Skate

Abstract

A skate includes a ring-shaped wheel rim ( 1 ), in inner side of which a ring-shaped track ( 5 ) is provided and extends along the circumferential direction of the wheel rim; a wheel carrier provided in the inner side of the wheel rim; rollers ( 41, 42 ) located on the wheel carrier and rolling on the ring-shaped track ( 5 ); a pedal ( 3 ) provided on the wheel carrier. So the skate with such structure can decrease the height of the pedal, and eliminate the limit that the diameter of the wheel rim cannot be increased because of the limit of torque effected on the feet. Therefore, the diameter of the wheel rim of the skate can be much larger than the diameter of the sliding wheel of the prior skate, and thus the skate has the stronger performance of crossing the vertical wall.

1 . A skate, comprising:
 a ring shaped wheel rim, on an inner side of which a ring-shaped track is provided and extends along a circumferential direction of the wheel rim;   a wheel carrier provided in the inner side of the wheel rim;   rollers located on the wheel carrier and rolling on the ring-shaped track; and   a pedal provided on the wheel carrier.   
     
     
         2 . The skate of  claim 1 , wherein the wheel carrier includes a ring-shaped part, on periphery of which the rollers are arranged. 
     
     
         3 . The skate of  claim 1 , wherein the wheel carrier at least comprises an upper part and a lower part connected with each other through a support, and both of the upper part and the lower part are provided with an arc part adapting the ring-shaped track respectively, wherein the rollers are arranged on the arc parts. 
     
     
         4 . The skate of  claim 1 , wherein the skate further comprises a foot blocking member including a blocking part for semi-enclosing the wheel rim and a connecting part connecting with the blocking part, and the connecting part is fastened on the wheel carrier. 
     
     
         5 . The skate of  claim 1 , wherein the rollers comprise vertical rollers axes of which are in parallel with that of the wheel rim. 
     
     
         6 . The skate of  claim 5 , wherein the rollers further comprise lateral rollers axes of which are perpendicular to that of the wheel rim. 
     
     
         7 . The skate of  claim 1 , wherein the wheel carrier is provided with a sub-wheel carrier that extends towards a rear direction of the wheel rim and is provided with sub-wheels. 
     
     
         8 . The skate of  claim 7 , wherein the wheel carrier has two sub-wheel carriers that are arranged on both sides of the wheel carrier respectively, wherein each of the two sub-wheel carriers is provided with a sub-wheel. 
     
     
         9 . The skate of  claim 7 , wherein the sub-wheels are tilting relative to the vertical direction. 
     
     
         10 . The skate of  claim 7 , wherein the wheel rim and the sub-wheels are provided with a tire or a rubber tape.
