A hinge comprising a first leaf (12 Fig 1) for connection to a first object and a second leaf (14 Fig 1) for connection to a second object, a pivot pin 58, and a convex bearing 60 defining an opening for receiving a portion of the pivot pin, the first and second leaf including a respective first and second retaining portions surrounding a first and second portion of the pivot pin for rotation of the leaves about an axis of rotation defined by the pivot pin, the axis of rotation being rotatable about the bearing. Preferably the bearing is a ball bearing. There may be a first bearing bush 63 which has an internal diameter greater than that of the pin allowing angular movement of the pin about the ball bearing 60. Second and third bearing bushes 62 64 may also be provided. Preferably the bearing sits within the middle body of a three body hinge, the hinge may also have three pivot points (22 30 54 Fig 4). |
