<p>The invention relates to a roll-up flexible door that opens and closes vertically and automatically and provides a panic function, comprising: two vertical jambs (2) defining a normal operating plane (P) and a shaft (3) disposed at the upper end of the jambs which can be driven by electromechanical means (5, 6); and a flexible curtain (7) connected to the shaft (3) between a closed position and an open position. According to the invention, the door (1) has been provided with the following elements in order to perform the panic function, namely: a panic contact zone (13) with a mark on one face of the curtain; at least first optoelectronic panic detection means provided on the side of the curtain with the panic contact zone inside a detection plane (P') that is substantially parallel to the normal operating plane (P) forming a detection screen substantially parallel to the panic contact zone, such that contact with the curtain (7) at the panic contact zone (13) cuts off the detection screen (21); and actuation means that can trigger the automatic raising of the curtain (7) into the open position in response to the cutting off of the detection screen, said actuation means including at least one built-in mechanical system facilitating the raising of the curtain.</p> |
