Abstract

A set of rotationally movable building blocks having flats and building blocks for rotational movement has the following characteristics. That is, the building block consists of two to eight cubes with at least eight corners and twelve ridges. The ridge is set to a sphere and all spheres have the same outer diameter. The flats have equally spaced holes and the holes are recessed holes and the distance between the two holes is equal to the length of one side of the cube. Thus, the sphere of the building block acts with the hole, causing the building block to stand on a flat after the sphere is inserted into the hole. The building block can be rotated 90 degrees forward, backward, right and left on a flat using any two spheres as the axis of rotation. After several rotational movements, the building blocks can be reached from the starting point to the completion point, achieving fun competition and brain training.

Description

Building Base Plates Assembled to Build Blocks Set in Cube Dimensional Configurations}

The present invention involves a design for rotating the building blocks.

The majority of building block designs only move smoothly, but we have invented some kind of rotationally mobile building blocks. Players can show off their skills by reducing the number of movements in this building block set, which also motivates the player.

To rotate a building block, the player must consider the following:

1. Direction of rotation: Consider whether the direction of rotation is straight or oblique. If the rotation is straight, the building block must move on the vertical X axis or the horizontal Y axis. On the other hand, if the rotation is oblique, it must be rotated at an angle of 45 degrees.

2. Rotation angle: If the building block is a cube, it should be rotated 90 degrees. On the other hand, if the building block is flat, it should be rotated 180 degrees. Therefore, the angle of rotation is related to the way of playing.

3. Forms of building blocks: Cubes are made up of various units that are cubes, balls or other forms. Therefore, the shape and number of building blocks change depending on the number and composition of the cube.

4. The shape of the flat: The flat provides the foundation for the rotational movement of the cube. There are various types of flats, such as squares, rectangles, and triangles. If the shape of the flat changes, so does the way the building blocks play.

5. Bump: The bump is installed on a flat. When the number of bumps is added, the game becomes more difficult to play, and the position and number of bumps set in the flat must be preset.

The play of the building block set according to claim 5 has various ways and levels. In this way, the player is motivated and the main theme is how to play the game.

The building block 10 has the following characteristics as a representative component.

The building block consists of at least two to eight cubes having at least eight corners and twelve corners, the corners of which are replaced by protruding spheres 11 having the same outer diameter, and the hole 21 being the flat ( 20 arranged in an array manner and the spheres 11 of the building block 10 work together with the holes 21 to cause the building block 10 to stand upright on the flat 20.

1-4 show diagrams of cubes with the same six sides and the same length of one side of the cube cell. The present invention eliminates other types of cubes and the cubes rotate only 90 degrees without rotating 180 degrees.

1-1, 1-2, and 1-3 show that the building block 10 is composed of two cubes, and the length a of each side of a cube is two holes 21 on the flat 20. It is shown to be equal to the distance (b). The relation of length is (a) = (b), so that each sphere 11 of the building block can coincide with each hole 21 on the flat.

The shapes of the cubes vary as mentioned above, as shown in FIG. 21, where there are eight different building blocks 101 to 108 and the width W of each building block is the distance b between the two holes. , Which is represented by the formula (W) = (a) = (b)

The length L of the block is different from the height H of the block. The length is as follows.

The length L of the blocks 101 and 103 is equal to the length a of one side of the cube, which is also equal to the distance b between the three holes 21, which is the equation (L) = 2 (a). It is expressed as = 2 (b).

The length L of the blocks 102, 104, 106 is equal to the length of three cube cells and the distance between the four holes 21, which is the equation (L) = 3 (a) = 3 (b )

The length L of the blocks 105, 107, 108 is equal to the length L of the four cube cells and is also equal to the distance between the five holes, where (L) = 4 (a) = 4 (b )

The height is

The height H of the blocks 101 and 102 is equal to the height H of one cube cell and the distance between the two holes 21 and is represented by the formula (H) = (a) = (b). .

