Abstract: A latch assembly for a cargo door assembly that accommodates for dimensional and structure variations is cargo door assemblies to ensure a secure latching mechanism. The latch assembly uses a two piece design that includes a handle unit and a separate plunger unit to enable its use with cargo doors of varying thickness. The latch assembly also uses spacers to selectively position a plunger carriage within a plunger housing to selectively adjust the position of an extensible plunger supported by the carriage relative to the door frame, which ensures that the plunger properly engages the door frame and securely holds the cargo door closed.

Abstract: An electromechanical travel bar lock assembly disables the flow of power to the power drive that moves a RV slide-out room between the traveling position and the deployed position. The assembly includes a bar for removably securing between the wall of the vehicle and the facer board of the slide-out room to prevent the room from moving. The travel bar is provided with an actuator that actuates, directly or indirectly, a switch means incorporated into the circuitry of the power drive so that power is not permitted to flow from its source to the drive, and the slide-out room cannot be moved when the travel bar is positioned between the vehicle wall and the facer board. The actuator, switch, and circuitry may embody any one of several different configurations and/or combinations.

Abstract: A wireless DC control device including a radio frequency transmitter, receiver, and switching circuit controls the current and polarity of the current that is used to power DC motors used in mobile living quarters. The control device has particular application for controlling the extension and retraction of slide-out rooms in a mobile living quarters.
