Abstract:
1. A lock configured for operation between a locked configuration and an open configuration, comprising: a body comprising a first surface with a toe receiving hole formed in the first surface; a shackle comprising a toe and a heel having a longitudinal axis and extending into and retained within the body; a first locking mechanism comprising a latch plate operatively connected to the shackle, wherein the first locking mechanism is configured for operation between a locked position in which the latch plate restricts rectilinear movement of the shackle along the longitudinal axis of the heel of the shackle, and an unlocked position in which the latch plate is spaced away from the shackle to permit rectilinear movement of the shackle along the longitudinal axis of the heel of the shackle; and a second locking mechanism comprising at least one clutch operatively connected to the shackle and configured for operation between a closed position in which the at least one clutch restricts rectilinear movement of the shackle along the longitudinal axis of the heel of the shackle, and an open position in which the least one clutch is positioned so as to permit rectilinear movement of the shackle along the longitudinal axis of the heel of the shackle; wherein the at least one clutch comprises a substantially cylindrical member having a longitudinal axis and a bore through the longitudinal axis divided into a lock-open zone and a locking zone by a blocking ring extending from an interior surface of the at least one clutch; wherein at least a portion of the heel of the shackle is positioned through the bore of the at least one clutch; wherein the lock is configured to be in the open configuration as a result of rectilinear movement of the shackle along the longitudinal axis of the heel of the shackle when the first locking mechanism is in the unlocked position; wherein the lock is configured to be in the open configuration as a result of rectilinear movement of the shackle along the longitudinal axis of the heel of the shackle when the second locking mechanism is in the open position; wherein the lock is configured to be in the open configuration when either of the first locking mechanism is in the unlocked position or the second locking mechanism is in the open position and the shackle is moved rectilinearly along the longitudinal axis of the heel of the shackle; and wherein at least a portion of the toe is at least partially surrounded by the toe receiving hole when the lock is in the locked configuration.
