Description

Detailed description of the invention

The present invention relates to a book stopper for holding a book page in an open state, and more particularly to a book stopper having a large page pressing effect, can be used stably, is easy to manufacture, and also serves as a bookmark.

In the present specification and claims, a "book" is not limited to a book bound into a book such as a book or a paperback book, a paper, a magazine, a catalog, a pamphlet, etc., for example, a plurality of documents. It also includes unbound files such as loose-leaf and removable files on the binder.

Various types of page retainers (book stoppers) for holding the pages of a book in an open state are known. For example, the page holder described in Patent Document 1 also serves as a bookmark, and a main body made of transparent plastic (acrylic resin, etc.) that presses the page from above, a resin lower part that presses the cover from below, and both. It is composed of each member of the leaf spring, which connects the members.

However, this page holder uses a leaf spring to hold the page with a transparent acrylic resin plate by its urging force. That is, it is necessary to use a metal such as stainless steel for the leaf spring and a resin such as transparent plastic for the holding plate, which limits the material of the parts. In addition, parts made of these materials are not inexpensive and costly as products.

Further, the book holder described in Patent Document 2 is an integral configuration of a spiral or U-shaped grip portion and a pressing portion linearly extending from the grip portion. This book holder is attached so that the pressing portion is located on the opposite side of the seam, sandwiching several pages of the book opened by the grip portion. Then, the page on the opposite side is pressed by the pressing portion to keep the book open.

However, this book holder has an asymmetric structure in which the grip portion and the pressing portion are one each. Then, one side of the opened book is sandwiched by the gripping portion, and only the page on the other side is pressed by the pressing portion for use. In such a structure, the force applied to the left and right becomes non-uniform, and in order to suppress the force to close the page with only one pressing portion, the pressing portion is made of a thick and strong rigid material such as resin or metal. There is a need.

Further, although this book holder is held by sandwiching several pages on one side that are opened by a gripping portion, there is a limit to the thickness that can be sandwiched. For this reason, it is necessary to reattach the grip portion every time the number of pages sandwiched by reading a book exceeds the limit, resulting in poor operability. Further, since the grip portion has a spiral shape, the actual method for manufacturing as an integral product is not clear, and there is a problem that the manufacturing is practically difficult or the process is complicated even if it is possible. ..

In the book stopper according to the present invention, a main body portion having a page holding portion that can be opened and closed to the left and right is attached to the book by a supporting portion, and the page pressing portion is expanded by pulling the main body portion with a tension member to expand the page. The left and right of the opened part are pressed. Then, by mooring the tension member to the book at the mooring portion, the state in which the page is held down is maintained.

In one embodiment of the book stopper according to the present invention, the main body portion is provided with a pair of left and right page pressing portions as page pressing portions that can be opened and closed left and right. These pair of page holding portions have a symmetrical shape. Here, since the page holding portion is expanded to the left and right to hold the page of the open portion of the book, it may be opened and closed to the left and right, and may be not limited to a pair but may be two or more pairs. Further, the left and right numbers of the page pressing portions may be different, such as having one page pressing portion on the left side and two page pressing portions on the right side. Further, the page holding portion does not necessarily have to have a symmetrical shape, and the left and right shapes and sizes may be different.

In one embodiment of the book stopper, the support portion that supports the main body portion has a pair of strip-shaped holding portions, and these holding portions are on the left and right of the opened portion of the page and the page other than the opened portion. It is attached to a book by being sandwiched between pages or between the cover and pages. Here, the number of sandwiching portions constituting the support portion is not limited to one pair, and may be two or more pairs, and the numbers on the left and right may be different, such as having one sandwiching portion on the left side and two sandwiching portions on the right side. The shape of the sandwiching portion may be any shape other than the strip shape or the rectangle, and the left and right sandwiching portions may have different shapes or different sizes.

Further, in another embodiment of the book stopper, the support portion is a book cover attached to the book. That is, the main body portion provided with the page holding portion that can be opened and closed from side to side has a configuration integrated with the book cover. As an integrated configuration, the main body may be formed integrally with the book cover from the beginning, or the main body and the book cover may be manufactured separately and the main body may be attached to the book cover. Further, the separately manufactured main body and the book cover may be adhered and integrated.

