An automatic table tennis training apparatus includes: a rectangular table tennis table; a pitching machine; a collecting stand; a fence part; a blowing part for blowing the table tennis balls dropped to the ground to move the table tennis balls towards one side end of the lower guide located under the table tennis table; and a transfer part for sucking the table tennis balls moving to one side end of the lower guide to transfer the table tennis balls to the collecting stand.

An agitator for use in agitating lightweight polymeric balls in conjunction with a ball washing device is disclosed and includes a base portion, a standing portion attached to the base portion, with the station portion oriented in a vertical direction and generally perpendicular to a horizontal plane formed by the base portion; a motor having a rotatable shaft, a linkage connected to the rotatable shaft, and a bumper connected to the linkage at a location different from the rotatable shaft; and a tubular member connected to the standing portion, the tubular member having an internal diameter that is generally free of obstructions, to facilitate passage of balls through said tubular member when the balls are subjected to a negative pressure differential within the tubular member for transport to a ball washer device.

A recreational/sport apparatus comprises a playing field, on which a target is arranged protruding from a surface of the playing field, and a ball adapted to be shot toward the target. Conveniently, the apparatus comprises means apt to perform the reconstruction of the trajectory of the ball, those means comprising at least one first camera and at least one second camera apt to simultaneously acquire a plurality of first images and second images, respectively, of the ball, and a central unit which receives the first and second images by means of data reception/transmission means and which processes those first and second images in predetermined consecutive time-intervals, the central unit calculating the two-dimensional position of the ball in each of those first and second images, so as to determine, at each time-interval, the three-dimensional position of the ball by comparing those two-dimensional positions, wherein the target is divided into a plurality of target areas and the central unit is apt to recognize a coordinate at which one of the target areas is intersected by the trajectory of the ball.

A ball pit apparatus for use with a plurality of balls. The ball pit apparatus includes: a base portion configured to provide a ball pit for holding a plurality of balls, wherein the base portion includes one or more inflatable side walls configured to, when inflated, extend around a periphery of the base portion; a roof portion configured to provide a ball chamber for holding a plurality of balls above the base portion; one or more inflatable supports configured to, when inflated, hold the roof portion above the base portion; a suction inlet configured to be in fluid communication with the ball chamber so that, when suction is provided at the suction inlet, suction is also provided to the ball chamber; a ball inlet configured to be in fluid communication with the ball chamber so that, when suction is provided to the ball chamber, a ball received at the ball inlet is drawn into the ball chamber. The roof portion includes an opening configured to face the base portion when the one or more inflatable supports are inflated. The roof portion includes at least one blocking element configured to block the opening so as to prevent balls from falling through the opening when suction is provided to the ball chamber and to not block the opening so as to allow balls to fall through the opening when suction is not provided to the ball chamber.
