Definitions

  • This invention relates to a ring binder for loose-leaf binders and the like.
  • Such ring mechanisms suffer from the problem that the mechanism can be difficult to open, particularly large paper ring mechanisms which have a large closing force to prevent paper falling off the rings.
  • Some known ring mechanisms have attempted to overcome this problem. However, they are complicated in design and have to be manually assembled during manufacture.
  • a ring binder in accordance with the invention, includes a base member supporting a plurality of ring members, and an opening mechanism at each end of the base member for opening the plurality of ring members, each opening mechanism including lock means to lock the opening mechanisms in their closed position, the base member comprising a rigid upper structure supporting a pivotable lower structure to which the ring members are mounted, characterised in that at each end of the binder, the opening mechanism is pivotally supported between the lower structure and the upper structure, externally of the lower structure, and internally of the upper structure.
  • the advantage of locking the ring members is that the ring binder is easy to open once unlocked and the sheets of paper in the ring binder will not become detached from the ring members, whilst the advantage of supporting the opening mechanism externally of the lower structure and internally of the upper structure is that the ring binder can be automatically assembled by a machine.
  • the base of the opening mechanism acts on the underneath of the pivotable lower structure to force this structure to move upwards and pivot, thereby causing the ring members mounted thereto to separate from each other, and open out.
  • the lock means comprises a ledge member which cooperates with a corresponding lug member provided on the underneath of the upper structure.
  • the ledge member is disengaged from the lug member.
  • the lock means comprises a part of the opening mechanism being positioned over centre between the upper and lower structure of the base member.
  • a ring binder 10 is shown for a loose-leaf binder comprising a base member 12, three ring members 14 spaced along the base member (one of which is shown in Figures 4 & 5), and an opening and locking mechanism 20 at each end of the base member (only one of which is shown).
  • the base member 10 comprises an upper rigid structure 24 which is curved in cross-section and which supports between its two overlapping sides 26 a pivotable lower structure 30 comprising two carrier rails 32 pivotable to each other along the longitudinal axis of the binder 10.
  • the ring members 14 are mounted on the pivotable lower structure 30 and in particular, one of the ring components (ie component 14a) of each ring member is mounted on the carrier rail 32 while the other ring component (not shown) of each ring member is mounted on the other carrier rail (also not shown).
  • Fastening means 34 are also provided on the upper structure 24 in order to secure the ring binder 10 to a paper folder or the like.
  • the two carrier rails 32 are movable (ie pivoted) relative to each other between a lower position and an upper position due to the action of the opening and locking mechanism 20 on each end of the carrier rails.
  • the opening mechanism 20 is pivotably supported on each end of the upper rigid structure 24 and is in engagement with each end of the pivotable lower structure 30 in order to position the opening mechanism 20 between the upper and lower structures.
  • two projections 33 and 35 one above the other (see Figures 4 and 5) on each side of the opening mechanism 20 are provided which are internally enclosed by the crimped end 37 of each side 26 of the upper structure 24, while the projections 33 and 35 are externally placed on top of and below, respectively, the outer side ends 39 of the carrier rails 32 in order to engage and position the lower structure 30 relative the upper structure 24, and to pivotally support the opening mechanism 20 between the lower structure 30 and the upper structure 24.
  • the opening mechanism 20 is supported between the upper and lower structure to allow pivotal movement, but otherwise is fixedly mounted therebetween (ie no lateral movement etc).
  • the whole outer ends of the upper structure 24 are substantially unobstructed with downwardly depending flaps and the like.
  • the opening mechanism 20 to assemble the opening mechanism 20 to the ring binder, one only needs to place the opening mechanism 20 directly between the upper and lower structures 24 and 30, and then to crimp (ie pinch) together the overlapping end 37 of each side 26 of the upper structure. Since the outer ends of the upper structure 24 are substantially unobstructed with downwardly depending flaps and the like, the additional advantage of saving of material is achieved. In this respect, between 2 and 4% saving of material over known arrangements can be obtained.
  • the ring binder has a locked position (see Figure 1) and two unlocked positions (see Figures 2 and 3).
  • the opening mechanism 20 on each end is provided with a first ledge member 36 for cooperating with a lug 38 on the underneath of the upper rigid structure 24 of the base member.
  • the ring binder has two closed positions (see Figures 1 and 3) and an open position (see Figure 4).
  • the opening mechanism 20 is provided with a second ledge member 40 which is engageable with the underneath of the two pivotable carrier rails 32.
  • locking is achieved by the ledge member 36 cooperating with the lug 38 such that in the closed and locked position (see Figure 1), the ledge member 36 is positioned on one side of the lug 38 whilst in the unlocked position (see Figure 2), the ledge member 36 is positioned on the other side of the lug 38.
  • the ledge member 40 In the closed and locked position, the ledge member 40 is not in contact with the underneath of the carrier rails 32 and thus the ring members 14 are in a fully closed position.
