Patent ID: 8295035

Claim:
A multiple component, multilevel floor construction for distribution of conditioned air to equipment on an access floor supported over a base floor, said multilevel floor construction comprising: a modular array of unitary modules, each module including an assembly of support struts, each strut of each module extending upwardly from a base floor support element to a top access floor panel support end, each module further including an intermediate conductor support floor panel supported by and substantially sealed to the assembly of struts intermediate the base support element and the top access panel support end of the assembly of struts, selected intermediate conductor support floor panels including a substantially centrally located through passage; access floor panels seated respectively on said top panel support ends of selected modules to form said access floor, whereby said modules and access floor panels form said access floor and an intermediate conductor support floor spaced from and beneath the access floor by said struts, said intermediate conductor support floor positioned above said base floor by said struts, said access floor and said intermediate conductor support floor having a substantially coextensive perimeter; perimeter closure members extending intermediate the access floor and the conductor support floor along at least a portion of the access floor and conductor floor perimeters whereby a conditioned air plenum is formed between the conductor support floor and the base floor generally sealingly separated from a service space between the access floor and the conductor support floor; and an air duct extending from a through passage of said conductor support floor panel to the access floor whereby conditioned air from said plenum is directed by said duct without dispersion into said service space; said access floor panels and intermediate conductor support floor panels of selected modules being substantially equally sized and aligned coextensively by said struts, and wherein said struts extend upwardly from said base support through said intermediate conductor support floor panels for connection to a corner of a said access floor panel by the top panel support ends; a locking mechanism located on the periphery of selected intermediate conductor support floor panels for retaining selected said conductor intermediate support floor panels joined together; a locking element for connecting at least one of the top panel support ends of said struts of said selected modules; wherein said locking element supports selected access floor panels of selected adjacent modules and; wherein said support struts of a said module extend from said foot obliquely at an angle from a center axis of said module.
