Jalousie window with daylighting and shading shelf

摘要

A window assembly defines a transom opening above a movably deployable reflective shelf that is positionable to reflect sunlight into the building through the transom, and also can be closed over the transom for protection and/or privacy. The reflective shelf may be associated with a mechanically operated a jalousie window. A plurality of shading shelves may be located on the window below the reflecting shelf and similarly operable to open and close.

1. A window assembly, comprising:
a window frame configured for mounting in an opening in a wall of a building, defining a plane between an inside of the building and an outside of the building; a jalousie structure comprising a plurality of jalousie slats that are one of transparent and translucent and are mounted in the window frame on spaced axes, the jalousie slats being controllably movable toward the plane for closing a space defined by the window frame and pivotable out of the plane for opening spaces between the jalousie slats; a shelf structure comprising a plurality of shelves mounted to said window frame together with the jalousie slats on axes parallel to the spaced axes of the jalousie slats, wherein the shelves are opaque and each of the shelves is controllably movable toward the plane, to close over the space defined by the window frame outside at least two of the jalousie slats that are adjacent to the respective said shelf, wherein the shelves are pivotable out of the plane into a position perpendicular to the plane and extending from the plane toward the outside of the building, each of said plurality of shelves shading a group of at least two jalousie slats that are behind and below the respective said shelf; wherein an uppermost one of the shelves is reflective and covers over an uppermost plurality of the jalousie slats, the uppermost one of the shelves being mounted on an axis spaced below a top of the window frame and operable to pivot toward the plane to a position closing over the window frame and into an open position outward from the plane wherein the uppermost one of the shelves is arranged for reflecting outside light inwardly through the window frame.
