This invention relates to a construction, for

holding down a Venetian blind when it is fully extended, to prevent the blindfrom slapping in the wind. Embraced" within the invention is a h-oldadown bracket formounting on the window frame to hold the] blind down, the bracket being adapted for both inside and outside mounting of the blind. Aninside mounting is one in which the blind is nested within the window opening, the hold-down brackets being usually mounted on the sill of the window. An

outside*mounting is one in which the blind is notnested within the window opening; usually the end of the slats overlie the faces of the window jambs, and the hold-down brackets are usually mounted on the face of the window frame which facesthe room. v

Various hold-down constructions and brackets are already known, one form now in extensive usebeing that shown in Lorentzen U. S. Patent 2,298,892 dated October 13, 1942. The holddown 'bracketof thatpatent can be mounted 2 Claims. (01. 2485-267) with-a-ll'parts of the bracket positioned close to the side of a window jamb; and, asicompared; to certain prior brackets, it effected considerable improvement fromthestandpoint of interfering with dusting and cleaning and likelihood oflcatching on the clothing of persons moving close. to the window. However, the bracket of that patent is somewhat more advantageous 'when the blind ismounted inside them it is when the blind is mounted outside.

1A hold-down bracket which is very desirablefrom the standpoint of freedom from any substantial tendencyto snag dusters, wiping cloths,

andclothing, is shown in my U. S. Patent 2A021769 dated June 25, 1946. However with that bracketit is not quite; as easy to insert a mounting, screw through thefoot of the bracket asggit ,is with, the bracket shown in Patent. 2,298,832. ,Also, the bracket of my Patent 2,402,769 has a somewhat unconventional ap pea n ai v, i r i general object of the present invention is to, provide a Venetian blind hold-down construc--,

tion, including a hold-down bracket, which to a considerable degree realizes the advantages of both the bracket of Patent 2,298,892 and the bracket of Patent 2,402,769. 7 Y

Among specific objects of, the invention are to provide .a hold-down bracket which maybe mounted on a window sill with all upwardly,-

projccting portions quite close to the jamb,

haslittle tendency tosnag clothing and cleaning A cloths, which is suitable for both left:

hand and" right-hand mounting, which is advantageous when the blind is mounted outside as well as inside, which is -inexpensive to pro class, which is ruggedin use, and which. may be advantageously manufactured as a one-piece sheet metal stamping. 1

, Further objects, and objects relating to details and economies of manufacture, installation and use will more definitely appearfrom the" detailed description to follo a My invention is clearly defined in the appended claims. In the claims, as well as in the description, parts are attimes identified by specific namesdor clarity and convenience, but such nomenclature isintended to be as generic, in its application to similar parts, as the concept of my invention in relation to the pertinent prior art will permit. The best form in which I have contemplated applying my invention is illus trated in the accompanying drawing forming a part of this specification, in which: l l

Fig. 1 is a fragmentary front elevation showing a window frame with an inside-mounted Venetian blind held down by brackets of the present invention mounted on the sill.

Fig. 2 is a side elevation, partially in section,

showing on a large scale one of the duplicate hold-down brackets shown in Fig. 1.

i Fig. 3 is a front elevation of the bracket shown in Fig. ,2, thecooperating pin of the view of the bracket shown yFigi 6 is a fragmentary sectional View on the v line 6--,-6of Fig. 5, the bottom bar of the blind being indicated in dot-dash lines.

The windowframe t0 shown in Fig. 1 includes jambs at .H, ,l I, the faces of whichextendper-l pendicularly to the plane of the figure; The, bottoms of the jambs are connected by a sill '12. Vertical trim pieces I4, 14 extend across, and

beyond the front edges of the jambs, and ahorportion of thesill. The parts ll,: l2, I4 and I5 are all, considered as being part of the windowr frame.

sill does not, project into the room beyond the plane of; thewall surface, and trim pieces such, as ,;-|4. Jld l51are, omitted.- Such a; window is;

Insome window constructions, the

shown fragmentarily in Figs. 5 and 6; and with such a window, the frame thereof is considered to include a several inch wide wall zone which embraces the window opening.

