摘要： A golf taining device is mounted on the bill of a golfer's headpiece and is operable to provide clear evidence of improper head or neck movement during the golf swing, and foster coordinated rotational movement of shoulders, torso and hips. The device includes a ball and a base member consisting of a cup shaped ball carrying seat structure having a ball retaining wall having side walls of a reduced height but of a size and disposition to normally keep the ball in the seat structure even during the address of a ball to be struck and during a correct swing. The ball is tethered to the base member by a flexible cord and the wall is of insufficient size to prevent movement of the ball out of the seat structure when the base member is moved or tilted in an accented way by improper head or neck movement during the golf swing. When the ball moves out of the seat structure it falls by gravity to dangle in front of the golfer's eyes to provide a clear indication of improper head or neck movement, including related improper shoulder, torso or hip rotational action.
摘要翻译：一个高尔夫球洗衣装置安装在高尔夫球手的头盔的帐单上，可操作以提供高尔夫挥杆期间不正确的头部或颈部运动的明确证据，并促进肩部，躯干和臀部的协调的旋转运动。该装置包括一个球体和一个基座部件，该基座部件由具有座椅结构的杯形球构成，该座椅结构具有球形挡土墙，球形挡土墙的侧壁具有减小的高度，但尺寸和布局通常将球保持在座椅结构中，即使在一个被击中的球和正确的摆动。球通过柔性绳索系在基座构件上，并且壁的尺寸不足以防止当基座构件以不规则的头部或颈部移动方式移动或倾斜时，球从球座结构移动高尔夫挥杆。当球从座椅结构中移出时，重力会因高尔夫球手的眼睛前倾而下降，以提供不正确的头部或颈部运动的明显指示，包括相关的不正确的肩部，躯干或髋部旋转动作。
