Application June 16, 1947, Serial No. 754,983

3 Claims. (Cl. 1601 78) This invention relates to Venetian blind tapes.

At the present time Venetian blind tapes which support the slats are usually formed of fabric with narrow staggered straps secured between the two tapes to form a ladder. It is an object of this invention to provide a tape construction which is formed out of flexible plastic material, so that the tape will not wrinkle, and so that thetape may be formed of colored material which will not discolor or fade, and can be easily cleaned.

Another object of this invention is to provide a tape construction of this kind wherein the slat supporting members are struck from one of the pair of tapes and adhesively or otherwise secured to the inner side of the other tape.

In a modified form of this invention, the tape from which the ladder supporting members are struck has secured to the inner side thereof, and between the slat supporting members, a reinforcing fabric tape or ribbon which may have the same or different color of the plastic tape.

With the above and other objects in View, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawing,

Figure l is a perspective view, partly broken away and in section, of a Venetian blind tape construction constructed according to an embodiment of this invention,

Figure 2 is a fragmentary perspective view of one of the tape members from which the slat supporting straps are struck,

Figure 3 is a fragmentary side elevation of the tape construction,

Figure 4 is a fragmentary perspective view, partly in section, of a modified form of tape construction,

Figure 5 is a fragmentary perspective view of a modified form of outer strap.

Referring to the drawing, the numerals I0 and II designate generally a pair of elongated tapemembers which in the present instance are formed out of plastic material. This plastic material may be either transparent or colored, as may be desired.

The tape member II is adapted to have struck or cut therefrom as along two sides and one end of cut portions to form a plurality of slat supporting straps I2 which are formed at their free or cut ends with right angular portions I 3 adapted to be adhesively or otherwise firmly secured to the inner side of the tape member I I.

In practice the right angle end portions I3 01' the slat supporting straps are adapted to be electronically or otherwise secured to the inner side of the tape It. These slat supporting straps are struck from the strap member II in two rows, being staggered from each other.

By providing a plastic tape II from which the slat supporting straps are struck, these supporting members may be more accurately positioned one relative to the other, so that the blind slats will be accurately spaced from each other. In Figure 2 there is shown the blank tape II from which the slat supporting straps I2 are struck.

Referring now to Figure 4, there is disclosed a slightly modified form of this invention wherein the tape member Ila which has the slat supporting straps I211 struck therefrom in two parallel rows spaced apart a slight distance, has secured to the inner side thereof a fabric reinforcing strip or tape I4. This reinforcing strip or tape I4 may be adhesively or otherwise firmly secured to the inner side of the tape member IIa between the two rows of supporting straps I 2a and may be colored the same color as the color of the tape IIa or if desired may be a differentiating color. By providing the reinforcing strip or tape I4, the plastic tape member Ila will be held against stretching in addition to being reinforced to prevent cracking or other injury to the tape member IIa.

With a tape construction as hereinbefore described, the tapes supporting the slats can be more readily thoroughly cleaned than fabric tapes, and through the provision of the plastic material the color will not fade after the tapes have been in use as is the case with colored fabric tapes. These tapes are adapted to be secured to the Venetian blind assembly in substantially the same manner as the fabric tapes, and the elevating and lowering ropes or strings are adapted to engage between the rows of slat supporting members.

With reference to the tape member II shown in Figure 2, which is joined to member ID, as shown in Figure l, a preferred method of joining the straps I2 to member I8 is to place the member I i while in fiat position on top of member I0, then electronically weld the straps I2 to member It). When the ladders or members III are thus joined, absolute accuracy and registry of IO and I! is obtained.

With reference to the reinforcin strip I4 shown in Figure 4 as applied centrally of member I I, it will be understood that similar strips joined in the same manner can be applied along the outer sides of member II as Well as along the longitudinally extending sides of member ll], preferably in such case on the inner side or in brief, the sides of the two tapes I and H which face each other when in assembled relation, as illustrated in Figure 5.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

1. A Venetian blind tape construction comprising a pair of elongated parallel tapes, one of said tapes having two rows of horizontally and vertically spaced apart slat supporting straps cut from said one tape along two sides and one end, the opposite ends of said straps being in tegral with said tape, and said one end of said straps being fixed to the inner side of the other of said tapes to form a ladder-like construction.

2. A Venetian blind tape construction comprising a first elongated tape and a second elongated tape, said second tape having two horizontally spaced apart rows of vertically disposed slat supporting straps cut from said one tape along two sides and one end, the opposite ends of said straps being integral with said tape, and

.4 said one end of said straps being fixed to the inner side of the other of said tapes, each of said straps being spaced vertically from the adjacent straps in the same row and from the adjacent straps in the other row to form a ladder-like construction.

3. A Venetian blind construction comprising a pair of elongated parallel tapes, one of said tapes being formed with two parallel spaced apart rows of staggered slat supporting straps cut from said one tape along two sides and one end, the opposite ends of said straps being integral with said tape, and said one end of said straps being secured to the inner side of the other of said tapes to form a ladder-like construction.
