Description

[Detailed description of the invention] The invention relates to a file that is convenient to carry, allows easy insertion and removal of documents such as drawings, photographs, and writing on them, and protects the documents from wind, rain, and dust. .

When carrying several documents at the same time, such as drawings used at factories or construction and civil engineering sites, fold or roll them to protect them from wind and rain, then store them in a paper tube or paper or plastic bag. Generally, it is taken out from inside.

However, it is inefficient to take the documents out of the bag each time, as it takes time to handle them, and when handling them outdoors, rainwater and dust may adhere to the documents, and wet or dirty hands may come into contact with them. In addition to disadvantages such as lack of durability due to stains, cuts, and damage, there are other disadvantages such as, for example, when writing necessary information on paper, it takes time and effort to remove the entire paper at a time, which reduces work efficiency. was accompanied by

In the present invention, a plurality of hooks are attached oppositely to the leading edges and left and right side edges of two upper and lower sheets made of transparent synthetic resin, and are also provided at the rear end of a partition sheet interposed between the upper and lower sheets. By making the binding body protrude outward from the rear end of the upper and lower sheets, and by integrally fixing the upper and lower sheets and the partition sheet at the left and right side edges of the rear end to form a unit, this file does not have the above-mentioned drawbacks of the conventional file. It was intended to provide the following.

Next, we will explain the main file and the example of the drawing.
1 and 1' are two vertically rectangular upper and lower sheets made of transparent thermoplastic synthetic resin, and the leading edge and left and right side edges of each sheet are made thicker by reducing the sheet edge and folding back the flaps. .

Then, a plurality of hooks 2 are attached at equal intervals to the lower surface of the leading edge and left and right side edges of the upper sheet 1, and the lower sheet 1'
Hooks 2' that engage with the hook 2 are attached to the upper surfaces of the leading edge and left and right side edges of the hook 2, facing each other.

3 is a transparent partition sheet made of the same material that is interposed between the upper and lower sheets 1.1'; A thick band-shaped binding body 4 is integrally formed, and this binding body protrudes outward from the rear end of the upper and lower sheets 1.1', and furthermore, the left and right side edges of this binding body 4 and the upper and lower sheets 1.1 The left and right side edges of the rear ends are high-frequency welded to form a fixed portion 5, and openings 6 are present between the rear ends of the upper and lower sheets 1, 1' and the partition sheet 3.

A plurality of main body pieces A configured in this way are superimposed, and the bound bodies 4 are aligned, and the binding string 8 is inserted into the string passing hole 7, or the bound bodies are connected to each other with hooks or fixed with clamps or the like. You will get the file.

As mentioned above, when the leading edge and left and right side edges of the upper and lower sheets 1, 1' are closed by the engagement of the hooks 2 and 2', the upper and lower sheets 1, 1' are in a state where only the rear side is opened, and the main body piece A is It becomes a bag-like substance.

Therefore, documents 9 such as drawings are inserted through the opening 6,
It is stored between the upper sheet 1 and the partition sheet 3, and between the lower sheet 1' and the partition sheet 3.

If the document 9 is horizontally long and longer than the width of the upper and lower sheets t'L1', the document inserted through the opening 6 on the upper sheet 1 side can be folded back from the tip of the partition sheet 3 to the lower sheet 1' side. good.

In addition, if each bound main piece A is made into a double-page spread, a single document can be inserted from the left and right openings, so it will fit approximately 2 times the width of the sheet.
Documents that are twice as long can be stored (see Figure 6).
Furthermore, longer documents can also be stored by folding them back toward the lower sheet 1' through the partition sheet 3.

In either case, the file is opened and closed like a book, so
You can see through the document while it is still stored.

However, if you need to write on the stored documents, you can release the hooks 2, 2' of the upper and lower sheets 1.1' and peel off the upper sheet 1 from the lower sheet 1'. 9 is exposed on the upper surface of the partition sheet 3 (see No. 5) without having to be taken out from the opening part 6, so necessary information can be written thereon.

According to the present invention, the main body piece A is composed of the upper and lower sheets 1.1' and the partition sheet 3, so it is not bulky and can be easily folded vertically and horizontally, making it compact and convenient for carrying. It is.

In addition, the entire surface of the stored documents is covered by the upper and lower sheets 1, 1' whose edges are sealed with hooks 2, 2', so there is no risk of rainwater or dust adhering to or infiltrating even when carried to construction sites etc. Therefore, it maintains durability without deterioration, staining, or tearing, and when writing on a document, the hooks 2 and 2' are disengaged and the upper sheet 1 is once peeled off from the lower sheet 1'. This saves the trouble of taking out the entire document each time, which improves work efficiency, and after writing, the upper and lower sheets can be easily closed by closing the upper sheet 1 and engaging the hooks 2 and 2' with each other.

Further, the insertion of the document 9 is not limited to the opening 6, but it is convenient that the document 9 can be inserted not only from the leading edge side of the upper and lower sheets but also from the left and right sides by releasing the hooks 2 and 2'.

In addition, in this invention, both the upper and lower sheets 1, 1' and the partition sheet 3 are made of synthetic resin and are suitable for high-frequency welding, making manufacturing extremely easy and quick.
By setting 0 (see Figure 7), there is a practical benefit of making the appearance more convenient.

In addition, this invention allows the upper and lower sheets 1 to be attached by securing the hooks 2 and 2'.
, 1', but it is also distantly related to devices that achieve the same purpose as hooks, such as Velcro tape, and of course this point also falls within the scope of free implementation of the present invention. .
