"and in particular to windows p One object of this invention is to provide a window "structure having standardized and in- -'terchangeableclosure units fitting into the window'openings of the buildingand consisting,- as desired, oi -window pane units, ventilatingunits with or without screen units, and closure units to effectively seal off the ventilating'units;

' Anotherobject is to provide a window strucbarriers so as to eliminate directcontact bein a filler unit is provided for enabling smaller units to'be fitted into a larger window opening and thereby reduce the variety of units" necessary to be manufactured as well as to make the various units more adaptable'to difierent conditions and circumstances.

Another object is to provide a window structure wherein a. ventilator unit, with or without a; screen unit, is associated with a closure unit having a tight gasket seal so asto efiectively prevent'air leakage and the excessive linear foot 'crack' lo'ss previously occurring in conventional windows.

Another object is to provide a window structure, as set forth in the preceding obj ects,'wherein v the various units may be interchanged from'top to bottom, whereby their order may be varied: "for example, wherein a ventilator unitqmay be placed either at thetop or at the bottom of the window opening or both, with a window pane unit in the central portion of the window opening or in .the upper or lower portions'thereof, asde- 'sired.

Another object is to provide a window strucwindow structure according-to the press vention, employing a single window pane unit Other objects 'an'd advantages of-th'' 'inviei-ition will become" apparent-duringthe course the llowing description of the acc onlpa nyin'g df y mas, wherein:

Figure 14 is. an enlarged fragmentary vertical section of'a modification of Figure tr-showing the use of a filler unit for 'spanning -the -space between the window opening and a window structure unit of the present. invention whichis I smaller than they opening to be filled.- 1 Referring to the drawings in detaiL' Fig'ure's 1 to 5 inclusive show window structures with iinterchangeableuunits according to a 'preferr d form of the present invention'and a'dap'te'd- -toi fitinto a given size of' windowiopenin'ginl a biiildthe various window 3 ing (not shown) of conventional construction, and capable of being arranged in different combinations of such units. In particular, the interchangeable units shown in Figures 1 to inclusive include units, generally designated as a large window unit It filling the entire window opening, a mdium'size window unit II combined with a" ventilator unit I2 for filling the same window opening, and a small window unit l3 combined with two ventilator units I2 for filing the same window opening. It will be understood that the units I0, I I, I2 and I3 may be made of different, preferably standardized sizes for mounting in window openings of different sizes,-as is found that the present invention enables the number of such units to be standardizedand kept at a mini t fering in size, are of substantially the same con- ..,structionand, for purposes of illustration, the

' medium-size window unit I I, as shown in Figures 2; and;4 will be describedas exemplifying the con- .}-'struct ion-also employedin the window units It -f andsl3. The window unit I I (Figures 2, 4 and 5) consists of top frame assemblies I4, bottom frame i assemblies-I5, and side frame assemblies I6. Since the side frame assemblies I6 are of similar --"construction'torthe top and. bottom frame assemblies-I4 and I5,'as shown by turning Figure 13 7 on itsaside and comparing it with the'central portion of- Figure 4, a description of the assemblies I4 and I5will sufiice for all. The top and bottom frame assemblies I4 andI5 are-also of similar --constru,ction except that they face in opposite di- -rections- They consist of outer hollow frame -Vmembers I'I' and'inner hollow frame members? w it h ;a hollow rigid insulating member I9 arj rranged between the members I I and 'I 8 to prevent direct metallic contact therebetween and thus to mretard theconduction ofyheat therebetwee'n. A retainin'g member 20, off L-shaped eross-section'is gages the portion 3| of the rigid insulating member I9. The inner frame member I8 is finally provided with an offset vertically extending portion 48 terminating in a horizontally bent portion 41 for Window-pane retaining purposes, as set forth below. The outer and inner frame members I! and I8 and the rigid insulating member I9 cooperate to'enclose chambers 48 and 49 respectively for receiving insulating material 50, such as fibrous material of a conventional type j well known in the building industry. Portions of -'portions-4B and 4'! of the inner framemember I8 calfioisecuredto'the outer frame members I? by fasteners 2| threaded into threaded holes 22 t .T j V: Y

In: detail, the outer frame-member I1 consists l forward've'rtical wall portion 23 facing outwwardly and having aiho'rizontal portion or first edge closure member 24 extending inwardly and -separated therefrom by an angularly bent portion -=2 5-pr9viding arece'ss or groove 28 between it and rt' ithe end'portion'fl of theouter portion 23. The

latter is also provided .Withan inclined'portion 28 including thethreadedholes 22 and terminating in-ramorizontal portion 29 substantially parallel =gto; the horizontal portion 24, but of a shorter ex- I tent.--."IThe' portions 28 "and 29 together form a gsecond closure member.. The various portions ,-which likewise i provided at its ends with bent the material itself have been omitted from the drawings in order to avoid unduly complicating the showing thereof and conflicting with the glass fibre, rock wool,fcork or other well-known andcohventional insulation.-

Toclean the outside of the single large ;-window:pane"54, it merely necessary to remove the grille unit "I'5I replacing it after the cleaning has been accomplished.

The assembly of the various units into a window opening; in a building is self-evident and ,follows fromethe foregoing description of the construction of these units. A large window unit I may be used alone in an opening or assembled sidebyside with other units ina large opening asshown in Figure 12, by means of the spacing members I 28 and cover strips I39 shown in Figure 13,-]. Optionally, a lower unit I2 may be com- .--bined with a medium-size window unit II Fi ures-2, 4 and 5), or two-louver units I2 may be combinedwith asmall window unit I3 (Figure 3) in ;,the.;manner previously described. Where a louverunit I2 is insufficient to fill the space, the filler unit-I35 is inserted and spans the gap between the louverunit I2 and the building opening asqshown'inFigure 14. Adjacent window .units I0,- II or I3 and louver units I2 may be Joined together in a single building opening by the use of the spacing members I28 and the elongatedcover strips I30 as shown in Figures 12 and 13.

In wintertime, the louver units I2 are sealed by theclosure units I20 (Figures 4 and 5) which tightly engage the gasket I4 and prevent leakage -of airby lineal foot crack loss. The various units may .be quickly assembled from standardized units prefabricated in a factory and a wide variety of units is thus afforded.

WhileI have shown and described my invention-in detail, it is to be understood that the same is to be limited only by the appended claims, for manychanges may be made without departing from the spirit and scope of my invention.

..What I claim is: 1. A building structure for mounting in a building openingcomprising a window unit having an open centered frame structure with a window :pane mounted, therein, and a ventilating .unit disposed in, said building opening independently ofand separable from said window unit and having an open centered frame structure with spaced ,ventilating louvers mounted therein, said win- .dow and ventilating units being mounted in edge tov edge abutting relationship in said building 'opening and having interengaging portions mating with one another in freely-separable inter- .fitting relationship along said abutting edges,
