding guide of the lateral support member, which is aligned horizontally and vertically and over which the plate or the container is arranged horizontally and vertically movable.

The cams are at least substantially horizontal to each other, d. H. that they are about the same height. Thus, they can engage in the guide of the lateral support member and hold the plate or the container in the desired position, wherein the plate or the container via the cams is horizontally and vertically movable.

A plate or a container may be, for example, a shelf made of plastic, glass or a grid, as well as an extract tray, which may have different depths. The lateral holding element may be part of a plate or a container. It may also be part of a frame or a lateral rail which is arranged on the plate or the container. The guide of the lateral support member is determined by its shape and may be in the horizontal orientation, for example, a groove or a rail. Due to this simple structure, the cooling interior cam, which are arranged approximately at the same height, defined at Make or at defined intervals and only by the interaction with the corresponding guide height adjustment or an excerpt of the plate or container is possible. By "cam" is meant a projection which is preferably not equipped with a guide wheel or the like and z. B. has an approximately cylindrical shape. This simple structure is comfortable and inexpensive to manufacture. The susceptibility to error of this structure is also low, since here are few elements related to each other.

Preferably, at least one wall element which has a substantially horizontal orientation is arranged for each side inner wall. The wall element has the at least two cams, which in a corresponding guidance of the lateral Grab holding element. About this horizontal arrangement, the plate or the container is arranged horizontally and vertically movable. The wall element is oriented horizontally, that is, it runs along a plane parallel to the bottom surface. The cams are therefore arranged one behind the other in approximately the same height. Thus, it is possible to arrange a plurality of wall elements at different heights, which can each accommodate a plate or a container. Preferably, the wall element is a molded part which can be inserted into the side inner wall. Thus, it is easy to manufacture and easy to handle. In addition, the attachment is reliable and robust.

According to a special embodiment, the cams are formed from the respective side inner wall. Preferably, the cams are already formed in the manufacturing process of the so-called "inner liner" of the household refrigerating appliance by deep drawing from the side inner walls. This allows a cost effective and very simple method of production.

According to a preferred embodiment, on each side inner wall, in each case three cams, which are arranged substantially horizontally to one another, are provided. This means that three cams can be provided at approximately the same height. However, several sets of 2 or 3 cams, which are each arranged at a different height can be provided on a side inner wall. Three cams allow a very reliable arrangement of a plate or a container, wherein the extract can follow beyond the rearmost cam, since the two front cams can absorb the forces on the extended plate or the extended container satisfactorily. The cams can be formed both from the side inner wall, as well as be assigned to the wall element.

According to the invention, the guide in the lateral holding element has at least two essentially vertical grooves which are respectively guided along at least one cam for height adjustment of the plate or container. The vertical guide thus takes place via grooves which are arranged in the holding element. Thus, it is possible for a user, the plate or the container by simply raising or lowering the plate or the To adjust container in the interior space of the household appliance. It is not necessary to operate additional control elements or to lift the plate or the container out of the cams.

According to the invention, at least two substantially horizontal recesses branch off from the at least two substantially vertical grooves, which recesses are arranged on the cams in order to serve as a stop for the plate or the container in one of a plurality of vertical positions. Thus, it is possible to hold a plate or a container in a vertical position, wherein it is conceivable that the groove has a plurality of horizontal recesses and thus the lateral holding element has a plurality of parking positions to the plate or the container at different heights place. Thus, the height adjustment of the plate or the container is very easy to handle implemented with simple means and designed very variable.

Preferably, the cam lying closest to the rear wall has a smaller cross-sectional area or a smaller diameter than the at least one further cam. This offers the possibility that the recesses or the grooves on the lateral holding element have individual regions for each cam and thus prevents the container or the plate from being arranged in a wrong position on the cam. In addition, it is possible to assign different functions to the recesses or grooves which are adapted to the different sizes of the cams.

Particularly preferably, the horizontal movement of the plate or of the container takes place from the interior of the household refrigerating appliance along the cams via at least one substantially horizontal groove. Such an extract is very simple, thus very easy to manufacture and in its handling. A horizontal groove means that the cam is guided in a recess which has at least one closed upper edge.

Preferably, the at least one substantially horizontal groove tapers in a rear region, ie the region which is closest to the rear wall of the refrigeration device. The taper prevents slipping of the plate or the container of all cams and thus serves as a stop for at least one cam.

According to one embodiment, the rearmost, smaller cam can be guided by the taper of the groove and the taper serve as a stop for the following cam. In this case, an extract is made possible, which goes beyond the rearmost cam and thus takes place far out of the interior of the household refrigerator. This is particularly advantageous for the user, since the plate or the container is exposed and the refrigerated goods are easily accessible.

