CONTROL FOR A VERTICAL BLIND

摘要

A vertical blind control includes a single control mechanism for traversing the vanes, i.e. opening or closing the blind, and for rotating the vanes to change t he amount of light admitted by the closed blind. The control mechanism includes a wand, which is used to slide and rotate a shaft carrying opposed bevel gears. One bevel gear is enga geable with a mating gear system connected to a tilt rod for rotating the vanes. The other b evel gear is engageable with a drum carrying a cord 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 i s engaged at any one time to effect the desired operation.
