Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a frame whose rotation characteristics change between low-speed rotation and high-speed rotation.

[0002]

[Prior art and its problems]

 Conventionally, top toys have been very popular in children's play, and friends can hit each other's top toys, defeat opponents' top toys, or flip out of a designated game space (game board). Games for fighting are common.

[0003] At present, there are many such top-games in which various tastes are elaborated. For example, a top toy is configured to be disassembled, and parts are exchanged to change a rotation characteristic so that a game can be played. Advantageously tune-ups have been proposed. As described above, many conventional ones emphasize rotation, such as those that stabilize the rotation of the toy frame and those that make the rotation faster.

[0004]

[Problems to be solved by the invention]

 However, if the rotation characteristics are changed by replacing parts, it is burdensome for the child because the parts must be purchased. In addition, in the game of competing against each other by colliding each other with toys, there is a problem that it is not desirable as a toy for children, in which the one who wins costs wins.

[0005] An object of the present invention is to provide a top toy capable of solving the above-mentioned problems and obtaining two kinds of rotation characteristics with one piece.

[0006]

Means for Solving the Problems In order to solve the above problems, a top toy according to the present invention has the following requirements. (B) A magnet is provided inside. (B) A cylindrical portion is formed in the center of the lower surface, and a magnetic core material having magnetism is disposed inside the cylindrical portion. (C) On the opposite side of the cylindrical portion, a notch for exposing the magnetic core material is formed, and outside the notch, an iron ball is attached to the magnetic core material. There is a storage section that can be moved so that it can move toward and away from

Preferably, an iron ball is rotatably fitted to the lower end of the cylindrical portion.

[0008] The toy body is preferably formed of at least three layer members, of which the intermediate layer member is a weight.

[0009]

[Embodiment of the invention]

 1 and 2 are a perspective view and an exploded perspective view of a top toy. This top toy is composed of a lowermost layer member 1, a lower layer member 2 disposed above the lower layer member 1, and an upper layer member 3 disposed above the lower layer member 2. The middle member 2 is a metal weight. Both the upper layer member 3 and the lower layer member 1 are made of synthetic resin. By adopting the weight, the rotation of the top toy is strong and the stability increases.

[0010] The above-mentioned toy having a multilayer structure is known, and assembly and disassembly may be performed as known. The top toy may be composed of three or more layers by three or more layer members. By changing the members of each layer, complicated rotation characteristics can be obtained.

A storage section 4 is provided at the upper center of the lower layer member 1, and the storage section 4 is fixed to the lower layer member 1 by an insertion piece 1 a. As shown in FIG. 3, the magnet 5 is housed and arranged inside the housing 4. The housing 4 is open downward, and a part of the magnet 5 is exposed downward.

Next, as shown in FIG. 3, a cylindrical portion 6 is provided at the center of the lower surface of the lower layer member 1, and a magnetic core material 7 having magnetism is arranged inside the cylindrical portion 6. . The upper end of the magnetic core 7 is in contact with the magnet 5. As shown in FIG. 4, a ball 8 (made of metal or hard synthetic resin) is rotatably fitted to the lower end of the cylindrical portion 6. As described above, since the ball 8 is structured to be held by the cylindrical portion 6, it is difficult to lose it, and it is possible to prevent the baby from swallowing easily.

Further, as shown in FIG. 3 and FIG. 4, notches 9 are formed on the opposite sides of the cylindrical portion 6 so that the magnetic core 7 is exposed from these notches 9. It has become. Outside the notch 9, a storage portion 11 for an iron ball 10 is formed. The storage section 11 is formed by an upper projection 12 projecting from the lower surface of the lower layer member 1 and a lower projection 13 projecting from the cylindrical section 6. In short, the storage section 11 only needs to be configured so that the iron ball 10 inside does not fall off. In addition, the iron ball 10 can be moved in the direction of approaching and separating from the magnetic core material 7 by the above-described storage portion configuration.

According to the above configuration, when the top toy is rotated on an amusement board by an appropriate shooter or the like, the top toy rotates about a rotation axis passing through the centers of the ball 8 and the magnetic core 7. Since the ball 8 is rotatable, the rotation resistance with the board surface is small. Therefore, the rotation becomes sticky and keeps turning for a long time.

By the way, since the magnetic core 7 inside the cylindrical portion 6 is in contact, the magnetic core 7 is magnetic. For this reason, the iron ball 10 is attracted by the magnetic force of the magnetic core 7, and is attracted to the magnetic core 7 when not rotating.

However, as soon as the top of the toy starts to rotate, the number of rotations increases, and when the toy rotates at high speed, as shown in FIG. 5, the centrifugal force due to the rotation is greater than the attraction force due to the magnetic force. The iron ball 10 becomes stronger, and moves so as to be separated from the magnetic core 7 in the storage portion 11. For this reason, the rotational force increases.

On the other hand, when the iron ball rotates at a low speed, the iron ball is attracted to the magnetic core material 7 because the magnetic attraction force is stronger than the centrifugal force. For this reason, rotation stability is improved.

Of course, even when the iron ball 10 moves from the low-speed rotation to the high-speed rotation, or shifts from the high-speed rotation to the low-speed rotation, the iron ball 10 approaches or separates from the magnetic core material 7.

As described above, since two different rotation characteristics can be obtained with one piece toy, two parts are not required. Therefore, it is possible to provide a toy having two different functions at a low price.

[0020]

[Effect of the invention]

 According to the invention of claim 1, the number of revolutions increases soon after the top of the toy starts to rotate, and when the toy rotates at a high speed, the centrifugal force due to the rotation is stronger than the attraction force due to the magnetic force. The iron ball moves so as to be separated from the magnetic core material in the storage section. For this reason, the rotational force increases. On the other hand, when the iron ball rotates at a low speed, the magnetic ball attracts the magnetic core material 7 because the iron ball has a stronger attractive force due to magnetic force than centrifugal force. For this reason, rotation stability is improved. As described above, since two different rotation characteristics can be obtained with one piece toy, two parts are not required. Therefore, a toy having two different functions at a low price can be provided.

According to the second aspect of the present invention, since the iron ball is rotatable, the rotation resistance between the iron ball and the board for rotating the top toy is small. Therefore, it keeps turning for a long time.

Further, since the iron ball is structured to be held by the cylindrical portion 6, it is difficult to lose the iron ball, and it is possible to prevent the baby from swallowing easily.

According to the third aspect of the present invention, more complicated rotation characteristics can be obtained by replacing the members of each layer.
