Description

本発明は、配線・配管材のわん曲部を内部に挿通して、そのわん曲姿勢を維持するための配線・配管材のわん曲姿勢維持具に関するものである。 The present invention relates to a wiring / pipe material bending posture maintaining tool for inserting a bending portion of wiring / piping material into the inside and maintaining the bending posture.

本明細書に使用される「係止構造部」とは、特定部材の係止部と、対応する被係止部とが相互に外れないように係止可能な部分を指し、その結果、「係止構造部」とは、係止部と被係止部との双方を含む概念であって、係止部と被係止部とが係止された状態、及び未係止の状態の双方を含むことになる。 As used herein, the “locking structure portion” refers to a portion that can be locked so that the locking portion of the specific member and the corresponding locked portion are not separated from each other. `` Locking structure part '' is a concept that includes both a locking part and a locked part, both in a state where the locking part and the locked part are locked and in an unlocked state. Will be included.

軸方向に連設されることで筒状をした従来のわん曲姿勢維持具として、特許文献１に開示のものが知られている。このわん曲姿勢維持具は、筒本体の軸方向に沿って所定間隔をおいて周方向に沿った特定部に切欠き部が形成され、当該筒本体の軸方向の一端から配線・配管材を挿通した状態で、当該配線・配管材を筒本体と一緒に屈曲させることで、前記各切欠き部の対向部に設けられた係止部と被係止部を互いに係止させることで、管本体の屈曲状態を維持する構成である。 As a conventional bending posture maintaining tool having a cylindrical shape by being continuously provided in the axial direction, one disclosed in Patent Document 1 is known. This curved posture maintaining tool has a notch formed in a specific portion along the circumferential direction at a predetermined interval along the axial direction of the cylinder body, and the wiring / pipe material is connected from one end of the cylinder body in the axial direction. By bending the wiring / piping material together with the cylinder body in the inserted state, the locking portion and the locked portion provided in the opposing portion of each notch portion are locked to each other. It is the structure which maintains the bending state of a main body.

このため、上記したわん曲姿勢維持具は、予め配線・配管材を内部に挿通した後に、配線・配管材と筒本体とを一緒に屈曲させる必要があり、配線・配管材が予め屈曲された状態で、当該配線・配管材のわん曲部を筒本体の内部に挿入させることは不能なため、配線・配管の各工程の順序が制約されて、配線・配管材の自由度が少なくなる問題があった。また、筒本体における切欠き部と対向する部分は、連続されているため、前記係止により筒本体をわん曲させた状態において、当該筒本体は、原形状である直線状に戻ろうとする復元力が作用するため、当該復元力により当該係止が解除されてしまう問題もあった。 For this reason, the above-mentioned curved posture maintaining tool needs to bend the wiring / pipe material and the tube body together after the wiring / pipe material is inserted in advance, and the wiring / pipe material is bent in advance. In this state, it is impossible to insert the bent portion of the wiring / piping material into the cylinder body, which restricts the order of the wiring / piping processes and reduces the degree of freedom of the wiring / piping material. was there. Further, since the portion facing the notch portion in the cylinder main body is continuous, in a state where the cylinder main body is bent by the locking, the cylinder main body is restored to return to the original linear shape. Since the force acts, there is also a problem that the locking is released by the restoring force.

本発明は、配線・配管材をわん曲させた後においても、当該わん曲部に対して「後付け」で装着可能であって、しかも維持具本体に設けられた径方向及び軸方向に沿った２種類の各係止構造部の係止及びその解除の操作を容易にすることを課題としている。 The present invention can be attached to the bent portion by “retrofitting” even after the wiring / pipe material is bent, and is in the radial direction and the axial direction provided in the maintenance tool body. It is an object to facilitate the operation of locking and releasing the two types of locking structures.

上記課題を解決するための請求項１の発明は、複数の保護筒体が軸方向に沿った連設部により連設されて、内部に配線・配管材が配設される配設経路が設けられた筒状の維持具本体を備え、
前記配線・配管材のわん曲形状に対応させて前記連設部を屈曲させて、隣接する保護筒体の軸心の相互の傾斜角を変更させることで、内部の配設経路に挿通される配線・配管材のわん曲形状を維持させるわん曲姿勢維持具であって、
前記各保護筒体には、径方向から前記配線・配管材を内部に受入れ可能とする分断部が軸方向に設けられ、当該分断部には、当該分断部の閉じた状態を維持する第１係止構造部が設けられ、
隣接する各保護筒体には、一方の保護筒体に設けられた重合係止板部が、他方の保護筒体に前記軸方向に沿って部分重合された状態で互いに係止されることで、各軸心を相互に傾斜させた状態を維持する第２係止構造部が設けられていることを特徴としている。 In order to solve the above-mentioned problem, the invention according to claim 1 is provided with a disposition path in which a plurality of protective cylinders are continuously disposed by a continuous portion along the axial direction, and wiring / piping materials are disposed therein. Provided with a cylindrical maintenance tool body,
The connecting portion is bent corresponding to the curved shape of the wiring / piping material, and the mutual inclination angle of the axes of the adjacent protective cylinders is changed to be inserted into the internal arrangement path. A curved posture maintaining tool that maintains the curved shape of wiring and piping materials,
Each of the protective cylinders is provided with a dividing portion that can receive the wiring / piping material from the inside in the radial direction, and the dividing portion includes a first portion that maintains a closed state of the dividing portion. A locking structure is provided,
In each of the adjacent protective cylinders, the overlapping locking plate portion provided on one protective cylindrical body is locked to each other in a state of being partially polymerized along the axial direction with the other protective cylindrical body. The second locking structure portion that maintains the state in which the respective axes are inclined with respect to each other is provided.

