Abstract:
1. A lock, comprising: a latch movable between a first position and a second position; a first locking mechanism operatively coupled to the latch; a second locking mechanism operatively coupled to the latch; and at least one locking head operatively coupled to the first locking mechanism and the second locking mechanism, wherein the at least one locking head is positionable between a closed position and an open position and configured for positioning in the open position when the latch is in the second position; a control plate operatively coupled to the latch and configured for movement in a direction substantially perpendicular to the movement of the latch; and at least one blocking plate operatively coupled to each of the at least one locking head; wherein the at least one blocking plate is movable in a direction substantially perpendicular to the movement of the at least one locking head between a retained position and an ejected position; wherein the first locking mechanism and the second locking mechanism are each configured to independently cause the movement of the control plate in the direction substantially perpendicular to the movement of the latch, and wherein such movement of the control plate is configured to move the latch into the second position and to move the at least one locking head into the open position; and wherein wherein the at least one locking head comprises a locking area formed within the at least one locking head and positioned to surround at least a portion of the latch when the latch is in the first position so as to maintain the at least one locking head in the closed position.
