≪Concept≫
FIG. 1 is a diagram showing the concept of the present invention.

  The present invention relates to a folding storage type floating ring for protecting the life of a water drop person and facilitating rescue. When children are enjoying leisure activities especially on a boat, children may not be aware of it even if it falls. At that time, if the child wears the folding storage type floating ring according to the present invention as a life jacket, the falling water is automatically detected when the water falls, and the floating ring main body and the radar reflector are automatically deployed. The person who falls down is in a state of floating on the water surface without being drowned by the buoyancy of the floating ring main body. A patrol boat or rescue helicopter searching for a fallen person can easily find a child by searching for a radar reflector. If the transmitter is activated at the same time as the water falls, and the ship's speaker emits a sound to notify the water, it will be possible to rescue more quickly. Furthermore, if a light emitting part is provided on the radar reflecting part or a fluorescent paint is applied, the searcher can easily specify the position of the water drop person even at night. A life preserver having such a search device and automatically deploying is the folding storage type floating ring of the present invention.

  The present invention has a feature that it is an excellent life preserver especially for young children because it automatically detects falling water and automatically deploys to function as a floating ring with a radar reflector. Further, in any of the following Embodiments 1 to 14, it is emphasized that it is a child. However, the present invention invented for such a child is of course a lifesaving device that is very easy for an adult to handle. It is. For example, even if an adult loses consciousness by hitting his head when it falls, such a life preserver is indispensable. If a folding storage type floating ring of a plurality of sizes according to the physique, especially weight, is prepared, a suitable one for children and adults can be obtained. For this reason, the present invention also includes a folding storage type floating ring for adults, which is particularly larger in size of the floating ring main body than that for children.

  Embodiment 1

<Overall configuration of Embodiment 1>
The first embodiment will be described with reference to FIG.

  The first embodiment is a folding storage type floating ring including a floating ring main body part 0201, a support column part 0202, a radar reflection part 0203, a compressed gas holding part 0204, and a compressed gas switch part 0205.

    <Description of Configuration of Embodiment 1>

  The “floating ring main body” is folded and stored, and is in a usable state by being expanded by compressed gas. The floating ring main body may be of any shape as long as it can hold the child's body. For example, the floating ring main body may have a donut shape as shown in FIG. 2, or even a floating ring main body 0301 having a cutout at a part thereof as shown in FIG. It may be a floating ring body part 0302 in which the part is divided into two parts and the part is connected with a string.

  Folding ring main body part is folded and stored means that it is folded in a state where air is removed from the floating ring main body part. FIG. 4 shows an example of a state in which the floating ring main body 0401 is folded. In FIG. 4, the floating ring main body is folded in the radial direction, but may be folded in the circumferential direction when expanded and deployed. Moreover, being folded and stored means being folded and stored in the cover. For example, the folded floating ring main body shown in FIG. 4 is stored with a cover 0404 applied thereto. The folded floating ring body portion 0501 may be stored in a jacket 0502 as shown in FIG. 5, for example, and the folded floating ring body portion 0601 has the best shape as shown in FIG. May be stored in the jacket 0602. In this case, the jacket fabric should be thin.

  When the floating ring body part expands with compressed gas, the compressed gas switch part of the compressed gas holding part is opened and the floating ring body part is filled with gas, folded and stored, and exhibits buoyancy as a floating ring body part. It says to expand to a size that can be done. The minimum volume when the float body expands is greater than the difference between the sum of the weight of the fallen child and the weight of the folding retractable float itself, and the drainage weight drained by the child's body under the surface of the water. It is sufficient if there is a volume that can be obtained. The child sinks if the volume of the floating ring body when expanded is less than this.

