 In the conventional life jacket 1 shown in FIGS. 8 to 10, the buoyancy plates 10a, 10b, ... Constituting the buoyancy member 10 are independently stacked in the bag chamber 3 as described above. Therefore, each of the buoyancy plates 10a, 10b, ... Can be freely bent in the bag chamber 3, so that the work can be easily followed internally. However, since the plurality of buoyancy plates 10a, 10b, ... Are accommodated in the bag chamber 3, friction is generated between the elastic buoyancy plates 10a, 10b ,.

In particular, since a plurality of thick buoyancy plates 10a, 10b ... Are laminated, there is a fatal drawback that the life jacket 1 becomes thicker. As the life jacket 1 becomes thicker, the bulkiness increases and the packaging container also becomes larger. Naturally, the storage volume of the packaged goods in the transportation vehicle or the warehouse also increases with the thickness. Also, since it becomes inflatable when worn, it slows down the movement of the hands and arms and reduces the range of activity. In particular, the life jacket 1 shown in FIG. 12 has a thick hem portion, so that it often interferes with the work of bending and stretching the upper body.

Further, since the buoyancy plates 10a, 10b, ... Of foamed resin are stacked in the bag chamber 3 of the main body 2, water is likely to accumulate between the buoyancy plates 10a, 10b ,. For this reason, when a passenger on a ship receives water droplets, the weight of the life jacket 1 is increased by the accumulated water. Further, there is a problem in that the life jacket 1 that has been wet becomes slow to dry, mold becomes unsanitary and becomes unsanitary, and that a cold is likely to occur and the health of the wearer may be impaired.

The present invention has been made in order to solve the above problems of the conventional life jacket, and realizes a healthy life jacket that is thin, light, easy to dry, and has high workability when worn. That is the purpose.

[0010]

[Action]

 The buoyancy material of the life jacket is divided into right and left front and back parts. The buoyancy material, which is divided at each time, is constructed by sealing air in an air chamber surrounded by a dense non-breathable polyurethane sheet. This life jacket is worn by ship passengers and port workers. When a part of the air bladder is pushed by the movement of the upper body during work, the air in the pushed portion appropriately moves in the air bladder, and the pressing portion bends freely. Also, when you wear a life jacket and enter seawater, the buoyancy of the air enclosed in the air chambers maintains a stable floating state above the sea surface.

 Embodiment 1 FIG. 1 is a front view of a life jacket according to Embodiment 1 of the present invention, FIG. 2 is a rear view of the life jacket, FIG. 3 is an inner side development view, and FIG. 4 is an outer side development view. 1 to 4, 1 is a life jacket, and 2 is a main body of the life jacket 1. Here, the main body 2 is composed of left and right front parts 2a and 2b and rear parts 2c and 2d. Reference numeral 3 is a storage chamber formed in each of the viewing zones 2a to 2d of the main body 2, 4 is a cloth covering the front and back of the main body 2, 5 is a bead, and 6 is a joint cloth.

The wrapping cloth 4 is a light and breathable water-resistant fiber, for example, a slightly thick Panama-woven yellow outer material 4a such as polyester spun 20 twin yarn and a thin polyester pocket mesh yellow. It consists of a lining 4b. The outer material 4a and the lining material 4b are cut from the same paper pattern, and the accommodating chamber 3 is formed in the sewn gap at each viewing time 2a to 2d, and is bordered by the bead 5 of the black tape. A highly stretchable gray joint cloth 6 called a power net (trade name) is used to connect the shoulder, both sides, and the back muscles.

Reference numeral 7 is a buoyancy material. The structure of the buoyancy member 7 is shown in FIGS. 5 (a) and 5 (b). As the buoyancy member 7, a thin flexible tube whose opening is closed or an outer sheet member 7a of a laminated sheet is used, and is formed in a bag shape having an air chamber 7b sealed inside. And, as shown in the figure, the gas is not enclosed in the air chamber 7b, and is formed in a long and narrow rectangular shape of 50 × 10 (mm) in length and width. As the material of the outer shell material 7a mainly composed of the buoyancy material, for example, a polyurethane film having a thickness of about 150 μm is suitable, and a maximum gas encapsulation amount of about 2000 to 2500 (cc) is used.

