STORM SASH CONSTRUCTION Filed May 19, 1964 2 Sheets-Sheet l /NVEN7'0A JOHN 14. 5A KER 4770/?NEY Jan. 18, 1966 J. A. BAKER STORM SASH CONSTRUCTION 2 Sheets-Sheet 2 Filed May 19, 1964 United States Patent 3,229,434 STORM SASH CONSTRUCTION John A. Baker, Des Moines, Iowa (Industrial Park, lylalden, M0.) Filed May 19, 1964, Ser. No. 368,514 10 Claims. (Cl. 52-408) This invention relates to improvements in what is commonly referred to as combination screen and storm windows and more particularly to the construction and mounting of the storm sash.

In the use of storm windows of the above class, the satisfactory elimination of drafts and frost penetration is a frequent problem and arises generally where metal to metal contact is present between storm window framing and the supporting frame structure to which it is attached, or where screws are used for securing the storm window sash structure which permits the infiltration of frost as is well known. Various forms of insulation strips have been employed in different ways but these, if sufliciently satisfactory, are generally quite expensive and very often have not adequately solved the problem.

Accordingly, one of the important objects contemplated by this invention is the provision of an improved storm sash framing or construction which includes a novel and efficient frost barrier protection not only between the storm window and its supporting structure, but also between the storm window and prime window, and which can be simply and easily mounted and removed without the use of any tools.

Another object herein is the provision of a storm sash framing for which no screws are needed in attaching the same so that no holes are required to be drilled which would create an access point for frost penetration.

A further important object is to provide a storm sash construction of the above class which includes a novel snap-in, snap-out locking means for securing the storm sash to its supporting structure.

Still another object herein is the provision of what I call a vinyl glazing strip which can be easily secured to or removed from the edge portions of the storm sash frame so that there is no metal to metal contact between such frame and its supporting structure.

To attain these objects and such further objects as may appear herein, or be hereinafter pointed out, reference is made to the accompanying drawings forming a part hereof, in which:

FIG. 1 is a front elevational view of my new storm sash shown mounted in a supporting frame structure,

FIG. 2 is an enlarged combined perspective and crosssectional view taken relative to the line 22 of FIG. 1,

FIG. 3 is a crosssectional view taken on the line 33 of FIG. 1,

FIG. 4 is a perspective exploded view of this new storm sash construction, and

FIG. 5 is a view similar to FIG. 2 but showing a modification thereof.

Referring to the drawings, the rectangular window frame structure designated generally by the numeral is what I shall refer to as the supporting frame for my new storm sash construction 12 shown in FIG. 4. Frame 10 may be of any desired construction and as preferably contemplated here is of aluminum. It is adapted to be mounted in an opening of a building wall (not shown) in a well-known manner and includes peripheral flanges 14 on all sides for overlapping attachment to the wall at the outer side thereof. Frame 10 will also include channels such as 16 and 18 about the top, bottom and side edges which frame the central opening 20 in which there is generally slidably mounted the framed glass panes (not shown) known as the prime window. No invention is 3,229,434 Patented Jan. 18, 1-966 claimed in frame 10 per se and the prime windows referred to are not shown since they form no part of this invention and are mentioned merely to point out the type of window with which the storm sash 12 is used. Such windows as generally characterized above are also known as combination windows since it is a common practice to provide some form of storm window therewith and for this purpose, frame 10 also includes on its outer side relative to channels 16 and 18 a suitable flange or shoulder 22.

For my purposes, as will later appear, I have provided flange 22 with an upstanding sidewall 24 as best seen in FIG. 1 that extends along both

sides

26 and 28 and the bottom 30 of frame 10 and at

sides

26 and 28 terminates at the top in a lip or shoulder 32 which is spaced above flange 22 and is undercut or notched 34 throughout its length. Between lips 32 across the inner side of frame 10 at top 36 there is secured a metal weather strip 38 that extends on a plane intermediate the plane of lip 32 (FIG. 3) and the plane of flange 22 represented across the inner side of top 36 by the thin head or shoulder 40 (FIG. 3). Across the bottom 30 between shoulders 32 and on the same plane as strip 38 is the head 41.