Advantageously, the at least one substantially horizontal groove on the bottom side openings, which allows insertion into the groove by placing the plate or container on the cam. This is a special embodiment, for example, if the groove is tapered in a rear area and thus a sliding from the front is not possible, so a placement from above on the cam is necessary. However, this can also be done independently of a taper, since a placement of the plate or the container from the top of the cam for a user is advantageous because it is much easier than a push from the front.

According to another embodiment, the lateral retaining element both at least one substantially horizontal and at least one substantially vertical groove for height adjustment and the extension of the plate or the container. Such a combination of both processes creates a very variable adjustment system, which is easy to handle, since the user only needs to grasp the plate or the container from the front and lift or pull in the appropriate position. In addition, this adjustment is less susceptible to interference, since it has very few items.

For example, the lateral holding element of the plate or of the container is raised at least in its side regions with respect to a shelf of the plate or of the container. It is thus conceivable that a plate or a container has a lateral holding element, which protrudes far beyond the edge of the plate or the container due to its adjustment, wherein the lateral holding member may extend both upwards and downwards. However, it is also possible for the plate or the container to have a frame which extends beyond the side facing the refrigerator interior door or the rear wall and thus forms a shell or at least a border.

This is done here via cams 2, 2 ', which are fastened to a wall element 3, wherein the wall element 3 is placed on the side inner wall 11. This wall element 3 has three cams 2, 2 '. The cam 2 'located closest to the rear wall 14 is significantly smaller in diameter and in particular in its vertical extent than the two further cams 2. A further storage plate 4 can be arranged on these cams 2, 2'.

FIG. 2 shows a perspective schematic view of an embodiment of a storage plate 4 with lateral support members 5 and two wall elements 3 with cams 2, 2 ', which should engage in the lateral support member 5. The lateral support members 5 are z. B. plastic strips which are molded laterally on the glass shelf 4. The wall element 3 has in each case three cams 2, wherein the rearmost cam 2 'has a smaller cross-sectional area than the two further cams 2. The wall element 3 also has two male elements 15, which are for inserting the wall element 3 in a side inner wall 11 of the household refrigerating appliance, not shown 1 serve. The cams 2, 2 'engage in the groove 6 of the lateral holding element 5. In the installed state, the tray can be placed from above on the cams 2, 2'. Here, the cams 2, 2 'are introduced via bottom-side openings 8 in the groove 6. About the groove 6, the tray 4 can be pulled out of the cooling interior. In this case, the lateral holding element 5 is moved with the tray 4 along the cam 2. In the rear region of the lateral holding element 5, the groove tapers 6. Here, the groove 6 has a taper 7. Due to this taper 7, the smaller cam 2 'still does not fit the next lying cam 2. Thus, the tray 4 can be pulled out so far that the groove 6 no longer engages in the small cam 2' and the closest cam 2 abuts against the taper 7 , Since the wall element 3 has a total of three cams 2, 2 ', the tray 4 also holds securely on the two front cams. It is also conceivable to arrange 4 or 5 cams and thereby provide several small cams, which can run through a taper to ensure a more stable guidance in very deep refrigerators or heavy plates.

FIG. 3 shows a schematic side view of the embodiment of a storage plate 4 with a lateral support member 5 according to Fig. 2 , The lateral holding element 5 has a groove 6 with a taper 7, in which case the cams 2, 2 'are in communication with the groove.

The plate 4 can still be extended until the nearest cam 2 has arrived at the taper 7 and strikes there because of its size. The lateral retaining element can thus be extended beyond the smaller cam 2 '.

FIG. 4 shows a schematic perspective view of another embodiment of a storage plate 4 with a lateral support member 5 which is formed here as a frame. The storage plate 4 is height adjustable here in two positions. This is done via a vertical groove 9 in the lateral holding element 5. The cams 2, 2 'engage in the vertical groove 9. The positions at different heights can be determined by stops 10. In a detected position, the cams 2, 2 'engage in one of the two stops 10 of the vertical groove 9. It is conceivable to provide even more stops 10 for further height adjustments between these two height settings.

FIG. 5 schematically shows a side view of a lateral support member 5 according to a specific embodiment. Based on this lateral support member 5, an adjustment can be made both in the vertical direction and in the horizontal direction. The horizontal grooves 6 taper in a rear region and each have a taper 7. The lower horizontal groove 6 has openings 8, through which a storage plate or container on which this lateral holding element 5 is arranged, on the cam 2, 2 'can be placed. As shown in the previous embodiments, a horizontal groove 6 can be pushed over the smaller cam 2 ', wherein the taper 7 forms a stop for the nearest cam 2. In this embodiment, in such an extended position, a height adjustment via the vertical grooves 9 take place. Thus, a plate 4 or a container can be extended in two different heights on such a lateral support member 5. It is conceivable to provide a similar lateral retaining element 5, which allows a plurality of height settings, in each of which the plate 4 can be extended. In addition, the invention is not limited to that the height adjustment must be made in the extended position.
