ABSTRACT:
An eye-hand coordinator assembly (10) includes support members (12) having a longitudinal axis and a ball supporting arm (14) having a ball (16) disposed at a distal end (18) thereof. A cam member (20, 30) operatively supports the ball supporting arm (14) on the support member (12) and allows the arm (14) and the ball (16) to be displaceable from an initial rest position angularly about the longitudinal axis in response to an impact of the ball (16) while axially shifting along the longitudinal axis. The assembly (10) is characterized by the utilization of a spring (22) to dissipate the energy imparted to the arm (14) upon impact of the ball (16) after a predetermined amount of free movement of the arm (14) from the initial rest position. The spring (22) has a length shorter than the axial distance between the cam member (30) and a stop (24) when the assembly is in the initial rest position. The spring (22 ) is engageable with the stop (24) for compression thereof after the predetermined amount of free movement of the arm (14) whereupon the compressed spring (22) reacts with the stop (24) to return the ball support arm (14) and the ball (16) to the initial rest position. A roller (38, 54) is engageable with a symmetrical cam surface (32) allowing axial displacement of the cam member (30) and arm (14) during use by both left-handed and right-handed batters.
