Abstract

PURPOSE:To miniaturize the set and improve the environmental afficity thereof by simultaneously turning two pieces of triggers to select the terminal of fuse head of signal bullets and to fire and inject the signal bullets when the set is triggered. CONSTITUTION:The gunloch 8 acts in two stages. The triggers 20 and 21 are pushed up by an arm 18 and are turned around a turning shaft 33 when the gunloch 8 is pulled. The trigger 21 turns cooperatively with the trigger 20 and its front end pushes up the button of a rotary switch 28. The turning of the trigger 21 stops and the rotary switch 28 selects a terminal connecting the leg wire of the spot fire balls of the signal bullets in a magazine to be distributed with electricity, thus forming an ignition circuit when the pushing up attains the extreme limit. The turning of the trigger 20 is continued and a leaf spring 30 of a switch 29 is pushed up when the gunloch 8 is kept pushed further. A button 31 is then pushed to turn the switch on and an ignition current is transmitted to the fuse head of the signal bullet, by which the fuse head is ignited. The firing compd. existing around the spot fire ball is fired by the heat energy generated at that time and the signal bullet is fired and shot by the gas of a high temp. and high pressure generated by the combustion thereof.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifesaving signal continuous shooting set (hereinafter referred to as a set).

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application No. 4-77612 is known as a prior art of a signal bullet continuous firing device. Since this device is mechanically configured, the magazine pops out during continuous firing, and the shape of the entire device changes, so sealing is difficult, and there are drawbacks such as water entering during cold weather and freezing and inoperability.

[0003]

Therefore, even under the severe environmental conditions of being submerged in water below the freezing point in the event of a disaster, it will not freeze and will not stop operating, and it will function safely and reliably, and the flight of the pilot. SUMMARY OF THE INVENTION It is an object of the present invention to realize a lifesaving signal projectile continuous launching device that is small and compact that can be stored in a limited space such as a pocket of clothes, and that can be easily operated with one hand.

[0004]

[Means for Solving the Problems] This purpose is
(A) A magazine arranged in a line (installed in parallel) in which a required number of signal bullets are housed in a hermetically sealed state, and a propellant and an ignition ball which are arranged at the bottom of the magazine and are hermetically sealed. It became free by pulling out the propellant chamber, the magazine part consisting of a connector in which the legs of the ignition ball coming out from the bottom of the propellant chamber were electrically connected to the corresponding terminals, and (b) the safety pin was pulled out. A safety release mechanism that pushes the button of the safety release switch to release the safety by pulling out the safety stopper, and two triggers that are locked by two interlocking springs when the trigger is pulled have the same rotation axis. Rotate simultaneously, one of the triggers is a power distribution mechanism that stops the rotation by selecting the terminal of the ignition ball of the signal bullet that should send the ignition current by pressing the rotary switch, and further pulling the trigger The trigger of the power distribution mechanism remains stopped The other trigger continues to rotate to turn on the ignition switch of the firing / discharge switch, burn the propellant to ignite and eject the signal bullet, and loosen the trigger after the end of firing to fire / discharge switch. The ignition switch is turned off and the discharge switch is turned on to prevent unnecessary discharge of the power source due to a short circuit in the ignition ball, and the charge accumulated in the capacitor of the ignition circuit for the next firing is zeroed. A firing and discharging mechanism that forms a circuit, a base on which the elements that form each of the power distribution, firing and discharging circuits are assembled, a connector that controls the interface with the magazine section, and a grip section that includes a power source, and (c)
In addition, it can be achieved by a set composed of a rubber bag that tightly seals the magazine portion and the grip portion in a state of being connected to each other.

[0005]

[Operation] Pull out the safety pin, pull out the free safety plug to release the safety, and pull the trigger, and the two triggers locked by the two interlocking springs will rotate simultaneously around the same rotation axis. One of the triggers turns the rotary switch to turn on the rotary switch to select the terminal of the ignition ball of the signal bullet to which the ignition current should be sent, and the rotation stops. When the trigger is pulled further, the other trigger continues to rotate while turning on the ignition switch of the ignition and discharge switch, ignites the ignition ball to burn the propellant, and Signal bullets are ignited and ejected by the high-pressure combustion gas.

When the trigger is loosened after the end of the firing, the ignition switch of the ignition / discharge switch is turned off and the discharge switch is turned on to prevent the unnecessary discharge of the power source due to the short circuit of the bridge in the ignition ball. The charge accumulated in the capacitor of the ignition circuit for the firing is reduced to zero. If you squeeze the loosened fingertip and pull the trigger, you can move to the next firing stroke. During this time, the outer shape of the set remains unchanged, and since it is completely sealed with a rubber bag, water does not enter the inside and freeze during cold weather, and the set does not become inoperable.

