Patent ID: 7454869

Claim:
A support system having multiple floors of a sub-work surface utility line containment system comprising: a) a plurality of pedestal assemblies; b) a plurality of base floor pads for placing and securing said pedestal assemblies, each pedestal assembly connecting at least two base floor pads; c) a locking assembly for securing each pedestal assembly to at least two of said base floor pads when said pedestal assemblies are positioned about said base floor pads, said locking assembly comprising: i) a plurality of projections extending from each pedestal assembly; ii) a receiving aperture forming a first discontinuous opening located in each of said base floor pads for receiving said projections in a first position, the first discontinuous opening being formed from first and second arc; and iii) a locking aperture forming a second discontinuous opening in communication with said receiving aperture for locking said pedestals when in a second position to said base floor pad, said second discontinuous opening being formed from said first arc of said first discontinuous opening and a third arc, the third arc being smaller than said second arc such that the locking aperture comprises a smaller opening than said receiving aperture, inserting said projections into said receiving apertures and rotating said pedestal assemblies from said first position to a second position rotates said corresponding projections into said locking apertures thereby securing said pedestals to said base floor pads; d) each of the pedestals includes a cap defining a work floor support surface for support of work floor panels; e) whereby rotating each of said pedestal assemblies from said first position to a second position in attaching at least two base floor pads forms a jig for self-aligning respective pedestal assemblies for supporting said work floor panels by said pedestal assemblies.
