Abstract
Device for the regulated closing of doors essentially characterized by consisting of a pneumatic cylinder whose interior is traversed by a piston provided with an axial rod fixed at its other end to the spring holder box that determines the tension made on the door so that when it is fixed in the door frame by means of a support piece in the form of a square laminar square at right angles to the spring-carrying box and in the body of the door itself door the free end of the cylinder is transmitted to the door an adjustable force according to the tension communicated to the main spring contained axially in the spring holder box and tensioned by the action of a square section axis arranged axially in the box and inside the shaft spring that is externally actuated by means of a suitable wrench that determines the rotation of two pieces located at opposite ends of the shaft in a square section so that their angular rotation determines the axial compression of the spring by means of an auxiliary piece integral with the shaft and which determines the rotation of the lower end of one end of the spring with the spring holder being supported by a support piece that fixes it to the door frame.
