Description

  The present invention relates to a universal cover for books, and more particularly, to an improvement of the invention "universal cover for books" disclosed in Japanese Patent Application No. 8-112049 by the present applicant.

  The universal cover of the present invention is composed of a pair of cover pieces. In this specification, an end portion where these cover pieces are assembled to each other is referred to as an “engagement end”, and the direction in which the cover pieces are assembled to each other is referred to as “engagement end”. The direction perpendicular to this is called “width direction”. Regarding the cover, “inside” means the side in contact with the book, and the opposite side is called “outside”.

  In the case of a newly published book, it is generally sold with a decorative cover from the publisher. However, in the case of secondhand books and collections, there is no such cover, so readers make their own covers with appropriate paper and carry them with them.

  By the way, there are books with various dimensional standards such as a library version, a books version, and a general book, but the thickness varies depending on the number of pages even with the same dimensional standard. Therefore, a conventional paper cover made by the conventional method is troublesome because it is necessary to make a separate cover for each thickness.

  The above-mentioned invention of the prior application has been proposed to cope with such a problem.

  The cover of the prior application has a pair of cover pieces, and is constructed by assembling these pair of cover pieces in an overlapping state in the engaging direction.

Since the overall length in the engaging direction is adjusted by changing the degree of polymerization in the engaging portion, it is possible to mount the book on books of various thicknesses.

  However, in the case of the cover of the invention of the prior application, since the engaging portion is partially exposed to the outside of the cover, the engaging portion is likely to be worn and damaged by long-term use. Moreover, it is not preferable in appearance. Further, a book attached to the cover may be detached in the width direction of the cover while moving while being carried.

  In view of the disadvantages of the prior invention, an object of the present invention is to prevent the engagement portion from being worn or damaged and to prevent the attached book from being detached.

  For this reason, the free cover for a book according to the present invention comprises a pair of cover pieces, and the first cover piece is spaced apart from a substantially rectangular front cover portion, a central tongue portion protruding from the engagement end in the engagement direction, and both sides thereof. The second cover piece is composed of a substantially rectangular front cover portion and a central tongue portion projecting in the engaging direction from the engaging end thereof, and the second cover piece. The center tongue portion of the first cover piece is wider than the center tongue portion of the first cover piece, and a long hole is formed in the width direction thereof to pass through the center tongue portion of the first cover piece. The gist is that a cover piece extends in the width direction and is attached to the outside of one cover piece in the vicinity of the portion, and the holding piece protrudes from at least one end in the width direction of the cover piece.

  Since the cover covers the engaging part of the cover, there is no wear or damage to the engaging part, and the holding piece presses the cover of the book against the inside of the cover while the cover is attached to the book. Elimination of books is effectively prevented.

  The disassembled state of the universal cover of the present invention is shown in FIG. This cover is composed of first and second cover pieces 1 and 2. The dimensions in the engagement direction and the width direction of both cover pieces are appropriately set according to need, that is, according to the expected thickness change of the target book of the same size standard.

  The first cover piece 1 has a substantially rectangular cover 1 and a central tongue 12 protruding from the engagement end in the engagement direction. On both sides of the central tongue, a pair of side tongues 13 project in the engagement direction in parallel with the central tongue 12 with a gap 14 therebetween.

  The second cover piece 2 has a substantially square cover portion 21 and a central tongue portion 22 protruding from the engagement end in the engagement direction. The width of the central tongue 22 is preferably slightly larger than the width of the central tongue 12 of the first cover piece 1 and preferably slightly smaller than the interval between the side tongues 13 of the first cover piece 1. . A long hole 23 is formed in the base portion of the central tongue 22 so as to extend in the width direction. The length of the long hole 23 is set such that the central tongue 12 of the first cover piece 1 can be freely inserted.

  FIG. 2 shows a free cover in an assembled state. The central tongue portion 12 of the first cover piece 1 is located on the cover portion 21 through the long hole 23 from below the central tongue portion 22 of the second cover piece 2. Further, both side tongue portions 13 of the first cover piece 1 are positioned on the cover portion 21 of the second cover piece 2. Therefore, by changing the degree of insertion of the central tongue 12 of the first cover piece 1, the length of the entire cover in the engaging direction can be freely adjusted according to the thickness of the book to be mounted.

  In use, the book to be mounted is placed on the universal cover in the state shown in FIG. .

  What has been described above is the structure and method of use of the universal cover of the prior invention. Next, the present invention will be described with reference to FIG.

  As shown in FIG. 3, in the present invention, the cover piece 31 has a width on the outside of one cover piece (second cover piece 2 in the illustrated example) in the vicinity of the engaging portion 30 of both cover pieces 1 and 2. The holding piece 32 protrudes from one end in the width direction of the covering piece 31.

  Attachment of the cover piece 31 to the cover piece may be performed by sewing with a sewing machine or the like, or may be performed by sticking with an adhesive or the like. The holding piece 32 may be formed integrally with the cover piece 31, or may be formed separately and stitched to the cover piece 31 with a sewing machine or the like. Further, as shown in FIG. 4, a part of the covering piece 31 may be formed in an arc shape. Further, the holding piece 32 may protrude from both ends of the covering piece 31 in the width direction.

In use, after the cover is attached to the book as described above, the holding piece 32 is placed along the cover piece so as to cover the engaging portion 30 as indicated by an arrow in FIG. The cover piece 1 and the cover of the book to be mounted may be rolled up and bent inward. In this way, the engagement portions 30 of the cover pieces 1 and 2, that is, the side tongue pieces 13 of the cover pieces 1, the base end portions of the gaps 14, and both edges in the width direction of the central tongue piece 22 exposed from the gaps 14 are formed. Since it is covered with the covering piece 31 and is not exposed to the outside, the appearance is improved, and wear and breakage of the engaging portion can be prevented.

  The present invention can be widely used in fields such as the book industry.

It is a disassembled top view of the universal cover to which this invention is applied. It is an assembly perspective view similarly. It is a perspective view of a cover to which one embodiment of the present invention is applied. It is a top view which shows the other Example of this invention.
