Benefits of technology

The window covering motorized lift and control system described in the patent is a low-cost, efficient and reliable system for controlling the operation of window coverings. It uses plastic gears, which provide cost and noise benefits, and a high speed motor with multiple gear stages for speed reduction. The system is compact and includes a magnetic encoder for braking. Sensors can be incorporated into the bottom rail of the window covering or a hand held user input device for improved performance and reliability.

Problems solved by technology

For increased strength, helical plastic gears and gear train components are used, and the structural arrangements and configurations of the components overcome thrust loading and other forces that have made the use of small plastic helical gears unsuccessful in the past.

Embodiment Construction

[0051]Referring now to the drawings more specifically, and to FIG. 1 in particular, a window covering 100 is shown on an architectural opening 190, such as a window. Window covering 100 includes a head rail 102, a bottom rail 104 and window covering material 106, such as a fabric material as shown in the exemplary embodiment, extending between head rail 102 and bottom rail 104. It should be understood that the mechanism and system to be described hereinafter can be used on window coverings of various types, and the specific type shown is merely one example. For example, the mechanism and system disclosed herein can be adapted for use on various types of horizontal blinds and shades to move the blind or shade vertically, as well as on vertical window coverings such as drapes to move the window covering horizontally.

[0052]As shown in FIG. 2, window covering 100 includes lift cords 108 for raising and lowering window covering material 106, two such lift cords 108 being shown in the dra...

Abstract

A window covering includes a movable window covering material, cords for moving the window covering material, and a motorized lift assembly. The motorized lift assembly includes a motor assembly including a motor, a gear train driven by the motor for adjusting positions of the cords, and an operating and control device mounted to a portion of the window covering for operating the motor in response to user input.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a national stage entry of International Patent Application Number PCT / US2014 / 028234, filed Mar. 14, 2014, which claims the benefits of, and priority to U.S. Provisional Application Ser. No. 61 / 792,226, filed Mar. 15, 2013, the contents of which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to window coverings, and, more specifically, to motorized window coverings and the operating systems provided therefor.BACKGROUND OF THE INVENTION[0003]Motorized operating systems have been provided for window coverings of various types. Often the systems have been expensive and somewhat difficult to install, prepare for use and operate. Known systems have been noisy and large in physical size. Many are relatively inflexible, being factory programmed for specific operations and performance, while enabling little, if any user input, adjustment or alter...
