Patent attributes
A lock includes inside and outside handles mounted rotatably on a lock housing unit, a key-operated lockset mounted to the outside handle, a rotary knob mounted to the inside handle, a handle-connecting rod co-rotatable with the inside handle, a driven seat co-rotatable with the handle-connecting rod, a lock-connecting rod interconnecting the lockset and the rotary knob, and an engaging plate disposed movably within a slot in the driven seat. The lock-connecting rod is rotatable to move the engaging plate between a connection position whereat the engaging plate projects from the driven seat so as to allow for co-rotation of the outside handle with the handle-connecting rod, and a retracted position whereat the engaging plate is retracted into the driven seat so as to prevent co-rotation of the outside handle with the handle-connecting rod.
