    • A football comprising an inflatable bladder integrally molded with raised areas which are intended to be exposed, and exterior panels which are adhered to the bladder to span the spaces between them. The raised areas or ridges are formed to extend outward from the exterior panels and provide a raised grip area. By bonding the exterior panels to the bladder directly, stitching and lacing are eliminated to simplify construction and manufacture. The football is provided with a plurality of raised areas to provide more grip areas than the single lace area of a traditional football. Each of the raised ridges are contoured to more closely follow the shape of a thrower's hand as it grasps the ball and thereby providing greater contact area and better control.
    • 一种足球,其包括一个可膨胀的气囊,其一体地模制有待暴露的凸起区域,以及外部面板,其粘附到膀胱以跨越它们之间的空间。 凸起区域或凸起形成为从外部面板向外延伸并提供凸起的抓握区域。 通过将外部面板直接粘合到气囊上,可以消除缝合和缝合,从而简化结构和制造。 足球设置有多个凸起区域以提供比传统足球的单个花边区域更多的抓地力区域。 每个凸脊的轮廓都被轮廓化,以更紧密地跟随抛出者的手的形状,因为它抓住球,从而提供更大的接触面积和更好的控制。
