Smoothly steerable roller skate

Abstract

A steerable roller skate includes: a sole member of a roller skate having a pair of rear wheels transversely rotatably secured to a rear bottom portion of the sole member, a steering base steerably secured on a front bottom portion of the sole member, a pair of front wheels transversely rotatably secured on the steering base, a first magnet secured on a central bottom portion of the sole member, a second magnet secured on the steering base adjacent to the first magnet having opposite magnetic polarities of the first and second magnets for normally attracting the second magnet to the first magnet, and a non-magnetic spacer either formed on a bottom surface of the first magnet, or formed on an upper surface of the second magnet for spacing or separating the two magnets for smoothly steering the roller skate.

1 . A steerable roller skate comprising:
 a sole member having a longitudinal axis defined at a central portion thereof and having a pair of rear wheels transversely rotatably secured to a rear bottom portion of said sole member, a steering means having a steering base steerably secured to a front bottom portion of said sole member, a pair of front wheels transversely rotatably secured to the steering base of said steering means by a front axle, a first magnet secured to a central bottom portion of said sole member, a second magnet secured on said steering base normally positioned under said first magnet, said first and second magnets having opposite magnetic polarities thereof for a mutual magnetic attraction between said first and second magnets for normally restoring the steering base and the front wheels to allow said front axle to be projectively perpendicular to said longitudinal axis of said sole member for a normal straightforward skating of said roller skate; and a non-magnetic spacer either formed on a bottom surface of said first magnet, or formed on an upper surface of said second magnet to help separation of said first magnet from said second magnet as spaced by said non-magnetic spacer.   
     
     
         2 . A steerable roller skate according to  claim 1 , wherein said non-magnetic spacer is made of non-magnetic materials, and formed, secured, bonded, or welded on a surface of one said magnet to be spaced or separated from the other said magnet. 
     
     
         3 . A roller skate according to  claim 1 , wherein said non-magnetic spacer includes a plurality of stainless steel balls circularly formed on a bottom surface of said first magnet, or formed on an upper surface of said second magnet. 
     
     
         4 . A roller skate according to  claim 1 , wherein said non-magnetic spacer is a non-magnetic ring circularly formed on a surface of one said magnet to be spaced and separated from the other said magnet. 
     
     
         5 . A roller skate according to  claim 1 , wherein each said magnet is formed as a circular magnet.
