Definitions

  • the invention relates to binders for loose leaves, of which there are many types. While this sort of binder is much appreciated by users, its cost is still relatively high because it requires a comparatively long time to assemble the component parts.
  • Most of the existing binders include a device comprising two opposing sets of claws forming rings to receive the loose leaves, as well as mechanism for actuating at least one of the said sets of claws in order to bring their ends together or separate them as required.
  • these claws and the operating mechanism therefor have been mounted on a metallic support, which was riveted or fixed by other means to the inside face of a cover comprising two side J covers fastened together by a back portion.
  • One of the objects of the present invention is to provide a binder of the aforesaid type which avoids the necessity for mounting the claws and their operating mechanism inside the back which connects the two side covers.
  • the binder consists of two side covers connected together by a back composed of a claw support and actuating mechanism for the claws.
  • Fig. 1 is a transverse cross-sectional view of the binder, taken along the line II of Fig. 3, the claws and side covers being in open position;
  • Fig. 2 is a similar section to Fig. 1, taken along the line 2-2 of Fig. 3, the claws and side covers being in closed position;
  • Fig. 3 is a top view of the support carrying the claws and their operating mechanism, without the side covers;
  • Fig. i is a detail view on a larger scale of part of the mechanism shown in Figs. 1 and 2.
  • the binder comprises two side covers ll hingedly connected to a back portion comprising a support or strip 3 and a cover or strip at.
  • This cover dil is provided with beaks l I passing through the perforations 2 of the side covers I.
  • This cover has openings M through which the claws 5 extend.
  • the latter are mounted on two parallel axles 2i and revolve freely thereon.
  • the cover and the support each have an end wall i l, of which only one is shown in the drawings. The axial movement of each axle 2
  • Each opening li comprises a wall #5 inclined in relation to the axles 2i acting as a cam for operating the claws 5.
  • the back of the binder comprises devices for locking the cover on its support. These devices at the same time act as guiding means for the cover.
  • These guiding devices each consist of two locks fastened to the support 3 and symmetrically arranged in relation to the middle plane of the back of the binder.
  • Each lock comprises a beak 46 carried by a resilient foot til and cooperating with a flat-topped shoulder 48 whose width is limited by the surfaces is and 50 parallel with the axles 22'.
  • the top surfaces of the shoulder 68 have a length 8 greater than the length if of the beaks (Fig. 3), in order to permit the longitudinal displacement of the cover in relation to the support. Between these surfaces A8 is provided an opening 53 intended for the passage of a pair of beaks.
  • the assembling of the binder shown is performed as follows: In the first place, the side covers I are brought into engagement with the beaks l l of the cover lt. Then the claws 5 which have :11; previously been mounted on the axles 2
  • the opening and the closing of the rings of the binder back are controlled by the relative longitudinal displacement of the cover it and of the support 3, the extent of these displacements being limited by engagement of the ends of the cover 40 with the end walls 44 of the support 3.
  • Each pair of claws forming a ring is kept in closed position (Figs. 2 and 3) by a wall 56 of the opening 4
  • the cover is displaced downwards from the position shown in Fig. 3, the claws liberated from the inclined surfaces 45 are turned on their axles 2
  • the support and the claws may be formed of plastic material. It will be understood that there are many other possible embodiments of the in-- vention in addition to the one illustrated and described.
  • a loose-leaf binder comprising a back formed of inner and outer strips connected for slidable movement relatively to each other, the outer strip having straight unindented longitudinal edges, the inner strip having its longitudinal edges comprising a series of projecting beaks turned toward and contacting the said longitudinal edges of the outer strip, side covers each having a series of holes along one margin for the passage of said beaks which thereby hingedly connect the back to the side covers, opposing pairs of claws carried by said back, said inner strip having openings through which said claws extend, said openings being inclined with respect to the center line of said strip whereby longitudinal movement of said inner strip relatively to said outer strip causes each pair of claws to move toward and away from each other to permit insertion or withdrawal of loose leaves.
  • both the inner and outer strips forming the back are U-shaped in cross-section and arranged so that each strip has its longitudinal edges turned toward the longitudinal edges of the other, and the intervening parts of such strips are separated from each other to provide a space within which the bases of the claws are located.
  • a loose-leaf binder comprising a back formed of inner and outer strips slidable longitudinally relatively to each other, the inner strip only having its longitudinal edges comprising a series of projecting beaks turned toward and contacting the longitudinal edges of the outer strip, side covers each having a series of holes along one margin for the passage of said beaks which thereby hingedly connect the back to the side covers, opposing pairs of claws carried by said back and projecting through openings in the inner strip of said back, means operable by sliding one of said strips relatively to the other for moving each pair of claws toward each other to form closed leaf-retaining rings, and means operable by sliding one of said strips relatively to the other in the opposite direction for moving each pair of claws away from each other to permit insertion or withdrawal of loose leaves.
  • a loose-leaf binder as in claim 3 which in cludes means secured to the outer portion of the back extending through and bearing on the inner side of the inner strip whereby said inner and outer strips are free to slide relatively to each other while contact between said beaks on said inner strip and the edges of said outer strip is maintained.
  • a loose-leaf binder as in claim 3 which includes members secured to the outer strip of the back extending through a. series of longitudinal slots along the center line of the inner strip of the back, such members having shoulders to engage the margins of said slots to slidably hold the inner and outer strips of the back together.