As shown by the broken line in FIG. 4, two buoyancy members 7 in which air is enclosed in the air chambers 7b are housed in the front viewing zones 2a and 2b on the left and right. The posterior areas 2c and 2d accommodate three pieces each. The buoyancy members 7 are stacked in the width direction while being accommodated, and the upper and lower ends of the shoulder and the hem are sewn to the lining 4b with white # 50 polyester thread. In the first embodiment, the air-filled amount of the buoyancy member 7 is 750 (cc) each, and the total filled amount is 7500 (cc).

Reference numeral 8 is a resin-made fastener, 9 is a white hem string for tightening the hem of the life jacket 1, and 11 is a hem string thread. Further, 12 is an inner pocket, 13 is a corded whistle whistle, and 14 is a retroreflective material. a is air enclosed in the buoyancy member 7.

The operation of the life jacket according to the first embodiment having such a configuration will be described below. The buoyancy material 7 is divided into four parts on the right and left front parts 2a and 2b and the rear parts 2c and 2d. The body 2 of the life jacket 1 is, for example, vertically folded in a thin four-fold thin box when delivered. It is housed compactly inside.

Prior to wearing, the foregrounds 2a and 2b are opened by the fastener 8 and put on by a passenger of a ship or a harbor worker. The body 2 draped is closed with a zipper 8 at the chest, and the hem cord 9 is tightened to wear the waistcoat. At this time, since the buoyancy member 7 is made up of a thin and flexible outer shell member 7a enclosing air a and has flexibility, each of the best seasons 2a to 2d surrounding the front, rear, left and right sides of the wearer hits and builds up. It will be worn without bloating.

When not in use or in a stationary state during wearing, the enclosed air a in the buoyancy member 7 of the main body 1 is scattered at unspecified positions in the air chamber 7b inside. When a part of the outer casing 7a is pushed from the inside as the wearer moves the upper body during work, the air a of the pushed portion appropriately moves in the air chamber 7b and the pushed portion bends freely. To do. Therefore, since the circumference is surrounded by the buoyancy member 7 having a great flexibility as described above, almost no resistance force is generated in the bending motion of the upper body due to the exercise or work.

When the body 2 of the life jacket 1 is worn and goes into the water or the sea, the buoyancy members 7 in the viewing zones 2a to 2d receive water pressure and are pressed from the outside. Therefore, the enclosed air a is pushed up from the hem side and an air tank is formed above all the outer shell members 7a. The total buoyancy of the formed air tank reaches the specified value of 7.5 kg. The buoyancy of the buoyancy member 7 keeps the wearer of the life jacket 1 floating on the water surface.

In the unlikely event of a marine accident or the like causing the wearer to float on the surface of the sea, ring the whistle whistle 13 taken out from the inner pocket 12 to inform the ship underway of the abnormality. You can In addition, at night, projection light for illumination from the aircraft or ship under search is reflected from the retroreflective material 14 in a multifaceted manner to inform the floating position of the victim who is wearing the life jacket 1 and is floating. You can also

The life jacket 1 worn by the rescued victim is unfastened by the hem strap 9, and the fastener 8 is lowered to remove the body 2 of the life jacket 1. Since the buoyancy member 7 is composed of the outer shell member 7a, the life jacket 1 that has been taken off dries quickly. Therefore, the life jacket 1 of the present invention has a low probability of catching a cold or a cold, is hygienic and can maintain health, and the life jacket 1 is used more frequently and the cost depreciation rate is higher.

Embodiment 2 (a) and (b) of FIG. 6 are configuration explanatory views of the essential parts of Embodiment 2 of the present invention. In FIG. 6, reference numeral 7c is a partition portion that partitions the air chamber 7b in the buoyancy member 7. Also in the second embodiment, a thin and high-density rectangular resin sheet is used for the outer casing 7a, and the air chamber 7b is divided into five chambers in the longitudinal direction by the partition 7c by heat fusion or the like as shown in the figure. . The air a, which is slightly smaller than the maximum volume, is enclosed in each of the five air chambers 7b.

In the second embodiment, the longitudinal direction of the buoyancy member 7 is divided into a plurality of parts by the partition 7c, so even if the air chamber 7b is filled with air a having a volume close to the maximum volume, the flexibility is maintained in the dividing direction. Can be given. Therefore, according to the second embodiment, there is a feature that resistance to flexion and extension of the upper body is reduced and that the life garment 1 that can increase the buoyancy per buoyancy member 7 can be configured.

