3 Claims.

This invention relates to a combination allpurpose door adapted for use generally in buildings for outside doors and especially intended and adapted for use with doors of homes which open to the outside or exteriorly of the enclosure.

More particularly, the primary object of the present invention is to provide a combination door which will eliminate the need for a separate screen door and storm door and in which will be incorporated the advantages of both types of doors in addition to a conventional door.

Another object of the invention is to provide an improved construction of door capable of being quickly and easily converted from a combination door and storm door to a combination door and screen door and which will eliminate the need for separate screen and storm doors.

Still a further object of the invention is to provide a combination door which will be more durable than conventional screen doors, the screen of which will not be damaged by young children pushing thereagainst, and which will prevent dust and dirt from being blown through the door, through the lower part thereof.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating the preferred embodiment thereof, and wherein:

Figure 1 is a side elevational View on a rela tively reduced scale of a preferred embodiment of the invention looking toward the outer side thereof and showing the screen incorporated with the door;

Figure 2 is an enlarged longitudinal sectional view taken substantially along a plane as indicated by the line 2-2 of Figure 1 and showing the transparent pane of the door in a retracted, open position;

Figure 3 is an enlarged horizontal sectional View taken substantially along a plane as indicated by the line 3 3 of Figure 1;

Figure 4 is a vertical sectional View taken substantially along a plane as indicated by the line 4-4 of Figure 2 and showing the transparent pane in a partially raised position; and

Figure 5 is a fragmentary vertical sectional View taken substantially on the same plane as Figure 2 and showing the door with a storm window substituted for the screen window thereof.

Referring more specifically to the drawing, S designates generally the improved door in its entirety and which comprises the invention. rlhe door in Figures 1, 2, and 3 is illustrated disposed in a frame I defining a door opening and swingably supported along one edge thereof to a stile of the frame 1 by means of conventional leaf hinges 8. The door 6 is provided adjacent its opposite longitudinal edge and preferably slightly below the mid-point of the top and bottom thereof with a conventional door knob 9. It will be understood that the door 6 is provided with a knob 9 on each side thereof and that said knobs are connected to and operate a latch means, not shown, for engaging a keeper in the other stile of the door frame 'I and that a suitable lock, not shown, may also be provided for locking the latch means.

The door 6 comprises an inner, relatively thick panel I I) and an outer, thinner panel II which is preferably secured to the outer side of the inner panel I0 by countersunk screw fastenings I2. The upper portion of the door E5 is provided with a relatively large opening I3, formed in the panels I0 and II and the outer side of the panel I0, around the top and sides of said opening I3 is reduced in thickness and the space, thereby afforded, is filled by a removable filling strip I4 which is detachably secured between the recessed part of the outer side o-f the panel I0 and the panel II by certain of the fastenings I2.

The panel IIJ is provided with a relatively deep well I5 which opens at its upper end into the bottom of the opening I3. The portion of the panel I 0, defining the opening I3 is also provided with downwardly and inwardly opening channels IB, the outer sides of which are defined bythe lling strip I4. The vertically extending inwardly opening channels I 6 also form continuations of the 4edge portions of the well I5. The channels I6, and the edge portions and bottom of the well I5 are lined with felt or similar material Il.

As best seen in Figure 4, the top rail portion of the inner door panel I 0, adjacent the upper corners thereof, is provided with corresponding outwardly opening recessed portions l having restricted passages I9 communicating with the ends of the upper, downwardly opening horizontal channel I 6. A roller 20 is journaled in each of the recesses IB on a pin 2l and a tape 22 is wound on each roller 20 and extends downwardly therefrom through the associated opening or passage I9 and into the vertical groove or channel IB which is located directly beneath.