  Having a floating ring body part, for example, considering that a child is generally familiar with the use of a floating ring from an early age, the present invention adopts the shape of such a floating ring. is doing. It is considered difficult to stabilize the body on water with waves using life-saving equipment that adults use in a panic situation after falling down. Therefore, it can be said that the shape of the floating ring that is most used for the use in an emergency is safer because the child can unconsciously take a stable state. In general, life-saving equipment is filled with air in front of the body, so it floats on the water surface in a posture that warps backward, but it is dangerous that water enters from the nose when wearing waves. Sometimes. In that respect, if it is a floating ring, the posture can be freely changed to some extent according to the wave, so it can be said that it is easy to ensure safety in the case of a child.

  The “post portion” is folded and stored, and can also form a post from the floating ring body portion toward the sky above the water surface by being expanded. The column can be formed from the floating ring body part to the sky above the surface of the water by expanding. In the folded state, the support is formed together with the floating ring body part in the cover, but the compressed gas switch of the compressed gas holding part is stored. When the part is opened and the floating ring body part, the column part, and the radar reflection part are filled with gas and expanded, the column part can be formed toward the sky above the water surface. The strut portion 0202 illustrated in FIG. 2 is, for example, one strut, but may be a plurality of struts. Moreover, a support | pillar part may have inclination and the support | pillar part should just be formed toward the sky above water surface. Moreover, this support | pillar part may be combined with a radar reflection part. The strength of the supporting column is only required to resist the wind pressure received by the radar reflecting unit and the supporting column attached to the upper part.

  The “radar reflection part” is folded and stored, and is also expanded, so that it can be supported above the support part and disposed above the water surface. It is supported by the support column by being expanded and can be disposed above the water surface. In the folded state, it is stored together with the floating ring main body in the cover, but a compressed gas switch of a compressed gas holding unit. When the part is opened and the floating ring body part, the column part, and the radar reflecting part are filled with gas and expanded, it is supported by the column part and can be arranged above the water surface. Radar reflectors are easily recognized by radar by being placed above the water surface. The radar reflector may be such that the surface is coated with a metal thin film so as to reflect the radar. Further, the radar reflecting portion may be made of a material having a metallic luster that can reflect and visually recognize light when receiving sunlight.

  The “compressed gas holding unit” holds the compressed gas. The compressed gas may be conventional high-pressure air, nitrogen gas, carbon dioxide gas, inert gas (argon gas, helium, etc.), hydrogen gas, and the like. The cylinder material that holds the gas may be a metal or a resin. The metallic material may be stainless steel, titanium, aluminum alloy having high corrosion resistance, or an iron plate or copper plate with anticorrosion plating or coating, or the above-mentioned metal or other metals. The resin material may be a high-strength engineering plastic or vinyl chloride.

  The “compressed gas switch unit” is a switch unit for introducing the compressed gas into the floating ring main body unit, the support column unit, and the radar reflecting unit. The compressed gas switch part is opened when water falls. When the compressed gas switch part is opened, the gas in the compressed gas holding part is introduced into the floating ring body part, the column part, and the radar reflecting part that are folded and stored, and expands.

    <Effect of Embodiment 1>

  The first embodiment completes a small and lightweight life preserver that can be worn by a child like a vest, ensures safety even when the water falls, and also has a radar reflector so that it can be easily searched by a rescue ship or helicopter using a radar. The effect of becoming.

  Of course, the folding storage type buoyancy ring of the present embodiment is a life preserver suitable not only for children but also for adults.

  << Embodiment 2 >>

<Overall Configuration of Embodiment 2>
A second embodiment will be described with reference to FIG.

  The second embodiment is based on the first embodiment, and includes a floating ring main body portion 0701, a support column portion 0702, a radar reflection portion 0703, a compressed gas holding portion 0704, and a compressed gas switch portion 0705. Is a point further having a falling water detection unit 0706.

    <Description of Configuration of Embodiment 2>

  Since the function of the floating ring main body part, the column part, the radar reflection part, and the compressed gas holding part is the same as that of the first embodiment, a detailed description thereof will be omitted.

