Abstract
The in-line roller blade can skate forward, backward, sideward, turn right, turn left and spin to serve as a figure skate. The in-line roller blade figure skate and skateboard comprise a composite belt enwraping around the wheels. The composite belt comprises the resilient belt, string and beads. The self-propelling mechanism can rotate the wheel that the rider can skate without pushing against the ground. These two techniques can be applied to the ice skate to have the sideward skating capability.
Claims22
A skating apparatus comprising a plurality of wheels and a composite belt,
- said composite belt being flexible and compressible,
- said plurality of wheels being rotatably mounted on said skating apparatus in-line,
- a slot surrounding a peripheral of each of said plurality of wheels,
- said composite belt comprising a resilient belt and a plurality of beads, said resilient belt fitting inside said slot, said plurality of beads being embedded in said resilient belt,
- each of said beads comprising a bracket and a skating means, said bracket fitting with said slot and pressing against said resilient belt, said skating means being mounted on said bracket,
- said resilient belt serving to absorb shock, to adjust the height of belt to increase contacts with ground and to adjust track curvature of said composite belt in turning direction to turn left and right wherein said composite belt further comprising strings, said strings passing through said bracket of each of said beads to hook-up said beads to be a chain.
A skating apparatus comprising a frame, a self-propelling means and a skating means,
- said self-propelling means comprising a pedal, a plurality of links and a wheel,
- said wheel being mounted on said frame with an axle,
- an up-and-down motion of said pedal driving said plurality of links to rotate said wheel to skate,
- said skating means being mounted at the bottom of said frame,
- said self-propelling means further comprising an engaging drum, a hub and a gripping means,
- said crankshaft having screws knotched on it,
- said engaging drum being rotatably mounted on the screws of said crankshaft,
- said hub being rotatably mounted inside said wheel,
- said gripping means biasing between said frame and said engaginging drum to grip said engaging drum with gripping force,
- said crankshaft driving said wheel to rotate with an engagement of said engaging drum and said hub wherein said skating means further comprises a plurality of rollers, said rollers being rotatably mounted on said frame to provide transverse motion for said skating apparatus.
A skating apparatus comprising a constant tension mechanism, a frame, a plurality of wheels and a belt,
- said plurality of wheels being rotatably mounted on said frame,
- said belt surrounding said wheels;
- said constant tension mechanism comprising an adjusting screw, a biasing spring and a sliding guide,
- a pair of holes knotched on said sliding guide;
- a pair of sliding slots being knotched on said frame;
- said plurality of wheels being mounted on a plurality of axles, one of said axles passing through said holes on said sliding guide and sliding inside said sliding slots:
- said adjusting screw being threaded on said frame, said biasing spring mounted on said adjusting screw to bias against said sliding guide;
- said biasing spring biasing against said sliding guide to maintain the constant tension in said belt;
- adjusting said adjusting screw to adjust said constant tension in said belt.
