ABSTRACT:
A frame assembly rotatably supported on a pair of laterally spaced wheels that have resilient rims that will not damage the surface of a tennis court as they roll thereon, said frame assembly including an elongate tennis ball receiving basket mounted on the forward portion thereof, with the bottom of the basket at a height above the tennis court surface greater than the diameters of tennis balls resting in random positions on the surface, and the frame including an upwardly and rearwardly extending handle. A shaft extends transversely between aligned opening in laterally spaced legs that form a part of the frame assembly. A tennis ball retrieving assembly that includes laterally spaced pairs of resilient disks is rotatably supported on the shaft, with the lateral spacing between each pair of disks being less than the diameter of a tennis ball, and each pair of disks having beads on the periphery that removably maintain a tennis ball that has entered the annulus space between a pair of disks therein. The retrieving assembly has first clutch means on opposite ends thereof that at all times pressure contact spring loaded clutch means on the wheels, and as a result the wheels and disks rotate concurrently when the invention is moved forwardly. The disks are of lesser diameters than the wheels and do not contact the tennis court surface. A number of spaced extractors displace tennis balls from the annulus spaces and direct the balls into the basket as the invention is moved forwardly over the surface of a tennis court. Means are provided to prevent the wheels and disks rotating when the invention is moved rearwardly.
