Assembly to wind cords in a motorized window covering

Abstract

An assembly for winding cords in a motorized window covering with a headrail having a length suitable for extending between opposite sides of an architectural opening, a winding reel that is substantially in the shape of a tube, a motor that fits substantially within the winding reel, a driver that is rotationally coupled to the output shaft of the motor that allows the winding reel to slide axially with respect to the driver, a threaded adapter that has a threaded segment that is substantially fixed to the winding reel, a threaded fitting that has threads that mesh with the threaded adapter such that the winding reel travels axially as it spins, and a crown that allows the winding reel to slide axially with respect to the crown throughout the winding reel's limits of travel.
