Relay rack
A relay rack includes a base including first and second base brackets. Each base bracket has a vertical base flange attached integrally to a horizontal base flange. First and second support brackets are connected to each base bracket. Each support bracket has a single vertical support and a single horizontal support connected to the vertical support. The support brackets may also include a single vertical end support adapted to be connected to the vertical flange of the base bracket. The vertical support extends along a substantially vertical plane that forms a dihedral angle of less than 90 degrees with the plane of the vertical base flange. In a direction in which the horizontal base flange extends from the vertical base flange, the vertical supports on each base bracket extend convergently toward one another.
1. A relay rack for supporting electrical components, the relay rack comprising:
at least two vertical columns having upper and lower ends;
an upper cross-bracket extending between and attached to the vertical columns at their upper ends; and
a base including:
first and second base brackets, each base bracket having a vertical base flange attached integrally to a horizontal base flange, the vertical base flanges of the base brackets being respectively attached to opposite sides of the lower ends of the vertical columns, the vertical base flanges each extending along a substantially vertical plane, and
first and second support brackets connected to each base bracket, each support bracket having a single vertical support and a single horizontal support connected to the vertical support, the vertical support extending along a second substantially vertical plane that forms a dihedral angle of less than 90 degrees with the plane of the vertical base flange, such that in a direction in which the horizontal base flange extends from the vertical base flange, the vertical supports on each base bracket extend convergently toward one another.
2. The relay rack according to claim 1 , wherein the first and second support brackets are each substantially L-shaped.
3. The relay rack according to claim 1 , wherein the horizontal support of each of the first and second support brackets is welded to the horizontal base flange of the base bracket.
4. The relay rack according to claim 1 , wherein each of the first and second support brackets are connected to the base bracket by a fastener.
5. The relay rack according to claim 1 , wherein the vertical support of each of the first and second support brackets is connected to the vertical flange of the base bracket.
6. The relay rack according to claim 5 , wherein the vertical support of each of the first and second support brackets is welded to the vertical flange of the base bracket.
7. The relay rack according to claim 1 , each of the first and second support brackets further including a single vertical end support connected to the support bracket vertical support.
8. A relay rack for supporting electrical components, the relay rack comprising:

a base including:
first and second base brackets, each base bracket having a vertical base flange attached integrally to a horizontal base flange, the vertical base flanges of the base brackets being respectively attached to opposite sides of the lower ends of the vertical columns, the vertical base flanges each extending along a substantially vertical plane, and
first and second support brackets connected to each base bracket, each support bracket having a single vertical support, a single vertical end support connected to the vertical support, and a single horizontal support connected to the vertical support, the vertical support extending along a second substantially vertical plane that forms a dihedral angle of less than 90 degrees with the plane of the vertical base flange, such that in a direction in which the horizontal base flange extends from the vertical base flange, the vertical supports on each base bracket extend convergently toward one another.
9. The relay rack according to claim 8 , wherein the vertical end support and the horizontal support of each of the first and second support brackets are connected to one of the base brackets.
10. The relay rack according to claim 9 , wherein the vertical end support and the horizontal support are connected to the base bracket by spot welding.
11. The relay rack according to claim 8 , wherein the vertical support of each of the first and second support brackets is tapered from a first height at a first end to a second, smaller height at a second end.
12. The relay rack according to claim 8 , wherein the base brackets and the support brackets are each formed from sheet metal having a thickness less than 0.25 inch.
13. The relay rack according to claim 12 , wherein the base brackets and the support brackets are each formed from 14 gauge sheet metal.