Third Embodiment FIG. 7 is a configuration explanatory diagram of a main part of a third embodiment of the present invention. In the third embodiment, the partition 7c is made more dense than that of the second embodiment, and the air chambers 7b are formed in a grid pattern so as to intersect the vertical direction and the horizontal direction. Further, an outer shell member 7a that constitutes the buoyancy member 7 is made in conformity with the contour shape of each of the viewing zones 2a to 2d of the main body 2. Although not shown in the figure, a grid-like air chamber 7b is similarly formed in the right and left posterior regions 2c and 2d.

According to the third embodiment shown in FIG. 7, the life jacket 1 is deformed according to the movement of each part on the skeleton of the upper body. As a result, there is an advantage that it is possible to provide a life jacket 1 which is thinner, lighter and more compact than the second embodiment and which is easy to move.

In the above-mentioned embodiment, the case where the polyester film is used as the buoyancy material has been described as an example, but another synthetic fiber may be used as long as it is a flexible material that is thin and durable and can maintain airtightness for a long time. You may use a class etc. Further, although the buoyancy members are arranged in the vertical direction in Example 1, the arrangement direction may be any direction such as sideways or diagonal, and the size is not limited to 10 cm × 50 cm, and various sizes and shapes are combined. You may do so.

Further, as the enclosed gas, other gas other than air may be used as long as it has a low specific gravity and is nonflammable, and the enclosed amount should be appropriately selected according to the number of outer shell materials and the specifications of the life jacket. You can It is convenient to increase the amount of gas enclosed in the foreground side or use a gas with a low specific gravity so that it can be automatically held in a backward tilted state based on the floating posture in water or in the sea.

Further, although a life jacket made up of four seasons without sleeves is illustrated, the present invention can also be applied to a life jacket such as a front and rear split type necklace type or a sleeved jumper type. is there. Further, although the description has been given to the case where the covering cloth is the surface and the lining of the synthetic resin fiber of the mesh weave, the covering body of other fibers can be used. Furthermore, the buoyancy material may be attached by an appropriate means such as an adhesive, or may be detachable by a liner or a hook, and the presence or absence of a tie cloth or a fastener and the material and shape thereof are not necessarily limited to those in the embodiment. .

Configured the batter. In addition, a life jacket was constructed using a polyurethane sheet with a thickness of approximately 150 microns for the outer shell. In addition, a life jacket was constructed with a plurality of air chambers in the outer shell.

Further, the present invention provides a plurality of floating bag-shaped buoyant bodies having buoyancy by enclosing gas in a plurality of air chambers provided in a grid pattern inside a non-air-permeable outer shell, and a buoyant body A life jacket was constructed with a covering body consisting of front and back parts on the left and right, with both sides covered with outer and lining and the shoulders, both sides, and the spine connected by joints. In addition, a life jacket was constructed in which the contour of the outer shell material was formed in a shape similar to that of each viewing season.

As a result, the life jacket of the present invention has the following effects. (1) Since the buoyancy member is made up of an outer shell that encloses gas, the entrapped gas moves according to changes in the wearer's body, and resistance hardly occurs. Therefore, the workability is remarkably improved as compared with the conventional life jacket that uses the independent foam resin as the buoyancy material. In particular, if the amount of gas enclosed in the shell material that hits a portion where bending, stretching, and swirling is severer is smaller than in other portions, the overall buoyancy can be maintained within the specified range, and workability can be further improved.

Therefore, the packaging container is small and compact, and it is unlikely to be inflated during transportation or when it is worn without taking a storage place in the warehouse. (3) In addition, due to the above (1), there is almost no part where water accumulates inside the life jacket. Therefore, compared with the buoyancy material of the independent foamed resin, it dries faster and the efficiency of use is dramatically improved, and it also contributes to hygiene and health maintenance by not wearing wet life jackets. Become.

(4) Since the number of outer shells and air chambers forming the buoyancy member can be appropriately increased, even if a gas in the outer shell leaks, the specified buoyancy can be obtained. Can be held. (5) Further, as in the case of Example 3, by constructing a cross-shaped air chamber by matching the buoyancy material with the contour shape of each body of the body, the life jacket adapts to the movement of each part on the skeleton of the upper body. Will be transformed. Therefore, the life jacket is thin and light, and it is possible to provide a life jacket that is compact and easy to move.

Therefore, according to the present invention, it is possible to provide a healthy life jacket that is thin, light and easy to dry and has high workability when worn.
