Description

本発明は、路上に立設された車止め用支柱などの柱状体や、水道管、ガス管などの管状体などに、チェーン、ロープ、ワイヤー、掛止フックなどの取付対象を、ねじ構造を介して連結固定するための連結具に関する。 The present invention is intended to attach a chain, a rope, a wire, a hook, etc., to a columnar body such as a car-supporting column standing on the road or a tubular body such as a water pipe or a gas pipe via a screw structure. It is related with the connector for connecting and fixing.

例えば特許文献１には、隣接する防護柵用支柱の間に車止め用のチェーンを連結するための連結具が開示されている。連結具は、円板状のフランジと、フランジの一方の面に突出される一対の弾性爪とを備えたプラスチック成形品からなり、フランジの中央にはチェーンを連結するためのねじ孔が設けられている。中空円筒状の支柱の周面には挿入孔が穿設されており、一対の弾性爪を挿入孔を介して支柱内に押し込むことにより、連結具を支柱に固定できる。また、支柱に固定されたフランジのねじ孔に、アイボルトのねじ軸をねじ込むことにより、チェーンをアイボルトを介して連結具に取り付けることができる。 For example, Patent Literature 1 discloses a connecting tool for connecting a chain for stopping a car between adjacent guard fence posts. The connector consists of a plastic molded product with a disc-shaped flange and a pair of elastic claws protruding on one surface of the flange, and a screw hole for connecting the chain is provided at the center of the flange. ing. An insertion hole is formed in the peripheral surface of the hollow cylindrical column, and the coupling tool can be fixed to the column by pushing a pair of elastic claws into the column through the insertion hole. Further, by screwing the screw shaft of the eyebolt into the screw hole of the flange fixed to the support column, the chain can be attached to the connector via the eyebolt.

特許文献２の連結具は、棒材を挟持する一対の狭持片からなる係合体と、係合体に外嵌して各狭持片が開かないように拘束する係合体固定部材とで構成される。係合体には雌ねじ部が設けてあり、係合体固定部材には雌ねじ部に臨む貫通孔が設けてある。フック状の保持具に挿通したビスを、係合体固定部材の貫通孔を介して係合体の雌ねじ部にねじ込むことにより、フック状の保持具を連結具に取り付けている。このように、特許文献２の連結具は、棒材に穿孔を形成する必要もなく、棒材を抱持する状態で取り付けることができる。 The coupling tool of Patent Document 2 includes an engaging body composed of a pair of holding pieces that sandwich a bar, and an engaging body fixing member that is externally fitted to the engaging body and restrains each holding piece from being opened. The The engaging body is provided with a female screw portion, and the engaging body fixing member is provided with a through hole facing the female screw portion. The hook-shaped holding tool is attached to the coupling tool by screwing the screw inserted through the hook-shaped holding tool into the female thread portion of the engaging body through the through hole of the engaging body fixing member. As described above, the connector disclosed in Patent Document 2 can be attached in a state in which the bar is held without the need to form a hole in the bar.

特開平０７−２５９０３９号公報Japanese Patent Application Laid-Open No. 07-259039 特開２０１０−５３９５０号公報（段落番号００１４、図５）JP 2010-53950 A (paragraph number 0014, FIG. 5)

特許文献１の連結具は、予め支柱に挿入孔を設けておく必要があるため、例えば、既設の支柱を利用してチェーンを掛け渡し、臨時の車止めを構成したいような場合に対応できない。また、いたずら等によってチェーンに大きな力が加えられるような場合に、弾性爪が破損し、あるいは連結具が挿入孔から脱落するおそれがあり、連結具の適用対象が、比較的小さな力が加わる状況に限られてしまう。また、孔を開けることができない水道管やガス管などに特許文献１の連結具を取り付けることはできない。 Since it is necessary to provide the insertion hole in the support column in advance, the connector disclosed in Patent Document 1 cannot cope with a case in which an existing support column is used to span a chain and a temporary vehicle stop is configured. In addition, when a large force is applied to the chain due to mischief, etc., there is a risk that the elastic claw may be damaged or the coupling tool may fall out of the insertion hole, and the application target of the coupling tool is subject to a relatively small force. It will be limited to. Moreover, the coupler of patent document 1 cannot be attached to a water pipe, a gas pipe, etc. which cannot open a hole.

