Description

[Detailed description of the invention] The present invention relates to a foot pedal type self-propelled two-wheeled vehicle.

Normal two-wheeled bicycles have wheels on the front and back and are very stable, so they are widely used as practical vehicles, but unicycles are difficult to operate, but they are quite enjoyable for leisure purposes. The present invention is basically similar to a unicycle, that is, it has two wheels on the same axis, so it has a high degree of instability, but it has excellent maneuverability that conventional unicycles do not have, such as the ability to change direction from side to side. The purpose is to provide a self-propelled two-wheeled vehicle primarily for leisure use that is fun and provides exercise while having fun. In other words, in the present invention, the shafts at both ends of the crank to which the pedals are attached are supported on a support frame, inserted into these shafts so as to rotate freely, and provided with a power panel on the outside that engages with the crankshaft. A clutch disc is interposed between the vehicle and the wheels, and a stock that operates the clutch disc is attached to the support frame so that it can be tilted freely.When driving straight, pressing the pedal causes the left and right wheels to rotate at the same time, and the stock is operated. By engaging and disengaging the clutch disc, power transmission to either the left or right wheel is released and the vehicle can turn.

Hereinafter, specific examples will be described based on FIGS. 1 to 3.

Two pedals 2, 2 are rotatably attached to the crank 1, and shaft portions 3 at both ends of the crank 1 are supported by left and right support frames 4, respectively.

A wheel 5 is rotatably inserted into and supported by the shaft portion 3, and on the same axis are clutch discs 6A, 6B, a power disc 7, a stock lever receiver 8, a suction disc 9, and a presser disc 1, respectively.
0 is interposed, and these are normally urged by a spring 11 so that the clutch discs 6A and 6B are brought into close contact with each other.

One clutch disk 6A is locked to the wheel side, and the other clutch disk 6B is locked to the power board 7. The power plate 7, the suction cup 9, and the presser plate 10 are respectively locked by locking pieces 12 provided on the shaft portion 3, and can rotate in the same manner as the crank 1 rotates and can also move in the same direction in the axial direction. They are engaged with each other. The support frame 4 has an operating stock 1 connected to the stock lever receiver 8 via a stock detachable lever 13.
4 is attached via a pin 15 so as to be freely tiltable left and right. The stock 14 extends upward and has a hand grip 1 at its tip.
7 are attached to the vehicle, and the operator runs the foot pedal 2 while grasping the left and right hand grips 17.

Note that 18 indicates a cover for the wheel portion. Next, to explain the operation, in the state shown in FIG. 1, the operator puts both feet on the foot pedals 2, 2, grasps the left and right hand grips 17 with both hands, and pedals the pedals 2 in the same manner as a bicycle.

At this time, when the operating stock 14 is supported so as to be pushed outward on both sides, since the clutch discs 6A and 6B are pressed together by the springs 11, the rotation of the crank 1 is transferred from the shaft portion 3 to the power disc 7, the clutch disc 6A, and the clutch disc 6A, 6B. It is transmitted to the wheels 5 via 6B, and both wheels 5 are driven in the same way, so the vehicle travels straight.

On the other hand, as shown in FIG. 3, for example, when you pedal 2 while tilting one stock 14 inward, the stock lever receiver 8 moves outward via the detachable lever 13, and as a result, The power disc 7 and the clutch disc 6A integrally move outward while compressing the spring 11, thereby canceling the transmission of rotation to the wheel 5 on the saw side.

Therefore, the driving force from the crank 1 is transmitted only to the other wheel 5, and in this way, the direction of travel can be changed freely.

In this way, according to the present invention, it is possible to freely run in a straight direction and turn left and right, making it relatively easier than a conventional unicycle, but requiring more operating skills than a normal two-wheeled vehicle. Anyone can enjoy driving it, even though it is required.
