[15] Also, there is another effect in that adhesive bands are formed at both end portions of the case, so that they can be simply fixed to the various parts of the body such as arm and leg and so on of the user. [16]

Brief Description of the Drawings [17] The above as well as the other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: [18] FlG. 1 is a developed perspective view illustrating a float-up bag having a gas cylinder contained in a case of a lifesaving device floating on the water according to the present invention; [19] FlG. 2 is a perspective view illustrating a percussion tool for inserting the gas cylinder therein according to the present invention; [20] FlG. 3 is a perspective view illustrating the case of the lifesaving device floating on the water according to the present invention; and [21] FlG. 4 illustrates a combination state and an operation state of the lifesaving device floating on the water containing the folded float-up bag having the gas cylinder. [22]

Best Mode for Carrying Out the Invention

[23] A preferred embodiment of the invention will be described in detail below with reference to the accompanying drawings.

[24] FlG. 1 is a developed perspective view illustrating a float-up bag having a gas cylinder contained in a case of a lifesaving device floating on the water according to the present invention and FlG. 2 is a perspective view illustrating a percussion tool for inserting the gas cylinder therein according to the present invention.

[25] Here, as shown in FlG. 1, the gas is not injected into the float-up bag 10, before the float-up bag 10 is completely contained in a case 40 (note FlG. 3). The float-up bag 10 includes a body 12 divided by a plurality of partition walls open to each other and a gas cylinder receiving portion 11 for receiving the gas cylinders 20.

[26] The material of the float-up bag 10 may be a well-known synthetic resin sheet or a transparent vinyl and so on, such as a PVC, a polyurethane or its equivalents. Also, it may be a waterproof fabric of a well-known nylon oxford material. However, any float-up bag of a waterproof material can be permissible and the present invention is not limited to any material of the float-up bag 10. Here, it can prevent an adhesion phenomenon by means of a well-known embossing process. Preferably, the float-up bag 10 is disposable. However, it may be recycled.

[27] Also, the reason why the partition walls 13 are arranged is that it can prevent a blowout thereof and uphold its shape when the gas cylinder 20 explodes and the float- up bag 10 is expanded later on.

[28] Moreover, the circumference (sealed line 14) of the gas cylinder 20 and the percussion tool 30 of the gas cylinder receiving portion 11 is sealed by means of a general heat fusion and then, is covered with at least double vinyl 15 and 16 by means of a high-frequency welding, so that the gas cylinder and so on is not frozen by keeping warm in a ultra low-temperature state (about -78°C) and it can prevent the damage of the float-up bag 10 during the percussion of the gas cylinder 20.

[29] In the drawings, two gas cylinders 20 are formed in the percussion tool 30 of the gas cylinder receiving portion 11. However, the number of the gas cylinder 20 may be a single or more than three and the present invention is limited to any number of the gas cylinder 20.

[30] As shown in FlG. 2, the percussion tool 30, in which the gas cylinders 20 are inserted, includes a plurality of inserting holes 31 for inserting outlets 21 of the gas cylinders 20, a plurality of arrowheads 32 corresponding to the outlets 21 of gas cylinders 20 in each inserting hole 31, and a gas outlet 33 formed at the front side thereof. [31] A carbon dioxide having a pressure of about 10kg/mm is filled in the gas cylinder

20 about 5-6 liters. However, the present invention is not limited to the kind, pressure and filling amount of the gas and they can be changed according to the circumstances.

[32] Also, as described in herein below, when the gas cylinder 20 explodes, the front side of the gas outlet 33, which is the gas discharge path, is not sealed by the heat fusion or the high-frequency welding, so that the discharge gas is rapidly expanded in the inside of the float-up bag 10.

[33] FlG. 3 is a perspective view illustrating the case of the lifesaving device floating on the water according to the present invention and FlG. 4 illustrates a combination state and an operation state of the lifesaving device floating on the water containing the folded float-up bag having the gas cylinder.

