Further, in the upper part of the propulsion unit storage chamber 10 of FIG. 4, a rotary actuator 39 such as an electric motor is arranged side by side with the propulsion unit control unit 14.
The output shaft 39a of the rotary actuator 39 and the branch plate 36 of FIG. 6 are connected via links 40, 41 and a rod 42.

In the disengagement device 15 including the above-mentioned respective components, as shown by the solid line in FIG. 6, the hook 35 is rotated by the rotary actuator 39 through the branch plate 36, and the hook 35 and the holding metal fitting 32 are separated from each other. By holding the holding metal fitting 33 on the side of the tubular storage case 17 between the front and the back, the tubular storage case 17 storing the lifeboat 16 is connected to the rear end of the carrier 9. Then, the rotary actuator 39 is rotated by remote control from the aircraft via the wireless transceiver 13, and the hooks 35 of FIG. 6 are connected via the links 40 and 41, the rod 42, the branch plate 36 and the rod 38. As shown by a phantom line, the tubular storage case 17 of FIG. 2 is configured to be detached from the carrier 9 by rotating the holding metal fitting 33 to a position where it is detached.

Furthermore, the lifesaving boat 16 is stored in the tubular storage case 17 in a folded state, and inside the air storage container 16 is an air cylinder 4 shown in FIG. 7 as an example of a gas cylinder.
3 is built in. Discharge port 4 of this air cylinder 43
A pin 44 is attached to the 3a so as to be able to move forward and backward, and between the swing arm 45 that moves the pin 44 in the advancing direction and the branch plate 36 of the detaching device 15, a valve-opening actuation rope 46 is provided.

As a result, the lifeboat 16 expands rapidly and expands.

The altitude sensor 8 shown in FIG. 1 includes a two-conductor wire 48 electrically connected to the rocket igniter 7 and the two wires 48.
An electrode switch 49 connected to the lower end of the lead wire 48 of the core,
It has a weight 50 attached to the upper part of the electrode switch 49 and hanging the conducting wire 48. The electrode switch 4
9 conducts when it comes into contact with the sea surface, and the above-mentioned two-conductor wire 48
And the ignition circuit formed by the circuit in the rocket igniter 7 is closed, and the rocket igniter 7 is ignited. In the altitude sensor 8 having such a configuration, the conductor 4
The hanging length of 8 determines the altitude at which the rocket 6 is ignited, and is appropriately set according to the mass of the rescue device and the descent speed of the parachute 1.

Next, the operation of the aircraft drop type indirect rescue device having the above configuration will be described. First, as shown in FIG. 8, when the entire rescue device is dropped from the aircraft 60 in the vicinity of the marine casualty A, the setting of the parachute 1 itself is performed with the inductive rescue device 4 hanging below the parachute 1. It descends at a speed. When the electrode switch 49 of the altitude sensor 8 comes into contact with the sea surface after descending to near the sea surface, the ignition circuit is closed and the rocket ignition device 7 operates, and the ignition signal is transmitted to the ignition unit of the rocket 6. Rocket 6 is jetted.

The jetting of the rocket 6 slows down the descent speed, so that the entire device lands at low speed on the sea surface, and the impact acting on the rescue device 4 is sufficiently mitigated. At the time of landing, a reaction force acts on the rescue device 4 from the sea surface.
Utilizing this reaction force, the rescue device holding mechanism 5 of FIG. 1 is detached as described above, whereby the rescue device 4 is automatically separated from the parachute 1 and the dropping device main body 3.

When the rescue device 4 is separated from the parachute 1 and the dropping device body 3, the rocket 6 is still in the operating state, and therefore the load of the rescue device 4 is released and the parachute 1 and the dropping device are lightened. The device body 3 is
It receives the propulsive force of the rocket 6 and is launched upward, and is separated far away. This prevents entanglement between the parachute 1 and the rescue device. On the other hand, the separated rescue device 4 floats above the sea.

