Abstract: Of the various carrying cases especially designed to isolate the contained laptop computer from impact forces, all are deficient in isolating the laptop computer from impacts from all directions, for example if the case containing the laptop computer were dropped on any side, edge or corner. The disclosed case provides a lightweight framed shock-absorbing insert to resist the impact and to channel much of the impact energy away from the laptop computer. This insert has two flat panels sandwiching the laptop computer. These panels flex in response to impact from any direction, while isolating the laptop computer from direct impact with the floor or the like during impact of the case with the floor. The panels are constrained from collapsing by bending out of the plane of the panel during most impacts. Constraining structures include a surounding frame between the outer edges flat panels, and surrounding textile constructions that cooperate to keep the flat panels parallel and generally flat during impacts.

Abstract: A wheeled upright luggage case is disclosed. The best embodiment of the case has wheels to allow the case to stand upright in a stable and balanced position without attendance by the user. The case has a wheel handle to allow the user to push or pull the case across a supporting surface. The case may be pushed or pulled on either four wheels or two wheels. When four wheels are used, the full weight of the case and its contents are borne by the wheels, relieving the user from having to bear with her arm any of the weight of the luggage. The body of the case is designed to have a specific range of tilt angles from the vertical; by tilting the body of the case toward the user, the design of the case improves the stability of the case while it is pushed across a supporting surface on four wheels. Various case body configurations and push handle arrangements are disclosed.

Abstract: Pick-up trucks are very popular vehicles. The versatility provided by the truck bed in the pick-up truck is aided by providing a truck box usually a monolithic elongated container fastened to the truck bed that usually spans the width of the truck bed. Each end of this type of truck box is support by laterally flanking walls of the truck bed. However, once installed, these boxes occupy a considerable space and usually must be removed so that large items can be carried in the truck bed. The disclosed collapsible truck box provides the functionality of a fixed sized truck box but can be easily collapsed by the user to occupy a very small portion of the truck bed space. Hinged connections between the lid wall, back wall, front wall and bottom wall provide this collapsing and erecting function. Preferably side walls at each end of the truck box, with each wall including its own vertically oriented hinge, further enhance the functionality of the disclosed box.
