Abstract

Closing and opening device for sliding doors and windows, of the type in which the closing is produced by a slight descent of the moving leaf of the door or window with respect to its normal position of movement, characterized in that it comprises an upper lock, constituted by a slip latch, known per se, on which a drive cam or nut acts, connected to the handle of the door or window and capable of turning on itself when said handle of the door or window is actuated, at the same time articulated said nut to a vertical bar capable of moving vertically upwards or downwards and which in turn is articulated by its lower end to a lower lock, constituted essentially by an angular piece, rotating around its vertex and provided at the end of an arm of a sliding joint that transmits the rotational movement of the angular piece, and therefore the displacement vertical bar and the rotation of the nut, to a horizontal pusher rod, adapted to project perpendicularly from the front edge of the movable leaf at the moment of opening it, resting against a corresponding anchor plate applied on the sleeper's edge. The door or window, in order to produce an opening movement of the moving leaf by reaction against the end plate, this movement which contributes to the necessary lifting of the movable leaf of the door or window for opening it.
