Abstract: A sport carrying bag has a rotatable disc which is configured with a plurality of circumferentially spaced ball-receiving regions including one through-hole region, a mounting plate located below the disc, a chute downwardly extending to a loading section of launching apparatus, a fixed bi-directional ball feeding motor for rotatably driving the disc, and a controller in data communication with the ball feeding motor. Upon rotation of the disc in a first direction, a ball received in the through-hole region ceases to be contacted by the mounting plate and gravitates through the chute to the loading section of the launching apparatus. In response to a detected jammed condition, the controller commands the ball feeding motor to reverse its operating direction such that the disc will rotate in a second direction to cause one or more jammed balls to become dislodged.

Abstract: A carrying bag comprises a ball hopper compartment, an automatic launching apparatus configured to launch balls to a distance from the bag, a ball sorting apparatus for loading balls to the launching apparatus from a bottom side opening of the ball hopper compartment, which in one embodiment is configured with an anti-jamming function, and a four contact point base with the ground to provide stability both when the bag is stationary as well as while balls are being launched.

Abstract: A ball retrieval device; comprises: a) a telescopic tubing assembly suitable to house a plurality of balls; b) a retrieval mechanism suitable to allow the passage of a ball into said tubing assembly and to prevent its discharge therefrom; c) a positioning element suitable to cooperate with slotted connecting elements and to prevent the undesired rotation of parts of said telescopic tubing assembly relatively to one another; and d) capping element provided with stopping elements, suitable to release balls from the device when said stopping elements are in an open position.

Abstract: A carrying bag for sports equipment comprises compartments suitable to accommodate sports equipment; and an automatic launching apparatus configured to launch sports balls to a distance from the bag.
