Three-wheeled skateboard method

Abstract

A method for propelling a skateboard. The method includes applying an alternating lateral force to first and second sides of a first end of the skateboard. The skateboard first end is offset from a second end of the skateboard, and the first and second ends define a board plane. The skateboard includes a truck assembly and a caster assembly. The caster assembly has a caster pin at an angle with respect to the board plane. Other embodiments are also disclosed.

1 . A method of propelling a skateboard, the method comprising:
 applying a lateral force to a first side of a board, the board further comprising a first end and a second end, the first end offset from the second end, and the second end defining a board plane, a truck assembly attached near the second end, the truck assembly including a shaft substantially perpendicular with the board, the shaft connecting to a truck axle supporting a first wheel and a second wheel, each of the first wheel and second wheel being freely rotatable about the truck axle, and a caster assembly attached near the first end of the board with a caster pin defining a fixed caster pin angle with respect to the board plane, the fixed caster pin angle forming an acute angle with respect to the board plane, the caster assembly including a caster fork supporting a caster wheel freely rotatable about a caster axle, such that the caster fork translates radially about the caster pin;   transferring a force through the caster assembly;   applying the transferred force to a surface, wherein the applied force is the product of the transferred force and the distance between a line perpendicular to the board plane and the caster axle; and   applying a lateral force to a second side of the board based on the application of the lateral force to the first side of the board.   
     
     
         2 . The method of  claim 1  further comprising adjusting the fixed caster pin angle relative to the board plane. 
     
     
         3 . The method of  claim 2  further comprising relocating an angle pin, wherein the caster pin is adjustable via alternate settings of the angle pin to obtain certain fixed angular positions that are angular with respect to the board plane. 
     
     
         4 . The method of  claim 2  further comprising adjusting the fixed caster pin angle relative to the board plane by configuring a caster block and lock nut arrangement to provide a desired fixed caster pin angle.
