Abstract
Abstract Disclosed is a raised floor panel and panel assembly for computer and similar installations. The panels are supported above a subfloor on pedestals and are easily installed and removed for later access to the space beneath the floor. Each panel comprises a core with or without strengthening metal sheets about which is wrapped a flexible and at least partially resilient floor covering, such as carpet or flexible tile material. In one form, the floor covering extends over the edges and for a short distance beneath each panel. In another form, a sheet metal pan underlies the core and has upturned flanges in contact with the outer face of the floor covering extending over the edges of the core.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
165 words
An elevated floor assembly comprising a subfloor, a support structure spaced about said subfloor, a plurality of floor panels supported by said support structure in spaced relation above said subfloor, each panel comprising a core having top and bottom surfaces joined by at least three edges, a flexible floor covering integrally overlying said top surface and having portions overlying the edges of said core, a sheet metal plate underlying each of said cores and having upturned flanges overlying both the covering portions overlying the core edges and the edges of said core, said flanges lying in electrical contact with the outer faces of said overlying covering portions, means for electrically coupling adjacent plates, said panel having a thickness providing sufficient strength for use as flooring in said elevated floor assembly, and static electricity discharge means coupled to at least one of said adjacent sheet metal plates for discharging static electricity in the floor covering through both said discharge means and the electrically coupled adjacent plates.
Claim 2
Dependent Claim
165 words
An elevated floor assembly comprising a subfloor, a support structure spaced about said subfloor, a plurality of floor panels supported by said support structure in spaced relation above said subfloor, each panel comprising a core having top and bottom surfaces joined by at least three edges, a flexible floor covering integrally overlying said top surface and having portions overlying the edges of said core, a sheet metal plate underlying each of said cores and having upturned flanges overlying both the covering portions overlying the core edges and the edges of said core, said flanges lying in electrical contact with the outer faces of said overlying covering portions, means for electrically coupling adjacent plates, said panel having a thickness providing sufficient strength for use as flooring in said elevated floor assembly, and static electricity discharge means coupled to at least one of said adjacent sheet metal plates for discharging static electricity in the floor covering through both said discharge means and the electrically coupled adjacent plates.
Claim 3
Dependent Claim
20 words
