JPH0341973A - Emergency air supply assembly for shut-up fireman - Google Patents

Abstract

PURPOSE: To supply respiration air for an emergency rescue as quick as possible by shifting from the water supply to the supply of respiration air for an emergency rescue to personnel confined in a burning toxic-gas-filled building and used up the air from their portable respiration source normally being carried around, and by shifting the standard fire extinguishing hoses to such, as easily and quickly as possible. CONSTITUTION: The respiration air supply assembly for an emergency rescue 21 is uniquely designed so that the respiration air is continuously supplied into the fire extinguishing hoses 18 from the air supply tanks 39, 40 and that the check valves 31, 32 are positioned/installed between the entrance of a T-joint 29 and the tank air supply hoses 35, 26 each connected to the air supply tanks 39, 40. For use, the shut valve 43 is opened on the top of the tank 39 to draw the air from the tank into the hose 35, which then passes through the check valve 31 to enter into the hose 28, thus, flowing down into the adjuster 24. There, the air passes through a quick coupler assembly 20 connected to the air for an emergency rescue to enter into the fire extinguishing hose 18, thus, supplying the respiration air for an emergency rescue of personnel confined inside.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention provides a fire hose for firefighters and/or rescue personnel trapped in a burning building or a building filled with explosive and/or toxic gases. An emergency air supply assembly for a firefighter, the assembly being adapted to supply emergency breathing air through a firefighter.

BACKGROUND OF THE INVENTION This emergency air supply assembly is provided in conjunction with a fire hose to quickly connect an emergency air supply unit to the inlet end of the fire hose to assist trapped firefighters and/or rescue personnel. Equipped with emergency air snap cover means for supplying emergency breathing air to personnel. If a firefighter becomes trapped during such an emergency, the air in the portable air supply unit that firefighters usually carry will be exhausted, and unless the firefighter can be rescued quickly, they will suffocate to death. Will. The present invention provides immediate access to rescue air to a trapped firefighter by easily and quickly converting a fire hose normally used by firefighters to provide water to use to provide rescue air. can be supplied to

In such emergency operations, the water supply to the fire hose is shut off and the emergency air supply assembly is snapped onto the nozzle end of the fire hose. A trapped firefighter should place the artificial end of the fire hose in an emergency air collection member, such as a bag, shoe, or clothing item, which will contain the emergency air for use by the firefighter. A breathing mask tube, which is normally connected to a (depleted) portable air supply unit carried by the firefighter, is then inserted into the emergency air collection member to supply emergency air to the firefighter. If several firefighters out of the entire crew are trapped,
Firefighters can simultaneously receive emergency breathing air from the emergency air collection member by inserting their breathing mask tubes into the emergency air collection member, thereby sustaining their lives until rescue.

When trapped firefighters and/or rescue personnel are in a cubicle, tent, waterproof cover, or any other type of closed space that serves as an emergency air collection member, provide emergency air to them as described above. It is within the scope of the present invention to be able to provide

Another embodiment of the invention selects an inlet end closure cap having an air connector snap-engaging member passed therethrough for connection to an independent emergency air supply assembly such as an air tank bank or an air compressor. A fire hose is provided for emergency use. Furthermore, this embodiment of the closure cap according to the invention comprises:
Use this fire hose to provide emergency air to a person trapped underwater in a sunken boat or vehicle that has fallen into a water crevice or accidentally fallen into a river, lake, or filled channel. Can be used independently. The emergency air supply is snap connected to an air connector located on a closure cap located at the artificial end of the fire hose. The fire hose is then lowered into the trapped vehicle or boat below the water and the nozzle end is placed in the area where the person is trapped to provide emergency breathing air to the trapped person.

The fire hose can thus be used independently of the fire engine, and this fire engine can therefore continue to be used to supply water to other fire locations through another fire hose.
