First Claim
1. A modular assembly for use as a fire pit or outdoor grill, said modular assembly comprising:
- (a) a plurality of slab members;
each of said slab members being comprised of an upper surface, a lower surface, an inside surface, an outside surface, a front end surface and a rear end surface;
said upper surface being generally parallel to said lower surface;
said upper surface of said slab member having a first top notch and a second top notch, said first top notch and said second top notch each extending from said outside surface to said inside surface;
said first notch being located in proximity to said front end surface, and said second notch being located in proximity to said second end surface;
said lower surface of said slab member having a first bottom notch and a second bottom notch, said first bottom notch and said second bottom notch each extending from said outside surface to said inside surface;
said first bottom notch being located relative to said front end surface the same as the first top notch, and said second bottom notch being located relative to said second end surface the same as said second top notch;
(b) said slab members being adapted to be assembled wherein there is a bottom course formed by positioning a first pair of said slab members parallel to each other, and separated by a distance equal to the spacing between the first and second notches; and
positioning a second pair of said slab members parallel to each other but cross-wise to said first pair of slab members, and wherein said second pair of slab members are spaced such that said bottom notches in said second pair of slab members dovetail with said top notches of said first pair of slab members;
(c) a plurality of successive courses, each of said successive courses comprising a primary pair of said slab members and a secondary pair of said slab members;
said primary pair of slab members being oriented parallel to said first pair of slab members of said bottom course, and assembled to dovetail with a course below, said course below comprising either said first pair of slab members of said bottom course or a secondary pair of slab members of one of said successive courses; and
positioning said secondary pair of slab members parallel to each other but cross-wise to said primary pair of slab members, and wherein said secondary pair of slab members are spaced such that said bottom notches in said secondary pair of slab members dovetail with said top notches of said first pair of slab members.

Abstract
A modular outdoor barbeque grill and firepit is constructed of artificial stone-like slab members, which permit a uniform construction method by utilizing only a single block with a universal joint configuration to create an easily assembled, disassembled, re-assembled, and inexpensively manufactured product. Simple variation in the slab members'"'"' length, as well as relocation of the joint permits tremendous versatility of product design without increasing complexity of assembly. Slab members are cast of air-entrained concrete in elastomeric molds for reduced density and lighter weight members, which have advantageous thermal properties, exhibit greater longevity in adverse weath conditions, and may be so formed with pigments to resemble stone, brick, or decorative mosaic tile. The ease of construction by the design of this invention also permits quick transition between a backyard fire pit and a barbeque grill with a sophisticated appearance.
