Application April 15, 1936, Serial No. 74,602-

6 Claims. (G1. 156-17) This invention relates to improvements in Venetian blind tapes of the type illustrated in my gopllegding application Serial No. 726,225 filed May An important object of my invention is to provide, as an article of manufacture, what may be described as single supporting tapes for Venetian blinds as distinguished from the double, or socalled ladder tapes, heretofore used extensively m in the manufacture of such blinds.

Another object of my invention is to provide in combination with single. Venetian blind tapes, slat engaging elements or clip means secured thereto at spaced intervals throughout the length 15 thereof for securing the tape to the edges of the slats of the blind.

Other objects of my invention will either become apparent or be referred to specifically in the following description thereof in which refer- 20 ence is made to the accompanying drawing, and

in which:

Figure 1 is a plan view of a single Venetian blind tape including clip" means secured thereto at spaced intervals throughout the length thereof.

Figure 2 is an elevational view of the tape shown in Figure 1 with the clip. means hanging perpendicularly therefrom. V

Figure 3 is an elevational view of a fragment of a Venetian blind showing a plurality of slats suspended by means of tapes secured to the edge face of the slats by means of clips like those shown in Figures 1 and 2.

Figures 4 and 5 are fragmentary plan views of slat and tape assemblies taken respectively on 35 line 4-4 and 55 of Figure'3 and looking in the direction of the arrows.

It will be understood that aVenetian blind such as referred to herein comprises what is generally described as a head bar mounted in any suitable manner at the top of a window. A series of slats, terminating in a lowermost slat, is suspended from the head bar by any suitable form of flexible members, such as tapes, which are usually secured to an uppermost slat from which all of 45 the other slats are supported. All of the slats and the head bar are perforated to permit the passage therethrough of raising and lowering cords which are secured to the lowermost slat and conducted by guide pulleys to an accessible 50 position at one side ofthe blind. Inasmuch as my present invention relates particularly to supporting tapes having means for securing the same to the edges of the blind slats, it is believed unnecessary to illustrate the complete blind, par- 55 ticularly in view of the following description.

Referring now to the drawing it will be seen, that a series of slats l5 are supported in spaced relationship with respect to one another by flexible members l8 made of any suitable material but preferably fabric tapes or strips as here shown. All of the slats are perforated at I I to permit the passage therethrough of a raising and lowering cord l8. As above stated the slats I 5 are preferably made of thin metal strips stifiened by having the edges thereof bent over with respect 10 to the plane of the strip to form what may be described as an edge face I9 having an efiective width equal to the distance between the plane of the upper surface 20 of the slat and the plane of the lower surface 2| of the portion which is bent over. In the form of slat here shown by way of example the bent-over portion forms a. tubular reenforcing edge at each side of the slat. The formation of this stiffening edge also gives to the slat an appearance of stability from the standpoint of over-all slat thickness to which one'may have become accustomed by viewing blinds having wooden slats which are now in such common use.

The tapes I6 above described comprise a plurality of clip engaging means in the form of spaced tubular loops 26 disposed on one side thereof in any suitable manner, as by being switched to the tape, or woven integrally therewith. It will be understood that the distance between the loops 28 is equal to the desired dis- 3) tance between the slats, see Figure 3.

While my invention may be embodied in other forms, I illustrate in the drawing what I regard .as a preferred form of slat engaging elements,

described-for the want of a better name, as a 5 spring clip 30, by which the tapes it are secured at spaced intervals to the edges of the slats,and in this particular embodiment of my invention to wha have described as the edge face of the slat.

The clip 3|! is preferably made of a piece of spring wire having the ends thereof bent to form arms 3i and 32 and having hooks 33 and formed by bending a portion of the arms inwardly until the ends 35 and 36 of the hooks are spaced a short distance from what may be described as the head or cross bar of the clip. It will be understood that when the clip is bent as described that the parts 30 to 34- are all disposed in the same-plane and that the clip presents a staple-like appearance having a head and two points, 3| and 32. Figures 3, 4 and 5 illustrate how, after the clip .above described isinserted into the tape loops 26',

it maybe pressed into holes 40 and II formed in 'the edge face of the slats. and secured therein 2 by the engagement of the ends as and a with the edged the holes.

Itwill be understood that the proportions of the clips 3. and the size and position of the perforations ll and I are such that when the staplelike ends of the clips are disposedin the perforations the clip may easily be flexed sufficiently to unhook one end thereof so that it can be removed from the perforation whereupon the other end mayberemoved also. I

while thesize of all of the clip means on a tape may, if desired,'be made the same, I prefer to make-the head or cross bar-portion of the clip which is used at each end of the tape enough longer than the others to permit the end 44 of the tape II to be folded between the ends 38 and 34 of the longer clips' so that said ends. 44 may be secured-as shown at ll in Figure 3.

while I have described what seems now to be the preferred embodiments of my invention, it

is conceivable that various modifications in the configuration, composition and disposition of the v component elements going to make up the same may occur to those skilled in' the art, and no limitation is intended by the phraseolosy of the foregoing description or illustrations in the accompanying drawing.

'What is claimed is:

1. A Venetian blindtape of theclast described comprisingin combination a strip of fabric having staple-shaped spring clips secured thereto at equally spaced intervals throughout the length thereof, each of said clips comprising a head and two hook-like point means for detachably engaging in preformed apertures in the edge of a Venetian blindslat, the clips disposed proximate the ends of said tape having a head portion aproximately equal to the width of said tape.

V 2. A- Venetian blind tape comprising a strip of fabric having formed thereon a plurality of space clip oop and a spr c p having a'barportion disposed in each loop, said clips also comprising spaced slat engaging means adapted to enga e yieldably the edge face of a Venetian blind slat when p throu h D forations formed therein.

3. A Venetian blind tape of the class described comprising in combination a strip of fabric having staple shaped spring clips secured thereto at equally spaced intervals throughout the length thereof, each of said 'clips comprising a head and W0 hook-like point means. said point means bein adapted to be inserted into perforations formed in the edge face of a. Venetian blind slat to connect said strip of fabric to said slat. 4. A Venetian blind tape of the class described comprising a strip of flexible material having formed thereon a plurality of spaced clip engaging means and a spring clip adapted to engage a Venetian blind slatdisposed in each clip engaging means, said spring clips comprising hook means adapted to enga said slat through perforations formed in the edge face thereof.

'6. A Venetian blind tape of the class described "comprising'a strip of flexible material having attached thereto at equally spaced intervals a slat engaging element, each said element comprising head means secured to said flexible material and point means projecting from said head means, said point means comprising hook means adapted to yield when pressed through perforations formed in the edge face of a Venetian-blind slat fox-connecting thereto said flexible material.
