Abstract
A method for assembling a window is described including forming a lineal member having a cross-sectional profile, where the profile includes a sash portion and a frame portion, cutting the lineal member into lengths sized for forming the window, and joining the lengths of the lineal member to form a shape of the window. The sash portions form a sash and the frame portions form a frame. Then the sash is separated from the frame.
Description




FIELD OF THE INVENTION




The present invention is directed to a method for constructing a window and more particularly to a efficient method for constructing a window by combining the manufacture and/or assembly of certain window components.




BACKGROUND OF THE INVENTION




A typical window includes at least a frame and a sash. The frame is mounted into a wall or other structural component, and forms the outer perimeter of the window. The sash fits within the frame, and holds the glazing, such as glass. The frame and sash are frequently each composed of four separate linear members that are joined at the corners to form a rectangle. Often the linear members are initially hollow. For venting windows, at least a portion of the sash is movable with respect to the frame. For non-venting or stationary windows, the sash will not be movable.




During manufacturing, a single length of a sash profile, for example, may be manufactured at once, and then cut into the individual linear sash members to form the sash. Extrusion methods may be used to form the single lengths. Then the individual linear sash members are joined to form the rectangular shape of the sash. A similar process may be used to form the frame.




If two separate components, such as a frame and a sash, are used in a window, then two separate lengths of profile must be produced and two separate cutting and assembly processes must be undertaken to make the individual components of the window. For a typical window including a sash and a frame with a perimeter of about 14 feet, the conventional approach requires about 28 feet of various linear components in order to form one window. In addition, each sash linear component and each frame linear component require several additional assembly steps in order to form a window. For example, mitered corners must be formed on each linear component of the sash and the frame. Also, the sash lineal components and the frame lineal components are separately assembled into the sash and the frame, respectively. Because the sash and the frame are assembled separately, it is possible for some discrepancies to exist between the shape of the sash and the shape of the frame so that the two components may not fit perfectly together. A substantial need exists for a less expensive, more efficient, and higher quality method of producing a window, especially using linear members.




SUMMARY OF THE INVENTION




Generally, the present invention provides efficiencies and quality improvements in methods for manufacturing windows by combining the formation of certain components, such as a sash and a frame, and by combining assembly steps. In one particular embodiment of the invention, a method for assembling a window includes the steps of forming a lineal member having a cross-sectional profile, where the profile includes a sash portion and a frame portion. The method includes separating the lineal member into a plurality of lengths, joining the lengths to form a shape of the window, where the sash portions form a sash and the frame portions form a frame, and separating the sash from the frame.




In one embodiment of the invention, the method may include the step of installing hardware onto the frame and sash, such as a lock, an operator, and/or a hinge. In a preferred embodiment, the sash portion includes an extension portion that at least partially conceals a platform of the frame where the actuator is attached to the frame when the sash and frame are in a closed position.




In another particular embodiment of the invention, a cover portion may be included in the profile of the lineal member. The cover may be capable of enclosing hardware that is installed on the frame. In another particular embodiment, the cover portion includes a hinge portion and the method may include the steps of bending the cover portion at the hinge portion, installing hardware on the frame portion and securing the cover portion to the frame portion.




The present invention also includes a method for manufacturing windows whereby a single production operation is used to form both venting windows and non-venting windows until a final step of separating a sash from a frame for venting windows. First, a lineal member is formed having a cross-sectional profile, the profile including a sash portion and a frame portion. The method further includes cutting the lineal member into lengths sized for forming a window, joining at least four of the lengths of the lineal member to form a shape of a window, where the sash portions form a sash and the frame portions form a frame. The method further includes separating the sash from the frame where a venting window is desired and allowing the sash and frame to remain connected for a non-venting window.

DETAILED DESCRIPTION OF THE VARIOUS EMBODIMENTS




The present invention is believed to be applicable to a variety of methods and systems for constructing windows and other structural components. The invention has been found to be particularly advantageous in application environments where production of more than one linear component can be combined. While the present invention is not so limited, an appreciation of various aspects of the invention is best gained through a discussion of various application examples operating in such an environment.





FIG. 1

is an example of a window


18


that can be produced using the method of the present invention. An out-swinging casement window


18


is illustrated, including a frame


20


, a sash


22


, and glazing


24


. The frame


20


is made of four individual frame members


25


, while the sash


22


is made of four individual sash members


26


. The window


18


may include some hardware components, such as an operator


28


, for opening and closing the window, and a latch


29


.




