Improvements in door handle mechanisms
A mechanism, for a door handle, comprising a cam assembly including a resilient biasing element 38, e.g. a spiral spring, with a hooked end (56, fig.7) engaging a spigot 36, and a cam member 40 having two stop members (74, 76, fig.8-10). The stop members are laterally offset such that the stop members extend out of the plane of the main cam into a laterally spaced parallel plane. The stops are preferably spaced from the resilient spring to reduce wear. The cam stops limit rotation of the handle and preferably abut the spigot 36. The spigot is preferably square and the hooked portion of the spring abuts planar surfaces of the spigot.
