Abstract

A household appliance, in particular a refrigerator or a freezer or a furniture item comprising at least one storage space, in which a support plate is positioned comprising a storage area and a shelf which can be rotationally and translationally moved on the storage area of the support plate, wherein: the shelf comprises a flat storage area which is oriented plane-parallel to the storage area of the support element; the shelf can be rotated relative to the support plate in a first rotational direction and can be displaced in a predefined direction; mutually facing bearing surfaces of the storage areas each have closed peripheral raceway grooves in which rolling elements are guided; the raceway grooves are formed such that, when a force is applied to the shelf in a direction defined in the plane of the storage area, the shelf can be moved, in a movement which is at least partially forcibly guided and which is simultaneously rotational and translational, from a base position into an intermediary position, the shelf being rotated relative to the support plate in one of two possible opposing rotational directions and being displaced in a predefined direction; and the shelf, after being moved into the intermediary position, can be further rotated relative to the support plate in the one of two possible opposing rotational directions and can be displaced counter to the predefined direction and, when rotated by 180°, resumes the base position.

First claim

The invention claimed is:

1. A household appliance or a furniture item having at least one storage space, in which at least one carrier plate having a bearing region and a shelf rotationally and translationally movable on the bearing region of the carrier plate are arranged, wherein the shelf has a planar bearing region, which is aligned plane-parallel to the bearing region of the carrier plate, wherein the shelf is rotatable in relation to the carrier plate in a first rotational direction and is displaceable in a predetermined direction, wherein bearing surfaces of the bearing regions facing toward one another each comprise at least one closed, peripheral running groove, in which roller bodies are guided, wherein the running grooves are formed in such a way that if a force acts on the shelf in a direction defined in the plane of the bearing region, the shelf is movable in an at least partially positively-guided, simultaneously rotational and translational movement from a base position into an intermediate position, during which the shelf is rotated in relation to the carrier plate in one of two possible opposing rotational directions and is displaced in a predetermined direction, wherein the shelf, after the movement into the intermediate position, is pivotable in relation to the carrier plate further in the one of two possible opposing rotational directions and is displaceable opposite to the predetermined direction and occupies the base position again upon a pivot by 180°.

2. The household appliance or furniture item according to claim 1 , wherein two closed, peripheral running grooves are introduced into one of the bearing regions and precisely one closed, peripheral running groove is introduced into the other of the bearing regions.

3. The household appliance or furniture item according to claim 1 , wherein the roller bodies are formed as balls.

4. The household appliance or furniture item according to claim 1 , wherein four roller bodies positioned spaced apart from one another are guided in the running grooves.

5. The household appliance or furniture item according to claim 1 , wherein the roller bodies are held in a roller body cage.

6. The household appliance or furniture item according to claim 1 , wherein the bearing regions are formed in one piece with the carrier plate or the shelf, respectively.

7. The household appliance or furniture item according to claim 1 , wherein at least one of the bearing regions is formed as a separate element, which is insertable into a correspondingly shaped receptacle in the carrier plate or the shelf or is attachable by connecting means to the carrier plate or the shelf, respectively.

8. The household appliance or furniture item according to claim 1 , wherein a guide is arranged in one of the bearing regions and a guiding and holding element is arranged in or on the other bearing region.

9. The household appliance or furniture item according to claim 1 , wherein the closed peripheral running grooves are each introduced around the center point of the bearing region of the shelf and the bearing region of the carrier plate up to a front edge of the carrier plate in the direction of the translational movement of the shelf.

10. The household appliance or furniture item according to claim 1 , wherein the closed peripheral running grooves have multiple catch points for the roller bodies in the base position, which are reached after each rotation of the shelf by 180°.

11. The household appliance or furniture item according to claim 1 , wherein the shelf does not protrude over a rear edge of the carrier plate opposite to the direction of the translational movement of the shelf during the entire movement.

12. The household appliance or furniture item according to claim 1 , wherein the carrier plate is installable recumbent or hanging or standing vertically in the storage space.

13. The household appliance or furniture item according to claim 1 , wherein the carrier plate is secured in the storage space or on a storage surface.

14. The household appliance or furniture item according to claim 1 , wherein the shelf has more than one bearing region and interacts with more than one carrier plate.

15. The household appliance or furniture body of claim 5 wherein the roller bodies are held captively in the roller body cage.

16. The household appliance or furniture body of claim 1 wherein the running grooves are not parallel to each other.
