(Operation)
Next, operation | movement of the portable restraint network expansion | deployment apparatus 1 which concerns on this embodiment is demonstrated.

First, the seal is removed, and the guard cover 76 is opened so that the activation push button 72 can be ejected from the restraint net 31.
Next, the start push button 72 is turned on. As a result, the firing circuit 79b is activated, the BAT (+) of the battery 75 and the EXP (+) of the initiator 10 are short-circuited, and the element connected between the EXP (+) and EXP (−) of the initiator 10 is energized. In response to the ON signal of the activation push button 72, an electrical signal is sent to the initiator 10 via the conductor 82, and the heat generating portion 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 filtered through the spacer 26 through the molded filter 27 accommodated in the filter cup 28. 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 portions 30 are attached to the restraint net 31 via the string members 32 at the four corners of the rectangular restraint net 31 and the midpoint of each side. The container 35 is provided with eight weight outlets 49a at a point obtained by dividing the container 35 into eight equal parts with the vertex of the container 35 as a base point. The vertex of the container 35 is shown in FIGS. 1, 3, and 11 to 13. As shown, a mark 40b is provided for accommodating the weight portion 30 located at the midpoint of the upper side of the restraint net 31 in the weight outlet 49a.

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.

Next, the restraint net ejecting portion 1A in which the restraint net 31 is developed is removed from the adapter 1C.
At this time, in order to extract the protrusions 55 a, 55 b and 55 c locked in the locking groove 90, the plug 52 is pressed in the direction of the adapter 1 </ b> C, and the tip of the plug 52 is elastic member 93 via the partition member 92. When the movement is blocked, the plug 52 is rotated, and the protrusions 55a, 55b, and 55c are moved along the lateral groove part 89, and the protrusions 55a, 55b, and 55c abut against the wall surface 88d of the groove part 88. When the plug 52 is freed when the movement is prevented, the restoring force of the compressed elastic member 93 presses the plug 52 through the partition member 92 in the direction of the insertion port of the first connecting portion 85, and the protruding portion 55a, 55b, and 55c are extracted from the insertion port of the first connecting portion 85 while moving along the groove portion 88, and the restraining force on the plug 52 of the restraint net ejection portion 1A by the adapter 1C is released. Therefore, the restraint net ejection part 1A can be easily pulled out in the opposite direction to the adapter 1C.

Next, a new restraint net ejection part 1A is attached to the adapter 1C.
This operation is performed in the same manner as the attachment of the restraint net ejection portion 1A to the first connecting portion 85 of the adapter 1C described above.
Thus, in this embodiment, after using the restraint net | network ejection part 1A, the used restraint net | network ejection part 1A can be removed from the adapter 1C, and a new restraint net | network ejection part 1A can be attached easily.

  In the portable restraint net deployment device 1 according to the present embodiment, it is possible to confirm with the indicator 74 that the restraint net 31 can be ejected by pressing the check button 73. When the check button 73 is turned on, the power supply confirmation circuit 79c operates, a voltage is applied from the BAT (+) of the battery 75 to the MOS FET 79d, and the MOS FET 79d is turned on. The MOS FET 79d is turned ON, the operational amplifier 79e, the shunt regulator 79f, and the GND of each resistor are short-circuited with the BAT (−) of the battery 75, and the operation is started. A current for checking the power flows from the BAT (+) of the battery 75 toward the BAT (−) via each resistor, and the current at this time is about 200 mA when the battery 75 is rated at 9V. By consuming the current, the voltage of the battery 75 changes from 8.54 to 0 V. When the voltage exceeds 8.38 V, the indicator 74 is turned on. When the voltage is lower than 8.38 V, the indicator 74 is turned off. Therefore, since it can be confirmed in advance whether or not it is in a standby state, it is possible to avoid a situation in which the restraint net ejection portion 1A does not start up when actually used. Here, the MOS FET 79d actually changes the signal of the check button 73 into a current for power supply confirmation. The operational amplifier 79e is a comparison IC for confirming the remaining amount of the battery 75 by voltage. The shunt regulator 79f is an IC that generates a reference voltage used for comparison with the operational amplifier 79e.

(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. 29, using the portable restraint net deployment device 1 according to the first embodiment, the operation unit 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 activation push button 72 is pressed, shows a maximum pressure of 1.1 MPa after 0.0351 seconds, and returns to atmospheric pressure after 0.038 seconds (time is All are the elapsed time since the start push button 72 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 is attacking or is attacking the surroundings.

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.

The uppermost weight portion 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 start push button 72 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.

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 start push button 72 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. 34 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 start push button 72, 0.2 seconds later, the weight part 30 located at the bottom reaches the position of 0.6 m from the portable restraint net unfolding device 1 and stops at almost the same position. The uppermost weight portion 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. It is 0.6 seconds after the start push button 72 of 1 is pressed.

(Experimental example 5)
Using the portable restraint net deployment device 1 according to the first embodiment, the ejection angles were set to 20 degrees and 30 degrees. As shown in FIG. 35, it was fixed to the ceiling at a height of 3 m from the ground surface. In this situation, the deployment speed was analyzed according to the accommodation method of the restraint net 31 (three types: FIGS. 26 to 28). In the analysis, the video camera 103 is installed at a position of 1.5 m in the horizontal direction at a distance of 2 m from the portable restraint net deployment device 1 until the restraint net 31 falls to the ground surface from the start of the ejection of the restraint net 31. Images taken between the two were performed with a video analysis device. The object of analysis was the weight portions 30 located at the left and right ends in the image, the restraint net 31 was an octagon of 3 m × 3 m, and the mesh width was fixed at 12.5 cm. In addition, since the restraint net is vertically and horizontally symmetrical and the weight part 30 is equally arranged on the circumference of 360 degrees, the degree of deployment of the restraint net 31 obtained from the trajectory of the weight part 30 is determined from 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 evaluation of the deployment speed was performed based on the time required for the restraint network 31 to deploy to a certain standard and its height. The reference was a point indicating development corresponding to 90% of the restraint net 31 (expansion diameter 2.7 m = 3 m × 0.9).

The result is shown in FIG. 90% of the time showing the deployment was the earliest, and the deployment method at the highest position was the accommodation method 3 regardless of whether the ejection angle was 20 degrees or 30 degrees.
