Abstract

A sliding screen system for a sliding screen comprising a linear slide bar and at least one sliding member. The linear slide bar has a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide bar with low friction. The sliding system is arranged to support a sliding screen, such as a sliding door or a sliding curtain, connected to the sliding member to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar.

Claims (24)

1. A sliding screen sliding system, comprising a linear slide bar having a slide layer with lowered friction, and at least one sliding member, wherein the linear slide bar and the sliding member are arranged in contact, whereby the interface between the slide layer of the slide bar and a part of the sliding member being in contact with the slide layer forms a linear plain bearing to allow for linear movement of the sliding member along the longitudinal axis of the linear slide bar, the sliding member being provided with a fastening arrangement adapted for connection to a sliding screen to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar, and wherein at least the part of said sliding member being in contact with the slide layer is made of a plastic, and wherein the part of said sliding member to slide over the slide layer is configured as a blade extending in the sliding direction, wherein the sliding member comprises at least one individual contact point in contact with the slide bar at the interface between the slide bar and the sliding member, the contact area of each individual contact point being less than 3 mm 2 .

2. The sliding system according to claim 1 , wherein said sliding system comprises at least two sliding members, wherein the interface between the slide layer of the slide bar and each of the sliding members forms a linear plain bearing to allow for linear movement of the sliding members along the longitudinal axis of the linear slide bar.

3. The sliding system according to claim 1 , wherein the slide layer is present in a groove extending along the longitudinal axis of the slide bar;

or wherein the slide layer is present on a hill extending along the longitudinal axis of the slide bar.

4. The sliding system according to claim 1 , wherein the contact pressure in said at least one contact point is at least 4 N/mm 2 .

5. The sliding system according to claim 1 , wherein the linear slide bar has two parallel slide layers, the first slide layer extending along a first longitudinal axis of the slide bar, and the second slide layer being parallelly displaced in relation to the first slide layer and extending along a second longitudinal axis of the slide bar, wherein the part of said sliding member to slide over the slide layers is configured as two parallel, displaced blades extending in the sliding direction and arranged along different longitudinal axes.

6. The sliding system according to claim 1 , wherein the slide bar is an aluminum or steel bar.

7. The sliding system according to claim 1 , wherein the slide layer is coated with a lipophilic composition coating.

8. The sliding system according to claim 7 , wherein the lipophilic composition coating coated on the slide layer comprises at least 25 wt. %, of compounds comprising C6 to C40 alkyl groups.

9. The sliding system according to claim 8 , wherein the lipophilic composition coating coated on the slide layer comprises at least 25 wt. % C6 to C40 non-aromatic hydrocarbons.

10. The sliding system according to claim 7 , wherein the lipophilic composition coating comprises triglycerides and/or fatty acids.

11. The sliding system according to claim 10 , wherein the lipophilic composition coating comprises 1 to 40 wt. %, or at least 25 wt. %, triglycerides and/or fatty acids.

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

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

14. A sliding screen arrangement comprising:

a sliding system comprising a linear slide bar having a slide layer with lowered friction, and at least one sliding member, wherein the linear slide bar and the sliding member are arranged in contact, whereby the interface between the slide layer of the slide bar and a part of the sliding member being in contact with the slide layer forms a linear plain bearing to allow for linear movement of the sliding member along the longitudinal axis of the linear slide bar, wherein at least the part of said sliding member being in contact with the slide layer is made of a plastic, and wherein the part of said sliding member to slide over the slide layer is configured as a blade extending in the sliding direction, wherein the sliding member comprises at least one individual contact point in contact with the slide bar at the interface between the slide bar and the sliding member, the contact area of each individual contact point being less than 3 mm 2 ; and

a sliding screen,

wherein the sliding member being provided with a fastening arrangement adapted for connection to the sliding screen to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar, and wherein said sliding member is arranged to support the sliding screen to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar, and wherein the sliding screen is arranged hanging from the linear slide bar, or wherein the sliding screen is a sliding door which is arranged standing on the linear slide bar.

15. The sliding screen arrangement according to claim 14 , wherein the sliding screen is arranged hanging from the linear slide bar, and wherein the sliding screen arrangement comprises a linear guide bar to be arranged at the lower end of the sliding screen, the linear guide bar being provided with a guiding channel extending along the longitudinal axis of the linear guide bar, wherein said guiding channel is to receive a guiding member arranged at the lower end of the sliding screen.

16. The sliding screen arrangement according to claim 14 , wherein the sliding screen is a sliding door which is arranged standing on the linear slide bar, and wherein the linear slide bar is provided with a hill extending along the longitudinal axis of the slide bar and defining a slide direction along the longitudinal axis of the slide bar.

17. The sliding screen arrangement according to claim 16 , wherein the sliding screen arrangement comprises a linear guide bar to be arranged at the upper end of the sliding door, the linear guide bar being provided with a guiding channel extending along the longitudinal axis of the linear guide bar, wherein said guiding channel is to receive a guiding member arranged at the upper end of the sliding door.

18. A sliding screen sliding system, comprising at least one sliding member having a slide surface with lowered friction, and a linear slide bar, wherein the linear slide bar and the sliding member are arranged in contact, whereby the interface between sliding member and the linear slide bar forms a linear plain bearing to allow for linear movement of the sliding member along the longitudinal axis of the linear slide bar, the sliding member being provided with a fastening arrangement adapted for connection to a sliding screen to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar, wherein the linear slide bar is a plastic profile, wherein the plastic profile is provided with a ridge extending along the longitudinal axis of the profile, wherein the linear slide bar comprises at least one individual contact point in contact with the sliding member at the interface between the slide bar and the sliding member, the contact area of each individual contact point being less than 3 mm 2 .

19. The sliding system according to claim 18 , wherein the slide surface is coated with a lipophilic composition coating.

20. The sliding system according to claim 18 , wherein the plastic profile is provided with a sliding channel for the slide member to slide in, at least on interior surface of the channel being provided with the ridge extending along the longitudinal axis of the plastic profile.
