Description

[Detailed Description of the Invention] (Industrial field of application) This device protects the body from water damage by allowing swimmers to wear it on their waists and inflate it to raise their body in case of emergency. The belt-type life-saving float bag.

(Prior Art and Problems) As a life-saving device for preventing water accidents, which has been proposed hitherto, a floating bag for inflating air to inflate, a life jacket, etc. have been widely used.

When a swimmer wears such a life-saving device such as an air-inflatable bladder on his / her body to prevent water accidents and tries to swim or dive in the sea or lake, the life-saving device itself is bulky. Therefore, swimmers and others often avoid such life-saving devices and wear them because the resistance to water becomes very large and it is difficult to swim, and it becomes an obstacle. Therefore, in the unlikely event that an unexpected situation occurs when swimming in an unprotected state where life-saving equipment is not worn, and if the rescue cannot be done in time, a precious human life will be lost.

Therefore, this invention was devised in consideration of the existing circumstances such as the above, and even if an unexpected situation occurs during swimming, the floating bag body attached to the waist is instantly inflated to provide sufficient buoyancy. In addition, it is possible to secure the respiratory activity of the wearer as if the wearer's head and the like were out on the water surface while being positioned on the chest area under the armpit of the wearer, and the danger was eliminated. The purpose of the present invention is to provide a belt-type life-saving floating bag that enables a wearer who swims by swimming to save life safely.

(Means for Solving the Problem) In order to achieve the above-mentioned object, in the present invention,
It is inflated and is worn loosely around the chest area including the armpit of the wearer.In a non-inflated state, it is larger than the waist area of the wearer, and its allowance can be expanded and contracted. A ring-shaped floating bag body 1, a gas supply bag 3 which is in communication with the floating bag body 1 via a ventilation hole 4 and which is attached to the outside of the floating bag body 1 and which can be opened and closed and which is open and closed. The gas container 12 is detachably mounted in the bag 3, is arranged along the ring direction of the floating bag body 1 and is replaceably attached to the holder 11 by operating the gas supply bag 3 from the outside. The gas supply device 2 for supplying the high-pressure gas in the gas container 12 into the floating bag body 1 through the ventilation hole 4 by forcibly opening it through the opening means 14 of the operating lever 17 and the end portion of the gas supply bag 3. Outside of the main body 1 of the floating bag with the inside surface and the margin part folded in And a fastener 8 for detachably joining and fixing the surfaces so that they are separated from each other by the inflation pressure of the floating bag body 1.

(Operation) In the belt-type life-saving floating bag according to the present invention, when the non-inflated floating bag body 1 is attached to the waist of the wearer, a long margin portion as compared with the waist is folded inward, for example. In this state, the outer surface of the floating bag body 1 and the inner surface of the end portion of the gas supply bag 3 are joined by the fasteners 8 so that they are firmly attached around the waist of the wearer. In the mounted state, the floating bag body 1 is completely flat and surrounds the waist, so that the body movement of the body during swimming is not restricted at all.

The gas supply device 2 installed in the gas supply bag 3 has an operating lever 17 which is operated by leverage from the outside of the gas supply bag 3 in case of emergency.
The gas container 12 is forcibly opened by operating the opening means 14 of the gas supply bag 3 and the gas filled in the gas container 12 is supplied.
It suddenly spouts inside. When the gas is filled in the gas supply bag 3 by this ejection, the ventilation hole 4 guides and supplies the gas into the floating bag body 1 to expand the floating bag body 1.

The inflatable buoyancy bag main body 1 peels and releases the joining by the fasteners 8 at the end of the gas supply bag 3 attached to the outside of the buoyancy bag body 1 itself, and the buoyancy bag body 1 extends its folded portion to extend the whole. Greatly expands. The inflated bladder body 1 moves upward from the waist position of the original wearer who was worn in a flat state by its own buoyancy, and reaches the chest position including the armpit of the wearer, Turn your body upwards and make sure that your shoulders and head etc. float above the water surface.

The attachment / detachment operation for the fastener 8 that detachably attaches and fixes the inner side surface of the end portion of the gas supply bag 3 and the outer side surface of the floating bag body 1 without touching the gas supply device 2 is performed.
Is expanded and pulled out from the body, and contracted and attached to the body.

(Embodiment) In the following, one embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 shown in the drawings is a floating bag body, for example, a ring-shaped bag made of a nylon resin-based airtight material with an extremely thin wall thickness. The diameter is slightly larger than the armpit of the wearer who swims in the state of being inflated by inflating air, that is, slightly larger than the chest circumference, and the diameter around the chest area including the armpit is gentle. It should be worn in such a state that its volume is such that sufficient buoyancy in water can be obtained according to the weight of the wearer. Then, in the non-expanded flat state in which air is not injected, as shown in FIG. 1, the entire upper and lower edges along the circumferential direction are folded toward the center of the inner side to It has a seam along the center so that it can be folded in a compact state where the whole becomes a narrow belt shape.

In addition, the floating bag body 1 can be used for an emergency or the like.
A gas supply device 2 for injecting air is provided inside.
The gas supply device 2 is a small bag-shaped gas supply bag 3 attached to the outside of the floating bag body 1 while being in communication with the floating bag body 1.
And a gas ejection mechanism 10 disposed in the gas supply bag 3, and the gas ejected by the operation of the gas ejection mechanism 10 that is forcibly operated in an emergency or the like is the gas supply bag 3
By being forcibly supplied from the inside of the floating bag body 1,
To inflate.

The gas supply bag 3 is attached to the outer peripheral surface of the floating bag body 1 so as to be in close contact with the outer peripheral surface of the floating bag body 1 by communicating with a small-diameter air hole 4 opened at an appropriate position on the outer peripheral surface of the floating bag body 1. The bag 3 and the bag 3 are communicated with each other only through the air holes 4, and the gas supply bag 3 itself is made of the same material as the floating bag body 1.

Further, in the illustrated example, since the gas ejection mechanism 10 is provided in the gas supply bag 3, one end of the gas supply bag 3 itself is closed and the other end is opened to form the insertion port 5. The pouch itself is formed by closely fixing the pouch itself to the outer peripheral surface of the floating bag body 1 and then inserting the gas ejection mechanism 10 into the pouch through the insertion port 5 to seal the insertion port 5. As shown in the figure, the gas jetting mechanism 10 is hermetically sealed by inserting two strip-shaped plate pieces having concave and convex portions that mesh with each other outside the pouch insertion port 5 in the vertical direction, that is, as shown in FIG. The sealing member 7 is arranged along the direction orthogonal to the circumferential direction and is screwed 6 to each other. The gas supply bag 3 composed of this small bag is joined and fixed so that the inner surface of the end portion of the insertion port 5 is detachably attached to the outer peripheral surface of the floating bag body 1 so that the mounting position can be freely adjusted (tightening margin). The fastener 8 is, for example, a fastener of a surface fastener, and is a male and female surface fastener material disposed on the inner surface of the end of the gas supply bag 3 at the insertion opening 5 and the outer peripheral surface of the floating bag body 1 that faces the end surface. One of them is longer than the other in the circumferential direction of the floating bag body 1. By doing so, when the floating bag body 1 itself is folded into a flat shape and is worn around the waist of a swimming wearer, as shown in FIG. It can be mounted by being folded in and joined by a fastener 8 on the outside of the folded portion. In addition,
By forming the sealing member 7 with a rigid member, the tightening member 8 is a flexible member when the air is injected into the floating bag body 1 to expand the air bag main body 1. There is an advantage that the joining due to can be quickly peeled off and released, and the inflation and expansion operation of the floating bag body 1 in an emergency can be smoothly performed.

On the other hand, the gas ejection mechanism 10 is a holder that serves as a base body.
11, filled with high pressure gas such as liquefied carbon dioxide,
The gas container 12 attached to the holder 11 and this gas container
Opening means 14 for forcibly opening the lid plate 13 in the opening of 12 is filled with the gas from the opened gas container 12 through the ventilation hole 4 and the floating bag body 1 It is provided inside.

The holder 11 is arranged substantially orthogonal to the circumferential direction with the base portion 11A arranged along the circumferential direction which is the direction of the ring of the floating bag body 1 when inserted into the gas supply bag 3 as shown in the figure. The gas container 12 is formed in a substantially L-shape on the front including the mounting portion 11B, and the gas container 12 is detachably mounted in a screwed manner from the outside of the mounting portion 11B. 12 can be replaced by opening and closing the sealing device 7.

The gas container 12 is formed of a thin metal cylinder, and can be screwed and set into the mounting portion 11B of the holder 11 so as to be replaceable by a male screw provided at the opening end portion thereof. It is closed by a cover plate 13 made of a very soft metal piece.

The opening means 14 is supported at the tip of the base 11A of the holder 11 so as to be substantially parallel to the mounting portion 11B, and has an operating lever 15 having an opening protrusion 16 facing the opening end of the gas container 12, and a gas at this operating lever 15 end. An operating lever 17 supported in a substantially parallel manner to the container 12 and connected to the container 12, the end of the mounting portion 11B, and the operating lever 1
It consists of a lever lever 18 that swings and connects the positions in the middle of 7
Actuating lever 15 that swings when the operating lever 17 is gripped
The opening projection 16 of the above is configured to penetrate the cover plate 13. That is, the operating lever 15 that is substantially parallel to the mounting portion 11B of the holder 11 and the lever 18 that is inclined to the rear side of the gas container 12 outside the holder 11 with respect to the tip of the mounting portion 11B. It has a parallel link structure facing each other, and as shown in FIG. 3, it is operated by a grasping operation of the operating lever 17 that is close to the gas container 12 with respect to the gas container 12. Attach lever 15 to mounting part 11B
It is rocked to the side, so that the opening projection 16 is
Is pressed into the gas container 12, enters the gas container 12, and is pierced by the cover plate 13
The gas in the gas container 12 is ejected from the opening.

