ABSTRACT:
An improved design for a refrigerated display case which significantly enhances airflow characteristics by including a gradual radius within the transition sections in areas where the refrigerated airflow path must change directions to greatly facilitate smooth flow of refrigerated air therethrough. Also disclosed is an improved construction for providing insulation for a refrigerated display case including an inner and outer panel spaced apart to define an insulation holding chamber therebetween and including thermal breakers at the ends thereof for maintaining the panels in spaced relation to each other and for closing off the end section thereof to retain insulation therein. The inner insulation panel defines the outer boundary of the airflow path. Also an improved design for a shelf support standard is positioned within the insulated housing to provide structural strength to the display case apparatus and to support shelving thereon and also to include a case liner secured thereto for defining the inner boundary of the improved airflow path. Thermally non-conductive bolt assemblies are included to attach the insulated foam assemblies to shelf support standards. The design further includes a novel castor configuration to facilitate relocation of the refrigerated display case.
