Fletcher, Orlando, Fla, assignor of one-third to Julian C. Renfro, Winter Park, Fla. Filed Apr. 2, 1962, Ser. No. 184,103 7 Claims. (Cl. 20-11) This invention relates to a trim unit for use with combination windows, and more particularly to the use of a novel trim unit utilized to hold multiple track window units more easily and securely in place in an aperture, as well as to provide a pleasing appearance for the rear side of such a window unit.
With the advent of the jalousie type of window utilized so extensively in modern building there has been a movement away from the use of heavy wooden window sash units with their proneness to rot and stick, as well as away from the use of large metal frame windows tiltable about their mid point, so exceedingly dangerous to pedestrians passing closeby.
The Olsen Patent No. 2,965,935 taught the use of highly satisfactory aluminum frame windows of very lightweight construction which have proven to be much more satisfactory than jalousie windows, in that latter windows are quite prone to leak cold air currents, and to prove quite cumbersome and space consuming when used in doors. The Olsen patent utilizes extruded aluminum material for the window frames in which trackways are formed directly therein to receive the upper and lower window sashes as well as the screens, this extruded material in one particular form being known as triple track. Rogers Industries, Inc. of Detroit, Michigan, assignee of the Olsen patent, is a supplier of such material. However, a certain amount of additional labor has ordinarily been involved after a window constructed of such material has been installed, in decorating and insulating the cavity defined between the triple track and the aperture in the building or door in which the installation is made.
My invention advantageously provides a novel trim adaptor designed for use with windows particulary of the type made of extruded aluminum material, which adaptor enables the window unit to be held securely in the aperture with a minimum of fasteners, while at the same time providing a most pleasing appearance for the outside of the window, a detail often overlooked by the builder and homeowner alike. Also my trim adaptor is so designed as to assure proper drainage of precipitation. This unit is available in a variety of sizes and configurations -to meet all normal and usual window installations, al-
though in reality trim adaptor material need be extruded in only a few standard widths or wall thicknesses in order to make my invention available in conjunction with a wide range of aluminum window units to complement in a most effective manner the use of such units in wall openings and in doors.
A trim unit according to this invention is therefore to be seen to be designed for use with a window unit constructed of lightweight channeled material, in the channels of which at least one window panel is slidable. My trim unit is arranged to be received on the opposite side of the aperture in which the window unit is to be installed, with said trim unit comprising a frame-like device arranged to interfit with the side of the window unit opposite the channels thereof. Tightening means are provided for drawing together the trim and window units into clamping relation about the periphery of the aperture, and means integral with said trim unit are brought into contact with the window unit during the installation procedure, which serve to enhance the appearance of the side of the window unit nearest the trim unit.
The trim unit according to this invention is constructed of extruded material in which the cross section thereof comprises a plurality of portions secured integrally together but angularly disposed with respect to each other. A first of these portions is designed to reside generally along a side of the aperture in which the installation is being made, and to be drawn toward the window unit during the installation procedure, whereas a second of these portions is disposed at approximately a right angle with respect to said first portion, and serves to reside against the outer surface about the aperture, so that the window unit will be held firmly in place. A third portion of the extruded material is disposed on the opposite side of the said first portion with respect to said second portion, with said third portion serving to contact the side of the window unit nearest said trim unit for the accomplishment of the beautification of the window unit.
These and other objects, features and advantages will be apparent from a study of the enclosed drawings in which:
FIGURE 1 illustrates in exploded relation the use of a trim unit according to this invention, utilized in conjunction with a modern lightweight window unit for holding securely and elfectively in the correct installed position in a door;
FIGURE 2 is a perspective view representing to a somewhat larger scale the lower right hand corner of the trim adaptor unit, this view exemplifying the trim material according to my invention as well as a typical constructional technique utilized in each corner of the adaptor unit;
FIGURE 3 represents a cross sectional view taken substantially horizontally through left and right side frames of similar windows, revealing the use of dilferent configuration trim material according to my invention, with central portions of the windows and screen removed in these views in the interest of clarity;
FIGURE 4 reveals the cross sectional appearance of top and bottom portions of a window the length of which has been foreshortened by the removal of the central portions of the windows and screen, with the trim material according to this invention used at both the top and bottom of this window being of a dilferent configuration from that shown in either portion of FIGURE 3;
FIGURE 5 is a perspective view revealing the configuration of a preferred embodiment of trim material in accordance with this invention; and
FIGURE 6 is a considerably enlarged view of the insulating material that may be used above the upper window as shown in FIGURE 4.
