  • Skateboard driven with both feet
    Patent number: 10905939
    Abstract: A conventional skateboard driven by swinging a board with both feet like a seesaw has a great number of parts, is complicated and becomes heavy. Therefore, a light traveling performance is deteriorated. Further, increase of the parts number adversely affects a manufacturing cost. The invention employs a mechanism which can drive in a swinging board with the least parts structure. Further, a shape of the board on which both feet are got is formed into a so-called inverse gull-wing shape, thereby suppressing a ground height of a boarding surface. Further, a flexible motion performance can be achieved at a corner by the provision of a steering mechanism.
