Description

Description: TECHNICAL FIELD The present invention relates to a signal projectile launching device. More specifically, the present invention relates to a small, lightweight, and easy-to-operate signal bullet launching device.

[Conventional technology and its problems] Conventionally, there is a signal device described in JP-A-59-189297.

The signal device is configured such that the grip portion includes a trigger means and a rotating means of a magazine, and when the grip portion is held in a natural state by hand, the long axis of the magazine is oriented substantially in a vertical direction. It is detachably attached to the grip portion, and its firing direction is configured to be vertically upward in parallel with the long axis of the magazine. "

However, the signal device has various problems as follows.

Since the signal device has a configuration in which a separate magazine is attached to a grip member, the signal device is large as a whole and too large to operate with one hand. Therefore, operation with one hand is difficult.

In the signal device, since the grip portion and the magazine are detachable, there is a risk that the magazine is detached from the grip portion during the firing operation. This signal device, for example, when a person thrown into the sea at the time of the sea accident, when accidentally remove the magazine from the grip, if the magazine or grip was dropped into the sea while being caught in the waves The signal device having such a configuration is completely powerless and meaningless.

Since the signal device has a configuration in which a plurality of signal bullets are mounted on a magazine, it is complicated to mount a plurality of signal bullets on a magazine.

The signal device is configured so that the arm is extended horizontally and the grip portion is gripped, and the grip portion is strongly pressed to activate the triggering means to vertically emit a signal bullet. Then, when the signal bullet is fired, the arm extended horizontally receives a downward force due to a reaction at the time of firing the signal bullet, and turns obliquely downward. As a result, when the signal bullet is fired vertically, the arm is pushed down obliquely downward, and the fired signal bullet is fired obliquely upward or in an unexpected direction.
In order to fire a signal bullet vertically upward as desired, the arm holding the grip must be supported and fixed with the other hand. Ultimately, both hands are required to operate the signaling device. In situations where signal bombs must be fired, the operator may be injured, or in the event of a marine accident, may be forced into an unstable position in the waves. It is a story that is impossible at all.

[Object of the Invention] The present invention has been made based on the above circumstances.

An object of the present invention is to provide a small and lightweight signal bullet launcher that can be operated with one hand.

Another object of the present invention is to provide a signal bullet firing device that can be reliably operated.

Still another object of the present invention is to be able to reliably fire a signal bullet with one hand in the vertical direction, and to prevent the next signal bullet from being fired even if one signal bullet is missed. The object of the present invention is to provide a signal projectile launching apparatus which does not have any problem.

[Means for Achieving the Object] According to a configuration of the present invention for achieving the object, an apparatus main body of a grippable size provided with a firing pin operating means operable by a grasping force, and a distal end surface of a signal bullet Consists of a magazine in which a plurality of signal bullets are mounted in a row so as to protrude from one end surface of the magazine housing, and a signal bullet launching hole opened in a direction perpendicular to the long axis of the mounting body in the mounting body. A magazine mounting portion provided with a magazine discharge hole for discharging a magazine at the same time as loading a magazine, and a signal bullet facing the signal firing hole is fired by the firing pin operating means, and then the next signal bullet is fired. A biasing member for pushing a magazine from the magazine discharge hole so as to face the signal bullet discharge hole is provided, and a sliding member along the signal bullet discharge hole and one end of the slide member are provided in the apparatus main body. Slide so as to cover a part of the hole and form a magazine housing discharge hole. A sliding member biasing member for biasing the moving member, and a magazine engaging portion that abuts on one end of the sliding member and abuts on the distal end surface of the signal bullet projecting from the magazine housing to lock the magazine. It is a signal bullet launching device characterized by being provided.

[Operation] This signal bullet launching device has a signal bullet launching hole that opens in a direction perpendicular to its long axis of a device main body that can be gripped. When the arm holding the main body of the apparatus is set upright, the signal bullet shooting hole is open upward.

