Description

[Detailed Description of the Invention] The present invention supports a driving wheel on a traveling body via an axle, and locks both ends of a power storage rubber that passes through the center of the axle to the traveling body and the driving wheel, respectively. , relates to a running toy in which the drive wheel is rotated by the twisting force of the force storage rubber, wherein a speed control plate rotatably supported on the axle is interposed between the running body and the drive wheel; It is an object of the present invention to provide a simple and interesting toy in which the rotational speed of the driving wheels, and therefore the running speed of the traveling body, can be switched between high and low levels by simply turning over this speed control plate. shall be.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. In Figs. 1 and 2, 1 is a wooden plate-shaped traveling body disguised as a race car with a driver on board, and idle wheels 2 are attached to the front end of the vehicle. , and the drive wheels 3 are pivotally supported on the rear end side as follows.

The floating wheel 2 is made of a single disk, and is rotatably supported by a front axle 4 protruding from the front end of the traveling body 1.

The drive wheel 3 is made of wood, has a wide configuration by connecting a pair of left and right discs 5.5' to each other via two connecting plates 6 of a certain length, and is located on the side of the traveling body 1. A shaft hole 7 is bored in the center of the inner disk 5.

On the other hand, one end of a hollow rear axle 9 made of synthetic resin and having a flange 9a in the middle part is press-fitted into the shaft hole 8 at the rear end of the traveling body 1, and the flange 9a is connected to a speed control plate (described later). 10 and constitutes a side wall of the traveling body 1 that comes into contact with the traveling body 1.

Further, a drive wheel 3 is rotatably supported in the shaft hole 7 at the other end of the rear axle 9, and the drive wheel 3 and the flange 9
A speed control plate 10 rotatably supported by the rear axle 9 is interposed between the rear axle 9 and the rear axle 9.

The speed control plate 10 is made of synthetic resin, and has a first annular protrusion 11 with a small diameter and a third annular protrusion 13 with a larger diameter that is taller than the first annular protrusion 11 on its side, and an intermediate diameter protrusion on the other side. The second annular protrusions 12 are each integrally molded.

In this case, the first and second annular protrusions 11.12 have a smaller diameter than the flange 9a, and the third annular protrusion 13 has a larger diameter than the flange 9a.

Therefore, the first and second annular protrusions 11.12 can both come into contact with the drive wheel 3 and the flange 9a if the speed control plate 10 is turned over, but the third annular protrusion 13 can contact the drive wheel 3 and the flange 9a.
It is designed so that it can only come into contact with.

The power storage rubber 14 that drives the drive wheel 3 passes through the hollow part of the rear axle 9, and has one end locked to the outer disc 5' of the drive wheel 3 by a suitable locking means, and the other end to the running body. It is locked in a locking pawl 15 protruding from the rear end of 1.

This force storage rubber 14 has a pretension force that draws the drive wheel 3 toward the traveling body 1 and prevents the drive wheel 3 from coming off the rear axle 9.

Next, to explain how to use and function the toy of the present invention, firstly, how to wrap the power storage rubber 14. Hold the drive wheel 3 with one hand, hold the traveling body 1 with the other hand, and hold the rear shaft 9 with the other hand. first in the center
Rotate clockwise in the diagram.

Alternatively, the driving wheels 3 may be rotated backward while being pressed against a running surface G such as a floor or a table.

After storing sufficient power in the power storage rubber 14 in this way, if you place the drive wheel 3 and the idler wheel 2 on the running surface G and take your hands off the toy, the drive wheel 3 will move forward due to the twisting force of the power storage rubber 14. However, since the driving wheels 3 are wide, the plate-shaped traveling body 1 can be driven forward in an upright state.

At this time, the speed control plate 10 is set in the state shown in FIG.
are brought into contact with the driving wheels 3, the friction coefficient between the speed control plate 10 made of synthetic resin and the flange 9a is as follows.
The coefficient of friction between the speed control plate 10 made of synthetic resin and the wooden drive wheel 3 is smaller than that of the first annular protrusion 11 that contacts the flange 9a, and the second annular protrusion 1 that contacts the drive wheel 3.
Since the diameter is smaller than 2, the speed control plate 10 and the flange 9a
The rotational frictional resistance between the speed control plate 10 and the drive wheel 3 is smaller than that between the speed control plate 10 and the drive wheel 3.

Therefore, the speed control plate 10 rotates together with the driving wheel 3, and the first annular protrusion 11 slides and rotates with respect to the flange 9a.

Also, set the speed control plate 10 in the state shown in FIG.
If the annular protrusion 12 is brought into contact with the flange 9a and the third annular protrusion 13 is brought into contact with the drive wheel 3, the rotational frictional resistance between the speed control plate 10 and the flange 9a will control the speed as in the case of FIG. Since the rotational frictional resistance between the plate 10 and the drive wheel 3 is reduced, the speed control plate 10 also rotates together with the drive wheel 3 in this case, and the second annular protrusion 12 slides and rotates with respect to the flange 9a.

However, the rotational frictional resistance R□ between the first annular protrusion 11 and the flange 9a in the case of FIG. 2 and the second
Comparing the rotational frictional resistance R2 between the annular protrusion 12 and the flange 9a, R□<R2 due to the difference in diameter between the first and second annular protrusions 11 and 12.

As a result, the rotational speed of the drive wheels 3, ie, the running speed of the traveling body 1, is fast in the case of FIG. 2 and slow in the case of FIG. 3.

Thus, by simply turning over the speed control plate 10, the running speed of the traveling body 1 can be switched between high and low speeds.

Therefore, as shown in FIG. 1, when the traveling body 1 is disguised as a vehicle that requires speed, the speed control plate 10 is
If set in the state shown in the figure, the traveling body 1 can run quickly to satisfy the above requirements.Also, as shown in FIG. 4, when the traveling body 1 is disguised as a slow-moving animal, By setting the speed control plate 10 in the state shown in FIG. 3, the traveling body 1 can be run slowly to stimulate the movement of the animal.

Incidentally, the modification shown in FIG. 4 uses an eccentric wheel as the idler wheel 2,
Due to the action of this eccentric wheel, the traveling body 1 moves up and down as it moves forward, and the swinging legs 17, which are pivoted on the traveling body 1, swing back and forth, thereby suppressing the jumping motion of the animal. It is something that makes it appear.

As described above, according to the present invention, the traveling body 1 and the drive wheels 3
A speed control plate 10 rotatably supported on the axle 9 is interposed between the speed control plate 10 and the traveling body 1 and drive wheels 3 that contact the speed control plate 10 with different coefficients of friction. On both sides of the speed control plate 10, annular protrusions 11, 12, 13 are provided that change the radius of the abutting portion on the side with the smaller friction coefficient when turned over.
By simply turning over the drive wheel, the rotational speed of the drive wheels, that is, the running speed of the traveling body 1, can be changed to two levels, high and low.
It is interesting because it can easily provide a speed corresponding to the disguise, and it has a simple structure and can be provided at a low price.
