ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to skateboards.
2. Prior Art
A conventional skateboard is comprised of an elongated board with a pair of front wheels and a pair of rear wheels. In addition to rolling along the ground and making turns, skillful skateboard riders can make complex maneuvers with a board. Many maneuvers involve jumping or lifting the board off the ground. A rider can either lift it by hand, or step on its rear end to pitch up the front end. These methods are difficult to master, and are limiting in the type of maneuvers they enable a rider to perform. Although U.S. Pat. No. 4,135,726 to Beaver shows a skateboard with a handrail which may be used to lift the skateboard, the handrail is tall and rigid, so that the rider's freedom of movement is severely restricted by it.
OBJECTS OF THE INVENTION
Accordingly, objects of the present skateboard stirrup are:
to allow a rider to easily lift a skateboard for airborne maneuvers;
to allow a rider to stand on the skateboard in a conventional fashion;
to not limit a rider's freedom of movement; and
to be easily retrofitted to a conventional skateboard.
Further objects of the present invention will become apparent from a consideration of the drawings and ensuing description.
BRIEF SUMMARY OF THE INVENTION
A skateboard stirrup is comprised of a pair of hollow end caps for cupping over the front and rear ends of a skateboard, and a resilient band connected between the end caps. When the rider's feet are on top of the band, it is yielding enough to allow the feet to make full contact with the top of the board. When the rider's feet are inserted under the band, it is taut enough to lift the skateboard for airborne maneuvers when the feet are lifted.
