Description

  The present invention relates to origami, and in particular, relates to origami in which folding lines indicating the folding method and folding order are pre-printed and can be easily played without referring to a manual.

  Origami is a part of Japanese culture, but “crane” and “balloons”, which have been folded since ancient times, are less familiar to children as a theme, and are also difficult for adults to fold and tend to be forgotten gradually. . Therefore, recently, origami has been considered for the purpose of handing down or spreading origami. The origami has been devised so that it can be easily folded without referring to a manual.

As the origami as described above, for example, two types of fold lines indicating how to fold a mountain fold or a valley fold, and a fold order number indicating a fold order indicating which fold line to fold next, are provided as folding instructions. "Origami" that has been printed in advance on paper is proposed. According to such origami, it can be folded into a predetermined theme shape by sequentially folding according to the folding order number with folding lines and folding methods according to the line type.
Utility Model Registration No. 3085035

  By the way, in the origami on which the guide indicating the folding order and the folding method as described above is printed, for example, when folded a plurality of times, the next folding operation can be performed on a part that overlaps a part when viewed from one side or an adjacent part. There may be a fold line that must be folded at the same time. In this case, although the line types of these folding lines are the same, the folding order number is usually printed so as to be displayed only on the folding line of one part. Therefore, there is a problem that it is difficult to determine whether or not the folding lines of these different parts are folded together.

  Of course, as for the fold line that folds together at the same time as described above, the same folding order number can be written for each part. However, those with complicated shapes have a large number of folds, and a large number of fold lines appear in each part formed in the middle folding process, and from the viewpoint of design, the folding order code is in the folded state. Since it is arranged so that it does not appear on the front side, when trying to display the folding order number on all the folding lines of each part as described above, the folding lines and folding order codes are densely packed in a narrow area, and as a result, It may be difficult to select a fold line, or the fold line may be mistaken.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is an origami in which a folding line indicating a folding method and a folding order are pre-printed, and can be folded more easily and accurately. Another object is to provide an improved origami.

  In order to solve the above problems, the origami of the present invention is an origami on which two types of fold lines indicating the folding position and the folding method and a folding order code indicating the folding order of the folding lines are printed, The fold line is color-coded in multiple colors, and the fold lines that appear in one part and the other part by the second and subsequent folding operations and simultaneously fold in the same manner in the subsequent folding operations are color-coded. It is characterized by.

  That is, in the present invention, two types of fold lines representing mountain folds and valley folds and a fold order code are printed along with the fold lines, and among fold lines appearing at a plurality of parts simultaneously in the middle folding process, Each fold line is color-coded so that the fold lines that must be folded at the same time in the same folding method are the same color, so that any one of the same type of fold lines that fold together at different parts Even if the fold order code is added, the fold line that folds together in the next and subsequent folding operations can be identified immediately.

  According to the origami of the present invention, the fold line of the same color that appears in one part and the other part by the second and subsequent folding operations can be identified as the folding line that simultaneously performs the same folding in the subsequent folding operations. It can be folded more easily and accurately. In addition, when performing the second and subsequent folding operations, the folding lines of the same color in one part and the other part appearing by the folding operation are accurately folded using these folding lines as a guideline. Therefore, it can be folded up even more beautifully.

  An embodiment of origami according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an unfolded state of an example of origami according to the present invention. 2 to 6 are a front view and a rear view, respectively, showing a folding process halfway after performing the first to fifth folding operations on the origami of FIG. FIG. 7 is a front view and a rear view showing the folded state after the sixth folding operation is performed on the origami of FIG. In the following embodiment, origami with the theme of “rabbit face” will be described as an example.

  As shown in FIG. 1, the origami of the present invention is usually formed into a square planar shape, and on one surface thereof, two types of folding lines (1) to (1) to indicate folding positions and folding methods (mountain folding, valley folding). (6j) and folding order codes (codes indicated by “maru 1” to “maru 6”) indicating the folding order of these folding lines are printed. Moreover, the folding lines (1) to (6j) are color-coded in multiple colors.

  The fold lines (1) to (6j) are provided for the purpose of instructing the folding position so as to fold along the fold line, and for the purpose of instructing whether to fold in a mountain fold or a valley fold. Two types of fold lines (1) to (6j) are used. For example, when the folding method is a mountain fold, it is drawn with a dashed line, and when it is a valley fold, it is drawn with a dotted line.

  The above folding order code is a code indicating the order in which the folding line is used in the next folding operation, and is generally represented by a number. The folding order code may be other codes such as alphabets and Japanese syllabary as long as the folding order can be identified. Such folding order codes are provided at positions where they are attached to the folding lines (1) to (6j) and do not appear on the front side in the folded state (see FIG. 7A).

  Furthermore, the folding lines (1) to (6j) are color-coded in multiple colors according to the folding order, for example. That is, the colors are classified into multiple colors so that folding lines of different colors are folded for each folding operation. In the example shown in FIG. 1, the folding lines (1) to (6j) are color-coded into six colors in order to perform the folding operation six times as will be described later. Thereby, the fold line used in the next folding operation can be identified more clearly. In addition, in the present invention, the second and subsequent folding operations appear in one part and the other part (for example, the parts (A1) and (A2) in FIG. 3B) and the next and subsequent folding operations. At the same time, folding lines (for example, reference numerals (4c) and (4a) in FIG. 3B) that perform the same folding are color-coded in the same color.

  In the origami “Rabbit Face” shown in FIG. 1, the fold lines (1) to (6j) are drawn on a square sheet as follows. That is, the fold line (1) is drawn at the position of one diagonal line that bisects the paper surface. Fold lines (2a), (3a), (4a), (4d), (5a), (5d), (6a), (6g), (6h), (6i), (6j) It is drawn in one right-angled isosceles triangular region (region below the drawing) divided by 1).

  Among the fold lines, the fold line (2a) is drawn in parallel to the fold line (1) at a position separated from the fold line (1). The fold line (3a) is drawn in parallel to the fold line (1) at the corner of the square paper (the right angle portion of the right isosceles triangle) spaced from the fold line (1). The fold line (4a) is drawn at a position connecting the center of one side of the right-angled isosceles triangle (left side of the inverted triangle below the drawing) and the center of the fold line (2a) divided by the fold line (2a). It is. The fold line (4d) is drawn perpendicularly to the fold line (4a) from the center of the fold line (2a) toward the fold line (1). The fold line (5a) is a position connecting the center of the other side of the right-angled isosceles triangle (the right side of the inverted triangle below the drawing) and the center of the fold line (2a) separated by the fold line (2a). It is drawn in. The fold line (5d) is drawn perpendicularly to the fold line (5a) from the center of the fold line (2a) toward the fold line (1).

  The fold lines (6a), (6g), (6h), (6i), and (6j) are lines constituting the other three sides of the square with a part of the center of the fold line (1) as one side. The fold line (6a) is drawn and is parallel to the fold lines (1) and (2a) and is a fold line (1) by a distance twice the distance between the fold lines (1) and (2a). It is drawn across the fold line (4a) and the fold line (5a) at a position away from. The fold line (6g) constitutes a half part of the length of one side from the fold line (6a) to the fold line (2a) of one side of the square connecting the fold line (6a) and the fold line (1). The fold line (6h) is the other half of the length of one side from the fold line (2a) to the fold line (1) of one side of the square. It is drawn as a constituent line. The folding lines (6i) and (6j) constitute the remaining one side of the square and are drawn as lines parallel to the folding lines (6g) and (6h).

  On the other hand, the folding lines (2b), (3b), (4b), (4c), (5b), (5c), (6b), (6c), (6d), (6e), (6f) The other right-angled isosceles triangle area (the upper area in the drawing) separated by the line (1) is drawn, and these fold lines are respectively folded around the fold line (1). Lines (2a), (3a), (4a), (4d), (5a), (5d), (6a), (6g), (6h), (6i), drawn at positions symmetrical to (6j) It is. And each said folding line (1)-(6j) is set so that a line type, a color, and a folding order may be shown, for example in the following table | surfaces.

  The origami of the “rabbit face” shown in FIG. 1 can be folded by performing the following folding operations in order as shown in FIGS. 2 to 7, each of the partial drawings (a) is a view showing the front side surface (design surface), and the partial drawing (b) is a view showing the back side surface.

  First, as the first folding operation, in the state shown in FIG. 1, the center of the origami sheet is folded in a mountain at the folding line (1) (black one-dot chain line) to which the folding order code “maru 1” is attached. A triangle as shown in Fig. 2 is formed. Then, as shown in FIG. 2B, the back surface is turned up. Next, as the second folding operation, from the state shown in FIG. 2B, a fold line (2a) (red dotted line) to which the folding order code “maru 2” is attached is used to make the vicinity of the base of the triangle a valley fold. Thus, a substantially bowl shape as shown in FIG. 3 is formed. And as shown in FIG.3 (b), the surface of a back side is turned up.

  In the origami of the present invention, as shown in FIG. 3 (b), when the second folding operation is performed, the folding line (4c) appearing in one part (A1) of the ship shape and the triangular shape The fold line (4a) appearing in the other part (A2) is drawn as a dotted line and colored in yellow as a fold line that simultaneously folds in the subsequent folding operation. In addition, the fold line (5c) appearing in the one part (A1) and the fold line (5a) appearing in the other part (A2) are fold lines that simultaneously perform the same folding in the subsequent folding operation. , Each is colored green with a dotted line.

  Therefore, in the origami of the present invention, the folding accuracy can be confirmed by looking at the fold lines (4c), (4a), (5c) and (5a). That is, if the yellow fold line (4c) and the fold line (4a) of the same color and the green fold line (5c) and the fold line (5a) of the same color are aligned with each other, It can be determined that the first and second folding operations have been performed accurately, and if the first and second folding operations are not aligned, it can be determined that the second folding operation has not been performed correctly. If the above folding lines are not aligned, the folding operation up to the second time is performed again.

