Description

  The present invention relates to a three-dimensional object composed of moving blocks, which is mainly used for storage devices such as puzzles, objects and packages, and also for spherical or polyhedral buildings.

JP-A-8-155135

Japanese Patent Application Laid-Open No. 8-155135 proposes a structure in which a constituent block can be moved to any position while forming a sphere.
The present invention relates to a block divided by a circle drawn around a vertex of a regular icosahedron virtually inscribed in a spherical surface, that is, 12 rotating main members, 30 auxiliary members, and 20 gap members. It is composed by combining them.
In this invention, since the configuration of the blocks is limited as described above, each block can be arbitrarily moved by moving a plurality of blocks as one set.
However, if the configuration of the block is other than the above, when the block that is unevenly fitted is moved, the locking portions formed on the periphery of the adjacent block are both convex portions, There are cases where both of them are recessed, and arbitrary rotation may not be possible.

  An object of the present invention is to make it possible to move a constituent block to any position while obtaining a degree of freedom of the constitution of the block.

In the first aspect of the present invention, in a solid in which a plurality of blocks obtained by dividing a sphere are connected to an adjacent block so as to be relatively movable, all or some of the adjacent blocks are connected via a joint member, and the joint The member constitutes a solid body constituted by a moving block with two edges fitting with the block as both convex portions or both concave portions.
The joint member needs to be disposed at a connecting portion where the convex portions or the concave portions are adjacent to each other when the block is moved, but other connecting portions are also connected via the joint. It is good.

Claims 2 and after are examples of block configurations.
The block according to claim 2 is formed by dividing an arbitrary circle passing through three or more vertices of a plane-symmetric virtual polyhedron in contact with the sphere or a circle parallel to these.
Note that any three points are selected to obtain a circle, and the number of circles to be obtained is appropriately selected, and it is not always necessary to obtain a circle for all combinations. The same applies to the third and subsequent claims.

  The above dividing method will be described with reference to FIG. When a regular dodecahedron as the plane-symmetric virtual polyhedron 2 that is inscribed in the sphere 1 is inscribed, each vertex P thereof is in contact with the sphere. The size and position of the circle represented on the spherical surface are determined by specifying three points. Therefore, a plurality of arbitrary circles R passing through three or more vertices (for example, P1 and P2 and arbitrary vertices P on the back side) are drawn on the spherical surface, and a sphere is divided along each circle to obtain a plurality of blocks.

  The block of claim 3 is an arbitrary circle passing through three or more intersections of the sphere surface with a straight line passing through the center of each ridge of the plane-symmetric virtual polyhedron in contact with the sphere and the center of the sphere, or a circle parallel to these. Divide and form.

  The above dividing method will be described with reference to FIG. A regular dodecahedron as a virtual polyhedron 2 is inscribed in the sphere 1. Let KR be the intersection of the straight line passing through the center M of each ridge of the regular dodecahedron and the center O of the sphere and the surface of the sphere. A plurality of intersections obtained on the spherical surface (for example, an intersection KR1 of a straight line passing through the middle point M1 of the ridge and the center O of the sphere and the spherical surface, an intersection KR2 of a straight spherical surface passing through the middle point M2 and the point O, and the back side A circle R passing through the same intersection point of) is drawn, and a sphere is divided along this circle to obtain a plurality of blocks.

  The block according to claim 4 is an arbitrary circle passing through three or more intersections of the sphere surface with a straight line passing through the center of each plane of the plane-symmetric virtual polyhedron inscribed in the sphere and the center of the sphere, or a circle parallel to these. Divide and form.

  The above dividing method will be described with reference to FIG. A regular dodecahedron as a virtual polyhedron 2 is inscribed in the sphere 1. Let KM be the intersection of a straight line passing through the center m of each surface of the regular dodecahedron and the center O of the sphere and the surface of the sphere 1. A plurality of circles R passing through any three or more intersections (for example, KM1, KM2, KM3 in FIG. 3) of the plurality of intersections KM obtained on the sphere are drawn, and the sphere is divided along these circles to form a plurality of blocks. Get.

The block of claim 5 is formed by dividing any combination of the circles of claims 2 to 4.
The block of claim 6 is formed by dividing the circles of claims 2 to 4 in any combination and dividing the circle by an equator line and / or a circle parallel to the equator line.
By combining a plurality of division methods as in the fifth and sixth aspects, the block can be moved in a more complicated manner.

The present invention can be applied not only to a sphere but also to a polyhedron. The regular polyhedron is divided by the method of claim 2 to 6, the dividing surface is an inclined surface toward the center of the sphere, and each block formed in the divided polyhedron is appropriately connected to an adjacent block using a joint member. By connecting so as to be relatively movable, a solid composed of moving blocks is obtained.
This aspect corresponds to a flat surface obtained by scraping off the arc surface portion of the surface of each block in the inventions of the first to sixth aspects. Further, a three-dimensional part can be attached to the surface of each block constituting the sphere to form a polyhedron, or an arbitrary three-dimensional shape.
In addition, the division surface of each block is not restricted to the said inclined surface. If the block is relatively movable, it can be a vertical plane (for example, a plane parallel to the equator plane).

  The “plane symmetry virtual polyhedron” in claims 2 to 6 is assumed to determine the position to be divided, and “polyhedron” does not exist as a component of these inventions. The shape of the virtual polyhedron is not particularly limited as long as it is plane-symmetric, and includes, for example, a regular tetrahedron, a regular hexahedron, a regular octahedron, a regular dodecahedron, a regular icosahedron, a 26-hedron, and a 32-hedron.

  The blocks are connected to each other by fitting the concave and convex portions by providing grooves on the side surfaces of the blocks to be fitted with convex portions provided on the periphery of the adjacent blocks. And at the connecting part where the rotation is hindered, a joint block in which one of the convex part or the concave part is formed on both peripheral edges of the adjacent blocks, and the concave part or both convex parts are formed on both peripheral edges is mounted. Connect adjacent blocks.

In the present invention, the block may be a thin plate or a pyramid that reaches the center of the sphere. A part of the block is removable (for example, the block is elastically deformable), or a part of the block is omitted to provide an opening, and the sphere or polyhedron is made hollow (that is, the block is thinned). ) Can also be used as a storage tool.
Each block is hollow (in the case of a sphere, the shape of each block is a hollow pyramid that tapers toward the center), and the front panel can be opened and closed so that objects can be stored in each block. Or, it can be floated in water by putting something floating in water such as a ball with air in the hollow part.
Furthermore, a small protrusion and a recess are formed in the fitting part of each block so that a click feeling (feeling of clicking) can be obtained when the block is moved and the relative position between the left and right or upper and lower blocks is correct. You can also.
In addition, the latching structure with the adjacent block shown to the following embodiment is an example, and a latching structure can be selected suitably.

The operation of the present invention will be described by taking as an example a case where the virtual polyhedron 2 having the simplest configuration is a regular tetrahedron.
In FIG. 4, in virtual tetrahedrons A, B, C, and D that are plane-symmetric virtual polyhedrons 2 inscribed in the sphere 1, the intersection points KM1 to KM4 of the spherical surface of the line connecting the center of the surface and the center of the sphere 1 are shown. Obtained (KM4 is hidden on the back and does not appear in the figure). Circles R1, 2 and B, passing through the intersection KM1 facing the two vertices A and B and the vertex A, and intersections KM2 and 2 vertices C facing the vertex B, Intersection KM3 facing two vertices D and vertex C KM4 intersecting two vertices D and A intersecting points KM4 facing two vertices D Six circles R1 to R6 passing through three points of KM1 are obtained.
A large number of blocks B are obtained by dividing the sphere 1 along the circles R1 to R6. Grooves are provided on the peripheral edges of these blocks B, and the blocks B are connected so as to be movable relative to each other via a joint member J (shown by a broken line in the drawing) that is engaged with the grooves.

Here, each block moves along the divided circles R1 to R6. For example, in FIG. 5, the block located above and below the divided circle R3 can be collectively moved along the divided circle R3, and the block located on the right side and the block located on the left side of the divided circle R4 are Each of them collectively moves along the divided circle R4. The same applies to the other divided circles. Therefore, each block can move to an arbitrary position on the sphere 1.
Since all the blocks B are connected via the joint member J, there is no possibility that the fitting portions of the blocks interfere with each other.

The configuration of FIGS. 6 to 9 is as follows.
A circle passing through the three vertices of a virtual tetrahedron A, B, C, D, which is a plane-symmetric virtual polyhedron 2 inscribed in the sphere 1, is drawn to obtain four divided circles. That is, a divided circle R1 passing through the vertex ABC, a divided circle R2 passing through the ACD, a divided circle R3 passing through the BCD, and a divided circle R4 passing through the ABD are obtained (FIGS. 6 and 7).
Next, the vertex of each of the virtual tetrahedrons A, B, C, and D passes through two points KR1 to KR6 at which the line connecting the midpoint of each ridge line and the center of the sphere 1 intersects the sphere surface. Six circles R5 to R10 are drawn, and the sphere is divided by the divided circles R1 to R10 (FIG. 8).
By connecting the blocks obtained as described above via joint members (shown by broken lines in FIG. 9), a solid body divided as shown in FIG. 9 is obtained.
Here, along each of the divided circles R1 to R10, the blocks can be rotated together for each block facing each divided circle, and each block B can be moved to an arbitrary position of the sphere 1.

