United States Eat-eat 5 3,912,605 WINDOW Raymond J. Turk, 27186 Mallard Ava, Euclid 32, Ohio Filed Dec. 22, 1958, her. No. 782,141 7 Claims. (Cl. 160-91) This invention pertains to windows and more particularly to double pane windows.

It is the object of this invention to provide a novel and improved window assembly in a completely integrated unit which at the option of the user creates an insulating space of dead air mitigating the transmission of both cold and heat through the glazed areas of the window by radiation and/ or conduction.

Accordingly, one of the principal objects of the invention is to provide a novel and improved double paned insulating window unit which is simple and inexpensive, and which requires no special and delicate manufacturing and assembly techniques.

A further object of the invention is to provide a novel and improved double pane window assembly in which an inner sash and an outer sash are pivotally carried by a window frame to permit opening of the window for ventilation.

An additional object of the invention is to provide a novel and improved double pane window assembly made in accordance with the foregoing objects of the invention which will capitalize upon updrafts along the sides of the building to provide forced ventilation to a room. To achieve this object the inner and outer windows are each pivotally hinged to permit each such pivotal sash to be pivoted into the jamb space between the inner and outer sashes to open the window.

A related object of the invention is to provide a novel and improved connection bar which connects the openable inner and outer window sashes so that movement of one of the openable windows to a selected position will cause simultaneous and corresponding movement of the other window.

A related and more specialized object of the invention is to provide such connection bar in the form of a pivot bar pivotally carried by the frame and slidably connected to the movable sashes so that movement of one sash causes corresponding movement of the other.

A still further object of the invention is to provide a novel and improved double pane window assembly made in accordance with the foregoing features in which a filter screen is disposed transversely across the space between the inner and outer windows at the center mullion to filter pollen, dirt, and other air impurities out of air entering through the window when open.

A related object of the invention is to provide a novel and improved double pane window having such a filter screen wherein the filter screen is positioned substantially horizontally so that it does not in any way obstruct the visibility through the window.

Another and related object of the invention is to provide a novel and improved double pane window assembly which has inner and outer spaced window sashes carried by a frame, which sashes are removably carried in the frame to permit facile cleaning of the windows from the interior of the building.

. Yet another object of the invention is to provide a novel and improved double pane window assembly made in accordance with the foregoing objects which may be inserted as a unit in either a new building or as a replacement window in an older building being remodeled or reconditioned.

Another related object of the invention is to provide a novel and improved double pane window assembly in a completely integrated unit, having inside and outside 3,IZ,505 Patented Dec. 12, 1961 sash-carrying frames of metal construction which are joined by means of head, sill and jamb panels of variable and optional depth to fit any desired dimension.

Still another object of the invention is to provide a metal framed double pane window in which the head, sill and jamb panels can be made of a wide variety of materials and colors to provide panels which blend with and enhance the decoration of the structure.

Another object of the invention is to arrange the sashes of a completely integrated window unit by new and novel design in such a manner that when the window is in an open position it will facilitate the inflow of outside air into the structure but at the same time afford protection against the entry of rain and snow.

Another object of the invention is to arrange the sashes of a completely integrated window unit by new and novel design in such a manner that even in an open position security is provided against mischevious or unlawful entry or exit, and which resists ingress or egress by humans or animals, and which also resists the transmission of objects through the window.

An additional object of the invention is to provide a novel and improved double pane window made in accordance with all of the foregoing objectives which can be fabricated quickly and easily to any dimension desired from one group of parts which are suitable for most all sizes.

device on an enlarged scale with respect to FIGURE 1 as seen from a vertical plane of cross-section; and,

FIGURE 3 is a sectional view as seen from the plane indicated by the line 3-3 of FIGURE 2.

Referring to the drawings, a frame member is shown generally at ill. A frame 10 includes a central plate or jamb member 11, which extends around the window to form substantially the visible peripheral limit of an installed window. The frame 10 also includes inner and outer

horizontal anchor members

12, 13, which may be imbedded in the building masonry, or the like, to fix the frame in position. Inner and outer

vertical tie members

14, 15 are connected to the horizontal anchors. The vertical tie members carry vertical jamb connecting strips 17, 1'8 which in turn support vertical segments 19,-

of the jamb member 11, FIGURE 3.

