INSTALLATION BRACKET FOR VENETIAN BLINDS Filed Oct. 5, 1949 INVENTOR Harry 5. Rosenbaum ms Arm/wars I zs la '2524 22 Patented Sept. 21, 1954 UNITED STATES, PATENT OFFICE 2,689,704 INSTALLATION BRACKET EOE VENETIAN BLINDS Harry S. Rosenbaum, Baltimore, Application October 5, 1949, Serial No. 119,684

. 3 Claims. it t 1 This application relates to installation brackets for supporting Venetian blinds. It particularly relates to brackets for supporting blinds having head rails in the form of U-shaped channels in which the operating parts of a Venetian blind, such as tilter rollers, tilters, cord locks, etc., are contained and concealed. Such a head rail'is shown in my copending application Serial No.

22,622, filed April 22, 1948, now Patent No.

Brackets for supporting head rails such as shown in my application above referred to have heretofore been in the form of rectangular sheet metal boxes having one side open through which the head rail channel extends, the ends of the channel resting on the bottom of the boxes. The front of at least one of the brackets is pivoted to open and close the bracket so that the blind can be placed in the brackets after the'brackets have been secured in position. The blind can also be taken. down without removing the brackets. I 1

Since the brackets support the whole Venetian blind, they are subjected to an appreciable weight particularly if the blind is used in a window of more than average height. In addition the brackets are frequently subjected to sudden strong forces when the blinds are raised or lowered or the slats are tilted. Persons operating Venetian blinds frequently give the operating cords rather strenuous pulls generally at an angle from the vertical with the result that they tend to pull the blind not only downwardly but also outwardly from the window. Instances have been known in which the force has been sufficient to spring open the front of the supporting a bracket and the entire blind has fallen from the brackets. It is obviously important, therefore, that the bracket front be held vertically in the bracket as securely as possible. At the same time, however, the front should be readily released so that the entire blind can be taken down for various purposes, such as cleaning.

I have invented an installation bracket in which the front may be locked in position and Which cannot be opened by a pull on the operating cords of the blind regardless of the angle at which the cords are pulled. At the same time the front can be easily released whenever the blind is to be taken down.

In the accompanying drawings I have illustrated a present preferred embodiment of my invention in which Figure 1 is an isometric view of a Venetian blind supported in a window frame by two brackets embodying my invention;

Figure 2 is a side elevation of the bracket looking'in the direction of the arrows AA in Figure 1 and showing the front of the bracket in the closed position;

Figure 3 is a view similar to the view shown in Figure 2 but with the front open;

Figure 4 is a plan view of the bracket shown in Figure 2 with the front closed;

Figure 5 is a bottom view with the front closed; and

Figure 6 is a bottom view similar to Figure 5 but with the front open.

Figure 1 shows a Venetian blind supported by brackets embodying my invention. The brackets designated generally by the reference numbers 6 and l are held by screws 8 to a permanent support such as a window frame, a portion of which 20 is designated in the drawings by the reference number 9. The blind has a head rail which is in the form of a U-shaped channel It], the ends of which rest in the brackets 6 and l. The head rail supports and conceals the operating parts of v the blind such as a tilter roller, tilter, cord lock,

pulleys, etc., only a tilter roller ll being shown in Figure 1. The roller II supports the usual tapes [2 which carry the blind slats l3.

A bracket embodying my invention is shown more in detail in Figures 2 to 6, inclusive. It

comprises a generally rectangular sheet metal box having a top- 14, a bottom [5, a back 16, a front I! and one side 18. The rear wall [-6 may have a slotted indented portion 19 such as is described and claimed in my copending application Serial No. 766,976, filed August '7, 1947. As shown in the drawings, the front I1 is in the form of an angle member, one flange 20 of which lies parallel to the channel it) of the head rail and is shaped to have the same sectional contour as the channel. The other flange 21 of the cover extends at right angles to the flange 20 and carries means for securing the cover in a vertical position as will be hereinafter described The front is pivoted to the side 18 of the bracket adjacent its upper end by a rivet 22 which passes through the side [8 and the flange 2|.

The flange 2| is slotted so as to form a tongue 23 which also extends beyond the end of the flange. The bottom I5 has a slot 24 formed therein at the corner formed by it and the side [8 and extending inwardly from the front edge of the bottom for a distance at least equal to the width of the flange 2| of the front. The slot 24 is increased in width adjacent its end to form a lateral recess 25. The tongue 23 of the front is bent inwardly away from the side l8 as shown in Figure 6 so that when the cover is closed it springs into the recess 25 of slot 24. As is apparent from the drawings, so long as the tongue 23 is in the recess 25 the front of the bracket cannot be opened. After the brackets and head rails have been installed, it occasionally becomes necessary to take the blind down. This can-readily be done by pressing the tongue 23 until it contacts the side I8 and then pivoting the front I1 outwardly and upwardly.

When the blinds are installed a smallclearance is left between the ends of the head rail l and thesides l8 of the brackets. To prevent the head rails from sliding endwise in one direction such as to press against one. of. the ton ues 23 and thus release the front of a bracket, a small lug 2 6 is stamped out of the bottom lot the bracket. This lug is spaced from the end wall .18 at least as faras'the tonguelin when. it is in the recess 25. Ifa head rail shouldslide endwise the. lug 26 will engage the bottom of the U.-shaped headrail and prevent further movementof the rail towards the tongue 23,

From the foregoing description it is apparent that I have invented an'installation bracket for Venetian blinds which provides a secure support for the head rail, against not only the normal weight of the blind-but also strong sudden pullsby persons operating the blind. 'The bracket, however, can readily be opened whenever it is desired ,to-take down the blind. Moreover, the bracket can be manufactured at low cost by stamping from sheet metal.

While :I have described a present preferred embodiment of my invention, it is to be understood that it may be otherwise embodied within the scope of the appended claims.

I claim:

1. An installation bracket for a Venetian blind comprising a rectangular boxopen at one side and adapted to be secured to a fixed support for the blind, the front of. saidbox beingpivotedto the box adjacent-its upper'endand having a tongue adjacent its lower end, a slot in the bottom of the box extending froma side of the box and parallel tothe-front of thebox, said tongue being adapted to spring into saidslot when the front is closed, said box also having a lug extending upwardly from the bottomof the box, the lug being spaced inwardly from the ported in the bracket and the other flange being atright angles thereto, the latter flange being pivoted to the box adjacent its upper end, a
