Book clip

Abstract

This book clip reliably prevents pages from flipping back and closing in thick textbooks and other books, without leaving any marks on the book, and with a lightweight and compact design. [Solution] The book clip has weights 3 attached to the two handle parts 2 of the clip that holds the book. The lever principle is used to prevent pages from rolling back. A cushioning material 4 such as felt is attached to the inside of the opening of the clip body 1 to prevent marks from being left on the book. The opening opens to about 2 cm, the overall size fits in a pencil case, and the weight is about 52 g.

Description

Technical Field

[0001] The present invention relates to a book clip with an appropriate weight added to the handle to hold a book in an open state.

Background Art

[0002] When using books such as textbooks and reference books, newly purchased books have strong paper binding, and it is necessary to hold the pages with a clip or the like so that the book does not close. It is required as a necessary characteristic of a book clip to be small, easy to carry, capable of holding the pages of a book with a simple operation, excellent in durability and reusable multiple times, and sold at as low a price as possible.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Commercially available book clip products currently available include those with a large shape and heavy weight, those with a narrow opening of the clip and a small number of pages that can be sandwiched at one time, those with a strong force at the location where the pages are sandwiched and leaving marks on the pages, those with poor durability due to plastic materials, and those with high prices. The present invention aims to solve all of these problems.

Means for Solving the Problems

[0004] The problems of conventional book clip products are divided into the following five points for discussion, and the advantages of the present invention are explained for each problem point. (1): The point that the shape is large and the weight is heavy, (2): The point that the opening is narrow and the number of pages that can be sandwiched at one time is small, (3): The point that the force at the location where the pages are sandwiched is strong and leaves marks on the pages, (4): The point that the durability is poor due to plastic materials, (5): The point that the price is high

[0005] ▲1▼: Regarding the large size and increased weight, most book clips currently on the market are designed to prevent pages from returning to their original state by using the weight of the book clip itself as a counterweight. In contrast, this invention uses the part that holds the pages as a fulcrum and utilizes the principle of leverage to add weight as far away from the end of the pages as possible. This prevents an increase in the overall weight of the product while effectively holding the pages in place.

[0006] ▲2▼: Regarding the issue of the narrow opening limiting the number of pages that can be clipped at once, this invention utilizes the structure of a double clip to create an opening that opens approximately 2 cm, making it possible to clip more pages at once. It can securely clip even thick textbooks.

[0007] ▲3▼: Regarding the issue of the strong force applied to the page-clamping area leaving marks on the page, this invention features a structure in which cushioning material such as felt is attached to the inside of the clip's opening (the part that directly clamps the book). This achieves a structure that maintains strong holding power while minimizing marks and scratches on the page.

[0008] ▲4▼: Regarding the lack of durability due to the plastic material, the main body and handle are made of highly durable materials such as metal, resulting in a robust construction that can withstand long-term use.

[0009] ▲5▼: Regarding the high price, it has a simple structure based on existing clip structures with added weights and felt, which allows for reduced manufacturing costs and makes it possible to offer it at an affordable price. In addition, the overall weight is kept down to approximately 52g, and it has been made small enough to fit in a pencil case, making it highly portable. [Effects of the Invention]

[0010] This book clip allows you to securely hold open even thick textbooks or other books with pages that tend to spring back, thanks to the lever principle provided by the weight on the handle. It is also lightweight (approximately 52g) and compact, making it easy to store in a pencil case or similar, and convenient to carry. Furthermore, its wide 2cm opening allows it to hold many pages, and the felt lining on the inside of the opening prevents marks from being left on the book, making it extremely practical for studying or working. [Brief explanation of the drawing] [Figure 1] This is a perspective view showing the overall structure of the book clip according to the present invention. [Figure 2] This is a diagram showing a side view of the book clip according to the present invention. [Modes for carrying out the invention]

[0011] The embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a perspective view of the book clip of the present invention. The book clip of the present invention consists of a clip body (1) for holding the pages of a book and two handle parts (2) for opening and closing the body (1).

[0012] Each of the two handle sections (2) is equipped with a rectangular block that acts as a weight (3) at its tip (away from the main body (1)). The weight of these weights (3) and the lever principle effectively suppress the force that causes the pages of a book to return to their original position.

[0013] Felt (4) is attached to the inside of the opening of the main body (1) that directly holds the pages. This reduces damage to the paper caused by the clamping force and prevents clip marks from being left.

[0014] The opening of the clip body (1) can open up to approximately 2 cm, accommodating even thick books. The overall weight is adjusted to approximately 52g, making it a convenient size for carrying in a pencil case. [Explanation of Symbols] 1. Clip body 2. Handle part 3 weights 4.
