Definitions
- This invention relates generally to muntin grids for sash window assemblies and more specifically to a muntin clip for positioning the grid within a sash window.
- Double hung window assemblies typically include a pair of sash windows slidably mounted within a master frame.
- sash windows were provided with a grid of muntin bars, typically made of wood, that separated and held multiple panes of glass within a sash. Each pane would be mounted within the sash in the same plane.
- double or multiple pane windows are provided, otherwise known as insulated or thermo-pane window assemblies.
- These insulated window assemblies include a pair of glass panes mounted in parallel relation to one another within a sash frame and separated by a small distance. The panes are typically separated by a spacer frame located about a periphery of the panes.
- insulated or thermo pane windows are not limited to single or double hung window arrangements. Rather, they have a wide range of applications that are well known in the art. For instance, double pane windows may be incorporated in doors, picture windows, etc.
- Grids formed by interconnected muntin bars are often installed between these glass panes of a double pane or insulated sash window.
- these grids are comprised of multiple muntin bars arranged in a grid pattern and interconnected at interior intersecting points by muntin joiners.
- the grid is then placed between the panes of glass.
- the periphery of the grid is then mounted to the sash frame, or more typically, to a spacer frame separating the panes, by a series of muntin clips. It is understood that the grid can take a variety of different forms.
- the muntin bars are of a tubular or hollow construction and a portion of the clip is received by an end of a muntin bar located at a periphery of the grid.
- the hollow muntin bar receives an extension or bar support of the clip that is designed to fit tightly within the hollow muntin bar to effect an interference fit, thereby attaching the muntin clip to the muntin bar end. (See FIG. 3 )
- the clip in turn is attached or connected in some way to the spacer frame.
- An example of a prior art muntin clip is shown in cross section in FIG. 3 .
- the prior art muntin clip 1 includes a bar support 2 , in the form of a tree, tightly fitting within and received by a muntin bar 3 .
- Muntin grids including the bars, joiners and clips of which they are comprised, come in numerous shapes and sizes.
- One drawback resulting from this fact is that muntin clip manufactures must design and produce a separate clip to match each potential size/shape of muntin bar available on the market and to also match with a variety of sizes of spacer frames.
- a conservative estimate is that there are currently at least 500 muntin clip designs available on the market to accommodate the multitude of sizes and shapes that can be found in the available muntin bars. This costs clip manufacturers, and window manufacturers or assemblers to incur costs associated with maintaining and otherwise dealing with large and varied inventories of muntin clips.
- FIGS. 4-5 show a spacer frame.
- the spacer frame typically has a lateral wall having a length C, a pair of vertical walls having a height B, and a pair of shoulders, each having a length X.
- the shoulders are separated by a distance A.
- various window designs may and do require variously sized spacer frames.
- a manufacturer will adjust the length of the lateral wall C to accommodate window designs having differing widths between their multiple panes of glass.
- the height B of the vertical wall and the length of the shoulder X remain as constants. Therefore, as the length C of the lateral wall varies between the various required spacer frame designs, the distance A between the shoulders also varies. This distance plays a role in determining what muntin clip may be used with a particular spacer frame.
- muntin clip there are at least two factors dictating what type or design of muntin clip may be used in a particular window assembly.
- First is the configuration of the muntin bar to be used.
- the second factor is the configuration of the spacer frame.
- the multitude of variations available in both muntin bars and spacer frames results in the present existence of at least 500 different muntin clip designs currently being available. This in turn causes clip manufacturers and window assemblers to be burdened with large clip inventories.
- certain muntin clip designs require complex molds in the manufacturing process.
- the present invention provides a muntin clip having an overall flexible support structure that allows the clip to be connected to a plurality of muntin bars and spacer frames having a variety of sizes.
- the muntin clip includes a base member adapted for connection to the spacer frame and a bar support adapted for connection to the muntin bar end.
- the base member has a first segment, a second segment, and a mount structure.
- the bar support extends from the base member and has a first segment extending from the first segment of the base member and a second segment extending from the second segment of the base member.
- the bar support contains flexible bow members that are deformable to allow for connection to a variety of different muntin bars.
- a flexible hinge member connects the first segment of the bar support to the second segment of the bar support, allowing the muntin clip assembly to move between an unfolded position and a folded position.
- a tension mechanism exerts outward force on the first and second segments of the base member when the muntin clip assembly is in the folded position, allowing for enhanced connection to a spacer frame and also for connection to a variety of different spacer frames.
