  • Publication number: 20060052180
    Abstract: An oversize golf club driver head has the maximum legal face dimensions, a loft of at least 17 degrees and a ratio of club depth to face depth that is less than 1.5. This unconventional combination of driver parameters is designed to make it easier for beginning golfers and less skilled golfers to reliably hit a golf ball from a golf tee and thereby give such golfers more confidence in their ability to hit a golf driver. Nevertheless, it results in a golf club driver head configuration which complies with USGA rules and is not peculiar in appearance.

  • Publication number: 20060035728
    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.
