Patent ID: 7086395

Claim:
A barbeque grill assembly comprising: a base unit including a base plate having a top side, defining a central reference plane that is transverse to said top side and that extends in a first direction, and further having a pair of lateral sides opposite to each other in the first direction, and a pair of leg coupling seats provided respectively on said lateral sides of said base plate, each of said leg coupling seats having a bottom side formed with a pair of insert grooves that are spaced apart from each other in a second direction transverse to the first direction and that are disposed on opposite sides of the central reference plane, each of said insert grooves having inner and outer groove walls respectively proximate to and distal from the central reference plane, said inner groove wall including a first inclined wall section that inclines upwardly toward the central reference plane; a barbeque grill mounted on top of said base unit; and a pair of leg units, each of which includes a pair of leg members and a foldable stretcher interconnecting said leg members, each of said leg members having an upper insert end inserted removably into a corresponding one of said insert grooves in a respective one of said leg coupling seats, said leg units being operable so as to be disposed from a removable state, in which said stretcher of each of said leg units is folded to bring said leg members of each of said leg units closer to each other and in which said leg members of said leg units are generally upright such that said outer groove walls and said first inclined wall sections of said inner groove walls of said insert grooves do not hinder movement of said insert ends of said leg members of said leg units into and out of said insert grooves, to a supporting state, in which said leg members of each of said leg units are moved apart so as to unfold said stretcher of each of said leg units and so as to enable said insert ends of said leg members of said leg units to abut against said outer groove walls and said first inclined wall sections of said inner groove walls of said insert grooves, thereby preventing removal of said base unit from said leg units; wherein said inner groove wall of each of said insert grooves further includes a first straight wall section that extends downwardly from said first inclined wall section and that is parallel to the central reference plane.
