Lever handle controller

摘要

A free-wheeling lock mechanism for operating a door latch includes a body, a handle, a lock and a split shaft having two halves rotationally connected together along the shaft axis. One half of the shaft is connected to the handle and one half extends from the body to operate the door latch. The two halves of the shaft may be coupled and uncoupled via a shaft lock movable perpendicular between locked and unlocked positions. In the unlocked position the shaft lock connects the two halves of the shaft to rotate together when the handle is turned. In the locked position the shaft lock disengages the two halves of the shaft to rotate separately and allow the handle to free-wheel without operating the door latch.
