Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a paper clip used for binding papers such as catalogs, pamphlets, copy paper, albums, and clear files.
More specifically, the paper clip relates to a paper clip that can be easily inserted and removed from one sheet to multiple sheets without making holes, and has perfect holding power even when thin sheets are bound.

[Conventional technology]

Conventionally, as a means of filing papers without making holes, as shown in Japanese Patent Publication No. 60-33680,
2. Description of the Related Art Paper clips are known that are made of a cylinder with a substantially rectangular cross section and a single slit.

[The problem that the invention attempts to solve]

Generally, papers such as catalogs, pamphlets, albums, etc. are initially produced in small numbers (for example, 1 sheet).
In many cases, you start with one and gradually increase the number until you complete the whole thing.

However, the paper clip of the above-mentioned Japanese Patent Publication No. 60-33680 clamps and holds the vicinity of one side end of the paper between a plate with a pin and a hole plate, and slides this into the storage opening of a cylindrical body with a substantially square cross section. When adding or replacing papers, the combination of the pin-equipped plate and the hole plate must be released each time, and then recombined after the addition or replacement is completed, which is a hassle. .

The technical problems to be solved by this invention are that it is possible to hold papers without using a plate with pins or a hole plate, it is easy to add or replace papers, and it has the ability to hold papers after binding. This means that everything will be safe.

[Technical measures taken to solve the technical problems of the invention]

The technical means taken to solve the technical problem is to make one wall of a cylindrical body with a substantially square cross section cave inward to form a depressed wall, and to form a slit in the longitudinal direction of the center of the depressed wall. On the inside of the paper clip body,
The paper clip has a built-in inner clip having a shape similar to that of the paper clip body, the inner clip is made of a flexible material, and the slit width of the inner clip is smaller than the slit width of the paper clip body.

[Effect]

This invention has an inner clip made of a flexible material with a substantially similar shape built into the inside of the paper clip body, so it can hold thin sheets of paper that are difficult to securely hold using only the slit section of the paper clip body. Even similar items can be held securely with the small slit portion of the flexible inner clip. In addition, in the case of thick paper, even if the slit part of the inner clip tries to expand more than necessary, the paper clip body on the outside, which has good shape retention, will hold the inner clip from the outside. The slit portion of the inner clip does not expand excessively, which ensures perfect shape retention.

〔Example〕

To explain the present invention with reference to the embodiments of the drawings, Fig. 1 is a perspective view of the invention, Fig. 2 is a central vertical sectional view of the previous figure, Fig. 3 is a perspective view of the invention in a state where papers are being held, FIG. 4 is a perspective view of the invention provided with a thick cover.

In the present invention, a paper clip body 1 is formed of a shape-retaining material such as vinyl chloride, and an inner clip 2 is built inside the paper clip body 1. The inner clip 2 is made of a flexible material such as polypropylene, synthetic paper, or rubber, and the width of the slit 2a is smaller than the width of the slit 1a of the paper clip body 1. There is.

Therefore, for example, when the side edge of a sheet of thin paper 3 is press-fitted into the slits 2a and 1a, the open end of the slit 1a will firmly hold the paper under pressure. In particular, if the open end of the slit 1a is made of a material with a large coefficient of friction, this holding force will be improved. Further, when the paper 3 that has been held once is to be removed for reasons such as replacement, it is possible to pull out the paper against the clamping force of the slit 1a by pulling it out with a certain amount of force.

In addition, when holding thick papers, it is convenient to slide the paper through the edges of the slits 2a and 1a, rather than from the front, if the entire paper is stapled. In this case as well, the slit 1a will hold the papers 3 under pressure, but if the slit 1a is likely to expand excessively, the paper clip main body 1, which maintains a predetermined strength, will be held from the outside. This will support the overall shape.

Further, as shown in FIG. 4, if a thick cover 4 is integrally attached to a paper clip, it becomes a book shape suitable for filing.

[Effect of idea]

Therefore, with this invention, it is possible to easily insert and remove paper from thin to thick.
Once locked, the slit opening end of the inner clip securely holds the paper under pressure, allowing it to be firmly held, and if necessary, it can be removed by applying strong force. It has excellent effects.
