Abstract
A convertible ring binder incorporates front and back covers that are detachable one from the other to enable exchange of the covers for new or different covers. Hook and loop material is utilized to effect detachable attachment of the covers. In another aspect, the ring structure utilized to store paper in the binder is detachably secured to the spine of a loose-leaf ring binder.
Claims8
A convertible ring binder of the type used to store sheets of paper, comprising:
- a) a front cover having a spine portion pivotally mounted thereon along one edge thereof;
- b) a back cover having a spine portion pivotally mounted thereon along one edge thereof;
- c) ring means mounted on one of said spine portions manipulable to engage or release one or more sheets of paper;
- and
- d) means on said spine portions selectively engageable and disengageable to operatively associate said spine portions and said front and back covers to form a composite binder selectively convertible by the substitution of one cover for another;
- e) said means on said spine portion engageable and disengageable to cooperatively associate said spine portions comprising hook and loop members mounted on said spine portions.
