Abstract (en)
[origin: WO0116451A1] The invention relates to an automatic door, especially a sliding door, which is provided with a drive device (2) for opening and closing the door. A metal spring in the form of a flat spiral spring (10) is used as the mechanic energy storage device (9) which stores energy when the door is being closed and releases the stored energy for opening the door when the drive device (2) breaks down. Said spring is arranged around a drive shaft (6) and is under tension when the door is being closed. A rubber rope can be provided instead.
