    • A generally circular base panel having a central area is provided for disposition on a horizontal support surface and a rotary platform is disposed above the base panel and includes support wheels rollingly engaged with the upper surface of the base panel. The platform is pivotally anchored to the base panel for rotation relative thereto about an upright axis extending through the central area of the base panel and the platform includes two relatively angulated generally straight sides converging toward a point at least closely adjacent the axis of rotation of the platform. The platform further includes a convex arcuate side interconnecting the divergent ends of the straight sides and having its opposite ends generally equally spaced from the axis of rotation of the platform relative to the base, the arcuate side of the platform extending through an arc of approximately ninety degrees. The platform has child support structure thereon and at at least one child support structure includes a manually drivable wheel disposed outwardly of one of the straight sides of the platform and rollingly engaged with the base panel whereby a child disposed on the platform may drive the wheel and thus cause the platform to rotate about its axis of rotation relative to the base panel.
    • 提供具有中心区域的大致圆形的底板,用于设置在水平支撑表面上,并且旋转平台设置在底板上方,并且包括与基板的上表面滚动接合的支撑轮。 平台枢转地锚固到基座面板上以围绕延伸穿过基座面板的中心区域的直立轴线相对于其旋转,并且该平台包括两个相对成角度的大致直的边,其朝着至少紧密相邻的旋转轴线的点会聚 平台。 该平台还包括一个凸起的弓形侧面,其互连直边的发散端部,并且其相对的端部大体上与平台相对于基座的旋转轴线等间隔开,平台的弧形侧延伸通过大约九十 度。 平台在其上具有儿童支撑结构,并且在至少一个儿童支撑结构包括设置在平台的直立侧之一的外侧的可手动驱动的轮,并与基座面滚动接合,由此设置在平台上的儿童可以驱动车轮和 从而使平台相对于基座围绕其旋转轴线旋转。
