Pitching Rubber

Abstract

The present invention is directed to pitching rubbers for baseball. More particularly, the invention relates to a four-sided, solid pitching rubber which provides an all-in-one durable construction with improved performance characteristics. Included in embodiments is a pitching rubber comprising: a solid rubber body with four rectangular sides and two elongated ends; having a surface area of about 648 in 2 to about 744 in 2 ; and having a density ranging from about 0.04 to about 0.06 pounds per cubic inch. A preferred pitching rubber further has a void in each of the elongated ends, which voids together comprise a volume of less than 15% of the volume of the solid rubber body. Pitching rubbers according to embodiments of the invention are capable of resisting packing and tamping weight without deformation of the rubber body.

1 . A pitching rubber comprising:
 a solid rubber body with four rectangular sides and two elongated ends;   having a surface area of about 648 in 2  to about 744 in 2 ; and   having a density ranging from about 0.04 to about 0.06 pounds per cubic inch.   
     
     
         2 . The pitching rubber of  claim 1 , having a void in each of the elongated ends, which voids together comprise a volume of less than 15% of the volume of the solid rubber body. 
     
     
         3 . The pitching rubber of  claim 1 , wherein the solid rubber body resists packing and tamping weight without deformation of the body.
