SAGINAW, MICHIGAN, A CORPORATION OF NEW YORK SELF-LOCKING- (DMBINAT'ION VENETIAN BLIND BRACKET Application filed September 9, 1929. Serial No. 891,184.

r This invention relates to Venetian blinds, and more particularly to a combination self locking bracket, by means of which the blind supporting bar is removably held in pos1- tion. 1

The prime object of the inventlon 1s to provide self locking brackets, so that the as 'sembled blind may be, easily and readily set.

operation, thereby lending itself to quantity production, and economy in manufacture.

With the above and other objects in view, the present invention consists in the COIIlblnation and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawing: Fig. 1. is a fragmentary view of a Venetian blind showing my improved brackets in po-' sition.

Fig. 2. is an enlarged side view of one of the brackets, the dotted lines indicating the supporting bar. 1

Fig. 3. is a front view, the dotted lines showing the shifting of the end of the locking lever preparatoryto unlocking.

Fig. 4. is a view similar to Fig. 2 with the bracket in unlocked position.

Referring now particularly to the drawing, the Venetian blind includes a plurality of slats 5 suspended from a tilting bar 6,'which is tiltingly supported upon a supporting bar 7 in any approved manner, the ends of this bar semble, and which can be a punch and die being detachably mounted in brackets 8 and 9 respectively, and-it is to these brackets that this invention is broadly directed.

In my preferred construction these bracketsare preferably formed of sheet metal so that they maybe made by a punch and die operation, and inasmuch as both brackets are formed identically alike, I shall describe the construction and operation of but one bracket only.

In practice the brackets are formed angular in shape, the upper end 11 of the back wall 10 being bent horizontally as shown. A substantially horizontal shelf '12 is spaced from the top of the structure, projecting inwardly from the side wall of the bracket, and is formed by bending certain sections 13 and 14 of the side wall inwardly and downwardly, forming a vertically projecting leg 15, which forms the end wall, the upper end 16 of this leg 15 being turned inwardly, and together with the leg 11, engages the top of the supporting bar to prevent the bar being lifted from the bracket.

The end 17 of the shelf is bent downwardly, and is notched as shownat 18 to form a catch for the locking member 19 which engages therewith when the bracket is looked, a lip 20 being provided on the edge of the bracket, said lip serving as a stop to limit downward travel of the member. I

The locking member 19 is pivotally connected to the bracket by means of the rivet 21, the rear end 22 being bent at right angles to the main body, and projects above the face of the shelf, the front end 23 being also bent at right angles, and also projects above the shelf, the upper end being bent to form a thumb rest 24 to facilitate manipulation thereof, said lever being slightly bowed intermediate its length to frictionally engage the bracket, and so that the front end seats in the notched portion 18 of-the lip. To release, this rest 24 is pressed outwardly as shown in dotted lines in Fig. 3 of the drawing, and then downwardly to position as shown in Fig. 4. The inner end of the lever is bent as shown at 25, and when the lever is moved outwardly and downwardly, the upper section of the inner end will force the supporting bar outwardly I in the bracket, and to position as shown in Fig. 4, so that it can be readily grasped by the workman. Replacement of the supporting barmeans merely inserting the back edge of the bar in the brackets, forcing the bar back against the rear end of the locking member, continued pressure automatically moves the locking member to locked position.

Openings 26 are provided in the back and side wall of the bracket, and screws, (not shown) are used to secure the bracket in position. 1

From the foregoing description it will be obvious that I have perfected a very simple, practical, and substantial combination self locking bracket for Venetian blinds.

What I claim is 1. A combination bracket forremovably holding a supporting bar, and including a locking member pivotally mounted on the bracket and formed with upwardly extending end sections adapted to engage the sides of said supporting bar when the bar is mounted in the bracket.

2. A combination bracket for removably holding a supporting bar, a horizontal shelf on the bracket, a locking member pivotally mounted on the bracket below the shelf, and end sections on the locking member for engaging the sides of the supporting bar when the bar is mounted in the bracket.

3. A combination bracket for removably holding a support-ing bar, said bracket having a horizontal shelf, a locking member pivotally connected near its inner end to said bracket, and vertically disposed end sections on said locking member for engaging the sides of the bar.

4. A combination bracket for removably holding a support-ing bar comprising a horizontal supporting shelf, inwardly turned sections for engaging the top of the bar, a locking member pivotally connected to said bracket, means on said member for forcing the bar outwardly when the locking member I a is shifted to' unlocked position.

6. A combination bracket for removably holding a supporting bar, a shelf on the bracket, and a locking member for automatically e ecting said bar when said member is shifted to unlocked position. v

7 i A combination bracket for removably holding a supporting bar, a locking member ivotally mounted on said. bracket and having frictional engagement with the bracket, meanson the locking member for ejecting said bar as the locking member is shifted to unlocked position, and means for locking said member in position.

8. A combination bracket for removably holding a supporting bar, a shelf on the bracket on which the bar is mounted, a locking member pivoted to the bracket and frictionally engaging the side wall thereof, said member having upwardly extending end sections adapted to engage the sides of the supporting bar, and means for holding said locking member in locked position. I

9. A combination bracket for removably holding a supporting bar, said bracket being formed with overhanging sections adapted to engage the top of said bar, a shelf spaced from said overhanging sections, a locking member pivoted to the bracket at a point adjacent the inner end thereof, means on the locking member for engaging the sides of the bar, and means for holding said member in locked position.

10. A self locking combination bracket for removably holding a supporting bar, a shelf on the bracket, and a locking member pivotally mounted on said bracket and adapted to be engaged by the supporting bar for locking said bar in position when the bar is inserted insaidbracket.

11. A self locking combination bracket for removably holding a supporting bar, 8. Sup port on said bracket, and a locking member adapted to be engaged by said bar, said bar shifting said locking member to locked position when the bar is inserted in the bracket.

12. A self locking combination bracket for remivably holding a supporting bar, a support formed integral with the bracket, a. looking member adapted to be engaged by said bar, said bar automatically shifting it to locked position as the bar is inserted in said bracket, and means for holding said locking member in locked position.

In testimony whereof I hereunto aflix my signature.

FRED J. BURNS.
