従来の拘束網展開装置は、一時的な犯人拘束装置として、天井裏に配置される捕捉網・投網器が知られている(例えば、特許文献1参照)。
特許文献1では、中空円筒状あるいはリング状の折り畳まれた捕捉網用の収容室(28)からスリーブ(29)が、作用範囲(20)の中心軸線に対して漏斗状に下向きに突出して設けられている。そして、このスリーブ(29)は収容室(28)から捕捉網を軸方向に引出し径方向に張るための加速錘を案内するためおよび反応ガスをせき止めるために使用するとしている。
A conventional restraint net deployment device is known as a temporary criminal restraint device, such as a capture net / thrower placed behind the ceiling (for example, see Patent Document 1).
In Patent Document 1, a sleeve (29) is provided so as to protrude downward in a funnel shape with respect to the central axis of the operating range (20) from a hollow cylindrical or ring-shaped trapping net storage chamber (28). It has been. The sleeve (29) is used to guide the acceleration weight for pulling out the trapping net in the axial direction from the accommodating chamber (28) and to stretch the reaction gas, and to stop the reaction gas.

また、特許文献1には、捕捉網の引き出しおよび折り広げに関して設置する天井などの障害物を突破あるいは破壊するのに、火工技術的に発射される加速錘の発射エネルギでも十分に足りることが開示されている。
特表2000−503142号公報(第7頁、第9頁、第10頁、図3)
Further, Patent Document 1 discloses that the acceleration energy emitted by the pyrotechnics is sufficient to break through or destroy obstacles such as the ceiling installed for the extraction and folding of the trapping net. It is disclosed.
JP 2000-503142 A (page 7, page 9, page 10, FIG. 3)

しかしながら、特許文献1に記載の一時的な犯人拘束装置は、拘束網を展開して侵入者を捕捉する装置おいて、センサーによる作動方法について開示するに過ぎず、その拘束網を展開させる装置自体について具体的な構成の記載がなされていない。
また、侵入者を捕捉する手段において、侵入者の動作と拘束網の展開動作との関係が明らかでなく、また、放出する拘束網と錘との関係についても明らかでない。
However, the temporary criminal restraint device described in Patent Document 1 merely discloses an operation method by a sensor in a device that unfolds a restraint net and captures an intruder, and the device itself that deploys the restraint net itself. No specific configuration is described for.
Further, in the means for capturing the intruder, the relationship between the intruder's operation and the deployment operation of the restraint net is not clear, and the relationship between the releasing restraint net and the weight is not clear.

本発明者は、侵入者が保護物体へ近接した際、例えば、高さ3m程の天井に設置する拘束網展開装置を作動させて侵入者を捕捉しようとしたとき、捕捉前に侵入者がその足で拘束網のエリア範囲から逃避することを予測し、侵入者の足による移動時間を調べ侵入者を確実に捕捉することについて鋭意研究した。その結果、主として屋内に有効な拘束網の展開装置および方法を見出した。   When the intruder approaches the protective object, for example, when the intruder tries to capture the intruder by operating a restraint net deployment device installed on a ceiling of about 3 m in height, the intruder He predicted that he would escape from the area of the restraint net with his feet, and studied earnestly to detect the intruder by examining the time taken by the intruder's feet. As a result, an apparatus and method for deploying a restraint net that is effective mainly indoors have been found.

本発明は斯かる知見に基づいて為されたものであり、その目的は、拘束網を展開して侵入者を確実に捕捉することができる拘束網展開装置およびこれを用いた方法を提供することにある。   The present invention has been made based on such knowledge, and an object of the present invention is to provide a restraint network deployment device that can deploy an restraint network and reliably capture an intruder, and a method using the same. It is in.

ここで、本発明の原理を図30に基づいて説明する。
一般に、大人(男性、身長1.7m〜1.8m)の人間の歩行速度は約4Km/hである。すると、1秒当たりの移動距離は約1.1mとなるが、捕捉する確実性を考え、1.2mとする。
次に、1秒当たりの移動距離から、拘束網の径は中心部から半径1.2m(展開径2.4m)とするが、これでは余裕が無く逃げられる可能性があるので、余裕をみて拘束網の中心部から半径1.5m(展開径3m)とする。
Here, the principle of the present invention will be described with reference to FIG.
Generally, the walking speed of an adult (male, height 1.7 m to 1.8 m) is about 4 Km / h. Then, although the moving distance per second is about 1.1 m, it is set to 1.2 m in consideration of the certainty of capturing.
Next, from the moving distance per second, the diameter of the constraining net is 1.2 m (deployed diameter 2.4 m) from the center, but there is a possibility of escaping without a margin. The radius is 1.5 m (deployed diameter 3 m) from the center of the restraint net.

拘束網の中心部からの半径1.2m(展開径2.4m)は、展開径3mの80%展開に相当し捕捉可能であるが、さらなる確実性を求め、それよりも大きい90%展開(展開径2.7m)を設定する。
ここで、例えば、侵入者が拘束網展開装置の真下に存在するとした場合、1秒当たりの移動距離から、拘束網展開装置の作動後、侵入者は約1.2秒で拘束網の展開径から外れることとなるので、1.1秒以内であれば捕捉することができる。そこで、この1.1秒よりもさらに確実性をみて1秒を侵入者の捕捉時間として設定した。
A radius of 1.2 m (deployed diameter of 2.4 m) from the center of the restraint net corresponds to 80% deployment of the deployed diameter of 3 m and can be captured. Set the developed diameter 2.7m).
Here, for example, if the intruder is present directly under the restraint network deployment device, the intruder can deploy the restraint network in about 1.2 seconds from the moving distance per second after the operation of the restraint network deployment device. Therefore, it can be captured within 1.1 seconds. Therefore, 1 second was set as an intruder capture time with a certainty beyond 1.1 seconds.

拘束網展開装置の作動から侵入者を捕捉するまでの時間(X)≦1秒とする。
次に、拘束網展開装置の作動後、どの時点で拘束網がどの程度展開し着地すれば確実に侵入者を捕捉することができるかを想定した。
そこで、高さ3mの空間内に侵入した身長1.7m〜1.8mの侵入者を、全展張径3m(ここでは、3m×3mの八角形)の拘束網で展開させ捕捉するまでの時間を調べた。
Time (X) ≦ 1 second until the intruder is captured after the operation of the restraint net deploying device.
Next, after the operation of the restraint net deployment device, it was assumed at what point in time and how much the restraint net developed and landed so that an intruder could be reliably captured.
Therefore, the time required for an intruder who has entered a space of 3 m in height to be 1.7 m to 1.8 m tall to be deployed and captured by a restraint net with a total stretch diameter of 3 m (here, a 3 m × 3 m octagon). I investigated.

例えば、天井に設置した拘束網展開装置を作動させて、侵入者の顔面に網と連結する錘が直撃しない高さを約2mと設定し、その位置で拘束網を展開する動作を(1)とし、展開後、網と錘が2mの位置から自由落下して床面に着地する動作を(2)とする。
この2つの動作から、侵入者を捕捉するまでの時間(X)=動作(1)+動作(2)となる。
For example, by operating a restraint net deployment device installed on the ceiling and setting the height at which the weight connected to the net does not hit the intruder's face to about 2 m, and deploying the restraint net at that position (1) And (2) is an operation in which the net and the weight drop freely from the position of 2 m after landing and land on the floor surface.
From these two operations, the time until the intruder is captured (X) = operation (1) + operation (2).

ここで、自由落下「動作(2)」は、下式が成り立つ。
y=1/2gt2・・・(Y)
y:落下高さ(m)、g:重力加速度=9.8(m/s2)、t:時間(s)
ここでは、落下高さを2mとしているので、式(Y)を当てはめると、
2=1/2×9.8×t2
t=0.638
となり、動作(2)は約0.6秒となる。
Here, for the free fall “motion (2)”, the following equation is established.
y = 1 / 2gt 2 (Y)
y: fall height (m), g: gravitational acceleration = 9.8 (m / s 2 ), t: time (s)
Here, the drop height is 2 m, so if the equation (Y) is applied,
2 = 1/2 × 9.8 × t 2
t = 0.638
Thus, operation (2) takes about 0.6 seconds.

そして、拘束網展開装置の作動から侵入者を捕捉するまでの時間(X)を約1秒としているので、動作(1)は約0.4秒となる。
これらにより、落下高さ約2mの位置で0.4秒以内に拘束網を90%以上展開させれば確実に侵入者を捕捉できることとなる。
ここで、0.4秒以内で拘束網を90%以上展開させるには、所定展開径の網を引っ張り出し展開させる錘の速度が必要となる。また、網の重量と錘の重量との重量比の関係も有る。また、錘を噴出する噴出口の角度の関係もある。
Then, since the time (X) from the operation of the restraint network deploying device until the intruder is captured is about 1 second, the operation (1) is about 0.4 seconds.
As a result, an intruder can be reliably captured if the restraint net is deployed 90% or more within 0.4 seconds at a position where the drop height is about 2 m.
Here, in order to deploy 90% or more of the restraint net within 0.4 seconds, the speed of the weight for pulling out and deploying the net with a predetermined development diameter is required. There is also a weight ratio relationship between the weight of the net and the weight of the weight. In addition, there is a relationship of the angle of the ejection port that ejects the weight.

これらの関係は、拘束網展開装置の設置条件でも変化するものであり、上記諸関係の組合せにより本発明の目的を多様に達成できる。

The cooled and filtered gas flows from the eight gas flow paths 25 to the jet outlet 25a.
As shown in FIGS. 13 to 15, the weight 16 includes a weight body 17 and a weight case 18.

各錘16が噴出口25aから脱落するのを防止するためには、例えば、下記の2案がある。(1)噴出口25aに所定の粘着性を有する粘着性物質を配設すること、例えば、錘16が円柱体で噴出口25aの内壁としっくり収まる程度の外径を形成する。そして、噴出口25aから錘収容部26へ収納した後、噴出口25aの外側を、所定圧力で剥離する比較的薄い粘着テープで塞ぐことである。また、(2)錘16の最大外形部と噴出口25aの内壁部とに所定の摩擦を有するように形成することである。本実施形態では、(2)案を用いた。   In order to prevent each weight 16 from falling off the jet nozzle 25a, for example, there are the following two plans. (1) Arranging an adhesive substance having a predetermined adhesiveness at the ejection port 25a, for example, forming an outer diameter that allows the weight 16 to be a cylindrical body that fits snugly as the inner wall of the ejection port 25a. And after accommodating from the jet nozzle 25a to the weight accommodating part 26, it is closing the outer side of the jet nozzle 25a with the comparatively thin adhesive tape which peels with predetermined pressure. Moreover, (2) It is forming so that it may have predetermined | prescribed friction in the largest external shape part of the weight 16, and the inner wall part of the jet nozzle 25a. In this embodiment, the plan (2) is used.

