In the present embodiment, the cylindrical body has a single fixed long shape, but it is also possible to use a telescopic method. When the conducting wire 78 is connected to the conducting wire 13 of the restraint net ejection portion 1A, the initiator 10, the operation switch 76, and the battery 77 are connected in series.

As shown in FIGS. 18 and 19, the pressure suppressing portion 1 </ b> C includes a connecting annular portion 82 a having a screw portion 82 b that is screwed to a screw portion 75 of the pressure suppressing rod 72 of the handle portion 1 </ b> B, and a connecting annular portion 82 a. And an annular portion 82c for pressure control connected through a plurality of stays 82d.
The pressure suppressing part 1C has a function of pressing a suspicious person and a function of protecting the restraint net ejection part 1A. Further, the pressure suppressing part 1C is a conical shape having an outer diameter of 230 mm made of, for example, an aluminum material. When pressing the suspicious person, even if the suspicious person grasps the pressure suppressing part 1C and resists it, the size is difficult to transmit the force to the operation side.・ It has a shape.

As described above, the portable restraint network deployment device 1 according to the present embodiment can be obtained.
(Operation)
Next, operation | movement of the portable restraint network expansion | deployment apparatus 1 which concerns on this embodiment is demonstrated.
When the operation switch 76 is turned on, an electrical signal is sent to the initiator 10 via the lead 78 by the ON signal of the operation switch 76, and the heat generating part 11 of the initiator 10 ignites the ignition agent 14 and ignites the gas generating agent 15.

Next, when the gas pressure accompanying combustion of the gas generating agent 15 increases and reaches a predetermined value, the rupturable plate 25 is broken, and the generated gas is cooled by the molded filter 27 accommodated in the filter cup 28 via the spacer 26. Filtered and flows into the container 35.
Next, the generated gas that has flowed into the container 35 is divided into eight gas flow paths 49 from the gas flow path 39 formed between the cylindrical portion 36 and the cylindrical portion 42 of the container 35, and the eight gas flows. The weight portions 30 respectively disposed at the weight outlets 49 a of the flow path 49 are ejected to the outside of the container 35.

Next, along with the ejection of the weight part 30, the restraint net accommodation lid 50 is removed and the restraint net 31 is deployed.
Here, as shown in FIG. 14, the weight part 30 is attached to the restraint net 31 via the string members 32 at the four corners of the rectangular restraint net 31 and the midpoints of the respective sides, and the container 35 with the apex of the container 35 as the base point. Eight weight spouts 49a are provided at the points obtained by dividing 35 into eight parts, and the weight part 30 located at the midpoint of the upper side of the restraint net 31 is provided at the apex of the container 35 as shown in FIG. The mark 40b for accommodating in 49a is provided.

Since the restraint net 31 has a rectangular shape, the restraint net 31 can be developed into a rectangular shape by having diagonal lines of the restraint net 31 located at the corners of the ceiling and walls and the walls and floors in the building. Thus, the restraint net 31 can be efficiently deployed.
Therefore, when assembling the portable restraint net deployment device 1 according to the present embodiment, the weight part 30 located at the midpoint of the upper side of the restraint net 31 is inserted into the weight spout 49a according to the mark 40b, and the remaining weight part 30 is inserted. The above-described effects can be achieved simply by sequentially inserting into the weight outlet 49a.

  Further, the weight spout 49a is provided at a point obtained by dividing the container 35 into eight equal parts with a point shifted from the apex of the container 35 by minus 22.5 degrees or plus 22.5 degrees along the edge of the container 35. In this case, the mark 40b is moved in accordance with the displacement of the weight outlet 49a, and when provided at a point shifted by minus 22.5 degrees, the weight part 30 located at the left end of the upper side of the restraint net 31 is used. If it is provided at a point shifted by +22.5 degrees, it is used as a mark for inserting the weight portion 30 located at the right end of the upper side of the restraint net 31.

  As described above, according to the present embodiment, the restraint net ejecting portion 1A and the pressure suppressing portion 1C are attached to the handle portion 1B serving as a pressure suppressing rod, so that even a guard, a police officer, or a general person can carry it sufficiently. is there. In addition, the restraint net ejecting portion 1A is attached to the tip of the handle portion 1B, which is a suppression rod of a predetermined length, and the restraint net ejecting portion 1A is protected by the restraining portion 1C. The distance can be taken, and the flying distance of the restraint net 31 can be increased by the length of the handle portion 1B serving as a control rod. The restraint net 31 can be deployed with a margin, and the probability of restraint is increased. .

