Description

本発明は、鉄道の線路脇等に布設されて、その内部にケーブル等を収納するのに用いられるトラフに関するものである。   The present invention relates to a trough that is laid on the side of a railway track or the like and is used to store a cable or the like therein.

鉄道の線路脇等に布設されて、その内部に通信用ケーブルや電力ケーブル等が収納されるトラフは、通常、左右の側壁と底壁とを有し上部が開口しているトラフ本体と、該トラフ本体の開口を塞ぐ蓋とからなっている。
このトラフを、例えば鉄道の線路に沿って線路脇に布設する場合、従来はコンクリート製トラフを使用することが多かった。
しかしながら最近では、この重いコンクリート製のトラフに代えて、軽量で布設作業が容易なプラスチック製のトラフが使用されるようになってきている。またこのプラスチックとして、例えばプラスチック製品の廃材から再生した再生プラスチック、すなわちリサイクルプラスチックも度々使用されるようになって来ている。 A trough that is laid on the side of a railroad track and accommodates a communication cable, a power cable, and the like is usually a trough body that has left and right side walls and a bottom wall, and an upper portion that is open. It consists of a lid that closes the opening of the trough body.
In the case where this trough is laid on the side of a track along a railroad track, for example, a concrete trough has often been used in the past.
Recently, however, instead of the heavy concrete trough, a plastic trough that is lightweight and easy to install has been used. Also, as this plastic, for example, recycled plastic regenerated from waste plastic products, that is, recycled plastic, is often used.

この種のものとして、例えば４００〜５００ｍｍ程度の長さのプラスチック製のトラフ同士を、その端部で接続しながら長手方向に延長していくものが知られている（特許文献１）。
この特許文献１に記載のトラフ１は、図５に示すように、左右の側壁２、３と、底壁４とを有していて、上部が開口しているトラフ本体５と、トラフ本体５の開口を塞ぐ蓋６とからなっている。
そしてこのトラフ１同士を接続して長手方向に延長する場合には、図５に示すように、一方の側のトラフ本体５の一端側の底壁４に設けられた突縁１１を、図６に示す接続する他方の側のトラフ本体５の他端部の底壁４に設けられている溝１２に、図７に示すように嵌入して、順次長手方向にトラフ本体５同士を接続してその長さを延ばしていくようになっている。尚、蓋６は図７では省略されているが、このようにして長手方向に所望長さ延長したトラフ内にケーブル等が収納された後、開口部には蓋６が被せられる。 As this type, for example, a plastic trough having a length of about 400 to 500 mm is extended in the longitudinal direction while being connected at its end (Patent Document 1).
As shown in FIG. 5, the trough 1 described in Patent Document 1 includes left and right side walls 2, 3 and a bottom wall 4, and a trough body 5 having an open top, and a trough body 5. And a lid 6 for closing the opening.
And when connecting these troughs 1 and extending in a longitudinal direction, as shown in FIG. 5, the protruding edge 11 provided in the bottom wall 4 of the one end side of the trough main body 5 of one side is shown in FIG. 7 is inserted into the groove 12 provided in the bottom wall 4 of the other end of the trough body 5 on the other side to be connected as shown in FIG. 7, and the trough bodies 5 are sequentially connected in the longitudinal direction. The length has been extended. Although the lid 6 is omitted in FIG. 7, after the cable or the like is housed in the trough thus extended in the longitudinal direction by a desired length, the lid 6 is put on the opening.

特開２０００−５５２４０号公報JP 2000-55240 A

ところで前述した特許文献１に記載のトラフの場合、図７に示すように複数のトラフ本体５が接続され所望の長さに達した後に、トラフ本体５内にケーブル等が収納されるが、このようなトラフ１を長期にわたって使用していると、前述した溝１２内に雨水等の水が溜まる恐れがある。
溝１２内に水が溜まると、そこに苔等の植物が発生し、これが起点になってトラフ本体５の内部にも植物が発生し、トラフ１内へのケーブルの通線等の邪魔になる、といった問題が起こる恐れがある。 By the way, in the case of the trough described in Patent Document 1 described above, after a plurality of trough main bodies 5 are connected and reach a desired length as shown in FIG. 7, cables and the like are stored in the trough main body 5. When such a trough 1 is used over a long period of time, there is a risk that water such as rainwater may accumulate in the groove 12 described above.
When water accumulates in the groove 12, plants such as moss are generated there, and this is the starting point and plants are also generated inside the trough body 5, which obstructs the passage of cables into the trough 1. There is a risk of problems such as.

