Description

本発明は、建物の壁面に沿って布設される配線・配管材の布設経路における曲がり部や交差部等に配設される、配線・配管材を内部に収容して保護する配線・配管材の保護カバーに関するものである。   The present invention relates to a wiring / piping material that is disposed at a bent portion or an intersection in a wiring path of wiring / piping material laid along a wall surface of a building and protects the wiring / piping material contained therein. It relates to a protective cover.

従来より、建物の壁面に沿って配線・配管材が布設される場合は、この配線・配管材を内部に収容して保護すべくその外側に保護ダクトやモールが壁面に沿って配設される。保護ダクト等は、一般には剛体状に形成され、例えば、樋状や板状のベース部材とカバー部材との２分割体で構成され、配線・配管材が壁面に沿って布設される前または布設された後に、ベース部材が壁面に固定され、このベース部材上に配線・配管材が配置された状態でカバー部材が上方から嵌合されるなどの手段によって前記ベース部材に取付けられる。保護ダクト等は建物の壁面周辺の状況、配線・配管材の布設経路の状況などに応じて、直線状のものを基本に、これに直角に屈曲したエルボ状のものが組み合わされて配設されている。   Conventionally, when wiring / piping materials are laid along the wall surface of a building, a protective duct or a mall is arranged along the wall surface to accommodate and protect the wiring / piping material inside. . The protective duct or the like is generally formed in a rigid body, for example, composed of a two-part body of a bowl-like or plate-like base member and a cover member, and before or after the wiring / pipe material is laid along the wall surface. Then, the base member is fixed to the wall surface, and the cover member is attached to the base member by means such as fitting the cover member from above with the wiring / pipe material disposed on the base member. Protective ducts, etc., are basically straight and combined with elbows that are bent at right angles according to the situation around the wall of the building and the condition of the wiring and piping materials. ing.

ところが、施工面が複雑な凹凸や曲面となっている箇所、配線・配管材の布設経路が交差する箇所や長さ方向の位置合わせが必要な箇所などでは、前記直線状の保護ダクトとエルボ状の保護ダクトとの組み合わせのみでこれらの箇所に対応して配設し、配線・配管材を覆って保護することは一般に困難である。   However, in places where the construction surface is complex irregularities or curved surfaces, where wiring / piping material installation paths intersect or where longitudinal alignment is required, etc., the linear protective duct and elbow In general, it is difficult to cover and protect the wiring / pipe material by arranging them corresponding to these parts only in combination with the protective duct.

そこで、このような箇所に対しては、屈曲自在な蛇腹状の保護カバーが使用されている。この保護カバーは、全体を任意の曲率で湾曲させたり、捩ったり、長手方向に伸縮させるなどして、任意の曲がり部や経路の交差部等の形態に対応して経路途中に組み込むことができ、これらの箇所における配線・配管材を保護することができる。蛇腹状の保護カバーとしては、例えば、特開平１０−６８５３６公報、特開２００１−８２６７８公報等に記載されたものが知られている。   Therefore, a flexible bellows-like protective cover is used for such a portion. This protective cover can be incorporated in the middle of the route corresponding to the shape of any bend or route intersection, etc. by curving, twisting, extending or contracting in the longitudinal direction as a whole. It is possible to protect the wiring and piping materials at these locations. As the bellows-shaped protective cover, for example, those described in JP-A-10-68536 and JP-A-2001-82678 are known.

しかし、前記蛇腹状の保護カバーは、一般に比較的短かいため、蛇腹部を伸張させても、曲がり部や交差部等が長い距離に形成されている箇所には対応することができなかった。なお、これらの曲がり部や交差部等の箇所の長さに対応して全長が異なる複数種類の保護カバーを備えることはコスト的に不経済である。   However, since the bellows-like protective cover is generally relatively short, even if the bellows portion is extended, it cannot cope with a portion where a bent portion or a crossing portion is formed at a long distance. In addition, it is uneconomical in terms of cost to provide a plurality of types of protective covers having different overall lengths corresponding to the lengths of such bent portions and intersections.

そのようなことから、前記不具合を解消する保護カバーとして、特開２００５−６４７３公報に記載の可撓性配線ダクトが提案されている。
図９は、前記特開２００５−６４７３公報に記載の可撓性配線ダクトを示し、(a)はその斜視図、(b)は２個の可撓性配線ダクトを連結したものを示す断面図である。図９(a)において、可撓性配線ダクト５１は、蛇腹溝５３が軸線方向に交互に形成された蛇腹構造の可撓性配線ダクト本体５２の一端と他端に他の配線ダクトの端部に内挿または外挿される剛性を有した配線ダクト用差し口５４が連設されているとともに、該一端の配線ダクト用差し口５４と可撓性配線ダクト本体５２との間に剛性を有する短縮兼延長用差し口５５が連設されている。更に、短縮兼延長用差し口５５は内面から内方に向け可撓性配線ダクト本体５２の蛇腹溝５３に係合する蛇腹溝係合部５６が突設されており、加えて、その両側端には、それぞれ第一切断用溝５７及び第二切断用溝５８が設けられている。 For this reason, a flexible wiring duct described in Japanese Patent Application Laid-Open No. 2005-6473 has been proposed as a protective cover for solving the above-described problems.
FIG. 9 shows the flexible wiring duct described in Japanese Patent Laid-Open No. 2005-6473, (a) is a perspective view thereof, and (b) is a sectional view showing two flexible wiring ducts connected to each other. It is. In FIG. 9A, a flexible wiring duct 51 includes an end portion of another wiring duct at one end and the other end of a flexible wiring duct main body 52 having a bellows structure in which bellows grooves 53 are alternately formed in the axial direction. The wiring duct insertion port 54 having rigidity to be inserted into or inserted into the cable is connected to the cable duct, and the rigidity is shortened between the wiring duct insertion port 54 at one end and the flexible wiring duct main body 52. A cum extension slot 55 is provided continuously. Further, the shortening / extension insertion port 55 is provided with a bellows groove engaging portion 56 projecting from the inner surface toward the inward to the bellows groove 53 of the flexible wiring duct main body 52, and in addition, both side ends thereof. Are provided with a first cutting groove 57 and a second cutting groove 58, respectively.

この可撓性配線ダクト５１は、第二切断用溝５８を付した位置で配線ダクト用差し口５４を切断除去して可撓性配線ダクト本体５２の端部に短縮兼延長用差し口５５を残留させ、その一方、他の同一構造の可撓性配線ダクト５１の第一切断用溝５７から配線ダクト用差し口５４及び短縮兼延長用差し口５５を一体に切り離して除去する。しかる後、該他の可撓性配線ダクト５１の可撓性配線ダクト本体５２の端部に、前記残留した短縮兼延長用差し口５５を外挿し、蛇腹溝係合部５６を蛇腹溝５３に係合させる。これにより、２本の可撓性配線ダクト５１が相互に連結され、延長された可撓性配管ダクトが完成する。この可撓性配管ダクト５１を使用すれば、別途に延長用の保護カバーを用意することなく、第一切断用溝５７及び第二切断用溝５８で切断して相互に連結し延長することにより、曲がり部や交差部等が長くなっている経路にも対応して取付けることができ、配線・配管材を保護できる。
特開平１０−６８５３６公報 特開２００１−８２６７８公報 特開２００５−６４７３公報 This flexible wiring duct 51 cuts and removes the wiring duct insertion port 54 at the position where the second cutting groove 58 is attached, and the shortening and extension insertion port 55 is provided at the end of the flexible wiring duct main body 52. On the other hand, the wiring duct insertion port 54 and the shortening / extension insertion port 55 are integrally separated and removed from the first cutting groove 57 of another flexible wiring duct 51 having the same structure. Thereafter, the remaining shortening / extension slot 55 is extrapolated to the end of the flexible wiring duct body 52 of the other flexible wiring duct 51, and the bellows groove engaging portion 56 is inserted into the bellows groove 53. Engage. Thereby, the two flexible wiring ducts 51 are connected to each other, and an extended flexible piping duct is completed. If this flexible piping duct 51 is used, it is possible to cut the first cutting groove 57 and the second cutting groove 58 and connect and extend them without using a separate protective cover for extension. In addition, it can be attached corresponding to the route where the bent part and the intersection part are long, and the wiring and piping material can be protected.
JP-A-10-68536 JP 2001-82678 A JP 2005-6473 A

ところで、布設経路における曲がり部や交差部等の箇所に配設された前記可撓性配線ダクト５１等の保護カバーは、強制的な力によって全体的に曲げられたり部分的に屈曲し或いは捩られた状態にあるから、常に元の安定した直線状態に復帰しようとする力が生じている。このため、保護カバー相互の連結部が湾曲したり屈曲している箇所に位置しているときには、前記復元力が生じている状態において更に何らかの衝撃や外力等が加わったりした拍子に保護カバー相互の連結が解除されてしまわないよう連結部の連結強度を高めておくことが必要である。   By the way, the protective cover such as the flexible wiring duct 51 and the like disposed at a bent portion or an intersection portion in the laying path is bent entirely or partially bent or twisted by a forcible force. Therefore, there is always a force to return to the original stable linear state. For this reason, when the connecting part of the protective covers is located at a curved or bent portion, the protective covers can be connected to the time signature in which some impact or external force is further applied in the state where the restoring force is generated. It is necessary to increase the connection strength of the connecting portion so that the connection is not released.

