United States Patent 3,086,258 WEATHER STRIIPING James D. Fuller, 3635 16th Ave. W., Seattle, Wash. Filed Mar. 31, 1961, Ser. No'. 99,788 1 Claim. (Cl. 20--42) This invention relates to weather stripping and an improved method of its -application about hinged window sash and .other similarly applied closures, as a means for sealing the joint between the closure `and its :frame .against wind and `other inclemencies of weather.

More specifically stated, the present invention pertains to the weather stripping of wooden frames that .are litted with easement, hopper or awning types of windows or other similar closures mounted by foldable friction hinges.

In the past it has Ibeen quite diicult to satisfactorily weather strip windows which are equipped with those types of foldable hinges which are gained into .the sash and which comprise a plurality of pivotally joined links designed to support the window sash in different positions of open .adjustment and which links are adapted to fold into side by side relationship with the closing of the Window; this joint sealing diiticulty being lespecially diiiicult when metal weather stripping is employed for that purpose in association with such hinges.

In view of this above mentioned difticulty and for various other reasons, it has fbeen the principal object of the present invention to provide Weather stripping that is formed by the use, in combination, of neoprene rubber strips or like conformative material and lwooden strips; the `latter being so shaped as to seat the neoprene strips therein Aand are applied continuously about the sash opening except where the hinges occur to coact with the neoprene strips upon closing the Window to Iseal the joint between frame Vand sash -to its full perimeter including the joint across the lfolded hinges so .that the usual -diiculties of Weather stripping across them are eliminated.

Further objects of the present invention reside in the various details of construction of parts and in their coacting relationship in use, as will hereinafter be fully described.

In accomplishing the above mentioned .and .other objects of this invention, I have provided the improved details of strip construction, the preferred forms of which 'are illustrated in the 'accompanying drawings, Iwherein:

FIG. l, FIG. 2 and FIG. 3, respectively, are outside elevational views of a easement Window; an awning type window and la hopper type window, each of which has its sash pivotally mounted in its trame by a pair of fol'dable friction hinges.

FIG. 4 is an enlarged cross-sectional View, taken on line 4 4 in FIG. 1.

FIG. 5 is an enlarged cross-sectional View taken on line 5 5 in FIG. 1.

FIG. 6 is an enlarged cross-sectional view taken vertically through the sill portion of a window equipped with an awning type sash, on line 6--6 in FIG. 3.

FIG. 7 is a cross-sectional detail of the sealing joint taken on line 77 of the hopper type window ot FIG. 2,.

FIG. 8 is a cross-sectional view of one of the wooden strips used in conjunction with the neoprene rubber strips for weather stripping.

FIG. 9 is a sectional detail illustrating a sash yas mounted by a friction hinge of the type previously referred to -for the mounting of the sashes of the present invention.

Referring more in detail to the drawings:

FIGS. 1, Zand 3 have been sho-Wn only for explanatory purposes; to illustrate different sash mountings, and in each of which the sash is mounted Afor swinging `adjustice ment between fully closed and open positions by lfriction hinges ofthe type shown in FIG. 7.

In FIG. 4, 10 `designates the horizontal head jamb of a wooden window frame las mounted in a wall opening of a Wooden building of typical construction and 11 designates the corresponding top member of -a window sash v12 that is mounted inthe frame as a closure for the frame opening. The window of this vieW of the drawing is, by reason of the particular manner of its hinged mounting for lateral outward opening, designated -or known as a easement window. The sash 12. of this view, and also Ithose similarly designated in FIGS'. 2 and 3, is mounted at opposite sides by hinges 15 of the kind shown in FIG. 7; these being gained into the sash, in the manner illustrated at 16 in FIG. 5.

The weather stripping of this invention is so applied as to provide a tightly sealed joint between trame and sash to the full perimeter of the sash when it is closed. It comprises wooden strips 20 `and neoprene rubber strips 21. The Wooden strips 20 are rectangular in cross-section and are applied entirely about the window opening except where the folded hinge is located. They vare seated and secured, as best shown in FIG. 4, in the right angle corner as formed by the frame j ambs and window stop `as applied thereto; the strips 20 being set ilatwise against the janrbs and all 4are formed lengthwise thereof, along their outer corners with concave seats, as at 25, against which .the neoprene rubber strips, as applied to the sash, engage in joint sealing Contact.

The neoprene or rubber strips are applied to the sash in the manner best understood by reference to FIGS. 4, 5 and 6. Preferably these strips are of tubular formation, about 1A in diameter and formed to their full lengths along one edge with a thin projecting flange 26.

The presently preferred manner [of applying the neoprene rubber strips to a sash requires the rabbeting of the inside corner edges of the sash entirely about its periphery, as shown at 30; the rabbeted channel 30 being to such depth and 'width as to receive the wooden strips therein as in FIG. 4 when the sash is closed. The sash also is formed with a continuous channel 32 iiush with the outer Wall surface of the rabbeted channel 3l); this channel 32 being of such Width and depth as to receive the ilange 26 of the neoprene strip therein, for functional securement of the strip for joint sealing. With the wo-oden and neoprene strips so applied, with the closing of the sash, the tubular neoprene strips are compressed tirmly against the concaved seats 25 as formed in the wooden strips, and also are somewhat flattened against the folded links of the hinges as in FIG. 5, thus to most eiectively and eiiiciently seal the joint entirely about the window.

'It is preferred that the ilanges Z6 of the neoprene strips be pressed into their channels after having a suitable glue or adhesive applied thereto so as to prevent any possible displacement of the neoprene strip incident to normal use of the window.

IIt is to be understood that details of construction .of the parts as used in combination herein may be altered or changed to suit special forms of parts of sash and frame members to conform to certain requirements. :For example, the wooden strip 2t), as applied across and to the window sill in FIG. 6 slightly diters from the strip as shown in FIG. 4 but performs the same function in the same way. It is also understood that the specific form or type of hinge employed may be somewhat varied without departing from the spirit of the invention so long as the neoprene strip effects the same joint sealing function.

iFIG. 7 illustrates a form of wooden strip 20x that is applied across the sill of the hopper type of sash to accommodate the particular downward closing movement of the lower rail of the sash. Note that this particular strip is formed with an upwardly projecting bead 26y and a longitudinal seat Zlz against which the strip 21 engages as the window closes.

It is also anticipated that joint sealing strips of conformative material other than neoprene might be successfully applied and secured in place by other manner of means. However, I have found that by using 50 Shore neoprene with tube walls 1,@2 thick a most satisfactory seal is obtained. Neoprene rubber is an excellent insulating material, it does not frost and will not get hard in a temperature of 40 below zero. Such weather stripping is especially desirable for use in cold countries such as Alaska.

What I claim as new is:

A window structure comprising a frame providing an opening, a sash mounted in the said opening for adjustment between open and closed positions, stop strips applied to the frame within the opening thereof against which said sash is adapted to close; said sash being formed entirely about its peripheral edge with a continuous rabbeted channel that receives said stop strips therein upon the closing of the sash and which provides a peripheral shoulder about the sash in opposed relationship to said stop strips, said stop strips providing hinge spaces therein at opposite sides of the sash opening, a pair of friction hinges gained into the sash at opposite sides thereof in positions to be received within the open spaces in the stop strips upon closing the sash, and a compressible strip of conformative weather stripping material fixed to and extending entirely about the sash in position for its coinpression between said peripheral shoulder at the outside and said stop strips and hinges at the inside upon the closing of the sash thus to seal the joint entirely about the sash.
