Abstract

The invention generally relates to hand-held underwater propulsion systems. In certain embodiments, systems of the invention include a hand-held body having a water-tight compartment. There is a motor housed within the water-tight compartment. There are a plurality of propeller blades located at a front portion of the body and coupled to the motor. Each blade includes a retracted configuration and a deployed configuration, and in the deployed configuration, the blades are biased away from the body.

Claims (23)

1. A hand-held underwater propulsion system, the hand-held underwater propulsion system comprising:

a body comprising a water-tight compartment and a handle that extends from the body;

a motor housed within the water-tight compartment; and

a plurality of propeller blades located at a front portion of the body and coupled to the motor, each of the plurality of propeller blades comprising a retracted configuration and a deployed configuration, wherein in the deployed configuration, the plurality of propeller blades are biased away from the body;

wherein the hand-held underwater propulsion system is configured such that when in operation, the hand-held underwater propulsion system pulls a user through the water.

2. The hand-held underwater propulsion system according to claim 1 , wherein the body is configured to hold the plurality of propeller blades in the retracted configuration within the body.

3. The hand-held underwater propulsion system according to claim 2 , wherein when the plurality of propeller blades are retracted within the body, the body is cylindrically shaped.

4. The hand-held underwater propulsion system according to claim 1 , wherein the body is configured to hold the plurality of propeller blades in the retracted configuration against an outer surface of the body.

5. The hand-held underwater propulsion system according to claim 4 , wherein the outer surface of the body comprises a recessed portion for each of the plurality of propeller blades in the retracted configuration.

6. The hand-held underwater propulsion system according to claim 1 , wherein the hand-held underwater propulsion system comprises three blades.

7. The hand-held underwater propulsion system according to claim 1 , wherein the plurality of propeller blades are hingedly connected to the body.

8. The hand-held underwater propulsion system according to claim 1 , further comprising a control board within the water-tight compartment.

9. The hand-held underwater propulsion system according to 8 , wherein the control board allows for a plurality of different propeller speeds.

10. The hand-held underwater propulsion system according to claim 1 , further comprising a trigger along an external portion of the body that is operably coupled to the hand-held underwater propulsion system.

11. The hand-held underwater propulsion system according to claim 10 , wherein compression of the trigger deploys the plurality of propeller blades from the retracted configuration to the deployed configuration and initiates the motor.

12. The hand-held underwater propulsion system according to claim 1 , wherein a front end of the body comprises a cone.

13. The hand-held underwater propulsion system according to claim 1 , further comprising a power supply configured to fit within the water-tight compartment.

14. The hand-held underwater propulsion system according to claim 13 , wherein the power supply is a lithium ion battery.

15. The hand-held underwater propulsion system according to claim 1 , further comprising an external battery pack operably coupled to the hand-held underwater propulsion system.

16. The hand-held underwater propulsion system according to claim 1 , further comprising a mechanism that actively ejects the blades from the retracted configuration to the deployed configuration.

17. The hand-held underwater propulsion system according to claim 16 , wherein the mechanism is a spring-based mechanism.

18. The hand-held underwater propulsion system according to claim 1 , further comprising a light operably coupled to the body.

19. The system according to claim 1 , further comprising a fin, the fin having a retracted configuration and a deployed configuration.
