Door i.e. glass door, closer for use in floor of building, has guiding slide with narrowing course deviating from circular form from closing position of door wing to opening position of door wing

摘要

The closer (10) has a guiding slide (50) arranged at a cylindrically formed mount housing (11). A radially spring loaded, moveable slid element (41) is moveable along the guiding slide, connected with a rotational axis (26) in a torque proof manner, and arranged perpendicular to the axis, which runs in the mount housing. The guiding slide has a narrowing course deviating from a circular form from a closing position of a door wing to an opening position of the door wing, where the closing position corresponds to a center position.
