Description

Technical Field

[0001] The invention relates to a book page turning and pressing clamp, belonging to the technical field of school supplies. Background Art

[0002] When reading, we need to use both hands to hold the pages that have been read on one side and the pages that are yet to be read on the other side. If we do not separate the two parts with our hands, the page that has just been turned over will automatically turn to the other side, causing the book to close automatically. This is especially true for thicker books. If you cannot guarantee that you can use both hands to hold the book and can only use one hand, you can use your forearm to press down both sides of the book. This method is not only more tiring for the reader, but also if the area of ​​the book pressed by the arm is large, it will block the content of the book. If you only press down the edge of the book, although it will not block the content of the book, the pages will break away from the force of the arm if you are not careful, and the book will close automatically, seriously affecting the reader's reading interest.

[0003] In order to solve the problem of paging in books, the existing page turning device for reading includes a carrying plate with page pressing plates on both sides of the carrying plate. In order to ensure that the pages of the book can enter the page pressing plates, there needs to be a space between the page pressing plates and the carrying plate to accommodate the pages. When in use, the book is placed on the carrying plate, and the page pressing plates on both sides act on the pages of the book on both sides respectively. Although the page pressing plates have a certain limiting effect on the pages, for thicker new books, the page pressing effect of the page pressing plates is not good, and the pages are easily turned to the other side automatically. In addition, this reading paging device requires a carrying plate, which makes the page turning device bulky, expensive, and inconvenient to carry. There is also a page turning device in which the pressing plates are placed on the carrying plate. A pressure plate is used to separate the pages of a book at the center seam. To ensure the stability of the pressure plate, the pressure plate needs to be hinged to a supporting plate. This type of page turning device, with the pressure plate placed at the center seam, functions somewhat like a bookmark. Although it can separate the pages of a book that have been read from those that have not, the pressure plate needs to be repositioned at the center seam of the book each time a page is read. This type of page turning device requires manual placement at the spine of the book each time a page is turned, which seriously affects reading efficiency and quality. In addition, in order not to affect the content of the book, the small size of the pressure plate cannot prevent the pages from automatically closing, and cannot fundamentally solve the problem of paging when reading. Although existing devices that can automatically turn pages have a high degree of automation, they are expensive and bulky, and are not widely used. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a book page turning and pressing clamp which has a simple structure, good page pressing effect, small size, convenient carrying and low cost.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A book page turning and pressing clamp comprises a book clamp and a page pressing rod, the book clamp comprises a pair of clamping plates, the clamping plates are provided with hinged ear plates, the ear plates are provided with pin holes, the page pressing rod comprises a clamping section and left and right pressing claw sections, the clamping section is inserted into the pin hole, a spring or elastic sheet is provided between the pair of clamping plates, the left and right pressing claw sections and the clamping section are in a U-shaped structure, and the free end of the pressing claw section is bent downward.

[0006] The beneficial effects of the present invention are as follows: the splint is clamped on the upper part of the left side of the book, the left pressing claw section of the page pressing rod extends to the left page of the book, and the right pressing claw section extends to the right page of the book. When reading, the page that has been read manually on the right side of the book will escape from the right pressing claw section and enter the left pressing claw section. The clamping section of the page pressing rod is not easy to rotate by the torsion spring and the ear plate locking of the splint, ensuring that the left and right pressing claw sections are kept above the left and right book surfaces of the book to limit the left and right pages of the book. Once the page turning pressing clamp is clamped on the book, the entire page pressing process only requires turning the pages without moving the page turning pressing clamp, so as to achieve the purpose of paging. With the page turning pressing clamp, the book is no longer just laid flat on the table, and the book can also stand on the table. Under the action of the page turning pressing clamp, the standing book can stably press the pages on both sides of the book to prevent the book from closing. In summary, the present invention has a simple and compact structure, is easy and quick to operate, is small in size, easy to carry, has a good page-turning effect, can prevent the pages on both sides of the book from closing, and improves reading efficiency and quality. The present invention has a simple and compact structure, low production cost, and has great promotion value and environmental value.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the cross section of the clamping section is flat.

