ABSTRACT:
An open-fronted refrigerated display case permitting shoppers direct access to goods displayed therein which also allows loading thereof by the movement of a loaded cart into a stationary location within the display case from the front direction or the rear direction, the case including a stationary housing which defines a refrigerated enclosure which further defines a front opening and a rear wall area and a case floor, the front opening having an air curtain extending thereover created by the passage of refrigerated air from air outlets along the upper edge of the front opening to air inlets along the lower edge of the front opening, also including an air circuit means to communicate the air from the inlet to the outlet and through the refrigeration device to form the air curtain from refrigerated air, also including a door means extending over at least a portion of the rear wall area with the remainder of the rear wall area covered by a curtain means, the door means being mounted within at least one track and the insulating curtain being mounted immediately adjacent the single track such that the door is slidably mounted within the track and when moved to an open position the curtain collapses allowing entry of the movable cart from the rear direction, and when the slidably mounted door is closed the curtain will expand to isolate the environment within the refrigerated case from the external environment, the case also including vertical air conduits within the hollow rear doors to aid in the communication of air from the air inlets at the bottom of the open front to the air outlets at the top of the open front, the movable carts adapted to be moved into the refrigerated enclosure from the rear direction through the door means or from the front direction through the open front area.
