Title: Shutter obstacle detecting device
Inventor: MARUCHI KATSUMI
IPC: E06B9/84
Filed: 1989-04-07
Abstract: PURPOSE:To eliminate the limitation of an obstacle detecting area and to facilitate wiring execution by detecting reflected light from a detecting piece provided on the lower end portion of a shutter in such a manner as to tilt by a photoelectric switch to control a motor. CONSTITUTION:A detecting piece 12 which has a length corresponding to the substantially full length of the width of a shutter 3 and is capable of tilting when it contacts an obstacle is installed on the lower end portion of the shutter 3 in such a manner as to freely oscillate. The upper surface of the detecting piece 12 is formed as a reflecting surface, and a reflection type photoelectric switch 6 adapted to detect reflected light projected when the detecting piece 12 is not tilted and output a signal is disposed on the upper portion of a gate frame 1. When the detecting piece 12 hits an obstacle and tilts, and the photoelectric switch 6 does not receive light, according to the signal, a control means 5 provided on the gate frame 1 side stops the drive of a motor 4. Thus, electric wiring is provided only on the gate frame 1 side, and it is not required on the shutter 3 side.
