Abstract:
1. A safety device system preventing false maneuvers of sliding window and door frames which comprises: a fixed frame and a mobile frame of a window or door, which bear, in a position corresponding to respective facing vertical uprights, a stationary striker and a catch, said catch configured to be displaced vertically between an operative position in which said catch engages with said striker for blocking said mobile frame with respect to the fixed frame in a closing condition, and an inoperative position corresponding to the disengagement of said catch from said striker to enable opening of said mobile frame, and safety means to prevent displacement of said catch to said operative position until said mobile frame is re-closed with respect to the fixed frame, said safety means including an arrest and an elastic means received in a cavity of a slide, said slide comprising a plurality of walls bounding said cavity, said arrest displaceable within said cavity of said slide and with respect to said mobile frame, against the action of said elastic means, from an advanced position in which said arrest blocks said catch in said inoperative position, to a retracted position in which said arrest enables displacement of said catch into said operative position, and a thrust member adjustably connected to said arrest and projecting from said mobile frame to bear upon said fixed frame so as to move said arrest from said advanced position to said retracted position following upon closing of said mobile frame relative to said fixed frame, wherein said slide is adjustably movable from a first position to a second position within a seat of said mobile frame in a direction orthogonal to the direction of the displacement of said arrest between said advanced and retracted positions, and wherein said catch comprises an upwardly projecting appendage, said slide comprising a slot in a wall of said plurality of walls to allow displacement of said appendage therein into said operative position when said arrest is in said retracted position.
