Appl. No.:

12/767726

Inventors:

Jun Liu - Camas WA, US

International Classification:

E04D 13/18

US Classification:

52 58, 126623, 136244, 2482051, 248237, 521733

Abstract:

A system is disclosed for mounting equipment, such as solar panels, to a roof that has shingles. A base plate has at least one mounting aperture therethrough for securing to the roof with a mechanical wood fastener, and at least one bracket projection in an upper surface thereof for securing with a mechanical machine fastener. A flashing plate has a base plate recess formed in a lower surface thereof for receiving the base plate therein. A mounting bracket has at least one aperture therein for receiving one of the bracket projections therethrough for securing the mounting bracket to the at least one bracket projection in the base plate, and through corresponding apertures in the flashing plate. The mounting bracket further includes an attachment aperture adapted to be fixed with the equipment. Additional advantages include using fewer parts by integrating above elements to reduce the costs and steps of installation.

Inventors:

Jun Liu - Camas WA, US

International Classification:

E04D 13/18
E04H 14/00

US Classification:

521733, 411374

Abstract:

Disclosed is an apparatus for mounting equipment or solar photovoltaic structures to roofs where the apparatus base plate engages the roof surface directly, creating a water resistant seal, without the need for flashing. The base plate upper surface includes an upwardly projected portion that is circumscribed by a groove. The base plate lower surface includes a counterbore. Both the counterbore and the groove are disposed to receive annular seals. A threaded fastener is received and seated the upwardly projected portion top surface and feeds through the counterbore, securing the base plate to the roof structure and creates a water resistant seal by compressing the lower annular seal and by creating surface-to-surface contact with the roof and portion of the base plate. An inwardly threaded cover portion engages the upwardly projected portion either directly or through an intermediary, creating a water resistant seal over the fastener.

International Classification:

A47G 29/02
E04G 3/20
E06B 7/28

US Classification:

248237, 52462

Abstract:

Disclosed is an apparatus for mounting equipment, such as solar panels, fans, air conditioning units, walkways, signage, facade, or ladders, on corrugated or ribbed metal roofs where the mounting apparatus attempts to provide a leak resistant and stable mounting structure for such equipment. The corrugated or ribbed metal roof includes one or more peak portions and one or more corresponding valley portions. The equipment-mounting apparatus engages the roof with one or more fasteners at least one peak portion and engages by valley portion through a transfer of force from the fastener at the peak portion without requiring additional fasteners to engage the valley portion.

International Classification:

F16B 43/00
F16B 35/00

US Classification:

4113712

Abstract:

Disclosed is a fastening device for the building construction trade that includes a threaded fastener and a mounting plate. The mounting plate includes a frusto-conical aperture adapted to receive the threaded fastener where the smaller opening of the frusto-conical aperture is on the top surface of the mounting plate where the fastener is seated. The threaded fastener includes a collar portion surrounding the fastener head. The top surface of the mounting plate includes a seating portion surrounding the frusto-conical aperture. The seating portion and the bottom surface of the collar portion are complementary in shape and are both shaped as a section of a spherical surface.

International Classification:

H02S 30/10
F16B 2/12
F16B 2/06

Abstract:

A solar panel racking system that can include end clamps, mid clamps, bottom clamps, L-foot adapter assemblies, rails, and L-foot assemblies. The solar panel racking system minimizes the use of tools by snapping many of the mounting components in place. The end clamps, mid clamps, and bottom clamps can snap over the rail sides and lock into upper detented portions of the rail sides. The upper detented portions are structured to prevent upward movement of the end clamps, mid clamps, and bottom clamps. The L-foot adapter body of the L-foot adapter assembly snaps over lower detented portions of rail sides and secures the rail to an L-foot assembly. The end clamps, mid clamps, bottom clamps, rails, and L-foot adapter assemblies are independent of the L-foot assembly, allowing a selection of L-foot assemblies to be used as appropriate with the solar panel racking system.
