3 Claims.
This invention relates to window sash constructions, and has for its object a window construction, which consists merely of a frame suitably recessed or channeled for receiving-aglass pane and a glazing strip-of resilient lcompressible material, which is readily applied and also intentionally removable but held from unintentional displacement.
The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawing in whichlike characters designate corresponding parts in all the views.
Figure 1 is an isometric View of the comerportion of a sash embodying this invention.
Figure 2 is a transverse fragmentary sectional ily replaceable, when broken. The glass pane is mounted against-a resilient backing and held in position by resilient compressible glazing strips which are capable of being placed in position or being pressed into positionan inch or so at a time and also are capable of being quickly-pulledout of position for the purpose of replacing a broken pane. Glazing strips of this type have heretofore been firmly interlocked with the sash frame or some other part-associated therewith. The interlocking requires skill or care on the part of the workman.
One of the objects of this invention-is a Window construction embodying a resilient compressibleglazing strip in which no interlockingof the strip and the window sash or associated parts against edgewise displacement is employed but at the same time'the strip is held from" unintentional outward sh-ifting or displacement.
The feature of theinventio-n is-a compressible retaining or glazing strip provided with means by which a displacing movement out of the glazing strip grooveor channel wedges, without interlockingmeans, the glazing-stripmore firmly in the glazing strip groove or channel but permits the intentional displacing upon sufficient pulling force being applied, such pulling force, when once started, tending to stretch the glazing strip, which is elastic, and hence tending to release the wedging means.
The window sashes are usually formed with rounding corners, and the glazing strip has a greatrtendency to loop out of the glazing: strip groove at the rounding corners.
InFigure 1, l designates a sash frame formed up of sheet metal tohave one sidehigher than the other, the hi-gherside being formed with a'rabbet 2 for receiving the margin of the glass pane 3 and an interposed resilient backing strip 4. The
frame'is also formed up to have a retaining or glazing strip groove or channel 5 located beyond the bottom of the rabbet Z and the edge of the angular or L-shaped in cross section with one flange thereof backing against the inner face of the higher wall -ofthesash frame and the other flange-thereof seating on'thebot-tom' of the rabbet 2. The glass pane presses against the back ingstrip and may also press'at its edge against the portion "of the backing 'strip on the bottom of the rabbet.
fi designates the 'r'etaining'or glazingstrip, this bei'ng of a-resilientcompressible and somewhat elastic" material; as'some form o'frubber. It is usually formed by an extruding operation. It includes a base portion 1 and a head portion 8; the base portion 1 being rectangular in cross section'to fit in between theparallel sides of the groove 5' and owing to the parallel sides of the rectangular formation is readily compressed into the groove without the exercise of much care or skill. Itis formed onat'lea'st oneside thereof with-one or more inclined projections inclined toward' the entrance of the groove ,5 in order to flattenwithout"resistancetoward the body of the base 1 when the base 'lis-being compressed into-'thegroove 5-" andto spread outwardly or straighten to in effect increase the Widthwise direction of the base I,v and hence" wedge the base in thegroove; whenthe glazing strip is subjectto force tendingto-shiflt it or" cause it to creep out of the-groove- 5'.-
9- des'ignates the projections," which are in the form of barbs in cross Section. In Figure 1, they are shown as engaging the inner wall of the groove 5. The head 8 is provided with a shoulder at l0 thrusting on the edge of the lower wall of the sash frame. The strip before being applied is of the form shown in Figure 3, and hence distorts and is under tension, when placed in the sash frame, as shown in Figure 1. The backing strip 4 is first applied to the rabbet in the sash frame and may be secured thereto as by an adhesive. The glass pane is then placed against the backing, and then the glazing strip pressed, starting at one end or at any point and inching the base portion thereof into the groove 5. During this operation, the barbs 9 fold'down against the body of the base portion, permitting the base portion to slip comparatively easily be'- tween the parallel sides of the groove 5. During this pressing or inching operation, the base portion is also compressed and then when the com.- pression is released, the base portion reacts against the parallel side walls of the groove 5 with sufficient friction to hold it from displacement. However, if the strip is subject to a force tending to displace the base portion out of the groove, the barbs tend to straighten and more firmly wedge the glazing strip in the groove. In removing the glazing strip, it or one end of it is started out of the groove, and then a pulling force applied tending to stretch the glazing strip, the pulling or stretching tending to contract the glazing strip in a widthwise direction, and hence releases its frictional wedging contact with the walls of the groove 5. Thus, the glazing strip can be readily applied and removed without providing any construction or meansfor interlocking with the sash frame.
