Description

The present invention relates to a top toy. In particular, it relates to multiple tops with different rotation directions at the top and bottom.

FIG. 12 shows an overall perspective view of a conventional toy used by children for play. A self-contained body 11 and a top axis 15 are provided above and below the center of the substantially conical body 11, and the top body 15 is rotated by the thumb and forefinger to rotate the top body. Therefore, the conventional top is only one-way rotation.

Further, the shaft 15 on the surface side that comes into contact with the spinning of the top is manufactured from a material different from that of the conical body 11, and a hole is formed in the center of the conical body, and the tip is pointed. Some have a conical shape, and others have the shaft core 15 manufactured by cutting or the like integrally with a conical body.
The reason why the shaft core shape and the shaft core are made to be the center axis of the top is to reduce precession during rotation of the top as much as possible.

Further, in Patent Document 1, the shape up to the tip of the head is a hemisphere, an ellipsoid, or a foggy shape having a tip, and the bottom shape is a sphere so that the top is kept tilted by precession, and the center of gravity There is also a predation-based topography that looks like a big top spinning around the center, and when the top is stationary, the pattern on the rotating body looks the same as when stationary. is there.

However, since the above-mentioned conventional top is only one-way rotating operation, there is a lack of fun as a toy.

In order to solve the above-described problems, the present invention stacks a plurality of rotating tops, and the center axis of the spherical body 13 which is a spherical contact portion made of a part of a sphere or an elliptical sphere coincides with the center axis of the top So that the integrated center shaft penetrates the central shaft on one side, the shaft hole is provided on the other side, and the lower shaft of the lowermost top is the hole on the top of the top Inserted loosely inside, the top top can be attached to and removed from the shaft center or shaft hole of the bottom top so that the center axis of the top top matches the center hole of the top top. A rotating top is applied by strongly applying one of the lower top or the top top, and the adjacent lower top and top tops rotate in different directions. The most important feature is to provide.
Since the shaft core 15 is loosely inserted into the hole of the top plate and the adjacent shaft hole 16 and the spherical body 13 actively utilizes the precession while contacting the periphery of the hole, The top and top solos have opposite directions of rotation.

As described above, in the present invention, adjacent tops are rotated in opposite directions, and thus cannot be obtained from the prior art by attaching feathers or ornaments to the multiple tops or by devising colors and patterns. New effects can be obtained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that components with similar functions or structures are given the same names and symbols as much as possible, and necessary explanations are given for the first appearance, and only when there are changes or feature points when reappearing .

FIG. 1 shows a triple top as an example of the multiple top of the present invention. As shown in FIG. 1, the multiple top solo of the present invention comprises a bottom single top 1, a single top 2, an upper single top 3, and a support base.

FIG. 2 is a longitudinal sectional view showing an example of a single top unit 10 constituting the multiple top music in FIG. The spherical body 13, which is a spherical contact portion formed of a part of a sphere or an elliptical sphere, is integrated so that the central axis of the spherical body 13 coincides with the central axis of the top body 11, and penetrates the integrated central axis on one side. A shaft core 15 is provided, and a shaft hole 16 is provided on the other side. The cylindrical shaft column 14 is a member for making the shaft hole 16.

In addition, the top body 11 is provided with a hand-drawn convex portion 12 for applying a rotational force to the top. The hand-playing convex portion 12 may be provided on at least one of the single tops constituting the multiple tops. Further, the hand repelling convex portion 12 provided in the single top must be provided in an arrangement that does not impair the rotational balance. Therefore, it becomes two or more.
Moreover, what is necessary is just to provide in the vertex of a regular polygon in order to make the arrangement | positioning which does not impair rotation balance.

The lower shaft core 15 of the lowermost top 1 is loosely inserted into the hole of the support base 21 of the support base 20 so that the upper top matches the central axis of the upper top with the shaft hole 16 of the lower top. The provided shaft core 15 is detachably arranged on the same axis, and a rotational force is applied by strongly repelling one of the tops constituting the multiple tops.

The support base 20 needs to have a size and a weight suitable for the number and weight of the multiple tops to support the entire multi-stage top, and the support base hole 21 penetrates the upper and lower surfaces of the support base 20 in this example. However, it does not necessarily have to penetrate.

When the support base hole 21 does not penetrate vertically, and the lower part is closed in the middle, the spherical body 13 of the lowermost top is in contact with the wall surface of the support base 20 around the support base hole 21 while precessing. In order to make the movement, the depth of the support base hole must be deeper than the length of the shaft core 15 protruding from the spherical body 13 of the lowermost top.

Next, the operation principle of the multiple top music of the present invention will be described.
FIG. 9 is a diagram for explaining the operation principle of the present invention. It is assumed that the columnar rotating body 52 rotates in the CW direction. At this time, it is considered that the columnar rotating body 52 rotates in contact with the cylindrical inner wall 51 as illustrated. In this case, the columnar rotating body 52 moves while rolling on the cylinder inner wall 51 due to contact friction with the cylinder inner wall 51, and the locus of the center point of the columnar rotating body 52 is a circular motion in the CCW direction.

FIG. 3 is a longitudinal sectional view showing the operation principle of the present invention.
In FIG. 3, the top unit 10-1 is the bottom unit top unit 1, and when the hand-playing convex portion 12 of the top unit 11 is repelled in the CW direction, the top unit 10-1 is inclined as shown in the CW direction. Rotate. In other words, it is rotating while precessing.
Therefore, the spherical body 13-1 provided on the lower side of the top unit 10-1 rotates while rolling on the wall surface of the upper surface of the support base 20. That is, according to the principle described in FIG. 9, the locus of the center of the tip of the cylindrical shaft column 14-1, that is, the center of the shaft hole 16-1, is a circular motion in the CCW direction.

