Abstract

The collapsible shopping cart device provides a shopping cart with pivoting telescopic legs. Two spaced apart front legs mount to a pair of spaced apart leg pivots proximal to the basket bottom front. The pivoted legs provide for total collapse to the basket bottom or extension to positions that allow the basket to be selectively varied in height above a given surface such as a store floor. The basket may be provided with hinges between the basket sides and front and back and the basket bottom such that sides, front, and back may collapse for even greater collapsibility for either transport or storage. The sides, front and back are selectively locked in place when expanded. The seat bottom and back may be removable. The handle may be removable. The entire basket and its upwardly disposed components may therefore provide extreme compactability.