- the tension mechanism includes a resilient spring member and an abutment member located on the base member.

- the unfolding force of the hinge member 108 combines with the outward force F exerted by the tension mechanism 120 to push the base segments 102 a, 102 b apart, allowing the base 102 to connect to a variety of different spacer frames, as described above.

The bar support segments are inserted into a muntin bar end and the base segments are inserted into the spacer frame.

Nos. 11/186,387 and 11/298,304, which Applications are incorporated by reference herein and made a part hereof. These structures could be slightly modified and incorporated with the flexible member 108 as discussed above to provide a muntin clip having an unfolded position and a folded position.
- the flexible components of the bar support of the muntin clip described above permit a single clip to be connected to any of a variety of different muntin bars having a variety of different dimensions and configurations.
- the flexible mount structure and tension mechanism of the base permits a single clip to be connected to any of a variety of different spacer frames having a variety of different dimensions and configurations, and having openings of a variety of different widths.
- the clip can be manufactured in the unfolded position, which reduces the complexity of the mold.
- the mold can be a more simple, straight open/close tool. Accordingly, the need for sliding motion of mold parts is eliminated. These features extend the life of the tool through increased strength and less unexpected or incidental damage to the tool. In addition, because of the reduced complexity, the cycle time associated with forming the muntin clip is reduced.

Abstract
A muntin clip is adapted to be connected to a muntin bar end and a spacer frame. The muntin clip includes a base member adapted for connection to the spacer frame and a bar support adapted for connection to the muntin bar end. The base member has a first segment, a second segment, and a mount structure. The bar support extends from the base member and has a first segment extending from the first segment of the base member and a second segment extending from the second segment of the base member. A flexible hinge member connects the first segment of the bar support to the second segment of the bar support, allowing the muntin clip assembly to move between an unfolded position and a folded position. A tension mechanism exerts outward force on the first and second segments of the base member when the muntin clip assembly is in the folded position.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/757,116, filed Jan. 6, 2006, which is expressly incorporated herein by reference and made a part hereof.
- This invention relates generally to muntin grids for sash window assemblies and more specifically to a muntin clip for positioning the grid within a sash window.
- Double hung window assemblies typically include a pair of sash windows slidably mounted within a master frame. In the past, sash windows were provided with a grid of muntin bars, typically made of wood, that separated and held multiple panes of glass within a sash. Each pane would be mounted within the sash in the same plane. Now, double or multiple pane windows are provided, otherwise known as insulated or thermo-pane window assemblies. These insulated window assemblies include a pair of glass panes mounted in parallel relation to one another within a sash frame and separated by a small distance. The panes are typically separated by a spacer frame located about a periphery of the panes. Of course, insulated or thermo pane windows are not limited to single or double hung window arrangements. Rather, they have a wide range of applications that are well known in the art. For instance, double pane windows may be incorporated in doors, picture windows, etc.
- Grids formed by interconnected muntin bars are often installed between these glass panes of a double pane or insulated sash window. Typically, these grids are comprised of multiple muntin bars arranged in a grid pattern and interconnected at interior intersecting points by muntin joiners. The grid is then placed between the panes of glass. The periphery of the grid is then mounted to the sash frame, or more typically, to a spacer frame separating the panes, by a series of muntin clips. It is understood that the grid can take a variety of different forms.
- Typically, the muntin bars are of a tubular or hollow construction and a portion of the clip is received by an end of a muntin bar located at a periphery of the grid. Typically, the hollow muntin bar receives an extension or bar support of the clip that is designed to fit tightly within the hollow muntin bar to effect an interference fit, thereby attaching the muntin clip to the muntin bar end. (See
FIG. 3 ) The clip in turn is attached or connected in some way to the spacer frame. An example of a prior art muntin clip is shown in cross section inFIG. 3 . The prior art muntin clip 1 includes abar support 2, in the form of a tree, tightly fitting within and received by a muntin bar 3. - Muntin grids, including the bars, joiners and clips of which they are comprised, come in numerous shapes and sizes. One drawback resulting from this fact is that muntin clip manufactures must design and produce a separate clip to match each potential size/shape of muntin bar available on the market and to also match with a variety of sizes of spacer frames. A conservative estimate is that there are currently at least 500 muntin clip designs available on the market to accommodate the multitude of sizes and shapes that can be found in the available muntin bars. This costs clip manufacturers, and window manufacturers or assemblers to incur costs associated with maintaining and otherwise dealing with large and varied inventories of muntin clips.
