Bath, Ohio Application June 14, 1950, Serial No. 167,996 3 Claims. (Cl. 160-90 This invention relates to an improvement in combination screen and storm doors, and more particularly to a self-storing door, having advantageous safety features for permanently hung combination storm and screen doors.

Heretofore, the most common combination storm and screen doors have been those in which removable screened and glazed sashes have been interchangeably mounted. While such combination doors are far more convenient to handle and permit a more simple conversion from a screened to storm closure than the prior practice of hanging a storm door on the hinges of a screen door, such removable sash doors still presented the inconvenience of having to store relatively heavy sash when such sash is not in use. The interchanging of stored sash at the change in seasons is often a nuisance and the problem of storing sash presents a real problem in smaller modern homes where storage space is at a premium.

To overcome the nuisance of interchangeable sash doors, recent efforts have been made to market so-called self-storing doors which'follow the construction of the so-called self-storing storm windows by providing three sashes slidable vertically in the door, one sash being screened and the other two being glazed. In such prior art doors, the two glazed sashes are manipulated as double hung glazed window sash so that, with one glazed sash in the upper half of the sash opening and the other in the lower half, the door will provide glazed storm protection; with both glazed sashes positioned in onehalf of the sash opening, the screened sash may he slid into the other half to provide a screened opening. Such self-storing combination doors have not been widely accepted. With the lightness of construction required in a door, the sashes tendto cock and jam, the users frequent reaction being that it would be easier to revert to the interchangeable sash employed in the earlier combination doors. Further, the vertically slidable sashes, if hung securely enough to be relatively free of rattles, are often relatively difficult to remove for cleaning. A serious objection, also, is thatwith only an upper or lower half of the sash opening being available for the screened sash, poor ventilation is obtained in the summer time. Still another objection to the above described prior art self-storing doors is that a horizontal lintel or sill of a sash at the mid-point of the sash opening falls at the eye-level of many users and is unattractive to nearly all users. And finally, the latches secure enough to hold a raised sash against slamming are nearly always too secure for convenient operation of the sashes. Some efforts have been made to increase the area of the sash opening available for screening by having all or a part of the glazed sashes disappear into a panel below the sash opening, but this remedy raises a further objection: it eliminates the area available for a mail slot and such a panel well traps rain and dirt which soil the glazed sash and promote rusting or rotting of the door and sash frames.

It is an object of this invention to provide a self-storing combination storm and screen door which overcomes the several disadvantages o f prior art doors, as discussed above, and, in addition, provides a safety feature which has proved very desirable to users, particularly housewives, which has not been available in combination doors heretofore available. A door made according to our invention is provided with a sash opening which is divided vertically. On one side of the opening is a relatively fixed but removable glazed sash and on the other side the inside of the doors.

line 4 -4 of r 2,702,595 l ate ed r b zz, 1955 is a relatively fixed but removable screened sash Behind these two sashes is a third glazed sash whichhas a width equal to approximately one-half the horizontal width of the sash opening andis freely slidable across theent'ire width of the sash opening in the door. In either winter'or summer, the housewife is able to stand out of the draft hehindthe g'l'a ze'd sash to talk to persons through the screened opening; such persons maybe strangers to whom the housewife would hesitate to speak in the winter hecause'ofthe necessity of opening a storm door and inthe summer because ofthe fear that the screening could be easily cut. Even the n'iost titnid housewife 'feels that she could slam the horizontally sliding glazed sash across the screened opening before a substantial cut could be made in the sc eened opening. Many housewives appreciate the sliding glazed sash because it can be quiekty closed and, thereby, provides a means for quicklyjc'ut'tirig off an undesired conversation through the screened opening.

