VNETIAN BLIND l Julius Reinike, Brooklyn, N. Y.

Application April 24, 1939, Serial No. 269,722

1 Claim..

This invention relates to window blinds and more especially to Venetian blinds.

The primary object of the invention is the provision of a blind of this character, vwherein the slats making up the same are arranged in a manner that a group thereof can be adjusted with relation to the remaining group so that the lower portion of the blind can be closed with the upper portion open or vice versa and additionally the '10 entire blind can be closed, that is to say, the slats thereof angle in a manner to exclude light through the blind.

Another object of the invention is the provision of a blind of this character, wherein the construction thereof is novel so that one portion of the same can be closed independently of the other portion or the entire blind closed in a single operation, the slats being adjustably suspended in a novel manner.

9@ A further object of the invention is the provisionof a blind of this character, which is simple in its construction, thoroughly reliable and emcient in operation, neat in appearance, readily and easily adjusted, durable, and inexpensive'to E@ manufacture andinstall.

With these and other objects in view, the invention consists in the features of construction, com bination and arrangement of parts as will be hereinafter more fully described in detail, illusa@ trated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto, appended.

In the accompanying drawing:

. Figure l is a Vertical longitudinal sectional view w through the blind constructed in accordance with the invention and the upper portion being open and the lower portion closed.

Figure 2 is a sectional view on the line 2-2 of Figure 5 looking in the direction of the ar- It rows.

Figure 3 is a View similar to Figure 2 showing the upper portion of the blind closed and the lower portion open.

Figure 4 is a view similar to Figure 3 showing 45 both the upper and lower portions of the blind closed.-

Figure 5 is a fragmentary elevation of the blind in the condition shown in Figure 2.

Similar reference characters indicate corre- 50 sponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the Venetian blind constituting the present invention comprises a header frame or bar Ill in which is swingable on l5 a horizontal axis the top turning rail II while supported by the header frame or bar are the raising and lowering cords or cables, one being denoted at I2, and by which the upper and lower series of louvers or slats I3 and I4, respectively, can be raised and Alowered for increasing or de- 5' creasing the longitudinal extent of the blind in the use thereof.

The louvers or slats I3 are suspended by inside and outside adjusting tapes I5 and I6, respectively, these being attached to the turning rail 10 or .bar I I at their upper ends while the lower ends are attached to a weight rail or bar I1 common to the series of louvers or slats I3. i

The series of louvers or slats I4 are suspended by inside and outside tapes I8 and I9, respectivel5 ly, these at their upper ends being attached to the rail or bar II while the lower ends are attached to a lowermost or bottom weight rail or bar 20. The louvers or slats I3 of the series are hinged or loosely attached to the tapes I5 and I6 and 20 similarly the louvers or slats I4 are hinged or loosely attached to the straps I8 and I9 in a manner so that these louvers or slats I4 of their series will be closed while the louvers or slats I8 will be open when the turning rail or bar II 25 is in a neutral horizontal plane, thus the lower portion of the blind will be closed while the upper portion will be open. The raising and lowering cords or cables are attached to the rail or bar as is usual, only one of these cords or cables being disclosed and identiiied at I2.

The bar or rail II is angularly adjusted or turned on its axis by the adjusting cord or cable 2i, being manually operated.

Now when it is desired to have the upper and 85 lower series of louvers or slats I3 and I4 disposed angularly in an open position, the rail or bar I I is adjusted to the position as shown in Figure 2 from that position shown in Figure 1 of the drawing.

The rail or bar I I has associated therewith and arranged between the outer tapes I6 and I9 a separator member 22 so that these tapes will not rub upon each other on making adjustment of the upper and lower series of louvers or slats when adjusting the same to the position as shown in Figure 3 of the drawing.

When it is desired to have the upper and lower series of louvers or slats I3 and I4 closed with relation to each other, the blind is adjusted to that position shown in Figure 4 of the drawing, this being brought about by the turning of the rail or bar I I on its axis in a direction to slacken the inside tapes I5 common to the upper series of louvers or slats I3 while the outside tapes I6 65 and I9 will be drawn upwardly in a. taut condition resulting in both series of louvers or slats assuming an angular disposition completely closing the blind.

l i What is claimed is:

In a Venetian blind, superposed series of slats flexibly suspended with one series reversely an- `gled to the other series, whereby on operating the blind one series will close, the other series open or both series close with relation to each other, ilexibl'e suspension means independent of each other for the respective series of slats, and

a rocking bar carrying the suspension means for .5

the series of slats and operating the latter concurrently on the rocking of said rocking bar.l