When the firing pin is actuated with a grasping force, the signal bullet is fired vertically and the reaction of the fired signal bullet is applied to the extended arms and shoulders. When firing a signal bullet from a conventional signal device held in a horizontally extended hand, the arm was pushed down by the reaction of the signal bullet firing, and it was not possible to fire the signal bullet accurately in the vertical direction, In this signal bullet launcher, since the arm is not pressed down as in the related art, the signal bullet is accurately launched in the vertical direction.

In this signal ammunition launching device, a signal magazine in which a plurality of signal ammunition are mounted in a row so that the distal end surface of the signal ammunition protrudes from one end surface of the magazine housing is used. It is attached to the magazine attachment part so as to face. The magazine is urged by an urging member in a direction of being discharged from the magazine discharge hole. The magazine discharge hole is set to a size such that a magazine formed by mounting a signal bullet is discharged such that a distal end surface of the signal bullet projects from one end surface of the magazine housing.

A part of the magazine discharge hole is covered by a sliding member urged by the sliding member urging member, and forms a magazine housing discharge hole smaller than the magazine discharge hole. The magazine housing discharge hole is set to a size such that only the magazine housing is discharged. On the inner peripheral surface of the sliding member, there is provided a magazine engaging portion for engaging the leading end surface of the signal bullet projecting from one end surface of the magazine housing and engaging the magazine. Therefore, when the distal end surface of the signal bullet loaded in the signal bullet faces the signal bullet launch hole, the distal projecting portion of the signal bullet that abuts the magazine locking portion becomes an obstacle, and the magazine housing is discharged from the magazine housing. The hole cannot be completely removed.

Therefore, if a signal bullet facing the signal bullet launch hole is fired by the firing pin operating means, the signal bullet which had been an obstacle for the magazine housing to escape from the magazine housing discharge hole until then disappears. A part of the energized magazine case is discharged from the magazine case discharge hole such that the leading end surface of the next signal bullet faces the signal bullet discharge hole. Here, in the event that the signal bullet facing the signal bullet launch hole is not exploded, the sliding member forming the magazine housing discharge hole by covering a part of the magazine discharge hole with one hand. If the sliding member is slid in the direction opposite to the biasing direction of the sliding member biasing member, that is, in the direction in which the signal bullet is fired, the magazine has been obstructed until then from the magazine discharge hole. The magazine lock moves in the direction in which the signal ammunition is fired, and the magazine ejection hole appears.Part of the magazine is ejected from the magazine ejection hole so that the tip surface of the next signal ammunition faces the signal ammunition ejection hole. Is done.

If this operation is repeated one after another and all of the signal bullets loaded in the magazine housing are fired, the obstacle that the magazine housing is discharged from the magazine housing discharge hole disappears, so this magazine housing is used as a biasing member. It is pushed and easily discharged from the magazine housing discharge hole.

[Effects of the Invention] According to the present invention, having the above-described configuration, (1) a small-sized signal bullet emitting device that can be gripped with one hand can be obtained, and (2) a signal bullet emitting hole is formed in the device body. Opening in the direction perpendicular to the long axis of the arm, even if you raise the arm high and operate the firing pin operating means to fire a signal bullet in the vertical direction, the reaction at the time of firing the signal bullet only affects the arm and shoulder Since there is no reaction in the direction in which the arm is tilted, the signal bullet is always launched vertically as long as the signal bullet is fired with the arm directed vertically. Therefore, unlike a conventional device that attempts to hit a signal bullet vertically from a signal device held in a horizontally extended hand, it does not say that the hitting direction is deviated. (3) After the signal bullet is fired The magazine housing is pushed by the urging member and moves automatically to the position where the front end surface of the next signal bullet faces the signal bullet launch hole. In addition to realizing the firing of signal bullets, even if a signal bullet is not fired,
Only by operating the sliding member, a part of the magazine is discharged from the magazine discharge hole, so that the next signal bullet can be easily prepared for firing. (4) Since the movement of the magazine is performed by the biasing member,
It is possible to provide a signal bullet launching device having various advantages such as a very simple configuration, and therefore, a device with few failures.