そこで本発明の目的は前述の問題に鑑み、トラフ内部に水の溜まる恐れのない、それ故、トラフ内部に苔等の植物の発生し難いトラフを提供することにある。   In view of the above-described problems, an object of the present invention is to provide a trough in which water does not accumulate inside the trough, and therefore plants such as moss are hardly generated inside the trough.

前記目的を達成すべく本願発明の請求項１記載のトラフは、左右の側壁と底壁とを有し上部が開口しているトラフ本体と、該トラフ本体の開口を塞ぐ蓋とからなり、前記トラフ本体同士は長手方向に接続されて延長可能になっているトラフにおいて、前記トラフ本体の一端部の外面に周方向に突縁と溝が、前記突縁が端部側に位置するように隣接して形成され、前記トラフ本体の他端部の内面に周方向に突縁と溝が、前記突縁が端部側に位置するように隣接して形成され、前記一端部の溝は他端部の突縁が緩く嵌入できる大きさに、前記他端部の溝は一端部の突縁が緩く嵌入できる大きさに形成されていて、かつ前記他端部の溝は左右の側壁のみまたは左右の側壁と底壁の一部のみに形成されていることを特徴とするものである。   In order to achieve the above object, a trough according to claim 1 of the present invention comprises a trough body having left and right side walls and a bottom wall and having an open top, and a lid for closing the opening of the trough body, The trough bodies are connected to each other in the longitudinal direction so that the troughs can be extended. And a protruding edge and a groove are formed on the inner surface of the other end of the trough body in the circumferential direction so that the protruding edge is located on the end side, and the groove of the one end is the other end. The groove at the other end is sized so that the protrusion at the other end can be loosely inserted, and the groove at the other end is formed at a size that allows the protrusion at the other end to be loosely inserted. It is characterized in that it is formed only on a part of the side wall and the bottom wall.

このようにしてなる本願発明の請求項１記載のトラフによれば、トラフ本体の一方の端部の底壁に設けられていた溝を全部なくすか、少なくとも一部のみ形成するにとどめたことにより、雨水等外部から仮にトラフ内に水が侵入してきたとしても、水は溜まる場所がないため、トラフ外部に抜ける。そのため苔等の植物がトラフ内部に発生し難くなり、長期にわたってケーブル通線等の作業を支障なく、行うことができる。   According to the trough according to claim 1 of the present invention thus formed, the groove provided in the bottom wall of one end of the trough body is completely eliminated or only at least a part thereof is formed. Even if water enters the trough from the outside, such as rain water, the water does not have a place to accumulate, and therefore it goes out of the trough. Therefore, plants such as moss are less likely to be generated inside the trough, and work such as cable wiring can be performed without hindrance over a long period of time.

また本願発明の請求項２記載のトラフは、左右の側壁と底壁とを有し上部が開口しているトラフ本体と、該トラフ本体の開口を塞ぐ蓋とからなり、前記トラフ本体同士は長手方向に接続されて延長可能になっているトラフにおいて、前記トラフ本体の一端部の外面に周方向に突縁と溝が、前記突縁が端部側に位置するように隣接して形成され、前記トラフ本体の他端部の内面に周方向に突縁と溝が、前記突縁が端部側に位置するように隣接して形成され、前記一端部の溝は他端部の突縁が緩く嵌入できる大きさに、前記他端部の溝は一端部の突縁が緩く嵌入できる大きさに形成されていて、かつ前記他端部の底壁に設けられた溝の底部または側面下部にはトラフ本体の外部に貫通する水抜き穴が設けられていることを特徴とするものである。   The trough according to claim 2 of the present invention comprises a trough main body having left and right side walls and a bottom wall and having an upper opening, and a lid for closing the opening of the trough main body. In the trough that is connected in the direction and can be extended, a projecting edge and a groove are formed on the outer surface of one end of the trough body in the circumferential direction so that the projecting edge is located on the end side, A projecting edge and a groove are formed on the inner surface of the other end of the trough body in the circumferential direction so that the projecting edge is located on the end side, and the groove on the one end has a projecting edge on the other end. The groove at the other end is sized so that it can be loosely fitted, and the protruding edge at one end is sized so that it can be loosely fitted, and at the bottom or lower side of the groove provided on the bottom wall of the other end. Is characterized in that a water drain hole penetrating the outside of the trough body is provided.

