, BY M027. OEL/N %/wl Jaw Win1 arrows? May 3, 1955 M. D. ORLIN wmoow CONSTRUCTION Fil ed June 12, 1953 3 Sheets-Sheet 3 I INVEN TOR. BY Moms 0. OPL/A/ Unite This invention relates to buildings and particularly to a window construction therefor.

The primary object of this invention is to provide a multiple hung sliding sash and window opening for a wall section that is an improvement over the construction disclosed in the United States Patent No. 2,601,706, entitled Window Construction, issued to me on July 1, 1952.

Another object is to provide a window construction of the type stated for a wall section whose sash opening area may be approximately the entire area of the section, while at the same time permitting ready adjustment, removal and replacement of the sash, and permitting entire clearance of the sash opening while retaining the sash in the frame work, freely movable back to closure position.

A further object is toprovide a closure having a plurality of sashes arranged therein, one above the other, which may be easily and quickly gathered together, one in front of the other, in a magazine located at thetop of the closure, to clear the closure opening for ventilation purposes, by a simple upward movement of the lower one of the several sashes, without the necessity of handling the individual sashes, as is necessary in my aforementioned device, identified as U. S. Patent No. 2,601,706.

Another object is to provide a device of the type stated whose nested sashes, when in their open position in the magazine, may be instantly restored to their closed position by the release of a spring latch, without the necessity of touching any of the sashes at all.

Still another object is to provide a device that can be easily attached to existing constructions.

Additional objects, advantages and features of this invention reside in the construction, arrangement and combination of parts involved in the embodiment of the invention, as will appear from the following description and accompanying drawings, wherein:

Figure 1 is a front elevation of the window construction exemplifying the invention;

Figure 2 is an enlarged broken vertical sectional view taken along the line and in the direction of the arrows 2-2 of the Figure 1;

Conducive to a better understanding of this invention, it may be well to point out that in the past open porches,

rates atent 2,707,311 Patented May 3, 1955 breezeways and other area-ways have been enclosed by employing a number of so-called combination storm and screen doors assembled side by side around the periphery of the area to be sheltered. These combination structures comprise a rectangular frame having removable screened or glazed panels adapted to be interchangeably mounted thereon. The panel not being used at any particular time is separately stored apart from the frame structure. During the summer months, when the screened panels are being used, it is impossible to prevent rain and wind from entering the enclosed area during inclement weather unless the screened panels are bodily removed and replaced by the glazed ones. This is both inconvenient and time consuming. In a large enclosure the damaging effects of wind and rain will occur before all the panels can be interchanged. The self-storing feature of the glazed panels of the structure to be described permits the easy and instantaneous conversion of the closure from an open to a closed one or vice-versa.

My invention, in the preferred form shown in the drawings and briefly described hereinafter, comprises a frame 10 having jatnb and rail portions 12 and 11 respectively, joined together to define a window opening 13 as shown in the Figures 1 and 4. The frame may be fabricated from any suitable rigid and durable material and is preferably made of wood or aluminum. The width and height of the frame may be varied to suit the purpose for which it is to be used. If used in association with similar units to enclose an open porch, the dimensions of the frame are similar to that of a door.

In Figure 1 there is seen such a door-like section having mounted thereon

glazed sashes

14, 15 and 16 which are fitted into the frame opening 13 and close it against the passage of air.

Reference numeral 30 indicates a fly screen that is permanently mounted on the frame on the outer face of the window opening 13. The screen is held in place by a half-round moulding strip 39. The screen 30 may take the form of an expanded metal multi-slotted structure having a plurality of closely spaced flat slots that prevent the entrance of the direct rays of the sun as well as insects, while permitting the free passage of air and light. This type of screening is presently available commercially under the trade-name of Koolshade and provides shade for an enclosure without the use of supplementary awnings or curtains.

Reference numeral 17 indicates two facing U-shaped channels in which the

sashes

14 and 15 are free to move in a vertical direction. The upper section 1711 of the channel 17 is wider than the lower section and is demarked therefrom by a ledge 18 which supports the lower edge of the middle sash 15, as seen in Figures 2, 3, 5 and 6. The front face of the channel 17 has an inwardly extending button-like depression 19 embossed therein which extends into the plane of the channel and presses against the lower sash 14 at the point where it overlaps the middle sash 15. The size. of the button 19 is such that it will press the middle and

lower sashes

15 and 14 together to form a weather-tight seal when they are in their closed condition, as seen in Figures 1 and 2.

The lower edge of the window opening 13 is covered with a metal flashing strip 36 which is shaped on its inner face to form a vertical gutter 37, which keeps rain water from entering the enclosed area.

