Abstract
Abstract An elevated floor has two separate types of floor panels arranged in alternating order on adjustable support legs. Base floor panels and access floor panels are formed from squares of low density oriented strand material having extruded metal cladding strips along the peripheral edges of the squares. The base floor panels include edge cladding strips having a support flange extending outwardly from the base panel peripheral edge. The access panels include a different type of cladding strip designed to seat on the support flange of the base panel cladding strip. Detachable riser beams are provided for assembly of multilevel stepped raised floors.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
92 words
An elevated floor assembly comprising: a plurality of base panels each having an upper surface, a lower surface and a peripheral edge each of said base panels including a base panel cladding strip received along said base panel edges, said base panel cladding strips each having a generally upright web extending approximately the thickness of said base panel edge, and a generally horizontal access panel engaging flange extending laterally and outwardly from said web; a plurality of access panels each having an upper surface, a lower surface and a peripheral edge; and
Claim 2
Dependent Claim
92 words
An elevated floor assembly comprising: a plurality of base panels each having an upper surface, a lower surface and a peripheral edge each of said base panels including a base panel cladding strip received along said base panel edges, said base panel cladding strips each having a generally upright web extending approximately the thickness of said base panel edge, and a generally horizontal access panel engaging flange extending laterally and outwardly from said web; a plurality of access panels each having an upper surface, a lower surface and a peripheral edge; and
Claim 3
Dependent Claim
46 words
a plurality of support legs detachably coupled to said base panels, said base panels and said access panels being positioned in alternating juxtaposition whereby said base panels are supported by said support legs and said access panels are supported by said base panel cladding strip flanges.
Claim 4
Dependent Claim
46 words
a plurality of support legs detachably coupled to said base panels, said base panels and said access panels being positioned in alternating juxtaposition whereby said base panels are supported by said support legs and said access panels are supported by said base panel cladding strip flanges.
Claim 5
Dependent Claim
46 words
The invention as claimed in claim 1, said base panel cladding strips each extending along the length of its respective base panel peripheral edge and including upper and lower, generally horizontal base panel engaging flanges for engaging the upper and lower surfaces of said base panel.
Claim 6
Dependent Claim
52 words
The invention as claimed in claim 2, said lower base panel engaging flanges and said access panel engaging flanges each having end portions engageable with said support legs whereby said base panel cladding strips are supported by said support legs and said base panels are supported by said base panel cladding strips.
Claim 7
Dependent Claim
38 words
The invention as claimed in claim 3, said support legs each including a generally vertical support rod and an uppermost, generally horizontal base panel supporting plate, said supporting plate engageable with said base panel cladding strip end portions.
Claim 8
Dependent Claim
43 words
The invention as claimed in claim 4, said generally vertical support rod comprising first and second telescoping members and means for adjusting the height of said support rod by shifting the position of said first and second telescoping members relative to each other.
Claim 9
Dependent Claim
49 words
The invention as claimed in claim 4, said support legs each including a lowermost ground engaging plate and means for adjustably coupling said ground engaging plate to said vertical support rod whereby the angular tilt of said ground engaging plate is selectively alterable relative to said vertical support rod.
Claim 10
Dependent Claim
37 words
The invention as claimed in claim 1 including an access panel cladding strip received along said access panel edges, each access panel cladding strip having a generally upright web extending approximately the thickness of said access panel.
Claim 11
Dependent Claim
46 words
The invention as claimed in claim 7, said access panel cladding strips each extending along the length of its respective access panel peripheral edge and including upper and lower, generally horizontal access panel engaging flanges for engaging the upper and lower surfaces of said access panel.
Claim 12
Dependent Claim
38 words
The invention as claimed in claim 8, said access panel generally upright web being canted slightly inwardly towards the center of said access panel from said upper access panel engaging flange towards said lower access panel engaging flange.
Claim 13
Dependent Claim
35 words
The invention as claimed in claim 1, including a plurality of fixed length subfloor legs detachably coupled to certain of said adjustable support legs whereby said elevated floor assembly includes a plurality of stepped levels.
Claim 14
Dependent Claim
23 words
The invention as claimed in claim 10, including a generally vertical enclosure panel for spacing the gap between said plurality of stepped levels.
