Abstract: An emergency breathing and warning system (100) is disclosed to provide an emergency means of obtaining fresh air for individuals trapped within a building containing noxious fumes or smoke. The emergency breathing and warning system (100) includes flanged conduit (122) which passes through an exterior partition (125) or other structural element to provide access to fresh air external to the building. System (100) includes a first breathing apparatus (104) having a breathing mask (112) coupled to a breathing tube (106). Breathing tube (106) passes through conduit (122) to access the fresh air external to the building. First breathing apparatus (104) includes filter element (108) and coupling (110). Coupling (110) provides a means for providing fresh air to a second breathing apparatus (114) having breathing mask (118) and second breathing tube (116) which is frictionally engaged with coupling (110). Coupling (110) further includes sealing cap (140) for sealing coupling (110) when second breathing apparatus (114) is not in use. Warning device (102) is coupled to breathing tube (106) to provide an external visual indication that the emergency breathing and warning system (100) is in use. Warning device (102) is coupled to first breathing tube (106) by coupling wire (103) to provide a positive deployment and subsequent retraction through conduit (122) by breathing tube (106). A storage container (120) is also provided for maintaining the individual elements of emergency breathing and warning system (100) when system (100) is not in use.

Show all 13 claims
What is claimed is:     1. An emergency breathing and warning device for use by at least one person from within a building, comprising:
  • (a) conduit means for establishing access to a source of fresh air external said building, said conduit means including a hollow tube having a first end and a second end extending through an outside wall of said building, said first and second ends being located internal and external said outer wall respectively, said hollow tube being formed of a metallic composition having an internal diameter approximately 0.75 inches, said conduit means further including a plug releasably coupled to said first end of said hollow tube;
  • (b) respiration means passing through said conduit means for coupling said fresh air source to said person, said respiration means including said warning device, said warning device being adapted to reversibly pass through said conduit means for deployment external said building, said respiration means including a first breathing tube having an outside diameter less than said inside diameter of said hollow tube, said first breathing tube having a first end for passage through said hollow tube to access said fresh air source, said warning device being coupled to said first end of said first breathing tube, said warning device being retracted from said deployment coincident with removal of said first breathing tube; and,
  • (c) storage means for maintaining said respiration means convenient to said person or said conduit means when said respiration means is not in use.
