DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1-5 illustrate a window 20 in accordance with a first exemplary embodiment of the present disclosure. Window 20 includes a window frame 22 having top, bottom and side rails. A fixed sash 24 is secured to frame 22. Window 20 typically also would include a movable sash, which is not illustrated in FIGS. 1-5 for clarity. Fixed sash 24 has top, bottom and side rails in a generally rectangular geometry. The rails of window frame 22 and fixed sash 24 preferably are of extruded metal or plastic construction, such as aluminum construction or fiber-reinforced resin construction. Among other channels formed in the rails of frame 22 and sash 24 are a channel 26 in the rails of frame 22 and a channel 28 in the rails of fixed sash 24. At least one sash clip 30, and preferably a plurality of uniformly spaced sash clips 30, are received in channels 26, 28 fixedly to secure fixed sash 24 to window frame 22.
Sash clip 30 includes a base 32 having opposed flexible resilient spring legs 34, 36. Spring legs 34, 36 have respective outwardly extending feet that are received in corresponding portions of channel 26 (FIGS. 2 and 4) to secure sash clip 30 to frame 22. A trapezoidal head 38 extends from base 32 and is received by press fit in channel 28 of fixed sash 24 (FIG. 2). In the embodiment of FIGS. 1-5, there preferably is a clip plunger 40 on head 38. Plunger 40 preferably is of compressible construction to engage and be compressed by the opposing wall of channel 28 in fixed sash 24, as shown in FIG. 2, to retard rattling of fixed sash 24 on window frame 22. Sash clips 30 preferably are disposed at uniform spacing around fixed sash 24, such as every foot. Sash clips 30 preferably are installed in the rails of window frame 22 before the rails are welded to each other to form the rectangular window frame. The trapezoidal construction of head 38 allows fixed sash 24 to be forced over the heads of the sash clips fixedly to secure fixed sash 24 to window frame 22.
FIGS. 6 and 7 illustrate a window 42 having a window frame 44, a fixed sash 46 and a moveable sash 48. Sash clips 50 mount fixed sash 40 to window frame 44. Sash clips 50 have a base 52 with opposed legs 54, 56 and respective feet for securement within channel 26 of frame 44. Head 58 of clip 40 includes a pair of opposed legs 60, 62, the outsides of which form a generally trapezoidal geometry. Again, base 52 of spring clip 50 preferably is slid into channel 26 of frame 44 before the frame rails are welded to each other. Legs 60, 62 of head 58 are resiliently compressed toward each other as fixed sash 46 is assembled to frame 44 by forcing the heads 58 of the several sash clips into channel 28 of sash 46. Clips 50 can be short individual clips as illustrated in FIG. 3, or an extruded lineal clip that extends along all three sides of the fixed sash
FIGS. 8, 9 and 11 illustrate a window 64 in accordance with a further exemplary embodiment of the present disclosure, including frame 44, fixed sash 46 and movable sash 48 as in the embodiment of FIG. 6. Sash clips 66 secure sash 46 to frame 44. Each sash clip 66 includes a base 68 and a head 70. Base 68 is generally T-shaped having opposed outwardly extending feet 72, 74 slidably received in channel 26 of frame 44, again preferably before welding the frame rails to each other. Head 70 has a rounded external contour and outwardly extending spring arms 76, 78 for engaging opposed edges of channel 28 and retaining spring clip head 70 in the channel. A third spring arm 80 extends longitudinally from head 70 for engaging the opposed base of channel 28 to prevent rattling of fixed sash 46 with respect to frame 44. Clip 60 preferably is an extruded lineal clip that extends along all three sides of the fixed sash (FIG. 11).
Sash clips 30, 50 and 66 preferably are of molded plastic construction.
FIG. 10 illustrates a window 82 including a fixed sash 84 secured to a window frame 86 that also mounts a movable sash 88. Fixed sash 84 is mounted to frame 86 by uniformly spaced sash clips 90. Sash clips 90 in this embodiment can be of spring metal construction, including a base 92 received in a channel 94 in fixed frame 86, and a head 96 received in a channel 98 of fixed sash 84. Sash clip 90 is of generally C-shaped construction, and resiliency of leg 96 with respect to leg 92 suspends fixed sash 84 within window frame 86 and prevents rattling. Head 96 of sash clip 90 is angled toward movable sash 88 to prevent fixed sash 84 from being pulled out of frame 86.
There thus has been disclosed a window having a window frame with a fixed sash mounted by a plurality of sash clips, which fully satisfies all of the objects and aims previously set forth. The disclosure has been presented in conjunction with several exemplary embodiments, and additional modifications and variations have been discussed. Other modifications and variations readily will suggest themselves to persons of ordinary skill in the art in view of the foregoing description. The disclosure is intended to embrace all such modifications and variations as fall within the spirit and broad scope of the appended claims.
