. A'I'I'DRN EYE Patented Aug. 7, 1945 UNITED STATES PATENT OFFICE- 2,381,158 VENETIAN BLIND Oscar Green, Detroit, Mich.

Application June 29, 1944, Serial No. 542,677 4 Claims. 01. 16il-l66) My present invention, in its broad aspect, has

each slat so that the'slats are held in position to the end that by reversing the sides of the blind toward the source of light .two difierent light exposures are provided, one by reversing the bottom and top of the blind two additional exposures are provided. In looping the supporting cords provision is made for not only securely supporting the slats but fixing their relative positions, and the entire structure is simplified, rendered more practical and efflcient, and improved over devices in the same general category now in use.

Among the many objects and advantages of my invention are (1) to provide a Venetian blind which has no fragile or complicated parts likely to get out of order; (2) to provide a Venetian blind which may be used with ordinary window shades and decorations such as drapes or the like, or curtains, and which is easily removable when not in use and may be kept clean; (3) to provide a Venetian blind whose cords may be readily replaced when worn or frayed by the owner without outside help, and which will fold up for storage, shipment, or to be taken on trips; (4) to provide a device which may be manufactured of metal, paper board, wood or the like by an ordinary stamping process and may be suitably reinforced; and (5) to provide a blind which maybe used with any conventionalwindow construction.

Other and equally important objects and advantages of my invention will be apparent from the following detailed description and drawing,

' but it is" to be understood-that changes in form,

size, shape, construction and arrangement of parts may be made without departing from the spirit of my invention or the, scope of the appended claims.

In the drawing wherein I have preferred form of my invention a v Figure 1 is a front elevation showing my invention applied to a window construction and frame;

Figure '8 is a plan view of a slat showing the cord openings therein;

Figure 9 is a perspective view showing the use of a reinforcing strip or bar, and

Figure 10 is a detailed section showing the use In the drawing wherein like characters of reference are used to designate like or similar parts:

The numeral l as used in Figures 2-3-4-5 designates the normal top of my Venetian blind structure 2. My Venetian blind is formed with slats 3 which may be of metal, paperboard or the like, and may be fabricated bya stamping operation. Each slat 3 has three pairs of spaced apart o ings 4 along one edge. These openings are divided by a web part 5.

The supporting cords 6 of my blinds may be of any suitable type, and the outside cords I are provided with looped eyes 8 at the top and bottom ends. In hanging the blind the looped eyes 8 are simply engaged over the heads of tacks 9 or the like, so that the blinds may be quickly and easily mounted or taken down.

In attaching the slats 3 to the cords 6, the cord is looped as at l0 about the web 5. That is, a

length of cord is run through the outer opening as at a then across the under p rt of the web as at b, then up through the inner opening as at c and across the top of the web as at d and then down through the outer opening as at e as shown in Figure 6, whereupon the loop is drawn'tight as in Figure '7 to support theslat in position on the cord. Worn or frayed cords may be easily replaced by the owner;

A reinforcing strip ll may be mounted on a slat across the web portions. 5, or metallic or plastic eyelets I2'-see Figure ill-may be used about the openings 4 to reinforce the same.

From the foregoing it is believed that the operation and advantages of my invention will be apparent, but it is again emphasized that interpretation of the scope of my invention should only be conclusive when made in th light of the subjoined claims. a

I claim:

1. A Venetian blind comprising slats, cords supporting the slats, said slats having pairs of openings, the cords being looped through the openings to support the slats.

2. A Venetian blind comprising slats, and said slats being reversible in operation, pairs 01' openings in each slat, cords supporting the slats and looped through the openings, and said blinds being reversible as to the side presented to the light and as to the top and bottom edges.

3. A Venetian blind comprisin spaced slats, each slat having pairs of transversely spaced openings adjacent one edge, a cord passi through vertically aligned pairs of openings, said cord being looped through th openings.

4. The invention as described in claim 3 wherein the loops are formed by training the cord through the outside opening, then passing the same across the web, and through the inside opening and then across the web and through the outside opening.

OSCAR GREEN.
