(57) A cord lock (2) for fitment to the end of a head rail (1) of a blind, the cord lock
including a base element (3), a cap structure (5) on the base element (3) and together
with the base element (3) defining therebetween a cord inlet, a cord outlet and a
cord passage extending therebetween, a cord guide surface (27,29) formed in the base
element (3) and extending inwardly of the cord lock (2) from the cord outlet, a locking
roller (7) and roller guide walls formed in the cap structure defining a path along
which the locking roller (7) may move, the path being adjacent to and inclined with
the cord guide surface (27,29) such that the roller (7) moves closer to the cord guide
surface (27,29) whilst moving away from the cord outlet, wherein with the cord lock
(2) oriented in use such that the roller (7) moves under gravity away from the cord
guide surface (27,29), movement of a cord inwardly from the cord outlet along the
cord guide surface (27,29) will cause the roller (7) to move towards the cord guide
surface (27,29) and pinch the cord therebetween.
