Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drawing folding ruler plate.

[Conventional technology]

Generally, in architectural drawings and mechanical drawings, the one-item, one-leaf drawing style, in which only one item is drawn on one sheet of paper, is often adopted as a drawing format. For this reason,
The number of drawings becomes enormous in the case of machinery that has a large number of parts, or civil engineering and architectural drawings that require different drawings for each process. These drawings are usually folded and bound to the size of number 4 in column A or number 4 or 5 in column B. That is, according to the JIS drafting general rules, when folding a drawing with a dimension of A row larger than A row No. 4, it is standard to fold it to the size of A row No. 4. For the paper in row B, fold the paper larger than row B, number 4, to the size of row B, number 4.
A drawing that is larger than number 5 in row B is folded to the size of number 5 in row B. However, there is no set procedure for folding the drawings, and the folding process is done by hand, for example, by overlapping a paper pattern of a predetermined size at a predetermined position on the drawing for each drawing, and then folding the drawings vertically and horizontally. The procedure used is to index the position of the line and fold it to a predetermined size based on the index line.

[The problem that the idea attempts to solve]

However, with this conventional method, the reference paper and the drawing do not overlap accurately, the finished dimensions after folding vary, and the edges of the drawings that are bound together are uneven and unsightly. There is.

In addition, it takes time and effort to overlap the sheets and drawings one by one and find the folding reference line.
There is a problem of low efficiency.

The present invention has been made in consideration of the above circumstances, and aims to provide a drawing folding ruler plate that can accurately fold drawings into predetermined dimensions in a short time.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a sheet whose size is larger than the size of the paper, a periphery surrounding a space with the size of the paper protrudes from one side of the sheet, and a ruler is fitted at a predetermined position on the periphery. Form a matching groove.

In the present invention, the sheet may be a soft sheet such as a vinyl sheet, or a hard sheet such as a metal plate or a plywood sheet.

Further, the peripheral edge may be formed integrally with the same material as the sheet, or may be formed separately from the same material as the sheet or a different material and then fixed to the sheet.

[Effect]

In the drawing folding ruler plate of the present invention, by placing the drawing in a space surrounded by a groove formed at a predetermined location on the periphery and fitting the ruler into the groove, the folding position can be determined instantly and accurately. Served. and,
By folding the drawing along the side edges of the ruler, the drawing can be accurately folded to a predetermined size.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a plan view of a folding ruler plate for number 2 in row A according to an embodiment of the present invention, and FIG. 2 is a side view thereof.

This drawing folding ruler plate includes a vinyl sheet 1 and a vinyl peripheral ridge 2 provided along its periphery, and linear rulers 3 are fitted at predetermined positions of the peripheral edge ridge 2. A groove 4 is formed for this purpose. Each groove 4 is formed vertically or horizontally at a position of 297 mm from the lower edge of both the left and right peripheral edges 2a, 2b, and at a position of 110.5 mm and 210 mm from the left end of both the upper and lower peripheral edges 2c, 2d, respectively.
297mm from the lower edge of and from the left edge of the lower peripheral edge 2d
It is formed at a position of 297 mm in the direction of an inclination of approximately 45° connecting these two locations. Note that all of these grooves 4 are formed to have the same width.

Furthermore, the width of the straight ruler 3 fitted into these grooves 4 is set to be the same width as the grooves 4, but
It is not necessary to make it the same width as groove 4.

Next, the procedure for folding a drawing using this drawing folding ruler plate will be explained based on FIGS. 3a to 3e.

First, as shown in Figure 3a, place the drawing face up in the space surrounded by the periphery 2 of this folded drawing ruler plate, and its lower edge is placed on the lower periphery 2d and its left edge is placed on the left periphery 2a. Place the straight ruler 3 so that they are in contact with each other, and insert the straight line ruler 3 into the horizontal grooves 4 on both the left and right peripheral edges 2a and 2b.
, and fold the upper drawing part P1 from the upper edge of the linear ruler 3 so that it overlaps the front side of the lower drawing part. Next, as shown in Figure b,
Refit the straight ruler 3 into the diagonal groove 4 on the left peripheral edge 2a and the diagonal groove 4 on the lower peripheral edge 2d, and insert the triangular part P in the lower left drawing from the diagonally lower side edge of the straight ruler 3.
2 is folded back so as to overlap with the front side of the other part of the portion P1 of the drawing that was folded earlier (on the drawing, the front side of the paper).
After that, as shown in Figure c, the straight line ruler 3 is refitted into the vertical groove 4 of 210 mm from the left end of both the upper and lower peripheral edges 2c and 2d. Fold it so that it overlaps the front side of the drawing on the left side. Furthermore, as shown in Figure d, the straight ruler 3 was refitted into the vertical groove 4 of 110.5 mm from the left end of both the upper and lower peripheral edges 2c and 2d.
A portion P4 on the left side of the left edge of the linear ruler 3 of the portion folded back to the front side of the drawing is folded back so as to overlap with the front side of the right side portion. After that, as shown in Figure e, fit the straight line ruler 3 into the vertical groove 4 of 210 mm from the left end of both the upper and lower peripheral edges 2c and 2d, and fit the straight line ruler 3 in the part of the drawing that has been folded back to the right side. Fold the part P5 on the right side from the right edge so that it overlaps the front side of the part shown in the drawing on the left side. As a result, the drawing is folded to exactly the size of number 4 in row A, leaving a 25 mm binding margin on the left edge.

[Effect of idea]

As described above, according to the drawing folding ruler plate of the present invention, the drawing can be folded in a short time by placing the drawing on the part of the sheet surrounded by the periphery and fitting the straight ruler into the groove on the periphery. accurately determined. By folding the drawing along the side edge of the linear ruler, the drawing can be folded accurately to a predetermined size in a short time. Therefore,
When folded drawings are bound using the drawing folding ruler plate of this invention, the size of each leaf is accurately aligned, so the edges of the bound drawings are neatly aligned and look good. Become.
