Abstract

Disclosed is a self-propelled football with an internally ducted fan and electric motor. An exemplary embodiment has an oblate spheroidal body. The body has a front section, a center section, a back section, and a longitudinal axis. The ducted fan is located within the body substantially within the center section and substantially along the longitudinal axis. The electric motor is located within the body and mechanically coupled to the ducted fan. At least one electrical power source is located within the body and electrically coupled to the electric motor. At least one air-inlet is located within the front section of the body in airflow communication with the ducted fan. At least one air-outlet is located within the back section of the body in airflow communication with the ducted fan. A means for automatic activation and deactivation of the electrical motor is located within the body.

Claims

1. A self-propelled flying toy with an automatic activation and deactivation mechanism, comprising:

a flying toy body defined as comprising a longitudinal axis;

a motor attached to the body;

a ducted fan mechanically coupled to the motor and substantially centered about the longitudinal axis;

a power source energetically coupled to the motor; and

a centrifugal switch in communication with the motor and power source, the centrifugal switch controllably turning the motor on and powering the ducted fan when rotation about the longitudinal axis is detected during a throw and turning the motor off and not powering the ducted fan when rotation about the longitudinal axis is not detected when not being thrown.

2. The automatic activation and deactivation mechanism of claim 1, further including a timer attached to the body in communication with the motor and the power source, wherein the motor, after activation, will automatically turn off after a predetermined time.

3. The automatic activation and deactivation mechanism of claim 2, wherein the motor comprises an electric motor.

4. The automatic activation and deactivation mechanism of claim 3, wherein the power source comprises an electric power source.

5. The automatic activation and deactivation mechanism of claim 4, further including a low voltage cutoff located within the body in electrical communication with the electrical motor and the electrical power source, wherein once the voltage from the electrical power source drops below a predetermined level, voltage supplied to the electrical motor is severed.

6. The automatic activation and deactivation mechanism of claim 5, wherein the centrifugal switch comprises at least one hollow chamber attached to the body substantially perpendicular to the longitudinal axis with an electrical circuit gap disposed at a distal end of the at least one hollow chamber in electrical communication with electrical motor and electrical power source and further including at least one conductive mass located within the at least one hollow chamber, wherein centrifugal forces imparted to the at least one conductive mass during rotation about the longitudinal axis move the conductive mass in contact with the electrical circuit gap thereby activating the electrical motor.

7. The automatic activation and deactivation mechanism of claim 5, wherein the centrifugal switch comprises a lever switch attached to the body in electrical communication with the electrical power source and electric motor.

8. The automatic activation and deactivation mechanism of claim 5, wherein the centrifugal switch comprises at least one hollow chamber attached to the body substantially perpendicular to the longitudinal axis with a reed switch disposed at a distal end of the at least one hollow chamber in electrical communication with the electrical motor and electrical power source, and further including a permanent magnet located within the at least one hollow chamber, wherein centrifugal forces imparted to the permanent magnet during rotation about the longitudinal axis move the permanent magnet closer to the reed switch thereby activating the reed switch through a magnetic field imparted by the permanent magnet and thereby activating the electrical motor.

9. The automatic activation and deactivation mechanism of claim 5, wherein the centrifugal switch comprises a microcontroller attached to the body in electrical communication with the electrical power source and electric motor, wherein the microcontroller can detect when the self-propelled flying toy is being thrown and caught and can automatically activate and deactivate the electrical motor.

10. The automatic activation and deactivation mechanism of claim 5, wherein the centrifugal switch comprises at least one accelerometer attached to the body and further including a microcontroller attached to the body, wherein the microcontroller is in electrical communication with the at least one accelerometer, the electrical power source, and the electric motor.

11. The automatic activation and deactivation mechanism of claim 5, wherein the flying toy body comprises a football shaped body or an oblate spheroidal shaped body.

12. A user-launched self-propelled flying toy with an automatic activation and deactivation mechanism, comprising:

a body of a flying toy defined as comprising a longitudinal axis of rotation;

an electric motor fixed relative to the body;

a ducted fan mechanically coupled to the electric motor and substantially centered about the longitudinal axis of rotation;

an electrical power source electrically coupled to the electric motor; and

a centrifugal switch in communication with the electric motor and electric power source, the centrifugal switch controllably turning the electric motor on and powering the ducted fan when rotation about the longitudinal axis of rotation is detected during a throw and turning the electric motor off and not powering the ducted fan when rotation about the longitudinal axis of rotation is not detected when not being thrown.

13. The automatic activation and deactivation mechanism of claim 12, further including a timer attached to the body in communication with the electric motor and the electrical power source, wherein the electrical motor, after activation, will automatically turn off after a predetermined time.

14. The automatic activation and deactivation mechanism of claim 13, further including a low voltage cutoff located within the body in electrical communication with the electrical motor and the electrical power source, wherein once the voltage from the electrical power source drops below a predetermined level, voltage supplied to the electrical motor is severed.

15. The automatic activation and deactivation mechanism of claim 14, further including at least one air-inlet disposed along the body having airflow communication with the ducted fan.

16. The automatic activation and deactivation mechanism of claim 15, further including at least one air-outlet disposed along the body having airflow communication with the ducted fan.

17. A self-propelled flying toy, comprising:

a body defined as comprising a longitudinal axis;

a ducted fan disposed within the body substantially centered about the longitudinal axis;

an electric motor mechanically coupled to the ducted fan and fixed relative to the body;

at least one electrical power source electrically coupled to the electric motor;

an air-inlet disposed along the body having airflow communication with the ducted fan;

an air-outlet disposed along the body having airflow communication with the ducted fan; and

a centrifugal switch in electrical communication with the electric motor and the at least one electric power source, the centrifugal switch controllably turning the electric motor on and powering the ducted fan when rotation about the longitudinal axis is detected during a throw and turning the electric motor off and not powering the ducted fan when rotation about the longitudinal axis is not detected when not being thrown.

18. The self-propelled flying toy of claim 17, further including a timer located within the body in electrical communication with the electrical motor and the electrical power source, wherein the electrical motor, after activation, will automatically turn off after a predetermined time.