As a configuration for attaching the main body to the book cover, there are a method of using an attachment member, a method of sandwiching the main body in the book cover, and the like. As the mounting member, for example, there is a method in which a book cover is sandwiched between one or more clips fixed to the main body using a clip. Further, a method may be adopted in which the magic tape is fixed to the lower end of the main body and the upper end of the book cover by using the magic tape (registered trademark), and these magic tapes are joined to each other.

It is more preferable that these mounting members are symmetrically fixed to the main body and the book cover. For example, three clips are fixed to the lower center of the main body and one to the left and right, and four clips are fixed to the left and right of the lower end of the main body. When using the Velcro (registered trademark) as a mounting member, fix it so that it has the same length from the center of the lower end of the main body and the center of the upper end of the book cover to the left and right. As a result, the force with which the main body is attached to the book cover becomes equal on the left and right, and the main body can be attached more firmly.

Further, as a method of sandwiching the main body portion between the book covers, there is a method of making cuts on the left and right sides of the main body portion and inserting the portion below the cut into the sleeves provided on the left and right sides of the book cover to insert the book cover. If the method of attaching the book cover to the book cover is other than the sleeve, or if the shape of the part to which the book cover is attached is different, the position and length of the notch may be changed according to the shape.

Further, as a method of adhering and integrating the main body and the book cover, an adhesive may be used, or the main body and the book cover may be made of synthetic resin and bonded by heat fusion.

In this way, a method of attaching the separately manufactured main body and the book cover using a clip or magic tape (registered trademark), a method of inserting the main body into a part of the book cover and attaching it, an adhesive or heat fusion When the method of adhering by means of is used, a commercially available book cover can be used as a support portion.

In one embodiment of the book stopper according to the present invention, the main body portion and the support portion are integrally formed of a bendable sheet-like material. The foldable sheet-like material is preferably a material having a certain degree of plastic deformability and maintaining its shape after being bent. As such a sheet-like material, for example, a paper material such as origami or thick paper can be used. Alternatively, in addition to the paper material, a synthetic resin (plastic) plate or a synthetic resin sheet having plastic deformability can also be used.

Further, as will be described later, when the page holding portion of the main body portion is reinforced with a reinforcing material having high strength, a soft material having low shape retention can be used as the sheet-like material. By using a highly flexible material with low shape retention, the main body can be easily manufactured, and the page holding portion can be freely bent with respect to the support portion. Examples of such flexible materials include cloth materials such as woven and knitted fabrics and non-woven fabrics, and flexible plastic films.

Further, in another embodiment of the book stopper, not only the main body portion and the support portion but also the tension member is integrally formed. When the tension member and the mooring portion are integrated, the entire book stopper is integrally formed. In this embodiment, since the book stopper or the material for producing the book stopper can be integrally manufactured from one material, it is suitable for mass production.

In one embodiment of the book stopper, the main body and the support are integrally formed of thick paper as a sheet-like material. In this embodiment, the main body and the support are integrally cut out from the thick paper along a predetermined contour, and a part of the main body is bent to form a page holding portion that can be opened and closed to the left and right. That is, the main body portion cut out from the flat thick paper becomes a page pressing portion having a three-dimensional structure by bending. In this way, the book stopper can be easily produced from thick paper, which is an inexpensive material.

In another embodiment, a patterned origami paper is used as a sheet-like material, and a main body portion and a support portion having a predetermined shape are integrally cut out from the origami paper and bent to form a three-dimensional page holding portion. In this embodiment, a book stopper is easily produced from origami, which is an inexpensive material, and the pattern and color of the origami are applied to the entire surface. As a result, it becomes a book stopper with high commercial value, which is not only easy to manufacture but also has an aesthetically pleasing and excellent design.

In one embodiment of the book stopper according to the present invention, the page holding portion is reinforced with a reinforcing material having a higher strength than the portion of the main body other than the page holding portion, or further compared with the supporting portion. ing. As a result, the page holding portion firmly holds the open portion of the book, so that the book stopper has an excellent page holding effect. Here, as the reinforcing material having high strength, thick paper having a thickness and hardness larger than that of ordinary thick paper, a plastic plate (synthetic resin plate), a metal plate, or the like can be used.