-
FIGS. 4-5 show a spacer frame. The spacer frame typically has a lateral wall having a length C, a pair of vertical walls having a height B, and a pair of shoulders, each having a length X. The shoulders are separated by a distance A. As one might expect, various window designs may and do require variously sized spacer frames. Typically, a manufacturer will adjust the length of the lateral wall C to accommodate window designs having differing widths between their multiple panes of glass. However, for each different value of C (length of lateral or bottom wall), the height B of the vertical wall and the length of the shoulder X remain as constants. Therefore, as the length C of the lateral wall varies between the various required spacer frame designs, the distance A between the shoulders also varies. This distance plays a role in determining what muntin clip may be used with a particular spacer frame. - Accordingly it can be seen that there are at least two factors dictating what type or design of muntin clip may be used in a particular window assembly. First is the configuration of the muntin bar to be used. The second factor is the configuration of the spacer frame. The multitude of variations available in both muntin bars and spacer frames results in the present existence of at least 500 different muntin clip designs currently being available. This in turn causes clip manufacturers and window assemblers to be burdened with large clip inventories. In addition, certain muntin clip designs require complex molds in the manufacturing process.
- The present invention is provided to solve the problems discussed above and other problems, and to provide advantages and aspects not provided by prior muntin clips of this type. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
- The present invention provides a muntin clip having an overall flexible support structure that allows the clip to be connected to a plurality of muntin bars and spacer frames having a variety of sizes. The muntin clip includes a base member adapted for connection to the spacer frame and a bar support adapted for connection to the muntin bar end.
- According to one aspect of the invention, the base member has a first segment, a second segment, and a mount structure.
- According to another aspect of the invention, the bar support extends from the base member and has a first segment extending from the first segment of the base member and a second segment extending from the second segment of the base member.
- According to another aspect of the invention, the bar support contains flexible bow members that are deformable to allow for connection to a variety of different muntin bars.
- According to another aspect of the invention, a flexible hinge member connects the first segment of the bar support to the second segment of the bar support, allowing the muntin clip assembly to move between an unfolded position and a folded position.
- According to another aspect of the invention, a tension mechanism exerts outward force on the first and second segments of the base member when the muntin clip assembly is in the folded position, allowing for enhanced connection to a spacer frame and also for connection to a variety of different spacer frames.
- According to another aspect of the invention, the tension mechanism includes a resilient spring member and an abutment member located on the base member.

- FIG.1 shows a
sash window 12 comprised of atop sash rail 16, abase sash rail 18 and a pair ofvertical stiles 20. Although not shown, thesash window 12 may be mounted, slidingly or otherwise, within a master frame, such as, in a single or double hung window arrangement as is well known in the art. It is also understood that other hardware can be incorporated into thesash window 12 as is known in the art. - As shown in
FIG. 2 , eachsash window 12 also includes a first pane of glass 24 and a second pane ofglass 26 mounted in parallel relationship to one another within an interior of thesash window 12. The first andsecond panes 24, 26 are spaced by aspacer assembly 28 located at a periphery of thepanes 24, 26. Thespacer assembly 28 comprises aspacer frame 30 and a seal orsealant 32. Thespacer frame 30 is generally tubular with a rectangular or square cross section as seen inFIG. 2 . Thespacer frame 30 extends about the entire periphery of the first andsecond panes 24, 26. A seal orsealant 32 is applied to an outer region of thespacer frame 30. When pressed between the first andsecond panes 24, 26, thespacer frame 30 forms an air tight seal between the twopanes 24, 26. - A muntin grid 34 (
FIG. 1 ) is positioned between the first and second panes ofglass 24, 26. Themuntin grid 34 is comprised of a plurality of interconnecting muntin bars 36. Eachmuntin bar 36 has a generally tubular and hollow construction. Various means of inter-connecting the muntin bars 36 are known to those of ordinary skill in the art. The connecting means are not further described herein and any means of connecting or joining the muntin bars 36 to one another may be utilized. As can be seen from the figures, the muntin bars 36 are so interconnected to form agrid 34 which is positioned between the first and second panes ofglass 24, 26. Extending towards and located at a periphery of thegrid 34 are a plurality of muntin bar ends 38. It is understood that thegrid 34 can take a variety of forms. -
