A ball-returning tennis net assembly comprises a net structure of an inner net and an outer net on each side of the inner net for gathering balls hit into the net structure in a manner preventing the balls from rebounding onto a playing surface of a tennis court and for causing the balls to drop into an elongate inclined tray positioned along the base of the net so that the collected balls will roll down the tray to one end of the net structure. The tray delivers the ball to an automatic ball return mechanism at the side of the court which has a powered paddle device for batting the balls to a selected location at either end of the court.

A basketball return device comprises a portable unit for positioning on a basketball court in a location generally underneath a basket into which shooting practice is to be conducted. The device includes a base with a ball-return mechanism therein and a vertically extending chute projecting upwardly from the base and terminating in a hoop-like top opening for positioning substantially directly beneath the basket. The ball-return mechanism includes a horizontal ball-collection and dispersion tube mounted in the base for swinging movement about a vertical axis so that the tube may be positioned to direct balls through an open end thereof to a required location on the court. The ball-return mechanism includes a solenoid operated plunger carried at the back of the tube for projecting balls therethrough and the device may include various electrical controls for automatically and semi-automatically operating the ball-return mechanism.

A tennis ball return apparatus associated with a tennis net which has its lower edge disconnected from supporting posts to enable balls striking the net to drop substantially straight downwardly rather than rebounding from the net with the apparatus of this invention causing the tennis balls which strike the net and drop downwardly to enter a channel-shaped area having a horizontal tray or trough in the bottom thereof which has a driven endless cord with knots thereon for returning the balls to a putter-type mechanism to project the balls back towards the base line of a tennis court.
