2. Description of the Related Art Japan is a very blessed geographical area, surrounded by seas on all sides, has refreshing rivers flowing out of steep mountains, and has dotted scenic lakes in some places. Because of the environment, on holidays, families can play in the water on the shores and rivers, or engage in surf fishing and boat fishing.
People of all ages, including marine sports such as surfing and boldly trying to go down the river by canoeing, enjoy a variety of leisure activities at the waterside, regardless of age and gender. Is expected to increase even further.

[0003] Many people who work on the seaside, lakes, marshes, rivers, etc., have a strong knowledge of outdoor and leisure activities, and try to ensure that they are equipped with sufficient equipment so that they do not omit safety measures. Forget about the harshness of dealing with nature or become overconfident and prepare in advance despite the equipment that must be prepared according to the natural environment such as life jackets, helmets, gloves etc. Miserable, such as neglecting to do it or preparing it, but not actually wearing it, encountering a sudden accident and experiencing an extremely dangerous experience, or losing life due to luck It is a fact that there are also many cases that lead to a serious ending.

[0004] In particular, water motorcycles and boats, which have become widespread following the marine leisure boom, require the wearing of life jackets due to their danger. However, they are shunned for reasons such as "cannot coordinate with boats and clothes", "is troublesome", "not good looking", etc. However, because they do not have the habit of giving advice and wearing caution, even people almost at the level of beginners are inspired by such a tendency and enjoyed the boom marine sports completely defenseless, and as a result, Where I was supposed to be safe if I wore a lifesaving device, I encountered a miserable water accident involving human life because I neglected to wear it It is unending at all the case, such as would.

[0005] In order to prevent the occurrence of flood accidents due to such careless actions, the Ministry of Transport does not limit the color of life jackets to colors such as fluorescent orange and yellow, which are easily found at sea.
Recognition of wearing colorful and fashionable life jackets such as blue, black, green, and purple was accepted, and the ministry ordinance was amended to increase the rate of wear, and finally serious efforts were made to improve the safety of marine leisure. . However, general life jackets are made of the best type of thick material,
There is a strong impression that the movement of the upper body is restrained when worn, especially the delicate movement of the center of gravity and accurate handling,
Such as direct feel from the skin, quick wear, etc.
For marine sports enthusiasts, where lighter clothing at or near bare skin is a more advantageous condition, they will hate the use of such thick lifejackets.

[0006] As described above, the present invention is notorious for the fact that conventional life vests are cramped, and they are cumbersome and uncomfortable to wear, and it has been impossible to increase the wearing rate for a long time. Having doubts about the circumstances, he quickly began to develop and research on a life-saving rescue device that could be worn easily, did not restrain the body, and ensure high safety. As a result of repeating trial and error, many trial productions, and experiments over a long period of time, this time, we finally succeeded in realizing a waist bag for lifesaving with a new structure, and in the following, this The configuration will be described in detail together with a representative embodiment of the present invention.

Formed on the left and right outer wall surfaces of the bag body 1, respectively.
It is detachably attached through a not-shown hook hole formed in a hard resin detachable plate portion integrally provided at the end thereof, and a bag is attached to the detachable plate portions of the floating bag bodies 5, 5. The small cylinder 3 provided in the main body 1 is formed with the ends of the pipe lines 6, 6 connected through the operation switch 4, and the injection ports 51, 51 which are detachably mounted. .

At the normal stage, the pair of left and right floating bag bodies 5 and 5 are folded and miniaturized and mounted on the left and right outer wall surfaces of the bag body 1. Has a built-in check valve mechanism (not shown) for preventing the compressed gas filled in the floating bag body 5 from leaking out when the pipe line 6 is disconnected. In addition, an openable / closable exhaust port 52 is formed in any suitable place of the floating bag body 5.

The operation switch 4 has a valve mechanism (not shown) connected to the nozzle outlet of the small cylinder 3. The valve mechanism extends from the operation switch 4 and extends to the outside of the bag body 1. The sub-switch 42 is connected to the sub-switch 42, and when submerged in water, the sub-switch 42 is energized to automatically open the valve mechanism of the operation switch 4.

