May 30, 1950 v. E. EDMONDS VENETIAN BLIND 2 Sheets-Sheet 1 Filed Oct. 9, 1945 INVENTOR EDMONDS ,0 A?

VERNE ATTORNEY May 30, 1950 v. E. EDMONDS VENETIAN BLIND 2 Shets-Sheet 2 Filed Oct. 9, 1945 1 5 2O INVENTOR VERNE E, EDMONDS ATTORNEY Patented May 30, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to improvements in Venetian blinds and has for its principal object the provision of means for quickly and conveniently detaching the slats of the blinds from the conventional lifting cords and tapes so that the slats may be washed and replaced upon the tapes without the necessity of dismantling the entire blind and rethreading the lifting cords through the slats as heretofore.

A further object of the invention is the provision of means for strengthening the end portions of each slat which extend outwardly from the lifting cords.

These and other objects will appear as my invention is more fully hereinafter described in the following specifications, illustrated in the accompanying drawings and finally pointed out in the appended claim.

In the drawings:

Figure 1 is a fragmentary perspective view of a Venetian blind made in accordance with the invention.

Figure 2 is a sectional view taken approximately on the line 2-2 of Figure 1.

Figure 3 is a perspective detail view of a spring clip.

Figure 4 is a fragmentary plan view of a slat showing a modified form of clip applied thereto.

Figure 5 is an enlarged sectional view taken on the line 55 of Figure 4.

Figure 6 is a perspective view of a modified form of slot re-enforcing means, and a spring latch applied thereto.

Figure 7 is a fragmentary plan view of Figure 6 with a portion broken away for convenience of illustration.

Figure 8 is a fragmentary plan view of a slat having the form of slot re-enforcement shown in Figure 6 with a spring clip applied thereto.

Figure 9 is a sectional view taken on the line 9-9 of Figure 8.

Figure 10 is a fragmentary perspective view of a modified form of slat preferably made of plastic material or the like.

Figure 11 is a fragmentary view of a further modified form of slat made of yieldable material.

Figure 12 is a view similar to Figure 11 showing the end portions of the slat distorted to allow entrance of the lifting cord into the slot.

Referring now more particularly to the drawings:

In Figure 1, reference numeral I indicates the conventional lifting cords and 2 the conventional suspension tapes having the usual supporting tapes 3 extending therebetween. The slats indicated at 4 are provided with the slot 5 opened at one of its ends as at 6 to receive the cord I. By this arrangement the slats may be swung upwardly until the cord is outside of the slot whereupon the slat may be withdrawn from the tapes. When relatively thin wooden slats I are used, I provide a bifurcated spring clip 8 to embrace the slat around the slot as shown to prevent breakage of the end portion in the direction of its length.

The form of slat shown in Figure 4 and indicated at 9 may be of thin sheet metal or plastic. Along both sides of the slot EU I form parallel stiffening ridges H to receive the corresondingly grooved leg portions l2 of re-enforcing clip l3.

In Figure 6, the slat M is slotted as at [5 and entirely around the slot, I attach, by means of rivets IE or the like, a ire-enforcing element ll of channel section. At the outer ends of the leg members of the re-enforcing element, I attach by means of a pin it? a spring 19 adapted to be pressed inwardly to allow passage of the lifting cord I into or out of the slot.

In Figure 8 the slat is reinforced as at 20 in the same manner as the slat shown in Figure 6, but instead of the latch shown therein, I provide a bifurcated spring clip 2| which grips the top and bottom surfaces of the reinforcing element.

The form of slat shown in Figure 10 is formed with a slot 22 closed at both of its ends as shown and formed with an opening 23 extending to the outermost edge of the slat for passing the lifting cord into and out of the slot.

The slats shown in Figures 11 and 12 are preferably made of flexible material, and the slot 24 therein communicates with the outermost end of the slat by a slit 2 4 so that the end portions may be distorted as shown in Figure 12 to allow passage of the lifting cord into and out of the slot.

While I have shown a particular form of embodiment of my invention, 1 am aware that many minor changes therein will readily suggest them selves to others skilled in the art without departing from the spirit and scope of the invention. Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

In a Venetian blind having a plurality of slats movable vertically by lifting cords, the combination of open ended slots in each of said slats to straddle the lifting cords, U-shaped re-enforcing means of channel section fitted within the slot and secured to the edges thereof, and a U- shaped spring clip removably attached to the open end of the said reenforcing means for closing the same, two sides of said' clip being formed with opposing depressions for guidance between the sides of said U-shaped reinforcing means.

VERNE E. EDMONDS.
