Handle assembly
A handle assembly, for a door locking mechanism, comprises a handle connected to a housing via a rotational member e.g. a spindle; the housing 12 receiving and storing the handle, preferably flush with an outer surface and a mount 20 for receiving the rotational member; a handle release assembly to move the handle from a stored inoperable position into a released operable position, and a translation mechanism to move the handle rotatably about and axially along an axis normal to a planar surface of the housing. The translational mechanism is preferably a cam system with a cam profile on the handle e.g. handle pins, and a cam surface on the housing. The release mechanism may be a biased push latch system (Fig 5) located in a hole 26 underneath the handle, and comprising a piston wedge and a cam profile in which a linking rod member moves from stored to released positions. In use the handle is push down against the push latch, the rod moves in the cam profile and with the bias moves the latch pushing the handle outwards. A second spring may be provided to bias the handle inwards.
