<p>A hinge (10) comprising an elongate base (11) and first and second hinge plates (12, 13) pivotally mounted on said base (11) for carrying hinged structures (21, 22). The base (11) has two parallel spaced holes (14, 15) for receiving two parallel spaced pivot pins (16, 17) that extends at right angles to the length of the base (11) across the width of the base. Each of the hinge plates (12, 13) has an upstanding portion (23) extending in a direction extending along the length of the base (11) and encompassing a part of the perimeter of the base (11). Flange means (24) are provided for fixing the hinge plate (12, 13) to the hinged structures (21, 22). Each hinge plate (12, 13) has two aligned holes (27) that align with one of the holes (14,15) in the base (11) for receiving one of said pivot pins (16, 17) thereby enabling each hinge plate (12, 13) to pivot relative to the base (11) about a respective one of the pivot pins (16 or 17). To enable the hinge (10) to open through 180°, the base (11) has a pair of upstanding flanges (30) that have two parallel spaced holes (31, 32) for receiving pivot pins (40, 43) of two intermediate members (36, 37) that are provided to lift the hinge pins (16, 17) through an arcuate path to clear the top of the base (11).</p> |
