BARRIER SYSTEMS AND ASSOCIATED METHODS, INCLUDING VAPOR AND/OR FIRE BARRIER SYSTEMS
First Claim
1. A barrier system, comprising:
- a barrier having a first end and a second end, the barrier being movable between a deployed position and a retracted position;
a spool coupled to the first end of the barrier, the barrier being positioned to be wound onto and off of the spool as the barrier moves between the deployed and the retracted position;
a housing positioned to contain the spool and at least a portion of the barrier, the housing having an opening through which the barrier passes as the barrier moves between the deployed and the retracted position; and
a seal member in the housing and sealably engaging a portion of the barrier adjacent to the spool, the seal member being configured to prevent migration of fluid through the housing.

Abstract
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 seal assembly positioned in a housing and contacting the spool to create a barrier to smoke and vapor migration through the housing. The system still further includes a sensor operably coupled to a control system and positioned to sense barrier position as the barrier moves between the deployed and the retracted positions.

9. A barrier system, comprising:
-
a barrier having a first end and a second end, the barrier being movable between a deployed position and a retracted position; a spool coupled to the first end of the barrier, the barrier being positioned to be wound onto and off of the spool as the barrier moves between the deployed and the retracted position; a housing positioned to contain the spool and at least a portion of the barrier, the housing having an opening through which the barrier passes as the barrier moves between the deployed and the retracted position; a first seal member positioned to sealably contact a first portion of the barrier within the housing adjacent to the spool; and a second seal member positioned to contact a second portion of the barrier, the first and second seal members being configured to resist migration of fluid through the housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A barrier system, comprising:
-
a gas impermeable barrier movable between a deployed position and a retracted position; a spool coupled to the barrier, the barrier being positioned to be wound onto and off of the spool as the barrier moves between the deployed and the retracted position; a resilient seal member comprising a base structure and an engagement portion projecting from the base structure in a direction generally tangential to a portion of the barrier on the spool, the engagement portion sealably contacting the spool to form a resilient barrier between a first side of the resilient seal member and a second side of the resilient seal member, wherein the engagement portion is shaped such that a pressure differential between the first and second sides of the resilient seal member urges the arm and barrier into engagement with each other to increase resistance to fluid migration. - View Dependent Claims (18, 19, 20)

21. A barrier system for use adjacent to a structure having an opening therein, the system comprising:
-
a barrier having a first end and a second end, the barrier being movable between a deployed position and a retracted position, a portion of the barrier moving through opening as the barrier moves between the deployed and retracted positions; a spool coupled to the first end of the barrier, the barrier being positioned to be wound onto and off of the spool as the barrier moves between the deployed and the retracted position; a drive device configured to drive the barrier between the deployed and retracted positions; and seal members adjacent to the barrier and sealably engaging opposing sides of the barrier generally adjacent to the opening and configured to prevent migration of fluid from a first side of the barrier over the spool to a second side of the barrier opposite the first side of the barrier. - View Dependent Claims (22, 23, 24)
