Japanese Patent JPS5724468
Kind Code:
B2
Abstract:
Locking mechanism including a cam-actuated locking plate shiftable between engaging and nonengaging locking positions to lock an outside knob while the inside knob remains free to open the latching mechanism. When in its unlocked position, the plate is rotatable with the outside knob so that the door latch may be operated in a conventional manner. When shifted to its locked position, the plate fixed to the knob is moved by a cam mechanism into an engaging position with supporting structure such that the knob cannot be turned. The inside knob, however, remains free and operates the conventional latching mechanism without regard to the position of the locking plate.
