Abstract

The invention relates to a product supporting roller assembly comprising an elongate spine member and a plurality of rollers, each mounted on the spine member such that the rollers extend outwards on both sides of the spine member. The invention further relates to a product holding unit comprising a plurality of such product supporting roller assemblies. The invention further relates to a method of assembling an axle bearing, which may be used to assembly a product supporting roller assembly, the method comprising positioning a plurality of roller bearings and a roller bearing housing inside a hole, the roller bearings each being connected to a roller bearing holding means and the roller bearings being housed in the roller bearing housing, positioning an axle through the roller bearing housing, and disconnecting the roller bearings from the roller bearing holding means.

Claims

1. A product supporting roller assembly comprising:

an elongate spine member; and

a plurality of rollers, each mounted on the spine member such that the rollers extend outwards on both sides of the spine member.

2. A product supporting roller assembly as claimed in claim 1, wherein the spine member comprises a plurality of holes, each configured to receive one or more rollers.

3. A product supporting roller assembly as claimed in claim 1 or 2, wherein each roller is mounted on the spine member by means of a bearing assembly comprising a plurality of roller bearings.

4. A product supporting roller assembly as claimed in claim 3, wherein the bearing assembly comprises a roller bearing housing configured to hold the plurality of roller bearings around an inner surface of each hole.

5. A product supporting roller assembly as claimed in claim 4, wherein each roller is configured to be mounted in rotating contact with the roller bearings.

6. A product supporting roller assembly as claimed in any one of claims 2-5, wherein each roller comprises an axle mounted through one of the holes in the spine member and two product supporting rollers mounted on each end of the axle.

7. A product supporting roller assembly as claimed in claim 6, wherein the roller bearings extend into recesses in the product support rollers such that rotation of the product supporting rollers causes the roller bearings to rotate around the inner surface of the holes.

8. A product supporting roller assembly as claimed in any one of the preceding claims, wherein each roller lies in substantially the same plane as an adjacent roller.

9. A product supporting roller assembly as claimed in claim 8, wherein all the rollers lie in the same plane to form a substantially flat rolling surface.

10. A product supporting roller assembly as claimed in any one of the preceding claims, wherein each roller is substantially parallel to an adjacent roller.

11. A product supporting roller assembly as claimed in claim 10, wherein all the rollers are

12. A product supporting roller assembly as claimed in any one of the preceding claims, wherein the rollers extend outwards from the spine member at right angles.

13. A product supporting roller assembly as claimed in any one of the preceding claims, wherein the rollers extend substantially the same distance outwards on either side of the spine member.

14. A product supporting roller assembly as claimed in any one of the preceding claims, wherein the spine member is configured to be mounted on a support portion, the support portion being adapted to be mounted on a shelf.

15. A product supporting roller assembly as claimed in any one of the preceding claims, wherein the spine member and/or the support portion is/are configured to connect to a front portion and/or a back portion.

16. A product supporting roller assembly as claimed in claim 15, wherein the front portion comprises, or is connectable to, a barrier means, the barrier means acting to prevent product supported on the roller assembly from rolling off the front of the roller assembly.

17. A product supporting roller assembly as claimed in claim 15 or 16, wherein the front portion, back portion and/or a shelf engagement portion of the product supporting roller assembly comprise one or more track engagement means for engaging to a track.

18. A product supporting roller assembly as claimed in any one of the preceding claims, wherein the spine member is formed from an extruded length of a material.

19. A product supporting roller assembly as claimed in any one of the preceding claims, wherein the spine member comprises first and second rows of holes, the first and second rows of holes having different spacings between holes.

20. A product holding unit comprising one or more product supporting roller assemblies according to any one of claims 1-19.

21. A product holding unit as claimed in claim 20, wherein the product supporting roller assemblies have a longitudinal axis inclined downwards from the rear of the unit to the front of the unit such that product supported on the roller assemblies travels under gravity towards the front of the unit.

22. A product holding unit as claimed in claim 20 or 21, wherein the unit comprises more than one roller assembly arranged adjacently to define a shelf surface.

23. A product holding unit as claimed in claim 22, wherein the product holding unit comprises one or more roller assembly receiving means arranged substantially horizontally in a substantially co-planar arrangement with the shelf surface, the roller assemblies being configured to be moveable along the roller assembly receiving means.

24. A product holding unit as claimed in claim 23, wherein the roller assembly receiving means comprises a track, the track comprising an engagement portion to couple with an engagement portion of the track engagement means.

25. A product holding unit as claimed in claim 23 or 24, wherein the holding unit comprises means for fixing the roller assemblies in position on the roller assembly receiving means.

26. A product holding unit as claimed in any one of claims 20-25, wherein the holding unit further comprises one or more barrier means for preventing product rolling off the front end of one or more of the roller assemblies.

27. A product holding unit as claimed in any one of claims 20-26, wherein the holding unit further comprises one or more dividers adapted to be mounted between two roller assemblies.

28. A product holding unit as claimed in claim 27, wherein one or more of the dividers comprise barrier means for preventing product rolling off the front end of one or more of the roller assemblies.

29. A product holding unit as claimed in claim 28, wherein two adjacent dividers combine to form a barrier means for preventing product supported between said adjacent dividers from rolling off the front end of one or more of the roller assemblies.

30. A method of assembling an axle bearing, the method comprising:

positioning a plurality of roller bearings and a roller bearing housing inside a hole, the roller bearings each being connected to a roller bearing holding means and the roller bearings being housed in the roller bearing housing;

positioning an axle through the roller bearing housing; and

disconnecting the roller bearings from the roller bearing holding means.

31. A method as claimed in claim 30, wherein the roller bearing housing comprises the roller bearing holding means such that the roller bearings are connected to the roller bearing housing.
