Description

The present invention relates to a portable restraint network deployment device .

  In the present invention, the ignition electronic circuit is, for example, an ignition circuit that can be immediately energized in a net deploying gas generator for a net deployable security device, various energization operating devices that are activated by similar energization, that is, industrial Of electric detonators used for detonation of explosives, etc., ignition balls used for ignition of fireworks, etc., electric ignition pyrotechnics such as automobile pyrotechnics used for starting automobile safety devices, An ignition circuit and an ignition device used for a device that operates by energization such as an ignition tool.

For example, a gas generator for deploying a net of a conventional portable restraint net deploying device (see, for example, Patent Document 1) uses an ignition circuit using an alkaline dry battery and a self-returning switch.
Alkaline batteries are inevitably deteriorated due to natural discharge due to their performance. On the other hand, the net deployment type security device is required to have an emergency response that can deploy the net constantly and instantaneously when the switch is turned on. That is, the battery consumption must be monitored and replaced before the battery is exhausted and the power required for the operation of the apparatus is not supplied.

The net deploying gas generator used in the net deployable security device is short-circuited after operation with a certain probability due to its structure. If a short circuit occurs, there is a risk of heat generation or ignition of the battery. Therefore, it is necessary to protect the battery by disconnecting the circuit after the net deployment operation. Due to the nature of security equipment, it is difficult to always protect the two-stage operation of turning off the switch immediately after the network is deployed in the event of an emergency.
For this reason, only self-returning switches (push-button switches, rocker switches, etc. that turn off naturally when you release your hand) can be used as switches, and there are restrictions on the free shape design and operability of the device. .

The gas generator part for net deployment of the net deployment type crime prevention device has the same principle as what is generally called an electric ignition type pyrotechnic. A conventional ignition circuit / ignition device of an ignition method for an electric ignition type pyrotechnic product generally includes a capacitor-type electric igniter for blasting in consideration of carrying (for example, see Non-patent Document 1, Patent Document 2, and Patent Document 3). ) Is used.
In this method, DC power of a battery serving as a power source is temporarily converted to AC by an oscillation circuit, boosted by a ton lance, returned to DC by a rectifier, and charged and stored in a high withstand voltage capacitor. At the time of ignition, the electric power charged in this capacitor is connected to a pyrotechnic circuit and discharged at a stroke to ignite the pyrotechnic.
JP 2007-107863 A Japanese Patent No. 402613 Japanese Examined Patent Publication No. 6-92880 JIS M2505: 1994

However, in the capacitor type ignition circuit / ignition device, it takes several seconds to several tens of seconds to charge the capacitor, and if a pyrotechnic is immediately ignited for some reason, a time delay occurs. In addition, it is not suitable for applications that require quick response, such as a net deployment type security device.
Moreover, in order to prevent the start-up failure of the gas generator for deploying the net due to the natural consumption of the alkaline battery used, the net deployable crime prevention device requires a battery check at least once a month. Necessary and several battery replacements were required during the product life until the expiry date of the gas generator for net deployment of the net deployment type security device.

The battery remaining amount check circuit is generally a circuit in which a load is connected to the battery in a form simulating the current required for ignition, and the quality of the battery is determined from the terminal voltage of the battery at that time.
In this determination circuit, a circuit for supplying a load current necessary for ignition of the gas generator with at least reproducibility, a circuit for generating a reference voltage, and a battery remaining voltage determination by comparing the terminal voltage of the battery with the reference voltage A complicated and highly accurate circuit, such as a circuit or a circuit that displays the quality of the remaining battery level, is required.
In addition, since the battery check for performing a reliable operation consumes the battery due to the current for checking, there is a problem that the more frequently the battery is checked, the more frequently the battery is replaced.

  In addition, there are some gas generators for deploying nets of net deployable security devices that short circuit after operation due to their structure. If there is a short circuit after operation, current continues to flow while the switch is ON, and there is a risk of heat generation, smoke generation, and explosion of the battery. For this reason, there is a problem that only a self-returning switch such as a push button switch or a tact switch can be used.

