Definitions
- the present invention relates to a riding helmet provided with ventilation holes on the front and rear surfaces for cooling the inside by running wind. Background technology
- the riding helmet consists of a rigid dome-shaped shell, a similarly domed porous liner fitted inside the shell, and an interior that contacts the wearer's head inside the liner. It consists of materials. Riding helmets are 'relatively thick hats, so it is easy to get inside when wearing them.
- a well-known ventilation top consisting of a umbrella-shaped bag nut and a ported vent with a vent.
- the ventilation top is mounted in a zenith hole that passes through the zenith of the shell and liner.
- the hot air generated from the head passes through the zenith hole from the inside of the liner and is discharged to the outside air through the ventilation top '.
- Riding helmets are also commercially available that have vents before and after the helmet that extend from the outer surface of the shell to the inner surface of the liner. This helmet cools the hot air trapped inside the liner by taking in the wind from the front through the vents, passing between the inside of the liner and the interior material, and discharging through the rear vents. ,
- horse helmets equipped with conventional ventilation tops and ventilation holes are mainly designed to exhaust hot air inside the liner and do not cool the hot air trapped inside the liner, so the cooling effect is not necessarily satisfactory. It cannot be done.
- conventional hermets are expected to provide a sufficient cooling effect of hot air trapped inside the liner in the upper region of the helmet, which is heated to the highest temperature due to solar radiation. I can't wait. Disclosure of the invention
- the problem to be solved by the present invention is that a conventional riding helmet with a ventilated top and vents cools the hot air trapped inside the liner in the upper area of the helmet, which is the hottest in the sun. That is not possible.
- Means adopted by the present invention to solve the above problems include a dome-shaped hard shell, a dome-shaped porous liner fitted inside the shell, and a dome-shaped porous liner provided inside the liner.
- a front ventilation hole is provided on the front side of the shell, and a rear ventilation hole is provided on the rear side.
- a cooling passage communicating with the front and rear ventilation holes passing in the direction is provided.
- the traveling wind flowing from the front ventilation hole located in front of the shell passes through the cooling passage extending in the front and rear directions on the outer surface of the upper area of the liner, and the wind of the shell moves. Exhaust through rear vent.
- the riding helmet of the present invention sufficiently absorbs the hot air trapped inside the liner in the uppermost region of the helmet, which has the highest temperature, by the air flow passing through the groove-shaped cooling passage formed in the upper outer surface of the liner. It has an excellent effect of discharging wastewater.
- the shell is made of a hard synthetic resin
- the liner to be fitted on the inner surface of the shell is preferably made of a synthetic resin foam.

It is preferable that front and rear sinks are provided on the outer surface of the liner, the front vent and the cooling passage are communicated via the front sink, and the rear vent and the cooling passage are communicated via the rear sink.
- the front sink is cut in the front center of the outer surface of the liner, and the rear sink is cut in the center of the rear surface of the liner as a long groove in the left and right direction.
- Driving air enters through the front vents located at the front of the seal, enters the front sink on the outside of the liner that communicates with the front vents, and then passes through the cooling passages that extend the top area of the liner in the front-rear direction. Therefore, the hot air trapped inside the liner is cooled by heat exchange, and then discharged from the rear vent through the rear sink located on the rear surface of the outer surface of the liner.
- a well-known ventilation top is installed by drilling a zenith hole that penetrates the heavens of the shell and the liner, and at least a front sink, a rear sink, and a cooling passage are installed.
- One is to drill a communication passage that opens into the inner surface of the liner. It is preferable that a plurality of the communication passages are provided and provided symmetrically.
