Door draught and weather excluder
First Claim
1. In combination,a floor surface;
- a door mounted for movement in a direction parallel to the floor surface, the door having an underside adjacent to the floor surface; and
a gap sealing section for sealing gaps between said underside of the door and the floor surface, the sealing section being secured to the underside of the door, the sealing section having a mounting web on one side directly flush mounted to the underside of the door and a sealing web at the opposite side making contact with and freely and smoothly sliding over said floor surface, the two webs being flexibly connected at one extremity along a line through their length so as to be movable by relative rotation about this line of their connection, the sealing web bearing against the top of the floor surface along a line which is generally below the area defined by the surface of the underside of the door edge.

Abstract
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.

16. A gap sealing section for sealing gaps between the underside of a door edge and the top of a floor surface, the sealing section being securable to the underside of a door edge, the sealing section having a mounting web on one side to allow direct flush mounting to the underside of a door edge and a sealing web at the opposite side for making contact with and freely and smoothly sliding over floor surfaces including floor coverings, the two web being flexibly connected at one extremity along a line through their length so as to be movable by relative rotation about this line of their connection, the sealing web bearing against the top of a floor surface along a line which is generally below the area defined by the surface of the underside of the door edge, wherein the sealing web contains a nose portion extending from the free extremity of the sealing web opposite the line of connection of the sealing and mounting webs and extending through the length of the sealing web, the nose portion being a general extension of the sealing web so as to assist the sealing web in its intended action of gliding freely and smoothly over a floor surface so that the sealing web does not foul with the floor surface, the nose portion being of suitable shape such as generally curved or non-linear shape so as to provide an effective nose to the sealing web so as to assist the sealing web in its intended action of freely and smoothly gliding over a floor surface particularly when the cross sectional curvature of the sealing web may be less acute than the cross sectional curvature of the nose portion or where the sealing web has been significantly rotated downwardly and away from the underside of the door edge so as to expose the free extremity of the sealing web to the line of contact between the sealing web and the floor surface.
- 17. A gap sealing section for sealing gaps between the underside of a door edge and the top of a floor surface, the sealing section being securable to the underside of a door edge, the sealing section having a mounting web on one side to allow direct flush mounting to the underside of a door edge and a sealing web at the opposite side for making contact with and freely and smoothly sliding over floor surfaces including floor coverings, the two webs being flexibly connected at one extremity along a line through their length so as to be movable by relative rotation about this line of their connection, the sealing web bearing against the top of a floor surface along a line which is generally below the area defined by the surface of the underside of the door edge, wherein a biasing web is included, the biasing web extending from the extremity of the sealing web furthest from the line of connection of the sealing and mounting webs and extending upwardly toward the door edge and inwardly toward the line of connection of the sealing and mounting webs.
