Pneumatic pogo stick
First Claim
1. A pneumatic pogo stick, comprising:
- an elongate cylindrical housing having a proximal end and a distal end forming a cylinder, said elongate cylindrical housing formed from plastic;
a top cap attached proximate the proximal end of the housing;
a piston slidable within the cylinder and forming a substantially air tight chamber between the piston, cylinder and top cap;
an elongate shaft coupled to said piston and moveable therewith extending from said distal end of said housing;
a bottom bracket assembly attached proximate the bottom of the housing;
a guide for maintaining the lateral position of the shaft relative to the housing as the shaft moves with the piston;
at least one user foot support coupled to the bottom bracket assembly; and
at least one hand grip member coupled to said top cap.

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.

15. A pneumatic pogo stick, comprising:
-
an elongate cylindrical housing having a proximal end and a distal end forming a cylinder, said elongate cylindrical housing formed from an at least partially transparent plastic;
a top cap attached proximate the proximal end of the housing, the top cap having an attachment portion for attaching to the housing;
handle bars attached to the top cap for grasping by a user;
a piston assembly slidable within the cylinder and forming a substantially air tight chamber between the piston, cylinder and top cap;
an elongate shaft having a non-circular cross-section coupled to said piston and moveable therewith extending from said distal end of said housing;
a bottom bracket assembly attached proximate the bottom of the housing;
a bushing attached to the bottom bracket, said bushing defining an aperture of a non-circular shape similar to that of the elongate shaft for maintaining the lateral and rotational position of the shaft relative to the housing as the shaft moves with the piston;
a pair of user foot supports coupled to the bottom bracket assembly; and
a pair of handle bars attached to the top cap for grasping by a user. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
