2. Description of the Related Art Life jackets for keeping a wearer afloat in water and positioning the head above the water surface are conventionally known (for example, see Patent Document 1). The life jacket disclosed in Patent Document 1 includes a torso and a lower limb cover integrally formed with the torso, and is formed into a bag shape as a whole. In this life jacket, a large amount of air is interposed in the gap between the torso and lower limb covers and the wearer's body, and the buoyancy of the air space prevents the wearer from sinking.

Utility Model Publication No. 50-23999

In the life jacket disclosed in Patent Document 1, buoyancy is obtained by interposing a large amount of air in the life jacket. However, with this life jacket, since air can move freely within the life jacket, the way the air accumulates in the life jacket may differ depending on the wearer's body shape, and there is a risk that sufficient buoyancy may not be obtained in the lower limbs. There is. Therefore, when the life jacket of Patent Document 1 is worn during a disaster such as a tsunami, there is a risk that the wearer's lower limbs may hit an underwater obstacle.

SUMMARY OF THE INVENTION The present invention has been made based on the above-mentioned problems, and its purpose is to provide a disaster-responsive life jacket that can easily avoid the danger of the wearer's lower limbs hitting underwater obstacles.

A disaster response type life jacket according to the present invention has a first buoyant body, a torso section that opens in the front and has a shape that covers a human torso, and a plurality of second buoyant bodies. , comprising: a pants-type lower leg cover configured separately from the torso and coupled to the torso; and a coupling means for coupling the torso and the lower leg cover ; The coupling means is constituted by a hook and loop fastener having a first hook and loop fastener piece provided on the torso and a second hook and loop fastener piece provided on the lower leg cover and fixable to the first hook and loop fastener piece, The second hook and loop fastener piece is fixed to the waist of the trunk by being fixed to the first hook and loop fastener, and the hook and loop fastener is capable of maintaining the front surface of the trunk in a closed state. The plurality of second buoyant bodies include an upper buoyant body disposed closer to the torso than the knee portion of the lower limb cover, and an upper buoyant body disposed on the opposite side of the knee portion to the torso side. and a lower buoyant body spaced apart from the upper buoyant body.

According to the present invention, the upper body is covered by the torso, and the lower body is covered by the leg cover. Therefore, lacerations in the wearer's torso and lower limbs and rapid loss of body temperature are suppressed. Moreover, since the torso covers the torso from the shoulders to the torso, it is difficult to fall off, and since the lower limb cover is connected to the torso or is formed integrally with the lower limb cover, the lower limb cover can be protected even by water currents such as a tsunami. This can prevent the cover from coming off. Furthermore, since the lower limb cover has the second buoyant body, the second buoyant body does not slip out from the lower limb cover. Therefore, the wearer's lower limbs are in a floating state due to the buoyancy of the second buoyant body. Therefore, in the event of a disaster such as a tsunami, the wearer's lower limbs are less likely to hit underwater obstacles, making it easier to avoid the danger of the wearer's lower limbs hitting underwater obstacles.

Further, according to the present invention , since the lower limb cover is a pants-type body formed separately from the torso, the wearer can easily wear the lower limb cover like pants. This makes it possible for anyone to quickly put it on in the few minutes it takes for the tsunami to arrive. Furthermore, since the lower limb cover is connected to the torso by the connecting means, it is possible to prevent the pants-shaped lower limb cover from coming off due to water flow such as a tsunami.

Furthermore, according to the present invention , the lower limb cover can be connected to the torso simply by attaching the second hook-and-loop fastener piece to the first hook-and-loop fastener piece, so even in an emergency such as a tsunami, the lower leg cover can be attached to the torso. It can be easily connected to the part. This makes it possible for anyone to quickly put it on in the few minutes it takes for the tsunami to arrive. Furthermore, since the hook-and-loop fastener can be wrapped around the torso like a belt, it is possible to more reliably prevent the leg cover from coming off due to water currents such as a tsunami.

