4 Claims. (Cl. 2li-53) This invention relates to windows and more particularly to windows combining stationary and complementary movable frames.

The principal object if the invention is to prolide a window comprising a stationary frame fabricated preferably of extruded sections, within which is mounted for opening and closing movement a second frame which embraces a third frame which is pivoted or otherwise connected to the assembly composed of the stationary and second frames to facilitate cleaning of the window from inside of a building and for more etiicient weathering.

Another object of the invention is to provide a window construction which, by virtue of the multiple frame arrangement, makes possible unbroken perimeter weatherstripping to positively insure against infiltration of fine dust particles and moisture when closed and to provide natural ventilation when in open position.

Another object of the invention is to provide a window whose unusual frame assembly is of such design and construction that the window may be installed for either inward or outward swinging displacement of its movable auxiliary frames and in the case of the latter, venetian blinds, curtains or other window hangings will not be disturbed nor will structural columes interfere with proper manipulation of the swinging frames.

Broadly, the invention anticipates two forms of window construction, each having certain characteristics in common with the other. The first form of the invention consists of a stationary frame to the top of which is hinged a second and auxiliary frame and within the second frame is pivoted along its vertical axis a third frame which contains the glazing. In this form of the invention the perimetrically continuous weather seal is ailixed in vthe stationary frame. In the other form of the invention, the stationary frame has'pivoted along its vertical axis a second and auxiliary frame which carries the glazing and a third frame to which is ailixed the unbroken perimeter weather stripping or seal. In both forms of the invention, the weather stripping positively seals the space between the side and top edges of the stationary frame and the second movable frame.

Other objects will appear as the description proceeds when considered with the annexed drawing, wherein:

Figure 9 is a fragmentary sectional view taken on line 9 9 of Figure 8, and

Figure 10 is a perspective View, on a reduced scale, showing the second and third frames in open position.

Continuing with a more detailed description of the drawings, reference is made primarily to Figures 1 to 4 in which numeral 10 denotes generally the main or stationary frame; 11, the second frame and 12, the third frame. The rst or stationary frame 10 is preferably formed of extruded aluminum to dene outer and inner anges 13 and 14, respectively, it being understood that these anges may become reversed if the frame 10 is positioned to permit the frames 11 and 12 to swing outwardly. The flanges 13 and 14 are continuous about the' frame 10, being mitered at the corners thereof and are interconnected by webs 16 and 17, which form, respectively, the top and bottom portions of the frame 10 and by webs 13 forming portions of the sides thereof.

The iianges 13 and 14 form portions of the inner and outer facings of the frame 10 and continuations 19 of the flanges 13 extend inwardly of the webs 16, 17 and 13 in confronting relationship where the extrusion defines a channel 20 along the bottom, top and sides within the coniines of the outer facing of the frame I0 and opening toward the inside of the window.

Arranged conformably in the channel 20, made continuous by the joining together of the identical top, bottom and side extrusions is a weather seal 21 of tubular and compressible material such as felt impregnated rubber or the like. Further reference to the seal or weather stripping 21 will be made presently.

Formed integrally with the inner ange 14 is a right angular portion 22 from the midsection of which protrudes a flange 23 parallel with but set inwardly of the flange or facing 14. The ange 23 which forms a part of the top of the frame is provided with spaced apart slots 24 through vwhich extend the plates 25 of hinges 26, the companion plates 27 of the hinges being aixed to the top flange 28 of the second frame 11.

The second frame 11 is of the same profile in transverse section taken at any point along its top, bottom or sides. A box-like channel 29 having inturned, confronting edges 30 is formed integrally with the ilange 28 of theframe 11 and is of rectangular shape in transverse section. This channel is disposed at right angles to the plane of the an'g'e 28 and extends inwardly of the stationary frame 10 is closed position of the second frame 11 and bears against the outer half of the weatherstripping 21, the other half thereof being engagedy by a correspondingly shaped channel 31 which constitutes the third frame 12 and which has inturned confronting edges 32 defining a longitudinally lcocxtensive opening 33 along its sides, top and bottom which confronts alike opening 34 in the channel 29 of the second frame 11 defined by the inturned ends Sil of this channel.

Fixed midway between the ends of the top channels 29 of theframe 11 is a bearing block 35 and installed similarly in the bottom channel 29 thereof is a correspondingly shaped bearing block 36. A bushing 37 is disposed in a hole 38 (Figure 2) extending through the center of the bearingv block 37 and mounted in the bushing 37 is an end of a pivot pin 39 whose opposite end is anchored in the bearing block '40, afx'ed in the chan`- nel 31 of the frame 12 at its mids'ection. In axial alignment with the pivot pin 39, a similar pin 41 is aixed in the lower bearing block 40 of the frame 12 and has its opposite end journaled in a bushing 42 of the lower bearing block 36 of the second frame 11. A pair of friction washers 43 are interposed between the bearing blocks 35 and 40 of the frames 11 and 12, respectively, at both the tops and bottoms thereof.

The innermost or third frame 12 has a glazing channel 4S formed about its inner faces dened by a tlange 46 on one side and a removable retainer strip 47 on the opposite side, the strip 47 being formed with a longitudinally coextensive wedge 48 which bears: against the web of the channel 45. The strip 47 is held in position by a Z-joint 49 formed jointly in the meeting edges of the channel 31 and the strip 47 entirely around the perimeter of the frame 12. i

The inner edges of the tiange i6 of the channel 45 and of the strip 47 are turned confrontingly inward to retain the glazing material 50 which holds the edges of the glass panes S1 in their respective channels 4S. The panes in this case being of the thermal type, that is, parallel panes defining an air space 52 therebetween.

