Abstract

A portable return net device for receiving, arresting and returning a ball to a central collection point for pitched, thrown or batted balls in a ball practice system. The return net apparatus comprises; a net supporting frame, a net for receiving a projected ball, an inclined collection tray operatively associated with the net, and an exit chute, wherein the net is hung untensioned on the supporting frame, on the diagonal, and wherein flaps extending transversely across the base of the hanging net are pivotally connected thereto. The net absorbs the impact of a ball in conjunction with the flaps which trap a ball impacting a tensile zone of the net. The tensile zone comprises that portion of the hanging net below which there is insufficient net weight to arrest a ball in a triangular portion of the net below the point of impact. The arrested ball is conveyed by the collection tray to the exit chute for reuse.

Claims

1. A ball return net apparatus, adapted to be selectively operated in conjunction with a ball tossing system, the apparatus comprising:

a net supporting frame;

a net on the frame to receive and arrest a projected ball;

an inclined collection to operatively associated with the net;

an exit chute,

wherein the net is hung untensioned on the supporting frame, on the diagonal, and wherein flaps extend transversely across the base of the hanging net are pivotally connected thereto.

2. The apparatus of claim 1 wherein the net includes an inclined extension overlying a portion of the collection tray.

3. The apparatus of claim 2 wherein the flaps are pivotally connected adjacent the base of the net for pivotal motion between a first position supported parallel to the tray surface, and a second generally vertical position extending upwardly from the tray, generally parallel to the hanging net surface.

4. The apparatus of claim 3 wherein a ball impacting on a tensile zone adjacent the base of the net is trapped between the net and a flap in the vertical position.

5. The apparatus of claim 3 wherein the flaps have a dimension normal to the pivotal axis equal to the height of the rebound zone.

6. The apparatus of claim 2 wherein the net is a mesh having a weight in the range of a 0.5 to 4 oz. per square foot.

7. The apparatus claim 2 wherein the collection tray has a weight in the order of 2½

oz. per square foot.

8. The apparatus claim 2 wherein the collection tray has a weight in the range of 1 to 5 oz. per square foot.

9. The apparatus claim 2 wherein the inertia flaps have a weight in the order of 5 oz. per square foot.

10. The apparatus claim 2 wherein the inertia flaps have a weight in the range of 2 to 10 oz. per square foot.

11. The apparatus of claim 2 wherein the exit chute connects to a vertical ball tossing device.

12. The apparatus of claim 1 operationally combined with a vertical ball tossing device.

13. A return net device for receiving and arresting a ball and returning it to a collection point comprising:

a frame having a net frame portion and a collection frame portion, the collection frame portion being operatively associated with the net frame portion;

a net supported on the diagonal within the net frame; and

an inclined collection tray supported by the collection frame

wherein the net includes a vertical net portion hanging from the net frame, sufficiently loosely to avoid rebound of the ball and an inclined portion overlying the collection tray;

and wherein the collection tray is sufficiently tensioned to allow a ball to roll from the net to the collection point;

the device further including trap means adapted to inhibit any rebound of a ball striking a tensile zone of the net.

14. The device of claim 13 wherein the tensile zone of the net comprises that portion of the hanging net below which there is insufficient net weight in the triangular portion of the net below the point of impact to arrest a ball striking the net.

15. The device of claim 14 wherein the trap means comprises one or more flaps pivotally connected at the base of the hanging net portion.

16. The return net device of claim 15 wherein a ball striking the tensile zone causes the flaps to rotate upwardly, trapping the ball against the hanging net portion.

17. The device of claim 16 wherein the flaps have a vertical dimension sufficient to trap a ball striking the tensile zone.

18. The device of claim 13 wherein the net is a mesh having a weight in the range of 0.5 to 4 oz. per square foot.

19. The device of claim 14 wherein the tray has a weight in the range of 1 to 5 oz. per square foot.

20. The device of claim 14 wherein the flaps have a weight in the range of 1 to 10 oz. per square foot.
