Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a non-twin-wheel steered vehicle which automatically steers the vehicle to maintain balance when it becomes unbalanced while driving and prevents the vehicle from tipping over.

In the past, this type of single-wheel non-invertable vehicle has been provided. However, the conventional wheelbarrows of this type were of the so-called "Yajirobee style" that ran on strings or strings, so the weight for balance was always located at the point of contact with the strings or strings of the unicycle. It was placed further down than the Therefore, in the case of conventional non-invertible wheels,
Because this weight was an obstacle, it was not possible to run on a flat surface.

Another example of a conventional non-invertible wheel is one in which the rotation axis of the inertial wheel is set vertically and the inertial wheel is rotated just like a top, thereby stabilizing it with the self-sustaining function of a top. be. However, in this example, when the rotational force of the inertial wheel begins to decline, a sweeping motion, or what is commonly called a "spinning motion," occurs, which makes it rather unstable and easily falls over. Furthermore, since the inertial wheel rotates horizontally, it is impossible to use it as a unicycle that runs on a flat surface.

In addition to the running wheels, the present invention is equipped with an inertia wheel that rotates parallel to the running wheels, so that when an imbalance occurs during running, the vehicle is automatically steered to maintain balance, thereby preventing the vehicle from collapsing. This article relates to a non-twin-wheeled vehicle that can be driven without any friction.

The present invention will be explained below based on embodiment figures.

In Figures 1 to 3, numeral 1 is a doll, 2 is a pair of left and right j
It is a downward U-shaped pedestal equipped with IiIII14, and I! on the left and right sides of this pedestal 2. 114 between these il&1
A horizontal running wheel axle I rotatably supported by 114
A driving running wheel 3 having B is provided.

This running wheel 3 is hollow with covers sb attached to both left and right sides of the ring. However, the running wheel axle 15
is provided at the center of the outer surface of each of the covers 31, is composed of a tube shaft, and is integrally provided with a gear 4 at one end.

Further, an inertial wheel 9 whose center shaft 16 is supported by the running wheel shaft 15 is provided inside the running wheel.

A pinion 6 is integrally provided at one end of the central shaft 16 of this inertial wheel, that is, a portion of the running wheel shaft 15 that projects outward from the center of the gear 4.
It meshes with a gear arm supported on one leg 14 of the frame by a horizontal shaft 1f.

However, a pinion 6 is integrally formed on the lever gear 7, and the pinion 6 meshes with the gear 4 of the running wheel shaft 15. Therefore, when the running wheel 3 is rotated by rubbing it on the floor surface, the inertial wheel 9 is rotated at an increased speed according to the gear ratio of the speed increasing gear mechanism.

In addition, tM! 8 is attached, and this is not only to maintain left and right balance, but also to raise the doll forward, which would otherwise fall backwards due to inertia during running.This allows the doll to repeatedly rock back and forth as it runs. do.

The first embodiment shown in FIGS. 1 to 3 shows the case where the axis of the running wheel shaft 111 and the axis of the inertial axle 16 coincide with each other. wheel set IB
1 shows an embodiment of the invention in which the inertia axles 16 and 16 are arranged parallel to each other.

In the same figure, the rotating shaft 16 of the inertial table 9 is a tubular sleeve shaft, and has a pincushion ring formed on the outer periphery of the part protruding from the outer surface of the inertial wheel, and a pincushion ring is formed on the outer periphery of the part protruding from the inner surface of the inertial wheel. A pinion 5 is formed on the outer periphery, and is rotatably supported by a support shaft i1% provided on one leg of the pedestal. The running wheel 3 is composed of a disc, and its axis 1! s
is supported by both legs 14 of the frame, and a gear 4 formed at one end of a running wheel shaft 15 is meshed with the binion 5 of the inertial wheel.

In the embodiment, when the inertia wheel is driven by pulling the thread wound around the bobbin wheel, the running wheel is rotated at a reduced speed. Conversely, when the running wheels 5 are driven, the inertial wheel 9 is rotated at an increased speed.

FIG. 6 and the off-line diagram show another embodiment of the present invention arranged concentrically with each other, but the inertial wheels 9 are arranged outside the pedestal 111114 as in the second embodiment. In other words, the central tube shaft 15, which is integral with the running wheel 3 and the disk, is supported by the pedestal leg U, and the other end of the pinion shaft U has a pinion b at one end inserted into the tube shaft length. An inertial wheel 9 is integrally attached, and the power transmission pinion and gear mechanism have the same structure as in the ii embodiment.

FIG. 8 shows an embodiment of the present invention '6: applied to a six-wheeled vehicle 1s. In the figure, U is a handle shaft that is rotatably attached to the seven frames of the two-wheeled vehicle, and the story is about the rear wheel of the two-wheeled vehicle. The lower end of the handle shaft H is rotatably attached to the upper side portion 148 of the frame 2 of the non-invertable steering vehicle of the present invention.

In the case of the non-invertable steering vehicle of the present invention shown in FIGS. 112 and 3, as is clear from the cross-sectional view in FIG. Since it can be stored in a compact size, it can be assembled into a compact structure.

Next, the operation of the non-invertible steering vehicle of the present invention will be explained by taking the embodiment shown in FIG. 1 as an example.

When the pedestal 2 is held by hand and the running wheels 3 are forcibly rotated by rubbing them against a suitable flat surface such as the floor, and then placed on the floor, the running wheels run. As the running wheel rotates, the gear number of the running wheel shaft J rotates, and this rotational force is increased in speed by the speed increasing gear mechanism of the binion 6, gearf, and binion 5, and is transmitted to the binion shaft 16, which is integrally formed on the left side. The inertia wheel is rotated at increased speed. By increasing the speed of the inertia vehicle, the running wheels are given self-sustaining force and run, but if the wheels are tilted due to slight irregularities on the floor, the wheels turn in the direction of the tilt, recover, and continue running. continue. Therefore, if the left and right balance is lost while driving, the vehicle will automatically steer itself to right itself and travel without falling over.

Also, since the energy generated by the initial forced rotation of the running wheels is stored in the inertial wheel, it is possible to travel a much greater distance than without an inertial wheel. In addition, doll 1
The frame 2, which is fixed to the connecting portion 1f of the leg 14, travels while repeating a slight rocking motion back and forth around the traveling wheel shaft 1fi due to the weight. This rocking motion gives the appearance that the doll 1 is pedaling the running wheels 3 with its feet, and has the effect of making the doll even more interesting as a toy.

2j from Figure 4 to Off Figure! In the fifth embodiment, in addition to strongly rubbing the running wheel 3 against a flat surface such as the floor, there is also a method of energizing the inertial wheel 9 by strongly pulling the thread on the bobbin winder. As mentioned above.

In the embodiment shown in FIG. 1, the weight 8 is required to always restore the doll 1, the pedestal B, etc. to an upright state, but in the embodiment shown in FIG. Since the movement of the pedestal 2 along the axis is prevented by the rear wheel recognition of the wheel cart 13, the weight a is not necessary. However, the i4 of the two-wheeled vehicle
Weights are provided as needed to balance the sides.

The steering wheel of the present invention can be used not only as a toy but also as a sports tool, for example, for practicing wheel riding.