FIGS. 4-5 depict thespacer frame 30.FIG. 4 shows only a portion of the length of thespacer frame 30. It can be seen that the spacer frame is generally U-shaped and includes alateral wall 56 and a pair ofvertical walls 58 extending in the same direction from thelateral wall 56. Eachvertical wall 58 includes an inwardly extendingshoulder 60 located near an end of its respectivevertical wall 58 distal from thelateral wall 56. Theshoulders 60 are separated by a distance A, defining anelongated opening 57 in the top of thespacer frame 30. Thevertical walls 58 each have a height B. Thelateral wall 56 has a length C and theshoulders 60 each have a length X. Spaced along a length of an inner edge of theshoulders 60 are a plurality of notches 62 (FIG. 4 ) adapted to receive themount structure 110 of theclip 100, to be explained. It can be seen that eachnotch 62 on oneshoulder 60 is generally opposed from a correspondingnotch 62 on theother shoulder 60. Theopposed notches 62 form a pair ofnotches 64. It can also be seen that two notch pairs 64 are usually located in proximity to one another. It is understood that the two notch pairs 64 are but one preferred embodiment. - A typical
muntin bar end 38 is shown inFIG. 6 , and includes opposedside walls 37 spaced by a distance W and opposedlateral walls 39 spaced by a distance T. Eachmuntin bar end 38 is normally hollow and rectangular (although other shapes are possible), and has aninterior cavity 40 withinterior walls 37 a andinterior walls 39 a formed byopposed side walls 37 and opposedlateral walls 39 respectively. Themuntin bar 36 may have a solid peripheral structure or formed from a flat segment of material and folded into a tubular structure. In such configuration, themuntin bar 36 has an open seam extending along a length of thebar 36. - A
muntin clip 100 mounts eachmuntin bar end 38 to thesash window 12, to be explained. One preferred embodiment of themuntin clip 100 according to the present invention is illustrated inFIGS. 7-17 . Eachmuntin clip 100 includes a base orbase member 102 and abar support 106. Thebase 102 is adapted to mount theclip 100 to thespacer frame 30, and thebar support 106 is adapted to connect theclip 100 to themuntin bar end 38. As explained in greater detail below, thebase 102 andbar support 106 each have flexible latching or support structure that enhances the connectability of themuntin clip 100 to thespacer frame 30 and themuntin bar end 38. Themuntin clip 100 is formed of afirst segment 100 a and asecond segment 100 b, joined in the middle by a foldable member, orflexible hinge member 108. Themuntin clip 100 can be moved between an unfolded position or unfolded configuration, illustrated inFIGS. 7-11 , and a folded position or folded configuration, illustrated inFIGS. 12-17 , by flexing of thehinge member 108. The folding of themuntin clip 100 is illustrated by the arrows inFIG. 7 wherein the foldable member is folded. As described below, themuntin clip 100 is preferably manufactured in the unfolded position, but is moved to the folded position during use. - The
bar support 106 is adapted to be inserted in theinterior cavity 40 of the hollowmuntin bar end 38 to support themuntin bar 36 within themuntin grid 34. Preferably, thebar support 106 fits relatively tightly within themuntin bar end 38. The preferred embodiment of thebar support 106 is shown inFIGS. 7-17 , and includes afirst segment 106 a and asecond segment 106 b connected by theflexible hinge member 108. Thefirst segment 106 a and thesecond segment 106 b are preferably substantially identical mirror images of each other. When themuntin clip 100 is moved to the folded position, thebar support segments bar support 106. Eachsegment bar support 106 has a means for connecting to a variety of different muntin bar ends 38, preferably including tworesilient bow members 116. Thebow members 116 are connected proximate thehinge member 108 and curve or angle outwardly and back inwardly, being connected to the base 102 in close proximity to each other. Thebow members 116 are preferably flexible and deflectable or deformable, yet still resilient. Theflexible bow members 116 can flex or deflect inwardly and outwardly to accommodate muntin bar ends 38 of different sizes. In alternate embodiments, thebow members 116 may take a different shape. In still other embodiments, thebar support 106 may take a different form, and may have a different means for connecting to a variety of different muntin bar ends 38. For example, in one embodiment, eachbar support segment bar support 106 preferably has two beveled surfaces 118 (FIGS. 11 and 12 ) proximate thehinge member 108 to facilitate insertion of thebar support 106 into themuntin bar end 38. - The
