Date Aug. 5, 1993.A draught and weather excluder comprising a gap sealing section which enables simple, fast and effective closure of gaps below hinged and sliding doors is disclosed. The sealing section may be simply fitted to the underside of a door edge using strips of bonding tape so that the device may be fitted without removing or modifying the door in anyway. The sealing section comprises two main webs, a mounting web and a sealing web, which are connected together along the length of the section by a hinged or weakened section. The mounting web consisting of a generally thin flat flexible web for flush mounting the sealing section directly to the underside of a door edge. The sealing web consists of a generally curved or non-linear cross section for making contact with and freely sliding over floor surfaces including floor coverings and for actively mounting obstacles on the floor. The sealing web may contain a nose portion extending from the free extremity of the sealing web so as to allow the sealing web to glide freely and smoothly over a floor surface without fouling as the door is rotated in either direction. The nose portion may contain a biasing web extending from its free extremity and extending upwardly and inwardly towards the hinge. The biasing web being able to make contact with the mounting web during upward rotation of the sealing web. The sealing section has a generally constant cross section and may be produced in long lengths of resilient flexible type materials such as plastic.
