US Patent 7704165 Golf ball support or tee

The invention relates to a novel golf ball support or tee comprising a lower part which is fixed to the practice surface and an upper part which is disposed above ground. The upper end of the upper part comprises a surface which receives the golf ball. According to the invention, the support comprises an obstacle-forming protrusion which prevents the ball from moving during the positioning thereof. Said protrusion extends upwards from at least one side of the upper part of the device, such that, when the ball is in the rest position on the receiving surface, the protrusion and the ball are not in contact with one another.