As a method of reinforcement, when the material of the main body has a certain degree of shape retention such as thick paper, origami, or a plastic plate, there is a method of adhering the reinforcing material to the front surface or the back surface of the page holding portion of the main body. When the material of the main body is a thin and soft material such as cloth or flexible plastic film, in addition to the method of adhering the reinforcing material to the front or back surface, the method of wrapping and fixing the reinforcing material with two flexible materials It can also be done by. Specifically, in the case of a cloth material, a reinforcing material placed on the page holding portion is sandwiched between two pieces of cloth, and the periphery is sewn with sewing thread to fix the material. In the case of a flexible plastic film, a reinforcing material placed on the page holding portion is sandwiched between two films, and the surrounding films are heat-sealed and fixed.

The page holding portion of the book stopper according to the present invention can be of any size and shape depending on the intended use. When used for a large-sized book or a thick book with a large number of pages, it is preferable to increase the area of the page pressing portion to increase the pressing force. However, when the page pressing portion is reinforced with a high-strength material as described above, the area of the page pressing portion can be suppressed to a small size. In order to prevent the opened part of the book from being hidden by the page holding part and becoming difficult to read, it is preferable to make the page holding part as small as possible. From this viewpoint as well, it is preferable to reinforce the page pressing portion with a reinforcing material made of a high-strength material as described above to secure a large pressing force with the small page pressing portion.

In one embodiment of the book stopper according to the present invention, the page holding portion is made of a transparent material. As the transparent material, a plastic plate or a sheet made of a transparent synthetic resin is used. Examples of the transparent synthetic resin material include various synthetic resins such as acrylic resin, polyethylene resin, polypropylene resin, polycarbonate resin, and polyvinyl chloride resin. When the page holding portion is made of a transparent material, it is preferable that the entire main body portion and the supporting portion are also made of the same transparent material. Further, when the support portion is a book cover as described above, it is preferable to use a transparent vinyl chloride resin or the like, which is widely used as a material for the book cover, as a material for the page holding portion and the entire main body portion.

Hereinafter, examples of the book stopper and the material for producing the book stopper according to the present invention will be described in detail with reference to the drawings. It should be noted that these examples are for more specific explanation of the present invention, and the scope of the present invention is not limited to the contents described in the following examples.

First, a first embodiment of the book stopper according to the present invention will be described with reference to FIGS. 1 to 6.

FIG. 1 is a perspective view showing the overall configuration of the book stopper according to the first embodiment of the present invention. As shown in FIG. 1, the book stopper 10 of the first embodiment has a main body portion 11, a support portion 13, a tension member 14, and a mooring portion 15. The main body portion 11 and the support portion 13 are integrally formed of thick paper, which is a paper material, and the main body portion 11 includes a pair of left and right page pressing portions 12A and 12B.

In order to manufacture the main body portion 11 and the support portion 13 integrally formed in this way, thick paper cut out along the contours of the main body portion 11 and the support portion 13 is used as a manufacturing material. Folding lines 11b, 11c, 11d, 11e, 11f, 13c, and 13d are drawn on the surface of the manufacturing material. As will be described later, the main body 11 is three-dimensionally manufactured by bending the manufacturing material along these folding lines. The outer shell of the material for production and the pentagonal portion surrounded by the folding lines 11e, 11f, 13c, and 13d form the page holding portions 12A and 12B.

The tension member 14 is, for example, a string-shaped member in which a plurality of synthetic fibers are bundled. One end thereof is fixed to the tip end 11a of the main body portion 11, and the other end thereof is taken out to the front surface through two through holes 12c and 12d provided in the main body portion 11. In the book stopper 10 of the first embodiment, the tip portion of the string-shaped member constituting the tension member 14 serves as the mooring portion 15 as it is.

The support portion 13 integrally formed with the main body portion 11 is composed of a pair of strip-shaped grip portions 13A and 13B. At the stage of manufacturing the book stopper 10, a plurality of folds are made along the plurality of fold lines 13c and 13d that partition the main body portion 11 and the support portion 13. As a result, the main body 11 of the book stopper 10 is flexible with respect to the support 13 toward the front side in FIG.

