[0001] A PORTABLE LIFESAVING DEVICE USED THROWING [0002]

The present invention relates to a portable trowel-type life-saving device capable of easily carrying and throwing toward a survivor who has fallen into the water when an underwater safety accident occurs, and at the same time, the tube can be expanded to construct a survivor through a tube.

More particularly, the present invention relates to a portable trolling-type life-saving apparatus in which a portable trolley-type life-saving apparatus is simple to carry and which expands a tube at the same time as throwing, comprising: a compression gas cylinder (100) A body portion 200 formed to be capable of being gripped and having a connection 201 and an outlet 202 connected to the inside of the side portion; And a tube unit 300 connected to the discharge port 202 and containing the compressed gas container and expanding by a compressed gas flowing through the body unit 200. The body unit 200 includes: A first gas moving pipe 210 through which the compressed gas introduced from the compressed gas cylinder 100 moves through the connector 201; A safety pin 220 penetrating the first gas moving pipe 210 and regulating the opening and closing of the first gas moving pipe 210 through an operation; Timer means (230), one end of which is connected to the first gas moving pipe, for delaying the movement of the compressed gas introduced through the first gas moving pipe; A pushing member 240 passing through one end of the first gas moving pipe 210 and controlling opening and closing of the timer means 230 through movement according to an external force; And a second gas flow pipe (250) having one end connected to one side of the timer means (230) and the other end connected to the discharge port (202) so that the compressed gas passing through the timer means (230) Wherein said portable lifting lifter comprises:

Recently, as more people are enjoying underwater activities such as water sports and leisure sports in summer, interest in underwater safety accidents that may arise is increasing.

Particularly, since water safety accidents do not develop into human accidents only after rescue activities occur in a short time after an accident, rescue equipment should always be provided in the vicinity of water sports and leisure sports.

Generally, lifesaving tubes are widely used as life-saving devices. Lifting tubes connected to ropes are provided on lifting means such as ships. When a safety accident occurs during a water dip in a river or sea, accident detectors or safety personnel Let this life-saving tube be thrown to the old egg to rescue the survivor.

However, since there is a limit to the distance that a life-saving tube can be conveyed and the inside of the life-tube is filled with air due to the characteristics of the life-time tube, the range of transmission is shortened due to winds during thrusting and it is difficult to throw in a desired direction It is inconvenient that it is difficult.

In addition, since it is rarely provided due to the volume occupied by the life-saving tube, and it is inconvenient to carry it personally when the air is filled, there is a possibility that the safety life is not provided near the safety accident or the rescue operation time may increase. Research has been conducted on lifesaving tubes that are easy to carry and have a wide thumping range.

On the other hand, portable lifesaving tubes (hereinafter, referred to as 'prior art 1') are described in Japanese Patent Laid-Open Publication No. 10-2011-0087474 in connection with lifesaving tubes which are portable and can be thrown to the old eggs, No. 10-1174621 discloses a throwing lifesaving tube ball (hereinafter referred to as 'Prior Art 2').

The present invention relates to a portable lifesaving tube, and more particularly, to a portable lifesaving tube having a body having a predetermined space, a gas generator accommodated in the body and having a mixture of sodium azide and iron oxide, A combustion chamber connected to the gas generator for inducing the gas generated in the gas generator to be completely burned, a first end connected to the combustion chamber and a second end connected to the tube, And a tube connected to the flame retarding unit and expanded by the gas flowing through the flame retardant unit.

Prior Art 1 provides a portable lifesaving tube which is inexpensive, portable and easy to use and has a high possibility of reshaping the tube due to the tube being slowly inflated.

However, since the prior art 1 is a chemical reaction in which a gas is generated and the tube expands, a chemical reaction does not occur in the case of a manufacturing process or a storage problem, so that the tube may not expand.