The structure may be such that the switch mechanism urged in the opening direction is locked by a stopping part made of a water-soluble material that dissolves immediately after flooding, or when water is flooded, It is also possible to adopt a configuration in which a chemical reaction occurs to cause deformation such as disappearance, reduction or expansion, and the valve mechanism of the operation switch 4 is automatically opened.

Further, as shown in the perspective view of the water-saving life-saving waist bag in FIG. 7, the floating bag body 5 is folded and reduced, and is detachably attached to the outer wall surface at the bottom of the bag body 1. In addition to the above, the small cylinder 3 is not filled with compressed air or compressed oxygen, but is filled with a foamed resin material in a molten state which starts to cure immediately after being released and a compressed gas. It is also possible to adopt a configuration in which the foamed resin material is injected and supplied together with the compressed gas.

[0027]

The waist bag for lifesaving according to the present invention having the above-mentioned structure is worn and used in a state in which the belt body 2 is wound around the waist. When it becomes necessary, the buoyancy part 43 of the auxiliary switch part 42 shown in FIG. 1 rises, and when the buoyancy part 43 is grasped and pulled out, the operation switch 4 is operated and the compressed air sealed in the small cylinder 3 is compressed. Alternatively, compressed oxygen is ejected, and the compressed gas ejected is supplied to the inlet 51 of the bladder 5 through the piping 6.

The floating bag 5 supplied with the compressed gas is instantaneously expanded and deployed from the previously folded and reduced state as shown in FIG. 2 to form an annular floating ring. Due to the expansion, the floating bag 5 forcibly opens the opening / closing opening 11 of the bag body 1 and jumps out of the bag body 1. The air or oxygen supplied into the air bladder body 5 can be released by opening the exhaust port 52. In particular, in the case of oxygen, the air or oxygen can be used for inhaling oxygen. At this time, as long as the gas remaining in the small cylinder 3 is present, even if the internal pressure is reduced by the discharge, the compressed gas is continuously supplied into the floating bag 5 to keep the floating bag 5 at a constant internal pressure. The function as the floating bag body 5 can be maintained.

Similarly, as shown in FIG. 3, in the case of a lifesaving waist bag in which the floating bags 5 and 5 are folded and reduced in size on the outer wall surface of the belt body 2 and stored, an auxiliary switch is provided in the event of a water shortage. When the buoyancy part 43 of the part 42 is grasped and pulled out, the operation switch 4 is operated and the small cylinder 3 is operated.
Compressed air or oxygen inside is ejected, and the air bladders 5, 5 expanded by receiving forced gas supply push away covering cloths 21, 21,... Covering the outside as shown in FIG. It expands and expands instantaneously.

Further, in the water-saving life-saving waist bag shown in FIG. 5, the auxiliary switch portion 42 provided on the operation switch 4 is automatically set in the small cylinder 3 almost at the same time when it is submerged without any special operation. The compressed air or compressed oxygen is injected and supplied to the floating bag 5 side, and the expanded floating bag 5 which has been supplied with the compressed air or compressed oxygen can be removed from the bag body 1, and The detached floating bag body 5 is prevented from leaking the contained gas at the moment when the piping 6 is disconnected by the check valve mechanism built in the inlet 51 to maintain the internal pressure, and as an independent floating bag. Since it can be used, it can also be used for rescue of third parties.

Further, if the exhaust port 52 provided in the floating bag body 5 is opened, the compressed air or compressed oxygen contained therein can be released as required, and the exhaust port 52 can be released. By closing 52, it is possible to continue using it as a floating bag, and when the amount of stored gas is insufficient, the end of the pipe line 6 is again connected to the inlet 51 of the floating bag body 5 in a separated state. When this is done, the check valve opens the sealing state up to that point and again releases the compressed gas to the floating bag 5.
And a sufficient amount of air or oxygen can be injected.

Further, in the case of a structure in which a foamed resin material in a dissolved state is supplied together with a compressed gas into the floating bag body 5 like a waist bag for lifesaving shown in FIG. 7, the foamed resin is filled. The inflated and unfolded floating bag body 5 can generate sufficient buoyancy as a floating bag, and even if the floating bag body 5 is torn by any factor, it is sealed and hardened. Since the foamed resin is an independent molded body and keeps the original shape of the floating bag 5, it functions as a floating bag regardless of the presence or absence of the floating bag 5.