請求項１の発明によれば、配線・配管材の必要部を予めわん曲させておき、分断部が開口された維持具本体の当該分断開口を通して、配線・配管材のわん曲部を維持具本体の内部に収容した後に、わん曲姿勢維持具の分断部を閉じると、全ての第１係止構造部により、前記分断部が閉じた状態を維持させると同時に、前記第２係止構造部のうち、その全て、又は特定部のみが係止状態となって、配線・配管材のわん曲姿勢が維持される。このように、請求項１の発明によれば、予めわん曲された配線・配管材のわん曲部に対して維持具本体を装着すること、即ち、維持具本体の「後付け」が可能となると共に、前記第２係止構造部により係止状態が維持されることで、互いの軸心が交差（傾斜）する隣接する保護筒体の数の選択により、配線・配管材の異なるわん曲姿勢（わん曲角度）に対しても対応可能となる。また、軸方向の全長に亘って開口された分断部の当該分断開口を通して配線・配管材のわん曲部を、維持具本体の径方向に移動させて、その内部に収容できるので、配線・配管材の配設作業の制約が少なくなって、その効率が高められる。 According to the first aspect of the present invention, the necessary portion of the wiring / piping material is bent in advance, and the bent portion of the wiring / piping material is maintained through the dividing opening of the maintenance tool body in which the dividing portion is opened. When the dividing portion of the bending posture maintaining tool is closed after being accommodated in the main body, the first locking structure portion keeps the divided portion closed by all the first locking structure portions, and at the same time, the second locking structure portion Among them, all or only a specific part is in a locked state, and the bending posture of the wiring / pipe material is maintained. As described above, according to the first aspect of the present invention, it is possible to attach the maintenance tool main body to the bent portion of the wiring / pipe material that is bent in advance, that is, it is possible to “retrofit” the maintenance tool main body. In addition, since the locked state is maintained by the second locking structure portion, different bending postures of the wiring / pipe material can be obtained by selecting the number of adjacent protective cylinders whose axis centers intersect (inclined). (Curved angle) can also be supported. In addition, the curved portion of the wiring / pipe material can be moved in the radial direction of the maintenance tool main body through the dividing opening of the dividing portion opened over the entire length in the axial direction and accommodated in the inside thereof. The restriction of the material arrangement work is reduced and the efficiency is increased.

また、第２係止構造部は、隣接する各保護筒体の一方に設けられた重合係止板部を、他方の保護筒体に軸方向に沿って部分重合された状態で互いに係止されることで、隣接する保護筒体の各軸心を相互に傾斜させた状態を維持する構造であるので、前記分断部の閉じた状態を維持する第１係止構造部の係止状態の解除には、前記第２係止構造部の係止状態が解除されていることが必要である。よって、軸方向に連続している複数の保護筒体の途中の部分から、分断部を開口させることは難しいために、分断部は、容易には開口されない。このため、分断部を開口させるには、軸方向の一端から他端に向けて、第２係止構造部の係止状態を解除させることで、第１係止構造部が自動的に解除されて、分断部を開口させる操作が容易となる。 In addition, the second locking structure portion is locked to each other in a state in which the overlapping locking plate portion provided on one of the adjacent protective cylinders is partially polymerized along the axial direction with the other protective cylinder. Since the structure in which the axes of the adjacent protective cylinders are inclined with respect to each other is maintained, the locked state of the first locking structure portion that maintains the closed state of the divided portion is released. It is necessary that the locked state of the second locking structure portion is released. Therefore, since it is difficult to open a parting part from the middle part of a plurality of protective cylinders that are continuous in the axial direction, the parting part is not easily opened. For this reason, in order to open the dividing portion, the first locking structure portion is automatically released by releasing the locking state of the second locking structure portion from one end to the other end in the axial direction. Thus, the operation of opening the dividing portion becomes easy.

なお、直状の維持具本体の分断部を開口させ、当該分断開口を通して維持具本体の内部に直状の配線・配管材を収容した後に、配線・配管材と維持具本体とを一緒にわん曲させることも可能であり、この場合においても、維持具本体の軸方向の一端から配線・配管材を挿通する必要がないので、従来構造のわん曲姿勢維持具に比較して、配線・配管材の配設作業は容易となる。 In addition, after opening the dividing part of the straight maintenance tool main body and storing the straight wiring / piping material inside the maintenance tool main body through the dividing opening, the wiring / piping material and the maintenance tool main body are folded together. It is possible to bend, and even in this case, there is no need to insert wiring / piping material from one end of the maintenance tool main body in the axial direction. The material arrangement work becomes easy.

請求項２の発明は、請求項１の発明において、前記第２係止構造部は、隣接する保護筒体の一方に設けられた一対の重合係止板部と、他方の保護筒体に設けられた一対の被係止部とから成り、前記一対の重合係止板部の内側に他方の保護筒体の一対の被係止部が挿入された状態で互いに係止され、
前記第１係止構造部の係止状態の解除により、前記分断部を開口させることで、前記一対の重合係止板部と前記一対の被係止部とで構成される第２係止構造部の係止状態が解除される構成であることを特徴としている。 According to a second aspect of the present invention, in the first aspect of the invention, the second locking structure portion is provided on a pair of overlapping locking plate portions provided on one of the adjacent protective cylinders and on the other protective cylinder.

In a state where the bent portions of the protective tube P ₁ and the main body tube P ₂ are bent and bent, the upper end portion of the bent portion is bound to the side column 51 by the binding tape 52, and The length of the maintenance tool main body 1 along the axial direction is two to three times the length of the protective cylinder A, and like the plurality of protective cylinders A, a pair of half cylinders B ₁ , B ₂ (B ′ ₁ , B ′ ₂ ). The pair of shaft end protection cylinders B and B ′ is a _first member for maintaining the closed state of the dividing portion 2 of the pair of half cylinders B ₁ and B ₂ (B ′ ₁ and B ′ ₂ ). provided stop structure E _1, the half cylindrical body B _1, B ₂ constituting the one axial end protective pipe B, to maintain the bent position between the protective pipe a which is adjacent to the inner The pair of half cylinders B ′ ₁ and B ′ ₂ that are each provided with the latched piece 10 and constitute the other shaft end protection cylinder B ′ are adjacent protection cylinders. In order to maintain a bending posture with A, locking grooves 9 are respectively provided.

図４（ｂ）に示されるように、第１係止構造部Ｅ₁が係止状態であって、一対の半割短筒体Ａ₁，Ａ₂の各分断面２ａ，２ｂが近接又は密着して、分断開口１３が無くなって、内部に配設経路５が形成された状態では、当該配設経路５の横断面は、通常の管体の横断面に対応した円形であって、しかも管体（実施例１では、二重配管された保護管Ｐ₁及び本体管Ｐ₂）の外周面と配設経路５の内周面との間の隙間は、僅かとなっている。この隙間が小さいことで、わん曲姿勢維持具Ｍ₁の配設経路５内において管体の径方向の移動量が少なくなり、管体のわん曲姿勢を、わん曲姿勢維持具Ｍ₁の屈曲姿勢に追従させることが可能となって、管体のわん曲姿勢の維持状態が安定する。 As shown in FIG. 4B, the first locking structure E ₁ is in the locked state, and the divided sections 2a and 2b of the pair of half-short cylinders A ₁ and A ₂ are close or in close contact with each other. When the dividing opening 13 is eliminated and the arrangement path 5 is formed inside, the cross section of the arrangement path 5 is a circle corresponding to the cross section of a normal tubular body, and the pipe The gap between the outer peripheral surface of the body (in the first embodiment, the protective pipe P ₁ and the main body pipe P _2, which are double-pipe) and the inner peripheral surface of the arrangement path 5 is small. The gap that is small, less amount of movement of the radial direction of the tube in the distribution設経path 5 Curved position maintaining device M _1, the Curved orientation of the tube body, bending of Curved position maintaining device M ₁ It becomes possible to follow the posture, and the maintenance state of the curved posture of the tube is stabilized.

一対の軸端保護筒体Ｂ，Ｂ’の端部側には、わん曲姿勢において、維持具本体１と側方の支柱５１と結束テープ５２とで結束する際に、当該結束テープ５２が維持具本体１の軸心方向にずれるのを防止する一対のずれ防止フランジ部１７が前記軸心方向に沿って所定間隔をおいて設けられている。軸端保護筒体Ｂ，Ｂ’の外周面における前記一対のずれ防止フランジ部１７には、１本の周方向リブ１８と計４本の軸方向リブ１９とが交差して設けられていて、各リブ１８，１９及び前記一対のずれ防止フランジ部１７で囲まれる部分は、凹部２１となっている。各リブ１８，１９の高さ（厚さ）は、同一であって、前記一対のずれ防止フランジ部１７の各軸端保護筒体Ｂ，Ｂ’の外周面からの径方向に沿った突出長は、前記各リブ１８，１９の高さ（厚さ）よりも大きいので、各軸方向リブ１９と一対のずれ防止フランジ部１７との間には、所定の段差が形成されている。配線・配管作業の関係では、わん曲姿勢維持具Ｍ₁の両端の各軸端保護筒体Ｂ，Ｂ’の部分に、係止構造を利用して、配管部材が係止されることになり、この場合において、前記凹部２１は、当該係止を確実にすると共に、複数の軸方向リブ１９が周方向に沿って一定間隔をおいて設けられることで、係止状態の前記配管部材がわん曲姿勢維持具Ｍ₁に対して廻るのを防止できる。 On the end side of the pair of shaft end protection cylinders B and B ′, the binding tape 52 is maintained when the maintenance tool main body 1, the side column 51 and the binding tape 52 are bound together in a curved posture. A pair of slip prevention flange portions 17 for preventing the tool body 1 from shifting in the axial direction is provided at predetermined intervals along the axial direction. One pair of circumferential ribs 18 and a total of four axial ribs 19 intersect each other in the pair of shift prevention flange portions 17 on the outer peripheral surfaces of the shaft end protection cylinders B and B ′. A portion surrounded by each of the ribs 18 and 19 and the pair of shift prevention flange portions 17 is a recess 21. The heights (thicknesses) of the ribs 18 and 19 are the same, and the protrusion length along the radial direction from the outer peripheral surface of each of the shaft end protection cylinders B and B ′ of the pair of shift prevention flange portions 17. Is larger than the height (thickness) of each of the ribs 18 and 19, a predetermined step is formed between each of the axial ribs 19 and the pair of deviation preventing flange portions 17. In relation to wiring and piping work, the piping member is locked to the shaft end protection cylinders B and B ′ at both ends of the bending posture maintaining tool M ₁ by using a locking structure. In this case, the concave portion 21 ensures the locking, and the plurality of axial ribs 19 are provided at regular intervals along the circumferential direction, so that the pipe member in the locked state is trapped. Liaoning's can be prevented for the song posture device for maintaining M _1.

