Abstract

The invention relates to an emergency release device for a building closure operator for decoupling a motorized building closure from a motor operator assembly under emergency conditions. To diminish the risk of injury by free-fall of a decoupled building closure wing by a simple and cost-effective design the invention proposes providing a safety or securing unit which safeguards or secures the emergency release device against unintentional or unauthorized actuation.
