Abstract

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

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A sport training ball for use underwater comprising:
 a resilient spherical body;   an internal chamber positioned within the resilient spherical body and configured to receive a low-density medium having a density less than water; and   a buoyancy reduction device positioned within the resilient spherical body and configured to have a density greater than or equal to water.   
     
     
         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 and configured to receive a low-density medium having a density less than water; and   a buoyancy reduction device positioned within the resilient spherical body and configured to have a density greater than or equal to water;   wherein the buoyancy reduction device is constructed of a high-density material having a density at least equal to water.   
     
     
         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 and configured to receive a low-density medium having a density less than water; and   a buoyancy reduction device positioned within the resilient spherical body and configured to have a density greater than or equal to water, wherein the buoyancy reduction device is constructed of a high-density material having a density at least equal to water;   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.
