Shopping cart

A shopping cart comprising a frame, an upwardly opening basket secured to the frame, individual caster assemblies separately secured to the frame adjacent the rear corners thereof for supporting the rear end of the frame on a supporting surface, and platform means secured adjacent the front end of the frame, a pair of caster assemblies secured to the platform means in a spaced relationship for supporting the front end of the frame on a supporting surface, said platform means being attached to the front of the frame by a pivot means, said pivot means being constructed and defined for permitting each of the front caster assemblies to be pivotably responsive relative to the other front caster assembly when placed on a supporting surface to thereby be pivotably responsive to any difference in vertical heights of the caster assemblies to pivot the elevated caster assembly downwardly for maintaining substantially the same vertical height as the caster assembly on the opposite side of the platform means to cause both front caster assemblies to substantially continuously engage any type of supporting surface when advanced thereon whereby the pivoting action of the platform means prevents any tendency of the frame to be supported by only one of the front caster assemblies is substantially eliminated.