It is composed of a magazine part 4, a grip part 2 fixed integrally with the magazine part 4, and a rubber bag 5 which closely adheres to the side lower surface of the magazine part 4 to seal the inside of the set 1. However, the rubber bag 5 is shown by a two-dot chain line in FIG. 1 for convenience of drawing. The grip part 2 is designed to have a narrower width toward the lower side and a bulge at the lower end to facilitate gripping, and the index finger and the middle finger hit the tip part of the trigger 8, facilitating continuous firing trigger operation. I tried to become.
The size of the set 1 was 167 mm in length, 62 mm in width, 27 mm in thickness, and 320 gr in weight, and the whole was rounded to have a structure in consideration of storability. Grip part 2 and magazine part 4
Polyacetal copolymer (hereinafter referred to as POM), which is resistant to impact, was used as the material for the body material and most of the body constituent members except the screws, shafts, springs, etc., and was molded by shaving.

The body of the grip portion 2 is shown in FIGS.
As shown in, the upper lid 7 is fixed to the body 6 by six countersunk screws 9. Further, as shown in FIGS. 1 and 2, the body of the grip portion 2 and the magazine portion 4 are fixedly integrated by screwing from both side surfaces with countersunk screws 3. FIG. 5 shows the upper surface of the set 1, but since the upper surface is flatly sealed with resin 75, the signal bullets loaded inside the magazine section 4 are not shown, and the end surface of the cylindrical aluminum liner 65 is not shown. I can see it.

FIG. 6 is an explanatory view showing the internal structure of the set 1. The situation where the upper lid 7 of the grip part 2 is removed and the situation where four magazines 60 on one side of the magazine part 4 are lined up are shown. The magazine 60 has a cylindrical shape, and a liner 65 is fitted therein.
Although a total of eight staggered rows are arranged in a row, FIG. 6 shows only four on one side. The magazine 60 is sealed with a sealing plate 63 and a resin 75 after loading a cylindrical signal bullet (the loading condition is not shown in the drawing flight).

In FIG. 6 showing a state in which the upper lid 7 of the grip portion 2 is removed, and FIG. 9 showing a state in which the base 11 is removed from FIG. 6, the safety stopper 13, the safety stopper arm 14, and the safety releasing member are shown. Switch 15, button 17, and leaf spring 16

The connector that controls the power supply and the power supply battery 10 (nominal 3V, lithium battery) are shown.

The board 11 on which elements such as capacitors and resistors are assembled is assembled to the body 6 of the grip portion 2 by three countersunk screws 31a. The safety release switch 15 is brazed to the front side of the base 11, and the ignition switch 29 is soldered to the back side of the base 11 to form the mechatronics mechanism of the present set 1. Glass fiber epoxy resin FRP is used as the material of the base 11.
It was used.

FIG. 7 is a sectional view taken along the line AA of FIG. 2, FIG. 8 is a sectional view taken along the line BB of FIG. 6, and FIG. 9 shows three countersunk screws 31a for fixing the base plate 11 to the body 6. FIG. 9 to FIG. 11 show the internal structure after the base 11 is removed by pulling out from the base 31b, FIGS. 9 to 11 show the operation mechanism of the set 1, and FIG.

The operation mechanism of the set 1 will be described below with reference to FIGS. 6 to 12.

FIG. 6 shows a state in which the safety plug 13 is inserted in the body 6, and is normally carried in this state. Since the safety plug 13 is fixed by the safety pin 41, in order to operate the set 1, the safety pin 41 must first be pulled out. In an emergency, hold the grip part 2 with your right hand (about 80% of Japanese are right-handed), hold your mouth with your left hand if necessary, and pull out the safety pin 41. Since the safety pin 41 is on the operator's body side, it is easy to pull out. When the safety pin 41 is pulled out, the safety plug 13 becomes free and can be pulled out easily. By pulling out the safety stopper 13, the safety stopper arm 14
Pushes the leaf spring 16 of the safety release switch 15 and pushes the button 17 to release the safety. The switch 15 of this safety release mechanism is shown as SW1 in the circuit diagram of FIG. SW
1 is normally open, that is, in the off state, but is closed or turned on when the safety plug 13 is pulled out, and the preparation for firing is completed. FIG. 9 shows the state, and the safety plug 13 is pulled out.

The safety plug 13 is a POM round bar whose base is sealed by an acrylic rubber O-ring 80.
Since the safety pin 41 is inserted through the lower body of the body 6, the airtightness inside the grip portion 2 is not broken.

