Description

[Detailed explanation of the invention] <Industrial application field> This invention allows crew members of ships operating in cold waters to avoid dying from the cold even if they accidentally fall into the sea while working on the deck. Concerning a water-resistant and cold-proof life jacket that is worn to keep you afloat until rescue comes.

<Prior Art> In order to prevent death due to cold even if a person falls into the sea, it is necessary to cover at least the body from the neck to the waist with waterproof and cold protection material. Even if the life jacket is worn, if the degree of closeness of the neck to the human body is low, there will be a problem that water will seep into the inside of the life jacket from the neck. As disclosed in Japanese Utility Model Publication No. 1117/1987, a device that firmly attaches the neck to the human body is one in which air is supplied to the inside at a pressure higher than the external water pressure, and the pressure difference between the inside and outside is maintained approximately at a predetermined level. In a dry diving suit that is maintained at a constant value, a soft rubber membrane tube for airtight sealing at the neck extending from the main body side and terminating in the shape of a tube end is folded into the folding section where the tube end side part from the middle is folded inward. The natural shape before folding is formed into a thick part in which the entire inner circumferential surface of the folded part near the folding position bulges out.

<Problems to be solved by the invention> However, with this technology, there is a problem that the soft rubber membrane tube for airtight sealing is non-slip, so it is difficult to wear and is easily damaged. The points were also hot. In order to solve these problems, it is conceivable to attach a sliding cloth to the entire inner surface of this soft rubber membrane tube, but this would reduce the elongation of the soft rubber membrane tube, so A problem arises in that the degree of adhesion to the surface becomes low.

The purpose of this invention is to provide a water-resistant and cold-proof life jacket that is easy to wear, hard to break, and has a high degree of adhesion.

<Means for solving the problems> The means for solving each of the above problems is to construct the main body part from a waterproof and cold protection material in a shape that covers at least the human body from the neck to the waist area, and to The neck is formed into a substantially cylindrical shape, and the part from the middle of the neck to the vicinity of the opening edge of the upper end is formed into a thick folded part that is folded inward, and the inside of the neck is covered with stretchable and slippery cloth. The cloth is disposed along the upper neck, and the cloth is bonded to the upper end opening periphery of the neck and the lower end periphery of the neck, respectively.

<Function> According to the above means, the person's neck is passed through the neck of the main body from the main body side with the folded part not yet folded back, and then the folded part is folded inward to make the wearer wear it. Complete. When worn in this way, since the cloth is provided immediately inside the neck, it is easy to slip when the human body's neck is passed through the neck of the main body from the main body side, making it easy to wear. Moreover, since this fabric only connects the upper and lower ends, the elongation of the neck does not decrease, and when worn,
Since the air existing between the cloth and the neck presses the folded portion toward the neck of the human body, it is possible to improve the degree of adhesion of the neck.

<Example> This example includes an upper body part 2 and a lower body part 4 as shown in FIGS. 4 and 5. Upper body part 2
consists of a body part 6, sleeve parts 8, 8, and a neck part 10. The torso section 6 is formed in a shape to cover the human body from the shoulders to the vicinity of the waist, and the sleeve sections 8 are formed in a shape to cover both arms up to the vicinity of the wrists. The body portion 6 and the sleeve portions 8, 8 are made of a waterproof and cold-proofing material, which is made of a film or sheet material with sufficient waterproof properties and a heat insulating material adhered to the inner surface thereof. In addition, the sleeve openings 12, 12 of the sleeve parts 8, 8 are made of neoprene foam,
Constructed from a stretchy material such as latex rubber, it maintains an airtight seal when worn.

As shown in FIG. 1, the neck section 10 has a substantially cylindrical shape and is made of a stretchable material such as neoprene foam, and its lower opening edge is hermetically connected to the body section 6. From the middle of the neck portion 10 to the upper opening edge, a thick folded portion 14 is formed that bulges out over the entire area toward the center, and this folded portion 14 is shown in FIGS. 2 and 3. It is folded inward like this.

Inside the neck part 10 is a cloth 1 formed into a substantially cylindrical shape and large enough to cover the entire inner surface of the neck part 10.
The cloth 16 on which the cloth 16 is provided is made of stretchable and slippery material such as nylon knit, for example. The upper edge of the cloth 16 is fixed to the entire upper opening edge of the neck 10, and the lower edge of the cloth 16 is fixed to the lower edge of the neck 10.

A floating body 18 having a generally U-shaped planar shape is provided on the outside of a portion of the body portion 6 corresponding to the shoulder.
This buoyant body 18 has a hemispherical partition wall 2 inside.
0 is divided into two rooms 22 and 24. One 22 of these two rooms 22, 24 is
It communicates with an air chamber 28 provided on the inner surface of the back side of the body portion 6 via a check valve 26 . Further, the buoyant body 18 is mechanically coupled to the body portion 6 by the check valve 26 . Reference numerals 30 and 32 shown in FIG. 3 are air supply devices for supplying air to the chambers 22 and 24 of the buoyant body 18.

The lower body part 4 is made of the same material as the upper body part 2 and is shaped like pants and covers from the vicinity of the waist to the vicinity of the ankles. At the hem of this lower body part 4,
Sock-like parts 26, 26 that cover the feet are connected in an airtight manner. The covering portion 28 is also airtightly connected to the hem portion so as to surround the vicinity of the instep portions of the sock-like portions 26, 26. The sock-like part 26 and the covering part 28 are also manufactured from the same material as the upper body part 2.
Reference numeral 30 denotes a binding string, which is used to expel air remaining inside the lower body part 4 to the outside when the lower body part 4 is worn. 32 is a fixed band, which connects the upper body part 2 and the lower body part 4.
This is to surround and fix the area around the joint from the outside.

In the water-resistant and cold-proof life jacket constructed in this way, the first
When the upper body part 2 is worn on the human body from the state shown in the figure, since the cloth 16 is provided inside the neck part 10, the neck of the human body can be smoothly passed through the neck part 10 from the inside of the upper body part 2. After this, the folding part 14
However, after the folding, the pressure of the air existing between the cloth 16 and the neck 10 increases, and the folded part 14 of the neck 10 is folded toward the neck side of the human body as shown in FIG. Press. With this, the neck 10
is in close contact with the neck of the human body.

In the above embodiment, the upper body part 2 and the lower body part 4 are formed separately, but they may be formed integrally.

<Effects> As described above, according to this invention, the folded part of the neck is made thick, and the fabric is bonded to the upper and lower opening edges of the neck.
It is possible to realize a water-resistant and cold-proof life jacket that is easy to wear, hard to damage, and fits tightly around the neck of the human body.
