Devices and Methods for Supporting Printed Matter

Abstract

A book block and/or set of print matter is contemplated to be bound in individual sections through various techniques. These sections will be unbound or stitched to section covers or glued to section covers. These sections will then be augmented with attachment members to allow sections to be secured to each other or a book cover. These attachment members may be secured to the sections through a permanent or non-permanent manner, ranging including tension and/or clamping and/or crimping and/or sewing/stitching and/or gluing. The user of the book will then be allowed to select and detach individual sections of the book block or set of print matter without destroying the integrity of the entire book block or set of print matter. Likewise, publishers of the book are now able to update and/or replace sections of an entire book block and/or print matter without needing to reprint and republish the whole book or set of print matter.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to supporting of printed matter. In particular, the present invention relates to the support of various reading and/or viewing printed material including books, brochures, catalogs and the like.

2. Background of the Invention

As the volume of literature increases, additional costs are associated with the manufacture of printed material, including books, brochures, catalogs, magazines, and the like. Some of this printed matter becomes very large or heavy, particularly because of their tremendous volume or size. Despite the advancement of literature and information, conventional methods of manufacture in the art of bookbinding have been relatively constant and have essentially been limited to (i) case binding and (ii) perfect binding. Traditional Smyth sewn books require a series of arranging, sewing, and gluing steps to adhere signatures (sections of the entire book) to the cover spine. Typically, textbooks and other large-mass books employ the Smyth sewn binding technique.

Perfect bound books mainly require an adhesive binding between the book block and the cover. After the technological booms following World War II, perfect binding became an economical option for many publishers, making it a common practice in contemporary times. Nearly all paperback books, telephone books, and other small-mass books are bound using the perfect binding technique.

Large-mass books are typically perfect bound or bound using the Smyth sewn technique. Many of these large-mass books are published in the form of textbooks or trade books for school students. Such large and heavy books take their toll on those who have to carry these books on a daily or regular basis, typically students. The American Chiropractic Association (ACA) and the American Occupational Therapy Association (AOTA) states that children should not carry more than 10% of their bodyweight. Researchers have found, however, that children are carrying 22% of their bodyweight in studies conducted in the United States.

The National Safety Council states that according to the US Consumer Product Safety Commission there were more than 21,000 backpack related injuries that ended up being treated in emergency rooms, clinics and doctors' offices in 2003. The range of these injuries was widespread from contusions, to sprains, and even fractures.

The American Chiropractic Association states in an August 2010 article that children have the same rate of back pain as full grown adults by the time they have reached just 14 years of age. This can cause chronic and long-term injury to the current and future generations of school children.

Some subject matters require new versions of texts in order to account for changes that took place after the initial publication of the book. Using bookbinding methods of the art, the entire text is replaced when revisions are made to a sufficient number of sections. Some fields, such as legal texts, use “pocket parts,” which are smaller independent sections showing only the changes; but the main body of text is unchanged, and both the main body of text and the pocket part must be referenced in order to read the actual updated text. Using existing techniques of the art, there is no other way to replace merely a section of the book.

Thus, there is a need in the art for a more effective technique for manufacturing printed matter such that portions of the printed matter may be carried independently of the other portions, and allowed to be changed, revised or replaced without having to do so for the entire volume in which such portion is a part. The technique should be simple to understand, use and manufacture so that it provides an efficient and less costly alternative to constant volume changes and/or provides an efficient method of carrying just one portion of a large size or volume printed matter.

SUMMARY OF THE INVENTION

The present invention provides a unique technique of assembling, organizing and/or manufacturing bound or unbound print matter such that such matter may be easily taken apart into defined portions and each portion carried or reviewed independently of the other. Though examples throughout this application may focus on particular types of printed matter for sake of simplicity, it should be known that the techniques disclosed here are applicable to all types of matter having multiple portions as would be evident to one having ordinary skill in the art after consideration of the present disclosure. Each such portion can also be independently updated or revised without affecting the other portions of the matter that have not been changed. The present invention overcomes many disadvantages associated with conventional bookbinding and manufacturing techniques by using a novel and simple technique of combining interlocking components that comprise sections of a reading material, such as a book. Book users need not transport the entirety of a book when they only desire to focus on one chapter or section of the book. With the present invention, the book user can select the portion(s) of the book she would like to carry with her. Likewise, book publishers need not reprint the entirety of a book when they desire to alter select chapters or sections of the book. With the present invention, the book publisher can select portion(s) of the book that it would like to update, reprint, and sell. Such technique is more advantageous to the publisher, because only certain portions of a, for example, textbook are revised and the cost of printing is limited to those particular portions, such as a chapter. That individual portion can then be sold at a substantially reduced rate than having to reprint and sell the entire textbook. Such high costs of having to re-publish an entire book also prevent many buyers from purchasing new versions because of the lack of substantial difference from older versions of the same textbook. Thus, with the present technique, the publishers can realize higher sales of relevant portions of a textbook because consumers are more apt to purchase those portions of a textbook that are updated rather than an entirely reprinted new textbook.

Using techniques presented herein and according to the present invention, portions or sections of a book will be individually bound, such as, but not limited to, a perfect binding method. These smaller sections of the whole textbook could be gathered under a book cover. The force used for attraction between the sections and the book cover would be strong enough to keep the entire book block together, when this is the desired use. The sections can also be detached from the book cover and carried separately. A few examples of forces used for attaching the detachable sections include magnetic and mechanical techniques.

