Abstract
Abstract A fastener to permit the capture and release by a selected medium of the wire binder on notebooks, tablets, or the like. The fastener includes a series of tabs which are profiled so that the captured medium resists removal due to ordinary stresses, but may be inserted and removed by means of an easily applied transverse force.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
84 words
A member for removable attachment to a binder comprising a tab and a backing spaced therefrom; said tab having a hook which defines an aperture with said backing and is bendable out of the plane of the member for receiving and engaging the binder; said backing having an edge that extends diagonally tangential from the aperture and defines an open gap terminating in an open notch at the outer edge with respect to said tab for the passage of the binder into said aperture.
Claim 2
Dependent Claim
84 words
A member for removable attachment to a binder comprising a tab and a backing spaced therefrom; said tab having a hook which defines an aperture with said backing and is bendable out of the plane of the member for receiving and engaging the binder; said backing having an edge that extends diagonally tangential from the aperture and defines an open gap terminating in an open notch at the outer edge with respect to said tab for the passage of the binder into said aperture.
Claim 3
Dependent Claim
18 words
The member of claim 1 wherein said tab and backing are essentially flat and attachable to a base.
Claim 4
Dependent Claim
19 words
The member of claim 2 wherein said tab is not easily distortible within said plane, but is transversely flexible.
Claim 5
Dependent Claim
35 words
The member of claim 3 wherein the gap between said tab and said backing has a width when said tab is undistorted which is less than the thickness of a coil of a spiral binder.
Claim 6
Dependent Claim
17 words
The member of claim 1 wherein said tab and said backing are comrpised of a plastics material.
Claim 7
Dependent Claim
18 words
The member of claim 1 wherein said aperture is essentially circular, with a diameter of about 0.125 inch.
Claim 8
Dependent Claim
24 words
The member of claim 1 wherein the hook has an edge facing the backing which is shorter than the minimum dimension of said aperture.
Claim 9
Dependent Claim
20 words
The member of claim 1 wherein the hook extends to a tip with an included angle of less than 45°.
Claim 10
Dependent Claim
28 words
The member of claim 21 wherein said tab and said backing have edges opposite points of attachment to a base which define a V-notch terminating at said gap.
Claim 11
Dependent Claim
21 words
The member of claim 1 forming each of a series of tab-backing pairs attached to a base in a linear array.
Claim 12
Dependent Claim
20 words
The member of claim 10 wherein said tab-backing pairs are spaced on said base at intervals of about 1 inch.
Claim 13
Dependent Claim
25 words
The member of claim 10 wherein the relative position of the tab and backing in each of said tab-backing pairs alternates from pair to pair.
Claim 14
Dependent Claim
24 words
The member of claim 10 wherein said base comprises a marginal strip suitable for binding a specimen to be attached to a wire binder.
Claim 15
Dependent Claim
14 words
The member of claim 10 wherein said marginal strip is coated with an adhesive.
Claim 16
Dependent Claim
30 words
The member of claim 10 wherein said base comprises a specimen suitable for carriage in a wire binder, in one edge of which said tabs and backing members are perforated.
Claim 17
Dependent Claim
38 words
The member of claim 11 forming one of a series of tabs attached to a base in a linear array, such that a portion of each tab remote from its aperture comprises a backing for an adjacent tab.
Claim 18
Dependent Claim
22 words
The member of claim 16 wherein tabs are spaced at intervals corresponding to the separation of coils in a given coil pitch.
Claim 19

24 words
The member of claim 16 wherein said base comprises a marginal strip suitable for binding a specimen to be attached to a wire binder.
Claim 20
Dependent Claim
14 words
The member of claim 18 wherein said marginal strip is coated with an adhesive.
Claim 21
Dependent Claim
30 words
The member of claim 16 wherein said base comprises a specimen suitable for carriage in a wire binder, in one edge of which said tabs and backing members are perforated.
