In order further to develop a security device for a roller shutter or rolling shutter door which is made from slats and can be wound up onto a shaft and unwound therefrom, in particular if the last slat of said shutter or door is provided with at least one laterally extensible securing bolt, such that tampering can be eliminated, the intention being for this to be achieved in a simple manner with cost-effective means and for the security device to be fitted on the roller shutter in a simple manner, it is proposed that the shaft (7) has a locking mechanism formed by a cam plate (21), arranged on at least one side of the shaft (7), and a laterally projecting safety finger (22) which interacts with said cam plate and is provided on the uppermost slat (2.1) close to the shaft, and by a locking lug (23) which is fixed to the framework and engages beneath the safety finger (22) when the roller shutter is closed, the cam plate (21) exhibiting a clearance (21.2) extending to the circumference of the shaft (7), and the uppermost slat (2.1) of the roller shutter (1) being fastened on the shaft (7) such that, when the roller shutter (1) is drawn up, the safety finger (22) is guided into the clearance (21.2) of the cam plate (21) and held there. <IMAGE> |
