  • Patent number: 7052416
    Abstract: A golf range tee includes a hollow supporting frame and a retention arrangement. The supporting frame has an upper end and a lower end, and defining a holding channel extending from the upper end towards the lower end for a shaft of the golf tee to slidably insert into the holding channel so as to selectively adjust a height a cup of the golf tee with respect to the ground. The retention arrangement has a sliding slot radially formed at the supporting frame from the upper end thereof to communicate the holding channel with an exterior of the supporting frame. Therefore, when an impact force is applied at the golf tee, the golf tee is forced to slide from the holding channel through the sliding slot so as to distribute the impact force at the golf tee to prevent the golf tee from being broken.
