发明名称 Portable apparatus for practicing batting
摘要 A portable apparatus for practicing batting that includes a frame, a net, and a ball. Each lower terminal end of the frame has a ball-engaging eye bolt. A pair of net-engaging uprights of the frame have a pair of tubes that are formed as one-piece therewith for ease of manufacture by eliminating a need for welding. Button fasteners replaceably maintain the members of the frame together for ease of fabrication and collapsing by eliminating a need for nuts and bolts. A second upper member of the frame has a plurality of ball-engaging blind bores. A lowermost terminal edge of the net drapes so as to prevent any balls from rolling thereunder while providing a dampening effect for the ball when hit thereagainst and is free as a result of the frame being void of a lower cross member for eliminating rebound of a ball that hits low on the net. The ball includes a swivel pulley and a pair of ball-engaging cords, each of which extends from an associated ball-engaging eye bolt to slightly below the ball where they are knotted and then extend together upwardly through a throughbore in the ball, with a snug friction fit, where one ball-engaging cord is then knotted to another ball-engaging cord slightly above the ball and then the another ball-engaging cord extends along the swivel pulley and terminates in a ball-engaging hook that selectively engages one ball-engaging blind bore for adjusting height of the ball from the ground.
