Abstract

A moving wheel platform that minimizes wheel interactions with noncontinuous and uneven surfaces. The platform provides rotation-inhibiting structures onto or into the moving wheel platforms that aids with eliminating wheel bite.

First claim

What is claimed is:

1. A truck comprising:
a hanger; the hanger comprising:
a cylindrical body; wherein the cylindrical body surrounds a bore or void;
a pivot saddle; the pivot saddle further comprises a pivot tip and a pivot body surrounding an aperture;
at least two rotation inhibiting structures;

an axle; wherein the axle is received within the bore or the void of the cylindrical body of the hanger;
an assembly; the assembly comprising:
a first arm and a second arm;
a first auxiliary wheel and a second auxiliary wheel;
wherein:
the first and second arms comprises a front region, a middle region, and a rear region;
the front region forms a front aperture;
the middle region forms a middle aperture;
the rear region forms a rear aperture;
the two rotation inhibiting structures are adjacent and on opposing sides to the pivot body and spaced from the cylindrical body; and
the two rotation inhibiting structures are coplanar to each other and wherein the middle region of the first and second arms are complimentary and located between the rotation inhibiting structure and the cylindrical body.

2. The truck of claim 1 , wherein the first arm and the second arm comprises a first end and a second end, and wherein the first end and the second end are substantially planar to one another.

3. The truck of claim 2 , wherein the first end of the first and second arms are shorter in length than the second end of the first and second arms.

4. The truck of claim 1 , wherein the first arm and the second arm comprises a first end and a second end, and wherein the first end and the second end are at an angle between 178 degrees and 180 degrees.

5. The truck of claim 4 , wherein the truck is in a reverse king pin configuration.

6. The truck of claim 1 , wherein the truck is in a nose of a skateboard.

7. The truck of claim 6 , wherein the truck is in a tail of a skateboard.

8. The truck of claim 1 , wherein a third wheel and a fourth wheel are coupled to the axle.

9. The truck of claim 8 , wherein the first auxiliary wheel, the second auxiliary wheel, the third wheel, and the fourth wheel are the same diameter.

10. The truck of claim 8 , wherein the first auxiliary wheel, the second auxiliary wheel, the third wheel, and the fourth wheel each comprise a diameter, and wherein each diameter of the first auxiliary wheel, the second auxiliary wheel, the third wheel, and the fourth wheel is between 2.7 and 4 inches.

11. The truck of claim 8 , wherein the first auxiliary wheel, the second auxiliary wheel, the third wheel and the fourth wheel are in a diamond-shape configuration.

12. The truck of claim 1 , wherein the rotation-inhibiting structure defines a predetermined rotational range of movement for the first arm and the second arm.

13. The truck of claim 12 , wherein the predetermined rotational range of movement is between 0 degrees and 35 degrees.

14. The truck of claim 1 , wherein a length of the rotation inhibiting structure is non-circular nor elliptical with a length between 2 to 2.5 inches.

15. The truck of claim 14 , wherein a width of the rotation inhibiting structure is between 0.125 inch and 0.375 inch.

16. The truck of claim 1 , wherein the truck further comprises one or more flange bearings that are housed within the middle aperture of the first and second arms to reduce frictional forces between the cylindrical body of the hanger and the first and second arms.

17. The truck of claim 16 , wherein the one or more flange bearings are comprised of a nylon material.

18. The truck of claim 1 , wherein the front aperture, the middle aperture, and the rear aperture are circular.

19. The truck of claim 1 , wherein the rotation-inhibiting structure is solid.

20. The truck of claim 1 , wherein the rotation-inhibiting structure is hollow.
