Description

  The present invention is a pendant life-saving device that ensures breathing by floating the mouth-nose face on the water surface when the wearer unexpectedly falls into water such as a moat, pond, lake, river, sea, or is caught in a tsunami It is about.

  In the past, in the leisure in water areas such as camping, fishing, walks, water play, etc., the actual situation is that there is no end to unexpected water accidents despite sufficient preparation and attention. In Japan, which is an island country, tsunami is a natural disaster that must always be wary.

  If you suddenly fall into water such as a river or the sea with your clothes on, you can't respond appropriately, not only infants and people who can't swim, but even those who are good at swimming everyday They often drown and are often sacrificed by water accidents.

  In order to prevent the occurrence of such a drought accident, when it suddenly falls into the water, it will automatically operate regardless of the wearer's conscious movement, and at least the mouth and nose may float on the water surface to ensure breathing. A lifesaving device that can be used is desired.

  Therefore, there is a life-saving device of a type that generates a buoyancy by automatically operating in water or operating a lever or the like to open a hole in a compressed gas cylinder with a shooting needle and injecting the compressed gas filled in the compressed gas cylinder into a floating bag. For example, a belt-type life preserver (see Patent Document 1), a waist pouch-type life preserver (see Patent Document 2), or a life jacket worn around the neck (see Patent Document 3) is known. .

  However, the life-saving device described in Patent Document 1 is intended to prevent drowning during swimming, and the floating bag is attached to the trunk in a floating ring shape and requires a great deal of buoyancy. Therefore, it is unsuitable to always wear it in preparation for unexpected submersion, including the container for compressed gas, and the waist pouch type life preserver described in Patent Document 2 is also a floating life preserver. It is a form that gives buoyancy to the human body when it is worn on the waist and requires large buoyancy, so it has a large capacity including a cylinder and is not practical.

  On the other hand, the life jacket of the neck type described in Patent Document 3 is a type that is worn on the neck and ensures respiration as shown in FIG. However, since the automatic gas filling device is integrated with the float bag to form a lifesaving device, there is a possibility that sufficient buoyancy cannot be obtained because the size of the compressed gas cylinder is limited when aiming for downsizing, and It is to be worn directly around the neck and must be fastened to the extent that it cannot be removed from the neck. The neck is tight and is simply worn like a muffler. There is a problem that the appearance is uncomfortable, especially when the winter is excluded.

  Further, in the conventional lifesaving device, for example, a plate-like sealing member provided in the compressed gas cylinder when the string or button is operated as a means for releasing the sealed compressed gas cylinder and ejecting the compressed gas in the compressed gas cylinder by the firing needle. There is known a means for making a hole (see Patent Document 4), but such a means is extremely effective for preventing malfunctions at all times, but the mechanism is complicated and parts such as using a firing needle are required. There is a danger of damaging the body, which not only causes safety problems, but also raises certainty of operation in an emergency.

  The present invention has been made in order to solve the problems of the life-saving device of the type that uses the buoyancy generated by filling the floating bag that is attached to the body with compressed gas in the water, and has a simple configuration. It is small, light and easy to wear, and can be worn regardless of the season or time, etc. However, thanks to the fact that I always wear it everyday, it automatically operates and the floating bag expands at least under the chin of the wearer, and the oro-facial surface floats on the water surface to ensure breathing. An object is to provide a pendant life preserver.

  The present invention for solving the above problems is a pendant life preserver having a pendant part and a neck string part provided with a floating bag, the pendant part protruding from the compressed gas tank, a compressed gas tank filled with compressed gas, and And a vent pipe through which the compressed gas in the compressed gas tank can be ejected from a blow-out opening provided at the distal end, and the vent pipe has a sealing means at an opening portion of a float bag provided in the neck string portion. The sealing means seals the ejection of the compressed gas in a normal state, and when the wearer falls into the water, the sealing is released and the compressed gas in the compressed gas tank passes through the passage. By blowing out into the connected floating bag through the trachea, the floating bag expands and exhibits at least the buoyancy that floats the wearer's face on the water surface, ensuring the wearer's breathing and causing a drought accident Characterized in that it stop.

  Further, in the present invention, the vent pipe is connected by being inserted so that a blowout port formed on a side surface of the vent pipe is covered with the opening of the floating bag, and the sealing means is provided on the outer periphery of the opening of the floating bag. A water-disintegratable sealing band that winds a portion where the outlet of the vent pipe is located to prevent the compressed gas from being ejected, and the sealing band seals the ejection of the compressed gas in a normal state. When the wearer falls into the water, the sealing band is released by the water, the sealing is released, and the compressed gas filled in the compressed gas tank is ejected to the floating bag, so that the number of parts is reduced. Thus, the compressed gas in the compressed gas tank can be reliably ejected to the floating bag.

