ABSTRACT:
A shopping cart chassis is provided with at least one tubular frame member. At least a first part of the length of the frame member has a wall with a hollow cylindrical configuration defining an annular transverse cross-section. At least a second part of the length of frame member has a wall with a hollow configuration defining an elongate transverse cross-section having a longer dimension and a shorter dimension. A second part of the frame member is oriented so that the longer dimension of the elongate transverse cross-section is generally parallel to the direction of the force of gravity when the shopping cart is in its normal use orientation.
