Abstract

A mounting assembly for use in mid-grab and/or edge-grab applications may include a clamp secured to a stanchion by a clamping fastener. The mounting assembly may also include a mounting plate which may be secured to a mounting device by the stanchion. The mounting assembly may be used, for example, to secure photovoltaic modules (or other devices or structures) of varying heights to a roof or other building surface.

First claim

What is claimed is:

1. A mounting system to mount a photovoltaic module to a surface of a building, comprising:
a clamp, comprising:
an upper wall with an aperture, a first surface, and a second surface opposite to the first surface, wherein a medial section of the first surface includes the aperture and defines a first reference plane, and wherein no portion of the clamp intersects the first reference plane;
a first sidewall extending from the upper wall proximate to the second surface; and
a second sidewall extending from the upper wall proximate to the second surface, the first and second sidewalls defining a stanchion receptacle;

a mounting plate with an upper surface and a lower surface;
a stanchion extending from the upper surface of the mounting plate, the stanchion comprising:
a first end spaced from the upper surface of the mounting plate; and
a first threaded hole extending through the first end into the stanchion;

a mounting device comprising a body with:
a top surface to support the lower surface of the mounting plate;
a bottom surface;
a first side surface;
a slot extending into the body through the bottom surface to receive a standing seam extending from the surface of the building; and
a second threaded hole extending through the first side surface to the slot, the second threaded hole configured to receive a seam fastener to engage the standing seam when the standing seam is positioned within the slot; and

a clamping fastener comprising a first threaded shaft;
wherein the aperture of the clamp and the first threaded hole of the stanchion are configured to receive the first threaded shaft of the clamping fastener.

2. The mounting system of claim 1 , wherein:
the first sidewall has a first inner surface;
the second sidewall has a second inner surface; and
a portion of the first inner surface is spaced from a portion of the second inner surface by a distance approximately equal to a width of the stanchion such that at least a portion of one of the first and second inner surfaces contacts at least a portion of the stanchion when the stanchion is positioned within the stanchion receptacle.

3. The mounting system of claim 1 , wherein:
the second surface of the upper wall defines a second reference plane;
the upper wall extends from a first edge to a second edge, the first and second edges being closer to the second reference plane than to the first reference plane;
the first sidewall extends from the upper wall and is offset from the first edge by a first edge distance to form a first clamping section; and
the second sidewall extends from the upper wall and is offset from the second edge by a second edge distance to form a second clamping section.

4. The mounting system of claim 1 , wherein:
the mounting plate comprises a hole extending through the upper and lower surfaces;
the stanchion comprises a second end with a second threaded shaft configured to extend through the hole of the mounting plate; and
the mounting device comprises a third threaded hole extending through the top surface and into the body, the third threaded hole configured to receive the second threaded shaft of the stanchion to secure the mounting plate to the mounting device between the second end of the stanchion and the top surface of the mounting device.

5. The mounting system of claim 1 , wherein the mounting plate has an outer perimeter that extends away from the first side surface of the mounting device when the mounting plate is secured to the mounting device.

6. The mounting system of claim 1 , wherein:
the first sidewall comprises:
a first upper end that intersects the upper wall;
a first free end spaced from the upper wall; and
a first intermediate section between the first upper end and the first free end; and

the second sidewall comprises:
a second upper end that intersects the upper wall, the second upper end separated from the first upper end by a first interior distance;
a second free end spaced from the upper wall, the second free end separated from the first free end by a third interior distance; and
a second intermediate section between the second upper end and the second free end, the second intermediate section separated from the first intermediate section by a second interior distance, wherein the first interior distance is greater than the second interior distance, and wherein the second interior distance is greater than the third interior distance.

7. The mounting system of claim 1 , wherein the stanchion further comprises a body portion including:
the first end, wherein the first end is positionable within the stanchion receptacle of the clamp;
a first flat surface oriented approximately perpendicular to the first end; and
a second flat surface positioned opposite to the first flat surface, wherein the first threaded hole of the stanchion extends into at least a portion of the body portion between the first and second flat surfaces.

8. The mounting system of claim 1 , wherein the upper wall further comprises:
a first edge; and
a second edge, wherein the first surface of the upper wall comprises:
the medial section;
a first edge section that extends from the medial section and away from the first reference plane to the first edge; and
a second edge section that extends from the medial section away from the first reference plane to the second edge.

9. The mounting system of claim 1 , wherein, when the clamp is secured to the stanchion by the clamping fastener:
a first free end of the first sidewall of the clamp is positioned between the upper wall of the clamp and the mounting plate; and
a distance between the second surface of the clamp and the upper surface of the mounting plate decreases as the clamping fastener is rotated to advance the first threaded shaft of the clamping fastener into the first threaded hole of the stanchion.

10. The mounting system of claim 1 , wherein:
the first sidewall extends a first sidewall length to a first free end and comprises a first outer surface;
the second sidewall extends a second sidewall length to a second free end and comprises a second outer surface;
the first outer surface is separated from the second outer surface by a first outer distance proximate the upper wall; and
the first outer surface is separated from the second outer surface by a second outer distance proximate to the first and second free ends, the first outer distance being greater than the second outer distance.

11. A mounting system selectively engageable to a standing seam extending from a surface of a building, comprising:
a mounting plate comprising an upper surface and a lower surface;
a stanchion comprising a body portion extending away from the upper surface, the body portion comprising:
a first end spaced from the upper surface by a first stanchion length; and
a first threaded aperture extending through the first end into the body portion;

a clamp comprising:
an upper wall with an aperture therein and a first surface that defines a first reference plane, wherein no portion of the clamp intersects the first reference plane;
a first sidewall extending from the upper wall to a first free end, the first sidewall comprising a first exterior surface and a first intermediate section between the upper wall and the first free end; and
a second sidewall extending from the upper wall to a second free end, the second sidewall comprising a second exterior surface and a second intermediate section between the upper wall and the second free end, wherein the second exterior surface is spaced from the first exterior surface by a first outer distance proximate to the upper wall, wherein the second exterior su
