Abstract
A tennis ball recovery system utilizes an elastic screen (15) suspended from a back stop at an angle and is joined to a trough that lies on the ground by means that allow the screen (15) to pivot as the trough is moved to a storage position against the back court fence (12). In the operative position the screen is at an angle with respect to the vertical. The trough has a frontal wall (18) that rises at a small angle to the ground and this wall terminates in a lip (22) that lies over the bottom wall (17) of the trough. A feed screw (31,31') fits in the bottom of the trough to feed balls retrieved to a central point where they are discharged into a bucket (42).