錘本体17は、ここでは所定の重量を有する金属製の円柱体から成り、一側端所定位置に紐部材37と連結する穴17aが設けてある。
また、錘ケース18は、ここでは一側と他側で分割される樹脂製の中空筒状体から成り、分割部分の各開口部19e,20aから錘本体17を挿入することができ、また、それぞれにねじ部19c,20bが形成され螺合できる形態としている。
The weight main body 17 is here made of a metal cylinder having a predetermined weight, and is provided with a hole 17a connected to the string member 37 at a predetermined position on one side end.
In addition, the weight case 18 is formed of a resin hollow cylindrical body that is divided on one side and the other side, and the weight body 17 can be inserted from each opening 19e, 20a of the divided portion. Threaded portions 19c and 20b are formed on each of them, and can be screwed together.

一側の中空筒状体19は、図13,図14に示すように、底面が閉塞される底部19aと、錘本体17の略半分がしっくり収まる空間部19bと、内部に形成され他側中空筒状体20のねじ部20bと螺合するねじ部19cとを有し、底部19aの外形がクレーター状(オブチレーター状)に形成されている。さらに、この底部19aの端部外周に僅かな鍔部19dが形成されている。   As shown in FIGS. 13 and 14, the hollow cylindrical body 19 on one side includes a bottom portion 19 a whose bottom surface is closed, a space portion 19 b in which substantially half of the weight body 17 fits, and a hollow on the other side. It has a screw part 19c that is screwed with the screw part 20b of the cylindrical body 20, and the outer shape of the bottom part 19a is formed in a crater shape (obtilator shape). Further, a slight flange portion 19d is formed on the outer periphery of the end portion of the bottom portion 19a.

他側の中空筒状体20は、図13,図15に示すように、開口部20a側の外周に形成され一側の中空筒状体19のねじ部19cと螺合するねじ部20bと、錘本体17の略半分がしっくり収まる空間部20cと、ねじ部20bの反対側端部に形成され錘本体17からの紐部材37を通すための貫通孔20eを備えた底部20dとを有する。
これにより、錘16自体を、一側の中空筒状体19の開口部19eから嵌入し空間部19bに収める。さらに、錘16自体の一側に付けられた紐部材を、他側の中空筒状体20の貫通孔20eから外へ引き出し、この空間部20cへ嵌入し収める。
As shown in FIGS. 13 and 15, the other-side hollow cylindrical body 20 is formed on the outer periphery on the opening 20 a side and is screwed with a threaded portion 19 b of the one-side hollow cylindrical body 19. It has a space portion 20c in which substantially half of the weight body 17 fits properly, and a bottom portion 20d provided with a through hole 20e that is formed at the opposite end of the screw portion 20b and allows the string member 37 from the weight body 17 to pass therethrough.
Accordingly, the weight 16 itself is fitted from the opening 19e of the hollow cylindrical body 19 on one side and is stored in the space 19b. Further, the string member attached to one side of the weight 16 itself is pulled out from the through hole 20e of the hollow cylindrical body 20 on the other side, and is fitted into the space portion 20c.

そして、一側の中空筒状体19の開口部19eが他側の中空筒状体20の段部20fに当接するまで、それぞれの開口部19e,20aに形成したねじ部19c,20bを螺合し錘ケース18として一体的にする。
また、鍔部19dは、錘16を収容する噴出口25aの内径と所定の摩擦係数を有することとなるので、噴出口25a内で保持されことになる。さらに、鍔部19dのクレーター状を有する外側底部19aは圧力ガスを充分に受けやすくなる。
Then, until the opening portion 19e of the hollow cylindrical body 19 on one side contacts the stepped portion 20f of the hollow cylindrical body 20 on the other side, the screw portions 19c and 20b formed in the respective opening portions 19e and 20a are screwed together. The weight case 18 is integrated.
Further, since the flange portion 19d has a predetermined friction coefficient with the inner diameter of the ejection port 25a that accommodates the weight 16, it is held in the ejection port 25a. Further, the outer bottom portion 19a having a crater shape of the flange portion 19d is sufficiently susceptible to pressure gas.

錘容器21は、図5ないし図8に示すように、ここでは略漏斗形状を為すアルミニウム製部材から成り、ガス発生装置10とフイルター15を収容する空間部22aを形成するとともに拘束網展開装置Aを建物に設置するためのねじ部22cを外周に形成した円筒部22と、この円筒部22の付け根22bから円形に拡張して形成された円板状の傾斜面23と、この傾斜面23の外縁部23aから垂直に形成された円筒状の外周壁24と、内部に円筒部22の空間部22aと連通し八方向に分岐するとともに外周壁24の外側に開通する八つのガス流路25と、八つのガス流路25の噴出口25a側の所定位置に形成した錘収容部26と、傾斜面23と対向する裏面側に位置し、網容器30と嵌合するためのねじ部28aを内周面に備えた凹部28を有する底面27とを有する。   As shown in FIGS. 5 to 8, the weight container 21 is made of an aluminum member having a substantially funnel shape, and forms a space portion 22 a that houses the gas generator 10 and the filter 15, and a restraint net deploying device A.

Concave on the circumference And a bottom surface 27 having a 28.

