A utility cart that is capable of being converted into a collapsed position, a flat cart position, a dolly position, and a tilted position. The utility cart generally includes an interconnected frame that includes three sections, namely, a first section connected to a second section by a first joint, with the second section further being connected to a third section by a second joint. The utility cart also includes a fourth section (a base), which has a set of wheels affixed thereto. The utility cart further includes a support arm mechanism that attaches to the second section at a first end and to a bottom portion (of the base) of the utility cart at a second end. The second end of the support arm mechanism may be reversibly securable to a plurality of different points along the bottom portion of the utility cart.

1. A utility cart that is capable of being converted into a collapsed position, a flat cart position, a dolly position, and a tilted position, which comprises: (a) an interconnected frame that comprises three sections, with a first section connected to a second section by a first joint and the second section connected to a third section by a second joint; and(b) a support arm mechanism that attaches to the second section at a first end of the support arm mechanism, and to a bottom portion of the utility cart at a second end of the support arm mechanism, wherein the second end of the support arm mechanism is reversibly securable to a plurality of points along the bottom portion of the utility cart, wherein: (i) securing the second end of the support arm mechanism along the plurality of points along the bottom portion causes a load bearing surface formed by the second section and third section to move forwards or backwards, when the utility cart is in a tilted position; and(ii) the second joint is configured to allow the third section to rotate and reversibly lock into a position that is parallel and contiguous with the second section when the utility cart is converted to the dolly and tilted positions, rotate and reversibly lock into a position that is approximately perpendicular with the second section when the utility cart is converted to the flat cart position, and rotate and reversibly lock into a position that rests adjacent to the second section when the utility cart is converted to the collapsed position. 2. The utility cart of claim 1, wherein the first joint is configured to allow the first section to (a) rotate and reversibly lock into a position that is approximately perpendicular with the second section when the utility cart is converted to the flat cart position, dolly position, or the tilted position; and (b) rotate and reversibly lock into a position that rests on top of the third section when the utility cart is converted to the collapsed position. 3. The utility cart of claim 2, wherein the bottom portion forms a part of a base portion of the utility cart, wherein the base portion comprises a set of wheels. 4. The utility cart of claim 3, wherein the bottom portion comprises a bar that spans at least a portion of the base portion and is positioned in a center area between two sides of the base portion. 5. The utility cart of claim 4, wherein the first end and the second end of the support arm mechanism each comprise a hinge. 6. The utility cart of claim 5, wherein the second end of the support arm mechanism surrounds and is configured to slide along the bar that forms the bottom portion. 7. The utility cart of claim 6, wherein the second end of the support arm mechanism is prevented from sliding along the bottom portion when in a locked position, wherein a locked position is achieved by actuating a fastening mechanism which locks the second end of the support arm at a desired point along the bottom portion. 8. The utility cart of claim 7, wherein the fastening mechanism comprises: (a) a rotatable knob; or(b) a first aperture located in the second end of the support arm mechanism, a corresponding second aperture located in the bottom portion, and a pin that may be reversibly disposed through the first aperture and second aperture. 9. The utility cart of claim 6, wherein the second end of the support arm mechanism is prevented from sliding along the bottom portion when in a locked position, wherein a locked position is achieved by fastening a stopper at a desired location along the bottom portion, wherein the stopper is configured to prevent the second end of the support arm mechanism from sliding past the stopper in a first direction. 10. The utility cart of claim 9, wherein the stopper is fastened to the bottom portion by: (a) a rotatable knob; or(b) a first aperture located in the stopper, a corresponding second aperture located in the bottom portion, and a pin that may be reversibly disposed through the first aperture and second aperture. 11. The utility cart of claim 10, wherein a first pair of wheels are connected to the base portion and proximate to the first joint, and a second pair of wheels are connected to the base portion and proximate to the second joint when the utility cart is configured in a flat cart position. 12. The utility cart of claim 11, wherein the first pair of wheels exhibit a larger diameter than a diameter of the second pair of wheels. 13. A utility cart that is capable of being converted into a collapsed position, a flat cart position, a dolly position, and a tilted position, which comprises: (a) an interconnected frame that comprises three sections, with a first section connected to a second section by a first joint and the second section connected to a third section by a second joint; and(b) a support arm mechanism that attaches to the second section at a first end of the support arm mechanism, and to a bottom portion of the utility cart at a second end of the support arm mechanism, wherein the second end of the support arm mechanism is reversibly securable to a plurality of points along the bottom portion of the utility cart, wherein: (i) the first joint is configured to allow the first section to (a) rotate and reversibly lock into a position that is approximately perpendicular with the second section when the utility cart is converted to the flat cart position, dolly position, or the tilted position; and (b) rotate and reversibly lock into a position that rests on top of the third section when the utility cart is converted to the collapsed position; and(ii) the second joint is configured to allow the third section to (a) rotate and reversibly lock into a position that is parallel and contiguous with the second section when the utility cart is converted to the dolly and tilted positions, (b) rotate and reversibly lock into a position that is approximately perpendicular with the second section when the utility cart is converted to the flat cart position, and (c) rotate and reversibly lock into a position that rests adjacent to the second section when the utility cart is converted to the collapsed position. 14. The utility cart of claim 13, wherein securing the second end of the support arm mechanism along the plurality of points along the bottom portion causes a load bearing surface formed by the second section and third section to move forwards or backwards, when the utility cart is in a tilted position. 15. The utility cart of claim 14, wherein the bottom portion forms a part of a base portion of the utility cart, wherein the base portion comprises a set of wheels. 16. The utility cart of claim 15, wherein the bottom portion comprises a bar that spans at least a portion of the base portion and is positioned in a center area between two sides of the base portion. 17. The utility cart of claim 16, wherein the first end and the second end of the support arm mechanism each comprise a hinge. 18. The utility cart of claim 17, wherein the second end of the support arm mechanism surrounds and is configured to slide along the bar that forms the bottom portion.
