Description

[Detailed Description of the Invention] The present invention relates to an inverted toy, and more particularly to a cube inverted toy that can transform from a cube into various shapes.

There are a variety of conventional cube toys, among which the most representative one is made up of 8 unit cubes each with 3 outer and 3 inner faces painted in different colors, such as red and white. It is known that out of the 12 sides, only two nonadjacent but orthogonal sides are connected to form a large aggregate cube.

However, this toy simply turned over the set cubes one after another to obtain large cubes of different colors, so as a toy or puzzle it was simple and uninteresting. Furthermore, because the tongue-shaped film is integrally molded on the unit cube, and the joints are constructed by connecting the corners of the unit cubes with strips, the joints may break or break in a short period of time due to repeated reversing operations. There were problems such as gaps being formed due to the thickness, which made it look unsightly, and the unit cube not being properly fixed in the inverted state due to the spring back of the connecting parts, making it difficult to use.

The present invention is an attempt to eliminate the drawbacks of the conventional cubic toys of this type, and its first purpose is to create a wide variety of shapes, from the basic cube to hollow star-shaped modified octahedrons, two or more types of modified dodecahedrons, and modified hexahedrons. In addition to being able to transform into various shapes, it is also possible to enclose another cube in the cavity of a modified octahedron, or to fit another modified dodecahedron into a cube that has been transformed into a modified dodecahedron. The object of the present invention is to provide a new cubic toy that can form a planar Y-shaped cube.

The second objective of the present invention is to create a cube that is lightweight as a whole, has good durability in the inversion part, and does not create gaps between unit blocks or lose its shape due to springback at each change stage. The goal is to provide toys.

Furthermore, the third purpose of the present invention is to assemble the above-mentioned cubic toys in large quantities with synthetic resin.
The purpose of this invention is to provide a structure of unit blocks that can be assembled efficiently, firmly, and inexpensively, and a shape of adhesive tape for connecting the unit blocks.

In order to achieve the above object, the present invention connects 12 tetrahedral unit blocks, each face of which is an isosceles triangle, and uses each connection as a hinge to invert the tetrahedral unit blocks to create a cube, a deformed octahedron, and a In a cube inversion toy that can be freely transformed between deformed dodecahedrons, the tetrahedral unit block has a right-angled isosceles triangular surface and two isosceles triangles whose long sides are the short sides of the right-angled isosceles triangular surfaces, respectively. and an isosceles triangular surface whose one side is the long side of the right-angled isosceles triangular surface, and the synthetic resin hollow body has a hollow body having one triangular surface opened. and a lid piece having a planar triangular shape that matches the opening, a boss portion is formed inside the hollow body, and a pin portion is provided protruding from the inner surface of the lid piece. The lid piece is attached to the hollow body by fitting and fixing the part into the boss part, and the long sides of these right-angled isosceles triangular faces are approximately aligned between two adjacent right-angled isosceles triangular faces of each tetrahedral unit block. Attach a square piece of adhesive tape that is divided into two halves and attach it to each half, and between the two isosceles triangular faces on the corresponding back side, there is a parallel tape with an area approximately equal to the combined area of these isosceles triangular faces. The tetrahedral unit blocks are successively connected by attaching a quadrilateral adhesive tape.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 10 show an embodiment of a cube-inverted toy A according to the present invention, and this cube-inverted toy A basically consists of 12 tetrahedral unit blocks 1. As shown in FIGS. 2 and 3, each tetrahedral unit block 1 is constructed in a hollow shape from a molded synthetic resin body, each face of which forms an isosceles triangle. In other words, the tetrahedral unit block 1 has a right isosceles triangular surface 11, two isosceles triangular surfaces 12 and 12' whose long sides are the short sides of the right isosceles triangular surface 11, and a right isosceles triangular surface. 1
1 is the long side and isosceles triangular surface 12,
The two isosceles triangular surfaces 12 and 12' form an angle of approximately 55° with respect to the right-angled isosceles triangular surface 11. The isosceles triangular surface 13 is formed to be sloped from side to side by the ridge line 14, and the long and short sides of the isosceles triangular surface 13 are formed at an angle of approximately 36 degrees with respect to the right triangular surface 11.

As shown in FIG. 4, each tetrahedral unit block 1 is composed of a hollow synthetic resin main body 2 and a synthetic resin lid piece 3, and at least one triangular face of the synthetic resin main body 2, That is, in this embodiment, an opening 4 having a locking step 5 is formed on a right-angled isosceles triangular surface 11, and a boss 6 is integrally formed inside the opening 4 so as to face upward. On the other hand, the lid piece 3 is formed into a planar triangular shape that matches the opening, and a pin part 7 integrally protrudes from the lower surface of the lid piece 3, and the pin part 7 is fitted into the boss part 6 with a suitable adhesive. This provides a hollow structure with the opening 4 closed.

