Abstract: A combination pressure washer unit and slide out tray assembly for a carriage such as a bus, trailer or the like which transports racing cars or other equipment needing a pressure wash after use. The system includes a slide out tray assembly that is mounted in a compartment on the side of the carriage. A low profile pressure washer is mounted on the tray assembly floor and can be readily accessed through the compartment opening, slid out for use, and returned to its stowed position within the side of the carriage after use for transport.

Abstract: A locking mechanism for securing personal portable valuables having a security or restraining slot comprises a generally hook-shaped restraining member having a moveable inner flange mounted in a housing, a shank section adapted to extend into the restraining slot of the portable device, and a hook section adapted to engage an inner surface of the exterior wall of the portable device through the restraining slot. A fastener is coupled through the housing for extending into an aperture in the inner flange when the restraining member is in the locked position to thereby inhibit movement of the restraining member to the installation, or unlocked, position and prevent removal of the locking mechanism from the portable device. Adhesive-backed locking mechanisms for portable valuables lacking a security slot also are described.