Referring to FIGURE 1, the outside unit or trim unit 10 and the inside unit 11 are shown in exploded relation with respect to a door 12 in which an installation according to this invention is to be made, with the units 10 and 11 being of a configuration as to be received and secured in interfitting relation in the aperture 13 of the door. Inside unit 11 represents a window and screen unit in accordance with certain prior art, and as revealed in FIGURES 3 and 4, the unit 11 may be constructed of extruded material of metal or plastic known as triple trac The window side frames shown in FIGURE 3 as well as the upper and lower portions of the window of FIGURE 4 reveal that the opposite aligned portions of triple track material form channels 11a for lower window panel 14, form channels 11b for receiving upper window panel 15, and form channels for receiving screen 18 of the window unit, it being understood that in accordance with state of the art techniques for lightweight metal windows, the windows are easily slidable in the pairs of channels in which they are installed, and each shoulder 11a of the middle track. 7
Referring to FIGURES 1 and 2 a trim unit according anagram of the windows as well as the screen is easily removable for the purpose of cleaning or repair. These figures will be discussed at greater length as the description proceeds.
My invention is principally concerned with trim unit 16 which is a frame-like structure typically made from trim material such as extruded aluminum, and which has been carefully configured and constructed to interfit with certain portions of the inside unit 11. As perhaps best seen in FIGURES 2 and 5, the extruded trim material from which the outside unit is constructed is, according to my design, arranged to have an angled. trim member 10a, a connecting leg member 1%, and an outer surface contacting member 100. As will be noted from the several figures of drawings, these three members or porto contact the outer surface of door 12 about the aperture 13, whenunit It has been disposed in interfitting relation with unit 11 as seen in FIGURE 3. Surface contacting member 11g of inside unit 11 is arranged to contact the inner surface of door 12 about aperture 13, with .tightening means being provided for drawing units 13 and 11 tightly together so as to cause surface contacting members 10c and 11g to tightly grip the door.
I prefer to use sheet metal screws 16 for drawing the units together, such as #6 SMS, ling. As seen in FIGURE 1, the screws 16 may be inserted in holes drilled in surface contacting member 11g near the corners of the unit 11, with the threads of these screws being arranged to enter undersized holes located in the corresponding positions on unit 10, being located at the, ends of the connecting leg members 10b. As will be seen from FIG URES 3 and 4, the threads of screws 16 are preferably received in configured end portions lite on the extreme ends of the connecting legs. a
It is significant to note that the trim material according to my invention may be extruded so as to disposethe angled trim member Ilia in any of several standard'or Y pro-established positions, so that upon the units it) and 11 being drawn together by screws 16, the outermost portion of the angled trim member will be brought into firm contact either with the shoulder lid on the back side of 'channel 11:: in the manner to be seen in the right hand l of the triple track material can leave exposed two tracks,
one track or none of the tracks, as may be preferred. It
is to be understoodthat although two different types of him material are shown in FIGURE 3, trim material of more than one type is never used on a given window.
Iprefer the configuration shown in FIGURES 4 and 5' wherein the angled trim member 10a is in contact with to my invention is preferably constructed by cutting the extruded trim material tov desired length'using angle each of the four corners, whichare right-angle members which interfit with adjacent trim .unit members in the general manner shown in FIGURE 2. Considerable rigidity is aflordedby having the corner angles 2 of a dimension in width that generally corresponds with the dimension of leg 10b on the side nearest 10a, as perhaps best seen inFIGURES 2 and 3. By disposing the curved end 1% of leg 1% into a somewhat encircling configuration, and by disposing a shoulder 1th at a location on member 10a spaced a short distance from 1017, a rather wide slot between lite and 10 is definedalong the length of all four members constituting a trim unit according to my invention, with each corner portion of such a unit being arranged to receive the corner members 22 in a close fitting relationship of the general nature of that shown in FIGURES 2 and 3. secure each half of each member 22 to the connecting leg member 10b of the respective trim member. Inasmuch as the members 22 are not of substantial lengthwise dimension, each slot defined between portions we and 101 is empty throughout most of its lengthas seen in FIG- URE'4. Although the members 22 could conceivably be disposed on the opposite or outer side of members 10b, such would cause large corners on the window unit and would also cause interference with the members 24 now to be described.
It will be appreciated that typically no screws are driven into the wood of the door 12 in order to secure the units It) and 11 into interfitting relation, for the four screws are generally being employed in the manner shown in FIGURE 1 for drawing the units together.
It will be appreciated that if aperture 13 is of considerable dimension in a door orwall, the side members of the trim unit may tend in use to bow outwardly some- 7 .what, and to prevent this I may employ a screw on each side members.
my invention to employ extruded trim material-that is configured to have a pair of spaced ridges 24 on'member 10b, extending for the full. length of the material. As will be obvious, and as shown in FIGURE 3, the trim material cannot'bow toward the side of the aperture inasmuch as the'ridges 24 effectively prevent this.
Referring to FIGURE 4, it'will be noted that the triple track material employed in the top and bottom portions of the trim unit have screw bosses 25 disposed therein.
The manufacturer vof the tripletrack material may provide/these screw bosses in the top and bottom portions of the window unit in order to receive the threads of metal cutting screws inserted into holes disposed in the upper andlower portions of the side members of triple track material. This is to say that the side members of unit '11 are designed to receive a pair of horizontally disposed screws at each upper and lower corner, with these screws extending through the thickness of the triple track material at channels 115 and lie, with threads of the screws cutting into and somewhat enlarging the slots of the screw bosses illustrated in channels 11b and in FIGURE 4. This information is'presented by way of background, for "the details associated. with the. construc. tion of triple track windows perse isnot apart of this invention.
Inasmuch'as it is usually desirable for window panel 15 to remaininitsuppermost position, I have found that a desirable amount-of insulation maybe inexpensively and yet efiiectively incorporated into the triple track window by the utilization of vinylweatherstrip, which may be of the configuration shown in FIGURE 6. By virtue of the eatherstrip 2 9being hollow, it can easily'deform as shown iniFIGURE4 upon being contacted by the upper-portion of window panel 15. The provision of a spearheads shaped locking portion 29 makesit quite a simple matter to'secure the Weatherstrip at the upper portion of the middle track 0f the window by simply insertingthe: locking portion 2 intoithe groove 'formed in the screw boss of upperchannelllb as shown in FIG- A screw v1.7 'is used to URE 4. It should be noted that the screws extending into the screw bosses do not interfere with the Weatherstrip 28, for the screws extend only for a short distance into the upper and lower members, and leave the entire central portion of the screw boss material unusued.
In some installations it may be found that precipitation may tend to accumulate in screen channel 11c, and accordingly I may provide one or more drain holes 26 disposed through the central portion of the screw boss so as to allow water to drain from the lower channel 110, as shown in FIGURE 4. As will be noted in this figure, this water will tend to drain along the exterior portion of the angled trim member a of the lower portion of the window and thence fall to the ground.
Water may also tend to accumulate in lower channel 11b and in some rigorous climatic conditions, it may be desirable to drill drain holes 26 in channel 11b as well as in channel 11a to permit water to drain into the space at the bottom of the window defined between the outside unit 10 and the inside unit 11. Because it is very undesirable for water to accumulate in the window unit, I provide so called weep holes 32 to be seen in FIGURE 4 as well as in FIGURE 1, whose function is to carry ofi any water before it can accumulate. Inasmuch as it may be desirable to extrude trim material specifically for top and bottom member service as well as specifically for side member service, the trim material extruded for top and bottom member use may have the connecting leg member 1015 sloped at a slight angle, say 2, toward the weep holes 32, or in other words, the leg 10b may preferably make a 92 angle with member 100 instead of a right angle therewith. By no means, however, is my invention to be limited to applications wherein different material is required for side member, or top and bottom member use, for obviously the use of ridges 24 is optional, but in any event would not interfere, even in top and bottom locations. Similarly, the two degree slant would not interfere in side member locations, although obviously if a ridge 24 is used near position 10a of the connecting leg, it would have to be of a slightly larger dimension than ridge nearer member 100 in order to prevent a non-symmetrical juncture with the aperture in the door or wall in which it is mounted. 7
Insulation of window units constructed in accordance with my invention is typically not required, although insulation between the units It) and 11 may of course be used if desired. The portion 10a may be fitted directly against the inner'portion of surface contacting member 11g as seen in FIGURE 3, as in the upper portion of FIGURE 4. However, inasmuch as water may tend to accumulate in the bottom member, I prefer to run a seam of caulking material on the inner portion of member 11g as seen in FIGURE 4 at 33, so that when portion 102 of the connecting leg is drawn close by the tightening of screw 16, a water tight joint will be effected. I also prefer to run a seam of caulk along the inner portion of surface contacting member 10c where all four sides of the outer window unit are in contact with the Wood of the door.
As is known, doors typically are supplied in standard thicknesses of 1% inches and 1% inches, so by extruding the trim material to be of a dimension to be used properly with the thickness of a selected door, my trim material may easily adapt a multiple track type window for use with the door. As will be apparent, an important dimension of the trim material is the dimension of the connecting leg 1012, which must be more or less in agreement with the thickness of the door or wall with which it is to be used. It is also desirable, however, to have the angled trim member 10a be disposed to contact the desired shoulder of the triple track material when the screws 16 have been tightened to draw the units 10 and 11 together in the aperture of the door.
Portion 10d of the trim material, which I prefer to call the return is designed to compensate for slight differences in door or wall thicknesses. This is to say, that if a standard thickness door is slightly too thick, the return 10d will dig into the wood of the door to some extent, as indicated in the upper portion of FIGURE 4, whereas if the door is slightly undersize in thickness, the return 10d will not dig into the wood of the door but rather will only slightly contact the wood and serve to compensate for the discrepancy.
It will thus be seen that by my highly advantageous trim material, the use of multiple track windows can be vastly extended, and each utilization of such windows be considerably enhanced aesthetically as well as be more utilitarian. By stocking complementary inside and outside units in standard sizes it will be possible for the retailer to easily furnish window units for apertures of Widths say 21 /2" or 22" and of a height of 34" or 54%". However, by maintaining a supply of'extruded trimmaterial on hand, the retailer can prepare custom made units in any nonstandard size as well.
Furthermore, it should be noted that my trim material may be employed in conjunction with windows designed to slide horizontally rather than in the vertical direction as illustrated, and in these instances it should be noted that the trim unit is virtually unchanged, except for perhaps the repositioning of drain holes therein.
Additional versatility of window units utilizing my invention is borne out by the fact that a plurality of windows can be mulled together by use of standard 1% inch H mull material in the event that two or more windows are to be grouped together.
As to the physical data of preferred trim material used in the construction of trim units in accordance with my invention, I prefer to use an extrudable aluminum such as 63 STS or similar, and when such material is extruded in the configurations illustrated in the drawings, weighs approximately .211 pound per foot in the dimension appropriate for 1%" doors, and .271 pound per foot for 1%" doors. This is typically .050 guage aluminum, with portion 101; being typically for 1%" doors, and 1%" for 1% doors, in instances in which the configuration of FIGS. 4 and 5 is employed. Member 10b is approximately door thickness.
