9 Claims.
The invention relates generally to window constructions and refers more particularly to improvements in a combined sash guide and Weatherstrip for windows of the type having vertically slidable sashes.
Windows of the above general type are usually provided with a casing having vertical side frame members and having stops respectively supported on the members adjacent the inner and outer sides of the casing. In the so-called double hung windows a parting stop is ordinarily provided on the frame midway between the inner and outer stops. The parting stop projects between the two sashes and acts as a spacer for the latter.
With the above in view, it is an object of this invention to provide a combined sash guide and Weatherstrip at one side of the window casing characterized in that it yieldably urges the sashes into retaining relation to the fixed guide at the opposite side of the casing, applies force components to the sashes in directions to urge the latter into weathersealing engagement with the parting stops between the sashes, and affords sufficient lateral shifting movement of the sashes relative to the casing to release the sashes from the fixed guide and permit Withdrawal of said sashes from the casing.
Another object of this invention is to provide a one-piece strip having a channel-shaped section intermediate the opposite longitudinal edges of the strip for receiving a parting stop and having the flanges of the channel turned laterally outwardly on radii of substantial length to provide flexible wing parts which respectively extend toward the inner and outer stops on the casing between the frame members of the casing and the adjacent side edges of the sashes. The
flanges of the channel are free from attachment to the parting stop and have in effect a rolling contact with the stop upon flexing of the wing parts so as to distribute the bending stresses over a substantial area of the flanges.
Still another object of this invention is to provide a strip of the above type having outwardly opening channel-shaped sections at the free edges thereof. The outer flanges of the channelshaped sections have the terminal edges engageable with the inner faces of the inner and outer stops, and the inner corner portions of the channel-shaped edge sections respectively slidably engage in grooves formed in the sashes at the outer corners thereof. Thus both sashes are not only effectively guided by the strip but, in addition, the Wing parts of the strip yieldably urge the sashes into sealing contact with the flanges of the channel-shaped intermediate section of the strip.
A still further object of this invention is to provide a strip of the type set forth in the preceding paragraph rendering it possible to shift the sashes laterally in a direction toward the strip a sufficient distance to release the opposite side edges of the sashes from the adjacent frame member of the window casing. Thus either or both sashes may be readily inserted into and removed from the window casing.
It is a still further feature of this invention to removably secure both the strip and associated parting stop to the adjacent frame member of the casing by common fasteners which extend outwardly through openings provided in the base portion of the intermediate The foregoing as well as made more apparent as this especially when considered in connection with the accompanying drawing, wherein:
Figure 1 is a fragmentary perspective view of a combined sash guide and Weatherstrip embodying the features of this invention;
Figure 2 is a fragmentary cross-sectional view through a window of the double hung sliding sash type and embodying the combined sash guide and Weatherstrip disclosed in Figure 1;
Figure 3 is an enlarged cross-sectional view through the combined sash guide and weatherstrip, and showing the same applied to the parting stop for the window.
Referring more in detail to the drawing, the numeral Ill designates a double hung window of the sliding sash type comprising a casing II and a pair of sashes l2 and l3. The casing II has vertical Side frame members I4 and I5 constructed in accordance with conventional practice'. The inner face of the frame member I4 is covered with a guide [6 comprising an elongated one-piece metal strip having portions-at longitudinally spaced points secured to the frame member M by fastener elements'in the form of screws IT.
The guide strip ally outward opening channel-shaped section inother objects will be description proceeds termediate opposite longitudinal edges thereof and this section projects laterally inwardly with respect to the frame member [4 between the sashes l2 and [3 to provide The inner marginal edge of the guide strip I6 is formed to provide a channel-shaped stop I9 and the outer marginal edge of the guide strip [6 is formed to provide a similar stop 20. The stop l9 slidably engages in a groove 2| formed in the channel of the strip.
I6 is formed to provide a later i a parting stop l8.
adjacent portion of the sash l2 and the stop 20 slidably engages in a groove 22 formed in the adjacent portion of the sash [3. Thus, the vertical side edges of the two sashes adjacent the frame M are guided by the strip It.
