Abstract

See full text

A window shade system may comprise a drive mechanism having a friction slip ring inside a brake hub, wherein the brake hub is configured to rotate with respect to the friction slip ring, in response to an at least partial rotation of the drive mechanism. The brake hub may be configured to overcome a break-away force between the drive hub and the friction slip ring. The brake hub may be configured to overcome a break-away force between the drive hub and the friction slip ring. The brake hub may be configured to overcome a break-away force of about double a maximum force that a window shade exerts on the friction slip ring. The system may include a spring plunger system abutting a bracket, wherein the spring plunger system may be configured to reduce friction against the bracket in response to a first at least partial rotation of a drive mechanism.
