Abstract

A multi-piece clamp for installation on a standing seam is disclosed. One component of the clamp is a clamp body with a clamp body slot formed therein. This slot may be mounted on a standing seam without having to slide the clamp body onto an end of the seam. Another component of the clamp is an insert(s) that may be disposed within the clamp body slot between a clamp body slot wall and the standing seam. One or more seam fasteners may be directed through the clamp body and a clamp body slot wall to secure each of the inserts within the clamp body slot by a compression of the same, and further to secure the clamp to the standing seam.

when said clamp is installed on a standing seam, said first seam fastener and said first insert are disposed on opposite sides of the standing seam, wherein said first seam fastener extends through said first slot sidewall, engages an aligned portion of the standing seam, and forces the aligned portion of the standing seam into engagement with said first insert, which in turn forces said first insert into engagement with said second slot sidewall.

8. A clamp, as claimed in claim 1, wherein:

when said clamp is installed on a standing seam, said first seam fastener and said first insert are disposed on a same side of the standing seam, wherein said first seam fastener extends through said first slot sidewall, engages an aligned portion of said first insert, and forces said first insert into engagement with an aligned portion of the standing seam, which in turn forces the aligned portion of the standing seam into engagement with said second slot sidewall.

9. A clamp, as claimed in claim 1, further comprising:

a second insert that is at least partially disposed within said clamp body slot, wherein when said clamp is installed on a standing seam, said first and second inserts are disposed on opposite sides of the standing seam, wherein said first seam fastener extends through said first slot sidewall, engages an aligned portion of said first insert, and forces said first insert into engagement with an aligned portion of the standing seam in a direction of an aligned portion of said second insert, which in turn forces said second insert into engagement with said second slot sidewall.

a magnitude of said first width is at least generally about twice a magnitude of said second width.

15. A clamp, as claimed in claim 1, wherein:

said clamp body slot further comprises a slot base that extends between said first and second open ends and further that extends between said first and second slot sidewalls, wherein said first insert comprises first and second surfaces, wherein said first surface projects at least generally toward said first seam fastener, wherein said second surface projects at least generally toward said slot base, and wherein a portion of said clamp body slot that include said slot base, along with said second surface of said first insert, collectively define at least a portion of a cavity which at least generally approximates a profile of a head of a standing seam on which said clamp may be installed.

16. A clamp, as claimed in claim 1, wherein:

said first insert interfaces with said second slot sidewall, wherein a surface of said first insert that interfaces with said second slot sidewall is discontinuous.

17. A clamp, as claimed in claim 1, wherein:

said first insert interfaces with said second slot sidewall, wherein said second slot sidewall comprises a groove that extends at least generally an entire length of said clamp body slot, wherein said first insert comprises a convex rib that extends along at least generally an entire length of said first insert and that is disposed within said groove.

18. A clamp, as claimed in claim 1, wherein:
