{Holder of fire extinguisher hoses}

The present invention relates to a fire extinguisher hose fixing device which is mounted on a hose of a fire extinguisher and fixes the hose in a proper direction and angle so that a disabled person can operate the fire extinguisher with one hand.

Currently, each government office and public institution has a fire extinguisher. However, the fire extinguisher has many limitations for the disabled to use only one hand.

Fire extinguishers are devices that can be used to turn off and carry out fire by using the effects of cooling or air shutoff of the fire extinguisher in the early stages of fire. 1, a general fire extinguisher has a lever 40 on a fire extinguishing agent container 30, a hose 50 connected to one side of the lever, and a trumpet 60 mounted on an end of the hose 50 .

Generally, when using a fire extinguisher, hold the lever 40 with one hand and hold the hose 50 to the fire point with the other hand, so that the fire extinguishing agent is ejected from the trumpet 60. Therefore, it is impossible to operate the fire extinguisher with only one hand.

Therefore, it is very difficult to cope when a person with a disability is in a fire situation. In addition to not protecting the person with a disability from the fire, it can not help anybody who needs to rescue someone in a fire situation.

For example, when a hemiplegic patient with a stroke or spinal cord injury finds a fire scene, conventional fire extinguishers are not suitable for these patients to actively extinguish the fire. In addition, these patients do not evacuate quickly because of the lack of exercising function of the lower limb, even after the evacuation of the fire. Because of this, it is often seen in the article that a fire accident that leads to lung injury and death due to toxic gas inhalation in the event of a fire.

In order to compensate for the disadvantages of such general fire extinguishers and to operate the fire extinguisher with one hand, there is a need for a one-hand extinguisher hose fastening device that fixes the angle and direction of the hose. This allows the handicapped person, who can only use one hand, be able to point the hose of the fire extinguisher accurately to the point of fire with one hand.

The fire extinguisher hose fixture 70 of the Korean Registered Utility Model No. 20-0226873 is used for fixing the hose when not in use. As in the present invention, a means for holding and fixing the direction of the hose constantly no.

Japanese Laid-Open Patent Application No. 2013-202169 discloses that the fire extinguisher hose is formed in the shape of a letter, and it is configured to rotate back and forth along the horizontal axis so that a fire extinguisher can be used with one hand. However, this is not a means for fixing only a fire extinguisher hose in a conventional fire extinguisher, and a fire extinguisher of the present invention must be purchased in order to use it.
