【従来の技術】[Prior art]

従来、一般的なこの種の信号発炎筒は、両端が閉塞された紙製の円筒体と、該 円筒体の内部に充填した発炎薬と、円筒体の一端にて、前記発炎薬に連繋すべく 埋設した伝火薬と、該伝火薬に連繋し、外部に露出させた発火薬と、該円筒体の 前記一端近傍の外周に被冠し得るよう成した、すり付け薬を外面に付設したキャ ップとから構成したものであった。なお、前記円筒体は、発炎薬の燃焼熱等の他 からの熱の供給で燃焼し、熱の供給が絶たれると消火し延焼しない性質、いわゆ る自己消火性を有する紙で構成されている。この発炎筒を使用する時は、先ず、 キャップを外し、キャップの前記すり付け薬で発火薬をすり着火する。発火した 火は、伝火薬に伝わり、さらに伝火薬から前記発炎薬に伝わるとともに、円筒体 の前記一端の紙が燃えて消滅しここが開口する。このようにして燃焼を始めた該 発炎薬は、遠方より容易に視認しうる炎と煙をあげながら徐々に円筒の他端に向 かって燃焼する。そして、例えば、工事実施場所近辺において道路管理者は、専 用車両から降りて、前述のように着火した複数の発炎筒を所定間隔をおいて路上 に立てるという配置作業を行うのである。 Conventionally, this type of general signal firing cylinder has a paper cylinder whose both ends are closed, a flame generator filled inside the cylinder, and one end of the cylinder connected to the flame medicine. In order to be able to be crowned on the outer periphery of the transfer charge that is buried in order to be connected to the transfer charge and exposed to the transfer charge, and the outer periphery of the cylindrical body in the vicinity of the one end, and attached to the outer surface It was made up of a cap. The cylinder is made of paper that burns when heat is supplied from other sources, such as the heat of combustion of the flame-retardant, and does not spread when the heat supply is cut off, that is, it has a so-called self-extinguishing property. ing. When using this flaming cylinder, first, the cap is removed, and the ignition powder is rubbed and ignited by the above-mentioned scouring agent on the cap. The ignited fire is transmitted to the transfer charge, and further from the transfer charge to the flammable charge. At the same time, the paper at the one end of the cylindrical body burns and disappears, and the opening is opened. The flaming agent that has started burning in this way gradually burns toward the other end of the cylinder, with a flame and smoke that are easily visible from a distance. Then, for example, in the vicinity of the construction site, the road administrator dismounts from the dedicated vehicle and sets up a plurality of ignited flaming cylinders on the road at predetermined intervals as described above.

【０００３】 また、高速道路において前述のような配置作業を行うことは、他の高速走行車 両のドライバーが作業者を遠方より視認しにくいため危険であるという点を考慮 して、例えば、実開昭５７−１３１７８５号公報あるいは実開昭５７−１３１７ ８６号公報に開示されたような、専用車両内から路上に投下して前記配置作業を 行い得る発炎筒が提案されている。これら発炎筒は、１個〜数個の転がり防止用 の突起を形成したリングあるいはパイプ体を、外周に嵌合し固着するという転が り防止策を施したものである。Considering that it is dangerous to perform the above-described arrangement work on a highway because it is difficult for drivers of other high-speed vehicles to see the worker from a distance, for example, There has been proposed a flare cylinder that can be dropped onto the road from inside a dedicated vehicle to perform the above-mentioned arrangement work, as disclosed in Japanese Utility Model Laid-Open No. 57-131785 or Japanese Utility Model Laid-Open No. 57-131786. These flaming cylinders are provided with a rolling prevention measure in which one or several rings or pipes each having a rolling-preventing projection are fitted and fixed to the outer periphery.

【０００４】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

一般的な円筒状の従来例は、投下すると横倒し状態で路上を転がり、配置すべ き場所から大きく離れてしまうので、道路管理者や交通警察官が専用車両から降 り、目指す場所に起立状態で置かざるを得ず、配置作業に危険がともなうという 問題点がある。 In the case of conventional general cylindrical shape, when dropped, it rolls sideways in the state of falling sideways and greatly separates from the place where it can be placed, so road managers and traffic police officers descend from the dedicated vehicle and stand up at the intended place. There is a problem that there is no choice but to place it and the placement work is dangerous.

【０００５】 また、転がり防止策を施した従来例にあっては、転がり防止用のリングやパイ プ体を、投下の衝撃に耐える強さや弾力性を有するだけでなく、発炎薬の燃焼部 分に対応する部分のみが燃焼する材料、すなわち、発炎薬の燃焼熱等の他からの 熱の供給により燃焼し、熱の供給が絶たれると消火し延焼しない、いわゆる自己 消火性を有する材料で構成しなければならない。したがって、該材料の選択に困 難性があるうえ、リングやパイプ体の別途製造と、これらと発炎筒との固着手段 の工夫とが必要となり、工作の煩雑さ、余分な手間及び製造費が増大するという 問題点があった。In addition, in the conventional example in which the rolling prevention measures are taken, the rolling prevention ring and the pipe body not only have the strength and elasticity to withstand the impact of dropping, but also the burning portion of the flammable agent. A material that burns only the portion corresponding to the amount of heat, that is, a material that burns when heat is supplied from other sources, such as the heat of combustion of a flammable agent, and extinguishes when the heat supply is cut off and does not spread Must consist of Therefore, it is difficult to select the material, and it is necessary to separately manufacture the ring and the pipe body and devise a means for fixing the ring and the pipe body to the flaming cylinder, which increases the complexity of the work, extra labor and manufacturing cost. There was a problem to do.

【０００６】 本考案は、前記各問題点を解消することを課題とし、かつ該課題を解決した信 号発炎筒を提供することを目的とする。An object of the present invention is to solve each of the above problems, and an object thereof is to provide a signal flare tube which solves the problems.

【作用】[Action]

以上のように成した信号発炎筒１あるいは信号発炎筒２０あるいは信号発炎筒 ３０の使用にあたっては、先ず、キャップ９を外し、そのすり付け薬８で発火薬 ７をすって発火させる。発火するとその火は、伝火薬６に伝わり、さらに該伝火 薬６から前記発炎薬５に伝わって燃焼が開始される。このように、発炎薬５の燃 焼が始まると、前記口せん２が燃えて消滅した後、発炎薬５が、遠方より容易に 視認しうる炎と煙をあげながら、徐々に筒体４あるいは筒体２１あるいは筒体３ １の他端側の底せん３に向かって燃焼する。そして、道路管理者や交通警察官が 、緩走行する専用車両内から、前述のように着火した信号発炎筒１あるいは信号 発炎筒２０あるいは信号発炎筒３０を所定の路上に投下すると、断面形状が、三 角形あるいは半円形あるいは四角形であるから、路上を転がることなく目指す配 置地点で停止し、煙と炎を上げて燃焼する。したがって、一般車両のドライバー は、夜間であれば前記信号発炎筒１あるいは信号発炎筒２０あるいは信号発炎筒 ３０の炎を、また昼間であれば同じく煙を遠方より視認し、通行禁止を示す交通 規制標識等を設置中であること等を容易に知ることができる。 In using the signal flare cylinder 1, the signal flare cylinder 20 or the signal flare cylinder 30 constructed as described above, first, the cap 9 is removed, and the igniting agent 7 is scraped off by the rub 8 to ignite. When ignited, the fire is transmitted to the transfer charge 6, and further transferred from the transfer charge 6 to the flame release charge 5 to start combustion. In this way, when the burning of the flame-retardant drug 5 begins, the mouthpiece 2 burns and disappears, and then the flame-retardant drug 5 gradually raises the flame and smoke that can be easily seen from a distance, and gradually becomes a cylindrical body. 4 or the cylinder body 21 or the cylinder body 31 is burned toward the bottom wall 3 on the other end side. Then, when the road administrator or the traffic police officer drops the signal igniting tube 1, the signal igniting tube 20 or the signal igniting tube 30 which has been ignited as described above from the inside of the slow-moving dedicated vehicle, the cross-sectional shape is a triangle. Alternatively, since it is a semi-circle or a square, it stops at the desired location without rolling on the road, raises smoke and flames, and burns. Therefore, the driver of a general vehicle visually recognizes the flame of the signal flame tube 1, the signal flame tube 20 or the signal flame tube 30 at night, and the smoke from the distance in the daytime, and displays a traffic control sign indicating the prohibition of traffic. You can easily know that it is being installed.

【実施例】【Example】

以下に、本考案を交通規制標識設置中であることを知らせるための信号発炎筒 に適用した好適な第１実施例を添付図面の図１及び図２に基づいて詳細に説明す る。ここにおいて、図１は縦断正面図、図２は一部を破断した平面図である。 Hereinafter, a first preferred embodiment in which the present invention is applied to a signal flare for informing that a traffic control sign is being installed will be described in detail with reference to FIGS. 1 and 2 of the accompanying drawings. Here, FIG. 1 is a vertical sectional front view, and FIG. 2 is a partially cutaway plan view.

【００１２】 図１及び図２に示したように、第１実施例による信号発炎筒１は、長手方向に 伸びる三つの稜部ａ−１，ｂ−１，ｃ−１を有し、口せん２と底せん３によって 両端を閉塞した、断面形状が三角形の筒体４と、該筒体４内に充填した発炎薬５ と、該発炎薬５に前記口せん２を貫通させて埋設した伝火薬６と、口せん２外部 に露出するよう、前記伝火薬６と連繋すべく一体形成した発火薬７と、口せん２ 側の筒体４外周に取り外し可能に被冠し得るよう断面形状を三角形に形成した、 すり付け薬８を外周に帯状に巻いたキャップ９とから構成する。As shown in FIGS. 1 and 2, the signal flare tube 1 according to the first embodiment has three ridges a-1, b-1, c-1 extending in the longitudinal direction, and the mouthpiece 2 And a bottom plug 3, both ends of which are closed, and a tubular body 4 having a triangular cross-section, a flame-retardant 5 filled in the barrel 4, and the mouth-plug 2 penetrating and embedded in the flame-retardant 5. The transfer charge 6 and the pyrotechnic charge 7 integrally formed so as to be exposed to the outside of the mouthpiece 2 so as to be connected to the transfer charge 6 and the cross-sectional shape so that the outer periphery of the tubular body 4 on the side of the mouthpiece 2 can be detachably capped. Is formed in a triangular shape, and is composed of a scraping agent 8 and a cap 9 wound around the outer circumference in a band shape.

【００１３】 前記口せん２、底せん３及び筒体４は、発炎薬５の燃焼熱等の他からの熱の供 給で燃焼し、熱の供給が絶たれると消火し延焼しない性質、いわゆる自己消火性 を有する紙で構成されており、発炎薬５の燃焼部分に対応する部分のみが燃焼し 、発炎薬５の未燃焼部分に対応する部分には延焼しないようになっている。すな わち、筒体４が発炎薬５の燃焼に沿って燃焼し消滅するから、発炎薬５の燃焼部 分は常に外部に露出し、また未燃焼部分は筒体５内に保持された状態になるので ある。The mouthpiece 2, the bottom piece 3 and the cylindrical body 4 are burned by the supply of heat from other sources such as the combustion heat of the flame-retardant 5 and extinguish when the supply of heat is cut off and the fire does not spread. It is made of so-called self-extinguishing paper, so that only the part corresponding to the burned part of the flaming agent 5 burns, and the part corresponding to the unburned part of the flaming agent 5 does not burn. . That is, since the tubular body 4 burns and disappears along with the combustion of the flaming agent 5, the burning portion of the flaming agent 5 is always exposed to the outside, and the unburned portion is retained in the tubular body 5. It will be in the state where it was done.

【００１４】 次に、前記第１実施例の使用方法を説明する。先ず、キャップ９を外し、その すり付け薬８で発火薬７をすって発火させる。火は、伝火薬６に伝わり、さらに 該伝火薬６から前記発炎薬５に伝わって燃焼が開始される。このように、発炎薬 ５の燃焼が始まると、前記口せん２が燃えて消滅した後、発炎薬５が、遠方より 容易に視認しうる炎と煙をあげながら、徐々に円筒４の他端側の底せん３に向か って燃焼する。なお、この第１実施例の場合、燃焼時間は７〜８分間である。し たがって、道路管理者または交通警察官が、緩走行する専用車両内から前述のよ うに着火した信号発炎筒１を所定の路上に投下すると、断面形状が三角形である から、路上を転がることなく目指す配置地点で停止し、かつ炎と煙を上げて燃焼 する。一般車両のドライバーは、夜間であれば前記信号発炎筒１の炎を、また昼 間であれば同じく煙を遠方より視認し、通行禁止を示す交通規制標識を設置中で あることが容易にわかる。Next, a method of using the first embodiment will be described. First, the cap 9 is removed, and the igniting charge 7 is rubbed with the rub 8 to ignite. The fire is transmitted to the transfer charge 6, and is further transmitted from the transfer charge 6 to the flaming charge 5 to start combustion. In this way, when the burning of the flame-retardant drug 5 starts and the mouthpiece 2 burns and disappears, the flame-retardant drug 5 gradually raises the flame and smoke that can be easily seen from a distance, and gradually It burns toward the bottom wall 3 on the other end side. In the case of the first embodiment, the burning time is 7 to 8 minutes. Therefore, when the road administrator or traffic police officer drops the signal ignition tube 1 ignited as described above on the predetermined road from inside the slow-moving dedicated vehicle, the cross-sectional shape is triangular, so that it does not roll on the road. Stop at the intended location and burn with flames and smoke. The driver of a general vehicle can easily see that the flame of the signal flare cylinder 1 is seen at night and the smoke is seen from a distance at daytime, and that a traffic control sign indicating that the traffic is prohibited is being installed.

【００１５】 以上のように、前記第１実施例の信号発炎筒１は、断面形状が三角形なので、 横倒し状態でも路上を転がりにくく、例えば、専用車両内から所定の路上に投下 して、ほぼ目指す配置場所に停止させることが可能であり、特に高速道路におけ る配置作業を安全に行うことができるという利点がある。As described above, since the signal flare tube 1 of the first embodiment has a triangular cross-sectional shape, it does not easily roll on the road even when it is in a sideways state. It has the advantage that it can be stopped at a location, and the placement work can be performed safely, especially on expressways.

【００１６】 また、本考案の第２実施例を添付図面の図３（縦断正面図）に基づいて説明す る。この第２実施例を説明するにあたって、特徴となる筒体の構成のみを詳細に 説明し、前記第１実施例と同様の構成についてはその説明を省略し、図３に前記 第１実施例と同じ符号を付すに止める。A second embodiment of the present invention will be described with reference to FIG. 3 (longitudinal front view) of the accompanying drawings. In describing the second embodiment, only the configuration of the characteristic cylindrical body will be described in detail, and the description of the configuration similar to that of the first embodiment will be omitted.

【００１７】 図３に示したように、第２実施例の信号発炎筒２０は、その長手方向に伸びる 二つの稜部ａ−２，ｂ−２を有し、断面形状が半円形の筒体２１を用いたことを 特徴とするもので、前記第１実施例と同様に、横倒し状態でも路上を転がりにく く、例えば、専用車両内から所定の路上に投下して、目指す場所に配置すること が可能である。As shown in FIG. 3, the signal-flaming cylinder 20 of the second embodiment has two ridges a-2 and b-2 extending in the longitudinal direction thereof, and a cylindrical body 21 having a semicircular cross section. Similar to the first embodiment, it is hard to roll on the road even in a sideways state. For example, the vehicle should be dropped on a predetermined road from within a dedicated vehicle and placed at the intended location. Is possible.

【００１８】 さらに、本考案の第３実施例を添付図面の図４（縦断正面図）に基づいて説明 する。この第３実施例を説明するにあたって、特徴となる筒体の構成のみを詳細 に説明し、前記第１，２実施例と同様の構成についてはその説明を省略し、図４ に前記第１，２実施例と同じ符号を付すに止める。Further, a third embodiment of the present invention will be described with reference to FIG. 4 (longitudinal front view) of the accompanying drawings. In describing the third embodiment, only the configuration of the characteristic cylindrical body will be described in detail, and the description of the configurations similar to those of the first and second embodiments will be omitted. In FIG. The same reference numerals as those in the second embodiment are used for the description.

【００１９】 図４に示したように、第３実施例の信号発炎筒３０は、その長手方向に伸びる 四つの稜部ａ−３，ｂ−３，ｃ−３，ｄ−３を有し、断面形状が四角形の筒体３ １を用いたことを特徴とするもので、前記第１，２実施例と同様に、横倒し状態 でも路上を転がりにくく、例えば、専用車両内から所定の路上に投下して、目指 す場所に配置可能である。As shown in FIG. 4, the signal flame tube 30 of the third embodiment has four ridges a-3, b-3, c-3, d-3 extending in the longitudinal direction thereof, and has a cross section. A cylindrical body 31 having a quadrangular shape is used. Like the first and second embodiments, it is difficult to roll on the road even in a sideways state. For example, it is dropped from a private vehicle onto a predetermined road. It can be placed at a desired location.

【００２０】 なお、本考案は、前記第１，２，３実施例に何ら限定されるものではなく、例 えば、交通規制標識設置中であることを知らせるためだけでなく、他の目的に応 じて適用してもよい。また、筒体は、その長手方向に伸びる少なくとも二つの稜 部を有し、該両稜部間の筒面の少なくとも一つが、該両稜部間の仮想平面上か、 または該仮想平面より内側に存置するものであればよく、例えば、断面形状が、 菱形や台形や三日月形等の他の形状のものを用いてもよい。さらに、筒体４，２ １，３１と口せん２と底せん３は、紙に換えて、自己消火性を有する合成樹脂あ るいは布等で構成してもよい。The present invention is not limited to the first, second, and third embodiments.
