BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heading portion in a file in which a plurality of continuous storage portions are disposed between a front plate and a rear plate of a cover so as to be folded in a bellows shape.

[0002]

2. Description of the Related Art Conventionally, a front plate, a bottom plate, a rear plate, and a cover plate are integrally and continuously connected between a front plate and a rear plate of a cover body. An expansion file is known in which opposed mountain folds are connected by a partition plate having a heading at the upper edge, and a synthetic resin storage body having a plurality of storage units connected in the front-rear direction is arranged. , The configuration of the heading part in the above file
As shown in FIGS. 5 and 6, on the upper edge of the partition plate a made of a synthetic resin sheet, an auxiliary piece b and a heading c having an end with a part b ′ of the auxiliary piece b are formed. Along with the auxiliary piece, the auxiliary piece is folded in two at its intermediate position,
The lower part is welded to the upper edge of the partition plate a, and the reinforcing piece b is bent at the upper edge of the partition plate a, and the lower edge and the lower edge of the auxiliary piece are welded to the partition plate a. With this configuration, the heading portion c is formed integrally with the partition plate a and the upper edge of the partition plate a is reinforced.

[0003]

However, according to the above-mentioned conventional construction, the auxiliary pieces are melted in two steps in order to form the heading part integrally and to reinforce the upper edge of the partition plate. Since it is necessary to perform the dressing process, not only does it take time and effort to produce the length, but also there is a defect that the operation of inserting and removing the heading card from the heading part is troublesome.

[0004]

SUMMARY OF THE INVENTION In the present application, a reinforcing piece and a part thereof are formed on the upper edge of a partition plate so that the welding process is partially omitted and the operation of inserting and removing the index card is facilitated. And an auxiliary piece forming the head portion having a portion at the end thereof is integrally provided, and the reinforcing piece is reinforced at an upper edge of the partition plate and the auxiliary piece is bent at an intermediate position thereof to reinforce. The lower edge is welded to the partition plate by aligning the piece and its part in the lateral direction, and the auxiliary piece is bent at one side of the heading part formed by bending, and the lower edge is cut through the cut line. It is characterized by providing a bendable free piece, preferably,
The reinforcing piece and the auxiliary piece are bent to the rear side of the partition plate and welded,
The loose piece is provided on the rear surface of the heading portion, and the free piece may be provided at the center of one surface of the heading portion, or may be provided at the left and right positions of one surface of the heading portion.

In use, a heading card is interposed in the heading portion in the same manner as in the prior art. At the time of the intervention, the free piece is bent inward so that the heading card is superimposed on the front surface. Intervene. Then, the lower edge of the heading card comes into contact with the lower edge bent portion of the loose piece, and the heading card is correctly held in the heading portion. In addition, the operation of inserting and removing the index card is performed using the window hole generated by the formation of the loose pieces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. A cover body A is made of a single synthetic resin plate in which a front plate 1, a bottom plate 2, a rear plate 3 and a cover plate 4 are integrally connected. The storage body B disposed between the front and rear plates 1 and 3 of the cover body A
It is also made of synthetic resin, and the left and right side wall plates 5 and 5 which can be folded in a bellows shape, and the mountain folds are connected to each other by welding both sides to the mountain folds opened at the left and right, and And a partition plate 7 having a flat cylindrical heading portion 6 opening at the left and right side edges at the edge portion. The front and rear surfaces of the storage body B thus configured are front and rear plates of the cover body A. The storage portions 8 are fixed to the inner surfaces of the first and third members by welding, thereby forming a continuous storage portion 8 in the front-rear direction.

The partition plate 7 is made of a transparent resin sheet, and has a reinforcing piece 9 at an upper edge thereof and a heading 6 having a portion 9 'forming a part of the reinforcing piece 9 at the edge. In the present embodiment, when the auxiliary piece is folded in two at the intermediate position, the rear face 6a of the heading portion 6 is provided.
At a position where と is provided, a loose piece 12 that is bent at the lower edge 11 via an arcuate cut line 10 is provided.

Thus, the reinforcing piece 9 is bent at the upper edge of the partition plate 7 and the auxiliary piece is bent from its intermediate position to the rear side of the partition plate 7 so that the reinforcing piece 9 and its portion 9 'are laid sideways. After matching in the directions, the lower edges of the reinforcing piece 9 and its portion 9 'are welded 13 to the rear surface of the partition plate 7, so that the upper edge is reinforced by the reinforcing piece 9 and its portion 9'. And heading 6
Are integrally formed, and the left and right side edges of the partition plate 7 thus configured have side walls 5 and 5 facing each other on the left and right.
5 is welded to the mountain fold.

In the above configuration, a heading card is interposed in the heading portion 6 as in the prior art. In this case, the loose piece 12 is bent inward, and one flat Heading card or inverted V as shown in FIG.
The heading card P bent in a letter shape intervenes so as to overlap the front surface of the free piece 12. Then, the lower edge of the heading card P comes into contact with the lower edge bent portion 11 of the loose piece 12, and in this state, the heading card P reinforces the upper edge portion 9 'of the partition plate 7.
Without being lowered to the position of the heading section 6. The entry and exit of the index card P is performed using the window hole 14 generated by the formation of the loose pieces 12.

FIG. 4 shows another embodiment of the loose piece 15, which is formed at a lower edge 17 through a slanting cut line 16 at the lower side edge of the left and right positions on the rear surface of the heading portion 6. Each of the triangular loose pieces 18 that can be bent is provided.

[0011]

As described above, according to the present invention, one welding process can be omitted due to the extremely simple structure of providing the loose pieces, which is effective in manufacturing, and the formation of the loose pieces is effective. The resulting window can be conveniently used for taking in and out of the index card. In particular, in the case of the configuration described in claim 2, since the window is located on the rear side of the partition plate, there is no fear of impairing the appearance. Has advantages.
