Document Type and Number:
WIPO Patent Application WO/2010/087542
Kind Code:
A1
Abstract:
The present invention relates to a wheel which transforms according to the rotating direction of a drive shaft. Preferably, in places where the ground surface is flat, the drive shaft rotates forward and arc-shaped wheels integrally formed on plural driven shafts that are engaged with the drive shaft come together and overlap each other so that the wheel rotates as a circular rotating body, and in places where the ground surface is steep like a slope or stairs, the drive shaft rotates in reverse and the arc-shaped wheels integrally formed in the plural driven shafts that are engaged with the drive shaft open outwardly so that the wheel rotates with the vanes thereof extended. The wheel comprises the drive shaft (20) which rotates forward and in reverse by being connected to a rotary shaft (10) driven with a motor and the plural driven shafts (30) with the integrated arc-shaped wheels (32) that are engaged with the exterior of the drive shaft (20) so that the wheel shape is transformed when the driven shafts rotate forward or in reverse according to the rotating direction of the drive shaft.
