Abstract

An arrangement includes a drawer pull-out guide and a locking device for releasably locking a furniture part. The drawer pull-out guide includes a carcass rail to be fixed to a furniture carcass and an extension rail, the extension rail being displaceably supported between a fully closed position and a fully open position. The locking device includes a first locking component to be fixed to the furniture carcass, and a second locking component to be fixed to the extendably-supported furniture part. The first locking component and the second locking component can be releasably locked together, and the second locking component includes a base member and a locking element for releasably locking the first locking component. The locking element is pivotally supported on the base member, and the extension rail of the drawer pull-out guide can be releasably locked by the locking device in or immediately before the fully open position.

First claim

The invention claimed is:

1. An arrangement comprising:
a drawer pull-out guide; and
a locking device for releasably locking a furniture part extendably-supported on a furniture carcass in at least one position relative to the furniture carcass,
wherein the drawer pull-out guide includes a carcass rail configured to be fixed to the furniture carcass and an extension rail, the extension rail being displaceably supported relative to the carcass rail between a fully closed position and a fully open position,
wherein the locking device includes a first locking component configured to be fixed to the furniture carcass, and a second locking component configured to be fixed to the extendably-supported furniture part, the first locking component and the second locking component being configured to be releasably locked to one another,
wherein the second locking component includes a base member and a locking element for releasably locking the second locking component to the first locking component, the locking element being pivotally supported about a pivoting axis on the base member, and the extension rail of the drawer pull-out guide is releasably lockable by the locking device in the fully open position or in a position immediately before reaching the fully open position so as to prevent movement of the extension rail in a closing direction, and
wherein the first locking component includes a force storage member for releasably locking the locking element.

2. The arrangement according to claim 1 , wherein the second locking component includes a coupling portion for receiving a synchronization rod, and the coupling portion is connected to the locking element in a movement-coupled manner.

3. The arrangement according to claim 2 , wherein the coupling portion includes a non-circular cross-section for transmitting a pivoting movement in a form-locking manner.

4. The arrangement according to claim 3 , wherein the coupling portion is coaxially arranged to the pivoting axis of the locking element.

5. The arrangement according to claim 1 , wherein the second locking component includes an actuating lever for unlocking the first locking component and the second locking component, and the actuating lever is connected to the locking element in a movement-coupled manner.

6. The arrangement according to claim 1 , wherein the locking element is configured to engage into a locking recess of the first locking component in a locked condition between the first locking component and the second locking component.

7. The arrangement according to claim 1 , wherein the base member of the second locking component includes a fastening interface for fastening the second locking component to the extendable furniture part.

8. The arrangement according to claim 1 , wherein the second locking component includes a spring element for pre-stressing the locking element in a direction of a locking position.

9. The arrangement according to claim 1 , wherein the first locking component includes a fastening device for fastening the first locking component to the furniture carcass.

10. The arrangement according to claim 9 , wherein the fastening device is configured to be fixed to the carcass rail of the drawer pull-out guide.

11. The arrangement according to claim 1 , wherein the first locking component includes a lead-in chamfer for displaceably guiding the locking element.

12. The arrangement according to claim 1 , wherein the locking device is a first locking device, the arrangement further comprising a second locking device, wherein the first locking device is to be arranged on a first side of the extendable furniture part and the second locking device is to be arranged on a second side of the extendable furniture part opposing the first side.

13. The arrangement according to claim 12 , further comprising a synchronization device including a synchronization rod, the synchronization rod being configured to be connected to pivotable locking elements of the first locking device and the second locking device in a movement-coupled manner.

14. The arrangement according to claim 12 , wherein the locking element of the first locking device and a locking element of the second locking device are configured to be connected to one another in a movement-coupled manner via a synchronization device.

15. An arrangement comprising:
a drawer pull-out guide;
a first locking device for releasably locking a furniture part extendably-supported on a furniture carcass in at least one position relative to the furniture carcass;
a second locking device, wherein the first locking device is to be arranged on a first side of the extendably-supported furniture part and the second locking device is to be arranged on a second side of the extendably-supported furniture part opposing the first side; and
a synchronization device including a synchronization rod, the synchronization rod being configured to be connected to pivotable locking elements of the first locking device and the second locking device in a movement-coupled manner,
wherein the drawer pull-out guide includes a carcass rail configured to be fixed to the furniture carcass and an extension rail, the extension rail being displaceably supported relative to the carcass rail between a fully closed position and a fully open position,
wherein the first locking device includes a first locking component configured to be fixed to the furniture carcass, and a second locking component configured to be fixed to the extendably-supported furniture part, the first locking component and the second locking component being configured to be releasably locked to one another,
wherein the second locking component includes a base member and a first one of the pivotable locking elements for releasably locking the second locking component to the first locking component, the first one of the pivotable locking elements being pivotally supported about a pivoting axis on the base member, and the extension rail of the drawer pull-out guide is releasably lockable by the first locking device in the fully open position or in a position immediately before reaching the fully open position so as to prevent movement of the extension rail in a closing direction.

16. An arrangement comprising:
a drawer pull-out guide; and
a locking device for releasably locking a furniture part extendably-supported on a furniture carcass in at least one position relative to the furniture carcass,
wherein the drawer pull-out guide includes a carcass rail configured to be fixed to the furniture carcass and an extension rail, the extension rail being displaceably supported relative to the carcass rail between a fully closed position and a fully open position,
wherein the locking device includes a first locking component configured to be fixed to the furniture carcass, and a second locking component configured to be fixed to the extendably-supported furniture part, the first locking component and the second locking component being configured to be releasably locked to one another,
wherein the second locking component includes a base member and a locking element for releasably locking the second locking component to the first locking component, the locking element being pivotally supported about a pivoting axis on the base member, and the extension rail of the drawer pull-out guide is releasably lockable by the locking device in the fully open position or in a position immediately before reaching the fully open position so as to prevent movement of the extension rail in a closing direction,
wherein the second locking component includes a coupling portion for rec
