  • Patent number: 10173117
    Abstract: A ball-returning net comprises a vertical wire frame, a vertical net, a floor wire frame, a slope net, two side barrier nets, and a detachable strap. The vertical net is fixed to the edge portion of the vertical wire frame and blocking the opening of the vertical wire frame. The slope net is disposed over the floor wire frame so as to be tilted from an elevated lower portion of the vertical net to a front edge portion of the floor wire frame, so as to be configured that a ball hitting the vertical net falls down on the slope net and rolls down in a direction of the front edge portion of the floor wire frame. The detachable strap holds the slope net and the vertical wire frame tightly, bending a rear portion of the slope net in a V shape.
