  • Patent number: 8282175
    Abstract: An opening device including an elongate ejector ram mounted in a longitudinally displaceable manner in a housing and pretensioned at one end by a spring into a position in which it protrudes out of the housing and pushable back into the housing counter to the pretensioning. A releasable locking device locks the ejector ram in a position retracted in the housing. A tensioning device is provided forcibly displaces the ejector ram. When the movable furniture part is completely opened, a tensioning device forcibly displaces the ejector ram into the locking position retracted within the housing. The tensioning device converts the opening movement of the movable furniture part in the interior of the housing via a tensioning member having one end guided out of the housing into a movement pulling the ejector ram back into the retracted position.

  • Publication number: 20120126677
    Abstract: The invention is a device for a movable furniture part, such as a door, shutter or drawer, that includes a first attachment part fitted on a basic structure and connected, via an articulation mechanism, to a second attachment part fitted on the movable furniture part that pivots the movable furniture part, and a damping device for damping the relative movement during pivoting of the movable furniture part. The damping device includes a damper housing and an internal part accommodated on the damper housing that are movable in relation to one another, where the damper housing or the internal part serves as a contact part which contacts, at least temporarily, a portion of the device during pivoting of the furniture part. An adjusting arrangement adjusts the damping. The adjusting arrangement is mounted to a predefined fitting position that is changeable and the damping device is secured in the predefined fitting position.
