Semi-cordless unbalanced spring driven blind system and methods for adjusting and making same |
摘要 |
The invention includes an unbalanced horizontal blind with a spring means to provide a lifting or retraction force for the slats of the blinds. A brake means prevents undesired movement of the slats that would otherwise result from the continuous retraction force of the spring means when the slats are set in a desired position. Controls for the release of the brake means and tilting are also provided in an embodiment of a blind of the invention. An embodiment of the invention permits the blind to be operated by a single wand that can be used to either raise the slats or tilt the slats. This eliminates the need for a loose cord or bead chain that would traditionally be used as the user interface for controlling the movement of the slats of the blind.
