Description

  The present invention relates to a work cap that is equipped with a warning device that emits an alarm such as sound or vibration when a light and breathable work cap approaches a high-voltage charging unit.

Conventional protective hats (helmets) are made of reinforced plastic or metal and are mainly intended to protect the head from impact forces.
For this reason, when the ambient temperature is high as in the summer, the protective cap for work lacks air permeability, so that the operator has to continue working with resistance to weight and heat. This is because the working protective cap was made of reinforced plastic or metal.

On the other hand, when working close to equipment, power transmission lines, etc. that are charged with a voltage of 600V to 7,000V or more, such as construction sites, in order to prevent electric shock accidents, do not enter the dangerous distance. It was necessary to arrange and monitor three observers.
However, when the worker is immersed in the work, there is a risk that he / she may perform an unsafe act without noticing the alert of the supervisor.

In order to prevent this, an operator often enters a work site by attaching or wearing a voltage detector that alerts the user to the protective hat (helmet).
However, this method is insufficient as a countermeasure against human error such as forgetting to attach the voltage detector or forgetting to wear it.

Examples made in view of these points include Japanese Patent Application Laid-Open Nos. 11-12842 and 5-14932.
This is a protective cap (helmet) with a voltage detector attached to it, so the human error can be prevented, but no consideration is given to the heat and weight of the worker, so the ambient temperature is high. Not suitable for summer.
For this reason, there was an accident that the worker entered the work site while wearing a safety hat.
JP-A-11-12842 JP-A-5-14932

If a protective cap (helmet) for the work is built into a voltage detector, an accident can be prevented even if there is no monitoring person if the worker comes to wear the helmet. Of course, if a worker enters the work site without wearing a helmet and without a voltage detector, he / she could have caused a major accident called an electric shock. As a result, there was a problem that when an object dropped above the head, the impact force applied to the head could not be absorbed.
Furthermore, there is a problem in that the alarm is sounded and the worker is unaware of the alarm if the work site is noisy.
The present invention has been made for the purpose of solving the above problems.

The present invention has been made to achieve the above object.
That is, a protective member for protecting the head from impact is made of synthetic resin, and the protective member is detachably provided on a light and breathable work hat, and a voltage detector is provided between the protective member and the hat. It is equipped with a storage part that can be worn freely, so that workers can be freed from the heat of summer, and even if light, protection of the head is secured, and further, they can protect themselves from electric shock It is.

  In addition, the storage part is made integrally with the protective member, and the storage part is sized so that two voltage detectors can be stored. The body is protected.

In addition, since the protective member made to fit the inner shape of the cap is configured so that the flange portion is held by the folded portion of the cap, it can be used for work without any special measures after attaching the voltage detector. It can be built into a hat.
In addition, when the voltage detector detects a high voltage, it is a portable voltage detector that notifies the operator of the danger with vibration and warning sound. Is something you can do.

  As described above, according to the present invention, a protective member for protecting the head from an impact is made of a synthetic resin or the like, and the protective member is detachably provided on a light and breathable cloth work hat and the hat is attached to the protective member. Since the storage unit can be installed freely so that the electric detector can be installed between the two, the operator can be sure of measures against heat, protection from shocks even if light, prevention of electric shock, etc. is there.
