Description

本発明は、両端に配線・配管材が内部に配設される波付き保護管を接続する接続部を備えた筒状の保護管接続具に関する。   The present invention relates to a tubular protective tube connector provided with a connecting portion for connecting a corrugated protective tube in which wiring and piping materials are disposed at both ends.

二重天井内や壁内の配線や配管材を保護する波付き保護管は可撓性があるので、巻き回した状態で保管でき、配管経路に沿って柔軟に屈曲させて配管することができ、配管経路に沿って配管された保護管は所定間隔毎にサドル等で壁面等に固定されていた。   The corrugated protective tube that protects the wiring and piping material in the double ceiling or wall is flexible, so it can be stored in a wound state and can be bent flexibly along the piping route. The protective pipe piped along the pipe path was fixed to the wall surface with a saddle or the like at predetermined intervals.

一方、この波付き保護管も必要に応じて接続する必要があり、そのために保護管同士を接続する保護管接続具が提案されている。   On the other hand, it is necessary to connect this corrugated protective tube as necessary, and for this purpose, a protective tube connector for connecting protective tubes to each other has been proposed.

図6(a)〜(d)は、そのような固定具や保護管接続具の内、本発明の背景技術となる保護管接続具を例示する図である。   FIGS. 6A to 6D are diagrams illustrating a protective tube connector that is a background art of the present invention, among such fixtures and protective tube connectors.

図6(a)の保護管接続具20は、特許文献1に記載されたもので、波付き保護管が挿入される受け口11が対向して設けられた筒状のもので、受け口11に挿入された保護管の外周への径方向(受け口11の内外方向)の移動により該保護管を抜け止め状態に係止する係止部13aと、この係止を解除することを可能とする解除操作部13bとからなる係止操作部13を備えている。   The protective tube connector 20 shown in FIG. 6A is described in Patent Document 1, and is a cylindrical one provided with a receiving port 11 into which a corrugated protective tube is inserted, and is inserted into the receiving port 11. A locking portion 13a that locks the protective tube in a retaining state by movement in the radial direction (inside and outside of the receiving port 11) to the outer periphery of the protective tube, and a release operation that enables the locking to be released The latching operation part 13 which consists of the part 13b is provided.

このような構成により、この保護管接続具20は、波付き保護管を単に受け口11に差し込むだけで抜け止め状態とでき、一方、保護管を抜き出したい場合には、解除操作部13bを操作することによって、簡単に抜き出すことができるものである。   With such a configuration, the protective tube connector 20 can be prevented from being detached by simply inserting the corrugated protective tube into the receiving port 11. On the other hand, when the protective tube is desired to be extracted, the release operation unit 13 b is operated. Can be easily extracted.

しかしながら、この保護管接続具20で接続された保護管を壁等に固定するには、別途、サドルなどと称される固定具で固定することが必要であった。   However, in order to fix the protective tube connected by the protective tube connector 20 to a wall or the like, it is necessary to separately fix it with a fixture called a saddle or the like.

図6(b)の保護管接続具30は、特許文献2に記載されたもので、筒状であって、その一方側に周方向勾配面を備えた勾配突起21aを多数突出させ、他方側に接続雄ネジを設けた継手本体21と、この継手本体21の勾配突起21a側に回動可能に設置され、勾配突起21aに対応した係止部22aを備えた係止操作リング22と、継手本体21の接続雄ネジにネジ係合する接続リング23とを備えている。   The protective tube connector 30 of FIG. 6 (b) is described in Patent Document 2, and has a cylindrical shape, and projects a large number of gradient protrusions 21a each having a circumferential gradient surface on one side, and the other side. A joint body 21 provided with a connection male screw, a locking operation ring 22 provided rotatably on the gradient protrusion 21a side of the joint body 21 and provided with a locking portion 22a corresponding to the gradient protrusion 21a, a joint A connection ring 23 is provided that engages with a connection male screw of the main body 21.

このような構成により、この保護管接続具30は、波付き保護管を単に係止操作リング22側に差し込むだけで抜け止め状態とでき、一方、保護管を抜き出したい場合には、係止操作リング22を周方向に回動させることで、係止部22aが勾配突起21aの周方向勾配面に規制されて外側に広がり、保護管を簡単に抜き出すことができるものである。   With such a configuration, the protective tube connector 30 can be prevented from being detached by simply inserting the corrugated protective tube into the locking operation ring 22 side. By rotating the ring 22 in the circumferential direction, the locking portion 22a is restricted by the circumferential gradient surface of the gradient projection 21a and spreads outward, so that the protective tube can be easily extracted.

しかしながら、この保護管接続具30の場合も、接続された保護管を壁等に固定するには、別途、サドルなどと称される固定具で固定することが必要であった。   However, in the case of the protective tube connector 30 as well, in order to fix the connected protective tube to a wall or the like, it is necessary to separately fix the protective tube with a fixture called a saddle or the like.

