Abstract

A sport training ball for use underwater includes a resilient spherical body. An internal chamber may be positioned within the resilient spherical body and configured to receive a low-density medium having a density less than water. A second internal chamber may be positioned within the resilient spherical body and configured to receive the low-density medium. A buoyancy reduction device may be positioned within the resilient spherical body and configured to have a density greater than or equal to water.

Claims

1. A sport training ball for use underwater comprising:

a resilient spherical body;

an internal chamber positioned within the resilient spherical body with a low-density medium having a density less than water;

a second internal chamber positioned within the resilient spherical body with the low-density medium; and

a buoyancy reduction device positioned within the resilient spherical body with a liquid high-density medium at least equal to water, wherein each of the internal chamber, the second internal chamber, and the buoyancy reduction device are spherical in shape.

2. The sport training ball of claim 1 wherein the quantity of the low density medium is adjustable to control the overall buoyancy of the sport training ball.

3. The sport training ball of claim 2 wherein the low density medium is air.

4. The sport training ball of claim 1 wherein the buoyancy reduction device is constructed of a high-density material having a density at least equal to water.

5. The sport training ball of claim 4 wherein the high-density material is rubber.

6. The sport training ball of claim 4 wherein the buoyancy reduction device is configured to receive a high-density material having a density at least equal to water.

7. The sport training ball of claim 6 wherein the quantity of the high-density material is adjustable to control the overall buoyancy of the sport training ball.

8. The sport training ball of claim 6 wherein the high-density material is water.

9. The sport training ball of claim 1 wherein the resilient spherical body is constructed, at least in part, of rubber.

10. The sport training ball of claim 1 wherein the resilient spherical body is constructed, at least in part, of leather.

11. The sport training ball of claim 1 wherein the sport training ball is a basketball.

12. A sport training basketball for use underwater comprising:

a resilient spherical body;

an internal chamber positioned within the resilient spherical body with a low-density medium having a density less than water;

a second internal chamber positioned within the resilient spherical body with the low-density medium; and

a buoyancy reduction device positioned within the resilient spherical body with a liquid high-density medium at least equal to water;

wherein the buoyancy reduction device is constructed of a high-density material having a density at least equal to water, and wherein each of the internal chamber, the second internal chamber, and the buoyancy reduction device are spherical in shape.

13. The sport training ball of claim 12 wherein the quantity of the low density medium is adjustable to control the overall buoyancy of the sport training ball.

14. The sport training ball of claim 13 wherein the low density medium is air.

15. The sport training ball of claim 12 wherein the high-density material is rubber.

16. The sport training ball of claim 12 wherein the resilient spherical body is constructed, at least in part, of rubber.

17. The sport training ball of claim 12 wherein the resilient spherical body is constructed, at least in part, of leather.

18. A sport training basketball for use underwater comprising:

a resilient spherical body constructed, at least in part, of rubber;

an internal chamber positioned within the resilient spherical body with a low-density medium having a density less than water;

a second internal chamber positioned within the resilient spherical body with the low-density medium; and

a buoyancy reduction device positioned within the resilient spherical body with a liquid high-density medium at least equal to water, wherein the buoyancy reduction device is constructed of a high-density material having a density at least equal to water, and wherein each of the internal chamber, the second internal chamber, and the buoyancy reduction device are spherical in shape;

wherein the low density medium is air.

19. The sport training ball of claim 18 wherein the quantity of the low density medium is adjustable to control the overall buoyancy of the sport training ball.

20. The sport training ball of claim 18 wherein the high-density material is rubber.
