Abstract

898,856. Door checks. SCHONBERGER, W. June 23, 1960 [July 2, 1959], No. 22036/60. Class 65(1). A spring door closer has a check device comprising a magnet which is moved by the door into and then away from a magnetic field centred approximately at the middle of the movement of the magnet as the door is opened. The device may be of the cylinder and piston type (Fig. 1) or rotational type (Fig. 3) in which the door is connected to the permanent magnet 2 by rod 4 and is urged into the closed position by compression or torsion spring 3. On opening or closing, the magnet 5 assists the motion for the first half of the movement and retards it for the second half as the magnet 2 moves into and out of its magnetic field which may be regulated by a magnetic shunt 9 or if the magnet 5 is an electromagnet by varying the electric current. A magnet 7 placed at the end of the path of the magnet 2 co-operates with it to act as a catch in the open position.
