发明名称 Apparatus for picking up balls
摘要 An apparatus for picking up balls, especially tennis balls, is provided with a ball collection basket which has a ball inlet device in its base. The ball inlet device possesses longitudinal parts extending between two opposing lateral walls of the ball collection basket and arranged at least approximately parallel to each other and at a distance from each other and/or from the lateral walls lying at least approximately parallel thereto, this distance being slightly less than the diameter of a ball to be received. Collection or release frames, which are pivotable about a horizontal axis, are attached to the ball collection basket. The longitudinal parts are resilient and are, for example, helical springs.
