LOOSE-LEAF BINDER Filed Feb. 1a, 1946 2 Sheets-Sheet 2 Patented Apr. 10, 195i UNITED STATES PATENT oEF cE Claims.

The present invention relates to a loose leaf binder and especially to a novel binder construction comprising a pair of separable sections for receiving and retaining loose sheets, charts or pages, and in which these sheets Or the like may be quickly inserted or removed by a simple manipulation.

Among the objects of the present invention is to provide a novel loose leaf binder including a cover provided with spaced, staggered slots for receiving complementary sections of the binder. In the novel embodiment, these sections do not extend beyond the edges of the cover or loose leaf sheets and the latter do not offset when the cover or pad is open.

A further object of the present invention is to provide a binder including a pair of complemem tary sections, each provided with a parallel backing strip and spaced arcuate-shaped segments or projections forming closed loops or binder rings when the secticns are assembled for retaining a plurality of sheets, charts, pages or the like.

Another object of the present invention is to provide a novel binder comprising a pair of sections which maybe quickly assembled or disassembled by a simple, longitudinal movement, and requires no pivotal connection or spring-actuated mounting for opening or closing the binder. Furthermore, the present novel binder requires no special equipment to assemble it in its cover, and when assembled, the parts or sections automatically and securely interlock and prevent accidental or unintentional removal of the attached sheets.

Further objects are to provide a construction of maximum simplicity, efficiency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the construction, combination and arrangement of parts illustrated in the accompanying drawings, and while there is shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change, and comprehends other details, arrangements of parts, features and constructions without departing from the spirit of the invention.

Referring more particularly to the drawings and to the novel illustrative embodiment therein shown, the present invention comprises a novel binder I sembled is adapted to receive and retain a plurality of loose sheets, charts or pages 3 adapted to comprise a pad, manual, hook or the like. The binder includes a pair of complementary sections 4 formed of metal, plastic or other material suitable for the purpose, with each section consisting of a backing strip 5 provided with a plurality of spaced, arcuate or crescent-shaped arms or members 6, which when the binder is assembled form a plurality of spaced loops for receiving and retaining one or more sheets, pages, charts or the like 3.

The backing strips 5 project radially inward when the binder is closed and extend in parallel, abutting relation, the sections being so constructed and arranged that the sheets, pages, charts or the like 3 lie fiat against the cover or support when the pad or book is in open position, as shown more clearly in Fig. 1. Each backing strip is provided at one end with an out' sections when the tongue or lip I of one section engages over the end H! of the other section.

When these sections are moved endwise into inin closed, assembled relation.

having a cover 2, which when as-- The cover 2 is preferably formed of a single or integral sheet of some suitable backing material having two sets of spaced slots or elongatedopenings II, II and l2, [2, with the slots H, H offset or staggered with respect to slots l2, 12. These slots are longer than the width of the arcuate or crescent-shaped members or arms 6 in an amount suflicient to permit the complementary sections 4 of the binder, with the arms or members 6 of one section interlaced or projecting through the slots H, H and the other through the slots l2, 12, to be shifted laterally of the cover in their assembly or disassembly. Thus when the sections are disassembled, the upper section 4 is moved to the left when viewed in Figs. 1, 2 and 4 in which the arcuate-shaped arms or projections E are moved to the left end of the slots H, H, while the lower section 4 is moved to the right with its arms or projections 6 moved to the right in the slots l2, 12.

Upon the sections 5 being moved into parallel position and then moved longitudinally relative to each other, the opposite ends H) of the backing strips 5 are so disposed as to seat under and interlock with the rearwardly projecting tongues or lips I at the other ends of the backin strips 5. In this assembled position, the complementary arcuate projections 6 form closed loops or binder rings securely retaining any desired number of sheets, pages, charts or the like. This operation is clearly shown in Fig. l and also in Figs. 8 and 9. In these latter views, the comple mentary, abutting ends of the arcuate projections 6 are tapered as in the preceding figures, but one is formed with a notch 13 and the other with a detent M for interlocking engagement. Also one of the backing strips 5 may be provided with one or more hooks l4 intermediate its length and the other with one or more slots or notches l6 for receiving the hooks to lock these strips together. This locking means is especially useful where the binder strips may be relatively long, although such locking feature may also be employed at the ends of the strips.

In Fig. is shown an alternate formof cover I! for receiving the complementary sections 4 of the binder I, and in which form the cover is folded upon itself to provide a pair of spaced and inwardly extending projections l8 each provided with a set of elongated slots II or l2, the slots being offset or staggered in the same manner and relation as shown clearly in Fig. 2 of the drawings. In this form of the invention, the complete binder l is enclosed within the cover and provides a novel assembly.

The present novel construction of binder requires no special equipment for assembly and permits the quick insertion or removal of one or more sheets from any position within the binder by separating the sections in the manner outlined above. Furthermore, the sections forming the binder are not pivotally or otherwise connected so that either section may be readily removed and replaced should the occasion require. Although the present binder is shown as associated with a cover, it will be readily appreciated that the novel construction may be employed as a complete unit Without the cover.

Having thus disclosed the invention, I claim:

1. A loose leaf binder comprising a cover formed of a single sheet provided with a front and back, a pair of complementary sections each provided with a backing member and spaced arcuate projections, spaced slots provided in the back and front of the cover loosely receiving the arcuate projections, interengaging means on the backing members for retaining the sections assembled when the backing members are placed in parallel position and moved longitudinally and relative to each other into abutting and coinciding relation, said slots being staggered in the front and back of the cover and of such length as to permit the sections to be quickly moved relative to each other and laterally of the cover and into and out of assembly, and when assembled, the cover is held firmly against relative movement with respect to the sections.

2. A loose leaf binder having a cover formed with a back and front, a pair of complementary and separate sections each provided with a backing member and spaced arcuate projections, spaced elongated slots provided in the back and front of the cover for receiving the arcuate projections and of substantially greater length than the width of the projections permitting the projections to be moved upon longitudinal, relative movement of the backing members into and out of assembled relation, and means on the backing members for locking these members together when they are located in parallel position and moved longitudinally and relative to each other into coinciding relation and disengaging them when these members are moved out of such position, said slots being disposed in staggered relation and of such length as to permit the sections and their arcuate projections to be moved laterally of the cover suflicient to permit ready assembly or disassembly of these sections.
