Preferably, the collapsible screen means is constructed from sheet plastic, either translucent or clear, and preferably from Mylar?.
Description
WINDOW STRUCTURE
This invention relates to window structures, and in particular, to window structures having built-in fly screens.
It is now common in building construction, especially housing construction, to use prefabricated windows that are secured in place in rough framing, usually prior to application of sheathing on the exterior of the building, and of gypsum board covering on the inside of the building. For convenience, including locks, hinges and fly screens, and often mechanical means for opening and closing the window, such as a crank and linkage.
In warm climates, the fly screen associated with such units is necessary to prevent the entry of undesired insects such as mosquitoes. Indeed, in some climates, the absence of a fly screen would make comfortable occupancy of the building almost impossible.
In my Canadian Patent No. 1,298,518, issued 7 April, 1992 for a WINDOW STRUCTURE, I have disclosed a window having a sash and frame equipped with a fly screen that does not obstruct the view through the window when the latter is open or closed. The disadvantage with this type of window structure is that the fly screen-is rigid and therefore, the depth of the frame and sash must be sufficient to encapsulate the screen when put into the closed position. This is most clearly seen in Figure 3 and Figure 1 of the aforesaid patent. The width or depth of the sash therefore, has to be increased in order to accommodate such fly screen and this adds to costs and is not as pleasing to the eye, when the window is viewed from the outside since the window sash or frame protrudes outwardly from the wall.
It is an ob~ect of the invention to overcome this problem; to reduce the depth of the sash, and yet to provide a collapsible fly screen which, when in the closed position, is essentially non-viewable, while in the open position to provide screening from insects and the passage of airflow through the screen, and always maintaining a clear view through the glass without the impediment of ever having an overcoverlng screen.
This is achieved by having a flexible fly screen structured as an accordion-like member and fabricated from a flexible porous sheet plastic sheet, clear or translucent, shaped as a perforated accordion.
In one embodiment, the invention contemplates that the screen be integral with the sash and window during construction and in another embodiment, can be a retro-fit screen to an existing window and sash, the window being movable to an open position so as to allow airflow into the room and fly protection or screening.
The invention therefore contemplates a window unit comprising a window sash frame, a sash hingeably mounted to said sash frame for pivotal movement between a closed position juxtaposed with the sash frame, and an open position in which a space is defined between the sash frame and sash and, a collapsible screen means attached between sash and frame and adapted to enclose, when in the open position, that space between sash and frame and to nest closed in a collapsed state when sash and frame are in the closed position.
Particularly, the collapsible screen means is structured as a bellow from sheet plastic material which is either translucent or clear and preferably from a durable plastic sheet, for instance, that of Mylar~. The collapsible screen means is structured as bellows which is affixed to the inner portion of the sash, on the one hand, and the window sash or frame, on the other hand, so that when the sash is in its pivotable open position collapsible screen means occupy the peripheral margin about and between the same so as to provide screening. There are a plurality of apertures in the plastic sheet material so as to provide air flow therethrough.
The invention will now be described by way of example and reference to the accompanying drawings in which:
Figure 1 is a side perspective view with the window opening along its sash side element;
Figure 2 is a section along lines II-II of Figure 1, the section being through a wooden sash; the bottom sectional 212~60~
view being identical thereto;
Figures 3 is a side, partial section view of my novel window wherein the sash is extruded and the accordion-like screen is integral therewith;
Figure 4 is a bottom section view of my novel accordion-like screen as a retrofit in an existing two-pane extruded sash.
Referring to Figure 1, a window sash frame (S) comprises an upper element (10) and left and right side elements (11) and (13) together with a lower element (12).
The upper element (11) is formed from a single section of suitable material and the side and lower elements (11, 12, and 13) of the same material. The material in Figure 2 is shown as wood while in Figures 1, 3 and 4, is extruded aluminum. The left side element (11) is also the hinge side element while the right side element (13) is also the open side element.
The sash (15) is hingeably mounted (not clearly shown), in the normal fashion along the hinge side (11) so that it pivots open. It holds a window pane (16) with double glass (16',16").
Along the inner peripheral margin (17) is an accordion-like screen (20) with gussets (21) creating a plurality of bellows (22) which are shown relatively open in Figures 1 and 2, and closed in Figures 3 and 4. Each gusset (210) defines apertures, not clearly shown, so as to construct the accordion-like screen. Preferably, the material from which the accordion-like screen is constructed is a flexible force plastic sheet, translucent or clear, shaped as an accordion, and defining a plurality of small apertures in each gusset so as to provide screening characteristics when in the open position.
In the retrofit cross-sectional Figure 4, the accordion-like screen (21') is shown collapsed and is within a U-shaped cross-sectional housing (30). The outermost gusset, noted as (24) in Figures 2, 3 and 4 is adhesively affixed to (or attached by other suitable means) to a piece of square, in cross section, stock (35) that has an -appropriate adhesive along the side, referenced (36) in Figure 4. The housing (30) has a single adhesive surface (37) on one of its distal arms. Together, these elements are referenced (50).
Referring to Figure 4, when the window opens, the square-in-section element (35) moves with the window (15) to provide screening, as shown in Figures 1 and 2.