base 102 is adapted to be connected to thespacer frame 30 to connect themuntin bar 36 to thespacer frame 30. The preferred embodiment of thebase 102 is shown inFIGS. 7-17 , and includes afirst base segment 102 a connected to the firstbar support segment 106 a and asecond base segment 102 b connected to the secondbar support segment 106 b. Like thebar support 106, when themuntin clip 100 is moved to the folded position, thebase segments first base segment 102 a and thesecond base segment 102 b are preferably substantially identical mirror images of each other, except for the components of thetension mechanism 120, described below. The base 102 preferably has aplatform 104 and a means for connecting the base 102 to a variety of different spacer frames 30, which is preferably aflexible mount structure 110 attached to theplatform 104. Theflexible mount structure 110 is adapted to engage thespacer frame 30 to connect themuntin clip 100 to thespacer frame 30, as described below. Theflexible mount structure 110 preferably includes four latch bodies ormembers 112, two on eachbase segment latch bodies 112 preferably are attached at the bottom of theplatform 104 and extend downwardly, curving or angling back toward theplatform 104. This shape facilitates insertion of the base 102 into thespacer frame 30, and allows thelatch bodies 112 to be received in thenotches 62 of thespacer frame 30. When thebase 102 is inserted into thespacer frame 30, thelatch bodies 112 are received in thenotches 62 of thespacer frame 30 and engage theshoulders 60 of thespacer frame 30. In other embodiments, themount structure 110 may be configured differently, and may latch onto thespacer frame 30 by a different method, or may latch onto different locations of thespacer frame 30. For example, thelatch bodies 112 could cooperate with a shoulder portion 67 (FIG. 4 ) of thespacer frame 30 that is positioned between thenotches 62. Thelatch body 112 may also include a tab that engages an underside of theshoulder portion 67. As another example, theflexible mount structure 110 may contain flexible latching members that curve or angle upward and outward, forming a U-shape or a V-shape when viewed from the side. Accordingly, it is understood that the base 102 can utilize a variety of different latching structures. - The base 102 also includes a
tension mechanism 120, which is preferably aresilient spring member 122 located on thefirst base segment 102 a and anabutment member 124 located on thesecond base segment 102 b. Thespring member 122 is preferably a curved member or curved finger depending from the bottom of theplatform 104 of thefirst base segment 102 a, and then curving back upward. Thespring member 122 preferably has twoprongs 126 at the tip to create greater flexibility. Theabutment member 124 is preferably a flat wall projecting from the bottom of theplatform 104 of thesecond base segment 102 b. The flat surface of theabutment member 124 provides a surface for contact with thespring member 122. Thetension mechanism 120 preferably exerts an outward force F on the twobase segments base segments FIGS. 13 and 15 . When theclip 100 is moved to the folded position, thespring member 122 will contact theabutment member 124 and flex or deflect inwardly. When thespring member 122 is deflected, the resilience of thespring member 122 causes it to exert the outward force F on theabutment member 124. This enhances the connection to thespacer frame 30 as themuntin clip 100 may experience an inward bias when inserted into thespacer frame 30. Also, the base 102 can engage spacer frames 30 having different widths, because the base 102 will automatically “expand” to engage theshoulders 60 of awider spacer frame 30, and can “contract” to be forced into anarrower spacer frame 30. In other embodiments, thespring member 122 may be a different type of resilient and/or flexible member, and theabutment member 122 may be configured differently. In still further embodiments, theentire tension mechanism 120 may be configured differently, e.g., by including two spring members and no abutment member. Connection structure between the segments may also be provided that still allows movement of the segments. - The
flexible hinge member 108 connects theclip segments bar support segments hinge member 108 is preferably flexible and deformable, yet still resilient, allowing themuntin clip 100 to move between the unfolded and folded positions. Theflexible hinge member 108 preferably folds at a central portion of the strap. Thehinge member 108 is biased toward the unfolded position, and the resilience of thehinge member 108 causes thehinge member 108 to exert a continuous unfolding force on theclip segments clip 100 is being folded or when theclip 100 is in the folded position. The unfolding force of thehinge member 108 combines with the outward force F exerted by thetension mechanism 120 to push thebase segments flexible member 108 can be dimensioned or configured in varying fashions to affect the overall configuration of themuntin clip 100 when in the folded position. For example, themember 108 could be enlarged to provide for a wider dimensioned muntin clip for aparticular spacer frame 30. Themember 108 could also be configured to fold in multiple locations. Finally, it is understood that in one preferred embodiment, theflexible hinge member 108 is positioned at a distal end of thebar support segments member 108 can be positioned at other locations of themuntin clip 108. For example, themember 108 could be positioned at other locations of the bar support segments and could also be positioned on thebase segments - The
