[Prior art]
2. Description of the Related Art Conventionally, there has been known a folding method in which a thin plate-like material such as a map can be folded simultaneously in the left-right direction and the up-down direction to make it compact.
For example, Japanese Utility Model Publication No. 56-25023 discloses a folding method shown in FIG. 12, and this folding method is known as so-called "Miura folding".
The sheet-like material folded by "Miura folding" can be expanded and contracted by a simple one-way operation of pulling the diagonal ends, and even if the expansion and contraction are repeated, the fold is unlikely to reverse, and the fold is broken It has an excellent feature of being difficult. On the other hand, a sheet-like material folded by "Miura folding" has a characteristic that it cannot be partially expanded and contracted.
When performing “Miura folding” on an unfolded sheet material, it is necessary to make a fold on the entire sheet material at the same time because of the property that it cannot partially expand and contract. It is not easy to attach.
Conventionally, a flat sheet-like material is scored with a press or the like and then creased manually.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In each of the drawings, common portions are denoted by the same reference numerals, and redundant description is omitted.
[0029]
A sheet-like material folding jig according to an embodiment of the present invention will be described. FIG. 1 is a plan view of an example of a sheet-like material. FIG. 2 is a rear view of the embodiment of the present invention. FIG. 3 is a plan view of the embodiment of the present invention.
[0030]
The sheet material folding jig is a jig for forming a desired fold on the sheet material.
First, a desired fold will be described.
For example, the desired creased sheet material is paper folded by the so-called "Miura folding" method.
"Miura folding" will be described by taking as an example a case where a thin sheet material placed in the orthogonal XYZ space is folded.
"Miura folding" means that when the sheet-like material is developed on an XY plane, it is composed of a plurality of plane areas where adjacent ones share sides and corners with each other, and at least does not have an outer peripheral edge The plane area is a parallelogram, and the X sides, which are sides along the X axis, are connected to form a straight X-ray, and the Y sides, which are sides along the Y axis, are alternately bent and connected to form a zigzag Y line. "Folding" in which the X side alternates between mountain folds and valley folds alternately along the X-ray, while the zigzag Y-lines arranged along the X-ray alternately alternates between mountain folds and valley folds. One.
The mountain fold is a fold in which the fold is convex when viewed from one surface (for example, the surface), and the mountain fold line is a fold line obtained by the mountain fold.
The valley fold is a fold in which the fold is concave when viewed from one surface (for example, the surface), and the valley fold line is a fold line of the valley fold.
Attention is paid to an intersection where two X sides and two Y sides are gathered in this manner. When the two Y sides are mountain-folded, the intersection angle between the two Y sides is 90 degrees. The X side on the side exceeding the fold is a mountain fold, and the X side on the opposite side is a valley fold. If two Y sides are valley-folded, the X side on the side where the intersection angle of the two Y sides exceeds 90 degrees is a valley fold, and the opposite X side is a mountain fold.
[0031]
Here, a case where a map, which is a rectangular quadrangular thin plate-like material, is folded will be described as an example. Further, the description will be made on the assumption that the XY plane is horizontal and the surface is folded upward.
A parallelogram is a quadrilateral in which a pair of opposite sides are parallel, the length of the X side is a, the length of the Y side is b, and the intersection angle between the X side and the Y side is a right angle. Description will be made assuming that the angle is more inclined by θ degrees.
FIG. 1 is a diagram showing a state in which the folded map is expanded again, and is a thin plate-like material (here, 8 sheets in the X-axis direction and 5 sheets in the Y-axis direction) composed of a total of 40 plane regions. Map), of which 30 plane regions excluding both ends in the X-axis direction are parallelograms.
[0032]
Next, a sheet-like material folding jig according to an embodiment of the present invention will be described.
The sheet-like material folding jig is a jig for forming a desired fold on a sheet-like material (for example, paper, plastic sheet, or the like), and includes a front jig 10 and a back jig 20.
Since the sheet-like material 1 is sandwiched between the front jig 10 and the back jig 20 using a sheet-like material folding jig and creased, for convenience of explanation, the upper surface of the sheet-like material is set to the front surface and the lower surface is set to the lower surface. The jig arranged on the front surface was called a back jig, and the jig arranged on the back surface was called a back jig 20.