The present invention has been made by paying attention to the prior art as described above, and its purpose is to withstand storage for a long period of time and without the need for long-term battery replacement. An object of the present invention is to provide a portable restraint net deployment device including an ignition electronic circuit that can be energized.
Another object of the present invention is that it is possible to protect the power supply even if a current-carrying operation device such as a gas generator for net deployment or an electric ignition type pyrotechnic is short-circuited after ignition and operation, Another object of the present invention is to provide a portable restraint net deploying device having an electronic circuit for ignition that is small in size, excellent in portability, and can be operated instantly.

Another object of the present invention is that, for example, when a switch is turned on, the net deployment gas generator of the net deployment type security device is immediately energized and the net deployment can be activated, and the gas generator is short-circuited after energization. It is another object of the present invention to provide a portable restraint net deployment device including an ignition electronic circuit that can protect against overcurrent of a battery that supplies energization power.

Hereinafter, the present invention will be described based on embodiments shown in the drawings.
(Embodiment 1)
FIG. 1 is a basic circuit diagram of an igniter electronic circuit 110 according to Embodiment 1 of the present invention.
The battery 111 includes a primary battery such as a manganese battery, an alkaline battery, or a lithium primary battery, a secondary battery such as a nickel metal hydride battery, a lead storage battery, or a chargeable / dischargeable lithium secondary battery, depending on the amount of ignition current supplied. Any battery can be used. A lithium primary battery, a lithium secondary battery, a nickel-metal hydride battery, a lead storage battery, or the like having a low internal resistance and a large current capacity is suitable. Furthermore, a lithium primary battery that can be stored for a long period of time and does not require battery replacement in units of several years and has little self-discharge is preferable.

As the voltage of the battery to be used, a battery having a voltage capable of flowing a necessary current to the pyrotechnics or the energizing operation device as a load is used. As for the capacity of the battery, not only the power necessary for the pyrotechnics and energization operating devices as loads, but also a battery with a capacity that takes into account the power that is self-consumed during storage is used.
When the required current and power cannot be obtained with a single battery, a plurality of batteries can be connected in series, parallel, and series-parallel.

As the fuse 112 which is an overcurrent prevention circuit, a fuse such as a claw fuse with a current rating equal to or higher than the ignition current, a tube-filled fuse, a fuse with a lead wire, or the like can be used. It is also possible to use a lead wire that is disconnected by a current higher than the ignition current, such as a fusible link. A fuse with a lead wire having a current rating of 1.5 to 2 times the ignition current and a tube-filled fuse are suitable.
As the ignition switch 113, any of a lever type switch, a slide type switch, a push button switch and the like can be used as long as the current can be cut off and the current at the time of ignition can be supplied before ignition. A push button switch, a lever type switch, a micro switch and the like that are easy to operate are suitable.

Any type of capacitor 114 can be used as long as it has excellent high frequency characteristics. A ceramic capacitor, a multilayer ceramic capacitor, a film capacitor, or the like is suitable. Any charge capacity can be used as long as it can bypass noise caused by electromagnetic induction, such as a mobile phone or a wireless device. A charge capacity of several μF or less is preferable.
It is effective to insert an inductor on one line side or both lines side between the capacitor 114 and the gas generating tool for the net deployment type security device or the pyrotechnic 117. The capacitor 114 has only a parasitic capacitance due to wiring, and the same effect can be obtained by inserting an inductor on one side or both sides.

Considering the cost, attenuation of electromagnetic induction, and the effect of suppressing the initial ignition current, it is preferable to use only the capacitor 114 as shown in FIG. 1, and its electric capacity is preferably about 0.001 μF to 1 μF.
As the connector 115, a two-circuit connector fitted to the connector 116 or two connectors of one circuit can be used.
As the connector 116, a connector that fits with the connector 115 can be used.
A direct connection is also possible without using the connectors 115 and 116.

  For the pyrotechnic 117, a gas generator for deploying a net of a net deployable crime prevention device, an electroignition pyrotechnic, that is, an electric detonator, an ignition ball for smoke fire, and a pyrotechnic for automobile safety can be used. Alternatively, any material can be used as long as it can function by utilizing heat generated by energization of electricity.