For sake of simplicity, exemplary techniques that may be used in conjunction with the present invention have been presented in various groups of embodiments. Also, for sake of simplicity, the various embodiments are presented with use of a “book” for sake of simplicity. However, the present invention and techniques are equally applicable to other forms of printed and bound and unbound matter, including but not limited to, magazines, directories, newspapers, brochures, photographic albums, reports, and the like. In a non-limiting example of unbound material, techniques disclosed in the present invention may be used to assemble previously unbound materials into a cohesive unit, as well as serving as binding for different sections of the unbound printed matter. One of ordinary skill in the art would be cognizant of these and other type of printed or photographic matter that could be used by the techniques presented in the present disclosure. All such uses are within the scope of the present invention.

The mechanical embodiments explained in the present invention provide mechanical methods of fastening the sections to the book cover or fastening the book sections to one another. Examples of mechanically-attaching mechanisms include but are not limited to a series of interlocking male and female elements, such as a hook-and-slot mechanism. Many other mechanical binding devices may be used and such other devices are apparent to one having ordinary skill in the art and thereby within the scope of the present invention.

The sections (or chapters) of a sectional book constructed using the mechanical method can be mechanically-adhered to the book cover or each other, so that each section may be independently separated from the entire book block. Thus, sections of the book can be individually bound, and the book cover and/or section covers can include at least one mechanically-attaching member.

The present invention has many uses and advantages as would be apparent to one having ordinary skill in the art after consideration of the present disclosure. Exemplary non-limiting uses and advantages over conventional techniques include, but are not limited to: providing a convenient way for users to select which portions of a book to carry with them; providing a reduction in overall weight carried by the user in the forms of books; providing a way for reducing back-related injuries due to carrying heavy books; providing book publishers a way to update portions of the book without need to reprint the entire book; providing book publishers a way to reduce their overall cost of production for new and/or updated versions of books.

The following is a non-limiting list of exemplary mechanical embodiments of the present invention. For the purpose of this disclosure, the term “module member” includes section member(s), booklet member(s), stitch-bound member(s), and unbound print member(s). Section members 30A and 30B can be attached to the book cover 10 through adjoining members. Section members 30A and 30B can also be attached to each other. For sake of simplicity, many of the drawings present a combination of section members, e.g., 30A and 30B, while only showing section member 30A. It is to be understood in these drawings that a section member 30B may be attached to section member 30A, similar to what is shown and described in FIGS. 1A-1D. Additionally, it is to be understood that the components of section member 30B, such as a spine region 35B of section member 30B, are also present as a complement to those of section member 30A. Further, the description of many of the drawings discusses, for instance, a slot element of section member 30B corresponding to a hook element of section member 30A. Such a slot element is understood to act similar to a slot element shown of section member 30A in receiving a hook element. Additionally, in order to show commonalities between drawings, many of the drawing label features are not specifically discussed with respect to the drawing. These features are commonly numbered as they represent an equivalent feature. One having ordinary skill in the art would recognize and understand each embodiment shown and presented in view of the description presented for other embodiments. Booklet member 40A can be attached to the book cover 10 through adjoining members or any other member with complimentary hook-and-slot elements. Stitch-bound members 50A and 50B can be attached to each other through adjoining members or any other member with complimentary hook and/or slot elements. Unbound print members 60A and 60B can be attached to each other through adjoining members or any other member with complimentary hook and/or slot elements.

Combinations of attaching the section member(s) 30A and/or 30B, booklet member(s) 40A, stitch-bound member(s) 50A and/or 50B, and unbound print member(s) 60A and/or 60B to each other and/or to cover 10 by adjoining members include but are not limited to (i) hook-and-slot, (ii) slot-and-hook, (iii) sliding hook-and-slot, (iv) sliding slot-and-hook, (v) interlocking sliding hook-and-slot, and (vi) interlocking slot-and-hook.

The attaching members of these embodiments are made of flexible and durable materials (such as plastic and/or rubber and/or metal), which would be affixed to the book cover and/or section member(s) and/or booklet member(s) and/or stitch member(s) and/or unbound print member(s). These members may be affixed in a variety of permanent or non-permanent ways, such as gluing, taping, sewing, clasping, crimping, or interlocking. Thus, the attaching mechanism may be reversible or irreversible, depending on the desire of the manufacturer and/or user. The most likely method for affixing members described in embodiments attaching section member(s) 30A and/or 30B to each other or to book cover 10 is gluing. On the other hand, the embodiments section member(s) 30A and/or 30B, booklet member 40A, stitch-bound member(s) 50A and/or 50B, and unbound print member(s) 60A and/or 60B to each other and/or to cover 10 may require additional strength by employing additional clamping and/or sewing and/or crimping. The composition base of the adhesive used to affix attaching members to the book cover 10 and/or section member(s) 30A and/or 30B and/or booklet member 40A, and/or stitch bound member(s) 50A and/or 50B, and unbound print member(s) 60A and/or 60B may include but is not limited to a polyvinyl acetate (PVA), Polyurethane (PUR), plastic resin, ground animal, ground hide, liquid hide, or caoutchouc (raw rubber).

Attachment members described in the present invention may be manufactured for a specific width and/or height of print matter. It is envisioned, however, that while most attachment members can accommodate a variety of widths of print matter, the height of the attachment member may be predetermined or created for modularity after initial fabrication.
