Definitions

  • the object of the present invention is a holding device for the sheets of loose leaf books comprising slitted rings that are rotatably mounted in a base member and slide means for conjointly turning all the rings at one or both ends of the base member.
  • the slits of the rings can be made wide enough to permit of removing individual sheets or a greaternumber of sheets conjointly and inserting the same again respectively, and since, to this end, the individual pairs of rings turn in two opposite directions, the sheets are always guided by the integral portions of the rings, so that the apertures of the sheets are truly aligned and thus the ends of the rings are prevented from unhoo-king, the turning operation being thus facilitated and damaging of the sheets is avoided.

  • Fig. 16b is an end elevation thereof.
  • E represents the book cover for the binder to the. back of which the base mem ber R and the rotatable leaf holding rings I are fastened.
  • Each slitted ring is provided on one side with a walled recess Ia constituting a driving projection in which a ball 2 is loosely mounted.
  • the device is composed of a sheet metal cover plate 3, which holds the rings I, a sheet metal guide plate 4 for the rings, which is carried by the cover plate 3, a slide 5 below the guide plate to enclose the lower ring portions, and a base supporting plate 5 to which the whole assembly is secured.
  • the cover plate 3 is in the form of an inverted tray of a channel shaped cross section and having depending end plates projecting below the sides of the tray.
  • the sides of the cover plate are provided with bendable tongues 32) for connecting with the base supporting plate 6.
  • the slitted rings I are rotatably mounted in apertures 3a of the cover plate.
  • the cover plate 3 is inserted between the upturned side edges of the base supporting plate 6 (Fig. 8a) and secured to the latter by means of the bent over tongues 37), so as to form with this plate a. closed hollow base member.
  • the guide plate 4 (Fig. 6a) of an arcuate cross section is disposed which is provided opposite the apertures 3a with transverse grooves 4a as guideways for the slitted rings I.
  • a slide 5 (Fig. 7a) of a curved cross section and also consisting of sheet metal is arranged one end of which is formed into a handle 5?) which projects upwardly from the base member at the lower end thereof.
  • This slide is provided with guideways as grooves 5a which are, however, not transversely directed as those of the guide plate 4, but rather inclined to each other in pairs so as to form portions of oppositely inclined helices.
  • the balls 2 secured to the rings I engage, so that the rings are compelled to revolve pairwise in opposite directions, when the slide 5 is displaced.
  • the length of the slide 5 is shorter for the range of the necessary displacement than the length of the guide plate 4,
  • the base supporting plate 6 rests upon a fabric strip S pasted onto the book cover E and is secured thereto by means of staples I (Fig. 9) which are soldered laterally on the base supporting plate.
  • the rings I are so positioned that their slits are situated inside the base member, so that none of the sheets can drop out.
  • the slide 5 is pulled out of the book cover by means of the handle 5?) in the outward direction, the rings I thus being turned so that the slits are all aligned in an upper disposition as shown in Fig. 3. Then any sheets can readily be inserted or removed.
  • the slide 5 is pushed inwardly in which way the rings I revolve back until their slits are returned to the interior of the base member.
  • each slitted ring-holder I at the circumference of each slitted ring-holder I a radially projecting stud 2a is disposed.
  • the cover plate 3 is of the same construction as in the first embodiment except that for each ring I, instead of two apertures, only one aperture 3a and a slot are provided.
  • the cover plate 3 is connected to the curved base supporting plate 6 by means of tongues 32) inter-engaging with notches 6b (Fig. 13a) and the latter is provided with depending tongues 6a which are passed through slots 8a of a curved backing plate 8 and bent down thereon in the inward direction (Fig. 10). Between the base supporting plate 6 and the backing plate 8 the fabric strip S is clamped which is pasted on to the book cover E.
  • curved guide plates 4b of arcuate cross section are inserted in the transverse grooves of which the rings 5 are guided (Figs. 10 and 15, a, b, c). Underneath these plates the curved slide 5 is positioned which is provided with oblique grooves 5a that are relatively inclined in pairs and which has a handled end 3b that projects upwardly from the base member. The shank 5c of this end is guided by a recess 3d in the adjacent end plate of the cover plate 3.
  • the studs Ed on the rings I are projecting (Figs. 10 and 16a, 1)) so that in displacing the slide 5 the rings are turned in the same manner as described above for the preceding embodiment.
  • the spacings between rings are advantageously of a length which permits of inserting in the holding device sheets of various sizes of standard punching.
  • two slides may be provided, each of which serving for controlling a separate group of rings and being controlled at opposite ends of the base member.
  • a series of slitted sheet holding rings a base member accommodating said rings circumferentially revolubly about the axis of said series, said rings having projections thereon, slide means engaging said projections on said rings at portions of their circumferences interiorly of said base member, guide means on the slide means at the engaging portions of said slide means for turning said rings pairwise in opposite directions during the sliding movement of the slide means, and handle means disposed terminally on said slide means for reciprocating the same longitudinally of said axis, for turning each pair of rings in position of interchanging sheets with the slits of the rings aligning exteriorly of said base member and for reversely turning each pair into position of locking the sheets respectively, the slits of the individual pairs being positioned on opposite sides of said axis during said turning movements.
  • a holding device for the sheets of loose leaf books a series of slitted sheet holding rings, a base member accommodating said rings circumferentially revolubly about the axis of said series, with the greater portion of their circumference situated exteriorly of said member, an arcuate guide plate for said rings disposed inside said base member and having guide grooves,
  • a holding device for the sheets of loose leaf books a series of slitted sheet holding rings, a driving stud fixed circumferentially on each ring, a base member accommodating said rings circumferentially revolubly about the axis of said series, with the greater portion of their circumierence situated exteriorly of said member, an arcuate guide plate for said rings disposed inside said base member and engaging the inner circumferences of said rings by means of guide grooves extending transversely of said axis, a slide curved coaxially with said guide plate for engaging said rings radially outwardly at their smaller circumferential portion interiorly of said base member,
  • the slits of the individual pairs being positioned on opposite sides of said axis during said turning movements.