The 12 tetrahedral unit blocks 1 are each independent, but in the present invention, only the two adjacent faces of each of the tetrahedral unit blocks 1 are sequentially coated in an endless manner from the front and back sides with adhesive films 8 and 9. This is how they are connected. Figures 5 to 10
The figure shows the connected state. First, the adhesive films 8 and 9 are made of thin plastic film or film-type synthetic paper coated with a pressure-sensitive adhesive substance on one side, such as polyester film, polyethylene film, etc. The surface may be a single color such as red, yellow, or blue, or it may be a colored surface printed with patterns, designs, or symbols such as polka dots (not shown). The adhesive film 8 is made in the shape of a parallelogram having approximately the same area as the sum of the adjacent isosceles triangular surfaces 12 and 12' as shown in FIG. It is made into a square shape with one side having a length that roughly bisects the long side of the right-angled isosceles triangular surface 11, as shown in FIG. Each of the adhesive films 8 and 9 consists of 12 sheets.

Next, as shown in FIGS. 6 and 7, the 12 tetrahedral unit blocks 1 are made up of adjacent isosceles triangular surfaces 12 and 12' with each right-angled isosceles triangular surface 11 in contact with a plane. The lower sides are arranged to form a minute gap 10 of about 0.3 to 0.7 mm, and in this state, adjacent isosceles triangular surfaces 12 and 12'
Half parts 81 and 81' of the adhesive film 8 are glued between the spaces 12' and 12, respectively, and the half part 81 of the adhesive film 8 shown in FIG. 5b is glued to the isosceles triangular surface 12 at the starting end. , the remainder is considered a free end. The series of planar waveforms as described above are then inverted and applied to the right-angled isosceles triangular surfaces 11, 11 on the opposite side of the adhesive film 8 as shown in FIG. 5c. Adhesive film 9
The halves 91 and 91' are glued together. Half of the adhesive film 9 is adhered to the right-angled isosceles triangular surface 11 at the end, and the remaining part is left as a free end. This state is shown in FIG. 6, where a color tone or pattern is formed by the adhesive film 8 on the front side and the adhesive film 9 on the back side, and the tetrahedral unit blocks 1, 1
By adhering the front and back adhesive films 8 and 9 in the gap 10, a linear joint 15 is formed, thereby providing a thin yet durable hinge. At the same time, since the opening 4 and the surface where the lid piece 3 is fitted are covered with each half of the adhesive films 9, the appearance is improved.

Next, the waveform series of tetrahedral unit blocks described above are brought close together at one end and the other, and as shown in FIG. The adhesive film 9 on the back side was adhered to the isosceles triangular surface 12' and had a free end as shown in FIG.
The half part 91 of the tetrahedral unit block 1 is glued to the half part of the right-angled isosceles triangular surface 11 of the starting tetrahedral unit block 1, thereby connecting all the tetrahedral unit blocks 1 in an endless manner.

Note that the isosceles triangular surface 13 is a part that is not connected by the adhesive films 8 and 9, and therefore, from the overall color tone, the tetrahedral unit blocks 1 and 1 are colored in several colors such as red and yellow or white and yellow. It is preferable to make it as a colored molded body, or it is also possible to make all the tetrahedral unit blocks 1 in a single color and stick an adhesive film of the same shape on the isosceles triangular surface 13. The latter method has the disadvantage of increasing the number of steps and components.

Next, the usage conditions of the invented toy will be explained. 1st
In the basic form as shown in the figure, if one corner t where the three diagonal split planes c, c', and c'' meet is turned upward and the corner t is gently opened, the result will be as shown in Fig. 11. 2 in 12 tetrahedral unit block 1 as in
Tetrahedral unit blocks 1a, 1b, 1c,
1d, 1e, 1f, 1g, 1h, 1i, 1j, 1
k, 1l form a pair and form two isosceles triangular surfaces 13,
Since the short sides of 13 are vertically adjacent to each other, a star-shaped polyhedron B having a hexagonal hollow part 15 in the center is formed as shown in the figure.

Next, a pair of upper tetrahedral unit blocks 1a, 1b, 1e, 1f,
If 1i and 1j are sequentially reversed outward so that the isosceles triangular surfaces 13 and 13 whose short sides are in contact with each other are separated, the lower pair of tetrahedral unit blocks 1c, 1d, and 1g are obtained. , 1h, 1k, 1l, the short sides of the isosceles triangular surfaces 13, 13 are in contact with each other, and by gathering them together, a polyhedron C similar to the front Y-shape as shown in FIG. 12 is constructed. As shown in FIG. 13, the back side of this polyhedron C is a triangular pyramid part 16 in which the lower two tetrahedral unit blocks 1c, 1d, 1g, 1h, 1k, and 1l are assembled, and this triangular pyramid part 16 is one side. A deformed body D is formed, which includes three triangular sockets 17 and six hanging parts 18 that are inclined from the edges of the triangular sockets 17.

Next, from this state turned over to the back side, the two sets of tetrahedral unit blocks 1c, 1d, 1g, 1h, 1k, and 1l constituting the triangular pyramid part 16 are sequentially flipped downward and the hanging part 18 is turned over. If it is abducted until it reaches the same level as , it transforms into a front hexagonal body E with a hexagonal hollow part 15' in the center as shown in FIG.

