REFILLABLE LOOSE-LEAF BINDER Filed Aug. 11, 1944 IN VEN TOR. k7-Mw? 5900/1* BY MKM.
Patented Mar. 8, 1949 UNITED STATES PATENT OFFICE REFILLABLE LGOSE-LEAF BINDER Arthur F. Brook, Poughkeepsie, N. Y.
Application August 11, 1944i, Serial No. 549,051
1 Claim. 1
The invention herein disclosed relates to binders of the ring type, and objects of the invention are to provide an inexpensive form of binder which will have desirable characteristics of both the rell and the loose leaf forms of binders.
Further special objects of the invention are to accomplish the above without adding to the bulk or weight of the binder or, in the case of a flexible book structure, without destroying or impairing the flexible character oi the binder.
Other desirable objects and the novel features by which the purposes of the invention are attained are set forth or will appear in the course of the following specification.
The drawing accompanying and forming a part of the specification illustrates certain present practical embodiments of the invention but structure may be modified and changed as regards the present illustrations, all within the true intent and broad scope of the invention as hereinafter defined and claimed.
Fig. l in the drawing is a plan View of the cover construction fully opened in at form and showing at the top how the open rings of the binder "1^ are entered beneath the edges of the nat holding strip;
Fig. 2 is an end view of the 'attened, fully opened cover structure;
Figs. 3 and 4 are enlarged broken cross sectional views showing the binder rings engaged in the holder or cover structure;
Figs. 5 and 6 are broken plan and longitudinal sectional views, respectively, of a modified form of the holder structure.
Figs. 1 and 2 illustrate a one piece cover structure made up of flexible covers 1 and 8 connected by scored fold lines 9 with an integral back portion I8. Secured flat over the inside face oi the back is a strip of iiat, flexible material H, of slightly less width than the back. This strip is secured along its longitudinal central portion, in the illustration, simply by a pair of staples l2.
The strip Il thus secured reenforces the back without materially adding to the bulk or weight of the back and Without destroying the inherent exibility of the same. The edges of the at strip, while normally resting flat against the back as in Figs. 1 and 2, are unattached and hence free to be bent away from the back, and this characteristic is made use of in applying and attaching the binder rings to the cover structure.
In Figs. 3 and 4, a group of leaves I3 are shown threaded over the rings lll of a so-called Wire-O binder which has been left in the intermediate E formation7 with the ends oi the flexibly connected rings open and Separated 150 an extent indicated at l5 in Fig. l.. This opening, as shown in Figs. 3 and 4, is of less extent than the width of the strip H, so that the group of connected rings can be slid down over the strip with the separated, open ends of the rings passing in between the edge portions of the strip and the back.
Because of the ilattened, generally oval shape, the rings operate as wedges to bend up the side edges oi the strip. This yielding, frictional engagement of the ring ends between the edges of the strip and the back increases as the binder is slipped down over the strip, so that ordinarily no special holding means are required to prevent the binder from slipping out from between the covers. If desired, however, positive stops may be provided at one end of the holding strip after the manner 0f the outstanding lugs I6 shown at the lower end of the strip in Fig. l. These laterally projecting lugs will be engaged by the first ring of the binder to prevent further movement of the binder over the strip. The opposite end of the strip may be beveled or tapered somewhat, as indicated at Il, to facilitate easy sliding engagement of the rings over the strip.
Figs. 5 and 6 show how the holding strip may be modied by extending it and turning under the extended opposite end portions I3, i9 of the same. These stifen the end portions and may have a tendency to more securely catch and hold the rings engaged with the strip.
Refills made up with the open rings illustrated can be quickly and easily slipped into position or be removed from the covers. The yielding, irictional engagement effected by the transverse tensioning and bending of the strip serves to securely hold the rings in place and there is no possibility of the leaves coming loose with the rings so held. To remove any of the leaves the binder must be entirely removed from the cover. Then as many leaves as desired may be quickly removed from or be engaged with the rings and the latter then be slipped back into secured position. Before the rings are applied or after they have been removed, the cover can be stored in the iiat condition shown in Fig. 2, taking up practically no greater space than an ordinary one piece cover, since the only added dimension is just the single thickness of the applied securing strip. This strip may be of some readily available, inexpensive material, such as heavy paper, ber or cardboard.
What is claimed is:
A book construction comprising a back, a strip of thin, at, flexible, non-metallic, easily bendable material in the nature of cardboard secured along its longitudinal center in flat engagement over the inner face of said back and a binder of spaced, connected open rings, said rings being open to an extent less than the width of said strip and thereby adapted to enter between the edges of said strip and the back and to bend said strip transversely into yielding, gripping engagement over the spaced ends of said rings, said strip having an end portion of the same turned under, toward the back into position forming an abutment engageable by the adjoini REFERENCES CITED The following references are of record in the le of this patent:
