Abstract
An underwater propulsion system is disclosed comprising a foot board with one or more battery-powered propulsion units. A throttle control system may be enabled in the foot board such that a movement of the user's foot controls the throttle. Flattened Lithium batteries allow thin lightweight construction of the foot board. Use of trolling motors as propulsion units provides thrust advantages over pre-existing underwater scooters.
Claims6
An underwater propulsion device comprising:
- (a) a foot board;
- (b) a battery sealed in a watertight compartment that is integrated with said foot board;
- (c) wherein said foot board has a surface with two attachment structures, one for each of said user's feet;
- (d) wherein two battery-powered underwater propulsion units are mounted on opposite outer sides of said foot board adjacent to the outer sides of each of said user's feet;
- (e) a throttle control system integrated with said foot board that allows the throttle of said propulsion unit to be controlled by a swivel movement of said user's foot, wherein at least one of said foot attachment structures comprises a foot pedal mount that fixes one end of said user's foot to said foot board about a rotational axis that allows the opposite end of said user's foot to swivel from side to side;
- and wherein said throttle control system further includes a tensioned return which tends to bring said user's foot to neutral position when said user does not exert any swivel force with their foot.