  Subsequently, as the third fold operation, the fold line (3a) (blue dotted line) to which the fold order code “Maru 3” is attached is folded from the state shown in FIG. Thus, a substantially hat shape as shown in FIG. 4 is formed. Further, as the fourth folding operation, from the state shown in FIG. 4 (b), the fold line (4a), (4c) (yellow dotted line) with the folding order code “Maru 4” is substantially hated. One ear part of the rabbit as shown in FIG. At that time, in the origami of the present invention, as described above, the fold line (4c) appearing in one part (A1) and the fold line (4a) appearing in the other part (A2) by the second folding operation are respectively shown. It is drawn with a dotted line and colored in yellow (see FIG. 4B). Therefore, when performing the fourth folding operation, the folding lines (4a) and (4c) can be immediately identified as folding lines that simultaneously perform the same folding, that is, folding lines that are folded together.

  Next, as the fifth folding operation, the above-described folding lines (5a) and (5c) (green dotted lines) to which the folding order code “Mal 5” is attached from the state shown in FIG. The other ear part of the rabbit as shown in FIG. 6 is created by making the other hat-shaped part of the substantially hat shape into a valley fold, and two ears protrude from the upper corners of the rhombus. At that time, in the origami of the present invention, as described above, the fold line (5c) appearing in one part (A1) and the fold line (5a) appearing in the other part (A2) by the second folding operation are respectively shown. It is drawn with a dotted line and is color-coded in green (see FIGS. 4B and 5B). Therefore, when performing the fifth folding operation, similarly to the fourth folding operation, the folding lines (5a) and (5c) are simultaneously folded in the same folding manner, that is, folded together. It can be immediately identified as a line.

  When the fifth folding operation is performed, as shown in FIG. 6 (a), the fold line (6b) (orange one-dot chain line) to which the folding order code “Mal 6” is attached is a rhombus. Appears in the lower corner. And when it turns over as shown in FIG.6 (b), the fold line (6e) which appears in one site | part (C1) and the fold line (6c) which appears in another site | part (C2) by the 5th folding operation. Each is drawn with a dotted line and colored orange. Accordingly, in the origami of the present invention, the accuracy of folding up to the fifth time can be immediately confirmed by looking at the fold lines (6e) and (6c) as in the case described above.

  Next, from the state shown in FIG. 6B, as the sixth folding operation, the lower corners of the rhombus are folded into valley folds at the fold lines (6e) and (6c) (orange dotted line). Even in this case, in the origami of the present invention, as in the fourth and fifth folding operations, the folding lines (6c) and (6e) are simultaneously folded in the same folding manner, that is, together. Can be immediately identified as a fold line. Then, by performing the sixth folding operation, it is possible to weave a “rabbit face” as shown in FIG.

  As described above, in the origami paper of the present invention, two kinds of folding lines (1) to (6j) representing mountain folds and valley folds and fold order codes “Maru 1” to “Maru 6” are printed in addition thereto. Of the folding lines appearing at a plurality of parts at the same time in the middle folding process, for example, the parts indicated by reference numerals (A1) and (A2) (see FIG. 3 (b) and FIG. 4 (b)), The fold lines (4c) and (4a) and the fold lines (5c) and (5a), which must be folded simultaneously by the operation in the same folding method, are color-coded into the same colors.

  Therefore, according to the present invention, the folding order code is applied to only one of the folding lines (4c) and (4a) of the same kind of different parts (A1) and (A2), and the folding lines (5c) and (5a). By adding “maru 4” and “maru 5”, it can be immediately identified as a fold line to be folded together in the next and subsequent folding operations, and can be folded more easily and accurately. In addition, for example, when the second folding operation is performed, the folding lines (4c) and (4a) of the same color and the folding lines (5c) of the one part (A1) and the other part (A2) appearing by the folding operation. ) And (5a) so that there is no deviation, the fold lines (4c) and (4a), and the fold lines (5c) and (5a) can be folded accurately, so that it can be folded even more beautifully. I can do it.

  Moreover, in the origami of this invention, as shown to Fig.7 (a), the pattern may be printed in the site | part which appears on the front side in a folded state. Specifically, as shown in FIG. 1, at a substantially central portion of a right-angled isosceles triangle (triangle shown in FIG. 2 (a) formed by the second folding operation) divided by a fold line (1). “Eye and nose” are drawn in color, and “ears” are drawn in color near the bottom ends of the right isosceles triangle. Then, when folded up as shown in FIG. 7, the above pattern is configured such that the “eyes” and “ears” of the “rabbit face” appear on the front side. In the origami of the present invention, as described above, a picture completed upon folding according to the theme shape is printed, so that the fun of origami play can be further aroused.

It is a top view which shows the expansion | deployment state before folding of an example of the origami concerning this invention. FIG. 5 is a front view and a rear view showing a folding process in the middle after performing the first folding operation on the origami of FIG. 1. It is the front view and back view which show the folding process in the middle after performing the 2nd folding operation in the origami of FIG.