With reference now more particularly to FIGS. 2 and 4, the storm sash 12 includes a rectangular frame 42 formed with suitable window track means 44 and 46 defining a central opening 48. It will be understood that framed panes (not shown) will be slidable in

tracks

44 and 46 in a Well-known manner to serve as a storm Window closure for such opening. Such panes, as well as those forming the prime windows as mentioned above, may be of any desired design and are not shown since they are immaterial to this invention which relates only to the construction of sash 12 as it is concerned with mounting to the supporting frame 10. In this regard, frame 42 is provided with the peripheral flange on all four sides identified by the numeral 50 at the top, 52 and 54 at opposed sides and 56 at the bottom. The outer dimension of these flanges is such that they will rest on shoulder 22 of frame 19 within the confines of the sidewall 24 on the several sides of frame 10.

Thus far described it will be appreciated that there is a metal to metal contact between

flanges

50, 52, 54 and 56 and shoulder 22 and while such metal to metal contact is a common arrangement in combination windows, I have found that the elimination of such metal to metal contact provides a better frost barrier protection. Accordingly, I have used elongated slotted

vinyl glazing strips

58, 60, 62 and 64 for frictional slip-on attachment to the edge portion of the

respective flanges

50, 52, 54 and 56.

Strips

60 and 62 are also formed with the respective depending longitudinal lips 66 and 68 (FIGURE 4) along their closed side which rest on shoulder 22 whereby the flanges of frame 42 are supported in spaced relationship above shoulders 22 and correspondingly spaces sash 12 away from channel 18 in frame 10 as best seen in FIG. 2. By this arrangement, a window (not shown) which will be slidable in channel 18 as mentioned may be more easily removed from the inner side of frame 10 because of the spacing provided by lips 66 and 68.

With

strips

58, 60, 62 and 64 mounted as described, sash 12 is placed on frame 10 as seen in FIG. 1 where the upper glazing strip 58 is wedged beneath the weather strip 38 and the lower glazing strip 64 will tightly abut the inner side of the narrow head 41. Frame 42 is then locked to frame 10 by one of the novel aspects of this invention which includes the two like elongated resilient vinyl or metal V-shaped locking strips 70. By virtue of their V shape, strips 70 define an upper edge 72, and a lower edge 74 that is provided with the outwardly turned lip 76. Locking strips 70 are placed in juxtaposition on the

respective strips

60 and 62 so that the open V end is toward the sidewall 24 and lip 74 is wedged between the closed end of

strips

60 and 62 as can be clearly seen in FIG. 2. In this position the normal spread between

edges

72 and 74 of strip 70 is such that edge 72 can be pressed downwardly below lip 32 on the sidewall 24 where it will, because of its resiliency, snap into engagement in notch 34 and thereby adequately secure frame 42 to frame 10. This, as can be appreciated, requires no screw holes where frost might penetrate and also requires no tools either for mounting or for removal. At the same time, the locking strips 70 add further insulating protection as can be seen in the drawings.

With reference now to FIG. 5, I have shown a variation for mounting sash 12 to frame which eliminates the

strips

60 and 62, and which may eliminate

strips

58 and 64, if desired, but retains the locking strip similar to strip 70 only in larger proportions for obvious reasons and which has like numerals primed relative to the strip 70. This arrangement, while generally satisfactory, permits a metal to metal contact of

frames

42 and 10 that is maintained reasonably tight by strips 7t) although the full stripping of frame 42 as described above is preferable and believed to be generally more eflicient for purposes of insulation. I

It is submitted that the invention shown and described is aptly suited to achieve the purposes intended and is characterized by a combination of highly useful and mutually cooperating elements that combine their respective and proportionate functions in accomplishing the objects sought to be obtained.

It will be understood that the phraseology employed herein is for the purpose of description and not for limitation and that modifications and changes in the construction and arrangement of this invention can be made within the scope of what is claimed, without departing from the spirit and purpose thereof. It is thus intended to cover by the claims, any modified forms of structure or mechanical equivalents which may be reasonably included within their scope.