Next, the trigger 8, the arm 18 of the trigger 8, the spring 19 for the trigger 8, the rotating shaft 32 of the trigger 8, the trigger 2
0 and 21, interlocking springs 22 and 23 between the trigger 20 and the trigger 21, interlocking springs 22 and 23
Securing knobs 24, 25 and 26 and trigger 2
0 and the power transmission device consisting of the rotary shaft 33 of the trigger 21, the power distribution device of the rotary switch 28 and the button 27 forming a circuit for sequentially distributing the firing current to the signal ball firing ball, and the firing current to the signal ball firing ball. An ignition and discharge device including a switch 29, a leaf spring 30 and a button 31 for transmitting electricity and preventing discharge of the power supply battery 10 after completion of ignition and forming an integration circuit to prepare for the next emission, and the magazine part 4. Connector 1 that controls the interface with
The operation of the electrical connection device 2 and the power supply of the battery 10 will be described.

The trigger 8 acts in two steps. The trigger 8 is pivotally supported by a rotary shaft 32, is prevented from being rotated by the bending stress of a spring 19, and has an arm 18 attached to its tip. As the spring 19, a coil torsion spring having a small number of turns and a relatively large bending stress is used. Since the rotating shaft 32 is located below the grip portion 2, the index finger and the middle finger of the operator's right hand hit the vicinity of the tip of the trigger 8, which facilitates the operation. When the trigger 8 is pulled against the bending stress of the spring 19, the triggers 20 and 21 are pushed up by the arm 18 and rotate about the rotation shaft 33 against the bending stress of the springs 22 and 23. For the springs 22 and 23 of the triggers 20 and 21, coil torsion springs with many turns are used.
It was wound around the rotary shaft 33 and used. The spring 22 has one end connected to the body 6 and the other end connected to the trigger 21 by a knob 26. Also, the spring 23 has one end with the knob 2
4 and the other end to the trigger 20 and the trigger 21, respectively. Therefore, the trigger 21 rotates in conjunction with the trigger 20, and its tip pushes up the button 27 of the rotary switch 28. When the push-up reaches the limit, the rotation of the trigger 21 is stopped, and the rotary switch 28 forms a firing circuit by selecting the terminal connected to the leg of the ignition ball of the signal bullet of the magazine 60 to be distributed. It was designed to reach this state when the trigger 8 was pulled around the rotary shaft 32 by 9 °.

Even if the rotation of the trigger 21 is stopped, if the trigger 8 is further pulled, the rotation of the trigger 20 continues while the tip of the trigger 21 keeps pushing up the button 27 of the rotary switch 28. To be done. This trigger 2
As the rotation of 0 continues, the leaf spring 30 of the switch 29, which is in charge of the firing and discharging mechanism, is pushed up, and the button 31 of the switch 29 is pushed to turn it on. Immediately, the ignition current is transmitted to the ignition ball of the signal bullet for ignition. The ball is ignited, its thermal energy ignites the surrounding propellant, and the high temperature and high pressure gas generated by the combustion ignites and ejects the signal bullet. At this time, the trigger 8 is about 1 around the rotary shaft 32.
It is in the state of being pulled in by 3 °, and the situation is shown in FIG. 11.

When the fingertip that has been gripped and tightened is loosened after the firing, the power transmission device is restored by the restoring force of the energy stored in the springs 19, 22, 23 deformed by the pulling of the trigger 8 around the rotating shaft 32. Returns to the condition before the trigger 8 was pulled. Along with this, since the pressing force by the power transmission device is eliminated, the leaf spring 30 and the button 31 of the switch 29 for firing and discharging and the button 27 of the rotary switch 28 are also restored to the state before the trigger 8 is pulled. Then, by pulling the trigger 8 again, the next firing process can be started. By repeating this, continuous firing becomes possible. In this embodiment, eight magazines 60 are arranged in line in the magazine part 4 and eight signal bullets are pre-loaded therein, so that a maximum of eight bullets can be fired. Since this set 1 is planned to be used in an emergency, it was designed as a disposable type, but for training, by removing the countersunk screw 3 and replacing the magazine part 4 with an assembly,
It can be used as long as the battery 10 has a life. Although the cost increases, if the battery is designed to be replaced, the life of the grip portion 2 is further extended.

FIG. 12 is a circuit diagram showing an operating mechanism of the set 1. SW1 in the figure is a switch 15 for safety release, which is a key member of the safety release mechanism. By pulling out the safety pin 41 to make the safety plug 13 free and pulling it out, the SW1 is in the safety release state of normally open to closed, and the preparation for firing is completed.

