Application April 19, 1944, Serial No. 531,794 Claims. (Cl..160 -178) This invention relates to Venetian blinds and it is one object of the invention to provide blinds of this type which are so constructed that two or more may be used at a window, one above another and independently adjusted. It will thus be seen that by installing upper and lower blinds, one above another, passage of light through an upper sash or a lower sash may be regulated independent of each other and glare eliminated without unduly darkening a room.

Another object of the invention is to provide the Venetian blinds with slats carried by supporting strips located at ends ofth'e slats instead of in spaced relation to their ends. Therefore, the vertically extending strips or tapes carrying the slats will be'dispo'sed adjacent opposite side portions of a window frame instead of in front of the sashes and will not interfere with a clear and unobstructed view through a window. When drapes are in use they will cover the supporting tapes and conceal them from View.

Another object of the invention is to so mount the slats that they are fastened to cross tapes carried by the supporting tapes, the supporting tapes being secured to tilting slats at upper and lower ends of the blinds and causing all of the slats to be tilted together when the supporting tapes are shifted upwardly or downwardly.

Another object of the invention is to provide slats which are firmly but detachably held to the cross tapes by resilient clips, thus permitting the slats to be removed for cleaning or repairs and then easily replaced and secured.

Another object of the invention is to provide Venetian blinds which are simple in construc-' Figure 2 is a fragmentary side view showing the slats tilted to an inclined position;

Figure 3 is a fragmentary view showin some of the slats and one of the supporting strips or tapes partially in front elevation and partially in section;

Figure 4 is a side view showing a portion of the Venetian blinds upon an enlarged scale, the

view being taken along the line 4-4 of Figure 3;

Figure 5 is a fragmentary sectional view taken along the line 55 of Figure 3;

Figure 6 is a top plan view of one end portion end portion of Figure 12 is a view showing the slat'in longitudinal section and the clip applied thereto.

This improved Venetian blind consists briefly of a multiplicity of slats I, upper and lower tilting slats 2 and 3 which may be termed head slats, supporting strips or bands 4 carrying cross strips 5 to which the slats I are secured. by resilient 'clips 6, and brackets 1 by means of which the head slats are tiltably mounted across a window.

The head slats or tilting slats 2 and 3 are of appreciably greater thickness than the slats I and may be formed of wood, plastic, metal, or other suitable material while the slats l are formed of sheet material which may be sheet metal, wood, plastic or the like and are of concavo-convexed formation in cross section, as

shown in Figure 4, with their concaved surfaces presented downwardly.

The head slats have pintles 8 projecting from their ends which engage through openings formed in the brackets l to tiltably mount the head slats, and side edge faces of these head slats are rounded, as shown in Figure 9, so that wear upon the bands or strips 4 will be reduced to a minimum.

The bands or strips 4 are formed of fabric and are endless, as shown in Figure 2, and. referring to this figure, it will be seen that the bands are trained about the slats l and the head slats 2 and 3 in close contacting engagement with the head slats. Therefore, when one of the bands is grasped and vertical shifting movement imparted to it, the cross slats will be simultaneously turned axially of theirpintles. The cross strips 5 extend between front and rear flights of the bands 4 where they are secured in any desired manner, and the slats I are of such width that when they are set in place their side edges will make contact with inner surfaces of the front and rear flights of the bands. The clips 6 are then applied and since the clips are resilient they exert pressure upon the slats and the cross strips and impart a stretching action to the cross strips and cause the slats l to be so mounted that they tilt with the head slats.

The clips are of duplicate construction and each is formed from a strip or strand of resilient metal which is bent substantially midway its length to provide an arcuate bridge portion 9 and arms H] and II spaced from each other as respective cross bands; means detachably securing the end of one of the slats to the associated cross band at the transverse center of the slat.

The arm I0 is bent in spaced 7 relationeto'its freeaend to formianlinwardlyextending -.y shap-e d spur v:jor teeth t2 l andz the Eslats i are formed near their ends with openings or perforations l3 in which the spurs or teeth- 12 v engage to hold the clips in place and prevent the slats I from shifting longitudinal] engagement with the cross strips-5.

If the slats l are not formed with ppenings 13 the clips may be turned to dispose their arms [0 lowermost, as shown in-Fi-g'ure 12, and the.

teeth l2 will then engage against inner side edges of the Supporting-strips and prevent the clips from 'slippirlg out ofengagement with the slats and the cross strips upon which the slats 'rest.

The

fact that thebands are opposite side iportions of the "window frame also permits :them to be i coveered andi concealed by draperies hung along the side portions of a window.
