发明名称 Golf putting/chipping instructional device and method of use
摘要 The present invention relates to a golf instructional device for assisting a golfer to putt/chip a golf ball to a golf hole. The device includes a substantially rigid body formed to visually identify a point of entry adjacent the golf hole and a breaking point on a line of travel. The body may define an intermediate guideline member having a generally u-shaped configuration formed to surround at least a portion of the golf hole, and elongated first and second guideline members extending from a portion of the intermediate guideline member which define first and second boundaries for the point of entry respectively. At least a portion of the intermediate guideline member is positionable adjacent the golf hole and rotatable thereabout so as to allow the first and second guideline members to collectively define the first and second boundaries for the point of entry and for identifying the breaking point.