  The “falling water detection unit” has a function for detecting the falling water and operating and opening the compressed gas switch unit. The falling water detection unit is for detecting the falling water and operating the compressed gas switch unit to introduce the compressed gas into the floating ring main body unit, the support column unit, and the radar reflecting unit. The falling water detection unit may generate, for example, a trigger signal for detecting falling water and operating and opening the compressed gas switch unit. Moreover, the falling water detection part may detect falling water, for example, may destroy itself and may open a compressed gas switch part. The falling water detection includes detection of falling water by water pressure, and detection of falling water by intrusion of water or seawater. FIG. 8 is an example of a flow in which the compressed gas switch unit operates by sensing water pressure. After step 0801 in which the water pressure sensor in the water fall detection unit detects water fall, after step 0802 in which the opening of the compressed gas switch unit is opened, the compressed gas is floated from the compressed gas holding unit, the main ring unit, the column unit, and the radar. Step 0803 is introduced to the reflection unit. In the example of FIG. 8, the falling water detection unit follows such a flow. On the other hand, FIG. 9 shows an example in which water is detected by intrusion of water or seawater and the compressed gas switch unit is opened. The compressed gas switch unit 0904 has an opening 0903 for introducing water or seawater, and when the water is dropped, the water or seawater infiltrates into the lid 0901 installed in the cylinder. This lid always keeps the airtightness together with the valve 0902 so that the compressed gas in the compressed gas holding portion does not leak outside. When the lid reacts with the liquid, it softens and the strength decreases. The lid, which has been reduced in strength, cannot withstand the pressure of the compressed gas, so that the lid “bends and breaks”, and is blown off with the expanding compressed gas to the floating ring body. At the same time as the lid is blown off, the bent valve extends. Further, this valve is brought into close contact with the inside of the pipe by the pressure inside the pipe and functions as a check valve so that gas does not leak from the opening 0903. For example, with such a mechanism, the falling water detection unit operates and releases the compressed gas switch unit. The material of the lid at this time may be any material as long as it is softened or embrittled by being in contact with the liquid. Alternatively, the lid material may be a foaming agent that reacts with the liquid. The strength varies depending on the material, but in the case of a material with low strength, it can be adjusted by increasing the thickness and reducing the tube diameter.

    <Effect of Embodiment 2>

  In order to automatically detect falling water according to the second embodiment, even a child who panics due to falling water automatically functions the folding storage type floating ring of the present invention without performing any operation for operating the apparatus. The effect that it can be made.

  Of course, the folding storage type buoyancy ring of the present embodiment is a life preserver suitable not only for children but also for adults.

  The feature point of this embodiment is that the floating ring body part, the support column part, and the radar reflecting part are folded in a best shape, and the folded floating ring body part is By forming the circumference of the chest and inflating with the compressed gas, the body immediately enters the ring of the floating ring main body.

  The floating ring body part, the support column part, and the radar reflecting part are folded to form the best shape. For example, the folding storage type floating ring can be mounted as shown in FIGS. Say. In addition, the fact that the fuselage is immediately put in the ring of the floating ring main body by expanding with the compressed gas means that the fuselage is placed in the ring 1201 of the floating ring main body as shown in FIG. Is to enter the state. Further, the best shape of the folding storage type floating ring main body is not limited to FIGS. 10 to 12, and may be as shown in any one of FIGS. 4 to 6.

  This folding storage type floating ring can be worn by a child from the head, for example. Alternatively, in the case of the shape shown in FIG. 5 or 6, the folding storage type floating ring may be mounted so as to normally wear a jacket. At this time, the floating ring main body portion is shaped like a floating ring main body portion 0301 as shown in FIG. 3 when expanded. FIG. 12 is a conceptual diagram when the floating ring main body portion, the support column portion, and the radar reflecting portion are completely expanded. The place where the compressed gas holding unit is mounted may be either in front or behind.

  Since this folding storage type floating ring is housed in a compact shape as shown in the conceptual diagrams of FIGS. 10 and 11, there is an effect that the activity is not hindered for children. Furthermore, the position of the compressed gas holding part is preferably on the back side for a child who has a habit of carrying a school bag. In addition, it is desirable that the positions of the center of gravity of the compressed gas holding part and the compressed gas switch part come approximately at the center of the back.

    <Effect of Embodiment 3>

  According to this embodiment, since this folding storage type floating ring can be worn as a vest, even an active and violent child can wear it without a sense of incongruity. Further, since the floating ring main body portion expands so as to capture the trunk, the folding storage type floating ring has an effect that it is easy to ensure safety.

  Of course, the folding storage type buoyancy ring of the present embodiment is a life preserver suitable not only for children but also for adults.

Embodiment 4 will be described with reference to FIG.

  The fourth embodiment is based on the third embodiment, and includes a floating ring main body portion 1301, a support column portion, a radar reflection portion, a compressed gas holding portion, and a compressed gas switch portion. The characteristic point is a shoulder portion 1302. It is a point which has.

    <Description of Configuration of Embodiment 4>

  Since the basic functions of the floating ring main body portion, the support column portion, the radar reflection portion, the compressed gas holding portion, and the compressed gas switch portion are the same as those of the third embodiment, a detailed description thereof will be omitted.

  The feature point of this embodiment is that the floating ring main body portion, the support column portion, and the radar reflecting portion are folded in a best shape and have a shoulder portion. In addition, the shoulder portion has a function of pressing the arm passed through the vest against the expanded floating ring main body portion when the folded floating ring main body portion is expanded by the compressed gas. The shoulder portion is a shoulder portion that can be adjusted to the wearer's arm and can ensure adhesion. The shoulder portion may be configured such that the length of the shoulder portion can be adjusted so that the shoulder portion can be adjusted even when there are individual differences in body shape. Further, the shoulder portion 1302 may have a shape different from that of FIG. For example, the shoulder portion is as wide as a vest as shown in FIG. 5 or FIG. 6, and in some cases, there may be a shoulder portion or a sleeve through which an arm is passed. The purpose of providing the shoulder portion is to prevent the child from leaving the body even if the child panics and goes wild. In addition, the shoulder part can be spilled from the floating ring body part when the body is shaken violently by a high wave after the floating ring body part is inflated or completed, or when a water drop person loses his mind. This is to prevent the person's body from falling off.

    <Effect of Embodiment 4>

  According to the fourth embodiment, a safer folding storage type floating ring is obtained. In other words, there is an effect that the life of the child can be protected even when the body of the child is shaken by a large wave at high waves, or even when the child falls into panic after falling down.

  << Embodiment 5 >>

<Overall Configuration of Embodiment 5>
The content of Embodiment 5 is demonstrated using FIG.

  The fifth embodiment is based on any one of the first to fourth embodiments. The floating ring main body 1401, the support column 1402, the radar reflection unit 1403, the compressed gas holding unit 1404, the compressed gas switch unit 1405, Consists of.

    <Description of Configuration of Embodiment 5>

  Since the basic function is common to any one of the first to fourth embodiments regarding the floating ring main body portion, the support column portion, the radar reflection portion, the compressed gas holding portion, and the compressed gas switch portion, detailed description will be given. Is omitted.

  The feature of this embodiment is that the floating ring body part, the support column part, and the radar reflecting part are electrically connected to each other, and the compressed gas switch part includes the floating ring body part, The compressed gas is released to any one of the support column and the radar reflection unit. The floating ring body part, the support column part, and the radar reflecting part are connected to each other in an air chamber. These internal spaces are continuous spaces without being blocked by a partition wall. To tell. If the compressed gas switch part releases the compressed gas to any one of the floating ring main body part, the support pillar part, and the radar reflecting part, the gas is introduced into all these internal spaces, and the folding storage type floating ring The whole expands. As described above, the reason why the internal spaces of the folding storage type floating rings are electrically connected to each other is that there is an advantage that a compressed gas switch portion having a complicated mechanism is only required in one place. Achieving small size and light weight for the folding retractable float is primarily important. Since the entire foldable retractable buoyancy ring can be inflated only by attaching the compressed gas switch portion to one place, an increase in the weight of the foldable retractable buoyant ring can be suppressed. FIG. 14 shows, for example, the case where the compressed gas switch part is electrically connected to the floating ring main body part. FIG. 14 shows an example in which the gas introduced from the compressed gas holding unit passes through the compressed gas switch unit, first the compressed gas is introduced into the floating ring body, then introduced into the support column, and finally into the radar reflecting unit. ing. In addition, this compressed gas switch part may be connected to another site | part, ie, a support | pillar part, and a radar reflection part.

    <Effect of Embodiment 5>

  According to the present embodiment, since the compressed gas switch portion having a complicated mechanism is only required at one place, there is an effect that it is possible to contribute to weight reduction of the folding storage type floating ring.

  Embodiment 6

<Overall Configuration of Embodiment 6>
Embodiment 6 will be described with reference to FIG.

  The sixth embodiment is a folding storage type floating ring including a floating ring main body 1501, a radar reflecting unit 1503, a string unit 1502, a compressed gas holding unit 1504, and a compressed gas switch unit 1505.

    <Description of Configuration of Embodiment 6>

  Since the floating ring body part, the radar reflection part, the compressed gas holding part, the compressed gas switch part, and the falling water detection part have the same basic function as any one of the embodiments 1 to 5, Description is omitted.

  The “string part” is for connecting the floating ring body part and the radar reflecting part. Unlike any one of the first to fifth embodiments, in this embodiment, the float ring main body portion and the radar reflecting portion are connected by a string portion instead of a support column. This string part has a tubular shape, and when the compressed gas is introduced, the string part is not only filled with gas, but also functions as a gas passage for sending gas into the radar reflection part and the floating ring body part. Fulfill. This is because the radar reflecting portion does not need to be fixed to the floating ring body portion via the support column portion. The string portion is foldable, but when expanded and deployed, it is desirable to have bending rigidity or axial compression rigidity. For example, the shape memory alloy may be inserted in the axial direction of the string portion, or the string portion itself may be made of the shape memory alloy. In addition, the gas held in the compressed gas holding part is used only for the floating ring main body part and the radar reflecting part by using the string part as described above between the radar reflecting part and the floating ring main body part. There is an effect that the gas pressure of the compressed gas holding part can be lowered, or conversely, a large floating ring body part and radar reflecting part with higher buoyancy can be realized. FIG. 16 is a cross-sectional view of the folding storage type floating ring. The compressed gas is released through the compressed gas switch unit 1605 and is first introduced into the floating ring body 1601 and then passed through the floating ring body. It is introduced into the string portion 1602 that is a pipe, and further introduced into the radar reflecting portion 1603 through this string portion, and the entire folding storage type floating ring is expanded.

    <Effect of Embodiment 6>

  According to the present embodiment, since the coupling between the radar reflecting part and the floating ring body part is only a string, a larger buoyancy can be obtained because more gas can be sealed in the floating ring body part and the radar reflecting part. There is an effect that a folding storage type floating ring can be realized.

  << Embodiment 7 >>

    <Overall Configuration of Embodiment 7>

  The seventh embodiment is based on the sixth embodiment, and is a foldable storage type float that includes a floating ring body part, a radar reflecting part, a string part, a compressed gas holding part, a compressed gas switch part, and a falling water detection part. A characteristic point is that the compressed gas is a gas that is lighter than air at normal pressure, and the radar reflector can float above the water surface due to expansion by the compressed gas.

    <Description of Configuration of Embodiment 7>

  Since the basic functions of the floating ring main body, the radar reflecting part, the string part, the compressed gas holding part, the compressed gas switch part, and the falling water detecting part are the same as those of the sixth embodiment, a detailed description is provided. Omitted.