Next, the igniter electronic circuit 110 according to the present embodiment will be described.
Since the battery 111 is used as an ignition power source, it is possible to energize the pyrotechnics 117 instantaneously simply by turning on the ignition switch 113. In particular, by using a lithium primary battery as an ignition power source, it is excellent in long-term storage and portability.
When the ignition switch 113 is continuously turned on, even if a short circuit occurs after the operation of the net deployment gas generator or the electric ignition pyrotechnic of the net deployment type security device, the fuse 112 which is an overcurrent prevention circuit In addition, heat generation / rupture of the battery 111 can be prevented.

A similar effect can be obtained by using a viewable link instead of the fuse 112.
When a bimetal is held instead of the fuse 112, the bimetal is activated by the heat generation of the battery 111 to cut the circuit, and abnormal discharge of the battery 111 is suppressed. After cooling, the bimetal is restored, but when the battery 111 generates heat again, the bimetal is activated, so that the battery 111 can be consumed safely in several times.

When a thermistor is used instead of the fuse 112, the electric resistance increases due to the heat generation of the battery 111 and the heat generation of the thermistor itself, and the battery 111 can be consumed while suppressing an excessive current.
If the battery 111 is exhausted and the remaining battery level is extremely low, there is no longer any danger of heat generation, smoke generation, or ignition.

The electronic circuit for igniter 110 according to the present embodiment can be used in a form that is configured on a printed circuit board and incorporated in a net-deployment type security device.
In the present embodiment, the case where the capacitor 114 is provided has been described, but may be omitted.

(Embodiment 2)
FIG. 2 shows a portable restraint network deployment device 100 according to Embodiment 2 of the present invention.
The portable restraint net deployment device 100 according to the present embodiment includes a restraint mesh deployer 1 that ejects the restraint mesh 17 having a plurality of weights 19 attached thereto with the gas pressure of the non-explosive gas generator 21, and the restraint mesh deployer. 1, an operation unit 50 having a switch 65 that drives the non-explosive gas generator 21, and a fixed cup 46 that connects the restraint net deploying device 1 and the operation unit 50.

  In this embodiment, as shown in FIGS. 2 to 4, the restraint net deployer 1 is connected to the first container 10 </ b> A and the second container as in the portable restraint deployer described in JP-A-2006-118845, for example. A container 10 formed by screwing the container 10B, a restraint net 17 that attaches eight weights 19 to the periphery via a string member 18 and restrains a human body accommodated in the container 10 together with the weights 19, and a weight 19 A non-explosive gas generator 21 accommodated in the container 10 for jetting with gas pressure and a lid 20 of the container 10 accommodating the restraint net 17 are formed.

The container 10 includes a first container 10A and a second container 10B that is superimposed on the inside of the first container 10A.
The first container 10A is a container having a substantially funnel shape made of, for example, an ABS resin material or a POM resin material, and has a cylindrical portion 11 protruding from the center portion and eight screws provided at equal intervals on the root portion of the cylindrical portion 11. It has a hole and eight semicircular flow passages 12 that are continuous with the cylindrical portion 11 and branch in eight directions and project outward.
The second container 10 </ b> B includes a cylindrical lid mounting portion 13 provided at the tip, eight semicircular flow paths 14 projecting inward, and a restraint net accommodating portion 15.

The first container 10A and the second container 10B are overlapped so that the eight semicircular flow paths 12 and the eight semicircular flow paths 14 formed in the first container 10A and the second semicircular flow path 14 face each other. They are integrated by screwing four screws from the side into the screw holes. When the first container 10A and the second container 10B constituting the container 10 are combined, eight gas flow paths are formed by the eight semicircular flow paths 12 and the eight semicircular flow paths 14 formed in both the containers. 16 is formed. A weight 19 with a string member 18 attached is inserted and attached to the eight gas flow paths 16.
The lid 20 has a structure in which after the restraint net 17 is accommodated in the second container 10B, the restraint net 17 does not fall off, and can easily fall off from the second container 10B when the restraint net 17 is deployed. Become. The outer shape is substantially disk-shaped and has eight tongues on the side of the lid. The tongue is provided with a small hole in each tongue for fitting into eight protrusions protruding on the outer peripheral wall of the second container 10B, so that the lid 20 and the restraint net 17 do not fall off. ing.

