ABSTRACT:
A structural latticework frame design, fixed end, cantilevered, or collapsible, on a horizontally openable window, wherein the lattice work frame is used for structural value in the open position. This design allows for the load from the glass and sash to be transferred through the latticework frame to the housing to carry the load, which simplifies the mechanism needed to open and close the window.
