Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a book storage case for storing and storing books. In particular, the present invention relates to a case for storing a book, which is easy to store and take out the book, is less likely to damage the book, and is effective for long-term storage.

[0002]

[Prior art]

 In recent years, valuable books called rare books and rare books, such as historically valuable books and books, are extremely expensive, and when they are stored in a library, one by one is used to prevent damage and deterioration. It is stored and stored in.

[0003] For example, books with historical value such as Gutenberg's first edition, Marco Polo's eastern memoir, Aesop's story, Marx's theory of capital, Adam Smith's first wealth theory, etc. Moreover, since they are extremely expensive and traded, a storage case is required to store these books.

[0006] Several cases have been used as a case for storing such a book that has been conventionally used, and a typical case for storing a book will be described below with reference to FIGS. 10 to 14. To do.

FIG. 10 is a perspective view of an example of a conventional book storage case. An opening 101 is provided in a portion corresponding to the back cover of a book, and it is composed of a box-shaped sack-type case 100 usually made of cardboard, etc. The front side of the book is inserted into the opening 101 and the book is taken in and out. It is a method of doing. Generally used for storing Western books.

FIG. 11 is a perspective view of another example of a conventional book storage case. As shown in FIG. 11, a tray-shaped upper lid case portion 111 and a bottom lid case portion 115 having a size slightly smaller than that are joined to each other at joint portions 112 and 114 via a back plate 113 so as to be bendable. This is a case in which a book is stored in this case, the upper lid case portion 111 is covered on the bottom lid case portion 115, and the lid is closed for storage. This case is also commonly used to store Western books.

In the case of Japanese and Chinese books, a storage case called “帙” or “Tato” is used. FIG. 12 is a perspective view of the tato in the unfolded state, FIG. 13 is a perspective view showing a state in which the tato is partially folded to store a book, and FIG. 14 is a view for locking the tato lid to the bottom plate. FIG. 6 is a partially enlarged view showing a locked state of a claw and a sprue. An edge plate 126 is foldably joined to the left side of the bottom plate 121, and an inner lid plate 127 is foldably joined to the left side of the edge plate 126. Further, a back plate 123 is foldably joined to the right side of the bottom plate 121, and a front cover plate 122 is foldably joined to the right side of the back plate 123. Further, a top plate 124 and a bottom plate 125 are foldably joined to the upper side and the bottom side of the bottom plate 121, respectively. The top plate 124 and the bottom plate 125 respectively have a top plate locking plate 124a and a bottom plate engaging member. The stop plate 125a is foldably joined. A claw 128 is attached to the outer side surface of the front cover plate 122 with a string 129, and a claw 130 for locking the claw 128 is provided on the outer side surface of the bottom plate 121.

In order to store a book in such a "toto", place the book on the bottom plate 121, bend the top plate 124 and the base plate 125 inward, and make them stand up so as to be perpendicular to the bottom plate 121. Further, the top plate locking plate 124a and the base plate locking plate 125a are respectively bent to cover the book, and then the edge plate 126 is bent inward to stand up so as to be perpendicular to the bottom plate 121. The inner lid plate 127 is bent in a direction substantially perpendicular to the foremost plate 126. FIG. 12 shows just this state. Subsequently, the back plate 123 is bent inward to stand up so as to be perpendicular to the bottom plate 121, the front cover plate 122 is further bent and overlapped on the inner cover plate 127, and finally the claw 128 is provided on the outer surface of the bottom plate 121. By firmly inserting it into the cochle 130 and locking it, the inner cover plate 127 is tightened by the pressing force of the front cover plate 122, and the inner cover plate 127, the top plate locking plate 124a, and the main plate locking plate 125a. The top plate 124 and the base plate 125 are prevented from opening due to the weight of the book due to the frictional force between them.

[0009] The "帙" has a structure similar to that of the above-mentioned "Tato", but is different from the "Tato" in that the top plate 124, the base plate 125, and the top plate locking plate 124a and the base plate lock. The part corresponding to the plate 125a is lacking, so that the top and bottom of the book, that is, the top and bottom of the book, have no cover.