しかし、前記特開２００５−６４７３公報に記載の可撓性配線ダクト５１は、連結される一の可撓性配線ダクト５１の端部である短縮兼延長用差し口５５は剛性を有するものの、この短縮兼延長用差し口５５に内挿される他の可撓性配線ダクト５１の端部は、その短縮兼延長用差し口５５の第一切断溝５７で切断されて形成されており、実質的に、蛇腹構造の可撓性配線ダクト本体５２の端部によって形成されているために、柔軟で屈曲変形或いは捩れ変形し易く、また長手方向に伸縮する構造となっているなど形状が変化し易いものとなっている。したがって、可撓性配管ダクト５１は、相互間の連結強度が小さく、復元力が生じている状態において、引張りや外部物体の接触が加わったりした拍子に連結が外れたり、長期間に徐々に連結が緩んできて外れたりして、可撓性配線ダクト本体５２の端部が短縮兼延長用差し口５５から抜脱してしまう虞があった。   However, in the flexible wiring duct 51 described in the above-mentioned Japanese Patent Application Laid-Open No. 2005-6473, although the shortening / extension insertion port 55 which is an end portion of one flexible wiring duct 51 to be connected has rigidity, The end portion of the other flexible wiring duct 51 inserted into the shortening / extension insertion slot 55 is formed by being cut by the first cutting groove 57 of the shortening / extension insertion slot 55. Since it is formed by the end portion of the flexible wiring duct main body 52 having a bellows structure, it is flexible, easily deformed by bending or twisting, and has a structure that expands and contracts in the longitudinal direction, so that its shape is easily changed. It has become. Accordingly, the flexible piping duct 51 is disconnected from the time signature that has been pulled or contacted by an external object or is gradually connected over a long period of time when the connection strength between the flexible piping ducts 51 is small and a restoring force is generated. As a result, the end of the flexible wiring duct main body 52 may be detached from the shortening / extension insertion port 55.

そこで、本発明は、相互に連結して延長することができ、かつ、その連結強度を大きくして連結が解除されるのを確実に防止することができ、もって、距離の長い曲がり部や交差部等の経路途中にも安定した状態で配設できる配線・配管材の保護カバーの提供を課題とするものである。   Therefore, the present invention can be connected to each other and extended, and the connection strength can be increased to reliably prevent the connection from being released. It is an object of the present invention to provide a protective cover for wiring / piping material that can be disposed in a stable state in the middle of a route such as a section.

請求項１の配線・配管材の保護カバーは、建物の壁面に沿って配設された配線・配管材を内部に収容して保護するものであって、周壁が蛇腹状に形成されて屈曲自在なカバー本体と、前記カバー本体の両端に設けられ、前記配線・配管材を内部に収容して保護する保護ダクトの端部に内挿されて接続される内挿部を有する屈曲性を有しない接続口とを備えている。そして、一端の前記接続口は、長手方向に直交して切断されることにより被連結口が形成され、他端の前記接続口は、その内挿部に、別の前記保護カバーにおける一端の接続口の被連結口に内挿されて連結される連結口を備えている。   The wiring / piping material protective cover according to claim 1 accommodates and protects the wiring / piping material disposed along the wall surface of the building, and the peripheral wall is formed in a bellows shape so that it can be bent freely. A flexible cover body and an insertion part that is provided at both ends of the cover body and is inserted into and connected to the end of a protective duct that houses and protects the wiring / piping material. And a connection port. The connection port at one end is cut perpendicularly to the longitudinal direction to form a connection port, and the connection port at the other end is connected to one end of another protective cover at the insertion portion. A connecting port is provided which is inserted into and connected to the connected port of the mouth.

この配線・配管材の保護カバーは、配線・配管材の布設経路のうち、曲がり部や交差部等の屈曲或いは湾曲する箇所に配設され、既存の保護ダクト間に組み込まれる。即ち、配線・配管材は、主に既存の保護ダクトによって保護され、この保護ダクトのみで保護しきれない曲がり部や交差部等の経路途中においては、本発明の保護カバーによって保護される。ここで、前記保護ダクトは、本発明の保護カバーと同様に、配線・配管材を内部に収容して保護する部材であるが、一般に全体が剛体で形成され、直線状の形態を基本とし、これにエルボ状などの形態が組み合わされて布設経路を形成する既存の保護部材であり、モールなどの保護部材も含まれる。   The protective cover for the wiring / piping material is disposed in a bent or curved portion of the wiring / piping material laying path, such as a bent portion or an intersection, and is installed between existing protective ducts. That is, the wiring / pipe material is mainly protected by an existing protective duct, and is protected by the protective cover of the present invention in the middle of a route such as a bent portion or an intersection that cannot be protected only by this protective duct. Here, like the protective cover of the present invention, the protective duct is a member that accommodates and protects the wiring / piping material inside, but is generally formed of a rigid body as a whole, based on a linear form, This is an existing protective member that forms an laying path by combining an elbow-like form with this, and includes a protective member such as a molding.

前記保護カバーのカバー本体は、周壁が蛇腹状に形成されて屈曲自在であり、更に捩ったり、長手方向に多少伸縮させるなどして変形させることができる。なお、カバー本体は、筒体等で形成されるが、必ずしもこれに限定されるものではない。
前記カバー本体の両端には、既存の保護ダクトの端部に接続可能な接続口が設けられており、この接続口は、長手方向に延設され保護ダクトの端部に内挿される内挿部を備えている。接続口は、保護ダクトの端部への接続に用いられる部分全体が該当し、蛇腹状に形成されたカバー本体と異なって、全体が前記カバー本体よりも屈曲性を有せず、形状が安定し、変形し難いものとなっている。但し、接続口は、保護カバー相互を連結するに際し、弾性的に係止させ得る程度に変形させることは可能である。前記接続口における内挿部は、保護ダクトに安定して接続できる長さに形成されている。
前記保護カバーは、合成樹脂材を使用して一体に形成することができる。一体に形成しても、形状を異ならせることによってカバー本体と接続口との性状を前述のように異ならせることができる。即ち、カバー本体は周壁が蛇腹状に形成され、これによって屈曲性、柔軟性を有するのに対し、接続口は周壁が平面状の筒体などに形成され、軟質性の合成樹脂材で形成されていても、保護カバー相互を連結させた状態において形状を一定に保持し得る程度の剛性を有する。なお、カバー本体と接続口とは別体で形成することを妨げるものではない。 The cover body of the protective cover has a peripheral wall formed in an accordion shape and can be bent, and can be further deformed by twisting or slightly expanding and contracting in the longitudinal direction. In addition, although a cover main body is formed with a cylinder etc., it is not necessarily limited to this.
At both ends of the cover body, a connection port that can be connected to an end portion of an existing protection duct is provided, and this connection port extends in the longitudinal direction and is inserted into the end portion of the protection duct. It has. The connection port corresponds to the entire part used for connection to the end of the protective duct. Unlike the cover body formed in a bellows shape, the whole has less flexibility than the cover body, and the shape is stable. However, it is difficult to deform. However, the connection port can be deformed to such an extent that it can be elastically locked when the protective covers are connected to each other. The insertion part in the connection port is formed to a length that can be stably connected to the protective duct.
The protective cover can be integrally formed using a synthetic resin material. Even if it forms integrally, the property of a cover main body and a connection port can be varied as mentioned above by varying a shape. That is, the peripheral wall of the cover body is formed in a bellows shape, thereby having flexibility and flexibility, whereas the connection port is formed in a cylindrical body having a flat peripheral wall and formed of a soft synthetic resin material. Even when the protective covers are connected to each other, they have such a rigidity that the shape can be kept constant. Note that the cover body and the connection port are not prevented from being formed separately.

