Claim:
A self-leveling wheelbarrow comprising: a. a basin having a front end, a rear end, a left side and a right side; b. a wheel disposed beneath said basin near said front end; c. a handle assembly secured to said basin; d. a rear mounting bracket secured near said rear end of said basin, said mounting bracket having a top end secured beneath said basin; e. a leg assembly, said leg assembly comprising a pair of legs secured to one another by a centrally disposed plate, such that one of said pair of legs is positioned beneath said right side of said basin and the other one of said pair of legs is positioned beneath said left side of said basin, said plate further having a centrally disposed, arcuate top edge and a set of teeth arranged along said top edge; f. a means for movably securing said leg assembly plate to said rear mounting bracket, such that said leg assembly may rotate in a counterclockwise or clockwise direction and in a vertical direction relative to said rear mounting bracket; and g. a locking component secured beneath said basin and positioned above said top edge of said leg assembly plate, wherein said locking component is a C-channel member having a pair of adjacent side walls extending downward, each of said side walls further having a tapered edge; whereby as said leg assembly contacts the underlying ground as the wheelbarrow is parked, said leg assembly rotates about said rear mounting bracket to accommodate the contour angle of the ground, sliding said top edge of said plate within said locking component to thereby engage said tapered edges of said locking component within adjacent teeth of said top edge of said leg assembly plate, thereby locking said plate therein to prevent said leg assembly from rotating further, either in a clockwise direction of travel or a counterclockwise direction of travel.
