Description

  The present invention relates to a folded document that can be folded and opened by pinching one end of the document with one hand.

  For the above folding document, for example, a map as disclosed in Patent Document 1 has been proposed. That is, as shown in FIG. 7, a plurality of fold lines are provided (FIG. (A)), can be folded or opened (FIG. (B)), and become small when folded (FIG. (C)). Has been proposed.

JP 05-224593

  However, although the map of Patent Document 1 is small in the folded state as shown in FIG. 7C, the entire folded shape is an elongated trapezoidal shape. However, since a normal document is a quadrangle, the shape is greatly different, and it is difficult to handle the folded map and the normal document in a naturally overlaid state, and the appearance of the overlaid state is also bad. That is, in the overlapped state, a gap is left between a portion where the long and narrow trapezoidal maps overlap and another portion, and the thickness of each portion becomes non-uniform.

  In order to solve the above problems, an object of the present invention is to provide (1) a folded document that can be folded and opened by holding one end of the document with one hand, and (2) a folded document that is rectangular in the folded state. And

In order to solve the above problems, the first invention is a folded document that can be folded and opened by pinching one end of the document with one hand, and a square document body and a diagonal line from the upper left to the lower right of the document body One mountain fold line formed in a shape, two valley fold lines having an intersection on the left side of the center of the diagonal line, parallel to the side of the square and crossing each other in a cross shape, and the two Among the two large and small squares formed by the valley fold line and the four sides of the square, and formed at the corner of the right end of the diagonal of the large square, and the two sides of the large square and the corner are made common Two mountain fold lines formed as the other two sides forming the right-end square, and the length of the side of the large square of the two large and small squares is A, and the length of the side of the small square Let B be the length of the side of the rightmost square, and C
C = AB
This is a folding document characterized by having the following relationship.

The second invention is a folded document that can be folded and opened by holding one end of the document with one hand, and a square document body and a mountain formed diagonally from the upper left to the lower right of the document body. A fold line, two valley fold lines having an intersection on the left side from the center of the diagonal line, parallel to the side of the square and intersecting each other in a cross shape, and the two valley fold lines and the square 4 Two other sides forming a right-end square that is formed at the corner of the right end of the diagonal of the large square among the two large and small squares formed by one side. Other two fold lines formed at the left corner of the square of the document main body and the left corner of the square and the corner of the square. Two mountain fold lines formed as two sides and a document book Assuming a square having a vertex at the left end of the diagonal line and the right side of the center on the diagonal line, two valley fold lines located inside the large square among the sides forming the assumed square, Two fold lines located outside the large square among the sides forming the assumed square, and the length of the large square side of the two large and small squares is A, and the side of the small square The length of the right-end square is C, the length of the left-end square side is D,
C = AB
D = B−A / 2
This is a folding document characterized by having the following relationship.

  In the description of these inventions, the concept of left and right and up and down is used, such that one diagonal fold line formed diagonally on the document body is formed from the upper left to the lower right. However, these descriptions are for convenience. In other words, if the document body is rotated 90 degrees, 180 degrees, 270 degrees, and the front and back sides are reversed, these left and right and top and bottom descriptions will not apply on the surface, but the document body If the different states are restored, the description will be correct and will not escape the technical scope of the present invention.

According to the first invention, two large and small squares and two quadrangles are formed by the two valley fold lines intersecting in a cross shape and the four sides of the square of the document body. These squares and squares are arranged symmetrically with respect to one mountain fold line from the upper left to the lower right of the document body.
To fold, one hand holds the outside corner of one quadrangle and overlaps the outside corner of the other square. Then, by one mountain fold line, the two large and small squares are each folded in half to form a triangle and overlap the other square. At this time, the end of the triangle in which the large square is folded protrudes from the top of the quadrilateral, but becomes a small triangle folded inward as the right end square and does not protrude.

At the same time, one quadrangle overlaps the other quadrangle, centering on the crossing point. In this way, it can be folded.
On the contrary, when opening, it is only necessary to pinch the outside corner of one rectangle with one hand and pull it away from the outside corner of the other rectangle.
In this way, (1) one end of the document can be pinched with one hand and folded or opened. In addition, (2) in a folded state, it becomes a quadrangle.