一端の前記接続口は、長手方向に直交して切断されることにより被連結口が形成されるようになっている。この被連結口は、保護カバー相互を連結して延長するために、別の保護カバーの端部が連結される部分である。切断箇所は内挿部以外の接続口のいずれであってもよいが、内挿部との境界部で切断すると、被連結口を形成し易い。   The connection port at one end is cut perpendicular to the longitudinal direction to form a connection port. This connected port is a portion to which the end of another protective cover is connected in order to connect and extend the protective covers. The cut portion may be any of the connection ports other than the insertion portion, but if the cut portion is cut at the boundary portion with the insertion portion, the connected port is easily formed.

一方、他端の前記接続口は、その内挿部に、別の前記保護カバーにおける一端の接続口の被連結口に内挿されて連結される連結口を備えている。前記連結口は、内挿部の先端開口そのもので形成してもよいが、内挿部の長手方向の中間部で請求項３に記載のように長手方向と直交する方向に切断し、その切断部に形成するのが好ましい。内挿部を長手方向の途中で切断することなくその先端開口に連結口を形成した場合、接続口が長くなるとともに別の保護カバーにおける一端の接続口の被連結口内への内挿部の内挿長さが大きくなり過ぎて、屈曲性を有しない直線状の連結部が長くなり、相互に連結して延長したときの保護カバー全体における中間部の屈曲困難な部分が長くなり、曲がり部や交差部等に対応して円滑に屈曲させることが困難になるからである。但し、切断前の内挿部が短いものであっても、既存の保護ダクトに安定して接続できる場合はこの限りでなく、他端の接続口の連結口は、内挿部の途中で切断することなく、前述のように、内挿部の先端開口そのもので形成してもよい。   On the other hand, the connection port at the other end includes a connection port that is inserted and connected to the connection port of the connection port at one end of the other protective cover at the insertion portion. The connecting port may be formed by the tip opening itself of the insertion part, but cut in a direction perpendicular to the longitudinal direction as in claim 3 at the middle part of the longitudinal direction of the insertion part, and the cutting It is preferable to form in a part. When the connecting port is formed at the tip opening without cutting the inserted part in the longitudinal direction, the connecting port becomes long and the inside of the inserted part into the connected port of the connecting port at one end of another protective cover When the insertion length becomes too long, the straight connection part without flexibility becomes long, the part of the protective cover that is difficult to bend in the whole protective cover when it is connected and extended, the bending part and This is because it becomes difficult to bend smoothly corresponding to the intersection or the like. However, even if the insertion part before cutting is short, this is not the case when it can be stably connected to the existing protective duct, and the connecting port of the other connection port is cut in the middle of the insertion part. Instead, as described above, the distal end opening itself of the insertion portion may be formed.

このように構成された配線・配管材の保護カバーは、１種類で、曲がり部や交差部等において屈曲或いは湾曲する部分が通常の長さである箇所の他、屈曲或いは湾曲する部分が長い箇所にも対応して配設することができる。屈曲或いは湾曲する部分が長い箇所の場合は、相互を連結して延長して使用する。そして、連結したときは、一端の接続口及び他端の接続口がいずれも屈曲性を有しないので、連結強度が大きい。ここで、仮に、両端の接続口の少なくとも一方が屈曲自在な蛇腹状に形成されている場合は、端部が柔軟で変形し易いため、屈曲の復元力や物体の接触等による外力の作用などによって保護カバー相互の連結が解除され易く、接続口が抜け外れてしまうことがある。しかし、本願発明の保護カバーは、前述のように、両接続口とも屈曲性を有せず、連結強度が大きいため、そのような不具合を生ぜず、安定した連結状態が得られる。   The wiring / piping material protective cover configured in this way is of one type, where the bent or curved part of the bent or intersecting part has a normal length, and where the bent or curved part is long Can also be arranged correspondingly. In the case where the bent or curved portion is a long portion, the portions are connected and extended for use. And when connected, since the connection port at one end and the connection port at the other end do not have flexibility, the connection strength is high. Here, if at least one of the connection ports at both ends is formed in a bendable bellows shape, the end portion is flexible and easily deformed. As a result, the mutual connection between the protective covers is easily released, and the connection port may come off. However, as described above, the protective cover of the present invention does not have flexibility at both connection ports and has high connection strength, so that such a problem does not occur and a stable connection state is obtained.

請求項２の配線・配管材の保護カバーは、一端の接続口の被連結口が、接続口における内挿部との境界部で長手方向に直交して切断されることにより形成されるものである。前記境界部で切断することにより被連結口を形成するのは、以下の点で都合がよいからである。即ち、この境界部で切断すれば、切断によって形成される被連結口の開口と、この被連結口に内挿されて連結される他端の接続口の連結口における外壁との形状が近似し、形状的に保護カバー相互の連結に適するからである。加えて、内挿部は、既存の保護ダクトの端部に内挿されるものであり、接続口における内挿部以外の部分より断面積が小さいため、内挿部との境界部には段部が生じている。そこで、このような形状となっている接続口をこの境界部で切断すれば、切断面に生じる開口には、その周縁から内挿部の肉厚分だけ内方に突出する突縁が形成されることとなり、境界部で切断するだけで請求項５に記載のような係止突縁が形成され、この係止突縁は保護カバー相互の連結の解除を防止する解除防止部として作用するからである。なお、接続口において内挿部との境界部の周壁にこれに沿って切断溝を形成しておくと、カッター等の工具で切断し易い。   The protective cover for the wiring / piping material according to claim 2 is formed by cutting the connection port of the connection port at one end perpendicularly to the longitudinal direction at the boundary with the insertion portion in the connection port. is there. The reason why the connection port is formed by cutting at the boundary is that it is convenient in the following points. That is, if the boundary is cut, the shape of the opening of the connected port formed by cutting and the outer wall of the connecting port of the other connecting port inserted and connected to the connected port are approximated. This is because the shape is suitable for connecting the protective covers. In addition, the insertion part is inserted into the end of the existing protective duct and has a step area at the boundary with the insertion part because the cross-sectional area is smaller than the part other than the insertion part in the connection port. Has occurred. Therefore, if the connection port having such a shape is cut at this boundary portion, a protrusion that protrudes inward from the peripheral edge by the thickness of the insertion portion is formed in the opening generated in the cut surface. Thus, the locking protrusion as described in claim 5 is formed only by cutting at the boundary portion, and the locking protrusion acts as a release preventing portion that prevents the mutual connection of the protective covers. It is. In addition, if a cutting groove is formed along the peripheral wall of the boundary portion with the insertion portion at the connection port, it is easy to cut with a tool such as a cutter.

請求項３の配線・配管材の保護カバーは、他端の接続口の連結口が、内挿部の長手方向の中間部において該内挿部が長手方向に直交して切断されることにより形成されるものである。ここで、内挿部の長手方向とは、既存の保護ダクトの端部への挿入方向を意味する。また、内挿部の中間部とは、内挿部の先端部と境界部との間の部分を意味する。内挿部の長手方向の中間部における切断位置は、切断後の内挿部を別の保護カバーの一端の接続口に連結したときの連結の安定性、及び相互に連結して延長した保護カバー全体の、曲がり部や交差部等の形態に対応した屈曲性、湾曲性等を考慮して設定する。なお、請求項２と同様に、接続口において内挿部との境界部の周壁にこれに沿って切断溝を形成しておくと、カッター等の工具で切断し易い。   The protective cover for the wiring / piping material according to claim 3 is formed by cutting the connecting port of the connecting port at the other end at a middle portion in the longitudinal direction of the inserted portion perpendicular to the longitudinal direction. It is what is done. Here, the longitudinal direction of the insertion part means the insertion direction to the end part of the existing protective duct. Moreover, the intermediate part of an insertion part means the part between the front-end | tip part of an insertion part, and a boundary part. The cutting position in the intermediate portion in the longitudinal direction of the insertion part is the stability of the connection when the insertion part after cutting is connected to the connection port at one end of another protection cover, and the protection cover that is connected and extended. It is set in consideration of the bendability, the bendability, etc. corresponding to the overall shape of the bent portion, the intersecting portion or the like. Similarly to the second aspect, if a cutting groove is formed along the peripheral wall of the boundary portion with the insertion portion at the connection port, it is easy to cut with a tool such as a cutter.

以下、本発明の実施形態の配線・配管材の保護カバーを図１乃至図８に基づいて説明する。ここで、図１乃至図３は前記配線・配管材の保護カバーを示し、図４は前記保護カバーが接続される既存の保護ダクトを、図５は保護カバー相互の連結状態を、図６及び図７は連結部等に取付けるサドルを、図８は連結された保護カバーの配設例を示す。   Hereinafter, a protective cover for wiring / piping material according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3 show a protective cover for the wiring / piping material, FIG. 4 shows an existing protective duct to which the protective cover is connected, FIG. 5 shows a connection state of the protective covers, and FIGS. FIG. 7 shows a saddle attached to a connecting portion or the like, and FIG. 8 shows an example of arrangement of the connected protective covers.

図１乃至図３において、保護カバー１は、建物の壁面に沿って配設された配線・配管材としてのケーブルＣを内部に収容して保護するものであって、ケーブルＣの布設経路途中の曲がり部や交差部等に配設されるものであり、周壁が蛇腹状に形成されて屈曲自在なカバー本体２と、その両端に設けられた接続口とを備えてなる。前記各接続口は、図４に示す、ケーブルＣを内部に収容して保護する既存の保護ダクト４１の端部に接続されるものであり、略四角筒状の基部と、この基部から長手方向に延設され前記保護ダクト４１の端部に内挿される内挿部とからなる。保護カバー１は、ＥＶＡ、ＡＢＳ等の合成樹脂により一体に形成されている。以下、各構成部について詳細に説明する。   1 to 3, the protective cover 1 accommodates and protects a cable C as a wiring / piping material disposed along the wall surface of the building, and protects the cable C in the middle of the laying path of the cable C. The cover body 2 is disposed at a bent portion, an intersection, or the like, and has a peripheral wall formed in a bellows-like shape so as to be bent, and connection ports provided at both ends thereof. Each said connection port is connected to the edge part of the existing protection duct 41 which accommodates and protects the cable C shown in FIG. 4, A base part of a substantially square cylindrical shape, and a longitudinal direction from this base part And an insertion portion that is inserted into an end portion of the protective duct 41. The protective cover 1 is integrally formed of a synthetic resin such as EVA or ABS. Hereinafter, each component will be described in detail.

まず、前記カバー本体２は、略四角筒状に形成され、周壁が蛇腹状に凹凸形成されており、環状凸部と環状凹部とが長手方向に交互に連結されている。これにより、屈曲性を有し、全体を任意の曲率で上下方向或いは左右方向に湾曲させたり、筒軸を中心に周方向に捩ったり、長手方向に多少伸縮させることもできる。   First, the cover main body 2 is formed in a substantially rectangular tube shape, the peripheral wall is formed in an accordion-like shape, and the annular convex portions and the annular concave portions are alternately connected in the longitudinal direction. Thereby, it has flexibility, and the whole can be curved in an up-down direction or a left-right direction with an arbitrary curvature, twisted in the circumferential direction around the tube axis, or slightly expanded or contracted in the longitudinal direction.

次に、カバー本体２の両端部のうちの一端の接続口１１は、カバー本体２の端部に一体に接続され、周壁がカバー本体２及び保護ダクト４１とほぼ同大であって略平面からなる四角筒状に形成された基部１２を備える。この基部１２は、底面がカバー本体２と同一高さに設定されており、カバー本体２とともに壁面に均一に当接するものとなっている。そして、基部１２は、長手方向のほぼ中間部において底面を除く周壁に外方に僅かに突出する突条からなるストッパ１４が一体に形成されており、このストッパ１４には、後述するサドル３１のフランジ３３の内面が係止し、保護カバー１が長手方向に移動するのを防止している。また、このストッパ１４が形成されていることにより基部１２の剛性が高められている。   Next, the connection port 11 at one end of both ends of the cover main body 2 is integrally connected to the end of the cover main body 2, the peripheral wall is substantially the same size as the cover main body 2 and the protective duct 41, and from a substantially flat surface. And a base 12 formed in a rectangular tube shape. The base 12 has a bottom surface set to the same height as the cover main body 2, and comes into uniform contact with the wall surface together with the cover main body 2. The base portion 12 is integrally formed with a stopper 14 made of a ridge that slightly protrudes outward on the peripheral wall except the bottom surface in a substantially intermediate portion in the longitudinal direction. The inner surface of the flange 33 is locked to prevent the protective cover 1 from moving in the longitudinal direction. Further, since the stopper 14 is formed, the rigidity of the base 12 is enhanced.

前記基部１２におけるカバー本体２と反対側の端部には、保護ダクト４１の端部に内挿される内挿部１３が長手方向に一体に延設されている。内挿部１３は、周壁１３ａが保護ダクト４１の内部形状に対応した形状に形成されており、保護ダクト４１の内方に突出する突出部や基板４４の中央に立設された仕切突片４７との干渉を避けるべく、両側壁１３ｂに逃がし部１３ｄが設けられ、底壁１３ｃの中央部に逃がし部１３ｅが設けられている。なお、保護ダクト４１の内部に前記突出部や仕切突片４７等が形成されていない場合は、当然、内挿部１３に前記逃がし部を設ける必要はなく、その場合、ケーブルＣの収容空間を大きくすることができる。そして、内挿部１３は保護ダクト４１の端部に安定した状態で接続し得る長さに形成されている。更に、内挿部１３は基部１２より断面積が小さいため、基部１２と内挿部１３との境界部１５には段差が生じ、段差部分は段部壁面１６によって閉塞されている。そして、内挿部１３における基部１２との境界部１５には凹溝によって薄肉形成された切断溝１７が周壁１３ａの全周に至って設けられている。この切断溝１７は、一端の接続口１１を長手方向に直交して切断し、後述する被連結口１８を形成するために設けられたものであり、その切断位置を示す目印としても機能する。但し、切断溝１７は、一端の接続口１１を長手方向に直交して切断することができ、切断位置を確認できれば、設けなくてもよく、また、突条に形成してもよい。   An insertion portion 13 that is inserted into the end portion of the protective duct 41 is integrally extended in the longitudinal direction at the end portion of the base portion 12 opposite to the cover main body 2. The insertion portion 13 has a peripheral wall 13 a formed in a shape corresponding to the internal shape of the protective duct 41, and a protruding portion that protrudes inward of the protective duct 41 and a partition projection piece 47 that is erected at the center of the substrate 44. In order to avoid interference with each other, a relief portion 13d is provided on both side walls 13b, and a relief portion 13e is provided in the central portion of the bottom wall 13c. In addition, when the said protrusion part, the partition protrusion piece 47, etc. are not formed in the inside of the protective duct 41, naturally, it is not necessary to provide the said escape part in the insertion part 13, In that case, the accommodation space of the cable C is provided. Can be bigger. And the insertion part 13 is formed in the length which can be connected to the edge part of the protection duct 41 in the stable state. Further, since the insertion portion 13 has a smaller cross-sectional area than the base portion 12, a step is generated at the boundary portion 15 between the base portion 12 and the insertion portion 13, and the step portion is closed by the step wall surface 16. And the cutting groove 17 formed thinly by the concave groove is provided in the boundary part 15 with the base 12 in the insertion part 13 so that the perimeter of the surrounding wall 13a may be reached. The cutting groove 17 is provided to cut the connection port 11 at one end perpendicularly to the longitudinal direction to form a connected port 18 to be described later, and also functions as a mark indicating the cutting position. However, the cutting groove 17 does not need to be provided and can be formed on the ridge as long as the connection port 11 at one end can be cut perpendicular to the longitudinal direction and the cutting position can be confirmed.

