US Patent 11414927 External motorized actuator for wand-operated venetian blinds

A headrail-mounted motorized actuator for wand-operated venetian blinds has a bracket which attaches to the front of the headrail with a magnet. The bracket has a ferroelectric surface oriented perpendicularly to the headrail. A motor assembly has an output shaft and a second magnet which holds the motor assembly to the ferroelectric surface, so that the output shaft is parallel to the ferroelectric surface. The position and orientation of the motor assembly can be adjusted by moving and rotating the motor assembly on the ferroelectric surface.
