Description

Throwing ball for throwing

The present invention relates to an inflatable life preserver for throwing, and more particularly, to an inflatable life-saving ball for inflation is initiated by throwing directly to the water distress, or directly exposed to the water in the state of carrying the victim.

In recent years, the population of marine sports and water play is increasing regardless of season. However, in the case of these marine sports or playing in the water, accidents may occur due to accidents. Most accidents occur due to immaturity of swimming, but in some cases, the tube for water play may be damaged or overturned by a play boat.

In order to prevent such accidents, various kinds of life-saving tools are provided in the water play places to help the lives of the victims. As an example of a life tool, a tube etc. can be mentioned.

However, there is a problem that the tube as a lifesaving tool cannot be thrown accurately to the position of the rescue requester who needs to be rescued. That is, the volume of the tube itself is large, which makes it difficult for the user to hold it correctly. In addition, since the tube itself is light in the air-filled configuration of the plastic paper, it was not easy to accurately throw away and to the location of the rescue requester due to the easy wind blowing during throwing. Therefore, even when an emergency such as a human accident occurred, throwing the tube a plurality of times in order to save the person drowned.

In addition, the conventional life-saving tube was inconvenient to carry due to the large volume as described above, which causes a weak problem that the life-saving scope of the life-saving tube is bound to be limited.

In addition, the conventional life-saving tube did not properly respond when the air is filled inside when left for a long time when rescue is necessary. In order to prevent this, there is a need to check the tube condition from time to time, which causes an increase in operating costs.

In order to solve the disadvantage of the conventional life-saving tube, there is an example of using a tube that is automatically expanded through a chemical reaction as a lifesaving tube. This has the advantage of improving the lifesaving ability than conventional tubes due to the advantage of throwing the tube to a long distance.

The principle of the tube which is automatically expanded through such a chemical reaction is as follows. That is, a predetermined amount of gas-generating raw material powder is filled in the tube body, and the tube body is expanded by generating gas according to the chemical reaction of the liquid medicine. Alternatively, a mixture of certain solids in the tube causes a chemical reaction to produce a gas and expand the tube compressed by the gas.

However, since the tube is automatically expanded through a chemical reaction, the chemical reaction may not occur. This is a chemical reaction does not occur depending on a number of factors, such as problems in the manufacturing process or storage problems. Alternatively, the tube may be inflated at a time when the expansion is not necessary due to the medicine filled in the tube.

Conventional technology that performs the function to solve the above problems, as shown in Republic of Korea Patent Registration 10-1064610, the folded state during the throwing and the tube portion to expand after throwing, the form is easy to throw in the folded state of the tube portion A housing which accommodates the tube portion to be maintained at the tube portion and is damaged when the tube portion is inflated, an expansion device portion provided in the tube portion to expand compressed carbon dioxide according to an external control signal, and expand the tube portion, and the tube portion to a desired position. In the throwing life-saving tube comprising a remote controller for sending a control signal to the inflation device by the user's operation when throwing in, The inflation device comprises: a receiving unit for receiving a control signal of the remote controller; A control unit for supplying and controlling power when a control signal is received in the receiving unit; And a cocking chamber is provided at one side, and a first guide portion and a second guide portion having a smaller diameter than the cocking chamber are continuously provided at the other side, and a plurality of heat dissipation fins are provided on the outer surfaces of the first guide portion and the second guide portion. And a body part having a plurality of pressure releasing holes provided in the first guide part adjacent to the compartment, an upper cap configured to seal the compartment and lead an electric wire into the compartment, thereby triggering the trigger. The ball is formed by the air that is expanded by the air is expanded when triggered to form a perforation in the cartridge coupled to the end of the second guide portion, the ball and ball to be restored to its original position by the elastic portion, the first guide portion and the second Located in the outer space of the guide portion, providing a compartment between the outer surface of the first guide portion and the second guide portion, the heat expansion is discharged through the pressure relief openings A side case part for exchanging heat between the supplied air and the gas discharged from the cartridge, and a side penetrating part inserted into a side of the body part provided with the side case part and the second guide part to supply gas discharged from the cartridge to the tube part. It is composed of a discharge portion is triggered by the supplied power, and is configured to form a perforation in the cartridge in which compressed carbon dioxide is stored.

However, the prior art configuration has a problem that the inconvenience to operate through the remote control and when the chemical reaction does not occur or expands at any time, it does not faithfully perform the function as a lifesaving tube.

Looking in more detail with respect to the throwing expansion life ball 100 according to the present invention.

