ABSTRACT:
A weather sealing arrangement for a gap between first and second elongate structural members of which a door equipped with a weatherboard, and a sill, are examples, in which the weatherboard supports an elongate seal therealong which has a resiliently supported protruding portion for sealing a gap between the weatherboard and the sill when the door is in a closed condition, and the sill provides a weather strip which extends along the sill and protrudes therefrom. During hingeing movement of the door from the closed condition to an open condition, the protruding seal passes through an intermediate condition in which the seal portion traverses the weather strip so that the whole length of the seal portion is wiped by the weather strip and rainwater will tend to be wiped off the seal portion and so be kept outdoors. The weather strip is in the form of a rib which may be elastomeric and removably secured to the sill, or formed on it and be moulded with the sill. In the closed condition the seal portion and rib may be backed up by the door; the seal portion may seal against the rib, or the sill, or both the rib and the sill.
