Description

本発明は、上方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トラフ用蓋とからなる、例えば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に使用されるトラフ蓋固定用部材に関するものである。   The present invention comprises a trough body that is open at the top and a trough lid that closes the opening of the trough body. The present invention relates to a trough lid fixing member used for a stored trough.

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、左右の側壁部と底壁部とを有し上方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トラフ用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。 A trough that is laid on the side of a railroad track, and in which a communication cable, a power cable, etc. are stored, has a trough body that has left and right side walls and a bottom wall, and has an open top, It consists of a trough 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.

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、軽量で布設作業が行い易い合成樹脂製のトラフが使用されるようになってきている。またこの合成樹脂として、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。この種のものとして、例えば所定長さの合成樹脂製のトラフ同士を、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に記載のトラフのトラフ本体は、前述したように合成樹脂製で、その形状は、左右の側壁部と底壁部とからなり上方が開口する断面略Ｕ字状をしている。 However, recently, instead of this heavy concrete trough, a synthetic resin trough that is lightweight and easy to lay is being used. In addition, as this synthetic resin, for example, recycled plastic regenerated from waste plastic products, that is, recycled plastic, has been frequently used. As this kind, for example, a synthetic resin trough having a predetermined length is extended in the longitudinal direction while being connected at its end (Patent Document 1).
The trough body of the trough described in Patent Document 1 is made of synthetic resin as described above, and the shape thereof is substantially U-shaped in cross section that is composed of left and right side walls and a bottom wall and opens upward. .

特開２０００−５５２４０号公報JP 2000-55240 A

トラフ本体及びトラフ用蓋がコンクリート製であった場合には、トラフ用蓋が重いため、トラフ本体に載置したトラフ用蓋が風等で動いたり、吹き飛ばされたりする恐れが少なかった。そのためトラフ本体とトラフ用蓋とを、敢えてトラフ用蓋が飛ばないように固定する必要はあまりなかった。
ところがトラフ本体及びトラフ用蓋を合成樹脂で形成した場合には、合成樹脂が軽量のため、両者をなんらかの方法で固定しないとトラフ用蓋が風等で飛ばされたり、トラフ本体から外れたりする恐れがある。 When the trough body and the trough lid were made of concrete, the trough lid was heavy, so that the trough lid placed on the trough body was less likely to move or blow away. Therefore, it was not necessary to fix the trough body and the trough lid so as to prevent the trough lid from flying.
However, when the trough body and the trough lid are made of synthetic resin, the synthetic resin is lightweight, so if both are not fixed in some way, the trough lid may be blown off by the wind or the trough body may come off. There is.

そこで本願発明者は先に、図６に示すようなトラフ本体と該トラフ本体の開口に載置したトラフ用蓋とを容易かつ確実に固定でき、また必要に応じて長いトラフのどの位置でもトラフ用蓋を容易に開けることのできるトラフ固定用クリップ３０を提案した（特願２００３−３２７０３０）。このトラフ固定用クリップ３０は、トラフ本体の側壁部に設けられた突起を把持する内側に付勢された断面略Ｕ字状の板バネ３１と、一端が前記板バネ３１に係止され他端が前記トラフ用蓋に設けられた係止部に係止されるフック３２とからなるものである。
Therefore, the inventor of the present application can easily fix the trough body and the trough lid mounted on the opening of the trough body as shown in FIG. A trough fixing clip 30 that can easily open the lid is proposed (Japanese Patent Application No. 2003-327030). The trough fixing clip 30 includes a leaf spring 31 having a substantially U-shaped cross section that is biased inwardly to hold a protrusion provided on a side wall portion of the trough body, and one end locked to the leaf spring 31 and the other end. Comprises a hook 32 which is locked to a locking portion provided on the trough lid.

このトラフ固定用クリップ３０によれば、トラフ本体と該トラフ本体に載置したトラフ用蓋とを、単に板バネ３１とフック３２からなるクリップという簡単な構造の部品で、しかも板バネ３１をトラフ本体側壁部の突起に係止させ、フック３２をトラフ用蓋に設けられている係止部に係止するだけで容易に固定できる。   According to this trough fixing clip 30, the trough body and the trough lid placed on the trough body are simply parts of a clip consisting of a leaf spring 31 and a hook 32, and the leaf spring 31 is attached to the trough. It can be easily fixed by simply engaging the protrusion on the side wall of the main body and engaging the hook 32 with the engaging portion provided on the trough lid.