一方、カバー本体２の両端部のうちの他端の接続口２１は、カバー本体２における一端の接続口１１と反対側の端部に一体に接続され、周壁がカバー本体２及び保護ダクト４１とほぼ同大であって略平面からなる四角筒状に形成された基部２２を備える。この基部２２は、前記一端の接続口１１の基部１２と同様の形状に形成されており、底面がカバー本体２と同一高さに設定され、また、長手方向のほぼ中間部において底面を除く周壁に外方に僅かに突出する突条からなるストッパ２４が一体に形成されている。   On the other hand, the connection port 21 at the other end of the both ends of the cover body 2 is integrally connected to the end of the cover body 2 opposite to the connection port 11 at one end, and the peripheral wall is connected to the cover body 2 and the protective duct 41. A base portion 22 is provided that is substantially the same size and is formed in a rectangular tube shape that is substantially flat. The base portion 22 is formed in the same shape as the base portion 12 of the connection port 11 at the one end, the bottom surface is set to the same height as the cover body 2, and the peripheral wall excluding the bottom surface in a substantially middle portion in the longitudinal direction. Further, a stopper 24 made of a protrusion that slightly protrudes outward is integrally formed.

前記基部２２におけるカバー本体２と反対側の端部には、保護ダクト４１の端部に内挿される内挿部２３が長手方向に一体に延設されている。内挿部２３は、周壁２３ａが前記一端の接続口１１の内挿部１３と同一の断面形状を有し、保護ダクト４１の内方に突出する突出部や仕切突片４７との干渉を避けるべく、両側壁２３ｂに逃がし部２３ｄが設けられ、底壁２３ｃの中央部に逃がし部２３ｅが設けられている。なお、内挿部２３の周壁２３ａの形状は、必ずしも前記一端の接続口１１の内挿部１３と同一でなくてもよいが、同一形状に形成されていると、保護ダクト４１に接続する際、両端部のいずれか一方の接続口を任意に選択して既存の保護ダクト４１に接続することができる。また、内挿部２３は、保護ダクト４１の端部に安定した状態で接続し得る長さに形成されている。更に、基部２２と内挿部２３との境界部２５には段差が生じており、段差部分は段部壁面２６によって閉塞されている。そして、内挿部２３における長手方向の適宜位置には前記一端の接続口１１の切断溝１７と同様の切断溝２７が周壁２３ａの全周に至って設けられている。この切断溝２７は、他端の接続口２１を切断して後述する連結口２８を形成するために設けられたものである。加えて、内挿部２３において基部２２との境界部２５には、係止部２９としての所定幅の係止凹溝３０が周壁２３ａに沿って全周に設けられている。この係止凹溝３０は、保護カバー１相互を連結するに際し、一端の接続口１１の被連結口１８に形成された係止突縁２０が弾性的に係止するようになっている。   An insertion portion 23 inserted into the end portion of the protective duct 41 is integrally extended in the longitudinal direction at the end portion of the base portion 22 opposite to the cover main body 2. The insertion portion 23 has a peripheral wall 23 a having the same cross-sectional shape as the insertion portion 13 of the connection port 11 at the one end, and avoids interference with the protruding portion and the partition protruding piece 47 protruding inward of the protective duct 41. Accordingly, a relief portion 23d is provided on both side walls 23b, and a relief portion 23e is provided in the center of the bottom wall 23c. The shape of the peripheral wall 23a of the insertion portion 23 does not necessarily have to be the same as that of the insertion portion 13 of the connection port 11 at the one end. However, if it is formed in the same shape, when connecting to the protective duct 41 Any one of the connection ports at both ends can be arbitrarily selected and connected to the existing protective duct 41. Moreover, the insertion part 23 is formed in the length which can be connected to the edge part of the protection duct 41 in the stable state. Further, a step is generated at the boundary portion 25 between the base portion 22 and the insertion portion 23, and the step portion is closed by a step portion wall surface 26. And the cutting groove 27 similar to the cutting groove 17 of the said connection port 11 of the said one end is provided in the appropriate position of the longitudinal direction in the insertion part 23 so that the perimeter of the surrounding wall 23a may be reached. The cutting groove 27 is provided to cut the connection port 21 at the other end to form a connection port 28 described later. In addition, a locking recess groove 30 having a predetermined width as a locking portion 29 is provided on the entire periphery of the boundary portion 25 with the base portion 22 in the insertion portion 23 along the peripheral wall 23a. When the protective cover 1 is connected to each other, the locking groove 30 is configured so that the locking protrusion 20 formed in the connected port 18 of the connection port 11 at one end is locked elastically.

次に、前記一端の接続口１１は、切断されることによって、保護カバー１相互を連結するための被連結口１８が形成されるようになっている。この被連結口１８は、基部１２と内挿部１３との境界部１５に設けられた切断溝１７において内挿部１３が長手方向に直交して切断されることにより形成される。その切断はカッター等の工具を使用して行なうことができる。切断によって形成された被連結口１８には、その周縁に全周に至って、内挿部１３の肉厚とほぼ同一の大きさの突出量で内方に突出し、他端の接続口２１の係止部２９が係止する被係止部１９としての係止突縁２０が形成される。   Next, the connection port 11 at one end is cut to form a connection port 18 for connecting the protective covers 1 to each other. The connection port 18 is formed by cutting the insertion portion 13 perpendicularly to the longitudinal direction in a cutting groove 17 provided in the boundary portion 15 between the base portion 12 and the insertion portion 13. The cutting can be performed using a tool such as a cutter. The to-be-connected port 18 formed by cutting reaches the entire periphery of the connection port 18 and protrudes inward with a protruding amount having substantially the same size as the thickness of the insertion portion 13. A locking protrusion 20 is formed as the locked portion 19 to which the locking portion 29 is locked.

一方、前記他端の接続口２１は、切断されることによって、保護カバー１相互を連結するための連結口２８が形成されるようになっている。この連結口２８は、内挿部２３が長手方向の中間部に設けられた切断溝２７において長手方向に直交して切断されることにより形成される。この連結口２８は、別の保護カバー１における一端の接続口１１の被連結口１８に挿入され、保護カバー１相互が連結される。   On the other hand, the connection port 21 at the other end is cut to form a connection port 28 for connecting the protective covers 1 to each other. The connection port 28 is formed by cutting the insertion portion 23 perpendicularly to the longitudinal direction at a cutting groove 27 provided in the middle portion in the longitudinal direction. The connection port 28 is inserted into the connection port 18 of the connection port 11 at one end of the other protective cover 1 so that the protective covers 1 are connected to each other.

次に、前記保護カバー１が接続される保護ダクト４１は、既存のものであって内部にケーブルＣを収容して保護するものであり、図４に示すように、長手方向に沿って断面形状が一定の矩形枠状に形成されており、壁面に固定可能なベース部材４２とこのベース部材４２に弾性的に嵌着されるカバー部材４３との２分割体を組付けて成る。ベース部材４２は上方に開口する略コ字板状の一定断面に形成されており、底部の基板４４の左右両側に立設する側壁４５，４５の上端部に後述するカバー部材４３のフランジ４９と嵌合する嵌合溝４６が形成されている。また、基板４４の中央には長手方向に沿って内部を区画する仕切突片４７が立設されている。カバー部材４３はベース部材４２の上部開口を覆う覆蓋部４８が上方に緩やかに湾曲する蓋状に形成されており、幅方向の左右両端部に水平方向に屈曲してベース部材４２の嵌合溝４６内に嵌合するフランジ４９が一体に設けられている。ベース部材４２は上方からカバー部材４３を強制的に押込むことにより、両側壁４５，４５の上部が内部側に撓んで嵌合溝４６内にカバー部材４３のフランジ４９が嵌入し、これにより、カバー部材４３はベース部材４２に弾性的に着脱自在に組付けられ、安定した直状の保護ダクト４１が得られる。   Next, the protective duct 41 to which the protective cover 1 is connected is an existing one and accommodates and protects the cable C therein, and as shown in FIG. Is formed in a fixed rectangular frame shape, and is formed by assembling a two-part body of a base member 42 that can be fixed to a wall surface and a cover member 43 that is elastically fitted to the base member 42. The base member 42 is formed in a substantially U-shaped constant section that opens upward, and a flange 49 of a cover member 43, which will be described later, is provided on the upper ends of side walls 45, 45 standing on the left and right sides of the bottom substrate 44. A fitting groove 46 to be fitted is formed. In addition, a partition projection 47 that divides the interior along the longitudinal direction is provided upright in the center of the substrate 44. The cover member 43 is formed in a cover shape in which a cover portion 48 covering the upper opening of the base member 42 is gently curved upward, and is bent horizontally at both left and right end portions in the width direction so as to fit into the fitting groove of the base member 42. A flange 49 that fits within 46 is integrally provided. When the base member 42 forcibly pushes the cover member 43 from above, the upper portions of both side walls 45, 45 are bent inward, and the flange 49 of the cover member 43 is fitted into the fitting groove 46. The cover member 43 is elastically detachably attached to the base member 42, and a stable straight protective duct 41 is obtained.

