ABSTRACT:
A Door Control designed especially for a service passage in a quick food establishment or the like, i.e., for serving customers on one side of a passage, say, in a cubicle, by an employee on the other side thereof. Essentially, such control mechanism comprises a device operable by an employee for opening a door or pair of doors normally closing a passage while business may be transacted through the passage such as placing or delivering an order, after which the door or pair of doors is automatically closed. My invention represents an improvement over that disclosed and claimed in my copending application Ser. No. 06/078,095, filed Sept. 24, 1979, now abandoned. In the instant case the doors are so controlled and actuated that, after opening, they are disposed on opposite sides and rearwardly of said passage, not extending substantially forwardly thereof. This feature is of importance in that, if extending forwardly of the cubicle wall, the doors might be subject to possible damage from a moving vehicle; further, in that maximum space is left between the open doors for transaction of business. My invention also contemplates new and improved mechanism for actuating, supporting and retracting the doors most simply and efficiently from closed to open position and reverse.