FIG. 10 shows a 26-hedron. When a sphere inscribed by the 26-hedron is divided by a circle passing through three adjacent vertices of the 26-hedron, 26 blocks are obtained. The blocks obtained as described above are connected to each other through a joint member.
At this time, for example, in a circle passing through vertices A, B, C, D, E, F, G, and H, the block is bounded by a circle connecting vertices A, B, C, D, E, F, G, and H. The group can be rotated along the circle in units of Similarly, in other divided circles, blocks can be moved in units of groups with each circle as a boundary.
In addition to the above, when the sphere is divided up and down by the equator line of the sphere, it is divided into 34 blocks, and when joint members are arranged in the equator part and the upper and lower blocks are connected, a group with the equator as a boundary is used as a unit. It can be rotated along the equator.
Further, the blocks may be divided by dividing them into a plurality of circles parallel to the equator line or meridian, and connecting the opposing blocks by disposing a joint member in each circular portion.

Further, since the 26-hedron shown in FIG. 10 is plane-symmetric, the 26-hedron itself can be a solid composed of moving blocks.
That is, the first divided surface including the vertices A, B, C, D, E, F, G, and H, the second divided surface parallel to the first divided surface including the vertices I, J, and K, the vertex A When the 26-hedron is divided by a third divided surface perpendicular to the first divided surface including D and a fourth divided surface parallel to the third divided surface including the vertices H and E, there are 26 26-hedrons. Divided into blocks. And adjacent blocks are connected via a joint member so that each block can be rotated and moved by the group unit which used the division surface as a boundary along the said division surface.
The side surface shape of each block is an inclined surface toward the center of the 26-hedron, and is a quadrangular pyramid or a triangular pyramid.
Both the concave and convex portions are formed in a circle centered on the center point of each dividing plane, thereby enabling movement in group units with the dividing plane as a boundary.
In the present invention, “can move to an arbitrary position” means that the block can be moved to a position where the other block is located before the movement, and does not mean only when the other block is replaced. .

The solid composed of the moving blocks of the present invention can be used as a puzzle by representing a picture or pattern on the surface, or can be used as an object whose picture can be changed. Moreover, it can also be used as a thing case by providing an opening part in a part of block. Furthermore, a three-dimensional shaped object can be added to the surface of each block, and it can also be used for buildings. If a building is comprised by this invention, the combination and pattern of the color of the outer wall of a building can be changed suitably.
The block may be flat or thick, reaching the center of the solid, and is selected according to the purpose of use.

According to the present invention, the joint block is interposed whenever necessary to connect the blocks. Therefore, when all the blocks are directly connected, it is possible to avoid a situation where adjacent blocks become convex or concave portions and cannot be moved when the blocks are moved.
Depending on the configuration of the block, it is possible to move freely without using joint members, but when the block configuration is complex, complicated verification of which peripheral edge of each block is convex and which peripheral edge is concave Work is required. However, in the present invention, if joints are interposed in the connecting portions of all the blocks, interference does not occur, and a solid that can be moved freely and reliably can be obtained without performing verification work.

The side surface of each block is an inclined surface toward the center of the sphere, and is connected so as to be movable for each adjacent block. In the connection structure, a groove is provided on the side walls of both blocks, and the connection is made by a joint body (shown by a broken line in FIG. 13) that fits in the groove.
In the above-described division example, a joint can be inserted only at the part of the dividing line shown in FIG. 12, and the blocks can be freely moved even if the blocks are directly fitted with each other by males and females.

In this embodiment, the divided circles R5 to R10 divide the sphere into hemispheres, so that each block can move freely along the divided circles R5 to R10. That is, the blocks B2-11, B2-3, B2-6, B2-9, B2-12, B2-1, and B1-2 other blocks along the divided circle R9 are a set of blocks behind them. Rotate, and the blocks that are confronted by each divided circle also rotate along one other divided circle.
Therefore, for example, the block B2-11 can be rotated 180 degrees along the divided circle R9 and moved to a point-symmetrical position, and then rotated along the divided circle R5 and moved to the position B1-1 in the figure. . And each part block can be moved to arbitrary positions in the same way.