[0010]

[Problems to be solved by the device]

 In the case of the box-shaped sack-type case 100 as shown in FIG. 10, the structure is simple, but since the book is put in and taken out through the narrow opening 101, the cover is rubbed and the cover is easily damaged, let alone the historical. In addition, since the covers of old books are considerably damaged, using such a storage case will further damage the books. This tendency is especially noticeable in old books that use natural leather as the exterior material for the cover. Of course, in this type of case, you can't open the book to see the contents without removing the book from the case.

In the case of the case as shown in FIG. 11, there is not much problem when it is stored and stored, but due to the structure, the tray-like upper lid case portion 111 and slightly more than that. Since the bottom lid case portion 115 having a small size is joined via the back plate 113 at the joint portions 112 and 114 so as to be bendable and integrated, the top lid and the bottom lid are joined together like a so-called ordinary lunch box. It is difficult to open and close, unlike when they are separated from each other, and the thicker the book, the more difficult it is to open and close.To avoid this, if the size of the bottom lid is made quite small, the case can be opened easily. , The case may open if it is not squeezed from both sides during storage on the bookshelf. In addition, it is preferable to keep valuable books out of the case as much as possible, but in this case, it is quite difficult and impossible to open the books without removing them from the case with the case open. The problem is that if you try to turn a page, you risk damaging the book.

In the case of “Tatou” shown in FIGS. 12 to 14, since the locking mechanism is formed by the claw 128 and the sprue 130, this portion is projected to the outside, and a plurality of such cases are formed. If the items are stored next to each other in a library, the protruding part may be an obstacle, and in some cases this part may be rubbed or caught on the adjacent case. I find it inconvenient to handle it. In addition, when the book is taken in and out again, it is necessary to firmly insert the claw 128 into the spit 130, and this part is easily damaged. Also, the top plate locking plate 124a and the base plate locking plate 125a are quite large, and it is preferable that this part should not be provided originally, but when these cases are opened, they tend to fold inward unexpectedly. Open the book and put it on the case without removing it from the case, which hinders the spread of the book, making it difficult to read the book. There is also a risk that a page of a book will be caught by the covered top plate locking plate 124a and / or the base plate locking plate 125a and break the page. Moreover, since it has a tendency to fold and bends inward, it is inconvenient to browse the book while holding it so that it does not cover the book. In addition, when storing and storing, an extra volume of the bookshelf is required for the thickness of the top plate locking plate 124a and the base plate locking plate 125a, and if many of these are to be stored, the cost of the storage place will be the same as at present. This is a problem that cannot be ignored in the age when it takes a lot of time. Moreover, when the thickness of the stored books is smaller than the thickness of the case, there is a problem that the top plate locking plate 124a and the base plate locking plate 125a are easily pulled out.

Further, as described above, the “scroll” lacks a portion corresponding to the top plate 124 and the bottom plate 125 of the “tato”, and therefore, the top and bottom of the book, that is, the top and bottom of the book are not included. It is unsuitable for storage and storage because it has no cover.

The present invention solves the problems of the conventional case for storing a book, allows the book to be easily taken in and out, and can be securely stored, and is opened when the case is opened. It is an object of the present invention to provide a case for storing a book, which can be easily opened with a book placed on the storage case in this state and which is excellent in handling and storage.

[0015]

[Means for Solving the Problems]

 In order to achieve the above object, the book storage case of the present invention has the following structure.

(1) A lid plate and a bottom plate are joined to each other via a back plate so as to be bendable, and the upper side part, the left side part and the lower side part of the cover plate are respectively an upper side part side plate and a left side part side plate. And the bottom side plate is inwardly bendable and the top side, right side and bottom side of the bottom plate are inwardly bendable with the top side plate, right side plate and bottom side plate, respectively. The inner side surfaces of the upper side plate, the left side plate and the lower side plate of the lid plate, and the outer side surfaces of the upper side plate, the right side plate and the lower side plate of the bottom plate. A book storage case in which magnets are stacked.

(3) The magnet is a sheet-like magnet sheet, and the magnet sheet is a magnet sheet in which a plurality of magnet portions and non-magnet portions are alternately arranged in a striped shape in the longitudinal direction of the magnet sheet. The case for storing a book according to any one of (2).

(4) A cover plate, a bottom plate, a back plate, and an upper side plate, a left side plate and a lower side plate of the cover plate, and an upper side plate, a right side plate and a lower side plate of the bottom plate. The book storage case according to any one of (1) to (3) above, wherein the main material of the book is neutral paper.

