Regulation mechanism for a venetian blind

A control mechanism for a blind suspended by lift cords, said control mechanism comprising a hollow rod articulated to the headrail and accommodating said lift cords extending to an elevation assembly operated by an actuator slidingly received over the rod;

• wherein upward displacing of the actuator entails lowering of the blind and downwards displacing of the actuator entails raising of the blind, said control mechanism further comprising a friction mechanism for arresting the blind at any respective elevation and a regulation mechanism configured for selectively setting the extent of displacement of the actuator based on the weight of the blind.

A Venetian blind suspended from a headrail by lift cords collectable within said headrail by spools, and a control mechanism comprising a hollow rod articulated to the headrail and accommodating said lift cords extending to a lead bar coaxially displaceable within the rod, an actuator slidingly received over the rod and engaged with the lead bar;

• wherein upward displacing of the actuator entails lowering of the blind and downwards displacing of the actuator entails raising of the blind, and a friction mechanism for arresting the lead bar within the rod at any respective location.
