Abstract

PROBLEM TO BE SOLVED: To provide a life vest that prevents the head of a wearer from rolling even when a large wave occurs, that supports breathing even in a state of exhaustion, and that is designed for long-term survival even in the event of stormy weather at sea and tsunamis or the like.SOLUTION: A life vest includes: a vest body 1 to be mounted on a body section of a human body and incorporating a buoyancy material; and a head-holding neck collar 10 which is joint to a neck of the vest body 1 and constituted of a posterior surface 11 for supporting a posterior surface of the head of a wearer, and a pair of right and left side surfaces 12 and 13 for supporting right and left side surfaces of the head, and which incorporates the buoyancy material. Even in the case that a person has been drifting for a long time and lost physical strength, the face surface is held directed up to allow breathing to be continued, because the posterior surface and both the right and left side surfaces of the head are held by the neck collar 10 as long as the wearer is floating in a face-up position. Further, even in the case of shipping a wave, water can be drained from an open edge of the neck collar 10 and unlike a hood prevents the water from accumulating on an inside. Accordingly, long-term survival is made possible.

Description

  The present invention relates to a life jacket. More specifically, the present invention relates to a life jacket that has a high lifesaving effect even in a situation of drifting for a long time due to a tsunami or a maritime accident.

There are Patent Documents 1 and 2 as conventional techniques related to life jackets.
In Patent Document 1, a hood 2 is attached to the upper part of a life jacket. Although the hood seems to be good for protecting the head, there is a drawback that the water that entered the hood by the waves is difficult to escape, so it will make it difficult to breathe and raise the survival rate in a tsunami or maritime accident It is not possible.

  Patent document 2 attaches what is called a back collar behind the life jacket. This back collar is a flat and soft cloth like the back collar of a sailor suit. In this back collar, it is difficult to hold the head on the water surface so that it does not sink, and if the waves are rough, the head will roll sideways, which is not practical during stormy weather. Therefore, there is a drawback that the survival rate in a tsunami or maritime accident cannot be increased.

  SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a life jacket that can breathe even if there is a big wave and the head is hard to roll and is tired, and can survive for a long time against the sea or tsunami during stormy weather. And

A life jacket according to a first aspect of the present invention comprises a body body that is attached to a body part of a human body and contains a buoyancy material, and a collar winding part that holds the head, and the collar winding part is connected to the neck of the body body. The collar winding portion includes a rear surface portion that supports the rear surface of the head and a pair of left and right side portions that support the left and right side surfaces of the head, and has a built-in buoyancy material.
The life jacket of the second invention is the life jacket according to the first invention, wherein the side edge of the rear surface part and the side edge of the pair of left and right side parts in the collar winding part are located in an inverted eight shape in front view and contact each other. The buoyancy material is characterized in that a buoyancy material is individually incorporated in each of the rear surface portion and the pair of left and right side surface portions.
A life jacket according to a third aspect of the present invention is the life jacket according to the first or second aspect, wherein the buoyancy material incorporated in the body of the waist is divided into a front body and a back body, and the buoyancy of the buoyancy material in the front body is that of the back body. It is characterized by being larger than the buoyancy of the buoyancy material.
The life jacket of a fourth invention is characterized in that, in the first, second or third invention, the jacket main body and the collar winding portion are made of a flame-resistant material.

According to the first invention, even if a person drifts for a long time and loses physical strength, as long as the person floats on the chin, the head is held by the collar winding part on both the back and the left and right sides, so the face faces up Can hold and continue breathing. In addition, even if a large wave is applied, water can be drained from the open edge of the collar winding portion and can not be stored inside like a hood, so breathing can be continued from this point. Therefore, a high lifesaving effect can be obtained even in situations where drifting for a long time.
According to the second aspect of the present invention, since the buoyant material is contained in the rear surface and the left and right side portions of the collar winding portion, when the left and right side portions rise by receiving the buoyancy of water, the side edges of the inverted eight-letter shape Since it can be folded so that the side of the person's head is wrapped, it is easy to hold the head so that it does not roll from side to side. For this reason, it is easy to prevent the mouth from being soaked in water and becoming difficult to breathe.
According to the third invention, since the buoyancy of the front body is larger than the buoyancy of the back body, even if the human body is turned sideways or prone by the waves, it can be immediately returned to the back, so that it is easy to continue breathing. In addition, the left and right side portions of the collar winding portion can be easily raised. For this reason, a lifesaving effect becomes high.
According to the fourth invention, since the life jacket itself has flame resistance, it can also serve to protect the human body from a fire in the event of a fire or a general fire accompanying a tsunami or earthquake.

