摘要

Force-transferring and impact-absorbing connecting device connects a door leaf (12) and a drive device. Spiral springs (5) are positioned on both sides of a piston (8) arranged in a cylindrical housing (7). The springs hold the piston in its middle position in a pre-tensioned state. Preferred Features: The damping effect produced by the springs acts in both directions. The door leaf can be fixed using a flat sheet (3) having holes (2). The sheet is directly connected to the connecting rod (4) of the spring.
