Abstract

In various representative aspects, a clamp assembly that secures a solar panel module to a rail support structure that utilizes a generally c-shaped clamp in combination with a t-bolt and a binding bolt such that the t-bolt and binding bolt fit through a pair of apertures in the c-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 rotating the binding bolt, which in turn locks 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 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 rear end; b. a top jaw further comprising:
i. a bottom side;
ii. an aperture; and
iii. a raised portion;
c. a bottom jaw coupled to the top jaw at the rear end wherein the top jaw and bottom jaw form an opening such that:
i. the length of the top jaw is greater than the length of the bottom jaw; and
ii. wherein the bottom jaw further comprises an aperture that is axially aligned with the aperture of the top jaw;
d. a t-bolt further comprising:
i. an elongated bolt; and
ii. an enlarged end wherein the enlarged end is coupled to an end of the elongated bolt;
e. a binding bolt further comprising:
i. an elongated tube;
ii. a nut coupled to an end of the elongated tube such that the elongated tube.

2 . The clamp assembly of claim 1 wherein the rear end, top jaw, and bottom jaw form a generally c-shaped structure.

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

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

5 . The clamp assembly of claim 1 wherein the inside of the elongated tube of the binding bolt is threaded.

6 . The clamp assembly of claim 1 wherein the nut is serrated on one side of the nut.

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 jaw extends outward from the top jaw.

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

10 . The clamp assembly of claim 1 wherein the enlarged end of the t-bolt further comprises a ball detent that is protrudes downward from the bottom of the enlarged end.

11 . The clamp assembly of claim 1 further comprising a patch that frictionally engages the elongated nut and the elongated tube when the elongated tube is rotated around the elongated nut.

12 . The clamp assembly of claim 11 wherein the patch is fixed to the enlongated bolt.

13 . The clamp assembly of claim 11 wherein the patch is made of nylon.

14 . The clamp assembly of claim 1 wherein the raised portion of the top jaw and the raised portion of the foot are capable of penetrating a surface layer of the solar panel module and rail support respectively.

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

16 . 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 on 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 bottom jaw of a clamp and an aperture of a top jaw of the clamp wherein the clamp further comprises a rear end that is coupled to an end of the bottom jaw and an end of the top jaw and wherein the top jaw further comprises a raised portion; d. coupling the top jaw to a top portion of the solar panel module; e. turning a binding bolt clockwise around the elongated portion until the turning of the binding bolt:
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; and
ii. creates a downward force applied to the top jaw that causes the raised portion on the top jaw to penetrate an outer surface layer of the solar panel module, thereby creating an electrical bonding path between the solar panel module and the rail support through the clamp.

17 . The method of claim 16 wherein the top jaw, rear end, and bottom jaw comprise a generally c-shaped structure.

18 . The method of claim 16 wherein the top jaw further comprises a flange extending from the rear end and has a length that is greater than the length of the lower jaw.

19 . The method of claim 16 wherein the elongated bolt of the t-bolt is threaded.

20 . The method of claim 16 wherein the clamp assembly is made from an electrically conducting material.

21 . The method of claim 16 wherein the binding bolt further comprises a nut on an end of the binding bolt such that the nut further comprises a serrated flange and further comprises the step of turning the nut until the serrations penetrate the top jaw.
