Fire And/Or Smoke Blocking Device

摘要

An assembly for covering an opening in a structure. The assembly has a roller to be mounted to a portion of the structure defining a portion of the structure opening and a member disposed on the roller assembly. The member is operable between a retracted position where it is wound onto the roller assembly and an extended position where it is unwound from the roller assembly. The member includes first and second portions with mutually opposing edges in a closed position. A fastener releasably attaches the first and second panel portions to each other. The first and second panel portions are separable in response to an egress force to form an egress through the member.

主权项

1. An assembly for covering a structure opening in a structure wall, the assembly comprising:
a retracting member configured to be mounted to a portion of the structure defining the structure opening; a curtain panel connected to the retracting member and being movable between a retracted position where the structure opening is at least partially uncovered and an extended position where the curtain panel covers the structure opening, the curtain panel comprising:
a first panel portion having a first vertical edge portion and a first extended position in which the first vertical edge portion is substantially fixed when the curtain panel is in the extended position;a second panel portion having a second vertical edge and a second extended position when the curtain panel is in the extended position, the first and second vertical edge portions being mutually opposing when the first and second panel portion are in the first and second extended positions, the edge portion of the second panel being moveable with respect to the first portion; a resealable fastener arranged along a length of the opposing first and second vertical edge portions of the first and second panel portions and configured to releasably attach the first panel portion and the second panel portion to each other along said length, wherein: the fastener is configured to at least partially release the first and second panel portions from each other along said length and a portion of the second panel portion is movable from the second extended position to a third position folded away from at least part of the first vertical edge in response to an egress force exerted on the second panel portion proximate said length to form an egress through the fire door assembly, and upon relaxation or removal of the egress force, the second panel portion returns from the third folded away position to the second extended position, and the fastener causes the first and second panel portions to reattach to each other along said length, to prevent fire and/or smoke from passing through the curtain panel.
