发明名称 Batting tee
摘要 A batting tee includes a base plate having an upper surface and a lower surface including a slot extending in a plurality of discrete directions over said surfaces. A perimeter joining the upper and lower surfaces encompasses an area having a configuration of the sum of a conventional home plate and a forward extension thereto having outwardly flaring side edges. A fastener is situated in and is adjustably movable with respect to the slot. An upright ball support has a lower end coupled to the fastener and an upper end adapted to support a ball. The slot is in the form of inverted T-shaped groove in the upper surface of the base plate and include mutually confronting edges. A portion of the upper surface contiguous to the confronting edges are distinguished from the remainder of the upper surface of the base plate by a difference in surface color outlining the slot.
