Description

[Detailed Description of the Invention] The present invention relates to a wheelie toy that can wheelie with good straightness even on uneven running surfaces.

2. Description of the Related Art Traveling toys are one of the most popular types of traveling toys, and many types of traveling toys have been put into practical use to date. One such example is a toy that runs on a wheelie, and the present invention is an excellent technical improvement to such a toy that runs on a wheelie. That is, in the present invention, both sides of the axle of an auxiliary wheel for wheelie running are supported by vertical holes provided at the rear of the toy body, and the central part of the axle is brought into contact with a control member, so that both sides of the axle are The object of the present invention is to provide a wheelie running toy that can wheelie with good straightness even on an uneven running surface by supporting the parts so as to be swingable in the vertical direction within respective longitudinal holes.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 is an overall perspective view of the vehicle with the auxiliary wheels removed from the vehicle body, FIG. 2 is an enlarged perspective view of the main parts, and FIG. 3 is a side view of the vehicle in wheelie mode.

In these drawings, reference numeral 1 denotes a vehicle body imitating the shape of an automobile, which has front wheels 2 and rear wheels 3, and is equipped with a drive unit 4. As the drive unit 4, various types can be used, such as one having a built-in motor, a battery, and a power transmission mechanism, or one having a built-in spring and a power transmission mechanism. The drive unit 4 has an outer shape that resembles an automobile engine, and a portion thereof protrudes from the rear of the vehicle body 1.

11a and 11b are supporting members, which support the drive unit 4.
It protrudes from both sides of the lower part, and vertically elongated holes 12a and 12b are provided correspondingly in the diagonal direction at the tip of each. Both vertical holes 12a and 12b are
Each has the same shape and length, and the car body 1
The elongated portion of the hole is formed so as to be located in the vertical direction perpendicular to the running surface when the vehicle is tilted backward to perform a wheelie. 13a and 13b are auxiliary wheels that touch the running surface during wheelie;
It is fitted onto both ends of the axle 14. The axle 14 has a diameter smaller than the short portions of the longitudinal holes 12a, 12b, and is pivotally supported on both sides near the auxiliary wheels 13a, 13b by the longitudinal holes 12a, 12b.

Reference numeral 15 denotes a control member located approximately in the center of both support members 11a and 11b, and the lower surface 15a is formed into an arc shape or an angular shape, and the drive unit 4
It protrudes from the center of the bottom. This control member 15
The lower surface 15a is in contact with the upper surface of the central portion of the axle 14 to act as a fulcrum, allowing both sides of the axle 14 to swing up and down in opposite directions within the vertical holes 12a and 12b. .
Therefore, when one auxiliary wheel 13a descends, the other auxiliary wheel 13b rises by that amount using the control member 15 as a fulcrum.

In the wheelie toy having such a configuration, the auxiliary wheels 13a, 13 are
When b rides on the uneven running surface, the control member 15
The left and right auxiliary wheels 13a and 13b swing in the vertical direction using the fulcrum as a fulcrum, and while always maintaining balance, they touch the ground on the running surface and rotate smoothly. In addition, support member 1
1a, 11b, vertical holes 12a, 12b, axle 14
Or the support members 11a, 11b and the control member 15
Even if there is a machining error or distortion in the drive unit 4 etc., the left and right auxiliary wheels 13a, 13b will not run because both sides of the axle 14 swing vertically within the vertical holes 12a, 12b. It makes contact with the surface and rotates smoothly. Therefore, even during wheelie running, the vehicle performs wheelie running with good straightness.

Note that the present invention is not limited to the embodiments described above, and can be modified as follows, for example. That is, the supporting members 11a, 11b
In the case where the drive unit 4 is completely built into the vehicle body 1, the control member 15 is connected directly to the vehicle body 1.
It is also possible to provide it at the rear of the It is also possible to provide the vertical holes 12a, 12b directly in the vehicle body 1 or the drive unit 4. Therefore,
The toy body referred to in the present invention includes not only the car body 1 but also other components such as the drive unit 4, and
This is a general term for cases in which support members 11a and 11b are provided. In addition, the axle 14 is not limited to a columnar one with the same diameter over its entire length, but also one with a flattened central part, one with a large diameter, or one with a vertically long hole 12a,
This also includes those in which the portion that is pivotally supported by 12b has a small diameter. Furthermore, the contact relationship between the control member 15 and the axle 14 is not limited to the one in which the control member 15 contacts the upper surface of the axle 14, but also the control member 15 having a hole in the center of the axle 14, in which the protruding control member 15 is inserted. It also includes those that are inserted and brought into contact.

As described above, according to the present invention, both sides of the axle of the auxiliary wheel are supported by the longitudinal holes provided at the rear of the toy body, and the central part of the axle is brought into contact with the control member, and both sides of the axle are By supporting the auxiliary wheels so as to be able to swing up and down in the respective vertical holes, the auxiliary wheels can be reliably grounded and rotated smoothly, and the straightness of running during wheelie can be improved.
