Barrier opening system for emergency escape and rescue

Abstract

A barrier opening system for emergency escape and rescue comprises a vertical acting barrier device, an escape device, and a rescue device, the vertical acting barrier device winds a barrier via a winding shaft; a prestressed spring preloaded on the winding shaft for storing a restoring force when the barrier is unwound by the winding shaft; a brake mechanism for stopping the winding shaft from rotating; a brake release mechanism for releasing the winding shaft under an abnormal condition; an escape device comprising an identification unit and a master key for activating the brake release mechanism; the identification unit identifies a rescue personnel's identity before allowing the personnel to use the master key to activate the brake release mechanism; when the emergency button and / or the master key activate(s) the brake release mechanism to release the winding shaft, the barrier can be lifted up by the restoring force.

Description

BACKGROUND OF THE INVENITON[0001]Field of the Invention[0002]The present invention relates to a barrier opening system for emergency escape and rescue, through which a barrier can be opened immediately by a prestress / restoring force in the shortest possible time without having to break through the barrier in case of emergency.[0003]Description of the Related Art[0004]For access control barriers such as fire-proof barriers, smoke-proof barriers, and emergency exits, a vertical acting barrier is widely used. Current Building / Fire Law has strict regulations for the exits and entrances of a public space where many people gather, especially for stores and multi-family residence that have no escape barrier but only one exit and entrance, and for the safety standards of compartment barriers and / or emergency exits. In case of emergency or imminent danger, a vertical acting barrier must be opened as quickly as possible, even without electricity and external assistances, to prevent the barrie...

AI Technical Summary

Benefits of technology

The present invention is a barrier opening system that allows emergency escape, rescue, and vehicle relocation without having to break through the barrier. It uses a handheld identification device to access the system and obtain the user's permission to open the barrier. This system allows authorized personnel to enter a building or relocation without damaging property or affecting rescue time, providing a safe and efficient means of escape in emergency situations. Even people trapped indoors can open the barrier quickly by pressing the emergency button in the shortest time for safe escape.

Problems solved by technology

Such manual mode operation would be difficult to the elderly, disabled, pregnant women, and children, and would cause a delay in evacuation.

Furthermore, from the rescue aspect, police officers / firefighters can not enter the building without a key for such conventional vertically acting barrier if an emergency occurs indoors, and they have to break through the vertical acting barrier by force.

Not only is the property damaged, but also a delay in rescue results.

As such, police officers / firefighters can have access to a master key from the storage box, and enter the building for fire rescue without having to break through the barrier, which will cause damage to the property, and result in a fire rescue delay.
