    • The vehicle toy includes a split central roller with end rollers on either side of it, a platform between the segments of the split central roller, side members along the ends of the rollers, and vertical members leading to handrails above the rollers to be grasped by the person standing on the rollers to manipulate the vehicle. The central roller is positioned below the end rollers and the vehicle is symmetrical, allowing either end roller to be selectively engaged with the supporting surface, along with the central roller.

    • Apparatus that simulates the exercise obtained in either of two modes of bicycling, e.g. sit-down, normal pedalling; and stand-up, hill climbing pedalling. Two different systems are disclosed, both yielding the desired bimodal choice of exercise. One system includes the use of clutches and gearing that allows switching between the normal 180.degree. fixed pedal relationship and a relationship that assists each pedal through bottom and top dead center, with the unweighted pedal being returned by the force generated by the other pedal as this other pedal is moved through the most powerful portion of the pedalling cycle. The second system includes the use of locking ratchets, adjustable spring returns, and adjustable stops to allow switching between the normal 180.degree. fixed pedal relationship and a relationship that avoids passage of the pedals through top and bottom dead center and confines all pedal movement to the power portion of the pedalling cycle. In both systems the "down" pedal is effectively braked or stopped to provide a step-up platform to provide for body lifting in the "stand-up" mode.
    • 模拟以两种自行车模式中的任一种获得的运动的装置,例如。 坐下来,正常踩踏; 并站起来,爬山踩踏。 公开了两种不同的系统,两者都产生所需的双模式运动选择。 一个系统包括使用离合器和传动装置,其允许在正常的180度固定踏板关系之间切换,并且通过底部和上部死点帮助每个踏板的关系,其中未加权踏板由另一个踏板产生的力返回,因为这样 其他踏板通过踏板循环最强大的部分移动。 第二个系统包括使用锁定棘轮,可调节的弹簧返回和可调节的止挡,以允许在正常的180°固定踏板关系之间切换,并避免踏板通过顶部和下部死点的通道,并将所有踏板运动限制在 动力部分的踏板循环。 在两个系统中,“下”踏板被有效地制动或停止,以提供升降平台,以提供“立式”模式下的身体提升。
