Benefits of technology

"The present invention is a pneumatic pogo stick that uses a piston and a cylinder to create a spring-like force. The pogo stick is designed to be strong, durable, and lightweight. The use of a plastic material, such as PVC or polycarbonate, allows for easy evaluation of the cylinder and piston without having to disassemble the device. The pogo stick is also designed to be maneuverable and controllable during use, with a non-circular slider shaft and bottom assembly that prevents rotation of the piston. The technical effects of the invention include higher power to weight ratio, potential for higher speed, and improved maneuverability and control."

Problems solved by technology

Such a pogo stick, however, has many shortcomings in both construction and functionality and fails to address any of the problems encountered when attempting to use compressed air as a spring, such as smoothness of rebound.
Such a device is overly complicated and requires multiple complex parts for assembly and operation.
Furthermore, such a device is relatively heavy and therefor decreases the lift capabilities of such a device.

Embodiment Construction

[0047]FIG. 1 illustrates a first embodiment of a pneumatic pogo stick, generally indicated at 10, in accordance with the principles of the present invention. The pogo stick 10 is comprised of a plastic tube 12 which forms an outside housing to which various other components of the device are attached and a cylinder portion 15 of a piston 14 / cylinder 15 arrangement. Plastics such as PVC or polycarbonate are preferable over other materials including steel and aluminum because they are strong, lightweight, resilient, inexpensive, and dent resistant. An alternate material that could be used for the cylinder 12 is cellulose acetate butyrate. Such plastic materials are preferred since metals such as aluminum or steel, if dented, may cause the pogo stick to leak air between the cylinder 15 and piston 14 during use or partially or fully obstruct movement of the piston 14 relative to the cylinder 15 so that the device 10 is no longer operable. Thus, despite side impacts, the cylinder 15 must...

Abstract

A pneumatic pogo stick is comprised of an elongate cylindrical housing which forms a cylinder. The housing is formed from a clear polycarbonate plastic. A top cap is attached to one end of the housing to form the top of an air chamber. A plastic piston, slidable within the cylinder, forms the bottom of the air chamber. An elongate shaft is coupled to the bottom of the piston and is moveable therewith, extending from the distal end of said housing as the piston moves within the cylinder. A bottom bracket assembly is attached to the bottom of the housing and a bushing for maintaining the lateral position of the shaft relative to the housing is attached to the bottom bracket assembly. The bushing prevents the shaft from rotating relative to the housing. User foot supports are also attached to the bottom bracket for supporting the feet of the user and handle bars are attached to the top cap for grasping with the hands of a user.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of application Ser. No. 10 / 278,075, filed Oct. 21, 2002, which claims the benefit of U.S. Provisional Application No. 60 / 335,524, filed Oct. 19, 2001.BACKGROUND [0002] 1. Field of the Invention [0003] The present invention related generally to a pogo stick, and more specifically, to a pneumatic pogo stick that utilizes lightweight and durable materials to maximize the performance and reliability of a pneumatic pogo stick. [0004] 2. Background of the Invention [0005] A conventional pogo stick utilizes a coil spring within a hollow tube housing to create an upward force when compressed by a user to propel the user in an upward direction. In order to get more lift than can be provided with a coil spring and without increasing the weight of the pogo stick itself, it has been recognized in the art that an air filled cylinder / piston arrangement can produce increased propulsion or lift for the same length of s...