The height H of blocks 103 to 108 is equal to the height H of two cube cells and equal to the distance between the three holes 21, represented by equation (H) = 2 (a) = 2 (b). do.

As described above, each hole 21 on the flat 20 corresponds to the arc-shaped groove 25 and the arc-shaped groove 25 corresponds to the arc-shaped pipe 13, so that the arc-shaped pipe 13 at the time of rotational movement of the building block. ) Is placed on the arc-shaped groove 25. If there is no arc tube 13, the arc groove 25 is also not needed.

As described above, the building block 10 rotates the two spheres 11 on the rotational axis on each corner line, and can only rotate 90 degrees without any other angle rotation. This can be seen from Figures 2-1 to 2-6. 2-1 to 2-6, (A) represents the starting point and (B) is the completion point of the building block 10. The starting point and the completion point are designated by the player, and the building block 10 must reach the completion point B from the starting point A through several 90-degree turns. For example, there are various ways to play a game starting from FIG. 2-1, starting point A, and reaching FIG. 2-6, completing point B. FIG. The winner is the player who finishes the game with minimal rotational movement. The diagram shows only one way to play, and the difficulty of the game changes as the starting and finishing points change.

The building block 10 has the following characteristics.

1. The building block is a cuboid and consists of at least two cubes.

2. The building block rotates to the 90 degree position.

3. The building block can only move straight, for example rotated to the front, rear right and left, excluding 45 degree diagonal rotational movement.

4. The building block is rotatable about two spheres 11 overlying each of the two holes 21 of the flat 20.

In addition, the corners of the building blocks are replaced with protruding spheres 11, whereby the building blocks have the following characteristics.

1. The sphere 11 is easy to put in the hole 21 of the flat 20, whereby the surface of the building block 10 can be disposed on the flat 20.

2. The hole 21 is a shallow arc shape, so that it is easy to rotate the sphere 11 without any trouble.

3. Since the sphere 11 is located in the hole 21, it is not easily rotated. Therefore, the sphere 11 is disposed in the hole 21 stably even when the flat 20 is shaken.

4. The protruding sphere 11 meets the safety function and protects the building block from scratches.

In addition, the ridge of the building block 10 is replaced by a protruding arc tube. Accordingly, the building block has the following characteristics.

 1. The arc tube 13 is easy to fit into the arc groove 25 of the flat so that the surface of the building block 10 can be located on the flat 20.

 2. The arc tube 13 is not easily rotated in the arc groove 25, so that even if the flat 20 is shaken, the arc tube 13 is disposed in the arc groove 25 in a stable manner.

 3. The protruding arc tube meets the stability function to prevent scratching and ensures that there is no sharp side of the building block 10 in appearance.

3 and 4 show the movement of the building block, FIG. 3 shows the starting point A and the completion point B of the building block 10 on a diagonal line, and FIG. 4 shows a non-diagonal building. The starting point A and the completion point B of the block 10 are shown. From both embodiments, it can be seen that the starting point A and the finishing point B can be located anywhere on the flat 20 without being limited to the examples of FIGS. 3 and 4, and the player starts Point A and completion point B can be determined. When the player moves the building block 10 from the starting point A to the completion point B, the game ends and the player with the least number of rotational movements is the winner. In this way, the game can motivate the player by giving the player fun, creativity and competition.

FIG. 5 shows two bumps 22 disposed on the flat 20 and obstructing the building block 10. Bump 22 is disposed between the four holes 21, the area of the bump 22 is the same as the upper surface of one cube unit.

The shape of the bumps 22 is not limited but the height is determined only by the length a of one side of the cube cell, and the number of bumps 22 should be at least one unit. The number of bumps 22 can be added and the game will be more difficult as the number of bumps 22 added to the rotatable building block 10 on the flat 20 increases. The position of the bump 22 may be fixed or non-fixed, and in the case of non-fixed the position of the bump 22 may be anywhere on the flat.

