Abstract: An assembly for reducing the conveyance of material on a top surface of a secondary structure movable into and out of an opening in a primary structure includes a mounting member including a first portion coupled to an upper interior surface of the opening of the primary structure and a second portion situated on an exterior of the primary structure adjacent the opening. The assembly further includes a pivotable member coupled to the second portion of the mounting member and being pivotable between an open position and a closed position corresponding to an extended position and a retracted position of the secondary structure with respect to the primary structure, and a flexible seal member coupled to the pivotable member and movable therewith such that when the secondary structure is extended the seal member engages the top surface of the secondary structure at a location offset from the opening.

Abstract: Locking mechanism assemblies are provided for retaining a slide-room of a recreational vehicle in a retracted position. An exemplary assembly has a strut member extending between the slide-room and a wall of the recreational vehicle. The strut member is pivotable between a first position and a second position corresponding to an extended position and a retracted position, respectively, of the slide-room. The assembly further includes a guide member coupled to the strut member and movable therewith such that pivoting motion of the strut member between the first position and the second position causes corresponding linear motion of the guide member along a guide between a first position and a second position. The strut member applies a compressive force to the slide-room and a vehicle wall adjacent the slide-room to inhibit movement of the slide-room when the slide-room is in the retracted position.

Abstract: The present application relates to a wall panel for recreational vehicles. In one representative embodiment, a wall panel for a recreational vehicle comprises a main body defining at least one pre-formed panel opening, and an inwardly extending peripheral flange located along a perimeter of the at least one pre-formed panel opening. The wall panel is configured to be mounted onto a structural wall of the recreational vehicle such that the peripheral flange covers an inner surface of a corresponding opening defined in the structural wall.

Abstract: A slide-room for installation in a recreational vehicle or other structure is disclosed. The slide-room comprises a shell, which can be constructed from fiberglass. The shell comprises an end wall, a ceiling, a floor, two opposing side walls, and a flange extending from the end wall, wherein the end wall, the ceiling, the floor, the side walls and the flange comprise a one-piece, unitary construction. Also disclosed are methods for molding composite components, such as slide-room. In one specific implementation, the shell for a slide-room is formed from fiberglass using a vacuum-assisted resin transfer process. During the vacuum-assisted resin transfer process, a mold apparatus can include a perimeter seal system to inhibit resin from flowing into spaces between mating components of the mold. The perimeter seal system can include clamp seal assemblies and/or vacuum seal assemblies.

Abstract: An embodiment of a method of designing a storage system begins with a step of assigning decision variables to a range of candidate storage systems. Each of the decision variables identifies a single candidate storage system. The method concludes with a step of employing the decision variables in a mathematical program to determine which of the candidate storage systems meets availability and reliability criteria and incurs a near minimal projected cost.

Abstract: A configuration method includes selecting a design configuration, and modeling the solution configuration having a failure event for the selected solution configuration to determine an amount of down time associated with the failure event. A first penalty cost function is applied the amount of down time to determine a first penalty cost associated with the failure event of the selected solution configuration.

Abstract: A device for temporarily mounting a billboard to an exterior surface on a vehicle utilizes a rectangular frame for supporting the billboard and a pair of vacuum cups for attaching the frame to the side of the vehicle. The vacuum cups are provided with a pumping mechanism for creating a substantially leak-proof seal against the surface of the vehicle and for thus preventing unintended detachment of the sign from the surface.
