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 the 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 engageable with a mating gear system connected to a tilt rod for rotating the vanes. The other bevel 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 is engaged at any one time to effect the desired operation.

Commande de store vertical comportant un mécanisme de commande unique pour orienter les lames, c'est-à-dire ouvrir ou fermer le store, et pour tourner les lames afin de modifier la quantité de lumière que laisse passer le store. Le mécanisme de commande comporte une baguette, qui est utilisée pour glisser et tourner un axe portant des engrenages coniques opposés. Un engrenage conique peut engager un engrenage conjugué correspondant relié à une tige pour faire tourner les lames. L'autre engrenage conique engage un tambour portant un cordon servant à orienter les lames pour ouvrir et fermer le store. L'axe peut glisser à l'intérieur du mécanisme de sorte qu'un seul engrenage conique à la fois n'est engagé pour effectuer l'opération souhaitée.