Prior Art 2 relates to a life-saving tube ball, and more particularly, to a lifesaving tube that is placed in a spherical ball and is quickly thrown to a person who has fallen into the water, In order to make it look like a sphere, spheres are formed in three equal parts, and both semicircles incised on one part of the third part are formed by hinges on both sides of the center part, A lifesaving tube ball that is an outer sphere that, when lifted, forms a perfect spherical shape; A compressed air tank portion inside the outer sphere; A life tube portion which is directly connected to the compressed air tank portion and is resistant to impact and is tough; A water detecting sensor unit having a center of gravity formed on the outer sphere as a central portion of a sphere and forming a water sensor on a bottom center of gravity by a movement effect like a grasshopper; A safety hook pin connected to a wire for removing a transparent film blocking water from the outer surface of the water sensor; The safety pin is pulled out and removed to remove the transparent film of the water detection sensor. When the life tube ball is thrown into the water, the operation of the water detection sensor causes air to come into the life tube ball, The sphere of the life tube ball is opened, and the compressed air completely cushions air into the life tube and is completed as a life tube. The life tube is delivered promptly to the person who wants to save the life, and the life is saved. By lifting the life tube, it is possible to prevent time, material and human loss, and it can be used by anyone and can be recycled by replacement of several parts.

However, in the prior art 2, since the water sensor senses water, the air is buffered in the tube. Due to the nature of the place where the water safety accident occurs, it is very likely that unnecessary operation is likely to occur because water can be easily contacted from the periphery. Further, when an abnormality or failure of the water sensor occurs, it is difficult to check it from time to time, and there is a risk of throwing the failed life-throwing tube ball.

Therefore, it is possible to operate only by the user's manipulation rather than using a chemical reaction or using a water sensor, and the life tube is inflated at the same time as throwing, and the rescue tube thrown by the rescuer reaches the position of the survivor It is necessary to develop a technique capable of controlling the tube expansion rate.

(Prior Art 1) Published Japanese Patent Application No. 10-2011-0087474 (Aug. 23, 2011) (Prior Art 2) Patent Registration No. 10-1174621 (Aug. 22, 2012)

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents And variations are possible.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

1 and 2 of the accompanying drawings, there is shown a life preserver in which a compressed gas container 100 for storing a compressed gas therein and a compression gas container 100 having one side thereof are combined with the compressed gas container 100 and can be grasped And a tube unit 300 connected to one side of the body part 200 and having a compressed gas cylinder 100 therein.

In this life preserver, the compressed gas is moved to the tube means 300 through the body portion 200 through the operation of the body portion 200 connected to the compressed gas container 100, and the tube means 300 is expanded.

At this time, since the compressed gas cylinder 100 is not exposed to the outside, the pressure gas cylinder is prevented from being separated from the body portion 200 by the external force, and even if the compressed gas is leaked, the compressed gas is introduced into the tube means 300 There is an advantage.

Referring to FIG. 2 (a), since the compressed gas is not present in the tube means 300 before the use, the compressed tube means 300 may be exposed to the outside, which may make installation and storage of the life-saving device inconvenient.

2 (b), a case 400 for arranging and storing the compressed tube means 300 is additionally provided so that the tube means 300 can be arranged. Such a case 400 can prevent damage to the tube means 300 such as tearing, and is easy to store and improve portability.

Hereinafter, a configuration of a portable lifting lifter according to the present invention and an embodiment thereof will be described with reference to FIGS. 3 to 7 of the accompanying drawings.

Example 1. Through connector 201 As the body part 200 And the inflated compressed gas is discharged through the discharge port to inflate the tube means (300).

FIG. 3 shows an external configuration of a body part constituting a portable lifting lifter according to a first embodiment of the present invention. FIG. 4 shows a configuration of a body part according to the first embodiment of the present invention, FIG. 6 is a sectional view of a taper piston according to a first embodiment of the present invention. FIG. 6 is a sectional view of a taper piston according to a first embodiment of the present invention. Fig.

The body portion 200 has a connecting hole 201 formed at one side thereof to be connected to the compressed gas container 100 and the compressed gas moves along the inside of the body portion 200.

