  • Patent number: 5571055
    Abstract: Presented is a golf tee device having ground anchoring prongs to stabilize the tee upon impact with a club head and keep the tee from "popping" out of the ground and traveling haphazardly. Also, the tee incorporates a circular non-adjustable base feature that limits the depth to which the tee can be inserted into the ground, thereby adjusting the elevation of the golf tee, and thus providing a platform for the golf ball that is the proper elevation to meet the needs of a particular golfer. Further, the base feature also aligns the tee in a perpendicular position relative to the ground. Incorporation of spine supporting radii above and below the base feature serve to significantly increase the strength and resiliency of the device.
