Description

  The present invention relates to a helmet that can be easily worn in a few seconds, and a method for wearing the helmet.

  Many people were affected by the Great East Japan Earthquake in spring. The important thing when an earthquake occurs is to protect your body first. If you are indoors, your body (especially your head) will be crushed from pillars, structures such as beams, furniture, etc. It is encouraged to hide under a desk or table.

  Secondly, the earthquake ends in tens of seconds, but if you do not evacuate to a safe place after that, there is a risk of fire, aftershock, and tsunami on the coast, so you need to act quickly. is there. However, when evacuating through a collapsed building, it is necessary to protect the head from falling objects, and hoods have traditionally been used. However, the strength of the hood was not so strong, and there was a risk of injury when falling objects hit the head, so wearing a general helmet was desired.

  In recent years, due to the advancement of earthquake prediction technology, when an earthquake occurs, a large shake called an S wave comes after a small shake called a P wave. However, it is reported as earthquake early warning on TV, radio and mobile phones. As the time, S wave comes after several seconds to several tens of seconds. However, although it is several seconds to several tens of seconds, the corresponding time can be provided, and the applicant can wear a helmet that can be worn on the head within the short time. Created.

  Examples of the invention of the helmet include Patent Document 1 and Patent Document 2.

  Thereby, when not in use, the piece member is kept flat, and the ring body maintained at the bent position of each piece member is disposed on each piece member, and thus becomes plate-like and does not become bulky. When used as a helmet, the center of each piece member is supported by the head, and by applying a force to move the ring to the end of each piece member, each piece member is bent and formed into a hemisphere as a whole. A helmet is made.

  The piece member preferably has a resinous outer shell on the outer side and a resinous elastic body on the inner side (Claim 2). The outer shell prevents damage from a falling part, and the elastic member provides a cushioning action. To absorb the shock to the head.

  Preferably, the connector has a stopper that engages with an end of the piece member (Claim 3), and is formed as a helmet when the ring is moved to the end of each piece member. When it hits, the position of the ring body is maintained by engaging with the end, and the hemispherical state of the helmet is maintained.

  The guide hole is preferably formed in the longitudinal direction (radial direction) of the piece member. Moreover, it is preferable that a chin string is attached to a ring body (Claim 5), and a movement of a ring body can be made easy by pulling a chin string.

  A cut hole space is formed between the multiple piece members adjacent to each other (Claim 6), and a desired hemisphere is formed by contact of the side portions of each piece member when the cutout space disappears. be able to.

  A helmet covering method according to the present invention includes a plurality of flexible piece members that are coupled in a central portion and are formed in a radial direction, and a ring body having a predetermined diameter provided on the plurality of piece members. And a helmet composed of a slidable connector and a chin strap attached to the ring body while being fixed to the ring body and locked in a guide hole formed in the piece member. By placing and then pulling the chin strap, the ring body moves, many pieces are bent, the notch space between adjacent ones disappears, and a hemispherical helmet is formed. (Claim 7).

Thereby, a helmet can be formed quickly and can be quickly mounted on the head.

As described above, according to the first aspect of the present invention, it is plate-like when not in use and can be suspended on the wall. Alternatively, a plurality of helmets can be stacked without being bulky, which is very convenient for storing them.
In use, the helmet is put on the head, and then the chin string is pulled to make a hemispherical helmet, which can be worn on the head in a short time such as several seconds. Therefore, the helmet of the present invention can be quickly worn even after the earthquake early warning is issued.

  According to the second aspect of the present invention, the resin outer shell is provided on the outer side to maintain the strength, and the inner elastic body is provided to absorb the impact on the head. According to the invention of claim 3, since the stopper provided on the coupling member is engaged with the end of the one member and the position of the ring body is maintained, the hemispherical state of the helmet can be maintained.

  According to the invention of claim 5, the chin string is attached to the ring. The mounting on the head is completed by an extremely simple operation of moving the ring body by pulling the chin string. Thereby, even an elderly person and an infant can be worn in a few seconds.

  According to the invention of claim 7, the helmet body having the configuration of claim 1 is placed on the head of a person, and then the chin strap is pulled to move the ring body, so that a large number of pieces are bent and adjacent to each other. The helmet covering method in which the notch space disappears and a hemispherical helmet is formed has the advantage that it can be attached to the head in a few seconds with a very simple operation.
