Height adjustment bracket for roof applications
A roof mount system supports a solar panel above a roof and includes a base positioned on the roof and a first fastener connected to the base and extending away from the roof and moveable along the base in a direction generally parallel to the roof. A first clamp supports a bottom surface of a solar panel frame and adjusts the height of the solar panel above the roof by moving the first clamp along a first fastener in a direction perpendicular to the roof. A second clamp is connected to a second fastener and moves with respect to the first clamp perpendicular to the roof. The solar panel is clamped between the first clamp and the second clamp portion. A protrusion extends from the first or second clamp to form an electrical bond between the solar panel frame and the respective first or second clamp.
1. A roof mount, comprising:
a base installable on a roof;
an adjustment assembly operatively coupled to the base, the adjustment assembly comprising a threaded shaft extending along a first axis substantially perpendicular to the roof and a nut constrained within the adjustment assembly;
a clamp adjustably connected to the base by the adjustment assembly, wherein a distance between the clamp and the base is adjustable, the clamp comprising:
a first clamp portion that includes a central portion, a first support surface and a second support surface,
the first support surface comprising a recess and configured to support a portion of a first solar panel,
the central portion disposed between the first support portion and the second support portion;
a second clamp portion
a fastener connected to the clamp, the fastener operable to tighten the second clamp portion to the first clamp portion; and
an access to enable adjustment of the clamp along the first axis, the access defined through the second clamp portion.
2. The roof mount of claim 1 , wherein the adjustment assembly is slidable on the base.
3. The roof mount of claim 1 , wherein the recess is a curvilinear depression.
4. The roof mount of claim 1 , wherein the central portion defines an aperture that is configured to receive the adjustment assembly.
5. The roof mount of claim 4 , the nut comprises a protrusion that is configured to contact and support the first clamp portion.
6. The roof mount of claim 1 , wherein the clamp comprises a resilient wall defined in the central portion.
7. The roof mount of claim 1 , wherein the second portion is configured to support a portion of a second solar panel.
8. A roof mount comprising:
a base extending along a second axis;
an adjustment assembly operatively coupled to the base, the adjustment assembly comprising a threaded shaft extending along a first axis substantially perpendicular to the second axis and a nut constrained within the adjustment assembly;
a clamp adjustably connected to the base by the adjustment assembly, wherein a distance between the clamp and the base is adjustable, the clamp comprising:
a first channel sized to receive and support a first solar panel, the first channel defined between a first top flange and a first bottom flange, the first bottom flange including a recess, the first channel having a first height extending between the first top flange and the first bottom flange, the first height being adjustable; and
a second channel sized to receive and support one of a second solar panel, the second channel defined between a second top flange and a second bottom flange, the second channel having a second height extending between the second top flange and the second bottom flange, the second height being adjustable;
a central portion disposed between the first bottom flange and the second bottom flange, the central portion comprising a slot having an open side facing the base; and
a first fastener connected to the clamp, the first fastener operable to adjust the first height and second height; and
an access to enable adjusting of the clamp along the second axis, the access defined through the central portion.
9. The roof mount of claim 8 , wherein the recess is a curvilinear depression.
10. The roof mount of claim 8 , wherein the slot of the central portion is configured to receive the adjustment assembly.
11. The roof mount of claim 10 , wherein the nut comprises a protrusion that is configured to contact the central portion.
12. The roof mount of claim 10 , wherein the nut is retained in the slot by an insert.
13. The roof mount of claim 8 , wherein the clamp comprises a wall disposed between the first channel and the second channel.
