Abstract
Hinge (1) with one pivoting (2) and one fixed (3) hinge leaf, with a physical hinge axle (7) similar to a hollow cylinder which is common to both hinge leaves (2, 3) with an imaginary mathematical axis (4). The hinge axle (7) is connected unmovably to the pivoting (2) hinge leaf and mounted rotatably on a journal bearing (5-1, 5-2), the body of which journal bearing is connected rigidly with the fixed (3) hinge leaf. In the hinge axle (7) a spiral torsion spring (8) arranged, the first (8-1) of whose two ends is connected unmovably to the hinge axle (7) and the second (8-2) of whose two ends is connected via a worm-gear unit consisting of a worm wheel (9) and endless screw (6) to the journal-bearing body of the journal bearing (5-1). The worm wheel (9) is arranged in the journal bearing (5-1) to rotate around the axis (4) of the hinge axle (7) and is fixed permanently to the second (8-2) of the two ends of the spiral torsion spring (8). The adjustment of the worm wheel (9) and consequently the adjustment of the tension of the spiral torsion spring (8) takes place by turning the endless screw (6) which is arranged in the fixed part of the journal-bearing body of the journal bearing (5-1) and into which the teeth (9-10) of the worm wheel (9) engage.