In Figure 2, the sash frame is shown in the cross sectional form of a rectangular channel, with one side higher than the other, and the backing strip H is shown as having a base portion i2 fitting the channel beyond the edge of the glass pane !3 but being of less width than the,
channel, so that one face thereof is opposed to the lower wall, M of the sash frame, providing the glazingstrip groove !5. ,However, both sides of the groove are paral1el, and thebase portion of the glazing strip formed with barbs 16 coacting with the wall of the grooveformed by the base l2 of the backing strip H. V
In Figure 4, ,thebarbs l6 are shown as provided on one wall of the glazing strip groove and specifically on the base portion l2 of the backing strip H. ;Also, in Figure 4, barbs H are shown on the base portion of the glazing strip and coacting with the inner face of the side of the sash frame forming the wall of less height of the sash frame.
In any form of the invention, the barbs compress, When the strip is being compressed into the glazing strip groove and tend to expand into a straight line or exert a greater outward pressure upon shiftin movement of the glazing strip out of the glazing strip groove, and this wedging action or frictional engagement is relieved to a large extent, when the glazing strip is being removed by pulling on it. When the sash is in normal use, there are no conditions tending to apply the stretching force to the glazing strip, or, in other words, the tensioning force must be intentionally applied,
In the constructions shown in Figures 1 and 2,
the frame I and the backing strip 4 or II constitute a unit, and this unit is provided with a groove having sides parallel to the plane-of the glass for receiving the base portion of a retaining or glazing strip, which base portion is provided with barbs to restrain the working of the retaining or glazing strip or the base thereof out of the groove. In the form shown in Figure 1, this groove is formed wholly in the frame itself. In the form shown in Figure 2, the groove is formed between the parts of the unit consisting of the backing strip and the frame. The feature of both is the barbs or their equivalent tending to expand and frictionally hold the retaining or glazing strip from working out of the groove. The barbs also facilitate the placing of the glazing strip into the glazing strip groove, as they fold or flatten against the body of the strip when the strip is being pressed intothe groove. The strips, which are formed by an extruding process, vary in width slightly and also the grooves vary. The barbs compensate for variations in the strips and in the grooves.
What I claim is: 1. In a window sash construction comprising a frame provided with means for forming a glass receiving rabbet open at one side and arranged with a groove located beyond the edge of the glass pane and out of the plane thereof, the groove having substantially parallel smooth sides, and a glazing strip of elastic resilient compressible materlal having a base portion formed with parallel sides compressible in the groove, and a head portion of greater width than the base portion and normally projecting beyond the plane of the side of the base portion toward the glass pane and pressing against the glass pane, whereby the head portion is under compression in a direction trans-,
versely of the base portion when compressed against the glass pane, andhence tends to pull the base portion out of the groove, the combination of said sash construction having means limiting the lateral movement of the head portion under the transverse compression force,,and of the base portion of the glazing strip having means tending to expand in a widthwise direction against the walls of the groove and to grip the same under the transverse compression action of the glass pane on the head portion and tighten the base portion in the groove against outward displacement.
2. In a window sash construction comprising a frame providedwith means for forming a glass receiving rabbet open at one side and arranged with a groove located beyond the edge of the glass pane and out of the plane thereof, the groove havingsubstantially parallel smooth sides,
and a glazing stripof elastic resilient compressible material having a base portion formed with parallel sides compressible in the groove, and a head portion of greater width than the base portion and normally projecting beyond the plane of the side of the base; portion toward the glass pane and pressing against the glass pane, whereby the head portion is under compression in a direction transversely of the base portion when compressed against the glass pane, and hence tends to pull the base portion out of the groove, the combination of said sashconstruction having a shoulder at the edge of the outer side wall of the groove on which the head portion presses, saic. shoulder limiting lateral movementofthe :head portion under the transverse compression force, and of said-base portion having means tending to expand in a widthwise direction against the side walls of the groove and to grip the same under the transverse-compression action of the glass pane on the head portion and tighten the base portion in the groove against outward displacement.
