Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light vehicle that operates by using walking itself as a power source.

[0002]

2. Description of the Related Art Conventionally, this type of vehicle has a wheelbarrow, but the use position is different when walking and when resting.
This is inconvenient, but it is valuable for walking.

[0003]

[Problems to be Solved by the Invention] Conventionally used walking tools are pine needles, wheelchairs, etc., but it may be possible to have an auxiliary walking tool outside.

According to the present invention, it is desired to provide a walking vehicle equipped with a handle and a saddle so that it can walk on its own. This idea was motivated and born.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a saddle attached to a walking vehicle, and the weight of the walking is entrusted to the saddle to make the walking lighter, and a steering wheel is attached to drive the vehicle. It aims to provide a human-powered pedestrian that is fully functional and can perform free action without the need for human assistance.

Therefore, since it is a pedestrian, the vehicle body is made vertical and is grouped forward in order to widen the range of motion of the feet, the left and right rear legs avoid the lower tier, and both sides of the saddle, that is, boarding, from the top of the vehicle body. The person tries to achieve the purpose by the above steps, which circulates the user's waist to reach the rear and connects to the rear wheel directly below.

Further, it is necessary to secure a changing device for adjusting the height of the saddle according to the difference in height.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, the elevation angle of the handle main shaft 2 is set to 15 degrees, so that the vehicle body 4 is made of a rectangular plate-shaped light alloy according to the angle.

The purpose of making the vehicle body 4 rectangular and vertical is a selection measure for widening the pace required for walking, and
There is also an advantage that the ride from the rear is easy.

Further, the rear leg and the vehicle body connecting portion 7 are provided on the uppermost portion of the vehicle body 4, and the process in which the left and right rear legs 5 and 6 reach the rear wheel while guarding both sides of the occupant with this as a base, The effect is great because it embraces the passengers in the center.

FIG. 2 is an explanatory view of the vertical movement device of the saddle.

There are two scenes to be introduced by referring to this figure. One is that the saddle posture does not change and the vertical movement, and the other is that the position of the quick lever moves back and forth between the upper and lower sides of the connecting support shaft 9. Is.

This function is to easily move the saddle 8 up and down, and it is a mechanism that can be quickly changed up and down by the operation of tightening and loosening the quick lever 11. The reason why the posture of the saddle does not change during the vertical movement is that the seat post 21 connecting the two upper and lower connecting support shafts 9 is slightly moved forward and backward, which is the effect of the double connection 9. .

FIG. 3 is a diagram showing a connecting process of the vehicle body and the right rear leg. By using a combination drop plug 16 of the vehicle body and the rear leg, the rear leg can be opened and closed and easily disassembled. It is also useful for storage, and the left rear leg is the same as the right rear leg.

FIG. 4 is a sectional view of the quick lever, in which the axis of the quick lever 11 passes through the disk from the right and then passes between the upper and lower sides of the connecting support shaft 9 for the vehicle body and the seat post. Rotatably through the connecting hole, and again passes between the upper and lower sides of the connecting support shaft 9 to be screwed on the left disk, and the vertical movement of the saddle 8 is determined by tightening and loosening the quick lever.
