摘要翻译：曲柄装置，其能够在不增加曲柄臂的轨迹的情况下产生大的转矩。曲柄臂具有通过小齿轮纵向可滑动地联接在一起的第一和第二臂。第二臂在小齿轮的两侧形成两组齿条齿。小齿轮沿其周边具有多个齿，每当齿轮在相同的方向上转动半圈时，该齿适于与各组齿条齿轮交替地啮合。因此，每当曲柄臂转动180°时，曲柄臂的整个长度交替变为最大和最小。当曲柄臂的长度最大时，通过向曲柄臂施加驱动力，可以产生大的转矩。

摘要： PURPOSE: An expandable crank using a cylindrical cam or an inclined cam, and a bicycle using the same are provided to facilitate a rotary motion by lengthening a crank pedal when torque is applied, and shortening the crank pedal when the torque is not applied. CONSTITUTION: An expandable crank comprises a fixed arm(1), a moving arm(2), and a cylindrical cam(3). The fixed arm is coupled with a rotary shaft of a rotator for transferring torque. The moving arm is extended in a longitudinal direction inside of the fixed arm. The cylindrical cam is coupled with the inside of the moving arm in a vertical direction of the moving arm. A pedal is composed of a pedal shaft(41) coupled with an exposed end of the moving arm, and pedal plates(42). The pedal plates are coupled with the pedal shaft so as to prevent relative rotation. A pair of bevel gears are respectively coupled with a cam shaft of the cylindrical cam and the pedal shaft of the pedal.

摘要： An expandable crank arm using a cylindrical cam is provided to easily and rapidly climbing a slope with the same power by giving larger torque to a driving unit than a conventional bike. An expandable crank arm includes a fixing arm(1), an operation arm(2), a cylindrical cam(3), a pedal(4), and a pair of bevel gears(5). The fixing arm is coupled with a rotating shaft of a rotating body and has a cam guide(13) engaged with a guide groove or a guide projection of the cylindrical cam. The operation arm is expanded and contracted in the fixing arm. The cylindrical cam is axially coupled with the operation arm and is engaged with the cam guide of the fixing arm by having the guide groove or the guide projection. The pedal is composed of a pedal shaft(41) coupled with an end of the operation arm and a pedal plate(42) coupled with the pedal shaft. The pair of bevel gears are coupled with a cam shaft of the cylindrical cam and the pedal shaft of the pedal.

摘要： 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.
