Description

The present invention relates to a book cover that is free size with respect to thickness.

The size of a book is usually different even if the vertical and horizontal dimensions of the book are the same. For this reason, books with different thicknesses could not be covered with a single book cover. As a method for solving this problem, for example, (Patent Document 1) JP-A-9-277741 and (Patent Document 2) JP-A-2007-261230 by the same applicant are disclosed.

Japanese Patent Laid-Open No. 9-277741 JP 2007-261230 A

However, in the above (patent document), a pair of cover pieces are overlapped in a complicated manner at the position of the back cover of the book, and the engaging part is exposed on the outside of the cover. It was easy to do. Also, the appearance was not good, and the cover was sometimes detached. Therefore, a solution found in (Patent Document 2) by the same applicant, that is, a method of covering the engaging portion with another cover piece and further adding a holding piece to prevent the cover from being detached has been taken.

However, including this measure, the cover structure has become more complex. In addition, the back of the book is the place where you can touch most when reading or carrying it, and it is not only in appearance but also used to create a superimposed engagement part or add a new cover. The feeling was not good either.

Even when the holding piece is attached, in use, since the book is simply placed on the cover and the both ends are simply folded, the cover and the book are not stably fixed and are always easily displaced. This is because the front cover part and the back cover part of the cover are connected by the back part of the book which is most easily deformed, which promotes the deviation.

Furthermore, in (Patent Document 1), in order to prevent the cover piece 1 and the cover piece 2 from being easily separated and falling off from the book, the trouble of “joining the connecting portion by sewing or the like after assembling” is performed. Such a solution was shown.

Therefore, the present invention eliminates the above-mentioned conventional drawbacks, has a simpler structure, is easy to make, has a good appearance, is easy to attach and detach, is stable and easy to use, and has excellent usability and durability. The challenge is to provide a free book cover.

In order to solve the above-mentioned problem, the book cover according to claim 1 is provided with a main cover A portion having a length corresponding to the width of the open book, provided with a pocket portion for inserting a front cover of the book, and a back cover. Consists of two independent body B parts with a length corresponding to the width of the back cover, provided with a pocket for insertion, provided at the opposite end of the pocket part in the body A part The part is inserted into the insertion hole provided in the middle of the main part B, so that the two bodies are connected and the two bodies slide relatively, so that the total length of the book cover can be changed, The first feature is that it can cope with different thicknesses of books. In addition, the stopper provided at the end of the connection part of the main part A is inserted into the insertion hole by bending, and by returning it to the original position, the slide width is limited and the main part A and the main part B are separated. Preventing is the second feature. Further, the third feature is that the connecting portion inserted from the insertion hole fits in the pocket and is covered with the pocket.

The present invention has the following effects. In the invention described in claim 1, since the insertion hole and the connecting portion are both on the back cover side plane, and the back cover portion has no structural portion thereof, not only the connection is stabilized, but also the back cover portion The appearance is good, and the hand feels good when reading or carrying.

Further, since the cover of the book is inserted and fixed in the pockets on both sides, the mounting stability of the cover is increased.

Also, the main part A is simple and easy to handle because there are no “both tongues” as described in (Patent Document 1) and (Patent Document 2) and no “gap” between this and the “central tongue”. . In addition, the body B portion does not need a “central tongue” that is slightly connected by the “engagement end” as described in (Patent Document 1) and (Patent Document 2), and the insertion hole is located in the body B portion. It can be opened as much as possible, increasing the degree of freedom in designing the connecting portion, and increasing the durability during use.

Further, the invention according to claim 2 can be formed with only a cut shape without a new joint such as stitching, and the stoper portion is on the side of the connecting portion to be inserted into the insertion hole.

Further, the invention of claim 3 is that the connecting portion that has passed through the insertion hole fits in the flat pocket portion of the main body B portion and is hidden, so that the cover is stable, the deformation of the stopper portion is suppressed, and the appearance is also very good. It can be refreshed.

It is a top view which shows the cutting shape before an assembly. It is a block diagram which shows completion. It is a perspective view with which the book is mounted | worn. It is a perspective view which shows the book with which the cover was mounted | worn. It is a perspective view which shows another example. It is a perspective view which shows another example.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an example of a material cutting shape before assembly in a book cover according to the present invention. FIG. 2 is a block diagram showing the completed book cover. FIG. 3 is a perspective view showing how to attach a book cover to a book. FIG. 4 is a perspective view showing a book with a book cover attached thereto.

