6 Claims. (Cl. 160-90) This invention relates to improvements in window assemblies and particularly to an improved window frame assembly designed for use with swinging window sash and specifically to sealing means provided to form a weatherproof seal between the sash and the frame or between the meeting rails of :a pair of swinging sash pivotally supported within the frame.

One of the difficu'lties encountered in the use of swinging window 'sash, whether of the French window type hinged on vertical pivots or of the awning window type hinged on horizontal pivots, is that relating to effectively sealing the window sash against the weather. This invention relates to accomplishing such effective sealing.

While the invention is illustrated as embodied in an awning type of window structure, it is obviously adaptable to swinging Windows mounted for pivotal movement upon vertical axes as well as on horizontal axes.

More particularly an object is the provision of a window frame in an assembly of the character described wherein the frame is provided interiorly along its two jamb portions and along the header and the sill portion with a flange that projects inwardly of the plane of the frame and substantially parallel thereto and also substantially midway between the inner and outer faces of the frame which flange is adapted to present opposed faces one of which is engaged by the swinging sash to form a tight seal therewith when the sash is closed and the other of which is engaged by a removable screen or storm sash when the same is supported within the frame and wherein such flange is modified and provided with sealing means :as hereinafter described to embody the primary features of my invention.

More specifically such flanges as are provided on the two jamb portions and the header and sill portion of a window frame are disposed within the same plane and form substantial continuations of each other and each such flange is provided on its two opposite faces with grooves which are offset each other and which extend lengthwise of the flange and each of which is adapted to receive and support a sealing gasket as hereinafter described. Each such groove is so formed that a sealing gasket mounted therein is securely held in place and exhibits a resilient linear portion which projects outwardly from the face of the flange and is adapted to be engaged by a sash element to form a secure seal therewith.

nited States. Patent The frame member is further provided with a second 'ice vide a tight seal between the meeting rails of the two sash.

Further objects, advantages and meritorious features will more fully appear from the following specification, claims and accompanying drawings, wherein:

Fig. l is an elevation of a window frame assembly embodying this invention;

Fig. 2 is a vertical sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a horizontal sectional view taken on line 33 of Fig. 1;

Fig. 4 is a fragmentary sectional view taken through one of the frame members provided with the sealing gaskets mounted Within the grooves therein;

Fig. 5 is a view similar to Fig. 4 but showing both gaskets engaged by their-respective sash;

Fig. 6 is a fragmentary perspective of one of the gasket members; and

Fig. 7 is a cross sectional view similar to Fig. 4 showing a modified form of gasket supported within the grooves 34 of the flange 32.

This invention relates to that portion of the frame and window assembly which has to do with the sealing of the two sash against the frame or the sealing of the sash with respect to each other and does not have to do with the operating mechanism for the swinging sash.

In the drawings, a window frame is shown as provided with a sill port-ion 10, a header portion 12, and a pair of similar jamb portions 14 which extend between the header and the sill in the conventional manner. In the construction shown, an upper sash is indicated as U and a lower sash as L. The upper sash is shown as provided with a glass pane glazed therein and a lower sash is shown as similarly provided. The lower rail of the lower sash has a face portion 16 which overlaps a portion of the sill of the frame and the upper rail of the upper sash has a face portion 18 which overlaps the face plate 20 carried by the header of the frame. Each sash has a pair of side rails 22 which close the open side of the channel-shaped jamb portions 14 of the frame, as shown in Fig. 2 when the sash are closed thereagainst.

In Fig. 3, a sliding bar 24 is illustrated as mounted within the jamb portion of the frame upon a channelshaped support 26 in a manner more specifically described in my copending application this day filed. The general construction of the operating mechanism, except for this specific kindof support for the sliding bar, is shown in my applications Nos. 291,848 and 291,849 filed June 5, 1952. Inasmuch as this invention does not concern itself with this operating mechanism, such is not further disclosed or claimed herein.

