Abstract

A guide device for guiding a furniture part movable relative to a furniture body comprises: a guide unit including a body rail fixable to the furniture body; a sliding rail connectable to the movable furniture part and displaceably mounted relative to the body rail via a rail guide movable in a sliding direction, wherein the rail guide is mounted displaceably relative to the body rail and the one sliding rail and, when withdrawn to an open position, abuts against stops on the body rail and sliding rail; and a damper to damp the impact of the rail guide on at least one of the stops. The rail guide comprises at least two guide sections arranged behind one another in the sliding direction. The guide sections are connected to one another by a damping section that is flexible in the sliding direction and equipped with the damper.

First claim

What is claimed is:

1. A guide device for guiding a furniture part moveable relative to a furniture body, comprising:
at least one guide unit including a body rail fixable to the furniture body;
at least one sliding rail connectable to the moveable furniture part and displaceably mounted relative to the body rail via a rail guide moveable in a sliding direction, wherein the rail guide is mounted displaceably relative to the body rail and relative to the at least one sliding rail, wherein, in a withdrawn, open position, the rail guide abuts against a stop on the body rail and against a stop on the sliding rail;
a locking mechanism; and
a damper to damp the impact of the rail guide on at least one of the stops, wherein:
the rail guide comprises: at least two guide sections arranged behind one another in the sliding direction; a connecting rod to connect the guide sections, the connecting rod comprising a first rod section fastened to one of the guide sections and a second rod section fastened to another of the guide sections; and a damping section arranged between the first and second rod sections, the damping section being flexible in the sliding direction and equipped with the damper;
the locking mechanism is arranged to be brought into engagement with the rail guide into a locking position in which relative movement between the guide sections is blocked;
the connecting rod is part of a rail support to support the sliding rail on the body rail, wherein the rail support comprises a combination of a rack and at least one pinion, with the connecting rod being the rack and with the at least one pinion meshingly engageable with the connecting rod when the furniture part is inserted or pulled out; and
the at least one pinion is part of the locking mechanism.

2. The guide device of claim 1 , wherein the locking mechanism engages the rail guide at the damper to block the flexibility of the damper.

3. The guide device of claim 1 , wherein the damper comprises at least one spring element mounted on the guide sections of the rail guide.

4. The guide device of claim 1 , wherein the at least one pinion in the locking position engages the teeth of the spring element.

5. The guide device of claim 1 , wherein the rail guide comprises at least one roller carriage with a carriage housing and castors rotationally mounted thereon.

6. The guide device of claim 1 , wherein the at least one sliding rail comprises a middle rail displaceably mounted relative to the body rail via a lower module of the rail guide, and an extension rail displaceably mounted relative to the middle rail via an upper module of the rail guide.

7. The guide device of claim 6 , wherein both the upper and lower modules of the rail guide are equipped with damping sections.

8. The guide device of claim 1 , wherein the furniture part is a drawer, door, or flap.

9. An item of furniture, comprising:
the guide device of claim 1 ;
a furniture body; and
a furniture part moveably guided relative to the furniture body via the guide device.

10. A guide device for guiding a furniture part moveable relative to a furniture body, comprising:
at least one guide unit including a body rail fixable to the furniture body;
at least one sliding rail connectable to the moveable furniture part and displaceably mounted relative to the body rail via a rail guide moveable in a sliding direction, wherein the rail guide is mounted displaceably relative to the body rail and relative to the at least one sliding rail, wherein, in a withdrawn, open position, the rail guide abuts against a stop on the body rail and against a stop on the sliding rail;
a locking mechanism; and
a damper to damp the impact of the rail guide on at least one of the stops, wherein:
the rail guide comprises: at least two guide sections arranged behind one another in the sliding direction; a connecting rod to connect the guide sections, the connecting rod comprising a first rod section fastened to one of the guide sections and a second rod section fastened to another of the guide sections; and a damping section arranged between the first and second rod sections, the damping section being flexible in the sliding direction and equipped with the damper;
the locking mechanism is arranged to be brought into engagement with the rail guide into a locking position in which relative movement between the guide sections is blocked;
the connecting rod is part of a rail support to support the sliding rail on the body rail, wherein the rail support comprises a combination of a rack and at least one pinion, with the connecting rod being the rack and with the at least one pinion meshingly engageable with the connecting rod when the furniture part is inserted or pulled out; and
the rack has a toothed region with a plurality of teeth arranged behind one another in the sliding direction, the toothed region extending over the first rod section, the damping section, and the second rod section.

11. The guide device of claim 10 , wherein the damper comprises a spring element having the teeth of the toothed region.

12. The guide device of claim 10 , wherein the at least one pinion is part of the locking mechanism.
