Description

Practice grenade {HAND GRENADE FOR PRACTICE}

The present invention relates to a practice grenade capable of increasing the amount of smoke of the smoke agent.

In general, a grenade is a small bomb for close combat for killing an enemy or destroying a weapon during close combat with the enemy, and is manufactured relatively lightly so that the user can hold it and throw it.

And the types of grenades are classified according to the purpose of use, such as fragmentation grenades for killing people, attack grenades for weapon destruction, gas grenades for reducing enemy power, and smoke grenades for signaling. It is necessary to practice sufficient use or learn safety rules in advance because it can cause damage to oneself and allies due to negligence of the user.

Therefore, during training or practice, not in actual combat situations, practice is performed with a practice grenade manufactured separately so that the explosive power is relatively small and there is no danger to the human body. A detonator tube is installed at the bottom to store explosives.

During practice using such a conventional practice grenade, only the explosion effect due to the ignition of the explosive gunpowder appears, so that the trainees need a visual effect for a more realistic effect.

During military training using these conventional practice grenades, trainees can display an auditory effect due to explosion and visual effects due to smoke emission at the same time, creating an atmosphere similar to the actual combat situation, thereby maximizing training efficiency A hand grenade has been suggested that could do this.

The conventional training grenade includes a bullet body, an adapter assembly and a fuse assembly mounted on the bullet body, and the fuse assembly includes a paper tube cartridge, and the internal space of the branch tube cartridge is filled with upper and lower compartments. Explosives and smokers are deployed.

In such a conventional training grenade, when a spring disposed in the adapter assembly fires a ball to hit the detonator, the detonator is delayed for a certain time by a retardant, and then the detonator disposed in the inner space of the branch tube cartridge detonates and explodes. Together with the combustion of the smoke agent, the smoke film is configured to be discharged to the outside of the body.

However, since the branch cartridge of the conventional practice grenade is made of paper material, the explosive agent does not explode easily during binge drinking and does not burn, so it remains in the branch cartridge and prevents the smoke release of the smoke agent disposed in the internal space of the branch cartridge Due to this, there was a problem of inhibiting the discharge of the smoke screen to the outside of the body.

It is an enlarged side cross-sectional view showing the fuse assembly 30.

1 to 4, the practice grenade 10 may include a bullet body 20, a fuse assembly 30, and a branch tube cartridge 40. For example, a branch pipe 21 made of paper material may be configured to be decomposed in a natural state on the outside of the body 20. For example, the paper through pipe 21 may include kraft paper, which is a paper material. In this embodiment, the paper through 21 is described by way of example of kraft paper, but is not limited thereto. For example, the paper pipe 41 can be variously applied as long as it is a paper material that can be decomposed in a natural state.

The filler (A1) may be filled in the body 20. For example, the filler (A1) may include at least one of ocher or barite. If the filler (A1) is an eco-friendly material, other materials may be applied in addition to the loess or the barite mentioned above. In this embodiment, the filler (A1) will be described by applying ocher. For example, the filler (A1) may include a V-shaped filler (A1).

For example, the filler (A1) containing ocher fills the inside of the body 20 and at the same time has a sense of weight through the ocher, and even if it explodes after throwing, it can prevent damage due to fragments that are fatal to the user. can The filler (A1) not only doubles the explosive effect through red clay dust scattered when the training grenade 10 is thrown on land or sea and explodes, but also naturally disappears and can be decomposed in a natural state.

A closing pad 80 may be disposed to close the opening 20a formed on the front surface of the body 20 . For example, the closing pad 80 may close the opening 20a after filling the inside of the body 20 with the filler A1 through the opening 20a.

The fuse assembly 30 may be coupled to the body 20. For example, the fuse assembly 30 may be penetrated through the closing pad 80 and disposed inside the body 20 .

The branch tube cartridge 40 may be coupled to the fuse assembly 30, and a blasting agent 42 and a smoke suppressant 45 may be disposed. The paper tube cartridge 40 may be made of paper.

The paper tube cartridge 40 may include a paper tube 41, a blaster 42, a fuse 43, and a smoke film filling member 44. For example, a space may be formed inside the branch pipe 41 to dispose the blasting agent 42 and the fuse 43 . For example, a blocking film 60 dividing the interior of the space into first and second spaces 41a and 41b may be disposed.

