Joint hinge for doors, especially joint hinge with three hinge members

摘要

In a three-membered joint hinge, the outer hinge members may be fixed to the door frame and the middle hinge member to the door wing. At the same time, at least the hinge sleeve of the hinge member associated with the door wing has an eccentric bush which can be fixed non-rotatably to the said hinge member and which comprises a hinge pin engaging into the hinge sleeves of all the hinge members. To allow an alignment of the door wing, without the joint hinge having to be dismantled for this purpose by removing the hinge pin, the hinge pin has a non-round cross-section connected positively with rotational take-up to the eccentric bush of the middle hinge member and is provided at one end with a receptacle for an adjusting tool.
