[0007] (Embodiment 1) Figure 1 is a perspective view showing a float device according to Embodiment 1 of the present invention. This float device 100 consists of a band portion 1 for bundling and securing multiple PET bottles, and a bracelet 2 provided on a part of the band portion 1 for putting the arm through. The band portion 1 is a band woven from nylon fibers and is selected to be water-resistant. The bracelet 2 has a diameter large enough to fit a man's upper arm. A buckle 3 is provided on a part of the band portion 1. The buckle 3 is preferably structured so that the band is tightened by pulling the edge 1a of the band.

[0008] It is preferable to bundle three or more plastic bottles together. As shown in Figure 2, this float device 100 is used by attaching it to a plastic bottle P in the event of a disaster. There are no restrictions on the number or shape of the plastic bottles P; as long as they can be secured by the band part 1, it is fine. Because the float can be easily constructed, it is easy to respond quickly in the event of a sudden disaster. Furthermore, it can be made compact and portable under normal circumstances.

[0009] Furthermore, as shown in Figure 3, a life-saving device can be made using a string 20 with a female threaded portion 21 at its end that can be screwed onto the male threaded portion P1 of the lid of a PET bottle P. The female threaded portion 21 at the end is designed to fit the male threaded portion P1 of a typical PET bottle P. A seal is provided inside the female threaded portion 21 (not shown). This seals the air inside the PET bottle P.

[0010] Also, as shown in Fig. 4, an annular portion 31 that can be wound around and fixed near the drinking mouth may be provided at the tip of the string 30 so as to engage with the flange portion P2 of the drinking mouth of the PET bottle P. A buckle 32 for tightening the string 30 is provided on the annular portion 31. In the case of this configuration, the original lid of the PET bottle P can be used. In this way, the string 30 can be easily attached to the PET bottle P, so that the victim who throws and catches the PET bottle P can be pulled. Also, the victim can also hook the PET bottle P on a fixed structure or the like by flowing the PET bottle P on the water surface with the string 30, and in that case, the string 30 can be wound in by hand to reach the shore.

[0011] As shown in Fig. 5, a radio control device 50 that can propel on the water surface by a screw may also be provided on the PET bottle P. Fig. 6(a) is a configuration diagram showing the radio control device. It has a hollow cylindrical main body 52 that is inserted into and fixed inside the PET bottle P near the bottom from the rear opening 51, a power source 53 such as a secondary battery provided inside the main body 52, a receiving circuit and other electronic circuits 54, a servo device 55 including a drive circuit and the like, and a motor 56, a screw 57 provided on the rotation shaft of the motor 56, and a rudder 58 interlocked with the servo device 55. A water intake 59 is provided around the screw 57 in the main body 52. The power source and the like are concentratedly arranged in a part of the main body 52 to form a center of gravity in one direction. Incidentally, the radio control device 50 may be provided on one of the bundled PET bottles P as shown in Fig. 2.

[0012] The electronic circuit 54 includes a receiver, a speed control circuit, an electronic speed control circuit for a servo motor, etc. The operating device 60 is a general one composed of a transmitter 61, an operating portion 62 such as a lever, a power source 63, etc.

[0013] In the float device 101 shown in the figure, the RC device 50 can be operated with the PET bottle P floating on the water surface, and the PET bottle P can be quickly delivered to the vicinity of the victim. Since the PET bottle P, which is a floating object, can be delivered to the victim before the rescue team arrives, drowning of the victim can be prevented. Also, items necessary for rescue may be pre-stored inside the PET bottle P. Further, since a plurality of PET bottles P can be sent, if rescue goods are placed in some of them, the emergency rescue ability will be further enhanced.