Although many other shapes are possible, and can be constructed using the method of the present invention, rectangles are the most common shape for windows and only rectangles will be discussed in connection with the Figures. However, the invention can be applied to windows of many shapes other than rectangles.




The present invention is particularly useful for forming hinged venting windows in combination with non-venting or stationary windows, as will be discussed further below. In the drawings, only out-swinging casement windows are illustrated, however, the manufacturing steps of the present invention are applicable to many different types of windows or doors, such as in-swinging casement windows. For example, the present invention would be very useful for manufacturing all types of hinged windows and doors, including casement windows, basement windows, and awning windows. The present invention could be utilized for these and other types of doors and windows that swing either toward the indoors or toward the outdoors. In addition, the manufacturing steps of the present invention are also applicable to non-hinging windows or doors, such as sliding windows or doors or double hung windows.




According to the invention, two or more components of the window can be formed in the same manufacturing process and later be separated. A lineal member is formed that includes a frame portion and a sash portion. A lineal member is a linear component of a window that generally has a uniform cross-section along its length. In one embodiment, the linear member is then cut into lengths sized for forming a window. The lengths are joined to form the shape of a window, where the sash portions form a sash and the frame portions form a frame. Then the sash may be separated from the frame to form a venting window. Other window components, such as a cover or cladding or trim attachment portions may also be included in the profile of the lineal member, and will be discussed in more detail below.




One advantage of the present invention is production efficiency because the lineal member is formed in one process but includes both the sash portions and the frame portions. Efficiencies are also achieved during assembly. For example, mitered corners can be cut on both the sash members and frame members simultaneously when they are both part of the lineal member. Also, the step of joining the mitered corners of the lineal members together provide the sash and frame comer connections in one step. Another advantage of the present invention is that venting and non-venting windows may be constructed using many of the same production steps, up until the time when the sash and frame are separated. As a result, the manufacturing equipment needed to make both window styles is reduced. For example, casement windows and stationary windows are often made in the same assembly plant because these two types of windows are desirable for combinations in one location in a home. According to the present invention, casement windows and stationary windows may be manufactured using a single production assembly line up until the step of separating the sash from the frame for the venting windows.




Another advantage of the present invention is the increased likelihood of establishing a perfect fit between a sash and a frame formed using the present invention. Because the sash and frame are still connected in the lineal profile when the lineal members are joined at the corners to form a window, the sash and frame will have an identical shape, even if this shape is a slightly imperfect rectangle.




In one preferred embodiment of the invention, a lineal member


30


shown in cross-section in

FIG. 6

, is formed including both a frame portion


34


and a sash portion


36


. The process of manufacturing a window according to the present invention will now be discussed with reference to

FIGS. 2-5

which show manufacturing assembly steps.




The profile of the lineal member


30


that is illustrated in

FIGS. 6 and 7

will be discussed in relation to the assembly method of

FIGS. 2-5

. However, it should be understood that other profile configurations are possible and are contemplated for use with the manufacturing steps of the present invention. Other examples of profile configurations will be specifically discussed with reference to

FIGS. 8-12

. The profiles of

FIGS. 8-12

may be incorporated into a window manufacturing process using many of the same manufacturing steps as are illustrated and will be discussed with reference to

FIGS. 2-5

.




First, a lineal member


30


is formed having a uniform cross-section (as shown in

FIG. 6

) along its length. The lineal member


30


includes a frame portion


34


and a sash portion


36


. After formation, the lineal member


30


is then cut into smaller, individual lengths


38


for making a window, as shown in FIG.


2


. Each length


38


includes a frame member


25


and a sash member


26


that are joined together. The individual lengths


38


are provided with appropriate comer angles


40


for joining into the desired window shape. For example, the lengths


38


can be provided with mitered corners for forming a rectangle.




Then, ends of the individual lengths


38


are joined together to form a window shape outline


41


, as shown in FIG.


3


. Adhesive, corner keys, welding or other joining techniques known in the art are used to join the unitary members into the window shape.




The glazing panel


24


may be installed in the sash


22


by a variety of methods known in the art, including bed glaze construction or groove glaze construction. As shown in

FIG. 4

, a panel of glazing panel


24


is preferably installed by placing it on a ledge


42


that is a part of the sash portion


36


of the lineal members


30


. The ledge


42


is also illustrated in FIG.


6


. Preferably, an adhesive and/or sealant is applied to the ledge


42


before the glazing panel


24


is dropped into place. This type of construction is commonly referred to as bed glaze construction.




