Abstract

Claims (16)

1. A shield device for a threaded fastener of a lock assembly, the lock assembly being adjustable between an inoperable state and an operable state and including a housing, the shield device comprising:

a barrier movably disposeable within the housing and configured to displace between a first position at which the barrier at least partially covers the threaded fastener and a second position at which the threaded fastener is generally accessible, wherein the barrier is completely disposed within the housing in the second position, the barrier being disposeable in the first position when the lock assembly is arranged in the inoperable state and being disposeable in the second position when the lock assembly is arranged in the operable state.

2. The shield device as recited in claim 1 wherein the lock assembly includes a member configured to adjust the lock assembly between the operable and inoperable states, the barrier being configured to couple with the member such that when the lock member adjusts the lock assembly between the operable and inoperable states, the barrier displaces between the first and second positions.

3. The shield device as recited in claim 1 wherein the lock assembly further includes a member movable between a first position and a second position, the barrier being configured to couple with the lock member such that movement of the lock member between the lock member first and second positions displaces the barrier between the barrier first and second positions.

4. The shield device as recited in claim 3 further comprising a link having a first end configured to connect with the lock member and a second end connected with the barrier, wherein movement of the lock member displaces the link such that the link displaces the barrier.

5. The shield device as recited in claim 4 wherein the link includes an elongated body and the barrier includes a plate attached to the body.

6. The shield device as recited in claim 3 wherein the lock assembly is disposeable in a first, operable state and alternatively disposeable in a second, inoperable state, the lock member is configured to adjust the lock assembly between the operable and inoperable states, and the barrier is configured to prevent access to the fastener when the lock is disposed in the inoperable state and to permit access to fastener when the lock assembly is disposed in the operable state.

7. The lock assembly as recited in claim 1 wherein the fastener is configured to mount the housing to one of a door and a door frame.

8. A lock assembly comprising:

a housing;

a fastener having a fastener head and a threaded portion;

a lock member movable between first and second positions; and

a barrier movably disposed within the housing and 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 being 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.

9. A shield device for preventing access to a fastener of a lock assembly, the fastener operable to connect the lock assembly to a door, the lock assembly including a housing, the shield device comprising:

a barrier disposable within the housing and configured to be displaceable between a first position at which the barrier at least partially covers the fastener to inhibit removal of the lock assembly from the door and a second position at which the barrier is spaced from the fastener such that the fastener is generally accessible to allow removal of the fastener to remove the lock assembly from the door, wherein the barrier is completely disposed within the housing in the second position; and

means for displacing the barrier between the first and second positions.
