Abstract:
A batting practice device comprising:a stabilizing assembly for resting on a ground surface to provide ballast; a post assembly mounted on said stabilizing assembly for orienting in a substantially vertical orientation, said stabilizing assembly extending away from said post assembly in a longitudinal direction; a rotating arm assembly having a rotating arm with a first end and a second end, said first end of said rotating arm being rotatably mounted on said vertical post assembly; and a biasing assembly for biasing said rotating arm into a centered position in which said rotating arm assembly extends from said post assembly in an opposite longitudinal direction from said stabilizing assembly, said biasing assembly including a pair of tension members extending from said rotating arm assembly to said stabilizing assembly, first ends of said tension members being mounted on said stabilizing assembly at laterally spaced locations and second ends of said tension members being mounted on said rotating arm assembly such that rotation of said rotating arm assembly from said centered position increases tension in said tension members and said increase in tension tends to rotate said rotating arm assembly toward said centered position; a pull cord having a first end mounted on said rotating arm between said first and second ends of said rotating arm such that pulling on said second end of said pull cord moves said rotating arm out of said centered position and increases tension in said tension members so that release of said pull cord causes said rotating arm toward said centered position to simulate movement of a pitched ball by a ball mounted on said rotating arm.