  In the present invention, the term “water decomposability” refers to the property of being resistant to wetness in the air but being strong but soluble in water, the property of decreasing strength due to water wetting, or the property of being decomposed by a chemical reaction with water. When the wearer falls into the water, the wearer immediately exhibits its water-decomposable function and releases the anti-winding. The specific properties of water-decomposability are described above. It is not limited to properties (the same applies below).

  Further, in the present invention, a flange for preventing the opening of the floating bag from protruding out from the outlet at the distal end of the vent pipe protrudes, and the open end of the opening having elasticity is the vent pipe By being connected in a state of overcoming the flange, it is possible to easily connect to the vent pipe so as not to remove the floating bag.

  Still further, in the present invention, the vent pipe has a bifurcated tip projecting from the tip portion having the outlet and the flange, respectively, and is positioned on the left and right jaws of the wearer when the neck string portion is inflated. The front end of the floater is high on the front side of the wearer and the back side is low because the tip part is fitted and connected to each opening of the float bag on both sides provided in the part. It is ideal as a posture to wait for rescue because the face naturally floats in the water, and even if the wearer faints, the face floats from the surface of the water and breathing can be secured.

  Further, the neck string portion is held in a single thin string shape by a water-disintegratable member in a state where the floating bag is deflated, and when the wearer falls into water, the water-disintegratable member is released and the holding is released. In normal times, the floating bag is in the form of a thin string, so it does not interfere with the wearer. If the floating bag is wrapped in a thin string with a water-degradable decorative band, it can be decorated as a neck string part of the pendant. Can have sex.

In the present invention, by having the pendant part and body cord portion wound around the waist of the neck strap portion and respectively connected to has been wearer located on the back of the wearer, when the wearer is dropped into water It is also possible to prevent the pendant part from moving to the back side of the wearer due to the impact of the pendulum, the pendant type life preserver to be detached from the wearer, and the displacement of the float bag in the left-right direction when the float bag is inflated.

  According to the present invention, as in the case of a life preserver of the type that ensures breathing by using buoyancy generated by filling a floating bag attached to the body with compressed gas in the conventional water, the buoyancy is activated instantly when submerged. Needless to say, it can be used for quick lifesaving, and it is small, lightweight and highly wearable, and can be worn comfortably regardless of age, gender, season, place, type of action, etc. It is possible to provide a pendant life preserver that is rich in decoration, such as being able to adopt a design that you would like to wear yourself.

  In addition, since a water-degradable sealing means is used, a lever or spring that moves the firing needle as in the method of introducing a compressed gas into a floating bag by opening a hole in the compressed gas cylinder used in a conventional lifesaving device with a firing needle or the like Therefore, the number of parts can be reduced, the size can be reduced, and there is no risk of damaging the wearer due to the parts of the firing pin and the lever, and the operation is reliable.

The base body 12 is hermetically communicated with the decorative body 16 and the compressed gas tank 11, and the distal end portion 13 is fixed so as to branch in two directions and protrude from the compressed gas tank 11. A vent pipe 15 capable of ejecting the compressed gas A in the compressed gas tank 11 from the outlets 14, 14 provided facing each other, and the neck string portion 2 has an opening 31 at the tip of the vent pipe 15. And a bladder 3 connected are fitted into 13. In addition, the code | symbol X in drawing shows the state of the normal mounting | wearing, and the code | symbol Y shows the state which submerged and the floating bag 3 expanded.

  The neck string portion 2 is made of, for example, a synthetic resin such as polyamide and is made of a waterproof material, and the inside is made of a strong rubber sheet material such as natural rubber. In addition, a pair of necklace front portions 21 having a floating bag 3 having an expandable dual structure and an internal capacity of about 500 to 600 milliliters, and a base end 22 connected to the necklace front portion 21 And a pair of neck string rear portions 25 each provided with a fastener 24A (24B) at the tip 23. In the present embodiment, the thickness of each float bag 3 is not uniform in the length direction, and the location closest to the back surface is When it is formed to have the smallest diameter and the opening 31 side has a large diameter and swells, the whole exhibits a substantially truncated cone shape.

  The pair of fasteners 24A and 24B are connected to each other and have a strength that is not easily released. In this embodiment, hooks and rings are used, but the present invention is not limited to this. For example, a buckle or the like may be used.

  Further, in the present embodiment, the neck string part 2, the torso string part 4 connected to the lower end of the compressed gas tank 11 of the pendant part 1 and connected to the waist of the wearer by connecting the base ends 42, 42; It has a vertical string 5 that connects the neck string part 2 and the torso string part 4 on the back side of the wearer (the back position of the neck), and the torso string part 4 has base ends 42, 42 at the lower part of the pendant part 1. Are formed from a pair of waistband front portions 41, 41 and a flat belt-like waistband rear portion 44 whose ends are connected to the front ends 43, 43 of the waistband front portions 41, 41.

  The waist strap portion 4 and the vertical strap 5 are arranged so that when the float bag 3 is inflated by placing the pendant portion 1 hung on the neck by the neck strap portion 2 at a predetermined position on the chest, the float bag 3 is around the body. For example, it is used in order to ensure that it is placed in contact with a predetermined position under the jaw without floating.

  As shown in FIGS. 6 to 8, the vent pipe 15 protrudes from the upper portion of the compressed gas tank 11 and is fixed in an airtight manner, and extends from the base end 12 communicating with the inside of the compressed gas tank 11 to the left and right directions. The front end portions 13, 13 are branched, and at each front end portion 13, two outlets 14, 14 are formed so as to be orthogonal to the axis of the internal ventilation passage 17.

  Further, as shown in FIGS. 9 and 10, a flange 18 projects from each distal end portion 13 of the vent pipe 15 at a position closer to the base end side than each outlet 14, and the vent pipe is provided at the opening 31 of the float bag 3. The compressed gas A is received from the opening 31 by covering the flange 18 and locking the opening end 32 from which the annular protrusion protrudes and is covered so that each outlet 14 formed on the side surface 15 is covered. It is airtightly fixed so that it does not leak and does not easily pull out. At this time, the vent pipe 15 and the floating bag 3 may be more firmly fixed by an adhesive (not shown) or a binding member (not shown).

  Further, as shown in FIGS. 11 and 12, the outer periphery of the float bag 3 is made of a material having water-decomposability at the location where the blowout ports 14 and 14 of the opening 31 of the float bag 3 that is crowned at the tip of the vent pipe 15 are located. Even if the compressed gas tank 11 is filled with the compressed gas by the formed sealing means S by tightly tightening the formed sealing band 6, the compressed gas is supplied to the floating bag 3 through each outlet 14 of the vent pipe 15. Will not be ejected.

  And in this Embodiment, a pair of float bags 3 and 3 fixed one end to each front-end | tip part 13 and 13 of the ventilation pipe | tube 15 which protruded from the compressed gas tank 11 in the state which extracted and dwarfed the inside in the float bag 3 The other end of the length fixing string 33 is connected and attached to the ventilation pipe 15 by covering the opening 31 of the floating bag 3, and the vicinity of the outlet 14 is wound from above with the water-decomposable sealing band 6 as described above. The other part is wound with a decorative strip 7 having water decomposability and formed into an integral thin string so that it can be unwound with water, and a certain amount of compressed gas A is injected and filled from the press-in check valve 8 of the compressed gas tank 11 You are ready to wear it as a pendant life preserver.

  In this embodiment, as described above, it is necessary to press-fit and fill a certain amount of compressed gas A from the press-in check valve 8 of the compressed gas tank 11 before mounting, but in this embodiment, FIG. 13 and FIG. As shown in FIG. 2, the press-in check valve 8 is fixed to a pressure inlet 19 formed in a hermetic communication with the inside of the compressed gas tank 11 at the lower part of the compressed gas tank 11, and the compressed gas A which is press-fitted from the outside is orthogonal to the axis of the ventilation passage 82. Then, a fixed portion 84 having a hollow cap shape introduced into the compressed gas tank 11 from the blowout ports 83, 83 provided to face the side surface of the distal end portion 81 and a flange 85 protruding from the fixed portion 84 are opened. The end 86 is locked, and is fixed by a binding member 87 made of, for example, a ring-shaped metal, and the outlet 83, 83 is covered with the outlet 83, 83, and the reverse of the compressed gas A from the outlet 83, 83 is press-fitted from the outside. Since the valve portion 88 has a diameter smaller than that of the fixed portion 84 in the combined state, the valve portion 88 is inserted from the pressure inlet 19 so that, for example, a screw mechanism is provided. Since the pressure inlet 19 and the fixing part 84 can be fixed later by using them, workability is very good. Note that reference numeral 89 in the drawing denotes a seal member that prevents backflow from the gap between the pressure inlet 19 and the fixing portion 84 of the compressed gas A that is press-fitted from the outside.

