Abstract

(57) [Abstract] [Purpose] The purpose of the present invention is to provide a tool for securely opening a book on the table with one touch, and it is convenient for writing notes while looking at the book. Although it is to dramatically improve efficiency, detailed goals are to be portable and compact and lightweight, not to damage books and pages, and not to disturb the important characters you want to read. , It is cheap, etc. Since it does not damage books, it is expected to be used for displaying important books at various exhibitions. [Structure] A hard and thin plate that is sufficiently longer than the width of the book is attached to one end with a hairpin-type press for pinching the cover to the page you want to open. This is a book-opening tool that maximizes the weight of the book as the force to open the page by crossing at. If the material is transparent plastic, it is most desirable because it does not disturb the letters. It can also be used as a ruler if you add a scale.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The purpose of the present invention is to keep the book open on the table without any effort, so it is extremely lightweight and compact, which makes it convenient to carry and keep the book open. It contributes to dramatically improve the efficiency of writing and writing. It can also be used to display important books at various exhibitions, as there is no need to make unnecessary creases on books.

[0002]

[Prior art]

 In the past, books wouldn't stay open unless you held them open by hand or made a crease on the page fairly firmly. There is a so-called book stander that holds a book upright at an angle, but it is quite bulky.

[0003]

[Problems to be solved by the device]

 In the past, it was necessary to hold a hand or make an unreasonable crease, but it tries to make the book open even if the hand is released or there is no unreasonable crease. . It also aims to achieve portability by providing lightweight and compact products.

[0004]

[Means for Solving the Problems]

 A hairpin-shaped press that holds the thin and long thin plate of plastic, metal, etc., and the length of the plate is sufficiently longer than the width of the book, between the front and back covers of the book and the page you want to open. Use two boards with. First, open the page you want to open, and hold this tool on the sides of the book with the tool inside the book and the long board outside the book. Because the front and back cover of the book to the open page and the tool are fixed by pressing, respectively, and because the two long boards intersect at the bottom when the book is placed on the table. When the book is placed on the table, the weight of the book pushes it down in the direction that makes the board parallel to the table, and the force is used as the force to open the page through the board, keeping the book open.

[0005]

[Action]

 Insert the front and back cover of the book to the page you want to open with the hairpin type press so that the boards are on the front and back cover sides. At the back of the book, the two boards will cross each other, but in this state put the book on the table with the board down. The book pushes the plate down by its weight and the plate tries to be parallel to the table. The force at this time is greater than the force that tries to close the book, and when the book is opened, there is a balance. So the book is open. If the page you want to open is near the very beginning or the end of the book, keep one tool open.

[0006]

【Example】

 Hereinafter, an embodiment will be described with reference to the accompanying drawings. As shown in FIG. 1, a hairpin type presser 2 is processed and provided on one side of a thin plate 1 having a length sufficiently longer than the lateral width of a book to be used. The material used may be plastic or metal, the plate part should be rigid so as not to bend, and the pressing part should have an appropriate elasticity and size for sandwiching a book. The one used on the right side of the book and the one used on the left side have the same structure. Further, when transparent plastic is used as in claim 2, the presser does not obscure the characters. Moreover, if a scale is attached to the plate as in claim 3, it can be used as a ruler. It is assumed that the structure is as described above. To actually open a book using this, first open the page you want to open as shown in Fig. 2 and attach this tool from the left and right, with the plate on the outside of the book and the presser on the inside. When the book is placed on the table with the board facing down in this state, the weight of the book is applied to the board and the board is pushed down to try to be parallel to the table. On the other hand, since this tool is fixed from the front and back covers to the open page, the force that the plates become parallel is transmitted as the force to open the book and finally becomes as shown in Figure 3 and the book opens. It will be in a state of being lost. If the page you want to open is at the very beginning or the end of the book, one tool is enough as shown in FIG.

[0007]

[Effect of the invention]

 The present invention has an extremely simple structure, and the physical force and principle used are also extremely simple, but the effect is surprisingly effective and practical. If the above procedure is carried out, the book will be in an open state even if the hand is released by a very simple procedure, but the more detailed effects are as follows. Since the tool is fixed as a whole from the page to the cover, the force that the book leans on the two intersecting plates to make them parallel is maximized as the force to open the book. In addition, the rigid plate portion also has the effect of maximizing force transmission. Moreover, the structure of the book itself is useful for allowing two separate tools to function as one tool, eliminating the need to process and connect the two tools. In this way, by utilizing the properties of the book itself, the tool itself becomes extremely simple, and since it can be manufactured in the form of processing a single material, it is seamless, lightweight, fragile, and inexpensive. Therefore, it is extremely superior in terms of portability and practical utility. Also, when it is made of transparent plastic, the text under the holder can be seen through and can be read, so this tool does not get in the way. It can also be used as a ruler if it has a scale.

Claims (3)

[Utility model registration claims] 1. A front and back cover of a book and a page to be opened are sandwiched by one end of a hard, thin and long plate of plastic, metal or the like, the length of which is sufficiently longer than the width of the book. Characterized by a hairpin-shaped holder, by using two of them, the book opening tool is used to keep the book open by using the weight of the book as the force to open the page. 2. An open-ended device which prevents the characters of a book from being obscured by this tool by manufacturing the device according to claim 1 with a transparent plastic. 3. An opening / closing tool having a ruler function by adding a scale to the plate portion of claim 1.
