Application March 19, 1958, Serial No. 722,490

11 Claims. (Cl. 20-55) This invention relates to the art of storm windows as applied to buildings and the like, and more especially to a novel conversion structure employing a simple and inexpensive modiicatiou of a conventional wooden-frame storm window.

The problems involved in the installation, removal and storage of the conventional wooden-frame storm sash and screens are so well known as to require little discussion here. metal-frame so-called self-storing storm windows and screens, which, experience has shown, are too costly and seldom afford the advantages claimed for them. As a departure from that approach, the present invention offers a novel solution which features removal of the pane from a single-pane storm window o-r just one pane from a conventional multi-paned wooden storm window and the modiiication of the pane opening by the provision of a simple and inexpensive light-weight secondary frame which interchangeably receives a glass panel insert or a screen panel insert. It is a further object of the invention to so modify the storm window that the pane removed in the first instance may be framed and used as the glass insert. A still further object resides in the provision of the secondary frame in such manner that the original window rabbet remains intact and is concealed by the secondary frame. The invention further features a construction and combination of parts and materials such that the average individual can easily and economically convert his own storm windows to the combination type.

The foregoing and other important objects and desirable features inherent in and encompassed by the invention will become apparent as two preferred embodiments of the invention are disclosed, by way of examples, in the ensuing specification and accompanying sheet of drawings, the figures of which are described below.

Figure l is a perspective as seen from the interior or house side of one form of converted window.

Figure 2 is a vertical section of the Figure l structure, on an enlarged scale, partly in phantom and with portions omitted to permit the larger scale.

Figure 3 is an enlarged fragmentary perspective of a corner portion of the Figure l structure.

Also known are the many types of Figure 4 is a perspective of a modified form of structure as seen from the exterior of the building.

Figure 5 is an enlarged vertical section of the Figure 4 structure.

Figure 6 is a fragmentary perspective, partly in section, of a corner portion of the Figure 4 structure.

The numeral 10 in all figures designates as a whole a typical wooden-framed double-paned storm window having side frame members 12, top and bottom rails or

members

14 and 16 and an intermediate rail or member 18. These frame members define the conventional upper and

lower pane openings

20 and 22, rabbeted at 24 and 26 respectively to carry upper and lower panes, the upper one of which appears at 2S and the lower one of which has been removed according to the invention to leave the lower rectangular opening 22 as bordered by the rabbeted

frame members

12, 16 and 18. When the lower pane is removed, it is preferably saved and used as the pane or glass panel 30 in a panel frame 32 (Figures l, 2 and 3) which may be inexpensively constructed of commercially available sections such as aluminum extensions; although, this is by no means a limitation on the invention. It will be seen, especially from Figure l, that the pane 30 has the same dimensions as the rabbet 26 from which it has been removed. This feature provides a substantial saving in cost when measured over a large number of converted windows.

In Figures l, 2, and 3, the panel frame 32 is mounted in place, generally congruent with the lower opening 22,

via a secondary frame 34, here made up of four elongated channel members 36 respectively fitting the four sides of the opening 22, and each channel has a bight or web portion 38 and inner and

outer leg portions

40 and 42 respectively. Each channel may, if desired, be made of two parts of light sheet metal or other suitable material, joined as at 44 to provide a measure of adjustability if necessary to vary the spacing between the

legs

40 and 42 to accommodate window frame parts of different thicknesses. After proper adjustment, the joint may be rigiditied, as by compression and/or cementing. Normally, however, this dimension will be found to be standard. As seen, the legs 4t) and 42 respectively overlie the inner and

outer faces

46 and 48 of the associated window frame member, and the bight portion of each channel overlies and conceals the associated rabbet 26 as well as the associated interior molding configuration 50. Hence, the frame members of the window need not be cut away, illed in with strips or in any other way modiiied, thus lending to the extreme simplicity of the structure. Suitable fasteners, such as wood screws 52, may be used to secure the secondary frame 34 in place. Additional or alternate fasteners may be used through the legs 40 and/ or 42 if desired.

As best shown in Figures l and 3, each lower corner of the panel frame 32 has a laterally outwardly projecting pivot or pintle 54, and these are horizontally coaxial to be received by hooks 56 screwed into the window frame, thus affording a fulcrum parallel to the lower frame member 16 and about which the panel frame may be swung toward the window frame when installed and away from the window frame when removed. When in place, the panel frame is secured by turn members 58, which may be hooks screwed into the wooden window frame.

A peripheral gasket 60, of rub-ber or other suitable material, is interposed between the front or outer marginal face of the panel frarne 32 and the back or interior marginal face of the secondary frame 34 as provided by the channel inner legs 40. This gasket is preferably cemented to the secondary frame 34 so that it is in place for use with a similar panel frame bearing a screen. In this respect the term panel frame is used generically to include glass, screen or other material, but in the sense that glass is referred to specifically, emphasis is placed on the fact that the pane removed from the lower opening 22 of the window can be used in the panel frame 32. Also, frame sections suitable for the construction of screens by home owners are commercially available.

It will be clear from the above that the storm window lil, once converted, can remain in place, as in association with conventional double-hung sash shown in phantom at 62, and all that need be done is the seasonal interchange of glass and screen panels such as 32, which are obviously easier to handle than the entire storm window, besides which the panel changes can be effected interiorly.

In the modified construction shown in Figures 4, 5 and 1- 6, the numerals previously applied to the basic components of the storm window llil are again ernployedpand therefore the window itself need not be re-described. In this case, the secondary frame, designated as a whole by the numeral 64, is of la somewhat diierent type, but, like the frame 32, is made up of a plurality of channel members, each of which has a bight 66 and inner and .

outer legs

68 and 70 related to the rabbet`26 etc. exactly `like the channels of the frame 32. Retention of the secondary frame 64 may be achieved as by wood screws 72.

In this frame, the top and side members may be identical, each having a bead 74 against which the panel frame 76 abuts as it is swung forwardly about a lower horizontal fulcrum established by the combination of the lower portions of the side member beads 74 and a bead 78 on the lower frame member which isset back the thickness of the panel frame. The zones of meeting of the ends of. the bead 7S and .the lower ends of the side beads 74 provide horizontally alined pockets 8i) (Figure 6) which may be said to kconstitute opposite ends of a transverse groove into which and from which the lower edge of the panel frame is downwardly removable, respectively.

Since the secondary frame 64 mounts the panel frame 76 within an area smaller than that defined by the original window opening 22, the pane removed from the lower opening must be cut down, shown here at 30A, but nevertheless the savings in cost is still effected. In other respects, the features of the conversion struct-ure parallel those of the structure of Figures 1-3. Suitable upper releasable or removable retainers, such as screws, are provided at 82 for holding the panel frame 76 in place.

In the description of the Figures l3 structure, mounting and dismounting of the sto-rm window (or screen) panel has been covered in terms of swinging the panel about the fulcrum established at 54-56. An alternate method of mounting is required in those installations in which the lower rail of the raised lower sash `would prevent complete swinging or pivoting. ln such case, the mounting is achieved by inserting the panel upwardly between the storm window proper and the upper sash and then swinging'the lower portion of the panel toward the storm window frame, then allowing it to descend until the pins S4 are received by the hooks 56.

A further feature of the invention enables partial opening of the panel for ventilation. ln that case, the hooks 58 in the top horizontal row are removed so that the panel can be slid upwardly, say, about four inches or so. in doing so, the use-r shifts the panel slightly toward himself to clear the hooks 5S next above the hooks 56 and then moves the panel flat against the storm window frame so that the pins 54 rest on these next higher hooks and said hooks are turned to place their legs upright and thus duplicate the function of the hooks 56 except that the panel is slightly raised. ln achieving this procedure, there will be found to be enough giveLin the gasket 6i) to permit the operation outlined.

The foregoing illustrates preferred embodiments of the invention as constructions achieving the objects set forth, the presently signicant ones of which have been outlined in detail. Other objects and features as well as variations in the structures disclosed will readily occur to those versed in the art, all without departure from the spirit and scope of the invention.
