Abstract

A sliding and pivoting mechanism of a rack of an item of furniture or domestic appliance for extending and raising the rack out of a body of the item of furniture or domestic appliance, having at least two pivoting arms which are fixed rotatably to at least one of the side walls of the body with a first end parallel to the plane of the side walls, and are arranged spaced apart parallel to each other, wherein a guide rail is fixed pivotably to respective second ends of the pivoting arms parallel to the plane of the side walls in such a manner that the guide rail can be pivoted out of a lower position within the body into a raised, upper position at least partially outside the body, and at least one running rail which is displaceable linearly in the guide rail and to which the rack is fastened, wherein the sliding and pivoting mechanism has a locking mechanism which is arranged on the guide rail and on one of the pivoting arms and is actuable by an activator fixed on the running rail in order to prevent a simultaneous pivoting and sliding movement of the running rail.

First claim

The invention claimed is:

1. A sliding and pivoting mechanism of a rack of an item of furniture or of a domestic appliance for pulling out and raising the rack from a body of the item of furniture or of the domestic appliance, said body having an inside and an outside and at least one side wall, said sliding and pivoting mechanism comprising
at least two pivot arms which are rotatably securable to at least one of the at least one side wall of the body directly or through an intervening side wall holder with a first end parallel to a plane of the at least one side wall and which are arranged spaced part from one another in parallel,
wherein a guide rail is secured on the respective second ends of the pivot arms so as to be pivotable in such a manner parallel to the plane of the side walls that the guide rail is pivotable from a bottom position inside the body into a raised, top position at least partially outside of the body,
at least one running rail which is linearly displaceable in the guide rail and to which the rack is fastenable, wherein
the sliding and pivoting mechanism comprises a locking mechanism, which is arranged on the guide rail and on one of the pivot arms and can be actuated by an activator which is fixed on the running rail, for preventing the running rail from simultaneously sliding and pivoting.

2. The sliding and pivoting mechanism as claimed in claim 1 , wherein the locking mechanism comprises a web, which is held so as to be pivotable and resilient on one of the pivot arms, with a bolt which protrudes toward the guide rail and is guidable along a guide path, which is fastened on the guide rail, from a first locking position into at least one further locking position.

3. The sliding and pivoting mechanism as claimed in claim 2 , wherein the guide path is embodied as a curve portion which is defined by a first locking groove and at least one further locking groove.

4. The sliding and pivoting mechanism as claimed in claim 2 , wherein the guide path and the locking grooves are embodied on a plate which is connected fixedly to the guide rail.

5. The sliding and pivoting mechanism as claimed in claim 2 , wherein a spring element, which holds the web and a second of the two pivot arms together proximate the bolt, is arranged between the web and the second pivot arm.

6. The sliding and pivoting mechanism as claimed in claim 5 , wherein the spring element can be latched in an audibly perceivable manner in or on a projection which is provided on the pivot arm when the spring reaches a locking position in which the running rail may not simultaneously pivot and slide.

7. The sliding and pivoting mechanism as claimed in claim 1 , wherein the activator, which is fixed on the running rail, comprises a first stop configured to allow the locking bolt to move in a direction of extension (A) of the running rail with respect to the guide rail to a position blocking a pivoting movement of the pivot arms in the first locking groove when the running rail is pulled out.

8. The sliding and pivoting mechanism as claimed in claim 1 , wherein the activator, which is fixed on the running rail, comprises a guide which guides the locking bolt along the guide path when the pivot arms are pivoted.

9. The sliding and pivoting mechanism as claimed in claim 1 , wherein the activator, which is fixed to the running rail, comprises a web in the form of a ramp operable to move the locking bolt in a direction of extension (A) out of a position wherein the locking bolt blocks a pivoting movement of the pivot arms in the second locking groove when the running rail is pulled out.

10. The sliding and pivoting mechanism as claimed in claim 1 , wherein the activator comprises at least one fastening element for fixing the rack to the activator.

11. The sliding and pivoting mechanism as claimed in claim 1 , wherein the locking bolt is guided in a guide groove of a second guide arm which is aligned perpendicular to the longitudinal extension of the second guide arm.

12. The sliding and pivoting mechanism as claimed in claim 1 , wherein at least one raising, lowering or raising and lowering aid, which is secured on one of the at least one side wall of the body directly or through an intervening side wall holder and on one of the pivot arms, is provided for supporting a pivoting movement of the pivot arms.

13. The sliding and pivoting mechanism as claimed in claim 1 , wherein a side wall holder, on which the arms and a raising, lowering or raising and lowering aid of a height-adjustment mechanism are secured, is fastened on at least one of oppositely located ones of the at least one side wall of the body.

14. The sliding and pivoting mechanism as claimed in claim 13 , wherein the raising and lowering aid is embodied as an energy storage means.

15. The sliding and pivoting mechanism of claim 14 , wherein the energy storage means is a tension spring.

16. The sliding and pivoting mechanism of claim 14 , wherein the energy storage means is a pneumatic spring.

17. The sliding and pivoting mechanism as claimed in claim 1 , wherein a cover, which covers a side face of the sliding and pivoting mechanism at least in part, is arranged on a side of the sliding and pivoting mechanism remote from the rack.

18. The sliding and pivoting mechanism as claimed in claim 17 , wherein a web with a visually recognizable control strip is provided on the cover, the web operable to indicate whether the sliding and pivoting mechanism is in a locking position in which the running rail may not simultaneously pivot and slide or a non-locking position in which the running rail may simultaneously pivot and slide.

19. An item of furniture having a furniture body and at least one rack which is fixed in the furniture body with a pivoting and sliding mechanism, by way of which the rack can be pulled and raised out of the furniture body, wherein the pivoting and sliding mechanism is embodied according to claim 1 .

20. A domestic appliance comprising the sliding and pivoting mechanism according to claim 1 and a rack attached to the sliding and pivoting mechanism, the sliding and pivoting mechanism operable to enable the rack to be pulled out and raised from an interior of the domestic appliance.
