Definitions

  • This invention relates to a ring binder, and in particular a ring binder adapted to be secured by at least one securing means to a cover.
  • a ring binder is securable to a cover by at least one rivet having a head portion for engagement with the cover and a tail portion which is deformable to engage a recess in the upper part of the ring binder.
  • Europeant Patent Document No. 0 226 297 A3 discloses a binder having a non-metallic cover and a binding assembly for retaining sheets.
  • the assembly is attached to the inner surface of the cover by a plurality of prongs that are each stamped or punched out of a metal attachment plate.
  • Each prong is generally triangular in shape and is curved throughout its length and terminates in a sharpened tip.
  • the metal attachment plate may comprise a portion of a hinge assembly, or may be a binding plate attached to the rear face of a toggled binder mechanism.
  • Figs. 6 and 7 of this document shows a three-ring binder mechanism incorporating a rear binding plate which extends along substantially the entire length of the binder mechanism.
  • the rear binding plate has prongs which are driven into a cover during assembly, in order to secure the ring binder mechanism to the cover.
  • US Patent No. 5,160,209 discloses a fastener for fastening a paper retaining binder mechanism to an inner surface of a binder while remaining entirely concealed from an outer surface of the binder.
  • the fastener includes an anchor plate and a post which extends directly away from the anchor plate. While the post engages with a top cover of the paper retaining binder mechanism, the anchor plate includes prongs which are driven into a cover. By way of such an arrangement, the paper retaining binder mechanism may be secured to the cover.
  • a disadvantage associated with such arrangements is that it is necessary to manufacture and provide the assemblers with both the ring binders and correspondingly shaped and sized rivets suitable for securing the ring binder to the cover. Rivets of a wrong size or shape may be erroneously provided to the assemblers. The assembling process is also laborious and prone to error. In particular, if the riveting action is not properly carried out, the ring binder and/or the cover may be damaged.
  • a ring binder adapted to be secured to a base member, which ring binder comprises a substantially rigid upper structure supporting a pivotable lower structure to which a plurality of ring members are mounted, characterized in that said ring binder comprises at least one securing means integrally formed with said upper structure and adapted to secure said ring binder to said base member.
  • the upper structure may conveniently slope downward at each end.
  • the securing means may advantageously be deformable to secure the ring binder to the base member.
  • the securing means may comprise a plurality of deformable securing members, each comprising a pointed element pointing downward from the upper structure.
  • the pointed elements may depend downward from the periphery of an opening in the upper structure and point outward from the central longitudinal axis of the opening, which may be substantially circular or hexagonal.
  • a ring binder according to the present invention generally designated as 100 includes a substantially rigid upper plate member 102 supporting a pair of pivotable lower plates 104 a and 104 b .
  • the lower plates 104 a and 104 b are pivotably movable relative to each other to enable rings 106 to be selectively opened or closed in the conventional manner.
  • the claws 108 are integrally formed with the upper plate member 102.
  • the claws 108 are pushed out from the upper plate member 102 and apertures 110, shown in Fig. 3 as substantially hexagonal, are formed.
  • the claws 108 extend downward from the upper plate member 102 and outward from the longitudinal axis of the aperture 110.
  • the claws 108 are shown in Fig. 5 as pressed into a, e.g., cardboard cover 112. As the claws 108 are splayed out in the pressing process, the connection between the ring binder 100 and the cover 112 is further enhanced.
  • a second embodiment of a ring binder according to the present invention is shown as generally designated as 200. Similar to the first embodiment described above, the ring binder 200 includes a substantially rigid upper plate member 202 supporting a pair of pivotable lower plates 204 a and 204 b . The lower plates 204 a and 204 b are pivotably movable relative to each other to enable rings 206 to be selectively opened or closed in the conventional manner.
  • the claws 208 are integrally formed with the upper plate member 202.
  • the claws 208 are pushed out from the upper plate member 202 and apertures 210, shown in Fig. 11 as substantially circular, are formed.
  • the claws 208 extend downward from the upper plate member 202 and outward from the longitudinal axis of the aperture 210.
  • the claws 208 are shown in Fig. 12 as pressed into a, e.g., cardboard cover 212. As the claws 208 are splayed out in the pressing process, the connection between the ring binder 200 and the cover 212 is further enhanced.
  • Figs. 13 and 14 show a third embodiment of a ring binder according to the present invention generally designated as 300.
  • the ring binder 300 includes a substantially rigid upper plate member 302 supporting a pair of pivotable lower plates 304 a and 304 b .
  • the lower plates 304 a and 304 b are pivotably movable relative to each other to enable rings 306 to be selectively opened or closed in the conventional manner.
  • the claws 308 are integrally formed with the upper plate member 302.
  • the claws 308 are pushed out from the upper plate member 302 and apertures 310 are formed.
  • the claws 308 extend downward from the upper plate member 302 and outward from the longitudinal axis of the aperture 310.
  • the claws 308 are shown in Fig. 18 as pressed into a, e.g., cardboard cover 312. As the claws 308 are splayed out in the pressing process, the connection between the ring binder 300 and the cover 312 is further enhanced.
  • this invention dispenses with the use of any rivet, which necessitates a separate riveting step in the assembling process.
  • the existence of rivets may also hurt workers and/or users.
  • the absence of any rivet on the outer surface of the cover also helps improve the appearance of the cover. It is also found that such an arrangement can withstand a pulling force of 80 lbs. before the ring binder is detached from the cover.
  • each end of the ring binder may comprise one or three sets of claws, as different circumstances may require.
