Abstract
A cylindrical lever type lock is disclosed having first and second spindle housings telescopically receiving an outer and inner spindle, respectively. The outer and inner spindles both have a protruding plate formed on one end for urging a bracket to pull a pole and therefore to open a door. An annular ring rotatably secured on an engaging pin is urgeable by a bar assembly from inside of the door to lock the outer spindle relative to the first spindle housing. An engaging pin, which is rotatable by a key, unlocks the blockage between the outer spindle and the first spindle housing. A pair of plates each having a pair of cutouts, a pair of oblique cutouts and a pair of triangular protrusions are securely mounted on opposite sides of the door to firmly support the first and second spindle housings in position.
