A skateboard apparatus wherein a torsion bar containing an inner pipe, outer pipes and flexible, rubber inserts therebetween assist the user in determining the direction and speed of the skateboard. The torsion bar is connected to platforms on which the user places his feet, and the underside of said platforms contain casters which enable the skateboard and its user to move in linear or non-linear directions as desired with just one initial push from the ground.
1. A skateboard comprising:
(a) a front rotatable platform and a rear rotatable platform;
(b) a torsion bar means attached to the front and rear platforms, said torsion bar comprising a plurality of outer pipes capable of rotating in proportion to the rotation of either or both platforms, an inner pipe, and a plurality of flexible insert means connecting said inner pipe to said outer pipes whereby said flexible insert means twists in proportion to the rotation of said outer pipes; and
(c) caster means attached to an underside of the front and rear platforms for permitting the skateboard to be placed in motion by a user.
2. The skateboard of claim 1 wherein the inner pipe contained within the torsion bar does not rotate when an outer pipe of said torsion bar rotates.
3. The skateboard of claim 1 further comprising a means within each platform into which an end of the torsion bar may fit.
4. The skateboard of claim 1 further comprising nub and groove means in said outer pipes to secure the flexible insert means to said outer pipes.
5. The skateboard of claim 1 further comprising nub and groove means in said inner pipe to secure the flexible insert means to said inner pipe.
6. The skateboard of claim 1 wherein the outer pipes further comprise a folding means to secure the flexible insert means to said outer pipes.
7. The skateboard of claim 1 further comprising a board means for attaching each outer pipe to its respective platform.
8. The skateboard of claim 1 further comprising a means to clamp each outer pipe to its respective platform.
9. The skateboard of claim 4 wherein the inner pipe of the torsion bar does not rotate.
10. The skateboard of claim 9 further comprising nub and groove means in said inner pipe to secure the flexible insert means to said inner pipe.