Further, according to the present invention , the front part of the torso can be opened, making it easier to wear the torso. Furthermore, the wearer can close the front part of the torso using a hook-and-loop fastener for connecting the torso and the lower limb cover, which reduces the need for additional members to close the front part of the torso. In addition, the torso can be easily dressed even in an emergency such as a tsunami. This makes it possible for anyone to quickly put it on in the few minutes it takes for the tsunami to arrive.

Advantageous Effects of Invention According to the present invention, it is possible to provide a disaster response life jacket that easily avoids the risk of the wearer's lower limbs hitting obstacles in the water.

Hereinafter, each embodiment of the present invention will be described with reference to the drawings. However, for convenience of explanation, each figure referred to below is a simplified representation of the main components necessary for explaining the disaster response type life jacket according to the embodiment of the present invention. Therefore, the disaster response type life jacket according to each embodiment of the present invention may include any component not shown in each figure referred to in this specification.

(First embodiment)
The disaster response type life jacket 1 is for keeping the wearer afloat in water and positioning the head above the water surface WL in the event of a disaster such as a tsunami. As shown in FIGS. 1 and 2, the disaster response life jacket 1 includes a torso 2 having a shape that covers a person's torso, a lower limb cover 3 configured separately from the torso 2, and a lower limb cover 3. coupling means 4 coupled to the body 2.

The body portion 2 is configured in a jacket type. The torso 2 has a shape and size that covers the wearer's torso, and the torso 2 includes a sleeve portion 2b that has a shape and size that covers both arms, and a hood portion 2c that has a shape and size that covers the head. are connected. Note that the sleeve portion 2b and the hood portion 2c may be configured to be detachable from the body portion 2.

The body portion 2 has a front surface portion 2aa and a rear surface portion 2ab opposite to the front surface portion 2aa. The front part 2aa has a right front part 31 and a left front part 32, which are configured as left and right parts separately. The right end of the right front section 31 is connected to the right end of the rear surface section 2ab, and the left end of the left front section 32 is connected to the left end of the rear surface section 2ab. Thereby, the trunk portion 2 is configured to open in the front. Note that the body portion 2 does not have to be configured to open in the front. In this case, the right front section 31 and the left front section 32 are integrally constructed.

The sleeve portion 2b is connected to the shoulder portion of the torso portion 2 and is formed to cover the wearer from the shoulder position to the wrist position. The hood part 2c is connected to the upper part of the body part 2, and the front side is open. Note that the sleeve portion 2b and the hood portion 2c may be omitted.

The trunk 2 has a first buoyant body 2d. The first buoyant body 2d is configured to generate a buoyant force sufficient to float the body of the wearer wearing the torso 2 in water. For example, the first buoyancy body 2d can be made of styrofoam.

The first buoyant body 2d includes a front buoyant body 5 built in the front surface 2aa of the body 2, and a rear buoyant body 6 built in the rear surface 2ab of the body 2. The front buoyant body 5 is composed of two buoyant bodies. Specifically, the front buoyant body 5 includes a left buoyant body 5a built in the left front part 32 and a right buoyant body 5b built in the right front part 31. In addition, when the body part 2 is not configured to open in the front, the front buoyant body 5 may be configured by a single buoyant body. The rear surface buoyancy body 6 is built into the rear surface section 2ab of the trunk section 2. Note that the rear buoyant body 6 may be omitted if the body of the wearer wearing the torso 2 can be floated in water using only the front buoyant body 5.

The front buoyancy body 5 is configured to have greater buoyancy than the buoyancy of the rear buoyancy body 6. That is, the front buoyancy body 5 is configured such that the total buoyancy of the buoyancy of the left buoyancy body 5a and the buoyancy of the right buoyancy body 5b is greater than the buoyancy of the rear buoyancy body 6. As a result, when the trunk 2 floats on water, the trunk 2 floats such that the front part 2aa is located above the rear part 2ab. Therefore, the wearer can float with the front side of the wearer's body facing upwards (see FIG. 2). Note that the buoyancy of the front buoyancy body 5 may be the same as the buoyancy of the rear buoyancy body 6.

A GPS terminal 25 is built into the front surface 2aa of the body 2 (see FIGS. 1 and 2). The position of the GPS terminal 25 is not particularly limited as long as it is on the front surface 2aa of the torso 2. For example, the GPS terminal 25 may be disposed on the front side of the front buoyant body 5 in the front part 2aa of the torso 2, or may be embedded in the front buoyant body 5. Note that the GPS terminal 25 may be omitted.

The lower leg cover 3 is formed into a pants shape having a shape and dimensions that allow both legs to be placed therein. Note that the lower limb cover 3 may be configured integrally with the torso 2. That is, the upper end of the lower leg cover 3 may be connected to the lower end of the torso 2. In this case, the coupling means 4 for coupling the lower leg cover 3 to the trunk 2 is omitted.

The lower leg cover 3 includes a second buoyant body 7 and a stretchable rubber shoulder belt 8. Note that the shoulder belt 8 may be made of, for example, a textile, or may be omitted.

The second buoyant body 7 is configured to generate enough buoyancy to float the lower limbs of the wearer wearing the lower limb cover 3 in water. For example, the second buoyant body 7 can be made of styrofoam.

The second buoyant body 7 is provided on the front surface 3a of the lower limb cover 3. As a result, when the lower limb cover 3 is floated on water, the lower limb cover 3 floats with the front surface 3a facing upward. Therefore, due to the buoyancy of the lower limb cover 3 and the buoyancy of the torso 2, the wearer is able to hold the wearer in a state where the front side of the wearer's body is facing upward and the upper and lower body are bent forward in a dogleg shape. floating (see Figure 2). Note that the attachment position of the second buoyant body 7 to the lower limb cover 3 is not limited to the front surface 3a of the lower limb cover 3, and may be provided on the side surface of the lower limb cover 3, for example.

The second buoyant body 7 is removably provided on the outer side of the front surface 3a of the lower limb cover 3. Therefore, the second buoyancy body 7 can be removed from the lower limb cover 3. Any means for attaching and detaching the second buoyancy body 7 to the lower limb cover 3 may be used as long as the second buoyancy body 7 can be easily removed by the wearer underwater. For example, the second buoyancy body 7 may be configured to be detachable from the lower limb cover 3 using a hook and loop fastener, a hook, or the like, or may be configured to be placed in a pocket (not shown) of the lower limb cover 3. In this case, the second buoyant body removed from the lower limb cover 3 may be configured to be attached to the torso 2 with a hook and loop fastener, hook, or the like. Note that the second buoyant body 7 does not have to be configured to be detachable from the lower limb cover 3.

In the example of FIG. 1, a total of four second buoyant bodies 7 are provided at the upper and lower parts of the lower limb cover 3, but the lower limbs of the wearer are floating in the water due to the buoyancy of the second buoyant bodies 7. The number of second buoyant bodies 7 is not particularly limited as long as it can be done. For example, a total of two second buoyant bodies 7 may be provided between the upper and lower parts of the lower limb cover 3.

As shown in FIG. 3, the shoulder belt 8 has one end fixed to the front surface 3a of the inner surface of the lower leg cover 3, and the other end fixed to the inner rear surface 3b of the lower leg cover 3, thereby forming a loop shape. . Thereby, the shoulder belt 8 can be hung on the shoulder of the wearer. Both ends of the shoulder belt 8 are attached to positions offset downward from the upper end 9 of the lower limb cover 3. Thereby, the wearer can put the hem of the torso 2 inside the lower leg cover 3 while the shoulder belt 8 is hung on the shoulder. That is, as will be described later, although the band-shaped second surface fastener piece 4ab is attached to the upper end 9 of the lower limb cover 3, by putting the hem of the torso 2 inside the lower limb cover 3, the second surface The fastener piece 4ab can be wrapped around the trunk 2.

The coupling means 4 is constituted by a hook and loop fastener 4a having a first hook and loop fastener piece 4aa provided on the torso 2 and a second hook and loop fastener piece 4ab provided on the lower leg cover 3.

The first hook-and-loop fastener piece 4aa is formed on each of the right front section 31, the left front section 32, and the rear section 2ab of the trunk section 2. The first hook-and-loop fastener piece 4aa may be formed continuously over the entire circumference in the circumferential direction at the front right portion 31, the front left portion 32, and the rear surface portion 2ab, or may be formed intermittently in the circumferential direction. good. The outer surface of the first hook-and-loop fastener piece 4aa serves as a bonding surface. Note that two first hook-and-loop fastener pieces 4aa are provided vertically spaced apart from each other on the torso 2; There is no particular limitation as long as it does not easily come off.

The second hook-and-loop fastener piece 4ab is arranged along the upper end 9 of the lower leg cover 3. The second hook-and-loop fastener piece 4ab is formed in a band shape extending in the waist direction, and has a length approximately equal to the length of the trunk portion 2 in the circumferential direction. Therefore, the second hook-and-loop fastener piece 4ab can be wrapped around the entire circumference of the body portion 2. The second hook-and-loop fastener piece 4ab is fixed to the upper end 9 on the rear surface 3b side of the lower leg cover 3, and extends to both left and right sides from the upper end 9 on the rear surface 3b side. Both the front and rear surfaces of the second hook-and-loop fastener piece 4ab serve as bonding surfaces.

As shown in FIGS. 1 and 2, a connecting member 10 that connects the trunk 2 and the lower limb cover 3 is attached to the trunk 2 and the lower limb cover 3. The coupling member 10 includes a first coupling piece 10a with one end attached to the outside of the trunk 2, a second coupling piece 10b with one end attached to the upper part of the outer side of the lower leg cover 3, and a first coupling piece 10a and a second coupling piece 10b. It has a connecting member 10c such as a buckle that connects the two connecting pieces 10b. The first connecting piece 10a is attached above the hem of the body 2. With this, the first connecting piece 10a and the second connecting piece 10b located on the outside of the lower limb cover 3 can be connected by the connecting member 10c while the hem of the torso 2 is placed inside the lower limb cover 3. .

In the example of FIG. 1, the attachment position of the first connecting piece 10a to the body part 2 is located between the upper and lower first hook-and-loop fastener pieces 4aa; As long as the first connecting piece 10a and the second connecting piece 10b can be connected by the connecting member 10c in a state that they are inserted inside, the first connecting piece 10a and the second connecting piece 10b are not limited to the space between the upper and lower first hook-and-loop fastener pieces 4aa. Moreover, since the connecting member 10 is used auxiliary to the hook-and-loop fastener 4a to connect the lower leg cover 3 to the trunk 2, it may be omitted.

Next, a method of putting on the disaster response life jacket 1 configured as described above will be explained with reference to FIGS. 4(a) to 4(d). Note that in FIGS. 4(a) to 4(d), the first and second buoyant bodies 2d and 7 and the coupling member 10 are omitted for convenience.

First, after passing both legs through the lower limb cover 3, the shoulder belt 8 is hung over the shoulders and the lower limb cover 3 is put on. At this time, since the shoulder belt 8 expands and contracts, the shoulder belt 8 can be easily hung on the shoulder without adjusting the length.

Next, the torso 2 is put on. At this time, the torso 2 is placed over the shoulder belt 8. Specifically, first, open the front part 2aa of the torso 2 and pass both arms through the sleeve part 2b, then open the right front part 31 and the right front part 31 in the front part 2aa so that the right front part 31 is located in front of the left front part 32. and the left front portion 32 (see FIGS. 4(a) and 4(b)). In this state, the hem of the torso 2 is inserted between the lower limb cover 3 and the shoulder belt 8, and the first connecting piece 10a and the second connecting piece 10b are connected by the connecting member 10c (Figs. 2, 3, and 3). 4(c)). Note that when the connecting member 10 is omitted, the work of connecting the first connecting piece 10a and the second connecting piece 10b is omitted.

Next, the second hook-and-loop fastener piece 4ab of the hook-and-loop fastener 4a is wrapped around the trunk 2 like a belt (see FIGS. 2, 4(c) and 4(d)). Specifically, the second hook-and-loop fastener piece 4ab on the left is wound so as to extend from the left front portion 32 to the right front portion 31, and the second hook-and-loop fastener piece 4ab on the left is fixed to the first hook-and-loop fastener piece 4aa. Subsequently, the second hook-and-loop fastener piece 4ab on the right side is wound around from the right front portion 31 to the left front portion 32, and the second hook-and-loop fastener piece 4ab on the right side is fixed to the second hook-and-loop fastener piece 4ab on the left side from the outside. In addition, when the left front part 32 is overlapped so that it is located in front of the right front part 31, the second hook and loop fastener piece 4ab on the right side is fixed to the first hook and loop fastener piece 4aa, and the second hook and loop fastener piece 4ab on the left side is fixed to the first hook and loop fastener piece 4aa. is fixed to the right side second hook-and-loop fastener piece 4ab from the outside. Thereby, the lower limb cover 3 is coupled to the trunk 2, and the front surface 2aa of the trunk 2 is maintained in a closed state. Finally, the hood part 2c is put on.

In the disaster response type life jacket 1, the upper body is covered by the torso 2, and the lower body is covered by the lower limb cover 3. Therefore, lacerations around the wearer's torso, arms, head, and lower legs are suppressed, and rapid loss of body temperature is suppressed. Moreover, since the torso 2 covers the torso from the shoulders to the torso, it is difficult to take off, and since the lower leg cover 3 is connected to the torso 2, there is no possibility that the lower leg cover 3 will come off due to water currents such as a tsunami. It can be prevented. Furthermore, since the lower limb cover 3 has the second buoyant body 7, the second buoyant body 7 does not slip out from the lower limb cover 3. Therefore, the wearer's lower limbs become floating due to the buoyancy of the second buoyant body 7 (see FIG. 2). Therefore, in the event of a disaster such as a tsunami, the wearer's lower limbs are less likely to hit underwater obstacles, making it easier to avoid the danger of the wearer's lower limbs hitting underwater obstacles.

In the above-mentioned disaster response type life jacket 1, the lower limb cover 3 is in the form of pants and is configured separately from the torso 2, so that the wearer can easily wear the lower limb cover 3 like pants. This makes it possible for anyone to quickly put it on in the few minutes it takes for the tsunami to arrive. Furthermore, since the lower limb cover 3 is connected to the torso 2 by the connecting means 4, it is possible to prevent the lower limb cover 3 from coming off due to water currents such as a tsunami.

In the above-mentioned disaster response type life jacket 1, the lower limb cover 3 can be connected to the girth of the torso section 2 by simply attaching the second hook-and-loop fastener piece 4ab to the first hook-and-loop fastener piece 4aa, so that it can be used in emergencies such as tsunamis. Even if there is a lower leg cover 3, the lower limb cover 3 can be easily connected to the torso 2. This allows anyone to quickly put it on within a few minutes before the tsunami arrives. Furthermore, since the hook-and-loop fastener 4a can be wrapped around the torso 2 like a belt, it is possible to more reliably prevent the leg cover 3 from coming off due to water currents such as a tsunami.

In the disaster response type life jacket 1, the front part 2aa of the torso 2 can be opened, making it easy to wear the torso 2. Furthermore, since the wearer can close the front surface 2aa of the trunk 2 with the hook-and-loop fastener 4a that connects the trunk 2 and the lower limb cover 3, the wearer can separately install a member for closing the front surface 2aa of the trunk 2. No need to prepare. Therefore, even in an emergency such as a tsunami, the torso 2 can be easily put on, so anyone can quickly put on the clothes within a few minutes before the tsunami arrives.

In the above-mentioned disaster response type life jacket 1, the front part 2aa configured to open in the front is closed by the belt-shaped hook and loop fastener 4a, so that the torso part 2 can be closed in a state that matches the wearer's body shape. Furthermore, by using the hook-and-loop fastener 4a to connect the torso 2 and the lower leg cover 3, it is possible to realize a bonding force that can withstand the tensile force applied when caught in a tsunami, and easy attachment.

In the above-mentioned disaster response type life jacket 1, the shoulder belt 8 can be hung over the wearer's shoulders, so that the lower limb cover 3 is difficult to fall off from the wearer's lower limbs. Furthermore, since the rubber shoulder belt 8 is expandable and contractible, there is no need to adjust the length of the shoulder belt 8 using a buckle or the like to match the wearer's body shape. Therefore, even in an emergency such as a tsunami, the length of the shoulder belt 8 can be easily adjusted to suit the wearer's body shape. Therefore, anyone can quickly put it on in the few minutes it takes for the tsunami to arrive.

In the disaster response type life jacket 1, the torso 2 overlaps the shoulder belt 8, so the shoulder belt 8 will not come off while the torso 2 is worn. Therefore, the lower limb cover 3 is difficult to come off.

In the disaster response type life jacket 1, the front buoyancy body 5 disposed on the front side of the torso 2 has a larger buoyancy than the rear buoyancy body 6 disposed on the rear face 2ab of the torso 2. generates buoyancy such that the front buoyant body 5 is located above the rear buoyant body 6 in the water. For this reason, the front side of the wearer's body tends to be in a state facing upward, making it easier to keep the wearer's face above the water surface WL at all times, making it easier to avoid death by suffocation.

In the above-mentioned disaster response life jacket 1, the lower limb cover 3 generates buoyancy so that the front surface 3a faces upward in the water, so that the wearer's upper body and lower body can be It becomes easy to bend forward in a dogleg shape (see Figure 2). Therefore, in the event of a disaster such as a tsunami, the wearer's lower limbs are less likely to hit underwater obstacles.

In the disaster response type life jacket 1, the wearer can remove the second buoyant body 7 from the lower limb cover 3, so the wearer cannot remove the second buoyant body 7 from the lower limb cover 3 and walk or swim in the water. can.

In the above-mentioned disaster response type life jacket 1, the GPS terminal 25 is arranged at the front part 2aa where the front buoyancy body 5 having a larger buoyancy than the rear buoyancy body 6 arranged at the rear part 2ab of the torso 2 is arranged. Therefore, the GPS terminal 25 is easily positioned above the water surface WL at all times without being submerged in water (see FIG. 2). Therefore, even if the wearer is swept away by a tsunami, it is easy to locate the wearer.

(Second embodiment)
Next, a disaster response type life jacket according to a second embodiment will be explained. Hereinafter, elements in the second embodiment that correspond to those in the first embodiment will be given the same reference numerals as those in the first embodiment, and a description thereof will be omitted.

As shown in FIG. 5, the disaster response life jacket 11 of the second embodiment includes a torso 12, a lower limb cover 13 integrally formed with the torso 12, and an opening/closing hook-and-loop fastener 14. The overall shape resembles a sleeping bag. Therefore, the disaster response type life jacket 11 of the second embodiment is also suitable for people who cannot move, such as bedridden elderly people and sick people.

The body section 12 has a front surface section 2aa having a right front section 31 and a left front section 32, a rear surface section 2ab, a hood section 2c, and a first buoyant body 2d. The torso 12 is formed into a substantially cylindrical shape large enough to accommodate the wearer's torso and both arms. The body portion 12 is configured to open in the front. In the example shown in FIG. 5, the front surface 2aa of the trunk 2 is configured to open widely to the left and right by forming an opening 15 from the upper end to the upper end of the lower leg cover 13. Note that the opening 15 in the front surface 2aa of the torso 2 does not have to reach the position of the lower leg cover 13. Furthermore, a GPS terminal 25 may be built into the front surface portion 2aa of the body portion 2 (see FIG. 5).

The opening/closing hook-and-loop fastener 14 is for closing the opening 15 in the front part 2aa of the body part 2. The opening/closing hook-and-loop fastener 14 includes a first hook-and-loop fastener piece 14a provided on the front surface 2aa of the trunk 2, and a second hook-and-loop fastener piece 14b attached to the first hook-and-loop fastener piece 14a. have

The first opening/closing hook-and-loop fastener piece 14a is formed on each of the front right portion 31 and the front left portion 32 of the front surface portion 2aa of the body portion 2. In addition, the first opening/closing hook-and-loop fastener piece 14a may be formed so as to be continuous in the circumferential direction in each of the left front part 32 and right front part 31 of the front part 2aa, or may be formed intermittently in the circumferential direction. . Further, two first opening/closing hook-and-loop pieces 14a are provided at each of the left front section 32 and right front section 31 of the front surface section 2aa of the trunk section 2 at an interval vertically. The number of pieces 14a is not particularly limited as long as the opening 15 is prevented from being easily opened by water flow such as a tsunami.

The second opening/closing hook-and-loop fastener piece 14b has a fixed part 14ba fixed to the rear surface part 2ab of the body part 2, and a pair of sticking parts 14bb extending left and right from both ends of the fixed part 14ba in the circumferential direction. A pair of attachment parts 14bb of the second opening/closing hook-and-loop fastener piece 14b are formed in a band shape so that they can be attached to the first hook-and-loop fastener piece 14a. Both the front and rear surfaces of the pair of attachment parts 14bb serve as bonding surfaces.

Note that the sticking portions 14bb can be configured in a pair on the left and right as long as they can maintain the opening 15 of the front surface portion 2aa of the body portion 2 in a closed state while being stuck on the first opening/closing hook-and-loop fastener piece 14a. You don't have to. For example, the second opening/closing hook-and-loop fastener piece 14b may be provided only on one side of the fixing portion 14ba in the circumferential direction.

In addition, in the example of FIG. 5, two opening/closing hook and loop fasteners 14 are provided, one each at the vertically intermediate portion and the bottom end of the trunk 2, but the number of opening/closing hook and loop fasteners 14 is as follows. There is no particular limitation as long as the opening 15 of the front surface 2aa of the body 2 can be maintained in a closed state.

The lower leg cover 13 is configured in a bag shape so as to wrap both legs together. The lower leg cover 13 has a second buoyant body 7. The second buoyant body 7 is provided on the front surface 13a of the lower limb cover 13. Note that the attachment position of the second buoyancy body 7 to the lower limb cover 3 is not limited to the front surface 13a of the lower limb cover 13, and may be provided on the side surface of the lower limb cover 13, for example.

The disaster response type life jacket 11 of the second embodiment configured as described above is put on as follows.

First, the wearer opens the opening 15 of the front part 2aa of the torso 2 to the left and right, and enters the torso 12 and the lower leg cover 13 through the opening 15. In this state, the front parts 2aa of the body part 2 are stacked so that the right front part 31 is located in front of the left front part 32. Then, the two hook-and-loop fasteners 14 keep the opening 15 of the front portion 2aa closed. Specifically, the left side sticking part 14bb is wrapped around from the left front part 32 to the right front part 31, and the left side sticking part 14bb is fixed to the first opening/closing hook-and-loop fastener piece 14a. Then, the right side sticking part 14bb is fixed to this left side sticking part 14bb from the outside. Thereby, the opening 15 of the front part 2aa of the body part 2 is maintained in a closed state. In addition, when the left front part 32 is overlapped so that it is located in front of the right front part 31, the right side sticking part 14bb is fixed to the first opening/closing hook-and-loop fastener piece 14a, and the left side sticking part 14bb is fixed to the right side sticking part 14bb. It is fixed to the portion 14bb from the outside.

In the disaster response life jacket 11 of the second embodiment, the upper body is covered by the torso 12 and the lower body is covered by the leg cover 13, as in the first embodiment. Therefore, lacerations in the wearer's torso and lower limbs and rapid loss of body temperature are suppressed. Moreover, since the torso section 12 covers the torso from the shoulders to the torso, it is difficult to take off, and since the lower leg cover 13 is integrally formed with the torso section 12, the lower leg cover 13 can come off even when water currents such as a tsunami occur. This can be prevented. Furthermore, since the lower limb cover 13 has the second buoyant body 7, the second buoyant body 7 does not slip out from the lower limb cover 13. Therefore, the wearer's lower limbs become in a floating state due to the buoyancy of the second buoyant body 7. Therefore, in the event of a disaster such as a tsunami, the wearer's lower limbs are less likely to hit underwater obstacles, making it easier to avoid the danger of the wearer's lower limbs hitting underwater obstacles.

In the disaster response life jacket 11 of the second embodiment, the front part 2aa of the torso 2 is configured to open in the front, so even if the torso 12 and the lower limb cover 13 are integrated, the wearer can can be put on through the opening 15 of the torso 2.

In the disaster response type life jacket 11 of the second embodiment, the lower limb cover 13 is configured in a bag shape so as to wrap both legs together, so it has a shape that allows it to easily wrap around the wearer. Therefore, in the disaster response type life jacket 11 of the second embodiment, it is easier for a person who cannot move, such as a bedridden elderly person or a sick person, to put on the life jacket than when the lower limb cover 13 is configured in the shape of pants.

In the disaster response life jacket 11 of the second embodiment, the openings 15 on the front surface 13a of the torso 2 and the lower limb cover 13 can be kept closed by the opening/closing hook-and-loop fastener 14. Even if the portion 2aa is configured to open in the front, lacerations to the wearer's torso and lower limbs can be suppressed, and the disaster response life jacket 11 can be prevented from coming off due to water flow such as a tsunami.

In the disaster response type life jacket 11 of the second embodiment, the front part 2aa configured to open in the front is closed by the band-shaped opening/closing hook-and-loop fastener 14, so that the torso part 12 can be closed in a state that matches the wearer's body shape. can.

In the disaster response life jacket 11 of the second embodiment, the GPS terminal 25 is disposed on the front surface 2aa of the torso 2 where the front buoyant body 5 is disposed, so that the GPS terminal 25 can be kept at the water surface WL without being submerged. Easier to position at the top. Therefore, even if the wearer is swept away by a tsunami, the wearer's location can be easily determined.

(Third embodiment)
Next, a disaster response type life jacket according to a third embodiment will be described. Hereinafter, elements in the third embodiment that correspond to those in the first embodiment will be given the same reference numerals as in the first embodiment, and the description thereof will be omitted.

As shown in FIG. 6, the disaster response type life jacket 21 of the third embodiment is different from the first embodiment in that a string member 22 is provided instead of omitting the second buoyant body 7 provided on the lower limb cover 3. They are different.

The string member 22 is formed of an elongated member such as a rope. The string member 22 includes a first string piece 22a that has one end fixed to the front surface 2aa of the torso 2, a second string piece 22b that has one end fixed to the front surface 3a of the lower leg cover 3, and a first string piece 22a. It has a connecting member 23 that connects the second string piece 22b. The length of the string member 22 is such that when the first string piece 22a and the second string piece 22b are connected, the upper and lower body of the wearer wearing the torso 2 and the lower leg cover 3 can be attached to the front side. The length is set so that it can be bent into a letter shape. Note that the string member 22 is constituted by a single string member formed in a length that allows the upper and lower body of the wearer wearing the torso 2 and lower leg cover 3 to be bent in a dogleg shape toward the front side. It's okay. In this case, the connecting member 23 may be omitted.

The connecting member 23 may be any member as long as it can connect the first string piece 22a and the second string piece 22b, such as a buckle.

The disaster response type life jacket 21 of the third embodiment has the torso 2 and the lower extremity cover 3 such that the upper body and lower body of the wearer wearing the torso 2 and the lower extremity cover 3 are bent toward the front side in a dogleg shape. Since the lower limb cover 3 is provided with the string member 22 connecting the lower limb cover 3, the lower limbs of the wearer wearing the lower limb cover 3 are in a state of being lifted by the string member 22 in the water. Therefore, in the event of a disaster such as a tsunami, it is easy to avoid the risk of the wearer's lower limbs hitting underwater obstacles.

In the disaster response type life jacket 21 of the third embodiment, the GPS terminal 25 is disposed on the front surface 2aa of the torso 2 where the front buoyant body 5 is disposed, so the GPS terminal 25 can be kept at the water surface WL without being submerged. (See Figure 6). Therefore, even if the wearer is swept away by a tsunami, the wearer's location can be easily determined.

Incidentally, as shown in FIG. 6, the disaster response type life jacket 21 of the third embodiment includes a torso 2 and a pants-shaped lower limb cover 3 configured separately from the torso 2. As in the second embodiment, the entire body may be shaped like a sleeping bag, that is, the torso 12 having a cylindrical shape and the lower leg cover 13 having a bag shape may be integrally formed.
