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:
an elongated body comprising a first end and a second end distal to the first end;
a void formed and surrounded by the elongated body at the first end;
a pivot saddle; the pivot saddle further comprises a pivot tip and a pivot body;

wherein the pivot body surrounds an aperture;
an axle coupled to the hanger and received within the void;
a central wheel affixed to the axle;
a single arm rotatably coupled to the elongated body, the arm comprising:
a front region forming a front aperture;
a middle region forming a middle aperture;
a rear region forming a rear aperture;
wherein the axle extends through the middle aperture of the single arm;
wherein the axle provides an axis of rotation for the single arm;

a front axle received by the front aperture;
a first front wheel and a second front wheel coupled to the front axle;
a rear axle received by the rear aperture;
a first rear wheel and a second rear wheel coupled to the rear axle.

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

4. The truck of claim 1 , wherein the truck is in a tail of a skateboard.

5. The truck of claim 1 , wherein the central wheel, the first front wheel, the second front wheel, the first rear wheel, and the second rear wheel comprise equal diameters.

6. The truck of claim 1 , wherein the elongated body forms a rotation inhibiting structure in the form of a notch; and wherein the single arm comprises a rotation inhibiting protrusion configured to be received within the notch of the rotation inhibiting structure.

7. The truck of claim 6 , wherein the rotation inhibiting structure defines a predetermined rotational range of movement for the arm.

8. The truck of claim 7 , wherein the predetermined rotational range of movement is between 0 degrees and 35 degrees.

9. The truck of claim 1 , wherein the truck further comprises one or more flange bearings that are housed within the middle aperture of the single arm to reduce frictional forces between the elongated body of the hanger and the single arm.

10. The truck of claim 9 , wherein the one or more flange bearings are comprised of a nylon material.

11. The truck of claim 1 , wherein the truck is in a reverse king pin configuration.

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

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

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

15. A truck comprising:
a hanger; the hanger comprising:
an elongated body comprising a first end and a second end distal to the first end;
a void formed and surrounded by the elongated body at the first end;
a pivot saddle; the pivot saddle further comprises a pivot tip and a pivot body;

wherein the pivot body surrounds an aperture;
an axle coupled to the hanger and received within the void;
a first central wheel affixed to the axle;
a single arm rotatably coupled to the elongated body, the arm comprising:
a front region forming a front aperture;
a middle region forming a middle aperture;
a rear region forming a rear aperture;
wherein the middle region is a two-segment region outlining a substantially rectangular shape;
wherein the axle extends through the middle aperture of the single arm;
wherein the axle provides an axis of rotation for the single arm;

a front axle received by the front aperture;
a first front wheel and a second front wheel coupled to the front axle;
a rear axle received by the rear aperture;
a single rear wheel coupled to the rear axle;
wherein the elongated body forms one or more rotation inhibiting structures in the form of a notch; and
wherein the arm comprises one or more rotation inhibiting protrusions configured to be received within the notch of the one or more rotation inhibiting structures.

16. The truck of claim 15 , wherein the hanger is configured to couple to a bottom surface of a skateboard deck.

17. The truck of claim 16 , wherein the rotation inhibiting structure prevents any of the first front wheel, the second front wheel, and the single rear wheel from contacting the bottom surface of the skateboard deck.

18. The truck of claim 15 , wherein the rotation inhibiting structure defines a predetermined rotational range of movement for the arm.

19. The truck of claim 18 , wherein the predetermined rotational range of movement is between 0 degrees and 35 degrees.

20. The truck of claim 15 , further comprising a second central wheel affixed to the axle.
