Device for controlling the closing sequence of a two-leaf revolving door system

摘要

The invention relates to a device for regulating the closing sequence of a two-leaf revolving door system, which has an overhanging active leaf and an undercut passive leaf. The active leaf and the inactive leaf are each operatively connected to an output shaft of a drive device. Furthermore, a blocking device is provided, by means of which the active leaf can be blocked or released, depending on the position of the passive leaf, by having a coupling point for a mechanical transmission element. The blocking device acts on a movable component of the drive device of the active leaf by having a brake drum coupled to the movable component via a freewheel bearing. The blocking device has two brake shoes, which are acted upon by at least one of the two brake shoes supporting the tension spring against each other on the brake drum.
