Drive device for moving a movable furniture part

摘要

The invention relates to a drive device for moving a movable furniture part, in particular a drawer, said drive device acting as a latching and unlatching spring-loaded ejection device for ejecting the furniture part from a closed position in the opening direction and as a spring-loaded refraction device for retracting the furniture part into the closed position. The same spring spring-loads the drive device both when the latter acts as an ejection device and when the drive device acts as a refraction device.

主权项

1. A drive device for moving a movable furniture part, wherein the drive device comprises a spring arranged such that the drive device acts
as a lockable and unlockable spring-loaded ejection device for ejecting the furniture part from a closed position in an opening direction into a first open position, wherein the ejecting of the furniture part starts with the furniture part being in the closed position, and as a spring-loaded retraction device for retracting the furniture part from a second open position in a closing direction into the closed position, wherein the spring spring-loads the drive device both in its function as an ejection device and also in its function as a retraction device, wherein the spring has a relief travel, wherein between the second open position and the closed position the spring passes a first part of the relief travel in which the spring retracts the movable furniture part, the first part of the relief travel corresponding with a retraction spacing of the travel of the movable furniture part from the second open position in the closing direction into the closed position, wherein starting from the closed position and between the closed position and the first open position the spring passes a second part of the relief travel in which the spring ejects the movable furniture part, the second part of the relief travel corresponding with an ejection spacing of the travel of the movable furniture part from the closed position in the opening direction into the first open position, wherein the retraction spacing of the travel of the movable furniture part in the closing direction and the ejection spacing of the travel of the movable furniture part in the opening direction at least partly overlap, and wherein in a state in which the drive device is locked with the movable furniture part being in the closed position, unlocking of the drive device is triggered by applying pressure to the movable furniture part in the closing direction.
