Skate wheel for manual skating apparatus

Abstract

A skate wheel for manual skating apparatus includes a structural body, an outer cover and an inner cover. The structural body is formed in an annular shape and has an outer annular surface and an inner annular surface. The outer annular surface has a plurality of ridges formed thereon. The outer cover is coupled on the outer annular surface to cover the ridges and the inner cover is held on the inner annular surface for covering thereof. Through the uneven surface formed by the ridges, separation of the outer cover can be prevented. A structure with a harder inner side and softer outer side also can be formed. When this structure is used for skate wheels of a manual skating apparatus, durability increases and shock absorption effect enhances, thus can provide longer lifespan and improved comfort, and protect users to meet use requirements.

What is claimed is: 
     
         1 . A skate wheel for manual skating apparatus, comprising:
 a structural body which is formed in an annular shape and includes an outer annular surface and an inner annular surface, the outer annular surface including a plurality of ridges formed thereon;   an outer cover coupled on the outer annular surface to cover the ridges; and   an inner cover held on the inner annular surface for covering thereof.   
     
     
         2 . The skate wheel of  claim 1 , wherein the ridges are arranged annularly on the outer annular surface. 
     
     
         3 . The skate wheel of  claim 2 , wherein the ridges are arranged in two rows at a front side and a rear side in a dislocated manner. 
     
     
         4 . The skate wheel of  claim 1 , wherein the inner annular surface is extended transversely to form an annular flange which includes at least one slot run through by the inner cover. 
     
     
         5 . The skate wheel of  claim 4 , wherein the annular flange includes at least five slots spaced evenly from each other. 
     
     
         6 . The skate wheel of  claim 1 , wherein the inner annular surface includes a plurality of recesses covered by the inner cover. 
     
     
         7 . The skate wheel of  claim 6 , wherein each of the recesses includes a wider shallow portion and a narrower deep portion. 
     
     
         8 . The skate wheel of  claim 1 , wherein each of the ridges includes a narrower upper side and a wider lower side.
