Lock mechanism using one-way valve to lock piston
First Claim
1. A lock mechanism for locking at least one door of a container in a closed position, the lock mechanism comprising:
- a housing;
at least one lock member at least partially enclosed within the housing, the at least one lock member comprising a first latch hook configured to engage a latch assembly bar on an exterior of the at least one door to lock the at least one door of the container in a closed position, wherein the lock member is removable from the at least one door;
a latching mechanism coupled to the at least one lock member, the latching mechanism comprising;
a fluid chamber configured to hold a fluid,a piston slidably housed within the fluid chamber, anda valve coupled to the fluid chamber and configured to be in one of two states, the two states including an open state where fluid can flow through the valve in two directions to allow the piston to be moved in two directions, and a closed state where fluid is inhibited from flowing through the valve in at least one direction to prevent the piston from moving in at least one direction; and
a lock circuit at least partially enclosed within the housing, the lock circuit comprising;
memory, anda lock controller coupled to the memory and the latching mechanism and configured to receive commands related to the operation of the lock mechanism, wherein the lock controller is configured to cause the latching mechanism to be in one of the two states in response to the received commands.

Abstract
A lock mechanism for locking at least one door of a container in a closed position includes a housing, at least one lock member at least partially enclosed within the housing, the at least one lock member comprising a first lock member configured to engage a first portion of a container to lock at least one container door in a closed position, and a latching mechanism coupled to the at least one lock member. The latching mechanism includes a fluid chamber configured to hold a fluid, a piston slidably housed within the fluid chamber, and a valve coupled to the fluid chamber and configured to be in one of two states, the two states including an open state where fluid can flow through the valve in two directions to allow the piston to be moved in two directions, and a closed state where fluid is inhibited from flowing through the valve in at least one direction to prevent the piston from moving in at least one direction. The lock mechanism further includes a lock circuit at least partially enclosed within the housing, the lock circuit including memory, and a lock controller coupled to the memory and the latching mechanism and configured to receive commands related to the operation of the lock mechanism, wherein the lock controller is configured to cause the latching mechanism to be in one of the two states in response to the received commands.

12. A lock mechanism for locking at least one door of a container in a closed position, the lock mechanism comprising:
-
lock member means comprising at least one hook member configured to removably engage a latch assembly bar attached to an exterior of a container door in a closed position; means for slidably coupling the at least one lock member of the lock member means to a portion of the lock mechanism; latching means coupled to the slidably coupling means and configured to be in one of two states, the two states including an open state and a closed state, the latching means for allowing the at least one lock member of the lock member means to be moved in two directions when in the open state, and for preventing the at least one lock member of the lock member means from moving in at least one direction when in the closed state, wherein the latching means comprises a one-way valve configured to allow fluid to flow in only one direction when the valve is in the closed state; means for receiving commands related to the operation of the lock mechanism; and means for controlling the latching means to be in one of the two states in response to the received commands. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
