Weathertight door assembly

Image Number 4 for United States Patent #4370827.

A weathertight door assembly having a first sealing means on an outer frame for sealing the gaps between the outer frame and the periphery of a pair of doors when the latter is closed, and a pair of coacting second and third sealing means on one of the doors for sealing the gap between inner vertical frame members of the doors when the latter are closed. A projection extends on and along one of the inner vertical frame members for covering the gap between the doors when the latter are closed. The second sealing means is supported on the projection and coextends with the length therewith. The third sealing means is supported on the said one inner vertical frame member and coextends with the length thereof. As the doors are closed, the third sealing means is sandwiched partly between the second sealing means and the other inner vertical frame member and partly between the latter and the first sealing means.
