Claims. (Cl. 189--o5) This invention relates to window structures and embodies,more specifically, improved components employed in metallic window structures to provide a weather tight assembly.

For many years, metallic window structures have been standard in building operations involving large structures such as ofiice buildings and the like, the material of these metallic windows usually being steel. In recent times, light metals such as aluminum have been found to be particularly well suited to building structures, and window structures havebeen made out of such materials. For example, in copending application Serial No. 436,191, filed June 11, 1954, by Herman C. Knebel, a metallic window structure is disclosed which is particularly susceptib le of being manufactured from the lighter metals such as aluminum.

in metallic window structures such as discussed above, it is always a problem to provide suitable structure for rendering the windows weather resistant. Accordingly, it is an object of the present invention to provide structure serving to weather proof metallic window structures.

It is another object of the invention to provide a weather strip sealer which forms an effective seal with any surface it may engage.

It is a further object of the invention to provide metallic window structure in which a variable width mullion may be formed to accommodate standard size windows.

These and further objects of the invention are accomplished by disposing at sliding points of contact between metallic window sash and supporting structure novel weather stripping in engagement with an elongated weather strip sealer. The latter element is formed of resilient material and provided with longitudinal forward- 1y facing ridges on a resilient preferably arcuate portion enclosing a longitudinal cavity, such sealer cooperating with weather strip having aflat surface urged against the ridges. In' addition, the weather strip sealer may be employed in other applications such as in the head and sill structure in order torender the entire window weather tight. If desired, a stiffening liner may be disposed in the weather strip sealer.

In order to accommodate windows of standard sizes, a further novel feature of the invention comprises the use of a selected one of a plurality of mullion forming means to space back to back jambs together to form a mullion of variable width.

These and further objects and advantages of the invention will be more readily understood when the following description is read in' connection with the accompanying drawings in which:

Figure 7 is a perspective view, partially broken away, illustrating the weather strip sealer of Figure 6 and Figure 8 is a perspective view showing the weather stripping of Figure 6.

Referring to an illustrative embodiment of the invention and particularly to Figure 1, an upper sash 10 and a lower sash T1 are slidably mounted in a conventional window frame formed by a head 12, a sill 13, and jambs IJ-i and 15 joining the ends thereof. The foregoing structure may be mounted in masonry 16 (Figures 2 and 3) in any conventional fashion such as by means of head strap hangers T7 and sill strap hangers 18, for example.

As best shown in Figure 3, the jamb 14 is formed of side plates 19 and 20 joined by a U-shaped support 42, an outer plate 21, and an angled inner plate 22, all formed integrally as, for example, by means of extruding the metals in a conventional manner. Caulking compound 23 seals the outer plate 21 to the masonry 16 and in order to further strengthen the structure, side strap hangers 24, joined to the masonry 16 in any desired manner, may be fastened to the side plate 20 by means of nut and bolt combinations 25.

The inner extremities of the outer and inner plates 21 and 22 are formed with channels 26 and 27, respectively, provided with inwardly extending flanges 28 and 29, respectively, on opposite sides of the channels. These are shaped to receive elongated pieces of weather strip sealer 36 as will be apparent from Figure 6.

The weather strip sealer 30, best shown in Figure 7, is formed of a resilient material such, for example, as natural or synthetic rubber, and comprises a relatively thin preferably arcuate front portion 31 enclosing a longitudinal cavity 32, the remainder of the cavity being defined by angled walls 33 and 34 forming the inner surfaces of a rearwardly extending block 35. Shoulders se and 37 are found on the block 35 and cooperatewith the flanges Z8 and 29 in the channels 26 and 27, respectively.

In order to provide an effective seal with a surface it engages, the weather strip sealer 30 carries on the arcuate portion 311 a plurality of longitudinal forwardly extending ridges 38. Preferably, the entire sealer 30 is an integrally molded piece as shown in Figure 7. If desired, a C-shaped iiner 39, preferably formed of springy metal although other suitable materials may be employed, may be inserted in the cavity 32 to back the arcuate port-ion 31 and lend greater stifiness to the entire sealer 30 and extend its useful life. It should, however, be understood that the liner 39 may be omitted in the event sufficient stifi'ness is obtained by using the sealer 30 alone. For example, it has been found that the metal liner may be omitted from the sealer 30 in most instances when it is employed as shown in Figure 6.

In the central plane of the jamb, a parting bead 40 is supported by a U-shaped snap bracket 41 cooperating with the U-shaped support 42 which joins the side plates 19 and 2t). Integral with the bracket 41 are channel closure plates 43 and 44 extending obliquely to the transverse plane of the inner extremity of the parting bead 40 and then extending parallel to the side plates 19 and 20 to lie in spaced relation to the adjacent edges of the outer and inner plates 21 and 22, respectively.

It will be apparent that the assembly constituted by the parting bead 40, the bracket 41 and the plates 43 and 44 may be snapped into position on the support 42 to form substantially enclosed parallel channels 45 and 46 within which are positioned spring balances 48.

Returning to the parting bead 4% it will be seen that it is formed in a generally T-shaped section to provide channels 49 and 50 formed with inwardly extending flanges 51 and 52, respectively, which receive elongated pieces of the weather strip sealer 30.

