Abstract

A skateboard with steering wheel for steering control, the body of which having two opposite holes at the front biased inward from a transverse line through 4-5 angle for fastening two front wheels by two wheel holders, and two ring-shaped members for fastening two rear wheels by two wheel hubs and a wheel axle. A steel tube is fastened in a tubular seat on the body of the skateboard and rotated by a steering wheel two turn the front wheels by a link for steering control.

Claims

1. A skateboard with steering wheel, comprising:

a body having a first pair of holes bilaterally disposed at one end in vertical direction, a second pair of holes and a pair of ring-shaped members transversely aligned at an opposite end, and a tubular seat vertically disposed at the middle in line with said first pair of holes, said tubular seat having a closed bottom edge, a first hole in longitudinal direction, a second hole in transverse direction;

a steel tube inserted into the first hole on said tubular seat, said steel tube having a first pivot hole at one end and a second pivot hole at an opposite end, said second pivot hole being secured to the second hole on said tubular seat by a screw and a locknut;

a bellows pipe sleeved on said steel tube;

a steering wheel mounted on said steel tube at the top, said steering wheel having a pivot hole at the bottom secured to the first pivot hole on said steel tube by a screw and a locknut;

a metal plate inserted inside said tubular seat stopped against said steel tube, said metal plate having toothed projections engaged in the top surface of the closed bottom edge of said tubular seat;

two wheel holders respectively mounted on said first pair of holes on said body, said wheel holders each having a hold fastened in either of said first pair of holes by a bolt and a locknut, a recessed hole at a suitable location, and an axle;

two front wheels respectively mounted on the axle of either of said wheel holders and secured in place by locknuts;

a link secured to said steel tube, said link having two opposite ends respectively engaged into the recessed hole on either of said wheel holders;

a wheel axle inserted through said pair of ring-shaped members and said second pair of holes on said body to hold two wheel hubs;

two rear wheels mounted on said wheel axle at two opposite ends and secured in place by locknuts; and

wherein said first pair of holes on said body are respectively biased inward from a transverse line through 4°

to 5°

angle so that said front wheels are protected from being caused to tilt outward.