Referring to FIG. 6, the bump 22 serves as an obstacle of the game, and the inventor sets a gap 12 in the building block 10 to give fun and creativity to the game. For example, in FIG. 6, the building block 10 consists of five cubes and includes one gap 12 on the outside, the area of the gap 12 being equal to the area of the bump 22. Accordingly, the gap 12 may be released from the obstruction of the bump 22 or may be diverted to both sides of the bump 22 to the completion point B during the rotational movement of the building block 10. The building block 10 'of FIG. 6 represents the completion point of the game.

Referring to FIG. 7, two bumps 22 according to FIG. 6 are flat and the sum of the bumps 22 is four in total. Building block 10 must avoid four bumps 22 while starting from starting point A to completion point B, where building block 10 may bypass both sides of bump 22. Or the gap 12 may be used to escape the bumps 22. The difficulty of FIG. 7 is higher than FIG.

It can be seen from the concept that the game in which the bump 22 is set will be more difficult than the game in which the bump 22 is not set. As the number of bumps 22 increases, the difficulty of the game also increases. In addition, the building block 10 is composed of cubes of 2 to 8 units, and as the number of cubes increases, the volume of the building blocks 10 also increases, making the game more difficult, and a gap 12 is added to the building block 10. Each time it is set to, the fun of the game also increases.

In order to move the bump 22 freely on the flat 20, the bump 22 is made of a movable part. That is, the bump 22 can be changed in position on the flat 22. As shown in FIG. 7, the flat 20 is configured such that the center of the square consisting of four holes 21 is the hollow portion 23, and the lower portion of the bump 22 is inserted into the hollow portion 23. Although not mentioned herein, there may be a variety of ways of insertion, and the bump 22 may be removed from the hollow to change its position for the purpose of motivating the player.

As described above, the bumps 22 act as obstacles on the flat and may be set in the manner of FIG. 8, as shown in FIG. 8, where the front and back of the card 30 are numbered Arabic numerals or symbols. There is a sign 31. For example, there is a marker 31 made of Arabic numerals, and two or more of them are selected as the virtual bump 32. The virtual bump 32 is shown by placing round brackets on the Arabic numerals. The card 30 functions with the flats and FIGS. 9 and 10 illustrate this.

9 and 10 are exploded views and conceptual views of the card and the flat. In FIG. 9, the card 30 is located below the flat 20 and the mark 31 of the card 30 corresponds to each hollow part 23. Therefore, the player can see the marker 31 through each hollow part 31 of the card 30, as shown in FIG. 11, and the virtual bump (using the gap 12 during the rotational movement of the building block 10). It may be possible to escape the obstruction of 32 or bypass both sides of the virtual bump 32. Thus, it can be seen that the bump 22 can be replaced by the virtual bump 32 of the card 30.

FIG. 12 is a view of the flat and the card which are visible to the naked eye, and FIG. 12 differs from FIG. 11 in that there is no hollow 23 in the flat 20. The card 30 is located below the flat 20 and each marker 31 of the card is located between all four holes 21 arranged in a matrix. Thus, the player can visually identify the marker 31 and the virtual bump 32 through the transparent flat 20 placed on the card 30. The structure can be described in FIG.

In FIG. 13, the card 30 is located below the flat 20, and the plurality of marks 31 written on the card 30 are located between four holes arranged in a matrix form. In FIG. 14, the flat 20 When the card 30 is combined with the player, the player may see the mark 31 and the virtual bump 32 on the card 30 through the hole 21. The virtual bump 32 may be replaced with the actual bump 22.

As described above, the bumps 22 and the virtual bumps 32 are obstacles of the building block 10, and as shown in FIG. 6, may be a starting point and a completion point. Since the two bumps 22 can be the starting point and the completion point of the building block 10 on the flat 20, the virtual bump 32 is also the starting point and the completion point of the building block 10 on the flat 20. This can be
