The barrel-shaped surface may either be integrally formed on a pin 11 or be provided by a sleeve (21), Fig. 4 (not shown), fitted to the pin. The bore of the sleeve (21) may be eccentric with respect to the outer surface of the sleeve to facilitate adjustment of the hinge. The bore 17 may be provided with a cylindrical sleeve (20), Fig. 3 (not shown) which may also be provided with an eccentric bore. The combination of the hinge 16 and pivot assembly (22) is suitable for gravityoperated self-closing doors. In such a door the hinge and pivot assembly are offset from the door frame by bending the mounting plates thereof, Figures 7 and 8 (not shown). In an alternative embodiment, Figure 6 (not shown), the hinge taking the horizontal component is in the form of a knuckle joint, the central knuckle of which has a cylindrical bore (33) therethrough which accepts the barrel-shaped surface (37) of the pin.