図6(c)、(d)は、特許文献3に記載された固定機能を有する保護管接続具を示すもので、(c)はその保護管接続具で保護管を接続する前の状態を示す側方図、(d)は接続後の状態を示す外観斜視図である。   FIGS. 6C and 6D show a protective tube connector having a fixing function described in Patent Document 3, and FIG. 6C shows a state before the protective tube is connected by the protective tube connector. The side view to show, (d) is the external appearance perspective view which shows the state after a connection.

この保護管接続具40は、一般に配管の固定に用いられるサドル様の形状をし、そのサドルの幅、固定される配管が伸びている方向の幅が通常のものより2倍以上に幅広になっているもので、可撓性の素材で形成され、配管の周縁に接する本体部31と、この本体部31の壁面側となり、壁面に接触し、この接続具40を壁面に固定するための固定部34とを備えている。   The protective tube connector 40 has a saddle-like shape generally used for fixing a pipe, and the width of the saddle and the direction in which the pipe to be fixed extends are more than twice as wide as a normal one. It is made of a flexible material and is in contact with the main body 31 that contacts the peripheral edge of the pipe, and the wall surface side of the main body 31, and the fixing for fixing the connecting device 40 to the wall surface. Part 34.

このような構成により、この保護管接続具40は、図6(c)に示すように、固定部34側を開口して、壁面Wに置かれた平滑保護管(外周が波付きでなく平滑で可撓性の少ない保護管)Pをその軸方向に直交する方向から包み込み、その後、図6(d)に示すように、固定部34によって、保護管接続具40を壁面に固定することができるものである。   With such a configuration, as shown in FIG. 6 (c), the protective tube connector 40 has a smooth protective tube (the outer periphery is not wavy but smooth) with an opening on the fixed portion 34 side and placed on the wall surface W. In this case, the protective tube connector 40 is wrapped from the direction orthogonal to the axial direction thereof, and then the protective tube connector 40 is fixed to the wall surface by the fixing portion 34 as shown in FIG. It can be done.

この際、本体部31は幅広であるので、この本体部31に接続すべき保護管Pを突き合わせ状態で収容することができる。つまり、この保護管接続具40によれば、保護管Pの接続と壁面Wへの固定とを同時にすることができる。   At this time, since the main body 31 is wide, the protective tube P to be connected to the main body 31 can be accommodated in a butted state. That is, according to the protective tube connector 40, the protective tube P can be connected and fixed to the wall surface W at the same time.

また、この保護管接続具40は、可撓性のない平滑保護管Pを固定することを想定し、保護管Pの軸方向の移動規制手段を特に備えることなく、代わりに、保護管Pの他端も同様に固定され軸方向の移動ができず、撓ませることもできないという条件下で、保護管Pを抜け止め不可に固定することを可能としているものであると思われる。   In addition, the protective tube connector 40 is assumed to fix the inflexible smooth protective tube P, and is not particularly provided with a movement restricting means in the axial direction of the protective tube P, but instead of the protective tube P. It seems that the other end is fixed in the same manner, cannot move in the axial direction, and cannot be bent, so that the protective tube P can be fixed so as not to come off.

しかしながら、撓ませることが可能な波付き保護管の場合には、この保護管接続具40による固定方法では、抜き出しを防止することができなかった。また、この保護管接続具40では、固定と接続とを同時に行うものであるので、接続具40を壁面等に固定した状態で、接続することはできなかった。

However, in the case of a corrugated protective tube that can be bent, the fixing method using the protective tube connector 40 cannot prevent extraction. Moreover, in this protective tube connector 40, since it fixes and connects simultaneously, it cannot connect in the state which fixed the connector 40 to the wall surface etc.

(A) is a plan view thereof, (b) is a front view thereof, (c) is a side view thereof, and (d) is a side view thereof. AA sectional drawing, (e) is an enlarged detail drawing of the elastic locking operation part of (d).

この保護管接続具5は、配線・配管材が内部に配設される波付き保護管を接続する接続部2を両端に備えた筒状のものであって、接続部2は、その外周の一側部が壁面に当接した状態で、接続すべき保護管を、その軸方向(図1(d)に両方向矢印で示した方向)の移動により受け入れる受け口1を備えている。   This protective tube connector 5 has a cylindrical shape provided at both ends with connecting portions 2 for connecting a corrugated protective tube in which wiring and piping materials are disposed. A receiving port 1 is provided for receiving the protective tube to be connected by movement in the axial direction (direction indicated by a double-headed arrow in FIG. 1 (d)) with one side portion in contact with the wall surface.

