Patent Application

The present invention is designed to propel users of skateboards.
One of the newest trends in skateboarding is the use of street paddles to propel skateboards. The inventors are aware of a street paddle sold by Kahuna Creations that is used to propel skateboards. The KAHUNA street paddle uses circular structures at the end of the paddle to provide the traction to propel skateboards.
The inventors are also aware of a wedged street paddle that is being manufactured in Florida.
The present invention provides a telescoping paddle having a piston spring mechanism attached to a piston leg with a rubber push tip. The present invention's rubber push tip not only creates surface tension with the ground enabling better traction, but also provides an added means to propel a rider forward.
Note, none of the street paddles recited above provide riders with telescoping paddle having a piston spring and piston leg which enables riders to push start their skateboards using their upper body and arms, thereby enabling them to maintain a constant velocity.
The present invention differs from prior paddles because it allows a user to adjust the height with its telescoping shaft which is adjustable. This one size fits all application allows riders of different heights and ages to share and use the same paddle.
For the foregoing reasons, there is a need for the telescoping paddle that will allow users to maintain a constant speed, increase rider stability by providing a third leg, and will accommodate users of varying heights and ages.
The present invention is directed to a telescoping paddle that will allow users of skateboards to maintain a constant speed, increase rider stability by providing a third leg, and will accommodate users of varying heights and ages.
The present invention is a telescoping paddle for use with skateboards. The telescoping paddle comprises a telescoping shaft having a top shaft, a bottom shaft, a piston leg, a piston spring attached to the bottom shaft and the piston leg, and a rubber push tip attached to the piston leg. Attached to the top side of the top shaft is a rounded T-form handle. Adjacent to the bottom portion of the top shaft is a grip. Below the grip is a telescoping adjuster locking device connecting the bottom side of the top shaft with the top side of the bottom shaft. The rubber push tip has a top and a bottom side, the bottom side has an apex from which the rubber push tip curves downward so as to form a ball like surface, and the top side of the rubber push tip attaches to the piston leg.
An object of the present invention is to provide a telescoping paddle that will allow a user of skateboards to maintain a constant speed by using his arms to lunge the paddle downward by which a piston leg compresses a spring and upon release catapults the skateboard and rider forward.
Another object of the present invention is to increase rider stability by providing a third leg.
Yet, another object of the present invention is to allow skateboard users of different heights and ages to benefit from the telescoping paddle.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and drawings where:
As seen in
In a further embodiment of the present invention, the street paddle might further comprise of a piston spring 30 and a piston leg 40. The piston leg 40 has a top 40a and a bottom side 40b, wherein the bottom side of the piston leg 40b attaches to the top side of the rubber push tip 50a rather than the top side of the rubber push tip 50a attaching to the bottom side of the bottom shaft 20b. The piston spring 30 has a top 30a and a bottom side 30b, wherein the bottom side of the piston spring 30b attaches to the top side of the piston leg 40a and wherein the top side of the piston spring 30a inserts within the bottom side of the bottom shaft 20b, and wherein the top of the piston leg 40a also inserts within the bottom side of the bottom shaft 20b, and wherein the bottom side of the bottom shaft 20b defines a means for stopping the piston spring at a position 35 that is at least four inches from the bottom side of the bottom shaft 20b.
The means for stopping the piston spring 35 is a stop that is bored within the bottom shaft 20 so as to receive the spring 30.
In an embodiment of the present invention, the top shaft 10 has a length of at least 28 inches and at most 34 inches, the bottom shaft 20 has a length of at least 32 inches and at most 36 inches, the piston leg 40 has a length of at least four inches, and the piston spring 30 has a length of at least four inches.
In another embodiment of the present invention the grip 25 is might be made of soft foam and the telescoping shaft might be made of an aluminum composite.
An advantage of the present invention is that it provides a telescoping paddle that allows a user of skateboards to maintain a constant speed by using his arms to lunge the paddle downward by which a piston leg compresses a spring and upon release catapults the skateboard and rider forward.
Another advantage of the present invention is that it increases rider stability by providing a third leg.
Yet, another advantage of the present invention is that it allows skateboard users of different heights and ages to benefit from the telescoping paddle.
The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the invention. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention. However, this invention can be embodied in other fauns without departing from the spirit or essential attributes thereof Accordingly, reference should be made to the following claims, rather than to the foregoing specification, as indication of the scope of the invention.
