Abstract

PURPOSE:To obtain a profitable effect such as to comprehend the meaning and role of a line set and to discover the way of folding paper different from the conventional way concerning how to fold paper as well by using the art of folding paper using a partitioned connection method for child education, for example. CONSTITUTION:On the front and rear sides of square paper 1, a front line set and a rear line set are printed to show projecting folding lines, for example, when respectively completely folding the both sides. Further, area patterns to be formed by these paired line sets are colored. After educating how to folding paper as the first step, the colored paper with the printed line sets to use the partitioned connection method is distributed to children as the second step. The child, who folded the paper to a cicada, for example, in the education of the first step, can estimate the completely folded form of cicada according to the line sets and coloring. Since the paper is folded by using these line sets and coloring, the profitable effect can be obtained for the learning, etc., of children so as to comprehend the meaning and role of the line set and to discov er the way of folding paper different from the conventional way, as well.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to origami using the piecewise connection method, which is used, for example, in children's education.

[Conventional technology]

Origami is being used to educate children.

Such origami is classified into so-called traditional origami and creative origami, both of which are folded using square paper colored in white or a single color. When folding origami, especially in traditional origami, the paper is folded up one after the other according to a predetermined folding method.

[Problem to be solved by the invention]

The inventor of the present application previously announced the categorical subjunctive method as a form of understanding "things."

Literature: “About the creative teaching method using the piecemeal conjunction method” Proceedings of the Japanese Society of Industrial Technology Education 1986 ``About the piecemeal conjunction method” (1988) “About the piecemeal conjunction method” (1989) Therefore, when considering origami from these studies, , the fold line combination rule consists of a set of mountain fold lines (or a set of valley fold lines) appearing on the front and back sides of the paper.

In other words, when origami that has been folded up into an arbitrary shape J is fully opened to the original paper, the folds necessary for folding up the origami will appear neatly separated into the front and back sides of the paper.

The set of mountain fold lines (or the set of valley fold lines) that appear on the front and back sides of the paper are called the front line set and the back line set, respectively.
Since these are pairs, we put them together as a pair (
(ts) called a line set. In origami, this set of paired lines becomes a connection rule, and the folding process into a ``shape'' progresses one section at a time.

This application was filed in view of these points.

[Means to solve the problem]

The first means according to the invention is that the paper when folded up (
1) The front and back of the above-mentioned paper so that the set of lines indicating the mountain fold or valley fold lines (solid lines) on the front side and the line set indicating the mountain fold or valley fold lines (broken lines) on the back side can be distinguished from each other. Origami is an origami paper that uses the segmental connection method and is characterized by printing on the back side.

The second method is to combine the mountain fold or valley fold line (solid line) on the front side of the paper (1) and the line set indicating the cutting line (chain line) and the mountain fold or valley fold on the back side when folded up. This origami is an origami paper using a segmented connection method, characterized in that lines (broken lines) and line sets indicating cut lines (dashed lines) are printed on the front and/or back sides of the paper so that they can be distinguished from each other.

A third means is origami using the section connection method described in the first or second means, characterized in that only a part of the line set on the front and/or back side of the paper is printed.

A fourth means is characterized in that the area pattern formed by the line set on the front and/or back side of the paper is colored (each indicated by a color name). This is origami using the piecewise subjunctive method.

[Effect]

According to this, by using origami using this method of segmentation and connection, for example, in the education of children, the meaning and function of line sets will be naturally understood, and new folding methods will be discovered. etc. can have beneficial effects.

〔Example〕. Figure 1 shows a case where it is applied to the traditional origami "cicada", for example, and a set of front lines (solid lines) showing, for example, mountain fold lines when folded up on the front and back sides of a square paper (1). and a set of back lines (dashed lines) are printed. Further, the area pattern formed by the set of these paired lines is colored, for example, as indicated by the color name in the figure.

Therefore, when origami using this method of segmentation and connection is used for children's education, it is done as follows.

That is, in the first step, a square blank sheet of paper is used to fold it into an arbitrary "shape" according to the conventional origami folding method, for example. The folded paper is fully unfolded and, for example, mountain fold lines formed on the front and back sides of the folded paper are traced with a pencil to form a front line set and a back line set. Furthermore, the set of lines formed on the back side is transferred onto the front side using, for example, a red pencil to form a set of paired lines. Then, the area pattern formed by the set of paired lines is colored in consideration of the "shape" when folded up.

After the first stage of education has been carried out, the second stage is to distribute origami to the children using the section connection method, in which the above-mentioned line sets are printed and colored.

Even if a person who has not received the above-mentioned education looks at origami using this method of segmentation and connection, he or she will not be able to imagine a folded-up cicada (see Figure 2) from this set of lines and coloring. It is difficult.

However, after the first stage of education, for example, it is not difficult for children who have folded cicadas, and they will be able to guess the folded cicada from these line sets and coloring.

By folding origami using these line sets and coloring, children naturally understand the meaning and function of line sets, and discover new ways of folding. It is something that can have beneficial effects.

Furthermore, when children who have received this education are given origami paper that uses different categorical connections of "shapes" without instructing them how to fold it, the children will infer the "shape" only from the set of lines and coloring. By researching folding methods and folding, for example, a parallel folding method in which all the lines are made with the necessary creases and folded at the same time, we have discovered new folding methods. It can have a beneficial effect on learning.

Figures 3 and 4 show front line sets and back line sets for shapes other than 'cicada', and Figure 3A shows 'boat'.
, Figure B shows ``Duck'', Figure C shows ``Orizuru'', Figure 4 A shows ``Koi'', Figure B shows ``Yakko-san'', and Figure C shows ``Paper Balloon''.

By the way, FIG. 5A shows a so-called "headpiece" pair line set (area pattern). In this example, new educational effects can be obtained by using origami with only a part of the line sets printed, as shown in the same figure.

Further, FIG. C shows a set of paired lines when performing so-called linked folding between the above-mentioned "headpiece" and, for example, "thigh", and the dashed-dotted line in the figure shows a cutting line for making incisions. Here, although such linked folding is not easy to fold in traditional origami, the above-mentioned parallel folding method makes folding relatively easy.

And in this case, a new concept of cutting lines was introduced into origami. Note that the cutting line here may be either a line indicating the cutting position or a line that has already been cut.

Therefore, Figures 6 and 7 are a set of front lines, a set of back lines, and a set of paired lines (area pattern) of origami including this cutting line (dotted chain line).
Figure 6A shows "goldfish", Figure B shows "tortoise", Figure 7A shows "water lily", Figure B shows "swallow", and Figure C shows "Tokyo Tower". It shows.

Educational contents using origami using the above-mentioned piecewise connection method include, for example, an explanation of the basics of group theory using domain patterns, an explanation of the essence of parallel computers, an explanation of fault folding, and an explanation of the difference between Hume and Kant's subjectivity regarding the establishment of natural science. Possible explanations include.

Furthermore, in the above-mentioned "cicada" embodiment, the range of the area pattern that is not colored is the part that cannot be seen from the outside when folded up. Therefore, it is possible to print product photos and price lists in these areas to create promotional catalogs and flyers. According to this, the catalogs, etc. can be used for children's learning, etc., and the catalogs, etc. folded up into "shapes" are likely to be kept in the home for a long time, which can increase the advertising effect. be.

〔Effect of the invention〕

According to this invention, by using origami using this segmental and connecting method, for example, in the education of children, the meaning of line sets and their functions will be naturally understood, and new folding methods will be discovered. It is now possible to bring about beneficial effects such as:
