Description

A TOY BLOCK UNIT HAVING 50 FACES AND A TOY BLOCK SET CONSISTED OF TOY BLOCKS MADE THEREFROM}

The present invention relates to a block and a block group having 50 faces, and more particularly, to a block and a block group having 50 faces that can bring about an effect of inducing an intelligence improvement.

Existing intermediate block is composed of several modules, and the shape of the module is rectangular, spherical, and plate-shaped. Among them, the old modules are the safest, but when stacked, the contacts between the old modules are easily “point contacts”, and thus are easily vibrated. The stacked state can be easily released due to the user's touch or the like. Therefore, improving the stability of the spherical block has become a major task to be improved.

The contact between the spherical module and the plane is also "point contact", and it can be stacked only on the chassis with the positioning hole, and without the chassis, the stacking is difficult to proceed. What you can do is a task that needs to be improved.

The spherical blocks cannot be inclined independently because they cannot be inclined when building a triangular pyramid, and they must be supported by other blocks, and they are difficult to find even in the case of an error in the angle. Improving the fixing effect also became a challenge.

In addition, when removing the old block, it is easy to get out of the hand, and the improvement of the anti-slip effect also has to be improved.

Next, the included angle of the block will be described. In the existing invention, the connection angle between the block modules is 90 degrees or 45 degrees, for example, in Fig. 1 of the prior art Taiwan No. TW398313 (or US Patent No. US 6,220,919), 18 differently shaped blocks are presented. Each block consists of 3 ~ 6 spherical modules, and the included angle between spherical modules is 90 degrees. On the other hand, Figure 16 shows a three-layered five-sided pyramid stacked in four blocks, Figure 17 shows a four-layered five-sided pyramid stacked in seven blocks, Figures 18 and 19 shows a five-layered five-sided pyramid stacked in 12 blocks. Among them, only the five-sided pyramids (four sides and one base) are disclosed, but there are no triangular pyramids (three sides and one base). It became.

In the prior art Taiwan No. 2 TW M362714 (US Publication No. US 2010/0237561), Figure 7 implements 11 differently shaped blocks, each block is composed of three to five spherical modules, spherical modules The included angle is 45 degrees. The eleven blocks can only be arranged flat on the chassis and cannot build a solid shape.

US Patent No. 7,140,612, which is the prior art 3, presents 12 differently shaped blocks, all of the modules of each block are connected at an included angle of 90 degrees, and FIG. 19 shows a three-dimensional four-layer five-sided pyramid, No vertebrae were presented.

Prior Art No. 4, TW M372207, presented in Fig. 7 with 12 different "squares" blocks, each block is connected at a 90-degree angle, the six-layer slope with 54 modules in Figures 18-21 An example of building a triangular pyramid is presented. However, the six-story sloped triangular pyramid can only be configured with 56 modules. The prior art 4 reduces the number from 21 to 21 positioning holes on the chassis, stacking 54 modules with 19 positioning holes. The six-story sloped triangular pyramid was completed. However, the prior art 4 must satisfy the following conditions.

First, there should be 12 "square blocks," and second, the blocks are connected at an angle of 90 degrees. Third, 12 blocks correspond to 54 modules. Fourth, the chassis has 19 position fixing holes.

Since the features are different from the present invention, the structure between the two structures and the functional comparison may be interpreted through comparison tables in the following examples, and thus no further description is made here.

Wikipedia has not published 50 block modules, nor did it reveal how to build a six-story solid triangular pyramid with 12 blocks (56 modules in total) connected at 60-degree included angles. How to do this became a task in this book.

Next, a method of selecting a partial block from 12 blocks and stacking a five-layer slope triangular cone has not been disclosed in the existing patent. Therefore, the realization of this has become a task in the present invention.

The second layer consists of six sides and a pentagon, and the second layer consists of 12 sides and pentagons. It consists of two sides as a group, and the two sides are located on the third layer corresponding to the mirror, above and below the third layer, and above the fifth layer, and the fourth layer consisting of hexagons, and above and below the fourth and sixth layers. A total of 12 faces, which are pentagonal, with two faces in a group, and the two faces correspond like mirrors, but are located on the fifth and symmetrical layers above and below the third and sixth. Pentagonal A block with 50 faces, having a sixth layer symmetrically up and down with the second layer, and a sixth layer below the sixth layer, consisting of a total of one side and hexagonal as a horizontal plane; Is achieved by

The first layer is one, the second layer is three, the third layer is six, the fourth layer is ten, the fifth layer is fifteen, the sixth layer is 21, and a total of 56 Modules.

In order to proceed with the three-dimensional stacking, the first chassis 20a is designed, and as shown in FIG. 7, there are 21 position fixing holes 21 and arranged in an equilateral triangle on the inner and outer rings 22 and 23. Among them, each side of the foreign exchange (23) has six positions fixed, and the included angle of the two sides is 60 degrees.

Next, in order to correspond to each surface of the module 10, 19 surfaces were set in the positioning hole 21, which is the first, second and third floors of the module 10 or the seventh, sixth and fifth. Corresponding to each side of the floor, the distribution is as follows.

9 and 10, when the six-layer slope triangular pyramid stacking proceeds with 12 blocks, and the black arrangement is observed in the six-layer cross section, there are other combination forms other than these two different combination forms. However, only two examples are given due to the limited width.

In the present invention, a block group having a relatively low difficulty was designed, and 7 blocks A to G were selected from the 12 blocks A to L, that is, a first block group 10a was formed. Triangular pyramidal stacking can be carried out (see Figs. 11-14).

11 and 12, 7 blocks (A ~ G) with a total of 35 modules, triangular pyramid stacking can be carried out with four triangular bottom surface, each of the five floors, the number of modules of each floor from above Down as follows.

There are one first layer, three second layers, six third layers, ten fourth layers, fifteen fifth layers, and a total of 35 modules.

As shown in Fig. 13 and Fig. 14, when the five-layer slope triangular pyramid stacking is progressed with seven blocks, and the block arrangement is observed with the five-layered cross section, there are other combination forms other than these two different combination forms. However, only two examples are given due to the limited width.

Next, in order to quickly arrange a five-story slope triangular cone, it is possible to use the fifteen position fixing holes of the first chassis 20a. Of course, the second chassis 20b may be separately designed for the seven blocks, and the structural diagrams are as shown in FIGS. 15 to 17.

15 to 17, the second chassis 20b is provided with 15 position fixing holes 21, the inner ring, the outer ring 24, 25 is arranged in an equilateral triangle, wherein each side of the foreign exchange 25 Five position fixing holes are connected, and the included angle between the two sides is 60 degrees.

The position fixing hole 21 of the second chassis 20b and the position fixing hole 21 of the first chassis 21a are the same, and therefore, each surface distribution situation and shape in the hole will not be described separately.

As shown in Fig. 18, when the stacking is performed between the modules 10, stability is mainly achieved by using "face contact" of each surface of the second and sixth layers, and the top and base surfaces of the first and seventh layers are horizontal. In addition, "face contact" with the chassis or plane can be realized so that it can be easily slipped and stacked without a chassis.

As shown in Figure 19, the module 10 is in contact with the two or three modules 10, when stacked up and down, which is "surface contact", the stability is very high. As shown in FIG. 20, the inner block may be inclined at the position fixing hole 21, and the existing spherical block may not realize this. This proposal realizes the position fixing effect through each side of the 2nd and 6th floors, so that it is convenient for the user's positioning.

Finally, the advancedness in the bone can be confirmed from the following table.