As shown in FIG. 1, the book stopper 10 configured in this way sandwiches the grip portions 13A and 13B between the left and right pages BL and the pages below the BR where the pages of the book B0 are opened. As a result, it can be attached to the book B0. Then, when the tension member 14 is pulled downward in FIG. 1, the main body portion 11 is bent, and the left and right page BLs and BRs are pressed by the page pressing portions 12A and 12B. While pulling the tension member 14, the mooring portion 15 which is the tip portion of the tension member 14 is made to bite into the lower end of the BC where the page of the book B0 is opened and moored, so that the page of the book B0 is kept open. can do.

Next, a manufacturing material for manufacturing the book stopper 10 according to the first embodiment will be described with reference to FIG. FIG. 2A is a plan view showing a material for manufacturing the book stopper 10 according to the first embodiment, and FIG. 2B is a bottom view showing a part of the bottom surface of the material for manufacturing.

As shown in FIG. 2A, the material 110 for manufacturing the book stopper of the first embodiment is composed of a plate-shaped material 110A and a string-shaped material 110B serving as a tension member 14 and a mooring portion 15. The plate-shaped material 110A includes a portion 111 that constitutes a main body portion having a pentagonal contour, and a portion 113 that constitutes a support portion having a pair of grip portions 113A and 113B. In this way, in the manufacturing material 110, the plate-shaped material 110A and the string-shaped material 110B are separately formed, but as shown in Examples 2 and 3 described later, the plate-shaped material and the tension member are integrated. It can also be formed into.

Folding lines 11b, 11c, 11d, 11e, 11f, 13c, and 13d are drawn on the surface of the plate-shaped material 110A. The folding lines 11c, 11d, 11e, and 11f indicated by the broken lines are mountain fold lines, and the folding lines 11b, 13c, and 13d indicated by the alternate long and short dash lines are valley fold lines. Further, the plate-shaped material 110A is provided with two through holes 12c and 12d for passing the tension member 14 which is the string-shaped material 110B.

Further, as shown in FIG. 2B, fold lines 11b, 11c, 11d, 11e, 11f, 13c, 13d corresponding to the front surface are drawn on the back surface of the plate-shaped material 110A. As a matter of course, on the back surface, contrary to the front surface, the fold lines 11c, 11d, 11e and 11f are indicated by dashed lines as valley fold lines, and the fold lines 11b, 13c and 13d are indicated by broken lines as mountain fold lines. The fold lines on the back surface in FIG. 2B do not necessarily have to be drawn.

Here, the plate-shaped material 110A is made of thick paper, and does not bend freely even in a place where there is no crease such as thin paper or cloth. Therefore, as shown in FIGS. 2A and 2B, a plurality of folds along a plurality of fold lines 13c and 13d are formed between the portion 111 constituting the main body portion and the portion 113 constituting the support portion. The eyes are attached. As a result, as shown in FIG. 1, the main body portion 11 is attached to the portion where the page of the book B0 is opened, regardless of the number and thickness of the support portion 13 sandwiched between the pages. It can be freely bent with respect to the support portion 13.

Next, the procedure for manufacturing the book stopper 10 according to the first embodiment will be described with reference to FIGS. 3 and 4. 3 and 4 are explanatory views showing a method of assembling the book stopper 10 according to the first embodiment from the manufacturing material 110.

As shown in FIG. 3A, first, the string-shaped material constituting the tension member 14 is fixed to the tip 11a of the plate-shaped material 110A. The fixing method may be any method as long as it can be firmly fixed so as not to come off when a tensile force is applied to the tension member 14. In the first embodiment, since the plate-shaped material 110A is thick paper and the tension member 14 is a string made of synthetic fiber, various methods can be used. For example, one end of the tension member 14 is adhered to the tip 11a with an adhesive or an adhesive tape, the adhesive portion between the tension member 14 and the tip 11a is covered with an adhesive or an adhesive tape from the periphery and fixed, and a hole is made near the tip 11a. There are methods such as connecting the ends of the tension member 14 together.

Next, as shown in FIG. 3B, the plate-shaped material 110A is folded along the folding lines 11b, 11c, 11d, 11e, 11f, 13c, and 13d. That is, when viewed from the front side, the folding lines 11c, 11d, 11e, and 11f are mountain-folded, and the folding lines 11b, 13c, and 13d are valley-folded. As a result, the portion 111 constituting the main body of the plate-shaped material 110A is bent into a three-dimensional structure as shown in FIG.