Here, a concave portion is formed on the peripheral edge of the triangular block B, and a convex portion is formed on the peripheral edge of the tree-like block J to be connected. In this embodiment, the leaf-like block J of the tree constitutes a joint member.

In the sphere configured in this way, for example, five triangular blocks centering on the point A and five leaf-like blocks of a tree can form a group and rotate along the divided circle R1. Similarly, since other blocks can be rotated along other divided circles, each block can freely move to any one of the spheres.
And in the movement, the uneven | corrugated fitting part of each block does not interfere.

  FIG. 36 shows a division based on a regular dodecahedron inscribed in a sphere (it can also be obtained from a regular icosahedron). The divided circle R1 is a circle that passes through vertices A and B at both ends of one side H1 of the pentagon G1 constituting the regular dodecahedron and a midpoint C of the pentagon G2 sharing the side H2 adjacent to the side H1 (FIG. 37). In the same manner, when a divided circle is obtained based on a pentagon that forms a regular dodecahedron, a dividing line shown in FIG. 38 is obtained on the sphere. When the sphere is divided by these dividing lines, two kinds of triangular blocks B1 and B2 to be mirrored are obtained. Concave portions are formed below the peripheral edges of these blocks B1 and B2, and are connected by a joint block J to form a sphere.

The sphere configured as described above can rotate along the divided circles by forming blocks inside the divided circles as a group along each divided circle. Similarly, since other blocks can be rotated along other divided circles, each block can freely move to any one of the spheres.
And in the movement, the uneven | corrugated fitting part of each block does not interfere.

FIG. 39 is divided based on a regular dodecahedron circumscribing the sphere. The divided circle R1 is a midpoint of one side H1 of the pentagon G1 constituting the regular dodecahedron, a midpoint of the side H2 facing the side H1, and a midpoint of H3 facing the side H2 of the pentagon G2 sharing the side H2. It is a circle that passes through. In the same manner, when a divided circle is obtained based on a pentagon that forms a regular dodecahedron, a dividing line shown in FIG. 40 is obtained on the sphere.
The divided circle r1 is a circle that passes through the midpoint between two adjacent sides H1 and H4 of the pentagon G1, and corresponds to the equator of the sphere (FIG. 41).
When the sphere is divided by these dividing lines, a triangular block B, a vertically long triangular block C, and a pentagonal block D having the same size are obtained. Here, the blocks B that are in contact with each other via the equator line are both formed with a recess at the joint and connected via the joint block J, and the other blocks are each provided with a recess or a protrusion on the adjacent edge. A sphere is formed by directly fitting and connecting.

The sphere configured as described above can rotate along the divided circles by forming blocks inside the divided circles as a group along each divided circle. Similarly, since other blocks can be rotated along other divided circles, each block can freely move to any one of the spheres.
And since it connected via the joint block in the equator part, the uneven | corrugated fitting part of each block does not interfere in the case of a movement. In addition, you may connect all the blocks through a joint block.

FIG. 42 shows a block obtained by further dividing the block obtained by the dividing line shown in FIG. 32 in the following manner.
First, the parallel dividing lines R1a and R1b, R2a and R2b, R3a and R4b, and R5a and R5b between the equator lines in FIG. 32 are divided by circles RM1, RM2, RM3, RM4, and RM5 (FIG. 43). Next, the block is divided by a circle Rm connecting the centers of the sides of the pentagonal block 61 in FIG. 32 to obtain a divided block (FIG. 44).
Of each of the divided blocks, a groove is formed on the entire periphery of the block obtained by dividing the pentagonal block, and a convex portion is provided at an edge in contact with the pentagonal block sandwiched between parallel dividing lines. Connect. Further, the blocks sandwiched between the parallel dividing lines are connected by appropriately forming grooves or convex portions on the periphery.
In this embodiment, the block sandwiched between the parallel dividing lines serves as a joint block.
In addition, the connection between the blocks sandwiched by the parallel dividing lines can also be performed by a joint block separately prepared.

FIG. 45 is obtained by dividing both the dividing line of FIG. 36 and the dividing line of FIG. 42 to obtain 1080 divided blocks, which are provided with grooves on the entire circumference and connected by joint blocks.
By using a joint block, even in such a complicated divided block, the block can be moved to an arbitrary position without the coupling part interfering with each other.

According to this invention, the block which comprises a solid can be moved to the arbitrary positions on a solid by using a joint block. In particular, even when the number of blocks is large, it is not necessary to verify the presence or absence of interference between the concave and convex fitting portions.
Therefore, by appropriately decorating the surface of the block, it can be used as an object, a building or the like whose puzzle or pattern changes.