[0033]

As described above, according to the lifesaving waist bag of the present invention, a life jacket which is bulky as a whole and takes a lot of time to mount, and is worn on the upper body until now. Unlike a waist pouch that can be easily worn on the waist, once the waist circumference is adjusted, it can be easily attached to and detached from the waist, and the floating bag body is folded and reduced in size Since it is structured to be stored or attached to the bag body and / or the belt body in the state of being removed, it becomes extremely small and light as a water rescue lifesaving device, eliminating the discomfort of the wearer when wearing it, and In addition to being able to take care not to hinder the agile action of the person, the buoyant body inflates and unfolds instantly in Molds, in which Su features can be obtained that would be helpful to save lives.

In particular, the water-saving life-saving waist bag having a structure representative of the present invention, which has been described in the embodiment, has an opening / closing opening 11 at an upper portion of the bag body 1 capable of accommodating the small cylinder 3 in addition to the above-mentioned features. Forming a storage space portion 12,
In this storage space, it is possible to store items required in the event of a water shortage, such as a smoke tube, emergency food, rescue equipment, ropes, etc., or to store compressed air or compressed oxygen in a small cylinder 3. In the structure in which the inflatable floating bag body 5 is detachable from the bag body 1 or the belt body 2, the floating bag body 5 is detached, and the inflatable floating bag body 5 is disengaged without putting on a lifesaving device. In the case where the non-return valve mechanism is incorporated in the floating bag body 5 injection port 51, it is possible to reliably prevent the leakage of the internal gas at the time of disengagement. Further, in the case where oxygen is filled as a compressed gas, the openable and closable exhaust port 52 is opened as needed,
Utilizing the oxygen sealed in the floating bag body 5, it can be applied to oxygen inhalation.

In the case where a foamed resin material in a dissolved state which cures within a short time after being discharged is enclosed in the small cylinder 3, the foamed resin material is injected into the floating bag 5 together with the compressed gas, and the foamed resin is immediately foamed. The resin material is filled according to the shape of the floating bag body 5,
Immediately thereafter, even if the floating bag 5 is damaged by an external force such as colliding with the hull or other floating matter after the fall, the hardened foamed resin material remains in the floating bag 5. There is an advantage that the buoyancy can be maintained by maintaining the shape of the airbag, and the role as a life-saving device can be prevented from being lost. If it is arranged in an exposed state and is configured to automatically blow out the compressed gas in the small cylinder 3 by dissolving, energizing or chemically reacting immediately after flooding, the victim may be stunned or injured. Even when the operation switch 4 cannot be operated as desired, the effect that the floating bag body 5 is automatically expanded and expanded upon landing on water to obtain a function as a floating bag can be expected. It made.

When the auxiliary switch 42 for manual remote control having the buoyancy portion 43 made of an air pocket, a closed-cell foam body, or the like is incorporated in the operation switch 4, the buoyancy portion 43 is brought into contact with water when it comes in contact with water. Since the person ascends naturally, the victim can reliably find the position of the auxiliary switch section and operate the operation switch 4 even when immersed in water,
For those who are immersed in water and fall into a confused state and can not make a calm decision, it will be useful as a reliable life-saving device.Furthermore, two or more small cylinders are provided, and each small cylinder spout In the case where a separate piping path is formed between the airbag and the floating bag inlet, and an individual operation switch is provided independently and individually for each small cylinder nozzle or each piping path, any small cylinder, operation switch, piping Even if the road or the bladder inlet is damaged or obstructed, a compressed gas is supplied from another system, and an extremely safe life-saving device can be obtained in which the bladder can be reliably expanded. .

As described above, the water-saving life-saving waist bag according to the present invention can achieve the intended purpose with its novel structure, is easy to manufacture, and has a reduced unit cost of the life jacket. In comparison, it can be much more economical, it can be attached and detached like a normal waist bag, the color and shape of the outside can be freely selected, and it is stored in a folded state Or, if the attached floating bag is set to fluorescent orange or yellow, which is easy to find in the event of a distress, it does not impair the design of the waist bag, so it is possible to secure enough fashion and incorporate the trend Because it is easy, a wide variety of products can be developed, and the use of life-saving rescue equipment, which has been sluggish in various water sports, can be greatly increased. Been highly evaluated in the turbocharger over industry and marine sports industry, available across a wide range, it is expected to continue to spread.
