Abstract

A method of coupling two pipes includes fastening two coupling segments into an untightened configuration, the two coupling segments comprising a first segment and a second segment, the first segment comprising a first end and a second end distal to the first end, the second segment comprising a first end and a second end distal to the first end, wherein fastening the two coupling segments comprises: placing a pivot clip between the second end of the first segment and the first end of the second segment, the pivot clip configured to maintain a separation distance between the second end of the first segment and the first end of the second segment; and tightening a first tightening element to draw the second end of the first segment towards the first end of the second segment; and placing ends of the two pipes between the two coupling segments.

First claim

That which is claimed is:

1. A method of coupling two pipes, the method comprising:
fastening two coupling segments of a pipe coupling into an untightened configuration, the two coupling segments comprising a first segment and a second segment, the first segment comprising a first end and a second end distal to the first end, the second segment comprising a first end and a second end distal to the first end, wherein fastening the two coupling segments comprises:
placing a pivot clip between the second end of the first segment and the first end of the second segment, the pivot clip configured to maintain a separation distance between the second end of the first segment and the first end of the second segment; and
tightening a first tightening element to draw the second end of the first segment towards the first end of the second segment; and

placing ends of the two pipes between the two coupling segments;
wherein:
the second segment further comprises a tongue at the first end of the second segment;
placing the pivot clip between the second end of the first segment and the first end of the second segment comprises substantially surrounding an outer surface of the tongue with the pivot clip;
the pivot clip defines an upper surface, a lower surface opposite the upper surface, an interior edge, an outside edge opposite the interior edge, and two lateral edges;
the interior edge defines a notch;
the interior edge substantially surrounds the outer surface of the tongue; and
at least a portion of the tongue is disposed within the notch.

2. The method of claim 1 , further comprising tightening a second tightening element to draw the first end of the first segment towards the second end of the second segment, and wherein tightening the second tightening element configures the pipe coupling in a tightened configuration.

3. The method of claim 2 , wherein fastening the two coupling segments into the untightened configuration occurs before placing ends of the two pipes between the two coupling segments, and wherein tightening the second tightening element occurs after placing the ends of the two pipes between the two coupling segments.

4. The method of claim 3 , wherein tightening the second tightening element comprises deforming the two coupling segments around the two pipes.

5. The method of claim 2 , wherein each of the first tightening element and the second tightening element comprises a nut and a bolt.

6. The method of claim 5 , wherein tightening the first tightening element comprises extending a first threaded tail of the bolt of the first tightening element through a first fastener pad of the first segment and a second fastener pad of the second segment and rotating the nut of the first tightening element on a first distal end of the first threaded tail.

7. The method of claim 6 , wherein the first threaded tail defines an inner portion and an outer portion, and wherein placing the pivot clip between the second end of the first segment and the first end of the second segment comprises substantially surrounding the inner portion with the pivot clip.

8. The method of claim 7 , wherein:
an outside edge of the pivot clip defines a cutout;
the outside edge surrounds the inner portion of the bolt; and
the bolt is substantially disposed within the cutout.

9. The method of claim 8 , wherein the pivot clip further defines a pair of prongs, wherein the pair of prongs are disposed on either side of the cutout.

10. The method of claim 6 , wherein:
the first segment further comprises a third fastener pad opposite the first fastener pad;
the second segment further comprises a fourth fastener pad opposite the second fastener pad; and
tightening the second tightening element comprises extending a second threaded tail of the bolt of the second tightening element through the third fastener pad of the first segment and the fourth fastener pad of the second segment and rotating the nut on a second distal end of the second threaded tail.

11. The method of claim 10 , wherein, in the tightened configuration of the pipe coupling:
the separation distance is a minimum separation distance;
the third fastener pad of the first segment and the fourth fastener pad of the second segment define a tightening gap therebetween; and
the minimum separation distance and the tightening gap are substantially equal.

12. The method of claim 1 , wherein the pivot clip further comprises a body and a pair of arms, wherein the pair of arms are disposed on either side of the notch.

13. The method of claim 12 , wherein each of the arms is angled relative to the body, the arms being non-coplanar with the body.

14. The method of claim 13 , wherein the pair of arms are substantially parallel with one another.

15. The method of claim 1 , wherein the pivot clip comprises sheet metal.

16. The method of claim 1 , wherein the pivot clip defines a substantially uniform thickness.

17. A method of coupling two pipes, the method comprising:
fastening two coupling segments of a pipe coupling into an untightened configuration, the two coupling segments comprising a first segment and a second segment, the first segment comprising a first end and a second end distal to the first end, the second segment comprising a first end and a second end distal to the first end, wherein fastening the two coupling segments comprises:
placing a pivot clip between the second end of the first segment and the first end of the second segment, the pivot clip configured to maintain a separation distance between the second end of the first segment and the first end of the second segment; and
tightening a first tightening element to draw the second end of the first segment towards the first end of the second segment; and

placing ends of the two pipes between the two coupling segments;
wherein:
the second segment further comprises a tongue at the first end of the second segment;
the pivot clip defines an unenclosed notch; and
at least a portion of the tongue is disposed within the unenclosed notch.

18. The method of claim 17 , wherein the unenclosed notch is substantially U-shaped.

19. The method of claim 18 , wherein the pivot clip defines an interior edge, the interior edge defines the notch, and the interior edge further defines:
a recessed portion;
first arm portion;
a second arm portion opposite the first arm portion;
a first angled connecting portion extending between the recessed portion and the first arm portion; and
a second angled connecting portion extending between the recessed portion and the second arm portion.

20. The method of claim 19 , wherein the pivot clip further defines an outside edge opposite the interior edge and a pair of opposing lateral edges extending substantially between the interior edge and the outside edge.
