Abstract

An extendable table sliding system for an extendable table is provided. The sliding system includes at least two parts being moveable relative each other and together forming at least a part of the extendable table sliding system, wherein one of said at least two parts includes at least one sliding surface being coated with a lacquer including a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.

First claim

The invention claimed is:

1. An extendable table sliding system for an extendable table, comprising at least two parts being moveable relative each other and together forming at least a part of the extendable table sliding system, wherein one of said at least two parts comprises at least one sliding surface being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction, wherein the other one of said parts of the extendable table sliding system is provided with at least one sliding member, the interface between the sliding surface and the at least one sliding member forming a linear plain bearing to allow for a relative linear movement of the sliding member along the longitudinal axis of the sliding surface, wherein at least the part of said at least one sliding member being in contact with the sliding surface is made of a plastic.

2. The sliding system according to claim 1 , wherein the sliding surface is formed on at least one surface of a C-shaped groove in one of said at least two parts.

3. The sliding system according to claim 2 , wherein the C-shaped groove is integrally formed in one of said at least two parts.

4. The sliding system according to claim 1 , wherein the sliding surface is formed by an insert received in a recess in one of said at least two parts.

5. The sliding system according to claim 4 , wherein the sliding surface is formed by the insert, wherein said part being provided with the recess is made of a material being different from the material of said insert.

6. The sliding system according to claim 5 , wherein said material of the part being provided with the recess is a wooden material, or a plastic material.

7. The sliding system according to claim 1 , wherein the sliding surface is formed by a member protruding outwards from one of said at least two parts.

8. The sliding system according to claim 1 , wherein said sliding surface is formed by at least one of an upper sliding surface, a lower sliding surface, and a distal sliding surface, or any combination thereof.

9. The sliding system according to claim 1 wherein at least the part of said at least one sliding member being in contact with the sliding surface is made of a plastic comprising a polymer with polar groups.

10. The sliding system according to claim 1 , wherein at least the part of said at least one sliding member in contact with the sliding surface is made of a plastic comprising a polymer selected from the group of polymers consisting of polyoxymethylenes (POM), polyesters, polyamides (PA), polyvinyl chloride (PVC), polyphenylene sulfide (PPS), polyaryletherketone (PAEK), and Polytetrafluoroethylene (PTFE).

11. The sliding system according to claim 1 , wherein said at least one sliding member is in its entirety made from a plastic.

12. The sliding system according to claim 1 , wherein the part of said at least one sliding member arranged to slide along the sliding surface comprises at least one blade extending in the sliding direction.

13. The sliding system according to claim 12 , wherein said sliding member is provided with at least one blade extending in a first direction from a first surface of the sliding member, and at least one blade extending in a second direction from a second surface of the sliding member, wherein said first and second surfaces are parallel, and wherein said first direction is opposite to said second direction.

14. The sliding system according to claim 12 , wherein said sliding member is provided with at least one blade extending in a first direction from a first surface of the sliding member, and at least one blade extending in a third direction from a third surface of the sliding member, wherein said first and third surfaces are non-parallel, and wherein said first direction is perpendicular to said third direction.

15. The sliding system according to claim 1 , wherein the at least one sliding member comprises at least one individual contact point in contact with the sliding surface, the contact area of each individual contact point being less than 3 mm 2 .

16. The sliding system according to claim 1 , wherein the thickness of the lacquer coated on the sliding surface is 100 μm or less.

17. The sliding system claim 1 , wherein the sliding surface is formed by an aluminum member having a surface onto which the lacquer is applied, and wherein the surface of the aluminum member has been electrophoretically coated with a resin and subsequently heat cured to form the lacquer coated on the sliding surface, and wherein the lipophilic composition coating comprises compounds comprising C6 to C40 non-aromatic hydrocarbyl groups.

18. An extendable table, comprising at least one sliding system according to claim 1 wherein one of said two parts of the extendable table sliding system is fixed to the table, while the other of said at least two parts forms an extendable part of the extendable table sliding system of the table.

19. The extendable table according to claim 18 , wherein a table surface is fixedly attached to one of said at least two parts, and wherein optionally an extension table surface is releasably attachable to one of said at least two parts.

20. The extendable table according to claim 1 , wherein each one of said two parts comprises two parallel members, and wherein one parallel member of each one of the two parts forms a first sliding system, and the other parallel member of each one of the two parts forms a second sliding system, and wherein optionally the two parallel members of each one of said two parts are fixedly attached to each other by means of at least one transverse beam.