  The feature of this embodiment is that the “compressed gas” is a gas that is lighter than air at normal pressure, and that the “radar reflector” can float above the water surface due to expansion by the compressed gas. . A gas lighter than air at normal pressure means that the density is lower than air at normal pressure. However, in order for the radar reflecting portion to be able to float in the air, it is desirable that the buoyancy generated by this gas in the air is greater than the weight of the radar reflecting portion and the string portion. In addition, the height of 1 m at the maximum is the limit in the case of the support column, but the length of the string unit is several because the cross-sectional area can be reduced compared to the support unit in the case of the string portion. By extending to m, the radar reflector can be floated at a higher altitude. If the altitude at which the radar reflector floats is high, the radar reflector can be easily confirmed from a distance. In particular, even when the waves are high, or at night or under foggy conditions, the radar reflector is easy to see from a distance, making it easier for rescuers to find, so the time to rescue is reduced. Since it requires less, there is an effect that the possibility of rescue increases.

    <Effect of Embodiment 7>

  According to the present embodiment, not only can the radar reflecting part float on the water surface, but also the extension from the string part facilitates confirmation from a distance and shortens the time to rescue.

  << Embodiment 8 >>

<Overall Configuration of Embodiment 8>
Embodiment 8 will be described with reference to FIG.

  The eighth embodiment is based on any one of the first to seventh embodiments, and includes a floating ring main body portion, a radar reflecting portion 1701, a string portion or a column portion, a compressed gas holding portion, and a compressed gas switch portion. In this folding storage type floating ring, the characteristic point is that a reflector means 1702 is further arranged in the radar reflecting portion.

    <Description of Configuration of Embodiment 8>

  With respect to the floating ring main body part, the radar reflecting part, the string part or the column part, the compressed gas holding part, and the compressed gas switch part, the basic functions are the same as any one of the first to seventh embodiments. Therefore, detailed description is omitted.

  The “radar reflecting portion” has “reflecting plate means”, and the reflecting plate means is provided with reflecting plate means whose end is a thin plate metal that is substantially inscribed on the inner wall of the radar reflecting portion. . That the reflecting plate means is substantially inscribed in the radar reflecting portion inner wall means that the reflecting plate means is inscribed continuously or intermittently along the radar reflecting plate inner wall. By substantially inscribed, when the expansion of the folded and reflected radar reflecting portion is completed, the reflecting plate means expands into a shape that can appropriately reflect the radar. That is, the reason why the reflecting plate means expands following the expansion with the expansion of the radar reflecting portion is that the inner wall of the radar reflecting portion and the reflecting plate means are inscribed. As long as it is inscribed so as to be able to follow the expansion of the radar reflecting portion, the joining type may be any type. For example, FIG. 17 shows an example of a spherical radar reflecting portion. When this radar reflecting portion 1701 expands into a spherical shape, the reflecting plate means 1702, that is, three substantially orthogonal disks are developed. It is. By developing these three discs, the reflector means is completed, and a radar reflecting portion is provided for efficient radar reflection.

    <Effect of Embodiment 8>

  According to this embodiment, when the reflector means is substantially inscribed in the radar reflector, the reflector means is completed following the expansion of the radar reflector.

  Embodiment 9

<Overall configuration of Embodiment 9>
Embodiment 9 will be described with reference to FIG.

  The ninth embodiment is based on any one of the first to eighth embodiments, and the floating ring body 1801, the radar reflection unit 1803, the support column 1802, the compressed gas holding unit 1804, and the compressed gas switch unit 1805. And a folding storage type floating ring comprising a check valve 1806 on the support column.

    <Description of Configuration of Ninth Embodiment>

  Since the float ring main body part, the radar reflection part, the string part or the column part, the compressed gas holding part, and the compressed gas switch part have the same basic functions as any one of the first to eighth embodiments. Detailed description is omitted.