そして、二重配管された保護管Ｐ₁及び本体管Ｐ₂を予め所定角度（実施例１では、９０°）だけわん曲させておき、この状態で、上記のわん曲姿勢維持具Ｍ₁を用いて、保護管Ｐ₁及び本体管Ｐ₂のわん曲部のわん曲姿勢を維持させるには、以下のようにして行う。また、図１に示されるように、わん曲姿勢維持具Ｍ₁（維持具本体１）の分断部２を大きく開口させて、保護管Ｐ₁及び本体管Ｐ₂のわん曲部の外側（わん曲中心が存在しない側）に、分断部２が大きく開いたわん曲姿勢維持具Ｍ₁（維持具本体１）をあてがい、この状態で、一対の半割筒体３の分断開口１３を小さくしながら、保護管Ｐ₁及び本体管Ｐ₂のわん曲部のわん曲形状に倣って、維持具本体１の全体を変形させると、各保護筒体Ａを構成する一対の半割短筒体Ａ₁，Ａ₂及び各軸端保護筒体Ｂ，Ｂ’を構成する一対の半割筒体Ｂ₁，Ｂ₂（Ｂ'₁，Ｂ'₂）の対向する分断面２ａ，２ｂが近接することで、一方の半割短筒体Ａ₁の係止板部１１が、他方の半割短筒体Ａ₁の方形短筒部１４に挿入されて、係止板部１１により被係止爪片部１２が方形短筒部１４の天壁部１４ａの側に弾性変形された後に原形状に復元されることで、係止板部１１の先端の係止部１１ｂと、被係止爪片部１２の被係止爪部１５とが係止されて、分断開口１３が閉じられることで、一対の半割短筒体Ａ₁，Ａ₂及び一対の半割筒体Ｂ₁，Ｂ₂（Ｂ'₁，Ｂ'₂）は、係止連結状態となって、分断部２が開かない状態となる。 Then, the protective pipe P ₁ and the main pipe P ₂ that are double-pipe are bent in advance by a predetermined angle (90 ° in the first embodiment), and in this state, the bent posture maintaining tool M ₁ is attached. In order to maintain the bending postures of the bending portions of the protective tube P ₁ and the main body tube P ₂ , it is performed as follows. Further, as shown in FIG. 1, the dividing portion 2 of the bending posture maintaining tool M ₁ (maintenance tool main body 1) is greatly opened, and the outer side of the bending portion of the protective pipe P ₁ and the main body pipe P ₂ (the bending). A curved posture maintaining tool M ₁ (maintenance tool main body 1) with the dividing portion 2 wide open is applied to the side where the bending center does not exist, and in this state, the dividing openings 13 of the pair of half cylinders 3 are made small. When the entire maintenance tool main body 1 is deformed following the curved shape of the bent portions of the protective tube P ₁ and the main body tube P _2, a pair of half-short cylinders A ₁ constituting each protective cylinder A , A ₂ and the pair of halved cylinders B ₁ , B ₂ (B ′ ₁ , B ′ ₂ ) that constitute the shaft end protection cylinders B, B ′ are close to each other in close proximity to each other. , one half locking plate portion 11 of the short tube bodies a ₁ is inserted into the rectangular short cylinder portion 14 of the other half short tube bodies a _1, Hikakaritometsume piece by the locking plate 11 2 is elastically deformed to the top wall portion 14a side of the rectangular short tube portion 14 and then restored to the original shape, whereby the locking portion 11b at the tip of the locking plate portion 11 and the locked claw piece portion 12 are restored. The latching claw portion 15 is locked and the dividing opening 13 is closed, so that the pair of half-short cylindrical bodies A ₁ and A ₂ and the pair of half-cylindrical bodies B ₁ and B ₂ (B ′ ₁ , B ′ ₂ ) is in a locked and connected state, and the dividing portion 2 is not opened.

上記の作用と並行して、保護管Ｐ₁及び本体管Ｐ₂のわん曲部のわん曲形状に倣って、隣接する保護筒体Ａどうし、及び各軸端保護筒体Ｂ，Ｂ’とその内側で隣接する保護筒体Ａとが僅かに屈曲されることで、同一直線上に配置されていた各軸心が交差（傾斜）状態となり、この途中において、隣接する保護筒体Ａの一方の一対の被係止片部１０が、他方の保護筒体Ａを構成していて、近接途中の他方の保護筒体Ａの一対の重合係止板部８の間に入り込んで重合状態となる。そして、第１係止構造部Ｅ₁の係止が完成される直前においては、一方の保護筒体Ａの一対の係止溝部９と、他方の保護筒体Ａの一対の被係止片部１０とは、軸方向に沿ってほぼ同一位置に配置されているが、未係止状態である。次に、保護筒体Ａを構成する一対の半割短筒体Ａ₁，Ａ₂の各分断面２ａ，２ｂが近接又は密着すると、第２係止構造部Ｅ₂を構成する一方の保護筒体Ａの一対の係止溝部９と、他方の保護筒体Ａの一対の被係止片部１０との係止が完成される。即ち、第１及び第２の各係止構造部Ｅ₁，Ｅ₂の係止の時間的な経過をほぼ同時的に進行することになる。なお、各軸端保護筒体Ｂ，Ｂ’の第１係止構造部Ｅ₁の係止の完成、及び各軸端保護筒体Ｂ，Ｂ’と、その内側で隣接する保護筒体Ａとの間の第２係止構造部Ｅ₂の係止の完成も、上記した隣接する各保護筒体Ａの関係と同一である。 In parallel with the above operation, the protection cylinders A adjacent to each other and the shaft end protection cylinders B and B ′ and their shapes follow the curved shapes of the curved portions of the protection pipe P ₁ and the main body pipe P _2. By slightly bending the adjacent protective cylinder A on the inner side, the axes arranged on the same straight line are crossed (inclined), and in the middle of this, one of the adjacent protective cylinders A A pair of to-be-latched piece part 10 comprises the other protection cylinder A, and it enters between the pair of superposition latching plate parts 8 of the other protection cylinder A in the middle of proximity, and it will be in a superposition | polymerization state. And just before the locking of the first locking structure E ₁ is completed, the pair of locking grooves 9 of one protective cylinder A and the pair of locked pieces of the other protective cylinder A 10 is arranged at substantially the same position along the axial direction, but is in an unlocked state. Next, when the divided sections 2a and 2b of the pair of half-short cylinders A ₁ and A ₂ constituting the protective cylinder A come close to or in close contact with each other, one of the protective cylinders constituting the second locking structure portion E ₂ The engagement between the pair of locking groove portions 9 of the body A and the pair of locked piece portions 10 of the other protective cylinder A is completed. That is, the time passage of the locking of the first and second locking structures E ₁ and E ₂ proceeds almost simultaneously. In addition, completion of latching of the first latching structure portion E ₁ of each shaft end protection cylinder B, B ′, and each shaft end protection cylinder B, B ′, and the protection cylinder A adjacent inside thereof second completion of engagement of the interlocking structure portion E ₂ between the also the same as the relationship of each protective pipe a which is adjacent to the above.

これにより、図５〜図７に示されるように、複数の保護筒体Ａ及び両端の一対の軸端保護筒体Ｂ，Ｂ’における互いに隣接する保護筒体Ａどうし、及び軸端の軸端保護筒体Ｂ，Ｂ’とその内側で隣接する保護筒体Ａとは、全て薄肉連設部６で屈曲されることで、９０°にわん曲された保護管Ｐ₁及び本体管Ｐ₂の屈曲角度θ₀（＝９０°）のわん曲姿勢は、二重配管された保護管Ｐ₁及び本体管Ｐ₂の外側に装着されたわん曲姿勢維持具Ｍ₁により維持される。実施例１では、複数の保護筒体Ａ及び両端の各軸端保護筒体Ｂ，Ｂ’の「屈曲構造部」の屈曲角度θ₁は、（９０°）であると共に、「屈曲構造部」の数は、「９」であって、全ての「屈曲構造部」で屈曲されているので、わん曲姿勢維持具Ｍ₁の全体としての屈曲角度θ₀は、（１０°×９＝９０°）となる。 Accordingly, as shown in FIGS. 5 to 7, the protection cylinders A adjacent to each other in the plurality of protection cylinders A and the pair of shaft end protection cylinders B and B ′ at both ends, and the shaft ends of the shaft ends The protective cylinders B and B ′ and the protective cylinder A adjacent to the inside of the protective cylinders B and B ′ are all bent by the thin-walled continuous portion 6 so that the protective pipe P ₁ and the main pipe P ₂ bent at 90 ° are formed. The bent posture of the bending angle θ ₀ (= 90 °) is maintained by the bent posture maintaining tool M ₁ mounted on the outside of the protective pipe P ₁ and the main pipe P _{2 that} are double-pipe. In the first embodiment, the bending angle θ ₁ of the “bending structure part” of the plurality of protective cylinders A and the shaft end protection cylinders B and B ′ at both ends is (90 °) and “bending structure part”. Is 9 and is bent by all the “bending structure portions”, the bending angle θ ₀ as a whole of the bending posture maintaining tool M ₁ is (10 ° × 9 = 90 °). )

