Application April 14, 1945, Serial No. 588,361

1 (Jlaim. 1

This invention relates generally to Venetian blinds and particularly to a slat therefor.

The main object of this invention is to provide an improved form of blind slat which will be .readily removable for cleansing purposes, painting, or repairs. v

The second object is to provide a slat of the class described, which will possess all of the strength of the conventional form of slat and without detracting from the appearance thereof.

I accomplish these and other objects in a manner set forth in the following specification as' illustrated in the accompanying drawing, in which Fig. 1 is a fragmentary plan of a portion of a blind slat showing an open cord slot and a wire closure therefor.

Fig. 2 is an edge elevation of Fig. 1. a

Fig. 3 is a transverse section taken along the line 3--3 in Fig. 1.

Fig. 4 is a view similar to Fig. 1, showing a modified form of closure.

Fig. 5 is an edge view of Fig. 4.

Fig. 6 is a section taken along the line'G-Bin Fig. 4.

Fig. '7 is a fragmentary plan of a prior art slat.

Similar numerals refer to similar parts throughout the several views.

Referring in detail to the drawing, there is shown in Figs. 1 to 3 a slat l having a slot ll formed therethrough from one edge H to receive the cord l3. In order to strengthen this slat the corners l4 and I are Joined by a wire clip having the two side members l6 and I I, which are united at one end by the U-shaped member 18 and the opposite ends of the members l6 and I1 having the U-shaped clamps i9 and 20 formed thereon. whose tips 2| are preferably curled backwardly as shown.

The material from which this device is made is I preferably a spring steel wire, which is frictionally held in place by the spring action of the U- shapedmembers l8, l9 and 20. It can be seen that should it be desirable to remove the slat Ill from the cords l3, it is only necessary to slip wardly to occupy the slots H.

. 2 Y the clamps oil of the slat and withdraw it laterally.

In the form of the device shown in Figs. 4 to6, the slat I0 is also provided with a slot ii for the cord-l3 and the mouth of the slot ii is closed by the channel shaped spring clamp 22, whose middle portion 23 is preferably inturned into the slot 5 I to serve as a means for locating the clamp 22 along the slat l, and also to protect the cord i3 from the edges of the metal in the clamp 22. In Fig. '7 there is shown the common form of prior art slat 24, in which the slot 25 does not extend through the side of the slat. That is, his not an open slot. It can be seen that in either of the forms of the device shown in Figs. 1 or 4, the principle employed is the same. the difference being only in the form of material used. In either case, it will be desirable to finish the material in the clamp to correspond with the finish of the slat i0. itself.

It will be noted in Fig. 3 that the intermediate portion 26 of the members l6 and i1 is bent in- The purpose of this construction is to fix the longitudinal position of the device with relation to the slot H.

While I have thus illustrated and described my invention, it is not my desire to be limited to the precise form shown herein, and I intend to cover such forms and modifications of the invention as fall fairly within the appended claim.

I claim: 7

A clasp for blind slats consisting of an elongated channel having the intermediate portion of its upper side inturned to form a closure across a portion of the open side of said channel.
