Sportsball with Weight Control Arrangement

Abstract

A sportsball includes a ball cover having a spherical ball cavity, an inflatable ball bladder disposed in the ball cavity of the ball cover; and a weight control arrangement which includes a plurality of weight panels. The weight panels are made of the same material of the ball bladder and are attached to the ball bladder for not only controlling a weight of the ball bladder but also strengthening the ball bladder to support the ball cover after the ball bladder is inflated.

         5 . The sportsball, as recited in  claim 1 , wherein said weight panels are adhered to an inner surface of said ball bladder. 
     
     
         6 . The sportsball, as recited in  claim 2 , wherein said weight panels are adhered to an inner surface of said ball bladder. 
     
     
         7 . The sportsball, as recited in  claim 1 , wherein said weight panels are integrally formed edge-to-edge to form an outer bladder which is integrally attached to an outer surface of said ball bladder. 
     
     
         8 . The sportsball, as recited in  claim 2 , wherein said weight panels are integrally formed edge-to-edge to form an outer bladder which is integrally attached to an outer surface of said ball bladder. 
     
     
         9 . The sportsball, as recited in  claim 4 , wherein said weight panels have the same uniform thickness, wherein said thickness of each of said weight panel is equal or smaller than a thickness of said ball bladder. 
     
     
         10 . The sportsball, as recited in  claim 6 , wherein said weight panels have the same uniform thickness, wherein said thickness of each of said weight panel is equal or smaller than a thickness of said ball bladder. 
     
     
         11 . The sportsball, as recited in  claim 8 , wherein said weight panels have the same uniform thickness, wherein said thickness of each of said weight panel is equal or smaller than a thickness of said ball bladder. 
     
     
         12 . The sportsball, as recited in  claim 9 , wherein said valve stem is extended through one of said weight panels to secure said valve stem in position. 
     
     
         13 . The sportsball, as recited in  claim 10 , wherein said valve stem is extended through one of said weight panels to secure said valve stem in position. 
     
     
         14 . The sportsball, as recited in  claim 11 , wherein said valve stem is extended through one of said weight panels to secure said valve stem in position. 
     
     
         15 . The sportsball, as recited in  claim 12 , wherein each of said weight panels has an elliptical shape. 
     
     
         16 . The sportsball, as recited in  claim 13 , wherein each of said weight panels has an elliptical shape. 
     
     
         17 . The sportsball, as recited in  claim 14 , wherein each of said weight panels has an elliptical shape. 
     
     
         18 . A method of manufacturing a sportsball, which requires a specify weight requirement, comprising the steps of:
 (a) forming a ball cover having a spherical ball cavity, wherein said ball cover is formed by the steps of:   (a.1) forming an outer cover panel, a single inner lining, and a cushioning laver, wherein said inner lining is a fabric layer knitted to have the same tension at longitudinal and transverse directions so as to reduce a weight of said ball cover and to ensure a strength said ball cover; and   (a.2) integrally bonding said cushioning layer between said outer cover panel and said inner lining to form said ball cover;   (b) forming an inflatable ball bladder which has a valve stem formed thereat;   (c) forming a plurality of weight panels which are made of the same material of said ball bladder;   (d) symmetrically attaching said weight panels to said ball bladder for not only controlling a weight of said ball bladder when the weight of said ball cover is reduced but also strengthening said ball bladder to prevent said ball cover being over-inflated, wherein said weight panels are selectively configured to add the weight of said inflatable ball bladder to ensure said sportsball to meet the specify weight requirement; and   (e) disposing said ball bladder with said weight panels in said ball cavity of said ball cover to support said ball cover after said ball bladder is inflated.   
     
     
         19 . The method as recited in  claim 18  wherein, in the step (d), said weight panels are integrally attached to an outer surface of said ball bladder. 
     
     
         20 . The method as recited in  claim 18  wherein, in the step (d), said weight panels are adhered to an inner surface of said ball bladder. 
     
     
         21 . The method as recited in  claim 18  wherein, in the step (d), said weight panels are integrally formed edge-to-edge to form an outer bladder which is integrally attached to an outer surface of said ball bladder. 
     
     
         22 . The method as recited in  claim 18  wherein, in the step (c), said weight panels are formed to have the same uniform thickness, wherein said thickness of each of said weight panel is equal or smaller than a thickness of said ball bladder. 
     
     
         23 . The method as recited in  claim 18  wherein, in the step (d), said valve stem is extended through one of said weight panels to secure said valve stem in position. 
     
     
         24 . The method, as recited in  claim 18 , wherein each of said weight panels has an elliptical shape.
