Rider propelled rotatable riding device

Abstract

An amusement device comprises a rider propelled rotatable riding device, such as a roundabout or merry-go-round, on which one or more riders propel themselves in a circular path. The device has two concentric vertically undulating tracks of different radii, such that they constitute inner and outer tracks. The undulations preferably are 180.degree. out of phase on the respective tracks. A rotatable structure is mounted for rotation concentrically with respect to the track, and carries a pair of freely rotatable wheels generally vertically movable for rolling along the undulating surfaces of the respective tracks. The wheels are coupled with rider controlled linkage means permitting a rider to selectively intermittently urge either wheel against its undulating track surface with increased force relative to the other wheel, whereby the supporting structure can be rotatably driven by selectively and alternately urging either wheel against a downhill portion of its undulating track relative to the force urging the other wheel against a non-downhill portion of the other undulating track. Preferably the linkage includes a seat which is rockably mounted, so that the propelling force can be effected by a rocking movement of the rider on the seat.
