Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to bookbinding structures, especially magazines,
The present invention relates to a bookbinding structure suitable for application to atlases, manuals for various instruments, music scores, and the like.

[0002]

2. Description of the Related Art Conventionally, forms such as perfect binding, overed binding, and ajiro perfect binding have been known as types of bookbinding, and they are classified into top bookbinding, normal bookbinding, notebook bookbinding, and the like.

As shown in FIG. 4, the structure of bookbinding, which has been widely known from the prior art, is such that when the bound text 1 is bound to the binding paper 3, the back surface of the binding portion 2 in the text 1 is a thin cloth or the like. The back-solidifying reinforcing cloth 4 is integrally bonded and fixed, and the central portion of the surface of the reinforcing cloth 4 is separated from the inner surface of the spine cover 5 of the binding paper 3 without being adhered. Both sides 6 and 6 remaining on both sides of the portion to which 1 is adhered are configured so that the entire surfaces thereof are directly adhered to the inner surfaces of the front cover 7 and the back cover 8 of the binding paper 3.

Further, the structure of ordinary bookbinding such as magazines and paperback books is
As shown in FIG. 6, the binding portion 2 in the collated body 1
The back surface of 1 is integrally glued with an adhesive, and the back surface of the binding portion of the main body 1 is directly bonded to the inner surface of the spine cover 5 of the binding sheet 3.

As described above, in the conventional bookbinding structure, in the case of upper bookbinding, both side edges 6 and 6 of the reinforcing cloth 4 adhered to the back surface of the binding portion 2 in the body 1 are entirely covered with the binding paper 3 described above.
Are directly adhered to the inner surfaces of the front cover 7 and the back cover 8, and in the case of parallel binding, the back surface of the binding portion 2 in the body 1 is directly adhered to the inner surface of the spine cover 5 of the binding sheet 3. Therefore, in any case, the pages close to the binding portion 2 of the text are firmly fixed to the binding paper 3 and fixed, and the text is opened as shown in FIGS. 5 and 7. At this time, the pages are not opened in a stable developed state on both sides, and the valleys 9 between the pages are opened in a deeply curved state with the deep, and each page is opened by hand. There is a troublesome problem in handling that the text will be closed if it is not pressed.

As described above, when a book, especially a thick book having a large number of pages, is opened on the desk, each page is stable unless the gap between the pages is opened deeply. The inconvenience that the pages close to the binding of each page are opened in a state where they are greatly curved, and the pages are closed immediately unless the open page is held by hand is Anyone who uses is to feel. Also, such inconvenience is remarkable especially on the pages at the beginning and the end of the book.

If the opened page is not pressed by hand,
The inconvenience that the page will close automatically means that if you need to use both hands for different purposes, such as a manual that describes how to handle a word processor or a personal computer, or a score, you can open the page. It is a very big problem because you can not hold it by hand, and in that sense, when you open the page, each page opens in a stable expanded state on both sides without the need to hold each page by hand. It is desired to provide such a bookbinding structure.

Further, unlike the conventional books, since the valleys of the binding between the pages are not opened deeply, the respective pages do not develop stably and are close to the binding of the respective pages. With the structure that the part is opened in a greatly curved state, especially in the case of a map book, there is a big problem in the form of the book that the topography of the center stitch part across both left and right pages cannot be clearly displayed. are doing. Of course, in such a case, when copying the display of the central stitch portion that straddles both the left and right pages, since the valley of the stitch is not opened, the central portion becomes black and the copy cannot be made clearly. There is a problem. It should be noted that this problem is not only a problem of map books, but is a problem common to copying conventional books.

In order to solve such a problem, a belt-shaped adhesive is applied to the inner surface of the cover sheet and the back cover of the binding sheet and the text along the back edge of the reinforcing cloth that is adhered to the back surface of the binding portion in the text. A binding structure in which the back part of the reinforcing cloth and a part of the sides up to the adhesive on both sides of the backing part are separated from the back part of the binding paper by adhering together with the adhesive.
Known by the issue.

[0010]

In this type of bookbinding structure, the loose portion between the reinforcing cloth and the spine portion of the binding sheet, which is adhered to the back surface of the binding portion in the text, is certainly not limited to the spine portion but is on both sides. Since it extends to the back edge where the adhesive is applied, when the text is opened, the back part of the reinforcing cloth is flat due to the loose parts with a slight gap to the adhesive on both sides of the reinforcing cloth. As long as it is bent into a V shape,
Compared with the conventional bookbinding structure shown in and 7, it is possible to greatly expand the valley between pages.

However, even though the above-described bookbinding structure has an excellent advantage that the valley between pages can be greatly expanded as compared with the conventional bookbinding structure, this type of bookbinding structure has been generally used until now. One of the reasons why it does not spread is the structure that a U-shaped loose part including the back surface and the back edges on both sides is provided between the reinforcing cloth adhered to the back surface of the binding part and the back part of the binding paper. , Because it is common to all books with different thicknesses, there is a problem that books with different thicknesses may or may not greatly expand the valley between pages. To have.

