Abstract
A foot-pedaling device with bidirectional pedaling for constantly driving a loading wheel train in the same direction, wherein the pedaling direction is selected by the riding pedaler according to the operating status of his/her muscles and joints, or through the different driving directional input, to provide different-speed-change- ratio output.
Claims14
A bi-directional different-speed-ratio driving device with bi-directional manpower input, comprising:
- a bi-directional manpower-driven input device (101) arranged to be driven in both a first direction and a second direction opposite to the first direction, said input device (101) having a bi-directional output;
- a bi-directional different-speed-ratio speed change device (102) having a bi-directional power input directly or indirectly connected to the output of the manpower input device (101), said speed change device (102) having a speed change device output, wherein a speed change ratio of the speed change device (102) depends on a rotating direction of the bi-directional power input from the manpower input device (101) so that changing a rotating direction of the output of the manpower input device (101) changes a rotating speed of the speed change device output;
- a load (103, 105, 106, 107, 108, 109, or 112) directly or indirectly driven by the speed change device output,
- whereby rotation of the input device (101) in different directions exercises a variety of different muscles to reduce injuries and improve muscle strength and density of the different muscles.
