Abstract

A guide system includes a first guide rail for guiding a door wing, a second guide rail for guiding the door wing. A carrier can move the door wing relative to the second guide rail in a direction extending transversely to the longitudinal direction of the first guide rail. A drive device has a force storage member, and the carrier can be at least partially ejected by the drive device from the retracted position of the carrier by a force of the force storage member. The drive device includes a coupling portion and a control curve, and the coupling portion and the control curve are decoupled over a large part of the movement of the carrier between the extended position and the retracted position. The carrier can be retracted into the retracted position starting from a position immediately before the retracted position when the coupling portion couples with the control curve.

First claim

The invention claimed is:

1. A guide system for guiding a movably-supported door wing, the guide system comprising:
a first guide rail having a longitudinal direction for guiding the door wing,
a second guide rail for guiding the door wing, the second guide rail extending transversely relative to the longitudinal direction of the first guide rail in a mounted condition,
a carrier by which the door wing, in the mounted condition, is to be moved relative to the second guide rail in a direction extending transversely to the longitudinal direction of the first guide rail between an extended position and a retracted position,
a drive device having a force storage member, wherein the carrier is configured to be ejected by the drive device from the retracted position at least over a region in a direction of the extended position by a force of the force storage member, wherein the drive device includes a coupling portion and a control curve,
wherein the coupling portion and the control curve are configured to be, over a large part of the movement of the carrier between the extended position and the retracted position, decoupled from one another, and the carrier, when the coupling portion couples with the control curve, is to be retracted into the retracted position starting from a position lying immediately before the retracted position.

2. The guide system according to claim 1 , wherein either:
the coupling portion is arranged on the carrier or is configured to be entrained with the carrier, and the control curve is arranged on the second guide rail or on a component fixed to a furniture carcass, or
the coupling portion is arranged on the second guide rail or on a component fixed to the furniture carcass, and the control curve is arranged on the carrier or is configured to be entrained with the carrier.

3. The guide system according to claim 1 , wherein the coupling portion is configured as a two-armed lever.

4. The guide system according to claim 3 , wherein the coupling portion has a first lever end and a second lever end, and the first lever end is configured to cooperate with the force storage member and the second lever end is configured to run along the control curve via a pressure portion.

5. The guide system according to claim 4 , wherein the pressure portion is a pressure roller.

6. The guide system according to claim 1 , further comprising a locking lever by which the coupling portion is to be releasably locked in the retracted position.

7. The guide system according to claim 6 , wherein the locking lever and the coupling portion are configured such that locking therebetween is to be released by overpressing the carrier from the retracted position into an overpressing position lying behind the retracted position.

8. The guide system according to claim 6 , wherein the locking lever is pre-stressed by a spring element in a direction of a release position in which the coupling portion is released.

9. The guide system according to claim 8 , wherein the spring element is configured to operate against a force of a timing element, so that the coupling portion is movable into the release position only after a predetermined time period by a delaying force of the timing element.

10. The guide system according to claim 9 , wherein the timing element includes a rotational damper having a pinion cooperating with a tooth arrangement arranged on the locking lever.

11. The guide system according to claim 10 , wherein the rotational damper is configured as a fluid damper.

12. The guide system according to claim 1 , wherein the force storage member includes a helical spring.

13. The guide system according to claim 12 , wherein the helical spring is a tension spring.

14. An arrangement comprising the guide system according to claim 1 , the arrangement further comprising:
the door wing.

15. The arrangement according to claim 14 , wherein the door wing is a first door wing, the arrangement further comprising a second door wing hingedly connected to the first door wing by a vertically extending axis in the mounted condition.

16. An item of furniture comprising the arrangement according to claim 14 .

17. The item of furniture according to claim 16 , wherein the door wing is a first door wing, the item of furniture further comprising a furniture carcass and a second door wing, the first door wing and the second door wing being movably supported relative to the furniture carcass, and the first door wing and the second door wing being hingedly connected to one another by a vertically extending pivoting axis in the mounted position,
wherein the first door wing and the second door wing are movable by the guide system between a first position, in which the first door wing and the second door wing are aligned substantially parallel to one another, and a second position, in which the first door wing and the second door wing are aligned substantially coplanar to one another.