The weight 19 is attached by a string member 18 attached around the restraint net 17. For example, a string member made of polyester and having a diameter of 0.7 mm is used as the string member 18. The weight 19 is made of stainless steel, for example, and is a cylinder having a total length of 28 mm and an outer diameter of 11 mm.
The restraint net 17 is made of, for example, polyester, Kevlar, or polyethylene, and includes a 4 m × 4 m square, a 4 m × 3 m rectangle, or a 3 m × 3 m and 4 m × 4 m octagon. In addition, about half of the total developed area may be formed as a 20 cm square from the vicinity of the center, and the other half may be formed as a 10 cm square. Further, with respect to the mesh width, the inner mesh and the outer mesh may be formed uniformly from the central portion in the entire development area.

Next, as shown in FIGS. 2 to 6, the non-explosive gas generator 21 is filled in the bottomed gas generator tube 22 composed of a cylindrical container opened only on one side, and the gas generator tube 22. The gas generating agent 23 and the igniting agent cup 24, the igniting agent holder 26, the igniting agent 27, the plugging plug 28 with the bridge line, the harness 32, and the heat shrinkable tube 33, and the holder 35. ing.
The gas generator tube 22 is easily broken by the reaction heat and the reaction gas pressure of the gas generating agent 23 which is a non-explosive composition by using a soft metal material such as aluminum, and the weight 19 of the constraining net deploying device 1. Can be transmitted to the weight portion that accommodates. The gas generator tube 22 may be anything as long as it is a soft metal material with good workability. For example, since the gas generator tube 22 has the same shape as an electric detonator using copper, aluminum (for example, Al-6016-0) is used. By using it, the confusingness is removed. The aluminum gas generator tube 22 has alumite treatment on the inner and outer surfaces.

  The gas generator tube 22 is filled with a gas generating agent 23 in a range of 0.1 g to 1.1 g. This gas generating agent 23 uses a low vibration / low noise crushing chemical gunsizer (trade name, manufactured by Nippon Koki Co., Ltd.). This is a non-explosive crushing composition that crushes rocks and the like without the need for a consumption permit in exactly the same procedure as the crushing method using explosives. This non-explosive crushing composition is disclosed, for example, in JP-A-11-029389. The present inventor makes the particle size of the gas generating agent 23 equal in order to achieve the purpose of flying the object (expanding the restraint net) with this gas pressure, not the purpose of crushing the non-explosive crushing composition. Thus, it was found that the variation in gas pressure can be reduced. Further, the dose of the gas generating agent 23 can be changed in accordance with the performance of flying an object.

Next, the gas generating agent 23 will be described.
The ratio of the thermit agent, gas generator, binder and blunting agent constituting the gas generating agent 23 is comprised of 33 parts by weight to 44 parts by weight of cupric oxide and 9 parts by weight to 17 parts by weight of aluminum. The generator is composed of 45 to 55 parts by weight of potassium alum or ammonium alum, the binder is composed of 1.2 to 1.8 parts by weight of vinyl chloride, and the blunting agent is 2.4 to 2.6 parts by weight of calcium stearate. Consists of parts by weight.

  In this embodiment, a thermite agent composed of 11.5 parts by weight of aluminum and 38.5 parts by weight of cupric oxide, a gas generating agent composed of 50 parts by weight of potassium alum or ammonium alum, and previously dissolved in acetone. Put 1.5 parts by weight of vinyl chloride powder used as a binder in the same container, add an appropriate amount of acetone and mix well. When acetone is almost volatilized and solidified, it is granulated with an 8-mesh sieve and dried. After drying, 2.5 parts by weight of calcium stearate as a blunting agent and an appropriate amount of acetone are added and mixed slowly. After acetone is vaporized and solidified, granulation is performed and drying is performed to obtain a gas generating agent 23.

As the gas generating agent 23, a sieving product with 24 Tyler mesh passing 42 Tyler mesh stopping is used. That is, the particle size is adjusted in the range of 0.35 mm to 0.71 mm.
In the gas generator tube 22, a synthetic resin capsule-shaped igniter cup 24 serving as a partition wall is disposed to prevent mixing of the filled gas generant 23 and igniter 27. The igniter cup 24 may be a metal or a non-metal. However, since the metal material has good electric properties, the electric ignition signal does not flow through the bridge line 29 and is consumed by the discharge energy. It is necessary to perform an insulation process (for example, alumite process etc.) since there is a possibility that 27 may be non-ignited.

The igniter cup 24 is a half-cut capsule formed by a thin film having a thickness of 0.1 μm or less, and is inserted into the igniter holder 26. In the igniting agent cup 24 and the igniting agent holder 26, an igniting agent 27 composed of a non-explosive composition and an electric bridge line (for example, a platinum-iridium wire) 29 of an embolus 28 with an electric bridge line are arranged. As the ignition agent 27, boron / cupric oxide = 10 wt% to 20 wt% / 80 wt% to 90 wt% was used.
After inserting the igniting agent holder 26 into the plugging with wire bridge 28, the igniting agent 27 is filled in the range of 0.06 g to 0.13 g and the igniting agent cup 24 is inserted. The gas generating agent 23 is press-fitted into the gas generator tube body 22 filled with the gas generating agent 23, and the crimping portions 30 and 31 are formed at two locations from the outside of the gas generator tube body 22.

FIG. 6 shows a holder 35 which is a part of the non-explosive gas generator 21.
The material of the holder 35 can be iron or stainless steel, but aluminum A5056 is preferable from the viewpoint of weight reduction and cost. The holder 35 includes a screw part 36, a taper part 37, and a holder resin injection part 38. About 3 g of the epoxy resin adhesive 41 is applied to the resin coating part 40 of the non-explosive gas generator 21, the harness 32 of the non-explosive gas generator 21 is inserted into the insertion port 39 of the holder 35, and the plug 28 with a bridge line Until the end portion 28a of the holder contacts the bottom portion 39a of the holder 35. At this time, the application amount of the epoxy resin adhesive 41 only needs to protrude from the holder resin injection portion 38. In addition, the epoxy resin adhesive 41 may be one-packed or two-packed as long as it satisfies the adhesiveness and airtightness with the metal material, but it does not dissolve the leg wire covering resin portion by the solvent, and cures at a low temperature. Therefore, in this embodiment, a two-component room temperature curing type epoxy adhesive is used.

  The function of the holder 35 is to prevent leakage of the generated gas pressure during operation in the attachment to the restraint net deploying device 1 shown in FIG. 2 and the portable restraint net deploying device 100 to which the non-explosive gas generator 21 is attached. is there.

Are attached to the lead wires 62a and 62b. The function of the capacitor 61 is a measure for preventing the ignition tool from being ignited by receiving electromagnetic waves from the outside of the apparatus. Even if it is affected by the electromagnetic waves described above, it has a role of absorbing electricity.
Furthermore, lead wires 64 a and 64 b connected to the switch 65 are attached to the circuit board 58.

  As shown in FIGS. 2, 3, 7, 8, 10, and 11, the switch 65 is provided with an insulating box-shaped container 66 and a contact 68 at the tip, and is connected to a lead wire 64 a. A fixed terminal 67 protruding into the box-shaped container 66, a contact 69 connected to the lead wire 64b and protruding into the box-shaped container 66, a contact 71 at the tip, and a hole 72 at the rear side are provided. 72, a movable terminal 70 inserted through the contact 69 and supported so as to be movable up and down, and a spring that is arranged between the rear end side of the movable terminal 70 and the inner surface of the box-shaped container 66 and presses the movable terminal 70. 73 and a switch button 74 disposed on the rear end side of the movable terminal 70 so as to move up and down from the inside of the box-shaped container 66 to the outside.

