The invention discloses a ratchet-driven self-propelled scooter, comprising a scooter body and a transmission mechanism set on the scooter body; the invention provides a manpower self-propelled scooter with simple structure, light weight and low cost; step on a driving pedal to put a driving clamp in motion, thereby a pressing arm wheel drives a ratchet arm, then a ratchet pawl leads an axle to drive the rear traveling wheels to rotate, so that the scooter body moves; after releasing the driving pedal, the driving pedal is reset through a torsion spring, likewise repeatedly stepping to increase the driving force for the scooter body; the device possesses a complete scheme, simple structure, convenient operation, low cost, which is worthy of widespread promotion.

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles like fitness equipment or an exercise bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to a knee and a hip joint of the user seated on the exercise device, smart device and an application of the smart device.

Demountable devices for transformation of treadle lever rocking movement into rotary movement of bicycle's drive shaft consist of two main units: redesigned driving unit for conventional bicycles and a reverse gear. Both units interact with each other through a flexible transmission. The devices can be mounted on most conventional bicycles. Bicycle's movement is provided by regular pressing of the cyclist's leg on the treadle lever. Length of the treadle lever can be adjustable.

Vehicle including a frame, a seat mounted to the frame, wheels rotatably mounted on the frame, and drive mechanisms for causing rotation of one wheel. Each drive mechanism includes an arm pivotally attached to the frame at one end, a weight and attached pedal at an opposite end of the arm, and a guide member including a bump and that moves in conjunction with movement of the weight. The guide member has a first end region at which the guide member is pivotally attached to the frame and a second, opposite end region which is free. A roller attached to the arm moves along the guide member during pivotal movement of the arm to cause pivoting of the guide member as the roller engages with the bump. An energy transfer system converts pivotal movement of the guide member into motive power to rotate the wheel.

The present invention disclose a continuously variable reciprocating prime mover. The feature of this continuously variable reciprocating prime mover is that the reciprocating rotatory motion of the legs is modified into the reciprocating linear flexion and extension of the legs, by which one leg is flexed while the other leg is stretching, the combined force of the legs can be multiplied by the force. After each linear motion stroke is completed, the reverse linear motion stroke is repeated, and the driving direction remains unchanged. At any moment of the full stroke of the reciprocating linear flexion and extension of the legs, both can generate 2 times of the instantaneous power equivalent to the maximum moment point of the circular rotation.

A reciprocating mechanism includes a first connecting element, a crankshaft and a second connecting element. The crankshaft includes a rotation shaft, a first following element and a second following element. The first following element is pivotally disposed on one side of the rotation shaft and movably coupled to the first connecting element. The second following element is pivotally disposed on the other side of the rotation shaft, and a first angle is formed between the first following element and the second following element. The second connecting element is movably coupled to the second following element. The first following element and the second following element are configured to rotate around the rotation shaft so as to be movably coupled to and cause each of the first connecting element and the second connecting element to reciprocate and cyclically pivot along an arc-shaped trajectory.

Vehicle includes a frame, a seat arranged on the frame, a wheel rotatably mounted on the frame, an elongate directional slider, a pedal on the directional slider that slides between first and second positions, a main drive chain connected to the first wheel, a main drive sprocket that rotates the main drive chain and thus the first wheel, a flywheel that rotates the main drive sprocket, and an energy generating system that converts sliding of the pedal on the directional slider into rotational force to rotate the flywheel. The energy generating system may include a first electrical coil assembly connected to the pedal, a second electrical coil assembly in connection with the directional slider and that cooperates with the first electrical coil assembly to cause generation of electricity, and an electrical motor that is powered by the generated electricity and is coupled to the flywheel to rotate the flywheel.