[0019]

[Action]

 In the case for storing books according to the present invention described in the item (1), the lid plate and the bottom plate are foldably joined to each other through the back plate, and the upper side portion, the left side portion and the lower side portion of the lid plate are connected to each other. , The upper side plate, the left side plate, and the lower side plate are connected so as to be bent inward, and the upper side, the right side, and the lower side of the bottom plate are respectively connected to the upper side plate, the right side plate, and the right side plate. The lower side plate is joined to the inside so as to be bendable, and the inner side of each of the upper side plate, the left side plate and the lower side plate of the lid plate, and the upper side plate of the bottom plate, Magnets are laminated on the outer surface sides of the right side plate and the lower side plate, respectively, so when this case is opened, it becomes one integrated sheet, and the book is removed from the case. You can easily write it on the case without removing it. It is possible to browse. Also, when the case is closed, it can be easily and firmly closed by the magnet, and it is extremely easy to assemble the case, and it does not take much time, and moreover, even when the case is assembled, compared to the conventional one. It has the same or greater strength and is extremely easy to open. Moreover, there is no particular protrusion on the outer surface of the lid plate or the bottom plate, and the storage rate in the bookshelf is not reduced.

Further, as described in the above item (2), a preferred embodiment of the present invention is such that the upper side plate, the left side plate and the lower side plate of the lid plate are provided with notches, respectively. Therefore, it is preferable that the presence of these notches makes it easier to open by opening the case by placing a finger on these notches.

Further, as described in the above item (3), the magnet is a sheet-shaped magnet sheet, and a plurality of magnet portions and non-magnet portions are alternately arranged in stripes in the longitudinal direction of the magnet sheet. According to a preferred embodiment of the present invention, which is an array of magnet sheets, when the case is closed, the side surfaces of the side plates on which the magnets are laminated face each other, and the side plates face each other due to the magnetic force of the mutual magnets. Although they are firmly connected to each other, this is a magnet sheet in which multiple magnet parts and non-magnet parts are arranged alternately in a striped shape, so all the magnets of the facing side plates come to a position where they overlap each other. At this time, the coupling force of the facing side plates suddenly becomes strong, so even if the position of the facing side plates is misaligned, it can be easily corrected and excessive force is required to correct it to the correct position. This is not preferable, and it is possible to give the property of easily reaching the correct position, which is preferable. That is, when a sheet-shaped magnet whose entire surface is a magnet is used, even if the positions of the side plates facing each other are deviated, the mutual coupling force is relatively strong. Compared to the case where it is necessary, it is more difficult to correct the position and it is more preferable that the above-mentioned action is exhibited, compared to the case where it is not particularly easy to arrange in the correct position and the positions facing each other. .

Further, as described in the item (4), the lid plate, the bottom plate, the back plate, the upper side plate of the lid plate, the left side plate and the lower side plate, and the upper side plate of the bottom plate. The preferred embodiment of the present invention, in which the main material forming the right side plate and the lower side plate is neutral paper, makes the stored books terrible when exposed to an acidic environment. However, it is preferable to use neutral paper as the main member used in the present invention, because it can be used as a safe storage case for long-term storage of books.

[0023]

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a plan view of the book storage case according to an embodiment of the present invention seen from the inner side surface of the case, FIG. 2 is a perspective view of the case during assembling, and FIG. 3 shows the case assembled. 3 is a perspective view of the case in a closed and closed state, FIG. 4 is a plan view of the case of FIG. 3 viewed from the direction of arrow A in FIG. 3, and FIG. 5 is a view of the case of FIG. 3 viewed from the direction of arrow C of FIG. FIG. 6 is a plan view of the case of FIG. 3 seen from the direction of arrow B in FIG. 3, and FIG. 7 is a cross-sectional view of the case of the present invention in the same direction as the DD ′ direction cross section of FIG. It is a sectional view of one mode.

First, a description will be given below mainly with reference to FIGS. 1 to 6 of the present invention, a lid plate 1 and a bottom plate 21 are foldably joined to each other at bending portions 12 and 28 via a back plate 30, respectively. An upper side part side plate 2, a left side part side plate 5 and a lower side part side plate 9 are respectively joined to the upper side part, the left side part and the lower side part so as to be bendable inwardly at bending parts 3, 6 and 10, respectively. Similarly, on the upper side, the right side and the lower side of the bottom plate 21, the upper side side plate 22, the right side side plate 24 and the lower side side plate 26 can be bent inward at the bending portions 23, 25 and 27, respectively. It is joined.

