Abstract
Abstract A floor panel for use in elevated floor assemblies, having a unique flexible edge construction including a relatively thin, flexible strip extending around the entire perimeter of the panel and projecting laterally outwardly from contiguous side and end faces of the panel. Plural panels supported on spaced pedestals are disposed in side-by-side relation with adjacent side and end faces spaced from each other but with adjacent flexible strips in edge-overlapped relation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A floor panel for use in elevated floor assemblies, comprising: generally rectangular upper and lower facing sheets laminated to opposite faces of a relatively incompressible core; said panel having an upper face and a lower face and contiguous side and end faces; a relatively thin, flexible strip extending along said side and end faces around the perimeter of said panel, said flexible strip projecting laterally outwardly from and generally parallel with said upper face of said panel; said upper and lower facing sheets including perimeter flanges extending inwardly toward but outboard of said incompressible core; perimeter frame members surrounding said core and receiving said flanges; and said flexible strip being provided in plural strips, one carried by each of said frame members and extending substantially the entire length thereof.
Claim 2
Dependent Claim
129 words
A floor panel for use in elevated floor assemblies, comprising: generally rectangular upper and lower facing sheets laminated to opposite faces of a relatively incompressible core; said panel having an upper face and a lower face and contiguous side and end faces; a relatively thin, flexible strip extending along said side and end faces around the perimeter of said panel, said flexible strip projecting laterally outwardly from and generally parallel with said upper face of said panel; said upper and lower facing sheets including perimeter flanges extending inwardly toward but outboard of said incompressible core; perimeter frame members surrounding said core and receiving said flanges; and said flexible strip being provided in plural strips, one carried by each of said frame members and extending substantially the entire length thereof.
Claim 3
Dependent Claim
30 words
The floor panel as defined in claim 1 wherein said flexible strip includes an inboard strip portion, and said panel presents a perimeter recess captively retaining said inboard strip portion.
Claim 4
Dependent Claim
42 words
The floor panel as defined in claim 2 wherein said recess is parallel with said side and end faces; and wherein said inboard strip portion extends above the upper face of the upper facing sheet and serves as a decorative cover stop.
Claim 5
Dependent Claim
38 words
The floor panel as defined in claim 2 wherein said recess is normal to said side and end faces; and wherein said flexible strip and said inboard strip portion are disposed below said upper face of said panel.
Claim 6
Dependent Claim
35 words
The floor panel as defined in claim 2 wherein said flexible strip and said inboard strip portion comprise a single piece of dual-durometer plastic material, said inboard strip portion being formed from rigid plastic material.
Claim 7
Dependent Claim
40 words
The floor panel as defined in claim 1 including a rigid carrier member connected to said side and end faces and having a lengthwise groove; and said flexible strip presents an inboard strip portion captively retained in said lengthwise groove.
Claim 8
Dependent Claim
21 words
The floor panel as defined in claim 6 wherein said panel member presents a perimeter recess captively retaining said carrier member.
Claim 9
Dependent Claim
48 words
The floor panel as defined in claim 9 wherein each said inboard strip portion extends above the upper face of the upper facing sheet and has an inboard face spaced from and generally normal to the upper facing sheet, the inboard faces serving as a decorative cover stop.
Claim 10
Dependent Claim
40 words
The floor panel as defined in claim 8 wherein each of said perimeter frame members presents an upwardly opening perimeter recess, and wherein each of said flexible strips includes an inboard strip portion captively retained by one said perimeter recess.
Claim 11
Dependent Claim
33 words
The floor panel as defined in claim 9 wherein said flanges of the upper and lower facing sheets include embossments which promote frictional engagement of said flanges in said upper and lower grooves.
Claim 12
Dependent Claim
44 words
The floor panel as defined in claim 1 wherein each of said frame members presents a laterally outwardly opening recess; and wherein the flexible strip and the associated inboard strip portion reside below the level of the upper face of the upper facing sheet.
Claim 13
Dependent Claim
66 words
The floor panel as defined in claim 1 wherein each of said frame members comprises: a central wall positioned outboard of said flanges; an inboard frame portion cooperating with said central wall to define upper and lower grooves captively receiving said flanges; and an outboard frame portion cooperating with said central wall to define a perimeter recess captively retaining a segment of the associated flexible strip.