しかし、このトラフ固定用クリップ３０を使用したところ、トラフを壁面に寄せて配置したり、トラフとトラフを並列に隙間無く並べた場合にはフック３２の開閉用のスペースを十分に取れず、トラフ固定用クリップ３０を取り付け難いという懸念が生じた。また、見た目に開閉方法が容易に察知でき、悪意を持った者等がトラフ用蓋を容易に開閉できてしまうという懸念が生じた。   However, when this trough fixing clip 30 is used, when the trough is arranged close to the wall surface or when the trough and the trough are arranged in parallel without a gap, a sufficient space for opening and closing the hook 32 cannot be taken. There was a concern that it was difficult to attach the fixing clip 30. Moreover, the opening and closing method can be easily detected visually, and there is a concern that a malicious person or the like can easily open and close the trough lid.

本発明はこのような問題点に鑑みてなされたもので、トラフを壁面に寄せて配置した場合等にもトラフ本体の開口に被せたトラフ用蓋をトラフ本体に容易かつ確実に固定することができ、固定した後には取り外し方法が容易に察知されないトラフ用蓋固定部材及びトラフを提供することを目的とする。 The present invention has been made in view of such problems, and it is possible to easily and surely fix the trough lid that covers the opening of the trough body to the trough body even when the trough is arranged close to the wall surface. An object of the present invention is to provide a trough lid fixing member and a trough which can be removed and cannot be easily detected after being fixed.

In order to achieve the above object, the trough lid fixing member and the trough fixing structure according to claim 1 of the present invention includes a bottom wall portion, two side wall portions, and further below the upper end of the side wall portion and in the middle of the side wall portion. A trough body made of a synthetic resin, comprising: a trough body that protrudes from an outer surface of the side wall portion; and a trough body that opens above the side wall portion; and a trough lid that covers the opening of the trough body. A trough lid fixing member and a trough fixing structure integrally formed by bending a metal plate for fixing the trough lid to the trough body, wherein the trough lid fixing member includes a top plate portion, two side plate portions, from made, the two side plate portions has a gap covering comfortably across the two side wall portions including an engagement portion of the trough body, to the side plate portion to the side wall of the trough body The leaf spring part that is locked to the provided locking part is shaped Is, the plate spring portion is formed by bending Oriri the side plate portion on the inner side of the side plate portion, and, at a connection near to the top plate portion and the side plate portion, at least the top plate or side plate portion A guide hole is provided so as to straddle either the top plate part or the side plate part,
When the trough lid fixing member is attached to the trough, the two side plate portions of the trough lid fixing member sandwich the two side walls including the locking portion of the trough main body so as to completely cover the trough main body. A state where the trough lid fixing member is covered from above the trough lid, the leaf spring portion is compressed and pushed below the locking portion provided on the side wall portion of the trough body, and the trough lid fixing member is attached to the trough. The leaf spring portion is hooked and locked to the locking portion of the trough body, and the side plate portion is pushed outwardly above the locking portion on the outside of the trough lid, so that the guide hole is operated. A trough lid fixing member and a trough fixing structure characterized in that a space into which a rod body can be inserted is formed .
According to a second aspect of the present invention, there is provided a method for attaching and detaching a trough lid fixing member in which a trough lid is fixed to a trough body. The trough lid fixing member includes a top plate portion and two side plate portions, and the two side plate portions are the trough body. An inward leaf spring portion is formed at the lower end of the side plate portion and is engaged with a locking portion provided on the side wall portion of the trough body. The trough lid fixing member is mounted on the trough using a trough lid fixing member provided with a guide hole in at least the top plate portion in the vicinity of the connecting portion between the top plate portion and the side plate portion. Sometimes, the two side plate portions of the trough lid fixing member cover the two side wall portions including the engaging portion provided in the middle of the side wall portion below the upper end of the side wall portion of the trough body. Trough lid fixing member for trough Covered from above, when the spring part pushing the lower locking portion provided in the side wall of the trough body while compressing the leaf spring portion engaged with the locking portion, remove the cover fixing member for the trough from trough In the vicinity of the connection between the top plate and the side plate, at least one of the top plate or the side plate, or the guide rod formed so as to straddle both the top plate and the side plate. And insert a part of the operating rod body into the side wall of the trough body and the other part into the edge part inside the guide hole in the top plate part or the upper edge part in the side plate part. Then, by tilting the operating rod body inward in the width direction, the edge portion serves as a fulcrum, and the side plate portion of the trough lid fixing member is pushed outward, and the leaf spring portion is formed on the trough body. Provided on the side wall It is characterized in that the removal of the trough lid fixing member in a state deviated from the locking portion upward.

