  Hereinafter, embodiments of the present invention will be described more specifically with reference to the drawings.

  FIG. 1 is an explanatory view of a polyhedron showing the basic structure of a hollow structure. As shown in FIG. 1, the hollow sphere according to the present embodiment is basically composed of a polyhedron in which a pentagonal region P and a triangular region T are combined. Twelve pentagonal regions P, triangular regions T Is composed of 20 pieces.

  On the other hand, as a regular polyhedron, a regular tetrahedron having a triangular pyramid shape composed of four regular triangles, a regular hexahedron having a cubic shape composed of six squares, and a regular hexahedron composed of eight regular triangles, each having a pyramid shape vertically stacked. There are an octahedron, a regular dodecahedron composed of 12 regular pentagons, and a regular icosahedron composed of 20 regular triangles.

  Among the five regular polyhedrons, the one closest to the sphere is the regular dodecahedron having the largest number of vertices, ie, twenty. When a spherical body is constituted by a polyhedron, it is reasonable to use this regular dodecahedron as a basis. At this time, since the 20 vertices are formed by three regular pentagons, it has been found that when this vertex portion is replaced with a regular triangular surface, the polyhedron is more nearly spherical.

  That is, when three regular pentagons are connected, a sheet in which a regular pentagonal region and a regular triangular region are formed may be formed, and as such a sheet, a regular pentagonal region can be formed with a single sheet, In addition, it can be seen that an equilateral triangle region may be formed when three sheets are connected.

  In addition, when the three sheets are connected, it is even better if the connecting portion has a decorative property. From such a viewpoint, the sheet 10 shown in FIG. 2 was created.

  FIG. 2 is an explanatory view of the sheet 10 constituting the hollow sphere according to the present embodiment. As illustrated, the sheet 10 includes a regular pentagonal base portion 1 and sides 1a, 1b, 1c of the base portion 1. , 1d, and 1e, respectively.

As shown in the drawing, the hollow sphere according to the present embodiment is composed of a polyhedron composed of 12 substantially pentagonal regions and 20 substantially triangular regions. The substantially pentagonal region is formed by the base portion 1 of each sheet 10, and the substantially triangular region is formed by connecting each one deformed portion 2 of the three sheets 10.

  And the decoration part 4 which serves as the connection part of each sheet | seat 10 is formed in a substantially triangular area | region. The decorative portion 4 according to the present embodiment has an appearance like a flower, and is a novel and beautiful spherical body that can be used as an object or a figurine.

  Moreover, since the sheet | seat 10 is formed from the material which has a fixed elastic force using resin etc., for example, when the three deformed parts 2 are combined, it will become the three-dimensional decoration part 4, and an appearance will improve more. In addition, the sheet | seat 10 which concerns on this embodiment uses the reinforced Japanese paper which pinched PET (Polyethylene Terephthalate) between Japanese paper and Japanese paper as the material.

  As shown in FIG. 2, the deformed portion 2 of the seat 10 according to the present embodiment includes a connecting portion 21 that is connected to the sides 1 a, 1 b, 1 c, 1 d, and 1 e of the base portion 1, and a bent portion from the connecting portion 21. The connecting claw portions 22 are extended to form a decorative portion 4 (see FIGS. 3A and 3B).

That is, as shown in FIG. 2, the engaging portion 40 is formed in a cove at the boundary between the connecting portion 21 and the connecting claw portion 22 of the deformed portion 2. Then, the end 40a of the engagement portion 40, by positioning each vertex of a virtual regular pentagonal P1 of the base portion 1 of the regular pentagon is inscribed, when constructed hollow spheres as shown in FIG. 3A, B The end 40a of the engaging portion 40 is positioned at the center of the decorative portion 4. And since the connection nail | claw part 22 which concerns on this embodiment is formed in the petal shape, the decoration part 4 looks like a flower which uses the three connection nail | claw parts 22 as a petal.

