This invention relates to multiple window constructions, and included in the objects of this invention are:
First, to provide a multiple window construction wherein the inner and outer windowpanes, as well as their respective substructures, are isolated thermally and vibrationally from each other so as to minimize the transmission of heat and vibration, inwardly or outwardly. through the Wind-ow construction.
Second, to provide a multiple window construction wherein, after installation of a peripheral frame component, the preassembled remaining components of the window may be installed as la unit, thus permitting factory assembly of the major components of the multiple window construction.
Third, to provide a multiple window con-struction which incorporates novel means to facilitate insertion of the preassembled components of the window into the peripheral frame component.
Fourth, to provide a multiple window construction wherein virtually all the parts m-ay be formed of metal or elastomer extrusions.
Fifth, to provide a multiple window which provides a concealed space between the windowpane-s to receive a desiccant in lorder to ensure a moisture-free interior.
With the above and other objects in view, as may yappear hereinafter, reference is directed to the accompanying drawings in which:
FIGURE 1 is a typical transverse, sectional view through any of the four sides of the Window construction, arranged as a double window;
IFIGURE 2 is a fragmentary plan view of the accoustical pan installed between the windowpanes, the view ybeing taken from 2--2 of FIGURE l;
FIGURE 3 is a fragmentary, sectional view taken through 3 3 of FIGURE l, showing particularly the means whereby bolts extending from one of the inner frame members are joined to the outer frame member;
FIGURE 4 is Aan exploded view showing the major components of the double window construction in cross section;
FIGURE 5 is a fragmentary sectional view, similar to FIGURE l, showing a modification wherein the Window `is arranged as a triple window construction;
FIGURE 6 is another fragmentary sectional View, showing a further modification wherein the window is arranged as a quadruple window construction.
Reference is rst directed to FIGURES 1 through 4. The double window construction here illustrated is formed almost entirely from a plurality of extruded metal parts which are separated from each other by yieldable sealing and cushioning means, which are also extrusions, in this case formed Iof rubber or other elastomer.
The double window construction includes an outer mounting frame member 1 which is formed in-to a rectangular outer frame structure. The mounting frame member 1 includes a transverse web 2 provided along its Weatherside margin, or left side margin as viewed in the drawings, with an internally directed weatherside flange 3. The flange 3 terminates in an inturned lip 4 and is pro- `vided along its inner wal-l, confronting the inturned lip, `with a retainer bracket 5 of angular cross section.
The inturned lip 4 and retainer bracket 5 receive a 3,203,653 Patented Aug. 31, 1965 ICS sealing mem-ber 6, yformed of rubber or other elastomer, and having a V-shaped end 7 which fits over the inturned lip 4 and a lateral flange 8 which extends into and is retained -by the bracket 5. The side wall of the V-shaped end 7, which faces toward the web 2, is provided with parallel sealing lips 9. The function of the sealing member d will be brought out more fully hereinafter.
Near the weatherside flange 3, the web 2 is interrupted by a channel-shaped mounting pad 10, extending internally from the web member, and terminating in an inclined ramp surface 11 which slopes toward the roomside margin of the web 2, that is, away from the weatherside flange 3. The ramp surface 11 may include an extension which projects laterally fr-orn the mounting pad 1?. The margin of the ramp surface 11, nearest the weatherside flange 3, is provided with a stop 12.
The roomside margin of the web 2 is provided with a roomside mounting pad 13 terminating in a ramp or inclined surf-ace 14, disposed at a lesser height from the web 2 than the ramp sur-face 11. The ramp surface 14 is also provided with a stop 15 corresponding to the stop 12. When the mounting frame member 1 is formed into a rectangular frame structure, the opening defined by the outside mounting pad 10 is smaller than the opening defined by the inside mounting pad 13.
The roomside mounting pad 13 is provided with a slot which is open towards the roomside margin of the web 2. The confronting Walls of the slot are provided with screw/receiving serrations 16.
The rectangular, outer window frame structure, formed by the mounting frame member 1, is set into a window opening provided in a building wall 17 and supported relative to the sides of the opening by suitable shims or mounting blocks 18. Bolts 19 secure the outer frame structure in place. In addition, grouting or other cementious material is placed between the roomside and Weatherside margins of the web 2 and the surrounding walls of the window opening. At the weatherside margin of the web 2, a suitable sealant 21 is also applied.
