BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a throwing life preserver for rescue of a drowned person, and more particularly, to a throwing life preserver provided with a life tube provided to a drowner after a predetermined time.

In the case of the learner, it is often found that they are already in an emergency, so it is important to secure safety quickly. However, there is a risk that the drowner drowns while approaching the drowner, and it is very dangerous for the rescuer to jump directly into the water to rescue the drowner. Thus, conventionally, a method of throwing a life tube to a drowner has been used for remote rescue.

However, in the conventional method of throwing the life tube, since the life tube has a circular shape, there is a problem that it is very difficult to throw far away unless an experienced rescuer.

In addition, in the case of rescue boats, in order to store a large number of life tubes in a limited space, the life tubes themselves are reduced to a flat shape, but this inevitably decreases buoyancy. There was a problem that it is difficult to secure.

On the other hand, as a kind of conventional grenade, there is a delayed explosion type grenade which automatically explodes when a certain time elapses after throwing.

An object of the present invention is to provide a lifesaving device of a type that is easy to throw and store, and to automatically provide a lifesaving tube to a learner after a predetermined time after throwing.

When the other end of the body portion 12 is connected to the connecting line 125, it is possible to recover after throwing out the device 1, and furthermore, the connecting line 125 passes through the inner cavity to the life tube 100 When connected to the lifesaving tube 100 can be pulled with the lifesaving tube, so that the drowner can be rescued from the remote control. In addition, the other end of the body portion 12 may be formed with a handle portion 121 having a groove so as to increase the frictional force during throwing to be easily held in the hand.

Head 10 is provided with life-saving tube 100 is gas. Life-saving tube 100 is preferably rolled in a gas-free form in order to reduce the volume is placed in the head portion (100). However, the dried life-saving tube 100 shown in FIG. 1 is merely one embodiment, and it is also possible to crush and fix the head to reduce the volume. The material of the life preserver 100 is rubber or PVC material, for example.

In a preferred embodiment, the head portion 10 may be provided with a fixing line to fix the life tube 100 when throwing. The fixing line is preferably broken by the pressure when the life tube 100 is expanded. In FIG. 1, a total of two fixing lines secure the life tube 100 to the head 10. When the life tube 100 is inflated, four fixing lines are connected to the head 10. The fixing line may be configured to break at three or less fixing points of the fixing points. In this case, since the fixing line is not broken at every fixing point, there is an advantage in that the fixing line can be recycled.

Life-saving tube 100 may be a donut form or a cylindrical form inflated by the gas enters. Although the case of the donut type is common, it is more preferable as the structural form for many drowners because a cylindrical life tube has a larger area.

In a preferred embodiment, the head portion 10 has a lid portion 103 to protect the internal configuration of the life tube 100, etc. from the external environment when not in an emergency situation. The lid 103 is preferably removed before throwing.

Hereinafter, a gas storage unit 1007 and a gas injection method for supplying gas to the life tube 100 will be described with reference to FIG. 2.

Body portion 12 has a gas reservoir 1007 in its interior pupil. The gas reservoir 1007 uses a compound such as sodium azide (NaN ₃ ), which is used to inflate the air bag, to automatically supply air (nitrogen) to the life tube 100 after a predetermined time after throwing. Supply in a short time. In more detail, the gas storage unit 1007 is connected to a delay unit 2001 to be described later, and when a trigger signal is transmitted after a predetermined time has elapsed by the delay unit 2001, the gas storage unit 1007 is stored in the gas storage unit 1007. The igniter is activated to produce nitrogen. At this time, the rate of decomposition of sodium azide into nitrogen and sodium can be increased by reacting iron oxide (Fe ₂ O ₃ ) together. The gas reservoir 1007 is connected to the life tube and the tube 1003 to supply air to the life tube 100, the life tube 100 is provided with a nozzle 1001 to suck the air. The nozzle 1001 is a nozzle used for tires or play life tubes, and is preferably configured as a nozzle for exclusive use of suction so that it is not discharged once air is inhaled.

