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.
Claims24
A sportsball, which requires a specify weight requirement, comprising:
- a ball cover having a spherical ball cavity, and comprising an outer cover panel, a single inner lining, and a cushioning layer integrally bonded between said outer cover panel and said inner lining, wherein said inner lining is a fabric layer knitted to have the same tension at longitudinal and transverse directions to reduce a weight of said ball cover and to ensure a strength said ball cover;
- an inflatable ball bladder disposed in said ball cavity of said ball cover, wherein said ball bladder has a valve stem formed thereat for inflating said ball bladder;
- and
- a weight control arrangement, comprising a plurality of weight panels which are made of the same material of said ball bladder and are attached 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 support said ball cover after said ball bladder is 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.
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.
