6 Claims. (Cl. 160-178).

This invention relates to Venetian blinds, and more particularly to supporting means by which said blinds are raised, lowered or positioned,

In the past, the slats have been supported by means of specially manufactured tapes having two side members with cross pieces woven into each of the side members and forming supporting strips similar to the rungs in ladders. These tapes, because of the structure, had to be woven on specially constructed looms, and the supply thereof was necessarily limited whfle the cost of said weaving material increased the cost of the finished blinds.

An object of this invention is to provide a tape which may be more simply and easily constructed and which will be less expensive, while at the same time performing all of the functions and duties of the woven tape. Woven tapes were likewise objectionable in that they were dirt catchers and could not be cleaned. Moreover, due to the nature of the tapes, the shades and colors were limited. v

One of the purposes of this invention is to provide a washable tape and one which is more readily adapted to'dyes and therefore can be supplied in any desired color or shade.

Other objects and advantages of this invention will appear as the description proceeds.

In the accompanying drawing- Fig. 1 is a side elevation of a portion of a provided with my improved tapes;

Fig. 2 is a cross-sectional view of a portion of the line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a cross-sectional view taken on the line 4-4 of Fig. 2;

Fig. 5 is a view of the cord used as a supporting member;

Fig. 6 is a view of a slightly modified form of my invention;

Fig. 7 is a view of another form of connecting member.

My improved tape I 0 consists of two plies of material H and I2. This material may be cotton or any other woven fabric, and may have a decorative design woven or embossed thereon. I

I have found that a pyroxylin-coated cotton material is well-suited for the purpose, although any coated material may be used.

At spaced intervals the inner ply I2 is provided with holes or openings II which may be reinforced by the eyelets l5. .Preferably the openings ll are two innumber and are equally spaced from the edge of the tape. After the inner ply l2 has been prepared and the eyelets put in, the outer layer ll may then be stitched thereto by the stitching IS. The two tape members l0 and 20 are then connected by means of a series of cords 2|.

The cord 2! is provided with a. pressure-closing clamp 22 adapted to engage and hold the end 23 of the cord. The cord 2| is inserted through the openings l4 between the piles of the tape II and i2 and the clamp member 22 closed to hold the end 23. The clamp member may well be positioned between the plies II and I2 in order to cover it. The cord then forms a rectangular loop 25 between the tapes on which the slat 26 may rest. This is best shown in Fig. 4.

woven tape the cross members or ladder members were woven alternately adjacent each border of the tape so that the cord 21 would be held The. slats 26 are provided with a slot 28 through which the cord 21 is passed, In assembling the in position between the ladder members.

blinds, the slats were placed on the supporting members. 7 cord through the respective ladders to properly position it between them. In my improved constiuction, due to the rectangular loop formed when the slats are placed on the loop' 25, the

cord .may be more readily and quickly threaded through the slots 28 and through the center of the loop 25.

While I have shown the cord as a supporting memberpassed through the openings it, any other suitable device may be used.

In the modification shown in Fig. 6, a wire 30 is bent upon itself to form a loop 3| having a flat end 32. It will be noted that the wires are passed through the holes I and bent upon themselves to form the loop 3| which enables the wire to perform the same function as the more flexible cord. If desired, a split wire may be used with the ends bent upon themselves to pass through the opening I4 and to lie flat between the inner and outer plies.

In the modification shown in Fig. '7, the wire member It! may be used to support the slats. The member 40 has an end 4| bent outwardly so that it may be readily inserted through theholes ll to support the slats.
