4 Claims. 1

My invention relates to filing means for holding loose leaves.

An important object of the invention is to provide a filing device which will securely retain the loose leaves in place and which will permit of the ready and convenient insertion and removal of the leaves, and which is adjustable to contract or enlarge the loops, to permit of the proper turning of the leaves.

A further object of the invention is to provide a loose leaf holding device, the engaging parts of which have proper frictional engagement to prevent displacement, but so constructed that they may be readily assembled and separated.

A further object of the invention is to improve the arrow head of the narrow strap to facilitate the folding of the arrow head.

A further object of the invention is to provide means for forcing the free end of the wide strap against the edge of the stack of leaves.

A further object of the invention is to provide means for mounting the filing device upon or within a binder and which will permit of the opening of either cover of the binder without strain upon the mounting means.

A further object of the invention is to provide filing devices of the above mentioned character which are adjustable for receiving different thicknesses of stacks of leaves.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to desi nate like parts throughout the same,

Figure l is a plan view of filing devices embodying my invention, appliedto a binder, the filing devices being in a hat position, the loops contracted, and the stack of leaves resting upon the back cover of the binder,

Figure 2 is a similar view with a stack of leaves arranged upon the front cover, the attaching hinges being vertical, and the loops contracted,

Figure 3 is a plan view of a narrow strap included in the filing device,

Figure 4 is a similar view of the body portion of the filing device,

Figure 5 is an enlarged plan view of one of the filing devices in the position shown in Figure 1,

Figure 6 is a longitudinal section taken on line 6-6 of Figure 5,

Figure 7 is a plan view of one of the filing devices in the position shown in Figure 2,

Figure 8 is a longitudinal section taken on line 8-8 of Figure 7,

Figure 9 is an enlarged plan view of one of the filing devices, showing the body portion pulled to the open position, to expand the loop,

Figure 10 is a longitudinal section taken on the line IBIG of Figure 9, showing the stack of leaves arranged over the back cover.

Figure 11 is a similar view, showing parts of the stacks of leaves arranged over the front and back covers.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral In designates a loose leaf binder including front and back covers I l, secured together by a flexible back i 2. These parts are preferably formed of plastics material, which is flexible.

Arranged upon the inner face of the back it are fiexible hinges is, preferably formed of plastics material. These hinges are secured to the back l2 by electric welding, as indicated at 12, although the hinges may be attached to the back by cement, staples, rivets or the like. It is thus seen that the hinges it have corresponding ends attached to the back l2, while their opposite ends M are free. I have shown three hinges, and three filing devices, but of course this number may be varied.

Each filing device comprises an elongated body portion l 5, which is preferably formed of plastics material. This body portion is flexible and slightly elastic. The body portion is provided at its attaching end and transverse center with a small opening it, and at its opposite free end, with a pull tongue ii. The body portion 15 has a wide strap is stamped therefrom, one end of which is integral with the body portion. The free end of the Wide strap is is provided with a small opening i9, and longitudinally spaced large openings 20 are formed in the strap i3 and the body portion l5 and all of these openings are arranged at the transverse center of the body portion and constitute a longitudinal group. The small openings It and i9 are preferably of the same size and smaller than the openings 28, and the openings 2% are preferably of the same size. Co-acting with the body portion i5 is a flexible narrow strap 2!, formed of plastics material. This narrow strap is considerably longer than the body portion iii. The narrow strap is slightly longitudinally elastic and preferably has a higher degree of elasticity than the body portion. As is well known, there are plastics materials upon the market which are slightly elastic and are in general use in making belts, suspenders or the like, and this is the plastics material which I use. At one end, the narrow strap 2| has a head 22 provided with a small opening 23. At its opposite end the narrow strap 21 has an arrowhead 24, formed with inclined shoulders '2 5. The arrowhead has a longitudinal slit 26 whereby the arrowhead may be more easily folded transversely upon its longitudinal axis to be passed through the openings.

In assembling, starting with the hinges is being attached to the back i2, the head 22 of the narrow strap 2| is arranged next to the hinge adjacent to its free end, and the attaching end of the body portion 25 is placed upon the head 22, the opening 23 registering with the opening it for receiving a metallic attaching element 2'1, such as a brad or rivet. The attaching element passes through an opening 28 in the hinge. It is thus seen that the body portion and narrow strap are arranged in superposed relation and secured to the inner face of the hinge, which is remote from the back. The arrowhead is folded transversely upon the longitudinal slit and is passed through the small opening l9 in the free end of the wide strap 13 and this brings the narrow strap 2! into the opening. Since the opening is is considerably smaller in diameter than the width of the narrow strap, these parts have considerable frictional engagement, may be adjusted but there is little tendency for the wide strap to slip upon the narrow strap. The narrow strap, Figure 6, is now passed through the openings 23 in the stack of loose leaves 36 and through the openings 3! in the binder leaves 32; the narrow strap 21 is now passed through selected openings 20, and the narrow strap is pulled to the right, Figure 6, and slips with relation to the body portion Hi. This contracts the loop i2 formed by the wide strap l8 and narrow strap 2|, and this loop receives the portion iii of the loose leaves. The narrow strap has its arrowhead extending beyond the pull tongue 1?. The free end of the wide strap is in close relation to the stack of loose leaves as it is drawn into this relation by the pull upon the narrow strap, and substantially retains this position. The openings 29 are circular to facilitate the passing of the arrowhead through such openings, and these openings have a diameter slightly smaller than the width of the narrow strap, to afford proper frictional engagement with the narrow strap so that the wide and narrow straps will not have improper sliding engagement to expand the loop i8-. With the parts thus arranged, the front cover may be opened, Figure 6, or the back cover opened, Figure 8, and the loose leaves will lie fiat. When it is desired to turn the leaves, the operator engages the pull tongue 11 and pulls the body portion to the left, Figure 10, while pressing down upon the loose leaves. The narrow strap 2i slides with respect to the wide strap I8, expanding the loop :8, Figure 10. The leaves may be readily turned, and will lie flat upon the front and back covers, Figure 11. When the folder is to be closed, all loose leaves are returned to the position over the back cover and the narrow strap is pulled and swung to the right, contracting the loop l8, and returning the parts to the adjusted position, Figure 6.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