Then a trim strip, such as a glazing bead or a cladding profile, may be added to the edge of the glazing panel


24


, opposite the ledge


42


, as is known in the art. A glazing bead is typically applied in separate lengths around the perimeter of the glazing. A cladding can be either applied one length at a time, or can be formed into a rectangle and snapped into place over the glazing.




An alternative method of installing the panel of glazing is to assemble the window outline


41


around the panel of glazing


24


. Although this method is not illustrated, it will be understood by those of skill in the art that the individual lengths


38


may be joined to form the window shape


41


, as shown in

FIG. 2

, around the panel of glazing, where an adhesive or sealant is placed on the area of the individual lengths


38


that will be in contact with the panel of glazing. This type of construction is commonly referred to as groove glaze construction. In groove glaze construction, the sash portion may differ from the sash portion illustrated in

FIG. 6

because the sash portion may include a groove for holding the glazing panel.




During groove glaze construction adhesive may be pushed aside by the edge of the glazing panel


24


as the individual lengths


38


are assembled to form the window shape


4




1


, resulting in a less reliable seal between the glazing panel and the sash. As a result, bed glaze construction is the preferred method for installing a panel of glazing in the present invention.




A complete stationary window is now formed. Where a venting window is desired, the next step in the process of assembling a window according to one embodiment of the present invention is to separate the sash from the frame in the window


18


. As shown in

FIG. 5

, the material joining the sash portion


36


to the frame portion


34


is cut, using routers


43


for example. In

FIG. 6

, two webs of material


44


and


45


that join the frame portion


34


and the sash portion


36


are illustrated near routers


43


. After the webs of material


44


and


45


are cut, the frame portion and the sash portion are separate components. Now, hinges, locks, openers, and other hardware components can be installed to the sash or frame or to the intersection between the sash and the frame in order to create an operating window, as shown in FIG.


1


.




According to the present invention, the two production processes for forming the frame and sash components are replaced by one production process for forming the lineal member


30


. Using the preferred embodiment, two separate assembly processes for forming the frame


20


and sash


22


from individual lengths are replaced by one assembly process. Because the frame


20


and sash


22


are assembled while the sash portion


36


and frame portion


34


are still joined together in the lineal member, a proper fit between the frame


20


and sash


22


is more likely than if the sash and frame were separately assembled. As a result, manufacturing efficiency and accuracy are improved.




Where a stationary window is desired rather than a venting window


18


, the connection between the sash and the frame remains intact. A stationary window made by this procedure has the advantage of having an intact physical connection between the sash and the frame to improve the weathertightness and sturdiness of the stationary window. In some current methods for producing stationary windows, separate sash and frame components are extruded and formed into a sash and a frame, respectively, and then the sash and frame are fastened together with clips or otherwise joined together to form a stationary window. However, by forming a stationary window according to the present invention, there is no need for clips or for an additional joining step. In addition, a stationary window can be formed using many of the same assembly steps that are used to form a venting window, so that similar production equipment and a nearly identical assembly line may be utilized for forming stationary windows according to the present invention.




In a less preferred second alternative embodiment of the present invention, the lineal member


30


is divided into the sash members


26


and frame members


25


before the members are joined to form the sash


22


and frame


20


, respectively. Now referring to

FIG. 2

, the frame member


25


and the sash member


26


may be separated from each other before the rectangles of the frame and sash that will form the window are joined together at the corners. The frame member


25


and the sash member


26


may or may not be separated from each other before the mitered corners are applied. Then, a completely formed sash and a completely formed separate frame would result, rather than the combined sash and frame formed in FIG.


3


. The next step would be installing a panel of glazing, similar to the step shown in

FIG. 4

, except that the panel glazing would be installed in the sash alone. The step of separating the sash and frame shown in

FIG. 5

for the preferred embodiment would not be necessary in this alternative embodiment, because the sash and frame would already be separated. This alternative embodiment would not take advantage of many of the assembly efficiencies of the preferred embodiment, but would eliminate the need for two separately extruded sash and frame profiles.




Now referring to

FIG. 6

, one embodiment of the profile


30


of the lineal member


38


will be discussed in greater detail. The sash portion


36


will be separated from the frame portion


34


by cutting two webs of material


44


and


45


. Each of the webs


44


and


45


may instead include two or more webs, so that a total of four or more webs would be cut to separate the sash from the frame. Many other connecting web configurations are possible, and some additional examples will be discussed herein. The sash portion


36


includes a ledge


42


for supporting the glazing panel


24


.

