Abstract

Abstract An improvement to touch fastener systems of the type comprising one portion composed of backing material having a hooked surface (14) thereon and another portion composed of backing material having a looped surface (16) thereon. The improvement allows for releasably fastening two components together with the hook and loop materials in shear and is characterized by a planar member (26) having one of the components (14) attached to the end thereof and having outer faces each having one of the portions of the fastening system thereon; and, a U-shaped shear trap channel member (24) having the other of the components attached to the closed end of the U and having inner faces on the sides of the U each having the other of the portions (16) of the fastening system thereon. The shear trap member (24) is adapted to receive the planar member (26) between the inner faces with the portions of the loop fastening portions in engagement; and, is further adapted to have the sides pivoted adjacent the closed end of the U to allow progressive disengagement of the portions of the fastening system.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 119 words
A trap channel member for use with a touch fastener system having releasably engageable parts, providing greater holding strength in a shear direction then in a peel direction CHARACTERIZED by: the trap channel member (30) having opposed inner faces, on the sides (36) of the channel, each having a part of the touch fastener thereon, said trap channel member being able to receive a member having the cooperating other parts of the touch fastener on outer faces thereof between said inner faces with the respective parts in engagement in shear, said trap channel member being adapted to have said inner faces moved outward from one another in a manner to effect progressive disengagement of the parts from one another.
Claim 2
Dependent Claim 119 words
A trap channel member for use with a touch fastener system having releasably engageable parts, providing greater holding strength in a shear direction then in a peel direction CHARACTERIZED by: the trap channel member (30) having opposed inner faces, on the sides (36) of the channel, each having a part of the touch fastener thereon, said trap channel member being able to receive a member having the cooperating other parts of the touch fastener on outer faces thereof between said inner faces with the respective parts in engagement in shear, said trap channel member being adapted to have said inner faces moved outward from one another in a manner to effect progressive disengagement of the parts from one another.
Claim 3
Dependent Claim 44 words
A trap channel member according to claim 1 characterized in that: said trap channel member comprises a resiliently rigid channel member having a back portion and two parallel facing side portions wherein one of the side portions is hingedly attached to said back portion.
Claim 4
Dependent Claim 21 words
A trap channel member according to claim 2 characterized in that: said back portion is adapted for mounting to a surface.
Claim 5
Dependent Claim 23 words
A trap channel member according to claim 2 characterized in that: one of said side portions is adapted for mounting to a surface.
Claim 6
Dependent Claim 28 words
A trap channel member according to claim 2, 3, or 4 characterized in that: said trap channel member has both side portions hingedly attached to said back portion.
Claim 7
Dependent Claim 36 words
A trap channel member according to any preceding claim in that: said hinged side portion is subdivided into a plurality of side members which are each individually pivotable about said hinged attachment to said back portion.
Claim 8
Dependent Claim 28 words
A trap channel member according to any preceding claim characterized in that: said trap channel member is formed of plastic and said hinged attachment comprises a living hinge.
Claim 9
Dependent Claim 42 words
A trap channel member according to claim 7 characterized in that: said side portion attached to said back portion by said living hinge includes a gripping portion whereby said side portion can be gripped to pull the surface portions out of engagement.
Claim 10
Dependent Claim 49 words
A trap channel member according to claim 8 characterized by: a second living hinge disposed longitudinally in said side portion to divide it into a back segment and a front segment which includes said gripping portion and is pivotable to a position wherein it can be more firmly gripped.
Claim 11
Dependent Claim 49 words
A trap channel member according to any preceding claim characterized by: a locking strip adapted to snap over a portion of said trap channel in releasable engagement with said side portions to prevent said side portions from separating and allowing the portions of the fastening system to become disengaged.
Claim 12
Dependent Claim 38 words
A fastening system CHARACTERIZED by: (a) a trap channel member according to any preceding claim, and (b) a planar one of said members having opposed outer faces each having the cooperating other parts of the touch fastener thereon.
