4 Claims. (Cl. 2048) This invention relates to improvements in doublehung windows and appertains particularly to such windows designed for combined vertical sliding and inward swinging movements.
An object of the invention is to provide a sliding and hinging double-hung window structure suitable for manufacture of wood or metal and that is neat and compact; allows of double glazing; is readily installable in place of the usual sashes such as are operated by springs, weights and pulleys, or other types of sash balances; and in which standard type weather stripping may be used between the window and frame.
A further object of the invention is to provide a sliding and hinging double-hung window in which the stiles of each sash are made in two parts, hinged together at the bottom for lateral separation and interlocking at their junction in a weather-proof joint, sothat the sash proper may be hinged inwards while the outer parts of the side stiles remain vertical.
A further object of the invention is the provision of a sliding and hinging double-hung window in which the sash has a two part stile hingedly connected at the bottom and wherein a novel and normally concealed stile lock recessed in the top of the outer stile part falls gravitationally to one side or the other to alternatively lock the sash against lateral hinging on the stile against raising relative to the frame.
A still further object of the invention is the provision of an improved double-hung window of the nature and for the purpose set forth that will allow the glazed sash to be hinged inwards so that the outside of the window can be cleaned from the interior of the building where it is horizontally supported at the convenient height of the sill, without interfering with exterior fixed screens and being capable of manufacture at reasonable cost is'thereby rendered commercially desirable.
To the accomplishment of these'and related objects as shall become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.
The invention will be best understood and can be more clearly described when reference is had to the drawings forming a part of this disclosure wherein like characters indicate like parts throughout the several views.
In the drawings: 1
Figure 1 is an inside elevation of a preferred embodiment of the instant double-hung hinged window;
Figure 2 is an' enlarged transverse horizontal section,
as taken on line Z2 of Figure '1, looking in the direction indicated by the arrows;
Figure 3 is an enlarged vertical transverse section, as taken on the line 3-3 of Figure 1, but with the top sash lowered and the lower sashhinged inwards;
Figure 4 is a perspective view of the special stile lock;
Figure 5 is a composite vertical, transverse section of 2,745,148 Patented May 15, 1956 this invention with the sash and frame constructed of metal; and
Figure 6 is a horizontal transverse section.
The present combined sliding and hinging double-hung window structure is hardly discernable from the usual nonhinging type, having no exposed or projecting hinges, locks or extraneous fittings; the novel stile lock engageable with either the hinging sash part or the guide channel of the frame, the straight bar hinges connecting the sash sections, and the support arms for the opened sash panels being all flush recessed and concealed.
.The window here shown has a frame 1 set in the usual window opening consisting of a sill 2, header 3 and opposite side jambs 4, the side panels and header having laterally spaced strips 5 defining the edges of the guide channels. It will be noted, however, that the outer guide channel in the side jambs 4, i. e., the one for the upper sliding sash, is stepped inwardly as at 4a in Figure 2. A lower sliding sash 6 and upper sliding sash 7 are mounted in the frame 1, the latter sash being a little narrower on account of the inward stepping of the frame guide channel.
Each sash consists of a spaced pair of side stiles 8 slidable in the guide channels of the frame 1 and an intermediate glazed panel section 9 consisting of the usual top, bottom and side rails and 2. contained pane of glass. The intermediate glazed panel or section 9 is hingedly connected at the bottom to its opposite pair of side stiles 8 by a straight bar hinge 10 whose attaching plates are recessed in confronting faces of the stile and sash and secured as by the wood screws 10b. A stepped weather-proof joint 11 occurs along the engaging edges of the hinging sash panel 9 and the stiles 8.
When the sash panel is hinged inwards, the stiles remain vertical in the frame guide channels and hold the sash panel in a horizontal position by support arms 12 each consisting of a pair of pivotally attached metal straps 12a and 12b, the upper and outer of which pivotally connects by its free end to the stile and the inner one to the sash panel; the former will preferably have an elongated slot 12c at its pivotal anchor to allow of limited sliding and the two piece arm 12 when folded, will lie in an accommodating shallow vertically elongated notch 13 in the stile 8, or confronting companion notches may be formed in both the stile and sash.
