DESCRIPTION OF THE PREFERRED EMBODIMENT The window assembly orstorm sash system of the present invention is adapted to fit in a rough opening in a house or other building. The window may be either single hung or double hung, but is conventionally a single hung three or four track or multiple track system. The window may be constructed so as to provide either an interior or exterior hung storm sash system.
Referring now to the drawing and more particularly to FIG. 1, an interior hung flush track storm sash system is shown. The window or window casing or assembly is illustrated generally at 10 and incorporates side jambs l2 and 14 (not shown) connected to a head frame 16 and a sill frame 20 to form the generally rectangular casing construction. The side jambs, head and sill frames are preferably made of an extruded aluminum or aluminum alloy. The parts are held together in a conventional manner using screws or other suitable fasteners. The window 10 additionally includes a fixed upper sash or. glass panel 22, a movable or slidable lower sash or glass panel 24, and optionally a screen panel 26 exterior of and adjacent the lower panel 24. The glass and screen panels are mounted in a conventional manner. The upper sash 22 can be movably installed if desired. Finally, the window 10 includes an upper storm sash 28 and a lower storm sash 30 adapted FIG. 6 is a top view illustrating the guide spring asto fit on the interior side of the window adjacent the upper and lower sashes 22 and 24.
The head, sill and jambs or window frame members are so constructed as to provide suitable tracks for the upper fixed sash, the lower movable sash, the screen panel, the upper storm sash and the lower storm sash. These frame members are preferably of a thermal barrier or thermal break design. One type of plastic thermal barrier is seen at 40 and 42, respectively. The side jambs 12 and 14 are also constructed of a similar thermal break or barrier (not seen). The thermal break is preferably constructed of virgin vinyl. Other suitable materials may be used. The thermal break may also be omitted from the window construction, if desired, or not required.
The upper and lower storm sashes 28 and 30 are essentially identical and are interchangeable. The upper sash 28 has side rails or stiles 29 and 31 (not shown) which are connected at their ends by the upper and lower rail members 36 and 38, respectively. The lower sash 30 has side rails or stiles 33 and 35 (not shown) which are connected at their ends by the upper and lower rail members 46 and 48, respectively. The storm panels 28 and 30 each include a glass pane 50 and 52, respectively.
The upper and lower storm sashes 28 and 30 are equipped with guide spring assemblies 70 mounted in the upper rails 36 and 46 on each end thereof and in the lower rails 38 and 48 on each end thereof. The guide spring assembly is described in detail hereinafter. The upper sash 28 has guide spring assemblies 70 mounted at the top thereof. The assemblies 70 are fixed into each side of the top rail 36 and the bottom rail 38 for meeting the side jambs 12 and 14, respectively. Each guide spring assembly incorporates a guide spring 71 of FIG. 5. Guide spring assemblies 70 are similarly fixed on each side of the top rail 46 and bottom rail 48 of the lower sash 30.
Standard spring loaded finger latches 80 are attached to each end of the bottom rails 38 and 48, respectively of the upper and lower sashes 28 and 30, respectively, just above the guide spring assemblies.
It is readily seen that each storm sash, either upper or lower one is substantially. identical and each sash has a guide spring assembly on each end of its top rail and on each end of its bottom rail.
Referring now to FIGS. 2 and 3, a four track storm window assembly 110 is illustrated in horizontal section. In FIG. 2, one storm sash 128 is shown in a partially installed position. The other storm sash 130 is shown in a fully installed position. In FIG. 3, both storm sashes 128 and 130 are seen in their installed positions.
To install a storm sash in a window frame, one stile of the storm sash is placed into a jamb track while simultaneously depressing a guide spring on the top rail of the sash and exerting a force toward the jamb track. The bottom rail guide spring is then depressed enabling the sash to enter the jamb track its full depth. The other stile of the storm sash is swung into position and placed in the oppositejamb track of the window. With the stile aligned with the jamb track, the storm sash is moved in the direction of the opposite jamb track until the guide spring stops against the jamb. The guide springs on the opposite side then pop out to retain the storm sash within both jamb tracks.
In FIG. 2 for example, the stile 129 of the storm sash 128 is placed into the jamb track 112a while exerting a force sideways in the direction indicated by arrow A and depressing the guide spring 71a on the top rail. Similarly, the guide spring on the bottom rail opposite the guide spring 71a on the top rail is depressed. The sash 128 is then permitted to enter thejamb track 112a a sufficient depth to permit the sash 128 to be swung or moved in the direction of the arrow B until the stile 131 is aligned with the opposite jamb track 114a. The sash 128 is moved in the direction indicated by arrow C until the upper guide spring 71b on the top rail and the lower guide spring on the bottom rail stop against thejamb 114 as seen in FIG. 3. Upper guide spring 71a and the lower guide spring opposite thereof then pop out in position adjacent the jamb 112 also as seen in FIG. 3. The storm sash is thus retained within jamb tracks 112a and 114a.
