Skateboard with direction-caster
A skateboard having a front board, a rear board, a connecting element which interconnects the front board and the rear board in a spaced relationship, at least one direction-caster mounted on the underside of each of the front board and the rear board; and the connecting element comprises an elastic member so that the connecting element can be elastically twisted by application of at least one of a twisting or bending force and restores to its original shape when the force is removed.
1. A skateboard comprising:
a front board,
a rear board,
a connecting element which interconnects the front board and the rear board in a spaced relationship,
at least one direction-caster, that is freely movable about its pivot axis, mounted on the underside of each of the front board and the rear board so that the pivot axis of each is inclined at an acute angle with respect to the front and rear boards with a common orientation; and
wherein the connecting element comprises an elastic member so that the connecting element can be moved by application of at least one of a twisting or bending force and elastically restores to its original shape when the force is removed.
2. A skateboard according to claim 1 , wherein the front board has at least one direction-caster and the rear board has at least one fixed roller set.
3. A skateboard according to claim 1 , wherein the connecting element is a twist-pipe having an elastic matter therein.
4. A skateboard according to claim 1 , wherein the connecting element comprises:
a twist-pipe and two elastic members connected at their one ends to the front board and at their other ends to the rear board, wherein the two elastic members are arranged substantially parallel to each other.
5. The skateboard of claim 1 wherein the at least one direction-caster comprises a skate blade.
6. A skateboard according to claim 1 wherein the at least one direction-caster comprises at least one wheel.
7. A skateboard according to claim 1 , wherein the connecting element comprises:
a twist-pipe and two elastic members connected at their one ends to the front board and at their other ends to the rear board, and wherein the twist pipe lies between the two elastic members.
8. A skateboard according to claim 7 , wherein the twist-pipe and two elastic members are substantially parallel to each other.
9. A skateboard according to claim 1 , wherein the direction-caster comprises:
a wheel support attached to the board having the shape of a wedge,
a roller arm pivotably connected to the wheel support, and
a roller rotatably connected to a free-end part of the roller arm.
10. A skateboard comprising:
a front board,
a rear board,
a connecting element which interconnects the front board and the rear board in a spaced relationship,
at least one direction-caster mounted on the underside of each of the front board and the rear board and oriented forward at an acute angle defined by inclination of a pivot axis of the at least one direction caster relative to at least one of the first board or second board; and
wherein the connecting element comprises a twist element which can be freely twisted by application of twisting force.
11. A skateboard according to claim 10 , wherein the twist element is a twist-pipe.
12. A skateboard according to claim 10 , wherein the direction-caster comprises:
a wheel support attached to the board having the shape of a wedge,
a roller arm pivotably connected to the wheel support, and
a roller rotatably connected to a free-end part of the roller arm.
