Although I have described the Venetian blind as being operatable in two sections, it is obvious that three or more sections can be similarly operated, it being only necessary to duplicate the mechanism for operating one of said sections.
Referring more particularly to Figure 7, there is shown a modified form of the invention in which a rear slot 30 is provided in the slat Ila, which slot 30 is open at one end thereof. A 010- sure means, generally indicated as 3| is secured to the edge 32 of the slat Ila, and is pivoted thereto by a pin 33. The closure means 3| is provided with a cutaway portion am to coincide with the rear slot 30. Insucha construction, the ropes 34 can initially be more easily put into position for operation, by swinging the clip 3| open, inserting the ropes 34, and closing the clip.
Second to the cord 34 is a clip 35'which engages '.the"underside of the slat Ila to selectively open or close the same, when the Venetian blind is operated.
Referring to Figures 4 and 5 of the drawing, there is'shown a modified form of the invention, in which a double tape 36 is employed. The double tape 36 is otherwise similar to the tape I9, but is provided with an opening 31 in the upper rear portion thereof, and 'a lower opening 38 in the front portion thereof. The cord 39 enters the aperture 31 and passes between the double tape 36 and extends through the aperture 38. Thus, the major portion of the cord 39 is concealed from view, and generally the Venetian blind has a more attractive appearance. 7
Otherwise, the operation of the modified form ofthe invention'shown in Figures 4 and 5 is identical to the operation of the invention shown in Figure 1. 7
It should be borne in mind that the present invention generally embraces the feature of pro- ?viding a slat for a Venetian blind having two spaced apart pairs of slots, each of which com- ,prises front and rear slotted portions, preferably in substantial horizontal alignment. The invention also, embraces a Venetian blind adapt- .ed to be operated in section wherein pulling' means cooperate with a plurality. of slats to selectively move some of said slats while others remain at rest.
In the operation of the Venetian blind, which forms the present invention, the slatsll are selectively opened or closed by operation of the cord l2. To close a certain ,section of the Venetian blind, in accordance with the present invention, the slats ll are first moved to open position as shown in the upper section of the Venetian blind of Figure 1. With all the slats H in open position, either the'upper or thelower half of the Venetian blind can be se- 1 lective'ly closed by either pulling the cords 2| or 2lb. It should be pointed out however, that the slats mustbe in the open position before they :are adapted for sectional closing. Also,"'onc e a sectionof the slats has beenclosed, and it is desired to open the same, it isnecessary to close all 'sections of the Venetian blind, and then simultaneouslyopen all the'slats through the operation of cord I 2. After the Venetian blind is completely opened, any section thereof may then be selectively closed.
Modified forms of the present invention will --be apparent to those skilled in the art and it is i dsired'to be limited'only by the claims appended hereto.
What I claim is:
1. In a Venetian blind adapted to be operated in sections, a plurality of slats, some of said slats each being provided with center and rear slotted portions intermediate the ends and center of the slat, aligned tapes at the sides of said slats adjacent the slots, the front tapes being provided with an aperture, a pulley carried by the rear tape, and a rope disposed in said rear slotted portions passing over said pulley and through the aperture in said associated tape, and said rope being enlarged at spaced apart portions throughout its length, said, enlarged portions engaging the underside of the said rear slotted portions when said rope is pulled, whereby said some of said slats tilt while the remainder stay at rest.
2. In a, Venetian blind adapted to be operated in sections, a plurality of slats, each of which is provided with center and rear slotted portions intermediate the ends and center of the slat, aligned tapes at the sides of said slats adjacent the" slots, the front tapes being provided with an aperture, a pulley carried by the rear tape, and a ro'pedisposed in said rear slotted portions oisome of said slats and passing over said pulley and through the aperture in said associated tape, and. said rope being enlarged at spaced apart portions throughout its length so that said enlarged portions engage the underside of the said rear slotted portions of some of said slats when said rope is pulled, whereby said some of said slats'tilt while the remainder stay at rest. 3. In a Venetian blind adapted to beoperated in sections, a plurality of slats, some of said slats being provided with center and rear slotted portions,
pulling means cooperating with said'rear slotted portions of said some of said slats to operate the same.
4. In a Venetian blind adapted to be operated in sections, a plurality of slats, some of said slats being provided with center and rear slotted portions in substantial horizontal alignment, rope and pulley means cooperating with said rear slotted portions of said some of said slats to operate the same. i
5. A tape for use in a Venetian blind in combination with a pulling rope, said tape having a front run comprising, a rear portion having an aperture, and a front portion having an aperture spaced from said first mentioned aperture in said rear portion, whereby said pulling rope may enter through the aperture in said rear portion'of the tape and pass between the front and rear portions of the tape to pass through the aperture in the front portion of said tape. 1 Y
6. In a Venetian blind'adapted to'have its slats operated to closed position in sections, a plurality of slats in each section, tapes associated with said slats and having front runs and back runs, a pulley mounted upon the back run of each tape, the front run of each tape having an aperture therein, and a rope havin one end portion passing through the aperture in the front run of each tape and having its opposite end portion passing over said pulley and bein'g operatively connected to each of the slats in one of said sections.
7. In a Venetian blind having upper and lower sections each comprising a plurality of slats, tapes associated with the slats of both sections and having front runs and back runs, a pulley mounted upon the back runs of said tapes adjacent the upper end portions thereof, the front runs of said tapes having apertures in the upper end portions ropes having end "portions. passing through the apertures of the front runs of the tapes and being disposed outwardly thereof, the opposite end portions of said ropes being trained over said pulleys and bein operatively connected with the slats in the upper section of the Venetian blind, whereby the slats of the upper section may be tilted to closed position by pulling on the outer end of said ropes, pulleys mounted upon the back runs of said tapes intermediate the upper and lower ends thereof, the front run of said tapes having apertures disposed intermediate the upper and lower ends of said tapes, and ropes having end portions thereof passing through the intermediate apertures in said tapes and being disposed outwardly thereof and having their opposite end portions trained over said intermediate pulleys, and having operative connections with the slats in the lower section of the Venetian REFERENCES CITED The following references are of record in thefile of this patent:
