4 Claims.
This invention relates towindow screens, the object being to provide a new and improved screenstructure for usein screening window openings in buildings. The screen is particularly adapted for use in psychiatric hospitals and asylums and is of sufficient strength of fabric and .of a form to provide a screenfabric yieldable under pressure applied thereto and in which the edges of the screen are housed within a recess provided in the framemember therefor. The arrangement further provides a structure in which there are no portions thereof permitting the inmates to tamper therewith and avoids use of the usual bars across the window openings heretofore commonly used to prevent the inmates effecting an exit. By use of our improved screen all indication of barred window openings is avoided and thusthe inmates are notdisturbed by the thought of confinement induced by use of bars.
A further feature and object of the invention is .toprovide a. screen structure in which the fabric is maintained under tension, the arrangement being such that tension is applied at several opposed points on opposite sides-of the frame whether the frame be of rectangular form with straightsides or frames of other peripheral shape.
It. is also anobjectof the invention to provide a screen .structure comprising spaced binding strips and internal bracing lugs located therebetween.
These and other objects and features of the invention are hereinafter morefully described and claimed and the preferred character ofconstruction of a screen embodying our invention is shown in the accompanyingdrawing in which- Fig. 1 is a cross section of a side rail and portion of screen showing our improved construction.
Fig. 2 is a vertical section taken on line 2-2 of Fig. 1 showing the arrangement of the parts as used in a rectangular frame work.
Fig. 3- is a section similar to that shown in Fig. 1 showing. an alternative arrangement-of parts.
It is to be understood that the screen may be other than of rectangular form of frame and screen fabric as theinvention is utilizable in hexagonal, circular in form, or when one or more sides of the frame have-a form on a radius as maybe required to fit various shapes of openings. In either case,-however, the, frame and the. fabric tensioning .means:.are .allof the same character.
In the rectangular form of screen shown-in Fig. 2 the side rail l is joined to the top cross rail 2 by welded joints 3 and a strengthening bar 4 maybe secured to the two parts I and 2 at the :corner and a further strengtheningplate 5 may also extend across the corner within the frame as indicated in Fig. 2 securing the, flange 6 of the rail 1 .to the similar flange I of the cross rail 2.
In the preferred construction the rails are substantially rectangular .in cross section and formed of two separable sheet metal parts I: and 8. Strengthening 'lugsil are providedtherebetween and preferably welded to the portion I while the part 8 is secured to the strengthening lug-9 by means of screws 10.
The part I provides a smooth and unobstructed surface which serves as the interior face of the frame and-the opposite side wall of the part I is. return bentas indicated at ll,1to form a recess to receive-an inturned end [2. of the member 8 and, after assembly of these return bent: portions, the screw I0 is introduced to hold the part8 inassembled relation with the part I. The part 8 on the side rails are notsecuredto the similar removable part on the cross rails. By removal of the part 8 of the several rails,: the screen fabric is readily introduced with its peripheral edge in the recess of. the frame. member l.
The twoside wallsl and .8 are inturned .at their inner edge as indicated at l3 and. I4 and are spaced at their inner edges .to provide an opening to the recess [5 into'which the'edge of the screen fabric is introduced. Theedge of the screen within the recess has secured thereto, on the respective opposite sides, strips l1 and 18 which are secured together by means of screws I9. Thesestrips I! and 18 at their outer edges are outbent and then inbent to form channels 20 in each case, which are. opposed to the channels formed by .theinbent. portions l3 and [4 of the. frame. The strips ll and I8 are of comparative short lengthsso that there are several such strips in both the 'side and end rails. A greater or less .length of stripnmay be utilized as maybe desired and are spaced .well .apart at the meeting point of the side andend. rails.
Each of the strips I! and 18 has a lug-2l inbent about the central portion of a bow spring 22. as will be clearly understood from Figs. 1 and 2, and the free ends 23 and 24 of each spring seat in the channel, 13 or I4 for the springs on opposite sides of the .fabric and are slidable "therein. In: assembling the-parts hand e oft-he sion to thereby place the fabric l6 under tension. By the arrangement of the strips I! and I8 in short lengths the fabric is more uniformly tensioned than if they were of the full length of the fabric as shown in our U. S. Letters Patent No. 2,173,334, Sept. 19, 1939. Greater uniformity in tension is therefore secured in the structure as herein shown as separate portions of the fabric are independently tensioned while, with the strips running the full length of the edge of the fabric, portions thereof which may have a little greater fullness in the weaving of the fabric, will not be under the same tension as other por- -:tions of less fullness. Thereby by use of the short strip we are able to secure a more uniform tension throughout the fabric than with the full length strip,
It is further to be noted that by use of a b spring slidable in the portions l3 and M of the frame and fixed to the strip l1 and 18 the fabric may shift as a whole'relative to the frame and thus although the springs may not all be exactly alike in deflection under tension the fabric may be centered in the frame under equal tension from all sides.
An alternative form and arrangement of parts is shown in Fig. 3 in which a flat bow spring is used rather than the round wire spring 22 previously described. For use with the flat spring as shown in Fig. 3 the end portions I3 and I 4', corresponding to the portions l3 and [4 shown in Fig. 1, are provided with flat surfaces 26 in each instance, and the strips l7 and I8"l1kewise having fiat surfaces are engaged by the ends and central bowed portion of the respective springs.
The portions H and I8 each have an 1nturned portion 21 for fastening the spring to the strip. These springs 25 function and are similar to the springs 22 previously described.
It is believed evident from the foregoing description that the various features and objects of the invention are attained by the structure described and. by which an efficient screen is provided which not only prevent ingress of insects and the like but will provide an effective barrier preventing destruction by inmates of an asylum seeking an egress therefrom.
Having thus fully described our invention, its utility and mode of operation, what we claim and desire to secure by' Letters Patent of the United'States is:
