Definitions

  • This invention relates to loose leaf binders, and particularly to binders of the visible type having means for shifting the sheet retaining prongs on one side of the binder relative to those on the opposite side.
  • Figure 2 is a fragmentary perspective view of the metal structure of the binder with the sheet retaining prongs in closed position and with certain prongs broken away for clearness of illustration;
  • Figure 3 is a view similar to Figure 2 showing the sheet retaining prongs open and the prong carrying plates shifted longitudinally relative to each other;
  • Figure 4 is a view similar to Figure 2 showing the Sheet retaining prongs in the same relative angular position as in Figure 2, but with the prong carrying plates shifted longitudinally relative to each other and with one prong broken away for clearness of illustration;
  • Figure 5 is a perspective view of the binder metal With the cover plate assembled therewith;
  • Figure 6 is a top plan view of the prong carrying plates
  • Figure 7 is a detail view of one of the rollers mounted between the prong carrying plates
  • Figure 8 is a perspective detail view of a portion of the spring back.
  • Figure 9 is a view similar to Figure 2 illustrating a modified embodiment of the invention.
  • the reference numeral 2 indicates a back member having cover members 3 secured along its opposite edges. 4 having inturned fianges 5 is secured to the back member 2 in any suitable manner.
  • a pair of 55v prong carrying toggle plates E and 1 is arranged A spring back in side by side relationship with the inner longitudinal edges abutting each other and the outer longitudinal edges engaged by said inturned fianges 5
  • the inner edges of the prong carrying plates are notched, as indicated at 3, to receive a pluralty of rollers 9.
  • the rollers are each provided With a pair of heads Hi of larger diameter than the combined width of a pair of mating notches 8 to enable the prong carrying plates to act as toggle plates.
  • the heads Hi pre- 10 vent the toggle plates from shifting vertically relative to each other at their meeting edges to prevent separation of the toggle plates when they are moved angularly.
  • Each prong carrying toggle plate has a pluralty of curved sheet retaining prongs ll secured thereto in any suitable manner.
  • 2 may be impaled on the prongs in overlapping relationship with a predetermined marginal portion of each sheet exposed.
  • the inner edges of the prongs on opposite plates meet to form closed rings when'the prong carrying plates are in the position shown in Figure 2 With the inner edges of the plates below the plane of the outer edges.
  • the rings may be opened by force 25 exerted directly on the rings so that the binder may be used as a conventional ring binder.
  • each prong carrying toggle plate is recessed, as indicated at ⁇ I3, and the inner edge of each end portion is serrated to form a rack, as indicated at Hi.
  • a pinion 15 is positioned between the racks M and is provided with a handle IB for rotating the pinion to move the prong carrying toggle plates longitudinally relative to each other.
  • the pinion may be rotatably secured to the spring back in any suitable manner or may be removable.
  • the handle is secured to the pinion by means of a screw Il.
  • 8 covering the prong carrying plates 6 and 1 is provided with a pluralty of notches I!! 40 through which the sheet retaining prongs H project.
  • the notches are wide enough to permit the desired longitudinal movement of the prongs.
  • the distance the prong carrying plates can move is limited by the notches 8 engagng the rollers 9.
  • the rollers facilitate the relative longitudinal movement of the prong carrying plates by reducing the friction.
  • the prong carrying plate 6 is provided with a pair of spaced notches 2D, 2
  • the plate 1 is provided with spaced notches 23, 24 and a projecting finger 25.
  • the notches are so positioned that the notches 20 and 24 are in alinement when the sheet retaining prongs. are in closed position as shown in Figure 2.
  • and 23 are in alinement when the toggle plates are moved longitudinally relative to each other as far as possible. It vvill be noted that the prong carrying toggle plates are in the same relative angular position when either pair of notches 20, 24 or 2
  • means for causing the relative angular displacement of the prong carrying plates includes a projection 26 securedto the spring back 4 in any suitable manner.
  • the projection 26 is slightly higher than 'the surface of the inner edges of the prong carrying plates when they are in the position indicated in Figure 2. In this position the projection 26 fits into the alined notches 20, 24.
  • the fingers 22 and 25 move into engagement with the projection 26.
  • the projection 26 has a cam action and raises the inner edges of the prong carrying toggle plates by means of the fingers 22, 25 to open the rings as indicated in Figure 3.
  • the projection does not extend high enough to move the prong carrying toggle plates past their dead center. Accordingly, as the fingers 22, 25 pass the top of the projection 26 the spring action of the spring back forces the prong carrying toggle plates back to their original relative angular position.
  • prong carrying toggle plate 21 is capable of sliding longitudinally and is provided with a rack 28.
  • the other toggle plate 29- is recessed, as indicated at 30, to allow room for the pinion
  • the prong carrying plates 21 and 29 are provided with notches 3
  • are twice as long as the notches 8 to permit the same relative longitudinal movement between the plates 21 and 29 as between the plates 6 and 1. This relative movement must be equal to the distance between two adjacent apertures 32 in the binding edge of the sheets
  • the prong carrying plate 21 is provided with spaced notches 33 having a pro- ⁇ jecting finger 34 therebetween.
  • the spring back 35 is provided with a projection 36 adapted to engage the finger 34 when the prong plate 2'! moves longitudinally.
  • the prong carrying plate 29 is notched along its outer edge and the spring back is slit to provide projections 31 secured in the notches to prevent longitudinal sliding of the prong plate.
  • a pair of prong carrying plates movable longitudinally relative to each other, and means engaging said prong carrying plates during' said relative longitudinal movement to move them angularly relative to each other.
  • a spring back In a loose leaf binder, a spring back, a pair of prong carrying plates mounted in said spring back, said prong carrying plates being movable longitudinally relative to each other, and means in said spring back adapted to displace said prong carrying plates angularly relative to each other when said prong carrying plates are moved longitudinally of each other.