[0014] Items to be stored inside may be a portable information device, an LED light, or a life jacket. In particular, if the life jacket is structured to be folded and stored in a tubular state and inflated, it can be easily stored in the PET bottle P. It is preferable to store these between the main body 52 and the PET bottle P. This is because the PET bottle P can continue to be used as a floating object. In that case, as shown in FIG. 6(b), a storage portion 65 is provided in front of the main body 52 (opposite side to the screw). The storage portion 65 is a separate compartment from the compartment with a built-in motor or the like, and the front wall surface 66 is made of a thin material that is easy to break. By making it a thin material, the victim who has obtained the PET bottle P can remove the main body 52 from the PET bottle P at the scene and break the wall surface 66. By breaking the wall surface 66, the stored items inside can be taken out. Thereby, the victim can be quickly saved.

[0015] (Embodiment 2) FIG. 7 is a configuration diagram showing a float device according to Embodiment 2 of the present invention. As shown in the figure, this float device 200 is configured such that a main body 201 made of a boat-shaped float hollow body using the material of a PET bottle is molded, and an RC device 250 is provided at the rear. Also, an LED light 202 can be equipped on the main body 201. This float device 200 can have a transparent main body 201 and an LED light can also be arranged inside (not shown).

[0016] The LED light 202 is directly connected to the power supply of the radio control device 250 via a rectifier and resistor, and operates while the switch is on. Alternatively, a flashing circuit may be added to make the LED light 202 flash. The radio control device 250 used has the same configuration as in Embodiment 1 described above. Because the main body 201 of this float device 200 is boat-shaped, it is easy to travel at high speed on the water. Also, because its posture is stable, the main body 201 is easy to operate. Therefore, it is possible to quickly rescue victims.

[0017] Furthermore, as shown in Figure 8, the main body 201 is equipped with a storage compartment 260 on its side that resembles a plastic bottle, and beverages are stored in this storage compartment 260. The plastic bottle shape was chosen so that disaster victims, who may be in a state of distress, can intuitively understand what it is. For example, if a disaster victim finds this float device 200 on the water and sees that it has a plastic bottle-like attachment, they can consider using that part as a float, and if there is a lid, they can infer that it is okay to open that part. The storage compartment 260 may be made of PET material, be a simple cylindrical shape, and have a lid that can seal the inside. Items stored inside include, as mentioned above, portable information devices, LED lights, life jackets, etc.

[0018] The LED light 202, by being a bright LED light 202, allows the float device 200 to be seen from a distance. It is particularly suitable for rescue operations at night. The LED light 202 allows the victim who has secured the float device 200 on the water at night to use the light, thereby providing reassurance. It is also convenient for taking out food being carried at the same time. Furthermore, the illumination of the LED light 202 makes it easier for rescuers to determine the victim's location at night. The LED light 202 may also be configured to change its illumination mode based on the victim's actions, such as automatically changing the color of the light or changing from flashing to steady. In this case, rescuers can easily confirm the victim's presence based on the state of the light source. That is, if the light changes from flashing to steady or the color changes, it can be confirmed from a distance that the victim is conscious.

[0019] In addition to the LED light 202, reflective tape 203 may be attached to a part of the main body 201. In this case, it becomes easier to spot victims on the water by shining a searchlight from a ship.

[0020] (Embodiment 3) Figures 9 to 11 are configuration diagrams showing a float device according to Embodiment 3 of the present invention. The float device 300 has a hollow, ring-shaped float body with a sharp-angled or chamfered tip to facilitate forward movement. The shape is designed to allow water to drain quickly in order to reach the victim as soon as possible. A radio control device 350 is also provided on the body 301 of the float device 300. The configuration of the radio control device 350 is the same as in Embodiment 1.

[0021] The float device 300 shown in Figure 9 is a triangular ring. The ring shape allows it to be used as a life preserver upon reaching a disaster victim. The triangular shape with a pointed tip provides both speed and stability, making it easier to control via radio. Alternatively, as shown in Figure 10, the entire device can be a rhombic ring. In this case, it can also be used as a life preserver, and its stable posture allows for quick delivery of the float device 300 to the disaster victim. Figure 11 shows an O-shape; in this case, rounded corners provide stability, reducing lateral swaying, especially in poor water conditions. This makes it easier to control via radio.

