Abstract
Abstract A substantially planar, omega-shaped flexible fastener having a resilient spring-like, loop-shaped body portion with integrally formed end portions that terminate in oppositely facing hook-like segments. Each hook-like segment has at least one notch formed therein which mechanically cooperates with the notch formed in the other hook-like segment when the segments are intertwined and stress is applied to the loop-shaped body portion by outwardly acting forces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
A flexible substantially planar, omega-shaped fastener comprising a resilient spring-like, loop-shaped body portion having planar front and back surfaces and integrally formed end portions which each terminate in oppositely facing hook-like segments, said hook-like segments each having a concave portion in which at least one inwardly extending notch is formed with each of said notches having a hook-end surface and a valley surface so that when said hook-like segments are intertwined in an interlocked position, the valley surface of the notch in one hook-like segment contacts the valley surface of the notch in the other hook-like segment and the hook-end surface of the notch in said one hook-like segment contacts the front surface of said other hook-like segment while the hook-end surface of the notch in said other hook-like segment contacts the back surface of said one hook-like segment.
Claim 2
Dependent Claim
139 words
A flexible substantially planar, omega-shaped fastener comprising a resilient spring-like, loop-shaped body portion having planar front and back surfaces and integrally formed end portions which each terminate in oppositely facing hook-like segments, said hook-like segments each having a concave portion in which at least one inwardly extending notch is formed with each of said notches having a hook-end surface and a valley surface so that when said hook-like segments are intertwined in an interlocked position, the valley surface of the notch in one hook-like segment contacts the valley surface of the notch in the other hook-like segment and the hook-end surface of the notch in said one hook-like segment contacts the front surface of said other hook-like segment while the hook-end surface of the notch in said other hook-like segment contacts the back surface of said one hook-like segment.
Claim 3
Dependent Claim
21 words
The fastener of claim 1 further characterized by a plurality of notches formed in the concave portion of each hook-like member.
Claim 4
Dependent Claim
27 words
The fastener of claim 2 wherein said pluralities of notches are defined by corresponding pluralities of counter-pitched teeth formed in the concave portions of said hook-like segments.
Claim 5
Dependent Claim
28 words
The fastener of claim 1 wherein said hook-like segments are in planes which are substantially normal to each other when said segments are intertwined in an interlocked position.
