The present invention discloses a lock system, comprising a lock assembly that includes a hasp and an interlock mechanism detachably engaging with the hasp. Further included is a latch system that latches the interlock mechanism in a lock position.

A multifunction securing mechanism for a compartment closable by a door and includes a key cylinder, a latching assembly which may be a two-point latching assembly movable between a latching and an unlatching position, a rotatable member configured for a lazy-cam function connecting the key cylinder and latching assembly, at least one catch located on a surface adjacent the outside of the door, and a bar pivotally mounted to the outside of the door and movable between a first closed position and a second opened position. A first release mechanism is located on an interior side of the door for changing a positon of the latching assembly, and a second release mechanism is located on the interior side of the door for changing a position of the bar, both for allowing a user to open a latched and secured door from the inside.

A handle system and mechanism for a vehicle rolling door is disclosed. The system has an inside handle with a handle portion and a shank portion. The system also has a selectively rotatable swing plate. The swing plate selectively contacts the shank portion of the inside handle to assist in opening the door. The swing plate can also contact a stop plate. An outside handle is also provided.

A lock mechanism is provided for use with a door assembly. The lock mechanism includes a lock bracket configured to connect to a door or hatch; a lock pin can be selectively moved between an engaged position in which the lock pin engages the lock bracket and a disengaged position in which the lock pin does not engage the lock bracket; and a linkage assembly connected to the lock pin and configured to be actuated to reversibly move the lock pin between the engaged position and the disengaged position, and a door or hatch release device can switch the lock pin from the engaged position to the disengaged position if the door or hatch release device is actuated after the linkage assembly has moved the lock pin into the engaged position.

A vehicle door includes a door panel slidably operable between a secured position within a door aperture and a staging position partially distal from the door aperture. A latch is engaged with a striker path during operation of the door panel between the secured and staging positions, and is selectively disengaged from the striker path to define open and closed positions of the door panel when the door panel is in the staging position.

An internal release mechanism for a truck roll-up door closure to a vehicle compartment includes a lift arm disposed on the roll-up door inside the vehicle compartment having a stowed position and a deployed position, a first release mechanism coupled to the lift arm operable to bypass a door lock disposed outside the vehicle compartment in response to the lift arm being moved by an occupant inside the vehicle compartment from the stowed position to the deployed position, and a second release mechanism coupled to the lift arm operable to clear a mechanical door latch disposed outside of the vehicle compartment also in response to the lift arm being moved from the stowed position to the deployed position.
