In the helmet shown in FIG. 4, a transparent part 10 is provided partially on the cap body 1 and the light emitting part 2 is made to correspond to the transparent part 10 from the inside of the cap body 1 by using, for example, an adhesive tape or an adhesive. And the like. here,
The transparent portion 10 includes a so-called translucent portion that transmits a part of the light, in addition to a portion that transmits the entire light.

The method of forming the transparent portion 10 on the cap body 1 is as follows. The transparent portion 10 is formed in advance into a desired shape with a transparent resin (polycarbonate resin or the like), and is previously formed in a mold for forming the cap body 1. After setting the transparent portion 10 at a desired position, a normal non-transparent resin (polycarbonate resin or the like) is poured into the mold of the cap 1 to form the transparent portion 10 integrally (such a cap 1 Is referred to as insert processing).

Further, the light-emitting portions 2 and 2 'can be formed integrally with the cap body 1 by insert processing. That is, the light emitting units 2, 2 'are set in a mold for forming the transparent unit 10 in advance, and the transparent resin 10 having the light emitting units 2, 2 is formed by pouring a transparent resin into the mold. I do. Further, the transparent portion 10 may be formed by setting a mold for forming the cap 1 and then pouring a normal non-transparent resin into the mold of the cap 1. By such an insert processing method, the light emitting units 2 and 2 ′ may be formed integrally with the cap body 1.

As shown in FIG. 4, when the transparent portion 10 is partially formed on the cap 1, the entire surface of the cap 1 is not transparent, so that the helmet having no shock absorber (so-called shock absorbing liner) is provided. In the case of (1), the head is prevented from being irradiated at the time of daytime work outdoors.

Further, as shown in FIG. 5, the transparent portion 10 (the hatched portion in FIG. 5) corresponding to the position where the light emitting diode emits light is formed by the above-described insert processing.
It is also possible to form them. In addition, as a method of applying the transparent portion 10 to the cap body 1, in order to use the helmet as a genuine product which has passed the above various certification tests of the Ministry of Labor, leave the transparent portion 10 on the transparent cap body 1 formed of transparent resin. There is a method of applying a pigment.

According to the first aspect of the present invention, since the point-like illuminant is located on the transparent portion of the cap and fixed to the inner surface of the cap, there is no attachment / detachment of the point-like illuminant. Since the usability of the helmet is improved and the point-like illuminator is mounted inside the helmet, the luminous body does not hit an external protrusion, so that the functionality as the helmet is also improved. Further, since the point-like illuminant emits light by itself, the presence of the illuminant can be known even when light is not radiated from the outside as in a conventional reflective tape. Further, since at least the cap portion for fixing the light-emitting portion is made transparent, even if the light-emitting portion is fixed inside the cap, the lighting of the light-emitting portion can be visually observed from the outside. Since it can be informed and does not require processing to make a hole in the cap body, it passes various certification tests of the Ministry of Labor, so it can be used as an industrial helmet for all work sites. Further, since the cap body has no opening such as an eyelet, rainwater does not enter the helmet and the mechanical strength does not decrease.

Next, according to the third aspect of the present invention, a plurality of point-like illuminants are provided at the rear of the helmet so as to notify the presence of the rear that is not in the field of view of the wearer. Sudden impact and trauma can be prevented. In addition, since the number of the point light emitters is relatively small, the efficiency is high because the number is limited to the rear part of the helmet. In addition, depending on how the point light emitters are provided, it appears that light is emitted linearly or in a planar manner, so that a light emitting portion can be provided depending on the application.

According to the fourth aspect of the present invention, since the fixing band and the lighting circuit are housed in the case and the case is fixed to the transparent portion of the cap, the occupancy of the inside of the cap can be reduced. Because it is visually excellent.

According to the fifth aspect of the present invention, the fixing band and the lighting circuit are connected by a conductive wire, the fixing band is fixed to the transparent portion of the cap, and the lighting circuit is fixed to the inner peripheral edge of the cap. The light-emitting part can be turned on and off while wearing a helmet, improving its usability.

According to the sixth aspect of the invention, since the transparent portion of the cap can be formed in a desired shape corresponding to the light emitting portion, the other portion is formed of a non-transparent resin. In the case of a helmet without a shock absorber, it is possible to prevent irradiation of the sun.

According to the seventh aspect of the present invention, since the transparent portion is formed by the insert process, the transparent portion and the cap are integrated, so that the same strength as that of the cap formed of the same resin can be obtained. Obtainable.

According to the eighth aspect of the present invention, the point-like illuminant is integrated with the transparent cap or the transparent portion by insert processing in the process of forming the transparent cap or the transparent portion with the mold. Since the cap is fixed, it is not necessary to fix the point light-emitting body to the inner surface of the cap with an adhesive tape or the like after the cap is formed, so that the production efficiency is good and the appearance is good.
