Description

[Technical Field]

[0001] This invention relates to a book cover that allows you to easily hold a book with one hand and keeps the page you want to read open while reading. [Background technology]

[0002] The main functions of conventional book covers are to protect the book and to prevent people around you from seeing the title of the book you are reading, and the book cover itself does not have any functions to make the book easier to hold or read. Furthermore, when reading, you often have to stand and hold the book in one hand while traveling on a train, etc. In such cases, with a conventional book cover, you have to hold the book in one hand and support the pages with your fingers to prevent them from closing. Therefore, book covers that keep the page open while making it easier to hold the book have been disclosed as prior art (References 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2014-162077 [Patent Document 2] Publicly Disclosed Utility Model Publication No. Heisei 2-126864 Summary of the Invention [Problem to be solved by the invention]

[0004] Reference 1 features strings on both ends of the front of the book cover that can be threaded through fingers, making it easier to hold the book. However, because the strings are located on both ends, it is assumed that the book will be held with both hands. If only one hand is threaded through the string and the book is held with that hand, the force of the lever principle will be very great on the fingers that are threaded through the string. The cover also has a transparent sheet on top that can be placed over open pages to keep them open, but this requires the transparent sheet to be removed each time a page is turned, which is cumbersome. Furthermore, depending on the material of the transparent sheet, the ink from the book may transfer to the sheet, or it may lose its transparency over time. Another issue is that sheets made of materials that do not have these concerns are expensive.

[0005] In Reference 2, a tape is sewn to the bottom of the front of the book cover, allowing the reader to place the four fingers (except the thumb) through the tape, making it easier to hold the book. However, because the tape is sewn to the bottom, the weight of the book is supported by the tape, requiring the reader to place the thumb inside the book for support. Furthermore, a roughly U-shaped metal or synthetic resin clamp keeps the page open while reading, and while turning the page is easy, mass-producing book covers for various book sizes requires a separate mold for each size to create the roughly U-shaped clamp. Furthermore, the structure of the roughly U-shaped clamp, which uses the restoring force of a helical spring to keep the pages open, presents challenges, including a significant impact on the unit price of the product in terms of the number of production steps and costs.

[0006] This invention was devised to solve the problems of conventional book covers, allowing the book to be held comfortably in one hand, and while reading, the pages remain open, allowing for easy page turning. Even if you stop reading and close the book, the next time you open it, the book will automatically open to the page you were reading. Furthermore, the materials used in production do not require molds, and only materials commonly used in general sewing products are used. The number of production steps is almost the same as for general book covers, making it easy to use in mass-produced products, even in terms of cost. [Means for solving the problem]

[0007] The back of the book cover of the present invention has tapes such as rubber belts arranged on both the left and right sides, connecting the top and bottom edges of the book cover body, and sewn to the top and bottom edges of the book cover body. The sleeves of the book cover of the present invention are also characterized by being roughly U-shaped and extending from both ends of the top and bottom edges of the book cover body, and when folded inward, they are connected to the top and bottom edges of the opposing book cover body with elastic members such as rubber tape. The front of the book cover of the present invention also has tapes sewn in that can be threaded through. The tape is sewn in the appropriate position so that the fingers touch the book when the book is opened and placed at an angle in the palm of the hand, ensuring stability without losing balance. [Effects of the Invention]

[0008] The present invention achieves the following advantages. After threading the front and back covers of a book through the tapes connecting the top and bottom edges of the back of the book cover, first insert all pages except the first page into the back cover sleeve, and then insert only the first page into the front cover sleeve. When a book with the book cover of the present invention is opened, the four sleeves (top, bottom, left, and right) hold the page in place, keeping the page open. Furthermore, because the sleeves only partially cover the top, bottom, left, and right, they do not cover the printed portion of the open page, preventing impediments to reading. Furthermore, by pinching the top edge of the back cover page that is not held down by the sleeve with the fingers of the side not holding the book, the page that was previously held down by the sleeve can be easily removed, and the page can be easily inserted into the front cover sleeve, ensuring smooth page turning, which is essential when reading. Furthermore, the front side of the book cover of the present invention has tape sewn into the area where the fingers would be when the book is placed open and tilted in the palm of your hand to stabilize it without losing balance. Therefore, when you hold the book with your fingers inserted through the tape, the center of gravity of the book is stably placed on the fingers inserted through the tape, making it easy to hold the book with one hand. Furthermore, if you stop reading and close the book, the four sleeves on the top, bottom, left, and right sides of the page you were reading will act as a bookmark, allowing you to resume reading. When you open the book, the page you were reading will naturally open. Furthermore, no materials, such as metal or synthetic resin, that require molds are required for production, and production can be done using only materials commonly used in sewing products. Furthermore, the number of production steps is almost the same as for a regular book cover, so production costs are not increased by the present invention. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] The book cover of the present invention will be described in detail below with reference to the embodiment shown in the drawings. Figure 1 is a front view of the pattern for the book cover of the present invention. The sleeves (2a, 2b, 2c, 2d) are roughly U-shaped and extend from both the top and bottom edges of the main body (1).