このようにしてなる本願発明の請求項２記載のトラフによれば、水の溜まり易い前記他端部の溝の底部に、すなわち溝が形成されている底壁にトラフ本体の外部に貫通する水抜き穴が設けられているので、雨水等外部からトラフ内に水が侵入してきたとしても、水はこの水抜き穴から外部に排出される。そのため苔等の植物がトラフ内部に発生し難くなり、長期にわたってケーブル通線等の作業を支障なく、行うことができる。   According to the trough according to claim 2 of the present invention thus configured, the water penetrating to the outside of the trough main body at the bottom of the groove at the other end where water easily accumulates, that is, at the bottom wall where the groove is formed. Since a drain hole is provided, even if water enters the trough from the outside, such as rainwater, the water is discharged to the outside through the drain hole. Therefore, plants such as moss are less likely to be generated inside the trough, and work such as cable wiring can be performed without hindrance over a long period of time.

以上のように本発明によれば、トラフ内部に水の溜まる恐れのない、それ故、トラフ内部に苔等の植物の発生し難いトラフを提供することができる。   As described above, according to the present invention, it is possible to provide a trough in which water does not accumulate inside the trough, and therefore plants such as moss are hardly generated inside the trough.

以下本願発明のトラフの各実施例を図１〜図４を用いて詳細に説明する。   Hereinafter, embodiments of the trough of the present invention will be described in detail with reference to FIGS.

図１、図２は本願発明のトラフの第一実施例を示すものである。図１（Ａ）は平面図、図１（Ｂ）は側面図、図１（Ｃ）は正面図、そして図１（Ｄ）は背面図である。また図２は前記図１のトラフを長手方向に接続した状態を示すもので、図２（Ａ）は平面図、図２（Ｂ）は側面図である。   1 and 2 show a first embodiment of the trough of the present invention. 1A is a plan view, FIG. 1B is a side view, FIG. 1C is a front view, and FIG. 1D is a rear view. 2 shows a state in which the troughs of FIG. 1 are connected in the longitudinal direction. FIG. 2 (A) is a plan view and FIG. 2 (B) is a side view.

図１が示すように本願発明のトラフは、リサイクルプラスチックからなる左右の側壁と底壁とを有し上部が開口しているトラフ本体１０と、該トラフ本体１０の開口を塞ぐ蓋１２とからなっている。ここで蓋１２もリサイクルプラスチックからなるが、この蓋１２は本願発明の要点ではないので、図２に２点鎖線で簡単に示すにとどめることにする。   As shown in FIG. 1, the trough of the present invention includes a trough body 10 having left and right side walls and a bottom wall made of recycled plastic and having an upper opening, and a lid 12 that closes the opening of the trough body 10. ing. Here, the lid 12 is also made of recycled plastic. However, since the lid 12 is not the gist of the present invention, it will be simply shown by a two-dot chain line in FIG.

さて図１、図２に示すトラフ本体１０は、一端部の外面に周方向に突縁１４と溝１６が、突縁１４が端部側に位置するように隣接して形成され、かつ他端部の内面に周方向に突縁１８と溝２０が、突縁１８が端部側に位置するように隣接して形成されており、一端部の溝１６は他端部の突縁１８が緩く嵌入できる大きさに、同様に他端部の溝２０は一端部の突縁１４が緩く嵌入できる大きさに形成されている。
そしてこの第一実施例の特徴は、前記他端部の溝２０は、図１（Ａ）や図１（Ｄ）に端的に示すように、左右の側壁のみに設けられていて、底壁には設けられていない点にある。すなわち、底壁には左右の側壁に設けられているような突縁１８が設けられていない。 The trough body 10 shown in FIGS. 1 and 2 is formed with a protruding edge 14 and a groove 16 on the outer surface of one end in the circumferential direction so that the protruding edge 14 is located on the end side, and the other end. A protruding edge 18 and a groove 20 are formed on the inner surface of the portion in the circumferential direction so that the protruding edge 18 is located on the end side, and the protruding edge 18 at the other end of the groove 16 at one end is loose. Similarly, the groove 20 at the other end is formed in such a size that the protruding edge 14 at one end can be loosely inserted.
The first embodiment is characterized in that the groove 20 at the other end is provided only on the left and right side walls as shown in FIG. 1 (A) and FIG. 1 (D). Is not provided. That is, the bottom wall is not provided with the protruding edge 18 as provided on the left and right side walls.