In this way, the rescue device 4 levitated above the sea is
The wireless transmitter / receiver 13 receives a wireless signal from the aircraft 60 through the antenna 19, and first causes the propulsion machine controller 14 to extend the linear motion actuator 30 in the lifting mechanism 12. With the extension operation of the linear motion actuator 30, the bending link 31 is bent as shown by the phantom line in FIG. 5, and the rotary shaft 22 is rotated around its axis. As a result, the propulsion unit 11 is displaced in the direction of the arrow X in FIG. At this time, the lower door 2 of the propulsion unit storage room 10
6 interlocks with the displacement of the propulsion unit 11 via the support arm 11a and the link 28 and opens downward. On the other hand, the upper door 24 is pushed out by the propulsion unit 11 against the urging force of the spring 27, opens outward, and then returns to its original position by the elastic force of the spring 27 when the propulsion unit 11 projects to the outside. Automatically returns.

As described above, the propulsion device 11 is deployed outside after the rescue device 4 is levitated above the sea, and is stored inside the rescue device 4 at the time of landing. Therefore, the propulsion device 11 may be damaged by the impact at the time of landing. Absent.

Next, while looking at the radar scope 61 installed in the aircraft 60 of FIG. 8 and displaying the position of the victim A, the fall position of the rescue device 4, the wind direction, etc., a radio signal is transmitted from the aircraft 60 side. To control the rotation (forward rotation, reverse rotation, rotation speed, etc.) of the propulsion unit 11 via the propulsion unit control unit 14 to bring the rescue device 4 closer to the victim A.

When the rescue device 4 approaches the victim A and sends instructions wirelessly from the side of the aircraft 60, the instruction contents are received by the wireless transceiver 13 of FIG. 2 and then transmitted via the transmitter / receiver 20. It becomes a voice and is transmitted to the victim A. Also, the words of the victim A are transmitted to the aircraft 60 side of FIG. 8 through the transmitter / receiver 20, and the situation of the victim A can be grasped on the aircraft 60 side.

Next, when a lifebuoy disengagement command signal is sent from the aircraft 60, the rotary actuator 39 in the disengagement device 15 of FIG. 4 rotates, causing the links 40, 41, rod 42, branch plate 36 and rod 38 of FIG. Via each hook 35, as shown by the phantom line in FIG. 6, the hook 35 is rotated to a position where it is detached from the holding metal fitting 33. As a result, the cylindrical storage case 17 separates from the carrier 9 and becomes free. This allows the front opening 17 of the storage case 17 of FIG.
When a is released, the lifeboat 16 can pop out.

At this time, in conjunction with the rotation of the branch plate 36, that is, in conjunction with the detaching operation of the detaching device 15, FIG.
8 is pulled to open the air cylinder 43, and with this, high-pressure air is ejected from the air cylinder 43 into the lifesaving boat 16 and, as shown in FIG.
Expands rapidly and expands. The victim A boarded the expanded lifeboat 16 and waited for rescue.

In the above embodiment, the rescue device is dropped near the victim by using the aircraft 60. However, the rescue device may be dropped by a ship. In that case, the parachute 1 and the rocket 6 are not required. In the case of the type of dropping from a ship, it is possible to use wired remote control instead of wireless remote control as in the above embodiment.

Further, as the rescue kit, in the above-mentioned embodiment, the rapid expansion type lifeboat was used for explanation.
Other than that, any boat such as a fixed boat can be used as long as it can temporarily rescue the victim.

Further, in the above-described embodiment, the storage case 17 has the front opening 17a opened by being detached from the carrier 9, but unlike this, it remains connected to the carrier 9 or is detached therefrom. In this state, the lifesaving boat 16 may be taken out by opening the upper part or the rear part of the storage case 17.

[0034]

As described above, according to the first aspect of the invention, the propulsion device is expanded to the outside of the carrier by remote control while the dropped carrier is levitated above the water.
It is possible to control the propulsion of the propulsion device by remote control, and the entire rescue device can be quickly brought close to the victim. Further, the rescue kit can be taken out of the carrier to perform rescue for the victim by remote control when reaching the vicinity of the victim. Therefore, even if the drop position on the water slightly shifts, the rescue kit should be brought close to the victim in a swift and reliable manner, regardless of wind strength and wind direction, and the reliability of rescue activities should be significantly improved. You can

Further, according to the second aspect of the invention, the lifeboat can be rapidly expanded by the high pressure gas ejected from the gas cylinder in conjunction with the opening operation of the storage case, so that the victim can be assured. I can rescue.
