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 cover for a wheel or hub may be rotationally attached and removed from the hub by hand due to a mounting clip on the cover defining a space for a single lug nut and a tangentially oriented entryway.

Abstract: A method and system for mounting decorative wheel covers uses an adaptor or the like for frictionally engaging the outer periphery of one or more standard lug nuts, without affecting the seat of the lug nut to the wheel. The adaptor further includes a threaded member cooperating with apertures in the wheel cover or similar structure for attaching a decorative wheel cover. Specialized bushings may be used with the adaptors to provide a universal mounting system adaptable for use with a plurality of differently-sized lug nuts. Unitary or multiple-piece wheel covers may be used in conjunction with the mounting adaptors provided. Various ways of inhibiting or preventing relative rotation between wheel cover elements and a wheel are provided in the different embodiments.