このように底壁に溝２０がないため、外部から仮に雨水等の水がトラフ本体１０内に侵入したとしても、その水はトラフ本体１０内に溜まるところがないため、トラフ本体１０の外に流れ出ていく。よって苔等の植物がトラフ内部に発生し難くなり、長期にわたってケーブル通線等の作業を支障なく、行うことができる。
尚、図１、図２に示す第一実施例においては底壁の溝２０だけでなく、この溝２０に嵌る予定の突縁１４も、側壁に設けられている突縁１４のみ残して底壁に接触する部分の突縁１４は無くしているが、底壁の溝２０さえなくせば、この突縁１４はそのまま残してもよい。いずれの場合にも、最終的にトラフ本体１０の開口部には蓋１２を被せる関係上、接続した隣接するトラフ本体１０の高さが一致するようにすることが必要である。 Since there is no groove 20 on the bottom wall in this way, even if rain water or the like enters the trough body 10 from the outside, the water does not collect in the trough body 10 and flows out of the trough body 10. To go. Therefore, plants such as moss are less likely to be generated inside the trough, and work such as cable wiring can be performed without hindrance over a long period of time.
In the first embodiment shown in FIGS. 1 and 2, not only the groove 20 on the bottom wall but also the protruding edge 14 to be fitted into the groove 20 leaves only the protruding edge 14 provided on the side wall. The protruding edge 14 at the portion that contacts the surface is eliminated, but the protruding edge 14 may be left as it is as long as the groove 20 on the bottom wall is eliminated. In any case, it is necessary to match the heights of the connected adjacent trough bodies 10 because the lid 12 is finally covered with the opening of the trough body 10.

図３に本願発明の第二実施例を示す。図３において、前記第一実施例と同じ部分には同一番号を付し、詳細な説明は特徴点のみとし、それ以外は説明を省略する。
この第二実施例の特徴は、図３（Ａ）や図３（Ｄ）に端的に示されているように、前記他端部の溝２０は左右の側壁の高さ方向には全長にわたって形成されているものの、底壁にあってはその一部だけにのみに形成されている点にある。換言すると、底壁には突縁１８が底壁の一部にしか設けられていなくて、この底壁に設けられた突縁１８の両側には溝２０は存在していない。
そのため外部から雨水等の水がトラフ本体１０内に侵入したとしても、その水は底壁の一部にのみ設けられた突縁１８の両側からトラフ本体１０の外部へと流れ出す。
このようにトラフ本体１０の内部に侵入した水は、トラフ本体１０内に溜まることができないため、苔等の植物がトラフ内部に発生し難くなり、長期にわたってケーブル通線等の作業を支障なく、行うことができる。 FIG. 3 shows a second embodiment of the present invention. In FIG. 3, the same parts as those in the first embodiment are denoted by the same reference numerals, detailed description is made only for feature points, and description is omitted for other parts.
The second embodiment is characterized in that the groove 20 at the other end is formed over the entire length in the height direction of the left and right side walls as shown in FIG. 3 (A) and FIG. 3 (D). However, the bottom wall is formed only on a part of the bottom wall. In other words, the projecting edge 18 is provided on only a part of the bottom wall on the bottom wall, and the groove 20 does not exist on both sides of the projecting edge 18 provided on the bottom wall.
Therefore, even if water such as rainwater enters the trough body 10 from the outside, the water flows out of the trough body 10 from both sides of the projecting edge 18 provided only on a part of the bottom wall.
Thus, water that has entered the inside of the trough body 10 cannot accumulate in the trough body 10, so that plants such as moss are less likely to be generated inside the trough, and there is no hindrance to work such as cable wiring over a long period of time. It can be carried out.

この第二実施例の場合には、底壁にも一部とはいえ溝２０が存在するため、トラフ本体１０同士を図２に示すようにその端部同士を接続して長手方向に延長していく場合、一方のトラフ本体１０の他端部の溝２０に他方のトラフ本体１０の一端部の突縁１４を嵌め込む際、突縁１４を両側壁方向と底壁方向の三方向で溝２０内に確保できるので、トラフ本体１０同士をよりがたつきを少なく組み付けることができる利点がある。   In the case of this second embodiment, since the groove 20 exists in the bottom wall, though partly, the trough bodies 10 are connected to each other as shown in FIG. 2 and extended in the longitudinal direction. When fitting the projecting edge 14 at one end of the other trough body 10 into the groove 20 at the other end of one trough body 10, the projecting edge 14 is grooved in the three directions of both side walls and the bottom wall. Therefore, the trough bodies 10 can be assembled with less backlash.

