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 the body below the neck with waterproof and cold protection material. An example of such a diving suit is a dry diving suit as disclosed in Japanese Utility Model Publication No. 58-1117.

<Problems that the invention aims to solve> However, since the upper and lower body parts of this dry diving suit are integrally formed, there are problems in that it is difficult to wear, and if only the upper or lower body part is damaged. There is a problem that the entire system becomes unusable. In order to solve these problems, the upper body part and the lower body part may be formed separately. However, in this case, if the upper body part and the lower body part are not watertightly connected, water may enter through the joint, resulting in a fatal accident.

The purpose of this invention is to provide a waterproof and cold-proof life jacket that can watertightly connect an upper body part and a lower body part.

<Means for solving the problem> A means for solving the above problem is to form an upper body part made of waterproof and cold protection material in a shape that covers the human body from the neck area to the waist area, and a a lower body part formed of a waterproof and cold-proofing material in the shape of pants that covers from the to the feet; a clamping band made of an elastic material and having an inverted V-shaped vertical cross section and provided at the periphery of the lower end of the upper body part;
A cylindrical body made of an elastic material is provided at the periphery of the upper end of the lower body so as to penetrate into the clasp band, and the cylindrical body has a hollow portion extending over the entire periphery of the upper end of the cylindrical body. , and a fixing band made of waterproof material provided around the outer periphery of the clamping band.

<Operation> In the above method, first, the upper body part and the lower body part are worn respectively. Then, the clamped band is inserted into the clamped band, and the clamped band and the clamped band are pressed and fixed near the waist of the human body by the fixing band.

<Example> This example consists of an upper body part 2 and a lower body part 4, as shown in FIGS. 4 and 5. Upper body part 2
covers the human body from the neck to the waist,
It consists of a body part 6, sleeve parts 8, 8, and a neck part 10.
The body portion 6 and the sleeve portions 8, 8 are made of a waterproof and cold-proofing material that is made of a film or sheet material with sufficient waterproof properties and a heat insulating layer attached to the inner surface thereof. In addition, the neck portion 10 is made of a material having elasticity and watertightness.
For example, it is made of neoprene foam. Sleeve part 8,
The sleeve openings 12, 12 of 8 are similarly made of neoprene foam. A buoyant body 14 having a generally U-shaped planar shape is provided in the body portion 6 around the neck portion 10 . The interior of this buoyant body 14 is divided into two chambers 18 and 20 by a partition wall 16. 22 and 24 shown in FIG. 4 are gas supply devices;
20, respectively. Further, the chamber 18 communicates with an air chamber 28 provided on the back side of the body portion 6 via a check valve 26. Further, the check valve 26 mechanically couples the buoyancy body 14 to the body portion 6.

A clamping band 30 is provided on the peripheral edge of the lower end of the body section 6, as shown in FIG. Clamping band 30
has a cylindrical body 32 watertightly provided along the peripheral edge of the lower end of the body part 6. Further, on the outside of this cylindrical body 32, there is also a cylindrical body 34 provided watertightly along the peripheral edge of the lower end of the body portion 6. That is, the holding body 30 has an inverted V-shaped longitudinal cross-sectional shape. The cylindrical bodies 32 and 34 are made of a stretchable and watertight material, such as neoprene foam.

The lower body portion 4 has a pants-like portion 36 formed to cover from the waist region to the ankle region. Further, sock-like parts 38, 38 are connected to the hem of the pants-like part 36 in a watertight manner, respectively. Further, a cylindrical covering 40 is watertightly connected to the hem portion so as to cover the vicinity of the upper portions of the sock-like portions 38, 38. The pants-like portion 36 and the sock-like portion 38 are made of a waterproof and cold-protecting material.
The cover 40 is made of waterproof material. 4
2 is a bondage string, when wearing the pants-like part 36,
These are for discharging the air remaining inside to the outside, and are provided near both knees of the pants-shaped portion 36.

A clamped band 44 is provided along the upper edge of the pants-shaped portion 36 . This clamped band 44 is formed in a cylindrical shape, and has a tubular hollow part 46 containing air inside at the upper peripheral edge thereof, as shown in FIG. This clamped band 44
They are also made of stretchable and watertight materials, such as neoprene foam.

This clamped body 44 has entered between the cylindrical bodies 32 and 34 of the clamped body 30, as shown in FIG.
The clamping band 3 that clamps the clamped belt 44 in this way
A fixing band 48 formed in a band shape is provided on the outside of 0 so as to contact and surround it. The fixing band 46 is also made of stretchable and watertight material, such as neoprene foam.

The water-resistant and cold-proof life jacket constructed in this way is worn, for example, in the following manner. First, the upper body part 2 and the lower body part 4 are put on, respectively. Then, the held object 44 is held between the cylindrical bodies 32 and 34 of the holding body 30.
Finally, the clamping body 3 is attached to the waist of the human body using the fixing band 48.
0 and the object to be held 48 are firmly fixed.

Although neoprene foam was used in the above embodiment, other materials such as latex rubber may also be used.

<Effects> As described above, according to this invention, the clamped band is sandwiched within the clamping band, the clamping band is pressed by the fixed band, and the hollow part provided in the clamped band plays the role of packing. Therefore, the upper body part and the lower body part can be connected watertightly. In addition, it can be made watertight by simply wearing the upper and lower body parts, sandwiching the clamped band within the clamping band, and tightening it with a fixing band, so it can be easily worn in a watertight state even in an emergency such as a shipwreck. I can do it. Furthermore, the hollow part is
Since it is used as packing, it already has gas inside, so there is no need to bother to provide a gas source to flow into the hollow part.
The configuration can be simplified. Furthermore, there is no risk of damage to the watertight structure caused by filling too much gas into the hollow part. Since both the clamping band and the clamping band have elasticity, they do not shift even when moved. Moreover, since the waist is surrounded three times by the clamping band and the clamping band, it is possible to prevent the intestinal temperature, which is very important in maintaining the human body's body temperature, from dropping.
