Abstract: PURPOSE: A variable type pedal driving device is provided to gain maximal driving energy with minimal physical energy consumption by extending a length thereof during travel between a crankshaft delivering torque of a pedal to a rear wheel and the pedal. CONSTITUTION: A pedal driving device consists of power delivery units(6,6') delivering drive power of pedal to a main shaft, installed in cases fixed in a main shaft established in a frame(1), pedals(7,7') combined to slide pipes(8,8'), crankshafts(5,5') slidably combined to slide holes and a chain sprocket(9) connected to a rear wheel(15) and to a chain(16). On stepping upon the pedals, torque enables the pedals to rotate the crankshafts and the slide pipes combined with the pedals sliding along the crankshafts. Further, rotational radius between the main shaft with crankshafts and the pedals is varied and distance therebetween is enlarged maximally during rotation in a proceeding direction. Thereby, distance among pedals(7,7') offering travel energy, rotating shafts(61,61') of cases as a main moving shaft of torque and a main shaft of disks drives the pedals and rotational direction is enlarged maximally while driving in a proceeding direction and thus efficient driving energy is obtained.

Abstract translation: 目的：提供一种可变式踏板驱动装置，通过在踏板的曲轴输送转矩与后轮之间的行驶期间延伸其长度与脚踏板之间的最小的物理能量消耗来获得最大的驱动能量。 构成：踏板驱动装置由将脚踏板驱动力传递到主轴的动力输送单元（6,6'）组成，其安装在固定在构成框架（1）的主轴中的踏板（7,7'）中， 组合以滑动管道（8,8'），可滑动地组合以滑动孔的曲轴（5,5'）和连接到后轮（15）和链条（16）的链轮（9）。 踏上踏板时，扭矩使踏板能够使曲轴旋转，滑动导管与踏板相结合，沿曲轴滑动。 此外，具有曲轴的主轴与踏板之间的转动半径是变化的，并且它们之间的距离在向前的方向旋转期间被最大化地增大。 因此，提供旅行能量的踏板（7,7'）之间的距离，作为扭矩的主移动轴的壳体的旋转轴（61,61'）和驱动踏板和旋转方向的盘的主轴的距离在驾驶时最大化地被放大 获得了前进的方向，从而获得了有效的驱动能量。