上記した配管例は、予め管体を所定角度でわん曲させておき、当該管体のわん曲部に「後付け」でわん曲姿勢維持具Ｍ₁を装着する例であって、軸方向に沿った分断部２を有する本発明に係るわん曲姿勢維持具Ｍ₁の特有の利点である。しかし、わん曲姿勢維持具Ｍ₁の内部の配設経路予定部に管体を挿入しておいて、当該管体とわん曲姿勢維持具Ｍ₁とを一緒に所定角度だけわん曲させる配管も可能である。後者の配管例においても、従来構造のわん曲姿勢維持具と異なって、管体は、わん曲姿勢維持具の径方向に移動させることで、わん曲姿勢維持具の内部に挿入できる利点がある。なお、実施例１のわん曲姿勢維持具Ｍ₁では、隣接する保護筒体Ａ及び両端の各側端保護筒体Ｂと保護筒体Ａとの間に設けられた全ての第２係止構造部Ｅ₂を係止状態にしても、管体のわん曲角度は，９０°であって、管体が鋭角にわん曲させられないため、座屈するおそれもない。 Piping example described above, allowed to curved beforehand pipe at a predetermined angle, a case for mounting the "retrofit" Dewan song position maintaining device M ₁ in the curved portion of the tube, along the axial direction This is a unique advantage of the curved posture maintaining tool M _{1 according} to the present invention having the dividing portion 2. However, keep in inserting a tube into distribution設経path plan portion of the interior of Curved position maintaining device M _1, also pipe by a predetermined angle Dakewan songs and the tube body and bend in position maintaining device M ₁ together Is possible. Also in the latter piping example, unlike the bending posture maintenance tool of the conventional structure, the pipe body has an advantage that it can be inserted into the bending posture maintenance tool by moving in the radial direction of the bending posture maintenance tool. . In Example 1 Luwan song position maintaining device M _1, all of the second locking structure provided between the protective pipe A and the side end protective pipe ends B adjacent to the protective pipe A Even when the portion E ₂ is in the locked state, the bending angle of the tube body is 90 °, and the tube body cannot be bent at an acute angle, so there is no possibility of buckling.

また、第２係止構造部Ｅ₂は、隣接する各保護筒体Ａの一方に設けられた重合係止板部８を、他方の保護筒体Ａに軸方向に沿って部分重合させることで、隣接する保護筒体Ａの一方の係止溝部９に他方の保護筒体Ａの被係止片部１０を係止させることで、隣接する保護筒体Ａの各軸心を相互に傾斜させた状態で維持する構造である。このため、前記分断部２の閉じた状態を維持する第１係止構造部Ｅ₁の係止状態の解除には、前記第２係止構造部Ｅ₂の係止状態が解除されていることが必要である。よって、軸方向に連続している複数の保護筒体Ａの途中の部分から、分断部２を開口させることは難しいために、管体にわん曲姿勢維持具Ｍ₁が装着された状態において、分断部２は、容易には開口されない。このため、分断部２を開口させるには、軸方向の一端から他端に向けて、第２係止構造部Ｅ₂の係止状態を解除させることで、第１係止構造部Ｅ₁が自動的に解除されて、分断部２を開口させる操作が容易となる。 In addition, the second locking structure portion E ₂ is obtained by partially polymerizing the overlapping locking plate portion 8 provided on one of the adjacent protective cylinders A on the other protective cylinder A along the axial direction. By locking the locked piece 10 of the other protective cylinder A in one locking groove 9 of the adjacent protective cylinder A, the axes of the adjacent protective cylinders A are inclined with respect to each other. It is a structure that maintains it in a heated state. Thus, wherein the release of the locked state of the first interlocking structure portion E ₁ to maintain the closed state of the divided portion 2, the second locked state of the interlocking structure portion E ₂ is released is necessary. Therefore, since it is difficult to open the dividing portion 2 from the middle portion of the plurality of protective cylinders A that are continuous in the axial direction, in the state where the curved posture maintaining tool M ₁ is attached to the tubular body, The dividing part 2 is not easily opened. Therefore, in order to open the cutting portion 2, toward the other end from the one axial end, by releasing the second locked state of the interlocking structure portion E _2, the first interlocking structure portion E ₁ It is automatically released and the operation of opening the dividing portion 2 becomes easy.

なお、図７に示される配管例は、床材５３の下方の床下部に配管された保護管Ｐ₁及び本体管Ｐ₂を９０°だけ屈曲させて、床材５3 に設けられた貫通孔５４を通して、床材５３の上方に起立配管させる例であり、床下部では、保護管Ｐ₁及び本体管Ｐ₂は、下地部５５の上に配管されている。 In the piping example shown in FIG. 7, the protective pipe P ₁ and the main pipe P ₂ piped below the floor 53 below the floor 53 are bent by 90 °, and the through hole 54 provided in the floor 53 is provided. In this example, the protective pipe P ₁ and the main body pipe P ₂ are piped on the base part 55 in the lower part of the floor.

また、屈曲されて起立配管された保護管Ｐ₁及び本体管Ｐ₂の全体の配管姿勢を保持させる必要が生じた場合には、図８に示されるように、配管の起立部の側方に支柱５１を設けて、当該支柱５１と、保護管Ｐ₁及び本体管Ｐ₂のわん曲部の外側に装着されたわん曲姿勢維持具Ｍ₁の起立側の軸端保護筒体Ｂの一対のずれ防止フランジ部１７との間に、結束テープ５２を巻回することで、当該結束テープ５２が管軸方向にずれることなく、屈曲された保護管Ｐ₁及び本体管Ｐ₂の起立部の全体を当該支柱５１に保持させる。これにより、保護管Ｐ₁及び本体管Ｐ₂の起立配管部の全体の起立配管姿勢を長期に亘って安定して維持できる。なお、わん曲姿勢維持具Ｍ₁のヒンジ連結部４を含めて全てのヒンジ連結部４は、軸端保護筒体Ｂの外周面に対して径方向に突出しているが、当該各ヒンジ連結部４は、屈曲の外側に配置されて、支柱５１に対して対向配置されていて、結束テープ５２の巻回面とはならないため、当該結束テープ５２の巻回の支障とならない。 Further, when it is necessary to maintain the entire piping posture of the protection pipe P ₁ and the main body pipe P ₂ bent and standing, as shown in FIG. A support 51 is provided, and a pair of shifts between the support 51 and the shaft end protection cylinder B on the upright side of the bending posture maintaining tool M ₁ mounted outside the bent portions of the protective pipe P ₁ and the main pipe P _2. By winding the binding tape 52 between the prevention flange portion 17 and the binding tape 52 is not displaced in the tube axis direction, the entire standing portion of the bent protective tube P ₁ and the main body tube P ₂ is removed. The column 51 is held. This allows stably maintained over the entire upright pipe posture of standing pipe portion of the protective pipe P ₁ and the main body tube P ₂ long term. Incidentally, all of the hinge connecting portion 4 including a hinged portion 4 of Curved position maintaining member M ₁ is protruding radially with respect to the outer peripheral surface of the shaft end protective pipe B, the respective hinged portions 4 is arranged on the outer side of the bend and is opposed to the support column 51 and does not become a winding surface of the binding tape 52, so that it does not hinder the winding of the binding tape 52.

また、上記したわん曲姿勢維持具Ｍ₁の屈曲角度θ₀（＝９０°）は、管体をわん曲させて起立配管させるという、本発明に係るわん曲姿勢維持具Ｍ₁の最も使用頻度の高い屈曲角度であるが、図９に示されるように、複数の第２係止構造部Ｅ₂のうち特定の第２係止構造部Ｅ₂のみを係止状態にして、隣接する複数組の保護筒体Ａのうち特定組の保護筒体Ａどうしを屈曲させることで、鈍角にわん曲された管体のわん曲部のわん曲姿勢を維持させることも可能である。図９は、傾斜壁５７は、水平壁５６に対して鈍角に傾斜していて、水平壁５６と傾斜壁５７とに亘って管体（保護管Ｐ₁及び本体管Ｐ₂）が配管されて、上記したわん曲姿勢維持具Ｍ₁により、管体の鈍角わん曲部の傾斜姿勢（傾斜角度＝１４０°）を維持している。即ち、隣接する複数組の保護筒体Ａのうち一つおきの組の保護筒体Ａどうしを第２係止構造部Ｅ₂で係止させて、その軸心を交差（傾斜）させていて、残りの組の保護筒体Ａどうしの軸心は、同一直線上に配置されている。具体的には、保護筒体Ａの数は、「８」であって、「隣接する保護筒体Ａの組数」は、「８」であり、軸心が交差している「隣接する保護筒体Ａの組数」は、１つおきであって、「４」であり、隣接する保護筒体Ａの交差（傾斜）角度θ₁（＝１０°）であるので、わん曲姿勢維持具Ｍ₁の屈曲角度θ₀は、〔１８０°−（４×１０°）＝１４０°〕となって、管体のわん曲部のわん曲姿勢を維持できる。 In addition, the bending angle θ ₀ (= 90 °) of the bending posture maintaining tool M ₁ described above is the most frequently used frequency of the bending posture maintaining tool M _{1 according to} the present invention in which the pipe body is bent and the upright piping is performed. As shown in FIG. 9, only a specific second locking structure E ₂ out of the plurality of second locking structures E ₂ is locked, and a plurality of adjacent sets It is also possible to maintain the bending posture of the bent portion of the tubular body bent at an obtuse angle by bending a specific set of the protective cylinders A among the protective cylinders A. In FIG. 9, the inclined wall 57 is inclined at an obtuse angle with respect to the horizontal wall 56, and pipe bodies (protective pipe P ₁ and main body pipe P ₂ ) are piped across the horizontal wall 56 and the inclined wall 57. The inclined posture (inclination angle = 140 °) of the obtuse bent portion of the tubular body is maintained by the bending posture maintaining tool M ₁ described above. That is, every other set of adjacent protective cylinders A among the adjacent multiple sets of protective cylinders A is locked by the second locking structure E ₂ , and the axes are crossed (inclined). The axes of the remaining pairs of protective cylinders A are arranged on the same straight line. Specifically, the number of the protection cylinders A is “8”, the “number of adjacent protection cylinders A” is “8”, and the “adjacent protections” in which the axes intersect each other. “The number of sets of cylinders A” is every other, and is “4”, and is the intersection (inclination) angle θ ₁ (= 10 °) of adjacent protective cylinders A. The bending angle θ ₀ of M ₁ is [180 ° − (4 × 10 °) = 140 °], and the bending posture of the bending portion of the tubular body can be maintained.

上記から明らかなように、実施例１のわん曲姿勢維持具Ｍ₁により、管体のわん曲姿勢を維持できる上記角度以外のわん曲角は、理論上は、１００°，１１０°，１２０°，１３０°，１５０°，１６０°，１７０°である。 As is apparent from the above, the bending angles other than the above-mentioned angles at which the bending posture maintaining tool M ₁ of the first embodiment can maintain the bending posture of the tube body are theoretically 100 °, 110 °, 120 °. , 130 °, 150 °, 160 °, and 170 °.

また、何らかの原因で、管体の外側に装着されて、そのわん曲を維持しているわん曲姿勢維持具Ｍ₁を取り外す必要が生じた場合には、図３及び図４において、半割短筒体Ａ₂に設けられた解除操作部１６に、当該解除操作部１６が保護筒体Ａから離れる側の力を作用させると、第１係止構造部Ｅ₁の係止状態、即ち、半割短筒体Ａ₁の側の被係止爪部１５と、半割短筒体Ａ₁の側の係止部１１ｂとの係止状態が解除されて、一対の半割短筒体Ａ₁，Ａ₂の分断部２が開くことで、第２係止構造部Ｅ₂の係止状態、即ち、隣接する保護筒体Ａの一方の一対の被係止片部１０と、他方の保護筒体Ａの一対の係止溝部９との係止状態も、同時に解除される。即ち、解除操作部１６に対して当該解除操作部１６が保護筒体Ａから離れる側の力を作用させることで、第１及び第２の各係止構造部の係止状態は、並行してほぼ同時に解除されるため、係止解除の操作が容易となり、この点も，本発明の利点の一つである。 If for some reason it becomes necessary to remove the bending posture maintaining tool M ₁ that is attached to the outside of the tubular body and maintains its bending, the half length is shortened in FIGS. When a force on the side away from the protective cylinder A is applied to the release operation part 16 provided in the cylinder A ₂ , the first locking structure E ₁ is locked, that is, half comparatively short tube bodies the engageable claw part 15 side of the a _1, half engaged state is released with the engaging portion 11b on the side of the short tube bodies a _1, a pair of half short tube bodies a ₁ , A ₂ dividing portion 2 is opened, so that the second locking structure E ₂ is locked, that is, one pair of locked pieces 10 of the adjacent protective cylinder A and the other protective cylinder. The locked state of the body A with the pair of locking groove portions 9 is also released at the same time. That is, by applying a force on the release operation portion 16 on the side where the release operation portion 16 is separated from the protective cylinder A, the locking states of the first and second locking structure portions are in parallel. Since it is released at almost the same time, the operation of releasing the lock becomes easy, which is one of the advantages of the present invention.

また、実施例１のわん曲姿勢維持具Ｍ₁を構成する複数の保護筒体Ａは、軸方向に沿って同一に配置されている。即ち、各保護筒体Ａは、軸方向の両端部にそれぞれ重合係止板部８及び被係止片部１０が設けられていて、複数の保護筒体Ａの連設状態において、各保護筒体Ａに設けられた重合係止板部８及び被係止片部１０は、いずれも同一の方向を向いている。しかし、図１０に示される実施例２のわん曲姿勢維持具Ｍ₂は、軸方向の中央に配置された一つの保護筒体Ａ’は、軸方向の両端部に、いずれも第２係止構造部Ｅ₂を構成する係止溝部９が設けられていて，その両側にそれぞれ配置される保護筒体Ａは、軸方向の両端部に、それぞれ重合係止板部８及び被係止片部１０が設けられているが、中央の保護筒体Ａ’に対して対称に配設されている点が、実施例１のわん曲姿勢維持具Ｍ₁と異なる。 Further, a plurality of protective pipe A which constitutes the first embodiment Luwan song position maintaining member M ₁ is disposed on the same along the axial direction. That is, each protective cylinder A is provided with a superposition locking plate portion 8 and a locked piece portion 10 at both ends in the axial direction, respectively. The overlapped locking plate portion 8 and the locked piece portion 10 provided on the body A are all directed in the same direction. However, in the bending posture maintaining tool M2 of the _second embodiment shown in FIG. 10, one protective cylinder A ′ disposed at the center in the axial direction is provided with the second engaging portions at both ends in the axial direction. Locking groove portions 9 constituting the structure portion E ₂ are provided, and the protective cylinders A respectively disposed on both sides thereof are overlapped with the overlapping locking plate portions 8 and the locked piece portions at both ends in the axial direction. 10 is different from the curved posture maintaining tool M _{1 of the} first embodiment in that it is disposed symmetrically with respect to the central protective cylinder A ′.

上記実施例１，２では、維持具本体１を構成する一対の半割筒体３は、複数のヒンジ連結部４において連結された構造であるが、維持具本体１を構成する一対の半割筒体３は、分離された別体構造であって、ヒンジ連結部４の部分で結合される構成であってもよい。 In the first and second embodiments, the pair of halved cylinders 3 constituting the maintenance tool body 1 are connected to each other at the plurality of hinge connecting portions 4. The cylindrical body 3 may be a separate structure separated from each other, and may be configured to be coupled at the hinge connecting portion 4.

上記実施例のわん曲姿勢維持具Ｍ₁，Ｍ₂は、軸方向の両端に軸端保護筒体Ｂ，Ｂ’が設けられていて、当該軸端保護筒体Ｂ，Ｂ’を結束テープの巻回部として利用することが可能であるが、本発明においては、複数の保護筒体Ａのみでわん曲姿勢維持具Ｍ₁，Ｍ₂を構成することも可能である。 The bent posture maintaining tools M ₁ and M ₂ of the above embodiment are provided with shaft end protection cylinders B and B ′ at both ends in the axial direction, and the shaft end protection cylinders B and B ′ are attached to the binding tape. Although it can be used as a winding portion, in the present invention, it is also possible to configure the bent posture maintaining tools M ₁ and M ₂ with only a plurality of protective cylinders A.
