Abrégé

The present disclosure relates to a barrier system for shielding humans from harmful exposure to fire, smoke, noxious fumes, or contaminated air. Some embodiments provide a deployable barrier system that has a barrier retract assist system configured to assist a user in manually moving the barrier from the deployed position toward the retracted position with at least a portion of the barrier being rolled onto the barrel portion for egress past the barrier. The retract assist system can be positioned inside of the barrel portion.

Abrégé

A barrier assembly comprising a horizontally deployable vapor barrier assembly with a frame with opposing side guides extending between a header and footer. A guide rod contained in each side guide extends between the header and the footer. A vapor barrier is deployable horizontally with side edge sleeve portions that slide axially over the guide rods. At least one roller is connected to each of the side guides adjacent to the guide rod, and each roller supports a portion of the vapor barrier's side edge portions. The rollers rolls on the edge portions as the sleeve portion slides axially over the guide rods as the vapor barrier moves between the deployed and stowed positions. Lifter plates are attached to each of the side guides and positioned to engage support carriages and temporarily lift the support member out of engagement with the support surface over segment joints as the vapor barrier moves between the stowed and deployed positions. A drive system moves the vapor barrier between the stowed and deployed positions.

Barrier systems and associated methods, including vapor and/or fire barrier systems, are disclosed herein. One aspect of the invention is directed toward a barrier system that includes a barrier coupled to a spool. The barrier is positioned to be wound onto and off of the spool as the barrier moves between a deployed position and a retracted position by a drive assembly. The system further includes a control system coupled to the drive assembly and configured to command operation of the drive assembly. The system still further includes a sensor operably coupled to the control system and positioned to sense barrier position as the barrier moves between the deployed and the retracted positions.

Abrégé

The subject invention comprises a flexible multilayer fire-rated material that has at least one layer of an intumescent material. Because it is flexible, the fire- rated material is usable in situations where it is desirable for the fire-rated material to be rolled up or folded into a non-flat storage application. This allows the subject fire- rated material to be used in fire-rated and smoke-resistant barriers that are recessed in walls or ceilings until use. One end use embodiment includes without limitation, recessed or rolled up fabrics used in elevator lobby ceilings to seal off elevators or their lobbies from smoke or fire.
