Rail accessory mount
A u-shaped clamp that includes offset bends at distal ends, accepts a threaded fastener through two apertures, where tightening the fastener brings two flanges of the u-shaped clamp together to grip a wire, a cable or a pipe. An offset bend on one end of one flange serves to hold a wire or cable in position until the fastener is tightened.
1. A u-shaped clamp, comprising:
a substantially planar first flange, the first flange having a first aperture; and
a second flange, the second flange having a second aperture, wherein the first aperture and the second aperture are configured to allow a fastener to pass through both apertures, wherein the first flange and the second flange connect to each other with a u-shaped bend, the second flange having a substantially planar first portion that surrounds the second aperture, and an second portion having an offset bend, the offset bend on the second portion being opposite the u-shaped bend with respect to the second aperture, the offset bend configured to receive an inserted wire, cable, or pipe in a solar array, and wherein one or more of the flanges is configured to form an electrical bonding connection with the inserted wire, cable, or pipe when the fastener is tightened.
2. The u-shaped clamp of claim 1 , wherein the offset bend on the second portion is offset toward the first flange.
3. The u-shaped clamp of claim 2 , wherein the offset bend on the second flange is further configured to hold the inserted wire, cable, or pipe substantially tangent to the fastener, when the fastener has been passed through the first and second apertures.
4. The u-shaped clamp of claim 2 , wherein the offset bend on the second flange has a terminal portion bent away from the first flange, the bending of the terminal portion configured to facilitate insertion of the wire between the first flange and the second flange.
5. The u-shaped clamp of claim 2 , wherein the offset bend provides a spring action to retain the inserted wire between the second flange and the first flange before the fastener is tightened.
6. The u-shaped clamp of claim 2 , wherein the first flange and the second flange are brought together when the fastener is tightened, and wherein the substantially planar first flange and the substantially planar first portion of the second flange clamps the inserted wire, cable, or pipe therebetween when the fastener is tightened.
7. The u-shaped clamp of claim 1 , wherein the offset bend on the second portion is offset away from the first flange.
8. The u-shaped clamp of claim 7 , wherein the offset bend on the second flange has a terminal portion bent toward the first flange, the bending of the terminal portion configured to hold the inserted wire, cable, or pipe between the first flange and the second flange before the fastener is tightened.
9. The u-shaped clamp of claim 1 , wherein an outer perimeter of the substantially planar first flange is substantially circular.
10. The u-shaped clamp of claim 1 , wherein a diameter of the second aperture is greater than a diameter of the first aperture.
11. The u-shaped clamp of claim 1 , wherein the clamp is formed from a substantially uniform thickness metal.
12. The u-shaped clamp of claim 1 , wherein the clamp is stainless steel or aluminum.
13. The u-shaped clamp of claim 1 , wherein the electrical bonding connection is formed between the clamp, the inserted wire, cable, or pipe, and the fastener.
14. A method of installing a wire, cable, or pipe into the u-shaped clamp of claim 1 , the method comprising:
inserting the wire, cable, or pipe into a space between the first flange and the second flange; and
threadably tightening the fastener, causing the inserted wire, cable, or pipe to be clamped between the first flange and the second flange.
15. A clamp system for a solar panel array, comprising:
a threaded fastener;
a threaded nut cooperating with the threaded fastener, and
a u-shaped clamp, the u-shaped clamp comprising:
a substantially planar first flange, the first flange having a first aperture; and
a second flange, the second flange having a second aperture, wherein the first aperture and the second aperture are configured to allow the fastener to pass through both apertures, wherein the first flange and the second flange connect to each other with a u-shaped bend, the second flange having a substantially planar first portion that surrounds the second aperture, and an second portion having an offset bend, the offset bend on the second portion being opposite the u-shaped bend with respect to the second aperture, the offset bend configured to receive an inserted wire, cable, or pipe in a solar array, and wherein one or more of the flanges is configured to form an electrical bonding connection with the inserted wire, cable, or pipe when the fastener is tightened within the apertures.
