Description

Cooling helmet

The present invention relates in particular to a head wearable which can be worn in accordance with a wearer who requires an anti-shock function.

It is well known to place ice near a person's head for cooling purposes for medical purposes.

For example, it is known to cool the head surface by covering the head with a flexible material capable of holding a cooled liquid. This method is used to reduce damage to hair follicles of people taking cancer medications. Otherwise, your hair may fall out.

One prior art, published in connection with a practical head wear that provides a shock resistant and includes a temperature modifying material, supports a pocket with a brittle pocket encapsulated with ammonia salt in the body of water. It is a helmet of composition. The inner pocket is fitted to the inside of the helmet and is positioned such that it is held in position by a hook and hook fastening pad (often referred to as the registered trademark 'velcro'). Unfortunately, in this prior art the use of brittle pockets in inner pockets is used in place of soft fillings, and the liquid inner pockets are in direct contact with the user's head.

This is because the heat transfer from the user's head by the direct conductivity of the inner pocket, there is a disadvantage that heat transfer does not occur well for other parts of the head. This causes a severe temperature difference for the head, similar to putting an ice pack on the head, which must be very uncomfortable after some time.

The effect of replacing part of the filling is that the filling can be exchanged without the helmet itself being intact, which still requires separate testing.

The more difficult thing with direct contact is that the temperature deforming material is in direct contact with the user's head, so that the maintained temperature difference will be compensated relatively quickly. In other words, by making direct contact, the cooling effect can only last for a relatively short time, for example.

In view of the above problems, the present invention has a more comfortable structure employing a heat deformation means, and at the same time provides a shock protector of the head fitting which can increase its time so that the cooling effect can be continued.

The invention will be more clearly understood by the embodiments described with reference to the following figures.

Referring to Figure 1, there is shown an impact resistant helmet that may be worn by a user, such as a batter in a traditional game such as cricket.

The helmet 1 has a crown-shaped inner portion 2 molded from an impact resistant plastic material such as fiber reinforced polyester. It also provides a part comprising the hat brim 19 and the side which are connected to each other as two areas of the lower part 2.

In the form of a head, there is provided an impact resistance outer part 6 having a dome shape, which has a lower edge coinciding with the circumferential part 7 of the lower part 2, with a cavity 8 formed therebetween.

The cavity 8 is formed to receive a pack 9, which packs two flexible plastic materials together along the inner joint 10 and the outer joint 11, thereby providing a pocket. And a through center hole 13.

Pouch 12 contains a cooling gel, which is typically cooled at temperatures below 0 ° C., which once melted provides a cooling effect accordingly.

The outer part 6 is held at the position of the bolt 15 protruding upward while being embedded in the central portion of the inner part 12 through the through hole 16 and engaged with the nut 17.

The opening 18 is formed to be distributed in the inner portion 12 to allow air to flow from the cooling gel into the air space below the inner portion 12.

Hat brim 19 is protruded forward from the inner portion 2, the leather strap 19a is provided to support the helmet to the user's head.

Although not specifically shown, a configuration typically used is a leash that runs from side to side and passes over the user's head and is a means for supporting an inner portion just above the user's head or hair or skin, ie, the bottom of the helmet. In another case, a separate block of filler material 21 is located around the inner circumference of the inner part 2, which is spaced apart from one another to allow access and flow of air to the user's head.

In practice, this configuration provides a very convenient structure in which the outer side 6 is customly combined with the lower shell or tubular shape of the inner side 2 so that the outer appearance looks similar to a conventional helmet shape.

The pack 9 can be removed from time to time by loosening the nut 17 and lifting the outer portion, and by replacing it with another cooling pack, the user wearing the hat can maintain the cooling effect for a long time.

As shown, the present invention can provide superior protection by plastic materials of similar thickness and type compared to conventional single wall structures by the double wall structure of the outer and inner portions. In addition, the normal protective properties for this type of helmet can be maintained by employing a cooling gel structurally supported by self-supporting means, while the structure of such a helmet can be provided by a conventional separate filling or by a leash. Can be maintained. In addition, there is no direct contact of the cooling bag with the user's head or skin.

Many users enter competitions where they must wear protective headgear, which can be a potential problem when they have a fever. Such games include cycling, baseball, lacrosse or football.

In each case, specialized helmets have been developed for their use. Those skilled in the art should understand that the foregoing configurations can be applied to such helmets.