[0022] Furthermore, a handle may be provided on the body of the float device shown in the above embodiment. Figure 12 is a perspective view of a boat-shaped float device 200 with a handle 350, and Figure 13 is a perspective view of a triangular ring float device 300 with a handle 360. The handle 360 ​​makes it easier for the victim to hold the body while floating on the water surface, thus preventing physical exhaustion while floating on the water surface. Figure 14 shows a mug-shaped float body 351 with a handle 360. All of the floats are equipped with the radio control device 350 described in Embodiment 1 above. The float body of this float device may also be made of polystyrene foam (not shown).

[0023] (Embodiment 4) Figure 15 is a perspective view showing a float device according to Embodiment 4 of the present invention. This float device is the same as the float device of Embodiment 1, but with the PET bottle replaced by a polystyrene cylindrical body 70. The other components are the same as in Embodiment 1. The polystyrene cylindrical body 70 is a component of the float device, and the number can be selected as needed. A radio control device 50 as described above may also be attached to the cylindrical body 70 (not shown).

[0024] Figure 16 is a perspective view showing another float device according to Embodiment 4 of the present invention. This float device is a modified version of the float device of Embodiment 2, in which the hollow float body is replaced with a polystyrene foam float 270. The other configurations are the same as those of Embodiment 2.

[0025] In either case, the same effects and advantages as those of Embodiments 1 and 2 described above will be achieved.

[0026] (Embodiment 5) Figure 17 is an explanatory diagram showing how to use the float device according to Embodiment 5 of the present invention. The float device according to the present invention is suspended (or stored) by a remotely controlled aircraft such as a drone, and can be detached remotely. For example, the float device 100 is suspended from the drone D by a string. The string D1 is fixed to a temporary fixing part at the base of the drone D, and the string D1 can be detached from the body of the drone D by remotely releasing the hold. The structure of the temporary fixing and the remote operation can be known configurations.

[0027] The float device 100 is lightweight because it is made of a hollow body. Therefore, it can be easily transported by being suspended from a drone D. The operator moves the drone D to the location of the victim, and then detaches the rope D1 near the victim, dropping the float device 100 near the victim. This allows the float device 100 to be quickly provided to the victim. Alternatively, the float device 100 may be carried to the victim, and the victim may detach the float device 100 by pulling the rope D1.

[0028] Alternatively, other float devices 200 and 300 can be suspended by drone D (not shown in the diagram). In this case as well, the float devices 200 and 300 can be quickly provided to disaster victims using the same operation as described above.

[0029] (Embodiment 6) Alternatively, explosives may be placed inside the PET bottle P and the main body 201 of the hollow float for use in civil engineering works, etc. As shown in Figure 18, this float device 600 has dynamite 80 loaded inside the PET bottle P, which is the hollow float, and a detonator 81 inserted into the dynamite 80. The detonator 81 is electrically connected to the electronic circuit of a radio control device 50 provided at the end of the PET bottle P. A predetermined current is supplied from this electronic circuit according to the instructions from the operating device 60. This detonates the dynamite 80. The radio control device 50 has the same configuration as shown in Embodiment 1 above.

[0030] In this float device 600, the radio control device 50 is operated by the control device 60, and while floating due to the buoyancy of the PET bottle P, it is moved to a predetermined location by the thrust of the radio control device 50. At that moment, the control device 60 operates the electronic circuit 54 to supply current to the detonator 81, causing it to explode. It can be used for blowing up bridge girders, obstacles on the water surface, etc. Although not shown in the figures, dynamite 80 can also be mounted on the float device described in Embodiments 2 to 4.

[0031] Furthermore, in embodiments 1 to 5 described above, a camera can be attached to the radio control device 50, and the camera data can be transmitted to the operating device 60. The camera image may be a video or a series of still images. The user may have the camera image displayed on a display unit provided on the operating device 60 and operate the device while viewing the image.

[0032] Furthermore, the above-mentioned float device becomes a life-saving float device if it can be used for the purpose of saving a life. [Explanation of Symbols]
