Abstract
Abstract A false floor assembly of square panels is supported on pedestals above a foundation. The panel corners rest on the pedestals and the adjacent sides of neighboring panels between pedestals are secured together by releasable ties that pass through the sides of each neighboring panel. The area below the panels is accessible by simply removing the ties and lifting one or more panels from the assembly. Loads applied to any one panel in the assembled floor are resisted by neighboring panels and the floor remains substantially flat without uneven deflections.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
An elevated false floor assembly of panels having a level and even tread surface, comprising a plurality of panels arranged side-by-side in rows and supported on pedestals at their corners, the sides of adjacent panels substantially abutting one another and being interconnected by releaseable tie means located intermediate the corners thereof, said panels each being load bearing and comprising upper and lower spaced apart metal sheets, at least one tie securing the spaced apart upper and lower sheets of each panel to the corresponding upper and lower sheets respectively, of an adjacent panel adjacent each abutting side thereof, the horizontal and vertical movements of any one panel being resisted and shared by said upper and lower sheets of adjacent panels, said tie extending generally vertically for substantially the entire panel thickness between said spaced apart upper and lower sheets of that panel, said tie being removable from above the tread surface.
Claim 2
Dependent Claim
151 words
An elevated false floor assembly of panels having a level and even tread surface, comprising a plurality of panels arranged side-by-side in rows and supported on pedestals at their corners, the sides of adjacent panels substantially abutting one another and being interconnected by releaseable tie means located intermediate the corners thereof, said panels each being load bearing and comprising upper and lower spaced apart metal sheets, at least one tie securing the spaced apart upper and lower sheets of each panel to the corresponding upper and lower sheets respectively, of an adjacent panel adjacent each abutting side thereof, the horizontal and vertical movements of any one panel being resisted and shared by said upper and lower sheets of adjacent panels, said tie extending generally vertically for substantially the entire panel thickness between said spaced apart upper and lower sheets of that panel, said tie being removable from above the tread surface.
Claim 3
Dependent Claim
22 words
The floor assembly of claim 1, wherein said tie is accessible and turnable at the upper metal sheet surfaces of adjacent panels.
Claim 4
Dependent Claim
33 words
The floor assembly of claim 1, wherein said tie is a threaded bolt and nut that directly bears on the upper sheet of one panel and the lower sheet of an adjacent panel.
Claim 5
Dependent Claim
39 words
The assembly of claim 3, wherein there are two sets of dissimilar panels arranged in checkerboard relationship, the panels of a first set having upper sheet edges that overlie and capture adjacent upper sheet rims of a second set.
Claim 6
Dependent Claim
21 words
The assembly of chain 4, wherein lower sheet flanges of said second set underlie lower sheet peripheries of said first set.
Claim 7
Dependent Claim
21 words
The assembly of chain 4, wherein lower sheet flanges of said second set underlie lower sheet peripheries of said first set.
Claim 8
Dependent Claim
20 words
The assembly of claim 5, wherein a bolt passes through the panels of said first set adjacent each side thereof.
Claim 9
Dependent Claim
18 words
The assembly of claim 6, wherein said bolt engages a captured nut secured to each of said peripheries.
Claim 10
Dependent Claim
18 words
The assembly of claim 4, wherein the corners of the panels are truncated and rest on said pedestals.
Claim 11
Dependent Claim
39 words
The floor assembly of claim 1, wherein said tie is a turnable plug and each side of each panel has a perimeter with a recess, the recesses of adjacent panel sides having sockets in register to receive said plug.
Claim 12
Dependent Claim
38 words
The floor assembly of claim 9, wherein said plug has a lower lug that bears on the lower surfaces of adjacent panel sockets and an upper circular top portion that bears on the upper surfaces of said sockets.
