BINDER FOR MAGAZINES AND THE LIKE Filed Jan. '7, 1964 Mil/4M M Q04F74/V BY v AM firm/mama .bone.

United States Patent 3,252,462 BINDER FOR MAGAZINES AND THE LIKE William M. Quarton and Robert D. Riley, both of Madison, Wis., assignors to Demco Library Supplies, Incorporated, Madison, Wis., a corporation of Wisconsin Filed Jan. 7, 1964, Ser. No. 336,236 1 Claim. (Cl. 129-38) This invention relates to a binder for magazines and the like.

The invention is concerned with the construction of a so-called backbone and the manner in which the backbone is attached to the back of the binder. The backbone comprises a relatively rigid channel-shaped member which is usually made of metal but may be made of any other appropriate material. It is 'provided at its ends with heads, one of which pivotally supports a binding bar which has a free end detachably engaged with and ordinarily locked or otherwise secured to the head at the other end of the backbone.

The channel-shaped member between the two heads is completely enclosed in a plastic sheath which has inverted channels embracing the respective flanges of the back- These flange-enclosing channels are connected by a web which crosses the bottom of the backbone. The sheath has external flanges which project laterally in opposite directions from the backbone and are connected with the cove-r in any desired manner, as by-heat sealing or adhesive or stitching, heat sealing being preferred if the materials used are appropriate. When the backbone is assembled with the sheath, the sheath provides a complete lining for the interior of the backbone from one head to the other. Thus, with the sheath anchored to the back portion of the cover, the backbone is securely centered in the cover.

An insert of sponge rubber or the like is fitted into the lined backbone and it may be adhered thereto, although, particularly if made slightly oversize and pushed into place, no other connection is needed.

When thebinding bar is released and pivoted to its open position, the bight of a pamphlet or magazine to be bound can be placed on the sponge rubber pad within the backbone, whereupon it will become clamped between the retaining bar and the pad when the retaining bar is returned to its closed or locked position.

In the drawings:

FIG. 1 is a view in perspective showing a preferred embodiment of a binder incorporating the invention.

FIG. 2 is an enlarged detail view in perspective fragmentarily showing the open binder, the backbone and its sheath being exposed and portions of the sheath being broken away.

FIG. 3 is a further enlarged detail view in perspective fragmentarily illustrating the sheath per se.

FIG. 4 is a still further enlarged detail view taken in cross section on the line IVIV of FIG. 2.

The jacket 5 comprises a pair of covers 6 and 8 wh ch may comprise a single sheet of appropriate flexible material or, as in the present instance, may comprise two separate sheets of different materials joined at seam 10 by heat sealing or otherwise, the cover 8 and the back extension 12 thereof being opaque and the cover 6 being transparent.

The back portion 12 of the jacket embraces a backbone which is fixed thereto as hereinafter described and includes a relatively rigid channel 16 having a bottom Web 18 and upstanding laterally spaced flanges 20. The channel 16 is closed at its ends by heads 22 and 24 which position the binding bar 26. This bar is pivoted in a known manner to the head 22 as by pintle 23 for oscillation between the clamping positions shown in FIG. 2 to and beyond the dotted line position illustrated in that ice figure. In accordance with conventional practice, means is desirably provided at the head 24 for locking the end portion 28 of the binding ba-r releasably to the head 24. Since the particular locking means forms no part of the present invention, and locking means of various types are in common use, the details of the locking means are not here disclosed but the key slot 25 is shown.

In order to connect the channel 20 to the portion 12 of the jacket, the backbone includes a sheath which is pre-formed, desirably by extruding plastic, the sheath 30 per se being fragmentarily illustrated in FIG. 3. The sheath is designed to fit the channel 16. It comprises a Web portion 32 which is in face contact with the whole inner surface of web 18 of channel 16. The sheath further comprises inverted channeled side members 34 which embrace both sides and the top margins of the respective flanges 20 and terminate in oppositely projecting flange portions 36 which lie on, and are permanently connected with, the back portion-12 of the jacket, between the covers 6 and 8. In the instant device, both the jacket and the sheath are made of heat scalable plastic material so it is convenient to provide a heat sealed connection at 38 between the sheath and the jacket.

Within the backbone, we provide a cushion 40 which is conveniently made of sponge rubberor the like and compressed when pushed into the sheathed channel 20. It does not require adhesive and, consequently, it is immaterial whether adhesive is used to secure the cushion in place.

In the use of the device, a magazine or pamphlet 42 is opened centrally at its bight 44, as best shown in FIG. 4, and is engaged beneath the binding bar 26. When the bar is restored to the position shown in full lines in FIG. 2 and its end portion 28 is fixed within the head 24, the work 42 is clamped between the binding bar and the yieldable cushion 40. The magazine may readily be opened to any desired page without displacing it from its position in clamped connection with the backbone and between the covers of the jacket.

Assuming that one of the covers is made of transparent plastic, as shown at 6, any printing on the cover of the pamplet will be clearly visible, even in the closed position in which the jacket cover 6 is shown in FIG. 1.

The sheath can be made of plastic material comparable to that used in making portions 3 and 12 of the jacket and, consequently, it is not only an attractive means of finishing the backbone consistently with the jacket, but it also serves as a simple and unusually effective means of anchoring the backbone permanently to the jacket in a position from which it cannot shift in use. The sheath is the same length as the channel 16 and, consequently, the ends of the sheath are in abutment with the heads 22 and 24 of the backbone, thus precluding relative longitudinal displacement. The heat sealed connection at 38 between the flanges 36 of the sheath and the back portion 12 of the jacket precludes any lateral displacement of the backbone.

The cushion 40, coacting with the binding bar 26, is a particularly effective means of clamping the work releasably to the backbone. Regardless of the thickness of the magazine or pamphlet which is to be bound, the cushion 40 will yield under the thrust of the bar 26 and its resilience will maintain a secure clamping engagement with the bight of the work.

We claim:

A binder for work such as magazines and pamphlets folded to comprise a bight, said binder comprising a jacket having a back portion and covers, a backbone consisting of a substantially rigid channeled member extending longitudinally of the back portion between the covers and having upstanding flanges and heads at =3 the ends of the channeled member, a sheath of extruded plastic enveloping said member and having lateral flanges extending in opposite directions therefrom along said back portion, said sheath lining the interior of the channeled member, and means connecting said lateral flanges of the sheath to said back portion for anchoring the backbone, the backbone including a binding bar pivoted at one end to one of said heads at one end of the backbone and releasably engaged at its other end to the other head at the other end of the backbone, said bar being receivable into the bight of the work and constituting means for clamping the work to the backbone, and a cushion of resiliently yieldable compressed sponge material substantially filling the channel within the sheath lining the interior thereof and under lateral pressure between the upstanding flanges of the backbone to retain same therein and providing a clamping means coacting with said bar in the anchoring to the binder of the bight of work placed I therein.