The compressed gas moves along the inside of the body portion 200, and then discharges the compressed gas through the discharge port 202 formed at one side. The outlet 202 is also connected to the tube means 300 so that the tube means 300 is expanded through the compressed gas discharged through the outlet 202. In addition, the connector 201 and the outlet 202 are O-ring-treated on the outer surface so that the compressed gas does not leak.

The body portion 200 includes a first gas moving pipe 210, a safety pin 220, a timer means 230, a pressing member 240 and a second gas moving pipe 250.

The first gas moving pipe 210 is connected to the connecting pipe 201 and serves as a passage through which the compressed gas introduced from the compressed gas container 100 flows through the connecting pipe 201.

At this time, the body part 200 may further include a timer valve 211 that is drawn into the first gas moving pipe 210 at a portion where the first gas moving pipe 210 is connected to the outside.

The timer valve 211 does not close the first gas moving pipe 210 but serves to slow the movement of the compressed gas by reducing the inner width of the first gas moving pipe 210 to which the compressed gas moves ) Reference). A screw thread formed along the outer peripheral surface of the upper end of the timer valve 211 may protrude out of the body portion 200 and a screw groove corresponding to the thread may be formed in the body portion 200 where the upper end of the timer valve 211 is positioned .

Accordingly, the inner width of the first gas moving pipe 210 is increased by rotating the upper end of the timer valve 211 protruding out of the body 200, and the movement of the compressed gas moving along the first gas moving pipe 210 is accelerated And the expansion speed of the tube means 300 can be adjusted through the timer valve 211 (see FIG. 5 (b)).

At this time, a horizontal spring 211a is provided on the outer peripheral surface of the timer valve 211. The horizontal spring 211a contracts and expands in the horizontal direction to prevent the timer valve 211 from being repelled outward, 211 are in contact with the inner surface of the drawn-in body portion 200 to fix the timer valve 211.

The safety pin 220 passes through the first gas moving pipe 210 and regulates the opening and closing of the first gas moving pipe 210 through movement in the outward direction.

The upper end of the safety pin 220 protrudes outward from the body and is exposed to the outside. The upper end of the safety pin 220 may be formed with a ring 220a that can be held by the user.

The compressed gas moves to the first gas moving pipe 210 connected to the connecting pipe 201. However, the safety pin 220 passing through the first gas moving pipe 210 closes the first gas moving pipe 210, The timer means 230 can not be moved (see Fig. 6 (a)).

At this time, the safety pin 220 is provided with a stopper 220b on the outer circumferential surface corresponding to the first gas moving pipe 210 so as to prevent the compressed gas introduced through the first gas moving pipe 210 from flowing into the timer means 230, Prevent gas from moving.

If the lifesaving device must be operated due to a safety accident, if the safety pin 220 is pulled in the protruding direction of the safety pin 220 by holding the hook of the safety pin 220, the safety pin 220 moves in the outward direction, (See Fig. 5 (b)). Accordingly, the compressed gas moves to the timer means 230 along the first gas moving pipe 210 opened by the movement of the safety pin 220.

The timer means 230 is connected to the first gas moving pipe 231 at one end and serves to delay the movement of the compressed gas introduced through the first gas moving pipe 230.

On the other hand, the compressed gas traveling along the first gas moving pipe 210 may not have enough hydraulic pressure to flow into the timer means 230 because the flow velocity is slow during the movement.

Accordingly, in the present invention, the expansion of the tube means 300 is prevented from occurring until the user throws the life-saving device, and the user is able to move the compressed gas to the tube means 300 while throwing the life- And a pushing member 240 which is a means for increasing the hydraulic pressure of the compressed gas and assisting the quick introduction of the compressed gas into the timer means 230 is formed.

The pushing member 240 penetrates one end of the first gas moving pipe 210 connected to the timer means 230 and regulates opening and closing of the timer means 230 through movement according to external force.

The pressing member 240 is formed at one end of the first gas moving pipe 210 to which the first gas moving pipe 210 and the timer means 230 are connected and the portion corresponding to the first gas moving pipe 210 has a width The width of the first gas moving pipe 210 is less than the width of the first gas moving pipe 210 and the width of the first gas moving pipe 210 does not correspond to the width of the first gas moving pipe 210.

