ATTORNEY United States Patent 3,068,617 GLAZING GASKET Bernes R. Borski, Houston, Tex., assignor to F. H. Maloney Company, Houston, Tex., a corporation of Texas Filed Jan. 11, 1961, Ser. No. 82,111 Claims. (Cl. 50-120) This invention relates to wall panel construction, and particularly it relates to gaskets used for sealingly retaining panels used in building wall construction.

One form of building wall construction that is being used with some frequency is one which requires the use of concrete wall panel frames which are precast in a mold and installed in the wall of the building. The frames are provided with means for retaining therein panels of glass, if the frames are for windows, or of other materials, if an opaque wall is desired. Such means include the use of a combination of a metal member and a rubber gasket. One method suggested comprises molding the frame with an intergral inwardly extending annular metal insert, to which glass panels, for example, may be attached, as by means of sealing strips such as are described in US. Patent 2,189,138. As may be seen in the above patent, sealing strips join coplanar sheets of material in sealing relationship. The sealing strip is first placed on the insert, so that it extends all the way around the inside of the frame, and the window pane is then put into place.

A major problem with this procedure is the difficulty of obtaining a permanent seal between the annular metal insert and the cast frame, so that the wall panel is impervious to wind and rain, since metals are subject to corrosion. An aluminum insert has been found most satisfactory, but these are expensive, and the concrete causes rapid corrosion of aluminum, so that these inserts do not provide a permanent structure.

According to the present invention, the frame, whether of concrete or of other material, is made with an annular inwardly directed groove. A glazing gasket is sealingly engaged in the groove, and the glass or other wall panel is sealingly retained by the glazing gasket.

For a better understanding of the invention, reference is now made to the drawings, wherein:

FIGURE 1 depicts a cast window frame having a glass pane retained by a glazing gasket;

FIGURE 2 is an enlarged sectional view of the window and frame of FIGURE 1, taken on line 22 of FIG- URE 1;

FIGURE 3 is a further enlarged fragmentary view of a portion of FIGURE 2;

FIGURE 4 is a sectional view of the glazing gasket used in the structure shown in FIGURE 3;

FIGURE 5 is a fragmentary view similar to FIGURE 3, showing a modification of the glazing gasket; and

FIGURE 6 is a fragmentary view similar to FIGURE 3, showing another modification of the glazing gasket.

The window unit 10 depicted in FIGURE 1 comprises a molded concrete frame 12, a glazing gasket 14, and a pane of glass 16. As shown in FIGURE 2, and more clearly in FIGURE 3, frame 12 is provided with an inwardly directed annular groove 13 into which glazing gasket 14 is sealingly engaged.

Glazing gasket 14 is an elongated strip, usually made of natural or synthetic rubber or other elastomeric material, which extends all the way around the inside perimeter of the frame 12, being sealingly engaged in the annular groove 18 throughout this inside perimeter.

As best seen in FIGURE 4, the glazing gasket has a body portion 19 to which is attached a longitudinally extending tongue 20. A longitudinally extending groove 22 is formed in the side of the body opposite the tongue side, the groove being formed by wing elements 24, 26. The body is provided with a frame-engaging face 28 on the iifice tongue side, this face preferably extending substantially perpendicular to the tongue, or at an acute angle relative thereto. Tongue 20 is provided with ridges 30 which are preferably backwardly directed teeth or barbs which are directed toward the body of the glazing gasket so as to allow the tongue to be readily inserted into the groove 18 in the frame but resist removal of the tongue from the groove. The ridges 30 function as sealing elements to provide a fluid-tight seal of the tongue 20 in groove 18. It will be appreciated that the thickness of tongue 20 with the ridges 30 in their free position, is greater than the width of groove 18. Additional sealing is provided by lips 31 extending longitudinally along the edges of tongue 20, which engage the bottom of groove 18.

In the embodiment shown in FIGURES 3 and 4, frameengaging face 28 is provided with lips 32 along each edge and longitudinally extending ridges 3-4 intermediate the lips and the tongue. The lips 32 and ridges 34 are deformed upon insertion of the tongue 20 in the frame so as to provide sealing engagement of the face 28 therewith.

Wing elements 24 and 26 terminate at their edges most removed from the frame-engaging face in lips 38, 40, which form the entrance to groove 22. One laterial side of the body is provided with a longitudinally extending wedge recess 42 which is adapted to receive a wedge 44. Wedge 44 forces lip 38 into sealing engagement with the panel 16, the lip 40 similarly being held in sealing engagement with the other side of panel 16.

It will be apparent that the structure of this invention is assembled by inserting the tongue 20 of the glaz ing gasket into groove 18 far enough so that the lips 32 are in sealing engagement with the frame, followed by bending wing element 2 back and inserting the panel 16. The Wedge 44 is then inserted into groove 42 to retain lips 33 and 40 in positive sealing engagement with panel 16. The ridges 30 serve to retain lips 32 in sealing engagement with the frame.

Another embodiment of the invention, shown in FIG- URE 5, omits the ridges 34 on frame-engaging face 23 and the lips 31 on tongue 20, so that sealing between the frame and the glazing gasket is attained by means of the ridges 30 on tongue 20 and the lips 32 on frameengaging face 28.

In the embodiment shown in FIGURE 6, another form of tongue is used to retain the glazing gasket in sealing engagement with the frame. Tongue 50 has a somewhat trapezoidal shape, the small side of the trapezoid being adjacent frame-engaging face 52, and is hollow. Thus the tongue 50 may be compressed for insertion into a groove 54 in frame '56, and thereby achieve a sealing engagement. The groove shown in FIGURE 6 is a dovetail groove, which will function to pull frame-engaging face 52 and its sealing lips 58 into a sealing engagement with the frame. It is evident that when a dovetail is used, groove 54 and tongue 50 are proportioned so that lips 58 are held tightly against the frame.

It will be evident that the structure of this invention provides simple means for supporting glass or other building panels in molded concrete or other frames with out the use of additional intermediate metal framing elements, and that means are provided for insuring that wind and water do not leak around the panels. In a test of the structure of this invention, using panels approximately four feet Wide and eleven feet high, a wind as high as miles per hour was used to blow water simulating an average rainfall of 4.85 inches per hour against the structure of this invention. It was found that no water leaked around any of the glazing gaskets, and all glass panels remained firm in the frames.

Several embodiments of the invention have been shown and described herein. Many other modifications, however, will be apparent to those skilled in the art, therefore the invention is not limited to the specific embodiments disclosed, but only as defined by the following claims.
