Improvements in door handle mechanisms
A door handle mechanism comprising a cam assembly including a resilient biasing element, e.g. a spiral spring, with a hooked end (56, fig.7) engaging with a planar surface 48 of a spigot 36. Also claimed is a door handle mechanism comprising a cam assembly including a resilient element, a spigot, wherein the cam assembly includes a cam member 40 with at least one stop member (74, 76, fig.8-10) which extend out of the plane of the main portion of the cam, e.g. the stops lie in a second plane spaced from and parallel with the main plane of the cam member 40. The stops limit the rotation of the handle and preferably abut the spigot 36 which may be square. The offset stops are preferably spaced from the spiral spring.
