US Patent 11234549 Grommet drapery system

A wirelessly controllable, motorized and battery powered drapery apparatus is presented having a rotatable drive element having a guide structure in its surface. The rotatable drive is inserted through the open interior of a plurality of grommets in the shade material. A grommet driver is positioned over the rotatable drive element and connected to one of the plurality of grommets. The grommet driver has at least one tooth that is in communication with the guide structure in the rotatable drive element. As the rotatable drive element is rotated, the grommet drive is driven along the length of the rotatable drive element thereby moving the shade material between an open position and a closed position.
