Abstract
Abstract The system includes a flexible button top which has a sleeve appurtenance which is force-fitted over an externally helically grooved stud assembly having an integral self-adhesive back mounting plate. The button top is flexible enough so that it can be applied to, and removed from the stud assembly without the use of a tool, yet it is hard enough so that the stud will not perforate the flexible button top when impacted. The adhesive-backed stud assembly includes a helically threaded metallic screw perpendicularly attached to a metallic circular disc with a plastic foam backing impregnated with adhesive. The adhesive backing is covered by a release film prior to use. The adhesive-backed stud assembly can be applied without the use of a tool.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
In apparatus for applying sheet-like material to areas of a vehicle surrounded by walls including a plurality of externally grooved stud assemblies secured at spaced locations to said wall and projecting inwardly thereof to provide a non-pointed distal end; a layer of said material covering the interior of said walls, said assemblies projecting at least partially through said material; and a button for each assembly, including a head and sleeve for fitting over an associated stud assembly and being held by the grooves thereof, the improvement wherein said stud assemblies comprise a flat, thin base, a grooved stud attached to said base and extending perpendicular to a front face of said base, a layer of flexible foam material on the back side of said base; pressure-sensitive adhesive coating on the exterior side of said foam material; and a release film covering said adhesive.
Claim 2
Dependent Claim
143 words
In apparatus for applying sheet-like material to areas of a vehicle surrounded by walls including a plurality of externally grooved stud assemblies secured at spaced locations to said wall and projecting inwardly thereof to provide a non-pointed distal end; a layer of said material covering the interior of said walls, said assemblies projecting at least partially through said material; and a button for each assembly, including a head and sleeve for fitting over an associated stud assembly and being held by the grooves thereof, the improvement wherein said stud assemblies comprise a flat, thin base, a grooved stud attached to said base and extending perpendicular to a front face of said base, a layer of flexible foam material on the back side of said base; pressure-sensitive adhesive coating on the exterior side of said foam material; and a release film covering said adhesive.
Claim 3
Dependent Claim
42 words
Apparatus as set forth in claim 1, wherein for each of said stud assemblies, said base comprises a disc-shaped plate with a conical offset formed in the center thereof truncated by an aperture in which said grooved screw is received and secured.
Claim 4
Dependent Claim
32 words
Apparatus as set forth in claim 1, wherein the application area of said assemblies comprising the adhesive-coated portion of said foam material is in the range of 3 to 6.25 square inches.
Claim 5
Dependent Claim
14 words
The apparatus of claim 2 wherein said foam material is impregnated with said adhesive.
Claim 6
Dependent Claim
109 words
Apparatus as set forth in claim 2 wherein said buttons are formed from a material soft enough to permit force-fitting of said sleeve over an associated screw without turning, said button material being of a hardness and cooperating with the thickness of said sleeve and said head to prevent perforation of the body of said button by said stud upon impact, prior to the yielding of said stud under said impact; and said stud is so designed that upon impact said screw or said cone configuration or the attachment to the screw yields by bending or breaking before any poriton of the stud perforates the body of the button.
Claim 7
Dependent Claim
34 words
Apparatus as set forth in claim 5, wherein said sheet-like material is selected from the class of materials having at least one of the properties of sound-proofing, thermal insulating, vibration absorbing, and decorative trim.
Claim 8
Dependent Claim
34 words
Apparatus as set forth in claim 1, wherein said sheet-like material is selected from the class of materials having at least one of the properties of sound-proofing, thermal insulating, vibration absorbing, and decorative trim.
