BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing file for storing drawings or relatively large sheets (hereinafter simply referred to as drawings) without folding them.

[0002]

2. Description of the Related Art Generally, a drawing file of this kind is constructed as shown in FIG.
As shown in FIG.
2, the left and right covers 14 and 16 are formed, and the left and right edges and the upper and lower edges of the cover body 10 are folded at the folding lines 1
8, 20, 22, 24, left and right and up and down folded pieces 2
6, 28, 30, 32 can be folded sequentially (see Fig. 8)
When the both covers 14 and 16 are folded, the partition lines 10, 20, 22 and 24 are respectively provided at the folding lines 18, 20, 22 and 24.
a, 26a, 28a, 30a, 32a are formed (see FIGS. 9 and 10) to accommodate a relatively large number of drawings.

In such a configuration (especially,
In relatively large drawing files), the material is made of lightweight and tactile cardboard so that the drawing can be easily moved in and out without damage. Preferably, each folded piece is provided with holding means for holding it in a half-open folded state, and on both right and left covers, engaging means for engaging it in a folded state are provided. That is, in the illustrated drawing file, the left and right folded pieces 26 and 28 and the upper and lower folded pieces 30 and 32 are respectively provided with engagement notches 34 and hook-and-loop fasteners 3 at both ends thereof.
6, an engagement notch 38, and a window hole 40 are provided.
In this case, when the left and right folded pieces 26 and 28 are expanded, the engagement notch 34 slides on the inner surfaces of the upper and lower folded pieces 30 and 32 to expand the same, and engages with the engagement notch 38. When the folded pieces are stopped (FIG. 10) and held in a half-open folded state, the holding means 42 is formed. On the other hand, upper and lower folded pieces 3
In the state where 0 and 32 are folded on the left and right folded pieces 26 and 28 (FIG. 8), the hook-and-loop fastener 36 is exposed from the window hole 40 to constitute the engaging means 44, and the left and right covers 14 and 16 are When folded, they are engaged in place. In addition, reference numeral 46 in the figure indicates a folded portion provided at a portion corresponding to the folded portion (partition wall 10a) of both the left and right covers 14,16.