It is a front view of the life jacket which concerns on one Embodiment of this invention. It is a rear view of the life jacket of FIG. It is a front view of a collar winding part. It is explanatory drawing of the state which the person mounted | worn with the life jacket of this invention. It is explanatory drawing of the state which the person wears the life jacket of this invention and is drifting.

Next, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the life jacket A according to the present embodiment is composed of a jacket main body 1 to be worn on a human torso and a collar winding portion 10 for holding the head.
First, the jacket main body 1 will be described, which is not fundamentally different from the main body of a conventional life jacket.

  In the illustrated jacket body 1, the left and right front bodies 2, 3 and the back body 4 are connected by left and right shoulder parts 5, 5 and also by side parts 6, 6. The left and right front bodies 2 and 3 can be connected to each other by a fastener 7 and a plurality of belts 8 attached to the left and right side portions 6 and 6 (reference numeral 8a when three belts are shown individually). , 8b, and 8c) are coupled in front of the front bodies 2 and 3, the clothing body 1 can be securely attached to the human torso. In addition, the buckle of the belt 8 uses a known quick-type metal fitting (a plastic coupler that is hooked when inserted).

The life jacket A as a whole is made by sewing two cloth materials on the front and back sides and inserting a buoyancy material into the inside to give the life jacket the necessary buoyancy. In particular, separate buoyancy materials are built in the left and right front bodies 2 and 3 and the back body 4.
A reflective material 9 is affixed to the shoulder portions 5 and 5. In addition, you may affix the reflective material 9 in another suitable place.
In addition, the structure of illustration is an illustration, Comprising: You may use the jacket main body of what shape in this invention.

Next, features of the present invention will be described.
The life jacket A of the present invention is characterized by the configuration of the collar winding portion 10.
As shown in FIG. 1, the collar winding portion 10 is connected to the neck 1 n of the jacket main body 1 and attached. As shown in FIG. 3, the collar winding portion 10 includes a rear surface portion 11 that supports the rear surface of the head, and a pair of left and right side portions 12 and 13 that support the left and right side surfaces of the head. The rear surface portion 11 and the side surface portions 12 and 13 are made by sewing two front and back cloth materials.

The overall shape of the collar winding portion 10 is a shape obtained by removing a portion through which the neck passes from a horizontally long ellipse.
The rear surface portion 11 has a substantially trapezoidal shape, that is, a trapezoid inverted up and down with a long top edge and a short bottom edge. 11a is an arcuate long top edge, 11b is a bottom edge, 11c is a left edge, and 11d is a right edge.
The left side surface portion 12 includes an arcuate long top edge 12a, a bottom edge 12b, and a side edge 12c. The right side surface portion 13 includes an arcuate long top edge 13a, a bottom edge 13b, and a side edge 13d. Note that this is an example of the shape, and the present invention is not limited to this, and various shapes such as a long square can be used.

Each bottom edge 11b, 12b, 13b is a part connected to the neck circumference 1n of the jacket main body 1. Although the sewing line passes between the side edge 11c of the rear surface part 11 and the side edge 12c of the left side surface part 12, the same cloth material is continuous. Further, a sewing line passes between the left edge 11d of the rear surface portion 11 and the side edge 13d of the right surface portion, but the same cloth material is continuous. This sewing line may be a length connecting the bottom edges 11b, 12b, 13b and the top edges 11a, 12a, 13a, or may be a length connecting a shorter part.
The left side edges 11c and 12c and the right side edges 11d and 13d are located in contact with each other in an inverted octagonal shape opened upward in a front view (FIG. 3).

  Separate buoyancy members 20 are built in the three sections of the collar winding portion 10, that is, the rear surface portion 11 and the left and right side surface portions 12 and 13, respectively. For this reason, when immersed in water, the bottom edges 11b, 12b, and 13b are fixed to the jacket body 1, but the top edges 11a, 12a, and 13a (that is, the outer edges) can move only upward due to buoyancy. At this time, the left side edge 11c, 12c and the right side edge 11d, 13d move without being separated from each other and are in an inverted eight-letter shape. Stand up to wrap around the side of the head or face. Of course, the rear surface of the head is supported by the rear surface portion 11.