As a preferred embodiment, as shown in FIG. 2, the connecting cord 125 is connected to the connector 1005 of the life tube 100 through an internal cavity. In this case, the connection line 125 that the rescuer can pull is connected to the expanded life tube 100 itself after throwing, so that the drowned on the life tube 100 can be rescued remotely. In addition, the thrown life tube 100 may be recovered and recycled.

Hereinafter, referring to FIG. 3, a delayed trigger device 200 that causes the life tube 100 to expand after a predetermined time has passed after the throwing will be described. The delayed triggering device 200 uses a conventional delayed grenade method, and only the characteristic parts applied in the present invention will be described for brevity of the description.

Delay trigger device 200 is preferably formed in the handle portion 121 of the body portion (12). Delay trigger device 200 is a striker (2003) for hitting the trigger unit in the throwing to generate a trigger signal, trigger unit 2005 for transmitting the trigger signal generated by the striker to the trigger delay unit 2001, and trigger unit ( And a trigger delay unit 2001 for transmitting a trigger signal to the gas storage unit 1007 after a predetermined time elapses.

The striker 2003 is wound around the compressed spring 2004 to strike the trigger during throwing through the elastic force of the spring to generate a trigger signal. Since the spring 2004 of the striker 2003 is in a compressed state before throwing, if one end 20021 of the clip portion 2002 is not fixing one end of the striker 2003, it will be bounced toward the trigger by elastic force. As will be described later, one end of the clip portion 2002 fixes the striker 2003. However, since the clip portion 2002 releases the striker at the time of throwing, the striker 2003 causes the trigger portion to be released by elastic force. Hit.

The trigger delay unit 2001 is made of a fuming agent as a delay fuse and delays the trigger signal to the igniter of the gas storage unit 1007 for a time of about 2 to 5 seconds. The trigger delay time may be adjusted by adjusting the length of the trigger delay unit 2001. After the delay time has elapsed, the igniter of the gas reservoir 1007 receives a trigger signal and reacts iron oxide with sodium azide to supply nitrogen gas to the life tube.

In a more preferred embodiment, the handle portion 121, the handle clip portion 2002 is formed so as not to generate a trigger signal before throwing. The handle clip portion 2002 has one end 20021 connected to the striker 2003 so as to prevent the triggering force of the striker 2003 so as not to generate a trigger signal. Therefore, when the clip portion 2002 attached to the handle portion 121 is held by hand, the striker 2003 does not strike the percussion portion. However, since the striker 2003 places the clip portion 2002 by hand during throwing, the striker ( 2003) strikes the trigger and generates a trigger signal. Furthermore, the handle clip portion 2002 is provided with a safety pin 2006 for fixing the handle clip portion 2002 so as not to move even before throwing for safety. Therefore, when the safety pin is normally in a flower state, the striker 2003 does not hit the trigger part even when the clip portion 2002 is not held by hand, thereby ensuring safety during storage.

Hereinafter, a method of using the learner's lifesaving device according to the present invention will be described with reference to FIG. 4.

First, when the rescuer 300 finds the drowner 400, the protective cover 103 is removed and the handle 121 is held by hand. At this time, the clip portion 2002 of the handle portion 121 is held by hand to prevent a trigger from being thrown before throwing. Thereafter, the safety shell 2006 is removed and the lifesaving device 1 is thrown to the drowner 400. At the same time as the throwing, the clip portion 2002 is released to cause the striker 2003 to generate a trigger signal to the trigger delay portion 2001. After a predetermined time elapses after the throwing, nitrogen is automatically supplied from the gas reservoir 1007 to the life tube 100 in a short time in the vicinity of the drowner 400. When the drowner 400 catches the life preserver 100, the drowner 400 is pulled out to rescue the drowner 400 remotely by pulling the connecting line 125 connected to the life preserver tube 100.
