    • PROBLEM TO BE SOLVED: To provide an exercise bicycle the saddle of which performs not only parallel motion but also turning complex periodical movement when a user rides the bicycle for exercise.SOLUTION: A planar four-link mechanism with a crank is provided. A bicycle frame 5 is used as the machine frame of the planar four-link mechanism. A saddle 2 is fixed to a link 8 connected indirectly with the bicycle frame 5 in the planar four-link mechanism. An axis 10 is a crankshaft, and one end of the link 8 is rotationally connected with the link shaft journal of the crankshaft 10 while the other end is connected to a member connected to the bicycle frame 5. The exercise bicycle includes the saddle 2 capable of performing not only the parallel motion but also the turning periodical movement.
    • 要解决的问题:为了提供一种运动自行车,其骑马不仅执行平行运动,而且还在使用者骑自行车进行运动时转动复杂的周期性运动。 解决方案:提供具有曲柄的平面四连杆机构。 自行车架5用作平面四连杆机构的机架。 鞍座2固定在与平面四连杆机构中的自行车车架5间接连接的连杆8上。 轴线10是曲轴,连杆8的一端与曲轴10的连杆轴颈旋转连接,另一端连接到与自行车车架5连接的部件。运动自行车包括能够 不仅执行平行运动,而且还进行了转动周期性运动。 版权所有(C)2013,JPO&INPIT
