Description

  The present invention relates to life-saving clothing, and more particularly, to life-saving clothing that has sufficient buoyancy at the time of landing and is easy to escape from the water by itself or by other forces, and has excellent usability.

  In general, various life-saving garments are used in order to save a life in the case of falling into the water or to ensure the safety of underwater work.

  For example, a life jacket has been proposed in which a wearer is put out from the shoulder to the water when the water falls and the face is held in an upright posture (for example, see Patent Document 1).

Japanese Patent Application Laid-Open No. 07-023696

  However, in the conventional life jacket described in Patent Document 1, since the wearer is lifted only by the buoyancy of the buoyancy member attached to the life jacket, the wearer is taken out from the shoulder above the water, Moreover, in order to keep the face in the upward elevation posture, it is necessary to attach the buoyancy member to the life jacket with a special configuration. Further, in the conventional life jacket, since the buoyancy member is stored inside the bag-like portion between the front and back fabrics, water penetrates inside the bag-like portion during falling water, and the wearer When escaped by self or other force, there is a disadvantage that the weight of the large amount of water entering the inside of the bag-like portion obstructs the escape and the escape operation cannot be executed at an early stage. In addition, a large amount of water entering the inside of the bag-like part remains in the bag-like part even after the life-saving clothing is removed from the water, so it takes a long time to dry the life-saving clothing or reuse it. It has become a factor that makes it difficult to use such as a long time.

  The present invention has been made in view of these points, and provides lifesaving clothing that has sufficient buoyancy at the time of landing and is easy to escape from the water by itself or by other forces, and has excellent usability. For the purpose.

  The present inventors have earnestly studied and can obtain sufficient buoyancy by positively using the air existing in the buoyancy chamber in addition to the buoyancy member provided in the buoyancy chamber as the buoyancy of the life-saving clothing, Furthermore, the present invention has been completed by discovering that it does not interfere with the escape operation from the water by providing a through hole for discharging water that has entered the buoyancy chamber.

  In order to solve the above-described problem, the life-saving clothing according to the first aspect of the present invention is a life-saving clothing including a buoyancy chamber that generates buoyancy when landing, and the buoyancy chamber It has airtightness for storing air in the upper part of the life-saving clothing, has a through-hole that can discharge water in the room to the outside when it is lifted from the water, and has a buoyancy member in the room. To do.

  Thus, since the life-saving clothing of the present invention is configured, when the buoyancy chamber is surrounded by water at the time of landing, the air present in the air-tight buoyancy chamber moves to the upper portion of the life-saving clothing. The buoyancy in the direction that lifts the wearer's head is added and the buoyancy of the buoyancy member acts at the same time, and the wearer's head is lifted above the water surface to ensure the wearer's safety. can do. Furthermore, when the wearer performs an escape operation by himself or other force from the water, the water in the buoyancy chamber can be easily discharged from the through hole provided in the buoyancy chamber to prevent it from interfering with the escape operation. Thus, the wearer can easily escape. Furthermore, since the water is drained immediately when the life-saving clothing is taken out of the water, the time required for the life-jacket to be immediately dried and reused can be shortened.

  The life-saving clothing according to the second aspect of the present invention is characterized in that the buoyancy chamber is divided into a plurality of portions of the life-saving clothing.

  Thus, since the life-saving clothing of the present invention is configured, it is possible to provide life buoyancy of an appropriate size according to each part of the wearer's body and to ensure life safety.

  The life-saving clothing according to the third aspect of the present invention is characterized in that the buoyancy member is formed of a foamed resin member having the same size as the interior of the buoyancy chamber.

  Thus, since the life-saving clothing of the present invention is configured, when a foamed resin member having the same size as the interior of the buoyancy chamber is used, the fit to the wearer's body is improved.

  Since the present invention is formed in this way, it has sufficient buoyancy at the time of landing, and it is easy to escape from the water by itself or by other forces, and exhibits the advantages such as excellent usability.

The rear trunk portion 3 is provided with a total of two buoyancy chambers 3a that are divided into left and right portions that are long in the vertical direction and one long buoyancy chamber 3a on the side of the lowermost portion. Both side portions 9 (see hatched portions) between the front body portion 2 and the rear body portion 3 are formed of a stretchable fabric material. In the present embodiment, the upper ends of the side portions 9 extend to the collar 6 beyond the shoulders. The shoulder portion is provided with a buoyancy chamber that is about the size of a shoulder pad and is continuous with both sleeves 4 and 5. The right sleeve 4 and the left sleeve 5 are each provided with a total of two buoyancy chambers 4a and 5a that are long in the length direction of the two arms positioned at the upper and lower portions of the arm, respectively. The connecting portions 10 and 11 (refer to the horizontal thin dotted lines) arranged in the inner and outer portions of the elbow corresponding to the two buoyancy chambers 4a and 5a of the right sleeve 4 and the left sleeve 5 are respectively stretchable fabric materials. Is formed by. The collar 6 and the hood 7 are also divided into a plurality of buoyancy chambers 6a and 7a, respectively. As representatively shown in FIG. 5, these buoyancy chambers 2a, 3a, 4a, 5a, 6a, and 7a are sewn in a bag shape with a front material 12 and a back material 13 made of a cloth material having airtightness in principle. It is formed by doing. As the cloth material having airtightness, a known material that is commercially available may be used. Further, in the bag-like buoyancy chambers 2a, 3a, 4a, 5a, 6a, and 7a, buoyancy members 14 (see broken lines in FIGS. 2 to 4) made of a foamed resin plate having the same size as the interior of each bag are provided. Has been. The buoyancy member 14 is preferably flexible so that it can be deformed with the movement of the wearer's body. For example, a plurality of thin plate-like materials are laminated, or foamed resin fibers are meshed. It is good to form in the same magnitude | size and shape as a buoyancy chamber, or to pack and form a plurality of foam resin masses so that it may be filled in the buoyancy chamber. And in this embodiment, the lower part (refer the mesh part in FIG.1, FIG.2, FIG.4) of the back material 13 of the buoyancy chamber 2a, 3a, 4a, 5a which faces a wearer's body up-down direction is mesh-shaped. As a material, a through hole 15 is formed that can discharge water that has entered the buoyancy chambers 2a, 3a, 4a, and 5a. Thereby, it has airtightness which stores air in the upper part of the life-saving clothing 1 in the buoyancy chambers 2a, 3a, 4a and 5a at the time of landing, and the buoyancy chambers 2a, 3a, 4a and 5a Buoyancy chambers 2a, 3a, 4a and 5a having through holes 15 through which water can be discharged to the outside are formed. About each buoyancy chamber 6a, 7a of the collar part 6 and the food | hood part 7, the back material of a location is made into the mesh-shaped material suitably. In addition, it is good to change suitably the part which arrange | positions a mesh-shaped raw material as needed. Both sleeves 4 and 5 are provided with sleeve fasteners 16 that allow a predetermined length to be opened and closed from the cuffs for the convenience of taking in and out the hands. Further, one end of each of the lower fixing belts 17a and 17b is fixed to the inner lower portion of the rear trunk portion 3 and the front same portion 2, and a male chuck 18a attached to the other end portion of the lower fixing belts 17a and 17b. And the female chuck 18b are formed so as to be connected and disconnected from each other. By fixing the lower fixing belts 17a and 17b through the wearer's crotch, the life-saving clothing 1 is prevented from leaving the wearer's body. When the lower fixing belt 17a is not in use, it is preferable that the male hook 19a fixed in the middle is fixed to the female hook 19b fixed to the inner surface of the rear trunk 3 and stored.

  Next, the operation of this embodiment will be described.

  The wearer puts both hands through the sleeves 4 and 5 and wears the front body portion 2 and the rear body portion 3, and then connects the chucks 18a and 18b through the lower fixing belts 17a and 17b through the crotch. In addition, the life-saving clothing 1 is worn by closing both the halves 8a and 8b of the body fastener 8. The sleeve fastener 16 may be closed as necessary.

  Since the buoyancy member 14 equivalent to the buoyancy chamber is housed in each of the buoyancy chambers 2a and 3a divided and arranged in a plurality of portions of the front torso 2 and the back torso 3, a feeling of fitting to the wearer's body torso Will be excellent. Similarly, since the buoyancy member 14 equivalent to the buoyancy chamber is housed in the buoyancy chambers 4a and 5a arranged in two parts in the sleeves 4 and 5, the fit to the arm is excellent. Furthermore, each side part 9 and the connection parts 10 and 11 which are formed of the stretchable fabric material can further enhance the fit, and can easily support the wearer's trunk and both arms. Thereby, the motor functionality of the life-saving clothing 1 on land or underwater can be further enhanced. Further, for protection against the cold and rain, it is possible to sufficiently protect against the cold and rain by raising the collar 6 or wearing the hood 7. Further, since the collar 6 and the hood 7 are also provided with buoyancy chambers 6a and 7a that are divided into a plurality of parts, the fit is also excellent.

  Next, a case where water is dropped or water is applied while the life-saving clothing 1 is worn will be described.

  When the water reaches the water, water enters between the wearer and the life-saving clothing 1 from the hem portions of the body portions 2 and 3 of the life-saving clothing 1. First, the life-saving clothing 1 receives the buoyancy of water and tries to leave the body of the landing person, but the lower fixing belts 17a and 17b effectively prevent it. Subsequently, water penetrates mainly into the buoyancy chambers 2 a, 3 a, 4 a, and 5 a through the respective through holes 15. At this time, since the buoyancy chambers 2a, 3a, 4a and 5a are airtight, the air originally present in the buoyancy chambers 2a, 3a, 4a and 5a moves to the upper part of the life-saving clothing 1. The buoyancy in the direction of reliably lifting the wearer's head is imparted by lifting the upper part of the wearer's torso and arms by buoyancy, and at the same time acts synergistically with the buoyancy possessed by the buoyancy member 14. Thus, the wearer's head can be lifted above the water surface to ensure the wearer's safety. Furthermore, since the buoyancy chambers 2a, 3a, 4a, 5a, 6a, and 7a are divided into a plurality of parts throughout the life-saving clothing 1, buoyancy of an appropriate size according to each part of the wearer's body can be obtained. It is generated and life safety can be ensured. Furthermore, since the side portions 9 and the connecting portions 10 and 11 are made of a stretchable fabric material and the exercise functionality of the life-saving clothing 1 is kept high even in water, the wearer needs the torso and both arms. Accordingly, it is possible to easily move the body and to change the posture easily, and it is possible to easily execute an operation for improving the safety of life. Furthermore, when the wearer performs an escape operation by himself or other force from the water, the water in the buoyancy chambers 2a, 3a, 4a and 5a is drained from the through holes 15 provided in the buoyancy chambers 2a, 3a, 4a and 5a. Since it can be easily discharged, the weight of a large amount of water can be prevented from interfering with the escape operation, and the wearer can easily escape. Further, when the life-saving clothing 1 is taken out of the water, the water is immediately drained, so that it is possible to quickly dry the life-jacket 1 and to shorten the time until it is reused.

  In addition, this invention is not limited to the said embodiment, It can change as needed.