次に、保護カバー１を保護ダクト４１に接続するに際して使用し、或いは、保護カバー１のカバー本体２や接続口に取着して壁面に保持させるために必要に応じて使用し、また、保護カバー１相互の連結をより強固なものとするために必要に応じて補助具として使用するサドル３１を図６に基づいて説明する。図６において、サドル３１はダクトや配管の固定等に用いる公知のものであり、金属製或いは合成樹脂製で全体が略コ字板状に形成され、コ字板状のサドル本体３２の幅方向の両側部には内方に向けて直角に屈曲する一対のフランジ３３，３３がサドル本体３２の全長に至って形成されている。また、サドル本体３２の両側壁３４の外面にはそれぞれ壁面に固定するための釘等の固定具が挿通する略円筒状の固定部３５が一体に付設されている。   Next, it is used when the protective cover 1 is connected to the protective duct 41, or is used as necessary to attach the protective cover 1 to the cover body 2 or the connection port of the protective cover 1 and hold it on the wall surface. A saddle 31 used as an auxiliary tool as necessary in order to further strengthen the connection between the covers 1 will be described with reference to FIG. In FIG. 6, a saddle 31 is a well-known one used for fixing ducts and pipes, and is made of metal or synthetic resin and is formed into a substantially U-shaped plate as a whole. A pair of flanges 33, 33 bent at right angles toward the inside are formed on both sides of the saddle body 32 so as to reach the entire length of the saddle body 32. Further, a substantially cylindrical fixing portion 35 through which a fixing tool such as a nail for fixing to the wall surface is inserted is integrally provided on the outer surface of both side walls 34 of the saddle body 32.

次に、上記のように構成された本実施形態の保護カバー１を布設経路途中の曲がり部や交差部等に配設する方法を説明する。
まず、布設経路の曲がり部や交差部における距離が比較的短いためにその箇所に１本の保護カバー１のみを配設する場合を説明する。
保護カバー１の配設に先立ち、保護ダクト４１を布設経路に沿って配設する。保護ダクト４１は主に布設経路において直線部分には前記直状の保護ダクト４１が配設され、距離の短い曲がり部には直角に折曲したエルボ状の保護ダクトが配設される。保護ダクト４１を壁面に配設するには、直状の保護ダクト４１の場合、まず、ベース部材４２の基板４４をこれに設けた図示しないねじ孔に螺子を挿通して壁面に螺着し、壁面に固定する。次いで、この基板４４上にケーブルＣを配置した後、ベース部材４２の上方開口側からカバー部材４３を押込んで取着する。エルボ状の保護ダクト４１も同様にして壁面に配設することができる。 Next, a method of disposing the protective cover 1 of the present embodiment configured as described above at a bent part or an intersection part in the middle of the laying path will be described.
First, a case where only one protective cover 1 is disposed at a bent portion or an intersecting portion of the laying path because the distance is relatively short will be described.
Prior to the provision of the protective cover 1, the protective duct 41 is disposed along the laying path. The protective duct 41 is mainly provided with the straight protective duct 41 at a straight portion in the laying path, and an elbow-shaped protective duct bent at a right angle is provided at a bent portion having a short distance. In order to arrange the protective duct 41 on the wall surface, in the case of the straight protective duct 41, first, the substrate 44 of the base member 42 is screwed into the wall surface by inserting a screw into a screw hole (not shown) provided therein, Secure to the wall. Next, after the cable C is arranged on the substrate 44, the cover member 43 is pushed in from the upper opening side of the base member 42 and attached. Similarly, the elbow-shaped protective duct 41 can be disposed on the wall surface.

保護ダクト４１を壁面Ｗに固定したら、布設経路の曲がり部や交差部に保護カバー１を配置しつつ、内部にケーブルＣを挿通し、保護カバー１のいずれか一側の接続口の内挿部を壁面に配設されている前記保護ダクト４１の端部に内挿する。このとき、保護カバー１の接続口の内挿部には、保護ダクト４１の内方に突出する突出部や仕切突片４７等との干渉を防止すべく、逃がし部が設けられているので、内挿部を支障なく保護ダクト４１の端部に内挿することができる。その後、図６に示すサドル３１等の固定具を、図７(a)に示すように、保護カバー１の接続口の内挿部と保護ダクト４１の端部とに跨って壁面に固定する。これにより、保護カバー１の接続口は、ストッパがサドル３１のフランジ３３内面に係止して保護ダクト４１から抜脱するのが防止される。以上により、保護カバー１は布設経路途中の曲がり部や交差部等に配設される。なお、その後は、この保護カバー１の他端側に次の保護ダクト４１を接続し、以下、順次、保護ダクト４１等を連結していき、布設経路全体に至って配設する。これにより、ケーブルＣは保護ダクト４１及び保護カバー１によって布設経路の全体に至って保護される。   When the protective duct 41 is fixed to the wall surface W, the cable C is inserted inside the protective cover 1 at the bent or intersecting portion of the laying path, and the insertion portion of the connection port on one side of the protective cover 1 is inserted. Is inserted into the end of the protective duct 41 provided on the wall surface. At this time, since the insertion part of the connection port of the protective cover 1 is provided with a relief part to prevent interference with the protruding part protruding inward of the protective duct 41, the partition protruding piece 47, etc. The insertion portion can be inserted into the end portion of the protective duct 41 without hindrance. Thereafter, the fixture such as the saddle 31 shown in FIG. 6 is fixed to the wall surface across the insertion portion of the connection port of the protective cover 1 and the end portion of the protective duct 41 as shown in FIG. As a result, the connection port of the protective cover 1 is prevented from being pulled out of the protective duct 41 by the stopper being locked to the inner surface of the flange 33 of the saddle 31. As described above, the protective cover 1 is disposed at a bent portion or an intersection portion in the middle of the laying path. After that, the next protective duct 41 is connected to the other end side of the protective cover 1, and the protective duct 41 and the like are sequentially connected to the entire installation route. Thus, the cable C is protected by the protective duct 41 and the protective cover 1 over the entire laying path.

次に、布設経路の曲がり部や交差部における距離が長いためにその箇所に２本の保護カバー１を連結して長尺の保護カバーを形成し、これを配設する場合を説明する。
保護カバー１の配設に先立ち、前述の曲がり部や交差部における距離が短い場合と同様にして、保護ダクト４１を布設経路に沿って配設する。 Next, a description will be given of a case where a long protective cover is formed by connecting two protective covers 1 to the portions because the distance at the bent portion or the intersecting portion of the laying path is long, and a long protective cover is formed.
Prior to the provision of the protective cover 1, the protective duct 41 is disposed along the laying path in the same manner as in the case where the distance at the bent portion or the intersection portion is short.

併せて、２本の保護カバー１を相互に連結して長尺の保護カバーを形成する。それには、いずれか一方の保護カバー１の一端の接続口１１を基部１２と内挿部１３との境界部１５に形成された切断溝１７において長手方向と直交して切断する。すると、一端の接続口１１は切断箇所において開口し、この部分に被連結口１８が形成されるとともに、その被連結口１８の周壁には、その全周に渡って内挿部１３の肉厚にほぼ相当する突出量の係止突縁２０が形成される。この係止突縁２０は被係止部１９となる。一方、この保護カバー１とは別の保護カバー１の他端の接続口２１を内挿部２３の長手方向の中間部に形成された切断溝２７において長手方向と直交して切断する。すると、他端の接続口２１は切断箇所において開口し、この部分に連結口２８が形成される。   In addition, the two protective covers 1 are connected to each other to form a long protective cover. For this purpose, the connection port 11 at one end of one of the protective covers 1 is cut at a cutting groove 17 formed at the boundary portion 15 between the base portion 12 and the insertion portion 13 at right angles to the longitudinal direction. Then, the connection port 11 at one end is opened at the cut portion, and a connected port 18 is formed at this portion, and the wall of the insertion portion 13 is formed on the peripheral wall of the connected port 18 over the entire circumference. The locking projection edge 20 is formed with a projection amount substantially corresponding to. The locking protrusion 20 becomes the locked portion 19. On the other hand, the connection port 21 at the other end of the protective cover 1 different from the protective cover 1 is cut perpendicularly to the longitudinal direction at a cutting groove 27 formed in the middle portion of the insertion portion 23 in the longitudinal direction. Then, the connection port 21 at the other end opens at the cut portion, and the connection port 28 is formed at this portion.

