Dual Action Detent For Tamper Resistant Lever Lock Mechanism
US Patent:
2002017, Nov 28, 2002
Filed:
May 24, 2001
Appl. No.:
09/864566
Inventors:
Daniel MacMillan - Littleton CO, US
International Classification:
E05B025/02, E05B025/00
US Classification:
070/355000
Abstract:
A lever lock apparatus having a sliding bolt, a detent mechanism for locking the bolt against sliding movement and a plurality of levers. When using the appropriate key, the detent moves to allow the bolt to be slid to a locked or unlocked position. When the lock is under attack, and an inward force is applied to the bolt, the detent moves so as to maintain a detent fence away from the levers. Keeping or moving the fence away from the levers impairs the ability to pick or otherwise attack the lock.
