The chain wheel (14) engages the chain (5) and is set between the arms (11-16) a U-shaped holder. Its rotation is transmitted via a pin (15) extending into a bushing casing. The intermediary space between the arms and the chain wheel is covered by a casing (20). For fitment between the panels of a double-glazed window, the chain wheel is located in a separate housing, and activates the bushing via an extended, pliable pin which can be drawn up an angle through a hole in the window frame. The blind can also be fitted in a cassette both free-hanging and between window panes. |
