SAFETY BRACKET FOR WINDOW SHADE ROLLERS Filed Aug. 10, 1946 INVENTOR.

BELLA GREEN A TTOIE/VEY Patented Nov. 8, 1949 SAFETY BRACKET FOR WINDOW SHADE ROLLERS Bella Green, New York, N. Y.

Application August 10, 1946, Serial No. 689,720

2 Claims.

The present invention refers to brackets for window shade rollers and refers more particularly to a bracket comprising means for preventing the shade roller from jumping out accidentally.

An object of the present invention is to provide a safety bracket wherein the lock means is positively actuatable into locking and unlocking positions, and frictionally maintained in the position to which it is set. Such a bracket is superior to those in which a locking member is actuated about a pivot, perhaps by gravity alone. The latter type of bracket will fail to function if it is painted or enameled as part of a scheme of decoration, and may even fail to function if lubricated by too heavy a grade of oil.

A further object is to provide a safety bracket similar in appearance to the conventional shade roller bracket without lock means, since the latter is very compact, of pleasing appearance, and already widely accepted.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims inwhich the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a front elevation of a device embodying the present invention, showing the locking member in looking position.

Fig. 2 is a similar view showing the locking member in unlocking position.

Fig. 3 is a side elevation of the same, with the locking member removed.

Fig. 4 is a vertical sectional view of Fig. 1.

Fig. 5 is a front elevation of the locking member.

Referring now in detail to the drawings, the safety bracket I comprises a bracket plate II of substantially rectangular outline and comprising the substantially cylindrical boss I2. Boss I2 may conveniently be hollow and stamped from the material of plate I I, as shown. Boss I2 is formed with a substantially central trunnion opening I3 comprising a throat portion I4 extending radially through the periphery of boss I2 and perimeter of plate II. Holes I for nails or screws permit fastening the bracket to a window frame and the substantially rectangular end portion of a window shade roller spindle may be introduced, through throat I4 into the trunnion opening I3 where it is held against rotation by the shape of opening I3.

The lock member I6 is a substantially three quarter circular ring piece of rigid sheet or plate material I! and comprises a radially outwardly extending handle l8. Boss I2 is slotted as at I9 to accommodate handle I8 in the unlocked position of Fig. 2 and also shown in broken lines in Fig. l. Extending inward radially from plate material I! and located substantially opposite to handle I8 is an auxiliary locking extension I'I which serves to prevent the shade roller from falling out from the trunnion opening I3.

Lugs 20, preferably punched inwardly from the outer surface of boss I2, support lock member I6 to swing in a circular path inside boss I2, and constitute radial bearing means for the said member I6. Equivalent means might be stamped from the body of boss I2.

In operation, with the bracket Ill in the position of Fig. 2, the shade roller spindle, not shown, is introduced into opening I3 through throat portion I4 thereof and the lock member I6 is then grasped by handle I8 and rotated counter-clockwise to the full line position of Fig. 1. ()pening I3 and particularly throat I4 thereof is closed and it is impossible for the shade roller spindle to jump out accidentally, as when the shade is rolled up too fast or otherwise disarranged.

It is notable that in the present invention, the lock member I6 throughout its annular portion I1 is in frictional contact with the interior of boss I2 and therefore will never shake loose from the position to which it is set by handle I8.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A safety bracket for window shade rollers, said bracket comprising, the combination with a bracket plate formed with a hollow boss portion, said boss portion being formed with an opening adapted to receive the substantially rectangular end portion of a window shade roller spindle, said opening comprising a throat portion extending through the periphery of said boss portion, of a parti-circular lock member peripherally slidable within said boss portion about the axis thereof to open and close said throat portion, said boss portion comprising pins located radially interiorly of said lock member and constituting radial bearing means therefor.

2. A shade bracket, consisting of a bracket plate having a struck-out circular boss provided with a shade trunnion receiving slot extending through one side of said boss, said boss being formed with struck-out portions located inwardly of the outer edge of the boss and providing with the outer edge of the boss a circular track, a safety member having an arcuate portion and a slot through one side thereof and a handle extending outwardly of the arcuate portion and a locking element extending inwardly of the handle, the safety member being mounted to turn in said boss against said struck-out portions, the outer wall of the boss having a slot to receive the handle and the locking element being adapted to register with the slot of the boss to confine a shade trunnion therein against displacement through said slot.

BEILA GREEN.