The first space 41a may be formed above the blocking film 60 to fill the detonation agent 42, and the second space 41b is a second fuse line (of a fuse 43 to be described later). 43b) may be formed under the blocking film 60 to be disposed.

The fuse 43 may be disposed in an inner space of the branch pipe 41 . For example, the fuse 43 may be inserted into the explosive drug 42 and ignited when the explosive drug 42 is drunk. The fuse line 43 may include first and second fuse lines 43a and 43b.

For example, the first fuse line 43a may pass through the blocking film 60 . At this time, one side 43a-1 of the first fuse 43a may be inserted into the explosive 42, and the other side 43a-2 of the first fuse 43a may be inserted into the second fuse ( 43b). In this state, the first fuse 43a may ignite the second fuse 43b when the detonation agent 42 is drunk. At this time, the second fuse 43b can burn a smoke agent 45 to be described later when ignited.

According to various embodiments, the first fuse 43a may be formed in a bar-type shape to penetrate the blocking film 60, and the second fuse 43b may be coupled with the first fuse 43a. In this embodiment, the first fuse 43a may have a shape other than a bar shape, and the second fuse 43b may also have a shape other than the “U” shape. can be applied

According to various embodiments, the second space 41b faces one surface of the blocking film 60, and prevents movement of the blocking film 60 due to heavy drinking when the heavy drinking agent 42 is heavy drinking. A member 70 may be disposed. For example, the movement preventing member 70 may be disposed facing the inner surface of the branch pipe 41 while being disposed in the second space 41b. In this state, the rear surface of the blocking film 60 faces the upper surface of the movement preventing member 70 and can be hooked and fixed at the same time.

The smoke screen filling member 44 may be coupled to an outer surface of the branch pipe 41 . For example, the smoke filling member 44 may fill the smoke agent 45 that is burned when the second fuse 43b of the fuse 43 is ignited.

The smoke film filling member 44 may be made of a soft material that melts and disappears when the smoke smoke agent 45 is burned, and the smoke film filling member 44 can increase the filling amount of the smoke smoke agent 45. It may be made of a ductile material that expands in volume so as to be.

The ductile material may include a ductile synthetic resin material so as to increase in volume. For example, the flexible material may be made of a vinyl material.

For example, the smoke film filling member 44 may be formed in a bag shape with one side open so as to be coupled to the outer surface of the branch pipe 41. For example, the open portion of the bag shape may be coupled with an O-ring 50 to maintain a state in which the smoke film filling member 44 is coupled to the outer surface of the branch pipe 41. For example, the open part of the bag shape is coupled to the outer surface of the branch pipe 41, and in this state, the O-ring 50 is coupled to the open part of the bag shape coupled to the outer surface of the branch pipe 41. can Accordingly, the open portion of the bag shape can be maintained coupled to the outer surface of the branch pipe 41 by the O-ring 50 .

For example, in this embodiment, other coupling members besides the O-ring 50 may also be applied. For example, the other coupling member may include silicon or an adhesive member.

For example, the training grenade 10 may include a bullet body 20, a finishing pad 80, a fuse assembly 30, and a branch tube cartridge 40. For example, the fuse assembly 30 may be coupled to the closing pad 80, and the paper tube cartridge 40 may be coupled to the fuse assembly 30.

An adapter assembly 90 may be coupled to the top of the fuse assembly 30. For example, the adapter conjugate 90 may have at least a part similar to or identical to the adapter conjugate described above. Therefore, since the configuration of the adapter assembly can be easily understood through the above-described embodiments, a detailed description thereof will be omitted.

The fuse assembly 30 is disposed on the lower surface of the fuse 31 screwed to the adapter 91, the detonator 32 disposed at the top of the fuse 31, and the detonator 32, and the fuse ( 31) and an ignition agent 34 disposed on the lower surface of the retardant 33.

In this state, the branch tube cartridge 40 including the aforementioned branch tube 41, blaster 42, fuse 43, and smoke filling member 44 is coupled to the lower portion of the fuse assembly 30 and disposed. can

In this state, the closing pad 80 may be coupled to the opening 20a formed in the body 20 and the opening 20a may be closed at the same time. At this time, the filler (A1) filled in the body 20 and the smoke film filling member 44 coupled to the paper tube cartridge 40 may come into contact. For example, since the smoke film filling member 44 is made of a soft material, the smoke film filling member 44 made of a soft material will be deformed to fit the shape of the filler A1 while in contact with the filler A1. can For example, the filling body may be formed in a V-shaped filling body. The smoke film filling member 44 may be deformed and corresponded to at the same time as it comes into contact with the V-shaped filling body.