Inner and outer horizontal insulating and connecting

strips

20, 21 are provided in the embodiment shown. The horizontal connecting strips form an insulating tie between the

anchor members

12, 13 and horizontal sections 22 of the jamb member 11. The connecting strips l7, l8 and 2t), 21 provide one of the advantages of the invention. The connecting strips are formedrof an insulating material such as plastic. This construction perrnits the frame members to be made of metal'such as aluminum without convection of heat to or from the interior of the building which is normally a disadvantage of metal casement windows. Thus, the strips 17, 18,

. 2th, 21 permit the formation of a metal window frame are carried in outer sash receiving portion of the frame 1%. Upper and lower inner

window sashes frames

26, 27 are carried in an inner sash receiving portion of the frame. In the disclosed arrangement, the outer upper sash frame 24 is fixed in position as by screws 28 which connect the upper sash frame 24 to the outer vertical tie members 14. The lower inner sash frame 21 is fixed in a similar fashion to the frame as by screws 29 which removably fix it to the inner vertical ties 14.

The outer sash frames 24, removably carry

framed window panes

36, 31 respectively. The

outer window panes

30, 31 are carried in

suitable pane frames

32, 33 which are preferably aluminum. The

outer window panes

30, 31 are disposed in a common vertical plane. The inner

sash frames

26, 27 have panes of

glass

35, 36 respectively. The

glass panes

35, 36 are, like the

panes

30, 31, carried in

pane frames

37, 38 which are preferably aluminum. The

panes

35, 36, are also disposed in a common vertical plane which is parallel to and spaced from the plane of the

panes

30, 31.

The window panes are all readily removable from the frames to facilitate cleaning. In the disclosed embodiment this is accomplished by providing clamps 34 to lock the

pane frames

32, 33, 37, 38 to the respective sash frames. In the disclosed arrangement, the pane frames and panes are identical to simplify construction proce dures and to simplify and facilitate repair and washing. It will be seen that repair and washing can be accomplished from the interior of the building without care and regard as to which pane goes in what location.

A pair of upper sash support brackets 41 are fixed to an upper part of the frame of the inner upper sash frame 26. The sash brackets 41 are apertured to receive removable pivot pins 43. The sash frame 26 is movable outwardly to an open position, shown in phantom in FIG- URE 1, by pivoting about the pins 43. Opening and closing movement of the sash 26 is facilitated by a handle 44 which is fixed to the frame of the sash.

A pair of outer support brackets 46, which are preferably identical to the support brackets 41, are fixed to a lower part of the lower outer sash frame 25. The brackets 46 are apertured to receive removable pivot pin 48, only one of which is shown. The removable pivot pins 48 are identical to the removable pivot pins 43. The pivot pins may be threaded into the vertical jamb panes 19 or otherwise suitably and preferably removably connected.

As will be seen by examination of the drawing, the lower outer sash frame 25 is pivotal to an open position, shown in phantom in FIGURE 1, which is inward from the closed position shown in FIGURE 1. Both the inner upper sash 26 and the outer lower sash 25 are movable into a cavity 49 to an open position. The cavity 49 is an air space defined by the entire assembly. The space 49 is a dead air space when the sashes are in a closed position.

First and second pivot bars 50 are provided. The pivot bars 50 are pivotally mounted on pivot pins 51. The pivot pins 51 are carried by the vertical portions 19 of the jamb panel 11 at substantially the midpoint, both horizontally and vertically speaking. A guide groove 53 is provided in each end of the lower outer sash frame 25. A corresponding guide groove 54 is provided in the frame of the upper inner sash frame 26. First and second bearing slide pins 56 are carried by the ends of the pivot bar 50. One of the slide pins 56 is disposed in each of the

guide grooves

53, 54. At least the portions of the guide pins 56 which are disposed in the

grooves

53, 54 are formed of a suitable bearing material such as nylon.

The coaction of the pivot bar 50 and the connected window sashes provide several of the advantages of this invention. When the upper inner sash frame 26 is pivoted outwardly to its open position, the guide 56 disposed in the groove 54 slides along the groove causing the bar 50 to pivot about the pin 51. This movement of the bar 50 causes the other of the pins 56 to shift the lower outer sash frame 25 by coaction with the groove 53. When the upper sash 22 is pulled in a reverse direction from the open position to the closed position, a reverse action occurs and the lower outer sash simultaneously closes. Thus, with a simple push or pull movement, the inner and outer sashes are simultaneously opened or closed, as the case may be.

When the sash frames 25, 26 are positioned in their open position, shown in phantom in FIGURE 1, another of the advantages of the invention is obtained. Forced draft ventilation is automatically provided. An up-draft is almost always present along the sides of any commercial building. One of the explanations for this up-draft is that at substantially all times the walls of the building will be warmer than the ambient air. This tends to heat the air coming in contact with the building walls and cause it to rise. Wind striking the building also tends to rise upwardly to go over the building. Since the lower outer window and the upper inner window both are shifted into the cavity 43 when opened, a structure is provided which takes advantage of the natural up-drafts. The upwardly moving air moves through the opened lower outer window upwardly through the cavity and out the inner upper window to force air into the room.

