3,128,510 SASH MOUNTING Dominick C. Fanello, Mansfield, and George N. Ratio, Ashlanti, ()hio, assignors to Shiloh Tool & Die Mfg. Company, Mansfield, Ohio, a corporation of Ohio Filed May 23, 1961, Ser. No. 112,096 8 Claims. ((11. 2052.2)
This invention relates to a window construction and, more particularly, to such a construction having sliding sash members.
In conventional wooden frame and sliding sash windows, each sash member slides up and down in its own longitudinal channel within the frame. Such a construction presents the problem of difficult cleaning and window repair or glass replacement, since the sash members cannot be removed without dismantling part of the window or frame. Although various types of window constructions have been proposed which alleviate these difiiculties to some extent, none has been accepted by the public to any great degree for one or more reasons. Further, since the wooden frame sliding sash construction has been prevalent in residential housing for many years, a substantial number and variety of window appliances and accessories such as fans, air-conditioners, louvered panels, screens, etc., have been manufactured and are owned by the public which are not readily adapted to some of the more modern types of window constructions.
It is therefore an object of this invention to provide a mounting for sliding sash windows wherein the sash members are readily separable for ease of installation, cleaning and repair.
Another object of this invention is to provide such a construction wherein the basic configuration of the conventional double sash construction is unchanged so that ordinary window appliances may be utilized therein.
A further object of this invention is to provide such a window construction wherein a sash slides in at least one stop which is retractable without the necessity of the user applying pressure to retract the stop.
A still further object is to provide such a construction wherein the tension of the sash cord is utilized to retract at least one of the stops when and if desired.
Other objects and advantages of the present invention will become apparent as the following description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of the various ways in which the principle of the invention may be employed.
In said annexed drawings:
FIG. 1 is an isometric view of a double hung sash window incorporating the features of this invention;
FIG. 2 is a partial elevation view of a corner of one of the sashes showing the sash cord engagement therewith;
FIG. 3 is an end view of the illustration shown in FIG. 2;
FIG. 4 is an enlarged and broken view taken substantially in the plane of the line 4-4 in PEG. 1 and thereby showing a cross-section of the window members;
FIG. 5 is an isometric view of a latch cam according to this invention;
FIG. 6 is an elevational view of a retractable stop according to this invention;
FIG. 7 is a longitudinal sectional view of the stop of FIG. 6, parts being broken away;
FIG. 8 is a fragmentary view of a portion of the FIG. 7 stop in similar section; and
FIG. 9 is a further fragmentary view of the FIG. 8 assembly in another condition of adjustment of the same.
Referring now to FIGS. 1 through 4, a window construction is shown having right and left side frame members 1 and 2, bottom frame member 1a and inner and outer sashes 3 and 4. Both side frame members 1 and 2 have sheet metal facings 5 and 5a running vertically their entire height and serving as weather seals. The left frame member 2 is provided with two retractable, channel-shaped longitudinal stops 6, the open sides of which are disposed in outwardly open longitudinal recesses 7 formed in the facing 5. These stops are adapted normally to protrude from the facing 5 into longitudinal grooves 8 in the adjacent sides of sashes 3 and 4 for guiding of the latter. The right frame member 1 may have an identical construction; however, it is preferable as shown to utilize a sheet metal facing 5a having nonretractable stops 6a, which may be integrally formed, protruding therefrom in opposition to the retractable stops 6 and similarly engaged in side grooves of the two sashes 3 and 4.
Each sash 3 and 4 at the bottom of each of its two side grooves 8 has a recess 9 wherein a downwardly directed hook 10 is located. As can be seen best in FIGS. 2 and 3, this hook engages a ring 11 on a sash cord 12; just above the hook are a pair of guides 35 which hold the upper part of the ring 11 away from the recess 9 for a reason to be explained. The configuration of the hook is immaterial as long as it permits the ring to be readily detached by the cord arresting mechanism, to be discussed hereinafter, and also easily removes such ring from said mechanism in a manner to be explained.
The sash cord is tensioned in the manner shown in FIG. 7 to counterbalance the sash by means of spring 13, fixed at one end to the inside of stop 6; the other end of the spring is connected to a pulley or block and tackle assembly comprising a movable, rotatable pulley 14 and a pulley 15 which rotates on a pin connected to the stop. The sash cord 12, preferably of strong, relatively fine nylon twine, is connected to the stop by pin 16 and passes around pulleys 14 and 15 (preferably twice around each, producing a mechanical advantage of four) and then passes out through the stop at opening 17. The sash cord has ring 11 connected at its free end which is larger than the opening 17 thus preventing the end of the cord from being lost within the stop. The exterior surface of the stop below the opening 17 has a shallow depression as shown which permits the sash cord 12 (and its knot on the ring 11) to pass freely without abrasion. Although the above described tensioning means is preferred for the purposes of this invention, it could be replaced by other mechanisms and even the old, conventional weighted cord and pulley arrangement. The same tensioning means described is used in the non-retractable stop as well.
