This invention relates f to a binderv forf securely holdinga ller unit fwhich may be readily removed and replaced by a similar` filler unit when Hits period of usefulness is ended.

The binder is particularly applicable for use with filler units comprising' apluralitypf 1checksV and check stubs wherein the stubs are permanently boundtogetherv by 'a `wire binding, but may be used with fillers of any kind, such as catalog pages. neergang ,becomes .obsolete or useless before the binder wears out. It may also be used alternately with different sections of a master catalog where the use of the entire catalog at one time is not necessary.

It is an object of this invention to provide a binder with means for quickly and easily securing a wire-bound filler thereto. Another object is to provide means that will hold the contents securely and may be readily released to permit removal of the contents whenever desired. Another object is to provide a sturdy binder that may be used indefinitely with a series of ller units.

Gther objects and-advantages of my invention will become apparent upon reading the following description, taken in conjunction with the accompanying drawing, illustrating a preferred structural embodiment, in Which:

Figure 1 is a perspective View of a binder embodying the invention;

Figure 2 is an enlarged fragmentary perspective view showing the filler unit removed from the binder;

Figure 3 s a perspective view of the retaining rod;

Figure 4 is a fragmentary perspective view of the binder with the filler secured therein by the retaining rod; and

Figure 5 is a cross sectional view, taken along the line 5-5 of Figure 4.

In the drawings, the reference numeral 2 indicates a binder back to opposite edges of which cover

members

3 and 4 are hinged in any conventional manner. The binder back includes a metal plate 5, and its inner surface is covered by a suitable lining member 6. Adjacent one end of the binder back a pair of projections or lips 1 is struck up from the metal plate 5. These lips project through the lining material and eX- tend upwardly at substantially right angles to the binder back. The lips 'I are preferably integral with the metal plate 5, but they may be formed separately and secured thereto by welding or in any other suitable manner. Although it is preferred to use a pair oi lips 1, a single projection of anysuitable shape may be substituted therefor. I

r Aplurality of straps is formed in the metal .plate 5 by slitting the metal along pairs of parallel lines that are arranged angularlyrela- )tive to vthe .opposite ends of the metal plate. -Theifmetal between each pair of Islits is struck eupwardly to form. the -straps which project athrough aperturesprovided in the lining material. Thestrapsare shown as .being closed 4at both ends, but maybe openat one end if desired.

Although the straps are preferably integral with the metal plate, they may be formed separately, either individually or as a group, and then secured to the metal plate by welding or in any other suitable manner.

vThe filler unit for which the binder is designed comprises a helical wire coil 9 threaded through a row of evenly spaced apertures provided adjacent one edge of a plurality of sheets IG. The straps 8 are aligned longitudinally of the back member and are spaced so as to have each strap fit between two adjacent convolutions of the coil. When the helical wire coil is pressed over the straps 8 into Contact with the back member the longitudinal axis of the helical coil is parallel to the longitudinal axis of the back member. The edges of the straps extend parallel to the convolutions of the coil, and each strap is substantially as wide as the distance between adjacent convolutions of the coil. The snug engagement between each strap and the two adjacent convolutions of the helical coil prevents longitudinal movement of the coil relative to the back member.

After the filler unit is properly positioned relative to the back member, a retaining rod ll is inserted through the helical wire coil in a longitudinal direction so that it is positioned on top of the inner surface of the wire at its lowermost point. The rod Il is threaded under each strap 8, thereby cooperating with the straps to prevent accidental vertical or transverse displacement of the coil relative to the back member. The retaining rod is preferably made of a length of Wire, but may be made of any suitable material. One end of the retaining rod is curled to form a loop I2 which encircles the lips l. The lips preferably project as far above the metal plate 5 as the straps 8 so that the loop l2 remains in engagement with the lips 'I even when the binder is held with its back above the ller. The engagement of the loop l2 with lips 'I prevents accidental longitudinal displacement of the retaining rod relative to the back member.

When it is desired to remove a ller unit from the binder it is necessary only to lift the loop l2 upwardly out of engagement with the lips 1, and then slide the retaining rod longitudinally out of engagement with the straps 8. The steps of the above described method are reversed to secure a ller unit in the binder.

Although I have described a preferred embodiment of my invention in considerable detail, it will be understood that the description is intended to be illustrative, rather than restrictive, as many details may be Inodied or changed without departing from the spirit or scope of the invention. Accordingly, I do not intend to be restricted to the exact structure disclosed, except as limited by the appended claims.

I claim:

1. In a binder, a back member having a metal plate, a plurality of parallel straps projecting upwardly from said metal, said straps extending angularly relative to the ends of said back member, a projection extending upwardly from said metal plate adjacent one end thereof a distance substantially equal to the height of said straps, and a retaining rod extending between said straps and said back member, said retaining rod detachably engaging said projection in a plane substantially parallel to the plane of said back member to prevent accidental longitudinal displacement of said rod relative to said back member, said rod 4 being movable upwardly to disengage it from said projection.

2. In a binder, a back member having a metal plate, a plurality of parallel straps projecting upwardly from said metal, said straps extending angularly relative to the ends of said back member, a projection extending upwardly from said metal plate adjacent one end thereof, and a retaining rod extending between said straps and said back member, said retaining rod having at one end a loop detachably encircling said projection in a plane substantially parallel to the plane of said back member to prevent accidental longitudinal displacement of said retaining rod relative to said back member, said loop being movable upwardly to disengage it from said projection.

GEORGE J. RUNDBLAD.