In this state, when the practice grenade 10 is thrown onto land or sea, the user holds the bullet body 20 and the safety handle 95 with one hand while holding the safety pin 94 and the safety clip with the other hand. After removal, the practice grenade (10) can be thrown.

In addition, since the thrown training grenade 10 loses the force applied to the safety handle 95, the ball 92 strikes the detonator 92 in the fuse assembly 30 by the elastic force of the spring 93 will do

Next, the detonator 92 may be detonated and ignited by the impact force applied from the ball, and then the retardant 33 may be ignited. At this time, the retardant 33 allows the explosion of the detonator 62 to be delivered after a certain period of time instead of immediately to the blaster 42 disposed in the branch tube cartridge 40, so that the practice grenade 10 is It can be thrown or exploded from a distance.

In addition, when the explosive agent 42 is ignited, it can explode through the explosive hole 41c formed on the side of the branch tube cartridge 40 .

At the same time, the explosive sound of the blasting agent 42 ignites the first fuse 43a of the branch tube cartridge 40, and the ignited first fuse 43a ignites the second fuse 43b of the branch tube cartridge 40. ) can be ignited.

The second fuse 43b may burn the smoke agent 45 of the smoke film filling member 44 disposed outside the branch tube cartridge 40 when ignited.

At this time, the smoke film filling member 44 may melt and disappear when the smoke smoke agent 45 is burned. At the same time, the smoke agent 45 may explode together with the filler A1 of the bullet body 20 .

At this time, at least two release holes 81 may be formed in the finishing pad 80 to release the explosive sound and the smoke film generated from the explosive agent 42 and the smoke suppressant 45 . For example, the at least one discharge hole 81 is capable of discharging the explosive sound of the explosion agent 42 and the smoke film of the smoke agent 45 generated inside the body 20 to the front of the body 20. can Accordingly, the at least two or more discharge holes 81 can further enhance the explosion effect of the explosive agent 42 and the smoke effect of the smoke suppressant 45 .

Therefore, the practice grenade 10 can create an atmosphere similar to an actual combat situation by displaying a visual effect as if the grenade 10 actually exploded.

At this time, in the practice grenade 10, the bullet body 20 is exploded by the detonation of the explosive agent 42, and the filler A1 filled in the bullet body 20 is scattered and falls into the land of the land or the water of the sea. In addition, the filler (A1) can further maximize the smoke effect of the smoke agent 45. For example, since the filler (A1) includes ocher, the smoke-casting agent 45 may develop a yellow smoke film that can be visually recognized by the ocher.

In addition, in a state where the user's hand (not shown) holds the side of the body 20, when the body 20 explodes, the explosive sound of the explosive agent 42 and the smoke film of the smoke agent 45 are at least It is possible to prevent damage that may occur in the user's hand by being released to the front of the bullet body 20 through two or more discharge holes 51.

For example, the environment-friendly filler (A1) filled in the body 20 and at least two discharge holes 81 formed in the finishing pad 80 of the body 20 are a high-low pressure part system in the body 20. The structure can be manufactured, and the eco-friendly filler (A1) and at least two or more discharge holes 81 manufactured in this way are damaged when the body 20 explodes (eg, in case of circular destruction and explosion between grips) of the body 20 Not only this does not occur, but also the occurrence of damage to the human body can be prevented.

As such, the paper tube cartridge 40 is made of a material that easily melts the smoke agent 45 when burned, and has a volume so that a large amount of smoke agent 45 can be filled in order to increase the smoke amount of the smoke agent 45. By configuring the smoke film filling member 44 made of an elongated soft material, the smoke film filling member 44 can improve the smoke generation of the smoke agent 45 in the paper tube cartridge 40, and the smoke agent 45 The amount of smoke can also be increased, and thereby the smoke effect of the smoke agent 45 can be further improved.

In addition, since the smoke film filling member 44 is a material that easily melts and disappears when the smoke film 45 burns, environmental pollution that may remain on land or in the sea can be prevented.

The practice grenades of various embodiments of the present invention described above are not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes are possible within the technical scope of the present invention.
