Shelf unit and shelving system

1. A shelf assembly for displaying products including a plurality of vertically arranged gravity feeding shelf units, each of said shelf units comprising:

a bracket;

a shelf configured to support a plurality of products to be displayed having a front side and an opposite rear side,

wherein said shelf, in a display position facing a forward direction when products placed on said shelf are accessible via said front side of said shelf, is arranged having an inclination angle for providing gravity feeding of said products in said forward direction, and

wherein said shelf is rotatably engaged with said bracket to be rotatable about an axis of rotation between said display position and a refill position of said shelf when said rear side is facing said forward direction, wherein a position of the axis of rotation with reference to the bracket is fixed; and

a tilting device engaged with said bracket arranged for providing tilting of a plane of rotation of said shelf during rotation of said shelf relative to said bracket between said display position and said refill position,

wherein said tilting device is configured to provide tilting of the plane of rotation of the shelf during rotation so as to control the inclination angle of the shelf, and

wherein a direction and an amplitude of said tilting during rotation of said shelf between said display position and said refill position, is selected to provide a set inclination angle of said shelf in said refill position.

2. The shelf unit according to claim 1 , wherein said set inclination angle in the refill position is zero degrees, so as to level said shelf.

3. The shelf unit according to claim 1 , wherein said inclination angle in the display position is at least partly provided by said tilting device.

4. The shelf unit according to claim 1 , wherein said tilting device is arranged on said bracket, and is a rotatable inclined bracket element having a set bracket angle, wherein said tilting of said plane of rotation is determined by said bracket angle.

5. The shelf unit according to claim 1 , wherein said tilting device is arranged as a rail whose vertical profile includes a height difference along an extension of the rail, and a corresponding tracking device arranged for running along said rail, said rail being arranged on said shelf, and said corresponding tracking device being arranged on said bracket, or vice versa.

6. The shelf unit according to claim 5 , wherein said tracking device is at least one roller element.

7. The shelf unit according to claim 5 , wherein said rail runs along at least part of a circular path.

8. The shelf unit according to claim 5 , wherein said height difference of the rail is proportional to the rotation of the shelf.

9. The shelf unit according to claim 8 , wherein at least a portion of said bracket is arranged to tilt during the rotation of the shelf.

10. The shelf unit according to claim 5 , wherein said tracking device includes at least one roller element, and

wherein said rail runs along at least part of a circular path.

11. The shelf unit according to claim 5 , wherein said tracking device includes at least one roller element, and

wherein said height difference of the rail is proportional to the rotation of the shelf.

12. The shelf unit according to claim 5 , wherein said tracking device includes at least one roller element,

wherein said height difference of the rail is proportional to the rotation of the shelf, and

wherein said rail runs along at least part of a circular path.

13. The shelf unit according to claim 5 , wherein said tracking device tracks the rail of the shelf,

wherein two roller elements, adapted to be movably engaged with opposite sides of the rail, are arranged having a vertical separation into which the rail is fitted.

14. The shelf unit according to claim 13 , wherein said vertical separation of the two roller elements is fixed or guided by a spring such that each roller element presses onto its respective side of the rail, so as to control the position of the shelf.

15. The shelf unit according to claim 1 , said bracket further being arranged for mounting into an existing shelving system.

16. The shelf unit according to claim 1 , wherein said shelf is arranged to rotate about an asymmetrically positioned axis of rotation, which is positioned closer to the front edge of the shelf than to the rear side of the shelf.

17. The shelf unit according to claim 1 , further comprising a device for interconnecting one of said shelf units with at least one adjacently positioned one of shelf units.

18. A refrigerator comprising the shelf assembly according to claim 1 .

19. A cabinet comprising the shelf assembly according to claim 1 .