[0011] Figure 2 is a perspective view showing the structure of the book cover of the present invention from the back. Elastic tapes (3a, 3b) are placed on both sides of the main body (1) connecting the top and bottom edges and sewn to the top and bottom edges of the main body (1), allowing the front and back covers of the book to be passed through the tapes (3a, 3b). The sleeves (2a, 2b, 2c, 2d) are connected to the opposing top and bottom edges of the main body (1) by elastic tapes (4a, 4b, 4c, 4d) when folded inward.

[0012] Figure 3 is a perspective view of the back of a book with the book cover of the present invention attached to it. After threading the front and back covers of book (5) through the tapes (3a and 3b) shown in Figure 2, all pages except page 1 are inserted into sleeves (2b and 2c), and only page 1 is inserted into sleeve (2a and 2d), completing the attachment to book (5). The sleeves (2b and 2c) and sleeves (2a and 2d) of the book cover of the present invention are roughly U-shaped, and when attached to book (5), they cover the top, bottom, left, and right edges of book (5) but do not cover the printed part, so reading is not hindered. Furthermore, because sleeves (2a, 2b, 2c, and 2d) hold down the top, bottom, left, and right edges of book (5), the page being read can be kept open. Also, when you have finished reading the open page, you can easily pull out the page from the sleeve (2b / 2c) by pinching the top edge of the page of the book (5) that is not being held down by the sleeve (2b) with the fingers of the hand not holding the book, and then easily insert the page into the opposite sleeve (2a / 2d), making it easy to turn the page.The elastic tape (4a / 4b / 4c / 4d) is stretchy, so it can accommodate books of various thicknesses with different page counts, and its stretchability allows it to fit even if the number of pages on the front and back covers changes and the thickness changes as you read the book.

[0013] The book cover of the present invention has a tape sewn onto the front side for passing fingers through to make it easier to hold the book in one hand. Figure 4 is a perspective view of a book opened and placed at an angle in the palm of the hand to verify the proper position of the tape for passing fingers on the front side of the book cover of the present invention. For example, placing the top, bottom, left, or right edge of the book on the palm will cause it to lose balance. In this case, if tape is sewn onto the front side of the book cover of the present invention based on the position where the thumb touches the book, strain will be placed on the fingers that have been passed through the tape to support the weight of the unbalanced book, making it difficult to hold the book stably. On the other hand, Figure 5 is a perspective view showing the front side of the book cover of the present invention with tape sewn onto the front side based on the position where the thumb touches the book when the book is opened at an angle and placed in the palm of the hand, as in Figure 4, for stable balance. In this case, when the thumb is passed through the tape (6), the book is well-balanced on the palm, so no unnecessary strain is placed on the thumb, allowing the book (5) to be held stably. In addition, when the thumb is passed through the tape (6), another tape may be sewn onto the area where the other fingers touch, and by inserting the other fingers into this tape, it becomes possible to hold the book (5) more stably. The tape (6) may also be made of a stretchy material such as rubber tape.

[0014] Figure 6 is a perspective view from the back of a book with a conventional book cover attached, held in one hand. Figure 7 is a perspective view from the front of a book with a conventional book cover attached, held in one hand. When holding a book with a conventional book cover attached in one hand, in order to keep the pages open as shown in Figure 6, it is necessary to hold the book with the index finger, middle finger, and ring finger from the front as shown in Figure 7, while pressing the open pages with the thumb and little finger on the back.

[0015] Compared to reading a book with a conventional book cover, this invention allows you to easily turn pages while keeping the pages open, and allows you to read while holding the book comfortably in one hand.It also realizes a structure that allows the book to automatically open to the page you were reading when you open it, even if you stop reading and close it.
