Fire pit and method of use
A pyramid fire pit. The fire pit includes a first trapezoidal side plate having a first hook and a first slot defined in opposing upper corners, a second trapezoidal side plate having a second hook and a second slot defined in opposing upper corners, and a third trapezoidal side plate having a third hook and a third slot defined in opposing upper corners. The first hook locks into the second slot, the second hook locks into the third slot, and the third hook locks into the first slot so that the three side plates define between themselves an inverted triangular pyramid-shaped cavity in which a fire can be built.
1. A pyramid fire pit comprising:
a first trapezoidal side plate having a first hook and a first slot defined in opposing upper corners;

a third trapezoidal side plate having a third hook and a third slot defined in opposing upper corners,
the first hook locked into the second slot, the second hook locked into the third slot, and the third hook locked into the first slot whereby the three side plates define therebetween an inverted triangular pyramid-shaped cavity;
wherein each side plate has an upper edge extending between its opposing upper corners, a lower edge shorter than the upper edge, a first intermediate edge forming approximately right angles with the upper and lower edges, and a second intermediate edge forming an acute angle with the upper edge and an obtuse angle with the lower edge.
2. The pyramid fire pit of claim 1 wherein:
the first slot is formed in the first side plate adjacent the right angle between the upper and first intermediate edges; and
the first hook is formed in the first side plate adjacent the acute angle between the upper and second intermediate edges.
3. The pyramid fire pit of claim 1 wherein the first side plate defines a plurality of air openings.
4. The pyramid fire pit of claim 1 wherein the three side plates comprise sheet steel.
5. The pyramid fire pit of claim 1 and further comprising a triangular-shaped floor plate sized to fit into the inverted pyramid-shaped cavity at an intermediate point between an apex of the cavity and a base of the cavity.
6. The pyramid fire pit of claim 5 wherein the floor plate defines an air opening.
7. The pyramid fire pit of claim 6 and further comprising:
a gas burner element; and
a support pipe coupled to the gas burner element and in fluid-flow connection with the gas burner element, the support pipe disposed in the opening in the floor plate.
8. A pyramid fire pit comprising:
a first trapezoidal side plate having a first hook and a first slot defined in opposing upper corners;
a second trapezoidal side plate having a second hook and a second slot defined in opposing upper corners; and
a third trapezoidal side plate having a third hook and a third slot defined in opposing upper corners,
the first hook locked into the second slot, the second hook locked into the third slot, and the third hook locked into the first slot whereby the three side plates define therebetween an inverted triangular pyramid-shaped cavity;
a triangular-shaped floor plate (i) sized to fit into the inverted pyramid-shaped cavity at an intermediate point between an apex of the cavity and a base of the cavity; and (ii) defining an opening;
a gas burner element comprising three straight pipes containing gas orifices, connected at their ends to define a triangular shape; and
a support pipe coupled to the gas burner element and in fluid-flow connection with the gas burner element, the support pipe disposed in the opening in the floor plate.
9. The pyramid fire pit of claim 1 and further comprising a triangular cover sized to fit over the upper edges of the three side plates.
10. The pyramid fire pit of claim 1 and further comprising a triangular grill sized to fit over the upper edges of the three side plates, the grill comprising a frame and a plurality of grill elements disposed across the frame.
11. A pyramid fire pit comprising:
a first trapezoidal side plate having a first hook and a first slot defined in opposing upper corners;
a second trapezoidal side plate having a second hook and a second slot defined in opposing upper corners; and
a third trapezoidal side plate having a third hook and a third slot defined in opposing upper corners,
the first hook locked into the second slot, the second hook locked into the third slot, and the third hook locked into the first slot whereby the three side plates define therebetween an inverted triangular pyramid-shaped cavity;
a triangular grill sized to fit over the upper edges of the three side plates, the grill comprising a frame and a plurality of grill elements disposed across the frame; and
an auxiliary grill supported above the triangular grill by a plurality of support rods that rest on the frame of the triangular grill.
12. The pyramid fire pit of claim 11 wherein the auxiliary grill is triangular in shape.
13. The pyramid fire pit of claim 1 and further comprising a triangular pyramid-shaped spark arrestor shaped to fit over the upper edges of the three side plates.
14. A pyramid fire pit comprising:
a first trapezoidal side plate having a first hook and a first slot defined in opposing upper corners;
a second trapezoidal side plate having a second hook and a second slot defined in opposing upper corners; and
a third trapezoidal side plate having a third hook and a third slot defined in opposing upper corners,
the first hook locked into the second slot, the second hook locked into the third slot, and the third hook locked into the first slot whereby the three side plates define therebetween an inverted triangular pyramid-shaped cavity; and
a triangular pyramid-shaped spark arrestor shaped to fit over the upper edges of the three side plates and comprising three triangular-shaped panels each having a frame and a wire mesh disposed in the frame.
15. The pyramid fire pit of claim 14 and further comprising a detachable hinge connecting a first one of the panels with a second one of the panels.
16. The pyramid fire pit of claim 14 wherein a first one of the panels has a lower lip shaped to fit over the upper edge of one of the trapezoidal side plates.
