  • Device for collecting balls or other objects capable of rolling
    Patent number: 4596414
    Abstract: The device comprises two shells equipped with casters allowing it to move. The shells can pivot on vertical hinges as a result of the movement of a grip sliding along a handle connected to the hinges. The grip is connected to the shells by arms attached through omnidirectional joints to the grip and to each arm. Movement of the grip in one direction causes the shells to open, and movement in the other direction causes them to close to form a box. The device can be used to collect tennis balls without excessive fatigue.
