RECIPROCATING FOOT DRIVE FOR BICYCLE Russian patent published in 2022 - IPC B62M1/24 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to reciprocating foot drives for bicycles. The drive contains a body, front and rear sliders, left and right L-shaped levers with pedals, a cable, a pulley, two anthers. The front and rear sliders are installed in the internal cavity of the housing in the same plane parallel to each other with the possibility of placing a bicycle chain between them. Each slider is movably mounted between two guide bars fixedly fixed on the rear and front end faces of the body, respectively. The front and rear sliders are provided with two spring-loaded grippers movably mounted on the axles between the sidewalls and engaged with the links of the bicycle chain when the slider moves down. The front and rear sliders are equipped with two stops. The stops are mounted above the spring-loaded grips. The upper and lower guide blocks for the bicycle chain, mounted on supports, are rigidly fixed, respectively, on the upper and lower faces of the housing. The pulley is installed on the upper face of the housing on the opposite side from the installation site of the upper guide block.

EFFECT: increased efficiency of the drive.
