Abstract

Central closure for sliding windows, essentially characterized by the fact that it consists of a laminar support that with two side plates forms the box, whose support has two walls, rear and intermediate, provided with separate holes through which a latch formed is displaceable by a shank provided with a pushbutton that is accommodatable between the intermediate wall and a front wall, whose shank is through an orifice of an elastic plate that at one end is attached to the support and which is pushed by means of a spring and maintained oblique with respect to the axis of the rod, so that the hole of said plate is also supported inclined by two opposite edges of its edge against the rod, which is thus maintained in the insertion position in the strike, whose elastic plate is bent by its opposite end where it presents a pin inserted in a blind hole of a key that is displaceable on said pin and is requested to the protruding position of the front wall by a return spring, all this so that, by means of a pressure applied to the key, the inclined plate is placed with its section provided with the hole in position perpendicular to the rod and the edges of such hole they separate from the rod, defining a clearance that allows the rod to move towards the outside to the open position, caused by such movement by a return spring that is housed in a blind hole of the button and rests between the bottom of such hole and the middle wall of the support.
