WINDOW BLIND MADE OF WOVEN FABRIC Filed July 6, 1929 2 Sheets-Sheet 2 2 05725 50 fzmia Patented-Ian. '20, 1931 IDSHI-KO IWATA, OF KITATOSHIHA-GUN, TOKYO, JAE AN wmnow nnmn MADE or wovnn manic Application filed July 6, 1929. Serial a... 876,428.

My invention relates to a windowblind,

and particularly to that made of strlps of woven fabric. The object of my invention is to provide a window-blindmade of woven fabric,in which vanes are adapted to be effectively main-, tained in a stretched position being not. crumpled, and yet it may be readil washed.

1n the accompanging drawings orming a part of this s eci cation, Figure 1 is one form of embo ment of my invention as applied to a rolling blindf Figure 2 is a vertical thereof. 7 Figure 3 is a perspective view of one of the vanes.

Figure 4 is a part of the sectional elevation of the collapsible blind made according to my invention. Figure 5 is a erspective view of one of the stretching mem rs fixed to the vanes.

Figure 6 is a plan view of the vane with said stretching members.

According to my invention, the laths or vanes 1 of the blind are made of strips of stifi woven fabric of desired width and length. On both selvedges of the. fabric sectional elevation forming thevane are formed tubular edges 2 I by sewing together the turned selvedges with the vane proper. through each of the tubular edges 2 is detach- .ably inserted a stretching frame or rod .3 4

made'of steel, bambo, celluloid, or any other resilient material. At the points where the vanel is connected to the vertical connecting strips 4, fla s 5 are cut from the selvedges instead of orming the tubular edges, and

the said flaps .5 are united to the vertical.

connecting strips 4. In the above-mentioned manner, a plurality of fabric vanes 1 are united to the vertical strips 4 so as to form a so-called Venetian blind.

Imthe embodiment shown in Figures 1, 2 and 3, where the-invention is applied to a F 5 and6, ,wh'erethe invention is applied to a As shown in Flgure 3,

rolling blind, the uppei end of the blind made.

collapsible blind, the upper end of the connecting' strips 4. are umted to a fixed bar 8. On this bar is provided a guide ulley'9 about which is passed" a cord or cab e 10 for rais- 7 ing or dropping the ment, at the points where the vertical strips 4 are connected, there are provided the reinforcing and stretching members 11 fixed to the vanes. The member 11 is made of a sheet of metal, such as aluminium, and has a length 00 equal to the width of the vane 1' i. e. distance between "the rods 3 on both edges. In the member 11 a pluralit of claws 12- are stamped out, whereby t e member ll-is securely fixed to the vane 1 by bending the penetrated point of the claws 12 on the reverse side of,the vane. On the 'mdmber 11 there is also formed an eyelet having a flange 13 which is passed through an opening formed in the vane 1 and is turned outwardly on the reverse side. of the vane. The cord 10 is passed through the eyelets 13. I

From theforegoingit will be seen that in the window-blind made according to my invention, the strips of fabric forming 7 the vanes are efiectively maintained in a stretched position being not crumpled, so that it will be prevented from deformation, and yet when desired it may be, 'subjectedto 'a washing operation by readily removing the $0 7 stretching rods 3. h t The connection of the vanes l'by means of flaps 5 to the vertical strips 1 renders it possible that the vane'l may be united to the vertical strips 4 at a; desired angle and with a de- 86, sired interval of distance.

While I have shown two forms of embodiments of my invention, it will be understood 7 .that various changes maybe made within the scope of the appendedclaims. p 90, WhatIclaimis:='

1. A window-blind comprising a plurality of vanes each consisting of-a strip of woven K fabric" having tubular edges and flaps on both selvedges, stretching rods -;ii\$lted as: through said tubular on the vane, vertical connecting strips made of flexible? n a- .terial to which said vanes are united b c (if said flapsformed on the edges of v and reinforcing and stretching membere fi i 13;;

evane i blind". (In this embodi-- 55 t to the vanes, which members each consist of a metal sheethaving stamped out claws and a flanged eyelet b means of which the member is securely fixe to the vane.

2. A window-blind comprising a plurality of vanes each consistin' of a strip of woven fabric having tubular e ges and flaps on both selvedges, stretching rods inserted through said tubular edges on the vane, vertical cnnecting strips made of flexible material to which said vanes are united by means of said flaps formed on the edges of the vane; rein orcin and stretching members fixed to the vanes, w ich members each consist of a metal sheet having stamped out claws and a flanged eyelet'by means of which the said member is securely fixed to the vane, a fixed bar connected to the upper ends of the vertical connecting strips, a guide pulley providedon said fixed bar, and a cord for manipulating the blind, said cord being passed around the said guide pulleyand through said eyelets in the stretching members fixed on the vanes.

In testimony whereof I aifix my signature.
