Abstract
Abstract A self-gripping fastening device for connecting together a pair of articles, only one of which is required to be provided with the device, comprises a plurality of hooked fastening elements made of metal wire or coated metal wire, each being secured to one of the articles. Each of the elements has at least one elongated shank terminating at its free end in a hook, and bent at its other end to provide an enlarged portion which anchors the element in the article to which it is secured by penetration of the shank through the surface. When the fastening device on the one article is pressed against the opposing surface of the other article, the free ends of the fastening elements penetrate and lodge in the other article to thereby effect adhesion between the pair of articles.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
170 words
A self-gripping fastening assembly for coNnecting together a pair of articles, said fastening assembly comprising a plurality of fastening elements secured to one of said articles, each of said fastening elements comprising an elongated straight stem upstanding substantially perpendicularly from the upper surface of said article and having a hook formed at the free end thereof with said hook curving toward said upper surface and having a penetrating profile, said stem passing through said article and being bent at its end opposite said free end to form an anchoring portion extending laterally from said stem, said anchoring portion including a loop having at least a portion underlying the lower surface of said article for preventing said stem from being pulled out of said article, whereby when said upper surface of said one article is pressed against the other of said articles, the penetrating profiles at the free ends of said elongated stems penetrate said other article and lodge the hooks therein, to thereby effect adhesion between said pair of articles.
Claim 2
Dependent Claim
170 words
A self-gripping fastening assembly for coNnecting together a pair of articles, said fastening assembly comprising a plurality of fastening elements secured to one of said articles, each of said fastening elements comprising an elongated straight stem upstanding substantially perpendicularly from the upper surface of said article and having a hook formed at the free end thereof with said hook curving toward said upper surface and having a penetrating profile, said stem passing through said article and being bent at its end opposite said free end to form an anchoring portion extending laterally from said stem, said anchoring portion including a loop having at least a portion underlying the lower surface of said article for preventing said stem from being pulled out of said article, whereby when said upper surface of said one article is pressed against the other of said articles, the penetrating profiles at the free ends of said elongated stems penetrate said other article and lodge the hooks therein, to thereby effect adhesion between said pair of articles.
Claim 3
Dependent Claim
22 words
A self-gripping fastening assembly according to claim 1, wherein said fastening element is formed from metal wire of a substantially uniform diameter.
Claim 4
Dependent Claim
19 words
A self-gripping fastening assembly according to claim 1 in which said fastening element is formed from coated metal wire.
Claim 5
Dependent Claim
51 words
A self-gripping fastening assembly according to claim 1 wherein each of said fastening elements comprises a pair of spaced stems extending from said upper surface of said article, each of said stems having a hook formed at the free end thereof, and wherein said loop joins said pair of spaced stems.
Claim 6
Dependent Claim
46 words
A self-gripping fastening assembly according to claim 4 wherein said anchoring portion is formed as a closed loop disposed on the lower surface of said one article, said loop being in a plane parallel to said lower surface and being in flush engagement with the latter.
Claim 7
Dependent Claim
99 words
A self-gripping fastening assembly as according to claim 4 wherein said second article is a fabric-like material having fibers or strands, said pair of stems being inclined to approach one another at greater distances from said one article, said hooks on said stems being separated by a gap which is smaller than the diameter of said fibers or strands, said stems being adapted to momentarily flex as one or more fibers or strands are forced through said gap, whereby said fibers or strands are captured between said pair of stems by the hooks on the ends of said stems.
Claim 8
Dependent Claim
39 words
A self-gripping fastening assembly according to claim 1 in which said anchoring portion comprises a length of wire bent upon itself to provide an enlarged body of substantially larger transverse dimension than the elongated stem of said fastening element.
Claim 9
Dependent Claim
23 words
A self-gripping fastening assembly according to claim 7 in which said anchoring portion is in the form of a knot including said loop.
Claim 10
Dependent Claim
57 words
A self-gripping fastening assembly according to claim 7 in which each of said fastening elements comprises a single elongated stem extending through said one article and terminating in a hook at its free end, the enlarged body of said anchoring portion underlying said opposite surface of said body, said fastening elements being rotatable in said one article.
Claim 11
Dependent Claim
42 words
A self-gripping fastening assembly according to claim 1 wherein said anchoring portion is defined by a closed loop having sections thereof extending on opposite sides of said one article, whereby a portion of said one article is included within the closed loop.
Claim 12
Dependent Claim
48 words
A self-gripping fastening assembly as defined in claim 10 wherein each of said fastening elements also includes a second stem extending from the loop of said anchoring portion and projecting from said lower surface of said one article, said second stem having a hook at its free end.
Claim 13
Dependent Claim
73 words
A self-gripping fastening assembly according to claim 7 in which each of said fastening elements comprises a single elongated stem extending through said one article and terminating in a hook at its free end, the enlarged body of said anchoring portion underlying said opposite surface of said body, said anchoring portion also including an elongated member underlying said opposite surface and extending through and connecting the anchoring portion bodies of selected fastening elements.
Claim 14
Dependent Claim
97 words
A self-gripping fastening assembly for connecting together a pair of objects comprising a sheet-like body, a plurality of self-gripping fastening elements secured to said body, each of said fastening elements including a pair of elongated stems extending respectively from opposite surfaces of said body, each of said stems having exposed hook means thereon, whereby when said body is disposed between said pair of objects and the latter are pressed together, the stems will penetrate and lodge in said objects to thereby cause said hook means to effect adhesion and join said pair of objects to one another.
Claim 15
Dependent Claim
97 words
A self-gripping fastening assembly for connecting together a pair of objects comprising a sheet-like body, a plurality of self-gripping fastening elements secured to said body, each of said fastening elements including a pair of elongated stems extending respectively from opposite surfaces of said body, each of said stems having exposed hook means thereon, whereby when said body is disposed between said pair of objects and the latter are pressed together, the stems will penetrate and lodge in said objects to thereby cause said hook means to effect adhesion and join said pair of objects to one another.
