Title:
SCREEN SYSTEM FOR FIREPROOF ZONE TO EASILY PASS PERSON
Document Type and Number:
Japanese Patent JP3146979
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily and inexpensively execute fire prevention while using a heat resistant and flexible screen made of cloth, to reduce a space for installation, to provide remarkably high fireproof and smoke-proof performance by effectively shielding opening parts inside a building, and further, to let a person easily pass through a screen plane while partitioning it.
SOLUTION: A screen 1 is composed of a main body part 1b formed with an opening part 1a for refuge passage in the lower end at the prescribed position and a door part 1c whose upper part is integrally bonded with the main body part while being arranged so as to close the opening part. A sub weight bar 6 at the lower end of the door part is dynamically loosely restricted to a main weight bar 5 at the lower end of the main body part by suitable coupling means (wires 7 and coil springs 8), remarkably displaced in respect to the main weight bar while receiving external force applied in the case the person tries to pass, and recovered to an ordinary position parallel in contact with the main weight bar by restricting force when there is no external force.
