  • Patent number: 7918117
    Abstract: A lock assembly including a housing, a fastener that has a head, a lock member that is movable between a first position and a second position, and a barrier that is movably disposed within the housing. The barrier is displaceable between a first position at which the barrier at least partially covers the fastener head, and a second position at which the fastener head is generally accessible. The barrier is coupled with the lock member such that the barrier displaces from the barrier first and second positions when the lock member displaces between the lock member first and second positions.

  • Patent number: 7757524
    Abstract: A shield device is for fastener(s) of a lock assembly that is adjustable between inoperable and operable states, each fastener including a head and being removably engageable with a door to connect the lock assembly therewith. The shield device includes a barrier displaceable between a first position, where the barrier covers the fastener head to prevent removal of the fastener, and a second position where the fastener is accessible to permit removal. The barrier is disposed in the first position when the lock is in the inoperable state and in the second position when the lock is in the operable state. Preferably, the lock assembly includes a member that adjusts the lock assembly between the operable and inoperable states and the barrier is coupled with the member. As such, when the lock member adjusts the lock assembly between the two states, the barrier displaces between the first and second positions.

  • Patent number: 7007526
    Abstract: An electronic clutch assembly is for a lock system having a latch and first and second rotatable spindles, one being connected with the latch. A clutch is coupled with the first spindle, has a connective portion engageable with the second spindle, and is linearly displaceable along a first axis between a first position, where the connective portion is nonengaged with the second spindle and a second position where the connective portion is engaged with the second spindle. A cam is displaceable generally along a second axis extending generally perpendicularly with respect to the first axis and is configured to linearly displace the clutch between the two clutch positions. An electric actuator is operatively connected with the cam and configured to linearly displace the cam along the second axis such that the clutch alternatively couples the second spindle with the first spindle and uncouples the second spindle from the first spindle.
