Abstract:
1. A polymeric retail cart for use in transporting merchandise, comprising: a base unit having an upper side and an underside; front and rear sets of casters coupled to the underside of the base unit; an intermediate set of casters coupled to the underside of the base unit and disposed between the front and rear sets of casters, wherein intermediate casters are offset relative to the front and rear casters, such that the intermediate casters extend outwardly from the base unit further than the front and rear casters to provide a pivoting axis for the retail cart to pivot in a 360 degree manner central to the retail cart; first and second side attachment members operably coupled to and extending from the upper side of the base unit in a generally upright, parallel, laterally spaced-apart relationship, wherein each side attachment member includes an outer frame member comprising an upper crossbar, a lower crossbar and laterally spaced front and rear uprights; a plurality of shelf support members having shelf receiving channels, wherein the shelf support members are disposed between the front and rear uprights of each side attachment member; one or more first engagement members disposed on an interior side of the shelf support members; a plurality of shelving units slideably and removably supported on associated shelf support members of each side attachment member, wherein the shelving units are adapted to laterally slide along the associated shelf support members of each side attachment member to extend beyond the front and rear uprights of the side attachment members in first and second extended positions; wherein the shelving units further comprise abutment portions that extend downwardly from the shelving units, wherein the abutment portions are adapted to abut the one or more first engagement members disposed on the interior sides of the associated shelf support members when the shelving units are in the first or second extended positions, thereby retaining the shelving unit within the retail cart; and wherein the shelf support members are flexibly resilient and adapted to deform outwardly to allow for a shelving unit to be received in the retail cart between associated shelf support members; and a plurality of stabilizers removably and operably coupled to an upright of the first side attachment member at a first end and operably coupled to an upright of the second side attachment member at a second end, wherein the first and second ends of each stabilizer include upper and lower attachment flanges adapted to be received in one of a receiving aperture and a receiving cradle disposed on the uprights of the first and second side attachment members, wherein each upper attachment flange comprises a downwardly extending retaining member; wherein each receiving cradle protrudes from a respective upright and defines a vertical channel which receives a corresponding lower attachment flange; wherein each retaining member of said upper attachment flanges defines a hook that clamps on to a bottom wall of a corresponding receiving aperture of a corresponding upright; and further wherein the upper and lower attachment flanges impart opposing forces on the upright as coupled thereto.
