Description

[Detailed description of the invention] The present application relates to a file suitable for storing floppy disks, etc., in which a plurality of storage pockets are vertically offset and arranged in a stepped manner, and in particular, the file is designed to prevent welded portions from stacking in a stacked manner. This configuration prevents the welded portion from becoming locally thick and improves the appearance of the file.The embodiment will be described in detail below with reference to the drawings. Doors 3 and 4 are placed on the left and right positions so as to have the back 2 of the
A file body formed by extending through the bent part 5,
In this example, a core plate is interposed between two sheets made of vinyl chloride, and the periphery of the core plate and the boundary between the doors 3, 4 and the back portion 2 are welded 6. 7, 8, and 9 are pocket parts arranged on the inner surface of one door 3, and 10, 11, and 12 are pocket parts arranged on the inner surface of the other door 4. The pocket component pieces 7' to 12' are made of polyvinyl chloride film in the shape of a rectangular rectangle of equal size with the width matching the width of the door, and the pocket component pieces 7' to 12' arranged in the upper and middle stages are As is clear from FIG. 3, ', 10' and 11' have notches 7a and 7b, 8a and 8b, and 10a located downwardly along both side edges, leaving the upper 1/3.
10b, 11a, and 11b are provided, and in this example, the widths of the notches 7a, 8a, 10b, and 11b are made equal, and the width of the notches 10a, 11
This figure shows a case in which the widths of the notches 7a and 8b are made slightly larger, and the widths of the notches 7a and 8b are made larger than this.

On the inner surface of one door 3, the upper left and right side edges of the middle pocket component piece 8' are located at the upper half positions of the left and right notches 7a, 7b of the upper pocket component piece 7' (thereby, The lower halves of the left and right notches 7a and 7b of the upper pocket component piece 7 and the middle pocket component piece 8
The upper halves of the left and right notches 8a and 8b match),
In addition, the left and right side edges of the lower pocket component piece 9' form a notch 8 that matches the lower halves of the notches 7a and 7b.
a, 8b, and the pocket components 7', 8', 9' so that their lower edges coincide with the lower edge of the door 3.
In this state, the other three pocket components except the upper left and right side edges of the upper and middle pocket components 7' and 8', their lower edges 7c and 8c, and the upper edge of the lower pocket component 9' Weld the peripheral edges 9c to the door 3, respectively,
Similarly, for the other door 4, by welding the upper, middle, and lower pocket component pieces 10', 11', and 12' at the required locations, the doors 3 and 4 are assembled as shown in FIG. Pocket portions 7 to 12, which open at upper edges 7d to 12d, are provided on each inner surface of the pocket.

In the above, the widths of the notches 7a, 8b and 10a, 11a located on the back 2 side are differentiated into larger and smaller widths because the band-shaped indexing piece 13 is slightly deviated laterally in the middle part of the outer surface of the file main body 1. This is to prevent the welded portions 13c on both longitudinal edges of the indexing piece 13 from matching with the welded portions of the pocket component piece to the file body 1 when the indexing piece 13 is provided with a flat surface. As a result, reliable welding can be achieved.

Furthermore, in the above embodiment, three pockets are provided on the inner surface of each door.
We have described the case where the pockets are arranged in tiers, but if the pockets are arranged in two tiers, the length of the notch provided on the left and right side edges of the upper pocket component will be approximately 1/2 of the width, and the pocket portion will be arranged in 4 tiers. In this case, the length of the notch is approximately 3/4 of the vertical width, and the length of the notch is set to correspond to the number of stages of the pocket portion arranged on the inner surface of the door.

As described above, according to the present application, pockets are provided on the inner surfaces of both doors, which is effective when placing floppy disks and the like on a bookshelf to organize them. Since a pocket component piece having a width matching the width of the pocket component is used, the inner surface of the door can be effectively used for forming the pocket part, and the side edges of the pocket component piece are welded to the edge of the file main body. These side edges can be aligned at the edge, and since both side edges of the heading piece are welded to the outer surface of both doors at a position closer to the back than the notch side edge of the pocket component piece, the welded parts on both sides of the heading piece are ,
There is no overlap with the side edge welded area and the lower edge welded area of the pocket component piece, so there is no risk of the product becoming wavy or locally thick, and the shape is good, and the heading piece Since each pocket component piece is directly welded to the surface of the file main body, the welding is reliable and the welding work is easy.

[Brief explanation of drawings]

The drawings show an embodiment of the present invention, and FIG. 1 is an overall internal view with a portion cut away, FIG. 2 is an enlarged bottom view with a portion omitted, and FIG. 3 is a plan view of a pocket component. In the figure, 1 is the file main body, 3 and 4 are the doors, 5 is the bent part, 7 to 12 are the pocket parts, 7' to 12' are the pocket components, and 7a, 7b to 12a, 12b are the notches.

Claims (1)

[Scope of utility model registration request] On the inner surface of each door of the file body, which has a foldable door extended on the left and right side edges of the back, there is a cutout on the left and right sides that has a width that matches the width of the door and that extends downward leaving the upper part. The pocket structure is formed by forming a plurality of pocket component pieces and sequentially arranging the plurality of pocket component pieces offset in the vertical direction so that the upper parts do not overlap each other, and welding each lower edge to the inner surface of the door, and without forming cutouts on the left and right sides. The bottom pocket component piece that has the same width as the bottom pocket piece,
Arrange them so that they do not overlap with the upper part of the pocket component in the previous stage, and weld their lower edges to the lower edge of the inner surface of the door. A plurality of pockets are provided by welding the side edges to the inner surface of the door, and a heading piece wider than the width is superimposed on the outer surface of the back of the file main body, and both side edges are
A file characterized in that the file is welded to the outer surface of both doors at a position on the back side of the notch side edge of the pocket component piece.
