Abstract (en)
[origin: EP0335839A2] The instant invention consists of a mechanical device, to be installed on motorised shutters, for the self-recording of the end of stroke slider, which stops the geared motor when the shutter reaches its top dead centre. The device in question essentially comprises two limit microswitches (16a, 16b) working together with their respective sliders (15a, 15b), screwed onto two threaded rods (2a, 2b), one on the right and one on the left, made to rotate by the same geared motor which sets the shutter in motion. Each threaded rod (2a, 2b) is made to rotate by its own drum (9a, 9b), coupling of which with the corresponding gear-motor (5a, 5b) can take place automatically by the simple reverse of the geared motor, due to a special and ingenious mechanism.