Next, as shown in FIGS. 4A and 4B, the tension member 14 fixed to the tip 11a of the plate-shaped material 110A is passed between the pair of gripping portions 113A and 113B, and then 2 The two through holes 12c and 12d are passed through. By fixing the tension member 14 to the tip 11a and passing the two through holes 12c and 12d in this way, when the tension member 14 is pulled, the page holding portions 12A and 12B are in close contact with the surfaces of the left and right pages opened. To do.

For the purpose of pressing the left and right pages with the page pressing portions 12A and 12B, the tension member 14 may be directly connected to the position corresponding to the through hole 12c without passing through the through holes 12c and 12d. In this case, the portion of the main body above the folding lines 11e and 11f, including the tip 11a, becomes unnecessary. That is, the plate-shaped material is produced by cutting out thick paper or the like along the outer shell having the folding lines 11e and 11f at the upper ends.

On the other hand, the book stopper 10 of the first embodiment is characterized in that the tension member 14 is fixed to the tip 11a and the folding line 11b connected to the tip 11a is valley-folded. As a result, when the tension member 14 is pulled, the center lines of the page pressing portions 12A and 12B are pushed by the valley fold of the folding line 11b, and the tension member 14 protrudes toward the binding of the book. That is, the lower surfaces of the page holding portions 12A and 12B have a shape along the surfaces of the left and right opened pages. Therefore, the page pressing portions 12A and 12B can be brought into close contact with the surfaces of the left and right pages that have been opened, and can be pressed more reliably.

A method of using the book stopper 10 according to the first embodiment produced in this manner will be described with reference to FIGS. 5 and 6. 5 and 6 are views for explaining how to use the book stopper 10 according to the first embodiment.

As shown in FIG. 5A, first, the left and right grip portions 13A of the book stopper 10 are located between the pages below the left and right pages BL and BR of the location BC where the page of the book B0 is opened. , 13B is sandwiched. As a result, the book stopper 10 is attached to the book B0 by the support portion 13.

Next, as shown in FIG. 5B, the tension member 14 is pulled downward in the drawing. Then, the main body portion 11 bends with respect to the support portion 13, and the page pressing portions 12A and 12B press the left and right page BLs and BRs that have been opened.

Then, as shown in FIG. 6A, the mooring portion 15 is made to bite into the lower end of the portion BC where the page is opened while pulling the tension member 14. As a result, the tension member 14 is moored at the lower end of the BC where the page is opened by the mooring portion 15 while holding the tensile force. Therefore, the pressing force for pressing the left and right page BLs and BRs opened by the page pressing portions 12A and 12B is maintained. By using the book stopper 10 according to the first embodiment in this way, it is possible to keep the page of the book B0 open.

When performing work such as taking a note by taking a hand off the page with the book B0 open, the book stopper 10 may be used in this way to keep the page of the book B0 open. Further, when closing the book B0 in the middle, if the mooring portion 15 is removed and the tension member 14 is loosened, the page holding portions 12A and 12B and the entire main body portion 11 can be closed. As a result, the book stopper 10 can be used as a bookmark.

Further, when reading the book B0, as shown in FIG. 6B, once the mooring portion 15 is removed, the tension member 14 is loosened, and the main body portion 11 of the book stopper 10 is lifted to display the next page B1. You can repeat it. By using the book stopper 10 in this way, it is possible to read the book B0 without any trouble while keeping the page open. As described above, the book stopper 10 according to the first embodiment can not only surely keep the page open, but also has excellent operability.

In the first embodiment, the tip portion of the tension member 14 is used as the mooring portion 15 to bite into the lower end of the BC where the page is opened, and the frictional force of the string-like material constituting the tension member 14 causes the book B0. It is locked. On the other hand, when the frictional force is insufficient due to the material and thickness of the string-like material constituting the tension member 14, for example, a knot can be tied at the tip portion of the tension member 14 to form the mooring portion 15. .. Further, the mooring portion 15 may be formed by wrapping a rubber band or the like around the tip portion of the tension member 14.

Next, a second embodiment of the book stopper according to the present invention will be described with reference to FIG. 7. FIG. 7 is a plan view showing a material for producing a book stopper according to a second embodiment of the present invention.
