SCREENING DEVICE WITH MOTOR USE AND USE HEREOF

摘要

Screening device is proposed for screening opening in building, window, door or the like, said screening device comprising a screening element (11) which in an inactive position is rolled up, folded together, gathered together or the like at a first position. The screening element is connected at a free end to a movable part such as a bottom bar (10). This bottom bar can be moved in relation to said first position by means of one or more endless driving cords or the like which extend in one or more closed circuits and which can be driven by means of least one driving motor. The movable part (10) is mechanically connected to said at least one driving cord by means of friction-producing means which are of such a kind that the friction can be overcome by a manual operation.
