摘要： The present invention contemplates a closure having primary utility for creating a snug fit between a hangar door and the tail section of an aircraft which projects through the door. In one embodiment, the invention includes carrier support means which are fixed to the hangar door on two opposing sections thereof. Secured to the carrier support means on each side of the opening in the hangar door are aperture carriers, each of which is mounted for movement on the support means toward and away from the other aperture carrier. A slot is formed in the abutting edges of each of the carriers so that when the carriers are adjacent each other, a continuous opening of generally circular cross-sectional configuration is created. Sliding vertically along support means mounted on each of the aperture carriers is an aperture frame which has a semicircular cutout formed thereon to register with the slot formed in the aperture carriers. As in the case of the aperture carriers, the semicircular cutouts formed in the aperture frames are so situated in each of the frames that when the frames abut a circular opening through the planes thereof is formed. Motive means are provided for moving the aperture frames vertically upward and downward with respect to the aperture carriers while similar motive means are provided for moving the aperture carriers toward and away from each other.
