Abstract
Abstract A separable fastener of the press-onipull-off types comprises similar first and second fastener members, each member including a base having a plurality of tapered projections extending from one face surface and a plurality of tapered receptacles recessed into the face surface. Projections and receptacles are positioned in identical patterns and spacings, each projection and receptacle being totally surrounded and isolated by a portion of the base material. The projections on each fastener member are contoured to engage in the receptacles of the other fastener member with a releasable friction fit.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
140 words
A separable fastener of the pr'ess-on/pull-off types comprising: a first fastener member and second fastener member, each said member including a base having a plurality of projections extending from one face surface thereof and a plurality of receptacles recessed into said one face surface thereof, said projections and said receptacles being positioned on said one surface in identical patterns and spacings, each said projection and each said receptacle being totally surrounded and isolated from adjacent projections and receptacles in said patterns by a portion of said base, the projections on each said fastener member being contoured to engage in the receptacles of the other fastener member with a releasable friction fit, said fastener members being engaged when pressed while said one face surfaces are opposed face-to-face and said patterns are aligned at least in part to oppose projections with receptacles.
Claim 2
Dependent Claim
140 words
A separable fastener of the pr'ess-on/pull-off types comprising: a first fastener member and second fastener member, each said member including a base having a plurality of projections extending from one face surface thereof and a plurality of receptacles recessed into said one face surface thereof, said projections and said receptacles being positioned on said one surface in identical patterns and spacings, each said projection and each said receptacle being totally surrounded and isolated from adjacent projections and receptacles in said patterns by a portion of said base, the projections on each said fastener member being contoured to engage in the receptacles of the other fastener member with a releasable friction fit, said fastener members being engaged when pressed while said one face surfaces are opposed face-to-face and said patterns are aligned at least in part to oppose projections with receptacles.
Claim 3
Dependent Claim
95 words
A separable fastener as claimed in claim 1, wherein said receptacles extend from the opposite face surface of said base, said projections being hollow and open at said opposite face surface, said projections extending from said one face surface by a distance equal to the extension of said receptacles from said opposite face surface, said fastener members also becoming engaged when pressed while said one face surface of one member is opposed to said opposite face surface of said second member and with projections and receptacles on said one face surface of said first .
Claim 4
Dependent Claim
41 words
A separate fastener as claimed in claim 2, wherein said projections and said receptacles have equally tapering walls, said releasable friction fit resulting from the wedging engagement of said tapered walls when said first and second fastener members are pressed together.
Claim 5
Dependent Claim
23 words
A separable fastener as claimed in claim 3, wherein said identical patterns comprise longitudinal columns and transverse rows of said projections and receptacles.
Claim 6
Dependent Claim
21 words
A separable fastener as claimed in claim 4, wherein said projections and receptacles are rectangular, longitudinally facing walls having said taper.
Claim 7
Dependent Claim
46 words
A separable fastener as claimed in claim 4, wherein said projections and receptacles are rectangular, longitudinally facing walls having said taper, the transversely facing sides of said projections and receptacles being open and wherein said walls have a taper in the range o'f 15° to 35°.
Claim 8
Dependent Claim
42 words
A separable fastener as claimed in claim 4, wherein said fastener members are strips of extended length in the direction of said columns, said bases extending transversely to.said columns on both sides of said strip, said base extensions forming a protective edge.
Claim 9
Dependent Claim
81 words
A separable fastener as claimed in claim 6, wherein the width of the entrance opening to at least a portion of said receptacles is restricted, said width being measured in the direction of said rows, and the width of said tapered walls in the direction of said rows exceeds the minimum width of said constricted receptacle opening measured in said row direction, and interference being produced between the side edges of said tapered walls and said constricted opening to said receptacle.
Claim 10
Dependent Claim
97 words
A separable fastener as claimed in claim 2, and further comprising a backing strip of finite thickness, one surface of said backing strip having longitudinal channels formed therein, said channels having a depth width, and spacing one from the other to receive therein the extensions of said receptacles from said opposite face surface of said base, said backing strip and said fastener member being joined together with said receptacle extension from said opposite face surface of said base being seated in said grooves, said separable member having only said one face surface with exposed projections and receptacles.
Claim 11
Dependent Claim
50 words
A separable fastener as claimed in claim 2, wherein said first fastener member includes at least one of a projection and receptacle and said second member includes at least one of a mating projection and receptacle such that a connection may be completed between said first and second fastener members.
Claim 12
Dependent Claim
67 words
A separable fastener as claimed in claim 3, wherein the width of the entrance opening to at least a portion of said receptacles is constructed, and the corresponding width of said projections exceeds the minimum width of said constricted receptacle opening, an interference being produced between side edges of said projection and said constricted opening to said receptacle at least during pressing together and separating said members.
Claim 13
Dependent Claim
54 words
A separable fastener as claimed in claim 3, wherein the width of projection walls is extended at least locally and at least locally exceeds the corresponding width of the receptacle opening, an interference being produced between the extended walls and said opening to said receptacles at least during pressing together and separating said members.
