ABSTRACT:
A shopping cart that utilizes two pivotably connected tubular frames, each frame having two spaced apart legs with an axle carrying wheels extended between them. These frames are pivotably connected in a way which permits the movable frame to be tilted backward thus lifting the front wheels of the cart, and making the cart capable of climbing stairs. When not in use, the whole cart can be easily folded in a space saving unit convenient for storage in a small closet or the like.