From this state, the previous six hanging parts 18
If the three vertices 18a, 18b, and 18c are gathered perpendicularly to the center of the hexagonal hollow portion 15', a frontal triangular body F is formed as shown in FIG.
As shown in Figure 6, there is a triangular pyramid hole 19 in the center and three triangular pyramid sections 2 that use this triangular pyramid hole 19 as one side.
It becomes a nine-sided triangular body G consisting of 0.

Next, if we return from the frontal state (Fig. 15) to the state shown in Fig. 14 and bring the three sets of right triangular surfaces 11, 11 that are adjacent to each other via the hinge 21 into close contact with each other, we will obtain the state shown in Fig. 17. It has a continuous form of a large rhombic surface 22, a small rhombic surface 23a, and a small rhombic surface 23b facing in the opposite direction. The large rhombic surface 22 has two serial rhombic surfaces 23b, 23b whose long sides are in contact with each other, and the isosceles triangular surface 1, similar to the small rhombic surface 23a.
It consists of left and right rhombic surfaces 23c and 23c, which are formed by connecting the cylindrical portions 2 and 12' with hinges.
Then, if only the left and right rhombic surfaces 23c, 23c are flipped downward so that their respective bases touch each other, the right-angled isosceles triangular surface 11, as shown in FIG.
11 form a plane shape body in close contact with each other, and from this state, if they are assembled so as to eliminate the V-shaped space, it becomes an octahedron H with flat bottom and top surfaces and a deformed hexagonal plane as shown in Figure 19. Transform.

In addition, if you hold the three vertices 18a, 18b, 18c of the hanging part 18 with your fingers and lift it gently in the state shown in FIG. Block 1
If c, 1d, 1g, 1h, 1k, and 1l are rotated downward and internally rotated until their vertices gather at the center of the hexagonal hollow part 15', a triangular pyramidal hole 24 will be formed inside as shown in Fig. 20. It becomes a certain tulip-like polyhedron I. Then, if the six hanging parts 18, 18 are gathered on the center vertical line of the triangular socket 24,
As shown in FIG. 21, a modified dodecahedron J having a cubic cavity inside and a hexagonal plane is created.

Then, if this deformed dodecahedron J is opened again and one toy A' according to the present invention is made into the cubic state shown in Fig. 1 and put into the cavity, it will be deformed as shown in Fig. 22.
The result is a combination K in which a dodecahedron J has one more toy A' built into it. Also, if one of the two toys A and A' is changed to the state shown in Fig. 12, the other toy A' is transformed to the state shown in Fig. 15, and two of each are put together, the state shown in Fig. 23 is obtained. As shown in FIG. 12, both the plane and the bottom form a combination as shown in FIG.

In addition, in order to obtain the toy according to the present invention, the 24th
As shown in the figure, a triangular cavity 27 with a protruding pin 26 is formed in one mold 25, and a shallow hole 29 with a pin connected to this by a runner 28 is formed in the other mold 30. A triangular pyramid-shaped male mold 32 with a hole 31 corresponding to the pin 26 and a male mold 33 corresponding to the shallow hole 29 are provided protrudingly, and thermoplastic synthetic resin is injected into the runner 28 to perform injection molding. As a result, the main body 2 and the lid piece 3 constituting the tetrahedral unit block 1 are immediately obtained. All that is left to do is to attach the lid piece 3 to the main body 2, arrange the 12 tetrahedral unit blocks 1, and attach the required number of adhesive films 8, 9 that have been cut to predetermined dimensions in advance. Easy to manufacture with less man-hours.

According to the present invention described above, each surface forms an isosceles triangle 11, 12, 12', 13.
Using several tetrahedral unit blocks 1, only the two faces of each of the tetrahedral unit blocks 1, 1 which are in phase with each other are connected sequentially from the front and back with adhesive films 8, 9 to connect them endlessly, and the adhesive films on the front and back are 8,
Although the structure is extremely simple, because the linear joints 15, 15 of the adhesive films 8, 9 on the front and back sides form a durable hinge. , from a cube to a star-shaped polyhedron B, a Y-shaped polyhedron C, an irregular shape D, a frontal hexagonal polyhedron E, a frontal triangle F, a nine-sided triangle G, a deformed octahedron H, a hollow deformed dodecahedron I, etc. It is possible to obtain shape changes, and it is possible to provide a more advanced and complex toy than the conventional cubic toy. In addition, the tetrahedral unit blocks 1 are lightweight because they have a hollow structure made of synthetic resin, and each unit block 1 has hinges made of adhesive films 8 and 9 that also serve as colors and patterns. Even if the above-described operations for changing each shape are repeated, no gaps or cuts occur, and the shape does not collapse due to spring back, making it possible to make this kind of toy tool durable. Furthermore, in terms of manufacturing, the mold structure is simple and the number of steps is small, so it can be mass-produced at low cost.