また、この保護管接続具5は、接続部2の壁面W(図1(b)、(c)に於いて二点鎖線の仮想線で示す。)への当接側以外の位置に設けられ、受け口1に挿入された保護管に対して、径方向(内外方向)への移動により、該保護管を抜け止め状態に係止し、この係止を解除することを可能とする係止操作部3を備えている。   Further, the protective tube connector 5 is provided at a position other than the abutting side to the wall surface W of the connecting portion 2 (indicated by a two-dot chain line in FIG. 1B and FIG. 1C). A locking operation that locks the protective tube inserted in the receiving port 1 in a radial direction (inside / outside direction) so that the protective tube is prevented from coming off and can be released. Part 3 is provided.

このような基本的構成において、この保護管接続具5は、接続部2の壁面Wへの当接側から壁面Wに向けて伸び出した当接面4a及び該当接面4aを壁面Wに当接させた状態でこの保護管接続具5を該壁面に釘やビスB等により固定可能とする固定孔4bを備えた固定部4が設けられていることを特徴とする。以下、より詳しく説明する。   In such a basic configuration, the protective tube connector 5 is configured such that the contact surface 4a extending from the contact side of the connection portion 2 to the wall surface W toward the wall surface W and the corresponding contact surface 4a are applied to the wall surface W. A fixing portion 4 having a fixing hole 4b for fixing the protective tube connector 5 to the wall surface with a nail, a screw B, or the like in a state of being in contact is provided. This will be described in more detail below.

受け口1の内径は、波付き保護管の外径に対応したものとなっており、保護管をそのまま受け入れ、接続することができる。この受け口1は、この例では、一個だけであるが、図3で例示するように、2個並列されてもよいし、3個以上並列されてもよい。   The inner diameter of the receiving port 1 corresponds to the outer diameter of the corrugated protective tube, and the protective tube can be received and connected as it is. In this example, there is only one receptacle 1, but as illustrated in FIG. 3, two may be arranged in parallel, or three or more may be arranged in parallel.

弾性係止操作部3の係止部3aは、図1(e)に示すように、受け口1の周壁の一部に、片持ち状態に形成された梁部3cの先端に、波付き保護管の外周の谷部に入り込むような突部3dを設けたものである。   As shown in FIG. 1 (e), the locking portion 3 a of the elastic locking operation portion 3 is provided with a corrugated protective tube at the tip of a beam portion 3 c formed in a cantilever state on a part of the peripheral wall of the receiving port 1. A protrusion 3d is provided so as to enter the trough on the outer periphery of the.

突部3dの保護管挿入側は、挿入される波付き保護管の外周の山部に接触して押されて、梁部3cをその弾性変形範囲内で撓ませ、突部3dを受け口1の外方向へ移動させるような挿入ガイド部3eとなっている。   The projection 3d is inserted into the protective tube insertion side in contact with a crest on the outer periphery of the waved protective tube to be inserted to bend the beam portion 3c within the elastic deformation range, and the projection 3d is received in the receiving port 1. The insertion guide 3e is moved outward.

突部3dの保護管挿入側の反対側は、抜き出されようとする波付き保護管の外周の山部に接触して押されても、梁部3cを撓ませるような力を発生させず、突部3dの谷部への入り込み状態を維持するような抜き出し防止部3fとなっている。   Even if the opposite side of the protrusion 3d to the protective tube insertion side is pressed in contact with the crest of the outer periphery of the corrugated protective tube to be extracted, no force is generated to bend the beam portion 3c. Thus, the extraction preventing portion 3f is maintained so as to maintain the state of the protrusion 3d entering the valley.

梁部3cの基端側の内側には、梁部3cをより撓みやすくする撓み凹部3gが設けられている。この撓み凹部3gは、梁部3cが受け口1の内側へ撓むときと、外側へ撓むときのいずれの場合にも、撓みやすくするものであるが、外側へ撓むときに、その撓みやすくする機能をより大きく発揮する。   On the inner side of the base end side of the beam portion 3c, a bending recess 3g that makes the beam portion 3c more flexible is provided. The bending recess 3g is easy to bend in both cases where the beam portion 3c is bent to the inside of the receiving port 1 and to the outside. However, when the beam 3c is bent to the outside, it is easy to bend. The function to perform is demonstrated more greatly.

解除操作部3bは、係止部3aの梁部3cの先端から基部方向へ、梁部3cに対して遠ざかるように、かつ、より長く、伸び出した梁形状となっている。   The release operation portion 3b has a beam shape extending longer and away from the beam portion 3c in the base direction from the tip of the beam portion 3c of the locking portion 3a.

