Definitions

  • Our invention has for an object to provide an improved binding including pivotal open links constituted by a plate carrying twin pins.
  • Each open link is provided with two preferably crookshaped or curved pins at the ends of a plate, the crooks or curves formed by said pins lying in parallel planes which are oblique with reference to the longitudinal axis of the plate.
  • the planes defined by the crook-shaped pins are substantially perpendicular to the axis of the binding and said pins then form guides for the continuous insertion of the sheets to be bound, one series of perforations in said sheets disengaging the corresponding pins of a series of links only when the other pins of said series. of links have engaged another series of perforations arranged in staggered relationship with reference to the perforations of the second series.
  • the opening of the binding and consequently the release of the sheets carried by said binding are effected by a pivotal movement of the whole link system forming the binding whereby, at the end of the pivotal movement, the crook-shaped pins are no longer substantially perpendicular to the axis of the binding and an uninterrupted free space provided between the cooperating ends of the two series of pins corresponding to the two series of perforations so that the sheets may be taken out of the binding through said free space.
  • Our invention covens in particular a very simple and advantageous embodiment of a binding exhibiting the above features and including a strip of somewhat elastic material preferably such as extruded plastic material, said strip being folded along a longitudinal line of fold, and the edge of one of the folded flaps thus formed being provided at predetermined uniform intervals with notches w-hile perforations are provided in accurate registry with said notches in the other flap which is secured to the body of the binding.
  • a perforated strip fitted over those pins of the open links which are not inserted in the notches is adapted to control, through a translational movement, the pivotal movement of said links around the first mentioned pins inserted in the notches.
  • our invention allows furthermore obtaining an accurate centering of the ends of the pins with reference to the perforations to be engaged by them, said centering being effective to improve the smooth shifting of the sheets from one series of pins of a succession of links onto the other series.
  • the outline of the pins is such that, when they are viewed endwise, their projection on a common plane parallel with their planes does not form a closed annulus, but a loop constituted by two free strands crossing each other.
  • FIG. 1 is a diagrammatic showing of the operation of our improved binding
  • FIGS. 2 and 3 illustrate diagrammatically the operation of different embodiments of our invention
  • FIG. 4 is a perspective view of a complete binding assembly with the links in their closed position
  • FIG. 5 is a perspective view of the same complete binding as FIG. 4, showing the links in their open position
  • FIG. 6 is a perspective view of part of a folded yielding strip
  • FIG. 7 illustrates a detail associated with said strip
  • FIG. 8 is a partial sectional view showing a pin-carrying plate fitted between the flaps of a folded yielding strip
  • FIG. 9 is a diagrammatic plan View, as seen from above of our improved binding.
  • FIG. 10 is an elevational end View of an open link of a conventional type
  • FIGS. 11 and 12 are elevational end views of open links incorporated with our improved binding.
  • the link forming part of our improved binding is constituted by an open member, of metal or any other suitable material.
  • the links when in the position illustrated at A the sheets F during their shifting by guiding them continuously over the open sections of the links.
  • the continuity of the guidance is interrupted and the removal or the insertion of one or more sheets F through the opening between the links becomes thus possible.
  • the actual binding includes at least two rings so that the sheets may be held during their shifting by as least two perforations.
  • FIG. 2 illustrates an embodiment with alternating pins, wherein the ends of the pins of each link overlap as shown by the area 2' while the shape of the pins at f facilitates the shifting of the sheets from one pin of a link onto the other.
  • the spacing 12 between successive links may be selected as desired.
  • FIG. 3 shows the pins in open position.
  • Suitable actuation means (not shown in FIGS. 1-3) are provided for pivotally moving the links about points AB and CD considered pairwise.
  • the opening of the binding is obtained by imparting to such means a translational movement which is oblique with reference to the axis of the binding, which leads to a simultaneous pivotal movement of all the links.
  • FIGS. 4 to 8 illustrate in detail a preferred embodiment of our invention.
  • a strip 2 of a slightly elastic material provided with a lateral flap 3 formed by longitudinally folding the strip 2.