FIG. 6

also illustrates an interior stop or glazing bead


46


that is attached using a screw to the sash portion


36


. The glazing bead provides a finished trim to the edge of one side of the glazing opposite from the ledge


42


. More commonly, a glazing bead is attached to the sash using a snap-fit or friction-fit configuration, rather than a visible screw. Any of these attachment techniques, and other techniques that are known in the art, may be used in connection with the present invention.




A spacing device


47


is also illustrated in

FIG. 6

between two pieces of glass that form the insulated glazing panel


24


. The profile


30


also includes a platform


53


for attachment of an operator to open and close the window, as will be discussed in more detail below. A weather stripping groove


54


may be provided in the frame portion


34


to allow attachment of a weather stripping bulb.





FIG. 7

shows a cross-sectional view of the lineal member


30


, with the sash portion


36


and the frame portion


34


separated and hardware installed. An operator


48


is attached to the platform


53


of the frame portion


34


, including an operator arm


49


that is attached to a surface of the sash portion


36


, and a handle


50


. A hinge


52


is connected to both the sash portion


36


and the frame portion


34


. In addition, a weather stripping bulb


51


is situated in between the sash portion and the frame portion to provide for a weather tight seal between the sash and the frame, held in the weather stripping groove


54


.





FIGS. 8 and 9

illustrate an alternative design of a lineal member profile


80


of the present invention. The lineal member profile


80


includes a frame portion


82


and a sash portion


84


. In this embodiment of the lineal member


80


, one web of material


81


connects the frame portion


82


to the sash portion


84


. The profile


80


also includes a ledge


86


for supporting a panel of glazing. A platform


88


is included in the frame portion


82


for attachment of an operator for opening and closing the window. The profile also includes an exterior surface


87


that will face the exterior of the structure when the window is installed in a structure. In addition, a groove


89


for supporting a weather stripping bulb and a groove


83


for attaching a glazing bead are shown in FIG.


8


. The profile


80


also includes two cover attachment portions


85


that may be used to attach a cover to the frame portion


82


.




In

FIG. 9

, the profile


80


is shown in cross-section in an assembled position. A panel of glazing


90


has been installed on the ledge


86


. A glazing bead


91


is also included, fitting into the groove


83


. An operator


92


is attached to the platform


88


of the frame portion


82


, including an operator arm


93


attached to the sash portion


84


and a handle


95


. A hinge


94


is also included. A weather stripping bulb


96


is provided between the sash portion


84


and the frame portion


82


to improve the weathertightness of the window. A cover


97


is shown in place over a portion of the operator


92


, attached to the cover attachment portions on the frame portion


82


. The use of a cover


97


may provide the consumer with distinct aesthetic features on the interior frame portion, and may hide the operator mechanisms, providing for a more attractive interior appearance. Preferably, the cover


97


is formed in a separate process from the rest of the profile


80


. The embodiment shown in

FIGS. 8 and 9

has the advantage of only one connecting web of material, and provides interior cover options.




Now referring to

FIGS. 10 and 11

, a third embodiment of a profile


100


of the present invention is illustrated in an unassembled state in FIG.


10


and in an assembled state in FIG.


11


. The profile


100


includes a frame portion


102


and a sash portion


103


that are connected by one web of material. A cut along line A—A will separate the sash portion from the frame portion. The profile


100


includes a ledge


104


to support a glazing panel


105


. The frame portion


102


includes cover attachment portions


106


for attaching to a cover


107


. The sash portion


103


includes cladding attachment portions


108


for attaching to a cladding


109


. The cover


107


fits over the interior portion of the frame portion


102


, may provide a different aesthetic appearance to the interior of the window and may also disguise hardware such as an operator for opening and closing the window. The cladding


109


fits onto the exterior portion of the sash portion and the frame portion to provide an aesthetic appearance to the exterior of the window. In addition, the cladding portion may provide a finished trim to one side of the glazing panel


105


. The cladding


109


and cover


107


will preferably be made in separate production processes from the rest of the profile


100


, and may therefore be provided with color for design purposes.




One advantage of the cover attachment and cladding attachment options illustrated in

FIGS. 10-11

is that an underlying window chassis can be mass produced, but color and design variations can be made by attaching cover and cladding portions having different design features, shapes, and colors. Windows with many different colors and shapes can be produced using largely the same assembly line and largely the same inventory of components, since only the cladding and/or cover portions need to be varied.




