First Claim

1. A fastener including upstanding mating hooking elements of the hook-type and loop-type having the property that when a plurality of such hooking elements are placed in face-to-face relation with a plurality of mating hooking elements numerous engagements of the hooking elements take place and the elements resist separation by forces substantially parallel to the interfacial plane of engagement, comprising:
- (a) at least first and second fastener members, each having at least one surface containing hooking elements capable of mating with the hooking elements of the other; and
(b) substantially rigid structural members secured to said fastener members for positioning said fastener members such that said surfaces are maintained in substantially rigid parallel relation and confined in a substantially fixed spaced relationship, which space is sufficiently less than the combined height of the hooking elements upstanding from both surfaces such that at least certain of the hooking elements are brought into a hook and loop-type engaged relation by forcibly directing the hooking elements of at least one of said fastener members in a direction generally normal to the projection of said hooking elements such that interposition of a third member between said surfaces over at least a portion of the engagement area of said hooking elements without physically destroying a substantial portion of the engaged hooking elements in said area is thereby precluded, such that relative movement of the fastener members is confined generally along the direction perpendicular to the projection of said hooking elements, and attachment and detachment of the respective members is achieved only by forces substantially parallel to the respective surfaces of said fastener members in sufficient magnitude to overcome the progressive resistance of the hooking elements progressively engaging and disengaging as they are moved relative to each other.

- 4. The fastener according to claim 15 wherein said hooking elements are disposed on opposed surfaces of said structural members in the form of fastener tapes secured thereto, said tapes having said hooking elements extending upwardly from a surface thereof.
-
12. The fastener according to claim 20 wherein one of said cylindrical tubular members mounts at least one fastener tape containing hooking elements in the form of loops and the other mounts at least one fastener tape containing hooking elements in the form of hooks, all of the hooks of said hook fastener tape being oriented in a direction to resist disengagement after the tubular member is received within said cylindrical member due to the progressive interference shear resistance of said hooks and loops.

13. A fastener including upstanding mating hooking elements of the hook-type and loop-type having the property that when a plurality of such hooking elements are placed in face-to-face relation with a plurality of mating hooking elements numerous engagements of the hooking elements take place and the elements resist separation by forces substantially parallel to the interfacial plane of engagement, comprising:
-
(a) at least first and second fastener tapes each having at least one surface having a plurality of hooking elements upstanding therefrom and defining a respective mating surface; and (b) substantially rigid structural members secured to said fastener tapes for positioning said fastener tapes such that the mating surfaces of said fastener tapes are maintained in substantially rigid parallel relation and confined in a substantially fixed spaced relationship, which space is sufficiently less than the combined height of the hooking elements upstanding from both surfaces of said tapes such that at least certain of the hooking elements are brought into a hook and loop-type engaged relation by forcibly directing the hooking elements of at least one of said fastener tapes in a direction generally normal to the projection of said hooking elements such that interposition of a third member between said fastener tapes over at least a portion of the engagement area of said hooking elements without physically destroying a substantial portion of the engaged hooking elements in said area is thereby precluded, such that relative movement of the members is physically confined generally along the direction normal to the projection of said hooking elements, and attachment and detachment of the respective members is achieved only by forces substantially parallel to the respective mating surfaces of said fastener tapes in sufficient magnitude to overcome the progressive resistance of the hooking elements progressively engaging and disengaging as the structural members are moved relative to each other. - View Dependent Claims (9, 10, 11)
