Apparatus for operating horizontal blinds or shades and vertical blinds comprising:
- actuating means coupled to said blinds or shades for selectively moving the same;
- an elongated spiral wand coupled to said actuating means having a plurality of actuators in spiral engagement therewith, one of said actuators being disposed above the other and each actuator having a one-way bearing assembly mounted therein, the bearing assembly in one actuator rotating in a direction opposite that of the bearing assembly in the other actuator, each of said bearing assemblies being in driving engagement with at least one drive nut encircling said wand and in spiral engagement therewith whereby movement of one actuator along said wand rotates said wand in one direction and movement of the other actuator along said wand rotates said wand in a direction opposite that of the said one actuator.
Apparatus for operating horizontal blinds or shades and vertical blinds comprising:
- actuating means coupled to said blinds or shades for selectively moving the same;
- an elongated spiral wand coupled to said actuating means having at least one actuator in spiral engagement therewith, said at least one actuator having a one-way bearing assembly mounted therein, the bearing assembly in said at least one actuator rotating in a single direction, said bearing assembly being in driving engagement with at least one drive nut encircling said wand and in spiral engagement therewith whereby movement of said at least one actuator along said wand rotates said wand in one direction.
