Title:
SPRING BIASING FORCE FOR CONVERTING GRAVITY GOING DOWN TO GROUND TO PARALLEL PROPULSION FORCE
Document Type and Number:
Japanese Patent JP2022017146
Kind Code:
A
Abstract:
To convert, with an elastic spring, the gravity allowing driving force vertically acting on the ground to propulsion force of a traveling vehicle.SOLUTION: A tip portion of a heavy scraping rod, the weight of which is 30 kg is placed on a portion of a center wheel of a towed dolly at a major portion of a fan mounted on the towed dolly as a base of a spring biasing force and opening/closing in a fan shape, and the other end portion of the scraping rod is placed with an angle of about 45° held with respect to the dolly. The scraping rod is brought into collision with a rubber elastic round body having a diameter of 25 cm and fixed to be attached to the dolly side, and thus propulsion force of the entire traveling body is generated.SELECTED DRAWING: Figure 1
