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.
A self propelled merry-go-around is provided including a base having a plurality of linear feet and a vertical stanchion fixedly coupled to the feet and extending upwardly therefrom. A pivoting assembly includes at least one arm rotatably coupled to a top end of the vertical stanchion. The arm has an outboard end with a seat and at least one post having a bar coupled to both a top end and a bottom end thereof in perpendicular relationship with the post. A central extent of the post is pivotally coupled to at least one end of the second arm just inward of the corresponding seat. A drive assembly is provided including a drive member with an inverted L-shaped configuration fixedly coupled to a top of the vertical stanchion. At least one interconnect rod has a first end pivotally coupled to the post of the arm of the pivoting assembly and a second end pivotally coupled to an outboard end of the drive member for effecting the rotation of the pivoting assembly.