  2, 3, 7, 8, 10, and 11, the switch mounting block 55 is located on the rear end side of the operation unit main body 51, and has an outer diameter of the operation unit main body 51. A disk-like standing wall 75 having the same size, a switch plate guide path 76 formed of a rectangular opening provided at a substantially central portion of the standing wall 75, and a rear side so as to cover the switch plate guide path 76 A cylindrical cylindrical portion 77 projecting to the side, an outer cylindrical portion 78 projecting to the rear side longer than the cylindrical portion 77 with the same size as the outer diameter of the operation unit main body 51 so as to cover the cylindrical portion 77, and the cylindrical portion And a space portion 79 formed between the outer periphery of 77 and the inside of the outer cylinder portion 78, and a screw portion 80 provided outside the outer cylinder portion 78.

A switch plate 81 is inserted into the switch plate guide path 76 from the space 79 side through the cylinder portion 77. When the switch plate 81 is inserted into the switch plate guide path 76, the switch button 74 of the switch 65 is inserted to open the ejection circuit 57, and when the switch plate 81 is pulled out, the ejection circuit 57 can be closed.
As shown in FIG. 9, the switch plate 81 is provided with a recess 83 cut out so as to receive the head of the switch button 74 on the lower surface side, and a rectangular parallelepiped plate 82 inserted into the switch plate guide path 76, A ring portion 84 is provided on the base portion of the plate 82 by attaching the ring 85, and a trigger attachment portion 86 is provided on the rear side of the ring portion 84 by providing a hole 87.

The O-ring 85 is slightly larger in diameter by, for example, about 0.5 mm than the inner diameter of the cylindrical portion 77 so that the O-ring 85 is compressed and inserted when the switch plate 81 is inserted into the switch plate guide path 76. is there. The O-ring 85 is used to determine the pulling load (ease of pulling out) of the switch plate 81 and to measure waterproofing with the cylindrical portion 77.
A trigger member 88 is attached to the hole 87.
As the trigger member 88, for example, a chain is used in which a ball chain made of a phosphorescent resin or a phosphorescent metal is formed into a ring shape using an attachment. Since the trigger member 88 has flexibility, it can be accommodated so as to fill the space 79 after the switch plate 81 is inserted into the switch plate guide path 76. The trigger member 88 may be a chemical fiber as long as it has strength.

  As shown in FIG. 3, after the ejection circuit 57 and the switch 65 are accommodated in the operation unit main body 51, the switch plate 81 to which the trigger member 88 is attached is pushed into the switch plate guide path 76 by pushing the switch button 74. In a state where 81 is pushed in and the ejection circuit 57 is opened, the non-explosive gas generator 21 is inserted from the tip side, and the connector 34 of the non-explosive gas generator 21 and the connector 63 of the ejection circuit 57 are connected. After this operation, the cover 56 is put on the notch 54.

The covering portion 56 has an arc cross section and includes a protrusion 92 that fixes the outer periphery of the upper side of the switch 65. The covering portion 56 is fixed to the notch portion 54 of the operation portion main body 51 by a screw 93.
A cylindrical grip cover 94 formed of an elastic member (elastomer) is put on the operation portion main body 51 to which the covering portion 56 is fixed. The grip cover 94 is provided with unevenness on the outer periphery to prevent slipping. Further, since the grip cover 94 covers the joint portion between the notch portion 54 and the covering portion 56, the grip cover 94 also has a waterproof mechanism for preventing water from entering from the outside.

  As shown in FIGS. 2, 3, 7, 10, and 11, the outer cylindrical portion 78 of the operation portion main body 51 to which the grip cover 94 is attached has a screw portion 90 that is screwed into the screw portion 80 on the inner side. A grip end 89 that is provided and provided with a screw portion 91 on the outside is attached. The grip end 89 is for positioning the grip cover 94 (preventing misalignment), but also has a function for preventing the operator's hand from slipping off the operation portion 50 when the trigger member 88 is pulled.

