Abstract
A swivel wheel assembly includes a wheel axle, and a vehicle wheel rotatably mounted on the wheel axle. A shock-absorbing wheel fork is secured to opposite ends of the wheel axle and includes first and second elongated spaced-apart support arms. A pivot pin extends through pin openings formed with proximal ends of the first and second support arms. A base is carried by the pivot pin, and is adapted for pivoting movement about an axis defined by the pivot pin. An adjustable shock absorber dampens pivoting movement of the base relative to the vehicle wheel, thereby absorbing the energy of sudden shocks to the vehicle wheel during use.
