Abstract

Abstract An improvement is provided for a releasable, flexible fabric hook and loop fastener having a pair of strap ends which are adapted for mutually releasable interengagement to form a loop when disposed in facing, overlapping arrangement in contact with each other. According to the improvement, the contact surface on the innermost of the strap ends does not extend to the extremity of the strap end, but terminates short of it, thereby defining a tip which is not engageable with the contact surface of the outermost strap end. When the outermost strap end is peeled away from the innermost strap end, the tip on the innermost stap end allows the contact surfaces to separate cleanly so that the fastener can be opened with one hand.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 215 words
A releasable fastener having inner and outer strap ends releasable securable together to form an encircling loop and wherein said inner strap end has an edge extremity folded outwardly and back upon itself where it is secured to form a return which defines a tip of double thickness at least one quarter of an inch wide and an outwardly facing contact surface which terminates at said tip of said inner strap end, and said outer strap end also has an edge extremity folded back upon itself in a return which defines a gripping tab of double thickness which is seizable between the thumb and forefinger of a single hand and said outer strap end has an inwardly facing contact surface, and one of said contact surfaces bears a multiplicity of projecting flexible hooks and the other of said contact surfaces bears a flexible looped pile, and said contact surfaces are positionable in juxtaposition, whereby said hooks are releasably engageable in said pile and said contact surfaces are separable using the fingers of a single hand to peel back said outer strap from said inner strap such that said tip of said inner strap acts as a short lever which aids in prying apart the last remaining mutually engaged hooks and loops of said contact surfaces.
Claim 2
Dependent Claim 215 words
A releasable fastener having inner and outer strap ends releasable securable together to form an encircling loop and wherein said inner strap end has an edge extremity folded outwardly and back upon itself where it is secured to form a return which defines a tip of double thickness at least one quarter of an inch wide and an outwardly facing contact surface which terminates at said tip of said inner strap end, and said outer strap end also has an edge extremity folded back upon itself in a return which defines a gripping tab of double thickness which is seizable between the thumb and forefinger of a single hand and said outer strap end has an inwardly facing contact surface, and one of said contact surfaces bears a multiplicity of projecting flexible hooks and the other of said contact surfaces bears a flexible looped pile, and said contact surfaces are positionable in juxtaposition, whereby said hooks are releasably engageable in said pile and said contact surfaces are separable using the fingers of a single hand to peel back said outer strap from said inner strap such that said tip of said inner strap acts as a short lever which aids in prying apart the last remaining mutually engaged hooks and loops of said contact surfaces.
