A system for sensing the security of a container includes a housing, at least two lock members coupled to the housing, the lock members configured to couple to first and second portions of the container to lock at least one container door in a closed position, a signal generator configured to generate a first signal and couple the first signal to the first portion of the container, the generated first signal having a known profile, and a lock controller configured to cause the signal generator to generate the first signal upon occurrence of a trigger event. The system further includes a signal detector configured to receive a second signal, the second signal resulting from the first signal, and a signal analyzer configured to analyze the second signal to determine a profile of the second signal, retrieve stored data representing a signal profile indicative of the lock mechanism being coupled to the first and second portions of the container, compare the profile of the second signal to the stored signal profile, and determine that a relationship between the lock mechanism and the container has changed based on the comparison.
Abstract:
A lock mechanism for locking at least one door of a container in a closed position includes first and second members slidably coupled to each other to move relative to each other, a latching mechanism configured to prevent the two members from moving relative to each other in at least one direction when the latching mechanism is in a locked state, and first and second lock members, each of the lock members including a first end and a second end. The first ends of the first and second lock members protrude through the body. The second end of the first lock member is coupled to the first member of the locking mechanism and the second end of the second lock member being coupled to the second member of the locking mechanism. The first ends of the first and second lock members are configured to engage portions of the container to lock the at least one container door in a closed position. The body is sized and disposed to support the first and second lock members to prevent rotation of the first and second lock members about points where the first and second lock members are attached to the first and second members of the latching mechanism. The lock mechanism further includes a lock circuit at least partially enclosed within the body. The lock circuit includes a lock controller coupled to 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 the locked state in response to the received commands.
Abstract:
A door has a doorknob, and is hingedly mounted in a door frame having at least one vertical member. The door is capable of selective rotational movement between a closed configuration and an open configuration. The door has a first side and an opposed second side. The first side is oriented in a direction toward which the door opens. A barricade bar includes a flange member for selectively engaging the doorknob to prevent the separation of the flange member from the doorknob. The barricade bar also includes a frame member for coordinate engagement with the at least one vertical member. The frame member is rigidly coupled with the flange member. The barricade bar can be oriented adjacent the second side of the door so that the frame member engages the vertical member and the flange member engages the doorknob to prevent the opening of the door.
Abstract:
A locking flange (200) for securing an airline cart (100) can include a hook shaped flange that wraps around a pull bar (130) of the airline cart, a pair of apertures (204) on opposing sides of the hook shaped flange where the apertures reside below the pull bar when the hook shaped flange is placed on top of the pull bar, and a locking mechanism (250) for insertion within the apertures once the flange is placed on top of the pull bar. The locking flange can project below a top plane of a door (102) of the airline cart. The locking flange can be made of metal such as high tensile steel. The locking mechanism can include a cylinder having a head (252) on one side and an aperture (256) on an opposing side for placement of a lock (502) through the aperture of the cylinder.
Abstract:
A lockable strike for walk-in cold rooms includes a housing that includes a recessed well with openings positioned on opposing sides thereof to accept a locking device therethrough and a deadbolt moveably engaged therein to reciprocally move along a path of travel between an extended position and a retracted position with respect to the housing; and a knob rotatably mounted within the recessed well and having an opening through a handle thereof positioned relative to the openings in the housing to further accept the locking device therethrough thereby preventing the rotation of the knob in a first position, wherein the handle can engage the locking device when it is inserted through the openings in the housing thereby preventing the rotation of the knob in a second position, and the knob is in communication with the deadbolt to move the deadbolt between the extended position and the retracted position when the knob is rotated.
Abstract:
A lock box assembly for enclosing and protecting a plastic security seal on the latch assembly of the door on a cargo container or trailer. The lock box includes first and second box members that together form an enclosure for the hasp assembly that holds the seal. Cooperating latch arm slots in the sides of the box members capture the latch arm, thereby securing the lock box to the latch assembly and preventing access to the seal. Aligned holes in the sides of the box members receive a lock pin. This configuration provides a lock box that is simple in design and easy to attach and remove using any conventional lock pin. The box is secured to the latch assembly by capturing the latch arm in the slots, eliminating the need for any structure to pass through the hasps, leaving the seal undisturbed.
Abstract:
A lock guard is provided which is particularly well suited to protect a padlock employed to secure a stanchion lever securing one or more doors of a cargo container, trailer truck or moving van. The lock guard includes an interior locking tab with a vertical opening through which a hinged leg of a padlock shackle extends when the unhinged leg of the shackle is passed through an opening in a component of the stanchion door and the shackle is closed by abutting it against an abutment on the underside of the roof of the guard. The lock guard, which provides a protective housing or shield for the shackle of the padlock when the padlock is in its installed locking position, is particularly compact thereby minimizing access of cutting tools to the padlock shackle.
