Title: Device for opening, closing and locking shutters with manual control on the inside without opening the windows
Inventor: FRANCOIS HUG
IPC: E05F11/36
Filed: 1991-07-19
Abstract: The invention makes it possible to open, close and lock shutters without opening the windows; the device is composed of an emitter member, of which the element for connection to the receiving member is a steel cable, sliding in a metal sheath, thus forming a flexible mechanical control. A manual action on a handle (1), and therefore a return (transmission member), placed in articulation on an inside support fixed to the wall, gives rise to pulling on one of the two lengths of the steel cable (21) which forms a closed loop, secured to the return, on the one hand, and to the swinging arm (12) of the receiver member, on the other hand. The pulling action of the cable gives rise to the rotation of the swinging arm, placed in articulation on the outside support (13), ensuring the fastening of the receiver member to the reveal of the window, the end of the swinging arm is provided with a rod sliding in a slideway which, being fixed to the shutter, forces the latter into an "open-closed" swing.
