发明名称 Tennis ball conditioner
摘要 An apparatus for the conditioning, storage and transportation of tennis balls. The tennis ball conditioning, storage, and transportation apparatus is used to condition tennis balls, primarily by heating to a desired operating temperature. Conditioning modifies the internal pressure of the balls and warms the composition of the balls to the desired playing temperature. The tennis ball conditioning, storage, and transportation apparatus includes a housing which may have handles and which has an interior which contains heating and/or cooling elements and which functions as a conditioning and storage chamber. The chamber is divided by a screen upon which the balls rest. A thermostatically controlled heater, cooler and fan achieve the desired temperature then stabilizes the balls at the desired temperature.