Referring to Figure 3, the sash (S) is constructed so that my novel screen (20) is built into the internal peripheral surround of the sash, as shown. As such, the bellows (22) nest within a U-shaped member (30) wherein at least three sides, preferably four, thereof can be affixed to the internal portions of the extruded sash by convenient means such as welding, riveting, gluing or the like. The outermost gusset (24) terminates on a base strip (25) which is appropriately adhered to or affixed to the internal margin (17) of the window (15), along at least three sides and preferably four. In these Figures 4 and 5, (30) is a crank which causes the window to open by turning the same and operating the internal mechanism, shown as (35) within the window sash. In the cross-section, Figure 2, there is a lock (36) which is integral to the crank so as to lock the window closed.
This invention relates to window structures, and in particular, to window structures having built-in fly screens.
It is now common in building construction, especially housing construction, to use prefabricated windows that are secured in place in rough framing, usually prior to application of sheathing on the exterior of the building, and of gypsum board covering on the inside of the building. For convenience, including locks, hinges and fly screens, and often mechanical means for opening and closing the window, such as a crank and linkage.
In warm climates, the fly screen associated with such units is necessary to prevent the entry of undesired insects such as mosquitoes. Indeed, in some climates, the absence of a fly screen would make comfortable occupancy of the building almost impossible.

The disadvantage with this type of window structure is that the fly screen-is rigid and therefore, the depth of the frame and sash must be sufficient to encapsulate the screen when put into the closed position. This is most clearly seen in Figure 3 and Figure 1 of the aforesaid patent. The width or depth of the sash therefore, has to be increased in order to accommodate such fly screen and this adds to costs and is not as pleasing to the eye, when the window is viewed from the outside since the window sash or frame protrudes outwardly from the wall.
It is an ob~ect of the invention to overcome this problem; to reduce the depth of the sash, and yet to provide a collapsible fly screen which, when in the closed position, is essentially non-viewable, while in the open position to provide screening from insects and the passage of airflow through the screen, and always maintaining a clear view through the glass without the impediment of ever having an overcoverlng screen.

The invention therefore contemplates a window unit comprising a window sash frame, a sash hingeably mounted to said sash frame for pivotal movement between a closed position juxtaposed with the sash frame, and an open position in which a space is defined between the sash frame and sash and, a collapsible screen means attached between sash and frame and adapted to enclose, when in the open position, that space between sash and frame and to nest closed in a collapsed state when sash and frame are in the closed position.
Particularly, the collapsible screen means is structured as a bellow from sheet plastic material which is either translucent or clear and preferably from a durable plastic sheet, for instance, that of Mylar~. The collapsible screen means is structured as bellows which is affixed to the inner portion of the sash, on the one hand, and the window sash or frame, on the other hand, so that when the sash is in its pivotable open position collapsible screen means occupy the peripheral margin about and between the same so as to provide screening. There are a plurality of apertures in the plastic sheet material so as to provide air flow therethrough.
The invention will now be described by way of example and reference to the accompanying drawings in which:
Figure 1 is a side perspective view with the window opening along its sash side element;
Figure 2 is a section along lines II-II of Figure 1, the section being through a wooden sash; the bottom sectional 212~60~
view being identical thereto;
Figures 3 is a side, partial section view of my novel window wherein the sash is extruded and the accordion-like screen is integral therewith;
Figure 4 is a bottom section view of my novel accordion-like screen as a retrofit in an existing two-pane extruded sash.
Referring to Figure 1, a window sash frame (S) comprises an upper element (10) and left and right side elements (11) and (13) together with a lower element (12).
The upper element (11) is formed from a single section of suitable material and the side and lower elements (11, 12, and 13) of the same material. The material in Figure 2 is shown as wood while in Figures 1, 3 and 4, is extruded aluminum. The left side element (11) is also the hinge side element while the right side element (13) is also the open side element.
The sash (15) is hingeably mounted (not clearly shown), in the normal fashion along the hinge side (11) so that it pivots open. It holds a window pane (16) with double glass (16',16").
Along the inner peripheral margin (17) is an accordion-like screen (20) with gussets (21) creating a plurality of bellows (22) which are shown relatively open in Figures 1 and 2, and closed in Figures 3 and 4. Each gusset (210) defines apertures, not clearly shown, so as to construct the accordion-like screen. Preferably, the material from which the accordion-like screen is constructed is a flexible force plastic sheet, translucent or clear, shaped as an accordion, and defining a plurality of small apertures in each gusset so as to provide screening characteristics when in the open position.
In the retrofit cross-sectional Figure 4, the accordion-like screen (21') is shown collapsed and is within a U-shaped cross-sectional housing (30). The outermost gusset, noted as (24) in Figures 2, 3 and 4 is adhesively affixed to (or attached by other suitable means) to a piece of square, in cross section, stock (35) that has an -appropriate adhesive along the side, referenced (36) in Figure 4. The housing (30) has a single adhesive surface (37) on one of its distal arms. Together, these elements are referenced (50).
Referring to Figure 4, when the window opens, the square-in-section element (35) moves with the window (15) to provide screening, as shown in Figures 1 and 2.
Referring to Figure 3, the sash (S) is constructed so that my novel screen (20) is built into the internal peripheral surround of the sash, as shown. As such, the bellows (22) nest within a U-shaped member (30) wherein at least three sides, preferably four, thereof can be affixed to the internal portions of the extruded sash by convenient means such as welding, riveting, gluing or the like. The outermost gusset (24) terminates on a base strip (25) which is appropriately adhered to or affixed to the internal margin (17) of the window (15), along at least three sides and preferably four. In these Figures 4 and 5, (30) is a crank which causes the window to open by turning the same and operating the internal mechanism, shown as (35) within the window sash. In the cross-section, Figure 2, there is a lock (36) which is integral to the crank so as to lock the window closed.
