  • Patent number: 5823885
    Abstract: A portable personal sporting net includes a tapered cylindrical or funnel-like tubular, pliable, porous net having an enlarged entrance aperture which is supported by a collapsible pole. In one embodiment, a suspended exit aperture is formed at the opposing end of the netting. A ball capture bag communicates with the exit aperture to catch balls hit into the netting. In an alternative embodiment, the opposing second end of the netting is closed against the ground surface. A pair of flaps are mounted on opposing sides of the entrance aperture and radially extend forward and outward therefrom. The flaps assist in directing stray balls into the funnel-like netting.