拘束網29は、図12に示すように、ここではポリエステル製またはケブラー製で3m×3mの八角形に構成されている。また、目幅(1つの目幅)は、全展開面積(3m×3m)の約半分を中心部29a付近から20cm角(内側網目29b)で形成し、残り約半分を10cm角(外側網目29c)で形成するようにしても良い。また、この目幅については、全展開面積で中心部29aから、内側網目29bと外側網目29cとを均等に形成することでも良い。   As shown in FIG. 12, the restraint net 29 is made of polyester or Kevlar and has an octagon shape of 3 m × 3 m. As for the mesh width (one mesh width), about half of the total development area (3 m × 3 m) is formed by 20 cm square (inner mesh 29b) from the vicinity of the central portion 29a, and the remaining half is 10 cm square (outer mesh 29c). ). As for the mesh width, the inner mesh 29b and the outer mesh 29c may be evenly formed from the central portion 29a over the entire developed area.

紐部材37は、ここではポリエステル製で径0.7mmの紐を用いており、一側が錘本体17と連結するとともに他側が拘束網29と連結している。そして、この紐部材37は、錘容器21から錘16が飛び出すとともに網容器30から拘束網29を展開するときの力にも耐える材質としている。
網容器30は、図9ないし図11に示すように、ここでは略コップ形状を為すアルミニウム製部材から成り、錘容器29の凹部28の内周面に形成したねじ部28aと螺合するねじ部31aを外周に形成した凸形状の円柱部31と、円柱部31の付け根31bから少し延伸したところから円形に拡張して形成されるとともに壁面の所定箇所に複数の小孔32bを形成した円板状の傾斜面32と、傾斜面32の外縁部32aから垂直に形成されるとともに周囲に等間隔で八カ所の縦溝33aを形成した円筒状の外周壁33と、外周壁33の端部を断面L字形に折り曲げて形成した蓋止部34と、傾斜面32と外周壁33との間に形成された拘束網29を収容する空間部35とを有する。複数の小孔32bは、紐部材37により錘16と連結する拘束網29を吸引して収容するために設けてある。
Here, the string member 37 is made of polyester and has a diameter of 0.7 mm, and one side is connected to the weight body 17 and the other side is connected to the restraint net 29. The string member 37 is made of a material that can withstand the force when the weight 16 protrudes from the weight container 21 and the restraint net 29 is expanded from the net container 30.
As shown in FIGS. 9 to 11, the net container 30 is made of an aluminum member having a substantially cup shape, and is a screw part that is screwed with a screw part 28 a formed on the inner peripheral surface of the concave part 28 of the weight container 29. A circular cylinder 31 having a convex shape 31a formed on the outer periphery, and a disk formed by extending a little from a base 31b of the cylindrical part 31 into a circular shape and having a plurality of small holes 32b at predetermined locations on the wall surface A cylindrical inclined surface 32, a cylindrical outer peripheral wall 33 formed vertically from the outer edge portion 32a of the inclined surface 32 and having eight vertical grooves 33a formed at equal intervals around the periphery, and an end portion of the outer peripheral wall 33 It has a lid stopper 34 that is formed by bending it into an L-shaped cross section, and a space 35 that accommodates a restraining net 29 formed between the inclined surface 32 and the outer peripheral wall 33. The plurality of small holes 32 b are provided for sucking and housing the restraint net 29 connected to the weight 16 by the string member 37.

ここで、拘束網29の網容器30への収容と、網容器30への錘16の収納について説明する。
先ず、網容器30の円柱部31側から傾斜面32上に形成される***32b全部を覆うようにして、図示しないアタッチメントを用いて吸引装置(例えば、ブレスガン)に繋ぐ。そして、展開された拘束網29に取り付けた全ての錘16を纏め、錘16を上にして錘16と拘束網29が絡まらないようにして拘束網29を網容器30の中心部へ垂らし、吸引を開始し、錘16を除く全ての拘束網29を収納する。その後、吸引装置を外す。
Here, accommodation of the restraining net 29 in the net container 30 and accommodation of the weight 16 in the net container 30 will be described.
First, the small holes 32b formed on the inclined surface 32 are covered from the cylindrical portion 31 side of the mesh container 30 and connected to a suction device (for example, a breath gun) using an attachment (not shown). Then, all the weights 16 attached to the deployed restraint net 29 are gathered, the restraint net 29 is hung to the center of the net container 30 so that the weight 16 and the restraint net 29 are not entangled with the weight 16 facing upward, and suction is performed. And all the restraint nets 29 except the weight 16 are accommodated. Thereafter, the suction device is removed.

そして、この拘束網29を収容した網容器30と錘容器21とをねじ部31a,28aを介して接続する。
次に、錘16を錘容器21の噴出口25aへ鍔部19d側から嵌入する。
その後、例えば、ゴム製で厚さ2mmの円盤状に形成されている蓋部材38を、網容器30の蓋止部34の内側へ嵌め込み開口部36を塞ぎ保持する。
And the net container 30 which accommodates this restraining net | network 29 and the weight container 21 are connected via the screw parts 31a and 28a.
Next, the weight 16 is fitted into the spout 25a of the weight container 21 from the flange portion 19d side.
Thereafter, for example, a lid member 38 made of rubber and formed in a disk shape having a thickness of 2 mm is fitted inside the lid stopper 34 of the mesh container 30 to close and hold the opening 36.

このとき、紐部材37は網容器30の外周壁33の縦溝33aに沿って外側に垂れ下がる形となる。
以上により、図1ないし図4に示す状態となる。
次に、本実施形態に係る拘束網展開装置Aの作用について述べる。
本実施形態に係る拘束網展開装置Aは、図16に示すように、例えば、錘容器21の円筒部22の外周に形成したねじ部22cを、天井板39に設けた開口部(図示せず)に螺着することによって錘容器21および網容器30を天井板39から室内に向かって垂下する形で取り付けられる。
At this time, the string member 37 hangs outward along the longitudinal groove 33 a of the outer peripheral wall 33 of the net container 30.
As a result, the state shown in FIGS. 1 to 4 is obtained.
Next, the operation of the restricted net deployment device A according to this embodiment will be described.
As shown in FIG. 16, the restraint net deploying apparatus A according to the present embodiment has, for example, an opening (not shown) provided with a screw portion 22 c formed on the outer periphery of the cylindrical portion 22 of the weight container 21 in the ceiling plate 39. The weight container 21 and the net container 30 are attached so as to hang down from the ceiling plate 39 toward the room.

センサーが、例えば屋内への侵入者を検知すると、センサーから拘束網展開装置Aを作動させるための電気的信号が発せられ、その電気的信号で点火器11内の発熱体に配設された着火薬が燃焼するとともにガス発生剤11eへ伝火・燃焼し高圧ガスを生成する。この燃焼ガスは、フイルター15で濾過され圧力ガスとなって八経路のガス流路25へ均等に流入し、噴出口25aに配置された錘16に推力を与える。   When the sensor detects an intruder, for example, indoors, an electrical signal for operating the restraint net deployment device A is emitted from the sensor, and the electrical signal that is placed on the heating element in the igniter 11 is generated by the electrical signal. The explosive is combusted and transferred to the gas generating agent 11e and burned to generate high-pressure gas. This combustion gas is filtered by the filter 15 to become pressure gas, and flows equally into the eight gas flow paths 25, and gives a thrust to the weight 16 disposed at the jet outlet 25a.

そして、この推力により8個の錘16が角度を有する8カ所の噴出口25aから均等に所定の速度で噴出する。
これにより、噴出した8個の錘16と紐部材37で連結している拘束網29が網容器30の蓋部材38を弾いて外へ引き出される。さらに、8個の錘16は推力を維持しながら拘束網29を装置外へ引き出し展開させる。
The eight weights 16 are ejected from the eight jet outlets 25a having an angle evenly at a predetermined speed by this thrust.
As a result, the restraint net 29 connected to the eight ejected weights 16 and the string member 37 repels the lid member 38 of the net container 30 and is pulled out. Further, the eight weights 16 pull out and deploy the restraint net 29 outside the apparatus while maintaining the thrust.

斯くして展開された拘束網29は、侵入者を捕捉し犯罪行為を未然に防止することができる。
(実験例1)
本実施形態に係る拘束網展開装置Aを用いて、錘16の展開角度(打ち出し角度)20度、拘束網29と錘16との重量比を1:2.9とし、拘束網29の目幅を11cmに固定し、拘束網29を展開した実験例を示す。
The restraint network 29 deployed in this manner can capture intruders and prevent criminal acts.
(Experimental example 1)
Using the restraint net deployment device A according to the present embodiment, the deployment angle (launch angle) of the weight 16 is 20 degrees, the weight ratio of the restraint net 29 and the weight 16 is 1: 2.9, and the mesh width of the restraint net 29 is An experimental example is shown in which is fixed to 11 cm and the restraint net 29 is developed.

先ず、本実施形態に係る拘束網展開装置Aを天井に水平に設置して5回実施した。さらに、本実施形態に係る拘束網展開装置Aを側壁に垂直に対して斜め45度に設置して1回実施した。さらに、真横90度に設置して1回実施した。
その結果を表1に示す。
ここでは、(1)水平に設置した場合、例えば、最大圧力Pmaxにおいて1.54〜5.54の範囲でバラツキが生じたが、これは、錘16の最大外径部と噴出口25aの内壁部とに所定の摩擦係数が生じているためである。しかしながら、0.2秒未満に90%以上展開し、展開位置も2mを超えていることから問題ないものと考えられる。
First, the restraint net deployment device A according to the present embodiment was installed horizontally on the ceiling and carried out five times. Further, the restraint net deployment device A according to the present embodiment was installed once at an angle of 45 degrees with respect to the vertical to the side wall. Furthermore, it was installed once at a right angle of 90 degrees.
The results are shown in Table 1.
Here, (1) when installed horizontally, for example, variation occurred in the range of 1.54 to 5.54 at the maximum pressure Pmax. This is due to the maximum outer diameter portion of the weight 16 and the inner wall of the jet outlet 25a. This is because a predetermined coefficient of friction is generated in each part. However, it is considered that there is no problem because 90% or more is developed in less than 0.2 seconds and the development position is over 2 m.

また、(2)斜め45度に設置した場合においても、0.2秒未満に90%以上展開し、展開位置も2mを超えている。
また、(3)90度に設置した場合においても、0.23秒に90%以上展開し、展開位置も2mを超えている。
Further, (2) even when installed at an angle of 45 degrees, 90% or more is deployed in less than 0.2 seconds, and the deployment position is over 2 m.
(3) Even when installed at 90 degrees, 90% or more is deployed in 0.23 seconds, and the deployment position is over 2 m.

