United States Patent O 3,145,433 WEATHERSTR@ ASSEMBLY FR DOUBLE HUNG WNDWS Merlin K. Jones, Cinton, iowa, assigner to Curtis Compmies, Inc., Ciinou, iowa, a corporation of Iowa Filed June 4, 1962, Ser. No. 199,835 2i) Claims. (Cl. 29m-52) This invention relates to a weatherstrip assembly for double hung windows.

One object of the invention is to provide a combined weatherstrip and guide assembly for double hung windows wherein elongated members in the form of metal extrusions are provided in pairs at each side of the window frame, each pair being connected together by an elongated member in the form of a hard plastic extrusion so that the plastic provides a thermal barrier between the metal extrusion on the inside of the house and the one on the outside to prevent frosting and condensation or sweating due to temperature differential, and to minimize loss of heat from inside `the house by conduction through the metal extrusions.

Another object is to provide metal and plastic extrusions which may be quickly and readily assembled together to form a rigid weatherstrip member without the necessity of using bolts, rivets or other fastening means, the extrusions being provided with pivot groove and bead arrangements that cooperate with snap-in groove and bead arrangements to accomplish such assembly.

Still another object is to provide the metal extrusions of such design that they may enclose counter-balance springs for the sashes, and may retain compression springs for taking up play between the two jambs of the window frame and the intervening extrusions and sashes.

A further object is to provide the extrusions so designed that sealing gaskets may cooperate between them and the side jambs of the window frame for weathersealing the backs of the eXtrusions with respect to the jambs.

Still a further object is to provide a modified form of plastic extrusion with which a special type of soft plastic tube may cooperate to serve as a weather seal between the weatherstrip assembly and the side jamb of the window.

An additional object is to provide mounting clips for the extrusions which are readily attachable to the side jambs and into which the extrusions may be snapped and will thereafter remain in position when the sashes of the window are removed from between the weatherstrip assemblies.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my weatherstrip assembly for double hung windows, whereby the objects above contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in detail on the accompanying drawing, wherein:

FIG. l is a horizontal sectional view through a double hung window frame showing two of my weatherstrip assemblies and a pair of sashes mounted therein.

FIG. 2 is a perspective view of one of the mounting clips for the weatherstrip assembly.

FIG. 3 is an end view of a metal extrusion, two of which are used in my weatherstrip assembly.

FIG. 4 is an end view of a plastic extrusion, one of which is used in my weatherstrip assembly.

FIG. 5 is a view similar to a portion of FIG. l show ing a modified form of plastic extrusion and a gasket tube in the form of a soft plastic extrusion associated therewith.

FIG. 6 is an end View of the modified form of plastic extrusion of FIG. 5.

FIG. 7 is an end view of the soft plastic gasket tube in the shape it normally assumes.

ICC

FIG. 8 is an end View of a metal extrusion and the plastic extrusion of my weatherstrip assembly during an initial position of the parts during assembly, and

FIG. 9 is a similar view showing the position of the parts when the assembly is nearly completed.

On the accompanying drawings I have used the reference character A to indicate in general a metal extrusion and B a generally T-shaped hard plastic extrusion. Two of the metal extrusions A (which are identical for economy of manufacture) and one of the extrusions B is used to form a complete weatherstrip assembly at one side of the window frame, and two such assemblies are shown in FlG. l between the side jambs l0 and the upper and lower sashes l2 and i4. The sashes l2 and 14 may be of wood and are provided with guide grooves 16 that cooperate with guide beads 18 of the extrusions B.

At the right hand side of the window shown in FIG. 1 the weatherstrip assembly is seated against a spring mounting clip 19. The weatherstrip assembly at the left hand side of the window is provided with several vertically spaced compression springs 7.2 that are mounted in grooves 30 and 32 of the extrusions A. These springs engage against a mounting clip Z6 similar to the mounting clip i9. The clip 19 as shown in FIG. 2 is channelshaped, having resilient flanges 24 terminating in hooked marginal edges 26. Prongs 2S are struck out of the web or back of the clip to be driven into the side jambs 10 in lieu of nails, thus simplifying the assembly procedure of the clips 19 and Ztl with respect to the jambs. Several of the clips are provided vertically spaced along the jambs. The usual blind stops 6,2 and inside stops 64 are shown installed on the side jambs lil of FIGS. l and 5.

