BINDER AND METAL USED IN SAME 2 Sheets-Sheet 2 Filed Feb. 15, 1962 ATTORNEY United States Patent 3,156,244 BINDER AND METAL USED IN SAME Robert F. Lindgren, Aurora, and Frank J. Malcik, Chicago, Ill., assignors to Wilson Jones Company, Chicago, 111., a corporation of Massachusetts Filed Feb. 15, 1962, Ser. No. 173,421 4 Claims. (Cl. 129-12) This invention relates to a binder and to a metal used in the same. The term metal is conventionally used to indicate the operating parts of the binder and, in this application, the upper and lower casings. It is not necessary for the part known as the metal to be made of metal but the term involved is conventional in the binder art.

The metal of the instant invention is particularly adapted to be utilized in post binders which are the type of binder wherein a plurality of sheets are placed upon posts which project from one-half of the mechanism and wherein the other half of the mechanism is secured to the posts.

In constructions of this type at least one of the casings of the mechanism, since it must bear considerable pressure, must be made of relatively strong material. Where such a post is made pf steel the material has suflicient strength to prevent the casing from collapsing. However, if the casing is to be made of plastic, either in whole or in part, the plastic does not have suflicient inherent strength to prevent the casing from collapsing. Since plastics have inherent superiority over steel in many respects for this type of application including ease of manufacture, appearance, durability, etc., the instant invention has been devised in order to provide a construction that would permit a casing framed with plastic material to have sufiicient inherent strength to prevent it from collapsing.

In brief, the instant invention comprises a binder metal construction including a casing and a corrugated support member within the casing. The binder metal, in the preferred modification, is framed with plastic material, preferably high impact styrene and the construction includes both an upper and a lower casing. The lower casing has a pair of spaced posts extending upwardly therefrom and the upper casing is provided with a pair of spaced holes each aligned with the corresponding post of the lower casing. Further preferred modification will be illustrated in this specification when the best mode of carrying out the instant invention is specifically illustrated hereinafter.

The invention will be further described by reference to the accompanying drawings which are made a part of this specification.

FIG. 12 is a detail plan view of the corrugated support member disposed within the upper casing of the structure of this invention.

FIG. 13 is a side detail view of the corrugated support member shown in FIG. 12.

The invention will be further described by reference to the specific form thereof which is shown in the accompanying drawings and which represents the best mode known to the inventor for taking advantage of his invention. It must be understood however that this specific form of the instant invention is for illustrative purposes and for purposes of example only. Various changes and modifications may obviously be made within the spirit and scope of this invention and would occur to those skilled in this art.

In the specific embodiment shown, a binder 11 bears a metal 12 which is formed with an upper casing 13 and a lower casing 14. Upper cover 15 is hingedly secured to upper casing 13 by means of pin 16 which extends through aligned openings 17 provided within upper casing 13.

Lower cover 18 is hingedly secured to lower casing 14 by means of a pin (not shown) which extends through aligned openings 19 within lower casing 14.

Upper casing 13 and lower casing 14 are framed with plastic material 20 which, in the preferred embodiment, is high impact styrene. The plastic material is also molded into projecting cars 21 through which openings 17 in upper casing 13 extend and through which openings 19 in lower casing 14 extend. A pair of posts 22, preferably made of steel, are secured to lower casing 14 and extend through casing 14 projecting upwardly. Upper casing 13 is also provided with a pair of openings 23 which are aligned with posts 22 so that the corresponding post 22 extends through the corresponding hole 23 as shown in FIG. 1.

At the end portions 24 of lower casing 14 and the end portions 25 of upper casing 13 resilient bumpers 26 are attached. These bumpers are secured in place by means of pins 27.

Both lower casing 14 and upper casing 13 are hollow. Upper casing 13 has a locking portion 28 located at one end portion thereof. Upper casing 13 also has corrugated member 30 secured thereto and longitudinally disposed therein extending intermediate said locking portion and the opposite end portion of upper casing 13. Corrugated member 30 is secured within upper casing 13 by rivet 31.

Locking portion 28 is formed with support portion 51 and screw 32 is turnably disposed therewithin. Screw 32 has shaft 33 thereupon which is preferably squareshaped and can be turned by means of key 34. The forward end portion 35 of screw 32 is adapted to extend into one of holes 23 (FIG. 7) and will lock the correspond ing post into position when operated.

With the foregoing description the operation of the instant invention may now be explained.

When it is desired to load the binder of this invention with sheets of paper (not shown) key 34 is disposed upon shaft 33 and is turned so that portion 35 is clear of corresponding hole 23. At this point upper casing 13 may be pulled clear of lower casing 14 and a plurality of sheets (not shown) having holes aligned with posts 22 can be disposed upon post 22 to the limit of the capacity of the binder which is proportional to the height of posts 22. Upper casing 13 is then replaced upon lower casing 14 and is spaced from lower casing 14 by the thickness & of the sheets. In this position the upper part of posts 22 are disposed within holes 23.

Upper casing 13 then is pressed down so that the sheets are held in firm position between upper casing 13 and lower casing 14. The pressure upon upper casing 13 is taken up by U-shaped member 29 and by corrugated member 30 so that upper casing 13 does not collapse 1n use.

Key 34' is then placed upon shaft 33 and screw 32 turned until portion 35 bears against one of posts 22 in a firm manner so as to lock upper casing 13 into position. Key 34 is then removed and binder 11 is ready for its normal use.

With the foregoing description the reader of this specification can easily see how the objects of this invention are achieved.