  Each connecting portion 21 is formed with a first protruding portion 41 and a second protruding portion 42 that overlap with the other deformed portion 2 in the decorative portion 4. Here, the first projecting portion 41 is projected in a mountain shape on the side where the inlet-like engagement portion 40 is formed, and the second projecting portion 42 is formed on the opposite side of the first projecting portion 41. Yes.

  As shown in FIGS. 3A and 3B, the hollow spherical body configured using such a sheet 10 also serves as a connecting portion between the sheets 10 on the surface, and a beautiful decorative portion 4 as if it is a flower is formed. Therefore, it can be used as a nice-looking object or figurine. In addition, the connecting claw portion 22 according to the present embodiment is a petal inspired by cherry blossoms, and the sheet 10 is formed of Japanese paper. Therefore, as shown in FIGS. Can be obtained (see FIG. 8).

  By the way, in this embodiment, twelve sheets 10 are connected to each other to construct a hollow sphere, but here, using three sheets 10, a hollow is shown while showing an example of a connecting procedure between sheets. The decorative portion 4 that also serves as a spherical connecting portion will be described with reference to FIGS. In addition, the decoration part 4 in FIGS. 4-6 is comprised by engaging each connection nail | claw part 22 in order of the 1st sheet | seat 10A, the 2nd sheet | seat 10B, and the 3rd sheet | seat 10C. In addition, in order to facilitate understanding, each part of the first sheet 10 </ b> A, the second sheet 10 </ b> B, and the third sheet 10 </ b> C, such as each deformed part 2 and the connecting claw part 22 constituting each deformed part 2, is also described. In addition, according to the first sheet 10A, the second sheet 10B, and the third sheet 10C, A, B, and C are added to the reference numerals for distinction.

  First, as shown in FIG. 4, the connection claw portion 22B of the second sheet 10B positioned at the middle position is engaged with the connection claw portion 22A of the first sheet 10A positioned at the highest position among the three sheets, The connecting claw portion 22C of the third sheet 10C positioned at the lowest position from below the connecting claw portion 22B of the second sheet 10B is engaged. At this time, the deformed portion 2C including the connecting claw portion 22C of the third sheet 10C is positioned below the deformed portion 2B of the second sheet 10B, but is different from the deformed portion 2A of the first sheet 10A. Overlaid on top of it. In this way, one decorative portion 4 is shaped like a flower, but in this state, the first sheet 10A, the second sheet 10B, and the third sheet 10C are still two-dimensionally spread in the plane direction. The state remains.

  Next, the other connecting claws 22 are connected to each other so that the other decorative portion 4 is formed. The other connecting portion between the first sheet 10A and the second sheet 10B is taken as an example. Then, as shown in FIG. 5, the deformed portion 2A of the first sheet 10A located at the upper position is replaced so as to be positioned below the second sheet 10B. Similarly, when another connecting portion between the second sheet 10B and the third sheet 10C is taken as an example, the deformed portion 2B of the second sheet 10B, which has been positioned at the upper position, is replaced with the third sheet 10C. When the second sheet 10C and the first sheet 10A are taken as an example, the deformed part 2C of the third sheet 10C, which is located at the upper position, is replaced with the lower sheet so as to be positioned below. It replaces so that it may be located under 10A of 1st sheets.

  As shown in FIG. 6, when another connecting portion between the first sheet 10 </ b> A and the second sheet 10 </ b> B is taken as an example, the connecting claw portion 22 </ b> A of the deformed portion 2 </ b> A of the first sheet 10 </ b> A is used. The engaging portion 40 (see FIG. 2) is engaged with the engaging portion 40 of the connecting claw portion 22B of the second sheet 10B. Similarly, if another connecting portion between the second sheet 10B and the third sheet 10C is taken as an example, the engaging portion of the connecting claw portion 22B of the deformed portion 2B of the second sheet 10B. 40 (see FIG. 2) and the engaging portion 40 of the connecting claw portion 22C of the third sheet 10C are engaged, and another connecting portion between the third sheet 10C and the first sheet 10A is taken as an example. If this is the case, the engaging portion 40 (see FIG. 2) of the connecting claw portion 22C of the deformed portion 2C of the third sheet 10C and the engaging portion 40 of the connecting claw portion 22A of the first sheet 10A are connected. Engage.

