  In this embodiment, as shown in FIGS. 1 to 3, 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 attachment portion 13 provided at the tip, eight semicircular flow paths 14 projecting inward, and a restraint net accommodation 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 FIG. 1 to FIG. 5, the non-explosive gas generator 21 is filled in the bottomed gas generator tube 22 made of a cylindrical container opened on only 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 thermite agent, gas generator, binder and blunting agent constituting the gas generating agent 23 is such that the thermite agent is composed of 33 to 44 parts by weight of cupric oxide and 9 to 17 parts by weight of aluminum, and the gas generating agent is potassium. It consists of 45 to 55 parts by weight of alum or ammonium alum, the binder consists of 1.2 to 1.8 parts by weight of vinyl chloride, and the blunting agent consists of 2.4 to 2.6 parts by weight of calcium stearate.

  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 a plug 28 with an electric bridge line are arranged. As the ignition agent 27, boron / cupric oxide = 10 to 20% by weight / 80 to 90% by weight 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.

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. Taking this into consideration, in this embodiment, a two-component room temperature curing epoxy adhesive was used.

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

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. 10, after the 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.

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.
