VESSEL PEDAL DRIVE, INFLATABLE VESSEL, METHOD OF INFLATABLE VESSEL MOVEMENT ON WATER AND METHOD OF DRIVE MOUNTING ON INFLATABLE VESSEL Russian patent published in 2017 - IPC B63H16/00 B63H23/00 

FIELD: engines.

SUBSTANCE: invention relates to mechanical engines and intended for use on inflatable boats. Inflatable vessel pedal drive comprises pedal unit, seat, control lever, keel and propeller. Pedal unit consists of two pedals, wherein left and right pedals are attached with possibility of rotation to first and second crank rods. First and second rods are correspondingly secured at first and second shafts. On first and second crank rod shafts are secured first and second driving wheels. Pedal unit is installed on withdrawable structure, which by one end is fixed under drive seat, and by other is through adjusting mechanism. First and second driving gear wheels are made with possibility to transmit torque via first and second crank rod chains to first and second crank rod driven gear wheels, respectively, which are arranged in reduction gear unit. Reduction gear unit is installed under seat on withdrawable structure, which is intended to tension chains of first and second crank rods. Under seat pulley with control lever is arranged for boat travel direction control.

EFFECT: enabling expansion of functional capabilities and improvement of pedal drive characteristics.