Referring to FIGS. 1 and 2, the book cover of the present invention is basically composed of a main body A portion 1 and a main body B portion 2 formed by cutting sheet-like materials such as leather, cardboard, and plastic. Composed of body assembly.

The body A portion 1 is valley-folded at a fold line 3 and joined by bonding or sewing at the upper margin portion 4a and the lower margin portion 4b to form the front cover insertion pocket 5 of FIG. Similarly, the main body B portion 2 is also valley-folded at the fold line 6 and joined at the upper margin portion 7a and the lower margin portion 7b to form the back cover insertion pocket 8.

The width b1 of the main part A 1 is set to a value obtained by adding the minimum value of the assumed book thickness t1 to twice the width b3 of the book cover. The lateral width b2 of the main body B portion 2 is set to be slightly shorter than the lateral dimension b3 of the book cover.

In FIG. 2, a3 indicates the vertical dimension of the cover of the book inserted into the pocket, and the pocket width a4 is made slightly larger than the vertical dimension a3 of the cover, so that the cover can be easily taken in and out. a5 is the vertical dimension of the book cover, and is a value obtained by adding up and down margins to the pocket width a4. The pocket depth p1 is arbitrary in principle, but it is about half of the lateral dimension b3 of the cover in consideration of taking in and out of the cover and removal of the cover at the time of use.

Returning to FIG. 1, a connecting portion 9 surrounded by a connecting portion width a1 and an adjustment margin T is formed on the left end side of the main body A portion 1, and a slit-like insertion hole provided at a position L1 to be described later of the main body B portion 2. 10 is inserted from the direction indicated by the arrow 11. Here, the curve part c is a mere appearance design shape. Further, 12a and 12b provided on the upper and lower left sides of the connecting portion 9 are stoppers which will be described later. When inserted into the insertion hole 10, they are bent and returned to their original shape after insertion.

The dimension a2 of the insertion hole is slightly larger than the width a1 of the connecting portion, and the connecting portion 9 can smoothly slide in the range of the adjustment margin T in the insertion hole 10.

That is, in FIG. 2, the main body A part 1 and the main body B part 2 having the cover insertion pocket are connected by the connecting part 9 inserted into the insertion hole 10, and the book cover total length L, which is the connection length. Is adjustable only by T, and the stoppers 12a and 12b limit the movable range and prevent the main body A part 1 and the main body B part 2 from being separated.

FIG. 3 is a diagram in which the completed book cover of FIG. 2 is actually attached to a book. The front cover 13 and back cover 14 of the book are put in the book cover insertion pockets 5 and 8, respectively, and the book cover total length L within the range of T to adjust for variations in the thickness of different books appearing on the back cover 15. By adjusting the, the book cover is shown to be optimally and cleanly attached to the book.

Here, when the thinnest book is assumed, the total cover length L is the shortest, and FIG. 2 shows the state. Further, it is obvious that the position L1 of the insertion hole 10 can be determined from an adjustment margin T that is an increase in the thickness of the assumed book and the length of the stopper portion.

The back cover side pocket depth p2 is longer than the position L1 of the insertion hole 10 to conceal the connecting portion 9 that has passed through the insertion hole 10, and is housed in the flat pocket portion 8 to improve the stability of the cover. The stopper is also prevented from deforming, and the appearance is very clean. The specific value of the pocket depth p2 is determined in consideration of the above in addition to the condition of the pocket depth p1 on the front cover side, and is about one third to two thirds of the cover width b3. The range is a practical value.

FIG. 4 shows a state after mounting. FIG. 5 shows another embodiment. In the above description, returning to FIG. 1, the case where the connecting portion 9 is inserted into the insertion hole 10 is replaced with the previous arrow 11 and incorporated in the direction indicated by the arrow 16. Show. The main body A portion 1 and the main body B portion 2 do not have to be made of the same material and color, and the main body B portion 2 can be shown in FIG. However, in this case, the stoper does not fit in the pocket, and a part of the effect cannot be expected. Further, FIG. 6 shows another embodiment in which the connecting portion 9 is cut into a plurality of parts and the design is changed slightly, but the description is omitted.
