Field of the Invention The present invention relates to a file for storing documents equipped with a mechanism for binding documents, and in particular, a sheet of PP (polypropylene) resin constituting the file body is cut out and partially cut up. The present invention relates to a file having a structure in which a binding tool including a rotating elongated fastener portion and a notch engaging portion is formed, the elongated fastener portion is twist-fitted, and locked in a restored state.

[0002]

2. Description of the Related Art As files for binding documents used in companies, offices, etc., there are many products in various formats on the market. Expensive files are equipped with a complicated document binding tool. On the other hand, however, there is a need for inexpensive, durable, and long-lasting files. A file with a simple structure in which a metal binding device is equipped on the cover of paper is generally used, but products that use a synthetic resin sheet such as vinyl chloride for the cover have also been developed due to the problem of durability. However, in the case of products made of synthetic resin sheets or cardboard, it is necessary to attach a document binding tool to the file body,
In addition, the document binding device itself as a component needs to be manufactured separately.

Polypropylene has a characteristic that it does not break even if it is bent many times, and it has a high resilience even if it is bent or twisted due to its elasticity, and it can easily return to its original state. Moreover, there is a feature that it can be easily processed. Therefore, a polypropylene resin sheet is used as a material of a file which has excellent durability and can be manufactured at low cost, but it is necessary to equip a document binding mechanism, so that the cost is inevitably high. In addition, a product in which one PP (polypropylene) resin is punched out in one process has been developed for the purpose of supplying an inexpensive product by omitting the work process. There was a problem, and the durability of the fastener part was not sufficient.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the drawbacks of the prior art, simplify the work process by omitting it, while also improving the durability and the efficiency of the binding work and the engaging binding. It is to provide a twisted file whose status is reliable.

In order to achieve the above object, a twist file according to the present invention is a file for forming a document binding portion on a sheet such as polypropylene which is a flexible synthetic resin, Cut out a part of the back cover side of one resin sheet that constitutes the file body and insert it into the document by forming a twist semi-rotatable elongated fastener part and cut out a part of the front cover side This is a structure in which a notch engaging portion is provided which is raised and twists the elongated fastener portion to be engaged and disengaged and engaged in a restored state.

[0006]

In the twist file according to the present invention, an elongated fastener portion is formed on a part of the back cover side which is one side of the spread page of one resin sheet, and the thin fastener part of the cover sheet side which is the other side of the spread page is formed. It has a structure in which a notch engaging part is provided by cutting out a part of it, and when using it, first of all, raise the spread pages on both sides centering on the spine cover and move the elongated fastener part and the notch engaging part toward the inside of the file. Launch. The elongated fastener portion is inserted from the tip into the fitting hole of the document to be bound, and then the tip portion of the elongated fastener portion is twisted vertically into the rectangular notch engaging portion and inserted into the vertically long width of the rectangular hole. When the hand is released from the elongated fastener part in the inserted state, the twist twisted vertically due to the restoring force returns to the original state and the head part of the tip is inserted into the hole and becomes horizontal and the elongated fastener part engages with the notch engaging part. You can stop and bind the documents. When removing the document from the twist file, twist the tip of the elongated fastener part that is locked in the notch engaging part in the vertical direction and pull out along the longitudinal direction of the rectangular notch, and then insert the document from the insertion hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A twist file according to the present invention will be described in detail below with reference to an embodiment shown in the drawings. FIG. 1 is a plan view showing the entire twist file for binding documents according to the present invention, and FIG. 2 is a perspective view showing the assembled twist file. The twist file 1 has a structure in which one PP (polypropylene) resin sheet 10 is punched and assembled, and the front and back cover parts 20 that form the file body, the elongated piece 30 that forms the document binding part, and the notch engaging part 40. It consists of and.

In the embodiment shown in the drawings, a polypropylene resin sheet is used as the flexible synthetic resin sheet 10, but an inexpensive material such as vinyl chloride or another synthetic resin sheet having excellent durability is sufficient. . Further, the elongated fastener portion, which is the cutout piece, is also flexible. The synthetic resin sheet used here is flexible and has a hardness suitable for storing documents, and also has elasticity so that it can be easily restored to its original state even when twisted by applying force. It is necessary to have resilience to do so. The twist file for binding documents according to the present invention is made of one relatively rigid synthetic resin sheet, and by partially cutting a kerf in one synthetic resin sheet and by setting a fold line,
The groove is raised and assembled, and the folds are folded to form the document binding part.

The cover section 20 is made of one synthetic resin sheet, and the cover section on one side of the spread is a front cover 21, while the other side of the spread is a back cover 22 and a spine cover section 23 at the center is provided. There is. Which side of the double-page spread is used as the front cover is free, and the width of the back cover can be set in advance depending on the thickness and type of the document to be bound.

In this embodiment, the slender fastener portion 30 is a slender cord band cut into a groove on the back cover 22.
1 and a tip head 32. Elongated string part 3 to be the body part
1 is thinly formed so that it can be twisted. The slender cord portion is a slender cord, and the base portion of the slender cord portion is formed integrally with the back cover portion 22. Further, the tip end head portion 32 is formed wider than the elongated string portion 31 so that it can be locked in the notch engaging portion. The width of the tip head portion 32 is formed to be narrower than the length of the vertical width 41a of the fitting hole 41 of the rectangular notch engaging portion 40 (see FIG. 3) described later and wider than the horizontal width 41b. The length of the slender cord portion 31 is required to be long enough to twist the distal end head portion into a twist state in which it is rotated 90 degrees in the vertical direction. Increasing the length of the slender cord can increase the number of documents to be bound. Accordingly, by twisting the entire elongated fastener portion, the tip head portion can be twisted and fitted in the cord portion in the vertical direction.

