Abstract

A coupler for connecting a first element to a second element includes a first connector piece securable to the first element; a second connector piece for attaching to the first connector piece; and a flexible breakaway device mounted on the second element for releasably securing the second connector piece to the second element. A method of connecting and disconnecting a first element and a second element includes the steps of providing a first connector piece on the first element; attaching a breakaway device to the second element; attaching a second connector piece to the breakaway device that is attached to the second element; securing the first connector to the second connector; releasing the second connector piece from the second element by deflecting a portion of the breakaway device when a separation force is applied between the first and second elements.

Claims

1. A coupler for connecting a first element to a second element, the coupler comprising:

a first connector piece securable to the first element;

a second connector piece for attaching to the first connector piece; and

a flexible breakaway device mounted on the second element for releasably securing the second connector piece to the second element.

2. The coupler of claim 1, wherein the first and second connector pieces are threadably connectable to each other.

3. The coupler of claim 2, wherein the first and second connector pieces are rigid.

4. The coupler of claim 1, wherein the breakaway device includes a ring portion and a flexible portion extending radially from the ring portion.

5. The coupler of claim 4, wherein the second connector piece includes a flange for engaging the flexible portion of the breakaway device.

6. The coupler of claim 1, wherein the breakaway device is permanently mounted to the second element.

7. The coupler of claim 1, wherein the breakaway device is permanently mounted to the second connector.

8. A coupler for connecting a first element to a second element, the coupler comprising:

a first connector piece securable to the first element;

a second connector piece for attaching to the first connector piece; and

a breakaway device slidably mounted on the second element, wherein the second connector is releasably secured to the breakaway device.

9. The coupler of claim 8, wherein the first and second connector pieces are threadably connectable to each other.

10. The coupler of claim 8, wherein the breakaway device is flexible.

11. The coupler of claim 10, wherein the first and second connector pieces are rigid.

12. The coupler of claim 8, wherein the breakaway device includes a ring portion and a flexible portion extending radially from the ring portion.

13. The coupler of claim 12, wherein the second connector piece includes a flange for engaging the flexible portion of the breakaway device.

14. A coupler for connecting a first element to a second element, the coupler comprising:

a first connector piece securable to the first element;

a second connector piece securable to the first connector piece;

a breakaway device slidably secured to the second element, the breakaway device including a portion that engages the second connector and which disengages the second connector when a predetermined separation force is applied between the breakaway device and the second connector.

15. The coupler of claim 14, wherein the first and second connector pieces are threadably connectable to each other.

16. The coupler of claim 14, wherein the breakaway device includes a ring portion and a flexible portion extending radially from the ring portion.

17. A method of connecting and disconnecting a first element and a second element, comprising the steps of:

providing a first connector piece on the first element;

attaching a breakaway device to the second element;

attaching a second connector piece to the breakaway device that is attached to the second element;

securing the first connector to the second connector;

releasing the second connector piece from the second element by deflecting a portion of the breakaway device when a separation force is applied between the first and second elements.
