Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
286 words
A one piece resilient fastener for retaining an edge portion of a sheet adjacent a panel comprising a body portion having an opening formed therethrough, an elongated flange extending outwardly from one side of said body portion adjacent one end of said opening and substantially normal to said opening and spaced from one end of said body, an elongated cover portion hinged at the opposite side of said body portion from said flange side and movable to a position overlying said flange and said body end portion, an opening formed in said cover portion in alignment with said opening in said body portion positioned overlying said flange and said body portion, means disposed on said body portion for locking said cover portion in a position overlying said flange and body portion, means for connecting said fastener to said panel comprising an elongated boss extending from said body portion and in which the opposite end of said opening from said body is formed contiguous the opening in said body, said boss having a shoulder formed thereon spaced from the end of said boss, said shoulder being of a greater width than either end of said elongated boss, and a slot extending the length of said boss from the outer surface of said boss into said opening, whereby said shoulder is flexed to provide a lesser width when said boss is introduced into an opening in said panel and returns to its initial width dimension after passing through the panel opening to initially retain said fastener on said panel, and said cover portion opening and said body portion opening through said boss are aligned with the cover in the closed position for insertion of a male fastener therein.

A one piece resilient fastener for retaining an edge portion of a sheet adjacent a panel comprising a body portion having an opening formed therethrough, an elongated flange extending outwardly from one side of said body portion adjacent one end of said opening and substantially normal to said opening and spaced from one end of said body, an elongated cover portion hinged at the opposite side of said body portion from said flange side and movable to a position overlying said flange and said body end portion, an opening formed in said cover portion in alignment with said opening in said body portion positioned overlying said flange and said body portion, means disposed on said body portion for locking said cover portion in a position overlying said flange and body portion, means for connecting said fastener to said panel comprising an elongated boss extending from said body portion and in which the opposite end of said opening from said body is formed contiguous the opening in said body, said boss having a shoulder formed thereon spaced from the end of said boss, said shoulder being of a greater width than either end of said elongated boss, and a slot extending the length of said boss from the outer surface of said boss into said opening, whereby said shoulder is flexed to provide a lesser width when said boss is introduced into an opening in said panel and returns to its initial width dimension after passing through the panel opening to initially retain said fastener on said panel, and said cover portion opening and said body portion opening through said boss are aligned with the cover in the closed position for insertion of a male fastener therein.
Claim 3
Dependent Claim
29 words
The fastener of claim 1, wherein said flange and said cover portion are each provided with a plurality of opposed teeth with said cover portion positioned overlying said flange.
Claim 4
Dependent Claim
129 words
The fastener of claim 2 wherein said locking means comprises a resilient finger disposed on said body portion and extending from adjacent said flange toward said cover portion in a positon overlying said flange, said finger having a shoulder formed near the end thereof, and an opening formed in said cover portion for receiving said finger therethrough when positioned overlying said flange, said opening being formed by said cover portion to form a lip adjacent thereto in alignment with and opposed to said shoulder finger extending into said opening, whereby said finger is caused to flex when introduced into said cover portion opening and remains in the flexed state until said shoulder is moved past said lip to thereby retain said flange and said cover portion in locking engagement.
Claim 5
Dependent Claim
131 words
The fastener of claim 1, wherein said locking means comprises a resilient finger disposed on said body portion and extending from adjacent said flange toward said cover portion in a position overlying said flange, said finger having a shoulder formed near the end thereof, and an opening formed in said cover portion for receiving said finger therethrough when positioned overlying said flange, said opening being formed by said cover portion to form a lip adjacent thereto in alignment with and opposed to said shoulder with said finger extending into said opening, whereby said finger is caused to flex when introduced into said cover portion opening and remains in the flexed state until said shoulder is moved past said lip to thereby retain said flange and said cover portion in locking engagement.
Claim 6
Dependent Claim
12 words