As shown in FIG. 1, the spherical body 13-2 of the single top 2 is formed as a single top if the shaft 15-2 of the single top 2 is loosely inserted into the shaft hole 16-1 of the bottom top unit 10-1 shown in FIG. It rotates in the CCW direction while rolling on the upper surface of one cylindrical shaft pillar 14-1, and the locus of the center of the shaft hole 16-2 of the single top 2 is a circular motion in the CW direction.

Similarly, if the core 15-3 of the single top 3 is loosely inserted into the shaft hole 16-2 of the single top 2 as shown in FIG. 1, the spherical body 13-3 of the single top 3 becomes the cylindrical shaft column of the single top 2 It rotates in the CW direction while rolling the upper surface of 14-2, and the locus of the center of the shaft hole 16-3 of the single top 3 is a circular motion in the CCW direction. Therefore, the adjacent lower top and upper top perform different rotational movements. However, when the top speed of the top is fast, the adjacent bottom top and top top perform different rotational movements, but the friction resistance between the shaft core 15 and the shaft hole 16 is low speed before the stop. Is stronger than precession, so the adjacent lower top and top top may rotate in the same direction.

As described above, the lowermost top and the support stand 20, and the adjacent lower and upper tops rotate while rolling on the wall surface in contact with the spherical body 13, that is, precession and rotation occur. In order to achieve this, a dimensional relationship is required such that the support base hole 21 of the support base 20 and the bottom core shaft 15 of the lowermost drum, and the shaft hole 16 of the lower top band and the upper core shaft 15 can be loosely inserted. . Specifically, if the outer diameter of the shaft core 15 is 100, the inner diameters of the support base hole 21 and the shaft hole 16 are 110 to 130, and the optimum value is 120.

The top body 11 may be not only a disc shape but also a plurality of impeller (propeller) shapes as shown in FIGS. 10 (a), 10 (b), and 10 (c). But it ’s okay.
Further, when the impeller shape is used as the top body 11, the center lines of the plurality of impellers are made to coincide with the lines connecting the centers of the regular polygons and the vertices in order to achieve dynamic balance as a rotating body.

There are basically no restrictions on the material of each part constituting the multiple topography shown in FIG. However, it is preferable that the lower rotating top 1 for mainly hand-playing and turning is made of a material that is heavier than the upper rotating top 2. The same applies to the support base.

FIG. 1 shows a triple top as an example of a multiple top configuration according to the present invention. A specific embodiment will be described.
The top body 11-1 of the bottom single-piece top 1 is made by punching a metal plate in order to increase the inertia at the time of rotation, and the hand-playing convex portion 12-1 of the top body is a dynamic balance at the time of rotation. Four are provided at 90 ° positions, which are the vertices of a regular tetragon.

The solo main body 11-2 of the single solo music 2 is made of plastic. The top body 11-3 of the upper single top 3 is also made of plastic. The solo main body 11-2 of the single top 2 has a larger outer diameter and thickness than the top main body 11-3 of the top single top 3, and has a greater inertia during rotation than the top single top 3.

Also, the outer diameter of the upper top is successively made smaller than the outer diameter of the lower top so that each of the three singles of the triple top can be clearly seen. If the outer diameter of the main body 11-1 of the lowermost top solo 1 is set to 100, the balance of the appearance is good when the outer diameter of the main body 2 of the single top 2 and the upper single top 3 is set to about 60 and 35.

In addition, the support base 20 needs an appropriate weight in order to support the entire triple music, and the material is brass in this embodiment.
Since the spherical body 13 rotates while rolling on the wall surface of the upper surface of the support base 20 as described in the operation principle, the support base hole 21 of the support base 20 improves the rolling of the wall surface as shown in FIG. A support base hole chamfered portion 22 is provided at a contact portion with the base plate.

Also in this embodiment, as described above, if the outer diameter of the shaft core 15-1 is 100, the inner diameters of the support base hole 21 and the shaft hole 16-2 are 110 to 130, and the optimum value is 120.
In addition, the upper top 2 is set to be slightly tilted with respect to the lower top 1 like a hat on the head.

In FIG. 4, if the hand-playing convex portion 12-1 of the top body of the bottom top 1 is repelled in the CW direction, the bottom top 1 tilts and rotates in the CW direction. In other words, it is rotating while precessing. Accordingly, the axis 15-1 of the top 1 performs a precession while drawing a locus in the CCW direction. As a result, the top 2 also rotates in the CCW direction.
Therefore, in the embodiment shown in FIG. 4 as well, the lower top 1 and the upper top 2 can realize a double-revolution top with reverse rotation.
In the double spinning top shown in FIG. 4, the top and bottom top 2 are rotated in opposite directions even if a rotational drive input is performed by hand-playing, realizing the double spinning top. Is done.

Although the lower top 1 is not different from the configuration of FIG. 4, the shaft core 15-1 of the lower single top 1 passes through the shaft hole 16-2 of the upper single top 2.
Therefore, in this case, a cylindrical shaft pillar 14-2 having a shaft hole 16-2 passing through is provided on the side in contact with the lower top 1 so as to maintain an appropriate space between the upper and lower tops 1 and 2, and the portion in contact with the lower top 1 Is provided with a spherical body 13-2.
Even in this configuration, if the hand-pulling portion 12-1 of the top body of the bottom top 1 is repelled and a rotational driving force is applied, the top and bottom top and bottom tops 1 and 2 rotate in opposite directions, and a double-rotation top Realized.
Also in this embodiment, even if the upper top 2 is subjected to rotational drive input by hand-playing, the top and bottom tops 1 and 2 rotate in opposite directions to realize a double-rotation top.
