Abstract
A retraction device for movable furniture parts has a driver movable along a first guide path, which is movable between a retracted position and a parked position and is directly or indirectly pretensioned into the retracted position by an energy storage device. The driver can be coupled to an activator in order to move the movable furniture part into a closed position. A method uses the driver for opening and closing the movable furniture part and tensioning and releasing a retraction device.
Claims15
A retraction device for movable furniture parts (3), comprising a driver (11) which is configured to be moved along a first guide path (10) between a retraction position and a parked position and is directly or indirectly pretensioned into the retraction position by an energy storage device, wherein the driver (11) is configured to be coupled to an activator (25) in order to move the movable furniture part (3) into a closed position, and further comprising an opening driver (23) which is movable along a second guide path (21) and is coupled to the driver (11) via a transmission gear (30), wherein the opening driver (23) is configured to be coupled to an opening activator (26) which moves the opening driver (23) along the second guide path (21) in an opening direction during an opening movement, wherein a distance traveled by the opening driver (23) is longer than a distance traveled by the driver (11).
A method for opening and closing a movable furniture part (3) and for clamping a retraction device, comprising the following steps:
- moving the movable furniture part (3) from a closed position in an opening direction, wherein an opening driver (23) moves a driver (11) in the opening direction via a transmission gear (30), the driver (11) being pretensioned in a closing direction by an energy storage device, wherein the opening driver (23) is moved faster than the driver (11);
- parking the driver (11) and the opening driver (23) in a parked position and decoupling of the movable furniture part (3) from the retraction device, and
- moving the movable furniture part (3) in the closing direction, wherein an activator (25) is coupled to the driver (11), which via the energy storage device moves the movable furniture part (3) and the opening activator (26) in the closing direction.
