Patent ID: 8485912

Claim:
A powerless automatic tee up machine comprising: a main body unit including a golf ball receptacle that receives a golf ball and sequentially feeds the golf ball through an outlet, a support for supporting the golf ball receptacle, and a plate extending from the support; an outlet block unit that is disposed on the support so as to rotate upward and open or shut an outlet of the golf ball receptacle; a rotating unit including an arm that has a lower portion rotatably fixed to the support and that rotates by the golf ball received from the golf ball receptacle so as to transport the golf ball to a golf tee, a weight disposed on the inside of a distal end of the arm so that the arm rotates toward the outlet without using power, an elevating member disposed on a central portion of the arm so as to rotate upward the outlet block unit, a seating member for seating the golf ball ejected as the outlet block unit rotates upward, and a hinge disposed at the distal end of the arm so that its end rotates only inward; and a rotation control unit including a balancer that moves up or down in equilibrium depending on whether the rotating unit has transported the golf ball to the golf tee, a connection member that keeps the balancer raised and rotates downward when the golf ball sits on the golf tee, a rotary shaft that is coupled to the connection member and rotates in a direction in which the connection member moves, and a support member that is disposed at a distal end of the rotary shaft, is positioned behind the hinge as it rotates by the golf ball placed on the golf tee in such a way as to prevent the rotating unit from rotating, and returns to its original position when the golf ball falls off the golf tee so that the rotating unit having the golf ball laid thereon rotates toward the golf tee.
