Animanga-December 19, 1949, serial No. 13"..2791-e 'f1 lvlyzlinventionrelates toV'enetian blinds, and more. yparticularly..to the. bracket assemblies which support the roller, facia, andoperating mechanism of said blind.

One of the prime objects of my invention is to design a very simple and inexpensive bracket which supports the blinds in position in the window opening, and also provides means for locking the blind at any desired tilted or elevated position of adjustment.

A further object is to provide a bracket which provides for simple means of dsassembling and/or removing the blind for repair, cleaning, or for any other desired purpose.

Still a further object is to provide means whereby a facia board is supported by said bracket, thus concealing the blind operating mechanism from view, and adding greatly to the artistic appearance of the blind.

A further object still is to provide simple and inexpensive locking means incorporated in the bracket, whereby the blind may be operated from either side, and which permits easy locking regardless of longitudinal shifting of said roller.

Other objects and advantages will appear during the course of the following description, it being understood that the invention is not limited to the specific disclosure herein described, but is subject to modification and embodied in various other forms, without departing from the spirit of the invention or the scope of the appended claim.

In the drawing:

Fig. l is a front-elevational view showing the blind mounted in a conventional window casement.

Fig. 2 is an enlarged, transverse-sectional view taken on the line 2-2 of Fig. 1, showing the facia board swung down to permit removal of the roller.

Fig. 3 is a perspective view of the blind bracket only, the facia board supporting means being shown in closed position.

Referring now more specifically to the drawing in which I have shown the preferred embodiment of my invention. the blind as shown is mounted in a conventional window frame F having side frame members 6 and 1 respectively, a window sill easement 8, and a top frame member 9 as usual.

Brackets B are secured to the inner face of the frame members 6 and I byA means of screws (not shown), and inwardly disposed pintle bearings I0 are formed in said bracket for removabllr accommodating the pintles II provided in the 1 elaimlff (c1. 16o-170) ends ofthe operatingl rollerR, and a--slot or passagief-I2 opensto saidl vbearings toA facilitate the mounting of the-roller pintles in. position-.2 i

The roller R is mounted for rotation in the brackets B, and a chain sheave Ill is provided on the end of the roller, a bead chain I5 being trained thereover and hangs within easy reach at the one end of the blind.

Conventional ladder tapes T are looped over the roller R, and slats S are mounted therein. A relatively heavy bottom rail I6 is provided at the lower end of the slat assembly, and elevating cords I1 lare secured to said bottom rail, thence leading upwardly and being wound on the roller R for raising the slat assembly as the roller is actuated.

The roller R can be formed of wood or metal as desired, and is releasably mounted in the brackets B which are formed as clearly shown in Fig. 3 of the drawing, each bracket having inwardly turned end and top flanges I8 and I9 respectively.

A facia board supporting section E! is provided on the front end of the bracket B and is formed with horizontally extending vertically spaced legs 20 and 2|, the lower leg 2li being pivotally secured to the main body at the point 22 to form a hinged connection to permit the member to be swung down as clearly indicated in Fig. 2 of the drawing, the upper leg 2| being accommodated in a slit 23 provided in the flange I9, thus reinforcing said leg in position.

`The outer edge of the section 20 is turned as at 24 to form a ange similar to flange I8, and a shorter parallel flange 25 is spaced therefrom, thus forming a passage of predetermined width therebetween to accommodate a facia board F therebetween, and an inwardly bent lip 26 is provided on the lower end of the flange 24 and forms a stop for said facia board.

Vertically spaced, inwardly projecting comb members 2l and 28 are secured to the lower edge of the bracket B and are formed with downwardly inclined teeth 29 for engagement by the bead chain I5 which is trained over chain sheave I4. This arrangement permits the chain to be engaged from either side of the blind and the plurality of teeth provide for proper chain alignment when the roller shifts longitudinally in the brackets.

In practice, the operation of the blind is as follows. The roller R is actuated by pulling down on the bead chain I5, and inasmuch as the tapes T have frictional engagement with said roller, the slats will be tilted to the desired position, after which the bead chain is swung into interlocking engagement with one of the combs on either side of the blind.

In the event it is desired to raise the blind, the operator pulls down on the chain I5, rotating the roller R and winding the elevating cords Il on the roller to bring the blind to desired raised position, after which the chain is again engaged with-one of the selected combs to holdy it in raised position.

To mount the facia board, it is merely necessary to swing the sections E down to position shown in solid lines in Fig. 2 of the drawing, insert the facia board through the open top of the passage until it bottoms on lip 26, after which the assembly can be swung up as a unit, the leg 2| entering the slit 23; this effectively conceals the roller etc. from View and provides a neat and pleasing appearance.

The entire mechanism is simple, practical and economical; the brackets can be readily mounted, and the entire slat structure can be easily and quickly adjusted and/or raised as desired.

What I claim is:

A bracket for mounting Venetian blinds, comprising a main supporting member and inwardly projecting, horizontally and vertically spaced comb assemblies mounted on the inner face of said bracket, each assembly comprising a plurality of horizontally projecting, downwardly inclined teeth, said assemblies being transversely spaced to permit engagement o f the operating chain on and from eitherside of the blind.