[0009] The beneficial effect of adopting the above further scheme is that the clamping section passes through the ear plates on both sides, and the spring is sleeved on the outside of the clamping section between the ear plates. A pair of clamping plates can clamp the book under the action of the clamping section and the spring, and the pressing claw section of the page pressing rod limits the page and plays a role in pressing the page. When the page pressing rod presses the page, the page will also have a reaction force on the pressing claw section of the page pressing rod, and as the thickness of the page increases, the reaction force of the page on the page pressing rod will continue to increase, and the force on the pressing claw section will increase. If the clamping section The cross-section of the clamping section is circular. This reaction force will cause the clamping section to rotate around the pin hole of the ear plate as the central axis, and the pressure claw section will rotate and lift accordingly, unable to press the pages, causing the book to automatically close. However, with a flat clamping section, the intersection of the pin holes of the two ear plates on the same side of the clamping section is a flat elliptical structure. In this way, the reaction force exerted by the page on the pressure claw section cannot cause the flat clamping section inserted in the ear plate pin hole to rotate. Therefore, the page pressing rod as a whole does not rotate, and the pressure claw section will not be separated from the page. The flat clamping section makes this mechanism suitable for pressing pages of books of different thicknesses, and is particularly suitable for pressing pages of relatively thick books.

[0010] Furthermore, the middle of the flat shape is hollow.

[0011] The beneficial effect of adopting the above further solution is that it not only meets the support strength requirement, but also reduces the weight of the clamping section, making it easier to carry.

[0012] Furthermore, the cross section of the clamping section is rectangular or elliptical.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the rectangle or ellipse is easy to process, and the pin hole of the inserted clamping section expands outward under the action of the spring, so that the intersection of the two pin holes naturally forms an elliptical hole structure that matches the rectangle or ellipse. The clamping section is stable in the elliptical hole structure. Facing the reaction force of the book page, the clamping section of the page pressing rod does not rotate. If the page pressing rod does not rotate, the pressure claw section will not separate from the book page, and the purpose of the page pressing rod to stabilize the page can be achieved.

[0014] Furthermore, the left and right pressing claw sections are both inclined to the right or to the left.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that if the mechanism clamps the left part of the book, the pressure claw section tilts to the right to ensure that the left and right pressure claw sections can press the center parts of the left and right sides of the book respectively, so that the pages under the left and right pressure claw sections are more stable; if the mechanism clamps the right part of the book, the pressure claw section tilts to the left to ensure that the left and right pressure claw sections can press the center parts of the left and right sides of the book respectively, so that the pages under the left and right pressure claw sections are stable, avoiding the situation of unstable page pressing.

[0016] Furthermore, the left and right pressing claw sections each include an upwardly bent ascending section and a downwardly bent pressing section.

[0017] The beneficial effect of adopting the above further solution is that the design of the rising section enables the pressing claw section to restrict more pages, making it easier to apply the mechanism to thick books with many pages.

[0018] Furthermore, the free end of the pressing section of the pressing claw section is a planar structure or a smooth arc surface structure.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that the free end of the pressure claw section can be a plane, which stabilizes the page pressing and facilitates the entry of the book page into the pressure claw section, or it can be an arc surface, with the outer end of the arc surface curled up to avoid damage to the page during the turning process. Specifically, when manually turning the lower part of the read page, the upper part of the page can smoothly pass through the pressure claw section on one side, and then smoothly enter the pressure claw section on the other side, and can achieve a stable page pressing effect on the book.

[0030] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] like Figure 1-Figure 7 As shown, a book page-turning clamp includes a book clamp and a page-pressing lever. The book clamp includes a pair of clamping plates 1, each provided with a hinged ear plate 11, each provided with a pin hole 12. The page-pressing lever 2 includes a clamping section 21 and a left pressure claw section 22 and a right pressure claw section 23. The clamping sections are inserted into the pin holes. Taking a spring as an example, a spring 13 is provided between the pair of clamping plates and is sleeved on the clamping section. The left and right pressure claw sections and the clamping section form a U-shaped structure as a whole, and the free ends of the pressure claw sections are bent downward. The spring is a torsion spring.

[0032] The cross section of the clamping section is flat. The clamping section passes through the ear plates on both sides, and the spring is sleeved on the outer side of the clamping section between the ear plates. A pair of clamping plates can clamp the book under the action of the clamping section and the spring, and the pressure claw section of the page pressing rod limits the page of the book and plays a page pressing role. When the page pressing rod presses the page, the page will also have a reaction force on the pressure claw section of the page pressing rod. Moreover, as the thickness of the page increases, the reaction force of the page on the page pressing rod will continue to increase, and the force on the pressure claw section will increase. If the cross-section of the clamping section is circular, the reaction force will cause the clamping section to rotate with the pin hole of the ear plate as the central axis, and the pressure claw section will rotate and lift accordingly and cannot press the page, causing the book to close automatically; and if a flat clamping section is adopted, the intersection of the pin holes of the two ear plates on the same side of the inserted clamping section is a flat elliptical structure. In this way, the reaction force exerted by the book page on the pressure claw section cannot make the flat clamping section inserted in the pin hole of the ear plate rotate, so the page pressing rod does not rotate as a whole, so the pressure claw section will not be separated from the page. The flat clamping section enables the mechanism to be suitable for book sheets with different thicknesses, and is particularly suitable for thicker book sheets.

