Watertight door closure

摘要

A hinged door panel selectively closing an opening within an enclosure wall is held under adjusted watertight pressure by means of a plurality of elongated closure holding devices pivotally mounted on the enclosure by a frame in surrounding relation to the opening. The closure holding devices are selectively displaced from release positions to closure holding positions overlapping sealing contact surfaces formed by wedge elements on the door panel. Wear pads project from the overlapping closure holding devices to engage the contact sealing surfaces on the wedge elements under the adjusted pressure, to effectively seal the enclosure opening in a watertight manner.