Further, the inner side surfaces of the upper side plate 2, the left side plate 5 and the lower side plate 9 of the cover plate 1 (ie, corresponding to the front side of the paper surface of FIG. 1 in FIG. 1). On the outer side of the upper side plate 22, the right side plate 24, and the lower side plate 26 of the bottom plate 21 (that is, the back side of the plane of FIG. 1 in FIG. 1), respectively. (Not shown) are stacked. That is, referring to FIG. 7, the magnet 48 is laminated on the upper side of the board 41 which is the main constituent material of the left side plate 5 and the lower side of the board 44 which is the main constituent material of the right side plate 24. A magnet 49 is laminated on the.

In the example of this case, as can be seen from FIGS. 2, 3 and 6, the back plate 30 has a slightly convex rounded shape on the outside of the case, which allows the back plate 30 and the upper side plate to be rounded. Since a slight gap is opened between the case and the bookcase, even when the bookcase is being healed along with other books, put your finger on the end of the backboard 30 on the side of the upper side board 2 to easily open the case. It can also be easily pulled out from the bookshelf. Of course, the back plate 30 does not necessarily have to have a slightly convex roundness and protrudes to the outside of the case, and may have a flat shape.

Further, in this example, an end of the upper side plate 2 of the lid plate 1 in the direction opposite to the back plate 30 is cut out, and a cutout 4 is formed. Notches 7 and 8 are formed at both ends of the side plate 5, and a notch 11 is formed at an end of the lower side plate 9 opposite to the back plate 30. Therefore, as is clear from FIGS. 4 and 6, when opening a case that is assembled and closed, it is easier to catch a finger on the cutout and open the case more easily than when there is no cutout. I like it. It is easily understood that the shape of the cutout portion is not necessarily limited to the illustrated shape.

Further, in this example, as shown in FIGS. 2 to 4, a tape-shaped knob 29 is provided on the outer surface of the left side plate 5 of the lid plate 1. When the case is opened, this knob 29 can be pulled and opened, which is preferable. The knob 29 does not necessarily have to be provided, but when it is provided, a flexible material such as a tape or a string-like material is preferable because it does not hinder the storage of the bookcase.

Further, as is apparent from FIG. 3, in this example, a shallow recess 31 is provided on the outer surface of the lid plate 1. Similarly, as is apparent from FIG. 5, the outer surface of the back plate 30 is also formed. A shallow depression 32 is provided on the bottom surface of the book, and if necessary, a label on which the title of the book is written may be attached, or the title of the book may be directly written by foil stamping or the like.

FIG. 7 shows a more detailed cross-sectional view of one embodiment of the book storage case of the present invention in the same direction as the cross section in the DD ′ direction of FIG. FIG. 2 is a diagram for explaining one aspect of a laminated structure of a core material such as a board, an interior material, an exterior material, and a magnet, which are not clearly shown in FIG. 1.

A board 41 is provided as a core material of the left side plate 5 of the lid plate 1, and a magnet 48 is laminated along the upper surface of the board 41. The lid plate 1 also uses the board 42 as a core material, and the core board 60 of the back plate 30 is a slightly thinner board. Similarly, the bottom plate 21 also uses the board 43 as the core material, the right side plate 24 also uses the board 44 as the core material, and the magnet 49 is laminated on the lower surface of the board 44. A flexible sheet-like exterior material 45 is attached to the outer surface of each board in order to connect each of these core materials and to make the appearance beautiful, and the exterior material 45 is partially folded. As shown in the exterior materials 45a and 45b, they reach a part of the inner side surface, thereby forming the bent portions 6, 12, 28 and 25, respectively. Further, a flexible sheet-like reinforcing sheet 46 is attached to the inner side surface of the core board 60 of the back plate 30 over a part of the inner side surfaces of the board 42 of the lid plate 1 and the board 43 of the bottom plate 21. , The bent portions 12 and 28 are reinforced. Further, in this example, the interior material 47 is attached to the inner surface of the case. Although the cross-sectional view is not shown, the upper side plate 2, the lower side plate 9 and the bent parts 3, 10 and the upper side plate 22, the lower side plate 26 and the bent parts 23, 27 also have substantially the same sectional structure. ing.

