Application June a, 1947, Serial No. 753,079

6 Claims. 1

This invention'rela'tes to improvements in'loose leaf binders or notelbookszand more particularly to an expander adapted to be included in a loose leaf doinder to maintain theleaves ina squared and centered position and protect them against crumpling .andexcessive wear, and to maintain thecoverssubstantially parallel when the binder is closed.

It is among the objects of the, invention to provide a note book or loose leaf binder: accessory, herein referred to as an expander which may be :engaged with the binder rings in the same manner ,as the filler leaves, which will maintain the filler .leaveslin -a square and centered condition relative to the binder covers, especially when the binder contains a quantity of paper materially less than its full capacity, to protect thefiller leaves against wrinkling, crumpling, excessive wear :at their edges andcorners and from pulling out at the ring holes, which will also maintain the covers in ,a substantially parallel condition so that'the binder will have a neat and attractive appearance and can be conveniently disposed on .a shelf or in a book case, and so that several binders may :be.:stacked, one upon the other, without slipping or falling, which expander is self-adjusting to different quantities of paper or thicknesses of the filler in the binder, is simple in construction, economical to manufacture, attractive in appearance and materially enhances the appearance of a loose leaf binder to which it is applied.

Other objects and advantages will become apparent from a consideration of the following description in conjunction with the accompanying drawings, wherein:

t Figure l is aplan view of an expander illustrative of the invention, in extendedcondition.

Figure 2 is a perspective view of the improved expander in ,operatively folded condition.

=Figure3 is anend view-of a conventional loose leaf binder illustrating the application of the improved expander thereto.

Figure 4 is a perspective view of a fragmentary portion of an expander illustrative of the invention showing certain modifications to the form of expander illustrated in Figure 2.

Figure 5 is an end elevation of a fragmentary portion .of a loose leaf binder showing the application thereto of the somewhatmodified form of expander illustrated in Figure 4.

With continued reference to the drawings, the conventional loose "leaf binder or note book, as illustrated in'Figure 3, has a back ll) to which is secured "a ring retaining and flocking 'device I l carrying a plurality of rings l2 which support a filler i3 and a pair of covers It hinged to the edges of the back II] to overlie respectively the stantially parallel relationship to each other and the covers then protect the leaves'of the filler and hold the filler in a centered and squared condition relative to the binder. However, when a thin 'filler, such as illustrated in Figures 31 and 5,

is used, a large amount of empty space is left between the filler and the covers, the outer or free edges of the covers come together giving the binder a somewhat wedge-shape and the ing openings or slots l9. The plates it maybe individually foldedor scored,,as indicated at leaves of the filler lack support by the covers and are excessively worn at their edges and corners and frequently have the ring holes torn out of them. The wedge shape of such a partly filled binder renders it difficult to arrange a number of binders on a shelf or in a book case and makes it almost impossible to stack a number of binders one upon the other as is frequently desirable in order that they may be conveniently carried from one place to another.

The improved expander constituting the subject matter of the present invention, adjustably fills in the empty space between a filler and the covers of a loose leaf binder or note book and maintains the filler in a squared, centered condition protecting the leaves against excessive wear and damage and maintains the covers in asubstantially parallel condition when the book or binder is closed so thata number offsuch bin-- ders may be'conveniently arranged upon a shelf l or in a book case or may be easily carried in stacked condition.

The expander comprises an elongated rectangular sheet I5 of resiliently pliable material, such as cardboard, fiber board or heavymulti-ply paper, such as conventionally used in manufacturing book or binder covers of limited flexibility, and hold the filler in a centered and squared ccnformed of the same material.

The sheet 15 is transversely folded medially of itsslength, as indicatedat ll, to provide a pair of similar, co-extensively super-imposable inner,

plates provided adjacent to the medial transverse fold ll with a plurality of elongated ring receiv- 3 20, parallel to the transverse medial fold l1 and between the fold l1 and the ring receiving openings l9 to provide between the united edges of the inner plate IS a transverse portion extendable over the ring connected edge of the edge portions of the inner plates l8, as indicated at 22 in Figure 2, may be stitched to the inner plate edge portions as indicated in dotted lines in Figure 1, or may be formed integrally with the inner plate portions and provided by reversely folding the sheet l at the outer extremities of the inner plates, as indicated at 23 in Figure 4. If desired, the folded portion 23 may be cemented, stapled or stitched to render the reverse fold permanent so that the outer plate willbe superimposed relative to the corresponding inner plate as is clearly illustrated. in Figure 2.

Adjacent the junction between each associated inner and outer plate the inner plate is provided with a pair of oppositely directed spaced apart folds 24 parallel to the joined together edges of the associated plate. Each pair of folds 24 includes between them a sheet portion 25 adjustably extendable between the associated inner and outer plates so that the associated plates may adjustably separate to fill in the space between the filler and the corresponding binder covers as is clearly shown in Figure 3, The elongated ring openings or slots I9 in the inner plates provides sufficient freedom of relative movement between the associated inner and outer plates to permit the portion 25 to assume various positions of angular adjustment between the associated plates depending upon the thickness of the particular filler l3 and the width of the binder back Ill.

If desired the adjusting movement of the fold included portions 25 may be facilitated by applying to the inner plate surface of the plate having the fold therein suitable spring elements 2'6, particularly illustrated in Figure 4, which resiliently urge the interfold portions to a position separating the associated inner and outer plates.

If desired, each outer plate may be provided adjacent the ring openings 2| with a transverse bend 21 arranged to resilientl press the ring connected end portion of the inner plate inwardly toward the filler, as particularly illustrated in Figure 5, to assist in centering the ring connected portions of the filler relative to the binder covers.

The entire device may be formed from a single piece of resiliently pliable sheet material if desired although three pieces may be used Where considered desirable to facilitate the assembling. The device is thus of extremely simple construction and may be manufactured by standard paper products manufacturing methods, merely punching and folding operations to produce the complete device.

The expander can thus be manufactured at extremely low costs and can be provided as standard equipment with conventional loose leaf binders at little or no increase in the cost of the binder.

The invention may be embodied in other specific forms Without departing from the spirit or essential characteristics thereof. The present embodiments. are, therefore, to be considered; in

requiring 4 all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims, are, therefore, intended to be embraced therein.
