发明名称 Golf tee insertion device
摘要 A device is provided for facilitating the insertion of a golf tee into the ground under controlled conditions of height and angulation independent of ground surface conditions. The device permits controlled golf tee insertion without bending or stooping through the use of a tee holding head wherein the tee is held in place by spaced-apart arm or spring elements extending downward from the outer diameter of a terminal end of a rod housed in a height adjustment sleeve, the sleeve or chamber is provided with spaced apart cutouts which receive the spring arm elements and allow them to be forced apart when a tee head is forced therebetween, the rod having a bearing surface which is substantially contoured to fit the concave upper surface of a standard golf tee head. The height adjustment sleeve, spaced-apart arm elements, vertical tee alignment and contoured bearing surface permit the tee to be inserted into the ground to a predetermined indicated tee height without disturbing the initial positioning and alignment of the tee due to the action of kinetic energy resulting from insertion thrust. The ground friction overcomes the holding friction exerted on the tee by the insertion device once the tee has been inserted into the ground and the insertion device is lifted up and away from the ground.