Another advantage of our door is that the several sashes are readily removable 'forclea'ning, but onlyf'rom A Other and further objects and advantages of our invention are disclosed in the following specification, elaims, and dra'wings, in which: s

s Fig. 9 is a 'hiirizontal section taken along the line 9-9 of F Forstrength and rigidity, doors made according to this invention are preferablyrna'de' of sheet metal rolled or otherwise formed into hollow box sections. As shown in the drawings, such adoor is comprised of ajframe 10 .having'sill, jamb, and lintel elements 11, 12, and 13 defining the sash opening in which the sashes are mounted. Between the sill elementll and the sill 'of the'frame10 is a fixed panel 14. proyided with a suitable ma'ilor parcelslot 15, which latter may be of any conventional or convenient construction. I n

Three sashes are mounted in the sash opening of the d'oor a'n outer glazed sash 30, an outer screened. sash 40, and an inner sliding sash 50. The frames of the several sashes are of overall box channel construction provided with suitable grooves 'tofreceive the glass panes or screening fand the suitable lockingficlips therefor; 'additional channels are provided to receive felt rattle strips located to prevent the sashes from rattling against each other. One of the .jambs of the sash 50 is provided with a suitable handle 51. For purposes of the following description, adjacentja'rnbs of the outer sashes 30 and 40 are designated as 31 and 41 and the remote jambs are designated as 32 and 42', respectively (see Figs. 6 and 7).

As best shown i'nsection in Figs. 3 and 4, the sill element 11 is 'of an overall bo'x section, the upper side of which is configured to provide an inner sliding sash flange 16, and, falling outwardly to the weather side of thedoor, a sliding sash track 17 and a drain eave 18. Extending horizontally betweenthe jambs of the frame 10 is an angle member constituting a. I( l.ll1'1 teI:-Sill 1'9 pace ab g h d a ne v .8. h i d i qnt le m of the counter-sill 19 being spaced below the track 17 and vertical element extending upwardly to provide, in cooperation with the shoulder of the track 17, a channel for receiving the outer glazed sash 30 and the screened sash 40. As is evident from Figs. 3 and 4, any rain which might splash through the screened sash 40 or drain onto the counter-sill 19 from the weather side of the glazed sash 30 may drain out to the weather side of the door over the drain eave 18.

As also shown in Figs. 3 and 4, the lintel element 13 is provided with an outer depending flange 21 and an inner depending flange 22 to define an upper channel into which the lintels of all the sashes are received. As shown in the drawings, sufiicient clear space is provided above the sashes so that, when any one sash is resting on the track 17, it may be lifted into the channel 20 a suflicient distance to permit the sill of the sash to be swung inwardly over the flange 16. When clear of the flange 16, the sash, at a slight angle to the vertical, may then be dropped out of the channel 20 and, thereby, removed from the door. As shown, each of the channel flanges 21 and 22 are lined with felt pads to prevent the sashes from rattling in the channel.

To secure the outside jambs of the outer glazed sash 30 and the screened sash 40, the sash-opening jamb elements 12 (see Fig. 6) are provided with flanges 23 against which the remote sash jambs are engaged when the outer sashes are dropped to their mounted position in the sill channel provided by the counter-sill 19. When mounted, the remote jambs of the outer sashes fit tightly against the jamb elements 12 and their flanges 23, the adjacent jambs 31 and 41 of these sashes abutting. It is to be noted that the adjacent jamb 31 of the glazed sash 30 is provided with a battan flange 33, which seals the vertical central joint between the adjacent jambs 31 and 41.

As also shown in Fig. 6, the inner sliding sash 50 is slightly wider than either of the outer sashes. Thus, outward movement of the outer sashes 30 and 40 being prevented by the flanges 21, 23, and counter-sill 19, inward movement of the adjacent jamb of the sashes will be prevented by the inner sliding sash 50, which is restrained by the track flange 16 and lintel flange 22. This means, however, that with the inner sash slid to one side, behind one of the sashes 30 or 40, the other sash (glazed sash 30 in Fig. 6) could be raised from the outside, and, when raised above the flange 16, its outer jamb 32 could be pushed inwardly, the sash 30 pivoting about its adjacent jamb 31. To prevent such inward movement of the remote jambs, the remote jambs carry pins 25, preferably equally spaced from the tops and bottoms of the jambs (to permit glazed and screened sashes to be mounted in either side of the sash opening by turning the sashes end for end). The pins are received in vertical slots 26 permitting the sashes to be raised up to the level of the track 17 but preventing the remote jambs 31 and 41 from being pushed inwardly.