The weatherstrip assemblies may be inserted into the mounting clips 19 and 29 by springing the anges 24 apart and thereafter the hooked marginal edges 26 normally retain the assemblies in mounted position in the clips. It will be noted the clip 19 is not as deep as the clip Ztl in order to hold the weatherstrip assembly at the right side of the window against the back of the clip 19 while the assembly at the left side is spaced therefrom to permit floating action as dictated by the compression springs 22 and the sashes 12 and 14 intervening between the two extrusions B. The spring clips -19 and 20 permit removal of the weatherstrip assemblies if desired vfor painting of the wood parts of the window frame.

The eXtrusions A are provided with longitudinally eX- tending, open spring chanels 34 in which counterbalance springs 36 for the sashes 12 and 14 are mounted. If desired plastic or metal spring covers 38 may be sprung into opposite grooves 40 of the extrusions A to cover the counterbalance springs 36 throughout the portions of their travel where such covers will not interfere with the connection from the bottom of the spring to the sash.

Sealing gaskets 4@ and 42 of sponge rubber, foamed plastic or the like may be provided for weather-sealing the space between the weatherstrip assemblies and the jambs. As between the weatherstrip assemblies and the sashes l2 and 14 the grooves 16 and beads 18 form contact surfaces of considerable extent to eifect a weather seal and provide a smoothly operating guide assembly for the sashes during their sliding motion. I have found that the plastic-to-wood engagement is excellent for slideways without excess friction yet sufcient friction under the action of the springs 22 to hold the sashes at all adjusted positions where they are not substantially counterbalanced by the springs 35. Uniform sliding action is also continuously had without lubricant of any kind.

In FIGS. 5, 6 and 7 I show a modification wherein the hard plastic extrusion B has an additional channel 44 for mounting an elongated soft plastic tube-like member C. The member C may be in the form of an extrusion trusions C thus eliminate the necessity of providing sealing gaskets such as shown at 4t) and 42 in FIG. l, and is a more satisfactory installation. Foamed plastic passes air if soft, and if of the closed-cell type it is too diicult to compress, but a soft plastic tube is not subject to these shortcomings.

To facilitate ease of assembly of the extrusions A and 'the extrusion B with relation to each other without the necessity of using bolts, rivets or the like, l have designed the extrusions A with pivot grooves 43 to receive a pair of pivot beads 50 of the extrusion B. The extrusion B is provided with a pair of snap-in grooves 52 and each extrusion A is provided with a snap-in bead Sii. Leading to the groove 52 is a surface S6 which as shown in FIG.

8 is inclined relative to a circumferential line 58 drawn from the pivot center of the groove 48 and bead Sti'. Accordingly the parts may be positioned as in FIG. 8 with the snap-in bead 54 at the position indicated 54a and will make contact with the surface 56. As the extru` sion A is then rotated counterclockwise relative to the extrusion B, for instance to the position shown in FIG. 9, the bead 54 will attain the position 54h, springing the web 6i! of the extrusion B to the position shown. Then when the snap-in bead 54 iinally snaps into the snap-in groove 52, this web 60 will still be under some tension as illustrated in FIGS. l and where these Webs are slightly curved but not as much as shown in FIG. 9. This arrangement provides an excellent pivot-snap-in assembly eliminating any fastening means and resulting in a rigid weatherstrip assembly comprising two metal members A and one plastic member B.

Any suitable metal such as aluminum or the like may be used for the extrusion A, and any suitable hard plastic such as vinyl, polystyrene, nylon or polypropylene may be used for the extrusion B. The extrusion C may be made of ilexible vinyl or polyethylene for distortion to the shape shown in FIG. 5 to accomplish eiecting sealing.

From the foregoing specification it will be obvious that I have provided a weatherstrip assembly which eliminates frosting and condensation by reason of the extrusion l B being formed of plastic which is a heat insulating material. Heat transmission through plastic when compared to that through aluminum has a ratio of about one to one thousand. Plastic material has sound deadening properties thus reducing the transmission of noise through the window opening.

The design of my weatherstrip assembly is such that the extrusions A may be identical in shape and may be of rolled section instead of extrusions if desired. The web 60 of the extrusion B is in tension and the angle of the surface 56 is important as it permits assembly as shown in FIGS. 8 and 9 and locks the weatherstrip assembly in assembled relation after the bead 54 rides smoothly up the incline. After assembly the parts A and B form a rigid assembly, the parts of which are almost impossible to separate from each other except by longitudinal movement of one relative to the other. Once assembled however and mounted in a window opening it is seldom necessary to disassemble them except for possible replacement of broken parts.

Some changes may be made in the construction and arrangement of the parts of my weatherstrip assembly as herein disclosed without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modied forms of structure or use of mechanical equivalents which may reasonably be included within their scope.
