Sept..28, w D|EHL SCREEN AND DOOR STRUCTURE Filed June 2, 1952 FIG. 5

Patented Sept. 28, 1954 UNITED STATES PATENT OFFICE SCREEN enonooe s r-Recruits William Louis Diehl,-l lanville,v Calif; Application June 2; 1952; Serialhlo'. mass The present invention relates to the screening of a two-part swinging door c'o'mmonlyknown-asa; Dutch door inwhich the top part or half of the door can be swung to open position independently of the bottom half.

It is a general object of the invention to provide an improved method of screening such doors which eliminates the undesirable factors" pres ent methods and to provide a full screen for the upper portion of the door which requires no' hardware or precise fitting and which does not have to be handled in any way to facilitate ingress or egress through the doorway. v

Another general object is to provide a new screen construction for doors. Y

Another object of the invention is to provide a screen for a Dutch door which allows the door to function in its normal and intended method whetherthe door is hung to swing inwardly or outwardly.

Another object of the invention isto'provide a; screen fora Dutch door which is securely held in placesothat nowarping due to weather'- changes is likely. I g Another object of the invention is to providea Dutch docr' screen construction which adds" to" the attractiveness of the door installation and which will not interfere with the operation of the door, particularly in inclement weather.

Another object of the invention is to provide a Dutchdoor screen construction which can be easily and quickly installed and which is economiii s The above among other objects of the invention are attained as described in connection with a preferred embodiment of the invention, as illustrated in the accompanying drawings, in which:

Figure l is a front elevational view of a Dutch door construction embodying my invention.

Figure 2 is a fragmentary vertical sectional view with the door shown in elevation.

Figure 3 is a fragmentary detail horizontal section of the screen construction taken at an intermediate point along the left side of Figure 1.

Figure 4 is a section similar torFigure 3 and showing a modified form of the invention.

Figure 5 is a horizontal sectional view showing the upper door half in partially open position.

The present methods of screening Dutch doors are to provide a full independently hung screen which requires a construction in which the screen must be hung to swing one way and the door is hung to swing the other way, or to provide a type of roll screen which is awkward and interferes somewhat with the normal use of the door and with ingress the egress through the door epen-' The present inventiofr dbviates the undesirable features of theknowfi methods of screening Dutch doors and basically comprises mount-ii'ig a screenedframe over the upper half ofthe door and attaching said frame 13d the bottom half of the door which screened frame'isoffset with ref spect to the top half so that both tl-iet'o'p and the bottom half of the door can close normally: The screen incorporates, a" fin or; seer construction around its edge whichengages the door stop and is engaged by the uppe "ali of the door when it closed. This scr pg of the upper ha'lfof the door can be effected-by construction of'the door with the sreee as integral part ofthe lower' half of the door or a separate attach ment" thereto can be readily installed on existing doors. As shown harem,- the particular embodiment is concerned with the-second typeof construction.

Referring to the drawings; the invention includes wDutchv door construction comprising a lower half I'll andupper' half" Ht hinged respectively at l2 to a: door frame l3 having a conventional form of door stopsorstrip; l4: therein. Both the upperhalf and the lower halfhave their closed position determinedbythis; door stop the usual fashion. A latch i5 is provided for connecting the two halves. Asshow'n, the' upper and lower half have an ofiset meeting point at IGto provide an overlapping conventional ship" lap seal, al u fii smar b el inat l di "tta'ched dt e-oute'r face of-the lbwerhalf I0 is a screen I! comprising a frame 58, a screen fabric 19 of the usual construction and mounted in the usual manner therein, and a metallic rib or fin 2| extending around the periphery of the screen at the two sides and at the top. As seen in the Figure 3, this fin is positioned substantially flush with the inner surface of the screen frame l8 and engages the stop I4 with the body of the screen disposed inside of the stop, so that the upper door half H can close against the stop and the fin 2| is caught between the stop and the upper half II. This fin may be of any suitable sheet metal, plastic or screen construction and is attached in a rabbeted portion 22 of the screen frame by suitable fastening means. The lower part of the screen frame [8 is provided with a bracket extension 23' having upper and lower sets of fastening screws 24 and 26 by means of which it is attached to the lower door half II]. If desired a suitable shelf 21 can be supplied in the frame construction of the screen for decorative purposes.

When the screen is in the form of an attachment to be applied after the swinging of the doors or to existing Dutch door installations, the installation may be effected in the following manner. With the lower door half l closed, the screen is placed manually in the position shown and the upper door half I I is then also closed so that it holds the metal fin 2| against the door stop M. Then centering and adjusting the screen to the proper position with respect to the door, the three installing screws as shown are set in place. If upon opening the top half of the door H, the metal fin 2 I does not securely engage the door stop at all places, suitable adjustments can be made to tilt the screen, by installing cardboard or other suitable shims beneath either the upper or the lower screws. A shim 28 is indicated in dotted lines in Figure 1. If by chance, the fin should not clear in a particular door installation in swinging in and out, a simple trimming operation with a pair of shears is all that is required.

Figure 4 shows a modified construction in which a rabbeted stop Ma is employed to be engaged by the peripheral edge of the screen frame l8.

While I have shown certain preferred forms of the invention, it will be apparent that it is capable of variation and modification therefrom so that its scope should be limited only by the scope of the claims appended hereto.

I claim:

1. In a Dutch door structure having upper and lower halves for installation in a door frame having a stop extending around the inner periphery thereof, a screen construction mounted on the lower door half and having a peripheral edge portion adapted to engage against the stop, said upper half of said door being engageable with said peripheral edge portion in closed position.

2. In a Dutch door structure having upper and lower halves for installation in a door frame having a stop extending around the inner periphery thereof, a screen construction mounted on one door half and having a peripheral edge portion adapted to engage against the stop, said other half of said door being engageable with said peripheral edge portion in closed position.

3. In a Dutch door structure, having upper and lower halves for installation in a door frame having a stop extending around the inner periphery thereof, a screen construction mounted on one door half and having a peripheral edge portion adapted to engage against the stop, said other half of said door being engageable with said peripheral edge portion in closed position, the mounting of said screen including means for effecting tilting adjustment thereof.
