摘要： The conventional pedal crank drive from DE 43 11 404 C2 has second crank arms (2), connected to the outside of the first crank arms (1), by means of a rotating joint (3) and each comprises a pedal (5), with adjustable angular inclination. Said drive system has the problem that the extended pedal crank unit does not have the required stiffness before the bottom deadpoint to convert the full pedal traction force into torque.According to the invention, said problem is overcome whereby a carrier plate (4) is arranged on the first crank arm in the vicinity of the rotating joint (3) with an angular adjustment and a ratchet mechanism (7) is arranged on the second crank arm, such that the rotating joint is periodically locked in the region of the bottom deadpoint and hence a double length rigid force arm is formed, whereby the pedal traction force is ergonomically converted into maximum torque with the large radius from A to B.The synchronous pedal crank drive is universally suited for bicycles, bicycle ergometers, fitness and health training, during times of rehabilitation as well as in sports medicine and occupational medicine, as well as for specialised pedal-driven equipment for example, pedal-driven aircraft, stationary bikes, pedal boats, for astronauts in space, and so on.

摘要： The present invention relates to a mechanical element, and more particularly, to a crank connected to a bicycle pedal or a handle for rotating a rotary body and to a bicycle using the same. The present invention uses a cylindrical cam, an end cam, or a swash plate cam, and the shafts of these cams and a shaft of a pedal or a handle for applying force are equipped with a miter gear (a bevel gear the number of teeth of which is 1:1 and the shaft angle of which is 90 degrees), such that the crank retracts/extends one time per one rotation of the pedal or the handle. The retractable/extendable crank of the present invention is advantageous in that the length of the crank is elongated to generate a large amount of rotating force in a force-applying section, and shortened in a section where no force is applied to reduce the actuating space occupied by the crank and apply a large amount of torque to the rotary body from the same force, without deviating from the normal motion range of the arms or legs during rotation. The retractable/extendable crank of the present invention has a significantly rigid structure and provides reliable operation, and thus is suitable as a driving crank to be connected to a pedal of a bicycle. As compared with conventional bicycles, the bicycle using the crank of the present invention is supplied with a larger amount of rotating force in proportion to the elongation of the crank from the same force, thus enabling the bicycle of the present invention to travel quickly with less force and climb a steep upward slope in an easy manner.

摘要翻译： 本发明涉及一种机械元件，更具体地，涉及一种连接到自行车踏板或用于旋转旋转体的手柄的曲柄和使用其的自行车。 本发明使用圆柱形凸轮，端部凸轮或斜盘凸轮，并且这些凸轮的轴和用于施加力的踏板或手柄的轴配备有斜齿轮（锥齿轮的齿数 其角度为1：1，其轴角为90度），使得曲柄在踏板或手柄的每转一次缩回/延伸一次。 本发明的可伸缩曲柄的优点在于，曲柄的长度是细长的，以在施力部分产生大量的旋转力，并且在没有施加力的部分中缩短以减小致动空间 由曲柄占据，并且从相同的力向旋转体施加大量的扭矩，而不会在旋转期间偏离臂或腿的正常运动范围。 本发明的可伸缩曲柄具有明显的刚性结构并提供可靠的操作，因此适合作为连接到自行车踏板的驱动曲柄。 与传统的自行车相比，使用本发明的曲柄的自行车由相同的力与曲柄的伸长率成比例地被提供更大量的旋转力，因此本发明的自行车能够以更少的速度快速行进 以轻松的方式力量爬上陡峭的上坡。

摘要： This invention relates to a bicycle having a driving force transmitting mechanism with oscillating fulcrum point. A crank lever is connected between a sprocket and the one of pedal levers. When a rider steps on the pedals alternatively, force of the pedal levers generated by the oscillation of the pedal levers is transmitted to the sprocket through the crank lever. When the pedal levers oscillate, an oscillating fulcrum point of the pedal lever is moved, not fixed, in a lateral direction within the sliding part. The rotating force of the sprocket is transmitted to the rear wheel through a chain. With such an arrangement, a configuration of the rotating force transmitting mechanism for the rear wheel is simplified. Even if the locus Q of motion of the pedal is different in the first half period (a stepping-on period) and the second half period (a stepping-up period), a smooth rotation of the pedal is assured.

摘要： This invention relates to a bicycle having a driving force transmitting mechanism with oscillating fulcrum point. A sliding part is provided with a dust cover or a brush to prevent dust and the like from being entered therein and to remove the dust, if entered, therefrom. When a rider steps on the pedals alternatively, force of the pedal levers generated by the oscillation of the pedal levers is transmitted to the sprocket through the crank lever. When the pedal levers oscillate, an oscillating fulcrum point of the pedal lever is moved in a lateral direction within the sliding part. The rotating force of the sprocket is transmitted to the rear wheel through a chain. Even if the locus Q of motion of the pedal is different in the first half period (a stepping-on period) and the second half period (a stepping-up period), a smooth movement of the pedal is assured. Such a smooth movement can be kept enough by the dust cover.

摘要： This invention relates to an improved lever driven bicycle including a shifting mechanism for controlling a drive ratio between the oscillating lever and the drive wheel. The drive lever arrangement may be located about the front or rear wheels of the bicycle and, when about the rear wheel, may include a sole lever or dual levers. The drive lever arrangement includes a drive lever, a force applicator, a shifting mechanism, and a force converter which together transform the oscillating displacement of the lever to a rotation of the drive wheel. The shifting mechanism includes a slide block located about the lever which engages with the drive lever upon downward motion of the drive lever and controllably slides along the drive lever upon upward motion of the drive lever. The position of the slide block corresponds to a drive ratio between the drive lever and the drive wheel.

摘要： A crank device can produce a large torque without increasing the locus of the crank arm. The crank arm has first and second arms which are longitudinally slidably coupled together through a pinion. The second arm is formed with two sets of rack teeth on both sides of the pinion. The pinion has along its circumference a plurality of teeth which are adapted to alternately come into meshing engagement with the respective sets of rack teeth every time the crank arm makes a half turn in the same direction. Thus, the entire length of the crank arm alternately becomes maximum and minimum every time the crank arm turns by 180.degree.. By applying a driving force to the crank arm when the length of the crank arm is maximum, it is possible to produce a large torque.
