    • A game ball having a high end synthetic leather cover formed from a non-woven fiber mat impregnated with polyurethane. In one embodiment, the game ball is a football and the fibers in the backing of the cover material have a denier of about 0.1 or less. In another embodiment, the game ball cover has a dual layer coating to impart to the cover good pebble retention. The first layer has a Shore A hardness of at least about 65, and the second layer surrounding the first layer has a Shore A hardness lower than the hardness of the first layer. The game ball, which can be formed to meet association specifications, has properties of softness and durability comparable to those of a genuine full grain leather game ball.
    • 具有由浸渍有聚氨酯的无纺纤维垫形成的高端合成皮革罩的游戏球。 在一个实施例中,游戏球是足球,并且覆盖材料的背衬中的纤维的旦数为约0.1或更小。 在另一个实施例中,游戏球罩具有双层涂层以赋予盖更好的卵石保持力。 第一层具有至少约65的肖氏A硬度,围绕第一层的第二层的肖氏A硬度低于第一层的硬度。 可以形成以满足协会规格的游戏球具有与真正全粒皮革游戏球相当的柔软性和耐久性的性质。

    • An improved American football comprising an inflatable, one piece bladder formed in a generally elliptical shape and fabricated of an elastomeric material; four panels secured together over the bladder, each panel being of a similar, generally oval shape with inturned edges secured together by stitching to form four seams; an essentially inextensible liner formed of four liner components, each liner component being of a similar, generally oval shape with inturned edges secured together and to an associated panel by stitching to form four seams, the liner components being located between the panels and the bladder, an opening formed centrally along a part of one seam at a location where the panels and liner components are not stitched; lacing located along the opening to couple the inturned edges in place of the stitching; closure means comprising two patches and a tongue located between the bladder and liner components, the patches being stitched to the liner components, the patches being stitched to the liner components and panels on opposite sides of the opening, the tongue being stitched to a liner component and panels and extending to a location between the bladder and patches; and a counter weight of a high density elastomeric material, and of a weight substantially equal to that of the lacing and closure means and molded to the bladder externally thereof along the seam of the panels opposite the lacing.
    • 一种改进的美式足球,其包括形成为大致椭圆形并且由弹性体材料制成的可膨胀的单件式气囊; 四个面板固定在膀胱上,每个面板具有相似的,大致椭圆形的形状,其中内侧的边缘通过缝合固定在一起以形成四个接缝; 由四个衬垫部件形成的基本上不可伸展的衬套,每个衬垫部件具有相似的,大致椭圆形的形状,其内侧边缘固定在一起,并通过缝合形成相关联的面板以形成四个接缝,衬套部件位于面板和囊之间, 沿着一个接缝的一部分中心地在面板和衬垫部件未缝合的位置处形成的开口; 缝合位于开口处,以连接内翻边缘以代替缝合; 封闭装置包括两个贴片和位于囊和衬垫部件之间的舌片,所述贴片被缝合到衬垫部件上,所述贴片被缝合到衬垫部件和面板在开口的相对侧上,舌部被缝合到衬垫部件 和面板并延伸到膀胱和贴片之间的位置; 和高密度弹性体材料的配重,其重量基本上等于系带和闭合装置的重量,并且沿着与鞋带相对的面板的接缝在外部模制到其外部。
