Definitions

  • This invention relates to a ring binder mechanism and, in particular, such a mechanism which can be secured to an article, e.g. a cover, to form a pocket diary or organizer for retaining loose-leaf paper.
  • Figs. 1 to 2C show a first type of prior art ring binder mechanism (generally designated as 10), which may be used in such stationery items as ring binders and pocket diaries.
  • the ring binder mechanism 10 includes a retaining structure 12 and a back plate 14. At each end of the retaining structure 12 is a lever 16, which is operable to open and/or close a number of half-rings 18, in the well known manner.
  • the retaining structure 12 includes a pair of plates 20 (to which the half-rings are mounted) supported by a lower curved plate 22. A respective longitudinal edge of the plates 20 abuts each other so that the pair of plates 20 may pivot relative to each other in the usual manner.
  • the lower curved plate 22 includes two cut-out portions 24a, 24b. Each of the cut-out portions 24a, 24b includes a narrower generally rectangular portion and a broader generally rectangular portion.
  • the cut-out portion 24a includes a tongue 26 with a recess 28 on its side facing the back plate 14.
  • the back plate 14 includes two pairs of lugs 30.
  • the two lugs 30 of the same pair are bent outward from each other.
  • a ridge 32 is also provided on the upper surface of the back plate 14.
  • the retaining structure 12 and the back plate 14 are assembled to each other in the following manner.
  • the longitudinal axis of the retaining structure 12 and that of the back plate 14 are disposed substantially parallel to each other, whereby the recess 28 of the tongue 26 slides on and relative to the ridge 32 in the direction indicated by the arrow K.
  • the lugs 30 prevent (a) the curved lower plate 22 from moving any further relative to the back plate 14 in the direction of the arrow K, or (b) the curved lower plate 22 from being pulled apart from the back plate 14.
  • the engagement between the tongue 26 and the ridge 32 also prevents the curved lower plate 22 from moving relative to the back plate 14 in the direction opposite to the arrow K.
  • the curved lower plate 22, and thus the retaining structure 12 is locked with the back plate 14 against any relative movement therebetween.
  • a second type of prior art ring binder mechanism is shown in Figs. 3A to 6E, and generally designated as 100.
  • the second type of prior art ring binder mechanism 100 includes a curved lower plate 102 supporting a pair of plates 104 (shown in broken lines in Fig. 4) which are pivotable relative to each other in order to open and/or close half-rings 106, upon operation of levers 108.
  • the ring binder mechanism 100 includes a generally curved back plate 110 (see Figs. 5A and 5B) to which two upstanding barrels 112 (of which only one is shown in Fig. 4) are secured.
  • a pair of claw rings 114 Secured to the upper surface of the curved lower plate 102 is a pair of claw rings 114.
  • the claw ring 114 includes a generally circular ring portion 116 which is engaged by a lip portion 118 of the curved lower plate 102.
  • the claw ring 114 also includes five claw members 120 which extend generally upwardly away from the ring portion 116.
  • a central opening 122 is thus formed in the central portion.
  • the curved lower plate 102 may be assembled to and engaged with the back plate 110 by first aligning the central opening 122 of each of the claw rings 114 over the respective barrel 112, and subsequently pushing the curved lower plate 102 towards the back plate 110 in the direction indicated by the arrow L in Fig. 6C, whereby the claw members 120 will grip the respective barrel 112, and prevent any relative movement between the curved lower plate 102 and the back plate 110. Because of the orientation of the claw members 120, once the curved lower plate 102 is engaged with the back plate 110 in the manner as shown in Figs.
  • any attempt to pull the curved lower plate 102 away from the back plate 110 in the direction opposite to the arrow L in Fig. C will only tighten the grip of the claw members 120 on the barrels 112, thus preventing the attempt to pull the curved lower plate 102 away from the back plate 110.
  • a disadvantage associated with the first type of prior art ring binder mechanism 10 is that, during assembling, it is necessary to accurately align the retaining structure 12 with the back plate 14 in order to assemble them together.
  • the cover may be made of such materials as genuine leather, imitation leather, cardboard materials, plastics materials etc., which are of different thickness, according to the nature of the materials as well as the size of the pocket diary. Accordingly, a sheet of material of different thickness may have to be disposed between the back plate 14 and the curved lower plate 22 of the respective prior art ring binder mechanisms 10. In order to cater for this situation, the manufacturers have to provide the assemblers with products or components of various sizes, thus increasing the complication of the assembling process.
  • a ring binder mechanism including a base plate and two carrier rails, wherein said carrier rails are arranged in a resilient casing member and bear against each other, the angle formed between said carrier rails changing during opening and closing of half ring members associated with said carrier rails, said base plate being adapted to be secured to an article, wherein said base plate is securable with said casing member in a snap-fit manner.
  • a ring binder mechanism including a base plate and two carrier rails, wherein said carrier rails are arranged in a resilient casing member and bear against each other, the angle formed between said carrier rails changing during opening and closing of half ring members associated with said carrier rails, wherein said base plate is engageable with said casing member, wherein said base plate is adapted to be secured to an article at least part of which being disposed between said base plate and said casing member, wherein said base plate includes at least one resilient member extending generally towards said casing member, or wherein said casing member includes at least one resilient member extending generally towards said base plate.
