    • A swing weight scale is presented that measures the swing weight of a golf club by measuring the torque exerted by the club about fixed balance point. The apparatus comprises an elongated torque arm pivotally mounted to a base. At one end of the torque arm a pair of rollers cradle the shaft of the golf club from underneath. At the other end of the torque arm a vertical stop provides a reference for locating the butt of the golf club shaft and provides the mounting surface for a second pair of rollers that cradle the upper surface of the shaft at the butt end. The rollers allow the golf club shaft to freely rotate about its longitudinal axis so that the golf club head will hang down freely. A torque sensor is mounted at the pivot point of the torque arm to measure the torque produced by the golf club as it is supported by the torque arm. A simple computer program converts the torque produced by the golf club on the torque arm into swing weights based on the known dimensions, weight and other parameters of the apparatus.
    • 提出了一种摆动重量级,其通过测量由球杆施加的关于固定平衡点的扭矩来测量高尔夫球杆的摆动重量。 该装置包括可枢转地安装到基座的细长扭矩臂。 在扭矩臂的一端,一对滚子从下面摇动高尔夫球杆的轴。 在扭矩臂的另一端,垂直挡块提供用于定位高尔夫球杆杆的对接的参考,并为第二对辊提供安装表面,第二对辊在对接端处支撑轴的上表面。 滚子允许高尔夫球杆杆绕其纵向轴线自由旋转,使得高尔夫球杆头部将自由地下垂。 转矩传感器安装在转矩臂的枢转点处,以测量由转矩臂支撑的高尔夫球杆产生的扭矩。 简单的计算机程序根据装置的已知尺寸,重量和其他参数,将由转矩臂上的高尔夫球杆产生的扭矩转换成摆锤。

    • A gauge for measuring the loft and lie angles of a golf club includes a rod attachable to the golf club with a first pointer mechanism being in alignment with the shaft axis of the golf club. A body is rotatable about the rod into parallel alignment with the sole of the golf club and a first indicator plate is movable with the body and relative to the first pointer mechanism to provide a visual indication of the lie angle of the golf club by showing the angle of rotation of the indicator plate relative to the first pointer mechanism. A face engaging member is pivotally mounted on the body for movement into engagement with the face of the golf club, and a second pointer mechanism is movable with the face engaging member relative to a second indicator plate carried on the body to provide a visual indication of the loft angle of the golf club by showing the angle of rotation of the second pointer mechanism relative to the second indicator plate.
    • 用于测量高尔夫球杆的高度和俯角的测量器包括可附接到高尔夫球杆的杆,第一指针机构与高尔夫球杆的轴线对准。 身体可以围绕杆旋转,与高尔夫球杆的鞋底平行对准,并且第一指示板可以与身体相对于第一指针机构移动,以通过显示高尔夫球杆的角度来提供高尔夫球杆的躺角的视觉指示 指示板相对于第一指针机构的旋转角度。 面接合构件枢转地安装在主体上用于与高尔夫球杆的表面相接合,并且第二指针机构可与面接合构件相对于承载在身体上的第二指示板移动以提供视觉指示 通过示出第二指示器机构相对于第二指示器板的旋转角度,高尔夫球杆的倾斜角度。
