ABSTRACT:
Over-center hinge (10) whose jamb-related part is in the form of a supporting arm (16) coupled by two links (18 and 20) to the door-related part (14) in the manner of a four-joint hinge. In the linkage end of the supporting arm (16) there is provided a thruster (26) whose one end is mounted so as to be longitudinally displaceable under resilient bias and rotatable about the fixed pivot (28) of one of the hinge links (18), and whose other end, which is provided with a cam (42-44), is urged against a crosspiece (36) in the supporting arm (16). By way of studs (50) on the other hinge link (20), which are guided by a cam (48), the thruster (26) is swung during the hinge movement, while in the vicinity of the closed position a ramp surface (44) cooperates with the crosspiece (36) in such a manner that the thruster (26) is swung towards the second hinge link (20 ) and exerts a force thereon acting in the closing direction.
