Solar panel rack
First Claim
1. A solar panel rack comprising:
- two or more hollow sheet metal beams arranged side by side and in parallel with each other to define a plane;
a transverse support comprising two or more notches located in its upper edge;
two or more first sheet metal brackets, each first sheet metal bracket having an outer cross-sectional shape substantially conforming to an inner cross-sectional shape of a corresponding notch in the transverse support, having an inner cross-sectional shape substantially conforming to the outer-cross sectional shape of a corresponding hollow sheet metal beam, positioned in the corresponding notch in the transverse support, and attached to and supporting the corresponding hollow sheet metal beam at least partially within the corresponding notch in the transverse support;
one or more second sheet metal brackets, each second sheet metal bracket having an inner cross-sectional shape substantially conforming to the outer cross-sectional shape of a corresponding hollow sheet metal beam, positioned on and attached to the corresponding hollow sheet metal beam, and configured to couple to a solar panel or solar panel assembly to position and attach the solar panel or solar panel assembly to the solar panel rack in a desired location in the plane defined by the hollow sheet metal beams;
a hollow sheet metal beam arranged collinearly with one of the two or more side-by-side hollow sheet metal beams; and
an expandable and collapsible sheet metal splice;
wherein the expandable and collapsible sheet metal splice is configured to be bent along predefined bend lines to assume a collapsed configuration, inserted while in the collapsed configuration into adjoining ends of the collinear hollow sheet metal beams, expanded to a configuration having an outer cross-sectional shape conforming to and tightly fitting an internal cross-sectional shape of the collinear hollow sheet metal beams, then attached to both of the collinear hollow sheet metal beams to couple the collinear hollow sheet metal beams to each other;
wherein each hollow sheet metal beam is formed by bending a sheet metal blank comprising preformed tabs and slots configured to secure the sheet metal blank in a beam configuration upon bending of the blank into the beam configuration and comprising preformed slots or other openings configured to predefine the locations at which solar panels or solar panel assemblies are to be attached to the solar panel rack;
wherein the transverse support is formed by bending a sheet metal blank comprising one or more preformed tabs or slots configured to engage one or more corresponding slots or tabs in one of the first sheet metal brackets and each first sheet metal bracket is formed by bending a sheet metal blank comprising one or more preformed tabs or slots configured to engage the one or more corresponding slots or tabs in the transverse support;
wherein each first sheet metal bracket extends beyond the transverse support in both directions along its corresponding hollow sheet metal beam and is progressively less stiff with increasing distance from the transverse support; and
wherein each second sheet metal bracket comprises one or more upwardly pointing tabs configured to contact features on a solar panel or solar panel assembly to position the solar panel or solar panel assembly in a desired location and one or more upwardly pointing tabs configured to be clinched to features on a solar panel or solar panel assembly to attach the solar panel or solar panel assembly to the solar panel rack.

Abstract
A solar panel rack may comprise a vertical support, a transverse support, brackets attaching hollow beams to the transverse support, and brackets configured to attach solar panels or solar panel assemblies to the hollow beams. Internal splices may couple collinearly arranged hollow beams in the solar panel rack. Some or all of these components may be formed from folded sheet metal blanks comprising bend lines predefined by bend-inducing features formed in the blanks. Preformed slots, holes, or other openings in the sheet metal blanks may predefine the relative positions of various components in the solar panel rack and predefine the positions of solar panels or solar panel assemblies to be supported by the solar panel rack. Individual components of the solar panel rack may be useful in other structures and applications apart from solar panel racks.