Therefore, as long as the first safety pin is not removed, even if the firing pin operating means 29 is operated, the firing pin 30 does not strike the detonator 16, so that the malfunction of the signal bullet emitting device 1 is prevented.

In addition, since the second safety pin penetrates through the operation member 39 and the apparatus main body 8, the movement of the intermediate piece 44 is restricted to be inoperable. Therefore, as long as the second safety pin is not pulled out, even if the first safety pin is pulled out, even if the primer charging hole 14 faces the firing pin through hole 20, the rotation of the firing pin support piece 31 for supporting the firing pin 30 is performed. Since the dynamic operation is prevented, no malfunction of the signal bullet emitting device 1 is caused. Thus, the signal bullet launcher 1 is prevented from malfunctioning when not in use by the first safety pin and the second safety pin. Therefore, the signal bullet launching device 1 is extremely safe.

When using the signal bullet launcher 1, the first safety pin and the second safety pin are pulled out.

When the contact piece 35 is pushed, as shown in FIG. 5, it rotates in the direction opposite to the direction of arrow A in the firing pin support piece 31.

When the pressing piece 43 continues to press the contact piece 35, the pressing piece 43
Moves on the contact surface of the contact piece 35, and the tip of the pressing piece 43 finally comes off the contact piece 35. As a result, the second
By the urging force of the urging member 37, the firing pin support piece 31 is rapidly rotated in the direction of arrow A in FIG. Then, the firing pin 30 penetrating the firing pin through hole 20 hits the primer 16.

The propellant in the signal bullet 12 is ignited by the impact of the primer 16, and the signal bullet 12 is fired from the signal bullet launch hole 17 toward the sky.

When the first signal bullet 12 is fired, the signal bullet 12 locked by the magazine locking portion 26 provided on the sliding member 24 is lost, so that the first urging member 21 By the urging force, the magazine 10 is moved so that the portion of the magazine housing 11 in which the first signal bullet 12 is loaded projects from the storage housing discharge hole 27. The magazine 10 is moved by the urging force of the first urging member 21 until the tip of the second signal bullet 12 comes into contact with the magazine locking portion 26.

In the event that the first signal bullet 12 is not fired, the sliding member operation piece 27 housed in the sliding member 24 is raised to stand up, and this sliding member operation is performed. By pressing the piece 27 with one hand and sliding the sliding member 24 in the traveling direction of the signal bullet 12,
The magazine 10 by the contact between the magazine locking part 25 and the tip of the signal bullet 12
At the same time as the lock is released, the magazine discharge hole 23, a part of which has been covered by the sliding member 24, completely appears, so that the magazine 10 whose position movement has been prevented until then, Due to the urging force of the first urging member 21, the portion where the first signal bullet 12 which was unexploded is mounted is the magazine discharge hole.
Move to project from 23.

At this stage, the distal end face of the second signal bullet 12 faces the signal bullet launch hole 17 and the primer loading hole 14 faces the firing pin through hole 20. Also, the pressing of the operation member 39 is stopped,
When the force of the finger is released, the operating member 39 rotates in the direction of arrow B as shown in FIG. 2 by the urging force of the third urging member 39, and the rotation of the operation member 39 causes the intermediate piece 44 to rotate. By being pulled, the tip of the pressing piece 43 fits into the notch of the guide piece 36. The tip of the pressing piece 43 faces the contact piece 35.

Thus, the second signal bullet 12 is ready to be fired.

The firing of the second signal bullet 12 is the same as that of the first signal bullet 12
Is the same as the firing operation of

As described in detail above, the device of this embodiment has a magazine mounted in the device main body, and therefore can be a small signal bullet launching device. In addition, by simply operating the operating member, it is possible to fire signal bullets one after another, and even in the event that one signal bullet fails to fire, the slide member is operated to prepare for launching the next signal bullet. Is completed. Therefore, the operation of launching a signal bullet is very simple and reliable.
