Abstract

An actuating drive for moving a furniture part movably supported relative to a furniture carcass, the actuating drive including at least one pivotally mounted actuating arm for moving the movable furniture part, a spring device for applying a force to the actuating arm, and a locking device for releasably locking the actuating arm. The locking device includes at least one movably-mounted locking element cooperating with at least one locking recess in a position in which the actuating arm is locked, and the locking element can be unlocked from the at least one locking recess by a switch element to be operated manually and also by a control portion arranged on the actuating arm. The control portion can be acted upon by mounting the movable furniture part to the actuating arm.

First claim

1 . An actuating drive for moving a furniture part movably supported relative to a furniture carcass, comprising:
at least one pivotally mounted actuating arm for moving the movable furniture part, a spring device for applying a force to the actuating arm, a locking device for releasably locking the actuating arm, wherein the locking device includes at least one movably-mounted locking element cooperating with at least one locking recess in a position in which the actuating arm is locked, wherein the locking element can be unlocked from the at least one locking recess by a switch element to be operated manually and also by a control portion arranged on the actuating arm, wherein the control portion can be acted upon by mounting the movable furniture part to the actuating arm.

2 . The actuating drive according to claim 1 , wherein the actuating arm, in a closed position, can be locked by a cooperation of the locking element with the at least one locking recess.

3 . The actuating drive according to claim 1 , wherein at least one second locking recess is provided, wherein the actuating arm, in an open position, can be locked by a cooperation of the locking element with the second locking recess.

4 . The actuating drive according to claim 3 , wherein at least a third locking recess is provided, wherein the actuating arm, in an intermediate position lying between the open position and the closed position and which preferably corresponds to the half-open position of the actuating arm, can be locked by a cooperation of the locking element with the third locking recess.

5 . The actuating drive according to claim 1 , wherein the switch element can be moved between a first switching position and a second switching position, wherein in the first switching position, the locking element is locked to the at least one locking recess, and in the second switching position, the locking element can be unlocked from the at least one locking recess.

6 . The actuating drive according to claim 1 , wherein the switch element is movably-mounted on the actuating arm.

7 . The actuating drive according to claim 1 , wherein the switch element has at least one first guide track, wherein the locking element can be moved in or along the at least one guide track by a manual actuation of the switch element or by acting upon the control portion.

8 . The actuating drive according to claim 7 , wherein the switch element has a second guide track, wherein a hinge axis member of the actuating arm can be moved in or along the second guide track by a manual actuation of the switch element or by acting upon the control portion.

9 . The actuating drive according to claim 1 , wherein the control portion is configured as a lever having two lever ends, the lever being pivotally mounted about a pivoting axis, a first lever end of the lever can be acted upon by a fitting portion to be fixed to the movable furniture part when the movable furniture part is mounted to the actuating arm, and a second lever end of the lever has a guide in or along which the locking element is displaceably arranged.

10 . The actuating drive according to claim 9 , wherein the actuating arm can be releasably latched to the fitting portion to be fixed to the movable furniture part.

11 . The actuating drive according to claim 1 , wherein the actuating arm is pivotally connected to a lever by a hinge axis member, wherein the locking device is operative between the actuating arm and the lever.

12 . The actuating drive according to claim 11 , wherein the at least one locking recess is formed or arranged on the lever.

13 . The actuating drive according to claim 1 , wherein the locking element is configured as a cylindrical pin.

14 . The actuating drive according to claim 1 , wherein the switch element and/or the control portion is or are pre-stressed by a spring element in a direction towards the locking position.