clip 100 has twosegments first segment 100 a includes thefirst base segment 102 a and the firstbar support segment 106 a. The firstbar support segment 106 a extends from thefirst base segment 102 a. Likewise, thesecond segment 100 b includes thesecond base segment 102 b and the secondbar support segment 106 b. The secondbar support segment 106 b extends from thesecond base segment 102 b. Terms such as “first,” “second,” etc., are used herein for purposes of reference only. It is understood that such designations can be interchanged. - As discussed, the
clip 100 is formed in the elongated, generally flat configuration as shown inFIG. 7 . Theclip 100 is moved to the folded position before use. Theclip 100 is folded along thehinge member 108 to bring the twosegments FIG. 7 . In the folded position, the twobar support segments bar support 106, and the twobase segments base 102. It is understood that a small gap or space is maintained between the twobar support segments base segments FIG. 17 illustrates the connection of the foldedclip 100 to themuntin bar end 38 and thespacer frame 30. Thebar support 106 of the foldedmuntin clip 100 is pushed into thecavity 40 in themuntin bar end 38 and provides an interference fit with the interior walls of themuntin bar end 38. Thebow members 116 flex inwardly, if necessary, to accommodate for amuntin bar end 38 having a narrower width. Thebase 102 of the foldedmuntin clip 100 is then pushed into thespacer frame 30 so that thelatch bodies 112 are received in thenotches 62 and engage theshoulders 60 of the spacer frame. As described above, thetension mechanism 120 allows the base 102 to expand and contract to fit spacer frames 30 of different sizes. It is understood that theclip 100 can experience an inward bias when inserted into thespacer frame 30 and also experience an outward bias from thetension mechanism 120. - As discussed, the
muntin clip 100 is typically formed in an injection-molded process. Theclip 100 is formed in the generally flat position as shown inFIG. 7 . By molding in this configuration, a conventional open/close tool is used. Thus, a simpler mold configuration can be used and sliding mold parts are unnecessary. It is understood that the mold can include cooperating mold parts formed to correspond to the structure of themuntin clip 100 as shown inFIG. 7 . It is further understood that the mold parts can each include a channel that will cooperatively form theflexible hinge member 108. Thus, the channel will typically be a generally straight groove-like portion cut into each mold part. Molten plastic is then injected into the mold wherein the muntin clip as shown inFIG. 7 is formed. Once the injection is complete and the clip is formed, the mold parts can be easily separate and theclip 100 can be ejected from the mold. - Thus, it is understood that simple methods are employed with the
muntin clip 100. First, themuntin clip 100 is formed in an injection molded process using a more simple mold configuration than many other prior art configurations. Once formed, themuntin clip 100 remains in the generally flat configuration. For connection in a window assembly, themuntin clip 100 is folded along theflexible member 108. The bar support segments are inserted into a muntin bar end and the base segments are inserted into the spacer frame. The structural configurations of themuntin clip 100 as described above allow the clip to be utilized in muntin bars and spacer frames of varying sizes. As previously discussed, thebar support 106 and the base 102 can have different structures to allow for these flexible connections. It is understood that thebar support 106 andbase 102 could have structural configurations such as those shown in commonly-owned U.S. patent application Ser. Nos. 11/186,387 and 11/298,304, which Applications are incorporated by reference herein and made a part hereof. These structures could be slightly modified and incorporated with theflexible member 108 as discussed above to provide a muntin clip having an unfolded position and a folded position. - The flexible components of the bar support of the muntin clip described above permit a single clip to be connected to any of a variety of different muntin bars having a variety of different dimensions and configurations. Similarly, the flexible mount structure and tension mechanism of the base permits a single clip to be connected to any of a variety of different spacer frames having a variety of different dimensions and configurations, and having openings of a variety of different widths. Thus, with the muntin clip as described above, the necessary number of differently-sized muntin clips can be drastically reduced. This reduces inventory costs, additional tooling costs, and other costs associated with having to manufacture and store a large number of differently sized muntin clips. In addition, the number of spacer frame assemblies can be reduced. Further, the clip can be manufactured in the unfolded position, which reduces the complexity of the mold. The mold can be a more simple, straight open/close tool. Accordingly, the need for sliding motion of mold parts is eliminated. These features extend the life of the tool through increased strength and less unexpected or incidental damage to the tool. In addition, because of the reduced complexity, the cycle time associated with forming the muntin clip is reduced.
- While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying Claims.