A portion of the pushing member 240 is exposed to the outside of the body and a portion opposite to the exposed portion is connected to the spring so that when the exposed pushing member 240 is pushed, the pushing member 240 moves along the direction in which the spring is compressed do.

Meanwhile, it is possible to form the handle 241 connected to the body so that the pushing member 240 can not be separated from the body and the user can easily operate the pushing member 240.

The handle 241 moves along an axis connected to the body and a stopper 242 may be provided on the body to prevent unnecessary rotation of the handle 241. [ Accordingly, the user can press the push member 240 through the handle 241 to close the first gas moving pipe 210 before pulling the safety pin 220 to operate the life-saving device.

The user pushes the life-saving device through the pushing member 240 and the handle 241 and opens the first gas moving pipe 210 so that the tube means 300 is inflated. A detailed description thereof will be described with reference to the third and fourth embodiments described later.

The second gas moving pipe 250 has one end connected to the side of the timer means 230 so that the compressed gas having passed through the timer means 230 flows into the second gas moving pipe 250 and the other end is connected to the discharge port 202, Is moved to the tube means (300) through the outlet (202).

At this time, a taper pipe 260 is formed inside the second gas moving pipe 250, and a taper piston 261 corresponding to the shape of the inside of the taper pipe 260 is built in the taper pipe 260.

The taper piston 261 normally closes the second gas moving pipe 250 and moves through the compressed gas introduced into the second gas moving pipe 250 to open the second gas moving pipe 250.

At this time, when the taper piston 261 comes into contact with the inner surface of the taper pipe 260, the compressed gas can not flow in the moving direction of the taper piston 261, so that the taper piston 261 may not move smoothly. The taper piston 261 forms a projection 261a on the side corresponding to the second gas moving pipe 250 so that the compressed gas introduced into the taper pipe 260 can easily move the taper piston 261 7 (a)).

When the compressed gas moving along the second gas moving pipe 250 flows into the taper pipe 260, the taper piston 261 moves along the inner circumferential surface formed in the taper pipe 260, (250) is opened so that the compressed gas can be discharged to the discharge port along the second gas moving pipe (250) (see Fig. 7 (b)).

Through the above process, it is possible to prevent the case that the tube unit 300 is gradually expanded during reaching the spherical egg at the time of throwing, thereby preventing the previously inflated tube from reaching the spherical oocyte, &Lt; / RTI >

Meanwhile, when the compressed gas is moved through the body portion 200, the tube means 300 can be prevented from suddenly expanding. However, if the tube means 300 is operated to take a long time to move along the inside of the body portion 200, The expansion of the means 300 may be delayed.

Accordingly, in the present invention, a plurality of connection ports are formed on the side surface of the body portion 200 so that the compressed gas can be rapidly expanded to the tube means 300, so that the compressed gas can be moved from the compressed gas container 100.

Example 2. Plural Through the connector As the body part 200 And the inflated compressed gas is discharged through the discharge port to inflate the tube means (300).

According to the second embodiment, the connector 201 may include a first connector 201a and a second connector 201b.

The first connecting port 201a is connected to the first gas moving pipe 210 and is connected to the first gas moving pipe 210, the timer means 230, the second gas moving pipe 250 and the taper pipe 230 of the body part 200, And discharges the compressed gas to the discharge port through the discharge port 260.

The second connection port 201b is connected to the side surface of the taper pipe 260 so that the compressed gas existing in the compressed gas container 100 moves to the taper pipe 260 through the second connection port 201b and then moves to the discharge port do. At this time, there is a third gas moving pipe 270 connecting the side surface of the taper pipe 260 and the second connecting pipe 201. A check valve CV is formed in the third gas moving pipe 270, The compressed gas moving along the tapered pipe 270 can be moved to the tapered pipe 260.

At this time, the position where the taper pipe 260 and the third gas moving pipe 270 are connected should be located where the taper piston 231 is opened and closed according to the movement of the taper piston 231 (see FIG. 10A).