It is clearly evident from the foregoing that a positive and continuous Weather strip is provided to seal the space between the juxtaposed edges of the second or intermediate frame 11 and the innermost or third frame 12, When these frames are closed as shown in Figure 1, the inner surface of channel 29 of the frame 11 bears against the weather-strip 21 as does the channel 31 of the inner frame 12. A stop 53 is provided for the lower tlange 2S of the frame 11 in the form of a longitudinally coextensive rail formed integrally with the frame 1t) and against which the ange 28 bears in closed position of the frame 11.

In order that the glass 51 of the window may be washed, both frames 11 and 12 are swung away from the stationary frame on the hinges 26 to the position shown in Figures 2 and 4, each of which reveals the frame 12 as having been rotated 90 with respect to the frame 12. It is clear that when the frames 11 and 12 are in the extended position shown, the frame 12 can be rotated 360. After cleaning both sides of the glass 51 by revolving the frame 12 on its pivots 39 and 41, the frame 12 is restored to parallelism with the frame 11 and both frames are swung back into the stationary frame 10.

When in extended position, the frames 11 and 12 are supported by a pair of stay arms 54 (Figure 4) which lock automatically when the frames are moved to maximum extended position. It is obvious that these arms can be constructed so that the frames 11 and 12 may be supported at any desired angle between fully open and fully closed positions, if desired.

Referring now to the modified form of the invention shown in Figures 5 to l0; numeral 60 generally indicates the stationary frame; 61, the second or intermediate frame and 62, the innermost or third frame. In this form of the invention, the second frame 61 is adapted to revolve about an axis extending vertically through the midsection of the frame 60 and the third frame 62 is hinged at its top to the top of the stationary frame. The intermediate frame carries the glass while the third frame carries the unbroken perimeter weather stripping.

The stationary frame 60 is formed with anges 63 and 64 which extend entirely around the window to form the header, jambs and sill, each being cut from the same extruded body and mortised at the corners in the usual manner. The flanges 63 and 64 are interconnected by a web 65 and spaced inwardly of the web is a channel 66 which coincides with a correspondingly shaped channel 67 constituting the body of the frame 61, it being understood that the channels 66 and 67 are of the same form in transverse section taken at any point through the sides, top or bottom of the window, as revealed in Figures 6 to 9. The channel 66 of the trarne 60 has inturned confronting edges 68 and within the channels 66 forming the top and bottom members of the frame 60 are vertically aligned bearing blocks 69, each having a bushing 70 to receive a pivot pin 71 which extends through the web '72 of the channel 67 of the frame 61 and enters a recess i3 in a bearing block 74 situated intermediate the ends of the channel 67 at both the top and bottom of the frame 61. In this manner, the frame 61 is made to revolve about a vertical axis dened by the opposed pins 74 within the contines of the stationary frame 60, so that the 75 in the frame 62 may be cleaned on both sides from either the outside or inside of the building, depending on how the frame 6l) is mounted.

The channel 67 of the frame 61 is formedA with a perimetrical ange 76 which is opposed on the opposite side by a detachable retaining member 77 having a longitudinally coextensive portion 78 provided with a right angular wedge 79 whichlics flush against the inturned confronting edges 80 of the channel 67 of the frame 61. Opposite the portion 78 of the member 77, a Z-joint 81, formed jointly in the contiguous portions of the member 77 and channel 67 holds the member 77 against outward displacement to retain the glazing material 82 in which the edges or the pane 7S are embedded.

In ord-er to intercept moisture seeking to enter the space between the channels 66 and 67 of the frames 60 and 61, respectively, the outer surface of the web 72 of the channel 67 is provided with groups of longitudinally coextensive serrations 83 along which the condensed moisture is accumulated and drained ott at the bottom of the window, thus preventing it from reaching the weather stripping 84, carried by the hinged frame 62, which will now be described.

The frame 62 is composed of mortised top, bottom and side members of the same shape and transverse section and these members are each composed of a tlange S5 which extends entirely about the perimeter of the frame and extending inwardly from the flanges to embrace the channel 66 of the frame 69, in closed position of frame 62, is a skirt portion 86 on which is formed reinforcing ribs S7 coextensive with each section of the skirt, that is, its top, bottom and sides on the interior surfaces thereof.

Formed on the inner surfaces of the llanges 35 of frame 62 are channels S3 in which the continuous weather stripping S4 is disposed. The Weather stripping protrudes from the channel S8 and engages the adjacent surfaces of both the channel 67 of the frame 61 and channel 66 of the stationary frame 6i), thus closing the space between the frames 6l) and 61 to prevent infiltration of dust and moisture in closed position of the frame 62.

The frame 62 is suspended from the top of frame 60 by means of a pair of lugs 89 formed on the top portion of the skirt 86 which are apertured to receive pins 90 extending inwardly from the sides of frame 60.

In support of the frame 61 in closed position thereof, a roller 91 is disposed under each corner of the frame 61 in closed position thereof. These rollers are parallel with the bottom channel 66 of frame 66 and each roller has a spindle 92 on one end (Figure 9) journaled in the web of the channel 66 while the spindle 93 on the opposite end of the roller is supported by a bracket 94 attached to the bottom web 65 of the stationary frame 60.

From the foregoing, it will be seen that the intermediate frame 61 may be rotated in the stationary frame 60 so that both sides of the glass 75 may be cleaned from the inside of a building. Rotation of the frame 61 is possible through 360 if desired, and locked in any position by suitable conventional hardware, but only after the third or weathering frame 62 has been raised to a position above the plane through which the upper end of the frame 61 passes as it is rotated.

The frame 62 is held in raised position by stay arms 9S (Fig. l0) and held at any desired angle.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be Within the spirit and intent of the invention.