  • the edge of said flap 3 is provided at uniform intervals with notches 4 the bottom of which opens into a broader circular opening 4a (FIG. 6).
  • the body of the strip 2 is provided with perforations 5 registering with the corresponding circular openings 4a of the notches 4 and in the section which is not covered by the folded flap 3, one or more ports 6 is provided for a purpose which will be disclosed hereinafter.
  • Each open link includes, as already mentioned, a plate 7 rigid with two crook-shaped or curved pins 8 and 9.
  • the plate 7 is provided on its upper surface with a V- shaped step 1%), the function of which will be disclosed hereinafter.
  • the pin 8 projects slightly at 8a beyond the lower surface of the place '7 as shown in FIG. 8.
  • the number of open links is equal to the number of notches 4.
  • Other embodimerits may include a number of links which is smaller than the number of notches.
  • the plate of each link is fitted between the body of the strip 2 and the flap 3, the lower end of each of the pins 8 extending through the circular opening 4a of a corresponding notch 4 while the lower projection 8a of the pin is engaged in corresponding perforation 5 (FIG. 8).
  • each link is rigidly held by the yielding strip 2 and is adapted to pivot around the vertical axis of the lower end of its pin 8.
  • each fiat lateral surface of the V-shaped step 19 on the plate of each link abuts, at the end of the pivotal movement of the links in the corresponding direction, against the edge of the flap 3.
  • the lateral surfaces of the steps facing in one direction abut against the flap 3 and the other lateral surfaces abut against the flap in the configuration in FIG. 5.
  • This arrangement allows limiting between two suitably selected extreme positions, the amplitude of the pivotal movement of the links.
  • the port or ports dformed in the strip 2 can cooperate with a stud on the lower surface of the corresponding plate or plates (FIG. 7) and this arrangement ensures a locking of the binding in said closed position.
  • the elasticity of the strip 2 allows releasing without any difiiculty said stud or studs whenever the binding is to be released and opened.
  • the locking studs are constituted by lower projecting sections 9a of the pins 9 (FIG. 8).
  • the number of ports 6 may be equal to the number of links.
  • a further object of our invention consists in the execution of links the outline of which promotes the passage of the sheets from one pin of each link onto the other pin.
  • FIG. 9 shows diagrammatically in plan view the binding of FIG. 4 in closed position with the two series of pins 8 and 9. It is apparent that each pin in each series or row registers transversely with a point of the gap separating two pins of the other row. Furthermore, the pins of both series overlap transversely of the carrier membar as shown at c. A'perforated sheet transferred from one row to the other is'held, while it lies in this overlapping area, by the pins of both series.
  • the shape of the pins 8a, 9a is such that when viewed endwise as illustrated in FIG. 10, the two rows of pins form in elevational view, a perfectly closedannulus, the ends of the pins of each row registering accurately with the outline defined by the pins of the other row.
  • the advantage of said arrangement resides in that when a sheet is shifted over the overlapping area 0, those perforations which are not engaged by the pins feeding the sheets and which are about to engage the pins which are to receive them enter, by reason of the deformation produced by the tractional stress exerted on the sheet, a position which is slightly above the location of the perforations still engaged by the feeding pins and held fast by the latter. It is apparent that the ends of the receiving pins lying slightly outside the outline of the feeding pins are thus correctly positioned and ready to engage the corresponding free perforations, as may be provided possibly by a preliminary sliding along the sloping sheet before engagement of the said pins inside the perforations.
  • a binding for loose sheets comprising a plurality of open links including each a plate, crook-shaped pins rigid with corresponding ends of the plate and extending onthe same side of the latter inparallel planes oblique withreference to the axis of the plate, the incurv-ed ends of the pins facing inwardly of the plate, and means interconnecting said links and adapted to make the latter pivot simultaneously each around a pivotal axis registering with the axis of the end of one predetermined pin on the plate to shift the plates between an operative angular position for which the pins cross a' predeterminedlongitudinal line registering with the medial position of a sheet in the binding and an inoperative angular position for which the pins lie to either side of said medial position.
