Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a helmet worn by a worker at a work site to protect his head.

[0002]

[Prior art]

 Conventionally, there are various types of helmets for head protection used at construction sites and construction sites. This helmet is composed of a strong outer body for safety and a head mounted body that directly wears on the head.When wearing the helmet on the head and performing various work outdoors or indoors, I am trying to be safe. However, in the helmet, the space provided between the outer body and the head ornament is narrow, so that the air flow is poor. In particular, when working outdoors in hot seasons such as summer, the temperature inside the helmet increased significantly due to the sunlight, which caused distracting attention and increasing the risk of accidents.

In order to prevent the temperature inside the helmet from rising, a fan is attached to the helmet to blow air to lower the temperature as much as possible to prevent accidents in various works at the construction site. However, these blowers cool a worker's head by attaching a small fan to the top or rear of the helmet to force external air into the helmet.

[0004]

[Problems to be solved by the device]

 As mentioned above, helmets that are worn to protect the head of workers at various construction sites and construction sites are required to ensure the safety of the workers' heads. It is required to prevent the work environment from deteriorating because it is muddy. Therefore, when mounting a motor box containing a fan and a motor in the helmet, the helmet was likely to collide with surrounding objects because the motor box protruded from the surface of the helmet. Such a collision easily causes a failure, and since the power source of the motor for rotating the fan has to be attached to the waist of the worker, the workability is poor. .

In the present invention, when the outdoor work is performed in a hot season such as summer, the solar battery is attached to the outside of the helmet, and the cooling member cools the wind blown into the helmet to forcibly lower the temperature inside the helmet. The purpose is to improve the working environment.

By mounting a large number of solar batteries 19 on the entire surface of the daily removal piece 51, the battery capacity can be increased and the driving force of the motor 6 can be increased. Further, when the work is hindered or the sunlight is not so hot, it is possible to remove the solar remover 51.

Next, the operation of the first embodiment of the present invention will be described. When the first helmet 1 is used, the accommodation chamber 8 provided in the lower portion of the motor box 4 mounted inside the outer body 2 is described. A large number of outlets 9 are provided on the lower surface. A cooling member (simple refrigerant) 45 is housed in the housing chamber 8 so that it can be taken in and out as required, and a solar battery 19 mounted on the surface of the outer body 2 and a motor in the motor box 4 are housed. A switch (not shown) for electrically connecting to the motor 6 is turned ON to drive the motor 6, and the fan 7 is rotated to generate a negative pressure in the motor box 4 to thereby generate the motor. External air is sucked through the intake port 5 in the upper part of the box 4. When this air passes through the inside of the motor box 4 and passes through the inside of the accommodation chamber 8 provided at the lower part of the motor box, the air contacts the cooling member 45 accommodated in the accommodation chamber 8 Is cooled down, passes through the space 18 from the air outlet 9 provided on the lower surface of the accommodation chamber, sends cool air to the head through the through hole 16 of the head mounting body 15, and the inside of the outer body 2 becomes hot. It pushes out air and cools it.

Since the space 18 provided between the outer body 2 and the head mounting body 15 is wide, a motor box can be accommodated, and a space between the lower portion of the head mounting portion 15 and the periphery thereof is narrow. Since the air cooled by the cooling member 45 stays in the space 18, the head mounting portion facing the space can be cooled and the inside of the outer body 2 can be cooled. Even if a strong impact is applied to the helmet from the outside, the outer body 2 has sufficient strength to absorb the impact and protect the head of the worker safely. .

Next, the operation of the second embodiment will be described. When the second helmet 21 is used, the lid body 29 attached to the lower surface of the second accommodating portion 27 provided at the lower portion of the second outer body 22 is described. Is removed to house the cooling member 45. Since no protrusion is provided on the surface of the outer body 22, it is prevented from being caught by an external obstacle during the work, and the second motor box 31 is prevented from being broken and the fan not rotating. You can wear this helmet and work with confidence. A plurality of solar batteries 19 buried in the surface of the outer body 22 and a motor 33 in a motor box 31 are electrically connected, and a switch (not shown) is turned on. Rotate 34.

Due to the negative pressure generated in the second motor casing 31 by the rotation of this fan, external air is discharged from the lower end portion of the second space portion 37 provided between the outer body 22 and the inner body 26. Take it in and suck in the direction of the second motor box 31. The second motor box 31 is cooled when it comes into contact with the cooling member 45 exchangeably accommodated in the accommodating chamber 27 and passes through the second motor casing 31 and is cooled by the second cover provided on the lower lid 29. The cool air is blown from the outlet 30 to the head of the worker who wears the second head mount 41 to cool the head and absorb the heat.

When the required electric power cannot be obtained only with the capacity of the solar battery 19 provided on the surfaces of the first and second helmets 1 and 21, as shown in FIG. Further, a daily strip 51 made of a cloth or a flexible synthetic resin material, which is detachable and has a certain degree of strength, is detachably attached. By mounting a large number of solar batteries 19 on the surface of the sunshade 51, necessary and sufficient power can be obtained, and sunburn from the nape of the neck to the shoulder can be prevented, or the shoulder can collide with an obstacle. It is possible to absorb the shock when it is made. Furthermore, because it covers the back of the neck, it is possible to temporarily avoid a sudden attack of a crow or a wasp from the back during outdoor work.
