发明名称 GOLF BALL TEE
摘要 A reusable golf ball tee of plastic material that renders it practically indestructible and which is of a shape like a badminton shuttlecock with a relatively wide base that constitutes a skirt in flight to retard forward movement when it is struck by the head of a golf club. The skirt portion of the golf ball tee is perforated to render it of light weight and suitably ribbed to reinforce the same sufficiently to withstand the severe service to which it is exposed. Another feature is an adjustable seat on which the golf ball rests in the form of a tubular member having external spaced grooves that interact with a lip on the skirt member to maintain the different vertical positions that determine the height of the golf ball when it is mounted thereon. Further, the skirt member has a considerable surface area on which advertising copy is printed and thereby they can be furnished free to golfers.
