VENETIAN BLIND HEAD BAR'BRACKET
Julius Nisenson, Brooklyn, N. Y.
Application January 13, 1937, Serial No. 120,374
8 Claims. (Cl. 156-47)
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 pro
vision of a novel bracket structure which is com
pletely reversible so that a single form of brack
et may be used to support either end of the head
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,
ct maybe mounted on. any one or more of three
holes 21 and 25 are preferably on a line parallel
with the vouter edge of leg 13, thus hole 25 is on
a line with the longitudinal axis of screw 22.
15 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 manu
factured.
Another ‘feature of the invention 'lies in the
25 ease with which the bracket is installed, and the
rapidity with which the head-bar may be posi
and 27.
Holes 23 and 25 are preferably on a
line parallel with the outer edge of leg I2, and
The holes 24 and 26 are preferably not on a 15
line with their adjacent holes so that when the
bracket is affixed to a wooden upright, the tend
ency 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 20
3| respectively.
It may be noted at this point in the disclosure,
that the leg 12 including its associated parts
and ori?ces is symmetrical with relation to the
leg i3 and its associated parts and ori?ces, and 25
that this symmetry occurs at either side of an
tively secured or detached therefrom.

Figure 4 is a plan view of the plane blank from

Figure? is a perspective view, slightly reduced,
of Figure 3.
Referring to Figures 3, 4, and 5, the bracket
50 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 in
tegral with the side plate and bent up perpen
dicular therefrom.
The clamping screw support lug I6 is posi
tioned at the juncture of the inner edges of legs
60 12 and. I3 soithat the principal surface of said
portion 32’ which face the ends and top respec
tively, of the Venetian blind head-bar 33. Nu
meral 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 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 40
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 45
used to support the left end 38 of the head-bar
33, leg I2 is placed uppermost, and in a hori
zontal position, while leg 13 is in a vertical posi
tion and to the rear.
The smooth side of brack
et I0 is placed against the vertical portion 32. It 50
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. Fac
tors which will affect this choice will be: the total 55
weight of the Venetian blind carried by the head
bar; 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 60

faces. It may thus be seen that this improved
bracket is readily adapted to many different con
ditions 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
'?ces) , or self tapping screws. Flat headed screws
are preferable so that in conjunction with the
countersunk holes a flush surface is produced and
10 the head-bar may be slid freely into and out
of position on the bracket.
When the bracket i0 is placed in the position
just described, the lug I4 supports the head-bar
end 38 in conjunction with the upper end of the

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 dash—double—dot lines. The screw 22 in
20 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 con
tact 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 meansv for
the supporting of the bracket. By reason of the
fact that the screw 22 approaches the under sur
face 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 ob
tained with an ordinary screw driver, but it shall
not be considered to be beyond the scope of this
35 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
40 horizontal position, while the leg i2 is in a verti
cal 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 l5 in conjunc
45 tion 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 provid
ed an improved Venetian blind head-bar support
50 ing bracket which satis?es 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
55 therefrom, but the appended claims should be
construed as broadly as permissible in view of
the prior art.
I claim:
1. A reversible Venetian blind head-bar sup

formed by said clamping and attaching lugs; and
a pair of head-bar supporting lugs, one of said
head-bar supporting lugs being parallel to and
spaced from one of the said attaching lugs, and
the other one of said supporting lugs being par
70 allel to and spaced from the other attaching lug.
2. A Venetian blind head-bar supporting brack
et having clamping means adapted for rectilinear
movement toward or away from a head~bar
placed in said bracket and adapted to engage the
same, the direction of said movement being less
than 90 degrees with relation to the under hori
zontal surface of said head bar.
