Breakout mechanism for revolving doors

Breakout mechanism can be applied to both 3 or 4-leaf automatic or manual revolving doors and makes the revolving door leaves book-fold when an adjustable amount of force is applied. This enables rapid evacuation of the building in case of an emergency and makes passage of large objects possible which normally cannot pass through the revolving door. This feature is preferred mostly in shopping malls, hospitals, hotels, public buildings and commercial buildings.