For example, when the overall length of the handle portion 1B serving as a pressure-control rod is 1.6 m, it can be used as a length that can be sufficiently routed even in a relatively narrow place such as a school corridor.
Further, by making the pressure-control rod 72 of the handle portion 1B extendable, it can be set to an arbitrary length, so that the degree of freedom during storage and use increases.
Moreover, it is possible to hold down a suspected crime by the suppression part 1C protecting the restraint net ejection part 1A. By adopting such a conical shape and size, even if the pressure suppressor 1C is grasped by a crime accused person, it is difficult for force to be transmitted to the operation side, and the possibility that the operation side is exposed to danger is reduced. Furthermore, since the pressure suppressing portion 1C is structured to be fastened by the pressure suppressing rod 72 and a screw, an object having an arbitrary shape can be easily attached to the handle portion 1B.

  The pyrotechnic igniter (gas generating part) of the restraint net ejection part 1A is a non-explosive initiator 10 and is not subject to legal regulations such as the High Pressure Gas Safety Law or the Explosives Control Law, Anyone other than a specific person can use it. Since the initiator 10 can be electrically operated, it can be easily attached to the tip of a long pressure control rod only by adjusting the lengths of the conducting wires 13 and 78. In addition, in the form which attaches to a long pressure suppression rod, when compressed gas is used, a structure becomes complicated in handling of a gas flow path.

  In the present embodiment, the annular portions 82a and 82c are connected by the stay 82d as the pressure suppressing portion 1C. However, the present invention is not limited to this. For example, as shown in FIGS. 34 and 35, the annular portion 82a has a piercing shape. If it is set as the suppression part 1C 'provided with the suppression rod 82e, it can be used also as a piercing crotch. Further, as shown in FIGS. 36 and 37, a pressure-suppressing portion 1C ″ obtained by combining the pressure-suppressing portion 1C used in the present embodiment and a stab-shaped control rod 82e may be used. It is possible to have the functions of the pressure suppressing portion 1C and the pressure suppressing portion 1C 'shown in FIGS.

(Experiment)
Next, the portable restraint network deployment device 1 according to the present embodiment will be described using Experimental Examples 1 to 6.
(Experimental example 1)
As shown in FIG. 26, using the portable restraint net deployment device 1 according to the first embodiment, the handle portion 1B is sandwiched and fixed by the fixing jig 102 attached to the gantry 101 so as to be horizontal with the ground surface. It was set at a height of 1.5 m. Restraint net ejection portions 1A having different ejection angles were prepared, and the trajectory of the weight at each ejection angle was analyzed. In the analysis, the video camera 103 is installed at a position 5 m vertically away from the position 2.5 m from the gantry in the ejection direction of the restraint net 31, and from the start of the ejection of the restraint net 31 until the restraint net 31 falls to the ground surface. Images taken in between were performed with a video analysis device. The object of analysis was the weight portion located at the top and bottom in the image. The size of the restraint net 31 was a 3 m × 3 m square, and the mesh width was fixed at 12.5 cm. In addition, since the restraint net 31 is vertically and laterally symmetric and the weight part 30 is equally arranged on the circumference of 360 degrees, the degree of deployment of the restraint net 31 obtained by the trajectory of the weight part 30 depends on the side surface. Since the analysis from the front and the analysis from the front are the same, the analysis was made in one direction from the side.

  The result is shown in FIG. When the jet angle is 0 degree on the horizontal axis of the restraint net jet part 1A, it was confirmed that the smaller the jet angle, the shorter the flight distance, and the larger, the longer the flight distance. In addition, from 20 degrees to 75 degrees, 90% or more of the restraint net 31 is expanded with respect to 3 m of the maximum expansion in the vertical direction. On the other hand, when the ejection angle is 80 degrees, the flight distance reaches 7 to 8 m, but the restraint net 31 has fallen to the ground before it is sufficiently deployed to cover the entire target body (for example, a human). Was confirmed.

In this experiment, the pressure in the gas flow path in the container 35 due to the gas generated from the initiator 10 was measured.
The result is shown in FIG. The pressure behavior begins to increase 0.0346 seconds after the actuation switch 76 is pressed, shows a maximum pressure of 1.1 MPa after 0.0351 seconds, and returns to atmospheric pressure after 0.038 seconds (all times This is the elapsed time since the operation switch 76 was pressed).

Here, in conducting the following experiment, the distance between the target body (male adult 1.7 to 1.8 m) and the portable restraint network deployment device 1 is defined according to perception (reference: published by Asakura Shoten / human) Tolerance handbook).
<< Case 1 >> = Social distance = Short distance = Difficult distance to touch the opponent In this case 1, it is assumed that the target body attacks or the surrounding area is attacked.

According to the reference, the distance that is difficult to touch the opponent is 1.22 m to 2.13 m in direct view and 2.13 m to 3.66 m in non-direct view. Therefore, the average of these distances is taken to be 2.5 m.
《Case 2》 = Public distance = Long distance = Distance that can be avoided without being involved with the other party In this case 2, it is assumed that the target is trying to escape or is attacking the surroundings .

According to the reference, the distance that can be escaped and prevented without being involved with the opponent is set to be 3.66 m to 7.62 m in direct view and 7.62 m or more in non-direct view. Therefore, the average of the direct viewing distance is taken as 5.6 m.
(Experimental example 2)
The ejection angle was set to 50 degrees using the portable restraint net deployment device 1 according to the first embodiment. FIG. 29 shows the result of measurement of the unfolded shape of the restraint net 31 until the restraint net 31 lands on the ground in the same measurement situation as in Experimental Example 1.

  In the restraint net 31, after pressing the operation switch 76, 0.2 seconds later, the weight part 30 located at the bottom reaches the position of 1.3 m from the portable restraint net deployment device 1, and remains almost unchanged. The uppermost weight part 30 showed the maximum height after 0.4 seconds. That is, after 0.4 seconds, the restraint network 31 shows the maximum development. The uppermost weight portion 30 after 0.4 seconds passed was landed at a position of 3.8 m from the portable restraint net deployment device 1 after 1 second while drawing a parabola.

  From this, when the target body is on the ground, the range in which the restraint net 31 can be covered without causing the weight part 30 to collide is 1.3 m or more from the portable restraint net deployment device 1, Safety can be ensured when the target body exists at the above-mentioned social distance (short distance = 1.78 m to 3.22 m). At that time, when the restraint net 31 starts to cover the target body, assuming that the target body having a height of 1.75 m exists at the midpoint (2.5 m) of the social distance, the deployment of the portable restraint net is performed. It is 0.6 seconds after the operation switch 76 of the apparatus 1 is pressed.

(Experimental example 3)
The ejection angle was set to 75 degrees using the portable restraint net deployment device 1 according to the first embodiment. FIG. 30 shows the measurement results of the unfolded shape of the restraint net 31 until the restraint net 31 lands on the ground in the same measurement situation as in Experimental Example 1.
In the restraint net, after pressing the operation switch 76, 0.3 seconds later, the weight part 30 located at the bottom landed at the position of 3.7 m from the portable restraint net deploying device 1 and stopped at almost the same position. The upper weight part 30 showed the maximum height after 0.5 seconds. That is, after 0.5 seconds, the restraint network 31 shows the maximum development. After the elapse of 0.5 seconds, the uppermost weight portion 30 landed at a position of 6.6 m from the portable restraint net deployment device 1 after 1 second while drawing a parabola.

  From this, when the target body is on the ground, the range in which the restraint net 31 can be covered without causing the weight part 30 to collide is 3.7 m or more from the portable restraint net deployment device 1, Safety can be ensured when the target body is present in the public distance (long distance = 4.88 m to 6.32 m). In addition, the time when the restraint net 31 starts to cover the target body at that time is assumed that a target body having a height of 1.75 m exists at the midpoint (5.6 m) of the above-mentioned social distance. It is 0.6 seconds after the operation switch 76 of the apparatus 1 is pressed.

