Definitions

  • the present invention relates to fenestration units such as windows and, more particularly, to window screens that screen a window opening when a window is opened and do not screen the window opening when the window is closed.
  • Residences include many fenestration units such as windows and doors. These fenestration units can be access corridors for insects and other debris into a residence. Typical fenestration units provide lackluster results for inhibiting insects and debris from entering the residence.
  • typical window assemblies include a pair of double hung windows and a separate screen connected to the window frame or residence externally of the window in an attempt to inhibit insects and debris from entering the residence.
  • the screen When viewing through the window, the screen is always visible. The visible screen obstructs viewing capabilities and is a detriment to viewing quality.
  • the screen is always exposed to the elements and insects, debris, dirt, or other contaminants can accumulate on the screen further deteriorating viewing quality.
  • screens are often removed and stored when not desired. During removal and storage of the screens, the screens can be damaged, thereby requiring costly and timely repair or replacement of the screens. Storage of the screens can also consume vast quantities of space that could otherwise be utilized.
  • many other problems exist with conventional fenestration units and, more particularly, with windows and screens.
  • a fenestration unit such as a window assembly
  • the window assembly provides an "all-in-one" window including a window screening assembly that does not substantially affect the exterior appearance of the window assembly and provides a glass-only view when the window is in a closed position.
  • the window screening assembly is almost imperceptible from the interior of the window as well.
  • the window assembly eliminates the need to put-up and take-down screens.
  • the window assembly provides an insect barrier comparable to a typical whole-window screen. Further yet, the window assembly decreases the need to clean screens due to a self-cleaning function.
  • window screening assembly due to the configuration of the window screening assembly, tilting of a window for glass cleaning purposes is not complicated by the addition of the window screening assembly. Life of the screen can be increased by the window screening assembly due to the storage of the screen away from the elements during non-use of the window screening assembly.
  • a double-hung window assembly is provided with similar upper and lower sliding windows.
  • a spring-loaded screen roller is positioned in a window sash of each of the upper and lower windows.
  • a spring-loaded screen roller is positioned in one of the window sashes, while the other screen roller is positioned in one of the window frame or a roller housing connected to the window frame.
  • the spring-loaded screen roller has a window screen rotatably supported thereon and the screen is extendable from and retractable onto the screen roller as the window is opened and closed, respectively, to provide a glass only view when the window is closed and a screened window when the window is open.
  • the upper and lower windows can be moved to a particular height to position them in a tilting position.
  • a window assembly provides an after-market window screening assembly retrofitable to a large variety of previously installed windows.
  • the after-market window screening assembly can assume a large variety of configurations to facilitate adaptation to the large variety of windows (e.g., single-hung windows, double-hung windows, bi-pass (slider) windows). This after-market window screening assembly operates in much the same manner as the previously described window screening assembly.

  • the tilting bracket 86 When the window 34 is raised to a height where the tilting bracket 86 is at substantially the same height as the recess 96, the tilting bracket 86 can leave the track 92 and rotate within the recess 96. Since the recess 96 is not movable, the tilting bracket 86 and the window 34 can only tilt when positioned at substantially the same height as the recess 96. In some embodiments, the window is moved to a standard height of six inches to enable the tilting feature. Alternatively, other heights can be used as the height for enabling the window tilting feature. In addition, multiple recesses 96 can be defined in the window frame 40 to allow the window 34 to tilt at various heights. A safety locking mechanism can be used to selectively lock the window at the window tilting height. An example of a safety locking mechanism will be described in greater detail below with reference to Figs. 29-33.

When both upper and lower windows 32, 34 are closed, the felt seals 100 sealingly engage the sash 46 of the other window 32, 34. The seal that is formed keeps bugs and debris from passing between the windows 32, 34 that would have otherwise been stopped by a typical non-retractable screen.

Abstract

L'invention concerne un module de fenêtrage et un ensemble grillage-moustiquaire. Le module de fenêtrage peut être un ensemble fenêtre supportant une variété de fenêtres telles qu'une fenêtre à guillotine à un châssis mobile, une fenêtre à guillotine à deux châssis mobiles ou une fenêtre coulissante à deux vantaux. L'ensemble fenêtre peut comprendre un ensemble grillage-moustiquaire de fenêtre soit fabriqué avec la fenêtre soit produit après fabrication. L'ensemble fenêtre peut comprendre un rouleau de grillage-moustiquaire à ressort pour enrouler et dérouler un grillage-moustiquaire au niveau du rouleau. La fenêtre supérieure et la fenêtre inférieure peuvent pivoter dans une résidence lorsqu'elles sont ouvertes selon un certain degré. Les fenêtres peuvent pivoter autour du même axe autour duquel le rouleau de grillage-moustiquaire tourne, ceci minimalisant tout changement de position et de tension du grillage-moustiquaire quand les fenêtres sont basculées. Une garniture d'étanchéité peut être mise en œuvre pour fermer l'espace entre fenêtres quand les fenêtres sont dans une position quelconque. De plus, un organe d'enclenchement du grillage-moustiquaire peut être mis en œuvre pour empêcher tout déroulement accidentel du grillage-moustiquaire par rapport au rouleau.
