United States Patent 2,909,812 v SEAL FOR WINDOW HAVING AIR CONDITIONER Abe Pritzert, Philadelphia, Pa. Application September 16, 1958, Serial No. 761,379

2 Claims. (Cl. 20-52.4)

This invention relates to an attachment for a window and more particularly to an attachment to seal the open space between the sashes of a double hung window when an air conditioner or some other comparatively bulky device occupies the lower part of the Window.

An object of the invention is to provide a window attachment which is easy to handle for both installation and removal, the attachment constituting an effective weather seal between the upper frame member of the lower sash and the glass of the upper sash of a double hung window when the lower part of the window frame has an air conditioner supported therein.

It has become customary for windows having air conditioners, to seal the open space between the sashes by nailing, tacking or otherwise rigidly securing a sealing member of one type or another between the windows. It then becomes impossible to clean the outer surface of the inside sash and the inner surface of the outside sash glasses to completion. This invention solves the problem that is presented by the now popular window air conditioner, enabling the windows to be more easily manipulated so that the surfaces of the window glasses may be cleaned. This is accomplished by an attachment that is separably connected at the upper part of the lower sash by a unique clamp or a pair of clamps at the ends of a strip that occupies the space under discussion.

A more specific object of the invention is to facilitate window cleaning and have a very effective weather seal between window sashes of air conditioner supporting windows, by using a strip having a pad thereon with the pad adapted to contact the glass of the outside sash and the upper frame member of the inside sash, together with very easily operated clamps at the ends of the strip which 2,909,812 Patented Oct. 27, 1959 on, together with a window sill 18. Air conditioner 20 diagrammatically represents any manufacturers make of air conditioner or other appliance which may be disposed in the window opening. The window has two conventional sashes 22 and 24, each provided with a window pane or glass 26 and 28 respectively.

Attachment 30 is composed of a flat strip 32, preferably of light weight metal, for instance aluminum alloy, to gether with a flexible pad 34 adhered to the lower surface of the strip 32. The pad may be made of felt, rubber or some other flexible material capable of functioning as an effective weather seal. The connection between strip 32 and pad 34 may be made in a number of ways, for instance it may be cemented in place.

The two ends of strip 32 are made in an identical manner. Each has a forwardly opening notch or recess 38 to fit around the sides of the frame 16 of the upper sash 24. An edge portion 42 of pad 34 protrudes laterally outwardly from the edge 44 of strip 32, and the part of pad 34 adjacent to notch 38 also has a notch 46 therein. The two notches, then, accept the side frame members of the upper sash 24 when the attachment 30 is applied to the window.

engage the confronting sides of a conventional window frame, firmly gripping them and keeping the window in place. However, the attachment is easily removed inasmuch as one or both of the clamps is made adjustable between open and window frame side engaging positions.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout and in which:

Figure l is a front perspective view of a window having an air conditioner therein and an attachment between the sashes of the window.

Figure 2 is an enlarged sectional view taken on the line 22 of Figure 1.

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Figure 4 is a fragmentary perspective view of one end of the attachment.

Figure 5 is a fragmentary perspective view of a modified form of the attachment.

In the accompanying drawings there is a conventional window 10 having sides 12 and 14 of the frame 16 there- There are means for fastening the attachment 30 in place as shown in Figure 1. These means consist of two identical clamps 50 and 52 respectively, although it is within the purview of the invention to use a clamp only on one end of the attachment, should this be desirable. Typical clamp 50 is made of a fiat spring 54 having two'upturned ends or parts 56 and 58. The part 58 is a finger grip, and part 56 is adapted to engage the surface of side 14 of the window frame in order to grip against it and hold attachment 30 firmly in place. Spring 54 has a slot 60 between its ends, through which thumb screw 62 is passed. The thumb screw is also passed through a washer 64 and engaged in a threaded opening 66 near the end of strip 32. Accordingly, spring 54 may be tightened in place by thumb screw 60 or permitted to be adjusted in a direction parallel to the longitudinal axis of the flat, elongate strip 32. When adjusted outwardly of strip 32, it is in the window frame side gripping position. When adjusted inwardly, the attachment 30 may be easily lifted from its place on the upper member 23 of the lower sash 22.

In use, strip 32 is placed with its pad 34 flush against the upper surface of the frame member 23. The clamps 50 and 52 are adjusted so that they have their outer ends frictionally gripped against the confronting surfaces of the sides 12 and 14 of the window frame. With the edge portion 42 of the pad gripped firmly against the glass 28 of glazed sash 24, and the notches 46 in the pad firmly contacting the sides of the upper sash 24, an eifective weather seal is produced. Yet, the attachment 30 is very easily removed when it is desired to clean the windows, by making looseeither clamp 50 or clamp 52 and lifting the attachment from its place on the upper part of lower sash 22.

Reference is now made to Figure 5. This embodiment of the invention differs from the embodiment in Figure 1 by only one particular. Attachment 30a has pad 34a made with one or more slits 68 so that the parting strips 70 of the multi-light upper sash 24a are accepted in the pad. Any number of slits 68 may be used depending on whether the upper sash has one or more parting strips.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and 3 equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. An attachment for a window having a window frame provided with a sill, an upper glazed sash, a lower glazed sash in the open position to receive an air conditioner on the sill and beneath the lower member of the lower sash frame, said attachment comprising a strip disposed between the sides of the window frame and above the upper member of the lower sash frame, means separably fastening said strip between said window frame sides, said fastening means including a fiat spring at one end of said strip, and a flexible pad attached to said strip and having a. lower surface in contact with said lower sash upper member and having an edge portion protruding outwardly beyond the adjacent edge of said strip and engaging the glass in said upper sash, and said pad having notches in the ends thereof to accept the side members of the frame of the upper sash.

2. The attachment of claim 1 wherein said pad which projects beyond one edge of said strip has at least one slit to accept a parting strip in the upper sash.