  The “post” has an air blow check valve for a person to blow air through the mouth. When a person blows air through the mouth, it means blowing when the foldable retractable float cannot sufficiently expand. In consideration of the fact that such an air blowing check valve is used by a child to blow air by using a reverse valve, the air inlet side of the reverse valve needs to be small. By making the mouth small, it becomes easy to increase the pressure in accordance with the size of the child's mouth, and air can be smoothly introduced without blowing hard. This air blow-in check valve is an auxiliary means when the amount of gas released from the high-pressure gas holding part is insufficient due to gas leakage or the like.

    The “radar reflector” of the eleventh embodiment has a prismatic shape. When the reflecting plate means of the prismatic radar reflecting portion is formed in a lattice shape, it is desirable that the vertical direction surface of the reflecting plate means is substantially rectangular and arranged on the diagonal line of the prismatic cross section. Further, the plane direction surface of the reflector means is substantially square. The radar reflecting portion has an effect that the area of the reflecting plate means can be increased with respect to the volume of the prismatic portion by the above method. However, since the pressure receiving surface with respect to the wind becomes large, the shape is disadvantageous for the wind. In addition, since the corners of the prisms are easy to concentrate in terms of shape, the reflector means to be installed inscribed should avoid the corners and be inscribed with the reflector reflecting means and the inner wall surface of the radar reflector. There is also a case of letting. In addition, when the radar reflecting portion is square, the internal pressure of the gas is less likely to flow even though the surfaces are gathered at the corners and the rigidity is high, so that it is difficult to form a complete prism. For this reason, it is desirable that the prism-shaped radar reflecting portion has a rounded corner.

    <Effect of Embodiment 11>

    The “radar reflector” of the twelfth embodiment is spherical. This spherical shape means a substantially spherical shape. It is desirable that the reflector means substantially inscribed in the spherical radar reflector is substantially circular. When the radar reflection part is spherical, since the pressure acts uniformly on the outer surface of the radar reflection part, the radar reflection part is sufficiently expanded, and the inscribed reflector means is fully expanded in an orthogonal manner. This is performed more reliably than the radar reflector having another shape. Further, since the wind pressure coefficient with respect to the found area is small, there is an effect that the wind pressure is smaller than that in the tenth or eleventh embodiment.

    <Effect of Embodiment 12>

  Since the basic function is common to any one of the first to thirteenth embodiments with respect to the floating ring main body portion, the radar reflecting portion, the support column portion, the compressed gas holding portion, and the compressed gas switch portion, the detailed description is omitted. Description is omitted.

  The “light emitting part” emits light and is disposed on the uppermost part of the reflecting part. It is preferable that the light emitting portion is small and light and has a small size that is not bulky even when folded. In addition, a low-power consumption high-intensity light-emitting diode (LED), a discharge tube (flashlight), or an EL light-emitting element may be used for the light-emitting portion. As the driving power source, a combination of a storage battery and a solar battery may be used. These combinations can be lit for a long time. In addition, the light emitting unit can be turned on automatically or manually. The automatic lighting may be performed by incorporating a circuit for monitoring the illuminance of the surroundings with the power generation voltage of the solar cell, the phototransistor, or the CDS in the lighting circuit of the light emitting unit. Manual lighting may be a system that uses a magnetic sensor such as a hall element or a reed switch and a magnet, performs lighting without contact, and does not expose the switches to the outside. Thereby, corrosion by the water | moisture content of switches etc. can be suppressed and the reliability and lifetime of a folding storage type floating ring can be improved. It is also conceivable to use a fuel cell as a power source. The fuel cell oxygen can be obtained from the atmosphere, and hydrogen can be used in the high-pressure gas cylinder.

  In addition to the above, a fluorescent paint may be applied to the radar reflecting portion. Alternatively, the fluorescent paint may be applied to a part other than the radar reflecting part, that is, a support part, a floating ring body part, and the like. When searching with a flashlight or a searchlight at night, the fluorescent paint is emitted by those lights, and the search becomes easy.
