Lockable carrier hinge assembly

Abstract

A carrier hinge assembly is used to suspend adjacent hinged panels from a track. The assembly has a carriage (30) which travels along the track, and a hinge (34) dependent from the carriage (30). The hinge is formed by a hinge pin (35) having an upper portion (39) threaded into a boss (32) on the carriage (30), and hinge leaves (36, 37) which are pivotable about the hinge pin (35). The hinge leaves (36, 37) are fixed, in use, to opposing edge faces of the panels. The height of the panels may be adjusted by rotation of the hinge pin (35). A locking mechanism includes a retractable lock tongue (40) located in an axial slot (42) in a stop (38) at the bottom of the hinge pin (35). The lock tongue (40) is biased by spring (50) to engage an axial slot (58) in hinge leaf (37), to key the hinge pin (35) to the hinge leaf (37) and prevent relative rotation.
