Description

[Detailed description of the invention] This invention relates to a file using a string. In the file of this invention, the binding string was not fixed, but the documents were inserted in opposite directions, and each was inserted into the gap between the cover and the middle sheet, and they were engaged so that they could slide, so that the binding string could hold the documents together. When you open the file without pressing it down, the spread of the document is very good.

To explain the figures, FIG. 1 shows a sheet 10 that is made of a material such as polypropylene and serves as the outermost cover in which the file of this invention is developed.The left side of the figure is the front cover 3, the right side is the back cover 5, The center corresponds to spine 4. The front cover has a folding piece 31 and a bottom plate 32
33 is an edge of the folded piece, 34 is a folded line, and 35 is a hole into which a file band tongue piece to be described later is inserted. 4 is the spine, and 41 and 42 are fold lines serving as boundaries, respectively. On the back cover 5,
A horizontal cut is made on the left side of the folding line 54, and upper and lower folding pieces 51, 51' and a central band tongue piece 5 are formed.
1''.The upper arrows indicate the direction of folding.

FIG. 2 shows an intermediate sheet 6 to be attached to the inner upper surface of the cover shown in FIG. It consists of three parts, including a back cover 63, and a spine 62 has slits 64 and 65 cut therein into which a document holder, which will be described next, is inserted. 66 and 67 are holes into which the string is inserted.

Figure 3 shows the document holder 7, with left and right side pieces 7.
1, 72, and a bottom piece 73. 74,7
5, 76, and 77 are holes through which the string is passed. Fourth
The figure shows the binding strings 1 and 2, and 11 and 12 are the heads, which, as will be described later, are locked into holes in the side pieces of the document holder 7, and the binding strings are connected by the protrusions 12 and 22 of the binding string. is designed to prevent it from coming out in the opposite direction.

FIG. 5 shows FIG. 1 folded back, and the piece 31 is folded back over the bottom piece 32 along the folding line 34, and the upper and lower edges of the overlapping portion are welded, respectively. Then, the area where the pieces 31 and 32 overlap becomes a bag, and a gap is created between them. As can be seen from the figure, the edge 33 is located above the bottom piece 32 and forms the opening of a bag.

Furthermore, the folded pieces 51 and 51' on the right side of the figure are folded back onto the bottom piece 52 of the back cover along the folding line 54, and among the overlapped parts, the upper edge of piece 51 and the lower edge of piece 51' are folded back. If these are welded together, the pieces 51 and 51' will stand on the bottom piece 52 of the back cover 5 with a gap left in between.

FIG. 6 shows how the file is constructed, with the intermediate sheet 6 placed on the cover shown in FIG.
1 between the front cover pieces 31 and 32, insert the piece 63 under the back cover pieces 51 and 51', so that the piece 62 is above the spine cover 4, and insert the piece 63 between the pieces 31 and 32 of the front cover. Weld the upper and lower edges onto the spine 4. Therefore, a gap exists between the spine 4 and the piece 62 over the entire surface except for the upper and lower edges.

Next, the document holder 7 is passed through the slits 64 and 65 of the intermediate sheet 6, and the central piece 73 is locked between the slits, that is, in the gap between the spine 4 and the piece 62 (the locking means of the document holder is not shown). (Of course, it is not limited to this example, and any arbitrary example may be used.)

In use, both side pieces 71 of the document holder 7,
Sandwich the document between 72 and tie the binding string 1 to the side piece 72
It is inserted through the hole 76 in the document and through the hole 74 in the side piece 71, and then inserted through the hole 66 in the intermediate sheet into the gap between the intermediate sheet 61 and the bottom piece 32 of the front cover. The head 11 is locked in the hole 76. The string 2 conversely connects from the hole 75 of the side piece 71 to the hole of the document and the side piece 72.
is inserted through the hole 77 in the intermediate sheet and into the gap between the intermediate sheet 63 and the bottom piece 52 of the back cover. The head 21 is locked in the hole 75. In this way, the head of the string is simply locked into the hole into which it is inserted, and the string as a whole can slide, so it does not press down on the document.

Figure 7 shows the document being bound, and the binding string 1 is attached to the side piece 72 of the document holder 7 (document 8 in the figure).
The intermediate sheet 61 passes through the hole 81 of the document 8 and the hole 74 of the side piece 71 from the hole 76 of
It is inserted through the hole 66 into the gap between the intermediate sheet 61 and the bottom piece 32 of the front cover.

Conversely, the string 2 passes from the hole 75 in the side piece 71 to the hole 82 in the document 8, passes through the hole 77 in the opposite side piece 72 (not visible in the figure), and passes through the hole 67 in the intermediate sheet to the bottom piece 52 of the back cover. It is inserted into the gap between the

FIG. 8 shows the file closed, and the band tongue piece 51'' protruding from the back cover 5 is inserted into the hole 35 of the front cover 3, thereby closing the cover so that it cannot be opened.

The file of this invention has such a structure, and since the binding strings are engaged so that they can slide through the document in opposite directions, the binding string does not forcefully hold down the document, and when the file is opened, , a file with a good spread of the document was obtained.