  As shown in FIGS. 2 and 3, an end cap 95 is attached to the screw portion 91 of the grip end 89 by screwing a screw portion 96 provided inside. The end cap 95 is a safety device for preventing the trigger member 88 housed in the operation unit main body 51 from coming out. The end cap 95 is turned off during use. The end cap 95 is formed of a transparent resin so that light strikes the internal switch plate 81 during storage.

  As shown in FIGS. 2 and 3, the fixed cup 46 includes a hole 47 through which the operation portion 50 is inserted and an annular bulging portion 53 for retaining at the end portion, and a distal end portion of the operation portion main body 51. And a receiving portion 48 on which a box-shaped protrusion 52 for stopping rotation is provided. The fix cup 46 is fixed to the restraint net deployer 1 by screws 49. As shown in FIG. 3, the head of the screw 49 is hidden by the seal 97.

Next, the operation of the portable restraint network deployment device 100 according to the present embodiment will be described.
<Assembly>
First, the non-explosive gas generator 21 is screwed onto the container 10 to assemble the restraint net deploying device 1.
Next, the ejection circuit 57 is fitted into the operation unit main body 51, and the circuit board 58 is coupled with a screw. The switch 65 is fitted and fixed to the operation unit main body 51.
Next, the O-ring 99 is attached to the restraint net deploying device 1. The O-ring 99 is sandwiched when the operation unit 50 and the constraining net deploying device 1 are joined in a later process, and has a sealing function as a waterproof by filling the gap between the two parts.

Next, the switch plate 81 is inserted from the switch plate guide path 76, and the switch 65 is turned OFF.
Next, the non-explosive gas generator 21 of the restraint net deploying device 1 is inserted into the operation unit main body 51 together with the harness 32 and the connector 34, and the fix cup 46 is passed through the operation unit main body 51 to prevent the operation unit main body 51 from rotating. Are attached to the receiving portion 48 of the fixed cup 46, and the fixed cup 46 and the restraining net deploying device 1 are screwed together by a screw 49 to be integrated.
Next, the connector 34 of the non-explosive gas generator 21 and the connector 63 of the ejection circuit 57 are connected. Thereby, the circuits in the apparatus are integrated.

Next, the harness 32 is folded, the notched portion 54 of the operation portion main body 51 is covered with the covering portion 56, and screwed with the screw 93.
Next, the grip cover 94 is attached to the operation unit main body 51.
Next, the grip end 89 is screwed to the operation unit main body 51.
Next, the end cap 95 is screwed onto the grip end 89.

<Operation method>
First, as shown in FIG. 10, when the end cap 95 that is a safety device is removed, the trigger member 88 comes out of the operation unit 50.
Next, the operation unit 50 is gripped, the trigger member 88 is pulled toward the criminal suspect with the restraint net deploying device 1 facing the criminal suspect, and the connected switch plate 81 is pulled out.
Next, the switch 65 is turned on, and electricity flows from the battery 59 to the non-explosive gas generator 21.
Next, the non-explosive gas generator 21 is ignited to generate gas, and the restraint net 17 is deployed toward the crime suspect by the gas pressure.

As shown in FIG. 11, after operation, in the switch 65, the switch button 74 protrudes from the box-shaped container 66 of the switch 65 by the spring 73, thereby preventing the switch plate 81 from being reinserted. Therefore, since it is impossible to reinsert the switch plate 81, misuse of the used product can be prevented.
Further, when the switch 65 is continuously turned on, even if a short circuit occurs after the non-explosive gas generator 21 is activated, the battery 59 can be prevented from being heated and ruptured by the fuse 60 serving as an overcurrent prevention circuit.

Next, a verification test was conducted on the operability with respect to the pulling force of the switch plate 81 in the present embodiment.
The pulling load of the switch plate 81 was set at four levels, and the actual ease of pulling out was verified. The results are shown in Table 1.

