JP3056262U - Inner cap for helmet - Google Patents

Abstract

(57) [Summary] [PROBLEMS] To provide an inner cap body which can be worn under a helmet, and can efficiently maintain the coolness of the head under the scorching sun for a certain period of time. SOLUTION: In the present invention, a bowl-shaped bag body is made, and a compressed cotton having a wall thickness of 5 mm to 15 mm is applied to a zenith part, and 2 m is provided on a peripheral side part.
Compressed cotton is embedded in a wall thickness of m to 8 mm.
At this time, the water absorbent resin is attached to the compressed cotton surface,
For example, a mesh fabric may be used for the cap body forming fabric in order to increase the water permeability.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a helmet inner cap body.

[0002]

[Prior art]

 Outdoor workers and drivers such as motorcycles wear helmets made of metal or synthetic resin to protect their heads, but the helmet itself becomes hot in the hot summer months. There is a problem, and as a countermeasure for this, devising the material or sticking a special cloth inside the helmet has been performed.

[0003]

[Problems to be solved by the invention]

 The present invention does not devise the helmet itself, that is, the helmet is used in the conventional way, by wearing a specially configured inner cap body on the top of the head when wearing a hat, The task is to make it easy to take measures against hot air under hot weather.

[0004]

[Means for Solving the Problems]

 According to the present invention, a bowl-shaped bag is formed, and a compressed cotton having a thickness of 5 mm to 15 mm is embedded in the zenith portion, and a compressed cotton having a thickness of 2 mm to 8 mm is embedded in the peripheral portion. At this time, a water-absorbent resin is attached to the surface of the compressed cotton, or a mesh fabric is used for the cap body forming fabric in order to increase the water permeability.

[0005]

[Embodiment of the invention]

 FIG. 1 is a partially cutaway perspective view of the product of the present invention. 1 is a top fabric made of synthetic fiber fabric such as rayon, cotton or polyester, and 2 is a back fabric woven with meshes of the same fiber, which is divided into general head sizes, S, M and L. The bowl-shaped bag body 3 is sewn, and the cotton material 4 is compressed into the bag body to a thickness t of about 5 mm to 15 mm and a peripheral part b to a thickness t ′ of about 2 mm to 8 mm. And bury it.

When putting on the cap, the compressed cotton 4 is immersed in water and lightly squeezed to keep the head cold for a certain period of time. The reason why the thicknesses t and t ′ of the compressed cotton between the zenith part a and the peripheral side part b are different is that the zenith part directly receives a large amount of hot air. In order to obtain a long-term cooling effect, the thickness t is increased. However, according to the experimental results of the present inventor, the sustainability of about 2 hours under a hot sun at about 35 ° C. The above numerical range was set by conducting repeated studies to obtain.

At this time, the cotton material 4 is mixed with fibrous material, its cross-sectional shape or various other fibers, or its ratio is appropriately changed to improve the water retention rate. By spraying a water-absorbing resin from the outside or mixing a cooling agent, the above-mentioned action efficiency can be easily improved.

The inner cap body 5 configured as described above is attached to the outer surface by squeezing lightly in a state of being immersed in tap water or cold water, or shaking a few times, when seeking coolness when wearing a helmet. The helmet is put on the head with the water being lightly wiped, and then the helmet is put on. The inner cap body 5 containing water is interposed between the helmet and the helmet.

The product of the present invention, in which a mesh fabric is used as the inner backing fabric, is excellent in that water is quickly absorbed to the cotton material 4 when immersed in water. Also, when wearing a hat, it is more compatible with the head than that of a woven fabric, and is excellent in that water-cooled air containing cotton material can be efficiently transmitted to the head.

A plurality of (four in the illustrated example) through-holes 6 having an inner diameter of about 5 mm are formed at appropriate intervals near the boundary between the zenith part a and the peripheral side part b. It facilitates the smooth circulation of air inside and outside the body.

[0011]

[Effects of the Invention] The present invention is configured as described above. For the use of a helmet by a driver such as an outdoor worker or a bike under the scorching sun, the product of the present invention should be slightly immersed in water. As a result, it is possible to easily prevent a rise in the temperature at the top of the head for a relatively long period of time, and to contribute to the prevention of accidents by avoiding a feeling of illness. The product of the present invention can be manufactured at low cost, and since it is a bowl-free bowl and is flexible, when not in use, it can be folded into a pocket or the like as appropriate and conveniently carried. Excellent. It can also be used alone without a helmet, and can be used as a thermal cap in cold weather.