3 and 4, there is shown a helmet for use by a construction worker at a building site, called a hard hat.

The helmet 20 has an outermost shell with an outer portion 22 molded from a suitable impact resistant plastic material, such as a polycarbonate plastic material, like a conventional building helmet.

Moreover, the heat insulating material 24 in which the cavity part 30 which has a dome shape is formed so that the circumference part 26 of the inner side part 28 may be provided is provided. The outer portion 22 and the inner portion 28 have a dome shape, and the inner portion 28 is located in the outer portion 22.

The cavity 30 houses a pack 32 therein, the pack comprising a coolable gel. The pack is provided by joining a flexible plastic material along the inner joint 34 and the outer joint 36 to form a pouch 38.

Inside the pouch 38 is a cooling gel, which is typically cooled at temperatures below 0 ° C., which once melted provides a cooling effect accordingly.

The insulation 24 and the inner portion 28 may be joined together and then secured entirely to the outer shell by a helmet leash 40, as shown by the dashed line, as such a configuration is found in a conventional helmet structure. It can be attached to and detached from the outer shell by means of the clip 42 for engaging the outer shell 22.

In this case, the hat brim 43 is a part of the outer portion 22, so that the inner portion is coupled to the outer portion 22.

Such a helmet leash configuration can be easily detached, for example, to replace a pocket 38 that is no longer cooling for another cooling pack.

In other words, the cooling material is arranged such that it does not make direct contact with them on the user's head or skin, thus allowing for circulation of air, good thermal insulation, and control of air flowing through the cooling material.

Another advantage of this configuration is that cooling is possible by economically and simply modifying a conventional hard hat already produced in large quantities. This allows people who have been unable to work for a long time, especially because they work outside, to continue working at high temperatures for a long time.

As hard hats are mandatory in many factories and construction sites, and their design has become an important development task, this simple application will be very encouraging for the cooling function.

Various other types of occupations require protective headwear, including firefighters and welders. In such cases, specialized helmets have been developed according to the strict standards required by each occupation. Those of ordinary skill in the art should understand that the foregoing configuration can be applied to such a helmet.

Referring now to FIGS. 5 and 6, there is shown a hat 50 called a conventional baseball cap made primarily of fiber material. In this case, the hat includes a piece of cloth 51 constituting the head tube 52, and includes a hat visor 53 protruding from one side of the circumference of the head tube. Furthermore, since the fabric piece 51 is designed with a spandex material, the head shape is stretchable and is made of multi-size that can be comfortably worn on various sizes of heads. Although not specifically illustrated, an elastic inner sleeve wrapped with a towel cloth ( 53a). This provides more comfortable stretch.

Inside the head tube is provided an outer portion 54 having a dome shape made of impact-resistant plastic material, which is adapted to fit the circumferential portion 56 of the inner portion 58. An inner portion 58 is located within the outer portion 54, and a cavity 60 is formed between the inner portion 58 and the outer portion 54, which are the outermost portion, that is, the head tube 52 of the cap 50. It is located inside. The outer portion 54 and the inner portion 58 can be simply located by friction between the stretchable tubular material and the outer edge of each portion.

The cavity 60 receives a pack 62 therein, which joins two flexible plastic materials along the inner joint 64 and the outer joint 66 to form a pocket 68. will be.

The bag 68 contains a cooling gel, which is typically cooled at temperatures below 0 ° C., once melted to provide a cooling effect accordingly.

The shells 54 and 58 are supported as described above and are generally capped to accommodate the innermost shell at their center by screws 70 and buttons 76 commonly found on the head of the cap. Is fixed to

This structure makes the bag 68 detachable, thereby facilitating the exchange of another cooling bag 68.

This design allows applications such as golf to be used for both cooling and the impact protection of a golf ball. This design allows the capillary itself to be supported on the head by engaging the elastic sleeve to the user's head. In practice this means that air space remains on the top of the user's head and on the inner bottom of the hat despite the multiple parts and gel pockets.

In each embodiment, configurations of the inner and outer sections are provided, and although the configuration of the through-holes through each of these sections is not specifically illustrated, the size and position adjustment necessary for maintaining the insulation as compared to the air flow for the cooling effect, etc. Can be done.

There are different types of hair wears. Those skilled in the art will understand that the foregoing configurations can also be fully applied to those types.

The above-described invention has been found to bring benefits of increased comfort and safety while being very convenient for those who need to use or wear hats and hard hats for protective purposes, especially in hot working conditions.
