Standing seam roof clamp
View Patent ↗A clamp for attaching solar panel grids to standing seam roof structures. The clamp includes opposing clamp halves having inter-engageable projections and recesses. One or more fasteners engage the halves to draw them together. A first set of recesses on one clamp half receives a first set of projections on the other half. A second set of recesses on the other clamp half receives a second set of projections. When loose, the first set of projections engage the first set of recesses like a detent, while the second set of projections are spaced apart from the second set of recesses to enable the clamp to be slid down onto the vertical seam of a standing seam roof. Tightening the fasteners causes the second set of projections to deform the seam into the second set of recesses, fixing the clamp to the seam.
1. A solar panel clamp, comprising:
first and second opposing clamp portions;
the first clamp portion comprising a first end and a second end, the first end including a first projection and the second end including a first recess;
the second clamp portion comprising a first end and a second end, the first end including a second recess and the second end including a second projection;
a fastener engageable with the first and second clamp portions;
the clamp having a loosened configuration in which the first projection is received within the second recess and the second projection is spaced apart from the first recess by a first distance, and the clamp further has a tightened configuration in which the first projection is received within the second recess and the second projection is receivable within the first recess;
one of the first and second clamp portions further includes a receiving section disposed substantially perpendicular to a longitudinal axis of the solar panel clamp, the receiving section having at least one fastener hole to facilitate connecting said clamp to a solar panel grid.
2. The solar panel clamp of claim 1 , comprising a spring disposed between the first and second clamp portions to bias the clamp portions apart.
3. The solar panel clamp of claim 2 , the spring comprising a coil spring disposed about the fastener.
4. The solar panel clamp of claim 1 , the second ends of the first and second clamp portions having distal portions that are flared apart.
5. The solar panel clamp of claim 1 , wherein the second projection is rounded.
6. A clamp, comprising:
first and second opposing clamp portions engageable with each other at first and second ends; and
a fastener engaged with the first and second clamp portions;
the clamp having a loosened configuration in which the first and second clamp portions are connected at the first end and are separated by a first distance at the second end;
the clamp having a tightened configuration in which, at the second end, the first and second clamp portions are positioned closer to each other than the first distance;
the first and second clamp portions having corresponding projections and recesses disposed at the second end for deforming a captured portion of a roof seam into the recess disposed at the second end as the clamp is moved from the loosened configuration to the tightened configuration;
one of the first and second clamp portions having a receiving section disposed substantially perpendicular to a longitudinal axis of the clamp, the receiving section having at least one fastener hole to facilitate connecting said clamp to a solar panel grid.
7. The clamp of claim 6 , comprising a spring disposed between the first and second clamp portions to bias the clamp portions apart.
8. The clamp of claim 6 , the second ends of the first and second clamp portions having distal portions that are flared apart.
9. The clamp of claim 6 , wherein the projections are rounded.
10. The clamp of claim 6 , the receiving section associated with the first end of said first clamp portion.
11. A solar panel clamp, comprising:
first and second opposing clamp portions;
the first clamp portion comprising a first end and a second end, the first end including a first projection and the second end including a first recess;
the second clamp portion comprising a first end and a second end, the first end including a second recess and the second end including a second projection;
a coil spring disposed between the first and second clamp portions to bias the clamp portions apart; and
a fastener engageable with the first and second clamp portions, the coil spring disposed about the fastener;
wherein the clamp has a loosened configuration in which the first projection is received within the second recess and the second projection is spaced apart from the first recess by a first distance, and the clamp further has a tightened configuration in which the first projection is received within the second recess and the second projection is positioned closer to the first recess than said first distance.
12. The solar panel clamp of claim 11 , the second ends of the first and second clamp portions having distal portions that are flared apart.
13. The solar panel clamp of claim 11 , wherein the second projection being rounded.
14. The solar panel clamp of claim 11 , one of the first and second clamp portions having a receiving section disposed substantially perpendicular to a longitudinal axis of the solar panel clamp, the receiving section having at least one fastener hole to facilitate connecting said clamp to a solar panel grid.
