ABSTRACT:
A fabricated case is described which is suitable for carrying relatively heavy objects. Two opposed hinged concave shells are shown, each including a back wall and four side walls. In at least one of the shells, at least three of the walls joined by integral corners are formed from a single sheet of semi-rigid material, such as plastic, bent by the use of a heated tool, and joined along an edge of the sheet to a metallic frame section which provides strength and rigidity to the case. In contrast to molded attache or luggage case shells, the shells may be made with greater depth and in diverse shapes without the use of vacuum molds or other special tooling. The preferred frame section is F-shaped in cross section with a channel portion and an integral flange portion extending therefrom and forming a continuation of the base of the channel portion. The flange portion lies against the outer side of the walls with the channel portion extending transversely across the coextensive edge. An elongated clamping member is disposed against the inner side of the walls and is secured to the frame section by suitable fasteners.
