A screening device (1) for use in banks or building societies is provided where a flexible screen (7) can be moved across a window (5) which is located above a counter (4) to obscure the view through the window (5) and thereby break visual contact between the cashier on one side of the window (5) and a gunman on the other side of the window (5). The movement of the flexible screen is rapid and is triggered by the provision of an electrical alarm signal. The leading edge of the screen (7) is provided with a rail (11), itself having a leading edge covered with a strip of padding (13) to prevent injury to a cashier's hand if positioned below the rail (11). The rail (11) is made heavy so that it descends under the force of gravity. The screen is dispensed from a first roller (9) which is biased to wind the screen (7) onto itself but the biasing force of the roller (9) is less than the force exerted on the rail (11) by gravity so that on activation of a release mechanism the rail (11) and screen (7) descend rapidly down across the window. |