The weatherside portion of the outer frame structure formed by the mounting frame member 1 receives a Weatherside windowpane frame member 22 formed into a rectangular frame substructure. The weatherside windowpane frame member 22 includes a cross web 23 having a weatherside end 24 offset toward the mounting frame member 1. A weatherside-directed lip 25 overlies the offset Weatherside end 24 and an internally directed catch lip 26 confronts the lip 25.
At the side of the oifset end 24 confronting the Web 2, there is formed a Weatherside facing channel 27 which conforms to the V-shaped end 7 of the sealing member 6, and is sealingly engaged by the sealing lips 9.
The web 23 of the weatherside windowpane frame member 22 is provided with an external mounting channel 2S directed toward and in registry with the weatherside mounting pad 1t). The mounting channel 28 receives a mounting cushion 29, formed of rubber or other elastomer, and having lateral sealing lips 39 which engage the side walls of the mounting channel 28 and peripheral sealing lips 31, which seat on the inclined ramp surface 11 in a folded condition. Between the ramp 11 and the mounting channel 2S, the cushion 29 is provided with lateral shoulders to limit entrance of the cushion into the channel.
Disposed internally of the cross web 23 is a weatherside windowpane stop flange 32 around which is wrapped a gasket strip 33, formed of rubber or other elastomer, and having an interlocking ange 34, the extremity of which is received in a groove 35 provided in the stop ange 32. The opposite margin of the gasket strip 33 overlies a portion of the web 23 adjacent the stop flange 32.
A weatherside windowpane 36 is located at the weatherside of the stop flange 32, over the lip 25. lts margins yieldably bear against the interlocking flange 34 of the gasket strip, Aand the windowpane is positioned within the rectangular opening formed by the weatherside windowpane frame member by means of mounting blocks 37, formed of rubber or other elastomer. The weatherside margin of the windowpane 36 receives a sealant strip 3S,
lformed of rubber or other elastomer, and which may be lof the web 43 is offset as indicated by 44, corresponding to the offset weatherside end 24. Similarly, the offset end 44 is provided with an overhanging lip 45 which confronts a catch lip 46 at the extreme roomside end. Adjacent the offset end 44, the web 43 is provided with mounting channel 47, corresponding to the mounting channel 28, but of greater depth. The mounting channel 47 receives a second mounting cushion 29 which engages the roomside mounting pad 13.
The web 43 is provided at a side opposite from the mounting channel 47 with a roomside windowpane stop flange 48 corresponding to the weatherside windowpane stop flange 32. The flange 48 is equipped with a gasket strip 33 having an interlocking flange 34 wrapped over the extremity of the stop flange. A roomside windowpane 49 rests against the interlocking flange 34 and is peripherally supported by mounting blocks 37.
The roomside margin of the windowpane 49 is covered by a roomside Window framing member 50 of channel shaped cross section corresponding to the weatherside window framing member 39. The framing member 50 is provided with a laterally facing marginal channel 51 which interlocks with the lip 45 and a latching lip 52 which engages the catch lip of 46. A sealant strip 38 is interposed between the framing member 50 and the roomside windowpane 49. The surfaces of the two framing members 39 and 5t) covered by the sealant strips 33 are preferably serrated or otherwise roughened to provide interengagement with the surface of the sealant strip.
The roomside margin of the web 43 is provided with a roomside cover plate or flange 53 which covers the mounting frame member 1 and overlies the margin of the building Wall 17 surrounding the window opening. The roomside cover plate 53 is provided at its margin remote from the web 43 with a slot 54 directed away from the web 43. The slot 54 receives an offset flange y55 formed of rubber or other elastomer, and attached to a sealing tube 56 interposed between the marginal portion of the cover plate 53 and the wall 17.
The roomside face of the cover plate 53 is provided with a channel 57 disposed in registry with the slotted edge of the mounting frame member 1 having the screw-receiving serrations 16 therein. Screws or bolts SS extend through openings in the channel 57 .and screw thread between the serrations 16. The head of each bolt is provided with a grommet 59 yformed of rubber or other elastomer. The channel 57 is covered by a cover strip 60 having inturned flanges 61. Fitted between the inturned flanges 61 are a plurality of retainer clips 62 of channel shaped cross seetion and including spring flanges 63 which engage internal ribs 64 provided within the channel 57.
