BRACKET FOR VENETIAN BLINDS Filed Aug. 1, 1949 INVENTOR. PAUL J. HARRIS ATTORNEY Patented Sept, 18, 1951 UNITED STATES ATENT. OFFICE BRACKET FOR VENETIAN BLINDS Paul J. Harris, Portland, Greg, assignor to Rite- Hite Corporation, Portland, Oreg.

2 Claims. 1

This invention relates generally to window blinds and particularly to a bracket for Venetian blinds.

The main object of this invention is to produce a bracket for Venetian blinds which will be easy to manufacture, rugged in construction and easy to install and operate.

The second object is to make a bracket which will make pnssible an accurate adjustment of the top rail in order to provide a desired clearance between the lower rail and the window sill.

Attention is drawn to my U. S. Patent 2,332,851, over which this is an improvement.

I accomplish these and other objects in the manner set forth in the following specifications as illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective View of the bracket in a closed or rail supporting position and showing the blind in dotted lines.

Fig. 2 is a perspective view of the bracket showing the apron supporting arm swung out to unlock the adjusting mechanism. Like numbers of reference refer to the same or similar parts throughout the several views:

Referring in detail to the drawing, there is shown a fiat plate l having a lug l I formed along one edge, normal to the plane of the plate [0. The plate l0 and lug II have a number of screw holes I2 and I3 formed therein for attaching the bracket to a frame or casing.

Projecting from the plate ID are the upturned hooks M which are punched out of the metal in the plate In.

Against the plate I0 is mounted an angle plate l5 having a plurality of openings l 6 formed therein, two or more of which can receive hooks M at the same time and effectively position the top leg l1, upon which can rest the top plate 18 of a Venetian blind which, if desired, may be fastened to the le I! by screws passing through the holes IS in the legs IT.

From the plate l8 hangs the cords 20 which support the lowermost rail (not shown). A bracket 2| tiltably supports the top rail 22 which in turn supports the tapes 23, on whose cross ties 24 are supported the blind slats in a conventional manner.

The problem solved by this invention is the accurate adjustment of the elevation of the plate I 8 in order to provide the desired clearance above the window sill.

It is a well-known fact that mounting Venetian blinds is ordinarily a difilcult task, owing to the fact that the blind may vary slightly in length before and after cleaning or under extreme atmospheric conditions.

In my prior patent referred to I employ a screw adjustment which, although providing a fine adjustment, was slow in action and rather expensive to produce.

In the present invention, I. have provided a vertical channel 26 having adapted to receive an apron 2'! between its front edge 28 and lugs 29. An ear 30 projects from the channel 26 and is attached by a rivet 3| to the plate Ill.

In the middle of the channel 26 is disposed a toothed ear 32 capable of engaging the edge of the leg I! between two teeth 33 as shown in Fig. 1. A downturned ear 34 holds the ear 32 against the plate l0 and a pair of center punches 35 and 36 latch the ear 32 in a closed position.

It can be seen that in order to adjust the length of a blind and therefore its clearance above a window sill, it is only necessary to swing the apron 2'! outwardly, thereby releasing the plate l5 and making it possible to raise or lower it at will. Thus it can be seen that the elevation of the bottom rail can be accurately fixed.

I claim:

1. A bracket for Venetian blinds consisting of a fiat plate adapted to be secured to an upright support, said plate having a lug at one side thereof normal thereto, an angle plate movably mounted against said flat plate, said plates having a series of hooks and openings registering with each other whereby said angle plate may be held at a pre-determined elevation, an apron supporting channel having its lower end hinged to the lower end of said flat plate and having a plurality of notches formed in the side thereof adapted to engage said angle plate and fix its position when said apron is in a vertical position.

2. In a bracket for Venetian blinds, the combination of a flat plate having hooks projecting from a flat side thereof, an angle plate having a series of openings registering with said hooks adapted to support said angle plate in a selected vertical position, a channel member having a closed end hinged to one corner of said plate and foldable along one edge of said plate, said channel having a projecting ear provided with slots adapted to receive said angle plate and means for holding said channel ear against said fiat plate.
