Patent ID: 7959195

Claim:
A lock arrangement comprising a first jaw component pivotally moveable about a pivot axis, a second jaw component, a releasable clamping arrangement that applies a clamping load to rigidly secure the second aw component to the first jaw component to form a substantially rigid pivotable jaw assembly, an actuator arrangement operable to drive the jaw assembly, as a single unit, between a lock position and an unlock position, wherein in the event of failure of the actuator arrangement, the clamping load can be removed by operation of the releasable clamping arrangement to release the second jaw component from the first jaw component and allow movement of the second jaw component to an emergency release position independently of the first jaw component, wherein when released from the first jaw component by operation of said releasable clamping arrangement, the second jaw component is pivotable about an axis other than the pivot axis.
