1. A wheeled cart, comprising:
a basket assembly configured to transport a variety of objects placed within;
a left front wheel, a right front wheel, a left rear wheel and a right rear wheel each rotatably attached to the basket assembly, wherein the left rear wheel and the right rear wheel are aligned along a common rear axis;
a left brake lever arm pivotably attached to the basket assembly and pivotable about a left brake lever arm axis, wherein the left brake lever arm includes a left brake lever arm distal end extending perpendicularly in relation to the left brake lever arm axis, wherein the left brake lever arm is configured to pivot by engaging the left brake lever arm distal end between a released position and a braked position, wherein the left brake lever arm includes a left brake feature;
wherein on an inside face of the left rear wheel includes a plurality of stops radially disposed about the common rear axis;
wherein in the braked position the left brake feature is configured to be positioned between at least two of the plurality of stops of the left rear wheel preventing rotation of the left rear wheel;
wherein in the released position the left brake feature is configured to be positioned outside the plurality of stops allowing rotation of the left rear wheel;
a right brake lever arm pivotably attached to the basket assembly and pivotable about a right brake lever arm axis, wherein the right brake lever arm includes a right brake lever arm distal end extending perpendicularly in relation to the right brake lever arm axis, wherein the right brake lever arm is configured to pivot by engaging the right brake lever arm distal end between the released position to the braked position, wherein the right brake lever arm includes a right brake feature;
wherein on an inside face of the right rear wheel includes a plurality of stops radially disposed about the common rear axis;
wherein in the braked position the right brake feature is configured to be positioned between at least two of the plurality of stops of the right rear wheel preventing rotation of the right rear wheel; and
wherein in the released position the right brake feature is configured to be positioned outside the plurality of stops allowing rotation of the right rear wheel;
wherein the left brake lever arm includes a left side raised bump and wherein the basket assembly includes a left side flexure formed by a left side elongated slot, the left side elongated slot extending from a left side first slot end to a left side second slot end, the left side flexure at least partially extending towards the left brake lever arm axis;
wherein the left side raised bump is disposed within the left side first slot end or the left side second slot end and the left side flexure is not engaged by the left side raised bump when the left brake lever arm is in either the released position or the braked position; and
wherein the left side flexure is engaged by the left side raised bump when moving between the released position and the braked position;
wherein the right brake lever arm includes a right side raised bump and wherein the basket assembly includes a right side flexure formed by a right side elongate slot, the right side elongated slot extending from a right side first slot end to a right side second slot end, the right side flexure at least partially extending towards the right brake lever arm axis;
wherein the right side raised bump is disposed within the right side first slot end or the right side second slot end and the right side flexure is not engaged by the right side raised bump when the right brake lever arm is in either the released position or the braked position; and
wherein the right side flexure is engaged by the right side raised bump when moving between the released position and the braked position.
