Description
METHOD AND APPARAT~J_S FOR SEALING A FENS 7CRA~'ION FRA11~IE
B~act~ground of the Invention Field of the Invention The present invention relates in general to a method and apparatus for sealing a corner of a fenestration sash frame and, more particularly, to a method and apparatus which provides structural support and fluid containr~nt to a f~estration sash frame.
io Description of the Prior Art It is well known in the art to provide a sealing material on comer brackets for insulating a sash in a manra3r such as that taught in U. S. Letters Patent No.
6,401,428 to Glover ~ al, and U. S. Letters Patent No. 4,145,150 to Rafeld. One drawback associated with ~s such prior art constructions is the inability to provide sealing material around the entirety of the corner bracket. Failure to completely surround the corner bracket with sealing material increases the likelihood of moisture and/or other elements intruding into or through the frame members.
Accordingly, it would be desirable to provide a method for providing a sealant 2o material around the ~tirety of the surface of the corner bracket coming into contact with the frame members. While it is known in the art to lap corner brackets with an insulating tape, such tape may tend to gap, thereby preventing a solid seal and inviting the intrusion problems noted above.
It is also known in the art to provide sealant material on non-mitered fenestration 25 spacer assemblies in a manner such as that taught by U.S. Letters Pat~t No.
4,651,482 to Boors. Such prior art devices, however, are designed for more fragile spacer assemblies and do not provide for the closure and rigidity required of frame members. It would be, therefore, desirable to provide a corner bracket assembly with a sealant material which added structural support to a fenestration frame.
It is also known in the art to connect frame member corners by heating the corners and pressing them together. Such methods, however, often do nc~t provide adequate support s structure for the final frame, produce weld flashes which must be subsequently removed, and often require additional painting, adding to the cost and labor associated with construction It would be, therefore, desirable to provide a low-cost construction method which provided a solid seal and added structural support to the sash frame assembly, without the additional time and cost associated with weld flash removal or other subsequent steps.
io The difficulties encountered in the prior art discussed hereinabove are substantially eliminated by the present invention.
~mmary yf lfhe Invention In an advantage provided by this invention, a corner bracket is integrally sealed with a fenestration sash frame assembly, adding structural support to the frame.
i s Advantageously this invention provides a fenestration sash frame assembly which eliminates the need for subsequent steps of flash weld removal and repainting.
Advantageously, this invemion provides a more efficient sash frame member production method.
Advantageously, in a preferred example of this inv~tion, a corner bracket is provided zo with first and second longitudinally extending legs. Each leg is provided with means for engaging an interior surface of a sash frame member, and mear~ for retaining a flowable material in contact with the interior surface of the sash frame member. Means are provided for securing the legs to one another, and means are also provided for directing a flowable material to both of the retaining means.
Preferably, the corm bracket is provided with a port on an inward surface of the sash frame. The corns bracket is inserted into mitered fray membem and a flowable material is injected through the injection port to fully surround the corner bracket and create a seal between the corner bracket and sash fra~x~e members.
Brief Descriution of the Drawinss The present invention will now be described, by way of example, with reference to the accompanying drawings in which:
Fig. 1 illustrates a top perspective view of the improved fenestration frame of the 1o present invention;
Fig. 2 illustrates a top perspective view of the lower sash of the frame of Fig. 1;
Fig. 3 illustrates a perspective view in partial cross-section of the corner of the lower sash of Fig. 2;
Fig. 4 illustrates a perspective view of the corner bracket of the present invention;
t s Fig. 5 illustrates a p~spec~ive side view in cross-section of the present invention, take along lines 5-S of Fig. 1; and Fig. 6 illustrates a perspective view of the corner of the window frame secured by the method of the present invention 2o Detailed Dcacrintion of the Preferred Embodiment A window according to the preset invention is shown g~erally as (10) in Fig.
1.
The window (10) is provided with a franne (12), including a first side jamb (14), a second side jamb (16), a sill (18) and a head jamb (20). Slidably coupled arithin the frame (12) are an upper sash (22) having a frame (24) and a lower sash (26) having a frame (28).
1n the 25 preferred embodiment the frames (24) and (28) are constructed of pultrusion, but may be constructed of aluminum, polyvinylchloride, or any other desired type of material known in the art.
