    • Football game for reduced size playing areas, especially indoor playing areas. The invention comprises providing a playing field (10) measuring approximately 198 feet long by 84 feet wide, having markings (75) thereon indicating boundaries, end zones and yardage markers. Two opposing teams, each comprising eight members, attempt to advance a football into the opposing team's end zone to score. The various rules of play of the present invention render it amenable to play in a reduced size setting. In addition to the side and end boundaries of the playing field, overhead boundary surfaces (110a, 110b) may be provided which restrict the height above the playing field to which passed or kicked balls may travel, without striking the upper boundaries and becoming a dead ball. The upper boundary surface may comprise at least one vertically hanging flexible surface, such as a heavy netting, suspended over the central portion of the field.
    • 足球游戏减少游戏区域,特别是室内游乐区。 本发明包括提供测量大约198英尺长×宽84英尺的游戏场(10),其上具有指示边界,端区和码数标记的标记(75)。 两个反对队伍,每个队伍由八名成员组成,试图将足球推进对方队伍的终点区域。 本发明的各种游戏规则使得它可以以缩小的尺寸设置来播放。 除了游戏场的边界和边界之外,还可以提供架空边界面(110a,110b),其限制通过或踢球可以行进的运动场上方的高度,而不会打到上边界并变成死角 球。 上边界表面可以包括悬挂在场的中心部分上的至少一个垂直悬挂的柔性表面,例如大网。

    • An athletic shooting aid adapted to be detachably mounted directly on the goal of a sporting event to provide a target at which the player aims and strikes with the game piece in order to improve the form and the accuracy of the player's shooting. The device (20) comprises a clamp (30) which is removably attachable to the goal having a substantially straight elongated member (50) extending from the clamp (30) with a ball or bulk of material (60) attached to the elongated member (50) to serve as the target at which the player aims when shooting the game piece. The elongated member is adapted and configured to allow the ball (60) to move when struck by the game piece in such a manner that the game piece deflects the ball without substantially affecting the trajectory of the game piece and to allow the ball to be repositioned after the game piece has passed through the goal.
    • 运动型射击辅助装置适于直接安装在体育赛事的目标上,以提供玩家瞄准和击球的目标,以改善玩家射击的形式和准确性。 装置(20)包括可拆卸地附接到目标的夹具(30),所述夹具具有从夹具(30)延伸的基本上直的细长构件(50),所述基本上直的细长构件(50)具有附接到细长构件的球体或块体(60) 50)作为玩家在拍摄游戏片时瞄准的目标。 细长构件适于和构造成允许球(60)以游戏件撞击时移动,使得游戏件偏转球而基本上不影响游戏件的轨迹并允许球重新定位 游戏完成后通过目标。

    • A football (10) having external fins (15a, 15b) mounted on opposite sides thereof which are configured to promote rotation of the football (10) about its longitudinal axis (13). Each of the fins (15a, 15b) is configured as an airfoil having an upper surface (20) and a lower surface (22), with the understanding that the upper surface (20) represents the direction of the lift. Each fin (15a, 15b) is oriented to form a helical pitch angle of at least 15 degrees. The leading (17) and trailing (18) edges of the fins (15a, 15b) are longitudinally positioned such that the net center of aerodynamic lift of the fins (15a, 15b) is located aft of the longitudinal midpoint of the football (10) in order to promote stability in flight.
    • 具有安装在其相对侧上的外部翅片(15a,15b)的足球(10),其构造成促进足球(10)围绕其纵向轴线(13)旋转。 每个翅片(15a,15b)被构造为具有上表面(20)和下表面(22)的翼型,其理解是上表面(20)表示升力的方向。 每个翅片(15a,15b)被定向成形成至少15度的螺旋桨距角。 翼片(15a,15b)的前缘(17)和后缘(18)的边缘被纵向定位成使得翅片(15a,15b)的空气动力提升的净中心位于足球的纵向中点(10 ),以促进飞行中的稳定。