Examples of the board material include cardboard, a plastic plate, a veneer plate, and an aluminum plate. Among them, neutral paper (pH of about 7 to 8.5) is preferably used. , It is preferable because it can prevent the books from being damaged by the acid and becoming tattered. The thickness of these boards is not particularly limited, and may be selected in consideration of the strength according to the type of material, the site to be used, and the purpose. Usually, a board having a thickness of about 1 to 4 mm is used. .

Also, for the exterior material 45, the interior material 47, and the reinforcing sheet 46, suitable materials may be selected according to the purpose, and for example, paper, plastic sheet, natural leather, synthetic leather, cloth, etc. are representative. Target. In particular, as the interior material, synthetic leather or napped fabric having a nap, represented by "Exeine" of Toray Industries, Inc., is preferable because it rarely damages the books because it gently hits valuable books. .

A sheet-shaped magnet is preferably used as the magnet and is not particularly limited, but the thickness of the magnet is preferably about 0.3 to 3 mm, and its perspective view is shown in FIG. As shown, a magnet sheet in which a plurality of magnet portions 50 and non-magnet portions 51 (for example, rubbers) are alternately arranged in a stripe shape in the longitudinal direction is preferably used for the reason described above. Such magnets are commercially available as, for example, "Magnet Sheet" manufactured by Nichirei Magnet Co., Ltd. and are easily available. Although not particularly limited, an anisotropic magnet sheet is preferable because it has a stronger magnetic force. When such striped magnets are laminated on each side plate, they are laminated so that the longitudinal direction of the stripes coincides with the longitudinal direction of each side plate.

Although the magnet may be exposed and laminated at the above-mentioned portion, it may be covered with an exterior material or an interior material as shown in FIG. 7 from the appearance. FIG. 9 shows a schematic cross-sectional view of a part of a case where such a strip-shaped magnet sheet is applied and the magnets facing each other close the case by magnetic force.

FIG. 9 is a schematic partial cross-sectional view showing a state in which the left side side plate 5 of the lid plate 1 and the right side side plate 24 of the bottom plate 21 of FIG. 7 are overlapped with each other, and the case is assembled and closed. The exterior and interior materials are indicated by dotted lines, omitting detailed description.

As described above, since a plurality of magnet portions 50 and non-magnet portions 51 are alternately arranged in a stripe shape, the stripe shape of the magnet sheets 48 and 49 of the side plates 5 and 24 facing each other is formed. When all of the magnet portions 50 of the side plates come to overlap each other, the coupling force of the facing side plates (left side side plate 5, right side side plate 24) suddenly becomes strong. Even if there is a deviation, it is preferable because it can be easily corrected, it does not require too much force when facing each other at the correct position, and the property that it can easily go to the correct position can be imparted.

As is clear from FIGS. 1 to 3, when the book storage case is assembled to store the book, the book is placed on the bottom plate 21, and the upper side plate 22 and the right side plate are placed. The side plate 24 and the lower side plate 26 are bent inwardly at the bent portions 23, 25, and 27 substantially perpendicularly to the bottom plate 21, and the back plate 30 and the lid plate 1 are bent inwardly at the bent portions 28 and 12. Finally, the upper side plate 2, the left side plate 5 and the lower side plate 9 are respectively folded inward at the bent portions 3, 6 and 10 to form the bottom plate 21, the upper side plate 22, the right side plate 24 and the lower side part. Overlapping on the outer surface of the side plate 26, the overlapping side plates are coupled to each other by the action of the above-mentioned magnets, the case is closed, and the case assembly and the book storage are completed. When opening this case, it is sufficient to open it in the reverse order of the above.

As described above, and as can be seen from FIG. 3, the upper side plate 2, the left side plate 5 and the lower side plate 9 are respectively the upper side plate 22, the right side plate 24 and the lower side plate of the bottom plate 21. Therefore, the upper side plate 22, the right side plate 24, and the lower side plate 26 are attached to the bottom plate 21 slightly inward of the bottom plate 21. It is preferable that it is on the side, as it allows for a perfect overlay. It is needless to say that the back plate 30 shown in FIG. 1 may be used as a shaft and the left and right sides may be interchanged as needed.