  In the present embodiment, as shown in FIG. 2, a neck strap portion 2 that is formed in an annular shape with a floating bag 3 on the front is placed on the chest by placing the pendant portion 1 on the chest like a normal pendant. In the lower part of the pendant 1, the waist cord portion 4 to which the base ends 42, 42 are connected is wound around the waist, and the waist strap portion 4 and the neck strap portion 2 are connected to each other at the back portion by the vertical cord 5. Installing.

  In particular, in the present embodiment, as shown in FIG. 21 to FIG. 24, the connecting portion between the floating bag 3 and the neck strap portion 2, the connecting portions 24 </ b> A and 24 </ b> B on the back portion of the neck strap portion 2, and the waist strap portion 4. The waistband front portion 42 and the flat belt-like waistband rear portion 44 of the back portion and the detachable portion are sufficiently strong and can be easily detached, and when worn, the upper end of the vertical cord 5 on the back of the wearer Can be attached / detached at the fasteners 24A and 24B of the neck string portion 2 and the lower end can be attached / detached at the connecting portion 51 of the waist strap rear portion 44 of the waist strap portion 4. When the neck string portion 2 is connected and removed, it can be easily detached by removing it from the lower end of the vertical string 5 and the connecting portion 51 of the trunk string portion 4.

  In the present embodiment, when a length adjusting mechanism (not shown) is provided on the neck strap portion 2, the waist strap portion 4 and the vertical strap 5, the lengths are adjusted according to the wearer's body shape. The pendant-type life preserver can be worn without having to replace it as the child grows up.

  When the wearer unexpectedly falls into the water while wearing the pendant life-saving device according to the present embodiment, the water-decomposable sealing band 6 and the decorative band 7 are released by touching the water, and the floating bag 3 is passed through. The compressed gas A filled in the compressed gas tank 11 is released from the sealed state of the trachea 15 to the air outlets 14 and 14, and is wound around the neck through the air outlets 14 and 14 of the vent pipe 15. The neck of the neck strap 2 is hung from the neck of the pendant 1 to the floating bag 3 and 3 which is uncovered from the water-degradable belt. The buoyancy which floats a part in the state which the mouth nose of the face is exposed to the water surface can be exhibited, and a wearer's respiration can be ensured.

  At this time, in the present embodiment, the inflated floating bags 3 and 3 are reliably placed in contact with predetermined positions under the left and right jaws without floating around the body by the torso string portion 4 and the vertical string 5.

  In the present embodiment, each float 3 has the smallest diameter at the position closest to the back of the wearer and the opening 31 is formed with a large diameter, so that the float of each float 3 is located below the wearer's chin. Since the wearer's position is high, the back side is low, and the wearer is naturally in a supine posture in the water, it is ideal as a posture for waiting for rescue, and can maintain a breathable state even in a fainting state. Moreover, in this Embodiment, when the floating bag 3 expand | swells, there is no worry of a failure | damage with a double structure, and it is a gentle shape also around a neck.

  Further, in the present embodiment, since the length fixing string 33 is passed through the floating bag 3, the gas is not greatly deformed from the original shape when the floating bag is inflated by the compressed gas A. The buoyancy can be obtained with a predetermined amount of compressed gas, so that a sufficient buoyancy is generated with a predetermined compressed gas volume, and a compressed gas tank 11 with a small capacity can be employed. Does not occur. In particular, the present embodiment is a life-saving device that floats the wearer's face on the surface of the water as in the embodiment presented in Patent Document 3, but it is a device that directly attaches a floating bag to the neck. Unlike the lifesaving device of the embodiment presented in Patent Document 3 that cannot be said to be superior, the floating bag 3 is usually placed on the neck string part 2 located between the pendant part 1 and the neck part when worn. Like the pendant, there is no burden on the neck (particularly the front), and when falling, the floating bags 3 and 3 are surely inflated at the position under the chin, and the necessary buoyancy can be exhibited.

  Further, in the present embodiment, the waist strap portion 4 having the base ends 42, 42 connected to the lower portion of the compressed gas tank 11 is wound around the waist when installed, and the waist strap portion 4 and the neck strap portion 2 are Can be held in a state where the floated bags 3 and 3 which are inflated by connecting them at the back portion are securely placed in the lower part of the chin, which is a predetermined position. Even if it is changed, the lifesaving effect can be surely exhibited.

  In the present embodiment, the length fixing string 33 is fixed at one end to the tip portions 13 and 13 of the ventilation pipe 15 protruding from the compressed gas tank 11 and fixed at the other end in the float 3. The string 33 may have one end fixed to the neck string rear portion 25 and the other end fixed to each distal end portion 13 of the vent pipe 15.