  • the ledge member 40 comes into contact with the underneath of the carrier rails 32 and causes slight upward movement of the carrier rails 32 (but does not cause the carrier rails to pivot upwards).
  • the opening/locking mechanism 20 is provided with a third ledge member 42 in order to close the ring members 14 from either the open and unlocked position directly to the closed and locked position, or from the open and unlocked position to the closed and unlocked position.
  • the third ledge member 42 has outer projections 44 which engage the upper surface of the carrier rails 32 to force the rails to move downwards and pivot downwards.
  • a ring binder 50 is shown which is similar in concept to the binder 10 shown in Figures 1 to 5.
  • the main difference between the two ring binders is the construction of the opening/locking mechanism 20.
  • the opening mechanism 20 of the ring binder 50 shown in Figures 6 to 10 is pivotally supported on each end of the upper rigid structure 24 and is in engagement with each end of the pivotable lower structure 30 in order to position fixedly the opening mechanism 20 between the upper and lower structures.
  • a projection 52 (see Figures 9 and 10) on each side of the opening mechanism 20 is provided which is internally enclosed by the squashed end 37 (see dotted line in Figure 9) of each overlapping side 26 of the upper structure 24 while the projections 52 are externally placed at the outer side ends 39 of the carrier rails 32 in order to engage and fixedly position the projection 52 between the lower structure 30 and the upper structure 24.
  • the opening mechanism 20 is supported between the upper and lower structure to allow pivotal movement, but otherwise is fixedly mounted therebetween (ie no lateral movement etc).
  • the whole outer ends of the upper structure 24 are substantially unobstructed with downwardly depending flaps and the like.
  • the opening mechanism 20 to assemble the opening mechanism 20 to the ring binder, one only needs to place the opening mechanism 20 directly between the upper and lower structures 24 and 30, and then to crimp (ie pinch) together the overlapping end 37 of each side 26 of the upper structure. Since the outer ends of the upper structure 24 are substantially unobstructed with downwardly depending flaps and the like, the additional advantage of saving of material is achieved. In this respect, between 2 and 4% saving of material over known arrangements can be obtained.
  • the ring binder 50 has two closed positions (see Figures 6 and 7) and an open position (see Figure 8) similar to the ring binder 10 of Figure 1.
  • first engagement means in the form of a ledge 54 for cooperating with the underneath surface of the pivotable carrier rails 32
  • second engagement means also in the form of a ledge member 56 which is engageable with the upper surface of the pivotable carrier rails 32.
  • the ledge 54 engages the underneath of the carrier rails 32 at the closed position shown in Figure 7, and further movement of the lever 20 outwardly causes the ledge 54 to push up the underneath of the carrier rails to the open position shown in Figure 8. Thereafter when the opening mechanism is pulled inwardly to close the rings, the ledge 56 acts on the top of the carrier rails 32 in the open position shown in Figure 8 to push down the carrier rails 32 to the closed position shown in either Figure 6 or 7.
  • the ring binder 50 also has a locked position (see Figure 6) and two unlocked positions (see Figures 7 and 8), similar to the binder 10 shown in Figure 1.
  • the locking mechanism 20 is in a basically "b" shaped section where the top of a base portion 58 of the "b" shaped section is provided with a couple of flat surfaces 60 which act against the underneath of the upper structure 24.
  • this top surface 60 is disengaged from the underneath of the upper structure 24; however, once the locking member 20 is moved inwardly, this upper surface 60 comes into contact with the upper structure 24, preferably at the same time as the ledge 56 on the base portion 58 comes into contact with the top of the carrier rails 32.
  • a front wall 62 of the base portion 58 of the opening mechanism is over centre by an angle ⁇ , and inwardly directed for instance towards the axis 64 of the fastening means 34 in order to give inherent resistance to unlocking of the opening mechanisms 20.
  • the mechanism 20 will resist this when in their locked position because such forces will tend to force the front wall 62 to move to the right in the sense viewed in Figures 6, so wedging/jamming the front wall 62 of the base portion 58 between the upper structure 24 and the carrier rails 32 and so tending to keep the mechanisms 20 in their locked positions.
  • the distance along the front wall 62 between the flat surface 60 and the bottom of ledge 56 is slightly greater than the distance between the upper structure 24 and the lower carrier rails 32 when depressed downwards, such that a locking and wedging/jamming effect is achieved.
  • the upper end 62 a of the wall 62 is smoothly rounded so that, when the mechanism 20 is moved it does not cut or scar the underside of the base member 12.
  • the advantage of locking the ring binders 10 and 50 is that the binders are easy to open and the papers within the ring binder will not become dislodged from the ring members, whilst the advantage of supporting the opening mechanism externally of the lower structure and internally of the upper structure is that the ring binder can be assembled by a machine.
