推杆练习辅助工具
摘要：
本发明涉及一种带有框架(16)的推杆练习辅助工具(10)，该框架(16)安装有灯光单元(18)以把高尔夫球洞映像照在地面上。框架(16)安装在两个底座(14)上，两个底座(14)中的一个包含光束发射器(30)以生成红外光束(34)，以球洞映像为目标的高尔夫球会穿过该光束，而另一个包含相对应的光束接收器(32)。高尔夫球隔断由发射器(30)所产生的相应的光束(34)的时刻和时间长短用来确定以映像光环(28)为目标的击球的结果，以提示球是否可以在该点进入真正的高尔夫球洞，并且这由听觉信息来传达。
摘要（英）：

A putting practice aid (10) with a frame (16) which mounts a light unit (18) to shine the image of a golf hole on the ground. The frame (16) is mounted on two feet (14) one of which contains beam transmitters (30) producing infra red beams (34) which will be crossed by a golf ball aimed at the illumination of the hole, and the other contains respective corresponding beam receivers (32). The timing and duration of the break caused by a golf ball of the respective beams (34) produced by the transmitters (30) is used to determine the outcome of a shot aimed at the illuminated circle (28) to indicate whether the ball would have entered a real golf hole at this point, and this is communicated by an audible message.
