Abstract: A pneumatic pogo stick is provided that utilizes compressed air like a spring to have a potentially higher power to weight ratio than a comparable coil spring pogo stick. The pneumatic pogo stick includes an elongate cylindrical housing which forms a cylinder. Improvements are also provided to the piston and air shaft that allow for reduced hammering and a lower maximum compression ratio in order to provide relatively smooth jumping and landing while propelling a user to greater heights. Examples of such improvements include a hollow air shaft and modifications to the shape and structure of the piston.

Abstract: Embodiments of the present disclosure relate to pneumatic pogo sticks having features that allow for the jumping and/or landing characteristics of the pogo stick to be varied. These characteristics may even be modified by a user during use. For example, the housing of the pogo stick may have multiple air chambers and air may be selectively transferred between the multiple air chambers. The transfer of air may change the volume, air pressure, compression ratio, and spring-characteristics of the one or more air chambers in which air is compressed during the compression stroke of the pogo stick. These changes will affect the jumping and/or landing characteristics of the pogo stick and in some cases may allow the user to obtain a greater jump height. At the same time, these features may also allow the pogo stick to be collapsed so that it can be easily stored, packaged, and transported.

Abstract: A pneumatic pogo stick is provided that utilizes compressed air like a spring to have a potentially higher power to weight ratio than a comparable coil spring pogo stick. The pneumatic pogo stick includes 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 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.

Abstract: Game items that enable a user to conduct an online transaction related to a purchasable product are presented. Game items can comprise a game component having an indicia related to a purchasable product, and a link key. The link key can be a barcode, QR code, radio frequency identifier, or other symbol encoded with data that enables an electronic device to conduct an online transaction.
