发明名称 Removable pitching rubber
摘要 A removable pitching rubber comprising a pitching pad and a rigid metal plate removably connected to the pad, and at least two metal posts extending downwardly from the plate for insertion into prearranged ground anchors embedded in the ground so as to provide a stationary mount for the pitching rubber. The removable connection between the plate and the pad permits the pad to be separated from the plate and replaced when worn. The plate is formed with a downwardly turned lip at each longitudinal edge, the lips penetrating the ground when the pitching rubber is installed to stabilize the rubber.
