发明名称 Golf ball drive length indicating apparatus
摘要 The golf ball receiving apparatus includes a net structure for enclosing a liquid filled container having a flexible front wall facing an open side of the net structure and constituting a ball target. The impact force applied on the front wall displaces liquid within the container in volume amounts proportional to the magnitude of the impact force. The displaced liquid is confined for movement into an accumulator chamber associated with an operator member, movable in response to the volume of displaced liquid, and directed to actuate a transfer member which transmits the magnitude of the impact force to a drive indicating gauge or scale. After striking the target, the driven balls are directed into a receptacle that is manually movable to deliver the balls to a collection area for reuse or for feeding into a practice driving machine.
