A foundation unit which can be relaxed in a compact configuration for shipping and which can be then elevated to an expanded state for completion. The foundation unit includes a rectangular grid wire top bearing structure, a rigid bottom substructure, and a series of spaced, parallel intermediate rows of wire supports. The wire supports are oriented in pairs, with the bottom attachment segments of the wire supports being adjacent one another and secured to the bottom substructure. The top attachment segments of the wire supports are spaced from one another such that the wire supports of each pair form a generally V-shaped configuration. The wire supports are sandwiched between spaced longitudinal grid wires of the top bearing structure so that, prior to being secured to the bottom substructure, the wire supports are pivotally secured to the top bearing structures so that the foundation unit can be selectively relaxed for storage or shipping.

Foundation unit and method of making the same

A wire support member for a foundation unit, the resulting foundation unit, and a method of fabricating the foundation unit. The wire support member comprises a pair of parallel wire elements arranged in mirror image with a transverse link extending between and joining the wire elements. A dimple is formed in the top of each of the wire elements to form an engagement location to accommodate and seat a grid wire extending transverse to the wire support member. The foundation unit is comprised of a series of the wire support members installed in a flat grid wire top bearing structure and affixed to a rigid bottom substructure. The foundation unit is formed by inserting a wire support member at an oblique angle to the grid wire top bearing structure with the wire elements straddling a pair of longitudinal grid wires and with one wire element being located on one side of a transverse grid wire and with the other wire element being located on the other side of the transverse grid wire. The support member is then inserted and pivoted until its top is generally coextensive with the flat grid, and it is then rotated until the transverse grid wire is seated in the dimples.
