Abstract

A ball safety netting system includes a net comprising a plurality of openings, a plurality of elongated poles having a lower end operably attachable to the ground in spaced-apart relationship, and a plurality of safety devices operably attachable to the plurality of poles and operably attachable to the net. The plurality of poles and the plurality of safety devices are operably sized and configured for use in supporting the net in a generally fixed upright relationship relative to the ground, and when a force exerted on the safety device exceeds a breaking point of the safety device, a portion of the net is detaches from the pole to reduce the likelihood of pole failure.

Claims

1. A method for reducing the likelihood of pole failure when supporting a net, the method comprising:

supporting the net in a generally fixed upright relationship relative to the ground from a plurality of elongated poles having a length of about 12 feet to about 40 feet and spaced-apart about 10 feet to about 25 feet with a plurality of tethers; and

allowing an upper portion of the net to automatically operably disconnect from a tether and fall from a pole toward the ground when the net exerts a force on the tether greater than a force between about 125 pounds to about 175 pounds to reduce the likelihood of pole failure;

wherein the supporting comprises a breakaway pin having a first portion and a second portion disposed in a first configuration with the first portion operably attached to an end of the tether and the second portion operably attached to an upper portion of the net; and

wherein the allowing comprises the breakaway pin being disposed in a second configuration allowing the upper portion of the net to automatically operably disconnect from the tether.

2. The method of claim 1 wherein at least a portion of the breakaway pin comprises sufficient weight to act as a counterweight to allow lowering of the tether after allowing the upper portion of the net to automatically operably disconnect from the tether and fall from the pole toward the ground.

3. The method of claim 2 wherein the at least the portion of the breakaway pin comprises a weight of about 1 pound.

4. The method of claim 2 further comprising:

lowering the end of the tether under the weight of the at least the portion of the breakaway pin;

operably attaching the upper portion of the net to the end of the tether with the breakaway pin; and

raising the upper portion of the net using the tether.

5. The method of claim 1 wherein the allowing comprises the first portion of the breakaway pin separating from the second portion of the breakaway pin.

6. The method of claim 5 wherein the force comprises a force between about 135 pounds to about 165 pounds.

7. The method of claim 5 wherein the force comprises a force of about 150 pounds.

8. The method of claim 5 further comprising absorbing impact between the breakaway pin and the pole with a resilient bumper member disposed around the breakaway pin.

9. The method of claim 5 wherein the allowing further comprises slidably restraining a middle portion of the net to the pole and allowing the middle portions of the net to fall toward the ground.

10. The method of claim 5 wherein the allowing further comprises restraining a lower portion of the net to the pole.

11. The method of claim 5 wherein the net comprises a plurality of openings between about 1 inch and about 4 inches.

12. The method of claim 5 wherein the supporting comprises supporting the plurality of poles in a plurality of sleeves mountable in the around.

13. The method of claim 5 wherein the supporting comprises supporting the net disposed between at least one of adjacent playing fields, and an athletic playing field and spectators.

14. The method of claim 1 wherein the breakaway pin comprises a first portion operably attachable to the tether and a second portion operably attachable to the upper portion of the net, and a shear pin operably connecting the first portion to the second portion.

15. The method of claim 14 wherein the force comprises a force between about 135 pounds to about 165 pounds.

16. The method of claim 14 wherein the force comprises a force of about 150 pounds.

17. The method of claim 5 wherein the first portion of the breakaway pin comprises sufficient weight to act as a counterweight to allow lowering of the tether after failure of the breakaway pin.

18. The method of claim 17 wherein the first portion of the breakaway pin comprises a weight of about 1 pound.

19. The method of claim 17 further comprising:

lowering the end of the tether under the weight of the first portion of the breakaway pin;

reassembling the breakaway pin; and

raising the upper portion of the net using the tether.

20. The method of claim 1 further comprising absorbing impact between the breakaway pin and said pole with a resilient bumper member disposed around the breakaway pin.

21. The method of claim 14 wherein the first portion comprises a generally hollow member having a passageway therethrough defining a longitudinal axis.

22. The method of claim 21 wherein the second portion comprises an elongated member having an upper end portion having a hole therethrough, the upper end portion receivable in the passageway of the generally hollow member, and the shear pin disposed in the hole of the second portion.

23. The method of claim 22 wherein when the breakaway pin is assembled, the second portion and the shear in are rotatable 360 degrees around a longitudinal axis of the generally hollow member.

24. The method of claim 14 wherein the shear pin comprises aluminum having an outside diameter of about ¼

inch.

25. The method of claim 14 wherein the allowing further comprises slidably restraining a middle portion of the net to the pole and allowing the middle portions of the net to fall toward the ground.

26. The method of claim 14 wherein the allowing further comprises restraining a lower portion of the net to the pole.

27. The method of claim 14 wherein when the breakaway pin is assembled, the shear pin is rotatable 360 degrees around a longitudinal axis of the breakaway pin.

28. The method of claim 14 wherein the supporting comprises supporting the net disposed between at least one of adjacent playing fields, and an athletic playing field and spectators.

29. The method of claim 1 wherein the force comprises a force between about 135 pounds to about 165 pounds.

30. The method of claim 1 wherein the force comprises a force of about 150 pounds.

31. The method of claim 1 wherein the allowing further comprises slidably restraining a middle portion of the net to the pole and allowing the middle portions of the net to fall toward the ground.

32. The method of claim 1 wherein the allowing further comprises restraining a lower portion of the net to the pole.

33. The method of claim 1 wherein the net comprises a plurality of openings between about 1 inch and about 4 inches.

34. The method of claim 1 wherein the supporting comprises supporting the plurality of poles in a plurality of sleeves mountable in the ground.

35. The method of claim 1 wherein the supporting comprises supporting the net disposed between at least one of adjacent playing fields, and an athletic playing field and spectators.