The notch engaging portion 40 comprises a rising portion 42 and a fitting hole 41. The fitting hole 41 is a rectangular hole formed in the center of the rising portion 42, and is a hole into which the tip portion 1 of the elongated fastener portion is inserted. The shape and width of the fitting hole 41 are
The space is large enough for the tip of the elongated fastener portion to be inserted, and has a width such that the tip of the inserted elongated fastener portion engages with the edge of the fitting hole and does not fall off. In the embodiment shown in the drawings, a rectangle is adopted, but the shape is not limited to this, and it may be a structure that stops at the edge of the hole and does not fall off by changing the direction of the tip of the fastener after fitting. Good. Therefore, the shape may be a rhombus, an ellipse, or a square, which have different vertical and horizontal dimensions. That is, even with a square, the distance of the diagonal line is long, so that it is inserted in a state twisted at 45 degrees, and when restored, it engages the edges of the shorter sides to lock the document. May be.

In the illustrated embodiment, a rectangular fitting hole 41 is provided.
It is shown. In the embodiment shown in FIG. 3, the shape of the fitting hole 41 that is a rectangular opening is such that the rectangular long width 41a is
The lateral width 32 of the tip head portion 32 of the elongated fastener portion to be inserted
It is configured to be larger than a. Also, the short width of the rectangle 4
1b is configured to be narrower than the width of the tip portion of the elongated fastener portion. In the embodiment, the short width 41b of the rectangle is formed to be substantially the same as the width of the elongated cord portion 31 regardless of the dimension of the tip end head portion. Since it is formed in a vertically long rectangular shape, if even the elongated fastener portion is twisted vertically and inserted at one end, the short width is extremely narrow, and there is no possibility of falling off.

The procedure of storing and removing the document is exactly the same as that of the file equipped with the conventional fastener mechanism. That is, when storing / removing documents, first, a hole is formed in the document to be bound, and the tip of the elongated fastener portion is first inserted into the hole to store the bundle of documents in the file. Next, as shown in FIG. 3A, the distal end head portion 32 of the elongated fastener portion 30 is twisted and inserted into the fitting hole 41 in a vertical state.
The tip of the elongated fastener part can be inserted in the longitudinal direction of the insertion hole by making it longitudinally (longitudinal).
When the twisting force is removed (when the hand is released), it restores to the lateral direction, and since the short width 41b of the fitting hole 41 is narrow, it remains in the engaged state and remains in the narrow width portion of the fitting hole. The distal end head portion of the elongated fastener portion is engaged and retained in a locked state.

The start-up portion 42 is a start-up portion for keeping the position where the fitting hole 41 and the elongated fastener portion 30 face each other in the front. That is, the file has a difference of 180 degrees between the bound state and the opened state, but one synthetic resin sheet is folded around the spine cover 23 to provide the front cover and the back cover with integrally engaging portions. Therefore, the engaging portion may be separated by 180 degrees. Therefore, in order to firmly maintain the engagement relationship between the fitting hole and the elongated fastener portion, the fitting hole is brought closer to the elongated fastener portion. For this reason, the startup section 42 is indispensable. In the example shown,
The fitting hole 41 provided in the front display portion has a fitting hole 41 formed in an engaging piece 43 in which a groove is further formed in the rising portion 42. That is, the fitting hole 41 may be formed by directly forming a hole in the rising portion 42. However, in the embodiment shown in the drawings, the rising portion has two stages in order to hold the engagement more reliably. The engaging piece 43 is further raised in the raising portion 42.

The rising portion 42 has a structure that reduces the burden on the elongated fastener portion that engages with the fitting hole and enhances durability and ease of use of the file. In the twist file of this embodiment, if there is no start-up part, when the cover part is opened and closed, the fitting hole and the elongated fastener part are integrally provided. Will move. The document bound by the document binder has a configuration in which the start-up unit 42 is required so that the document does not move regardless of whether the front cover of the twist file is opened or closed. Further, after the elongated fastener portion is inserted into the fitting hole and the force is released to be engaged, the force is applied to the periphery of the fitting hole due to the weight of the bound document. Therefore, as a buffer for reducing the overall movement of the bound twist file and the load on the binding tool, the engagement piece 43 that is the second-stage rising portion.
Is provided, a good locked state is maintained.

[0016]

Since the twist file according to the present invention has the structure described in detail above, it has the following effects. Since it has a simple structure, A4 size, B5 size, A5 size,
In addition to B6 size, it can be used for binding small documents. Since a single synthetic resin sheet is manufactured by punching, it is not necessary to use other members, so that it can be manufactured at an extremely low cost. The structure and principle are extremely simple, so it is hard to break,
Easy to put on and take off. Because the document binding tool is integrated with the file body,
Since it is inexpensive, durable and light, it has the advantage that it can be widely used for storing, preserving and storing documents. Because it uses polypropylene, it is guaranteed to have sufficient durability so that it will not break even if it is bent several times. Since it is elastic and has a strong restoring force, it is possible to maintain a solid engagement state. It can be easily processed, and at the same time with a machine that removes
Since the bending streak can also be processed, the work process can be simplified, and the product can be supplied at a low cost. There is no need to apply heat when processing the product, which is a safety advantage. Since it is a product that users assemble and use by themselves, it can be stored and transported as a single sheet,
Saves space in stores and warehouses.
