Abstract
Abstract An assembly for fastening an insulation batt to a supporting surface. The fastening assembly includes an elongated fastener which is driven into the supporting surface with the head end of the fastener protruding from the supporting surface a distance approximately equal to the thickness of the batt of insulation. The batt is then impaled upon the protruding fastener and pushed down thereon until the head of the fastener protrudes from the surface of the batt remote from the supporting surface. A planar locking clip having a keyhole-shaped opening is then slipped over the fastener head and wedged between the fastener head and the batt. The locking clip is held in place by engagement with the fastener head, and prevents the insulation batt from pulling away from the supporting surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A fastening assembly for use in blind fastening a resilient and compressible sheet-like layer of material to a supporting surface, said assembly comprising: a nail-like fastener having an elongated shank of substantially constant cross-section, a pointed end, and a radially expanded head end of predetermined diameter; and a planar clip member formed with a slot for receiving the fastener shank, said slot having a length which is greater than the diameter of said fastener head and consisting of a restricted part which opens into an elliptical part, each of said parts having a width which is less than the diameter of said fastener head but greater than the diameter of said fastener shank, said elliptical part having a width greater than the width of said restricted part and a length greater than the diameter of said fastener head.
Claim 2
Dependent Claim
138 words
A fastening assembly for use in blind fastening a resilient and compressible sheet-like layer of material to a supporting surface, said assembly comprising: a nail-like fastener having an elongated shank of substantially constant cross-section, a pointed end, and a radially expanded head end of predetermined diameter; and a planar clip member formed with a slot for receiving the fastener shank, said slot having a length which is greater than the diameter of said fastener head and consisting of a restricted part which opens into an elliptical part, each of said parts having a width which is less than the diameter of said fastener head but greater than the diameter of said fastener shank, said elliptical part having a width greater than the width of said restricted part and a length greater than the diameter of said fastener head.
Claim 3
Dependent Claim
16 words
The fastener assembly of claim 1, wherein said slot is completely contained within said clip member.
Claim 4
Dependent Claim
191 words
A fastening assembly for use in securing resiliently compressible insulation batting to a supporting surface, said assembly comprising: a nail-like fastener having an elongated shank and a radially expanded head of predetermined diameter; and a planar clip member formed with a web containing a slot for receiving the fastener shank, said slot consisting of an elliptical portion and a restricted portion communicating therewith, said elliptical portion having a length which is greater than its width, the length of the elliptical portion being greater than the diameter of the fastener head, and the width of the elliptical portion being less than the diameter of the fastener head but greater than the diameter of said fastener shank whereby said elliptical portion provides means for preventing the clip from being drawn over the fastener head so long as said web is parallel to the fastener head, said means also permitting said fastener head to be passed through said slot when said web is tilted at an angle to said fastener head, said restricted portion having a width greater than the diameter of said fastener shank but less than the width of said elliptical portion.
Claim 5
Dependent Claim
191 words
A fastening assembly for use in securing resiliently compressible insulation batting to a supporting surface, said assembly comprising: a nail-like fastener having an elongated shank and a radially expanded head of predetermined diameter; and a planar clip member formed with a web containing a slot for receiving the fastener shank, said slot consisting of an elliptical portion and a restricted portion communicating therewith, said elliptical portion having a length which is greater than its width, the length of the elliptical portion being greater than the diameter of the fastener head, and the width of the elliptical portion being less than the diameter of the fastener head but greater than the diameter of said fastener shank whereby said elliptical portion provides means for preventing the clip from being drawn over the fastener head so long as said web is parallel to the fastener head, said means also permitting said fastener head to be passed through said slot when said web is tilted at an angle to said fastener head, said restricted portion having a width greater than the diameter of said fastener shank but less than the width of said elliptical portion.
Claim 6
Dependent Claim
119 words
A fastening assembly comprising a planar batt of resiliently compressible material; a nail-like fastener having a shank of sufficient length to pass through said batt and into a supporting surface to which said batt is to be affixed, said fastener having a radially expanded head of predetermined diameter; and a clip having a planar web containing slot means operable to receive said fastener shank and to pass said fastener head when said web is tilted at an angle with respect to said fastener head, and operable to prevent passage of said fastener head when said web is parallel to said fastener head; said resiliently compressible material being operable to bias said clip into parallel contact with said fastener head.
Claim 7
Dependent Claim
119 words
A fastening assembly comprising a planar batt of resiliently compressible material; a nail-like fastener having a shank of sufficient length to pass through said batt and into a supporting surface to which said batt is to be affixed, said fastener having a radially expanded head of predetermined diameter; and a clip having a planar web containing slot means operable to receive said fastener shank and to pass said fastener head when said web is tilted at an angle with respect to said fastener head, and operable to prevent passage of said fastener head when said web is parallel to said fastener head; said resiliently compressible material being operable to bias said clip into parallel contact with said fastener head.
Claim 8
Dependent Claim
76 words
In combination with a supporting surface; a planar batt of resiliently compressible material overlying said supporting surface; a nail-like fastener piercing said batt and penetrating said supporting surface, said fastener having a radially expanded head positioned adjacent to an outer surface of said batt; and a planar clip having a slot through which said fastener extends, said clip being sandwiched between said batt and said fastener head and biased against said fastener head by said batt.
Claim 9
Dependent Claim
76 words
In combination with a supporting surface; a planar batt of resiliently compressible material overlying said supporting surface; a nail-like fastener piercing said batt and penetrating said supporting surface, said fastener having a radially expanded head positioned adjacent to an outer surface of said batt; and a planar clip having a slot through which said fastener extends, said clip being sandwiched between said batt and said fastener head and biased against said fastener head by said batt.
Claim 10
Independent Claim
145 words
A method of securing a sheet-like batt of resiliently compressible material, such as insulation, to a supporting surface, comprising the steps of: (a) driving a network of fasteners into the supporting surface in a predetermined pattern, with the fasteners protruding from the supporting surface for a distance approximately equal to the thickness of the batt; (b) impaling the batt on the fastener network to an extent wherein fastener heads protrude through the outermost surface of the batt; (c) compressing the batt in areas around the protruding fastener heads to allow planar clip members to be mounted on the fasteners between the batt and the fastener heads; (d) positioning planar clip members about the fastener shanks between the fastener heads and the batt; and, (e) releasing the batt from compression to enable the batt to rebound sufficiently to bias the clip members against the fastener heads.
