A checked lift-off hinge assembly (10) including a pair of hinge leaves (11,12) pivotally connected to one another so as to be separable by relative movement along the axis of the pivotal connection, a torsion spring (40) mounted on one of said hinge leaves, the torsion spring extending towards and being co-operable with one or more reaction members (19) on the other hinge leaf to provide a checking force for resisting relative pivoted movement between the hinge leaves (11,12), said one hinge leaf including positional displacement means operable on said torsion spring (40) for moving the torsion spring to relieve spring pressure on the reaction members (19) to thereby enable axial separation of the hinge leaves (11,12). <IMAGE> |
