Title:
LOCK SET FOR DOOR PANEL
Document Type and Number:
Japanese Patent JPS58204277
Kind Code:
A
Abstract:
A lockset for use on any one of various door panels of different thickness and hinged on a door frame includes a latchbolt adapted to project into a holder on the door frame and to retract therefrom. Inner and outer knobs are rotatably mounted on opposite sides of the door panel to rotate about a common axis and relative to inner and outer escutcheons held against the panel of whatever thickness. Inner and outer spindles are engaged by the knobs and turn in the escutcheons. The spindles rotate a rectangular tube interengaged with the latchbolt for all axial positions of the knobs to provide retraction thereof. A push button in the inner knob, when latched in a depressed position, secures the outer knob against rotation by a nonrotatable engagement with the inner escutcheon. Rotation of the inner knob releases the push button from the depressed position and frees the outer knob for rotation. An aperture in the outer knob allows insertion of an emergency tool to release the push button from the depressed position.
