Description

[Detailed explanation of the idea] The present invention relates to a file for binding documents.

There are various types of documents that can be bound in files, but for example, in the case of text materials, thick documents of several dozen pages or more are coated with adhesive such as hot melt on at least one side to prevent the pages from opening. There is a mode in which the page is hardened and then cut open with a paper knife to open the page as the study or test progresses.

The purpose of the present invention is to provide a system suitable for such usage,
Another object of the present invention is to provide a file with a simple structure that is suitable for conventional and ordinary usage.

Fig. 1 shows an external perspective view of the embodiment of the present invention with the file main body opened and the movable member closed;
The figure shows a perspective view of the exterior with the movable member opened.
FIG. 3 shows a longitudinal cross-sectional view of the main parts.

The file body consists of a plate-shaped body such as cardboard or a plastic sheet, and includes a top plate 1, a back plate 2, and a back plate 3.
are connected to each other by bending parts 4 and 5 so as to be freely openable and closable. Therefore, when the cover 1 is opened, the cover 1, the back plate 2, and the back plate 3 are lined up on one plane and spread out on the desk.

The binding tool 6 is provided on the side of the back plate 2 close to the back plate 3. That is, the base 7 of the binding tool is a rectangle whose long sides are sides 8 and 9 parallel to the bent portion 5 of the file body, and is fixed to the inner surface of the back plate 2 by appropriate means. Two straight binding rods 10, 10 are installed at a predetermined interval along the side 9 farther from the bent portion 5. Along the side 8 closer to the bent part 5,
In addition, two straight cylindrical supports 1 are provided at positions corresponding to the binding rods 10, 10 at the same interval as the binding rods.
1 and 11 are planted. However, this support 1
1 has a square end portion 11a, and an inwardly bent portion 11b for pressing the upper end of the spring 13 is formed approximately in the middle. Movable member 1
2 includes a linear insertion portion 12a which is normally inserted and held within the cylindrical support 11, a transition portion 12b which is continuously formed from the upper end of the insertion portion and curves to extend to the tip of the binding rod 10, and The insertion portion 1 is composed of a spring support portion 12c that extends downward through the bent portion 11b to support the spring 13.
Only the upper end portion 12d of 2a is formed to have a square cross section. A helical compression spring 13 is inserted into the spring support portion 12c, and a presser body 1 is attached to the lower end.
4 is fixed.

Next, we will explain how to use it and how it works.

Normally (first state), as shown in FIGS. 1 and 3, the restoring force of the spring 13 presses the movable member 12 toward the base 7, and the transition portion 12b
The ends of the binding rods 10 are closely connected and continuous. In this state, the square hole 11b at the upper end of the support and the square cross section 12d of the movable member 12
Since the movable member 12 is fitted, the movable member 12 cannot rotate.

When the movable member 12 is slightly lifted by hand, it becomes freely rotatable, and when the hand is released after it has been rotated by 90° or 180°, the square cross-sectional portion 12d returns to the square hole 1.
1b, this rotational state (second state) is stably maintained.

By keeping the movable member 12 in the second state, even if the document to be filed is in the form of a block, it can be easily stapled onto the binding pin 10. After the document is closed, if the movable member 12 is returned to the first state, then when the document is opened, it can be smoothly transferred to the support body 12 via the transition portion 12b, and the opened document is transferred to the file. Since it rests stably on the cover 1 and back plate 3 of the main body, it does not interfere with writing on the document remaining on the binding pin 10.

The rotation prevention means of the present invention is not limited to the above-described square hole and square cross-section shaft, but, for example, a pin may be protruded from the side surface of the movable member 12 and placed at a predetermined position on the upper edge of the support body 11. This can be accomplished by other known means, such as forming a cut groove into which a pin is inserted. Further, the square hole and the square cross-section shaft are made circularly rotatable, and instead, opposite corners 15 and 16 of protrusions and recesses are provided at the tip of the transition portion 12b of the movable member and the tip of the binding rod 10, This may prevent rotation.

According to the present invention, in the second state, the area above the binding bar is completely open without any obstruction, so even block-shaped documents can be easily stapled without any restrictions on their thickness. . Also, since the binding tool is attached to the side of the back plate, you can open the page and do office work while the document is still filed, making it ideal as a text file.

Claims (1)

[Scope of utility model registration request] A file main body in which a top plate, a back plate, and a back plate are connected by bending portions, a base of a binding tool fixed to a side of the inner surface of the back plate close to the back plate, and the folded part of the base. A plurality of binding rods are planted straight along one side parallel to the curved portion, and a plurality of binding rods are planted at positions corresponding to the planting positions of the binding rods on the other side parallel to the bent portion of the base. A movable member that is integrally formed with a linear insertion portion that fits into the support and a curved transition portion extending over the tip of the binding pin, and the insertion portion of the movable member is attached to the base. a spring provided inside the support for pressing toward the
