RAPID-CHANGE LOCK
Document Type and Number:
WIPO Patent Application WO2004101917
Kind Code:
B1
Abstract:
A changeable lock assembly (10) suitable for re-keying a lock without disassembly of the lock. The assembly includes a housing (12) having a bore (14) therein, and a plug (16) rotatably mounted in the bore (14). The plug (16) includes a longitudinal axis (50) and a keyway (24). The keyway (24) is adapted to receive at least a first user key (30) and a second user key (62). The lock further includes a change member (56) movable within the lock between a first position to a second position. The change member (56) can move solely in response to operation of the second key (62). Thus, when the change member (56) is in the first position, the first key (30) operates the lock, and when the change member (56) is in the second position, the first key (30) does not operate the lock. The lock assembly can also employ a change tool (64) that, when inserted into a change slot (88), can move a change ball (56) from the second position back to the first position.
