## Abstract

A manual mechanical leg-stepping power generating apparatus includes a leg pedal installed separately on both left and right sides of a seat pole of a bicycle, moved up and down at a position adjacent to a rider's thigh muscle, and coupled to a connecting shaft through a leg pedal link rod. Another side of the connecting shaft is coupled to a power generator shaft on the seat pole by using a support rod. The leg pedals are moved up and down alternately to drive a power generator installed in a power generator to generate electric power. When a rider rides the bicycle, kinetic energy is generated by a force applied by the rider's thigh onto the leg pedals and converted into electric energy by the leg pedals, power generator shaft and the power generator set, such that the electric energy can be supplied for the use by electric devices.

## Claims

### Claim 1

A manual mechanical leg-stepping power generating apparatus, comprising a power generator shaft installed on a seat pole on a bicycle frame, a leg pedal installed separately on both left and right sides of the seat pole, and moved up and down adjacent to a position corresponding to a rider's thigh, and each leg pedal being coupled to a connecting shaft by using a leg pedal link rod, and another end of the connecting shaft being coupled to a power generator shaft by using a support rod, and the power generator shaft being coupled to a power generator set, and electric power generated by a power generator in the power generator set being supplied for the use of an electric device.

### Claim 2 (depends on 1)

The manual mechanical leg-stepping power generating apparatus of claim 1, wherein each link rod of the leg pedal is a structure with adjustable length, height, angle, shape, and installation position corresponding to the rider's thigh.

### Claim 3 (depends on 1)

The manual mechanical leg-stepping power generating apparatus of claim 1, further comprising a battery installed on the power generator shaft, and the battery having one selected from the collection of an electric power output slot, an illumination lamp, a warning lamp, an electric power output switch and an electric meter.

### Claim 4 (depends on 1)

The manual mechanical leg-stepping power generating apparatus of claim 1, wherein the seat pole further includes a chair cushion.

### Claim 5 (depends on 1)

The manual mechanical leg-stepping power generating apparatus of claim 1, wherein the seat pole is integrated formed with the bicycle frame.
