Hans K'. Lorentzen, Montclair, Nr.1., assignor to LorentzenfHardware Mfg. Corp., New York, N. Y., a corporation of New York y v Application February 14, 1942, Serial No. 430,890` 12 claims. ol. 15e-17) This invention relates to a construction for holding down a Venetian blind when itis fully extended, ,to prevent the blind-fromslapping tially in section and on a larger scale, showing l the bracket and associated parts appearing at in the wind. Embraced within' the invention is a hold-down bracket for mounting on thewindow sill to `hold the blind down.

Various hold-down constructions and brackets are already known, but all of them so far as I am aware involve certain diiiiculties or limitations. Some hold-down brackets are unduly expensive and usually they have to be manufactured in pairs, one right-hand and the other left-hand. Usually the brackets, when mounted and in use, leave objectionable projections which interfere with dusting and cleaning and which are apt to catch the clothing of persons moving close to the window. Except with very expensive types of hold-down brackets they are' not adjust: able to compensate for variations in the length the left-hand side o f Fig. 3L

" Fig. 5 is'a fragmentary front elevation of the.

same type as Fig. 4 but showing the bracket and associated parts appearing at the right-hand side of Fig. 3.

Fig. 6 is a fragmentary vertical section taken in general on line 6-'6 of Fig. 4.

Fig. '7 is a fragmentary vertical section taken ,in generalon line 1-1 of Fig. 5.

The bracket III shown'n Fig. 1 is composed of a single strip of stamped sheet-metal. One end `I I of the strip is formed as a base to bescrewed to the window sill 40 by a screw S (Fig. 6) passing through a hole I6. The body portion I2 of the strip is inclined upwardly and forwardly, and

` the upper end'I4 is formed into a hook that opens of the ladder tapes, and usually the brackets do ,20

not maintain the bottom rail of the blind underproper downward pull.

Objects` ofthe present invention are to provide a Venetian blind hold-down construction which is inexpensive, in which the brackets` are usable both as right and left hand brackets,

which interferes but little'withA cleaning or dusting, and which presents little or nothing that is' apt to catch en ,the clothing of persons moving close to the window. k

Another object of the invention is-to provide a simple inexpensive hold-down bracket that can be stamped as a single piece, of sheet-metal in strip form. g

An additional object ofthe invention is to provide an inexpensive hold-down bracket which is readily adjustable to compensate for a measure of variation in the length of the ladder tapes.

A, still further object of the invention is to provide an inexpensive one-piece hold-down bracket which maintains the bottom rail of a blind under adequate downward pull.

Fig. l of the drawing is an isometric view of a rst form of hold-down bracket embodying the present invention.

Fig. 2 is an i metric view of a second form of hold-down b acket embodying the present invention.

Fig. 3 is a fragmentary front elevation showing the lowerportion of a Venetian blind held downby the brackets of the present invention. For the sake of illustration, the bracket of Fig. l is shown at the left side of the blind, and the bracket of Fig. 2 at the right side of the blind.

downwardly; As shown in Figs. 1', 3, 4, and 6, the strip is transversely arched `in end. portion II and body portion I2 soI that -these portions are convexed upwardly,. thereby adding rigidity` tothe bracket. I l

The bracket 20 shown in Fig. 2 is also .com-

posed of a single stripof stamped sheet-metal.v

One end 2| of the strip is formed as a base to be screwed to the window sill- 4I) by a screw S (Fig. 7) passing through a hole 26. The body portion 22 of the strip is inclined upwardly and forwardly, and the upper end 24 is formed as-a downwardly opening hook. Projecting down- Wardly from base portion 2| is an integral prong 25 that is adapted to project into 'the window sill and prevent rotation of the bracket about mounting screw S.

With either form of the bracket it is mounted by placing the base of the bracket (II in Fig. 1 and 2| in Fig. 2) against the window sill and securing it in place vwith a screw S, as best seen in Figs. 6 and '7. Two brackets lare required for each blind and ordinarily, though not necessarily,

y left-hand bracket, and therefore it is not neces- Fig. 4 is a fragmentary front elevation, par- 55 sary to make them in matched pairs. 'in mounting the brackets they are placed with the bracket strip positioned edgewise of the jambAI, i. e. with the general plane ofthe metal extending perpendicularly to the jamb. Preferably the brackets are placed with theinclinedv body portions (I2 'or 22) extending upwardly and forwardly, and preferably one edge of the bracket is placed directly against the jamb 4I as best seen in Figs. 4 and 5. In this position there is little likelihood of the brackets catching the clothing of a person at the window. Also in this position it is impossible for the brackets to twist about their mounting screws S, but each form of bracket has means to prevent such twisting in cases where the brackets are not mounted directly against the jambs. As previously pointed out, the bracket of Fig. 2 has the'projection 25 which sticks into the window sill and prevents such twisting. The bracket of Fig. 1, due to the uptapes 34, 34 so that gudgeon pins 3|, 3| may` be pushed under the hooks of the hold-down brackets. When the downward manual pressure on bottom rail 30 is released, the ladder tapes retract sufficiently to move the gudgeon pins upwardly where theyjare held by the hooks I4 and 24. As best seen in Figs. 4 and 5, the brackets 2. In a Venetian blind, the blind being mounted in a window frame having a jamb and a sill,

cover and conceal the free ends of the gudgeon pins 3|, 3| whereby they are not left projecting to interfere with dusting or to catch clothing. Also the brackets themselves present little to interfere with dusting or t0 catch clothing.

In making up and mounting a blind it is difllcult to have the ladder tapes so accurately to length that the bottom rail 30 will be a standard distance above the sill when the blind is fully extended. Furthermore, even if the ladder tapes are accurately to the length in the rst instance they usually change in length during use. Ordinarily this change in length is a stretching, but in damp locations it may be a. shrinkage. In the brackets I0 and 20 the body portions I2 and 22 are initially at an angle of about 45 degrees to the horizontal. However, both forms of brackets may be bent upwardly or downwardly as occasion requires to change the elevation of hooks I4 and 24, and thereby to compensate for variations in the distance between the bottom rail and the window sill. Also, the body portions I2 and 22 of the brackets may be suiliciently springy so that in use the brackets always exert a yielding downward tension on the blind.

In compliance with the patent statutes, I have disclosed the best forms in which I have contemplated applying my invention, but it will be realized that the disclosure is illustrative rather than limiting the scope of the invention.
