WINDOW COVERING SYSTEM AND WINDOW COVERING CONTROL ASSEMBLY THEREOF
First Claim
1. A window covering control assembly for a window covering system, the window covering system comprises a shell and a weight element under the shell, wherein the weight element is operatively configured to ascend close to or descend away from the shell, the window covering control assembly comprises:
- a driving module provided in the shell and engaged to the weight element to operate simultaneously with the weight element, wherein the driving module comprises a cord collecting assembly, which is mounted in the shell;
the cord collecting assembly is configured to operate in a first direction while a first driving force acting upon the cord collecting assembly such that the weight element descends away from the shell, wherein the first driving force comprises at least a weight of the weight element; and
a speed control module positioned corresponding to the driving module, wherein a resistance force is selectively generated between the speed control module and the driving module, and wherein an operation speed of the cord collecting assembly in the first direction is reduced when the resistance force is generated between the speed control module and the driving module.

Abstract
A window covering control assembly is used in a window covering system. The window covering control assembly comprises a driving module and a speed control module, and is provided in the shell, engaged to the weight element for simultaneous operation therewith. The driving module comprises a cord collecting assembly mounted in the shell. The cord collecting assembly is configured to operate in a first direction while a first driving force acting upon the cord collecting assembly such that the weight element descends away from the shell. The first driving force comprises at least a weight of the weight element. The speed control module is positioned corresponding to the driving module. A resistance force is selectively generated between the speed control module and the driving module, and this force reduces an operation speed of the cord collecting assembly in the first direction.

14. A window covering system, comprising a shell, a weight element, a covering material, at least one lifting cord through the covering material, and a window covering control assembly, wherein the covering material is provided between the shell and the weight element, and one end of the lifting cord is connected to the window covering control assembly, and the other end of the lifting cord is connected to the weight element, wherein the lifting cord controls collection and expansion of the covering material by the window covering control assembly and allows the weight element to descend away or ascend close to the shell, wherein the window covering control assembly comprises:
-
a driving module provided in the shell and engaged to the weight element to operate simultaneously with the weight element, wherein the driving module comprises a cord collecting assembly, wherein the driving unit and the cord collecting assembly are engaged to move simultaneously, wherein the cord collecting assembly is mounted in the shell, wherein one end of the lifting cord away from the weight element is connected to the cord collecting assembly;
the cord collecting assembly is configured to operate in a first direction which releases the lifting cord while a first driving force acting upon the cord collecting assembly such that the weight element descends away from the shell and the covering material expands, wherein the first driving force comprises at least a weight of the weight element; anda speed control module positioned corresponding to the driving module, wherein a resistance force is selectively generated between the speed control module and the driving module, and wherein a rotating speed of the cord collecting assembly in the first direction is reduced when the resistance force is generated between the speed control module and the driving module such that a descending speed of the weight element is reduced. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
