Title: Automatic window closing mechanism - has coil spring driven pinion meshing with rack fastened to window leaf
Inventor: STEZELBERG ROLF DR
IPC: E05F1/10
Filed: 1973-11-21
Abstract: The arrangement is a further development of the device as in 1303272, which produces the translation of the rotary movement of the spring driven shaft fixed to the window frame to the window leaf by means of a pulley-and-string arrangement. The present variant uses a segment shaped or straight rack fitted to the pinion in such a way that when the window is opened the coil spring is being tensioned. The spring when it unwinds turns the pinion to swing the window to the closed position. The use of a straight rack is preferable as a stronger assembly may then be produced.
