Abstract
The present invention would be a collapsible shopping cart fabricated from plastic or metal. The front and rear sides of the shopping cart of the present invention would be connected to a lower frame at pivot points, allowing the sides to fold down against the lower frame as needed. Four wheels would also be attached to this lower frame. One side of the cart would be curved or rounded at its top, serving as the cart's push handle, with a cross member support bar attached between the outer support arms. The other side of the cart would have additional horizontal support arms attached to the pivot points at the top of its outer support arms, with these horizontal support arms having incorporated hooks at their ends that would allow the horizontal supports to be secured to the cross member support bar on the opposite side of the cart, creating the cart's upper support frame. The present invention would also come with a mesh basket having a solid bottom and attached eyelets at each corner, with this basket being secured to incorporated hooks on each side of the cart.
