Abstract

A pull-out guide for a drawer includes a carcass rail configured to be arranged on a side of a furniture carcass, and a drawer rail configured to be arranged on a drawer. The drawer rail is displaceably supported on the carcass rail in an opening- and closing direction, and the drawer rail has an upper side facing towards the drawer and a lower side spaced from the upper side by at least one side limb. A bearing device is provided for a synchronization rod of a synchronization device. The bearing device includes a fastening region for the synchronization rod, and the fastening region is arranged below the underside of the drawer rail.

First claim

The invention claimed is:

1. A pull-out guide for a drawer, comprising:
a carcass rail configured to be arranged on a side of a furniture carcass, the carcass rail having a vertical side limb to mount the carcass rail to the side of the furniture carcass,
a drawer rail configured to be arranged on a drawer, the drawer rail being displaceably supported on the carcass rail in an opening- and closing direction, the drawer rail having an upper side facing towards the drawer and a lower side spaced from the upper side by a side limb, and
a bearing device for supporting a synchronization rod of a synchronization device, the bearing device including a fastening region for receiving the synchronization rod,
wherein the fastening region is arranged below the underside of the drawer rail and between the drawer rail and the vertical side limb of the carcass rail in a horizontal direction.

2. The pull-out guide according to claim 1 , wherein the fastening region is a region in which the synchronization rod is to contact the bearing device.

3. The pull-out guide according to claim 1 , wherein the bearing device includes a carrier arranged on the carcass rail or on the drawer rail, and a receiving portion for receiving the synchronization rod, the receiving portion being movably arranged on the carrier.

4. The pull-out guide according to claim 3 , wherein the fastening region is configured as a recess in the receiving portion.

5. The pull-out guide according to claim 3 , wherein the receiving portion is pivotally arranged on the carrier.

6. An arrangement comprising at least two pull-out guides each being configured according to claim 1 , the at least two pull-out guides being further configured to be mounted to opposing sides of a furniture carcass.

7. The arrangement according to claim 6 , further comprising a synchronization device for synchronizing movements of the drawer rails of the at least two pull-out guides or for synchronizing movements of drive devices, the synchronization device including a synchronization rod.

8. The arrangement according to claim 7 , wherein the synchronization rod has two ends, and is supported via the two ends in the fastening regions of the bearing devices of the at least two pull-out guides, the synchronization rod extending below the drawer rails.

9. The arrangement according to claim 8 , wherein the synchronization rod, in an installed condition, is aligned horizontally and extends vertically below the drawer rails.

10. The arrangement according to claim 7 , further comprising a drive device for driving the drawer.

11. The arrangement according to claim 10 , wherein the drive device is configured as an ejection device for ejecting the drawer, the ejection device being configured to be unlocked by applying pressure to the drawer located in the closed position, and the ejection device being configured to move the drawer from the closed position in the opening direction and into an open position when the ejection device is unlocked.

12. The arrangement according to claim 11 , wherein the ejection device has a housing, an ejection slider movably supported in the housing, an ejection energy storage member fixed to the housing and to the ejection slider, a heart-shaped guide track formed in the housing, a locking pin configured to be locked in a locking recess of the guide track, and a control lever movably supported on the ejection slider, the control lever having the locking pin.

13. The arrangement according to claim 12 , wherein the housing forms the carrier of the bearing device.

14. The arrangement according to claim 12 , wherein a first coupling element is formed or arranged on the receiving portion, the first coupling element being configured to be coupled to a second coupling element in a movement-transmitting manner, wherein the second coupling element is formed or arranged on a synchronization slider movably supported on the housing.

15. The arrangement according to claim 14 , wherein the first coupling element is gear-shaped, the second coupling element is tooth racked-shaped, and the synchronization slider is supported on the housing so as to move linearly.

16. The arrangement according to claim 10 , wherein the drive device is mounted to a carcass rail of a first one of the at least two pull-out guides.

17. The arrangement according to claim 7 , wherein the synchronization rod is aligned perpendicular to the opening- and closing direction.

18. An item of furniture comprising:
a furniture carcass;
a drawer; and
the arrangement according to claim 6 .

19. The item of furniture according to claim 18 , wherein the fastening region of each of the two pull-out guides in an installation position is arranged horizontally below the underside of the respective drawer rail of each of the at least two pull-out guides.

20. An arrangement comprising:
at least two pull-out guides each including:
a carcass rail configured to be arranged on a side of a furniture carcass, the carcass rail having a vertical side limb to mount the carcass rail to the side of the furniture carcass,
a drawer rail configured to be arranged on a drawer, the drawer rail being displaceably supported on the carcass rail in an opening- and closing direction, the drawer rail having an upper side facing towards the drawer and a lower side spaced from the upper side by a side limb, and
a bearing device for supporting a synchronization rod of a synchronization device, the bearing device including a fastening region for receiving the synchronization rod, the fastening region being arranged below the underside of the drawer rail, and

a drive device configured to drive the drawer, the drive device being arranged between the drawer rail and the vertical side limb of the carcass rail of at least one of the at least two pull-out guides in a horizontal direction,
wherein the at least two pull-out guides are configured to be mounted to opposing sides of the furniture carcass.

21. The arrangement according to claim 20 , further comprising a synchronization device for synchronizing movements of the drawer rails of the at least two pull-out guides, the synchronization device including a synchronization rod.

22. An arrangement comprising:
at least two pull-out guides each including:
a carcass rail configured to be arranged on a side of a furniture carcass, the carcass rail having a vertical side limb to mount the carcass rail to the side of the furniture carcass,
a drawer rail configured to be arranged on a drawer, the drawer rail being displaceably supported on the carcass rail in an opening- and closing direction, the drawer rail having an upper side facing towards the drawer to support the drawer on the upper side thereof, and a lower side spaced from the upper side by a side limb, and
a bearing device for supporting a synchronization rod of a synchronization device, the bearing device including a fastening region for receiving the synchronization rod, the fastening region being arranged below the underside of the drawer rail and between the drawer rail and the vertical side limb of the carcass rail in a horizontal direction, and

a synchronization rod received by the fastening region of the bearing device of each of the at least two pull-out guides such that the drawer moves above and over the synchronization rod when moved in the opening or closing direction.