Although the sashes may not be removed from the outside, they are readily removed from the inside, the inner sliding sash 50 being the key to the locking of the sashes and 40. To remove the sash 50, it is simply lifted into the channel 20 and over the flange 16, as described above. With the sash 50 removed, the screened sash 40 is then lifted above the level of the track 17 and pivoted about its remote jamb 42 until its inner jamb 41 is on the track 17. The sash 40 is then slid on the track 17 until the pins 25 are clear of the slots 26. The sash 40 is then removed in the same manner as was the sash 50. With the sashes 5'0 and 40 removed, sash 30 may be removed in the same manner as was sash 40. After cleaning, or repairing, the sashes 30, 40, and 50 may be replaced in order.

A somewhat sturdier means of preventing inward and outward movement of the remote jambs of sashes 30 and 40 while sash 50 is in place is shown in Fig. 7. In this embodiment, no slots 26 or pins 25 are employed. Instead jamb elements 112 replace the jamb 12. The inner sides of the jamb elements 112 are stepped to provide vertical channels 126 which receive the remote jambs 32 and 42 when the sashes 30 and 40 are inserted and the adjacent jambs 31 and 41 are abutted. The sashes are removed and reinserted with the same movements and order as described in connection with the embodiment in Figs. 1 to 6.

A still simpler but less convenient means for securing the remote jambs of the sashes 30 and 40 are shown in Figs. 8 and 9. In this embodiment, the jamb elements 212 are similar in section to the elements 12, but the flanges 223 are drilled to receive self-tapping screws 225 which are threaded into the remote jambs 32 and 42. Aside from cheapness, the only advantage of the embodiment shown in Figs. 8 and 9, and it is a questionable advantage, is that all the sashes 30, 40 and 50 may be removed, the sash-opening then being closed by a single screened sash (not shown) to provide a full-screened sash opening or by a solid sheet of plywood (not shown) for boarding up the doors of temporary residences. Except where these last-mentioned features are insisted upon, the modification shown in Figs. 8 and 9 is not generally recommended.

From the foregoing, it is apparent that our invention is not limited to any one specific embodiment but may be modified by those skilled in the art without departing from the spirit and scope of the invention as defined in the following claims.

What is claimed is:

1. In a self-storing combination screen and storm door, lintel, jamb and sill elements defining a sash opening, said opening comprising a major portion of the vertical area of the door, said sill element comprising a track flange, a track below said track flange and a sill channel located below and outwardly of said track, said lintel element having an outer flange and an inner flange, respectively coplanar with the outer edge of said sill channel and said track flange, to define a lintel channel, an outer glazed sash resting in said sill channel and extending into said lintel channel, said outer glazed sash being comprised of upper and lower frame members and adjacent and remote jamb members, said outer glazed sash extending to a mid-point between said jamb elements when said remote jamb member is fitted against a jamb element, a screened sash comprised of an upper member and a lower member and remote and adjacent jamb members, said screened sash extending from said sill channel into said lintel channel, its remote jamb member fitting against a jamb element and its adjacent jamb element abutting the adjacent jamb element, whereby said screened sash closes the balance of the sash opening partly closed by said outer glazed sash, an inner glazed sash mounted on said track and extending vertically into said lintel channel, said inner glazed sash being slidable from a position behind said outer glazed sash to a position behind said screened sash, said inner glazed sash having a width suflicient to close the screened opening in said screened sash when slid therebehind, and, when slid behind said outer glazed sash, sufficient to extend over the joint between said adjacent jambs but insulficient to extend appreciably over said screened opening, and said lintel channel being deep enough to permit any of said sashes to be lifted over said track flange while the upper portion thereof is in said lintel channel.

2. A door as defined in claim 1 in which said sill channel is comprised of a counter sill raised above said sill element to provide a drain passage toward the outside of said door.

3. In a door as defined in claim 1, flanges on said jamb elements to engage and prevent outward movement of the remote jambs of said outer glazed sash and said screened sash and means to lock said remote jambs against inward movement when in engagement with said flanges on said jamb elements.