The cross webs 23 and 43 of the weatherside and roomside windowpane frame members 22 and 42 are disposed in a common plane and terminate in confronting relation to each other. The confronting margins of the Webs are provided with flanges 65 which extend toward the mounting frame member 1 in parallel relation to each other. The extremities of the flanges 65 have outturned retainer lips 66. The confronting flanges 65 are connected by a vibration isolating and sealing member 67 formed of rubber or other elastomer. The isolating member is essentially W-shaped; that is, the isolating member includes a central flange 68 which lits between the confronting flanges 65 and side flanges 69 overlying the remo-te sides of the flanges 65. The outer surfaces of the side flanges 69 are provided with sealing lips 7l). The isolating member 67 is adapted to lit within a retainer member 71 of channel-shaped cross section. The side walls of the retainer member which lit over the sealing lips 7l) `are serrated to assure a sealing lconnection and also to secure the retainer member 71 on the isolating member 67.
The space between the gasket strips 33 which cover the windowpane stop flanges 32 and 4S receives an acoustical pan 72 having side flanges 73 which bear yieldably against the gasket strips 33. The web of the acoustical pan between the flanges 73 is provided with slots 74 or is otherwise perforated in a suitable pattern. The space between the acoustical pan and the frame members 22 and 42 is filled with a sound-absorbing material 75 and desiccant. The sound-absorbing material may be glass wool or fibrous material. The desiccant may be silica gel.
The window construction is installed as follows:
An outer frame structure is formed from four of the mounting frame members 1 and is set in place within a window opening. The sealing member 6 is fitte-d over the weatherside of flange 3. The remaining components of the window construction are preassembled as a unit and then slipped laterally within the outside frame structure. The mounting cushions 29 ride on the ramp surfaces 11 and 14. The weatherside facing channel 27 engages the sealing member 6 and the bolts 58 are screw threaded into the serrations 16 so as to draw the roomside cover plate 53 and sealing tube 56 snugly against the roomside wall surface.
It will be noted that the weatherside windowpane carrying substructure is isolated from the roomside windowpane carrying substructure by reason of the gasket strips 33 and isolating member 67. Both of these substructures are isolated from the outer frame structures by the mounting cushions 29. The weatherside windowpane substructure is also isolated fro-m the outer frame structure by the sealing member 6, and, correspondingly, the roomside Windowpane substructure is isolated from the wall by the sealing tube 56 and is isolated from the outer frame structure by the grommets 59 surrounding the head ends of the bolts 58. As a consequence the transmission of noise or vibration in either direction through the window is materially reduced. i
It will also be noted that the various components of the window construction may be rapidly disassembled; and inasmuch as the inner window frame structure comprising the two substructures, which carry the weatherside and roomside windowpanes, is installed as a unit, this assembly may take place at a factory rather than at the point of use, and may be accomplished at a minimum of expense and time. Such factory assembly also ensures a hermetically sealed compartment between the two windowpanes.
Reference is now directed to FIGURE 5, which illustrates a modified formof the window construction adapted as a triple-pane window. The construction is the same as that shown in the first described structure, except that the frame members 22 and 42 are separated to provide space for a center window frame member 76.
The center Window frame member 76 is channel-shaped and provided with flanges 77, similar to the confronting flanges 65 of the frame members 22 and 42. The frame members 22, 76 and 42 are connected in series by a pair of isolating members 67 held in the retaining channels 71.
The center window frame member 76 is provided with a fixed stop iiange 78, corresponding to the flanges 32 and 48, and a removable stop flange 79 secured to the frame member 76 by screws. The stop flanges deiine a channel which receives a window S0 which rests on the mounting blocks 37 in the manner of the windowpanes 36 and 49. Gasket strips 33 center the pane between the iianges 7S and 79. In this construction two acoustical pans 81 are used which are similar to the acoustical pan 72 except that they have less width.
Reference is now directed to FIGURE 6. In this construction, the double window arrangement shown in FIGURE l is utilized without change except that the acoustical pan 72 is omitted, and, instead, two window frame members 82 are provided. Each window frame member 82 includes a channel-shaped stop S3 from which extends a lateral shelf 84 terminating in a latch bead 85.
Fitted over the shelf is a channel-shaped retainer member 86 having a latching means 87 which cooperates with the latch bead SS. The retainer member 86 includes a lateral lip 88 which extends toward the channel stop 83 and forms therewith an inwardly open channel having a cushion 89 which receives a windowpane 96.
The two window frame assemblies are mounted between the gasket strips 33 and the excess space is lled with separator strips 91, of rubber or other elastomer.
It will be noted that if only three panes are required, one of the central windowpane units may be omitted and -an acoustical pan of appropriate width substituted.