[34] As shown in FlG. 3 and FlG. 4, the case 40 according to the present invention includes a cover 41 connected by a hinge portion thereto and covering the upper portion thereof, a receiving space 42 for receiving the float-up bag 10 and the gas cylinder 20, and a percussion tool operation lever 45 of a plate shape integrally formed at the end portion of the cover 41 and pushing the rear of the gas cylinder 20 during the opening of the cover 41, thereby the outlets 21 of the gas cylinders 20 and the arrowheads 32 of the percussion tool 30 are contacted with each other to be exploded.

[35] Here, the percussion tool operation lever 45 of a plate shape faces the lower direction during the closing of the cover 41. In the meantime, when the cover 41 is completely opened, the percussion tool operation lever 45 pushes the rear of the gas cylinder 20 and the outlets 21 of the gas cylinders 20 move toward the arrowheads 32 of the percussion tool 30 respectively. After all, the arrowheads 32 of the percussion tool 30 are contacted with the sealed outlets 21 respectively to be exploded, so that the gas can be expanded in the inside of the float-up bag 10.

[36] Also, guide protrusions (not shown) are formed at predetermined regions of the both sides of the case 40 and slightly protruded toward the inside thereof, so that it can prevent the gas cylinder 20 from lifting on account of the impact during the explosion of the gas cylinder 20.

[37] The reference numerals 43 and 44 denote a fixing protrusion and a fixing groove for fixing the cover 41 to the case 40 respectively. Also, the reference numerals 47 and 48 denote adhesive bands having both end portions, which are made of a Velcro. The adhesive bands 47 and 48 can be fixed to the arm and leg of a user for the sake of convenience.

[38] The operating method of the lifesaving device floating on the water having the above structure will be described in detail below with reference to FlG. 1 through FlG. 4.

[39] Firstly, the percussion tool 30 having the plurality of gas cylinders 20 therein is putted in the gas cylinder receiving portion 11 formed at one side of the unfolded float- up bag 10.

[40] Continuously, the circumference (sealed line 14) of the gas cylinder 20 and the percussion tool 30 of the gas cylinder receiving portion 11 is sealed by means of the heat fusion and, then covered with at least double vinyl 15 and 16 by means of the high-frequency welding.

[41] Subsequently, the float-up bag 10 having the gas cylinder 20 is folded up and pu tted in the inside of the case 40. Here, the gas cylinder receiving portion 11 having the gas cylinder 20 and percussion tool 30 of the float-up bag 10 is located at the lowest portion of the case 40. That is, the lowest portion of the case 40 assumes the form corresponding the shape of the gas cylinder 20 and percussion tool 30 in order that the gas cylinders 20 and percussion tool 30 are safely placed thereon.

[42] Successively, the remaining portion of the float-up bag 10 is fold over and over again and putted in the upper portion thereof, which is located over the lowest portion of the case 40. Thereafter, the cover 41 is fixed to the case 40 by means of the fixing protrusion 43 and the fixing groove 44, so that the float-up bag 10 having the gas cylinders 20 is completely sealed and putted in the case 40 to complete the lifesaving device floating on the water according to the present invention. Here, the adhesive bands 47 and 48, which are made of the Velcro, are attached on both end portions of the case 40.

[43] Actually, the lifesaving device floating on the water according to the present invention is fixed to the arm and leg of the user through the adhesive bands 47 and 48. In a case that the user is in distress on the water, if the user completely opens the cover 41 of the case 40, the percussion tool operation lever 45 pushes the rear of the gas cylinder 20 and the arrowheads 32 of the percussion tool 30 are perforated into the sealed outlets 21 of the gas cylinders 20, so that the high-pressure gas is spouted and expanded in the inside of the float-up bag 10 to provide the buoyancy with the user.

[44] While this invention has been described in connection with what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments and the drawings, but, on the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims.