The opposite vertical sides 23 and 24 respectively of the two sashes are guided for vertical movement relative to the frame l by a strip 25 which also serves as a weather seal. The strip 25 is formed from a single piece of spring metal or some equivalent material and extends for substantially the full length of the frame l5. As shown, particularly in Figure 3 of the drawing, the strip 25 is fashioned intermediate opposite longitudinal edges thereof with an outwardly opening channel-shaped section 25 having a base portion 21 and having side flanges 28. The flanges 28 are turned laterally outwardly on radii of substantial length to provide arcuate portions 29. The arcuate portions 29 are extended obliquely toward a vertical plane including the base 21 to provide wing parts 35, and the wing parts are turned laterally inwardly to form flanges 3| which extend generally parallel to the flanges 23. The flanges 31 are turned outwardly to form flanges 32 which normally lie in a common vertical plane including the base 21 of the channel 26. The extremities of the flanges 32 are turned laterally outwardly to provide flanges 33 and the terminal edges of the flanges 33 are curled laterally inwardly. It will further be noted from Figure 3 of the drawing that the flanges 33 are arcuate in cross section and have a common center of curvature.
In use, the strip 25 is mounted on the casing II adjacent the frame member 15 between the suitable stops 3-4 and 35 respectively secured to the frame member I5. As shown particularly in Figure 2 of the drawing, a parting stop 36 is removably secured to the frame member i5 midway between the stops 34 and 35. The parting stop 35 projects inwardly between adjacent sides of the two sashes and is received in the channel 36 of the strip 25. In the present instance, the strip 25 is secured to the parting stop 36 and the latter is secured to the frame l5 by common fastener elements 31. These fastener elements are in the form of screws and extend through openings formed in the base 21 of the channel 25 at points spaced longitudinally of the strip. The construction is such that the strip 25 and parting stop 36 may be attached as a unit to the frame [5.
Referring again to Figure 2 of the drawings, it will be noted that the wing parts 35 of the strip 25 are spaced laterally inwardly from the frame l5 and are also spaced laterally outwardly from the adjacent edges of the two sashes. The outer vertical corners of both sashes are formed with vertical grooves 38 providing right angle surfaces which are respectively slidably engaged by the flanges 3i and 32 on the strip 25. The terminal edges of the flanges 33 of the strip 25 respectively slidably engage the inner surfaces of the stops 34 and 35 on the frame 15.
When the various parts of the window iii are in their relative assembled positions shown in Figure 2, the wing parts 35 of the strip 25 are placed under tension by the two sashes and the terminal edges of the flanges 33 are compressed. against the adjacent stops. The construction is such that the wing parts 35 of the strip 25 yieldably urge the sashes laterally against the guide strip [6 on the frame member E5 of the casing II but, in addition, apply force components to both sashes in directions to urge the same in weathersealing contact with opposite sides of the parting stops. Any expansion or contraction of either or both sashes is automatically taken up by the flexible strip 25 so that the desired weatherseal is assured at all times. The frictional contact between the strip 25 and the adjacent sideedges of the sashes is suflicient to enable holding the sashes, in any desired position relative to the casing without the use of sash balances or equivalent devices.
The spacing between the frame l5 and adja-- cent portions of the strip 25 is at least as great and preferably somewhat greater than the depth of the grooves 2|, 22 formed in the sashes l2 and i3 respectively. As a result of this construction either or both sashes may be readily removed by merely shifting the same relative to the casing H in a direction toward the frame member I5. As a result of this shifting movement of the sashes, the wing parts 30 of the strip 25 are displaced in directions. toward the frame 55 sufliciently to release the sashes from the guide strip l6, and thereby enable the sashes to be withdrawn from the casing H. It will of couse be understood that the nature of the strip 25 also enables installing the sashes within the casing ll while the stops are in place.
Attention is directed. to the fact at this time that the flanges 28 of the channel 26. are free from direct attachment tov the parting stop 36. This is important in that, it enables thev arcuate sections 29 of the strip to roll along opposite. sides of the stop 3'6 during flexing of the wing parts 30 so that the bending stresses are distributed over a greater area of the strip and. the liability of fracture of the strip due to such bending stresses is reduced to a minimum.
