Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is a book curl prevention device in which the main body E is inserted in the binding portion to prevent the curl of the page of the book, and the acrylic plate D prevents the curl due to the force of the spring B.

[0002]

[Prior art]

 A conventional tool for suppressing the warpage of a page is to press the left and right ends of the book with wire-like objects to fix it with weights, to fix it on a flat surface with a suction cup, or to clip the entire book with clips.

[Problems to be solved by the invention]

 The page stop of a conventional book is large and heavy because the left and right ends of the book are fixed by wire-like objects with wire-like ones. The suction cup type has a limited range of use. With the clip type, since the entire book is sandwiched, a spring mark is attached to the book and the book is damaged.

Therefore, in the present invention, a thin metal plate like a blade is inserted in the binding portion, and the transparent acrylic pressing plate gently presses the page with the force of the spring, so the book is messy and the pressing plate is removed and It can be stored and can be carried for school, library, and travel.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the book page curl preventive tool of the present invention is made of a thin metal material so that the main body E can be inserted into the binding portion of the book.

Further, the transparent acrylic pressing plate D was fastened and fixed to the support metal H screwed to the shaft by the C of the main body with the urea screw through the storage window K.

Further, the storage window provided on the transparent acrylic pressing plate is made large enough to accommodate a urea screw.

[0008]

[Embodiment of the invention]

 When using the book page curl prevention device configured as described above, when stopping the page of the book, hold the curl of the book by hand to stop it, but when it further curls, You can use it by inserting it lightly. When carrying it, loosen the urea screw G and pull out the acrylic plate. To store this acrylic plate, you can store it in the main body by loosening the urea plate storage window after the urea screw, loosening the urea screw, and then firmly tightening the end of the urea screw by inserting it into the bottom of the storage window. .

【Example】

 An embodiment will be described with reference to FIGS. 1 to 2. When the portion C of the curl prevention device main body A is inserted into the binding portion of the book to prevent the curl of the page of the book, the part E to be inserted is At the bottom of the main body A, a support metal fitting H is provided around the middle portion C as an axis, and an acrylic plate is attached thereto with a urea screw. This acrylic plate can be moved up and down to accommodate pages of any thickness by the force of B's spring.

In the embodiment shown in FIG. 3, a hole C is formed in an acrylic plate supporting metal fitting attached to the shaft at the center C of the main body, and a nut I is provided in the lower portion thereof, and a urea screw is fixed to the metal fitting.

In the embodiment shown in FIG. 4, in order to fix the transparent acrylic pressing plate D to the acrylic plate supporting member H with the urea screw G, a storage window K is provided at one end thereof.

In the embodiment shown in FIG. 4, the storage window K is provided at one end of the transparent acrylic plate, but its shape is such that it has a horizontal bottom and a large amount of urea screw passage.

In the embodiment shown in FIG. 5, the transparent acrylic pressing plate D is separated from the acrylic plate support metal fitting H by loosening the screw from the front of the urea screw G, and the acrylic plate D is stored behind the urea screw G. The window K was inserted, and the bottom portion of the window was fastened with the urea screw G to fix it to the main body A.

In the embodiment shown in FIG. 6, the transparent acrylic pressing plate D of FIG. 5 is fixed to the main body A, and the urea screw G tightens the bottom portion of the storage window K of the transparent acrylic pressing plate D. The effect of the urea screw G is made clearer from the side of the shape fixed to the main body A.

[0015]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

The pages of the book were safe and easy when I tried to stop the curling using a curl prevention device.

When the main body E is inserted into the binding portion of the book, it is a thin metal plate like a blade, so that it is effective in terms of operation.

Further, since the transparent acrylic pressing plate is transparent when a page is pressed, printed characters and pictures of a book can be clearly seen.

[0019] The transparent acrylic pressing plate can be stored in this holiday, convenient to carry, has a wide range of use, and has the effect of being usable at school, library, and travel.
