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.
Claims21
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.
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.
Dependencies are inferred from the claim text.
