Abstract
Abstract A press-on and split-off type fastener is constructed of a plurality of corrugated strips of fixed width having alternate uniformly-shaped curved ridges and flat portions of uniform length by arranging such strips in parallel with a fixed phasal relationship between the strips so as to form a protruding type joining surface on one side and a hollow type joining surface on the other side. Closure is possible either between two protruding type joining surfaces or between a protruding type joining surface and a hollow type joining surface and the hollow type joining surface presents a flat surface by which the fastener can be attached to other materials.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
A press-on, separable fastener comprising: first and second facing portions, each of said portions having a support member, and a set of adjoining longitudinal parallel strips on said support member, each of said strips providing a series of spaced apart ridges protruding from said support member, each of said strips containing a series of spaces, each of said spaces being between two successive ones of said ridges, within each of said portions, adjoining ones of said strips being longitudinally staggered relative to each other such that said ridges and spaces of adjoining strips are alternately juxtaposed, the edges of said ridges of said first portion frictionally engaging the edges of said ridges of said second portion when said portions are engaged.
Claim 2
Dependent Claim
121 words
A press-on, separable fastener comprising: first and second facing portions, each of said portions having a support member, and a set of adjoining longitudinal parallel strips on said support member, each of said strips providing a series of spaced apart ridges protruding from said support member, each of said strips containing a series of spaces, each of said spaces being between two successive ones of said ridges, within each of said portions, adjoining ones of said strips being longitudinally staggered relative to each other such that said ridges and spaces of adjoining strips are alternately juxtaposed, the edges of said ridges of said first portion frictionally engaging the edges of said ridges of said second portion when said portions are engaged.
Claim 3
Dependent Claim
121 words
A press-on, separable fastener comprising: first and second facing portions, each of said portions having a support member, and a set of adjoining longitudinal parallel strips on said support member, each of said strips providing a series of spaced apart ridges protruding from said support member, each of said strips containing a series of spaces, each of said spaces being between two successive ones of said ridges, within each of said portions, adjoining ones of said strips being longitudinally staggered relative to each other such that said ridges and spaces of adjoining strips are alternately juxtaposed, the edges of said ridges of said first portion frictionally engaging the edges of said ridges of said second portion when said portions are engaged.
Claim 4
Dependent Claim
121 words
A press-on, separable fastener comprising: first and second facing portions, each of said portions having a support member, and a set of adjoining longitudinal parallel strips on said support member, each of said strips providing a series of spaced apart ridges protruding from said support member, each of said strips containing a series of spaces, each of said spaces being between two successive ones of said ridges, within each of said portions, adjoining ones of said strips being longitudinally staggered relative to each other such that said ridges and spaces of adjoining strips are alternately juxtaposed, the edges of said ridges of said first portion frictionally engaging the edges of said ridges of said second portion when said portions are engaged.
Claim 5
Dependent Claim
46 words
The fastener of claim 1 further comprising: a plurality of projections, each of said projections extending laterally from said ridges of at least said first portion, projections on the ridges in said first portion underlying the ridges on said second portion when said portions are engaged.
Claim 6
Dependent Claim
19 words
The fastener of claim 1 wherein each of said longitudinal parallel strips is laminated to the associated support member.
Claim 7
Dependent Claim
15 words
The fastener of claim 3 wherein support members of each of said portions is flexible.
Claim 8
Dependent Claim
20 words
The fastener of claim 1 wherein said projections extend out from both edges of ridges on each of said portions.
Claim 9
Dependent Claim
16 words
The fastener of claim 2 wherein said projections lie in a direction having a lateral component.
Claim 10
Dependent Claim
12 words
The fastener of claim 1 wherein said strips are of equal width.
Claim 11
Dependent Claim
111 words
A separable fastener member comprising: a planar support member, a sheet of resilient material in the form of an integral field of plural adjoining longitudinal strips on said support member, the strips undulating in an alternating series of arches anD spaces, said arches protuberant from said support member, said spaces interposed between said arches, the adjoining strips being staggered relative to each other such that the arches and spaces of adjoining strips are alternately juxtaposed, the spaces serving to receive the protuberant arches of a facially superposed substantially identical field, the edges of said arches serving to frictionally engage the edges of the arches of a facially superposed substantially identical field.
Claim 12
Dependent Claim
111 words
A separable fastener member comprising: a planar support member, a sheet of resilient material in the form of an integral field of plural adjoining longitudinal strips on said support member, the strips undulating in an alternating series of arches anD spaces, said arches protuberant from said support member, said spaces interposed between said arches, the adjoining strips being staggered relative to each other such that the arches and spaces of adjoining strips are alternately juxtaposed, the spaces serving to receive the protuberant arches of a facially superposed substantially identical field, the edges of said arches serving to frictionally engage the edges of the arches of a facially superposed substantially identical field.
Claim 13
Dependent Claim
55 words
The separable fastener of claim 8 wherein: the side edges of at least some of the arches having tabs which project in a direction having a lateral component, the projecting tabs of each field overlying those of a facially superposed field to resiliently retain the arches of each field in the spaces of the other.
Claim 14
Dependent Claim
15 words
The separable fastener of claim 8, wherein said strips are laminated on said support member.
