The invention also provides for a guide mechanism for guiding a flexible curtain in a door opening, wherein the guide mechanism includes first and second guide members arranged on at least one vertical side of the door opening. An extension is arranged at an upper end of each of the first and second guide members. A vertical track for guiding an edge of the flexible curtain is defined between the first and second guide members. A tapered expanded portion of the track is defined between the extensions of the first and second guide members. At least one of the first and second guide members includes a semirigid frame plate. The semirigid frame plate includes at least one wall which is capable of undergoing an elastic deformation under pressure of an external force and is capable of returning to an original position without damage. At least one of the extensions being elastically flexible and capable of deflecting out of an initial position.