[0033] The cross-section of the clamping section is rectangular or elliptical. Rectangular or elliptical shapes are easy to process. The pin hole of the clamping section is expanded outward under the action of the spring, so that the intersection of the two pin holes naturally forms an elliptical hole structure that matches the rectangular or elliptical shape. The clamping section is stably located within the elliptical hole structure. In the face of the reaction force of the page, the clamping section of the page pressing lever does not rotate. If the page pressing lever does not rotate, the pressure claw section will not separate from the page, thereby achieving the purpose of the page pressing lever stably pressing the page.

[0034] like Figure 4 As shown in the figure, this figure shows the position of the pin holes of the two ear plates when the clamping section is rectangular; Figure 5 As shown in the figure, this figure shows the position status of the pin holes of the two ear plates when the clamping section is elliptical.

[0035] like Figure 8 and Figure 9As shown, the flat shape is hollowed out in the middle. The clamping section is made of two parallel steel wires. Specifically, the two ends of the steel wires are welded and fixed, with a gap between the two wires. This not only meets the support strength requirements, but also reduces the weight of the clamping section, making it easier to carry.

[0036] The pin holes of the two ear plates expand outward under the force of the torsion spring of the book clamp, and the intersection of the two pin holes naturally forms an elliptical hole structure that matches the cross-section of the clamping section. When the handle end of the book clamp is manually gripped, the clamping end of the book clamp opens, the spring of the book clamp twists naturally, the clamping section rotates as the splint opens, the pressing claw section of the page pressing rod is lifted, and the book clamp is smoothly clamped to the book. When the book clamp clamps the book and the hand is released from the book clamp, the clamping end of the book clamp is clamped, the spring of the book clamp twists and resets naturally, the clamping section rotates and resets as the splint closes, and the pressing claw section of the page pressing rod is naturally pressed on the book page. In addition, the pressing claw section itself has a certain elasticity, so the book page turning clamp can be suitable for turning pages of books of different thicknesses.

[0037] The left and right pressure claw sections are all tilted to the right or left. Figure 6 As shown, if the mechanism clamps the left side of the book, the pressure claw section tilts to the right to ensure that the left and right pressure claw sections can press the center of the left and right sides of the book respectively, making the book pages under the left and right pressure claw sections more stable; Figure 7 As shown, if the mechanism clamps the right part of the book, the pressure claw section tilts to the left to ensure that the left and right pressure claw sections can press the center parts of the left and right sides of the book respectively, so that the pages under the left and right pressure claw sections are stable, avoiding unstable page pressing.

[0038] The left and right pressing claw sections all include an upwardly bent rising section 24 and a downwardly bent pressing section 25. The design of the rising section enables the pressing claw section to limit more pages, making it easy to apply the mechanism to thick books with many pages.

[0039] The free end of the lower pressing section of the pressure claw section is a flat structure or a smooth curved surface structure 26. The free end of the pressure claw section can be flat, which stabilizes the page pressing and facilitates the page to enter the pressure claw section, or it can be curved, with the outer end of the curved surface tilted upward to prevent the page from being damaged during the turning process. Specifically, when the lower part of the page is manually turned, the upper part of the page can smoothly pass through the pressure claw section on one side and then smoothly enter the pressure claw section on the other side, thereby achieving a stable page pressing effect on the book.

[0040] The page pressing rod is made of steel, aluminum or PVC. It can not only ensure the support strength of the clamping section and the stability of the page pressing, but also is easy to process and manufacture, light in weight and easy to carry.

[0041] The clamping plate is clamped on the upper part of the left side of the book, and the left pressing claw section of the page pressing rod extends to the left page of the book, and the right pressing claw section extends to the right page of the book. When reading, the page read on the right side manually escapes from the right pressing claw section and enters the left pressing claw section. The clamping section of the page pressing rod is locked by the torsion spring and the ear plate of the clamping plate and is not easy to rotate, ensuring that the left and right pressing claw sections are kept above the left and right book surfaces of the book to limit the left and right pages of the book. Once the page turning pressing clamp is clamped on the book, the entire page pressing process only requires turning the pages without moving the page turning pressing clamp, so as to achieve the purpose of turning pages. The left and right pressing claw sections of the page turning pressing clamp are used to stably press the pages on both sides of the book, which can not only act on books that are laid flat, but also books using the page turning pressing clamp can stand stably while meeting the requirements of turning pages, and the standing books will not close.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