The compressed gas introduced through the second gas moving pipe 250 moves the taper piston 231 to open the second gas moving pipe 250 and the third gas moving pipe 270 is opened so that the compressed gas flows into the third gas And flows into the taper pipe 260 along the moving pipe 270.

The compressed gas flowing into the taper pipe 260 along the second and third gas moving pipes 270 is discharged to the tube means 300 through the discharge port along the opened second gas moving pipe 250 (B)).

Thus, the compressed gas can be rapidly transferred to the tube means 300 while forming the plurality of connectors 201, and the tube means 300 can be rapidly expanded.

The timer means 230 constituting the present invention may be composed of a cylinder chamber 280 or an expansion chamber 290.

Therefore, this technical matter will be described as a third embodiment and a fourth embodiment of the present invention.

Example 3. Timer means 230 The cylinder chamber 280 Made portable Throwing expression Life preserver

The operation of the cylinder chamber 280 according to the third embodiment will be described in detail with reference to FIG. 10 of the accompanying drawings.

Prior to explanation, it should be noted that the description overlapping with the first embodiment is omitted in the description of the third embodiment of the present invention.

Therefore, only the configuration, function and effect of the third embodiment, which is different from the first embodiment, can be described in the following description.

FIG. 10 illustrates an operation process of the cylinder chamber according to the third embodiment of the present invention.

10A, the first gas moving pipe 210 and the cylinder chamber 280 are connected to each other. One end of the first gas moving pipe 210 connected to the cylinder chamber 280 is connected to the first gas moving pipe 210, A pressing member 240 is formed.

At this time, a check valve CV is formed at one end of the first gas moving pipe 210 so that the compressed gas traveling along the first gas moving pipe 210 flows into the cylinder chamber 280 through the pushing member 240 And a check valve CV is formed at one end of the second gas moving pipe 250 connected to the side of the cylinder chamber 280 so that the compressed gas passing through the cylinder chamber 280 flows into the second gas moving pipe 250 Respectively.

The cylinder chamber 280 and the second gas moving pipe 250 are connected so that the compressed gas flowing into the cylinder chamber 280 does not remain in the cylinder chamber 280 but can move to the second gas moving pipe 250 And a check valve CV is provided at the position.

The user can press the push member 240 through the handle 241 to close the first gas moving pipe 210 before pulling the safety pin 220 to operate the life preserver.

The compressed gas is moved along the first gas moving pipe 210 when the safety pin 220 is pulled after the first gas moving pipe 210 is closed by moving the pressing member 240 through the handle 241, The compressed gas is closed by the pushing member 240 and remains in the first gas moving pipe 210 (see FIG. 10 (b)).

The pushing member 240 is moved through the elastic force of the spring connected to the pushing member 240 while the pressure applied to the handle 241 disappears. Through the movement of the pressing member 240, the compressed gas passes through the pressing member 240 having a smaller width than the first gas moving pipe 210 and flows into the cylinder chamber 280.

The compressed gas remaining in the first gas moving pipe 210 is suddenly introduced into the cylinder chamber 280 through the opening of the first gas moving pipe 210 due to the pushing member 240 to move the piston 281 10 (c)).

The piston 281 moves through the compressed gas introduced into the cylinder chamber 280 so that the inside of the cylinder chamber 280 and the second gas moving pipe 250 connected to the side of the cylinder chamber 280 are connected. The compressed gas flowing into the cylinder chamber 280 moves to the second gas moving pipe 250 connected to the side of the cylinder chamber 280 through the movement of the piston 281 (see FIG. 10 (d)), .

At this time, there is a fear that the piston 281 moves due to the elastic force of the spring and the piston 281 may interfere with the connection between the inside of the cylinder chamber 280 and the second gas moving pipe 250, Thereby forming a piston locking projection 282. The piston 231 moved through the engagement groove of the piston 281 is fixed so that the cylinder chamber 280 and the second gas moving pipe 250 can be continuously connected.

Example 4. Timer means 230 Into the expansion chamber 290 Made portable Throwing expression Life preserver

The operation of the expansion chamber 290 according to the fourth embodiment will be described in detail with reference to FIG. 11 of the accompanying drawings.