As shown in Fig. 2, the frame (28) of the lower sash (26) is provided with a left stile (30), a right stile (32), a top rail (34) and a bottom rail (36). As shown in Fig. 3, the le$ stile s (30) is provided with a mitered corner (38), and the bottom rail (36) is also provided with a mitered corner (40). Shown in Fig. 4 is the comer bracket (42) of the present invention. The corner bracket (42) may be constructed of any suitable material. ~n the preferred embodiment, the corner bracket (42) is constructed of nylon, but may be constructed of any suitable material known in the art. The comer bracket (42) is provided with a first longitudinally extending leg (44) and a second longitudinally exuding leg (46). The legs (44) and (46) are coupled to one another by a corner piece (48), integrally molded as part of the corner bracket (42).
As shown in Fig. 4, the corner bracket (42) is constructed with a top face (s0) and a bottom face (52). In the preferred ernbodinamt, the top face (SO) is provided with a plurality i s of fins (54) which may be of any suitable height, width and length, for the purpose of retaining the corner bracket (42) within the rails (34) and (36) and stiles (30) and (32). Fins (54) may also be provided on the bottom face (52) of the corner bracket (42).
The corner bracket (42) is also provided with an injection port (56~ defining a hole (58). Positioned below the injection port (56) is a curved diffuser (60) which feeds a deep recess (61) which, 2o in turn, feeds to a shallow recess (62). The messes (61) and (62) are provided on either side of the corner bracket (42) and are bordered by fins (54) which serve to direct and maintain sealant material (78) within the recesses (61) and (62). The recesses (61) and (62) may be of any suitable dimensions, but are preferably in fluid communication with the lateral and internal abutting edge of the rail (36) and stile (30) within which it is positioned.
2s Accordingly, when the seating material (78) is injected, as explained fore fully below, the sealing material (78) creates a fluid-tight seal along the lateral and internal edges of the rail (36) and stile (30). Preferably, the recesses (61) and (62) do not w~tend along the outer abutting edge of the rail (36) and stile (30). Since the outer abutting edge is typically shielded by the window frame (12), little moisture esters the sash (26).
Additionally, since s this arrangement allows for the influx and egress of fluid, the sash (26) does not develop pressure as the temperature increase, and any moisture entering the sash (26) simply weeps out of the bottom corners.
As shown in Figs. 3, 4 and S, when it is desired to construct the frame (28) of the lower sash (26), the first leg (44) is inserted into an interior (64) of the left stile (30), defined io by an interior surface (66) thereof Similarly, the second leg (46) is inserted into an imerior (68) defined by the interior surface (70) of the bottom rail (36). As shown in Fig. 5, both the left stile (30) and bottom rail (36) are provided with small cutouts (72) on their respective inward faces (74) and (76) to accommodate the injection port (56). As shown in Fig. 5, in addition to serving as material retainers, the fins (54) serve to resiliently bias the corner 1s bracket (42) against the interior surface (66) of the left stile (30) and interior surface (70) of the bottom rail (36).
Once corner brackets (42) have been so installed in each coxnex of the frame (12), the frame is clamped in a manner such as that known in the art, and the flowable sealant material (78) which, in the prefer embodiment is a ur~har~e reactive hot ~It, or similar flowable 2o adhesive, such as those known in the art, is injected through the hole (58) of the injection port (56). As the sealant material (78) moves through the hole (S8), the sealant material (78) contacts the diffuser (60), which directs the sealant material (78) toward the recesses (61) and (62). As the sealant material (78) moves across each of the legs (44) and (46), the fins (54) near the recesses (61) and (62) maintain the sealant material (T8) in the recesses (61) and (62~ forcing the sealant material (78) around the entirety of the Corner bracket (42) covering both the top face (50) arui sides of the comp bracket (42).
As shown in Figs. 4 and 5, this directing of the sealant material (78) causes the sealant material (78) to form a fluid-tight barrier between the interior surfaces (66) and (70) of the Ieft stile (30) and bottom rail (36) of the frame (28) of the Iower sash (26) and the corner bracket (42) itself. The fins (54) act to retain the sealant mat~iat (78) ~d frame (28) in place as the sealant material (78) dries. ~s the sealant material (78) provides structural support to the frame (28), the frame (28) may be unclamped and moved slang for additional processing before the sealant material (78) has completely hardened.
io As shown in Figs. 4 and 6, the frame {12) of the window (10) itself may be secured by the foregoing method. If desired, screws (80) may be provided through the frame (12) to gage the corner bractcets (42) to add additional rigidity and stability to the frame (12).
Although the invention has been described with respect 'to a preferred embodiment thereof; it is to be also understood that it is not to be so limited, since changes and i s modifications can be made therein, which are within the full intended scope of this invention as defined by the appended claims. As an example, the sealing method of the preset invention may be used in association with sashes, doors or any desired frame assembly.
