    • A hollow golf club is provided having an outer shell and an inner frame. The outer shell comprises one or more lightweight members, such as the crown or the skirt, and preferably fits within an envelope of about 5 inches×5 inches×2.8 inches. The inner frame fits within a smaller envelope and sits on the sole of the club head. One or more weights are located either on or within the inner frame to optimize the moment of inertia of the club head about both the vertical axis running through the center of gravity or geometric center of the club head, hereinafter referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, hereinafter referred to as the “hosel axis.” The weights can be attached to the inner frame or can be distributed within the inner frame. In another embodiment, the hitting face and a portion of the skirt proximate the toe form a curved blade in the shape of a sickle or battle ax and an inner support bridges the toe end of the curved blade to the hosel for structural support. The ratio of moment of inertia of the club head about the y-axis to moment of inertia of the club head about the hosel axis is preferably 0.55. More preferably, this ratio is 0.75.
    • 提供具有外壳和内框架的空心高尔夫球杆。 外壳包括一个或多个轻质构件,例如冠部或裙部,并且优选地配合在约5英寸×5英寸×2.5英寸的封套内。 内框架位于较小的信封内,并且位于球杆头的底部。 一个或多个重物位于内框架上或内框架上,以优化球杆头围绕穿过重心或垂直于球杆头的几何中心的垂直轴线的惯性矩,以下称为“ 轴“,并且轴穿过高尔夫球杆的轴的中心,以下称为”插鞘轴“。 重物可以附接到内框架上,或者可以分配在内框架内。 在另一个实施例中,撞击面和靠近脚趾的裙部的一部分形成镰刀或战斧形状的弯曲刀片,并且内部支撑件将弯曲刀片的脚趾端部连接到插鞘以进行结构支撑。 球棒头围绕y轴的惯性矩与球杆头围绕插鞘轴的惯性矩的比率优选为0.55。 更优选地,该比例为0.75。
