A cord guiding device (20) for a window blind (2) includes a wheel holder (3), a guiding wheel (4) and a cord-blocking unit (5). The guiding wheel (4) is rotatably mounted on the wheel holder (3), and includes two protruding flanges (42) that are spaced apart from each other, and has a wheel surface (43) that is defined and disposed between the protruding flanges (42) and that is adapted for a cord (22) of the window blind (2) to wind thereon. The cord-blocking unit (5) is mounted on the wheel holder (3), and has a blocking surface (511) that faces and is disposed proximate to the wheel surface (43) of the guiding wheel (4) for preventing the cord (22) from slipping off the wheel surface (43) and out from the protruding flanges (42).

The present invention relates to a very flexible Venetian blind that easily can be adapted to various sizes of for instance window openings, by a person having limited skill in mounting and adapting Venetian blinds. Also the Venetian blind according to the invention is designed such that individual slats can easily be removed for instance to change the overall size of the Venetian blind or for repair or replacement of individual slats. It is hence also easy according to the invention to change the overall appearance, for instance colour, of the Venetian blinds to meet changing requirements. These and other objects and advantages are attained by the Venetian blind according to the invention. It is understood that although the various elements of the Venetian blind according to the invention here are described and shown as used to form one specific Venetian blind it is also possible to use one or more of the elements (for instance the bottom portions, the lift mechanism etc.) separately, for instance in connection with other devices.

The present invention relates to a lift mechanism for a Venetian blind of the type that comprises pairs of lift cords (5) for raising or lowering the slats (7) of the Venetian blind. The lift mechanism according to the invention comprises two cone or drum portions (2, 3), upon an outer circumferential surface of one (2) of these portions one lift cord of a given pair of lift cords is wound upon rotation in one direction of the drum portion (2) and from which the lift cord is unwound upon rotation in the opposite direction of the drum portion (2) and upon an outer circumferential surface of the other (3) cone or drum portion the other lift cord of a given pair of lift cords is wound upon rotation in one direction of this other drum portion (3) and from which the lift cord is unwound upon rotation in the opposite direction of this drum portion (3).

A device for winding a suspension cord (110) of a blind is provided to wind a suspension cord (110) disposed on a blind. The suspension cord (110) is spirally wound about a cord spool (300) through a spiral groove (333) of a guide component (330), and then arranged along the cord spool (300) in sequence. Additionally, when the cord spool (300) is connected to a power resilient element (700) as a power source of rotation, friction force is applied to the cord spool (300) through an adjusting component (500) to adjust the output torque of the cord spool (300), such that the torque applied to the cord spool (300) by the power resilient element (700) can be balanced out with the torque applied to the cord spool (300) by the gravity of the blind.

The invention relates to a blind-manoeuvring device (40) consisting of a drum (42) for winding at least one cord (2, 5) which is connected to the blind and a support (41) for said drum (42). The aforementioned drum support comprises at least two parts (41a, 41b) which are assembled such as to form passage holes (48) in which the cords (2, 5) can slide. The invention is characterised in that each of the aforementioned parts (41a, 41b) supports the drum (42) directly or indirectly. During assembly, one such device facilitates the introduction of cords into the winding drum support and enables said task to be automated.
