Abstract

PROBLEM TO BE SOLVED: To provide a toy having an effect of making a running toy run around on a ball. SOLUTION: A magnet 5 is provided in an upper part of an inner frame 2 which moves freely inside the ball 1. For the magnet 5 to always face upward, a weight 4 is provided in a lower part of the inner frame 2. In a bottom part of the running toy placed on the ball, a magnet 8 for running toy is provided. The running toy 6 always tends to stay in an upper part of the ball due to the attraction force between the magnet 5 of the ball 1 and the magnet 8 for running toy. When the ball 1 turns, a wheel 8 turns by the friction between the wheel 8 and the surface of the ball 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-riding toy having the effect that a running toy on a ball uses a rotating force of the ball as if it were running on the ball by itself.

[0002]

2. Description of the Related Art Conventionally, there are a variety of toys that operate a traveling toy by using magnetic force, but most of them have a mechanism that moves a traveling toy on a flat plate by moving a magnet provided below the flat plate. Required a complicated device, and there were many restrictions on movement.

[0003]

SUMMARY OF THE INVENTION The ball-riding toy of the present invention has a simple structure, but provides a toy having a visual effect as if the running toy were running on the ball simply by rolling the ball. It is in.

[0004]

The main feature of the present invention is that the traveling toy attached to the ball by the magnet inside the ball and the magnet at the bottom of the traveling toy performs a traveling operation while swinging by rolling the ball. And

BEST MODE FOR CARRYING OUT THE INVENTION

[0005]

FIG. 1 is a sectional view of an embodiment of the apparatus of the present invention. A magnet 5 is mounted on an upper portion of a middle frame 2 which rotates by a rotating shaft 3 fixed to an inner wall of the ball 1, and the magnet 5 always tries to be positioned on an upper side by a weight 4 mounted on a lower portion.

The traveling toy 6 includes a front wheel 8 having a front shaft 7 and a rear shaft 1.
It has a simple structure consisting of a rear wheel 11 having a zero, and a traveling toy magnet 8 is fixed to the bottom. The running toy magnet 8 has a polarity to attract the magnet 5 inside the ball.

Now, when the ball 1 is pushed by hand in a direction perpendicular to the rotation axis 3, the ball rotates but the magnet 5 tends to stay upward, so that the traveling toy 6 also tries to stay at the upper part. The wheels 8 and 11 rotate due to the friction with the wheel 1.

When the ball 1 is pushed in a direction parallel to the rotation axis 3, the ball 1 does not rotate but swings. If the position of the traveling toy magnet 8 is provided on the front wheel side as in the present embodiment, the operation is as if the hips were swung at this time. Since the pushing direction is not actually determined at the time of operation, the traveling toy 6 makes various movements by combining these operations.

FIG. 2 is a perspective view for explaining the internal shape of the ball in the embodiment of FIG. A bearing 1c for fixing the rotating shaft 3 is provided at the center of the left ball 1a, and the same applies to the right ball 1b. 2, 2a, 3, 4, and 5 are the same as those in FIG.

FIG. 3 is a sectional view showing another embodiment. In this embodiment, a spherical middle frame 12 is provided inside the ball 1 and can be moved in any direction by a bearing 13. At least three bearings 13 are required so that the inner frame 12 does not touch the inner surface of the ball 1. In addition, unless the bearing 13 is provided on the upper part, the weight 14 must have a weight enough to overcome the attractive force of the magnet 5. In this embodiment, the traveling toy 6 rotates its wheels regardless of the direction in which the ball 1 is pushed.

FIG. 4 is a sectional view showing another embodiment of the traveling toy. As shown by the broken line in the drawing, the running toy has a body 15 in the form of an animal, and the foot 20 is connected by the crank 19 of the front wheel 16 as shown in FIG. When you put on the, with the movement of the ball 1,
The feet 20 move and appear to crawl on the ball. The rear wheel 17 may be a single wheel as shown in this embodiment. The magnet 21 for the traveling toy on the bottom plate 22 of the main body is also provided.
If the bottom thickness of is not large, the traveling toy magnet 21 can be installed inside the main body as in this embodiment. The method of connecting the crank 19 to the foot 20 in the present embodiment is an example, and various other movements can be performed as long as the load does not exceed the frictional force between the wheel 16 and the surface of the ball 1.

The movement of the running toy looks more effective when the surface of the ball 1 is patterned than when it is a single color.

FIG. 5 shows an example in which a battery 30 and a motor 31 are installed inside the ball 1 and the middle frame 2 is driven by a reduction gear 32 fixed to a rotating shaft 3 so that the ball 1 can be played without being pushed by hand. Show. The magnet 5 and the running toy magnet 8 are the same as those in the above-described embodiment. In the present embodiment, the traveling toy 6
Here is an example in which the shape of the main body is an animal. Battery 3 as shown in FIG.
By disposing the motor 0 and the motor 31 at a position opposite to the magnet 5, the weight 4 is assisted and the efficiency is good.

[0014]

As described above, although the ball-riding toy of the present invention has a simple structure, the traveling toy overlaps with the shaking and performs a complicated movement, which is interesting. The shape of the main body can be developed not only in cars but also in various shapes such as bears, dogs, cats and other animals, as well as frogs and lizards. Also, the magnet 21
If the polarities are unified, a plurality of traveling toys can be used for one ball 1. Further, the running toy can be rolled and played without using the ball 1 itself.
