Abstract

A device for mastering skate board tricks and maneuvers comprises a frame. The frame has a top and the frame is adapted to rest on a support surface. A spring board is suspended from the frame by stretchable straps. A foot deck is rotationally secured to the spring board and is secured to the spring board to limit or eliminate relative vertical motion between the spring board and the foot board.

Claims

1. A device for mastering skate board tricks and maneuvers comprising a frame, said frame comprising a top and said frame being adapted to rest on a support surface, at least three elastic cords being attached to said frame;

said at least three elastic cords being connected to a spring board deck such that said spring board deck is suspended above said support surface and below said top of said frame;

a rotational bearing system being secured to said spring board deck and a foot deck being secured to the said rotational bearing system such that said foot deck is capable of rotational movement relative to said spring board deck and said foot deck is secured against substantial vertical movement relative to said spring board deck.

2. The device of claim 1 further comprising at least two protrusions connected to a lower surface of said spring board deck, said protrusions being sized to simulate the geometry of skateboard trucks and wheels and said protrusions being arranged such that each protrusion creates a line contact with said support surface.

3. The device of claim 1, wherein said frame comprises at least three support legs, said at least three support legs being temporarily secured together such that said frame can be collapsed for storage.

4. The device of claim 1, wherein with said elastic cords are at least one of (1) removably attached to said frame and (2) removably connected to said spring board deck.

5. The device of claim 1, wherein said rotational bearing system comprises an adapter, said adapter being disposed between said foot deck and a balance of said rotational bearing system.

6. The device of claim 1, wherein said frame comprises a handlebar.

7. The device of claim 1 further comprising a plurality of cord anchors, said cord anchors being interposed between said at least three elastic cords and said frame.

8. The device of claim 7, wherein at least one cord adjustment clamp is connected to at least one of said at least three cords.