  • a first embodiment of a ring binder mechanism according to the present invention is shown in Fig. 7 to 9 as generally designated as 200.
  • the ring binder mechanism 200 includes a structure 202 for retaining loose-leaf paper, and a curved back plate 204.
  • such includes a pair of elongate carrier plates 206 which abut each other along one of their respective lateral edges.
  • the elongate plates 206 are supported by a resilient curved lower plate 208.
  • Mounted with each of the plates 206 are a number of half-ring members 210.
  • the plates 206 may be caused to pivot to open and/or close the pairs of half-ring members 210, during which the angle formed between the elongate plates 206 changes, as in the usual manner.
  • a curved upper cover 214 is also provided.
  • the upper cover 214 includes a number of side openings 216 through which the half-ring members 210 may extend. As shown more clearly in Figs. 9 and 10, the curved lower plate 208 includes two rows of loops 218, through each row a wire 220 may be received.
  • Figs. 11A to 11E show various views of the curved back plate 204. It can be seen that two lug members 222, which are integral with the back plate 204, extend generally upwardly from the back plate 204. As can be seen more clearly in Fig. 11D, the lug member 222 includes a semi-circular upper portion 224 with a rectangular lower portion 226, which is joined with the back plate 204. On the upper surface of the back plate 204 are provided two cylindrical protrusions 228.
  • Figs. 12A to 12E showin more detail the engagement between the wires 220 and the curved lower plate 208.
  • the lower plate 208 includes two openings 230 through which the lug members 222 are receivable.
  • the lower plate 208 includes two apertures 232 for receiving the cylindrical protrusions 228, as shown in Fig. 10.
  • Two resilient and generally trapezoidally-shaped tongue members 234, which are integrally formed with the back plate 204, extend generally towards each other and away from the bottom surface of the back curved lower plate 208. The function of these tongue members 234 will be explained below.
  • the retaining structure 202 is placed above the back plate with their respective longitudinal axis disposed substantially parallel to each other, with the openings 230 above the respective lug members 222, and with the apertures 232 over the respective cylindrical protrusion 228.
  • the region of the wires 220 acted upon the semi-circular portion 224 of the lug member 228 will be forced to move apart from each other.
  • the wires 220 pass through the semi-circular portion 224, they will snap back and grip on the rectangular portion 226 of the lug member 228.
  • the retaining structure 202 can be easily and safely secured to the back plate 204 in a snap-fit manner.
  • elongate plates 206 are provided with recesses 236.
  • the respective recesses 236 of the plates 206 form a continuous opening which allow the respective lug member 222 to pass through when the half-ring members 210 are in the closed configuration.
  • Figs. 13 to 14E show a second embodiment of a ring binder mechanism according to the present invention as generally designated as 300. While most of the construction and components of this ring binder mechanism 300 are essentially the same as those of the ring binder mechanism 200, it can be seen that, instead of two long wires, four shorter wires 302. It can be readily realized that the mode of operation of the ring binder mechanism 300 is very much the same as that of the ring binder mechanism 200, such that no further elaboration thereof is believed not necessary.
  • the back plate 204 is usually embedded in the cover of the ring binder or pocket diary.
  • a sheet of material is disposed between the back plate 204 and the retaining structure 202.
  • Figs. 15A and 15B show the engagement between the back plate 204, the retaining structure 202 and a sheet of material 238, e.g. leather.
  • the sheet of material 238, which contains an opening 240 is placed between the retaining structure 202 and the back plate 204.
  • lug member 222 When the retaining structure 202 moves towards the back plate 204 in the direction of the arrows N, the lug member 222 extends through the opening 240 and into the interior cavity formed by the upper casing 214 and the lower plate 208 of the retaining structure, and be locked by the wires 220.
  • Fig. 15B shows the retaining structure 202, the sheet of material 238 and the back plate 204 as secured to one another.
  • the curved lower plate 208 includes tongue members 234 which extend towards each other and away from the lower surface of the lower plate 208.
  • the tongue members 234 assist in allowing the ring binder mechanism 200 in catering for materials of different thickness.
  • Figs. 16A and 16B show the attachment of the ring binder mechanism 200 to a thinner material 238a. It can be seen that the tip portion of the tongue member 234 abuts against the material 238a.
  • Figs. 16C and 16D show the attachment of the ring binder mechanism 200 to a thicker material 238b.
  • the tongue member 234 While the tip portion of the tongue member 234 also abuts against the material 238b, the tongue member 234 is caused by the material 238b to deform and move closer towards the lower surface of the lower plate 208. It can be seen that the retaining structure 202, the back plate 204 and the sheet material 238, 238a, 328b can be safely secured to one another irrespective of the thickness of the sheet material 238, 238a, 328b.
  • ring binder mechanism 200 is used as the example in explaining the way in which the ring binder mechanism of the present invention may cater for materials of different thickness, it should of course be understood that the ring binder mechanism 300 can also achieve the same result.
