Abstract: The individual structural member of the invention includes a pair of parallel panels which are spaced from each other to define a cavity therebetween. The panels are staggered in the longitudinal direction so that an end section of one panel extends beyond an end of the other panel and vice versa to form a front extension section and a rear extension section of the structural member. The non-extension end edge of each panel is connected to the opposing panel by a flat wall which is normal to the plane of both panels. Each extension section is provided with a flange. The front section flange of one structural member is adapted to interlock with the rear section flange of another structural member so that the structural members can be assembled in end to end fashion with the panels of one structural member being coplanar with the panels of adjoining structural members to form a double wall of, for example, a container.

Abstract: The disclosure relates to a system of storage components which can be converted to a desk. A storage member of orthogonal configuration has a top portion releasably secured to a bottom portion. Separable fastener enable the top portion to be removed and reattached to the bottom portion to form a desk. Additional support is provided to support the portion of the desk distal to the interface of the top and bottom portion where attached by the separable fastener. The fastener is integrated with the various portions of the storage components to provide a relatively unobtrusive surface for the desk when erected and for transport as well.

Abstract: The disclosure relates to a system for stacking cases in a nesting relationship. A number of cases, each substantially identical to the other are configured to permit stacking in a nested relationship in a number of directions. Each such case includes corner brackets with recesses and protrusions which interact with complementary brackets on adjacent cases. Corner brackets in cooperation with other edge brackets also permit stacking in a nested relationship when the covers for these cases are removed and the orientation of the cases is shifted. A latching means is also provided to secure the cover in place without adversely affecting the latching mechanism.
