摘要:
A bail lock for coverings for architectural openings wherein at least one of the bails defines a cord guide surface of changing front-to-back cross-sectional profile so as to define a cord passage between the inner and outer bails that varies from a relatively straight path that allows the cord to pass freely through, to a more tortuous path that applies substantial frictional force to the cord.

摘要:
A modular blind transport system for a window blind application. The complete system may be assembled form a relatively small number of individual modules to obtain working systems for a very wide range of applications, including especially a category of counterbalanced blinds wherein a relatively small external input force may be used to raise or lower the blind, and/or to open or close the blind.
