Abstract
A vertical blind control includes a single control mechanism for traversing the vanes (8), i.e., opening or closing the blind, and for rotating the vanes to change the amount of light admitted by the closed blind. The control mechanism includes a wand (29), which is used to slide and rotate a shaft (35) carrying opposed bevel gears. One bevel gear (72) is engageable with a mating gear system (76) connected to a tilt rod (10) for rotating the vanes. The other bevel gear (63) is engageable with a drum (48) carrying a cord (13) for traversing the vanes to open or close the blind. The shaft is slidable within the mechanism so that only one of the bevel gears is engaged at any one time to effect the desired operation.
