Abstract
A fastener (30) for fastening a paper retaining binder mechanism (18) to the spine (16) of a binder (10) and remaining entirely concealed from an outer surface of the binder. The fastener includes a circular anchor plate (38) and a vertically extending attachment post or eyelet (34). The post is a truncated cone of uniform taper. The anchor plate includes a circumferential reinforcing lip (48). The fastener is secured to the spine by a number of spurs (50) uniformly spaced about the circumference of the anchor plate. The eyelet extends perpendicular of the anchor plate and the binder mechanism seats on the eyelet by an opening (26, 28). The upper end of the eyelet is then deformed about the opening to secure the binder mechanism in place.
Claims17
A fastener for fastening a paper retaining binder mechanism to a binder comprising:
- an anchor plate on which are formed a plurality of spurs for securing the fastener to a spine of the binder;
- and,
- an eyelet integrally formed with said anchor plate and projecting outwardly therefrom for an opening on said binder mechanism to be seated on said eyelet, said binder mechanism being secured to said fastener by deforming an end of said eyelet about said opening after said binder mechanism is in place;
- said anchor plate being a circular plate with said spurs being uniformly spaced around the circumference thereof for engaging said spine to secure said fastener thereto, the circularity of said plate allowing said fastener to be placed in any orientation on said spine prior to securing said fastener to said spine without effecting the secureness of the fastener to the spine or the binder mechanism to the fastener.

- and,
- an eyelet integrally formed with said anchor plate and projecting outwardly therefrom for an opening on said binder mechanism to be seated on said eyelet, said eyelet comprising a hollow post having a truncated cone shape with the proximal end of the post having a larger diameter than the distal end thereof, said post being uniformly tapered throughout its length, and said binder mechanism being secured to said fastener by deforming an end of said eyelet about said opening after said binder mechanism is in place.