このように、請求項１及び２の発明に用いるトラフ用蓋固定部材は、トラフ用蓋固定部材は２つの側板部がトラフ本体をすっぽり覆う間隔に配置されており、トラフ本体に載置したトラフ用蓋の上方からトラフ本体を覆うようにして装着させるので、トラフが壁面に寄せられていたり、複数のトラフを並行に並べた等で幅方向のスペースが確保できない場合でも、トラフ用蓋固定部材を装着することができる。また、バックル等を使用せずにトラフをすっぽり覆っているので、トラフ用蓋固定部材の取り外し方法が容易に察知されない。従って、悪意を持った者等がトラフ用蓋を容易に開口してトラフ内部のケーブルを切断してしまう等の懸念が生じ難い。
Thus, the trough lid fixing member used in the inventions of claims 1 and 2 is arranged such that the two side plate portions completely cover the trough body , and the trough lid fixing member is disposed on the trough body. The trough lid fixing member is installed so that the trough body is covered from above the lid for the trough, even if the trough is brought close to the wall surface or a space in the width direction cannot be secured by arranging a plurality of troughs in parallel. Can be worn. Further, since the trough is completely covered without using a buckle or the like, a method for removing the trough lid fixing member is not easily detected. Therefore, it is difficult for a malicious person or the like to easily open the trough lid and cut the cable inside the trough.

更には、板バネを用いているため、トラフ用蓋固定部材の装着時にはトラフ用蓋固定部材をトラフ用蓋の上方にセットした後に天板を比較的小さな力で押せば、板バネ部がトラフ本体及びトラフ用蓋の側壁部等に押されて圧縮され、トラフ本体にトラフ用固定部材を容易に嵌めることができる。また、トラフ本体の係止部を通過して板バネ部の形状が元に戻った後は、板バネ部がトラフ本体の係止部に引っかかって、引き抜こうとしても引き抜くことができずトラフ本体からトラフ用蓋を簡単には外せない。 Furthermore, since a leaf spring is used, when the trough lid fixing member is mounted, if the top plate is pressed with a relatively small force after the trough lid fixing member is set above the trough lid, the leaf spring portion will become the trough. The trough fixing member can be easily fitted into the trough body by being compressed by being pressed by the side walls of the main body and the trough lid. In addition, after the leaf spring part has returned to its original shape after passing through the locking part of the trough body, the leaf spring part is caught by the locking part of the trough body and cannot be pulled out even if it is pulled out. The trough lid cannot be easily removed.

更には、請求項１及び２の発明に用いるトラフ用蓋固定部材は、板バネ部が側板部の内側に形成され、且つ、前記天板部と前記側板部の接続部近傍にガイド孔が設けられているため、前記トラフ蓋の外側の係止部の上方に形成される空間で、操作棒等を用いることにより、ガイド孔に操作棒を挿入して操作棒を内側へ傾ければ、テコの原理によって容易に側板部が外側へ広がり、板バネ部をトラフ本体の係止部から外すことができる。その状態でトラフ用蓋固定部材を上方に引き上げて取り除けば、容易にトラフ用蓋をトラフ本体から取り外すことができる。
Furthermore, the trough lid fixing member used in the inventions of claims 1 and 2 has a leaf spring portion formed inside the side plate portion, and a guide hole provided in the vicinity of the connecting portion between the top plate portion and the side plate portion. Therefore, if the operating rod is inserted into the guide hole and tilted inward by using an operating rod in the space formed above the engaging portion outside the trough lid , By this principle, the side plate portion can easily spread outward and the leaf spring portion can be removed from the locking portion of the trough body. If the trough lid fixing member is pulled upward in this state and removed, the trough lid can be easily removed from the trough body.

また、前述のように、請求項１及び２の発明に用いるトラフ用蓋固定部材は、折り曲げ一体成形された金属板である。このようにして成るトラフ用蓋固定部材は、１枚の金属製板を折り曲げて孔開け加工するだけなので、作製が容易でコストがかからない。
In addition, as described above, the trough lid fixing member used in the inventions of claims 1 and 2 is a metal plate that is integrally formed by bending. The trough lid fixing member formed in this manner is easy to manufacture and does not cost, since it only needs to bend and punch a single metal plate.

以上のように本願請求項１及び請求項２に記載の発明によれば、トラフを壁面に寄せて配置した場合等にもトラフ本体の開口に被せたトラフ用蓋をトラフ本体に容易かつ確実に固定することができ、固定した後には取り外し方法が容易に察知されないトラフ用蓋固定部材とトラフの固定構造及びトラフ用蓋固定部材の着脱方法を提供することができる。
As described above , according to the first and second aspects of the present invention, the trough lid can be easily and reliably attached to the trough main body even when the trough is arranged close to the wall surface. It is possible to provide a trough lid fixing member and a trough fixing structure and a trough lid fixing member attaching / detaching method that can be fixed and cannot be easily detected after the fixing .

以下に本願発明のトラフ用蓋固定部材の第一の実施例を図１〜図３を用いて詳細に説明する。   The first embodiment of the trough lid fixing member of the present invention will be described below in detail with reference to FIGS.

図１は本願発明に係るトラフ１０のトラフ本体１１及びトラフ用蓋１２の一例を示す斜視図である。図１に示すように、このトラフ１０は底壁部２１と左右の側壁部２２、２２とを有し、上方が開口しているトラフ本体１１と、該トラフ本体１１の開口を塞ぐトラフ用蓋１２とからなっている。そして前記トラフ本体１１の左右の側壁部２２、２２の外面上部には係止部２３、２３が各々設けられている。   FIG. 1 is a perspective view showing an example of a trough body 11 and a trough lid 12 of a trough 10 according to the present invention. As shown in FIG. 1, the trough 10 has a bottom wall portion 21 and left and right side wall portions 22, 22, a trough body 11 that is open at the top, and a trough lid that closes the opening of the trough body 11. It consists of twelve. Locking portions 23 and 23 are provided on the upper outer surfaces of the left and right side wall portions 22 and 22 of the trough main body 11, respectively.

図２は本発明の第一の実施形態に係るトラフ用蓋固定部材１の斜視図である。図２に示すトラフ用蓋固定部材１は、幅４２ｍｍ、厚さが１．５ｍｍの１枚のステンレス製板を折り曲げ加工したもので、天板部２と２つの側板部３とを有する断面コ字状体であり、２つの側板部３は図１に示したトラフ１０をすっぽり覆える間隔に形成されている。また、２つの側板部３の先端は内角が１５度となるように内側に折り曲げて板バネ部４を形成しており、この板バネ部４はトラフ用蓋固定部材１を図１に示したトラフ１０に装着した時にトラフ本体１１の側壁部２２に設けられた係止部２３に係止できる位置に形成されている。更に、天板部２と側板部３の接合部にはそれぞれ長さ方向１０ｍｍの天板部に３ｍｍ及び側板部に３ｍｍに亘る切り欠け状のガイド孔５が１つずつ、計２つ設けられている。   FIG. 2 is a perspective view of the trough lid fixing member 1 according to the first embodiment of the present invention. The trough lid fixing member 1 shown in FIG. 2 is formed by bending a single stainless steel plate having a width of 42 mm and a thickness of 1.5 mm, and has a cross-sectional core having a top plate portion 2 and two side plate portions 3. It is a character-like body, and the two side plate portions 3 are formed at intervals to completely cover the trough 10 shown in FIG. Further, the tips of the two side plate portions 3 are bent inward so that the inner angle is 15 degrees to form a plate spring portion 4, and the plate spring portion 4 shows the trough lid fixing member 1 shown in FIG. It is formed at a position that can be locked to a locking portion 23 provided on the side wall portion 22 of the trough body 11 when the trough 10 is mounted. Furthermore, the joint part of the top plate part 2 and the side plate part 3 is provided with a total of two guide holes 5 each having a notch shape extending 3 mm on the top plate part having a length direction of 10 mm and 3 mm on the side plate part. ing.