  Further, since the sealing band 6 and the decorative band 7 shown in FIGS. 25 and 26 are water-decomposable, respectively, waterproof covers 61 and 71 shown in FIGS. You can also The waterproof covers 61 and 71 are formed so that the wearer (or their guardian, etc.) can freely attach and detach with fixing means such as a hook-and-loop fastener (not shown), and spills drinking water or sudden rain. It is possible to prevent a situation in which the sealing band 6 and the decorative band 7 are unintentionally dehydrated with respect to factors such as water wetting, and the floating bag expands.

  Thus, since this embodiment can prevent the sealing means S from being accidentally released by providing the waterproof covers 61 and 71, the sealing using a conventional firing pin is possible. The same malfunction prevention effect as that of the sealing means using the conventional firing pin can be obtained with a simpler and safer structure than the means.

  The waterproof cover 61 covers the entire surface of the sealing band 6 in a water-tight manner even when the wearer of the pendant life-saving device falls into the water by covering the surface side of the sealing band 6, for example. Therefore, the sealing strip 6 exhibits its water disintegrating function without any problem.

  In addition, if a non-covering portion is provided on a part of the waterproof cover 71 provided in the decorative band 7 (for example, the side in contact with the wearer's chest), moisture is absorbed from the non-covering portion and the whole is dehydrated. The remaining waterproof covers 61 and 71 can be broken by the expansion force of the floating bag 3 so that the floating bags 3 and 3 are not inflated.

  As described above, according to the pendant lifesaving device of the present embodiment, it is possible to achieve a small, simple and safe configuration even if a form in which a floating bag is inflated using compressed gas filled in a compressed gas tank is adopted. In addition, for the purpose of being always worn by infants and children, it is possible to improve the wearability at all times by incorporating decorative elements in the pendant and neck straps, so that they can suddenly fall into the water or get caught in a tsunami. In this case, when the sealing band that immediately forms the sealing means is dissolved into water, the compressed gas is blown into the floating bag and inflated to ensure the wearer's breathing and always be prepared for drowning accidents. It is possible.

  In this embodiment, the compressed gas tank 11 covers substantially the entire surface except for the vent pipe 15 projecting from the compressed gas tank 11 and the pressure inlet 19 formed in the compressed gas tank 11 in order to give the outside decoration. Although it is covered with the formed decorative body 16, for example, the decorative body 16 may be formed so as to decorate only a half surface or a part thereof. Of course, there is no problem even when the compressed gas tank 11 and the decorative body 16 are formed integrally.

  Further, in the present embodiment, the decoration body 16 of the pendant unit 1 is a very general shape having a thin plate-like oval surface. However, a character such as an animal, a plant, a hero or a princess, or a round shape, a star shape, or other geometry. Designs that can be worn with preference from infants to adults according to the gender, age, preferences, etc. of the wearer are possible, and the sealing band 6 and decoration are designed so that everyone can wear them everyday. The total design including the band 7 is possible, and the size can be commonly used by everyone by adjusting the lengths of the neck string part 2, the torso string part 4 and the vertical string 5 in advance or appropriately at the time of wearing. is there.

  Further, in the present embodiment, the compressed gas tank 11 is arranged in the pendant portion 1 attached to the chest, and the compressed gas tank 11 is cooled by the heat of vaporization of the compressed gas A ejected from the compressed gas tank 11 when submerged, so that the wearer In order to prevent harm, it is preferable to form the entire decorative body 16 covering the compressed gas tank 11 or the back surface portion that touches the wearer with a material having a heat insulating effect, and the decorative body is the entire compressed gas tank 11. Even if the cover is not covered, it is preferable to provide heat insulation means at least on the part that touches the chest of the wearer (not shown).

  Furthermore, in the present embodiment, the air bag 3 has a double structure, so that airtightness is ensured and safe. However, it may be single by selecting a material, and at least the open end 32 of the air bag 3 may be used. The portion of the vent tube 15 that covers the vent tube 15 from the tip 13 to the position beyond the outlets 14 and 14 may be formed with a slightly thick rubbery single structure, The opening end 32 is annularly thickened to increase the strength, and can be hermetically fixed to the vent pipe 15 and can be made strong so as not to be removed even when the floating bag 3 is inflated by the compressed gas A.

  In addition, it is conceivable that the floating bag 3 part is also cooled by the heat of vaporization accompanying the ejection of the compressed gas A from the compressed gas tank 11 when submerged. In the case of a double structure as in the form, it is preferable to use a material having a heat insulating effect at least on the outside.
