DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet for ensuring the safety of a firefighter, police, rescue squad, self-defense force, etc. at night or in a dark place by allowing a third party to visually recognize the activity.

[0002]

2. Description of the Related Art A helmet worn by a firefighter or the like during their activities is designed to protect the head from fire or impact. There are also helmets equipped with lighting lamps to facilitate activities at night.

[0003]

By the way, when a firefighter performs a firefighting operation at a fire site and a rescue squad conducts a rescue operation, a power failure occurs first at night and smoke is trapped. In many cases, firefighters and rescue teams are not aware of the appearance of firefighters or firefighters working in the scene of a fire. For this reason, firefighters, rescue squads and victims who are active may be accidentally flooded with fire hoses, and the extremely high water pressure may cause injuries or falling accidents.

[0004] It is an object of the present invention to provide a helmet in which firefighters and members of a firefighter or a member of the firefighter during firefighting or rescue operations at night or in a dark place can be easily recognized.

[0005]

The configuration of the present invention is as follows. Power supply, light emitter, day / night identification sensor, helmet
Human body detection sensor and the day and night identification sensor for detecting the wear of the outputs a signal by detecting a predetermined brightness, and the person <br/> body detection sensor outputs a signal by detecting a helmet A helmet provided with a control circuit for receiving the input of these two signals and closing the circuit between the power supply and the illuminant only when the illuminator emits light.

[0006]

When a firefighter or a rescue worker wears a helmet during an activity, the human body detection sensor detects this and outputs a signal, and a signal is output when the day / night identification sensor detects a certain brightness (darkness). The control circuit turns on the power only when the signal is output from both of them to cause the light-emitting body to emit light, and turns off the power when the output of the signal from one or both is lost.

[0007]

In the drawings, reference numeral 1 denotes a helmet, 2 denotes a luminous body (for example, EL, LE)
D, etc.), 3 is a power supply, and this power supply can use a dry cell, a solar cell, or the like. Reference numeral 4 denotes a day / night identification sensor, which outputs a signal when a certain lightness (darkness) is detected.
Reference numeral 5 denotes a human body detection sensor, which is an infrared sensor that detects a wearer's head with infrared rays and outputs a signal when the helmet 1 is worn. This sensor is, for example, a mechanical switch mechanism. The structure which detects wearing may be sufficient.

Reference numeral 6 denotes a control circuit which turns on the circuit between the power source 3 and the light emitting element 2 only when a signal is output from the day / night identification sensor 4 and a signal is output from the human body detecting sensor 5 at the same time. This is a function of causing the body 2 to emit light and turning off the power supply 3 when the signal from one or both of them disappears to stop or stop the light emission of the light emitting body 2. 7 is a waterproof cover.

The helmet 1 is provided with other smoke or harmful gas detection sensors, high temperature detection sensors, and the like, and an alarm device operated by these sensors is attached to the helmet, so that the active firefighter A measure may be taken so that rescue workers sense danger and can quickly evacuate to a safe place.

[0010]

The present invention is configured as described above and has the following effects. a. The firefighters and rescue workers wearing the helmet and the checking device according to the present invention can easily understand the activity state even in darkness, and it is safe that water is not accidentally discharged to these members during firefighting activities. b. Even if members fall down at the scene of a fire, they can be found immediately. c. It is safe because danger can be predicted with an alarm before poisoning due to harmful gas occurs. d. The day / night identification sensor and the human body detection sensor automatically determine the darkness or the presence or absence of wearing, and output this as a signal, so there is no need to operate each time, and there is no worry that it will not operate due to forgetting to operate and it is safe. is there.
