A hinge (1) for locating between two members which are to be folded together and opened apart, comprises a pair of parallel trunnions (2,3) interconnected by spaced webs (4). Each trunnion has axially-spaced cylindrical portions (5) of larger diameter than coaxially-arranged intermediate cylindrical portions (6). The hinge is made of a stiffly resilient plastics material having self-lubricating properties and is mounted between the members with the trunnions located rotatably in respective moulded sockets in the respective members. The webs (4) pass through openings in the end faces of the members and permit them to move in their own planes as well as to rotate during their movement from folded-together positions, to the positions they occupy when they are opened apart. The hinge provides a tidy, clean appearance to the members where they are hinged together. |
