  At construction sites, underground objects such as water pipes, gas pipes, and electric wires, or fictional objects such as optical cables, communication lines, and high-voltage electric wires are stretched around. In such an environment, there are many operations that are carefully performed such as heavy machinery excavation and crane work. If they come into contact with the pipes and lines, the lives of neighboring residents, as well as the disruption of urban functions, and the risk of losing the lives of workers who have committed negligence and nearby workers are increasing.

  In order to prevent the above accidents and disasters, Patent Document 1 discloses a safety meeting in which precautions are given to heavy equipment operators and workers prior to work, and a device that calls out precautions for danger at regular intervals. And 2.

JP-A-11-139206 Japanese Patent Laying-Open No. 2005-158041

  The one disclosed in Patent Document 1 calls the above-mentioned precautions recorded at regular intervals to a worker who is continuously working alone, but the power supply means is a car or the like. The work range will be specified.

  Moreover, since what is shown in Patent Document 2 is required to record the above-mentioned precautions using a personal computer, it is not suitable for work sites without a personal computer or workers who cannot use it.

  When working alone or away from other workers above all else, in the unlikely event that something happens to you, especially in situations where you can not speak loudly due to pain etc., you may seek help from other workers or nearby people It cannot be done and the damage will be expanded.

  Since the present invention is a human being no matter what device is used, accidents and disasters caused by human errors that can hardly be lost can be easily used by anyone regardless of work, age or gender. Of course, the purpose is to minimize accidents and disasters that have occurred.

  In order to achieve the above-mentioned object, the present invention has, as a first solution, a control unit that is detachably attached to the outside of a helmet. This unit is provided with an emergency button and an emergency buzzer. An emergency can be made to surround by a buzzer simply by pressing. In addition, the flash lamp is turned on from the top of the helmet at the same time as pressing the emergency button, so that an emergency situation can be caused by sound and light.

Also, as a second solution, when recording the cautions, it is structured to record the cautions with the voice while pressing the button. In order to be able to recognize the matter, the flash lamp is turned on simultaneously with the recording and playback of the cautions at the tip of the helmet that is easy to enter visually. It is structured so that it can be used anywhere.

  As described above, the helmet of the present invention can be confirmed from the hearing and the visual perception at any set time in any place with a simple operation, and can prevent accidents in advance. In the event of an emergency, it is possible to notify other workers and those around by sound and light quickly and easily, so that damage can be minimized.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIGS. 1 to 5, 12 is a power on / off button, 13 is a device use confirmation lamp, 14 is a button to be pressed at the time of real voice recording, 15 is a button for confirming and reproducing the recorded content, and 17 is a real voice recording / playback interval. A dial for setting time, 18 is a microphone for recording notes, and 19 is a speaker for reproducing real voice recording.

  16 is a button to be pressed in an emergency, 20 is a buzzer speaker that sounds at the same time as the button is pressed in an emergency, 11 is a box containing a dry battery as a power source of the apparatus body, and 21 is a light emitting for replaying notes A flash lamp 22 is a flash lamp that emits light simultaneously with an emergency buzzer, 1 is a helmet body, and 2 is a collar of the helmet.

  Reference numeral 24 denotes a bracket for attaching the apparatus main body to the helmet.

Hereinafter, the procedure for using the helmet will be described with reference to FIG.
A) Attach the device body to the side groove of the helmet using the mounting bracket as shown in Fig.2.
B) Fix the flash lamp that emits light at the same time as playing the recorded content to the helmet collar as shown in Figs.
C) Fasten the flash lamp that lights simultaneously with the emergency button to the top of the helmet.
D) Press the power button 12 and confirm that the use confirmation lamp 13 of the apparatus body is lit.

G) The timer setting dial 17 is used to arbitrarily set the real voice recording / playback interval, 6 seconds to 60 minutes.

  This completes the setting of the accident prevention device function. When the recording and playback interval time set in G) is reached, the recorded notes are played back, and at the same time, the flash lamp attached to the helmet collar emits light.

Next, a method of using the emergency notification device function that minimizes an emergency situation that has occurred should be described.
H) Press the emergency push button 16.
I) A buzzer is emitted from the speaker 20 at the same time as the above button is pressed, and the flash lamp 22 emits light to notify the surroundings that an emergency has occurred with sound and light.

  Next, the effects of the invention of one embodiment of the present helmet will be described using examples.

  At the construction site, after the work content meeting before starting work, discuss the danger points and precautions of each work with the on-site manager, managers, and workers, sing the danger points, and start each work. . Below are some examples.

  Today's work is the content of repair work in the manhole. The manhole yard is small, so one person can enter it, and on the ground, there are two people, one for material delivery and one liaison worker. .

  When meeting the danger point before the start of work, the weather is forecast to be downhill, so the workers entering the plant should use the device to check the increase in the amount of water flowing at their feet. When it was confirmed that the voice was recorded and the risk was high, the playback interval time was set to 3 minutes. In addition, he told the ground workers that he would like to confirm himself because he would press the emergency button when an emergency occurred.

  The ground worker makes today's safety point the safety confirmation of the worker working in the manhole yard, makes a real voice recording of “Check the sky with Mr. ○○”, and rushes to the surrounding workers when an emergency buzzer sounds I told you that I wanted to.

  I started work with the above contents. During the work, the recorded content is played back at every set time and the flash lamps can be used to reconfirm the precautions, and the amount of water due to rain can be checked regularly by checking the water increase at the footsteps and the weather conditions each time. I noticed that it was increasing little by little, and I could judge that further work was dangerous, and I decided to cancel the work, but when the worker got out of the manhole, the ground worker did not notice that he slipped and fell from the ladder It was. The fallen worker fell into a situation where he could not make a loud voice, so he pressed the emergency button on the device and sounded a buzzer. When the ground worker noticed the sound and looked into the manhole, the flash lamp that was lit at the same time as the emergency button was lit in the dark manhole, so the position of the worker who fell could be confirmed and rescued quickly. I was able to.

  If you weren't using a helmet-type emergency support and accident prevention device, you might have become crazy about work, slowed down to notice changes in the amount of water at your feet, and was a serious accident. In addition, the worker who fell down might not have noticed, and it might have been a tragic accident as time passed and the water began to rise.

  Another example is excavation work using a power shovel, and when an operator riding a heavy machine confirms the work location, there are communication cables and power transmission lines such as optical cables within the work radius. There was a real voice recording. Although the work was progressing smoothly, there was a notice from the site manager and the pace that did not reach the planned drilling volume today, and the operator began to work quickly to catch up. At this time, I started to forget that there was an electric wire in the sky, and it was becoming full in my head due to the amount of excavation. I was able to reconfirm that there was a calm work, but it did not reach the planned drilling amount.

  When new elements come into your head as described above, you gradually forget what you have been careful about, and you have been careful and safe until now. Accidents of cutting with heavy machinery. In recent years, the Internet and the like of electric wires and communication lines are prosperous. If they are cut off, damages and the like are immeasurable and will greatly affect future construction order receiving activities. Just thinking about it makes me scared.

  The two examples above are really serious disasters if a disaster occurs. A human error causes things that can't be done with "... if you do ...".
