Roller shoes

Abstract

As described above, the roller shoes of the present invention have the following structures and functions: the two roller-grooves are at the front and back side of the undersurface of the base of the shoe; the rollers are affixed to the roller-grooves; the roller-shafts of the roller and the roller-shaft supporting grooves are linked by magnetic force so that the roller-shafts of the roller do not separate from the roller-shaft supporting grooves. Because these two rollers are fixed at the front and back side of the base of the shoe, the user can use them like roller skates. And, if he wants use them like usual shoes after using them as roller skates, he can shift their usage from the roller-shoes to common shoes by easily separating the rollers from the roller-grooves.

What is claimed is:  
     
         1 . Roller shoes, including: 
 roller-grooves on the undersurface of the shoes' base pieces;    roller-shaft supporting plates, which have semicircular openings at both left and right lower sides, fixed at the roller-grooves; and    removable rollers, which have outward protruding roller-shafts, and which are insertable into the roller-shaft supporting grooves,    wherein the roller-grooves are located on the front and back sides of the undersurface of the each base pieces;    wherein magnet-grooves are located at the both edges of the roller-shafts and magnets are inserted in the magnet-grooves; and    wherein the roller-shaft supporting grooves are made of metal.    
     
     
         2 . Roller shoes in accordance with  claim 1 , wherein the roller-shaft supporting plates are made of metal.  
     
     
         3 . Roller shoes, including: 
 roller-grooves on the undersurface of the shoes' base pieces;    roller-shaft supporting plates, which have semicircular openings at both left and right lower sides, fixed at the roller-grooves; and    removable rollers, which have outward protruding roller-shafts, and which are insertable into the roller-shaft supporting grooves,    wherein the roller-grooves are located on the front and back sides of the undersurface of the each base pieces;    wherein the roller-shafts are made of metal; and    wherein the roller-shaft supporting grooves are made of magnets.