The retractable stop 6 is also shown to be equipped with a pair of toggle cams 18 which are pivotally connected to the stop by pins 19 and also pivotally connected to the hollow channel 7 of the metal facing 5 by pins 24). The cams 18 have fiat surfaces 21 to engage the inside of the hollow channel 7 when the stop is extended thereby to back and support the same. When the sash cords from the stops on both sides of the sash engage the hooks thereon, the sash is hung and counterbalanced properly.
The retractable stop 6 also contains near its bottom a latch cam 22 shown in FIGS. 5 through 9 which operates both as a sash cord arresting means in one position, shown in FIGS. 8 and 9, and a cam to hold the lower portion of the stop 6 away from the hollow channel 7 in another position, shown in FIGS. 6 and 7. The latch cam 22 is pivotally connected to the stop 6 by pin 23 and also engages pin 24, which is connected to the hollow channel 7, through the slot25. In the position shown in FIG. 7, the camming surface 26 bears against the fixed channel surface 7, and the cord arresting portions, arms 27, are retracted within the surface of the stop 6. The latch cam 22 is releasably held in this position by tensioning means which comprises a spring 28 connected and held at one end to pin 23 and connected at its other end to pin 29. As the latch cam 22 is pivoted, the pin 29 in slot 39 rides over flattened nose surface 31 of the cam.
The non-retr actable stops of the sheet metal facing 5a in frame member 1 are also equipped with latch members 22a which are similar to the latch cam 22 and thus also have cord arresting means similar to arms 27 which can be projected from, or retracted Within the stop surface; obviously, such a member 22a need not have a camming surface 26 since the associated stop 6a is non-retractable and is rigidly held in a projected position. Such latch members 22a preferably will have tensioning means 23a (similar to the spring 28 and pins 23 and 25 of latch cam 22) to releasably hold them either in the retracted or projected positions.
To remove a sash from the window construction as described above, one first of all manually projects the cord arresting means (arms 27) of the latch cams 22 and 22a which are at the same elevation at the sides of the sash, with the latter moved above the cams. This may be done by pulling on the arms 27 by hand or with a simple available implement. The sash is then lowered until its hooks It with the sash cord rings 11 thereon are just below the arms 27. It should be noted that in pas ing downward to arrive in that position, the hooks 1i and rings 11 press the arms 27 of latch cams 22 and 22a downward somewhat but not enough to shift their flattened nose surfaces 31 below pins 29 into retracted position.
After reaching the position shown in FIG. 8, the sash is raised; the arms 27 then engage the rings 11 removing them from the hooks 10. The tension in the sash cords 12 is then transferred from the sash to the stops through the cord arresting means. In the retractable stops 6, this is represented by the position shown in FIG. 9. When this cord is removed from the sash and placed on the stop 6, the tension tending to pull the stop 6 downward and outward by toggle cams 18 is relieved. At the same time, the tension of the cord 12 is transferred to the arms 27 of the latch cam 22 causing the latter to pivot further in the counter-clockwise direction around pin 23 as shown in FIG. 9. Since, however, the latch cam 22 is also connected to the hollow channel 7 by means of pin 24, this rotational action causes the latch cam 22 to act as a lever arm pulling the whole stop 6 within the hollow channel 7. The earns 18, of course, follow the same movement. The pin 24 goes into slots 32 in the stop 6 to enable full retraction of the stop within the channel; slots 33 are provided near the toggle cams 18 to receive pins 20 in the same manner.
Since the retractable stop 6 is now withdrawn from one groove 8 of the sash and both sash cords are detached therefrom, the sash may be easily removed by pulling out its side adjacent the retracted stop, pivoting it along its side engaged with the non-retractable stop 6a.
To replace the sash, one side (in this case, the right side) is placed against the protruding, non-retractable stop 6a engaging the groove 8 of the sash on the right side. The sash is then pivoted along the right side swinging the left side into place with the groove 8 along the left side in alignment with the retracted stop 6. The sash member is then lowered to the point where the hooks llll engage the sash cord rings 11 removing them from the arms 27 of the latch earns 22 and 22a. The recesses 9 of the sash each have a curved camming surface 34 which, as the sash is lowered even further, bear upon the tops of the arms 27 of the cord arresting means sufiiciently to cause the latter to be pushed within the stops (sliding the flattened nose surface 31 below pin 29) where they are releasably held in their retracted position as shown in FIG. 7. In this latter position, the camming surface 26 of the latch cam 22 will force the lower part of the retractable stop 6 to be projected and with the tension of the sash cord 12 now again being applied, the toggle cams 13 will force and hold the upper part of the stop 6 in the projected position as well. With the stops 6 in this position and the arms of the cord engaging means on all stops retracted, the sash will function in a normal manner, i.e., they will be properly counterbalanced for easy raising, lowering and positioning and, further, will be sealed against weather by their engagement with the stops on each side.
It will, of course, be clearly understood that both sashes in the illustrated double-hung window construction are operative and can be handled in the same manner.
It can be seen that this invention permits sashes for conventional style to be quickly and easily removed for cleaning and repair without the need of special tools or techniques and with a minimum of physical effort. In addition, this invention greatly simplifies the construction and assembly of windows and their counterbalancing mechanisms.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims or the equivalent of such be employed.
We therefore, particularly point out and distinctly claim as our invention:
