Description

【０００１】
【産業上の利用分野】
本発明は、単位ケーブル保護枠体の多数個を湾曲自在に接続してなるケーブルガイドに関するものである。
【０００２】
【従来の技術】
可動部に光ファイバケーブル等を配線する時には、長さの短い単位ケーブル保護枠体を多数個連結して回動自在としたケーブルガイド内に、光ファイバケーブルを収納し配線を保護したものがある。
【０００３】
【発明が解決しようとする課題】
ところが、このようなケーブルガイドにおいて、単体のケーブルガイドでは、収納できる配線数が限られているため、収納する配線数に対応した数種類の単位ケーブル保護枠体を用意しなくてはならず、生産上コストが高くなる上、在庫管理等も大変であった。また、仕様の変更及び増設等により配線数が予定以上に増えたり、配線の太さが太くなったりした場合には単体のケーブルガイドでは、収まりきらない恐れがあった。
【０００４】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明は、上記の課題を解決するためになされた本発明は、底板部の両側に側板部を立設した単位ケーブル保護枠体の多数個を接続し回動自在としたケーブルガイドにおいて、該ケーブルガイド同士を上下方向に連結可能とすると共に、前記単位ケーブル保護枠体の側板部中央に形成したカバー取付け用の係止部に取付けた連結部材によりケーブルガイド同士を連結可能とし、さらに前記連結部材をカバーと兼用したことを特徴とするものである。また、底板部の両側に側板部を立設した単位ケーブル保護枠体の多数個を接続し回動自在としたケーブルガイドにおいて、該ケーブルガイド同士を水平方向に連結可能とすると共に、前記単位ケーブル保護枠体の側板部中央に形成したカバー取付け用の係止部に取付けた連結部材によりケーブルガイド同士を連結可能とし、さらに前記連結部材をカバーと兼用してもよい。さらに、前記連結部材をケーブルガイドの両側に取り付け上下方向に連結した連結式ケーブルガイドであって、片側の連結部材を係止部より外したとき、他方の連結部材を係止部に対して回転可能として、上側のケーブルガイドが下側のケーブルガイドに対し回動可能としたものであってもよい。
【０００５】
【発明の実施の形態】
次に、本発明の実施の形態を図面に基づき詳細に説明する。１は底板部２の両側に側板部３、３を立設した長さ約２８ｍｍ、高さ約２２ｍｍ、幅約２５ｍｍの長さの短いＵ字状の単位ケーブル保護枠体であり、前記底板部２は一方の端部側を接続差込板部２ａに形成するとともに、他方の端部側を前記接続差込板部２ａが上下に遊嵌できる間隙を確保したスリット２ｃを設けた接続受板部２ｂに形成したうえ、該接続差込板部２ａの表裏面に接続突起４ａ、４ａを突設し、接続受板部２ｂには接続孔４ｂを設けており、単位ケーブル保護枠体１の隣接する接続差込板部２ａを接続受板部２ｂのスリット２ｃに挿入して、該接続突起４ａを接続突起４ｂに嵌合している。
【０００６】
また、前記の側板部３、３は左右方向の湾曲の妨げにならないように一方の端部側の内側に隣接する単位ケーブル保護枠体１の両側板部３、３の他方の端部側が入り込むように、両側板部３、３の一方の端部側の内面と他方の端部側の外面を前記接続突起４ａ又は接続孔４ｂを中心軸とした略同一曲率半径の凹円弧面５ａと凸円弧面５ｂに形成し、湾曲時に凹円弧面５ａと凸円弧面５ｂとが相互に干渉しないように摺動するものとしている。さらに、他方の端部側の内面を外面の凸円弧面５ｂと平行な凹円弧面６ｂに、一方の端部側の外面を内面の凹円弧面５ａと平行な凸円弧面６ａに形成している。
【０００７】
このように形成した単位ケーブル保護枠体１を多数個接続することにより、単体のケーブルガイド７を構成したので、単体のケーブルガイド７は水平方向に回動可能、かつ上下方向に揺動可能なものとなる。また、前記底板部２の一方の端部側の接続差込板部２ａの両側に切欠部８を設けるとともに、接続受板部２ｂの両側に切欠部９を設け、この切欠部８、９の切欠端面同士を同一レベルとして、湾曲時に内側となる端面同士が当接して単体のケーブルガイド７が一定の曲率以下に湾曲しないように規制している。さらに、１０は両側板部３、３の中央上端に形成した蓋板１１を取り付けるための係止部でありこの蓋板１１は湾曲の障害にならないように両側板部３、３の中央のみを施蓋するものとされ、単体のケーブルガイド７上で適当間隔をおいて任意箇所に用いられる。なお、１２は底板部２の両側中央に突設した固定用の短円柱状の突起であり、該突起１２を取付具１３の固定板部１３ａに立設した軸受板部１３ｂの軸孔１３ｃに軸支させるものである。
【０００８】
以上の用に構成したケーブルガイド７同士を上下方向に連結可能とした連結式ケーブルガイド１４とするには、図１に示すように、両端に係合部１５、１５を備えた連結部材１６を下側のケーブルガイド７ｂの蓋板１１の係止部１０ａと上側のケーブルガイド７ａの蓋板１１の係止部１０ｂとに係合させ、同様の方法でケーブルガイド７ａ、７ｂの左右の前記係止部１０に適当数を係合させる。なお、連結部材１６は上下のケーブルガイド７ａ、７ｂの間隔をほぼ一定に保てる程度の個数を配置し、同一のケーブル保護枠材１の左右に係合させておくことが好ましい。
【０００９】
このように構成した連結式ケーブルガイド１４は、水平方向の回動は単体のケーブルガイド７と同様にできるほか、ある程度の上下方向の揺動も可能であり、可動部分の配線保護材として、単体のケーブルガイド７に収まりきらない場合等に用いることが最適である。また、単体のケーブルガイド７を連結部材１６で上下に接続するのみで連結式ケーブルガイド１４を構成できるため、既に設置された単体のケーブルガイド７を上下に段積みした連結式ケーブルガイドとすることも容易であり、さらに、単体のケーブルガイド７を３段重ね以上とした連結式ケーブルガイドとすることも可能である。即ち、専用の部品を必要とせず、収納ケーブル数を増やすことが可能であり、また最初から配線数の多い場合にも配線数の少ない場合と同じ部品で対応ができるため、専用のケーブルガイドを持つ必要がなく、生産上及び在庫管理上等のコスト面で有利なものとなる。また、上下段重ねの連結式ケーブルガイドは左右の幅を増やすことなく増設できるので、箱内の幅が限られた場合の増設に有効である。
【００１０】
さらに、連結部材１６の長手方向の長さと単位ケーブル保護枠体１の底板部２の幅を一致させれば、前記蓋体１１と連結部材１６とは同一の係止部１０にて係止されるため、連結部材１６と蓋体１１とを兼用することが可能であり、部品点数を削減することができる。また、連結部材１６をケーブルガイド７の両側に取り付けたものでは、ケーブルガイド７の一方の連結部材１６を外したとき、他方の連結部材１６を係止部１０に対して回動可能にしておけば、上側のケーブルガイド７ａが下側のケーブルガイド７ｂに対して回動することとなり、下側のケーブルガイド７ｂへの入線が容易となり作業性が向上する。
【００１１】
次に、単体のケーブルガイド７同士を水平方向に連結する場合について説明する。連結部材は上下段重ねの場合と同様の連結部材１６を用いて、図８に示すように、左側のケーブルガイド７ｃの係止部１０ｃと右側のケーブルガイド７ｄの係止部１０ｄとを連結し、この連結部材１６を両ケーブルガイド７の左右の前記係止部１０ｃ、１０ｄに適当数を係合させる。
【００１２】
このように構成した連結式ケーブルガイド１４は、上下方向の揺動は単体のケーブルガイド７と同様にできるほか、ある程度の水平方向の回動も可能であり、可動部分の配線保護材として、単体のケーブルガイド７に収まりきらない場合等に用いることが最適である。特に、箱内の上下方向に余裕がない場合の増設に適している。また、連結部材１６と蓋体１１とを兼用すれば、部品点数を削減することができる。
【００１３】
【発明の効果】
本発明は以上の説明によって明らかなように、底板部の両側に側板部を立設した単位ケーブル保護枠体の多数個を接続し回動自在としたケーブルガイドにおいて、該ケーブルガイド同士を上下方向、または水平方向に連結可能としたものであるから、専用の部品を必要とせず、収納ケーブル数を増やすことが可能であり、また最初から配線数の多い場合にも配線数の少ない場合と同じ部品で対応ができるため、専用のケーブルガイドを持つ必要がなく、生産上及び在庫管理上等のコスト面で有利なものとなる。さらに、連結部材を蓋材と兼用することにより、部品点数を削減することができコスト面で有利である。従って、本発明は従来の問題点を解決したものとして業界にもたらす益大なものである。

[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a short U-shaped unit cable protection frame having a length of about 28 mm, a height of about 22 mm, and a width of about 25 mm with side plate parts 3 and 3 erected on both sides of the bottom plate part 2. 2 is a connection receiving plate provided with a slit 2c in which one end portion side is formed in the connection insertion plate portion 2a and the other end side is secured with a gap in which the connection insertion plate portion 2a can be loosely fitted up and down. In addition, the connection protrusions 4a and 4a are provided on the front and back surfaces of the connection insertion plate 2a, and the connection holes 4b are provided in the connection receiving plate 2b. The adjacent connection insertion plate portion 2a is inserted into the slit 2c of the connection receiving plate portion 2b, and the connection projection 4a is fitted to the connection projection 4b.
[0006]
Further, the other side of the side plate portions 3 and 3 of the unit cable protection frame body 1 adjacent to the inner side of one end portion enters the side plate portions 3 and 3 so that the side plate portions 3 and 3 do not hinder the bending in the left-right direction. As described above, the inner surface on one end side and the outer surface on the other end side of both side plate portions 3 and 3 are convex with the concave arc surface 5a having substantially the same radius of curvature with the connection projection 4a or the connection hole 4b as the central axis. It is formed on the circular arc surface 5b, and slides so that the concave arc surface 5a and the convex arc surface 5b do not interfere with each other during bending. Further, the inner surface on the other end side is formed as a concave arc surface 6b parallel to the outer convex arc surface 5b, and the outer surface on one end side is formed as a convex arc surface 6a parallel to the inner concave arc surface 5a. Yes.
[0007]
Since a single cable guide 7 is configured by connecting a large number of unit cable protection frame bodies 1 formed in this way, the single cable guide 7 can rotate in the horizontal direction and can swing in the vertical direction. It will be a thing. Further, the notch portions 8 are provided on both sides of the connection insertion plate portion 2a on one end side of the bottom plate portion 2, and the notch portions 9 are provided on both sides of the connection receiving plate portion 2b. The notch end faces are set at the same level, and the end faces which are inside at the time of bending are in contact with each other so that the single cable guide 7 is not bent to a certain curvature or less. Further, reference numeral 10 denotes a locking portion for attaching a cover plate 11 formed at the center upper end of both side plate portions 3 and 3, and this cover plate 11 has only the center of both side plate portions 3 and 3 so as not to obstruct the bending. The lid is to be applied, and is used at an arbitrary position on the single cable guide 7 at an appropriate interval. Reference numeral 12 denotes a fixing short columnar protrusion protruding at the center of both sides of the bottom plate portion 2, and the protrusion 12 is inserted into the shaft hole 13 c of the bearing plate portion 13 b erected on the fixing plate portion 13 a of the fixture 13. It is to be pivotally supported.
[0008]
In order to make the cable guides 14 configured as described above to be connectable cable guides 14 that can be connected in the vertical direction, as shown in FIG. 1, connecting members 16 having engaging portions 15 and 15 at both ends are provided. The engaging portions 10a of the cover plate 11 of the lower cable guide 7b and the engaging portions 10b of the cover plate 11 of the upper cable guide 7a are engaged, and the left and right engagements of the cable guides 7a and 7b are performed in the same manner. An appropriate number is engaged with the stopper 10. The connecting members 16 are preferably arranged in such a number that the distance between the upper and lower cable guides 7 a, 7 b can be kept substantially constant and engaged with the left and right sides of the same cable protection frame member 1.
[0009]
The connection type cable guide 14 configured in this way can be rotated in the horizontal direction in the same manner as the single cable guide 7 and can swing to some extent in the vertical direction. It is optimal to use it when the cable guide 7 cannot fit. In addition, since the connection type cable guide 14 can be configured simply by connecting the single cable guide 7 up and down with the connection member 16, the connection type cable guide is formed by stacking the already installed single cable guides 7 vertically. In addition, it is possible to provide a connection type cable guide in which a single cable guide 7 is stacked in three or more stages. In other words, it is possible to increase the number of storage cables without the need for dedicated parts, and even when the number of wires is large from the beginning, it can be handled with the same parts as when the number of wires is small. There is no need to have it, which is advantageous in terms of production and inventory management. Further, the upper and lower stacked connection type cable guides can be added without increasing the left and right widths, which is effective when the width in the box is limited.
[0010]
Furthermore, if the length of the connecting member 16 in the longitudinal direction and the width of the bottom plate portion 2 of the unit cable protection frame 1 are matched, the lid 11 and the connecting member 16 are locked by the same locking portion 10. Therefore, the connecting member 16 and the lid body 11 can be used together, and the number of parts can be reduced. In the case where the connecting members 16 are attached to both sides of the cable guide 7, when one connecting member 16 of the cable guide 7 is removed, the other connecting member 16 can be rotated with respect to the locking portion 10. In this case, the upper cable guide 7a rotates with respect to the lower cable guide 7b, so that it is easy to enter the lower cable guide 7b and the workability is improved.
[0011]
Next, the case where the single cable guides 7 are connected in the horizontal direction will be described. As shown in FIG. 8, the connecting member 16 is the same as in the case of upper and lower stacks, and connects the locking portion 10c of the left cable guide 7c and the locking portion 10d of the right cable guide 7d. The connecting member 16 is engaged with the right and left engaging portions 10c, 10d of both cable guides 7 in an appropriate number.
[0012]
The connection type cable guide 14 configured in this way can swing in the vertical direction in the same manner as the single cable guide 7 and can also rotate to some extent in the horizontal direction. It is optimal to use it when the cable guide 7 cannot fit. It is especially suitable for expansion when there is no room in the vertical direction in the box. Further, if the connecting member 16 and the lid body 11 are also used, the number of parts can be reduced.
[0013]
【The invention's effect】
As is apparent from the above description, the present invention provides a cable guide in which a large number of unit cable protection frame bodies with side plate portions provided upright on both sides of a bottom plate portion are connected to each other to be rotatable. Or it can be connected in the horizontal direction, so there is no need for dedicated parts, and the number of cables can be increased. Also, when the number of wires is large from the beginning, it is the same as when the number of wires is small. Since it is possible to cope with parts, it is not necessary to have a dedicated cable guide, which is advantageous in terms of production and inventory management. Furthermore, by using the connecting member also as a lid, the number of parts can be reduced, which is advantageous in terms of cost. Accordingly, the present invention is a benefit large to bring the industry as having solved the conventional problems.
