Abstract
A ring binder having D-shaped rings wherein the rings, when opened, position a generally straight leg of the D-shape in a vertical orientation with respect to a horizontal bottom cover panel of the binder. The straight leg has a short turned end portion which allows for simple vertical loading of pages onto the rings. The arrangement provides for greater efficiency at loading multiple pages onto a ring binder in the factory, as well as replacing pages in the ring binder by the consumer. A plurality of D-shaped rings can be used in an arrangement wherein the ring carrier can be mounted on the bottom cover, rather than mounted onto a spine panel of the ring binder. By arranging the ring carrier on the bottom cover rather than the spine, the top and bottom cover members can be made of shorter width, resulting in a savings of material of manufacture.
Claims21
In a D-ring binder having a ring for holding a plurality of pages having ring engaging apertures, wherein said ring is held on a ring carrier, said ring carrier itself held on an inside surface of a cover of a ring binder, the ring having:
- a first ring arm portion extending from a first base end at said ring carrier upwardly away from said inside surface of said cover of said ring binder and terminating in a first distal end;
- and
- a second ring arm portion, said second ring arm portion extending from a second base end at said ring carrier upwardly away from said inside surface of said cover and terminating in a second distal end, said second ring arm portion hingedly held onto said ring carrier and pivotable into an open position away from said first ring arm portion, said ring closeable by pivoting said second ring arm portion with said first distal end closeable to said second distal end, said ring carrier having means for resiliently urging said first distal end and said second distal end closed together, the improvement comprising:
- said second ring arm portion having a substantially straight length, with a short portion adjacent said second distal end, said short portion turned toward said first ring arm portion, said second ring arm portion hingedly held onto said ring carrier and pivotable into an open position away from said first ring arm portion, with the straight length in a substantially vertical position, said short portion having a horizontal profile in an open position less than a corresponding horizontal clearance of said apertures for vertical downward loading of said pages, onto said second ring arm portion, said ring closable by pivoting said second ring arm portion with said fist distal end engageable to said second distal end.

A ring binder for holding pages having apertures therethrough, comprising:
- a top cover portion;
- a spine cover portion;
- a bottom cover portion, said top cover portion hingedly connected to said spine cover portion, said spine cover portion hingedly connected to said bottom cover portion;
- a ring carrier mounted to an inside surface of said bottom cover member;
- at least one ring held on said ring carrier member, said ring having a first ring arm and a second ring arm, said first ring arm and said second ring arm each having base ends and distal ends, said base ends of said ring arms mounted to said ring carrier and said distal ends arranged elevated away from said bottom cover portion and arrangeable to abut together when said ring is in a closed condition
- said ring carrier having means for urging said distal ends together when said ring is in a closed condition;
- and
- said first ring arm comprising a generally concave shape toward said second ring arm, and said second ring arm comprises a shape having a substantially straight length with a short portion adjacent said distal end of said second ring arm, said short portion angled off from said straight length toward said first ring arm, said second ring arm portion hingedly held onto said ring carrier and pivotable into an open position away from said first ring arm portion, with the straight length in a substantially vertical position, said short portion having a horizontal profile in open position less than a corresponding horizontal clearance of said apertures for vertical downward loading of said pages, onto said second ring arm portion.

- and
- said first ring arm comprising a generally concave shape toward said second ring arm, and said second ring arm comprises a shape having a substantially straight length with a short first turned portion adjacent said distal end of said second ring arm, said first turned portion angled off from said straight length toward said first ring arm, said second ring arm portion hingedly held onto said ring carrier and pivotable into an open position away from said first ring arm portion, with the straight length in substantially vertical position, said short portion having a horizontal profile in open position less than a corresponding horizontal clearance of said apertures for vertical downward loading of said pages, onto said second ring arm portion;
- said ring carrier comprises a resilient cover and first and second hinged leaves, hinged together, said resilient cover clasping around an outside dimension of said hinged leaves and resiliently holding said hinged leaves in a V condition either pointed downwardly or upwardly depending on the open or closed condition of said first and second ring arms, said hinged leaves resiliently urging said distal ends together when said ring is in said closed condition, said first ring arm engaged at its base end to said first hinged leave and said second ring arm having its second turned portion arranged between said second hinged leave and said resilient cover and engaged at its base end to said second hinged leave.

A method of loading pages into a ring binder comprising the steps of:
- providing a D-shaped ring having an arcuate first leg and a substantially straight second leg, said first and second legs connected at base ends to a ring carrier, said substantially straight second leg having a short turned portion at a free end thereof, said arcuate leg and said substantially straight leg being pivotable at said ring carrier to selectively spread apart or close together with said short turned portion mating with a free end of said arcuate leg, said ring carrier providing means for resiliently urging said short turned portion and said free end together to hold closed said ring;
- with the D-shaped ring in the open condition, loading a substantially horizontally positioned stack of pages having punched holes in vertical alignment substantially vertically downward onto the substantially straight leg, the straight leg extending substantially vertically and penetrating the holes;
- and
- closing said D-shaped ring.
