Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible cover for books, and more particularly to improvement in dimensional versatility of a cover to be attached to books such as used books.

[0002]

2. Description of the Related Art As will be described in detail below, the universal cover of the present invention is composed of a pair of cover pieces. In this specification, the end portions where the cover pieces are assembled with each other are "engaged". The end is referred to, the direction in which they are assembled to each other is referred to as the "engagement direction," and the direction orthogonal to this is referred to as the "width direction."

In the case of newly published books, they are generally sold by publishers with a cover for decoration. However, in the case of used books and collections, there is no such cover, so the reader makes a cover of appropriate paper and wears it and carries it.

[0004]

However, there are various dimensional standards such as a library edition, a books edition, and a general book edition as a book, but the thickness is different depending on the number of pages even with the same dimensional standard. If the cover is made by hand as in the past, even if the same size standard is used, it is not possible to apply it to the same cover with different thickness. Therefore, it is necessary to make a separate cover for each thickness of the book, which is complicated. Also, in the case of a cover made of beautiful paper, even if the reader wanted to use this cover for various books, it was impossible because of the thickness limitation.

In view of the above situation, an object of the present invention is to improve dimensional versatility of a book cover.

[0006]

To this end, according to the present invention, a cover is composed of a pair of cover pieces, and the first cover piece projects from the substantially rectangular cover portion and its engaging end in the engaging direction. And a side tongue spaced apart from each other and projecting parallel to each other, the second cover piece has a substantially rectangular cover portion and a central tongue portion protruding from the engaging end in the engaging direction. The central tongue portion of the second cover piece is wider than the central tongue portion of the first cover piece, and a slot for inserting the central tongue portion of the first cover piece is formed in the width direction. The purpose is to set up.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION A central tongue portion of a first cover piece is a second cover piece.
One book cover is constructed by inserting both cover pieces into the long hole of the cover piece of
The length in the engagement direction can be freely adjusted by changing the degree of insertion described above.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An example of the universal cover of the present invention is shown in an exploded state in FIG. This cover is composed of first and first cover pieces 1 and 2. The length of both cover pieces in the engagement direction can be appropriately set as necessary.

The first cover piece 1 has a substantially rectangular cover sheet portion 11.
And a central tongue portion 12 protruding from the engaging end in the engaging direction. A pair of side tongues 12 project parallel to the central tongue 12 in the engaging direction with a gap 14 on both sides of the central tongue 12. The dimensions in the engaging direction and the width direction of each portion are appropriately set as necessary.

The second cover piece 2 has a substantially rectangular cover 21.
And a central tongue portion 22 projecting from the engaging end in the engaging direction. The width of the central tongue portion 22 is equal to that of the first cover piece 1.
It is preferable that the width is slightly larger than the width of the central tongue portion 12 and is slightly smaller than the distance between the both side tongue portions 13 of the first cover piece 1. A long hole 23 is formed in the base of the central tongue portion 22 so as to extend in the width direction. The length of the long hole 23 is such that the central tongue portion 12 of the first cover piece 1 can be freely inserted.

FIG. 2 shows the universal cover in the assembled state. The central tongue portion 12 of the first cover piece 1 is located above the cover sheet portion 21 through the elongated hole 23 from the lower side of the central tongue portion 22 of the second cover piece 2. Both side tongues 13 of the first cover piece 1 are located on the cover 21 of the second cover piece 2. Therefore, by changing the insertion degree of the central tongue portion 12 of the first cover piece 1, the length of the entire cover in the engagement direction can be freely adjusted as necessary.

In use, the target book may be placed on the universal cover in the state shown in FIG. 2, and the end portions 15 and 25 of both cover pieces 1 and 2 may be folded so as to be held on the book. .

In the above example, the central tongues are each substantially rectangular, but the invention is not limited to this. For example, the tip may be rounded. In the assembled state, the tongue portions on both sides of the first cover piece are the second cover piece 2.
The dimensional relationship may be such that it overlaps the central tongue portion 22 of.

In the case of the covers shown in FIGS. 1 and 2, the cover piece 1 and the cover piece 2 are easily separated. That is, while carrying a book with a cover,
This is inconvenient because the cover may fall off the book. A configuration for avoiding such an inconvenience is shown in FIGS.

In the first cover piece 1 of the embodiment shown in FIG. 3, the connecting portions 15 project inwardly from the engaging ends of the tongue portions 13 on both sides.

When assembling the two cover pieces 1 and 2, the central tongue portion 12 of the first cover piece 1 is inserted into the elongated hole 23 of the second cover piece 2 while being separated from the connecting portion 15. When the assembling is completed, both connecting portions 15 are joined to both sides of the central tongue portion 12 by, for example, suturing as shown by a dotted line in the figure. As a result, both cover pieces 1 and 2 are integrated and are not separated.

In the first cover piece 1 of the embodiment shown in FIG. 4, the tongue portions 13 on both sides are connected by the connecting portion 16 extending in the width direction at the engaging end.

When both cover pieces 1 and 2 are assembled, the central tongue portion 12 of the first cover piece 1 is inserted into the elongated hole 23 of the second cover piece 2 while being separated from the connecting portion 16. When the assembling is completed, the connecting portion 16 is joined to the engaging end of the central tongue portion 12 by, for example, suturing as shown by a dotted line in the figure. As a result, both cover pieces 1 and 2 are integrated and are not separated.

[0019]

Since the length in the engaging direction can be freely adjusted by changing the degree of insertion of the central tongue, one cover can be generally used for books of various thicknesses as long as dimensional standards are met. be able to.
