Electrical device for remotely opening and closing so-called 'French style' shutters

摘要

Electrical device for remotely opening and closing either solid or louvred (slatted) so-called "French style" shutters. The invention relates to a low-voltage electrical mechanism which can be used to open and close outside shutters, to lock/unlock an espagnolette bolt having a round rod and to immobilise the shutter in the desired position. A motor (39) with reduction gear and drive disengageable by a knurled knob (28), these being housed in a reversible housing mounted on a hinged mechanism plate (43), transmits a rotational movement to an adjustable angled arm (51), the other end of which includes a screw (56) which travels in a guide (58) with an angled piece (elbow) (59) fastened to the shutter (71) which it accompanies. At the end of the movement, the fitted end of the arm (66) causes the espagnolette bolt (68) to rotate, while pushing a flat iron with adjustable bearing element (60) acting as the latch bolt. A helical spring (not shown) brings the espagnolette bolt back into the initial position when opening is caused. According to the invention, the device is particularly intended for opening and closing so-called "French style" shutters by means of electrical control. IMAGE
