摘要： A velocipede comprising a rigid frame with front and rear wheels and a crank operably connected to the rear wheels. A first member has its front end portion pivotably connected to the frame front end such that the first member is movable between upper and lower positions above and below a horizontal line passing through the pivot. A second member has a first end pivotably connected to the first member rear end portion and a second end pivotably connected to the crank such that reciprocating movement of the first member rear end portion causes the second member to rotate the crank. A third member includes a pivot disposed at its intermediate portion and has its front and rear ends movable between upper and lower positions. A pair of pedals are pivotably secured to the third member front end and movable therewith between the upper and lower positions. A fourth member has one end pivotably connected to the first member rear end portion and a second end pivotably connected to the third member rear end such that when the first member is in the lower position, the pedals are at their upper position and when the first member is in the upper position, the pedals are in their lower position. A seat is disposed intermediate the first member front and rear ends and substantially directly above the third member pivot such that when the pedals are at their upper position, the pedals are slightly forward of the seat.
摘要翻译：包括具有前轮和后轮的刚性框架和可操作地连接到后轮的曲柄的旋转体。第一构件的前端部可枢转地连接到框架前端，使得第一构件可在通过枢轴的水平线上方和下方的上部位置和下部位置之间移动。第二构件具有可枢转地连接到第一构件后端部的第一端和可枢转地连接到曲柄的第二端，使得第一构件后端部的往复运动使第二构件旋转曲柄。第三构件包括设置在其中间部分处的枢轴并且其前端和后端可在上部位置和下部位置之间移动。一对踏板可枢转地固定到第三构件前端，并且可以在上部位置和下部位置之间移动。第四构件具有可枢转地连接到第一构件后端部的一端和可枢转地连接到第三构件后端的第二端，使得当第一构件处于下部位置时，踏板处于其上部位置，并且当第一构件会员处于上位，踏板处于较低位置。座椅位于第一构件前端和后端之间并且基本上直接位于第三构件枢轴的上方，使得当踏板处于其上部位置时，踏板稍微向前倾斜。