[0033]
The front jig 10 includes a plurality of front plate members 11 and a front sheet member 12.
The front plate member 11 is, for example, a thin (for example, 0.3 mm thick) stainless steel plate or a plastic plate, and is continuously connected to a boundary arranged in a similar manner to the fold.
Here, the pitch interval of the boundary is slightly larger than the pitch interval of the fold. Further, the similarity ratio between the fold and the boundary in the X-axis direction or the Y-axis direction changes to a degree that does not cause a practical problem for each operation due to the procedure of the operation of forming the fold.
The front sheet member 12 is a bendable sheet member in which one surface of the plurality of front plate members 11 is connected across a boundary.
For example, the front sheet member 12 is a bendable sheet member that is attached to one surface of the plurality of front plate members 11 across a boundary. In particular, it is preferable that the sheet-like members have intersecting fibers. For example, the sheet-like members are cloth and cotton cloth. It is particularly preferred that the fibers intersect at the boundaries.
Further, for example, the front jig 10 is made of a card board on which a plastic sheet is laminated, and the front sheet member 12 is a thin portion formed by pressing the card board along a boundary. Is the rest.
Also, for example, the front jig 10 is made of a plastic plate (for example, 0.5 mm thick), and the front sheet member 12 has a small thickness formed by pressing, melting or cutting the plastic plate along the boundary. And the top plate member 11 is the remaining part.
[0034]
In particular, when the front jig 10 is viewed from the side opposite to the one surface to which the front sheet member 12 is connected, the adjacent front plate members 11 at the boundary of the valley fold are separated by a desired gap G (for example, 2 mm). It is preferable that the front plate members 11 adjacent to each other at the boundary of the mountain fold are arranged without gaps.
The desired gap G is selected to be an optimum value according to the material and thickness of the sheet-like material to be creased. For example, if the sheet material is paper and the thickness is large, the gap G is selected in the range of 2.0 mm to 3.0 mm in 0.2 m units.
FIG. 2 shows that the forty front plate members 11 are eight in the X direction and five in the Y direction and are arranged in a grid pattern, and one front sheet member 12 is formed of forty forty front plate members 11. It shows that it is affixed to the whole.
[0035]
The back jig 20 includes a plurality of back plate members 21 and a back sheet member 22.
The back plate member 21 is, for example, a thin (for example, 0.3 mm thick) stainless steel plate or a plastic plate, and is connected to bendable at a boundary arranged in a manner similar to the fold.
Here, the pitch interval of the boundary is slightly larger than the pitch interval of the fold. Further, the similarity ratio between the fold and the boundary in the X-axis direction or the Y-axis direction changes to a degree that does not cause a practical problem for each operation due to the procedure of the operation of forming the fold.
The back sheet member 22 is a bendable sheet member in which one surface of the plurality of back plate members 21 is connected across a boundary.
For example, the back sheet member 22 is a bendable sheet member that is attached to one surface of the plurality of back plate members 21 across a boundary. In particular, it is preferable that the sheet-like members have intersecting fibers. For example, the sheet-like members are cloth and cotton cloth. It is particularly preferred that the fibers intersect at the boundaries.
Further, for example, the back jig 20 is made of a card board on which a plastic sheet is laminated, and the back sheet member 22 is a thin portion formed by pressing the card board along a boundary. Is the rest.
Further, for example, the back jig 20 is made of a plastic plate (for example, 0.5 mm thick), and the back sheet member 22 has a small thickness formed by pressing, melting or cutting the plastic plate along a boundary. And the back plate member 21 is the remaining portion.
[0036]
In particular, when the back jig 20 is viewed from the side opposite to the one surface to which the back sheet member 22 is connected, the adjacent back plate members 21 at the boundary of the valley fold are interposed via a desired gap G (for example, 2 mm). It is preferable that the back plate members 21 adjacent to each other at the boundary of the mountain fold are arranged without gaps.
The desired gap G is selected to be an optimum value according to the material and thickness of the sheet-like material to be creased. For example, if the sheet material is paper and the thickness is large, the gap G is selected in the range of 2.0 mm to 3.0 mm in 0.2 m units.
FIG. 3 shows that 40 back plate members 21 are arranged in a grid pattern with eight in the X direction and five in the Y direction, and one back sheet member 22 is formed of 40 back plate members 21. It is shown attached to the whole.
