Abstract: A convertible door structure for hinged mounting in a conventional door frame and including bottom and upper panel portions normally bounded by opposed side stiles and top and bottom cross rails; the lower panel portion is fixed relative to the lower portions of the side stiles and the bottom cross rail. The upper panel portion is hinged along its bottom edge to the top edge of the bottom panel portion in a manner whereby it may be swung from its normal closed position, relative to the top halves of the side stiles and the top cross rail to an open position wherein it overlies the inner face of the bottom panel portion. A pocket or well is defined within the lower panel portion to store a generally conventional type of framed screen unit for selective removal and installation in the opening defined in the upper portion of the door when the upper panel portion is disposed in its down position.
