Abstract
The invention refers to a pull cord arrangement for a roller blind or a venetian blind, comprising a winding element (4) arranged to be connected to a blind (6) such that the blind (6) is released or wound in response to a rotational movement of the winding element (4) about a rotational axis; a connecting element (28) coupled to the winding element (4) to rotate together with the winding element (4); and a pull cord (50) engaging the connecting element (28) so as to control the rotation of the connecting element (28) and thus the winding element (4) as the pull cord (50) is operated.
