Combined deceleration and acceleration device

摘要

In a combined deceleration and acceleration device for the controlled closing and opening of, for example, furniture parts, a base part consisting of a cylinder and a guide structure is provided wherein a drag element is movably supported by the guide structure, and a piston with a piston rod is connected to the drag element which has a park position remote from the cylinder and is biased by an energy storage structure toward the cylinder for moving the piston into the cylinder in a controlled decelerating manner while carrying along the drag element and a movable part engaged with the drag element.

主权项

1. A combined deceleration- and acceleration device (10) pre-installed in a housing (11) and comprising: a base part (21), a drag element (101) supported on the base part (21) so as to be movable thereon between an end position (7) and an opposite park position in which the drag element (101) is held in a form- or force-locking manner, a deceleration structure (41) comprising a cylinder piston unit (42) having a cylinder (51) and a piston (82) with a piston rod (87) being disposed in a vertical longitudinal center plane at one side of the base part (21), with the piston rod (87) being connected to the drag element (101) and an acceleration structure (91) including an energy storage element (92) arranged at the side of the base part (21) opposite the piston (82) and the piston rod (87) and having one end connected to the drag element (101), and the opposite end to the base part (21), the base part (21) being formed integrally with the cylinder (51) receiving the piston (82) of the cylinder, piston unit (42) and forming at least part of a guide structure (31) for the drag element (101), the combined deceleration and acceleration device, before installation thereof in the housing (11), being symmetrical with regard to said vertical longitudinal center plane.