A pane of glass or other transparent material 23 is sized to t, when in a retracted position, substantially within the well I5 and with the upper edge portion thereof protruding slightly into the lower part of the opening I3 and with the side edges of said portion disposed in the inwardly opening side channels I 6. The lower, free ends of the tapes 22 are secured to the side edges oi the pane 23 by pins or other suitable anchoring means 24. A spring 25 is interposed between each roller 20 and its pin 2|; said springs being anchored at one end to the pins and at the opposite ends thereof to the rollers causing said rollers to be revolved in a direction for urging free ends of the tapes 22 upwardly toward the recesses I8. It will be readily apparent that the i outwardly opening recesses I8 will be exposed by removal of the panel II and the filling strip I4 to afford access to the rollers 23.`

An open frame 26 is detachably mounted in the portion of the opening I 3 formed by the-panel I I; said frame 26 being sized to t relatively tight in said opening and being swingably supported therein by means of leaf hinges 2'I at the top of the frame 26 and in the upper part of the opening- I3. The frame 26 is provided with an opening 28 across which a strip of mesh wire fabric 29 is stretched. The frame 26'is provided with. a removable outer section 30 surrounding the opening 23 thereof and between which and the remainder of the frame 2B, the edge portion of the wire fabric is clamped. The removable frame portion 30 may be secured in position in any suitable manner and is intended to be removed only for replacement of the screen 29, ifisuchv should be required. A spring, latch member'- 31 is suitably anchored at one end thereof between the panels I and I I and projects therefrom into the lower part of the opening I3 and is adapted to engage over the bottom rail of the frame 26, inwardly of the wire fabric 29, for detachably retaining said frame in its normal, closed position of Figure 2.

As illustrated in dotted; lines in Figure 4, the inner side of the pane23 is provided-with recessed portions adjacent the upper edge thereof forming nger holds 32 which are disposed slightly above the bottom oi the opening I3 when the pane 23 is in a retracted position in the Well I5, as illustrated in Figure 2. A grip may be obtained on the pane 23 by mea-ns of the nger hold 32 for raising the pane 23 from its-fully-retracted position, of Figure 2 to a partially raised and closed position, as seen in Figure 4*. ori to a fully raised and closed position, as seen in Figure 5. The spring actuated rollers inurging'the tapes 22 toward a wound positionV thereon will assist in raising the pane 23 by substantially counterbalancing the weight thereofand areof sufficient strength to retain the pane 23` in either a partially or fully raised, and closed position. The felt linings of the channels I and the well I5 will also function tofrictionally retain the pane 23 in any position to whichv it is manually moved and will cushion said pane to preventl damage thereto resulting from slamming of the door 6 and also function as weather stripping to prevent the passage of air between the pane 23 and opening I3when the formerfis ina fully raised and closed position, as seen in Figure 5.

Figure 5 is a fragmentarysectional view illus- 6 trating the door 6' employed as a storm door and for use during cold weather. A storm window, designated generally 33 and comprising a frame 4 34 having an opening 35 and an inwardly opening channel 36, which opens into the opening 35 is shown mounted in the opening I3 and in place of the

screen

26, 29. A glass pane 31 or a pane of other transparent material has its marginal edge portions seated in the channel 36 and closes the opening 350i said frame 34. The upper rail of the frame 34 is swingably secured in the upper part of the opening I3 by hinges 38 in the same 2 manner and for the same purpose as the hinges 2'I, and it will be readily obvious that the same hinge leaves which are secured to the panel II may be utilized for mounting either the window screen or storm window by merely removing the hinge pins and interchanging the screen or storm window. It will be readily seen that either of said closures may be selectively mounted in the opening I3 for providing either a storm door with the pane 23 raised and the window 33 utilized or a screen door with the pane 23 retracted and the

screen closurel

26, 29 employed. The panes 23 andV 3l' of the storm door will provide an air chamber therebetween which will effectively function to reduce the amount of heat or cold which would otherwise be conducted through the pane 23. The storm frame 35 may be lined with felt or other weatherstripping 39 to prevent passage of air between the frame and opening I3.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit and scope of the invention as hereinafter dened by the appended claims.

I claim:

1. A combination door comprising an inner panel and an outer panel, means for detachably connecting said panels together, said door being provided with an opening inthe upper part thereof, said inner panel being provided with a well in the lower portion thereof and opening upwardly into said opening, a transparent pane for normally closing said opening, said pane being retractable into said well, and a window frame swingably and detachably mounted in said outer panel and closing the opening thereof.

2. A door as in claim l, and a sheet of mesh wire fabric engaged in said frame and combining therewith to form a screen window.

3. A door as in claim l, and a pane of transparent material closing the opening of said window frame and combining therewith to form a storm window and combining with the pane of said door, when in a raised and closed position, to form an air chamber within the door opening.
