(C1. 12S- 4) This invention relates to an improved 'lyleaf u2. yWhere the ring halves l and 8 pass through construction for use with `ring binders. the yleaves, the material of the yleaf is bent One object is to provide a simple, inexpensive, at an angle to the portion I9 as at 2| and finally lyleaf construction which will operate in some terminates in an offset .arcuate portion ,22, the

As the differences over the prior art inoffset substantially the cross-sectional vdiameter volve consideration of details, these will be speof the ring half 'I 0r 3. The intermediate angucically disclosed in connection with the accom- `lar portion 2l -is slightly larger than the crosspointedout. so thattthe top .edges of the holes .Il come sube Fig. 1 is an end view of aloose-leaf ring binder stantially at the .vertex .of the angle .between in open position showing how the iiyleaf strucportions .i9 .and-.2l,.whi1e\the bottom edges of ture is used; holes t6 comesubstantially at the vertex of the l5 `Fig. 2 is a view similar to Fig. l, but with the angle between portion 2i and the arcuate por- `15 binder in closed position; tion 22, see `lig.3.
Fig. 3 is a sectional elevation on line 3-3 of Referring to FigsAand 5, Ywhen the bookis Fig. 2; v closed, alternate rings abutthe top edges ofholes Fig. a is a detail sectional view on line 4- I'I and in the open position of .the book the io of Fig. 2; and remaining rings abut .the lower edges of holes .20
Fig. 5 is a sectional view on line 5 5 of Fig. 1. IB, the lower edge being the lower edge when in the drawing, the iiyleaf structure is shown `looking at Fig. 3. associated with one form of `well known ring When the book is being closed the yleaves binder, its applicability to similar forms being act as follows: the covers lift the flyleaves virst readily apparent to those skilled in the art. contactingfthemalong'flatportion i9 andcaus- 25 Thus, in Figi, the ring binder consists of covers ing the arcuate portions 22 to bearon spring l and 2 pivotally connected as. at 3 by well known plate .IfIL .As the coversI I and A2 areswung furpiano-hinge construction to the back panel therlthe .arcuate portions slide along the x spring portion 5. .Ring mechanism@ is attached to the plate .It .and the intermediate angular portions so panel portion 5 in any suitable manner,.such 2l yfollow aroundtheminghalves, bearing .either 30 as by rivets, not shown, and has ring halves 1 ontheedgesof :holes .1 I:6.or il, untiLwhen the and 3 on which a pack oi loose-leaf sheets 9 is book.is closed,asshown.inFig.2thefat1porthreaded by passing the ring halves through tions la are vertical, the ring halves bear against the binding holes in the edges of the sheets.

In this last position the space between separated for the insertion of new sheets or rethe vertical portions I9 of the flyleaves is equal moval of old by lateral tension on the ring halves to that of the maximum capacity of the binder in 'l' and t. This particular form of ring binder closed position as determined by the dimensions mechanism is well known and, thereore, no of the covers and ring mechanism, see Fig. 2. further detailed description is deemed neces- When the binder is employed with a full pack sary. or" paper as indicated in Fig. 1, the yleaves con- As shown in Figs. l to 3, there is one flyleaf tact the outermost sheets to positively support structure l5 for each cover I and 2, the flyleaves them and prevent any binding or undue wear as 4.3 being positioned between their respective covers the book is being closed; while in the closed posi- 45 and the pack of loose-leaf sheets 9. These iiytion of the binder the flyleaves assume a posileaves are mounted on the ring halves 'I and 8 tion in Which the binder capacity is not interby having the halves threaded through a series ered with and the sheets are not pinched along of holes I6 and Il punched out of the material the binding edge, so of the iiyleai, see Fig. 3. As can be seen, the Inasmuch as the holes I6 and I'I are stag- 50 holes in the series It are oliset to those of the gered and only one series is in contact with series I l, for a purpose to be explained. the ring halves at a time, the friction between As appears in Figs. 1 and 2, the flyleaves are the ring halves 'l and 8 and the flyleaves is formed with a flat portion I9 which in the open materially decreased with the result that the position of the book overlies the covers I and action is exceedingly smooth. Also, by keeping 55 Cil the bearing surfaces between the yleaves and ring halves completely within the angular surfaces 2|, the distance between the bearing surfaces formed by the edges of the holes I6 and I'I, see Figs. 4 and 5, is kept at a minimum because the angle between portion I9 and the circumferential axis of the ring halves is large and close to 90 in all positions of the flyleaves. This last allows the ilyleaves to be constructed to fit the ring halves closely so that they are not inherently sloppy in various book positions as in the case of the usual flat ilyleaf which customarily is provided with long slots to allow the desired lifting action on the paper sheets. It 1s, of course, apparent that if desired the holes I6 and I 'I can be replaced by a series of similar slots without interfering with the various positions assumed by the flyleaves.
Likewise, while I have disclosed my flyleaf a having the arcuate portion 22 which nests against theinside of the ring halves, it is to be understood that `my invention is not limited to this preferred form. The arcuate portion could be replaced by, for instance, a suitable straight portion to bear on the spring plate I during the closing of the book. The important feature here is that portion I9 may lie parallel to the covers when the book is closed, so that the capacity of thebinder is not interferred with when a full pack of loose-leaf sheets is being used, as in Fig. 2. This result is attained by having the intermediate portion which offsets portion. I9 eX- tend across the circumferential axis of the ring halves and slightly beyond the outer and inner surfaces of the rings.
Considering the foregoing, it will be clear that by using the structure described, I have attained a simple flyleaf which performs the desired function of preventing undue wear on the binding holes of the sheets when the covers are being closed, and which in addition is arranged to cooperate with the ring mechanism in a manner not to. interfere with the capacity of the binder.
I claim:
1. A flyleaf for use with a loose-leaf binder of the kind having hinged covers and a back portion with binding rings overlying the top plate of a ring mechanism mounted on the back portion, said ilyleaf consisting of a thin, stiff sheet having an intermediate portion connecting two offset portions and holes to mount the f'lyleaf on binding rings, said holes being located in said intermediate portion whereby loose-leaf sheets resting on the flyleaf and mounted on the binder rings may entirely overlap said intermediate portion, all for the purpose described.
2. The structure of claim 1 with the offset of the intermediate portion substantially equal to the cross-sectional diameter of the rings,
3. A yleaf construction for use with a looseleaf binder having covers pivoted to a back portion and binding rings overlying the top plate of a ring mechanism mounted on said back portion, said flyleaf consisting of a thin, stiff member having an intermediate portion and two 01T- set portions with holes in the intermediate portion for threading in binding rings, one of said oiset portions being at and adapted to be supported by binder covers and the other portion arcuate and adapted to ride over the top plate of the ring mechanism and then nest against the inside surfaces of the rings when the covers are moved to close the book.
4. A yleaf construction for use with a looseleaf binder having covers pivoted to a back portion and binding rings overlying the top plate of a ring mechanism mounted on said back portion, saidilyleaf consisting of a thin, stiff sheet having an intermediate portion connecting two oiset portions with holes in said intermediate portion to mount the ilyleaf on binding rings, said holes being larger in diameter than in the binding rings with the holes staggered whereby each successive hole may form a bearing for the opposite side of the ring from the preceding hole, all for the purpose described.
5. A flyleaf construction for use with a looseleaf binder having covers pivoted to a back portion and binding rings overlying the top plate of a ring mechanism mounted on said back portion, said flyleaf consisting of a thin stiff member having two end portions connected by a flat offset with holes in the offset for threading on binding rings, one of said end portions being ilat and adapted to be supported by binder covers and dimensioned to lie parallel to said covers, the other portion being arcuate and adapted to ride over the top plate of the ring mechanism and then nest against the inside surfaces of the rings with its bottom edge in contact with said top plate of the ring mechanism when the covers are fully closed.
