Claims
- 1. A “crown” fastener for securing a binder ring mechanism to a binder cover comprising:
a fastener body engaging said binder mechanism to attach the fastener thereto; a first set of prongs projecting from the fastener body for attaching said fastener to the binder cover by engaging said prongs with said cover to secure said fastener thereto; and, a second set of prongs also projecting from the fastener body and engaging said 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.
- 2. The fastener of claim 1 in which the prongs forming the second set are intermediate the prongs forming the first set.
- 3. The fastener of claim 2 in which the prongs forming the first set extend outwardly from a longitudinal axis of the fastener, and the prongs forming the second set extending inwardly toward the longitudinal axis.
- 4. The fastener of claim 1 in which the prongs forming the second set are shorter in length than the prongs forming the first set.
- 5. The fastener of claim 1 wherein the length of the prongs forming the second set is equal to or less than the thickness of a backing material forming the binder cover and into which the prongs are driven to attach the fastener to the binder.
