Definitions

  • ABSTRACT A strip of material comprising slots and fastening means is designed to be folded and assembled with a ring of a loose-leaf binder in such a way as to prevent the unintentional opening of the ring and to hold down the loose-leaf pages.
  • Loose-leaf binders require both a means of keeping the rings from opening unintentionally and a means of holding the pages together.
  • the known holding means do not prevent the rings from opening unintentionally, as very often happens during transportation, or when the binders are pushed into upright file containers.
  • the securing device for a loose-leaf binder having rings each formed of two ring-halves, comprises a strip of material having three fold-lines disposed at right angles to the longitudinal axis of the strip, two elongated slots, two resilient lobes at one end of the strip, and a hole disposed at the base of the lobes, wherein the fold-lines are so disposed that the strip can be folded into four sections by bending it at a 90 angle in one direction along the first two fold-lines and folding it back by 180 in the opposite direction along the third foldline so that the first, third, and fourth sections thus formed then lie in substantially parallel planes, the slots are then situated in the first and third sections, lie upon one another, and are adapted to cooperate with a ring, the width of the slots being greater than the thickness of the ring, the slot in the first section being longer and the slot in the third section being shorter than the diameter of the ring, the free end of the fourth section is adapted to form a
  • FIG. 1 is a top plan view of the device before folding
  • FIG. 2 is a corresponding side elevation
  • FIG. 3 is a side elevation of the securing device in use
  • FIG. 4 is a corresponding top plan view.
  • the loose-leaf securing device consists of a strip 1 of polypropylene which is divided by fold-lines 2-4, running at right angles to its longitudinal axis, into four sections 5-8, the third of which (7) is the longest.
  • the fold-lines 2-4 are formed by suitable cross-sectional weakenings which are so disposed that, as viewed in FIG. 2, the strip 1 can be folded downwards along the foldlines 2 and 3, but upwards about the fold-line 2.
  • the slots 9 and 10 are of different lengths, that of the slot 9 being greater and that of the slot 10 being less than the diameter of a loose-leaf binder ring 11.
  • the free end of the section 8 takes the form of a fastening head and comprises two outwardly extending end lobes 12 which define between them a hole 13 for the passage of one of the two ring-halves 11a of the ring 11.
  • the lobes 12 also comprise on their facing edges two inwardly projecting holding portions 12a, the space between which is less than the thickness of a ring-half 11a.
  • the securing device is used with a loose-leaf binder of the type having a ring-supporting strip 15 attached to the inside of the back cover, adjacent to the spine.
  • the securing device is assembled with a ring 11 of such a binder in the following manner: first the slot 9 of the strip 1 is pushed down over the closed ring 11 of the as yet empty binder.
  • a further fold-line 14 enables the section 5 to fit against the slightly cambered ringsupporting strip 15.
  • a bevel 9a in the outer edge of the slot 9 serves to facilitate gripping behind the respective ring-half 11a and thus helps to keep the unfolded strip 1 from falling off the ring 11.
  • the ring 11 may now be opened, loose-leaf pages 16 inserted, and the ring 11 re-closed.
  • the strip 1 is then bent at a angle along each of the fold-lines 2 and 3, and the section 7 is pushed over the closed ring 11 as far as the length of the slot 10 allows, with the ring 11 passing partially through the slot 10.
  • the end section 8 is folded back by in the opposite direction, and the two end lobes 12 are pressed down on each side of the projecting portion of the ring 11 so that one of the ring-halves 11a passes into the hole 13, while the two holding portions 12a of the lobes l2 lie beneath the uppermost portion of the ring 1 1 and thus hold the strip 1 securely in place.
  • a securing device for a loose-leaf binder having rings each formed of two ring-halves comprising a strip of material having three fold-lines disposed at right angles to the longitudinal axis of said strip, two elongated slots, two resilient lobes at one end of said strip, and a hole disposed at the base of said lobes, wherein said fold-lines are so disposed that said strip can be folded into four sections by bending it at a 90 angle in one direction about the first two of said fold-lines and folding it back by 180 in the opposite direction along the third of said fold-lines so that the first, third and fourth of said sections thus formed then lie in substantially parallel planes, said slots are then situated in said first and third sections, lie upon one another, and are adapted to cooperate with a said ring, the slot in said first section extends into said second section, the width of said slots being greater than the thickness of said ring, said slot in said first and second sections
