| Abstract: |
The figure-blade roller skake costitutes the steering cushion mechanism. Due to the steering cushion mechanism, as the roller blade skate tilts, the wheels are aligned on an curved track. Shifting the body weight right, the steering cushion mechanism will cause the rollers to curve to the right; shifting the body weight left, the steering cushion mechanism will cause the rollers to the curve to the left. The brake wheel uses the clamping force to brake the skate to stop. The brake wheel can serve as both wheel and brake.

First Claim:
Show all 25 claims |
I claim:
1. A skating apparatus comprising a frame, a plurity of wheels and axles, and a resilient axle clamping support means,
- said wheels being rotatably mounted on said frame with said axles;
- said axles being supported by said resilient axle clamping support means,
- said frame comprising a seris of pairs of hole means inclined at different angles;
- said resilient axle clamping support means being mounted in said hole means on both sides of said frame, said resilient axle clamping support means holding said axles and providing resilient restoring forces to restore said axle to original position, said resilient restoring forces comprising longitudinal restoring force along an axis of said axle and transverse restoring force along an axis of said hole means;
- tilting said skating apparatus, said resilient axle clamping support means being distorted to adjust said axles to align said wheels to form a curved track to change the skating direction.
