VENETIAN BLIND HEAD BAR BRACKET Filed Jan. 13, 1937 INVENTOR.

ATTORNEY.

Patented May 31, 1938 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates generally to brackets and more particularly'to a bracket for supporting the head-bar of a Venetian blind.

An object of the present invention is the provision of a novel bracket structure which is completely reversible so that a single form of bracket may be used to support either end of the headbar by merely reversing the position of the bracket.

Another obj ect of the invention is the provision of novel structure whereby this improved brackct maybe mounted on. any one or more of three surfaces abutting the'bracket.

Another object of this invention is the provi-' sion of single clamping means for detachably securing the head-bar in place regardless of the position of the bracket, that is, whether it is used on the left or right end of the head-bar.

A still further object herein is the provision of a Venetian blind head-bar bracket which is of substantially one piece construction, and which therefore maybe easily and economically manufactured.

Another feature of the invention 'lies in the ease with which the bracket is installed, and the rapidity with which the head-bar may be positively secured or detached therefrom.

These objects and further features and advantages will more fully appear in the progress of this disclosure and as pointed out in the appended claims.

In the drawing forming a part of this disclosure, similar reference characters designate corresponding parts throughout the several views thereof. a

Figure 1 is a fragmentary front elevational view of azpreferred embodiment of the invention as used to support the left end of a Venetian blind head-bar.

Figure 2 is a view similar to Figure 1, but the bracket is shown in reversed position in order to support the right end of the head-bar.

Figure 3 is a side elevational view of the bracket ass-een from the right of Figure 1.

Figure 4 is a plan view of the plane blank from which the bracket is formed.

Figurefi is a perspective view, slightly reduced, of Figure 3.

Referring to Figures 3, 4, and 5, the bracket ID is comprised generally of the side plate II, in.- cluding legs 12 and I3; head-bar supporting lugs 14 and 15; clamping screw supporting lug l6; and. clamping'and attaching lugs ll, l8, l9, and 2D. The side plate II is substantially L shaped and the lugs M to 20 inclusive are all preferably integral with the side plate and bent up perpendicular therefrom.

The clamping screw support lug I6 is positioned at the juncture of the inner edges of legs 12 and. I3 so that the principal surface of said lug is at an angle of 45 degrees with relation to the inner edges of said legs adjacent thereto. Lug i6 is provided with a tapped hole 2| which threadedly carries a machine screw 22. 22 is so positioned that the longitudinal axis thereof bisects the right angle formed by legs l2 and I3.

The side plate II is preferably provided with a plurality of countersunk holes 23, 24, 25, 26, and 27. Holes 23 and 25 are preferably on a line parallel with the outer edge of leg I2, and holes 21 and 25 are preferably on a line parallel with the outer edge of leg 13, thus hole 25 is on a line with the longitudinal axis of screw 22. The holes 24 and 26 are preferably not on a line with their adjacent holes so that when the bracket is affixed to a wooden upright, the tendency of the wood to split is reduced.

The lugs ll, [8, l9, and 20' are preferably each provided with countersunk holes 28, 29, 30, and 3| respectively.

It may be noted at this point in the disclosure, that the leg 12 including its associated parts and orifices is symmetrical with relation to the leg i3 and its associated parts and orifices, and that this symmetry occurs at either side of an imaginary line passing through the longitudinal axis of the screw 22.

As seenin Figures 1 and 2, a door or window frame has vertical portions 32 and a horizontal portion 32 which face the ends and top respectively, of the Venetian blind head-bar 33. Numeral 34 indicates a wall, or window or door casement having a front surface which faces the rear side of the head-bar 33. A slat tilt bar 35 is supported from the undersurface of head-bar 33 by any suitable means such as brackets 36, and the tilt bar in turn supports slat carrying tapes 3?. The slat tilt bar and its related structure is not shown or described in any particular detail because the head-bar 33 may be used to support any known slat tilting or elevating mechanism and the present application is directed to the head-bar supporting bracket.

Turning to Figure 1, where the bracket II] is used to support the left end 38 of the head-bar 33, leg I2 is placed uppermost, and in a horizontal position, while leg 13 is in a vertical position and to the rear. The smooth side of bracket I is placed against the vertical portion 32. It then becomes a matter of choice with the person installing the bracket as to which of the holes, 23 to 3|, inclusive, shall be penetrated by screws to therebysupport and attach the bracket. Factors which will affect this choice will be: the total weight of the Venetian blind carried by the headbar; whether or not there are, in the particular installation, surfaces corresponding to portions 32, 32', or the surface indicated by numeral 34; and what is the particular character of said sur- 'fices) or self tapping screws.

faces. It may thus be seen that this improved bracket is readily adapted to many different conditions of special and usual installations. It is obvious that various types of screws or nails may be used to secure the brackets in place-such as wood screws, machine screws (in tapped ori- Flat headed screws are preferable so that in conjunction with the countersunk holes a flush surface is produced and the head-bar may be slid freely into and out of position on the bracket.

When the bracket i is placed in the position just described, the lug I4 supports the head-bar end 38 in conjunction with the upper end of the screw 22. This support of the head-bar end is diagrammatically illustrated in Figure 3 wherein the head-bar outline is shown in dot-dash lines, and the advanced position of the screw end is shown in dashdoubledot lines. The screw 22 in cooperation with the lugs I1, l8, and I9 forms a clamping device which securely seats the head bar in place in the bracket and aligns it in contact with the inner face of the lugs l8 and I9. Thus the lugs l1, l8, and I9 perform a double function as cooperating mechanism for the clamping screw 22 and as attaching means for the supporting of the bracket. By reason of the fact that the screw 22 approaches the under surface of the head-bar at an angle of 45 degrees, the screw can cut into the head-bar and can force it in a direction having upward and rearward components. Manipulation of the screw 22 is obtained with an ordinary screw driver, but it shall not be considered to be beyond the scope of this invention to substitute a winged, or knurled head for the slotted head of said screw.

Turning to Figure 2, the bracket I0 is shown as used to support the right end 39 of the head-bar 33. Here leg I3 is placed uppermost, and in a horizontal position, while the leg i2 is in a vertical position and to the rear. The bracket I!) now functions exactly as it does when used to support the left end 38 of the head-bar. The various parts are reversed, however. Lug l in conjunction with screw 22 now supports the head-bar end, and screw 22 forces the head-bar toward lugs l8, l9, and 20.

It may now be seen that there has been provided an improved Venetian blind head-bar supporting bracket which satisfies the objects set forth hereinabove.

The foregoing description has been made rather detailed for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