そこで、一方の保護カバー１の一端の接続口１１に形成された被連結口１８に、別の保護カバー１の他端の接続口２１に形成された連結口２８を挿入して、両保護カバー１を相互に連結する。このとき、被連結口１８には係止突縁２０が形成されているので、他端の接続口２１の連結口２８を強く押圧するなどして縮径させるように変形させつつ強制的に圧入する。圧入後は、一端の接続口１１の被係止部１９としての係止突縁２０が他端の接続口２１の係止部２９としての係止凹溝３０に嵌入して係止する。   Then, the connection port 28 formed in the connection port 21 at the other end of the other protective cover 1 is inserted into the connection port 18 formed at the connection port 11 at one end of the one protection cover 1, and both protection covers Connect 1 to each other. At this time, since the engagement port 18 is formed with the locking projection edge 20, the coupling port 28 of the other connection port 21 is strongly pressed, for example, and is forcedly press-fitted while being deformed to reduce the diameter. To do. After the press-fitting, the locking protrusion 20 as the locked portion 19 of the connection port 11 at one end is fitted and locked in the locking groove 30 as the locking portion 29 of the connection port 21 at the other end.

壁面の所定位置に保護ダクト４１を固定し、２本の保護カバー１を連結したら、前述の曲がり部や交差部における距離が短い場合と同様にして、布設経路の曲がり部や交差部に連結された１本の長尺の保護カバーを配置しつつ、内部にケーブルＣを挿通し、保護カバー１のいずれか一側の接続口の内挿部を壁面に配設されている前記保護ダクト４１の端部に内挿する。その後、図６に示すサドル３１等の固定具を、図７(a)に示すように、保護カバー１の接続口の内挿部と保護ダクト４１の端部とに跨って壁面に固定する。これにより、保護カバー１の接続口は、ストッパがサドル３１のフランジ３３内面に係止して保護ダクト４１から抜脱するのが防止される。また、２本の保護カバー１の連結箇所にサドル３１を固定するための壁面等が存在する場合は、図７(b)に示すように、サドル３１を一方の保護カバー１の一端の接続口１１と別の保護カバー１の他端の接続口２１とに跨って壁面に固定する。これにより、両保護カバー１の接続口は、ストッパがサドル３１のフランジ３３内面に係止し、保護ダクト４１が相互に長手方向にずれて連結が解除されるのがより確実に防止される。この場合、サドル３１の両フランジ３３の内面相互の間隔Ｌは、連結された両保護カバー１の接続口のストッパの間隔と一致するよう設定しておくと、保護カバー１が長手方向に移動せずがたつかない安定した連結状態を得ることができる。以上により、保護カバー１は布設経路途中の曲がり部や交差部等に配設される。なお、その後は、この保護カバー１の他端側に次の保護ダクト４１を接続し、以下、順次、保護ダクト４１等を連結していき、布設経路全体に至って配設する。これにより、ケーブルＣは保護ダクト４１及び保護カバー１によって布設経路の全体に至って保護される。   When the protective duct 41 is fixed at a predetermined position on the wall surface and the two protective covers 1 are connected, the protective duct 41 is connected to the bent portion or the intersecting portion of the laying path in the same manner as in the case where the distance at the bent portion or the intersecting portion is short. The protective duct 41 is arranged such that the cable C is inserted into the inside of the protective cover 41 and the insertion portion of the connection port on either side of the protective cover 1 is disposed on the wall surface while arranging one long protective cover. Interpolate at the end. Thereafter, the fixture such as the saddle 31 shown in FIG. 6 is fixed to the wall surface across the insertion portion of the connection port of the protective cover 1 and the end portion of the protective duct 41 as shown in FIG. As a result, the connection port of the protective cover 1 is prevented from being pulled out of the protective duct 41 by the stopper being locked to the inner surface of the flange 33 of the saddle 31. If there is a wall or the like for fixing the saddle 31 at the connection location of the two protective covers 1, the saddle 31 is connected to one end of one protective cover 1 as shown in FIG. 11 and the connection port 21 at the other end of the other protective cover 1. As a result, the stoppers of the connection ports of the protective covers 1 are locked to the inner surface of the flange 33 of the saddle 31 and the protective duct 41 is more reliably prevented from being disconnected due to the mutual displacement in the longitudinal direction. In this case, if the distance L between the inner surfaces of the flanges 33 of the saddle 31 is set to coincide with the distance between the stoppers of the connection ports of the two protective covers 1, the protective cover 1 is moved in the longitudinal direction. It is possible to obtain a stable connection state that does not rattle. As described above, the protective cover 1 is disposed at a bent portion or an intersection portion in the middle of the laying path. After that, the next protective duct 41 is connected to the other end side of the protective cover 1, and the protective duct 41 and the like are sequentially connected to the entire installation route. As a result, the cable C is protected by the protective duct 41 and the protective cover 1 over the entire laying path.

保護カバー１相互を連結して長尺とした保護カバー１を壁面に配設する具体例としては、図８(a)に示すように、同一壁面Ｗ内において２本の直状の保護ダクト４１の間の曲率半径の大きい曲がり部に配設する例が挙げられる。また、図８(b)に示すように、壁面Ｗの突出部に他の保護ダクト４１、モール、配管等が布設されている状況において、本実施形態の長尺の保護カバー１をこれに交差するように配設する例が挙げられる。或いは、図８(c)に示すように、直交する２つの壁面Ｗに跨って各壁面Ｗに配設された直状の保護ダクト４１の間に、本実施形態の長尺の保護カバー１を捩るようにして配設する例が挙げられる。なお、これらの保護カバー１において連結部やカバー本体２の適宜位置にサドル３１を取着してもよく、その場合、保護カバー１相互の連結が解除されるのをより確実に防止することができる。   As a specific example in which the protective cover 1 that is elongated by connecting the protective covers 1 to each other is disposed on the wall surface, as shown in FIG. The example arrange | positioned in the bending part with a large curvature radius between. Further, as shown in FIG. 8 (b), in the situation where another protective duct 41, molding, piping, etc. are laid on the protruding portion of the wall surface W, the long protective cover 1 of the present embodiment intersects with this. An example of such arrangement is given. Alternatively, as shown in FIG. 8 (c), the long protective cover 1 of the present embodiment is placed between the straight protective ducts 41 disposed on each wall surface W across two orthogonal wall surfaces W. An example of twisting is provided. In these protective covers 1, saddles 31 may be attached at appropriate positions of the connecting portion and the cover main body 2, and in this case, it is possible to more reliably prevent the mutual connection of the protective covers 1. it can.

次に、本実施形態の保護カバー１の作用を説明する。
保護カバー１は端部の接続口に連結口２８及び被連結口１８が形成されるようになっているから、一の保護カバー１の被連結口１８に別の保護カバー１の連結口２８を挿入することにより、相互に連結して延長することができる。その結果、相互を連結して延長された長尺の保護カバーを布設経路の曲がり部や交差部等であってその距離が長い箇所に配設することができる。それにより、１種類の保護カバー１で、曲がり部や交差部等において屈曲或いは湾曲する部分が通常の長さである箇所の他、連結して、屈曲或いは湾曲する部分が長い箇所にも対応して配設することができ、それらの箇所におけるケーブルＣを保護することができる。
また、保護カバー１は、端部の接続口に連結口２８及び被連結口２８が形成されているので、任意の数だけ相互に連結して延長することができる。このため、経路中の曲がり部や交差部等が如何に長くてもそれに対応して保護カバーを配設することができる。 Next, the operation of the protective cover 1 of the present embodiment will be described.
Since the protective cover 1 has a connecting port 28 and a connected port 18 formed at the connection port at the end, the connecting port 28 of another protective cover 1 is connected to the connected port 18 of one protective cover 1. By inserting, it can extend mutually connected. As a result, it is possible to dispose a long protective cover that is extended by connecting each other at a place where the distance is long, such as a bent portion or an intersecting portion of the laying path. As a result, one type of protective cover 1 can be used for not only a portion where the bent or curved portion is bent or curved at a normal length, but also a portion where the bent or bent portion is long. The cable C in those places can be protected.
Further, since the protective cover 1 is formed with the connecting port 28 and the connected port 28 at the connection port at the end portion, any number of the protective cover 1 can be connected and extended. For this reason, no matter how long the bent part or the intersecting part in the route is, a protective cover can be provided correspondingly.

