Abstract

A piece of sports equipment includes a handle, a head attached to the handle, and at least one dead blow mechanism. The at least one dead blow mechanism includes a chamber and a movable portion disposed within the chamber. The chamber and the movable portion each include a similar cross sectional shape.

That which is claimed is: 
     
         1 . A piece of sports equipment comprising:
 a handle;   a head attached to the handle; and   at least one dead blow mechanism,   wherein the at least one dead blow mechanism comprises a chamber and at least one movable portion disposed within the chamber.   
     
     
         2 . The piece of sports equipment of  claim 1 , wherein the chamber and the at least one movable portion each comprise a similar cross sectional shape. 
     
     
         3 . The piece of sports equipment of  claim 1 , wherein the chamber comprises a circular cross section. 
     
     
         4 . The piece of sports equipment of  claim 1 , wherein the at least one movable portion comprises at least one selected from the group of steel, tungsten, aluminum, rubber, graphite, polymer, and lead. 
     
     
         5 . The piece of sports equipment of  claim 1 , wherein the sports equipment is a lacrosse stick. 
     
     
         6 . The piece of sports equipment of  claim 1 , wherein the chamber comprises at least one selected from the group of air, water, oil, and a vacuum. 
     
     
         7 . The piece of sports equipment of  claim 1 , wherein an internal surface of the chamber comprises a coating to reduce friction between the chamber and the at least one movable portion. 
     
     
         8 . The piece of sports equipment of  claim 1 , wherein the at least one dead blow mechanism comprises at least two dead blow mechanisms. 
     
     
         9 . The piece of sports equipment of  claim 1 , wherein the at least one dead blow mechanism is modular and can be tuned by changing at least one selected from the group of weight of the at least one movable portion, size of the at least one movable portion, shape of the at least one movable portion, or quantity of the at least one movable portion. 
     
     
         10 . The piece of sports equipment of  claim 1 , wherein movement of the at least one movable portion comprises at least one selected from the group of linear, a circular arc, a curved path, a partially curved path, or a compound curved path. 
     
     
         11 . A lacrosse stick comprising:
 a handle;   a head attached to the handle; and   at least one dead blow mechanism.   
     
     
         12 . The lacrosse stick of  claim 11 , wherein the at least one dead blow mechanism comprises a chamber and at least one movable portion disposed within the chamber. 
     
     
         13 . The lacrosse stick of  claim 12 , wherein the chamber and the at least one movable portion each comprise a similar cross sectional shape. 
     
     
         14 . The lacrosse stick of  claim 12 , wherein the chamber comprises a circular cross section. 
     
     
         15 . The lacrosse stick of  claim 12 , wherein the at least one movable portion comprises at least one selected from the group of steel, tungsten, aluminum, rubber, graphite, polymer, and lead. 
     
     
         16 . The lacrosse stick of  claim 12 , wherein the chamber comprises at least one selected from the group of air, water, oil, and a vacuum. 
     
     
         17 . The lacrosse stick of  claim 12 , wherein an internal surface of the chamber comprises a coating to reduce friction between the chamber and the at least one movable portion. 
     
     
         18 . The lacrosse stick of  claim 12 , wherein the at least one dead blow mechanism is modular and can be tuned by changing at least one selected from the group of weight of the at least one movable portion, size of the at least one movable portion, shape of the at least one movable portion, or quantity of the at least one movable portion. 
     
     
         19 . The lacrosse stick of  claim 12 , wherein movement of the at least one movable portion comprises at least one selected from the group of linear, a circular arc, a curved path, a partially curved path, or a compound curved path. 
     
     
         20 . The lacrosse stick of  claim 11 , wherein the at least one dead blow mechanism comprises at least two dead blow mechanisms.
