Description
United States Patent WINDOW SEALING STRIP Robert 0. Morgann and Russell J. Bush, Dayton, Ohio, assignors to General Motors Corporation, Detroit, Mich., a corporation of Delaware Application December 5, 1950, Serial No. 199,318
6 Claims. (Cl. 189-65) This invention relates to weather-sealing strips for casement windows, or other windows wherein the window sash moves laterally against a stationary window frame to close the window opening.
An object of this invention is to provide a very economically made yet highly efllcient non-metallic sealing strip for such windows.
Another object is to provide such a sealing strip which can be readily and quickly assembled upon the window sash, or removed therefrom for replacement or other purposes.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein a preferred embodiment of the present invention is clearly shown.
In the drawings:
Fig. 1 shows a front elevation of a casement window having a weather-sealing strip applied thereto according to this invention.
Fig. 2 is a section taken on line 2-2 of Fig. 1 on an enlarged scale.
Fig. 3 is a section taken on line 3-3 of Fig. 1 on an enlarged scale.
Fig. 4 is a perspective detail view illustrating a means for fastening the end of the sealing strip to the sash frame.
Similar reference characters refer to similar parts throughout the several views.
Reference numeral designates the steel sash frame which extends around the periphery of the movable window sash. Sash frame 10 has an outwardly projecting outside peripheral flange 11, an offset inner flange 12 extending continuously around its inner periphery, and a continuous relatively short outwardly projecting flange or head 13 at the interior edge 14 of frame 10. Bead 13 thus forms a shallow channel 15 extending continuously around the outer periphery of frame 10.
The movable sash 10 is illustrated in the drawings as closed by being moved to the right (as viewed in Figs. 2 and 3) against a stationary steel frame rigidly fixed in place to the side wall 21 of a building in any suitable well-known manner. Frame 20 has an inwardly projecting interior flange 22 and an offset exterior flange 23. Figs. 2 and 3 illustrate how the section of sash frame 10 overlaps and interfits with the section of the stationary window frame 20 when the movable window sash is in window-closing position.
Now according to this invention a flexible flat-section band 30 of elastic resilient rubber or rubber-like material is applied to the steel sash frame 10 so that it fits flatwise snugly within the shallow channel 15 adjacent the small outwardly projecting head 13. Band 30 is of uniform cross section and has an integral angularly projecting and hence easily flexed sealing flange 31 which extends around head 13 and projects laterally beyond the interior edge 14 of sash frame 10 so that the edge of said flange 31 is pressed into sealing contact with the flat surface of flange 22 of stationary frame 20 when sash frame 10 is in closed position, as shown in Figs. 2 and 3.
In the perferred form, the flexible elastic band 30 is made in one piece and is retained in place under tension by stretching same around the four sides of the sash frame 10 and fastening only the two ends thereof to frame 10. Fig. 4 shows the preferred form of a bend wire hook 35 which may be used to fasten each end of band 30 to frame 10. Hook 35 is securely fastened to band 30 by forcing the two angularly bent free ends 36 of the Wire thru the elastic body of band 30, as clearly shown in Fig. 4. The bent end 37 of hook 35 is preferably slightly collapsible (due to the springiness of the folded wire) and may be readily forced thru an aperture 38 in the bottom of the shallow channel 15 in frame 10, as shown in Fig. 3.
Now to properly assemble the elastic flexible band 30 to the sash frame 10, one end of band 30 is first attached in place by its hook 35 as above described and then band 30 is simply stretched around frame 10 to lie within its peripheral channel 15 and the hook 35 at the other end of band 30 is hooked into its aperture 38 in frame 10. Thus band 30 is retained in place under such tension as will cause it to lie snugly within its shallow channel 15 at all times and yet be sufiiciently yieldably retained as not to restrict any required flexing of the sealing flange 31. When band 30 is thus held under even tension from end to end thereof it will always be urged to return to its normal snug fit within channel 15 if by any cause it be accidently dislocated.
The drawings illustrate common cross sections of steel sash frames and stationary frames used in present day casement windows. The flexible elastic sealing strip 30 of this invention may be very simply and quickly applied to such windows as above described. The strip 30 may be made in continuous length and cut to the desired length on the job when attaching same. Also the Wire hooks 35 can be very quickly and simply attached to the strip ends by the workman on the job by simply pressing the wire ends thru the strip at the desired location.
While the embodiment of the present invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted.
