Abstract

Hinge-brake for doors, characterized by being made up of a cylindrical body from which the blades protrude to fasten the hinge to the door and to the frame thereof and which has the braking device inside it, also constituted by its own cylinder filled with a liquid of appropriate density whose axis coincides with that of the hinge and which is divided into two longitudinal chambers by a rod of square section fixed to the inner part of this cylinder, by the shaft and by a blade or lever integral with the same axis, having prevented in the rod two perforations or cylindrical channels, one of them equipped with a sealing ball that allows the passage of liquid in one direction and the other faced with a conical tip screw through which the opening of the valve is regulated. admission of the liquid contained in the device, thereby achieving that, simultaneously with the rotation of the axis of the hinge, and by virtue of the lever or a spade that is solidary, at each turn of the door (transmitted to that axis by the existing fit between the clamping blade and the square sections established on both ends of the shaft) the preheated liquid is driven, through the perforations or channels also mentioned and under the conditions indicated, from one to another of the longitudinal chambers in which the body or device itself is divided, whose base is divided into two sectors of different height so that, at a certain time, cause the mismatch between the spade attached to the axle and this base, with the consequent loss of liquid pressure and the automatic abandonment of the braking function on the closing of the door, in turn determined independently by the spring or similar element that has been applied to the effect .