A special locking device hereinbefore referred to is accommodated in a vertically disposed trough extending across the top of each stile 8 from side to side and preferably near the front. Here shown clearly in Figure 4, a relatively thin flat lock plate 14 of unusual contour is pivotally mounted on a transverse pin 15 in an open ended U-shaped pocket 16 the opposite arms of which are flanged outwardly and secured to the top of the stile with their upper surfaces flush therewith. Another channel-like pocket 17, with arms similarly flanged, is mounted flush in a vertical trough in the top of the sash panel 9 at each of the opposite side edges thereof, such pockets being normally aligned with an opening toward the lock pocket in the stile for communication therewith and proportioned to receive the lock plate 14 when nested therein so that the upper side of said lock plate is flush with the top of said pocket 17 and projecting just beyond the inner end of the pocket 17 where a thumb notch 18 is provided as a continuation of the trough to enable a grip of the lock to be obtained for releasing the same. Another lock plate-receiving pocket 19 in the form of a rectangular mortise-type housing is set flush in a recessed seat in each guide channel of the frame at a level just above the top of the sashes when in pre-arranged lowered position, such as seen in Figure 4. The pocket housing has a face plate 20 projecting as an attaching flange at top and bottom by which it is secured in the sash guide in the jamb and is provided centrally with a vertically elongated slot affording access to its interior and with which the lock plate pocket16 can be brought into aligned registry. The lock plate 14 when in normal sash-locking position has a fiat top from which the underside of the free end recedes at a sharp angle to provide a lip that extends in re thumb notch 18 while its other or pivoted end dot, .n s outwardly at about 45- affording projection of the lock plate into the housing 19 in which it stands at rest in vertical position so that a slight raising of the sash, and stile, acts to trap the sharp pointed lip on the free end of the lock plate in the housing behind the top of the slot in the front plate while the lowering of the stile frees such trapped end and then causes the lock plate to be thrown clear of the frame pocket as the inclined lower end with the 45 bevel engages the bottom of the front plate slot.
in Figures 5 and 6, the same invention is shown incorporated in a metal window structure consisting generally of double-hung lower and upper metal sashes 6n and 7a sliding in a metal frame assembly comprisi sill 2n, headerfia and side jambs 4a. Each sliding window section similarly has an opposite pair of stile posts tin and an intermediate sash panel section 9:: hingedly con nected at the bottom by hinges 30x. The same type of novel lock plate 14x is likewise mounted in the top of the stiles for locking the glazed sash against inward hinging or may be swung through 90 into the housing 192: in the guide channel of the jamb and the same kind of hinged support arms 12x are provided to h id the inwardly hinged sash panels in horizontal position for cleaning.
This metal window is preferably constructed of L, durable, non-ferrous or at least non-corroding material such as aluminum, brass, bronze or the like. The frame parts are each shown as composed of inner and outer members with a fibre strip 21 at the juncture of the complementary frame parts across the top and down the jambs serving as a spacer between the guide channels for upper and lower sashes, and a fibre inseit 22 in the sill between upturned flanges of the companion sill parts that is straddled by the bottom cross rail of the lower sash 6:1.
in the composite sliding sashes, the stile posts 3:! are of solid form with an offset forwardly facing lip 8b to provide a weather-proof joint for overlapping engagement with a similarly configurated but oppositely facing offset lip 9b on the outer sides of the hinge-able sash panels 9a which may be of extruded form with an open or hollow core 90. The edge of the glazed rectangular opening defined by the sash has a double stepped shoulder 90' for the reception of a double glazing member 9, that carries one pane 9g in a groove in its outer deeper side and compresses the other pane N1 between its inner face and the outer face of the inner shoulder of the sash. Screws 23 are employed to hold the fibre strips to the frame parts and also in connecting the glazing members 9 to the sash panels 9:: while between the channel-dividing fibre strips 21 and the frame and/or the stile posts or sashes and also between the double glazing member 9f and both the inner pane 9h an the sash 9a respectively, recess-carried felt strips 24 are employed for insulation and vibration dampening.
In use, these combined sliding and hinging doublehung windows, constructed of either wood or metal will be found most convenient, since they permit of the permanent installation of outside screens besides afiording such easy access to the outside surface of the windows for washing. To hinge the glazed panel section of the sash inwards, as for washing, the lower sash is raised to clear the sill, the stile lock is released, and swung through approximately 90 into the jamb pocket housing with which it will be or should be brought into substantial registry and the glazed or inner sash panel is then hinged inwards until supported in horizontal position by the support arms at the side. The upper sash should be lowered to a point slightly above the lower sash so that it may be hinged into a superposed horizontalposition spaced just a little above the lower sash, in which, po-
sition the stile lock of the upper sash should be in horizontal registry wit-h its-jamb lock housing. To enable the glazed panel of the upper sash to swing inwards through the space between the stile posts of the lower sash into such superposed horizontal position as described, the stile posts of the upper sash are either thicker or the guide channel is inwardly offset so that the glazed panel section of the upper sash is narrower than the spacing of the stile of the lower sash.
From the foregoing description taken in connection with the accompanying drawings, it .will be manifest that a double-hung window is provided that will fulfill all the necessary requirements-of such a device, but as many changes could be made in the above description and many apparently widely different embodiments of the invention may be constructed within the scope of the appended claims, without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and'drawings shall be interpreted as illustrative and not in a limitative or restrictive sense.
