The present invention relatesgenerally to ,.closures, yand more, particularly to Anovel improvements "1n the `construc- .tion andinstallation ofthe .SD-.called combination storm and screen doors. i l

ICombinationdoors Iofthe character mentioned above .are very .well 'known and .in .ever 'increasing popularity :In the very .great majority, these doors are `fabricated vshape or .theross-section pattern of .these aluminum extrusionslhave, up -.to the, present time, followe'd a somewhatqconventional form, .thatis,an.acceptedpattern which .the fabricators `have used ,to makegtheircombinationdoors. We have found, however, 4thatdoorsgmadefrom 'these old forms lof Vextruded sec.tious. arefdeticient in many respects.l In particular, .they `lack the, proper lmeans .'.for `qliickjlyand sturdily ,hinging zsaidrrloors. Also, lack intheA meausieffective ,neatly `to t v.the ,.doorways finto which .the said `doors are tobe. installed.

Actually, it might well .be .said here that Hthe material-.that is the..alun1iru1m-'is.v prima.rily chosenforllong .service ordurabilityrof the door.-itself. "Itshoul'd follow, therefore, A.that .the ,fway of .constructing,thedoorlbe such as toprovide the y.means ,for .durable installation, commensurate with the` durability '.,o'f the` material of ,the door.

.Itis a primeobjectottourtinvention toprov-ide 1a.generally improved construction for a combination storm. and screen door.

Another ,object .of .ouriuvcntion .is to ,provide novel and improved means for associating a storman'd screen door with the muck-:frame .scorn-monito'` the .installation of adoor. of thiszcharacter.

A further object of the inventionis .ft-ogprovideanovel method OLdependably installing .a .door-'into anfexisting `framework of a doorway.

A still further object of our invention is to provide a novel arrangement for attaching hinges to a door.

A still further object is to provide a novel arrangement for sealing the bottom side of a door with the saddle piece of a doorway.

Other `objects and features of the invention will more fully appear from the following description and the appended claim.

In the said description, reference is had to the accom# panying drawing, in which:

Figure 1 is an illustration of a combination screen and, storm door made in accordance with our invention.

Figure 2 is a view, on an enlarged scale, of a section of the above illustrated door, the view being taken along the line 2 2 of Figure 1.

Figure 3 is another large-scale section, .as taken along the line 3-3 of Figure l.

valways-a necessary `adjunct ithereof in ordenproper'ly to-y install "and fit the door Vinto .an existing conventional doorway. The intermediate vbuck-frame.mentione d above is-one that is 'formedlby way 'of'an extrude'dstrip orbarn whose vcross sectional pattern resembles the letter Z.' Hence, strips -of this character are `commonlyloiownjin thefa-rt as Zlbars; the term appearing hereinafter. IItis `also tobe understood,that-in`thegretailibusiness of @doors lf'ithe character at issue,;the-ven'dor most always 4sells the installation service withthepro'duct, so that the 1price is'normally 'set so as to vinclude the item or the ,costof 'the time'required for .a man to .perform -the.service of installation. In many instances, `this service cost is a causefor unhappy business transactions, due v.principally to jthe lack of good standard designs Vfor-.doors ,of 'this .sort. 'Our door is thus designed to minimize y.past troubles .of installation. Moreover, .our dooriincludes new provisions 'for improving the quality ofthe installation. An .important feature of our door residesin the factlhatthe said door may be sent out`for`its 'installation withoutpre-A vious determination of Whetherit'is to"be'hiugedso as to open. to the right ortothe left.

InFigure yl of the drawing, ourrdoor is .indicate`d generallyby the numeral 10, and the associatingfbuck-,frame as 11. Thed-oor frame proper includes the two .vertical side members 10a and 10b, andthe topand ,bottommembers 10cvaud 10d. rAll of these. frame members are. made 'from hollow .aluminum-extrusions or bars., rthe -cross-section'of Which is clearlyshowninFigure 2. .There itis seen that the sectional patteruhas a hollow` ,core.12, anda conformity which includesaninnerbead l3ftogether with suitable tins 14and ,15. The latter are utilized tohold the interchangeable, panels .used f in .doors vof thischaracter. 'The panels and the arrangement thereof form,no. part .of the present invention andneed not hereinbedisclosed in 4further details, exceptto point outthatsuch .panels .are located by wayofthe abovementionedns 14 `andlvS. and {Iittedinto the spacesindicated inthe-drawing as ,16 and 17. -.These two spaces, as is seen,.,are divided by meansof the .'mullionv piece 18. Justbelowthespace 17, .another .mullion piece v19 is utilized so .as .tofurther divide the doorfand provide means -for .permanently securing tothe Llowerportion of the door.alrickplatelll.

The

mullion pieces

18 and 19 are interlocked at each their ends fto the side members 10a and 10b, and further secured by means of screws in the usual manner. In turn the said side members are solidly secured to their associating top and

bottom members

10c and 10d. For this purpose, We use corner inserts 42, such as the one shown in dotted lines in the lower left hand corner of the illus-` trated door. These corner pieces have right angularly extending arms 42a which tightly telescope into the openings 12 -of two adjacent frame members; screws being used to retain the parts together. Both the

mullions

18 and 19 are made from an extruded shape 21 the crosssection of which is illustrated in Figure 5. The front portion 21a of the extrusion 21 is not only designed for appearance but also for utility. As seen in Figure 5, the extrusion 21 has, at the junctions of its beaded portions 13 thereof and its curved face 21a, a pair of anges 22` and 23. These extend in a sort of complementary fashion so as to form :top and bottom recesses 22a and 23a; the

top recess being deeper than the recess of the bottom, as may be observed. The purpose of this arrangement is to provide means for attaching on to the door any decora-t.

forming the extruded shape, which is used to make the four side members of the door, with a deep recess or channel in its outer edge, as is seen in Figure 2. The recess 25 is undercut as indicated, and, by way of this arrangement, al1 four side members of the present door are outwardly channeled in a manner to offer means for interlocking with said door certain elements of installation now to appear. In Figure 6, there is shown one of the hinge coupling elements 26, which are adapted to 'tit in the abovementioned channel and serve to clamp the hinges 27 to the door 10. Also, in Figure 3, there appears another type of such insertable elements. This element is designated as 28, and its purpose is to cooperate in forming a seal for the said door with the saddle piece 30 used in an installation of a door of the present type. Further description of the

elements

26 and 28, together with their respective effectiveness in the construction at issue, will appear more fully in connection with the explanation of the manner of installing our door 10.

The buck-frame 11 is formed by way of the Z-shaped extruded stock aforementioned which form thereof the side sections 11a` 1lb and llc. The said stock has a facing flange 31, a web portion 32 and a backing flange 33. The latter has the customary longitudinally extend ing recess 33a which is utilized to hold a weather strip 34, efective to seal the door to the buck-frame. In accordance with the present structure, we form the extruded Z-bar stock with an additional small flange or lip 35, as is shown in Figures 2 and 4. in order fully to make our invention understood, a review of the parts will be had in connection with a complete description of the manner of installing our door, this now follows:

As a first step, one of the vertical lengths 11a or 11b is provided with the customary three `hinges-11b being selected as an example in the drawing. This provision entails punching in its ilange 3l a set of three slots 31a,

and notching the lip 35 thereof with notches 35a, as is clearly shown in Figure 4. In respective order, one side (the left side) of each of the hinges is then inserted through its respective slot 31a and is riveted, by way of its central hole, to the web portion 32 of the Zshaped length; it being understood that there are three holes in each side, as appear in Figure 4. With a length prepared in the manner above described, the installer will proceed to place the said length on to and along the outer edge of the portion 10b of the door, so as to spot the holes in the left sides of the hinges on to the stock of the door forming the bottom of channel 25. The door is then drilled in correspondence with the markings and, as a next step, the hinges are taken apart by removing the pins 27a so that their left side may be attached to the door in accordance with our invention. The attachment consists of inserting into the channel 25 a set of three of the inserts or slugs 26 and of locating these slugs so that their holes 26a thereof will match the drilled holes in the door. This is followed by freely inserting the screws 37 through the hinges and through the slugs so that they may be threaded only into the stock of the door. Such an arrangement, as will be understood, will cause the slugs to be drawn to the hinge parts and that both will be clamped solidly to the door. It is to be understood that before the screws 37 are tightened the respective faces 2Gb of the slugs are not quite in Contact with the hinges. Now thevlength 11a may be permanently secured to the frame 38 of the doorway and the door mounted thereto by reassembling the hinges 27.

As previously stated, we provide a novel way of sealing the bottom member 10d of the door with the saddle piece 30. To this end, we slide into the channel 25 of this bottom member the aforementioned insert or bar 28. In order to extend the sealing bar 28 fully across the bottorn of the door, the lower end of both the members 10a yand 10b is slotted to correspond with the channel 25, as

will be understood. The bar 28 is provided with the 1ongitudinally extending flange 28a which is designed in a manner to clinch with the weather strip 30a of the saddle piece 30, as is shown in Figure 3.

Having thus described our invention, by way of the particular embodiment herein illustrated, what we claim is:

In a door of the character herein described, in combination: a hollow framework forming said door; an undercut channel formed along the edge of said framework; means for solidly securing hinges to said hollow framework, said means including individual pieces slidably insertable into said undercut channel and movable to any position for coupling with .said hinges; said pieces having holes matching holes in the hinges; said pieces and said hinges being clamped to the edge of Said door by screws that are passed freely through both the pieces and the hinges and then threaded into the stock of the door at the bottom of said channel.
