Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a headgear for protecting the head from impact.

BACKGROUND OF THE INVENTION In recent years, as a result of seeking a balance between safety and practicality in various martial arts, it has become increasingly common to wear protective gear on various parts of the human body during matches. In particular, in view of the fact that head injuries are the most fatal among injuries to the human body, headgear wear rates are high and the demand for it is rapidly increasing.

Therefore, conventional headgear is generally provided with a skin portion shaped to cover the head, and a shock absorbing member is housed inside the skin portion.

Problems that the invention aims to solve: However, since the inner surface of the epidermis is in close contact with the head on its entire surface, the peak of the impact locally increases in the area that received the impact in response to a specific impact. It ends up. Therefore, the shock absorption rate is poor,
It has the disadvantage that it cannot effectively protect the head.

The present invention was devised in view of these points, and an object of the present invention is to obtain a headgear that can effectively protect the head.

Means for Solving the Problems The present invention provides a skin part having a shape that covers the head, stores a shock absorbing member inside this skin part,
This shock absorbing member formed wavy protrusions projecting inward on the inner surface of the skin portion.

Function: When the outer surface of the epidermis receives an impact, the protrusions on the inner surface that are closest to the area that was first impacted are flattened, and the protrusions adjacent to these are crushed in turn. Here, the impact is transmitted through each protrusion and spreads throughout, and at this time, the impact is not concentrated locally but is dispersed throughout. Therefore, the impact absorption rate is increased and the head is effectively protected.

Embodiment of the invention An embodiment of the invention will be described based on FIGS. 1 to 5. Epidermis 1 having a shape that covers the head
is provided. The outer skin part 1 has a substantially cylindrical shape with a part cut out to expose the face, and the outer fabric 2 and the lining 3 are sewn together at their ends. Here, the outer material 2 is made of 100% polygon rubber coated cloth. The lining 3 is
Made of 100% polyester rubberized knitted fabric. A shock absorbing member (not shown) is housed inside the outer skin portion 1, that is, between the outer material 2 and the lining material 3. This shock absorbing member is basically made of synthetic rubber made of single foam polyethylene and vinyl acetate.

On the other hand, the epidermis 1 has a frontal protection part 4, an occipital protection part 5, and a temporal protection part 6 on the front, back, and side surfaces, respectively.

The forehead protection part 4 has a wavy protrusion 7 formed on its inner surface and protrudes inward. That is,
The shock absorbing member in this part is formed in a wavy shape, and the wavy peaks appear on the lining 3 and form the protrusions 7.
is formed.

A reinforced shock absorbing member is used for the occiput protection part 5. In other words, in addition to regular shock absorbing materials, ZDEL developed by Bridgestone Corporation
is stored. This ZEDL has excellent shock absorption rate and low specific gravity.

A pair of ear protectors 8 are provided on the temporal protector 6 . These ear protectors 8 are
It is located in the same plane with respect to the outer surface of the temporal protection part 6, has a protruding shape with respect to the inner surface of the temporal protection part 6, and has an open hole 9 in the center. Further, the ear protector 8 has a plurality of air vent grooves 10 at an end portion protruding from the inner surface of the temporal protection portion 6.

Further, an adjustment hole 11 is provided at the top of the skin portion 1.
is provided. A plurality of ring-shaped latching bands 12 are arranged at the edge of the adjustment hole 11 toward the center of the adjustment hole 11, and an adjustment string 13 is stretched around these latching bands 12. ing.
Further, a chin strap 14 is attached to both lower ends of the temporal protection part 4 in a freely expandable and retractable manner.

In such a configuration, the outer skin part 1 is worn on the head. The chin strap 14 is hung on the chin, and by adjusting the size of the adjustment hole 11 and the length of the chin strap 14, the shape of the outer skin part 1 can be changed to suit the wearer's head. It is possible. The size of the adjustment hole 11 can be adjusted by changing the position of the knot of the adjustment string 13 and changing its length.

On the other hand, the impact applied to the forehead protector 6 is alleviated by the protrusion 7. That is, when receiving a specific impact, on the inner surface of that part, the protrusion 7 closest to the part first collapses into a flattened shape, and the protrusions 7 adjacent thereto are crushed one after another. Here, the impact is transmitted through each protrusion 7 and spreads throughout, and the impact at this time is not concentrated locally but is dispersed throughout. When the impact is dispersed in this manner, although the impact energy itself remains unchanged, the energy at the highest impact peak is reduced, resulting in an increase in impact absorption rate. The head is therefore effectively protected.

Further, since a reinforced shock absorbing member is used in the occiput protection portion 5, the shock to this portion is sufficiently alleviated. In the first place, injuries caused by falling after losing consciousness and hitting the back of the head on the floor often affect human life, but the back of the head protection section 5 reliably prevents such a situation.

Furthermore, the ear protector 8 protects the eardrum from damage and prevents the epidermis 1 from shifting relative to the head. That is, when the open hole 9 is blocked by an attack from the side of the epidermis 1, a sealed space is formed between the ear protector 8 and the head where the ear is located, and the pressure in this space is reduced. It can become high enough to damage the eardrum. However, in response to such a situation, air vent groove 1 is installed before forming the sealed space.
0, the air at the position is expelled, and pressure rise within that space is prevented. In particular, when wearing gloves, there is a very high probability that the attacker's hook or shin during an upper roundhouse kick will block the open hole 9, and in such a case, the eardrum will be effectively protected. On the other hand, since the ear protector 8 does not protrude from the outer surface of the epidermis 1, the ear protector 8 will not be affected by an attacker's attack applied to that part. Here, the position of the epidermis 1 relative to the head is prevented from being displaced from any attack by the attacker, contributing to improved safety during matches.

As described above, since the front head protection part 4 and the occipital protection part 5 have excellent shock absorption rates, sufficient safety is ensured even if the entire body is made lightweight.
Here, the fact that the entire body is lightweight is effective in suppressing the physical exhaustion of the wearer, and further contributes to preventing unexpected accidents that may occur due to physical exhaustion.

In addition, in implementation, other materials such as leather may be used for the outer material 2 and lining 3 of the outer skin portion 1, and other types of shock absorbing members may be used.

Effects of the invention This invention forms wavy protrusions that protrude inward on the inner surface of the skin part that houses the shock-absorbing member, so that the applied shock is dispersed over a wide range, increasing the shock absorption rate. Therefore, the head can be effectively protected, and since it has excellent shock absorption rate, the entire body can be made lightweight, which reduces fatigue caused by wearing it and improves safety. It has the effect of contributing.