Prior to explanation, it should be pointed out that the description overlapping with the first embodiment is omitted in describing the fourth embodiment of the present invention.

Therefore, only the configuration, function, and effect of the fourth embodiment, which is different from the first embodiment, can be described in the following description.

FIG. 11 illustrates an operation process of an expansion chamber according to a fourth embodiment of the present invention.

11 (a), the first gas moving pipe 210 and the expansion chamber 290 are connected to each other. One end of the first gas moving pipe 210 connected to the expansion chamber 290 A pressing member 240 is formed.

At this time, a check valve CV is formed at one end of the first gas moving pipe 210 so that the compressed gas traveling along the first gas moving pipe 210 flows into the expansion chamber 290 through the pushing member 240 A check valve CV is formed at one end of the second gas moving pipe 250 connected to the side of the expansion chamber 290 so that the compressed gas passing through the expansion chamber 290 flows into the second gas moving pipe 250 Respectively.

The expansion chamber 290 and the second gas moving pipe 250 are connected so that the compressed gas introduced into the expansion chamber 290 does not remain in the expansion chamber 290 but can move to the second gas moving pipe 250 And a check valve CV is provided at the position.

The expansion member 291 is formed at a position where the expansion chamber 290 and the first gas moving pipe 210 are connected to receive the compressed gas introduced along the first gas moving pipe 210, (290). At this time, the expansion member 291 is made of a stretchable material and can be expanded by the compressed gas introduced through the first gas moving pipe 210.

At this time, the expanding member may preferably be formed of a membrane (collectively referred to as a coating of a waterproof layer, a paint or the like) film.

The compressed gas is moved along the first gas moving pipe 210 when the safety pin 220 is pulled after the first gas moving pipe 210 is closed by moving the pressing member 240 through the handle 241, The compressed gas is closed by the pushing member 240 and remains in the first gas moving pipe 210 (see FIG. 11 (b)).

The pushing member 240 is moved through the elastic force of the spring connected to the pushing member 240 while the pressure applied to the handle 241 disappears. The compressed gas passes through the pressing member 240 having a width smaller than that of the first gas moving pipe 210 and flows into the expansion member 291 in the expansion chamber 290 through the movement of the pressing member 240.

The compressed gas remaining in the first gas moving pipe 210 is suddenly introduced into the expanding member 291 through the opening of the first gas moving pipe 210 due to the pushing member 240 and the expanding member 291 expands .

On the other hand, in the inside of the expansion chamber 290, a rupture needle 292 is formed on a surface facing the direction in which the expansion member 291 expands and the expansion member 291 is expanded to the position where the rupture needle 292 is located And ruptured by abutting the rupturing needle 292 (see Fig. 11 (c)).

The expansion member 291 expands through the compressed gas introduced into the expansion chamber 290 and at the same time the expansion member 291 ruptures through the rupture needle 292 formed in the expansion chamber 290, And the second gas moving pipe 250 connected to the side of the expansion chamber 290 are connected. The compressed gas introduced into the expansion chamber 290 is moved to the second gas moving pipe 250 connected to the side of the expansion chamber 290 through the expansion and rupture of the expansion member 291 ) Reference).

At this time, since the ruptured expansion member 291 may interfere with the compressed gas moving to the second gas moving pipe 250, the inner surface of the expansion chamber 290 may be designed to have an adhesive force so that the ruptured expansion member 291 may be attached .

The present invention can prevent the tube unit 300, which has been previously inflated by the tube unit 300 from being inflated during reaching the spherical oocyte, from reaching the spherical oocyte, It has a remarkable effect of allowing one life-saving device to reach the survivor's position correctly.

The present invention also has a significant effect of preventing the thrashing of the life-saving device from being disturbed by the inflated tube means 300 by preventing the rapid expansion of the tube means 300 through the timer means 230.

1 to 11 are merely the main points of the present invention, and the present invention is not limited to the configurations shown in Figs. 1 to 11, as various designs can be made within the technical scope of the present invention. It is self-evident.