This automatic forced air ventilation does not have a disadvantage which may at first appear to be present. A first blush examination would indicate that since it is bringing warmed air into the building, it might cause the interior of the building to be too warm in summer days. However, since the window is designed primarily for'airconditioned buildings, it will be seen that when such forced air is too warm, the window will be closed to take advantage of the air-conditioning. Further, even when used in buildings which are not air conditioned, the window causes air movement to prevent humidity build-up. High humidity is the true cause of discomfort when temperatures are high.

New or reconditioned buildings in the north-eastern quarter of the United States, for example, are almost invariably air-conditioned. Windows are sealed to provide economical air conditioning operation. This airconditioning, however, is only required for about twenty days a year. The rest of the time it is desirable to have a window which can be opened to avoid the claustrophobia effects of modern sealed buildings and to admit fresh air. Further, a building operating economy is obtained because it is not necessary to operate the air-conditioning system throughout the year to maintain fresh air in the offices. Since the windows are sealed when closed, the present window provides the advantages of scaled construction for economical air-conditioning operations. This window combines the advantages of sealed windows with the advantages of openable windows to eliminate the costly expense of forced air ventilation through air-conditioning systems when outdoor temperatures are comfortable whether it is desired to keep the interior of the building warm or cool.

Modern commercial buildings suffer tremendous losses to both heating and air-conditioning because of single thickness large panes of glass. Further, areas adjacent windows of commercial buildings are cold in winter and warm in summer because of convection. These disadvantages have all been accepted in the past because of the high cost of prior known double pane window construction and because prior known windows did not eliminate all of the disadvantages which have been eliminated by this construction.

To provide a sealed window when the movable windows are closed yieldable weather strip gaskets 58 are interposed Where appropriate between the sash frames and between the sash frames and the remainder of the frames. As an example, upper edges of the lower window sash frames and the lower edges of the upper window sash frames are stepped to accommodate the gaskets 58 and compress them therebetween.

Another of the advantages of the window is provided sol-2,605

in the removable construction. Manipulation 'of the clamps 39 permits removal of the window pane frames 32, 33, 37, 38. Thus, all of the windows may be cleaned from the interior of the building. No complicated external mechanisms are needed to raise and lower window washers along the outer walls of a building and the dangers inherent in external window washing are eliminated. The prior known alternate to window washers has been to build in automatic window washing systems utilizing modern detergents. Such systems are expensive to in stall, operate and maintain. The removable feature of the present window eliminates the need for such systems. A filter screen 60 having a frame 61 is also provided. The screen 60 is positioned such that it extends transversely and essentially horizontally across the cavity 49. The filter screen frame 61 is in abutment with the vertical portions 19 of the jamb panel 11, the upper outer fixed sash frame 24 and the lower inner fixed frame 27. Since the screen 60 is positioned substantially horizontally and not across the line of vision of a person looking through the window, it can be made of an extremely fine mesh so that it is both an ordinary insect screen and a pollen and dirt inhibiting filter, aswell. Y

The frame 6-1-has inner'and outer support members 63, 64 which rest'in an inner bracket 65 and an outer bracket 66. The brackets 65, 66 may be providedon the fixed sash frames 24,27 respectively. The frame -61 is preferably-notched ateach end to receive a cylindrical central portion 70 of the pivot bar 50. The notches are designated by the numeral 71. The notches 71 are shaped to snugly embrace the pivot bar center 70 at all positions of the windows to prevent the entrance of dirt or insects.

Examinations of the novel and disclosed window will reveal other advantages. The construction is such that the window can be open during a rain storm without fear of water getting into building. Additionally, the construction is such that it is burglar proof. While the sashes and screen are all removable, unless the windows are broken, a burglar cannot enter even when the windows are open. The removable pivot pins 43, 48 and the clamps 39 are so positioned that they cannot be reached from the exterior of the building, whether the window is open or closed and whether the screen is present or removed.

While the invention has been described with a great deal of clarity and detail, it is believed that it comprises a double pane framed window having an insulating air cavity therein and having a plurality of sash portions which are movable for cleaning. The invention is also believed to comprise a double pane window in which inner and outer movable windows are provided which, at the option of the user, may be opened or closed by movement of the inner movable window sash frame which causes simultaneous and corresponding movement of a connected and movable outer sash frame.

Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