it will be noted'that the sill portion, the header portion and each of the twojamb portions of the window frame are channel-shaped in cross section. These portions are so secured together in the rectangular frame that their channels open outwardly. These channels are closed by the swinging upper and lower sash when such sash are closed, except to the extent that the face plate 20 serves to partially close and overhang the header as illustrated in Fig. 2. Each of these channel-shaped frame portions has an inner wall which is indicated by the numeral 5t) and which has a height substantially half that of the outer wall of the channel and which is formed so as to exhibit a flange 32. thatextends lengthwise thereof and substantially perpendicular thereto and which flange is adapted to be engaged on one .side by the swinging sash and on the opposite side by removable screen or storm window sash. The screen sash is here shown and such is indicated by the letter S. V

This fianget32is provided on opposite faces with sealing gasket receiving grooves 34. These grooves are similar. Each is generally keystone shaped in cross section; i. e., it has a bottom portion from which its two side walls generally converge as they project toward the adjacent faces. One side wall has a portion 36 which is disposed directly adjacent to the bottom of the groove and a portion 38 extending outwardly therefrom to the face of the flange and forming a converging portion of the side wall. This is shown particularly in Fig. 4. The opposite side wall projects at a converging angle throughout its extent. The two grooves are shown as offset each other, not only within the width of the flange but offset each other within its thickness.

Within each groove is mounted a sealing gasket. Such gasket is indicated by the numeral 40. This gasket is generally V-shaped in cross section. One side wall of the V-shape indicated as 42 is substantially thicker than the opposite side wall indicated by the numeral 44. This thicker side wall seats against the bottom of the groove 34. The gasket may be formed of rubber or other suitable resilient and eflicient sealing material. The side wall 44 projects outwardly beyond the face of the flange 32 in the form of a lip which projects beyond the groove when the gasket is disposed uncompressed as it is in Fig. 4.

When the gasket is engaged by the adjacent sash, as shown in Fig. 5, such Wall or lip portion 44 is urged inwardly of the groove and may be urged almost completely within the thickness of the flange.

In Fig. the upper swinging sash is shown as engaging the gasket on the adjacent side of the header flange 32 and a screen sash frame is shown as engaging the gasket on the opposite side of the header frame 32. These two sash cooperating with the two gaskets on the opposite sides of the flange form a particularly tight and secure weather seal and this is true throughout the entire circumference of the window frame. The seal is shown also between the meeting rails of the two sash. In Fig. 2 the lower sash is illustrated as provided with an upwardly projecting flange 48 which has a groove within which a sealing gasket 50 is disposed. This groove and the sealing gasket 50 are of the same character as the groove 34 and gasket 40 hereinbefore described. The upper sash has a flange portion 52 which is adapted to abut the gasket 50 to form a tight seal between these two meeting rails of the upper and lower sash.

The window frame is provided upon the same side wall 30 hereinbefore described as provided with a flange 32 with a second flange portion indicated as 54 shown parlicularly in Figs. 2 and 3 which flange portion 54 extends parallel to the flange 32 and is spaced therefrom and is angular in cross section, as shown in Figs. 2 and 3. This flange portion 54 is of low height as compared with the flange 32 and is adapted to be engaged by a fastening device mounted on the screen frame or storm sash frame. In Figs. 2 and 3 such fastening device is illustrated as an eccentric 56 pivoted as at 58 on the screen and which eccentric is rotatable as illustrated in such figure to engage behind the flange 54 and urge the screen or storm sash against the gasket mounted within the adjacent face of the flange 32.

The swinging window sash is of course urged down to its seat against the sealing gasket carried by the flange 32 by an operating mechanism which is employed to manipulate the swinging sash. Both sash structures therefore are held tightly against the sealing gasket and an effective weatherproof seal is formed around the margin of the window frame.

The preferred form of gasket is that shown in the first 6 figures of the drawing. Fig. 7 shows a modified form of the gasket wherein the base of the rubber strip comprises a series of linearly extending spaced legs or ribs 61. Four of these are shown. These ribs seat within the channel but are sufficiently flexible and resilient to permit the projecting ridge 63 to be depressed toward the bottom of the channel to be received therein. On one side of the flange 32 in Fig. 7, a dottled outline member which might be a sash frame is shown as depressing such ridge 63 into the channel.
