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. The floor covering extends over the edges and for a short distance beneath each panel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
An elevated floor assembly comprising a subfloor, a plurality of pedestals spaced about said subfloor, and a plurality of floor panels supported by said pedestals in spaced relation above said subfloor, each panel comprising a rectangular core having top and bottom surfaces joined by four edges, a flexible and at least partially resilient floor carpet integrally overlying said tip surface and said edges of said core, portions of said carpet on adjacent panels overlying said edges being in abutting contact with each other, said carpet also extending integrally along said bottom surface of each of said cores adjacent each of said edges, said panel having a thickness on the order of 1 to 2 inches with sufficient strength for use as a flooring in said elevated floor assembly, and static electricity discharge means engaging the portions of said carpet extending along the bottom surface of the core of at least some of said panels whereby static electricity in the carpet of said panels may be discharged through both said discharge mans and the abutting carpet surface of adjacent panels.
