  • Publication number: 20120144760
    Abstract: A variety of roof mount sealing assemblies are disclosed. The roof mount sealing assemblies allow a user to mount rails for solar panels, signs, satellite dish or any other desired item on the roof and have the mounting location sealed against water. The roof mount sealing assemblies has a body with a recess for a flexible washer, which is attached to a bolt body (or formed with the bolt body) and threaded either down in a base plate or directly into the roof. The bolt body and body form a double stud assembly, which also holds a flashing onto the roof to provide further water proofing.

  • Publication number: 20120097816
    Abstract: A clip for both mounting and grounding photovoltaic panels is disclosed. The clip has retention tabs which interact with mounting rails to fully support photovoltaic panels during installation. The interaction allows for adjustment along the length of the mounting rails. Interlocking fingers allow the mounting clips to fit together securely. The interlocking nature of the mounting clips provides a secure fit between photovoltaic panels and requires less mounting hardware. Additionally, the interlocking nature of the mounting clips allows for security and stability of the photovoltaic panels during the mounting process, allowing a single installer to mount a number of photovoltaic panels. The use of serrated washers, or cutting edges on certain portions of the mounting clip provide grounding for the system by digging into both photovoltaic panels and mounting rails.

  • Publication number: 20120090263
    Abstract: A flashing assembly comprising a base plate, flashing, flashing adapter and O-ring is disclosed. The flashing assembly components fit tightly together, creating a waterproof seal. The flashing assembly has no exposed rubber pieces, which prevents erosion and extends the life of the assembly. The waterproofing and durability of the disclosed flashing assembly make it ideal for enclosing electrical wires and running plumbing needs through the roof or wall membrane. The disclosed flashing assembly is capable of attaching to a number of products, including, but not limited to junction boxes, combiners, and service panels.

  • Publication number: 20100192505
    Abstract: Interlocking support posts form an interlocking rack system which may have a single mold which provides both a male and a female joinder member. Between the support posts can be mounted panels such as solar panels. Under the support posts can be installed a roof stand off assembly which prevents water from weakening the roof. Various combinations of construction members offer a cost effective building block array of mounting panels, wind turbines, and any appliance on a roof and/or anywhere in a building. A two recess mounting bracket is ideally suited to mount solar panels on a roof. A lower recess can be fastened to a bolt anchor on the roof. The opposing recess can secure a mounting clip which attaches directly to the solar panel. Identical support posts can interlock. Various embodiments include conduit clasps, slider tracks, mounts for cabinets, sign posts, and thru roof screwed anchors.

  • Patent number: 6290740
    Abstract: A workbench suited for welding, grinding, and polishing operations features a multi-panel table top. The panels each have a high number of perforations to allow a high rate of air flow at a relatively low noise level. An optional backwall or a booth can be mounted atop the tabletop. Each also has perforations to collect dust from the air flow.
