It has a double structure.

[0008]

Example 1 By the way, in this example, the outer shell 3
Has a structure in which an upper half body 3a and a lower half body 3b are combined, and the inside of these upper half body 3a and the lower half body 3b is combined to form a hollow portion 2. Inside the body 2, the rotary shaft 4 is vertically positioned so that the protruding portion 1 provided on the lower surface of the lower half 3b is located directly below, and the friction rotary body 5 is provided with the outer shell by combining the upper half 3a. It is constructed so that it can be installed concentrically with the body 3. Further, the upper half body 3a and the lower half body 3b are integrated by fitting a plurality of protrusions 3c provided in the upper half body 3a into a plurality of holes 3d provided in the lower half body 3b (see FIG. 3). See)) is configured. In addition, a plurality of wing-shaped projections 3e are provided on the outer periphery of the upper edge of the lower half 3b, and a large centrifugal force is obtained when the outer shell 3 rotates, and a plurality of tops are rotated to increase the rotation strength. When competing, it employs a configuration that allows the tops that come into contact with it to be blown away.

A rack for meshing with a pinion 6 provided on the outer circumference of the rotary shaft 4 of the friction rotary body 5 is provided on either the left or right side of the upper half body 3a which is a constituent member of the outer shell body 3. A groove portion 8a that forms a hole 8 for inserting 7 is integrally formed (see a in FIG. 1).
Further, a downward opening hole is formed in the center of the protrusion 1 at the center of the outer peripheral lower surface of the lower half 3b of the outer shell 3 (in this embodiment, for example, the tip of a mechanical pencil of about 0.5 mm is pierced). 9) is provided.

The rack 7 for engaging with the pinion 6 provided on the outer circumference of the rotary shaft 4 of the friction rotary body 5 is formed in an elongated shape so that it can be easily inserted into the hole 8 provided in the outer shell body 3 (see FIG. 1), a ring 7a is formed on one side of the rack 7 for easy holding. The assembly and rotation operation of the top described above will be described in detail below.

The assembly of the top according to the present invention is carried out by the outer shell 3
The rotating body 5 is arranged inside the lower half 3b constituting the. In this arrangement, the rotary shaft 4 is located at the center of the lower half 3b. Next, the upper half 3a is united. In this case, the upper half 3a and the lower half 3b are combined by fitting the plurality of protrusions 3c provided on the upper half 3a into the plurality of holes 3d provided on the lower half 3b. As a result, the rotary shaft 4 of the rotating body 5 arranged inside the lower half 3b is held vertically inside the hollow portion 2 of the outer shell 3b.

When the top thus assembled is rotated and played, first, as shown in FIG. 3, the hole 8 provided in the outer shell 3
Insert the rack 7 deep into. By inserting the rack 7, the pinion 6 provided on the outer periphery of the upper portion of the rotary shaft 4 of the rotary body 5 concentrically incorporated in the hollow portion 2 of the outer shell 3 meshes with the rack 7. When the insertion of the rack 7 into the hole 8 is completed as described above, next, the outer periphery of the outer shell body 3 is firmly grasped by hand, the ring 7a at the hand of the rack 7 is firmly grasped, and the rack 7 is vigorously pulled out. As a result, the rotating body 5 arranged inside the outer shell 3 starts to rotate. In this state, the outer shell 3 is still held by the hand, and only the rotating body 5 is rotating at high speed.

Finally, the outer shell 3 is released from the hand.
In the initial state, the outer shell body 3 separated from the hand is in an unstable rolling state because the rotational inertia of the inner rotary body 5 is not sufficiently transmitted, but after a while, the rotary body 5 is rotated. Since the rotational inertia of 1 is sufficiently transmitted to the outer shell body 3, the outer shell body 3 also follows the rotating body 5 and starts rotating at high speed.

As for play, even one piece can be played sufficiently, but as shown in FIG. 4, when two or more pieces are brought close to each other and rotated, the tops come into contact with each other.
Due to a difference in rotational force or a difference in contact angle, one of the tops is moved farther by the other top. Further, in the above-described embodiment, the tip 10a of the mechanical pencil 10 (see FIG. 5) is provided in the hole 9 provided in the protrusion 1 on the lower surface of the outer shell 3.
You can play acrobatic tops by sticking.

As described above, according to the top of the present invention, the outer shell body is provided with the projecting portion at the center of the lower surface of the outer periphery and the inside is formed in the hollow portion, and the top shell is arranged in the hollow portion of the outer shell body. And a friction rotating body concentrically arranged with the outer shell body with its rotation axis positioned vertically so that the protrusion provided on the lower surface of the outer shell body is located directly below the outer shell body. By constructing the body into a united structure of an upper half body and a lower half body, the method of assembling is facilitated, and the lower half of the outer shell body has a downward opening at the center of the projecting portion at the center of the outer peripheral lower surface. Make a hole,
A rack in which play is widened, and the rotation of the friction rotator disposed in the hollow portion of the outer shell is inserted through a hole provided in the outer shell into a pinion provided on the outer periphery of the rotation shaft of the friction rotator. Since it is configured so that rotation can be easily performed by engaging with, and pulling out the rack, when playing with spinning top, insert the rack deeply into the hole provided in the outer shell and force the rack vigorously. By pulling out, it is possible to give a high speed rotation to the rotating body, transmit the rotational inertia of the rotating body to the outer shell, and perform top play. As for play, even one piece can be played well, but if two or more pieces are brought close to each other and rotate, the tops will come into contact with each other, so either one will be different due to the difference in rotational force or the contact angle etc. One top can play, such as skipping the other top. Moreover, since the center of rotation is the rotating body incorporated inside the outer shell, the inertial rotation of the outer shell is stopped even if the outer shell is directly gripped by the hand during play. Therefore, it has various effects such as safe and enjoyable play without damaging the grasped hand.
