ABSTRACT:
A door operating mechanism for use with refrigerated display cases in which provision is made for one or more circulated air bands and an air defrost means. The door operating mechanism functions to selectively create a gap between the barrier door and the associated access opening of the case to carry out defrosting and to also permit the gap to be closed by the application of outside force. A motion take-up means is provided within the door operating mechanism to permit closing of a door through the operation of a flexing means which is preferably a compression spring. Temporary closing of the door gap by customers and employees is operatively provided for by the door operating mechanism.
