This invention relates to improvements in the construction and operation of supporting brackets in combination with a head bar for Venetian blinds and the like. a

An important object of the invention is the provision in combination with the head bar of a Venetian blind or the like, of a bracket for supporting the head bar and limiting the longitudinal movement between said head bar and bracket.

Other objects of my invention will either become apparent or be specifically referred to in the following description thereof where reference is made to the accompanying drawing, and in which Figure 1 shows the upper left-hand corner of a Venetian blind as the same would appear when equipped with and mounted in my improved bracket and head bar. It will be understood that two such brackets are used in supporting the head 20 bar, one located at each end of the head bar. Inasmuch as the brackets are similar in construction except that one may be described as a lefthand bracket as distimguished from a right-hand bracket, it is believed that an illustration of one of the brackets in combination with the head bar will be sufficient for anyone skilled in the art to understand my invention. I

Figure 2 shows an elevational view of the head bar and bracket shown in Figure 1.

Figure 3 is a sectional view taken on line 3-8 of Figure 2 and looking in the direction of the arrows.

Figure 4 is a plan view as seen from the top of Figure 2. v

Figure. 5 is a development of a piece of sheet metal from which, by means of a series of bending operations, my improved bracket may be formed.

Figures 6, 7 and 8 show details of the bracket formed from the development shown in Figure 5.

Figure 9 is a perspective view of the left-hand end of the head bar shown in Figure 1.

Referring now to the drawing, it will be seen that a head bar 10 is supported at the upper part of a window in a bracket 11. The bracket 11 is formed from a single sheet metal stamping comprising a side 12 and a back 13 bent at right angles to each other. Screw holes 14 are preferably formed in either or both the side 12 and back 13 to provide means for mounting the bracket in any suitable position. A front 15, a top 16 and a bottom 17 all cut integrally from the same piece of metal as the side 12, see Figure 5, are bent along the dotted lines shown in said figure in the same direction as the back 13 and at right angles to the side 12. It will be understood that the back, front and bottom form, in effect, a socket into which the end of the head bar will freely fit and may be longitudinallyadjusted with respect to the bracket. A locking toggle 18, formed integrally with the back 13 and on the edge thereof remote from that at which it joins the side 12, is bent at right angles to the back and toward the front 15, see Figure 8. If desired, screw holes 14 may also be formed-in the top 16.

The head bar 10 of the blind comprises a web 20 having upwardly extending walls 21 and inwardly extending flanges 22 formed thereon by bending the upper edges of the walls toward one another. A screw slot 23, in the front wall 21 and an elongated opening 24 in the rear wall 21, are formed at the left-hand end of the head bar.

' The bracket 11 and head bar 10, as shown in Figures '7 and 9, may be assembled as shown in Figure 2 by lifting the left-hand end of the rear wall of the head bar upwardly through theclearance space 25 located between the front 15 and the bottom 17 and into engagement with the bracket; and thereafter sliding the head bar toward the back 13 of the bracket so that the locking tongue 18 projects through the opening 24 and the slot 23 is disposed over one of the screw holes 26 in the front 15 and the end of the bar rests on the bottom 17, see Figures 3 and 4. When the screw 271s secured in place, but not tightened, it will be understood that the bracket 'may be adjusted longitudinally on the head bar an amount equal to the length of the opening 24 and that a greater adjustment is prevented by the engagement of the tongue 18 withthe ends of the opening 24.

It will be understood that the bracket and head bar construction employed at the right-hand end of the bar, not shown, is similar to that Just described with the result thatwhen the brackets are securely fastened to the window as shown in Figure 1, the blind may bev secured in place by simultaneously elevating the rear wall and the flange of the head bar into position above the bottom piece 1'7 and then pushing the bar into place against the back piece 13. Thereafter any suitable longitudinal adjustment of the bar may be made with respect to the brackets to position the'blind centrally of the window. In a device of this kind the locking tongue 18, projecting as it does across the mouth of the socket, prevents the brackets and head bar 19 from being assembled when the brackets are mounted at a I distance from one another greater than that which would permit the bar to be securely supported by the bracket, because the opening 24 is disposed close to the end of'the bar. Further,

if the brackets are mounted too far apart and one end of a head bar is properly assembled in a bracket, it becomes impossible, becauseof the locking tongue 18, to pull the assembled end of the head bar out of the bracket in an effort to support the otherend of the bar on the other bracket. Hence the combination of a head bar and locking bracket of this kind prevents injury to a person attempting to install a Venetian blind when the brackets are not properly mounted and spaced with respect to one another.

This bracket and head bar combination is also illustrated and described in my copending applicationSer. No. 726,223, filed May 18, 1934.

While I have described what seems now to. be the preferred embodiment of my invention, it is conceivable that various modifications in the configuration, composition and disposition of the component elements going to make up the same as a whole, as well as in the selective combination and application of the respectiveelements may occur to those skilled in the art, and no limitation is intended by the phraseology of the foregoing description or illustrations in the accompanying drawing.

What is claimed is:

1. A Venetian blind bracket comprising means forming a socket in which a head bar is adapted to freely fit, in combination with a locking tongue disposed transversely across the mouth of the socket to prevent the insertion into or withdrawal therefrom of a head bar by a longitudinal movement with respect to said bracket.

2. A Venetian blind bracket comprising a side; and a back, a front, and a bottom all secured to said side and forming a socket in which a head bar is adapted to freely fit; in combination with a locking tongue spaced from the side and projecting transversely, of the mouth of the socket.

3. A Venetian blind head bar formed with an elongated opening proximate an end thereof, in

combination with a bracket for supporting the end of said bar in which is formed the opening aforesaid, said bracket comprising a bottom and a locking tongue extending transversely of the bottom for projecting into the opening in said head bar.

4. A Venetian blind head bar formed with elongated opening proximate an end thereof, in

combination with a bracket for supporting that, end of said bar in which is formed the opening aforesaid, said bracket comprising a bottom, a, front, a back, and means for mounting the same with respect to one'another to form a socket for receiving the end of said head bar, and a locking tongue extending transversely of the mouth oi! said socket, said tongue and opening forming means to limit the longitudinal movement between the head bar and the bracket.

5. A Venetian blind head bar formed with an elongated opening proximate an end thereof, in combination with a bracket for supporting that end of said bar in which is formed the opening aforesaid; said bracket comprising a bottom, a

front, a back, and means for mounting the same bracket, said stamping comprising a side, a front,

a back, and a bottom forming integrally with said stamping, said back comprising a locking tongue formed integrally therewith and projecting in spaced'relationship with respect to said side toward said front, said tongue and opening forming means to limit the longitudinal movement between said head bar and bracket.
