Definitions
- the present invention relates to a helmet provided with a vent for ventilating the inside of the helmet.
- a helmet is a relatively thick hat composed of a dome-shaped hard shell and a dome-shaped porous liner fitted inside the shell, so that when worn, hot air will Easy to hang. Helmets with vents on the front or front and back of the helmet are also commercially available to cool the hot air inside the helmet. The helmet draws outside air into the inside of the helmet through the ventilation holes on the front of the shell and exhausts the inside air to the ventilation top on the top of the shell or the ventilation holes on the back of the shell, thereby removing the hot air trapped inside the helmet. Let cool.
- a ventilation port frame is fitted to the ventilation port.
- the shell is stopped by the shell, and when the ventilation hole of the shell has a long hole, the shell is riveted or screwed to the shell.
- the work of fixing or riveting or screwing the ventilation frame on the curved surface of the dome-shaped shell to fit the ventilation hole drilled in the upper half of the dome-shaped shell is a skill. This requires a lot of time and effort, resulting in an increase in manufacturing costs.
- the conventional ventilation opening frame is an annular frame surrounding the ventilation opening, the outlet thereof is the same as the outlet of the ventilation opening, and the normal direction of the upper half inclined surface of the dome-shaped shell is used. Point diagonally downward along. For this reason, most of the inflowing air does not go directly to the upper part of the helmet, but instead bypasses the lower part of the helmet and reaches the upper part of the helmet. There was a problem that it was not enough.
- Patent Document 1 JP-A-63-59406
- a problem to be solved by the present invention is that a helmet is formed in the upper half of the dome-shaped shell.

- the ventilation holes formed in the shell of the dome-shaped hard helmet are separated from each other at the center and extend horizontally horizontally, circularly, or diagonally upward. It is preferable to form a pin hole near the center of the periphery of the ventilation opening and near the extended end of the hole.
- the periphery of the ventilation opening of the shell surrounding the ventilation opening forms a concave outer surface in which the outer surface sinks below the outer surface of the surrounding shell, and a convex inner surface in which the inner surface projects inward from the inner surface of the surrounding shell. It is preferable that the peripheral portion of the frame is fitted into the concave outer surface of the peripheral portion of the ventilation opening.
- the convex inner surface of the periphery of the ventilation opening is convenient for pressing the retaining ring.
- the ventilation port frame is a lip-shaped frame that smiles when the ventilation port is spaced apart from the center and extends horizontally or horizontally in an arc or two symmetric slots.
- an airfoil-shaped frame In the case of two symmetrical long holes whose mouths are separated from the center and extend diagonally right and left, it is preferable to use an airfoil-shaped frame.
- Two to six nozzles of the ventilation port frame are symmetrically arranged in a row, and the inner cross section of each nozzle is reduced to the outlet side to increase the speed of the taken-in air, and the outlet at the tip is horizontal.
- the ventilation opening frame and the shell are formed.
- the fit of the exterior material is improved.
- the retaining ring can be externally fitted to the pin of the ventilation port frame body that has penetrated the pin hole with a tool and pressed against the convex inner surface of the ventilation port peripheral edge of the shell, for example, formed on the inner circumference. It is preferable that the inner diameter can be expanded sexually by a plurality of cutouts formed.
- the helmet 1 is provided with ventilation openings 2 before and after a shell 4 covered with an exterior material to take in outside air.
- the ventilation port 2 is provided with a smiling lip-shaped ventilation port frame 3 that extends symmetrically in an arc shape.
- a ventilation port 2 is formed in the upper half of the hard dome-shaped shell 4 of the helmet, and an outer material 5 is coated on the outer surface.
- Ventilation frame 3 is attached to ventilation port 2 Is done.
- the outer surface of the ventilation port peripheral portion 6 surrounding the ventilation port 2 of the shell 4 forms a concave outer surface 13 which sinks slightly from the outer surface of the surrounding shell 4.
- the frame peripheral edge 7 of the ventilation port frame 3 fits into the concave outer surface 13.
- a nozzle 8 is formed inside the frame peripheral edge portion 7, and the nozzle 8 fits inside the ventilation port 2 from outside.
- the inner surface of the peripheral edge 6 of the ventilation opening forms a convex inner surface 14 which projects slightly inward from the inner surface of the shell 4 around it.
- a dome-shaped porous liner is also fitted inside the shell on which the ventilation frame is mounted.
- the frame peripheral portion 7 of the ventilation port frame 3 fits into the concave outer surface 13 of the ventilation port peripheral portion 6 of the shell 4.
- the periphery 7 of the frame has a smiling lip shape extending symmetrically in an arc shape, and has four nozzles 8 formed therein.