Another reason why this type of bookbinding structure is not widespread is that, in the bookbinding structure, as a means for connecting the text and the outer binding paper, a reinforcing cloth and a binding material attached to the back surface of the binding portion of the text are used. Since the back of the paper is simply bonded by the adhesive area of the limited area on both back edges of the reinforcing cloth, the joint strength between the text and the binding paper is weak, and the page opening Since this adhesive part is pulled every time, the adhesive part is easily damaged during use, and the text and binding paper are separated, making it impossible to maintain the structure as a book. This is because it has points.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the bookbinding structure according to the present invention will be described with reference to the embodiment shown in the drawings. As shown in FIG.
The back of 1 is made of a thin cloth like cold chill, and is a back-strengthening reinforcing cloth 1
2 is integrally bonded and fixed by means of the reinforcing cloth 12 on the surface 1
2a is arranged so as to separate the non-adhesive separating portion 15 from the inner surface of the spine cover 14 of the binding sheet 13, and both side edges 16, 16
Is adhered to the inner surfaces of the front cover 17 and the back cover 18 of the binding paper 13.

The binding sheet 13 has a pair of folding line portions 19 and 20 which are parallel to each other between the front cover 17 and the back cover 18 on both sides of the spine cover 14.

Further, the reinforcing cloth 12 has both sides 16,1.
Between the shoulder edges 21 and 21 of 6 and the inside of the folding line portions 19 and 20 on both sides of the spine cover 14 of the binding paper 13, continuous non-bonding with the separating portion 15 on the back surface of the binding portion 11 is performed. Since the floating separating portion 22 is provided, the edges 16a and 16b of the both side edges 16 and 16 are formed so that the binding paper 13
The end piece 2 that is adhered to both the front cover 17 and the back cover 18 and is adhered to the entire inner surfaces of the front cover 17 and the back cover 18.
The inner side ends 23a and 23b of 3 are adhered to each other, and the back side 2
It is firmly fixed to the front cover 17 and the back cover 18 by means of No. 3.

The width H of the floating separating portion 22 is set within the range of ⅕ to ½ of the thickness of the body 10. The width H of the floating separating portion 22 may be varied depending on the thickness of the body 10, and when the thickness of the body 10 is small, the width of the floating separating portion 22 may be small, but when the thickness of the body 10 is large. In particular, it is preferable to increase the width of the floating separating portion 22 and generally set it to about one third to one half as shown in FIG.

[0021]

According to the bookbinding structure of the present invention, the back-setting reinforcing cloth 12 for integrally bonding the back surfaces of the binding portions 11 in the text 10 together.
The front surface 12a of the binding paper 13 is separated from the inner surface of the spine cover 15 of the binding paper 13, and both side edges 16, 16 of the reinforcing cloth bonded to the inner surfaces of the front cover 17 and the back cover 18 of the binding paper 13, both shoulder edges 21, 21 has a non-adhesive floating separation portion 22 between the inside of the folding line portions 19 and 20 of the spine cover 14 of the binding paper 13, and its end edges 16a and 16b are
Since the inner edge of the end piece 23 fixes the inner surface of the front cover 17 and the inner surface of the back cover 18 of the binding sheet 13, the floating separating section 22 separates the area of the separating section 15 between the binding section 11 and the inner surface of the spine cover 15. , Extended to both sides, reinforcing cloth 12
Can be relatively freely moved with respect to the spine cover 15.

That is, both sides 16, 16 of the reinforcing cloth 12
2 by setting the width H of the floating separation portion 22 between the cover sheet 13 and both sides of the spine cover 14 to be about one third to one half of the thickness of the body 10. When the main body 10 is opened at the middle portion as described above, the surface 12a of the reinforcing cloth 12 is bent in a V shape so that the upper edge portions of the floating separating portions 22 on both sides are located at the center of the inner surface of the spine cover 15. By pulling with a margin in the direction of the part, it is possible to open to a size such that the valley between the pages is almost flat.

When the main body 10 is opened at one side as shown in FIG. 3, one floating separation portion 22 causes one side of the surface 12a of the reinforcing cloth 12 and the spine cover 14 to be largely separated from each other, and The floating separating portion 22 (upper floating separating portion 22 in FIG. 3) is neatly bent into a horizontal portion and a vertical portion, so that the seam 11 of each page is wide open and the left and right pages are not bent. It can be deployed stably.

Further, the spine cover 14 of the binding paper 13 is the text 1
When 0 is opened, the insides of the folding line parts 19 and 20 are separated from the both side faces of the binding part 11 by the floating separating part 22, so that the folding line parts 19 and 20 contract and bend into S-shapes, and the reinforcing cloth both side sides 16 and 16 are bent.
Of the back cover folding line portions 19 and 20 without pulling them, the reinforcing cloth 12 is bent inward toward the inside as described above, or is bent into a horizontal portion and a vertical portion. To facilitate.

Further, in the bookbinding structure of the present invention, the reinforcing cloth 12
The edges 16a and 16b of both side edges 16 and 16 are adhered to the front cover 17 and the back cover 18 of the binding sheet 13, and the entire inner surface of the front cover 17 and the back cover 18 is provided on the surfaces of these edges 16a and 16b. Inner end 2 of the end piece 23 adhered to
3a and 23b are adhered to each other, and the surfaces of the edges 16a and 16b are fixed to the front cover 17 and the back cover 18 by the look-back 23, so that both side edges 16a and 16b of the reinforcing cloth 12 and the binding sheet 13 are fixed. The joining is extremely strong, and it is possible to surely solve the problem of the conventional bookbinding structure of this type in which the reinforcing cloth 12 is peeled from the binding paper 13 even if the page is opened and closed frequently.

As described above, according to this bookbinding structure, no matter which part of the text is opened, the seams of the respective pages can be widened and the pages can be stably spread left and right without being curved. Since it is possible to apply it to various binding forms such as perfect binding, binding binding, and ajiro perfect binding, it is not necessary to hold open pages by hand. Great for binding, and also
Since it is suitable for copying because it can open the page stitch widely, it can be widely used for binding all kinds of books and magazines.
