1 Claim. (Cl. 16-115) My invention relates generally to storm windows and specifically to triple track storm windows having disappearing handles.

It is among the object's of my invention to provide a storm window construction in Which handles for lowering the Window are included.

It is a further objectofr'ny invention to provide a storm window construction in which handles for lowering the window disappear and appear automatically.

It is yet a further object of my invention to provide a storm window construction in which handles for lowering the window do not interfere with the close placement of the storm window with respect to other storm windows in a double or triple track construction.

It is yet a further object of my invention to provide a storm window construction in which the handles for lowering the window are pleasing in appearance and unobtrusive.

Yet a further object of my invention is to provide a storm window construction in which the handles for lowering the window are simple to construct, durable and relatively inexpensive.

These objects and advantages, as Well as other objects and advantages, may be achieved by the device illustrated in the drawings in which:

Figure 1 is a front elevational view of a storm window partially raised;

Figure 2 is a cross-sectional view taken on the line 2-2 in Figure 1;

Figure 3 is a front elevational view of the window shown in Figure 1 lowered into contact with the window sill; and

Figure 4 is a front elevational view of the tab.

Referring now to the drawings in detail, which are merely illustrative of one embodiment of my invention, my storm window construction presents the conventional storm window in which the top, bottom and pair of opposite sides are formed of extruded aluminum strips 11. Each of these aluminum strips is usually provided with an inside channel 12 and an outside channel 13. A pane of glass 14. is usually fitted into the top channel 12 with an intervening cushion strip 15 serving to cushion'the glass in the channel and to formulate an air-tight seal by reason of its compressibility. The outside channel 13 of such strip 11 serves to receive the rails 16 at the side of the window upon which the sash runs as it is raised and lowered.

in constructing storm windows (which are primarily desirable because of their heat insulating properties) it has been found desirable to place these windows as closely as possible to the permanent window in order that the trapped air space shall not be too great. This object has been frustrated to a large degree because it has been necessary to include in each storm window frame, either a handle which extends from the front of the window or a recessed portion in order to enable the Window to be conveniently raised and lowered. The recessed portions frequently require a thickening of the strip 11. The handles nited States Patent Q attached to the surface of the strip 11 require that the various sashes be spaced from each other in order to allow for the passage of the handle as the windows are raised and lowered past each other.

Thus, in a double, triple or even quadruple track storm window construction, the overall thickness of the storm window construction is vastly increased by the inclusion of handles or other means to permit the raising and lowering of the window. The enlargement of the storm window construction thereby defeats, to a degree, the desired insulating properties and in addition, makes for a bulky and unwieldy storm window construction where multiple tracks are used. Also, the storm window must be spaced away from the primary window in order to allow for the passage of the handle as the storm window is raised and lowered.

The foregoing construction is conventional. My invention resides in the combination of this construction with the elements hereinafter set forth. In the bottom channel 13 a tab or handle 17 is positioned. This tab 17 has an aperture near the top which aperture is higher than its center of gravity so that when the tab 17 is suspended from this aperture, its lower end 19 will gravitationally drop down. The tab' 17 is mounted in the channel 13 on a pin 20 which is inserted into passages 21 in the strip 11 and frictionally engaged therewith. The upper portion of the tab 17 at one corner 22 is rounded so that the pivoting of the tab will not engage it with the roof 23 or top of the channel 13. The opposite corner 24 of the tab is higher so that when the tab pivots downwardly it will engage the roof 23 of the channel 13 and maintain the tab with its lower portion 19 substantially horizontal extending to one side of a vertical line passing through the mounting hole 18. Thus, force brought to bear on the surface 25 of the tab will not cause the tab to pivot further and will enable the window to be pulled downwardly. The bottom surface 26 of the tab is rounded so that as the window is lowered and the tab 17, as normally disposed, comes in contact with the sill 27, the tab will slide along the surface of the sill and will be moved upwardly into the channel 13.

Although the tabs may be used singly as a disappearing handle for aiding the lowering of the window, it is desirable to use them in pairs as shown in Figures 1 and 2. When the window is raised, by reason of the tabs 17 being eccentrically balanced, they drop down below the channel 13 and extend out of the channel, as shown in Figure 1, being maintained in that position by the engagement of the corner 24 with the roof 23 of the channel 13. When it is desired to lower the window, force applied to the surface 25 of each of the tabs draws the sash downwardly and when the window is pressed down to the sill 27, the curved surface 26 of the tab 17 pivots the tab to a position wholly within the channel as shown in Figure 3.

This construction provides handles for multiple track storm windows which do not extend from the front or back of such windows and enables the plurality of windows to be spaced very close to each other and enables screens likewise to be spaced very close to each other and permits the entire window construction to be placed very close to the primary window of the house to which the storm window construction is applied. When each window section or sash is raised, the handles for lowering automatically appear and they disappear when their use is no longer required. The insulation of such closely spaced multiple track storm windows is vastly enhanced by reason of the minimization of the enclosed air space between the various layers of windows. The esthetic appeal of windows with this type of construction is also improved, and the compactness of the entire window as semblage is also improved.

The foregoing description is merely intended to illustrate an embodiment of theinvention. The component parts have been shown and described. They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper substitutes for the said components and may have actually been known or invented before the present invention; these substitutes are contemplated as being within the scope of the appended claim, although they are not specifically catalogued herein.

I claim:

In a storm window, vertically slidably disposed within a window frame having a sill, and wherein the storm window comprises a bottom Window sill engageable strip having a channel extending lengthwise and opening through the bottom thereof, a pivot pin secured in said strip and extending transversely thereof, the axis of said pivot pin being disposed a predetermined distance from the bottom wall of said channel, and a handle for moving said storm window vertically within the window frame, said handle comprising an elongated tab having a pivot pin receiving aperture therein adjacent one end thereof, the tab being defined by opposite parallel side walls, first and second straight edges at the opposite sides of said aperture and converging in a downward direction away from the aperture, the said edges respectively merging into convex and concave edges extending in a general direction away from said first edge and defining with portions of said side walls, a convex window sill engaging surface and a concave finger engageable surface, said one end of the tab being in obtuse angular relation to said first straight edge andin acute angular relation to said second straight edge, said tab having first and second rounded corner portions at the junctures of the first and second straight edges with said one end of the tab, the high point of said first rounded portion being spaced from the axis of said aperture a distance no greater than the aforementioned predetermined distance and the center of gravity of said tab being so disposed that when the tab is free of said window sill, the high point of the second rounded portion will engage the bottom wall of said channel and upon lowering of the storm window toward said sill, said convex surface will engage the sill and the tab will be swung about the pivot pin in a clockwise direction to a position within said channel.
