US Patent 7641573 Articulating batting tee

A fully articulated batting tee including a first support post with a telescoping stem for height-adjustable support of a baseball. The first support post extends downward from the ball to the ground to provide a first point of ground-support. A lateral support assembly comprises a plurality of lateral struts joined at one end to the first support post and extending laterally therefrom to a second support post. A pivoting coupling is mounted on the second support post, and the coupling includes a plurality of collars for insertion of corresponding struts (each of the collars slidably supports a corresponding one of the lateral struts therein). The second support post extends downward to a practice plate and is anchored thereto, thereby providing a second point of ground-support. The combination of height-adjustment, lateral adjustment and pivoting provide a fully articulating batting tee that can position the ball anywhere over or around the practice plate.