したがって、この解除操作部3bを受け口1側へ手先で押圧すると、係止部3aの梁部3cの先端側を受け口1の外方向へ弾性変形範囲内で撓ませ、係止部3aの突部3dと挿入されていた波付き保護管の外周との間の係止を解除することができる。   Therefore, when the release operation portion 3b is pressed to the receiving port 1 side with the hand, the distal end side of the beam portion 3c of the locking portion 3a is bent outwardly within the elastic deformation range of the receiving port 1, and the protruding portion of the locking portion 3a The locking between 3d and the outer periphery of the corrugated protective tube that has been inserted can be released.

つまり、この弾性係止操作部3は、係止部3aが、保護管の挿入により弾性変形したのち該保護管の抜け止め状態を保持し、また、解除操作部3bの操作により、弾性変形して、該係止部3aの抜け止め状態の解除が可能となる弾性を利用したものとして構成されている。   In other words, the elastic locking operation unit 3 holds the protective tube in a state where it is prevented from coming off after the locking portion 3a is elastically deformed by insertion of the protective tube, and is elastically deformed by operation of the release operation unit 3b. Thus, it is configured to use elasticity that enables the locking portion 3a to be released from the retaining state.

固定部4の当接面4aは、接続部2つまり保護管接続具5を、壁面W、つまり、固定対象面に接触させるものであるが、この当接面4aと接続部2の外周面との関係は、この例のように双方の面に段差のないものでも、図5の当接面4eと接続部2Bの外周面との関係のように段差のあるものでもよい。   The abutting surface 4a of the fixing portion 4 is for bringing the connecting portion 2, that is, the protective tube connector 5, into contact with the wall surface W, that is, the surface to be fixed. This relationship may be such that there is no step on both surfaces as in this example, or there may be a step such as the relationship between the contact surface 4e in FIG. 5 and the outer peripheral surface of the connecting portion 2B.

つまり、当接面は、接続部の壁面等への当接側から壁面に向けて伸び出したもので、保護管接続具を壁面等に取り付けるのに好適なものであればよい。   In other words, the abutting surface extends from the abutting side to the wall surface or the like of the connecting portion toward the wall surface, and may be any material suitable for attaching the protective tube connector to the wall surface or the like.

固定孔4bは、釘やビスB等を挿入して、この保護管接続具5を壁面Wに固定するためのものであり、この例示のもののように、一か所に限定されるものではない。   The fixing hole 4b is for inserting a nail, a screw B or the like to fix the protective tube connector 5 to the wall surface W, and is not limited to one place as in this example. .

この固定部4は、その固定孔4bに固定ネジなどを挿入して壁面Wに、保護管接続具5を固定した場合でも、図1(b)や(c)から解るように、波付き保護管の接続、接続解除に支障となることがないものである。   Even when a fixing screw or the like is inserted into the fixing hole 4b and the protective tube connector 5 is fixed to the wall surface W, the fixing portion 4 is protected with undulations as can be seen from FIGS. 1B and 1C. It does not hinder the connection and disconnection of pipes.

接続口2が対向して設けられた保護管接続具5の両側の受け口1の内周壁の中央となる位置には、挿入した保護管の外周側に接触する中央仕切り突部5aが設けられ、保護管がそれ以上挿入されないように阻止している。この中央仕切り突部5aは、保護管に通される配線・配管材の挿通には支障のないものである。   A central partition projection 5a that contacts the outer peripheral side of the inserted protective tube is provided at the center of the inner peripheral wall of the receiving port 1 on both sides of the protective tube connector 5 provided with the connection port 2 facing the port. The protective tube is prevented from being inserted any further. The central partition projection 5a does not interfere with the insertion of the wiring / pipe material that is passed through the protective tube.

この保護管接続具5の素材は、可撓性のある合成樹脂で成形性のよいものが好適であり、例えば、ABS(アクリロニトリルブタジエンスチレン共重合体)樹脂が好適である。   The material of the protective tube connector 5 is preferably a flexible synthetic resin with good moldability, for example, an ABS (acrylonitrile butadiene styrene copolymer) resin.

特に、その素材として、難燃性ABS樹脂を用いた場合には、火災等の場合に、保護された内部の配線・配管材が火災の影響を受けるのを抑制することができる。   In particular, when a flame-retardant ABS resin is used as the material, it is possible to prevent the protected internal wiring / piping material from being affected by the fire in the event of a fire or the like.

また、このABS樹脂は、適度の機械的強度と可撓性があるので、素材の弾性によって挿入された保護管の係止、係止解除を達成する弾性係止操作部3の機能が好適に発揮されることを保証する。   Further, since this ABS resin has appropriate mechanical strength and flexibility, the function of the elastic locking operation part 3 for achieving locking and unlocking of the protective tube inserted by the elasticity of the material is suitable. Guarantee that it will be demonstrated.

