Definitions

  • the present invention relates to the holder of a looseleaf binder for removable paper sheets, which are punched along an edge thereof, and inserted in a plurality of.-rings which can be opened at one location along their circumference.
  • the main object of the invention lies in the provision of such a holder which is simple in structure and extremely low in manufacturing cost while being quite ellicient in operation and sturdy in use.
  • Each holder made in accordance with the invention, is formed by setting up two identical elongated plate members so that they face one another along a longitudinal edge thereof and; in reverse symmetry. That way, only one simple mold is necessary, as the plates are preferably molded of plastic material.
  • a leaf spring holds these two plates together, by pivotally engaging each plate along and near an outer edge thereof andin such a way that the meeting edges of the plate move in toggle joint manner through a dead-center position.
  • the ;paper holding rings On one side of the deadcenter position, the ;paper holding rings are in open position, whereas on the other side, they are in closed position; being urged and kept in each respective position by the driving force of the spring. .7 L- I
  • FIGS. ,1 and 2 show, in perspective view, the holder of the invention in open and closed positions, respectively.
  • FIG. 3 is a perspective view of the leaf spring used in the holder.
  • FIG. 4 is a cross-section view taken along a vertical plane between the two rings of FIG. 2.
  • FIGS. 5 and 6 are two end elevation views ofthe holder, showing the latter in closed and open positions, respectively.
  • FIG. 7 is a plan View of one of the flat members, shown sectioned so as to more particularly depict the bottom end structure of the flat member.
  • FIGS. 1 and 2 show the general outline of the holder of invention.
  • the holder is generally composed of two elongated, generally flat base members 2 and 3, held in contact along one of the longitudinal edges (FIGS. 4, 5, 6) by means of leaf spring 1.
  • the sheet holding elements themselves, are a plurality of rings, two being shown, molded in, and vertically projecting from base members 2 and 3.
  • each single flat base member 2 or 3 is provided with only half rings or prongs 4 or 5, each adapted to mate with a corresponding half ring on a mating base member.
  • Each base member 2, 3 is provided with two finger levers 10, 11, 12, 13, each being an upstanding, generally fiat, member, outwardly extending in the direction of the longitudinal meeting edge from the opposite edge.
  • base members 2, 3 are identical and can be molded with'the same mold.
  • the distance between lever 11 and its adjacent half ring 4 be shorter than the corresponding distance between lever 10 and its adjacent half ring 4; shorter by a length equal to the thickness of a finger lever.
  • the distance between levers 12 and its adjacent half ring 5 is shorter than lever 13 and its half ring 5 by a distance equal to the thickness of a finger lever.
  • the meeting edge ofeach base member is provided with atongue 14 (FIGS. 4, 6 and 7) and a groove 15, each extending on one half side only of the base, as shown in FIG. 7. This will permit, when two such base members are placed side by side in reversed symmetry with respect .to the meeting line, to'fit tongue 14 into the facing mating groove 15.
  • one free end of a half ring 4 of a base member 2 is provided with a spherical projection 4a while the end of the other half ring 4 has a spherical housing 412.
  • Projection 4a and housing 4b will meet spherical housing 5b and spherical projection 5a respectively, when coupled to a like base member 3 as shown particularly in FIG- URE 1. 'This will ensure better alignment of the two half rings and prevent lateral displacement when in closed position.
  • eachbase member (2, 3) is cut with a longitudinal re-entrant groove 7 (FIGS. 4, 5, 6 and 7) which includes an abutting surface 8, inclined towards the longitudinal meeting edge.
  • This leaf spring is a generally flat, elongated, thin bar 1,the longitudinal edges 1a and lb of which are folded inwardly towards one another. In order to increase tension in the spring, when in use, the. latter may be bent slightly upwardlylas atld, FIG, :4. As
  • edgev 10 which is the longitudinal edge of the spring (see FIG. 3).
  • Leaf-spring D is placed into position by pressing the longitudinal edges into re-entrant grooves 7 of two opposing base members 2, 3. This placing operation is helped by the fact that pivoting edge 10 is made to slide along inclined surface 6.
  • FIGS. 5 and 6 will readily show that opening of the holder (and half rings) is obtained by applying opposed finger pressure on finger levers 10, 11, 12 and 13, more particularly on inclined indented surfaces AB, A'B'.
  • the pressure will, first, overcome the downward pressure. Then, when the meeting axial line is in the aforementioned plane, the vertical spring pressure is nil. As soon as the meeting line moves above the said plane, the spring pressure vertical component is reversed and the force is directed upwardly. Upward movement of the meeting line is, however, limited and stops when the outward surface of the spring longitudinaledges 1a and and 1b as they near this condition.
  • Closing may be obtained by applying reverse pressure, either on half rings 4, 5 or on the edges of upward portions 11', 12', and 13 of finger levers 10, 11, 12, 13.
  • Perforations 9 shown on flat surface 1 of spring D serve in fixing the holder onto the back of a binding cover. 1
  • Each holder element is, preferably, a one piece plastic article, preferably a polyamide or polyester and comprises a base member (2, 3), a series of half rings (4, 5) and two finger levers (10, 11, 12, 13) one at each end of the base member.
