Abstract (en)
[origin: US4458929A] The subject of the invention is an automatic locking mechanism for a revolving shutter to protect the latter against unauthorized pulling up from the outside, using a locking device which is moved into the locking position after the revolving-shutter casing has been lowered. The device has a lateral axle bearing, with a round bearing element (11) for a belt pulley (2) and a fixed square bearing pin (8) connected thereto and the end of which is designed as a round cylinder. The belt pulley (2) has an annular web (2a) and the roller insertion cap (1) has an annular web (1a), the side webs (1a/2a) having different diameters and interlocking coaxially. A pivotable locking lever (6) engages positively through coinciding gaps. In the lowered state of the revolving-shutter casing, the lever (6) engages with the fixed bearing pin (8) and clamps belt pulley and roller insertion cap against unauthorized turning, so that the revolving-shutter roller connected to the roller insertion cap is also locked.