In FIG. 12, RSW is a rotary switch 28 of the power distribution mechanism. When the trigger 8 is pulled, the arm 1 of the trigger 8
8 rotates the triggers 20 and 21 in conjunction with each other, and the trigger 21 pushes up the button 27 of the rotary switch 28. The rotation of the trigger 21 stops when it is fully pushed up, but at this time, the rotary switch 28 selects the terminal of the leg of the ignition ball of the signal bullet that should carry the ignition current, and the preparation for the second stage of firing is completed. To do.

SW2 in FIG. 12 is a switch 29 of the firing and discharging mechanism. Even if the interlocking of the trigger 21 is stopped, if the trigger 8 is further pulled, the trigger 20 continues to rotate interlockingly, pressing the button 31 via the leaf spring 30 of the switch 29 to switch on the switch 29. Looking at this situation in FIG. 12, the switch 29 for firing and discharging represented by SW2.
Is normally open (open between terminals C and NO, closed between terminals C and NC), and when the switch 29 is turned on, the area between C and NO is closed, and the power source E, the transistors Tr, the same Tr, the resistor Cr, and the switch SW2 C
-NO, the resistor Ra, and C-NO of the switch SW1 form a primary closed circuit, and a current flows from the power source E. In this closed circuit, the capacitor C is used until the current flows.
Although the resistance of r is zero, the resistance increases as the charge accumulates, reaches saturation and reaches infinity, and the current flow stops. When a current flows through this primary closed circuit, the two transistors Tr have the directionality shown by the arrows, so that the power source E, the transistors Tr and Tr, the rotary switch RSW, the interface IF, and the resistor Rn (n =
Current flows in a secondary closed circuit between C-NO of the interface IF, the rotary switch RSW, and the switch SW1. Rn is a resistance of the Pt wire of the bridge of the ignition ball of the signal bullet, and when a current flows through the bridge, the Pt wire burns and ignites the ignition ball. The propellant is burned by the thermal energy of this ignition, and the generated high-temperature and high-pressure gas emits a signal bullet. The IF is an interface connector 12 of the grip part 2 and the magazine part 4.
(The grip portion 2 side is a plug, and the magazine portion 4 side is an acceptor).

When the fingertip that has been gripped is released after the firing is finished, the power transmission mechanism returns to the state before the trigger 8 is pulled by the restoring force of the energy stored in the springs 19, 22 and 23, and the next Although it is possible to move to the firing stroke at any time, if the firing interval is long, the battery 10 of the power source E may be discharged. This is because the terminal in which the Pt wire is cross-linked may be deformed due to combustion, or the combustion residue may adhere to cause a short circuit. In order to prevent this, it is necessary to turn off the primary closed circuit and make the charge accumulated in the capacitor Cr zero in order to prepare for the next firing posture. Therefore, at the stage in which the fingertip that grips the grip 2 is loosened and the power transmission mechanism returns to the state before the trigger 8 is pulled, C-NO of SW2
Turn off between (Normal Open), C-NC
It is only necessary to turn on between (Normal Close).
By doing so, the primary closed circuit is turned off, so that no current flows in the secondary closed circuit including the ignition ball, so that there is no unnecessary discharge of the power source E. At the same time, C-NC of switch SW2
(Normal Close) is turned on, and a discharge integration circuit of a third-order closed circuit composed of the capacitor Cr, the resistor Rb, and the switch SW2 is formed, and the capacitor C is formed.
The charge accumulated in r is absorbed by the resistor Rb. That is, when returning to the stage before the button 31 of the ignition / discharge switch 29 is pressed, the C-NC (Normal) of the switch SW2 is returned.
By turning on the Close), the charge accumulated in the capacitor Cr becomes zero, and the next firing posture can be prepared. The next firing stroke can be started by refastening the loosened fingertip and pulling the trigger 8. This operation is repeated for rapid fire.

However, one of the triggers is a power distribution mechanism that stops rotation by selecting the terminal of the ignition ball of the signal bullet that should send the ignition current, and when the trigger is further pulled, the trigger of the power distribution mechanism remains stopped, other One trigger keeps rotating and turns on the ignition switch of the firing and discharge switch, burns the propellant and ignites the signal bullet, and loosens the trigger after the end of firing The ignition switch is off The discharge switch is turned on to prevent unnecessary discharge of the power source due to a short circuit in the ignition ball, and to form a discharge circuit that eliminates the charge accumulated in the capacitor of the ignition circuit for the next firing to zero. , A board on which the elements forming the circuits for power distribution, ignition and discharge are assembled, a connector for controlling the interface with the magazine part, and a grip part composed of a power source, and (c) and the magazine part and the grip part are A life-saving signal rapid fire set consisting of a rubber bag that tightly seals these in a connected state.
