  • Patent number: 7011608
    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.