This, throwing expansion life ball 100 is composed of a tube portion 110, a case portion 120, the pressing portion 130, the expansion means 140.

At this time, the tube part 110 is accommodated in a folded state inside the case part 120 and expands during throwing. In addition, the tube portion 110 is wrapped around the body portion 150 and the pressing portion 130, the installation is finished in the lower portion 150. Here, the tube portion 110 is preferably a material having a waterproof function and elasticity is not limited thereto.

In addition, the case part 120 includes a pair of the first cover 121 and the second cover 123 that accommodate the tube part 110. The case part 120 covers the second cover 123 and the upper part of the second cover 123 with the first cover 121.

In addition, the case portion 120 is preferably a spherical shape to facilitate throwing, but is not limited thereto. That is, as long as it can accommodate the tube part 110, a pair of polygonal shapes are possible.

At this time, the first cover 121 and the second cover 123 are coupled in an interference fit method or a light adhesive method.

Further, the connecting means 125 protrudes from the upper peripheral edge of the first cover 121. When the extension member 127 is connected to the connecting means 125 and hanged on the garment, the life ball 100 may operate when drowned. In addition, people outside the water can easily carry the life ball 100 through the connecting means 125.

In addition, as shown in FIG. 2 and FIG. 3, a connection string 180 is provided on one side of the case part 120. The connection strap 180 prevents the first cover 121 and the second cover 123 from being separated after the first cover 121 is opened. Thus, the first cover 121 can be prevented from being lost through the connecting string 180, and thus the case part 120 can be repeatedly used.

On the other hand, the body portion 150 is installed below the second cover 123. The body portion 150 has a cylindrical shape with an upper portion opened. In this way, the guide hole 153 penetrates inside the housing 151 in which the upper portion is opened.

In addition, the protective member 160 is installed to surround the lower outer periphery of the body portion 150 to prevent the intermittent means 137 from touching the water. Furthermore, a plurality of discharge holes 155 penetrate the upper outer periphery of the housing 151 to supply gas generated through the expansion means 140 to the tube part 110.

In addition, the pressing unit 130 is accommodated inside the case unit 120 and operates when it touches water after throwing to separate the case unit 120. The pressing unit 130 is moved up and down by inserting a cylindrical pressing member 131 into the body portion 150.

Furthermore, a plurality of locking pieces 133 that are divided into lower portions of the pressing member 131 are selectively caught by the guide holes 153 through the water-soluble control means 137. At this time, the interrupting means 137 is in a solid state until it touches the water and melts when it touches the water so that the locking piece 133 is folded to release the locking state of the pressing unit 130.

In particular, the elastic member 135 is installed inside the body 150. The elastic member 135 provides an elastic force to the pressing member 131, and when the interrupting means 137 melts, the pressing member 131 is pushed up to raise the pressing member 131. As such, when the raised pressure member 131 pushes up the inner surface of the first cover 121, the first cover 121 is separated from the second cover 123.

On the other hand, the expansion means 140 is accommodated in the case portion 120 to inflate the tube portion 110 after the operation of the pressing unit 130. The expansion means 140 is preferably a water-soluble organic acid for food additives because it should not adversely affect the human body and the environment when disposed or damaged by a water-soluble organic acid. In general, sodium bicarbonate is hydrochloric acid, sulfuric acid, nitric acid, Although carbonic acid gas is generated by reaction with acids such as oxalic acid (hydroxyl) and the like, it is not preferable because it is harmful to the human body.

As the water-soluble organic acid, lactic acid, ascorbic acid, tannic acid, citric acid, acetic acid, malic acid, fumaric acid, gluconic acid, succinic acid or mixtures thereof may be used, and more preferably citric acid may be used.

Citric acid (citric acid) is an organic acid most obtained from citrus fruits as a metabolite of animals and plants existing in nature, organic acid for food additives used in various ways such as acidifiers, pH regulators, antioxidants, astringents etc. to be.

In addition, the guide rod 170 having the locking member 171 is inserted into the insertion hole 139 penetrated in the center of the pressing member 131 is inserted. At this time, the locking member 171 is larger than the diameter of the insertion hole 139.

Further, the stopper member 173 is screwed to the lower portion of the guide rod 170 and the pressure member 131 is raised to raise the guide rod 170 so that the stopper member 173 seals the lower portion of the body portion 150.

On the other hand, in order to increase the sealing force of the guide hole 153, the pressing member 131, the stopper member 173 may be installed (unsigned).
