Abstract: A truck assembly and luggage associated therewith includes a base panel, a bottom panel and side panels. The bottom panel and the side panels intersect the base panel at a mutual edge. Two wheel cavities extend through the base panel and the bottom panel and across the mutual edge to receive wheels. Axles are positionable in mounting panels to each side of each wheel cavity. The mounting panels include semicircular mounting surfaces and access passages thereto. Mounting caps include plates and extended bosses with cap surfaces forming segments of a cylinder to cooperate with the semicircular mounting surfaces to form cylindrical mountings. Axles are positioned in the cylindrical mountings and in turn rotatably mount the wheels. Reusable fasteners in the form of screws hold the plates to the base panel of the truck assembly. A slidably mounted handle associated with the luggage case is positioned to be parallel to the bottom panel and at the far side of the case from the base panel.

Abstract: A combination collapsible backpack and lined compartment includes a backpack formed of a back section, a front section any bottom section attached to the front section and back section. The backpack further includes a pair of shoulder straps attached to the back section. The backpack may be collapsed onto the bottom section of the backpack. An upper lid is attached to the backpack, and the lid attachment attaches the bottom section of the backpack and the upper lid when the backpack is collapsed onto the bottom section of the backpack, so that the collapsed backpack is between the bottom section of the backpack and the lid. A carrying compartment has side walls and a bottom wall. A compartment attachment attaches the side walls of the carrying compartment to the bottom section of the backpack so that the bottom section of the backpack forms a top section of the carrying compartment.
