Abstract
Abstract A molded fibrous surfacing system including tiles or panels and supporting means, and a method of producing the same wherein a mass of fibrous material, such as glass fibers, impregnated with a binder is compressed and shaped during compression to produce edge configurations enabling the respective panels of being supported in alignment from a main support surface.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
121 words
A surfacing panel comprising a compressed body of fibers and a binder for maintaining said body in a compressed condition, said body having a substantially planar central section surrounded by edge regions depending substantially normally therefrom of a greater density than the central section, whereby the substantially planar central section is surrounded by edge regions embodying structural rigidity; and at least one pair of the edge regions is provided with terminal portions which are formed to extend outwardly of the central section and downwardly in substantially parallel relation to the outer portion of said edge regions whereby said one pair of the edge regions are of hooklike cross-sectional configuration, said hooklike portions being adapted to engage with adjacent panels when assembled.
Claim 2
Dependent Claim
121 words
A surfacing panel comprising a compressed body of fibers and a binder for maintaining said body in a compressed condition, said body having a substantially planar central section surrounded by edge regions depending substantially normally therefrom of a greater density than the central section, whereby the substantially planar central section is surrounded by edge regions embodying structural rigidity; and at least one pair of the edge regions is provided with terminal portions which are formed to extend outwardly of the central section and downwardly in substantially parallel relation to the outer portion of said edge regions whereby said one pair of the edge regions are of hooklike cross-sectional configuration, said hooklike portions being adapted to engage with adjacent panels when assembled.
Claim 3
Dependent Claim
31 words
A surfacing panel as defined in claim 1 including a film of flexible sheet material affixed to the obverse surface of the central section and the edge regions of said body.
Claim 4
Dependent Claim
17 words
A surfacing panel as defined in claim 2 wherein said film of flexible sheet material is resinous.
Claim 5
Dependent Claim
108 words
A supported panel system comprising in combination: a plurality of panels arranged in planar array, each of said panels including a compressed body of fibers and a binder for maintaining said body in a compressed condition, said body having a substantially planar central section surrounded by depending edge regions compressed to a greater degree than the central section; and a plurality of structural support elements arranged to cooperatively support said panels, said elements including suspension means for supporting the edge regions of adjacent panels in parallel alignment, said support elements having spaced apart depending members engaging opposed surfaces of abutting edge regions of adjacent ones of said panels.
Claim 6
Dependent Claim
108 words
A supported panel system comprising in combination: a plurality of panels arranged in planar array, each of said panels including a compressed body of fibers and a binder for maintaining said body in a compressed condition, said body having a substantially planar central section surrounded by depending edge regions compressed to a greater degree than the central section; and a plurality of structural support elements arranged to cooperatively support said panels, said elements including suspension means for supporting the edge regions of adjacent panels in parallel alignment, said support elements having spaced apart depending members engaging opposed surfaces of abutting edge regions of adjacent ones of said panels.
Claim 7
Dependent Claim
15 words
A supported panel system as defined in claim 4 wherein the fibers are mineral fibers.
Claim 8
Dependent Claim
15 words
A supported panel system as defined in claim 4 wherein the fibers are glass fibers.
Claim 9
Dependent Claim
36 words
A supported panel system as defined in claim 4 wherein the portions of said body joining the central section and the edge regions of said body are compressed to a higher density than the central section.
Claim 10
Dependent Claim
32 words
A supported panel system as defined in claim 4 including a film of flexible sheet material affixed to the obverse surface of the central section and the edge regions of said body.
Claim 11
Dependent Claim
18 words
A supported panel system as defined in claim 8 wherein said film of flexible sheet material is resinous.
Claim 12
Dependent Claim
69 words
The invention defined in claIm 4 wherein at least one pair of the edge regions is provided with terminal portions which are formed to extend outwardly of the central section and downwardly in substantially parallel relation to the outer portion of said edge regions whereby said one pair of the edge regions are of hooklike cross-sectional configuration, said hooklike portions being adapted to engage with adjacent panels when assembled.
Claim 13
Dependent Claim
33 words
The invention defined in claim 10 wherein said support elements consist of laterally and upwardly extending flanges fitting in supporting relation with the hooklike terminal edges of the edge regions of said panels.
Claim 14
Dependent Claim
47 words
The invention defined in claim 4 wherein said support elements include a plurality of overhead supporting rails arranged in a gridlike manner having clip means depending therefrom, said clip means including extending spaced arms for frictionally receiving and supporting edge regions of adjacent ones of said panels.
Claim 15
Dependent Claim
35 words
The invention defined in claim 12 wherein the spaced arms of said clips have inwardly extending prongs to engage the edge regions of said panels and militate against the removal thereof subsequent to insertion therein.
