The mechanism is fixed to one edge of a door or window leaf. It connects the door from a hinging into a sliding one movable sideways in guides at the top and bottom of the frame after unlocking. - It comprises a driving rod to which a pin is fixed, moved by handle in the lengthwise direction. The pin engages with a rotary cam fixed by a spindle to one end of an arm, whose other end is coupled to a roller. Movement of the rod, cam and arm brings the leaf into a position in which it can slide in the guide or be locked to the frame. |