図１のトラフ用蓋１２を図２のトラフ用蓋固定部材１を用いてトラフ本体１１に固定させる場合には、先ず、トラフ本体１１を布設後このトラフ１１内にケーブル類（図示しない）を収納し、その開口にトラフ用蓋１２を載置する。しかる後図３に示すように、トラフ用蓋固定部材１の２つの側板部３でトラフ本体１１の２つの側壁部２２を挟むようにしてトラフ用蓋固定部材１をトラフ用蓋１２の上方から被せ、板バネ部３を圧縮させながらトラフ本体１１の側壁部２２に設けた係止部２３の下方に押し込む。板バネ部４がトラフ本体１１の側壁部２２に設けた係止部２３の下側まで入り込むと、トラフ本体１１の側壁部２２の圧縮から開放されて板バネ部４が元の形状に戻り、その後は係止部２３に係止されて引き抜けなくなる。以上のようにして、極めて容易にトラフ本体１１とトラフ用蓋１２とを固定することができる。尚、トラフ本体１１を壁面に寄せ、開口にトラフ用蓋１２を載置した状態でトラフ用蓋固定部材１を装着してみたところ、幅方向のスペースが無くても問題なく装着できた。 When the trough lid 12 of FIG. 1 is fixed to the trough body 11 using the trough lid fixing member 1 of FIG. 2, first, the trough body 11 is laid and then cables (not shown) are placed in the trough 11. The trough lid 12 is placed in the opening. Thereafter, as shown in FIG. 3, the trough lid fixing member 1 is covered from above the trough lid 12 so that the two side plates 3 of the trough lid fixing member 1 sandwich the two side wall portions 22 of the trough body 11. The leaf spring portion 3 is compressed and pushed below a locking portion 23 provided on the side wall portion 22 of the trough body 11. When the leaf spring portion 4 enters to the lower side of the locking portion 23 provided on the side wall portion 22 of the trough body 11, the leaf spring portion 4 returns to its original shape by being released from compression of the side wall portion 22 of the trough body 11. After that, it is locked by the locking part 23 and cannot be pulled out. As described above, the trough body 11 and the trough lid 12 can be fixed very easily. In addition, when the trough main body 11 was brought close to the wall surface and the trough lid fixing member 1 was mounted in a state where the trough lid 12 was placed in the opening, the trough main body 11 was mounted without any problem even if there was no space in the width direction.

一方、図３に示すようなトラフ本体１１とトラフ用蓋１２とをトラフ用蓋固定部材１にて固定した状態からトラフ用蓋固定部材１及びトラフ用蓋１２を取り外す方法について図４を用いて説明する。トラフ用蓋固定部材１を取り外す場合には、天板部２と側板部３との接合部に設けられたガイド孔５に、例えばマイナスドライバを挿入する。図４に示したトラフ用蓋固定部材１の場合は、２つの側板部３の接合部にそれぞれ１つずつガイド孔５が設けられているので、２本のマイナスドライバを用いる。マイナスドライバをガイド孔５に挿入したら、２本のマイナスドライバを互いの上方が近づくようにして内側に傾け、マイナスドライバの先端をトラフ用蓋固定部材１の側板部３の内側に当接させる。更にマイナスドライバを内側に傾けると、各ガイド孔５の天板部２の内側エッジ部６にも当接する。この状態から更にマイナスドライバを内側に傾けると、エッジ部６が支点となって、テコの原理により容易にトラフ用蓋固定部材１の側板部３が外側に広がる。
トラフ用蓋固定部材１の側板部３を外側に広げることにより、板バネ部４がトラフ本体１０の側壁部２２に設けられた係止部２３から外れたら、そのままトラフ用蓋固定部材１を上方に持ち上げればトラフ用蓋固定部材１がトラフ本体１１から外れる。すなわち、トラフ用蓋１２をトラフ本体１１から取り外すことができる。 On the other hand, a method of removing the trough lid fixing member 1 and the trough lid 12 from the state where the trough body 11 and the trough lid 12 are fixed by the trough lid fixing member 1 as shown in FIG. explain. When removing the trough lid fixing member 1, for example, a minus driver is inserted into the guide hole 5 provided in the joint portion between the top plate portion 2 and the side plate portion 3. In the case of the trough lid fixing member 1 shown in FIG. 4, one guide hole 5 is provided at each joint portion of the two side plate portions 3, and thus two minus drivers are used. When the minus driver is inserted into the guide hole 5, the two minus drivers are tilted inward so that their upper sides approach each other, and the tip of the minus driver is brought into contact with the inside of the side plate portion 3 of the trough lid fixing member 1. When the minus driver is further tilted inward, it comes into contact with the inner edge portion 6 of the top plate portion 2 of each guide hole 5. When the minus driver is further tilted inward from this state, the edge portion 6 serves as a fulcrum, and the side plate portion 3 of the trough lid fixing member 1 easily spreads outward due to the lever principle.
When the leaf spring portion 4 is disengaged from the engaging portion 23 provided on the side wall portion 22 of the trough body 10 by spreading the side plate portion 3 of the trough lid fixing member 1 outward, the trough lid fixing member 1 is moved upward as it is. The trough lid fixing member 1 is detached from the trough main body 11 when lifted up. That is, the trough lid 12 can be removed from the trough body 11.
