  • Patent number: 10238907
    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.