  Thus, when the three sheets 10 composed of the first sheet 10A, the second sheet 10B, and the third sheet 10C are connected to each other, the connecting claw portion 22 formed in the shape of a petal has a hook shape. By being combined, the decorative part 4 simulating a flower is formed. In addition, since the decorative portion 4 is made of a material having elasticity, the connecting claw portions 22 that are superposed in a triple state are in tension, and the decorative portion has a three-dimensional appearance. 4

  Similarly, when all the 12 sheets 10 are used and the sheets 10 are connected to each other, as shown in FIGS. 3A and 3B, a regular pentagonal base portion formed on each sheet 10 is used. A hollow spherical body made of a polyhedron in which 12 substantially pentagonal regions made of 1 and 20 substantially triangular regions formed by connecting deformed portions 2 attached to each side of the base portion 1 are combined. Constructed (see FIG. 1). And since the decoration part 4 which serves as the connection part of each sheet | seat 10 is formed in a substantially triangular area | region, the beauty | look as a hollow spherical body can be improved remarkably.

  In addition, since the first projecting portion 41 and the second projecting portion 42 are formed in the connecting portion 21 of the sheet 10 as described above, the gap between the adjacent sheets 10 is overlapped with each other. Can be prevented, and the strength of the hollow sphere can be increased.

  By the way, this hollow spherical body can be suitably used as a lamp shade as shown in FIGS. Although this hollow spherical body is constructed by connecting twelve sheets 10, the surface has almost no gap and has a substantially spherical surface. Therefore, the sheet 10 is formed of a light-transmitting or semi-light-transmitting material so as to transmit the light of the lamp 6 disposed therein. 7 and 8, reference numeral 60 indicates an electric code of the lamp 6.

  Such a lamp shade has a first protrusion 41 and a second protrusion 42 formed on the connecting portion 21 of the sheet 10 that constitutes the shade, so that the adjacent sheets 10 are superposed with each other as described above. As shown in FIG. 8, when the light is turned on, shading due to superimposition appears in the decorative portion 4 as shown in FIG. Therefore, it can be seen that, when the lamp is lit, the effect of increasing the aesthetics is obtained, and the hollow sphere is suitable as the lamp shade.

  In addition, the lamp shade is configured by connecting twelve sheets 10, but almost no gaps are formed on the surface thereof. Therefore, it is possible to prevent as much as possible the possibility of insects and the like entering the shade.

  9A (a) to 9B (g) and FIG. 10 are hollow spheres (lamp shades) according to other embodiments. Moreover, what was shown in FIG. 11 is explanatory drawing of the sheet | seat which comprises the hollow spherical body (lamp shade) which concerns on the said other embodiment.

  The hollow structure and the lamp shade according to the present embodiment are the same as the hollow spherical body and the lamp shade according to the above-described embodiment, except that only the design of the decorative portion 4 is changed. is there. Therefore, in the figure, the same components as those of the previous embodiment are denoted by the same reference numerals, and the detailed description thereof is omitted.

  In this embodiment, the connection claw part 22 of the sheet | seat 10 which comprises the decoration part 4 is formed in the simpler circular shape instead of a petal shape. Therefore, it is not particularly Japanese style, and it becomes a hollow structure or lamp shade that matches both Western and Japanese style rooms.

  Although the present invention has been described above through the embodiments, the specific configuration may be changed as appropriate without departing from the spirit of the present invention. For example, the shape of the connecting claw portion 22 that substantially defines the design of the decorative portion 4 can be changed to a desired shape as appropriate.

  Moreover, when using as a material of the sheet | seat 10 as an object or a figurine, the color, a pattern, a material, etc. are not specifically limited. Any material having moderate elasticity that can be assembled by a human hand may be used. In addition, when used as a lamp shade, anything that transmits light may be used.