図４に本願発明の第三実施例を示す。図４においても図１〜図３に示した前記第一、第二実施例と同じ部分には同一番号を付し、詳細な説明は特徴点のみとし、それ以外は説明を省略することにする。
この第三実施例の特徴は、前述した２つの実施例と異なり、図４（Ａ）や図４（Ｄ）に示すように、前記他端部の底壁にも溝２０を形成し、その代わりに底壁に設けたこの溝２０の底部に、トラフ本体１０の外部に貫通する水抜き穴３０を一個または複数個設けた点にある。
このように底壁に設けた溝２０に水抜き穴３０を設けたため、外部から仮に雨水等がトラフ本体１０内に侵入したとしても、その水はこの水抜き穴３０からトラフ本体１０の外部に抜けていく。よって苔等の植物がトラフ内部に発生し難くなり、長期にわたってケーブル通線等の作業を支障なく、行うことができる。
尚、図４においては水抜き穴３０を溝２０の底部に設けているが、溝２０の側面下部にこの水抜き穴３０を設けて溝２０内に水が溜まらないようにしてもよい。 FIG. 4 shows a third embodiment of the present invention. Also in FIG. 4, the same parts as those in the first and second embodiments shown in FIGS. 1 to 3 are denoted by the same reference numerals, detailed description is made only for feature points, and description is omitted otherwise. .
Unlike the two embodiments described above, the third embodiment is characterized in that a groove 20 is formed in the bottom wall of the other end as shown in FIGS. 4 (A) and 4 (D). Instead, one or a plurality of drain holes 30 penetrating to the outside of the trough body 10 are provided at the bottom of the groove 20 provided on the bottom wall.
Since the drainage hole 30 is provided in the groove 20 provided in the bottom wall in this way, even if rainwater or the like enters the trough body 10 from the outside, the water passes from the drainage hole 30 to the outside of the trough body 10. Go through. Therefore, plants such as moss are less likely to be generated inside the trough, and work such as cable wiring can be performed without hindrance over a long period of time.
In FIG. 4, the drain hole 30 is provided at the bottom of the groove 20. However, the drain hole 30 may be provided at the lower side of the groove 20 so that water does not accumulate in the groove 20.

この第三実施例の場合も、前記第二実施例の場合同様に、左右の側壁のみならず底壁にも溝２０が存在するため、トラフ本体１０同士を図２に示すようにその端部同士を接続して長手方向に延長していく場合、一方のトラフ本体１０の他端部の溝２０に他方のトラフ本体１０の一端部の突縁１４を嵌め込む際、突縁１４を両側壁方向と底壁方向の三方向で溝２０内に確保できるので、トラフ本体１０同士をよりがたつきを少なく組み付けることができる。   Also in the case of the third embodiment, as in the case of the second embodiment, since the groove 20 is present not only on the left and right side walls but also on the bottom wall, the trough bodies 10 are arranged at their end portions as shown in FIG. When connecting each other and extending in the longitudinal direction, when the protruding edge 14 of one end of the other trough body 10 is fitted into the groove 20 of the other trough body 10, Since the groove 20 can be secured in the three directions of the direction and the bottom wall direction, the trough bodies 10 can be assembled with less backlash.

前述したようにいずれの実施例においても、仮に外部からトラフ本体１０内に水が侵入しても、その水はトラフ本体１０内に留まることなく外部に流れ出していき、トラフ１０本体内にいつまでも留まっていることがない。それ故、苔等の植物がトラフ内部に発生し難くなり、長期にわたってケーブル通線等の作業を支障なく、行うことができる。   As described above, in any of the embodiments, even if water enters the trough body 10 from the outside, the water flows out without staying in the trough body 10 and stays in the trough 10 body forever. There is never. Therefore, plants such as moss are less likely to be generated inside the trough, and work such as cable wiring can be performed without hindrance over a long period of time.

ところで前述した本願発明の各トラフは、軽量にして布設作業性を高めるため、コンクリート製のものよりプラスチック製である方が好ましく、さらには環境問題に配慮してリサイクルプラスチック製であればより好ましい。尚、トラフ本体１０をプラスチック製にした場合でも、蓋１２は風に飛ばされ難いように重いコンクリート製にする等、布設条件に応じて両者を適宜組み合わせることもできる。
また第一実施例や第二実施例に、第三実施例を組み合わせて、例えば第二実施例のものに第三実施例の水抜き穴３０を設ければ、より確実に侵入した水をトラフ外部に逃がすことができる。 By the way, each trough of the present invention described above is preferably made of plastic rather than concrete in order to reduce the weight and improve the laying workability, and more preferably recycled plastic in consideration of environmental problems. Even when the trough body 10 is made of plastic, the lid 12 may be made of heavy concrete so as not to be blown away by the wind.
If the third embodiment is combined with the first embodiment or the second embodiment and the drain hole 30 of the third embodiment is provided in the second embodiment, for example, the water that has entered the trough can be more reliably trapped. Can escape to the outside.