To remove a storm sash, the procedure is similar. For example, the guide spring 71a is depressed and the sash 128 is moved toward the jamb track 112a until the stile 131 clears the jamb 114. Similarly, the opposite lower guide spring is depressed and the sash moved until the stile 131 clears the jamb 114. The sash 128 is then swung outwardly in a direction opposite that of arrow B in the position shown in FIG. 2. The sash 128 is then moved away from the jamb track 112a and removed from the window 110.
The guide spring assembly and guide spring 71 are more clearly seen in FIGS. 5, 6 and 7. The spring 71 is preferably of a design as illustrated in FIG. 5. It is also preferably made of spring steel which has been passivated and hardened for maximum spring qualities. The end 710 of the spring 71 adapted to be located near the end of the stile and in contact with the jamb is preferably coated with nylon, Teflon plastic or the like. The entire spring may be coated if desired.
The guide spring assembly 70 is formed in each end of the top rail 236 and bottom rail 238. Thus each sash contains four guide spring assemblies 70. A notch or slot 281 is located in one side 236a of the top rail 236 of the sash 228 for receiving the spring 71 as seen in FIGS. 6 and 7. A similar notch 83 is located in the bottom rail 238 for receiving a spring 71. The top rail 236 has a second slot 285 therein for receiving the lower end 71c of the spring 70. A similar slot 287 is located in the bottom rail. The guide spring assemblies 70 on each end of the top rail and bottom rail of each sash are substantially identical. A sash pile 286 preferably of nylon or other similar material is attached to the rails 236 and 238 by adhesives or other suitable means. Although the particular configuration of the spring 70 may be varied somewhat, it is preferably of the configurations as shown in FIG. 5. The end 71a must also be so constructed that it is adjacent the slot formed to receive it and must be so located in the rail that the end of the guide spring in each end of a rail is adjacent the jamb, track when inan installed position as best seen in FIG. 3.
In installing and removing the storm sashes, the spring loaded thumb latch must also be moved inwardly a sufficient amount to enable the stiles to be in serted in the jamb tracks.
Upper and lower sashes are similarly installed and removed.
The present invention provides an aluminum singlehung window that not only is attractive but can easily be installed. In the most preferred form of the invention, a virgin vinyl thermal break frame keeps the cold on the :outside and the warmth insides-Ar Joutside box frame -'affords-easy,Haber; saving installation and .pro'' vides its; own attractivotrirn. fl'he trimmay bezcolored or plain asv desiredAlumingm self logking latchesaro n i y a' di he smwe P t e Ra h Hidden, direct, block and pulley-type sash balancesgre cessed in both jarnb sections plrovide smooth effortless i g I th weep holes flows moisture to the outside ofthe do ws Interior, ab er sh p i il i ii' i i'e'b ix ins} m .l lfi ng I I Q.

Aluminum alloy 6063-T is particularly preferred. The frame and sash are preferably made of extruded aluminum alloy with standard commercial tolerances. Weather stripping is preferable extruded vinyl in the sash bottom rail and polypile on stiles and meeting rail. Rigid type vinyl is normally used in the glazing area of the fixed lite and moving sash.
The inside storm sashes have extruded full aluminum frames with center rail overlap in two tracks. Glazing is with channel type soft vinyl suitable for reglazing. Corners of sashes are secured with spring steel corner clips or die cast corner keys. Glide tracks are extruded in jambs and head of inner window section to seal and guide for sliding of storm sash. Stiles and top rail of sash frame are weather stripped with polypile. The sashes are readily slidable and removable without the use of any tools. The top and bottom sash are identical and interchangeable and have spring retractable steel and nylon top guide pins and spring loaded die cast bottom latches. Three position ramps are located in jamb for lower sash.
Although the present invention is illustrated and described primarily with regard to an interior hung storm sash system, it is readily adaptable to an exterior hung storm sash system. It is only necessary that the window frame be so constructed that the sashes fit in appropriate tracks so as to be on the exterior side of the window. The construction of the storm sashes is substantially identical for either interior or exterior hanging.
The foregoing disclosure and description of the invention is illustrative and explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction, may be made within the scope of the appended claims without departing from the spirit of the invention.
