Description

[Detailed Description of the Invention] Conventionally, civil engineering and architectural drawings are large in size, so when they are copied, they are folded into 85-size or A4-size books and bound, or they are stored in files. However, when the folding is done manually, the shape is uneven and the end faces are not aligned, resulting in poor aesthetics, and the folding process requires a lot of effort.

In order to solve the above-mentioned drawbacks, the present invention makes it possible to fold the drawings uniformly and without requiring any effort.
This invention relates to the creation of a device that can improve the aesthetic appearance of bound books.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

An inverted formwork 2 is fixed on the side of the upper surface of the base plate 1 near the back side, and a straight frame 3 is fixed on an extension line of the horizontal horizontal part of the inverted formwork 2 at an appropriate interval from the inverted formwork 2. Then, reverse formwork 2 and straight formwork 3
The hinge 4 is fixed at a position near the back of the top surface of the base plate 1 at a distance from Hing the thin long plates 5, 5'5' to the hinge 4 so that the dimensions are met, and then attach the thin thin plates 6 of an appropriate length.
Notches 7, 7', 7", 7 are formed so that the four corners of the sheet can come into contact with the ends of the horizontal horizontal portions of the inverted formwork 2, and the distance between the left end of the thin board 6 and the inverted formwork 2 can be adjusted. It is made by combining the thin plate 6 and the base plate 1.

In the figure, 8 is plywood, 9 is a thin board, 10 is a drawing with the upper end folded back, 11.11' is a left and right folded vertical line, and 12 is a terminal line.

Next, the effects of the present invention will be explained with reference to embodiment figures.

When folding A2 size, A1 size, Kei size, Kei size, etc. drawings into the shape of B5 size 4 or A4 size, etc., use the base plate 8 as shown in Figure 4 and the vertical length to match the length of 85 size. The upper end of the drawing is folded downward using a thin sheet 9, and when the folded part is further below the vertically long center position of the 85-size paper, it is further folded back to the upper end as appropriate to align it.

Next, when folding the right side toward the left side, the thin long plates 5.5' and 5'' of the base plate 1 and the thin thin plate 6 are used, and the thin long plate 5.5' is used.

5" upwards, and then folded the upper end into the specified size. The left side end and the upper end of the drawing 10 are brought into contact with the inner surfaces of the inverted formwork 2 and the straight frame 3, and the thin long plate 5 is placed on the upper surface. The long thin plate 5 is rotated and placed, folded back to the left side along the right edge of the long thin plate 5, and then the thin plate 6 is placed on the top surface of the folded portion and notches 7, 7' are formed at the four corners according to the type of the original drawing. , ?", 7"' are selected appropriately and brought into contact with the end face of the horizontal horizontal part of the inverted formwork 2, and then the folded part is folded back to the right along the left edge of the thin sheet board 6, and then the thin sheet Leave the long plate 5 as it is and pull out the thin plate 6.
For the second left-right folding, place the second long thin plate 5' on the drawing again and fold it towards the left side, place the thin plate 6 on the top surface of the folded part in the same manner as the first time, and fold it towards the right side. Finally, place the third thin long plate 5'' and fold the remaining part to the left side, and then turn the drawing into three thin long plates 5.5'.

A thin long plate 5.5' which is drawn from 5.5'.

5'' and the thin plate 6 alternately, align the outer shape to the specified 85 size or A4 size shape, align the vertical lines 11 and 11' of the folded part, and align the end line 12 of the folded part with the vertical line. 1
1, 11' and approximately 1 crIL, the folded end faces are aligned and aesthetically pleasing compared to simply folding by hand, and it is easier to bind, etc., and the folding can be done more efficiently. It has the remarkable effects mentioned above, such as being able to perform various tasks.

Claims (1)

[Claims] 1. Fix the inverted formwork 62 on the side of the upper surface of the base plate 1 near the back side, and place the straight frame 3 on the extension line of the horizontal horizontal part of the inverted formwork 2 at an appropriate interval from the inverted formwork 2. Fix the hinge 4 at a position close to the upper surface of the base plate 1 at the interval between the reverse formwork 2 and the straight frame 3, and Hing the long thin sheets 5, 5 "5" to the hinge 4 so that the distance between the vertical and vertical parts of the formwork 2 is the specified size, and turn the four corners of the thin sheets 6 of an appropriate width over the sides of the formwork 2. Notches 7, 7', 7", 7"' are formed between the thin plate 6 and the base plate so that they can contact the edges of the horizontal portions and adjust the distance between the left side edge of the thin plate 6 and the reverse formwork 2. 1. A folding device for drawings, etc., which is made in combination with 1.