  From the results shown in Table 1, when the pull-out load of the switch plate 81 is 40 N or more, a force is applied when pulling out, and a case that is difficult to operate occurs. Therefore, in the pulling-out operation, conditions that can be operated at 35 N or less are optimal. The lower limit is a condition that the plate does not fall off due to its own weight, and is set to 0.2N.

The setting of the pull-out load can be adjusted by a dimensional difference (clearance) between the hole diameter of the cylindrical portion 77 and the O-ring 85 of the switch plate 81. Further, since the pressing force of the switch 65 is extremely small (about 1 N), there is no need to consider it.
In this embodiment, for example, the hole diameter of the cylindrical portion 77 is φ12.5 mm, the outer diameter of the O-ring 85 is φ13 mm, and the O-ring 85 is pressed while being crushed. It has been confirmed that when grease is applied to the hole of the cylindrical portion 77 or the O-ring 85, the pulling load is reduced.

Next, the operability with respect to the length of the trigger member 88 was verified.
An operability verification test was performed on the length of the ball chain constituting the trigger member 88.
The length of the ball chain was verified at 9 levels in increments of 50 mm from 100 mm to 500 mm. (Since the chain is connected in a ring shape, the total length of the pulling portion is half of the above.)
As a result, the optimum length was 150 mm to 450 mm.

Although the chain is ring-shaped, it is easier to operate by “grabbing and pulling” than by pulling it through a finger. If it is long, it is difficult to aim.
In addition, when the length is short, there is a case where the chain is missed. For example, when wearing thick gloves, it is basically difficult to grasp.
On the other hand, if it is long, it is difficult to aim at the end of the chain. However, even if it is long, there is no problem in use when gripping the vicinity of the plate.

Hereinafter, the present invention will be described in detail by way of examples and comparative examples.
Example 1
A first embodiment will be described with reference to FIG.

The resistance of the entire circuit was 1.5Ω including the electric wire connecting the gas generator.

  When the ignition switch 113 was turned on, an average current of 1.8 A flowed through the electric line, and the electric detonator of the pyrotechnic 117 of the gas generator for deploying the net instantly exploded. About 30% of the gas generators for net deployment continued to be energized after the explosion, but before any abnormal heating of the battery 111 occurred, the fuse 112 was disconnected and the battery 111 was protected. .

Here, a description will be given using a circuit such as a conventional net deployment type security device.
The battery 121 uses a 006P type alkaline dry battery, the ignition switch 123 uses a self-returning tact switch (125V5A), and the electromagnetic wave countermeasure capacitor 124 uses a multilayer ceramic capacitor (0.1 μF50 WV). 2P connectors 125 and 126 are used to connect the net deployment gas generator of the net deployment type security device, and the pyrotechnic 127 of the net deployment type gas generator for net deployment type security device includes a gas generator (special FIG. 20) of Japanese Utility Model Publication No. 2007-107863 was used. The resistance of the circuit on the gas generator side was 1.5Ω including the electric wire connecting the gas generator.

A push button switch (125V5A) is used for the battery level check switch 128 of the battery 121, a green light emitting diode is used for the battery level display LED 129, and the driving semiconductor 130 of the battery level display LED 129 is A transistor was used.
The determination of the remaining battery level is performed by appropriately dividing the terminal voltage of the lowered battery generated by energization through the load resistor 136 and the switch 128 by the voltage dividing resistors 132 and 133 and supplying the divided voltage to the input of the arithmetic circuit 131. . The arithmetic circuit 131 compares the reference voltage created by the current limiting resistor 134 and the constant voltage element 135 with the supply voltage. If the remaining battery level is sufficient, the driving semiconductor of the remaining battery level display LED 129 is turned ON. The battery level display LED 129 is turned on.
In the circuit of Comparative Example 1, the battery needs to be replaced due to the consumption of the 006P type alkaline battery.

Here, an example of a capacitor-type blasting electric igniter will be described.
A gas generator was used as an igniter for JIS M 2505: 1994 capacitor-type blasting electric igniter 50 shots (500V8μF rating) and a net deployment gas generator for a net deployment type security device. The resistance of the entire circuit was 5Ω including the electric wire connecting the gas generator.