The metal frame of the lower sash 14 has a bracket 26 extending across it at its lower edge and along its outer face, for a purpose to be hereinafter disclosed.

An inwardly extending flange 21 which also serves as a lifting handle is positioned on the inner face of the frame of the sash 14 at a point that will enable the flange 21 to contact the top edge of the gutter 37 when the sash is in its closed position shown in the Figure 2, to

further seal the lower edge of the opening against the penetration of rain water.

The upper sash pane 16 is held in a frame 23 having a pair of laterally extending and facing side plates 22 which may be formed integral therewith or attached thereto. If made separately for attachment to the frame 23, as shown in the drawings, each side plate 22 has a rear flange 24 against which the sash frame 23 is seated and held in place by screws 25a passing through holes 25, as shown in Figures 4 and 7.

The side plates are made in pairs, there being a right hand and left hand plate associated with each frame 23. Figure 7 illustrates a right hand plate of which the left hand plate is a mirror image.

The structure just described, hereinafter called the magazine 40, is pivotally mounted at its lower edge within the window opening 13 by means of pivot pins or bolts 27 seated in holes 26 at the lower edge of each plate 22, as shown in Figures 4, 5, 6 and 7. The magazine being positioned in the opening 13 so that the upper edge of the frame 23 will fit against the upper end of the window opening. The magazine is held in place against pivoting on its pivot pins 27 by a spring lock 3s mounted in the top rail 11 and flexibly pressed against the frame 23 of the sash 16.

As seen most clearly in Figure 3, the aforementioned guide channels 17 are positioned in a plane immediately forward of the plane of the upper sash 16 and stop just short of the magazine 44 in alignment with the lower edge thereof, so that the middle and

lower sashes

15 and 14 can be slid from the channels 17 into the magazine 4t in front of the sash 16.

Each side plate 22 has a front flange 31 that rests on the front face of the frame stiles 12, as shown in Figures 1, 4, 6 and 7.

Reference numeral 32 indicates a cradle attached to each side plate flange 31, lying in the plane thereof, and extending inwardly of the magazine at approximately the center thereof.

A latch 33 made of resilient spring steel is mounted in dependent manner from each cradle 32 in the plane of the channel 17 and at right angles thereto. The lower end of the latch is bent outward toward the magazine sash 16 to form a horizontal shelf 34 and then bent inwardly upon itself to form a cam surface and finger grip 35. The length of the latch 33 being such that the cam 34 will press against the middle sash 15 at a point just below the point at which it overlaps the magazine sash 16 when the sash 15 is in its closed position as seen in Figure 2. The latch 33 is deformed at the edge of the cradle 32 so that the latch cam 35 will be constantly pressed toward the upper sash 16.

As aforementioned, reference numeral 38 indicates a lock member, of which there are two, positioned at the top of the framed opening 13, and engageable with the frame 23 of the sash 16, as is seen most clearly in Figures 1 and 4. The locks 38 are made of flat spring metal and are shaped as shown in Figure 8. Each lock 38 has a vertically extending finger 42 that may be flexed in a horizontal plane and a horizontally extending finger 41 that may be flexed in a vertical plane. When the magazine 40 is in its normally vertical, or closed position, as seen in Figure 2, the finger 41 is pressed against the inner face of the sash 16 and the finger 42 is pressed against the outer face of the sash 16, which is thus locked in position between the two

fingers

41 and 42. When the two middle and

lower sashes

15 and 14, respectively, are raised into the magazine 4t), to take the position shown in Figure 3, the top edge of sash 15 raises the finger 4'1 vertically of the sash 16 and clear of the upper edge thereof. Immediately upon the removal. of the restraining pressure of finger 41 against the inner face of sash 16, finger 42 pushes inwardly against the sash 16 to tilt the magazine 40 slightly, so that the top of the sash 16 is moved under the finger 41 as seen in Figure 3. When the sashes 1d and t5 are lowered slightly to rest upon the latch shelves 343, the finger 41 remains .on the top of the sash 16. The thus released magazine 4% may be easily swung inward by pulling on the two handles 43 to take the position illustrated in Figures 4 and 5. The magazine 40 may be relocked in its vertical position by merely pushing it against the flexible finger 42 until the linger 41 rides over the top of the sash 16, clear of same, and snaps against the inner face thereof as explained hereinabove.

The structure illustrated in Figures 1 and 2 shows the window with sashes in their closed position. The lower sash .14 is seated between guide channels 17 and rests on the flashin 36 at the bottom of the opening 23, with the handle 21 in. contact with the upper edge of the vertical gutter edge 37.