これより、上記のような構成の保護管接続具5の使用方法、つまり、保護管接続具5を用いて波付き保護管SPを接続する接続方法について説明する。   Hereafter, the usage method of the protection tube connector 5 of the above structures, that is, the connection method for connecting the corrugated protection tube SP using the protection tube connector 5 will be described.

図2は、図1の保護管接続具の使用方法を説明するもので、(a)は、接続前の状態を示す正面図、(b)は、保護管接続具に波付き保護管を差し込んだ状態を示す断面図、(c)は、(b)から更に差し込まれた保護管により弾性係止操作部が撓んでいる状態を示す断面図、(d)は、挿し込みが完了した波付き保護管が保護管接続具で抜け止め防止されている状態を示す断面図、(e)は、弾性係止操作部を解除操作して、保護管を抜き出そうとしている状態を示す断面図、(f)は(a)〜(e)の過程において、保護管接続具が壁面に固定されている状態を示す側面図である。   2A and 2B illustrate a method of using the protective tube connector of FIG. 1, wherein FIG. 2A is a front view showing a state before connection, and FIG. (C) is a cross-sectional view showing a state in which the elastic locking operation portion is bent by a protective tube further inserted from (b), and (d) is a wavy state where insertion is completed. Sectional drawing which shows the state in which the protective tube is prevented from being removed by the protective tube connector, (e) is a sectional view showing the state where the elastic locking operation portion is released and the protective tube is about to be pulled out, (F) is a side view which shows the state in which the protective-tube connector is being fixed to the wall surface in the process of (a)-(e).

これより、すでに説明した部分と同じ部分には同じ符号を付して重複説明を省略する。   Accordingly, the same parts as those already described are denoted by the same reference numerals and redundant description is omitted.

まず、図2(a)に示すように、保護管接続具5と波付き保護管SPとを壁面Wに沿った状態で相互に近接させた状態とする。   First, as shown in FIG. 2A, the protection tube connector 5 and the corrugated protection tube SP are brought close to each other along the wall surface W.

なお、この場合、波付き保護管SPは可撓性があるので、波付き保護管SPの先端を図のように屈曲させて、保護管接続具5の受け口1に、その軸方向から挿入することができるので、既に設置された部分に取り替え設置しようとする際にも便利である。   In this case, since the corrugated protective tube SP is flexible, the tip of the corrugated protective tube SP is bent as shown in the figure, and inserted into the receiving port 1 of the protective tube connector 5 from its axial direction. This is also convenient when attempting to replace and install in an already installed part.

ついで、保護管SPを保護管接続具5の接続部2の受け口1に入るようにして、挿入すると、図2(b)の状態となる。   Next, when the protective tube SP is inserted so as to enter the receiving port 1 of the connecting portion 2 of the protective tube connector 5, the state shown in FIG.

図2(b)の状態では、挿入された波付き保護管SPの先端部分が、保護管接続具5の弾性係止操作部3を構成する係止部3aの突部3dに近づいた状態となっている。   In the state of FIG. 2 (b), the inserted tip portion of the corrugated protection tube SP approaches the protrusion 3 d of the locking portion 3 a constituting the elastic locking operation portion 3 of the protective tube connector 5. It has become.

ここで、保護管SPを更に押し込むようにすると、図2(c)に示すように、保護管SPの先端外周の山部側面が、係止部3aの挿入ガイド部3eに接触し、これにより、弾性係止操作部3の係止部3aが受け口1の外側方向(受け口1の径方向)に撓んだ状態となる。   Here, when the protective tube SP is further pushed in, as shown in FIG. 2C, the crest side surface of the outer periphery of the protective tube SP comes into contact with the insertion guide portion 3e of the locking portion 3a. The locking portion 3a of the elastic locking operation portion 3 is bent in the outer direction of the receiving port 1 (the radial direction of the receiving port 1).

ここで、更に、保護管SPを押し込むと、弾性係止操作部3の係止部3aの突部3dが順に波付き保護管SPの先端外周の山部を乗り越えて行き、保護管SPの先端外周側面が、保護管接続具5の中央仕切り突部5bに接触する位置まで達する。   Here, when the protective tube SP is further pushed in, the protrusion 3d of the locking portion 3a of the elastic locking operation portion 3 sequentially goes over the crest on the outer periphery of the tip of the corrugated protective tube SP, and the tip of the protective tube SP The outer peripheral side surface reaches a position where it comes into contact with the central partition projection 5b of the protective tube connector 5.

ここで、保護管SPを押し込むのを止めると、図2(d)に示すように、弾性係止操作部3の係止部3aの突部3dが保護管SPの最寄りの谷部に入り込んだ状態となる。   Here, when the pushing of the protective tube SP is stopped, as shown in FIG. 2 (d), the protrusion 3d of the locking portion 3a of the elastic locking operation portion 3 enters the nearest valley of the protective tube SP. It becomes a state.

