Abstract: An observation shelter includes a plurality of generally upright walls including a first wall having a first window opening positioned therein and a second wall having a second wall positioned therein. First and second shutters are movable between respective raised and closed positions. The first and second shutters have respective shapes configured such that the shutters when in their respective raised positions meet at a joint extending from said corner to provide substantially continuous shelter from the sun for the first window opening and second window opening, and wherein with the first and second shutters in their respective closed positions, an extension portion of the first shutter is received in a pocket portion of the second shutter.

Abstract: A molded door and mating door jamb for a observation tower enclosure includes a projection to adapt to a non-vertical structure on one side. The door projection is provided to avoid a projecting wall structure experienced by present day door jamb structures in enclosures having glare reducing slanted windows. A generally planar door is hinged to a vertical door jamb on the opposing side, but has a triangular projection on the non-vertical, slanted window side to adapt to the slanted door jamb construction. The door is hinged to open outward and away from the observer's forward area of interest. The molded door avoids a door jamb and adaptor sections which may obstruct the guard's view as he or she opens the door and exits. The molded door can also provide additional structural support for shutters and roof structure when closed. The door can also include seals, locks and windows for added security, protection and visibility.
