Abstract
Improvements in the manufacture, mounting and implementation of dry open window (DOW) structures. Such structures comprise a plurality of louvers which, when viewed in cross section, have “V” or “W” shapes that enable air to pass through a window opening while substantially preventing precipitation to pass, the precipitation instead being captured by the louvers for collection or drainage.
Claims26
An environmental window apparatus, comprising:
- a dry open window (DOW) structure having a plurality of louvers which, when viewed in cross section, are formed in the shape of a “V” or “W” that enable air to pass through a window opening while limiting passage of precipitation, the “V” shape disposed with a narrower end pointed downward and two portions sloping upwardly therefrom or the “W” shape disposed with two narrower ends of the shape pointed downward and two portions sloping upwardly from each of the narrower ends such that the precipitation instead is captured by the louvers for collection or drainage;
- and
- a plurality of rigid vertical members supporting the louvers in a spaced apart arrangement;
- wherein the rigid vertical members are adapted to be fixedly supported in a window opening such that the DOW structure is held in a fixed position in an overlying registration with the window opening.

- a plurality of vertical members supporting the louvers in a spaced apart arrangement;
- and
- a plurality of spaced-apart, telescoping rods that span a width of an existing window opening;
- wherein at least some of the plurality of vertical members include a plurality of holes or hooks;
- the holes or hooks engage with the rods to maintain the DOW structure in an overlying registration with the window opening.

- and
- a plurality of vertical members supporting the louvers in a spaced apart arrangement;
- wherein each of the louvers comprises a composite louver having a pair of overlapping upper and lower louver portions, the portions being slidable relative to each other so as to adjust an overall length of the composite louvers;
- wherein the plurality of vertical members includes at least a first side member, a second side member and a central member, the central member supporting the louver portions where they overlap.
