Shield system with funnel-shaped membrane

摘要

The system (26) has three flexible bars (36) with respective upper and lower ends, where the lower end of one bar is anchored at a bottom or in a holder (38). A set of slots (34) is connected with an umbrella partition (28). A traction mechanism downwardly pulls a lower end of the partition and pushes the upper ends of the bars arranged in the slots against a support such that the bars are bent in a preset form by forms of the slots and the partition is fixed. The slots are connected with the partition along radial outer or inner edges of the slots.
