Claims
- 1. A caster wheel assembly comprising:
a caster fork; a caster wheel rotatably supported by the caster fork; a caster swivel post defining an axis about which the caster fork rotates, the caster swivel post being adapted to rotate about a pivot axis within a cylindrical housing.
- 2. The caster wheel assembly according to claim 1 further comprising an upper spline that is in fixed relation to the housing and a lower spline that is in a fixed relation to the caster fork, the lower spline being adapted to lock into engagement with the upper spline to fix the angular position of the caster swivel post with respect to the housing.
- 3. The caster wheel assembly according to claim 1 further comprising an angled wedge between the caster fork and the housing to retain the caster swivel post in a desired angular position.
- 4. The caster wheel assembly according to claim 1 further comprising setscrews that are threaded into the caster swivel post and bear against the housing to prevent the caster swivel post from pivoting.
- 5. The caster wheel assembly according to claim 1 wherein the caster swivel post rotates about an axis perpendicular to the caster swivel post.
- 6. The caster wheel assembly according to claim 1 further comprising mating surfaces that lock together under the tension in order to fix the angle of the caster swivel post with respect to the housing.
- 7. A wheel assembly comprising:
a housing; an axle supported by to the housing and which in turn rotatably supports a wheel, the axle being adapted to rotate about a pivot axis within a cylindrical housing.
- 8. The wheel assembly according to claim 7 further comprising an inner spline that is in fixed relation to the housing and an outer lower spline that is adapted to lock into engagement with the inner spline to fix the angular position of the axle with respect to the housing.
- 9. The wheel assembly according to claim 7 further comprising an angled wedge between the wheel and the housing to retain the axle in a desired angular position.
- 10. The wheel assembly according to claim 7 further comprising setscrews that are threaded into the axle and bear against the housing to prevent the axle from pivoting.
- 11. The wheel assembly according to claim 7 wherein the axle rotates about an axis perpendicular to the axle.
- 12. The wheel assembly according to claim 7 further comprising mating surfaces that lock together under the tension in order to fix the angle of the axle with respect to the housing.
