Description
REINFORCING MEMBER FOR PAPERBACK BOOK COVERS
FIELD OF THE INVENTION
The present invention relates to a cover reinforcement for paperback books and similar materials, and more particularly to a bendable, reinforcing means that can be fixed to the inside cover of paperback books and similar materials to prevent deformation or to correct previous damage to the book cover, such as curled or bent corners.
BACKGROUND OF THE INVENTION
The covers of paperback books are very susceptible to damage through the course of their lifetime due to their lack of rigidity, often leaving the enclosed pages with less protection and prone to further damage. Numerous types of book covers and corner guards already exist with the goal of preventing the covers or corners of books from becoming damaged due to the normal wear and tear of everyday usc;, or they at least aim at lessening the extent of this damage. However, these pre-existing designs are not equipped with the possibility of correcting damage that has already occurred.
Typical protective book covers are those made out of sheets of heavy paper or plastic that are wrapped around the outside of books and fixed to the inside of their front and back covers. These types of covers, however, offer no solution if the cover was accidentally bent backwards. The same is true for typical corner guard devices that may prevent the tip of the corner from being bent, but do nothing to protect the rest of the cover.
PRIOR ART
Villafana U.S. Pat. No. 4,08?~,582 discloses a book protector consisting of an elongated, flexible material with a zipper sewn along the center axis that divides the material in half. The protector is fixed to the book cover by means of an adhesive strip located on the outer edge of each half. When the protector is attached to the book and the zipper is closed the book is unable to open, therefore :if the book is dropped or carelessly placed in a bag, the cover and the inner pages are protected from damage. However, if the book is dropped or mishandled while being used, the zipper in this instance is open and there is nothing to prevent the cover from being damaged.
Lee U.S. Pat. No. 5,533,75$ discloses a book cover corner guard that aims to prevent the corners from being bent or torn by adhering a guard body to the outside cover of the book.
Although this invention makes the corner of the book more rigid, it does not prevent the book cover from being creased or damaged outside the area of the corner guard, and it does not provide a means for correcting damage to the cover of the book.
SUMMARY OF THE INVENTION
The present invention involves the attachment of a reinforcing means to the inside cover of paperback books, which is comprised of fme ribs or arms that extend toward the outer corners of the cover, or of a mesh that covers a large area of the inside surface of the cover of the book. The type of material used for the reinforcing means depends on properties necessary for the use of the cover reinforcement such as strength, flexibility, and elasticity.
These characteristics indicate that a type of plastic or metal be used to construct the reinforcing means. It is essential to t:he design that, when inserted, the reinforcement does not protrude excessively from the book or make the book awkward to handle.
Therefore, the device should be relatively flat. As well, the invention should not be unsightly in appearance so as not to detract from the book. Since the bottom surface of the reinforcing means is intended to permanently attach to the inside surface of the cover, in a preferred embodiment, it is coated with an adhesive layer that is revealed by peeling away a protective backing. With the device in place, if the cover becomes bent as a result of wear and tear, the flexible and pliable nature of the reinforcement will restore the cover to its original state. The invention can be attached to brand new books in order to prevent damage from occurring, or used with older books in order to provide a means for correcting damage that has occurred in the past.

FIGS. 1-9 show several preferred embodiments of the present invention involving the attachment of a reinforcing means to the surface of the inside of the cover 12 of a paperback book 10 having curled free end corners 13. The reinforcing means can be in the form of a reinforcing member 16 as shown in F'IG. 2, consisting of free ends that extend towards the free end corners 13 of the paperback 'book cover 12 and of non-free ends that are connected at a point proximal to the spine of the paperback book 10. In other embodiments (FIGS. 3-4) the reinforcing means may comprise a fine, reinforcing mesh 18 or unconnected members 22.
The type of material used for the reinforcing means depends on properties necessary for the use of the cover reinforcement such as strength, stiffness, and elasticity.
