摘要:
A roller ski gear (300) wherein elastic wheels (302) are rotatably mounted on the front and rear portions of a boot resting plate (301), the elastic wheels each having a wheel supporting means having a circular rim portion formed on the outer periphery thereof and a tire portion mounted on a circular rim portion of the wheel supporting means and capable of being deformed in a direction normal to the running direction of the wheel. In the elastic wheel (302), it is possible to easily change the running direction with the axles of the wheels being maintained in the same direction, and by making use of this characteristic it is possible to operate the roller ski gear in the same way as operating a snow ski.
摘要:
A composite wheel device wherein a plurality of auxiliary wheels (31) supported rotatably about axes in directions identical with tangent lines of a circular rim portion (12) of a wheel are provided on the circular rim portion so as to form a tire (40), and rotation of the tire and rotations of the auxiliary wheels are combined together so as to make the wheel run in a desirable direction.
