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.

There is provided a trampoline scooter (10) includes an elongate deck (12) including an upper surface (12a), a convex lower surface (12b), and rounded lateral edges (16) provided between the upper and lower surfaces (12a, 12b) for engaging a trampoline, a head tube (20) connected to the deck (12), and a column (22) disposed through the head tube (20), an upper end of the column (22) extending beyond the head tube (20) for receiving a set of handle bars.

A stationary jumping and trick bike is disclosed. An example device includes a frame assembly having a handlebar on a forward portion of the frame assembly and a seat on the frame assembly. A leg member including a leaf spring is connected to the frame assembly by a bracket having a plurality of ports selectable for pivotably attaching the leg member to the frame assembly to adjust pitch and/or angle of attachment of the leg member. A plurality of tensioners are connected between the leg member and the frame assembly. A foot rest is provided on the frame assembly. A standing and/or seated user holding the handlebar on the frame assembly can practice jumps and tricks by lifting and landing a lower portion of the leg member on a solid surface.

A pogo stick (100) comprising a frame (102); an elongate member (104) in sprung connection with the frame, for reciprocating motion between the elongate member and the frame; a liquid container (110) arranged, in use, to contain a liquid; and firing apparatus (108) arranged to utilise the reciprocating motion between the elongate member (104) and the frame (102) to expel the liquid in the liquid container (110) from the pogo stick (100).

A handheld bouncing device that is vertically oriented and centrifugally balanced including: (a) an elongated, compressible axle; (b) a planar body having a balanced symmetrical shape and a central aperture, the elongated compressible axle disposed within the central aperture such that a middle section of the elongated compressible axle is rotationally coupled to the planar body, such that the elongated compressible axle protrudes from the central aperture perpendicular to a plane of the planar body.

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.
