Abstract

In various representative aspects, a clamp assembly that secures a solar panel module to a rail support structure that utilizes a generally L-shaped clamp in combination with a t-bolt such that the t-bolt fits through an aperture in the L-shaped clamp. This enables the foot of the t-bolt to be inserted into a guide on the top of the rail support structure so that the clamp can subsequently secure the solar panel module to the rail support structure by using a nut to rotate and tighten the t-bolt within the guide and the top of the clamp is then tightened with continuous rotation of the binding bolt, which also enables raised portions on the foot of the t-bolt and top of the clamp to penetrate surface layers of the rail support and the solar panel module respectively to create an electrical bonding path between the solar panel module and the rail support structure.

First claim

What is claimed is:

1 . A clamp assembly for securing a solar panel module to a rail support and providing an electrical bonding path between them comprising:
a. a middle portion; b. a top lip coupled to a first end of the middle portion wherein the top lip further comprises a raised portion; c. a lower portion coupled to a second end of the middle portion wherein the lower portion further comprises an aperture; d. a t-bolt further comprising:
i. an elongated bolt; and
ii. an enlarged end wherein the enlarged end is coupled to a first end of the elongated bolt; and
e. a nut capable of coupling to a second end of the elongated bolt.

2 . The clamp assembly of claim 1 wherein the top lip, middle portion, and lower portion comprise a generally L-shaped structure.

3 . The clamp assembly of claim 1 further comprising a flange extending from the lower portion and has a width that is less than the width of the lower portion.

4 . The clamp assembly of claim 1 wherein the elongated bolt of the t-bolt is threaded.

5 . The clamp assembly of claim 1 wherein the enlarged end of the t-bolt further comprises at least one raised portion.

6 . The clamp assembly of claim 1 wherein the nut further comprises a serrated side.

7 . The clamp assembly of claim 1 wherein the nut further comprises a serrated flange.

8 . The clamp assembly of claim 1 wherein the raised portion of the top lip extends outward from the top lip.

9 . The clamp assembly of claim 1 wherein the enlarged end is perpendicular to the first end of the elongated bolt.

10 . The clamp of claim 1 wherein the clamp assembly is made from an electrically conducting material.

11 . A method of securing a solar panel module to a rail support comprising the steps of:
a. placing a solar panel module on a rail support further comprising a guide along an end of the rail support; b. inserting an enlarged end of a t-bolt into the guide wherein the t-bolt further comprises an elongated portion coupled to the enlarged end and the enlarged end further comprises a raised portion; c. inserting the elongated portion of the t-bolt through an aperture of a lower portion of a clamp wherein the clamp further comprises:
i. a top lip coupled to a first end of the middle portion wherein the top lip further comprises a raised portion; and
ii. a lower portion coupled to a second end of the middle portion;
d. coupling the top lip to a top portion of the solar panel module; e. turning a nut further comprising a serration on a bottom side of the nut clockwise around the elongated portion until the turning of the nut:
i. creates a rotational force applied to the enlarged end causing the raised portion of the enlarged end to penetrate a surface layer of the inner portion of the guide;
ii. creates a downward force applied to the top lip that causes the raised portion on the top lip to penetrate an outer surface layer of the solar panel module; and
iii. causes the serration to penetrate the surface of the lower portion thereby creating an electrical bonding path between the solar panel module and the rail support through the clamp.

12 . The method of claim 11 wherein the top lip, middle portion, and lower portion comprise a generally L-shaped structure.

13 . The method of claim 11 wherein the lower portion further comprises a flange extending from the lower portion and has a width that is less than the width of the lower portion.

14 . The method of claim 11 wherein the elongated bolt of the t-bolt is threaded.

15 . The method of claim 11 wherein the clamp assembly is made from an electrically conducting material.

16 . The method of claim 11 wherein the nut further comprises a serrated flange and further comprises the step of turning the nut until the serrations penetrate the lower portion of the clamp.
