Origami

Abstract

To provide a large triangular sheet, the folding puzzle, consisting of 15 small equilateral triangles to be folded into a pentagonal pyramid of the same color.SOLUTION: Origami, the printed sheet, is characterized in that a triangular sheet consisting of 15 triangles is folded at sides to form petals of three-dimensional pentagonal pyramid shape of the front / back same color, at ten positions. At cherry blossom festival and other events, a workshop to create original puzzles can be held, where the sheet is blank paper excluding ten pink parts on the front and back that will become the petals, so that participants may stick stickers thereto, draw original pictures and symbols, or put colors thereon, further participants fold the sheet, use adhesive tape to hold the pentagonal pyramid in place, and then decorate the finished cherry blossom petals or take them home, thus livening up the event. When the ten parts are printed in blue, flower petals of Tweedia are created, and when printed in purple, it can express a bellflower.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to origami of artificial flowers and petals. [Background technology]

[0002] Traditional cherry blossom petal origami involves folding a square piece of paper and cutting it with scissors into the shape of five petals. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-000000 Summary of the Invention [Problem to be solved by the invention]

[0004] The problem to be solved by the present invention is to provide a large triangular sheet made up of 15 small equilateral triangles, which can be folded into a pentagonal pyramid as a folding puzzle. [Means for solving the problem]

[0005] This invention is an origami paper that can be folded along the edges of a triangular sheet made up of 15 pieces to create petals of a three-dimensional pentagonal pyramid shape on both sides in 10 places of the same color. The present invention provides a triangular sheet made up of 15 equilateral triangular sections of the same size, each of which has a folding line between adjacent equilateral triangular sections, 10 faces of which are colored, and which can be used to form a pentagonal pyramid shape. Here, an equilateral triangle is sufficient as long as it can form a pentagonal pyramid shape, and does not necessarily have to be an exact equilateral triangle. The same dimensions mean that they are the same size enough to be able to be stacked, but they do not need to be exactly the same size. [Effects of the Invention]

[0006] With the origami of this invention, workshops can be held at events such as cherry blossom festivals, where participants can create original puzzles with the 10 pink areas on the front and back that will become the petals left blank, or with stickers or original pictures, symbols, and colors. The completed cherry blossom petals can then be folded and held in place with adhesive tape, allowing them to be displayed or taken home, adding excitement to the event. The finished products can also be sold as artificial flowers. If you use blue, you can express the petals of a blue star, and if you use purple, you can express the petals of a bellflower.

Claims

1. A triangular sheet made up of 15 equilateral triangular portions of the same size, each of which has a folding line between adjacent equilateral triangular portions, at least one side of at least five of the equilateral triangular portions being colored, and the 15 equilateral triangular portions can form a pentagonal pyramid shape.

2. A triangular sheet made up of 15 equilateral triangles of the same size, each of which has a folding line between adjacent equilateral triangles, at least one side of at least three of which is colored, and the 15 equilateral triangles can be used to form a triangular pyramid or a square pyramid.