Since the buoyancy of the body 1 is a rescue application, it is preferably in the range of 5 to 10 kg for adults and 3 to 6 kg for children, but a life jacket having an arbitrary buoyancy within these ranges may be used.
The buoyancy ratio before and after the waistcoat is characterized in that the front bodies 2 and 3 are higher than the back body 4, and preferably the front body: back body buoyancy ratio is about 1.2: 1 to 2: 1. Has been. Particularly preferred is around 1.5 to 1 (for example, 60 to 65%: 40 to 35%). If the buoyancy of the front bodies 2 and 3 is large at a ratio within this range, it will be easier to hold the person face-up in the water, and even if the person is lying on the wave, it can be returned to the face-up position and breathing can be continued. Because. In addition, since the ratio of buoyancy is not extremely large, an artificial sideways movement is possible, and an autonomous movement necessary for lifesaving is also possible, such as a movement underwater.

It is preferable that all the constituent materials of the life jacket A of the present invention have flame resistance.
The life jacket A of the present embodiment is made by sewing a cloth material having heat resistance, fire resistance, and flame resistance.
If it has flame resistance, damage such as burns can be reduced by wearing the life jacket A not only in the case of a tsunami or maritime accident but also in the event of a fire accident in a building. As the flame resistant material of the cloth material, a known material can be used without particular limitation. For example, a cloth using a known flame resistant fiber (trade name “LASTAN” manufactured by Asahi Kasei Corporation) is suitable.
As the flame resistant material of the belt 8, a known material can be used. Specifically, the belt part and the buckle are preferably prepared using a known heat-resistant resin (for example, one using a polyether resin or a polyimide resin).

Below, the usage method of the life jacket A of this invention is demonstrated.
The life jacket A is worn in the same manner as a normal one. As shown in FIG. The arm is extended from above the side portions 6 and 6, and the neck is extended from around the neck (between the bottom edges 11b, 12b and 13b of the collar winding portion 10). The collar winding part 10 protrudes behind the jacket main body 1 or is slightly downward. However, because it contains buoyancy material, it does not hang down just like cloth.

  When used underwater or in the sea, as shown in FIG. 5, the human body is slightly inclined or the face can be turned up. When the wearer of the life jacket A stretches his legs and approaches the horizontal, the entire body of the wearer becomes close to the horizontal, and when the legs are directed downward, the entire body also stands. And in any state, the human body is naturally held against the chin. This is because the buoyancy of the front bodies 2 and 3 is large in the life jacket A of the present invention.

As mentioned above, the buoyancy of the front body 2 and 3 is larger than the buoyancy of the back body 4, so that even if the human body turns sideways or prone by the waves, it can be quickly returned to the back, making it easy to keep breathing Become. In addition, the left and right side portions 12 and 13 of the collar winding portion 10 can be easily raised. For this reason, a lifesaving effect becomes high. However, an autonomous operation such as artificially facing sideways or swimming is also possible.
Independent buoyancy material is contained in the rear surface of the collar winding portion 10 and the left and right side portions 12 and 13, and when the left and right side portions 12 and 13 stand up due to the buoyancy of water, the side edges of the inverted eight-letter shape It can be folded so that it covers the side of the person's head. For this reason, since it becomes easy to hold | maintain so that a head does not roll right and left, it is easy to prevent that a mouth is immersed in water and it becomes difficult to breathe even if it is touched by a big wave during a tsunami or a maritime accident.

  When the life jacket A of the present invention is worn, even if a person drifts for a long time and loses physical strength, the head and the left and right sides of the head are held by the collar winding portion 10 as long as the head floats. So you can hold your face up and keep breathing. Further, even if a large wave is applied, water can be drained from the open edge of the collar winding portion 10 and can not be stored inside like a hood, so breathing can be continued from this point. Therefore, a high lifesaving effect can be obtained even in situations where drifting for a long time.

  In addition, if the life jacket A of the present invention is made of a flame resistant material, it can also serve to protect the human body from fire in the event of a fire or general fire associated with a tsunami or earthquake.
