US Patent 8002648 Corkscrew tee ball stand

A tee ball stand with an adjustable length ball support stanchion having an anchor connection fitting on the lower end thereof, and a ground penetrating corkscrew anchor equipped with a stanchion connection fitting on the upper end thereof. The anchor connection fitting of the stanchion may be frictionally coupled to the stanchion connection fitting to hold the stanchion in an upright orientation to receive a ball on the upper end thereof. The ground penetrating corkscrew anchor prevents displacement of the tee ball stand in the event the stanchion is struck by an errant bat swing.