The middle sash is seated between the upper section 17a of guide channel 17 and rests on the ledge 18. The lower edge of the middle sash 15 is overlapped by the top edge of the lower sash 14. The pressure buttons 19 in the front face of the channel 17 press against the lower sash to press it in turn against the middle sash to form a weather tight seat at that point. By referring to Figure 2, it will be seen that sash 15 is in a plane outward of that of sash 14 so that rain water running down the outside of sash 15 will run down the outside face of sash 14 and not enter the joint between the middle and lower sashes.

The upper edge of sash 15 overlaps the lower edge of magazine sash 16 and is pressed firmly thereagainst in a weather-tight seal by the lower cam ends 35 of the latches 33. Again the sash 16 lies in a plane outward of the middle sash 15 and therefore rain water will continue over the joint between the two sashes and down the outside face of the middle sash 15. Thus a weather-tight glazed closure is secured when the Several sashes are in their closed position in the frame opening 13.

To open the closure for the passage of air therethrough, it is only necessary to lift upwardly on the handle 21 of the lower sash 14 and slide the sash upward vertically of the channel 17 in front of the middle sash 15. The outwardly extending flange at the lower edge of the sash 14 extends into the vertical plane of the middle sash 15 and as the lower sash is moved into register with the middle sash, the flange 2t engages and supports the lower edge of the middle sash, lifting it off the ledge 13. At the same time, the upper edge of the sash 14 enters between the latch cam surface and the sash 15, springing it inward so that the end of the shelf 34 rides on the inner face of the sash 14. The continued upward movement of the lower sash .14 carries the middle sash 15 with it out of the upper end of the channel 17a and into the magazine until the middle and

lower sashes

15 and 14 are in register with the upper or magazine sash 16. At this point, the lower edge of the sash 14 will pass above the upper edge of the latch shelf 34. The flexibility of the latch 33 causes the shelf 34 to be snapped outward toward the sash 15 and under the lower edge of the sash 14. Release of upward pressure on the handle 21 of sash 14 will cause the lower edge of the sash to fall slightly and come to rest upon the horizontal shelves 34 of the two latches 33, as shown in Figures 3, 4 and 5. The sash 15 is supported on g the flange 20 of the sash 14.

As seen in Figure 3, the opening 13 is now twothirds clear of all obstruction to the passage of air. To fully clear the opening 13, the magazine containing the three

sashes

14, 15 and 16 may be tilted inward on its pins 27, as seen in Figures 4 and 5. The tilted magazine 49 is supported by hinged brackets which fold up when the magazine is in its vertical position.

The cradle elements 32 support the upper portions of the nested sashes and prevent their falling out of the magazine 40 when it is tilted as seen in Figures 4 and 5. The

sashes

14 and 15 may be easily lifted out of the tilted magazine for cleaning both sides thereof. The outside of the sash 16 may also be easily cleaned when the magazine is in its tilted position. Thus both sides of the sashes may be easily cleaned from the inside of the closure, Without disturbing the screen 30.

To close the opening 13, it is only necessary to return the magazine to its vertical position, wherein the spring lock 38 engages the upper edge of the magazine frame 23. The two latch finger grips are grasped by the operator and pulled inward until the horizontal shelves 34 of the latches 33 are clear of the bottom edge of the sash 14. The sash 14 then instantly falls vertically of the channel 17, carrying the supported sash 15 with it. The sash 15 is deposited on the ledge 18 and the sash 14 continues downward until it rests on the lower edge of the opening 13 to again take the position illustrated in the Figures 1 and 2, wherein the closure opening 13 is entirely sealed against the passage of air or water.

It will be noted that with the magazine in its vertical position, the

sashes

14 and 15 need not be touched at all to close same. Again in opening the window, the middle sash 15 is not touched but is automatically picked up by the flange 20 of the lower sash 14 as the sash 14 is moved into the magazine 40. The three sashes remain in the same relative vertical planes at all times. There is no necessity to rearrange or otherwise disturb the relative positions of the several sashes.

Since all of the elements remain mounted upon the frame 10, even when the opening is entirely clear for ventilation of the enclosed area, there is no need to provide storage space for any of the elements during certain seasons of the year. Furthermore, the amount of ventilation can be regulated by the proper manipulation of the three movable elements, in contrast to prior art devices which require their openings to be entirely closed or entirely open.

In the foregoing specification the invention is described as having two vertically movable sashes, but a single movable sash could also be used if only a small window opening is needed.

It will now be clear that there is provided a device which accomplishes the objectives heretofore set forth. While the invention has been disclosed in its preferred form, it is to be understood that the specific embodiment thereof as described and illustrated herein is not to be considered in a limited sense as there may be other forms or modifications of the invention which should also be construed to come within the scope of the appended claim.