According to the second invention, two large and small squares and two quadrangles are formed by the two valley fold lines intersecting in a cross shape and the four sides of the square of the document body. Furthermore, the large square and the two quadrangles are divided into two by the assumed square. These squares and squares are arranged symmetrically with respect to one mountain fold line from the upper left to the lower right of the document body.

  To fold, one hand holds the outside corner of one quadrangle and overlaps the outside corner of the other square. Then, by one mountain fold line, the two large and small squares are each folded in half to form a triangle and overlap the other square. At this time, the end of the triangle in which the large square is folded protrudes from the top of the quadrilateral, but becomes a small triangle folded inward as the right end square and does not protrude. Similarly, the end portion of the triangle in which the small square is folded protrudes from the top of the quadrangle, but becomes a small triangle folded inward as the left end square and does not protrude.

At the same time, one quadrangle overlaps the other quadrangle, centering on the crossing point. Furthermore, this overlapping quadrangle is folded into two by an assumed square to become a smaller quadrangle. In this way, it can be folded.
On the contrary, when opening, it is only necessary to pinch the outside corner of one rectangle with one hand and pull it away from the outside corner of the other rectangle.
In this way, (1) one end of the document can be pinched with one hand and folded or opened. In addition, (2) in a folded state, it becomes a quadrangle.

[1] A first embodiment of the present invention is shown in FIGS.
As shown in FIG. 1, for example, a folding document 1 as a map is provided in the book 3. That is, the folded document 1 that is a rectangle in the folded state is pasted on the page 5 in the book 3 having the page 5 having the same shape as the rectangle.
FIG. 2 shows a development view of the folding document 1.

[Folding lines, etc.]
The main body 7 of the folding document 1 that is a map is a square 8. One mountain fold line 9 is formed in a diagonal line 6 from the upper left to the lower right of the document body 7. Two valley fold lines 13 having an intersection 11 on the left side from the center of the diagonal line, parallel to the sides of the square 8 and intersecting each other in a cross shape are formed. These two valley fold lines 13 and the four sides of the square 8 form two large and small squares 15 and 16. A right end square 17 is formed at the right end corner of the diagonal of the large square 15. The right end square 17 shares two sides of the large square 15 and the right end corner. The other two sides forming the right end square 17 are formed as two mountain fold lines 18.

When the folding lines 9, 13, 18 are formed in this way, two square fold lines 15, 16 and two quadrangles are formed by the two valley fold lines 13 intersecting in a cross shape and the four sides of the square 8 of the document body 7. 20, 21 are formed. These squares 15 and 16 and squares 20 and 21 are arranged symmetrically with respect to one mountain fold line 9 from the upper left to the lower right of the document body 7. A right end square 17 is formed at the lower right.
A small knob 19 is attached to the upper right of the square 8 of the document body 7 with a separate sheet so that the document can be easily picked up.

[Size]
Of the two large and small squares 15, 16, the length of the side of the large square 15 is A, the length of the side of the small square 16 is B, the length of the side of the rightmost square 17 is C,
C = AB
Have the relationship. A, B, and C are positive, and therefore A> B and A> C.

  These A, B, and C are appropriately determined in accordance with, for example, the size of the page 5 of the book 3 to be pasted. Further, there is usually a slight error when performing folding operations such as mountain folding and valley folding with the folding lines 9, 13, and 18. Such errors are allowed. This error varies greatly depending on whether the work is machine weaving, hand folding, or what the top material is.

"Effect of the embodiment"
In the above embodiment, in order to fold the document 1 from the opened state (FIG. 3A), the knob 19 provided at the outer corner of one square 20 is pinched with one hand (FIG. 3B), The operation is performed so as to be rotated largely upward in the center of the document (FIG. 3 (C)) and superimposed on the outer corner of the other square 21 (FIG. 3 (D)).

  Then, as shown in FIGS. 3B and 3C, the two large and small squares 15 and 16 are folded in half by one mountain fold line 9 to form triangles 25 and 27, respectively. Overlapping. And these two triangles 25 and 27 do not overlap each other. At this time, the end portion of the triangle 25 in which the large square 15 is folded protrudes from the top of the quadrangle 21, but becomes the small triangle 29 folded inward as the right end square 17 and does not protrude.

  At the same time, as shown in FIGS. 3B, 3 </ b> C, and 3 </ b> D, one quadrangle 20 overlaps the other quadrangle 21 around the intersection 11 that intersects in a cross shape. In this way, it can be folded into the shape of a small square (21).

On the contrary, when opening, it is only necessary to hold the knob 19 on the outer side of one of the squares 20 with one hand and rotate it upward from the center of the document and pull it away from the outer corner of the other square 21.
In this way, the knob 19 at one end of the document 1 can be pinched with one hand to be folded or opened. Further, in a folded state, it becomes a small square (21), and it overlaps neatly with page 5 of book 3.
Further, when the folding or opening operation is performed, the document 1 does not move with the weight of the book 3, and the operation is stabilized.

  Further, in the folded state, the thickness of the small square (21) document is about the thickness of the document body 7 in the main part. Therefore, the thickness becomes uniform. This is because when the two large and small squares 15 and 16 are folded in half to form the triangles 25 and 27, and the two triangles 25 and 27 do not overlap each other when they overlap the quadrangle 21. However, only the portion of the small triangle 29 in which the right end square 17 is folded inward is equivalent to six sheets of the document body 7. However, this small triangular portion has a small area. Therefore, the thickness of each part of the small square in the folded state is approximately uniform.

[2] A second embodiment of the present invention is shown in FIGS.
As shown in FIG. 4, for example, a folding document 1 as a map is provided in the book 3. That is, the folded document 1 that is a rectangle in the folded state is pasted on the page 5 in the book 3 having the page 5 having the same shape as the rectangle.
FIG. 5 shows a development view of the folded document 1.

[Folding lines, etc.]
The main body 7 of the folding document 1 that is a map is a square 8. One mountain fold line 9 is formed in a diagonal line 6 from the upper left to the lower right of the document body 7. Two valley fold lines 13 having an intersection 11 on the left side from the center of the diagonal line, parallel to the sides of the square 8 and intersecting each other in a cross shape are formed. These two valley fold lines 13 and the four sides of the square 8 form two large and small squares 15 and 16. A right end square 17 is formed at the right end corner of the diagonal of the large square 15. The right end square 17 shares two sides of the large square 15 and the right end corner. The other two sides forming the right end square 17 are formed as two mountain fold lines 18.

Further, a left end square 31 is formed at the left end corner of the diagonal line 6 of the square 8 of the document body 7. This left end square 31 has two sides in common with the corner of the square 8 and forms two mountain fold lines 33 as the other two sides.
Further, assuming a left end point 35 of the diagonal line 6 of the document body 7 and a square 39 having a vertex 37 on the right side of the center on the diagonal line 6, the inside of the large square 15 among the sides forming the assumed square 39 is assumed. The part located at 2 is defined as two valley fold lines 41. In addition, a portion located outside the large square 15 in the sides forming the assumed square 39 is defined as two mountain fold lines 43.

When the folding lines 9, 13, 18, 33, 41, 43 are formed in this way, the two valley fold lines 13 that intersect in a cross shape and the four sides of the square 8 of the document body 7 are two large and small squares 15. , 16 and two squares 20, 21 are formed. Further, the assumed square 39 divides the large square 15 and the two quadrangles 20 and 21 into two. The plurality of squares and quadrangles are arranged symmetrically with respect to one mountain fold line 9 from the upper left to the lower right of the document body 7. A right end square 17 is formed at the lower right. A left end square 31 is formed at the upper left.
In addition, a small knob 19 is attached to the upper right of the square of the document body 7 as a separate sheet so that this document can be easily held.

[Size]
Of the two large and small squares, the length of the side of the large square 15 is A, the length of the side of the small square 16 is B, the length of the side of the right end square 17 is C, and the length of the side of the left end square 31 is Let D be the length,
C = AB
D = B−A / 2
Have the relationship. A, B, C, and D are positive, so A>B> A / 2 and A> C.

  These A, B, C, and D are appropriately determined according to the size of the page 5 of the book 3 to be pasted, for example. In addition, there is usually a slight error when performing folding operations such as mountain folding or valley folding by the folding lines 9, 13, 18, 33, 41, 43. Such errors are allowed. This error varies greatly depending on whether the work is machine weaving, hand folding, or what the top material is.

"Effect of the embodiment"
In the above embodiment, in order to fold the document from the opened state (FIG. 6A), the user can pinch the knob 19 provided on the outer corner of one square 20 with one hand (FIG. 6B). The operation is performed so as to be rotated largely upward in the center (FIGS. 6C and 6D) and superimposed on the outer corner of the other square 21 (FIG. 6E).

  Then, as shown in FIGS. 6B and 6C, two large and small squares 15 and 16 are folded in half by one mountain fold line 9 to form triangles 25 and 27, respectively. Overlapping. And these two triangles 25 and 27 do not overlap each other. At this time, the end portion of the triangle 25 in which the large square 15 is folded protrudes from the top of the quadrangle 21 originally, but becomes the right triangle 17 and becomes a small triangle 29 folded inward, and does not protrude (FIG. 6 ( D)).

  Similarly, the end portion of the triangle 27 in which the small square 16 is folded protrudes from the top of the quadrilateral 21, but becomes the small triangle 45 folded inward as the left end square 31, and does not protrude (FIG. 6). (D)).

At the same time, as shown in FIGS. 6B, 6 </ b> C, 6 </ b> D, and 6 </ b> E, one quadrangle 20 overlaps the other quadrangle 21 around the crossing point 11 that intersects in a cross shape. The overlapped squares (20) and (21) are folded into two by the folding lines 41 and 43 of the assumed square 39 (FIGS. 6E and 6F), and become a smaller square (47) ( FIG. 6 (G)).
In this way, it can be folded into a small square (47).
On the contrary, when opening, it is only necessary to hold the outer corner knob 19 of one of the squares 20 with one hand and rotate it upward from the center of the document so that it is separated from the outer corner of the other square.
In this way, it is possible to fold and open the tab 19 at one end of the document with one hand. Further, in the folded state, it becomes a small square (47), and it overlaps neatly with page 5 of book 3.
Further, when folding or opening the document, the weight of the book 3 prevents the document from moving and the operation is stabilized.

  Further, in the folded state, the thickness of the small square document is about eight sheets of the document body 7 in the main part. Therefore, the thickness becomes uniform. This is because two large and small squares 15 and 16 are each folded in half to form triangles 25 and 27, and when the two triangles 25 and 27 do not overlap each other when they overlap on the quadrangle 21, only four pieces are required. Furthermore, it is folded in two to form a smaller square (47), which is 8 sheets.

  However, only the portion of the small triangles 29 and 45 in which the right end square 17 and the left end square 31 are folded inward does not need to be four pieces, but is six pieces. However, these small triangles 29 and 45 have a small area. Further, when folded into two to form a smaller quadrangle (47), the portions of these small triangles 29 and 45 hardly overlap each other. As a result, in the state of a small square (47), the portion where the triangle 29 of the right end square 17 overlaps or the portion where the triangle 45 of the left end square 31 overlaps is 6 sheets + 4 sheets, which is 10 sheets. Therefore, the thickness of each part of the small square in the folded state is 8 sheets or 10 sheets, and is approximately uniform.

In the above embodiment, the folding document 1 is a map provided in the book 3, but in other embodiments, various other document uses can be considered. For example, it may be a document provided on the back of a business card. In addition to the map, there can be many such as flyers, guides, pamphlets, and machine manuals.

  In the above embodiment, the knob 19 is made of paper. However, in other embodiments, the knob 19 can be a cloth, a tape, a string, a soft wire, a plastic, or the like. Also, various shapes can be employed, for example, a character like a Mickey mouse, a finger shape, etc.
