The unit which may function as a window or door, depending upon the application, is provided with a unique hinge and locking arrangement which facilitates the easy opening and closing of the unit with respect to the opening; yet one which provides security against the unauthorized entry through the opening in that the unit may not be removed from the building opening from the outside of the building when the unit is in a closed position.

Abstract: This invention relates to a shield for windows. More particularly, a confronting double frame window is disclosed which provides improved ventilation and weather shielding for light windows especially useful in mild climates. Conventional single pane glass windows used in such climates when in their closed position, rely on a circuitous path at their weather surface between relatively moving parts for excluding ambient weather, especially wind-driven rain. Such conventional windows include sliding windows with their bottoms riding in a U-section channel and louvered windows having parallel and relatively moving panes of glass which move into and out of juxtaposition with each other in providing ventilation. These types of conventional windows are provided with a second overlying continuous and confronting frame mounted glass panel. This glass panel is held, typically within a frame which is spatially mounted at its periphery, to overlie the border of the conventional window.

Abstract: A mounting frame is adapted to be fixed on one side and is formed with a cavity which is open on the opposite side of said mounting frame. The mounting frame comprises an oblique annular peripheral sealing lip, which protrudes on said opposite side and surrounds said cavity and opposite to said cavity defines an undercut annular peripheral groove. Multi-pivot hinge means are accommodated in said cavity and secured on one side to said mounting frame. A sash is secured to said hinge means on the other side thereof and is movable relative to said mounting frame to a closed position and arranged to sealingly contact said sealing lip in said closed position. Said sash has an annular peripheral channel which is open toward said mounting frame and arranged to receive said sealing lip in said closed position.
