Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an improvement of a scooter type vehicle having a foot-operated brake device.

[0002]

2. Description of the Related Art Conventionally, a scooter is provided with a foot-operated brake device so that a brake pedal projects into a footrest space from a low-floor footrest that defines a lower end of the footrest space between a handle and a seat. Type vehicles exist. The above-mentioned scooter type vehicle has a substantially flat footrest surface on the upper surface of the footrest, and the driver usually places his / her feet on the footrest so that the entire sole is in close contact with the footrest surface. Run.
Therefore, when depressing the brake pedal, the driver lifts the leg so that the foot portion is completely separated from the footrest surface and depresses the brake pedal so that the sole of the foot contacts only the brake pedal, or Or, an operation method in which the heel of the foot is left on the footrest surface and the foot is lifted so that the sole of the foot is separated from the footrest surface, and the front portion of the foot is brought into contact with the brake pedal with the heel as a fulcrum to depress the brake pedal. Take.

[0003]

SUMMARY OF THE INVENTION The former operation method described above uses the ankle of the stepping leg as a fulcrum to rotate the foot to adjust the amount of depression of the brake pedal, or the hip joint of the stepping leg as a fulcrum. The amount of depression of the brake pedal is adjusted by rotating the entire stepping foot.However, when the ankle is used as the fulcrum, the fulcrum floats in the air, and the amount of depression becomes unstable, making fine adjustments possible. If the hip joint is used as a fulcrum, the fulcrum is too far from the brake pedal, so it is still difficult to adjust the amount of depression. Above all, it is difficult to bend the entire leg to adjust the amount of depression of the brake pedal. There is a problem that the thigh is heavily loaded and becomes very tired. In the latter operation method described above, since the heel of the foot is left on the footrest and the foot is bent with the heel as a fulcrum to adjust the depression amount of the brake pedal, the depression amount is larger than that of the former method. Stable and delicate adjustments can be made, but the footrest space of a scooter type vehicle is usually only wide enough for the driver to bend his knees to about 90 degrees and place his legs. In order to leave the sole behind the footrest surface and depress the brake pedal, the toes of the foot must be lifted so that the ankle bends sharply at a sharp angle, and that state must be maintained by itself. Since it has to be carried out, there is a problem that the lower leg and ankle of the leg are heavily burdened and are extremely worn. These problems become particularly problematic when the vehicle is used for business such as newspaper delivery where the vehicle is frequently stopped and started, and there is a strong demand for improvement in the market. As described above, the conventional scooter type vehicle with a foot-operated brake device has many problems to be improved in consideration of its operability.

[0004]

In order to solve the above-mentioned problems, a scooter type vehicle with a foot-operated brake device according to the present invention defines a lower end between a steering wheel and a seat by a footrest having a low floor. In a scooter-type vehicle having a footrest space, the footrest base is provided with a foot-operated brake device having a brake lever protruding toward the footrest space, the footrest base is provided with the brake lever. It is characterized in that a footrest capable of holding the foot of the driver's leg in a state immediately before stepping on is formed. The footrest is such that at least the heel of the foot of the driver's foot is left on the footrest, and the front part of the back of the foot is located on the upper surface of the brake pedal. Can be formed to hold. Further, preferably, the footrest is a plate-shaped footrest on which the heel of the foot of the driver's foot is placed, and is provided continuously in front of the footrest so that the footrest contacts the back surface of the foot. And a protrusion formed higher than the footrest may be integrally formed.
