| description | The ball cart for tennis balls comprises a foldable structure with wheels to roll on a ground, a ball basket (3) supported on the foldable structure, and a basket position adjusting mechanism. The ball basket (3) comprises a fixed frame (4), a movable bottom (5) vertically movable with respect to the fixed frame (4), side walls (6) attached to the fixed frame, and elastic elements (7) having one end connected to the fixed frame (4) and another end connected to the movable bottom (5). The elastic elements (7) are deformable as a result of a weight of tennis balls (B) supported on the movable bottom (5) and have an elastic modulus selected to allow the movable bottom (5) to gradually ascend or descend according to the amount of tennis balls (B) contained in the ball basket (3) so as to keep an upper level of the tennis balls (B) constant. |
