Pitch Training Device With Adjusted Center of Mass

Abstract

A device for training a person to throw a ball includes a body. The body defines a first planar surface, a second planar surface, and a curved surface. The first planar surface is defined at a first end of the body. The second planar surface is defined at a second end of the body. The curved surface is defined between the first planar surface and second planar surface. The device has a center of mass that is located outside of the geometric center of the device.

What is claimed is: 
     
         1 . A device for training a person to throw a ball, the device comprising:
 a body, the body defining
 a first planar surface at a first end of the body and a second planar surface at a second end of the body; and 
 a curved surface disposed between the first planar surface and second planar surface, wherein
 the device has a center of mass that is located outside of the geometric center of the device. 
 
   
     
     
         2 . The device of  claim 1 , further comprising:
 a core that is a solid and that is disposed within the body.   
     
     
         3 . The device of  claim 1 , wherein the body is made up of two half-bodies, each half body defining part of a void that accommodates the core therein, the void accommodating the core outside of the geometric center of the device. 
     
     
         4 . The ball of  claim 3 , wherein
 each half-body defines a scaffolded interior that surrounds the core, the scaffolded interior having a plurality of openings within the scaffolding; and   at least one weight is disposed in at least one of the openings within the scaffolding.   
     
     
         5 . The device of  claim 4 , wherein the at least one weight is a ball bearing. 
     
     
         6 . The device of  claim 4 , wherein the at least one weight is a solid at room temperature and is made of a metal or a metal alloy. 
     
     
         7 . The device of  claim 4 , wherein the at least one weight is a liquid at room temperature. 
     
     
         8 . The device of  claim 3 , wherein a first of the two half-bodies contains more mass than a second of the two half-bodies. 
     
     
         9 . The device of  claim 1 , further comprising:
 a disk that is coupled to either the first or second planar surface.   
     
     
         10 . The device of  claim 9 , wherein the disk has a mass between 5 g and 100 g. 
     
     
         11 . A pitch training apparatus, wherein the apparatus further comprises:
 a body, the body defining
 a first planar surface at a first end of the body and a second planar surface at a second end of the body, and 
 a curved surface disposed between the first planar surface and second planar surface, wherein
 the device has a center of mass that is located outside of the geometric center of the device; 
 
   at least one processor;   at least one sensor; and   at least one memory storing computer instructions, which when executed by the at least one processor cause the apparatus to record information related to a movement and a position of the pitch training apparatus.