The frame portion


102


further includes a T-groove


10


that can be attached to a nailing flange for attaching the frame to a building. A weather stripping portion


111


may be provided between the sash and the frame and may fit into a weather stripping groove


112


on the frame portion


102


. An operator


113


may also be installed on a platform


115


of the frame portion


102


, including a handle


116


. Although an operator bar is not illustrated in

FIG. 1

, such an operator bar may be provided with the embodiment of

FIGS. 10 and 11

in a manner similar to that illustrated in

FIG. 9

, making a connection between the operator


113


and the sash portion


103


. Likewise, although a hinge is not illustrated in

FIG. 11

, a hinge could be provided similar to the hinge illustrated in FIG.


9


.




An alternative embodiment lineal member


120


of the invention is shown in FIG.


12


. This lineal member


120


includes a frame portion


121


, a sash portion


122


, and a cover portion


123


. A cover portion


123


can be included on the interior surface of a window frame of the present invention, and can hide hardware such as an operator for opening the window or provide a unique aesthetic appearance, but is not required. The cover


123


may include a hinge portion


124


, made of a more flexible material than the remainder of the cover


123


. The hinge portion


124


allows the cover


123


to be bent back to expose the frame portion underneath, after the cover


123


has been separated from the frame at the non-hinging edge of the cover. A cut along line B—B in

FIG. 12

may be used to separate the non-hinging side of the cover


123


from the frame


121


. This arrangement allows hardware components to be installed on the frame member and then be concealed under the cover


123


, after the window is assembled. After a sash and frame of a window is assembled, hardware such as an operator, window locks, and other devices are typically installed. Then the cover is bent back into place and secured using methods known in the art so that the cover is covering the hardware. If the cover


123


is not provided with a hinge area, the cover can be removed with a cut to allow hardware installation and then be reattached using methods known in the art.




Preferably, the lineal member


120


of

FIG. 12

is made of a vinyl material formed by extrusion while the hinge portion


124


is a softer, plasticized vinyl that is co-extruded with the remainder of the lineal member


120


, as is known in the art. The sash portion


122


shown in

FIG. 12

includes a ledge


125


for supporting a glazing panel. The sash portion


122


may also include an attachment device


126


for receiving a cladding portion. The frame portion


121


may include a groove


127


for receiving a T-shaped nailing or stapling flange that can be secured to the structure or wall into which the window is being installed. The lineal member


120


can be assembled into a window using the methods discussed above. The lineal member


120


is cut near line B—B to separate the frame portion


121


from the sash portion


122


. In this embodiment, two webs of material are cut to separate the frame from the sash, and to separate the cover from the sash along line B—B.




The lineal profiles shown in

FIGS. 6-12

incorporate different features, such as T-shaped grooves for receiving nailing flanges, attachment points for cladding profiles, and glazing beads of different configurations. Those of skill in the art will understand that many of these various features, although they may be illustrated on only one of the Figures, may be included in any of the lineal profile designs that were discussed. For example, a T-shaped groove for receiving a nailing flange could be provided on the profile


30


shown in

FIGS. 6 and 7

or on the profile


80


shown in

FIGS. 8 and 9

, although it is not illustrated in those drawings.




Details of producing a lineal member of the present invention will now be discussed. The lineal member may be produced using a variety of methods that are known in the art. The most preferred method is extrusion using vinyl, such as polyvinyl chloride (PVC), or a wood polymer composite. The lineal members of the invention could be formed with a color layer on exterior surfaces of the lineal member by co-extrusion with a colored material. However, injection molding methods, roll-formed metal methods, wood milling methods and other methods may also be used, where a length of the profile may be formed with a consistent cross-section. Where injection molding is used, materials such as ABS (Acrylonitrile Butadiene Styrene), polyethylene, polycarbonate, polypropylene or another polymer could be used. For injection molding, the sash and frame portions could be initially joined by points of connection, a continuous connection web, or an intermittent connection pattern. The lineal member could also be made of metal, aluminum, wood, and a variety of other materials that can be used to form a length of a profile with a consistent cross-section that is capable of being separated into a sash profile and a frame profile. For example, the lineal member could be formed by roll-forming metal, by pultrusion of fiberglass, or by wood milling.




Although many materials can be used with the present invention, the use of vinyl or a wood and polymer composite in an extrusion process is probably the most feasible and practical method of practicing the invention. A preferred wood and polymer composite material is described in U.S. Pat. No. 5,406,768, which is incorporated herein by reference in its entirety. Durability, insulation qualities, and cost are important factors to consider when choosing a material for a window. Extrusion design tolerances should also be considered when choosing a material and when designing a profile configuration. Design tolerances can vary widely depending on the dimensions of the profile, the material used, and many other factors.