Further, the tip of the opening protrusion 16 is sharply formed so that the lid plate
To facilitate easy press-fitting into 13, the length of the operating lever 17 is made longer than the length of the gas container 12 so that the gripping operation can be performed quickly, and further, between the base 11A and the operating lever 15, The pivotal support structures of the operating lever 15 and the operating lever 17, the mounting portion 11B and the lever lever 18, and the supporting portions of the lever lever 18 and the operating lever 17 are set so that the swinging thereof is slightly tight. It is good to keep it immobile except during operation.

It should be noted that the opening protrusion 16 is provided when the operating lever 15 itself swings as the operating lever 17 approaches the gas container 12 side,
Since the cover plate 13 is pierced in a vertical hole shape along its swinging direction to open the cover plate 13, even if the opening projection 16 pierces the cover plate 13, sufficient gas is blown out above and below the swinging direction. Since there are various voids, there is no problem in ejecting the gas in the gas container 12.

Next, to explain an example of use, when swimming, it is worn by winding it around the waist, and when winding, the floating bag body 1 itself is folded inward at both side edges to form a narrow width. In addition, when the gas supply device 2 side is arranged on the front side and the allowance portion when wrapped around the waist is folded inside the floating bag body 1 (see FIG. 1), the gas supply device 2 supplies gas in the form of a pouch. Bag 3
The insertion port 5 side is joined and fixed to the outer peripheral surface of the floating bag body 1 by the fastener 8 to be attached around the waist.

Then, during swimming, for example, when swimming in the depth, when the feet or the like tend to drown and tend to drown, the gas from the outside of the gas supply bag 3 can be grasped, that is, the gas in the gas supply device 2. The ejecting mechanism 10 may be grasped from above and the operating lever 17 of the opening means 14 may be grasped so as to come close to the gas container 12 side. Then, the opening protrusion 16 of the operating lever 15 pierces the lid plate 13 of the gas container 12,
The gas container 12 is opened to fill the gas supply bag 3 with the gas, and the gas is rapidly supplied into the floating bag body 1 through the ventilation holes 4 accordingly. The gas supplied into the floating bag body 1 expands the floating bag body 1, and in the expansion process,
The part that is folded at the time of mounting spreads upward and downward and outward of the floating bag body 1 to form a round tubular shape. When inflating in this way, the fasteners 8 that fastened the gas supply bag 3 to the outer peripheral surface of the floating bag body 1 are gradually peeled off and released, so that the inside of the floating bag body 1 at the time of mounting is inward. Also, the folding margin portion is expanded to make the floating bag body 1 itself into a ring shape having a large diameter. As a result, the floating bag body 1
It is released from the waist and moves to the armpit of the wearer while floating due to its buoyancy, imparting buoyancy to the wearer and lifting the wearer's own upper body (see Fig. 4). After that, you should swim by yourself and wait for the rescue.

It should be noted that the gas supply device 2 does not cause an emergency such as during swimming.
If you don't use the fasteners, tighten the fasteners 8 after swimming.
The floating bag body 1 is expanded only by releasing the joining and fixing, and the floating bag body 1 is pulled out from the body without touching the gas supply device 2, and is prepared for the next use.

Although not shown, by cutting and sealing one place of the floating bag body 1 and attaching a latch there,
It can be used like a trouser belt, and by making the latch attachment part slidable, it can be expanded and contracted, which is convenient. Furthermore, if the size of the floating bag body 1 itself is formed into a substantially life-size tubular shape from the waist portion in the vertical direction, and is folded and filled in a gas container 12 having a gas capacity sufficient to expand it, For example, even if a person falls down during work in the harsh cold sea, the whole body will be in the tubular floating bag body 1 as it expands, and the whole body will lie down due to the buoyancy imparted to the whole body. As it floats to the surface of the sea, even if clothes get wet temporarily when it falls, it is possible to avoid sudden frost death and wait for rescue during that time. In addition, if the surface of the body 1 of the floating bag is made to have a night-light color, it becomes a large light-emitting body even if it falls into the sea at dark night, and it can be surely found even from a long distance to facilitate rescue.

(Effect of the device) This device is configured as described above, and as a result, during normal swimming, you can swim without any problem while wearing it on your waist, and in an emergency such as when you are about to drown. Then, the floating bag body 1 can be instantly inflated by the gas supply device 2, and the resulting buoyancy can be floated on the water surface with the upper body up, thereby preventing a water accident or the like.

That is, in this device, this is worn loosely around the chest area including the armpit of the wearer in the inflated state, and is larger than the waist area of the wearer in the non-inflated state,
The floating bag main body 1 having a ring-like shape with a slack portion that can be expanded and contracted is communicated with the floating bag main body 1 through a ventilation hole 4 and is a hermetically sealed state attached to the outside of the floating bag main body 1. A gas supply bag 3 that can be opened and closed, and a gas container 12 that is arranged in the gas supply bag 3 so as to be freely taken out, is arranged along the ring direction of the floating bag body 1, and is exchangeably attached to a holder 11. Is forcibly opened through the opening means 14 of the operating lever 17 which is leveraged by an external operation to the gas supply bag 3, and the high pressure gas in the gas container 12 is supplied into the floating bag body 1 through the ventilation hole 4. Floating bag main body 1 in which the supply device 2 and the inner side surface of the gas supply bag 3 end and the margin are folded.
And the fastener 8 for detachably joining and fixing the outer surfaces of the bladder main body 1 so as to be separated from each other by the inflation pressure of the floating bag body 1, whereby the freedom of body movement during wearing and swimming,
It is possible to obtain ease of operation in an emergency, instantaneous expansion of the body 1 of the floating bag, floating of the upper body of the wearer, and easy attachment / detachment to / from the body.

Moreover, since the floating bag body 1 can be attached to the waist in the form of a foldable compact belt, it can be swiftly swept without disturbing it, and even if it dive, there is no buoyancy and it is easy to dive. Rigid gas container 12 in 2
Since the gas supply device 2 is disposed along the direction of the ring of the floating bag body 1, the gas supply device 2 does not interfere with the operation of the normal swimming action. And since it is possible to swim while wearing it on the waist, even if you are about to drown, you can inflate the upper body of the wearer by operating the gas supply device 2 and instantly inflating the body 1 of the floating bag, which may cause a water accident. In addition, even if the physical strength is exhausted at the bottom of the water by diving, if the head is directed to the surface of the water and the gas supply device 2 is operated to inflate the body 1 of the floating bag, it will naturally float up. .

Furthermore, even in the face of various unforeseen circumstances, the gas supply device 2 located at the center of the front surface of the floating bag body 1 when mounted is lightly grasped, that is, the operating lever 17 is brought close to the gas container 12 side. Gas container 12
Since the structure is such that gas blows out from the floating bag main body 1 through the ventilation hole 4, the floating bag main body 1 is inflated, so that it can be used by anyone without fear of erroneous operation.

At the time of mounting on the body, the floating bag body 1 has its ring shaped like a belt and is folded and reduced with a margin portion, which is longer than the circumference of the mounting site, being inward, for example, and the end portion of the gas supply bag 3 and the outside of the floating bag body 1 are reduced. Even if it is intended to be worn by tightening it on the waist while being fixed to the surface via the fasteners 8, when the air bag body 1 is inflated by the gas supply device 2 which is activated in an emergency, the expansion force of the air bag body 1 is increased. By making the outer surface arcuate, the fastener 8 that is the fixing portion between the floating bag body 1 and the gas supply bag 3 is automatically peeled off and the fixed state is released. By releasing the fasteners 8 in this way, the margin portion of the floating bag body 1 also expands and at the same time expands, so that the entire floating bag body 1 has a large diameter, and a sufficient clearance is provided between the waist of the wearer and the floating bag body 1. As a result, the body 1 of the floating bag floats away from the waist and moves up to the armpit, which is the chest. Therefore, by moving the buoyancy force of the floating bag body 1 above the body, the center of gravity of the body is also lowered, the vertical balance of the whole body is balanced, and the shoulders and the head can be surely floated above the water surface. You can wait for rescue in a stable state.

Further, when the floating bag body 1 is removed from the body when the gas supply device 2 is not used after swimming on the body, it suffices to release the joining and fixing state by the fasteners 8. Even in such a case, the inside of the gas supply bag 3 is removed. It is not necessary to give any operation to the gas supply device 2 of FIG. Therefore,
The attachment / detachment to / from the body can be easily performed only by attaching / detaching the fasteners 8, and the gas supply device 2 is arranged in the gas supply bag 3 in a state in which the attachment / detachment can be continuously operated no matter how many times the attachment / removal is repeated. Therefore, for example, there is no forgetting to set when wearing, and it can be surely used when wearing and swimming. Further, the gas container 12 emptied by using the high pressure gas can be taken out by the opening of the gas supply bag 3 and replaced with a new one, so that it can be used any number of times.

Furthermore, the floating bag according to this invention is not only used for swimming,
For example, it is light because it does not hinder physical movement at all when it is used for on-board work or various types of leisure on the water, and even if it falls into the water or is thrown out, it can prevent accidental water accidents. , Its use is extremely wide.
