Abstract:
A â€œcrownâ€  fastener for securing a binder ring mechanism to a binder cover comprising:a fastener body having a surface at one end for attaching said fastener to said binder mechanism by abutting said surface against said binder mechanism and then deforming a portion of said binder mechanism and said surface about each other to capture them together; a first set of prongs projecting from an opposite end of the fastener body for attaching said fastener to the binder cover by positioning said prongs adjacent a portion of the cover and then engaging said prongs with said portion of the cover for said prongs to secure said fastener thereto; and, a second set of prongs also formed at the opposite end of the body and projecting therefrom, said second set of prongs also engaging said portion of the binder cover to increase the holding strength of the fastener and prevent twisting of the mechanism once attached to the binder thereby to lessen the tendency of the mechanism from subsequently being separated from the cover, the prongs forming the first set extending outwardly from a longitudinal axis of the fastener, and the prongs forming the second set extending inwardly toward the longitudinal axis.
