12 Claims. -(Cl. 248264) This invention relates to Venetian blinds, and more particularly to so-called installation brackets which are afiixed to the window frame for supporting the head-bar of a Venetian blind.

In mounting Venetian blinds it is a common practice to make use of a suspension bar or headbar, which supports a tilt bar and which carries certain mechanism for operating the blind. The head-bar is commonly mounted on brackets placed on opposite sides of the window frame, and it is desirable to provide the bracket with means for supporting a valance which serves to conceal the operating mechanism of the blind. In the case of a so-ca-lled inside mounting of the blind the installation brackets are afiixed to the sides of the window jam bs. In the case of a. so-called outside mounting of the blind the installation brackets are afiixed to the front faces of the jambs.

A general object of the present invention is to so simplify and improve the construction of Venetian blind installation brackets as to effect economies in manufacture and facility of installation, while providing adequate strength and durability.

Another object of the invention is to provide a bracket of the character mentioned which can be economically and satisfactorily made from sheet metal that has received rust-proofing treatment.

Another object of the invention is to provide a sheet metal bracket of the character described which can be rapidly and economically manufactured without welding.

Another object of the invention is to provide a bracket of the character described which has an improved, smoothly operating, locking device for securing the head-bar in position.

A further object of the invention is to provide a Venetian blind installation bracket in which the weight of the supported blind aids in more securely holdin the valance carrier in place.

A still further object of the invention is to provide a Venetian blind installation bracket of such construction that it will have adequate rigidity and strength when made of stamped sheet metal of lighter gage than heretofore used for such brackets.

Various additional objects will be apparent from the detailed description which follows.

My invention is clearly defined in the appended claims. In the claims, as well as in the description, parts are at times identified by specific names for clarity and convenience, but such nomenclature is to be understood as having the broadest meaning consistent with the context and with the concept of my invention as distinguished from the pertinent prior art. The best form in which I have contemplated applying my invention is illustrated in the accompanying drawings forming part of this specification, in which:

Fig. 1 is a plane development of the body member of the bracket.

Fig. 2 is a side elevation of the body member of the bracket.

Fig. 3 is a plane development of a slider used in the bracket to retain the head-bar in position thereon.

Fig. 4 is an isometric View of the slider.

Fig. 5 is a perspective view of the bracket with the valance holder in open position.

Fig. 6 is a vertical section on line 86 of Fig. 7, showing the head-bar, valance, and a portion of the jamb in section, and showing the bracket in side elevation.

Fig. 7 is a section on line 'l'l of Fig. 6.

Fig. 8 is a section of the bracket on line 8-8 of Fig. 6, fragments of the head-bar and valance being indicated in dot-dash lines.

Fig. 9 is a plane development of the valance holder.

Fig. 10 is a side elevation of the valance holder.

Fig. 11 is a section through the valance holder on line Il-ll of Fig. 10.

The drawings show a right-hand bracket embodying the present invention, 1. e., a bracket for supporting the right-hand ends of the head-bar and valance as viewed from the room side of the window. It will be understood that a left-hand bracket also is used with each Venetian blind to support the left-hand ends of the head-bar and valance, and that the left-hand bracket is of the same construction but of the opposite hand.

It is very desirable in brackets for Venetian blinds that they be protected against disfigurement through rusting, but steel which has been bonderized or otherwise rust-prooied does not respond well to spot-Welding for the reason that the protecting surface layer may interfere and 8 of the drawingsg The body memberpf the bracket, designated as a whole by l, is a one-piece sheet metal stamping having a vertical plate pertion 2, a mounting flange l5, and a headbarsupporting shelf 3 which extends horizontally from a depending portion H thatclies 'alongside.of the upper part of the plate portionfli Plate portion .2 2

A valance carrier, designated as a Whole by 2?, (Figs. 10, 11, 9, 5, 6, 8 and '7) is formed as a single sheet metal stamping. It includes a front flange portion 35 and a side flange portion 25 connected by a bend of appreciable radius in zone 26. Side flange 23 is ofiset as shown to provide a shoulder at 29 which, in the closed position of the valance holder (Fig. 8), engages the forward vertical edge of plate 2. A raised circular portion 33 is pressed from the metal of flangetfllifand pierced at-f3 lto receiver-a rivet 36 (Fig; '7) for pivotally attaching the valance holder to plate 2. Also a. rib 31 is pressed from flange 28 to--tsnap behind the foremost rib l of depending body. ,portion .-ll to hold the valance carrier in closed position. Yielding fingers 39, 30 are adapted to engage-the valance 32, top and bottom, and-hold: it against front flange 3|. The valance is 'supported 'at the bottom by a finger 35.

With the bracket assembled as shown in Figs. 5 and G'andmounte'd'in a vertical position on a windowilframe, the slider 28 is elevated to its uppermost position preparatory to receiving a head-bar such as-bal 25.

The valance 3-2 is slid into the carrierrflfrom the open end of the carrierand-yieldable fingers 30, 39 hold the valance snugly against flange 31 despite considerable variation in thickness-of the valance. Since one oiithefingerstil isclosc to finger. 35 there is no danger-of even a very thin valance being forced into such a position that itwill droppast finger 35;. The fingers 3b,- 30 (are pressed out in such manner as toleave the-free edge of flange 23 uninterrupted from bottomtotop. Thus there is no danger of this flange catching onthe forward edgeot-plate 2,- .or straddlingit, as-the valance carrier isclosed.- In'open" position of the valance carrier,-a portion-ofshou1der'29 engages the bottom edge of plate 2 and prevents the carrier 21 from swinging-dowel" than the' position shown in Fig.5

Body-membersd maybe made with the shelf 3-at different levels, toreceive head-bars of different vertical. dimensions. Theflength of rib 31 on the valance carrier is sufiicient-to enable it tosnap behind theforemost-verti'cal rib t on depending :body portion 1 l forthe various commercial levels of shelf 3. Thus, a single size and style of valance carrier suffices for assembly with body members I intended to receive head-bars of different vertical dimensions. The resiliency of depending body portion H is sufficient to hold the valance carrier in closed position unless the valance carrier is forcibly opened. However, the weight of the blind imposed on shelf 3 further presses the lower part of depending portion H against plate 2, thereby aiding in holding the valance carrier in closed position. This is particularly advantageous in the case of wide windows, which require a very long valance board.

Shelf 3 may optionally be provided with upwardly extending burrs or

projections

3a, 3a struck from the edge metal of the shelf, and/or with a hole 31). Burrs 3a, to, when provided embed themselves in the head-bar as shown in Figs. 6 and '7 and effectively resist horizontal shifting of the head-bar on the shelf. To secure the headbar against movement in any direction with respect to the shelf, a screw may be inserted upwardly therein through hole 3b. In this case slider 2!] may, if desired, be omitted.

What I claim is:
