FRONT LOADED CYLINDER FOR DOOR LOCKSET

摘要

A door lockset 20 includes a front loaded cylinder lock 75 which is assembled with an insert 64 within a knob 62. Cylinder lock 75 includes a locking bar 104 which is biased toward a central opening 83 formed through a body 76 of the lock. A plug 80 is located within opening 83 and is rotatable therein. A removal key 108 is formed with a slot 240 which is alignable with a plug slot 109 when the key is inserted into a key slot 113 of the plug. Plug 80 is thereafter rotated within opening 83 to align locking bar 104 with plug slot 109 and key slot 240 whereby the bar moves into the slots under the biasing action of a spring 106. Cylinder lock 75 can then be removed from the front of insert 64 and knob 62. A reverse process is followed to load cylinder lock 75 into opening 238 and to retain the lock with insert 64.