Another characteristic of the material used to construct the reinforcing means is that, in certain embodiments, the reinforcing member 16 or the reinforcing mesh 18 must be able to be cut to the desired size to fit neatly on the inside cover 12 of the paperback book 10 using household scissors. Therefore, in preferred embodiments the reinforcing means is constructed from plastic or metal.
In the embodiment shown in 11G. 2, the reinforcing means comprises a reinforcing member 16 consisting of ribs or arms with free ends that extend to the free-end corners of the cover of the paperback book and joined ends which are attached to the cover 12 near the spine of the paperback book 10. The bottom surface of the reinforcing member 16 is intended to permanently attach to the inside surface of the cover 12. One method of affixing the invention is to coat the bottom surface of the reinforcing member 16 with an adhesive layer 24 that is activated by peeling away a protective backing 26, as depicted in FIG. 5.
Another means of attachment is to provide a separate piece of adhesive material 23, for example tape, having a width larger than that of the reinforcing member 16 which is applied over the top surface of the reinforcing member 16 as shown in FIG. 2. It is essential to the design that the cover reinforcement does not protrude excessively inwardly from the inside cover of the paperback book 10 or make the book awkward to handle. Therefore, the thickness of the reinforcing member 16 is limited such that it does not prevent the cover 12 from properly closing, as depicted in FIG.6. In preferred embodiments, the thickness of either of the reinforcing means is less than 3mm.
A further embodiment for the invention, shown in FIG. 7 includes a pivoting joint 28 that connects to the non-free ends of the reinforcing member 16. The pivoting joint 28 allows the free ends of the reinforcing member 16 to rotate so that they can be directed towards the free end corners 13 of the paperback book cover 12. This makes the invention adaptable to different sized books. The above-mentioned thickness limitation applies to the pivoting joint.
Adaptations to provide a pivoting joint are well known to persons skilled in the art.
A preferred embodiment is shown in FIG. 9. In addition to the pivoting connecting joint 28, the reinforcing arms 22 are adapted to be extensible as indicated by the extending mechanism 30. The extending mechanism 30 may consist of one of the arm segments 32 sliding in a track of another arm segment 34. Alternatively, a slot and peg formation may be used, or any other similar functioning device known to those skilled in the art. It should also be noted that whichever extending mechanism 30 is used, the above mentioned thickness limitation applies. The combination of the pivot and the extensible feature allow the free ends of the reinforcing member l 6 to be positioned to the appropriate length and angled so that the reinforcing member 16 fits neatly on the inside cover while the free ends extend to reach the free end corners 13 of the cover 12 of the paperback book 10. This embodiment is even more suited to books of different sizes since the free ends of the reinforcing member 16 can be adjusted to reach the tip of the free end corners 13 rather than just being directed towards them as in the embodiment of FIG. 7, In another embodiment, the invention consists of individual ribs or arms 22 as shown in FIG. 4. The individual arms 22 are affixed to the inside cover of the paperback book 10 such that one end is directed towards the free end corners 13 of the cover 12, while the other end of the arm 22 is fixed at a point proximal to the spine of the paperback book 10. In this embodiment, a plurality of individual arms 22 can be affixed to the cover 12 in order to restore the cover 12 to its original state. The aforementioned material characteristics and thickness limitation apply to this embodiment as well. 'the individual arms 22 can be conveniently provided in a kit as shown in FIG. 8. Each arm is adhered to a plastic surface 27 from which it may be peeled to expose the adhesive substance on their bottom surface thereof.
As well, the extensible feature described above can also be used for the individual arms 22.
An alternative embodiment for the reinforcing means is the reinforcing mesh 18 depicted in FIG. 3. The reinforcing mesh 18 is comprised of filaments 20 that are woven together and that are made from material with the required strength, stiffness and elastic qualities described above. Similar adhering means such as a coated bottom surface with protective backing, or separate adhering material that is larger in surface area than the mesh 18 itself, can be used to affix the mesh to the inside cover 12 of the paperback book 10. The same thickness limitation that applied to the other embodiments of the invention applies to the reinforcing mesh 18 as well.
