Roller board

Abstract

A roller board including a board and two or more downwardly-disposed roller assemblies mounted on the board. Each roller assembly has an annular retaining collar with a spherical recess, a plurality of bearings seated within the recess, and a spherical roller ball rotatably seated in the recess in contact with the bearings. A stabilizer assembly is mounted between the roller assemblies to give lateral stability, and a false axle is provided in each of the roller assemblies for imparting increased friction upon contact with the roller ball. The false axle imparts a higher coefficient of friction on hard cornering, thereby simulating “carving” or digging in the edges of a snow board. The foregoing features combine to exactly simulate the sensation of using a snow board on snow.

I claim:  
     
         1 . A roller board, comprising: 
 a board;    at least two downwardly-disposed roller assemblies mounted on said board, each roller assembly further comprising an annular retaining collar defining a spherical recess, a plurality of bearings seated within the recess, and a spherical roller ball rotatably seated in the recess of each of the retaining collars in contact with said plurality of bearings.    
     
     
         2 . The roller board according to    claim 1   , further comprising a stabilizer assembly mounted between the at least two roller assemblies, said stabilizers comprising a downwardly extending truck secured to said board and having a pair of wheels mounted thereon.  
     
     
         3 . The roller board according to    claim 1   , further comprising a false axle in each of said roller assemblies, said false axles including an axle snubber mounted within the spherical recess of the annular retaining collar for imparting increased friction upon contact with said roller ball.  
     
     
         4 . The roller board according to    claim 3   , wherein said false axles further include an adjustment screw and lock nut for adjusting the degree of friction imparted upon said roller ball.  
     
     
         5 . A roller board, comprising: 
 a board;    three downwardly-disposed roller assemblies mounted in-line on said board, each roller assembly further comprising an annular retaining collar defining a spherical recess, a plurality of bearings seated within the recess, and a spherical roller ball rotatably seated in the recess of each of the retaining collars in contact with said plurality of bearings.    
     
     
         6 . A roller board, comprising: 
 a board;    a pair of two downwardly-disposed tandem roller assemblies mounted on said board, each tandem roller assembly further comprising an annular retaining collar defining a pair of side-by-side spherical recesses, a plurality of bearings seated within each of said recesses, and a plurality of spherical roller balls each rotatably seated in a corresponding recess in said retaining collars in contact with said plurality of bearings.
