Abstract

Abstract A floor panel for use in elevated floor assemblies having a bottom metal sheet and a top metal sheet sandwiched on each side of a solid noncompressible core. The bottom has an upwardly turned side deflected away from the side of the core forming a first shoulder on the upper edge thereof and the top has a downwardly deflected side spaced from the first shoulder forming a second shoulder such that they are spaced, non-overlapping sides. A flexible edge member having an outer shoulder engaging the first shoulder of said bottom metal sheet and an inner channel formed longitudinally thereof to receive the downwardly deflected edge of the top metal sheet is wedged between the top metal sheet edge and the bottom metal sheet edge and is locked in by the first and second shoulder on the bottom and top sheet respectively. Further, an abuttment surface formed on the outer and inner edges adapted to abutt the inner edge of the bottom metal sheet and the side of the noncompressible core so as to limit rotation from torsional forces applied to the outer flexible edge member of the floor panel.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 231 words
A floor panel for use in elevated floor assemblies, the panel comprising: a noncompressible solid core having a side; a bottom metal sheet having an upwardly deflected edge formed about a periphery of the bottom, the edge forming a first shoulder; a top metal sheet having a downwardly deflected edge, said edge spaced from the side of said core and inwardly of said first shoulder, said edge further forming a second shoulder, and said top metal sheet and bottom metal sheet being positioned on opposed sides of said core; and a flexible edge member having an outer shoulder engaging said first shoulder on said bottom metal sheet and an inner channel formed in said flexible edge member having an upper inner shoulder engaging the upper surface of said top metal sheet and a lower inner shoulder engaging said second shoulder of said top metal sheet, the channel receiving said deflected edge of said top metal sheet to prevent rotation of the flexible edge member, said flexible edge member being wedged between the upward deflected edge of the bottom metal sheet and the downward deflected edge of the top metal sheet, and said flexible edge member further having an abuttment surface formed adjacent said channel and lower inner shoulder, the abuttment surface having a substantially flat, wide surface preventing inward rotation of the edge member to engage a side of said core.
Claim 2
Dependent Claim 231 words
A floor panel for use in elevated floor assemblies, the panel comprising: a noncompressible solid core having a side; a bottom metal sheet having an upwardly deflected edge formed about a periphery of the bottom, the edge forming a first shoulder; a top metal sheet having a downwardly deflected edge, said edge spaced from the side of said core and inwardly of said first shoulder, said edge further forming a second shoulder, and said top metal sheet and bottom metal sheet being positioned on opposed sides of said core; and a flexible edge member having an outer shoulder engaging said first shoulder on said bottom metal sheet and an inner channel formed in said flexible edge member having an upper inner shoulder engaging the upper surface of said top metal sheet and a lower inner shoulder engaging said second shoulder of said top metal sheet, the channel receiving said deflected edge of said top metal sheet to prevent rotation of the flexible edge member, said flexible edge member being wedged between the upward deflected edge of the bottom metal sheet and the downward deflected edge of the top metal sheet, and said flexible edge member further having an abuttment surface formed adjacent said channel and lower inner shoulder, the abuttment surface having a substantially flat, wide surface preventing inward rotation of the edge member to engage a side of said core.
Claim 3
Dependent Claim 30 words
A floor panel according to claim 1, including a tread material secured to the top metal sheet, the upper surfaces of said tread material and flexible edge member being coplanar.
Claim 4
Dependent Claim 51 words
A floor panel according to claim 1, including an adjustable pedestal comprising: a base having an upwardly extending treaded stud; a hollow tubular upper member having a threaded passage adapted to move over said treaded stud of said lower base; a head adapted to support a corner of said floor panel.
Claim 5
Dependent Claim 252 words
A floor panel for use in elevated floor assemblies, the panel comprising: a noncompressible solid core having a side along the periphery thereof; a bottom metal sheet having an upwardly extending edge formed about the periphery thereof, said upwardly extending edge further being deflected outwardly from the side of said core and the upper edge thereof forming a first shoulder; a top metal sheet having a downwardly extending edge, said edge spaced from said core and inwardly of said first shoulder, the outer end of said edge further forming a second shoulder, said top metal sheet and bottom metal sheet being positioned on opposed sides of said core and secured thereto by adhesive; and a flexible edge member having an outer shoulder engaging said first shoulder of said bottom metal sheet, a first abuttment surface formed adjacent said outer shoulder to engage the inner surface of the edge of said bottom metal sheet, said flexible edge member further having a continuous channel formed longitudinally thereof having an upper shoulder to engage an upper corner of said top metal sheet and a lower shoulder to engage said second shoulder on said top metal sheet, the channel receiving said deflected edge between the upper and lower shoulder to prevent upward movement of said flexible edge member, said flexible edge member further having a second abuttment surface immediately adjacent said lower shoulder of said channel having a substantially flat, wide surface engaging the side of said core to prevent inward rotation of the edge member.
Claim 6
Dependent Claim 252 words
A floor panel for use in elevated floor assemblies, the panel comprising: a noncompressible solid core having a side along the periphery thereof; a bottom metal sheet having an upwardly extending edge formed about the periphery thereof, said upwardly extending edge further being deflected outwardly from the side of said core and the upper edge thereof forming a first shoulder; a top metal sheet having a downwardly extending edge, said edge spaced from said core and inwardly of said first shoulder, the outer end of said edge further forming a second shoulder, said top metal sheet and bottom metal sheet being positioned on opposed sides of said core and secured thereto by adhesive; and a flexible edge member having an outer shoulder engaging said first shoulder of said bottom metal sheet, a first abuttment surface formed adjacent said outer shoulder to engage the inner surface of the edge of said bottom metal sheet, said flexible edge member further having a continuous channel formed longitudinally thereof having an upper shoulder to engage an upper corner of said top metal sheet and a lower shoulder to engage said second shoulder on said top metal sheet, the channel receiving said deflected edge between the upper and lower shoulder to prevent upward movement of said flexible edge member, said flexible edge member further having a second abuttment surface immediately adjacent said lower shoulder of said channel having a substantially flat, wide surface engaging the side of said core to prevent inward rotation of the edge member.
