Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to manufacturing a sphere by forming each surface of a developed view of a polyhedron to form a part of a spherical surface, assembling the developed view into a spherical shape, and bonding the abutting sides. It is about the method.

Conventionally, in the method of manufacturing a sphere, the whole sphere or
Each hemisphere was molded in one piece. For this reason, there are restrictions on the materials that make up the sphere, and when printing on the surface, advanced printing technology is required, and printed divided paper is attached to the surface of the sphere, which increases the height. There was a problem with poor transportation efficiency.

However, in this invention, each surface of the polyhedron's developed view is formed to overhang so as to form a part of a spherical surface, the developed view is assembled into a spherical shape, and the abutting sides are glued to produce a sphere. ,
Paper or soft synthetic resin can also be used as the material for the sphere. Further, even when printing is to be performed on the surface, the arc bleeding formed on each side of the developed view is extremely close to a flat surface, so printing can be easily performed. Furthermore, it can be packaged and transported as a flat plate before assembly, and the volume for transport can be reduced, which solves the above-mentioned conventional problems.

Embodiments of the present invention will be described based on the drawings.

Arrange the same shaped horn shapes 1 horizontally on 8 sides via folds, touch the upper and lower sides of odd numbered squares 1 from the left, and fold the same shaped square shapes 2 to form l'. Intermediate-C are connected, and on the third embossed shape 1 from the left in the horizontal direction, a square 3 is placed in contact with the top and bottom sides of the square 2 through the crease,
On the upper and lower sides of the even-numbered square ``1'' from the left, an equilateral triangle 4 whose upper and lower sides have the same length is in contact with C through the fold, and has an iFh shape '1.2.3, a regular triangle 4. Each abutment of the triangle 4) forms a glue margin 5 on u, and a developed view of the 26-hedron 6
form.

When each surface in the development diagram 1 is assembled as a polyhedron, a part of the spherical surface is ejected into an arc 1ffj.
7 is provided, and the arc surface 7 is a3 at the fold 8 of each surface and JJ'
Turn the curved part 9. Assemble the developed view 1 in the above into a spherical shape - C, glue margin 5 near the joint shown in the developed view 6
Glue and fix to N.

If we apply the h method of this explanation, a spherical surface is formed by the arc surfaces 7 formed on each surface, and a sphere 1 and 10 can be easily obtained as a whole.

Next, FIG. 4 is a developed view 11 of another embodiment in which the polyhedron is an icosahedron, in which equilateral triangles 12 of the same shape are connected.

A margin 13 is provided on each contact side of the equilateral triangle 12, and each face is made into a polyhedron.
A part of the surface is formed into a curved shape to form an arcuate surface. A sphere can be obtained by assembling the expanded view 11 in the same manner as in the embodiment.

Further, FIG. 5 is a developed view 16C in which the polyhedron is turned into a tetrahedron consisting of four planes 14 and one end of an arc 15 formed on each surface is connected.

In this embodiment, a sphere can be obtained by assembling the developed view 16 by adhesively fixing the folded portions 17 to each other.

The sphere obtained by this example has the effect of having fewer errors.

Further, FIG. 7 is a developed view 18 of another embodiment in which the polyhedron is a 120-sided polyhedron, and a trapezoid 191) having a length of 120 mm is defined as the base of the trapezoid 19a. The upper sides of the trapezoid 19 () are brought into contact with each other, and the planes 20 of the trapezoids 19c, 19d, and 19e, each having the same quality as the base jυ, are connected in sequence at intervals of 120 degrees with the upper side of the trapezoid 19a as the center. 1, a glue margin 21 is provided on each abutting side of the trapezoid, and an arcuate surface 22 is provided on each trapezoid surface. If you assemble , you will get 1q of spheres in the same way.

Figure 8 is a developed view 24 of a polyhedron made by connecting 12 planes consisting of -(-15 isosceles triangles 22) and using an IC60-hedron.
It is a hub.

Each face of the isosceles triangle 22 has a protruding shape.
It is.

A sphere can be obtained by assembling C by gluing the adhesive margins 23 together.

Furthermore, 'A9 figure is a polyhedron 'C10 regular hexagons 2b
I
Developed view of C-C. Each abutting side is provided with a glue margin 27, and each face of the regular hexagon 25 and the regular pentagon is formed into an arc to form an arc surface. A sphere can be obtained by assembling the glue margins 27 by adhering them to each other.

In the above embodiments, the polyhedrons are one ζ tetrahedron, icosahedron,
Although a 26-hedron, a 120-hedron, a 60-hedron, or a 32-hedron are used, the window is not limited to these, and can be windowed as appropriate. Paper was used as the material, but
The material is not limited to this, and a soft synthetic resin or the like may be used as appropriate.

According to the invention of Chiko 11J, each surface of a developed view of a polyhedron is formed to form a part of a spherical surface, the developed view is assembled into a spherical shape, and the abutting sides are glued to produce a sphere. Therefore, it is possible to use paper, soft synthetic resin, etc. for the material that makes up the sphere (it is easy to print on the surface, and it can be transported as a flat plate before assembly. 1
1QC monkey C has the effect of having good transport efficiency. Furthermore, if you use a developed view whose overall shape is approximately rectangular, you can use the moon o' without any trouble.
