The hinge has an axle (1) fitted in an installation sleeve (2), where one end of the axle is movable in height for non-rotatable fixing of the sleeve in a part of a door leaf or a door frame, and another end of the axle is rotatably placed in a box. The axle extends by the former end from the installation sleeve and by the latter end in the box in a mounted state of the door leaf in the door frame. A helicoid spring (3) exerts force on the axle to push the axle by its latter end outside the installation sleeve. |