(Experimental example 4)
The ejection angle was set to 20 degrees using the portable restraint net deployment device 1 according to the first embodiment. FIG. 31 shows the measurement results of the unfolded shape of the restraint net 31 until the restraint net 31 lands on the ground in the same measurement situation as in Experimental Example 1.
In the restraint net 31, after pressing the operation switch 76, the weight part 30 located at the bottom after 0.2 seconds has landed at a position of 0.6 m from the portable restraint net unfolding device 1, and remains almost unchanged. The uppermost weight part 30 showed the maximum height after 0.3 seconds. That is, after 0.3 seconds, the restraint network 31 shows the maximum development. The uppermost weight portion 30 after 0.3 seconds passed was landed at a position of 2.4 m from the portable restraint net deployment device 1 0.9 seconds later while drawing a parabola.

  From this, when the target body is on the ground, the range in which the restraint net 31 can be covered without causing the weight part 30 to collide is 0.6 m or more from the portable restraint net deployment device 1, Safety can be ensured when the target body exists at the above-mentioned social distance (short distance = 1.78 m to 3.22 m). In addition, assuming that a target body having a height of 1.75 m exists at the closest point (1.78 m) of the above-mentioned social distance, the time for the restraint net to start covering the target body at that time is as follows.

Next, the restraint net ejecting portion 3A where the restraint net 31 is developed is removed from the adapter 3D.
At this time, in order to extract the protrusions 55 a, 55 b, 55 c locked in the locking groove 90, the plug 52 A is pressed in the direction of the adapter 3 D, and the tip of the plug 52 A is elastic member 93 via the partition member 92. , The plug 52A is rotated and the projections 55a, 55b, and 55c are moved along the lateral groove 89, and the projections 55a, 55b, and 55c abut against the wall surface of the groove 88. When the plug 52A is released when the movement is prevented, the plug 52A is pressed in the direction of the insertion port of the first connecting portion 85 via the partition member 92 by the restoring force of the compressed elastic member 93, and the protruding portion 55a. , 55b and 55c are removed from the insertion port of the first connecting portion 85 while moving along the groove portion 88, and the restraining force on the plug 52A of the restraint net ejection portion 3A by the adapter 3D is released. That. Therefore, the restraint net ejection part 3A can be easily pulled out in the opposite direction to the adapter 3D.

Next, a new restraint net ejection part 3A is attached to the adapter 3D.
This operation is performed in the same manner as the attachment of the restraint net ejection portion 3A to the first connection portion 85 of the adapter 3D described above.
Thus, in this embodiment, after using the restraint net | network ejection part 3A, the used restraint net | network ejection part 3A can be removed from adapter 3D, and a new restraint net | network ejection part 3A can be attached easily.

  As described above, according to the present embodiment, since the pressure suppressing portion 3C is attached to the handle portion 3B serving as a pressure suppressing rod and the restraint net ejection portion 3A is attached via the adapter 3D, a security guard, a police officer, or a general person But you can carry it well. In addition, since the restraint net ejection part 3A is attached to the tip of the handle part 3B, which becomes a predetermined length of the control rod, and further, the restraint net ejection part 3A is protected by the suppression part 3C. The distance can be taken, and the flying distance of the restraint net 31 can be increased by the length of the handle portion 3B serving as a suppression rod. The restraint net 31 can be deployed with a margin, and the probability of restraint is increased. .

Further, for example, when the overall length of the handle portion 3B serving as a pressure suppressing rod is 1.6 m, it can be used as a length that can be sufficiently routed even in a relatively narrow place such as a school corridor.

Moreover, it is possible to hold down a criminal suspect by the suppression part 3C protecting the restraint net ejection part 3A. By adopting such a conical shape and size, even if the suspected criminal 3C is gripped by the crime suspect, it is difficult for the force to be transmitted to the operation side, and the possibility that the operation side is exposed to danger will be reduced. Further, since the pressure suppressing portion 3C is structured to be fastened by the pressure suppressing rod 72 and a screw, an object having an arbitrary shape can be easily attached to the handle portion 3B.

  The pyrotechnic igniter (gas generating part) of the restraint net ejection part 3A is a non-explosive initiator 10 and is not subject to regulations such as the High Pressure Gas Safety Law or the Explosives Control Law, Anyone other than a specific person can use it. Since the initiator 10 can be electrically operated, it can be easily attached to the tip of a long pressure control rod only by adjusting the lengths of the conducting wires 13 and 78. In addition, in the form which attaches to a long pressure suppression rod, when compressed gas is used, a structure becomes complicated in handling of a gas flow path.

According to this embodiment, the same operational effects as those of the first embodiment can be achieved.
