Braking mechanism for a roller shade controller, control mechanism comprising same and control handle

A control mechanism for a roller shade, the control mechanism comprising:

• a tubular core onto which the roller shade is wrappable, the tubular core being rotatable in a winding direction or an unwinding direction;
• an actuation assembly comprising an actuation member, the actuation assembly being operable to rotate the tubular core in the winding direction or the unwinding direction;
• and
• a braking mechanism operatively connected to the actuation assembly, the braking mechanism comprising:
• a stationary member;
• a rotating member rotatable relative to the stationary member, the rotating member being operatively connected to the tubular core to be rotatable in the winding direction or the unwinding direction simultaneously with the tubular core;
• and
• a connecting assembly operatively connecting the stationary member and the rotating member, the connecting assembly frictionally engaging the rotating member when the rotating member is rotated in the unwinding direction and being frictionally disengaged from the rotating member when the rotating member is rotated in the winding direction.
