  • ABSTRACT A hermetically sealed dual light window unit in which, if desired, the volume between the lights is allowed to breathe. Each window is provided with structure for allowing the window to be tilted into the building so that the outer light m'ay be cleaned, desiccant can be 52 us. Cl 49/401, 49/484, 52/172 replaced, In an installation comprising a plurality [51] Int.
  • window units also pose two major problems moisture control and pressure compensation. lf the air trapped within the sealed air space between the glass panels contains even a small quantity'of water vapor, changes in air temperature and pressure within the air space and changes in the temperature of the lights themselves may cause condensation to form on the inner faces of the lights and frame. Repeated or extended exposure to moisture leads to the deposit of unsightly film or scum on the glass surfaces; such moisture also tends to attack the frame material and may lead to the deterioration and eventual destruction of the vital glazing gasketsand sealant.
  • Distortion in window glass is created by variations in pressure on the opposite sides of the glass.
  • the pressure on the outside of a window in a building wall is created and controlled only by atmospheric conditions.
  • the pressure on the interior of the window is controlled by those same atmospheric conditions, to some extent, as well as by air conditioning units, elevators moving up and down within the building, etc.
  • steps are taken in the manufacture of such units to avoid the introduction of moisture into the air space before it is sealed. Any moisture inadvertently trapped within the sealed unit is removed by providing a desiccant material in the air space.
  • This desiccant serves, in addition, to absorb the miniscule amount of moisture that invariably manages to migrate into the air space from various sources. If sufficient desiccant is used, as long as the unit remains hermetically sealed protection is afforded for many years against condensation and moisture-induced scum formation or deterioration. Eventually, however, even in the most effectively sealed units the desiccant becomes saturated and free moisture begins to accumulate.
  • the present invention relates to such a multiple light window which has all of the desired features of the presently available windows and which may be easily and quickly opened or removed by authorized workmen to eliminate the disadvantages described above.
  • the invention further relates to such windows and their connection and use with a common manifold system to which a plurality of the windows are ducted.
  • the invention relates to such a window in which a pair of lights may be mounted within a subframe.
  • the sub-frame may, in turn, pivot on a main frame which may be mounted in the wall of the building. Relative movement between the frames allows the exterior light to be worked on without requiring elevator rigs or scaflolding.
  • the sub-frame may be hinged to the main frame at a suitable interface and, when the window is closed, may cooperate with a system of seals which prevent the leakage of air, heat, or noise between the main and the sub-frames.
  • a series of seals may be provided at suitable positions, such as at each of the inner and outer edges of the window, in order to be doubly effective.
  • the series of seals which may be provided for the outer portion of the window prevent air, dirt, moisture, etc., from traveling between the exterior of the building and that part of the main frame-surrounding the window when it is in place.
  • the inner set of seals may be installed to prevent such communication between the interior of the building and the area of the main frame about the window. Thus, air, noise, etc., cannot pass in either direction through the window frame.
  • the lights may each be mounted in continuous gaskets within a sub-frame which can be suitably constructed to allow the application of a continuous bead of sealant which substantially encloses the volume between the lights in the manner taught in our abovecited US. Pat. No. 3,685,239.
  • an essentially sealed window unit may be mounted in such a way as to allow the window to be quickly and easily opened so that the exteriors of both lights may be washed from inside the building or the external light can be repaired or replaced. Additionally, if the environmental control systems within the building should fail, the windows may be opened for ventilation. On the other hand, when the windows are closed, dirt, moisture, and noise cannot penetrate from outside to the building interior.
  • the problems previously described relative to penetration of dirt andmoisture into the volume between the lights and the distortion of the outer light due to pressure differentials can also be obviated by the instant invention.
  • the windows may each be connected to a common manifold or breather system of the type described in our US. Pat. No. 3,604,163 issued Sept. 14, 1971 which teachings are hereby incorporated herein.
  • the otherwise hermetically sealed air spaces within all windows or certain groups of windows in a building or group of buildings may be ducted to a common manifold so that pressure variations within the air spaces are transmitted to the manifold.
  • the manifold in turn is ported to the ambient atmosphere, preferably outside of the building in which the window units are installed, through an air dehumidifying and filtering device.
  • it will be suitable to vent the manifold to a space within the same or another building which is located and designed so that it normally has substantially the same pressure as that on the exterior of the building in which the window units are mounted.
  • this device When the pressure within the manifold is greater than the ambient outside pressure, this device permits air to escape to the atmosphere. When ambient outside pressure exceeds the manifold pressure, it permits air to enter the manifold for distribution to the individual window units.
  • the air within the window units and the manifold is continuously exposed to a desiccating material contained in the dehumidifying device. Any moisture in this air migrates under the influence of its partial pressure to the desiccant, where it is absorbed.
  • This desiccating material is positioned in the stream of all fresh atmospheric air drawn into the manifold, and effectively removes any moisture which might otherwise find its way to the individual window units.
  • the dehumidifying and filtering device may be constructed with alternate air-flow paths passing through two or more desiccant towers. Means may be provided for drying the exhausted desiccant in one of these towers while the others are in use.
  • the volume between the lights may be in communication with a central air-cleaning and drying system such as that disclosed in the above cited US. Pat. No. 3,604,163.
  • a central air-cleaning and drying system such as that disclosed in the above cited US. Pat. No. 3,604,163. This might,'for example, be accomplished by providing a flexible hose which would fit between the sub-frame and the main frame so that the sub-frame can be pivoted in and out of the main frame without interrupting the communication of the volume and the central air system.
  • the invention combines the advantages of having a totally hermetically sealed window, an openable window, and a system for compensating for the pressure differences between different window volumes and the outside of the building.
  • use of all of the features of the invention provides an openable, dirt, moisture, and noise shielding window which, when closed, presents an aesthetically appealing,distortion-free reflection to a person standing outside the building because the outer light is not distorted by pressure differences.
  • the invention provides for the use of an easily treated and/or replaced desiccant material for all windows connected to the breather system rather than a distinct desiccant reservoir for each window.