本実施形態に係る拘束網展開装置Bは、ガス発生装置10に変えてエア圧力タンク50を用いた点で、第一実施形態に係る拘束網展開装置Aとは相違する。従って、以下の説明では、第一実施形態に係る拘束網展開装置Aと同一部材については同一の符号を付し、その説明を省略する。
(Second embodiment)
FIG. 17 is a schematic external view of a restraint net deployment device B according to the second embodiment of the present invention, and FIG. 18 is a sectional view thereof.
The restraint net deployment device B according to the present embodiment is different from the restraint mesh deployment device A according to the first embodiment in that an air pressure tank 50 is used instead of the gas generator 10. Therefore, in the following description, the same code | symbol is attached | subjected about the same member as the restraint net | network expansion | deployment apparatus A which concerns on 1st embodiment, and the description is abbreviate | omitted.

本実施形態に係る拘束網展開装置Bは、図示しないエア圧力発生機からのエアをエアホース51で導入し貯蔵するエア圧力タンク50と、このエア圧力タンク50と螺着・連通するガス流路管52と、このガス流路管52と中間取付部53を介して導通する電磁弁付開閉装置54と、この電磁弁付開閉装置54と中間取付部55を介して導通する錘容器21Aと、この錘容器21A内の8つに区画された錘収容部26に収納される8つの錘16と、網容器30内に収納される8角形の拘束網29と、これら拘束網29と錘16とを連結する紐部材37と、網容器30を塞ぐ蓋部材38とで構成されている。   The restraint net developing device B according to the present embodiment includes an air pressure tank 50 that introduces and stores air from an air pressure generator (not shown) through an air hose 51, and a gas flow channel pipe that is screwed and communicated with the air pressure tank 50. 52, an opening / closing device 54 with an electromagnetic valve that is electrically connected via the gas flow pipe 52 and the intermediate mounting portion 53, a weight container 21A that is electrically connected via the opening / closing device 54 with an electromagnetic valve and the intermediate mounting portion 55, and The eight weights 16 accommodated in the weight accommodating part 26 divided into eight in the weight container 21A, the octagonal restraint net 29 accommodated in the net container 30, and the restraint net 29 and the weight 16 A string member 37 to be connected and a lid member 38 for closing the net container 30 are configured.

ここで、錘容器21Aは、円筒部22にフィルタ15を設けない点で異なる。
エア圧力タンク50は、エア充填室を有し、一側の開口部にねじ部が形成されガス流路管52と螺合している。このエア充填室には、例えば、充填圧を500KPaの範囲で充填することができる。
電磁弁付開閉装置54は、エア圧力タンク50のガス流路管52と錘容器21Aとの間に配設し、両端にねじ部が形成されている。これら両ねじ部は、エア圧力タンク50のガス流路管52のねじ部と接続され、かつ錘容器21Aの一側端のねじ部22eと接続され、それぞれで連通する。また、この電磁弁付開閉装置54は、スイッチ部54aにより開成−閉成が可能となっている。
Here, the weight container 21 </ b> A is different in that the filter 15 is not provided in the cylindrical portion 22.
The air pressure tank 50 has an air filling chamber, and a threaded portion is formed in an opening on one side and is screwed into the gas flow path pipe 52. For example, the air filling chamber can be filled with a filling pressure in the range of 500 KPa.
The electromagnetic valve-equipped opening / closing device 54 is disposed between the gas flow path pipe 52 of the air pressure tank 50 and the weight container 21A, and has threaded portions at both ends. These two screw portions are connected to the screw portion of the gas flow path pipe 52 of the air pressure tank 50 and are connected to the screw portion 22e at one end of the weight container 21A, and communicate with each other. Further, the opening / closing device 54 with a solenoid valve can be opened and closed by a switch portion 54a.

次に、斯くして構成された本実施形態に係る拘束網展開装置Bの作用を説明する。
本実施形態においても、第一実施形態に係る拘束網展開装置Aと同様に、センサーが、例えば屋内への侵入者を検知すると、センサーの電気的信号が発せられ、その電気的信号でスイッチ部54aが開成され、圧力タンク50内の高圧ガスが八経路のガス流路25へ均等に流入し、噴出口25aに配置された錘16に推力を与える。
Next, the operation of the restricted net deployment device B according to the present embodiment configured as described above will be described.
Also in this embodiment, as in the restraint network deployment device A according to the first embodiment, when the sensor detects an intruder, for example, indoors, an electrical signal of the sensor is emitted, and the switch portion is generated by the electrical signal. 54a is opened, and the high-pressure gas in the pressure tank 50 flows evenly into the eight gas flow paths 25, and gives thrust to the weight 16 disposed at the jet outlet 25a.

そして、この推力により8個の錘16が角度を有する8カ所の噴出口25aから均等に所定の速度で噴出する。
これにより、噴出した8個の錘16と紐部材37で連結している拘束網29が網容器30の蓋部材38を弾いて外へ引き出される。さらに、8個の錘16は推力を維持しながら拘束網29を装置外へ引き出し展開させる。
The eight weights 16 are ejected from the eight jet outlets 25a having an angle evenly at a predetermined speed by this thrust.
As a result, the restraint net 29 connected to the eight ejected weights 16 and the string member 37 repels the lid member 38 of the net container 30 and is pulled out. Further, the eight weights 16 pull out and deploy the restraint net 29 outside the apparatus while maintaining the thrust.

斯くして展開された拘束網29は、侵入者を捕捉し犯罪行為を未然に防止することができる。
次に、本実施形態に係る拘束網展開装置Bの拘束網展開方法について、基礎実験装置(以下、実験装置と呼ぶ。)を用いて実験・解析したことを詳細に述べる。
図19は、実験装置の外観概要図を示す。
The restraint network 29 deployed in this manner can capture intruders and prevent criminal acts.
Next, it will be described in detail that the restraint network deployment method of the restraint network deployment apparatus B according to the present embodiment has been tested and analyzed using a basic experiment apparatus (hereinafter referred to as an experiment apparatus).
FIG. 19 shows a schematic external view of the experimental apparatus.

ここでは、網容器30を用いず、拘束網29を自重で垂れ下げた状態にしてある。また、噴出部25aは、錘16の装填後に、噴出部25aの外側から薄い粘着テープなどで塞がれている。錘16は、鉄製であり危険防止のため、錘全体にゴムカバーを施してある。
次に、実験装置の作用を説明する。
エア圧力タンク50へ所定量のエアを充填する。充填後、電磁弁付開閉装置54のスイッチ部54aを作動させて圧力エアを錘容器21内の8箇所の錘収容部26へ均等に解放・流入させる。
Here, the mesh container 30 is not used, and the restraint net 29 is suspended by its own weight. In addition, after the weight 16 is loaded, the ejection portion 25a is closed with a thin adhesive tape or the like from the outside of the ejection portion 25a. The weight 16 is made of iron, and a rubber cover is applied to the entire weight to prevent danger.
Next, the operation of the experimental apparatus will be described.
The air pressure tank 50 is filled with a predetermined amount of air. After filling, the switch portion 54a of the electromagnetic valve opening / closing device 54 is operated to release and flow the pressure air evenly into the eight weight housing portions 26 in the weight container 21.

この圧力エアの流入により、8個の錘16が各噴出部25aから均等に飛翔し、それに引っ張られて拘束網29が展開する。
次に、図20に示すように、実験装置による実験の測定方法を説明する。
5m四方で高さ3m強の骨組だけの実験室を用意し、この実験室の天井中央部の支柱に実験装置を配置し、地上から実験装置までの高さを約3mとした。
Due to the inflow of the pressure air, the eight weights 16 fly evenly from the respective ejection portions 25a, and are pulled thereby to expand the restraint net 29.
Next, as shown in FIG. 20, a measurement method of an experiment using an experimental apparatus will be described.

FIG. 29 is a graph showing the relationship between the weight ratio of the restraint net (Net) and the weight and the 90% development time.
Here, it can be seen that if the restraint net and weight are about 1: 3 or more, the 90% expansion time is approximately constant between 0.3 seconds and 0.4 seconds.

(実験例2〜7)
実験例2〜実験例4は、図19に示す実験装置により行い、実験例5と実験例6は、第二実施形態に係る拘束網展開装置Bにより行った。
測定方法は、前述した図20により行い、また、圧力に関しては図17に示すように、中間取付部55に隣接する錘容部21Aの円筒部22に設置して行った。
(Experimental Examples 2-7)
Experimental Example 2 to Experimental Example 4 were performed by the experimental device shown in FIG. 19, and Experimental Example 5 and Experimental Example 6 were performed by the restraint network deployment device B according to the second embodiment.
The measurement method was performed according to FIG. 20 described above, and the pressure was set on the cylindrical portion 22 of the weight portion 21A adjacent to the intermediate mounting portion 55 as shown in FIG.

(実験例2)表2上段参照
実験装置を用いて、錘の展開角度(打ち出し角度)を水平(0度)にし、網1に対して錘を1.8、1.2および1.24の3水準の重量比とし、各重量比において120KPaと180KPaのエア充填圧をもって、それぞれ3回つ実施した。
ここでは、エア充填圧が120KPaのとき、90%展開時間が0.4〜0.5秒で、網と錘の重量比が小さいほど秒数が掛かることが分かる。また、180KPaでは120KPaより速い90%展開時間となり、さらに網と錘の重量比が大きくなるほど120KPaのときより90%展開時間の開きが大きくなることが分かる。
(Experimental example 2) Refer to the upper part of Table 2. Using the experimental apparatus, the weight deployment angle (launch angle) was set to horizontal (0 degree), and the weight was 1.8, 1.2 and 1.24 with respect to the net 1. 3 and level weight ratio, with the air filling pressure of 120KPa and 180KPa in each weight ratio were carried One not a 3 times each.
Here, it can be seen that when the air filling pressure is 120 KPa, the 90% expansion time is 0.4 to 0.5 seconds, and the smaller the weight ratio between the net and the weight, the longer the number of seconds. It can also be seen that at 180 KPa, the 90% development time is faster than 120 KPa, and that the 90% development time gap increases as the weight ratio between the net and the weight increases, compared to 120 KPa.

また、90%展開位置が全体にわたって高い位置(1.7m〜2.3m)であった。
(実験例3)表2下段参照
実験装置を用いて、錘の展開角度(打ち出し角度)を30度にし、網1に対して錘を2.0、2.4、3.0、3.9および5.4の5水準の重量比とし、重量比1:2.4については120KPaと180KPaのエア充填圧をもって、その他は180KPaの充填圧をもって、それぞれ3回ずつ実施した。
In addition, the 90% developed position was a high position (1.7 m to 2.3 m) throughout.
(Experimental example 3) Refer to the lower part of Table 2. Using an experimental device, the weight deployment angle (launch angle) is set to 30 degrees, and the weight is set to 2.0, 2.4, 3.0, 3.9 with respect to the net 1. And a weight ratio of 5 levels of 5.4 and 5.4, with a weight ratio of 1: 2.4, air filling pressures of 120 KPa and 180 KPa, and the others were carried out three times each with a filling pressure of 180 KPa.

ここでは、エア充填圧120KPaにおいて、90%展開時間が0.5〜0.53秒であり展開位置も1mを切っている。これは実験例2における120KPaよりも良くない結果となっている。しかしながら、エア充填圧180KPaで、網と錘の重量比で錘のウェートが高くなるほど90%展開時間および展開位置が良い結果が出ており、重量比1:5.4では90%展開時間0.3秒の展開位置1.7mである。   Here, at an air filling pressure of 120 KPa, the 90% deployment time is 0.5 to 0.53 seconds and the deployment position is less than 1 m. This is a result that is not better than 120 KPa in Experimental Example 2. However, at an air filling pressure of 180 KPa, the higher the weight weight of the net and the weight, the better the 90% deployment time and deployment position. At a weight ratio of 1: 5.4, the 90% deployment time is 0. The unfolded position for 3 seconds is 1.7 m.

(実験例4)表3参照
実験装置を用いて、錘の展開角度(打ち出し角度)を20度と30度にし、網1に対して錘を2.5の重量比に固定して、350KPa、400KPa、450KPa、500KPaのエア充填圧をもって、それぞれ3回つ実施した。
ここでは、エア充填圧が高くなるにつれVmax、Pmax、E(J)が大きくなり、90%展開時間が速くなるとともに展開位置が高くなる。
(Experimental example 4) See Table 3. Using an experimental apparatus, the weight deployment angle (launch angle) was set to 20 degrees and 30 degrees, the weight was fixed to the net 1 at a weight ratio of 2.5, and 350 KPa, 400 kPa, 450 kPa, with an air filling pressure of 500 KPa, was carried One not a 3 times each.
Here, as the air filling pressure increases, Vmax, Pmax, and E (J) increase, and the deployment position increases as the 90% deployment time increases.

また、錘の展開角度の20度と30度では、30度の方がVmax、Pmax、E(J)において大きい数値であり、90%展開時間も速くなっているが展開位置においては小さい値となっている。
(実験例5)表4参照
拘束網展開装置Bを用いて、網1に対して錘2.5の重量比と500KPaのエア充填圧に固定して、錘の展開角度(打ち出し角度)20度と30度をもって、それぞれ3回つ実施した。
In addition, when the extension angles of the weights are 20 degrees and 30 degrees, 30 degrees is a larger value in Vmax, Pmax, and E (J), and the 90% deployment time is faster, but a smaller value is obtained at the deployment position. It has become.
(Experimental example 5) See Table 4 Using the restraint net deployment device B, the mass 1 is fixed to the weight ratio of the weight 2.5 and the air filling pressure of 500 KPa, and the mass deployment angle (launch angle) is 20 degrees. with the 30 degrees was performed One not a 3 times each.

ここでは、実験例4と同ように錘の展開角度の20度と30度では、30度の方がVmax、Pmax、E(J)において大きい数値であり、90%展開時間も速くなっているが展開位置においては小さい値となっている。
また、本実験例の網を収納した拘束網展開装置Bと、実験例4の拘束網を未収納した実験装置での90%展開時間、展開位置、Vmax、Pmax、E(J)においては多少の差はあったが、特に0.4秒以内−90%展開に係る問題はないと考察できる。
Here, in the same way as in Experimental Example 4, with 20 and 30 degrees of the spread angle of the weight, 30 degrees is a larger value in Vmax, Pmax, and E (J), and the 90% spread time is also faster. Is a small value at the deployed position.
Further, the 90% deployment time, deployment position, Vmax, Pmax, and E (J) in the restraint net deployment apparatus B that accommodates the net of this experimental example and the experiment apparatus that does not accommodate the restraint net of Experimental Example 4 are somewhat different. However, it can be considered that there is no problem with -90% development within 0.4 seconds.

(実験例6)表5参照
拘束網展開装置Bを用いて、網1に対して錘2.5の重量比、500KPaのエア充填圧および錘の展開角度(打ち出し角度)20度に固定し、網の一つの目幅7.5cm、10cm、12.5cm、15cmおよび外側10cm−内側20cmをもって、それぞれ5回つ実施した。
(Experimental example 6) Refer to Table 5. Using the restraint net deployment device B, the weight ratio of the weight 2.5 to the net 1 is fixed to an air filling pressure of 500 KPa and a weight deployment angle (launch angle) of 20 degrees. network one eye width 7.5cm of, with 10 cm, 12.5 cm, 15cm and outer 10cm- inner 20 cm, was carried one not a 5 times, respectively.

ここでは、拘束網から人間がどの程度の時間で網から脱出できるかを、ストップウォッチで脱出時間を計測した。脱出時間の目標を仮に30秒以上とした。
網の目幅10cm、12.5cmおよび外側10cm−内側20cmのタイプでは30秒以上掛かったが、7.5cmと15cmでは30秒以上達成したものがなかった。
また、外側10cm−内側20cmのタイプでは、2倍の60秒近いものがあった。
Here, we measured the escape time with a stopwatch to determine how long a person can escape from the net. The escape time target was temporarily set to 30 seconds or more.
The mesh width of 10 cm, 12.5 cm, and outer 10 cm-inner 20 cm took 30 seconds or more, but 7.5 cm and 15 cm did not achieve 30 seconds or more.
Moreover, in the type of 10 cm outside-20 cm inside, there was a double of nearly 60 seconds.
