ABSTRACT:
A braking mechanism is disclosed for installment between the frame and the casement of a door or window including those that are movable about two axes (combined tilting-rotation action) includes a tube that has at the face a guide opening for passage of a piston rod which slideably extends in the tube, with the guide opening being formed by a formed body secured in the tube. The formed body has a conical shape and has braking surface tapering in direction of the guide opening and in engaging contact with a conical braking body which completely surrounds the piston rod and through which the piston rod moves. The braking body is tapered complementary to the braking surfaces of the formed body and is spring-loaded against a stationary abutment. At least one damper element made from elastic material is lodged between the piston and the stationary abutment within the tube.