The sash structure adapted to be used in connection with the above-described jarnb structure is illustrated in Figures 2 and 3 and includes the upper and lower sashes and 11. The sides of each of the sashes it) and If include recesses 53 and 54 formed with shoulders 55 and 56, respectively, plates 57 and 58 extending therefrom parallel to the planes defined by the outer vertical edges of the sashes 10 and 11 but slightly removed toward the central vertical sash plane.

Secured in the recesses 53 and 54 is weather stripping 60, best illustnated in Figure 8, formed of a strip of spring like metal. Preferably, one edge of the strip is bent back on itself to form a helm 61 while the other side of the strip it bent to form an obtusely angled section 62;. A further bend in the strip provides for an obliquely extending section 63 which cooperates with the shoulders 55 and 56 to secure the weather strip 68 in the recesses 53 and 54.

As clearly shown in Figure 6, the weather strip 60 engages the Weather strip sealer 30 and, due to the obtuse angle between the main body of the strip 60 and the section 62, the strip 60 is resiliently urged against the ridges 38 in order to effect an eflicient weather resistant seal between the sash and the jamb structure. It will be apparent from Figure 6 that since the weather strip 60 provides a surface extending substantially beyond the sealer 30, small differences in the sizes of the sashes 19 and 11 and the jamb structure will not interfere with this sealing action. In addition, the ridges 38, which would normally define an arcuate path, are urged into a straight path by the strip 60 which depresses the sealer 30. As indicated in Figure 6, the strip 60 is preferably spaced a small distance from the plate 58 in order to aid in cushioning the sash.

Referring to Figure 2, the meeting rails of the sashes 10 and 11 are sealed by means of a flange 64 adapted to be received within a longitudinal pocket 65 within which weather stripping 66 is provided. Additional weather stripping 67 may be employed, if desired, to insure a tight joint between the sashes 10 and 11.

Transversely extending recesses 68 and 69 formed in the bottom rail of the lower sash 11, similar to the recess 26, receive the weather strip sealer 30 in order to weather proof the joint between the sill 13 and the sash 1f. Preferably, the metal liner 32 is disposed in the stripping 38. In addition, transverse recesses 78 and '71 are carried by the head 12 and receive pieces of the weather strip sealer 30 which cooperate with vertical surfaces on the upper sash 10 to effectively seal this joint. The remaining portions of the sashes 10 and 11 are formed in any desired fashion in accordance with conventional practices.

Examining the structure illustrated in Figure 4, a mullion formed from jambs and 15a is illustrated, the jamb 15a being identical to the jamb 14 and the jamb 15 being slightly modified to provide side plates 19a and a. Interposed between the side plates 19, 19a and 20, Ztla are mullion forming members 72 which cooperate with the jambs 15 and 15a to space them a desired distance apart.

More specifically examining one side of the mullion, a plate 73 forms the head of the member 72, a transverse strip 74 being integral with the head 73 and contiguous to the plate 19a. The strip 74 is sealed by a 4 resilient sealing strip 75 supported by a flange 76 on the plate 19a. An offset portion 77 of the member 72 lies contiguous to the plate 19 between a flange 78 formed thereon and a T-shaped flange 79 extending from the plate 19a. Provided between the flange 7'8 and the head 73 is a further rubber sealing strip 80. Leading from the offset portion 77 is a leg 81 effectively locked into the T-shaped flange 79. In other respects, the companion parts of the mullion follow the window structure described above in connection with Figure 3.

In fitting the jambs 15 and 15a together, the members 72 are first locked to the plates 19a and 20a and subsequently, the jamb 15 urged into position as shown in Figure 4. It will be apparent that the structure illustrated in Figure 4 provides a mullion having the least possible width since the T-shaped flanges 79 abut the plates 19 and 20.

Turning next to Figure 5, in the event it is desirable to provide a mullion of greater width to accommodate standard size windows in some particular installation, a mullion forming member 72a, similar in many respects to the member 72, is provided to space the jambs 15 and 15a. Since in this instance a mullion of greater width is desired, the plates 19, 19a and 20, 20a must be spaced further apart and accordingly, heads 73a must be of greater width than the heads 73 and the offset portions 77 must be divided into two portions 77a and 77b to engage the flanges 78 and sealing strips 75a, respectively. In addition, legs 81a cooperate with the T -shaped flanges 79 in order to lock the members 72a to the jambs 15. Of course, mullion forming member provided with heads 73 of any width may be employed to form mullions having any desired dimensions.

From the foregoing, it will be seen that a window structure is provided that may be simply formed from metallic sections and rapidly assembled. In addition, this structure provides for effective weather tight sealing between the sash and jamb structures under all conditions and regardless of small size variations in the manufacturing operations. Furthermore, mullions of varying widths may be formed in order to accommodate standard size windows.

It will be apparent that while metal structure has been referred to in describing an illustrative embodiment of the invention, certain plastic materials may serve satisfactorily in view of the facility with which they may be extruded. Moreover, it will be understood that the abovedescribed embodiments of the invention are illustrative only and modifications thereof will occur to those skilled in the art. Therefore, the invention is not to be limited to the specific apparatus disclosed herein but is to be defined by the appended claims.
