摘要

The device (10) has a support mechanism (30) arranged in a housing (20). An input shaft (40) is movably mounted at the support mechanism for receiving a door movement. A guide sleeve (50) is movably mounted in the support mechanism along a movement axis (B) and provided with a link guide unit (52). A spring device (60) i.e. spiral spring, acts on the guide sleeve through spring force along the axis. The input shaft comprises a guide pin (42) that is connected to the link guide unit. The guide unit is formed to reduce spring force in an open position and a closed position (S) of the shaft.
