Flying ball stopping net for ball games
First Claim
1. A flying ball stopping net device for ball games, including a plurality of legs arranged side by side on the ground and respectively extending in one direction that is substantially horizontal, a frame body extending above said legs and substantially orthogonally to said one direction and along a substantially vertically extending imaginary plane, supports for supporting the lower portions of said frame body at longitudinally intermediate portions of said legs, and a flying ball stopping net closing the space surrounded with the outer edge of said frame body and attached to said frame body,said flying ball stopping net device for ball games being characterized in that each support comprises a first support pipe projecting upward from the longitudinal intermediate portion of the leg, a second support pipe projecting downward from the lower portion of the frame body and removably fitted to said first support pipe for relative turning movement around the axis thereof, and an elastic locking body having one end fitted in one of the first and second support pipes and locked therein and the other end removably fitted in the other one of the first and second support pipes to be pressed against the inner peripheral surface thereof, and in that the inner peripheral surface of the other support pipe and the other end of the said locking body pressed against said inner peripheral surface are relatively slidable around the axis of the other support pipe, the pressing surface of the other end of said locking body pressed against the inner peripheral surface of said other support pipe, as seen in a plan view, is an arcuate surface whose surface is smaller than the inner radius of said other support pipe, and the inner peripheral surface of said other support pipe is formed with a circumferentially extending annular groove, and the other end of the locking body is resiliently biased in removable engagement with said groove.

Abstract
A flying ball stopping net device having a plurality of legs arranged side by side one ht ground. The legs extend in one direction substantially horizontal with a frame extending upward away from the legs. The frame has supports that support lower portions of the frame body at longitudinally intermediate portions of the legs. A net surrounds the outer edge of the frame body to which it is attached. Each support includes a first support pipe projecting upward from the longitudinal intermediate portion of the leg. A second support pipe projects downwardly from the lower portion of the frame body and is removably fitted to the first support pipe for relative turning movement around the axis thereof. An elastic locking body having one end fitted in one of the first and second support pipes and is locked therein. The other end of the elastic body is removably fitted in the other one of the first and second support pipes to be pressed against the inner peripheral surface thereof. The inner peripheral surface of the other support pipe and the other end of the locking body are relatively slidable around the axis of the other support pipe.
