Support system for photovoltaic mounting rail having cylindrical base that rotates into a locked position

1. An assembly for supporting a photovoltaic mounting rail, comprising:

a mounting bracket having a slot passing therethrough;

a support bolt having a T-shaped head configured to pass through the slot in the mounting bracket and a locking projection, the locking projection being configured to rotate into a locked position within the slot;

a support body receivable around the support bolt, wherein rotation of the support body causes the locking section of the support bolt to rotate into the locked position within the slot; and

an upper mounting base positioned on top of the support body, the upper mounting base being attached to the support bolt, and the upper mounting base being configured to interface with a side surface of a mounting rail.

2. The assembly of claim 1 , wherein the support body is cylindrical.

3. The assembly of claim 1 , wherein the support body has a support core configured to receive the support bolt.

4. The assembly of claim 1 , wherein the mounting bracket is dimensioned to wrap over a roof batten.

5. The assembly of claim 1 , wherein the mounting bracket has a raised center portion and two lowered end portions, and wherein the slot passes through the raised center portion.

6. The assembly of claim 1 , wherein the upper mounting base is rotatable on the support body.

7. The assembly of claim 3 , wherein the support core pushes against the locking portion of the support bolt when the support body is rotated.

8. The assembly of claim 1 , wherein the support bolt is configured to rotate ninety degrees from an unlocked to a locked position.

9. The assembly of claim 1 , wherein the support body is substantially hollow.

10. The assembly of claim 1 , wherein the support body has internal flanges extending inwardly from the support body configured to wrap around the support bolt.

11. The assembly of claim 1 , wherein the upper mounting base is secured through the support body to the mounting bracket via a support nut screwed onto the support bolt passing through the support body.

12. The assembly of claim 1 , further comprising a gasket positioned between the support body and the upper mounting base.

13. The assembly of claim 1 , wherein the upper mounting base comprises a vertical projection having a vertical slot therein.

14. The assembly of claim 13 , wherein the vertical projection has a ridged surface for positioning a groove nut and groove bolt received through the vertical slot.

15. The assembly of claim 13 , wherein the groove bolt passing through the slot in the vertical projection is received into a side groove in a mounting rail.

16. The assembly of claim 13 , further comprising a retaining ring received around the groove bolt, the retaining ring having ring-arms extending therefrom that are aligned with a T-shaped end of the groove bolt.

17. The assembly of claim 1 , wherein the mounting bracket includes bracket holes configured to receive rafter bolts that have a shaft diameter of about four millimeters.

18. The assembly of claim 1 , wherein the mounting bracket includes six or more paired bracket holes.

19. The assembly of claim 1 , wherein the mounting bracket is an arc-bracket.

20. The assembly of claim 1 , wherein the mounting bracket is a U-bracket.