なお、この接続過程において、この保護管接続具5が固定部4により壁面Wに固定されていたとしても、図2(f)から解るように、波付き保護管SPの接続に支障となることがない。   In this connection process, even if the protective tube connector 5 is fixed to the wall surface W by the fixing portion 4, as shown in FIG. 2 (f), the connection of the corrugated protective tube SP is hindered. There is no.

この状態で、波付き保護管SPを引き抜こうとしも、その際には、弾性係止操作部3の抜き出し防止部3fがその抜き出しを阻止するので、引き抜くことはできない。   Even if it is attempted to pull out the corrugated protective tube SP in this state, the pull-out preventing portion 3f of the elastic locking operation portion 3 prevents the pull-out, and therefore cannot be pulled out.

一方、弾性係止操作部3の解除操作部3bを手先Hで押圧すると、図2(e)に示すように、係止部3aが受け口1の外側に撓んで、その先端の突部3dが保護管SPの外周より外側に位置するようになり、容易に、保護管SPを抜き出すこと、つまり、接続解除することができる。   On the other hand, when the release operation portion 3b of the elastic locking operation portion 3 is pressed with the hand H, as shown in FIG. 2 (e), the locking portion 3a is bent to the outside of the receiving port 1, and the protrusion 3d at the tip thereof is It comes to be located outside the outer periphery of the protective tube SP, and the protective tube SP can be easily extracted, that is, disconnected.

この際、少なくとも弾性係止操作部(係止操作部)3は、図2(f)に示すように、接続部2の壁面Wへの当接側以外の位置に設けられいるので、その解除操作に壁面Wが障害となることがない。   At this time, at least the elastic locking operation portion (locking operation portion) 3 is provided at a position other than the contact side to the wall surface W of the connection portion 2 as shown in FIG. The wall surface W does not become an obstacle to the operation.

また、保護管接続具5は、固定部4により壁面W等に固定されているので、保護管SP部分を別途固定する必要がなく、この固定部4は、固定状態であっても、保護管SPの接続、接続解除の支障となることがない。   Further, since the protective tube connector 5 is fixed to the wall surface W or the like by the fixing portion 4, there is no need to separately fix the protective tube SP portion, and this fixing portion 4 can be protected tube even in a fixed state. There is no hindrance to SP connection and disconnection.

こうして、この保護管接続具5によれば、壁面W等に沿って配設される波付き保護管SP同士を抜け止め状態で接続すると共に壁面Wへの固定も可能とし、かつ、その固定状態のままでも、保護管SPの接続が可能となる。   Thus, according to this protective tube connector 5, the corrugated protective tubes SP disposed along the wall surface W and the like are connected to each other in a retaining state and can be fixed to the wall surface W. Even if it remains, the protection tube SP can be connected.

また、この例では、受け口に挿入された保護管に対して、径方向への移動により、該保護管を抜け止め状態に係止し、この係止を解除することを可能とする係止操作部の例として、弾性を利用した係止部3aと解除操作部3bとからなる弾性係止操作部3を示したが、係止操作部としては、これに限定されない。   Also, in this example, a locking operation that allows the protective tube inserted into the receiving port to be locked in a detachable state by moving in the radial direction and to release the lock. As an example of the part, the elastic locking operation part 3 including the locking part 3a using the elasticity and the release operation part 3b is shown, but the locking operation part is not limited to this.

例えば、係止操作部としては、受け口に雌ネジ孔を設け、この雌ネジ孔に係止ネジを入れて、受け口内の保護管の外周に向かって進退させるようなものであってもよい。   For example, as the locking operation portion, a female screw hole may be provided in the receiving port, and a locking screw may be inserted into the female screw hole so as to advance and retreat toward the outer periphery of the protective tube in the receiving port.

図3は、本発明の保護管接続具の他例と、その使用方法を説明するもので、(a)は、接続前の状態を示す斜視図、(b)は保護管接続具に複式保護管を差し込んだ状態を示す断面図、(c)は(b)を手前側から見た正面図である。   3A and 3B illustrate another example of the protective tube connector of the present invention and how to use it. FIG. 3A is a perspective view showing a state before connection, and FIG. Sectional drawing which shows the state which inserted the pipe | tube, (c) is the front view which looked at (b) from the near side.

図4は、図3に続いて保護管接続具の使用方法を説明するもので、(a)は図2(b)から更に差し込まれた複式保護管により弾性係止操作部が撓んでいる状態を示す断面図、(b)は、挿し込みが完了した複式保護管が保護管接続具で抜け止め防止されている状態を示す断面図、(c)は、弾性係止操作部を解除操作して、複式保護管を抜き出そうとしている状態を示す断面図である。   FIG. 4 explains how to use the protective tube connector following FIG. 3. FIG. 4 (a) shows a state where the elastic locking operation portion is bent by the double protective tube further inserted from FIG. 2 (b). (B) is a cross-sectional view showing a state in which the double-type protective tube in which insertion has been completed is prevented from being removed by the protective tube connector, and (c) is a state where the elastic locking operation portion is operated to be released. FIG. 6 is a cross-sectional view showing a state in which a double protection tube is about to be extracted.

この図3、4に示す保護管接続具5Aは、図1の保護管接続具5に比べ、接続部2Aが二つ並列して設けられ、当接面4cは、これら二つの接続部2Aの壁面W等への当接側をつなぐように設けられ、固定部4Aは、この当接面4cに設けられている、つまり、この当接面4cに貫通している固定孔4dを備えている点が異なっている。   The protective tube connector 5A shown in FIGS. 3 and 4 is provided with two connecting portions 2A in parallel as compared with the protective tube connector 5 of FIG. 1, and the abutting surface 4c is formed of the two connecting portions 2A. The fixing portion 4A is provided on the contact surface 4c, that is, includes a fixing hole 4d penetrating through the contact surface 4c. The point is different.

つまり、この保護管接続具5Aは、単体の波付き保護管SPを並列させ、軸方向に沿って連結部PAによって連結された複式保護管WPを接続するために用いられるもので、この連結部PAを逃がすために、連結部挿入空間2aが、並列した接続部2Aの中間部分に設けられている。   In other words, this protective tube connector 5A is used to connect a single protective tube with undulation SP in parallel and connect the multiple protective tube WP connected by the connecting portion PA along the axial direction. In order to allow PA to escape, the connecting portion insertion space 2a is provided in an intermediate portion of the parallel connecting portions 2A.

また、この保護管接続具5Aでは、弾性係止操作部3が、それぞれの接続部2A毎に設けられ、かつ、片手で操作可能なように、接続部2Aの反隣接側に、対向して設けられている。   Moreover, in this protective tube connector 5A, the elastic locking operation part 3 is provided for each connection part 2A and is opposed to the opposite side of the connection part 2A so that it can be operated with one hand. Is provided.

この保護管接続具5Aによって、複式保護管WPを接続し、接続解除する方法は、この図3(b)、(c)、図4で示すように、概ね、図2で説明した図1の保護管接続具5によるものと同じであるので、重複説明を省略し、この場合の特徴点だけについて説明する。   As shown in FIGS. 3 (b), 3 (c), and 4, the method of connecting and disconnecting the duplex protection tube WP with the protection tube connector 5A is generally the same as that shown in FIG. Since it is the same as that by the protective tube connector 5, duplication description is abbreviate | omitted and only the feature point in this case is demonstrated.

図3(a)から解るように、この保護管接続具5Aでは、接続部2Aが二列用のものなので、それぞれの接続部2Aの壁面等への当接側を連結するだけで当接面4c(固定部4A)が形成され、図1の保護管接続具5のように接続部2から張り出した形で当接面4a(固定部4)を形成する必要がないので、それだけ固定部4Aがコンパクトで、コスト安のものとなる。   As can be seen from FIG. 3 (a), in this protective tube connector 5A, since the connecting portions 2A are for two rows, the abutting surfaces can be obtained simply by connecting the abutting sides of the connecting portions 2A to the wall surface or the like. 4c (fixed portion 4A) is formed, and it is not necessary to form the contact surface 4a (fixed portion 4) in a form protruding from the connected portion 2 as in the protective tube connector 5 of FIG. Is compact and cheap.

また、この固定部4Aは、二列の接続部2Aの中央に設けられ、固定作用がバランスして作用するので、片持ち固定となる保護管接続具5の固定部4に比べ、バランスがよい。なお、保護管接続具5において、バランスを良くするには、固定部4を接続部2の両側に設けるようにすればよい。   In addition, the fixing portion 4A is provided at the center of the two rows of connecting portions 2A, and the fixing action acts in a balanced manner. . In order to improve the balance in the protective tube connector 5, the fixing portions 4 may be provided on both sides of the connection portion 2.

また、この保護管接続具5Aでは、弾性係止操作部3は、接続部2Aの反隣接側に、対向して設けられているので、図4(c)で示すように、接続解除操作も、人の手先Hで同時にでき、作業性が良い。   Further, in this protective tube connector 5A, the elastic locking operation part 3 is provided on the opposite side of the connection part 2A so as to face the connection part 2A. Therefore, as shown in FIG. It can be done at the same time with human hand H, and workability is good.

また、図4(c)で解るように、この保護管接続具5Aでは、固定部4Aで固定された状態でも、接続解除操作を支障なくすることができる。   In addition, as can be seen from FIG. 4C, in this protective tube connector 5A, the connection release operation can be prevented even when the protective tube connector 5A is fixed by the fixing portion 4A.

こうして、この保護管接続具5Aによれば、複式保護管についても、壁等に沿って配設される保護管同士を接続すると共に壁面への固定も可能とし、かつ、その固定状態のままで、保護管の接続解除を可能とすることができる。   In this way, according to this protective tube connector 5A, the protective tubes arranged along the walls and the like can be connected to each other and fixed to the wall surface with respect to the duplex protective tube, and the fixed tube can be fixed. The connection of the protective tube can be released.

加えて、この保護管接続具5Aによれば、固定部4Aがコンパクトで、コスト安で、バランスの良いものとなる。   In addition, according to this protective tube connector 5A, the fixing portion 4A is compact, inexpensive, and well-balanced.

図5(a)は、本発明の保護管接続具の他例を示す側面図、(b)は、(a)の正面図、(c)は、本発明の保護管接続具の他例を示す側面図である。   FIG. 5 (a) is a side view showing another example of the protective tube connector of the present invention, (b) is a front view of (a), and (c) is another example of the protective tube connector of the present invention. FIG.

図5(a)、(b)に示す保護管接続具5Bは、背景技術である図6(b)の保護管接続具30と同様に、接続部2Bが、多数の係止部2bを備え、本体部5bに対して回動操作されることで、波付き保護管を接続、接続解除することができるものである。   The protective tube connector 5B shown in FIGS. 5 (a) and 5 (b) is similar to the protective tube connector 30 in FIG. 6 (b), which is the background art, and the connecting portion 2B includes a number of locking portions 2b. By rotating the main body 5b, the corrugated protective tube can be connected and disconnected.

係止部2bを備えた接続部2Bは、図5(b)に示すように、本体部5bに対して、目印「接続」の相対的回転位相位置にあるときは、保護管を、その受け口1Aに挿入した際、係止部2bが弾性変形して、この保護管を受け入れ、抜き出しが出来ないように接続保持する。   As shown in FIG. 5 (b), the connecting portion 2B provided with the locking portion 2b has a protective tube connected to its receiving port when it is in the relative rotational phase position of the mark “connection” with respect to the main body portion 5b. When inserted into 1A, the locking portion 2b is elastically deformed to accept this protective tube and keep it connected so that it cannot be pulled out.

一方、接続部2Bは、本体部5bに対して、目印「解除」の相対的回転位相位置にあるときは、係止部2bが弾性変形して、保護管の外周に接触しないように広がり、保護管を容易に抜き出すことができるようにするものであり、実施例1の解除操作部に相当するものである。   On the other hand, when the connecting portion 2B is in the relative rotational phase position of the mark “release” with respect to the main body portion 5b, the locking portion 2b is elastically deformed so as not to contact the outer periphery of the protective tube, The protective tube can be easily extracted and corresponds to the release operation unit of the first embodiment.

加えて、この保護管接続具5Bは、接続部2Bの壁面への当接側から壁面に向けて伸び出した当接面4eと、該当接面4eを壁面に当接させた状態でこの保護管接続具を該壁面に釘やビス等により固定可能とする固定孔4fとを備えた固定部4Bを備えている。   In addition, the protective tube connector 5B has the contact surface 4e extending from the contact side to the wall surface of the connecting portion 2B toward the wall surface, and this protection in a state where the corresponding contact surface 4e is in contact with the wall surface. A fixing portion 4B having a fixing hole 4f that enables the pipe connector to be fixed to the wall surface with a nail, a screw or the like is provided.

この固定部4Bは、接続部2Bより離隔した当接面4eにより、図5(a)、(b)に二点鎖線の想像線で壁面Wを示すように、壁面Wへの固定状態でも、接続部2Bの回動操作、つまり、接続解除操作に支障とならないものである。   The fixed portion 4B is fixed to the wall surface W as shown by the phantom line of the two-dot chain line in FIGS. 5 (a) and 5 (b) by the contact surface 4e separated from the connection portion 2B. This does not hinder the turning operation of the connecting portion 2B, that is, the connection releasing operation.

この保護管接続具5Bは、図1の保護管接続具5に比べ、係止操作部(係止部2bを備えた接続部2B)が弾性係止操作部である点は共通するが、回動操作により接続解除をするものである点、当接面4eが接続部2Bの外周に対して離隔している点が異なるが、他の点では共通するものであり、図1の保護管接続具5と同様の作用効果を発揮するものである。   Compared to the protective tube connector 5 of FIG. 1, this protective tube connector 5B is common in that the locking operation portion (the connecting portion 2B having the locking portion 2b) is an elastic locking operation portion. 1 is different in that the connection is released by a dynamic operation, and the contact surface 4e is separated from the outer periphery of the connection portion 2B. The same effect as the tool 5 is exhibited.