そして、保護カバー１の両端の接続口はいずれも屈曲性を有しない剛体状に形成されている。具体的には、周壁が略平面からなる四角筒状に形成され、また、基部と内挿部との境界に段部壁面が形成され、更には、基部の周壁に沿って突条からなるストッパが設けられていることにより、剛性を有している。このため、仮に、両端の少なくとも一方が屈曲自在な蛇腹状に形成されている場合には、端部が柔軟で変形し易いため、屈曲の復元力や物体の接触等による外力の作用などによって保護カバー１相互の連結が解除され易く、接続口が抜け外れてしまうことがあるところ、本実施形態の保護カバー１はそのような不具合を生ぜず、安定した連結状態が得られ、連結が解除されてしまうのを確実に防止できる。   And the connection port of the both ends of the protective cover 1 is formed in the rigid body which does not have flexibility. Specifically, the peripheral wall is formed in a rectangular tube shape having a substantially flat surface, a stepped wall surface is formed at the boundary between the base portion and the insertion portion, and further, a stopper made of a protrusion along the peripheral wall of the base portion. By providing, it has rigidity. For this reason, if at least one of the both ends is formed in a flexible bellows shape, the end is flexible and easily deformed, so that it is protected by the bending restoring force or the action of external force due to contact with an object, etc. When the covers 1 are easily disconnected from each other and the connection port may come off, the protective cover 1 according to the present embodiment does not cause such a problem, and a stable connection state is obtained and the connection is released. Can be reliably prevented.

また、一端の接続口１１の被連結口１８は、接続口１１における内挿部１３との境界部１５で長手方向に直交して切断されることにより形成され、その切断に伴って、切断面に生じる開口には、その周縁から内挿部１３の肉厚分だけ内方に突出する突縁が形成されることとなり、境界部１５で切断するだけで被係止部１９としての係止突縁２０を形成できる。
更に、他端の接続口２１の連結口２８は、内挿部１３の長手方向の中間部において長手方向に直交して切断するだけで簡単に形成することができる。 Moreover, the to-be-connected port 18 of the connection port 11 at one end is formed by cutting perpendicularly to the longitudinal direction at the boundary 15 with the insertion portion 13 in the connection port 11, and along with the cutting, the cut surface In the opening formed in the opening, a protruding edge that protrudes inward from the peripheral edge by the thickness of the insertion portion 13 is formed, and the locking protrusion 19 as the locked portion 19 is simply cut at the boundary portion 15. An edge 20 can be formed.
Furthermore, the connection port 28 of the connection port 21 at the other end can be formed simply by cutting at a middle portion in the longitudinal direction of the insertion portion 13 perpendicular to the longitudinal direction.

加えて、一端の接続口１１の被連結口１８に被係止部１９としての係止突縁２０を備え、他端の接続口２１の連結口２８に前記被係止部１９と係止する係止部２９としての係止凹溝３０を備えているから、保護カバー１の端部相互を係止させることができる。   In addition, the connection port 18 of the connection port 11 at one end is provided with a locking protrusion 20 as the locked portion 19, and the connection port 19 of the connection port 21 at the other end is locked to the locking portion 19. Since the locking concave groove 30 as the locking portion 29 is provided, the end portions of the protective cover 1 can be locked.

そして、一端の接続口１１の被連結口１８の係止突縁２０は該被連結口１８の全周に渡って形成され、他端の接続口２１の連結口２８の係止凹溝３０は内挿部２３の周壁２３ａの全周に渡って形成されているから、より大きな連結強度が得られ、保護カバー１は互いに抜けにくく連結が解除されにくい。   The locking protrusion 20 of the connected port 18 of the connection port 11 at one end is formed over the entire circumference of the connected port 18, and the locking groove 30 of the connection port 28 of the connection port 21 of the other end is formed. Since it is formed over the entire circumference of the peripheral wall 23a of the insertion portion 23, greater connection strength is obtained, and the protective covers 1 are less likely to come out of each other and are not easily released.

ところで、上記実施形態の保護カバー１においては、一端の接続口１１の被連結口１８は、基部１２と内挿部１３との境界部１５で切断して形成しているが、必ずしもこれに限定されるものではなく、切断箇所は一端の接続口１１における他の位置に設定してもよい。
また、他端の接続口２１の連結口２８は、他端の接続口２１の内挿部２３を切断することによって形成しているが、保護カバー１相互の連結、保護ダクト４１との接続等に格別支障をきたさなければ、内挿部２３の長さを多少短く設定し、切断することなくその先端開口自体を連結口２８とすることも可能である。
更に、保護カバー１は、カバー本体２と両接続口とが一体に形成されているが、別体構造とすることを妨げるものでもない。 By the way, in the protective cover 1 of the said embodiment, although the to-be-connected port 18 of the connection port 11 of one end is cut | disconnected and formed in the boundary part 15 of the base 12 and the insertion part 13, it is not necessarily limited to this. Instead, the cut location may be set at another position in the connection port 11 at one end.
Further, the connection port 28 of the connection port 21 at the other end is formed by cutting the insertion portion 23 of the connection port 21 at the other end. However, the connection between the protection covers 1 and the connection with the protection duct 41, etc. If there is no particular problem, it is possible to set the length of the insertion portion 23 to be slightly shorter and to make the end opening itself as the connection port 28 without cutting.
Furthermore, although the protective cover 1 is integrally formed with the cover body 2 and both connection ports, it does not preclude a separate structure.

加えて、上記実施形態の保護カバー１は、一端の接続口１１の被係止部１９と他端の接続口２１の係止部２９とを係止させて、長手方向に抜け外れるのを防止しているが、その係止手段に限られるものではなく、また、他の嵌合、かしめ等の手段によって抜脱を防止してもよい。   In addition, the protective cover 1 of the above embodiment prevents the locking portion 19 of the connection port 11 at one end and the locking portion 29 of the connection port 21 at the other end from coming off in the longitudinal direction. However, it is not limited to the locking means, and the removal may be prevented by other means such as fitting and caulking.

そして、上記実施形態の保護カバー１は、カバー本体２の底面の幅方向中央に長手方向に沿って薄肉の細溝を長手方向に設け、ケーブルＣの布設施工時に、前記細溝に沿って切断して長手方向にスリットを形成することを妨げるものではない。このスリットを設けた場合は、ケーブルＣを壁面に沿って布設した後に、保護カバー１をケーブルＣの上方から被せつつ壁面に配設することができる。但し、スリットを設けると、接続口の剛性及び強度が低下するので、その点の注意が必要である。   The protective cover 1 of the above embodiment is provided with a thin thin groove in the longitudinal direction at the center in the width direction of the bottom surface of the cover body 2 in the longitudinal direction, and is cut along the narrow groove when the cable C is laid. Thus, it does not prevent the slits from being formed in the longitudinal direction. When this slit is provided, after the cable C is laid along the wall surface, the protective cover 1 can be disposed on the wall surface while covering the cable C from above. However, if a slit is provided, the rigidity and strength of the connection port are lowered, so that attention must be paid to this point.

なお、上記実施形態では、壁面に沿って布設する配線・配管材は、ケーブルＣを例示しているが、本発明の保護カバー１は、他の配線材や、電線管、冷媒管等の配管材を布設する場合にも同様に適用できることは言うまでもない。   In addition, in the said embodiment, although the wiring and piping material laid along the wall surface has illustrated the cable C, the protective cover 1 of this invention is piping, such as another wiring material, an electric wire pipe, a refrigerant pipe, etc. Needless to say, the present invention can be similarly applied to laying materials.
