Abstract
A Serpentine vend rack structure is provided formed of hollow upright wall portions mounted in ported, laterally adjustable brackets over a refrigeration plenum such that the relative spacing between the wall portions is adjustable to accommodate articles of various sizes for vending. A plurality of shaped bosses on opposing wall portions define a serpentine path and include flow parts over a portion of those paths to permit circulation of refrigerated air from the plenum, up through the brackets and wall portions and out through the bosses to chill articles stored in the vend rack prior to vending. The upright hollow wall portions are internally partitioned to preclude the flow of refrigerated air beyond a desired level of the vend rack.