Suspended inside the window frame I0 is a Venetian blind designated as a whole by IS. The bottom bar or rail H of the blind is provided, by fittings or otherwise, with pins |8, H! which project from the ends thereof perpendicularly toward the faces of the jambs at II, II. Secured to the sill l2 are hold-down brackets l9, l9 which receive the pins and thereby hold the blind down.

The brackets |9, |9 are duplicates, each being of the form shown in Figs. 2, 3 and 14. Each bracket I9 is preferably formed as a one-piece sheet metal stamping. I prefer to stamp the bracket from mild sheet steel, suitably plated or otherwise rust-proofed, either before or after stamping.

The bracket l9 has a base which includes a body portion 2| and an arm portion 2.2 extending therefrom. When the bracket is mounted on a .fiat surface, both the body portion 2| of the base and the arm portion 22 thereof engage the surface on which the bracket is mounted. The base is elongated, havingon opposite sides long edges 24 and 25. Body portion 2| of the base 'is provided with a hole 26 to receive a headed fastener, such as a screw 21 (Figs. 5 and 6), preferably a conventional flat-headed screw. Struck from the base 20 are a pair of prongs 28., 28 which penetrate the surface on which the bracket is mounted, thereby preventing swivel movement of the bracket about the mounting screw 27. Metal surrounding the hole 26 is embossed to form an upstanding annular rib 29. This rib stifl ens and strengthens the base and eliminates the necessity forcountersinking to provide a seat for the tapered head of a flat-headed screw.

Arm portion 22 of the .base 2|? is also embossed to form an upstanding rib 30, this rib merging with annular rib 29. The rib 29 stiffens and strengthens the arm portion 22, particularly in its connection to the body portion 2| vof the base.

One edge of arm portion 22 coincides with edge of thebase. However, the opposite edge of arm portion 22 is aligned with a point substantially half way between edges 24 and 2.5. Extending from this edge of'arm portion 22, and integrally connected with the arm portion, is a flat pin-retaining member 3|.

The pin-retaining member 3| is a fiat pieoeof 'sheet metal extending perpendicularly to the general plane of base 20, the sheet formation of member 3| lying in a lane which is midway between two planes parallel thereto and containing, respectively, edges 24 and 25 of the base. The member 3| is adapted to receive and retain a pin, such aS pin I8, projecting from the end of the bottom bar .of a blind. For this purpose member 3| is provided with a slot 32 as shown, to receive the pin. The slot results in the pinretaining member 3| having a hook portion at 34.

Locating the pin-retaining member 3| as shown midway between edges 24 and 25, imparts to the bracket two advantageous characteristics. Firstly, when mounted 'as shown in Fig. '1, the upwardly-projecting part of the bracket is spaced laterally from the side of the jamb by an amount which is only-half of the width of base 20. secondly, this'spacing is the'same whether edge 24 or edge 25 be placed against the face of the jamb. This not only permits the same bracket to be mounted either on the left-hand or righthand side of the window frame, but permits it to be mounted (on an inside mounting) with the hook 34 either toward the room or toward the window.

Figs. 5 and 6 show the bracket installed for an outside mounting of the blind, the base 20 of the bracket beingsecured to the :face 35 of the window frame, and the pin-retaining member 3| projecting toward the room. In these figures there is indicated a bottom bar 36 in the end of which there is driven a gudgeon pin 31 which is received by the slot-.32.

It will be .noted that whether the bracket be used for an inside mounting or an outside mounting, it will be necessary to depress the bottom bar of the blind, stretching the ladder tapes, before the pin can be inserted into the slot 32. Once the pin is inserted, the ladder tapes resiliently draw the pin to the blind end of the slot, thereby preventing accidental disengagement of the pin fromthe slot.

The bracket can be rapidly and economically stamped in one piece from sheet metal, with a stamped.
