Abstract
A system and method for a skateboard and for propelling the skateboard. The skateboard system includes a board including a first end and a second end, the first end offset from the second end, and the second end defining a board plane. The skateboard system also includes a truck assembly attached near the first end of the board, and a caster assembly attached near the second end of the board. The caster assembly has a caster pin at an angle with respect to the board plane. Other embodiments are also disclosed.
Claims10
A skateboard comprising:
- a board including 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 first end, the truck assembly including a shaft substantially perpendicular with the board plane, the shaft connecting to an axle supporting a first wheel and a second wheel, each of the first wheel and second wheel being freely rotatable about the axle;
- and
- a caster assembly attached near the second end with a caster pin defining an adjustable caster pin angle with respect to the board plane wherein the caster pin is adjustably coupled relative to the board plane such that the predetermined caster pin angle is adjustable between forming a first acute angle with respect to the board plane and a substantially perpendicular angle with respect to the board plane, the caster assembly including a hemispherical caster base arrangement having caster assembly teeth for sliding engagement of the caster assembly, the caster assembly including a caster fork supporting a caster wheel freely rotatable about a caster axle, wherein the caster fork translates radially about the caster pin regardless of a selected caster pin angle.

A skateboard comprising:
- a board including 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 first end, the truck assembly including a reverse kingpin substantially perpendicular with the board plane, the reverse kingpin connecting to an axle supporting a first wheel and a second wheel, each of the first wheel and second wheel being freely rotatable about the axle;
- and
- a caster assembly attached near the second end with a caster kingpin defining an adjustable caster pin angle with respect to the board plane wherein the caster kingpin is adjustably coupled relative to the board plane such that the caster kingpin angle is adjustable between forming a first acute angle with respect to the board plane and a substantially perpendicular angle with respect to the board plane, the caster kingpin having a caster block and lock nut arranged to secure a caster lock plate to hold caster kingpin at a selected caster kingpin angle, the caster assembly including a hemispherical caster base arrangement having caster assembly teeth for sliding engagement of the caster assembly, the caster assembly including a caster fork supporting a caster wheel freely rotatable about a caster axle, wherein the caster fork translates radially about the caster kingpin regardless of the selected caster kingpin angle.
