A hinge (11) comprising a bobbin (12) and an arm (13), the bobbin having a peripheral flange (14)at each end of a cylindrical portion (15) and being formed with two parts (12A, 12B) split longitudinally with internal surfaces (16) enabling the bobbin to be assembled non-rotatably around a rectangular-section frame member (17), there being holes (18) in the bobbin parts for securing them to the rectangular-section frame member, and the arm (13) having a first bore (19) rotatable round the cylindrical portion (15) of the bobbin and a second bore (20) parallel to the first bore and in which a round-section frame member (21) can rotate, the arm being split between the two bores and beyond at least one of the bores in a plane containing the axes of the bores enabling the arm (13) to be assembled around the bobbin (12) and round-section frame member (21), there being holes (22) in the arm (13) intermediate the bores (19, 20) and perpendicular to the said plane for securing the arm on the bobbin and the round-section frame member. |
