Description

    The present invention relates to a cooling helmet that cools a wearer's head with cold air.

    Workers are required to wear a helmet from the viewpoint of ensuring safety at construction sites such as construction work and electrical work. Is required.

    By the way, when wearing in hot summer, especially under hot weather, the temperature inside the helmet rises due to sweating of the head and obstruction of heat dissipation, resulting in unpleasantness, uncomfortable feeling and reduced work efficiency as well as danger. Also increases.

    In order to solve these problems, a technique has been proposed in which an electric motor is provided in a helmet and a fan is rotated thereby to perform ventilation.

However, in this technique, since it is ventilation cooling by forced rotation of the fan, the cooling efficiency is poor and the immediate effect is inferior, and the entire head cannot be cooled instantaneously.
Utility Model Registration No.2593945

    The present invention has been made on the basis of the above circumstances. The object of the present invention is to apply the present helmet easily without any change, instantly cool the entire head, An object of the present invention is to provide a cooling helmet that can eliminate discomfort due to heat when worn, prevent a reduction in attention, a decrease in work efficiency, and the like, and improve work safety.

    For this purpose, the cooling helmet according to claim 1 of the present invention includes a paper head cap provided on the inner side of the outer grain that protects the head of the helmet, and is folded on the inner surface of the head cap. A cooling bag made of a moisture permeable sheet that is partially bonded in a state, and a portable cold air spray that is inserted into a fitting hole of the head cap and the cooling bag and provided via a pipe, High-pressure cooling gas from the spray is injected into the cooling bag through the pipe, and the cooling bag temporarily expands into a spherical balloon shape, so that cold air flows over the entire head of the wearer and the head is cooled. It is characterized by the structure.

    In the cooling helmet according to the present invention, a moisture-permeable sheet cooling bag is partially bonded to the inside of an existing paper head cap provided inside the outer grain that protects the wearer's head in the helmet. As such, it can be constructed without any structural changes to the existing helmet.

    Further, the cooling helmet according to the present invention is cooled by the cold air from the moisture-permeable sheet cooling bag swelled by the high-pressure cooling gas from the cold air spray through the pipe into the moisture-permeable sheet cooling bag. Therefore, cold air instantaneously flows over the entire head and is cooled.

    In addition, the cooling helmet according to the present invention has a cooling bag formed of a waterproof moisture-permeable sheet that allows air (cold air) to pass but does not allow moisture to pass through. Therefore, the cooling gas ejected from the cooling spray is moisture in the air. When touched, some moisture is generated, but this moisture collects at the bottom of the cooling bag (the portion touched by the forehead, the back of the head, and the side), and is further cooled by this moisture to improve the cooling effect.

    The best mode for carrying out the invention according to the present application will be described below together with its operation with reference to the drawings.

    FIG. 1 is an explanatory view seen from the side of a partial cross section in an example of a cooling helmet according to the present invention, FIG. 2 is a plan view of the main part, FIG. 3 is a partially enlarged cross-sectional view of FIG. It is explanatory drawing which shows the swelling of a cooling bag.

    In FIG. 1, the cooling helmet according to the present invention includes a paper head cap, a moisture-permeable sheet cooling bag, and a portable cool air spray.

    The paper head cap 3 is provided inside the outer grain 2 that protects the wearer's head in the helmet 1. This head cap 3 is for preventing dirt in the outer shell 2 due to the hair material of the wearer, and is usually disposable.

    In the case of a known helmet, when a shock absorbing liner (not shown) made of a polystyrene fired 20 times is fired inside the outer shell, a paper head cap 3 is provided inside the shock absorbing liner. .

    Inside the paper head cap 3, a cooling bag 4 into which high-pressure cooling gas is injected is provided.

    When the cooling bag 4 is inflated by a waterproof moisture-permeable sheet that allows air (cold air) to pass through but does not allow moisture to pass through, for example, a waterproof moisture-permeable sheet in which a polyethylene porous film and a nonwoven fabric are thermally bonded, it forms a spherical balloon. It is formed to become.

    The cooling bag 4 has a pipe insertion hole 6 in communication with the pipe insertion hole 5 of the head cap 3 opened on the center upper surface side, and the cooling bag 4 is in a folded state and the upper surface side is the head side The cap 3 is attached to the inner peripheral surface of the cap 3 through an adhesive 7 and is temporarily inflated into a spherical balloon shape by injection of a high-pressure cooling gas described later.

    The portable cool air spray 8 is preferably a portable gas cylinder 9 having a size enough to fit in a breast pocket, a push nozzle 10 attached to the head of the cylinder 9, one end connected to the nozzle 10, and a free end. Is composed of a pipe 11 inserted into the pipe insertion holes 5 and 6 through a space 12 between the helmet outer grain 2 and the head cap 3.

    The present cooling helmet configured as described above is worn in a state where the cooling bag 4 is folded.

    When the nozzle 10 is pushed after wearing the helmet, the non-combustible high-pressure cooling gas (nitrogen gas) in the cylinder 9 passes through the pipe 11 from the pipe insertion holes 5 and 6 into the cooling bag 4 as shown in FIG. Is temporarily inflated into a spherical balloon shape, but because of its high air permeability, cold air as low as −40 ° C. blows out instantaneously, and the cold air flows over the entire head, and the cold air can be felt.

    In this way, the cooling bag 4 temporarily swells slightly in the shape of a spherical balloon and the cold air does not stagnate in the cooling bag 4, but the cooling bag 4 is deflated into a balloon shape by the discharge of cold air, Moisture is generated by dew condensation when exposed to moisture in the air, but this moisture collects at the bottom of the cooling bag 4 (where the forehead, the back of the head, and the sides touch), as shown by the diagonal lines in FIG. The head is further cooled by this moisture, and a double cooling effect is obtained.

    There is no problem because the water accumulated in the cooling bag 4 is a little so that it evaporates due to the heat of the head and does not accumulate for a long time.

    The present invention can be applied to a hat in various sports in addition to a cooling helmet, and can also be provided as a cooling hat.

It is explanatory drawing seen from the side of the partial cross section in an example of the cooling helmet which concerns on this invention. It is a top view of the principal part. FIG. 2 is a partially enlarged cross-sectional view of FIG. It is explanatory drawing which shows the swelling of a cooling bag.
