A rollo assembly comprises a rollo screen (6) for cooperation with an opening (2,3), said rollo screen having opposed forward (7) and rearward edges extending in a transversal direction and two opposed side edges (8) extending in a longitudinal direction, a biased winding shaft (9) which is rotatable for winding on or winding off the rollo screen at the rearward edge thereof, an operating beam (10) connected to the forward edge (7) of the rollo screen (6) and defining two opposite operating beam ends (11), and two guide members (12) extending in said longitudinal direction and each defining a guide channel (17) for guiding a respective one of the operating beam ends (11). Near to each of the operating beam ends (11) a first end (14') of an elongate flexible drive member (14) is connected, wherein each drive member, starting from the position near to the respective operating beam end (11), firstly extends in the longitudinal direction away from the winding shaft (9), next around a reversal member (13) and finally in the longitudinal direction towards the winding shaft (9), wherein each drive member (14) has a second end (14") which has a stationary position. The reversal member (13) is driven for a translation in said longitudinal direction. |
