WINDOW FASTENER CONSTRUCTION Filed Sept. 5, 1956 HMEQ 12 Have,

IN VEN TOR.

United States Patent The present invention relates generally to window frame fastening arrangements, and relates more particularly to such fastening arrangements wherein means are carried by a portion of the window frames or surrounding structure for permanently securing the frames in position in a wall section or the like. i i

When installing window frames, and particularly when fitting prefabricated types of window frames, serious problems have long existed relative to the methods for permanently securing these frames in place. It has been one usual practice to construct the window frames from individual components and to secure each of these cornponents to a wall section as the frame is built up. Such a construction presentsdittle difficulty froma securing standpoint, but is time consuming and expensive. Through use of prefabricated frame sections that are adapted for insertion into opposite sides ofan opening in a wall section, considerable time is saved in the installation thereof. However, in order to secure these prefabricated frames permanently in position in awall opening, it has [heretofore been necessary to employ fastening means, such as nails, screws and the like, that not only required considerable time for the installation, but also detracted from the uninterrupted and smooth exterior appearance of the frame garnish. I I V V j Several attempts have been made heretofore in efforts to solve the fastening problems associated with the installation of prefabricated window frames. These attempts have taken the form of complex mechanical structures, many of whichrequired the use-of specially constructed openings in wall sections. The many components used in prior structures have necessarily made these structures expensive and have increased the possibilities that one or more of the components would be inoperative or poorly constructed. With increasing costs of construction labor,

duced to a minimum commensurate with quality construction and reliable fastening means. I

It is therefore one important object of the present invention to provide an improved fastening means for window frames. g. a

It is 'a further object of the invention to provide a novel window frame fastening arrangement wherein extremely simple, reliable, efficient, and inexpensive fastening means are employed. I

Another object of the invention is to provide improved means for securing a window frame to the wall forming an opening for a window.

A still further object of the invention is to provide a universal window frame fastening arrangement having means for continuously biasing fastening elements into tight engagement with the wall forming the window opening. 7

Other and further important objects of the invention will become apparent from the disclosures in the following detailed specification, appended claims, andaccompanying drawing, wherein:

Figure l is a perspective view showing a typical window frame structure foremploying the fastening arrangement of this invention;

Fig. 2 is an enlarged fragmentary sectional view showing details of the present fastening arrangement, takensubstantially as indicated by the line 22 of Fig. l; and

Fig. 3 is a detail perspective view showing the fastenin clip employed with the present invention.

- With reference to the drawing, Fig. 1 illustrates a type of window that may include the features of the present invention in regard to the fastening arrangement therefor. As shown in Fig.1, a generally rectangular window frame 10 is adapted for disposition in a suitable, substantially rectangular opening 11 in a wall section 12. The frame 10 has a window 13 hinged thereto as at 14, with the window 13 having the usual binding frame 15 ther'eabout. A moisture-deflecting hood 16 may also be provided over the upper edge of the window and secured to an outer surface 17 of the wall section 12. 0

With reference primarily to Fig. 2, the frame 10 may be made from any suitable material, as by extruding aluminum, or the like, and includes an outer. flange portion 18 and an inner flange portion 20 that are integrally interconnected by means of a sill portion 21. The flange portions 18 and 20 are disposed in opposite directions from the sill portion 21, with the flange portion 18 being adapted to overlie the outer surface 17 of the wall section 12. A sealing strip" 22 is positioned between the surface 17 and an innersurface of the flange portion 18, to provide a resilient urging of the flange portion away from the surface 17, for a purpose that will be more fully described hereinafter I As further shown in Fig. 2, a plurality of clips 25 are secured to an outer surface 26 of the sill portion of the frame 10. The clips 25 are made from any suitable resilient material and are positioned at longitudinally spaced intervals, and each is secured to the sill portion 21 by means of a rivet 27, or the like,,that extends through a hole 28 in each of the clips into a hole in the sill portion. Each of the clips 25 isbent outwardly as at 30 to provide a freerend portion thereof that forms an acute angle relative to the surface 26 of the sill' portion '21. The free edge of each clip portion 30 is indicated at and is cut off at substantially a right angle" to the portion 30. Clips are similarly arranged on all sides of the frame member. I Toassernble the present window frame arrangement 1n the opening 11, it is only necessary to insert the side 50 of the frame 10, having the flange portion 20, intothe it is extremely important that installation time be re- 1' opening For this purpose, the opening 11' is made sllghtly larger than the outer dimensions of the frame portions 30: of the clips 25 normally have their outer-edges disposed lbeyond the dimensions of the'opening 11 'in the wall section 12. Thus, when the frame 101's inserted into the opening 11, the portions 30 of theclips 25"a re deformed inwardly toward the surface 26 of the sill portion and bite into the material of the wall section 12 or into the material of any framing structure built to define the opening 11. The resilient force of the clips 25 is such as to cause the edges 31 to be slightly embedded in the material of'thewall section and to deform the same, thus providing a secure retaining means for the frame member and normally preventing removal thereof from the opening 11. The force of the sealing strip 22, when under compression, serves to bias the edges 31 of the several clips into permanent continuous tight deformable engagement with the material of the wall section. This window retaining arrangement is particularly elfective when the surface of the wall engaged by the clips 25 is Ice Patented June 24, 1958 3, formed by wood or other deformable material adapted to yield to the bite of the, clips to provide a deformable engagement therewith and to retain the clips in position.

Thus, there has been provided a reliable, eflicient, and

extremely simple method and apparatus for fastening a window'frame arrangement into a building structure and for providing a permanent installation of the frame. Through use of the present arrangement, it is therefore possible to install window frames in a minimum amount of time and thereby to enable reduced labor costs.

, Although only one particular form of this invention has been specifically described herein in detail, it will be obvious that the invention is not limited thereto, but is capable of a wide variety of mechanical embodiments. Accordinglypvarious changes which will now suggest themselvesto those skilled in the art may be made in the material, form, details of construction, and arrangement of the elements without departing from the scope of the invention as defined by the appended claims.