特許文献２の係合体は、棒材の形状や太さに対応した専用品であるため、連結具を製品化する際には、棒材の形状等の違いに応じて幾種類もの係合体と係合体固定部材を用意する必要がある。そのため、係合体と係合体固定部材の形状が異なるごとに複数種の金型を用意せざるを得ず、部品の製造コストや管理コストが高く付く。 Since the engaging body of Patent Document 2 is a dedicated product corresponding to the shape and thickness of the bar material, when commercializing the connector, there are several types of engaging bodies depending on the shape of the bar material and the like.

本発明では、構造体Ｐに巻回したバンド体２をバンド締付構造３で締付固定する。バンド締付構造３は、バンド体２の一対の締付部１６の間に挟持されるスペーサ９と、締付ボルト１１および締付ナット１２とを含む。締付ボルト１１および締付ナット１２でスペーサ９と一対の締付部１６とを同時に締結することにより、バンド体２の外接部１５を構造体Ｐの外周面に密着固定する。以上のように構成したバンド締付構造３は、構造体Ｐの構造や形状とは無関係に共通部品化できる。また、バンド締付構造３に設けるねじ体４も、同様に共通部品化できる。このように、バンド締付構造３およびねじ体４を共通部品化すると、構造や形状が異なる多種類の構造体Ｐに対して、１種類のバンド締付構造３およびねじ体４を用意すればよく、バンド締付構造３の構成部品やねじ体４の製造に要するコストを大幅に削減でき、管理コストも少なくて済む。 In the present invention, the band body 2 wound around the structure P is fastened and fixed by the band tightening structure 3. The band tightening structure 3 includes a spacer 9 sandwiched between a pair of tightening portions 16 of the band body 2, a tightening bolt 11, and a tightening nut 12. By simultaneously tightening the spacer 9 and the pair of tightening portions 16 with the tightening bolt 11 and the tightening nut 12, the circumscribed portion 15 of the band body 2 is closely fixed to the outer peripheral surface of the structure P. The band tightening structure 3 configured as described above can be made into a common part regardless of the structure and shape of the structure P. Moreover, the screw body 4 provided in the band fastening structure 3 can be similarly made into a common part. As described above, when the band fastening structure 3 and the screw body 4 are made into a common part, if one kind of band fastening structure 3 and the screw body 4 are prepared for various types of structures P having different structures and shapes. The cost required for manufacturing the components of the band fastening structure 3 and the screw body 4 can be greatly reduced, and the management cost can be reduced.

金属板材を素材とするプレス加工品でバンド体２を形成すると、外接部１５の形状が異なる複数種のバンド体２を簡単に製造することができる。つまり本発明によれば、構造体Ｐの構造や形状に対応した専用品であるバンド体２を安価に製造することができ、従って、全体として低コストで連結具１を製造できる。また、バンド体２が金属板材を素材とすると、外接部１５を容易に拡径させて、一対の締付部１６の間隔を拡げることができ、構造体Ｐの所望位置にバンド体２を素早く装着できる。さらに、無端状の構造体Ｐにも問題無くバンド体２を装着できる。 When the band body 2 is formed of a press-processed product made of a metal plate material, a plurality of types of band bodies 2 having different shapes of the circumscribed portion 15 can be easily manufactured. That is, according to the present invention, the band body 2 which is a dedicated product corresponding to the structure and shape of the structure P can be manufactured at low cost, and thus the connector 1 can be manufactured at a low cost as a whole. Further, when the band body 2 is made of a metal plate material, the circumscribed portion 15 can be easily expanded in diameter, and the distance between the pair of tightening portions 16 can be increased, and the band body 2 can be quickly placed at a desired position of the structure P. Can be installed. Furthermore, the band body 2 can be attached to the endless structure P without any problem.

一対の締付部１６の外面を化粧カバー１０で覆うと、連結具１の外観をすっきりとした見栄えの良いものにすることができる。化粧カバー１０を、締付ボルト１１および締付ナット１２で、スペーサ９および締付部１６と同時に締結すると、化粧カバー１０を固定するための構造を締付ボルト１１および締付ナット１２とは別に設ける場合に比べて部品点数を削減して、連結具１の低コスト化を図ることができる。 When the outer surfaces of the pair of tightening portions 16 are covered with the decorative cover 10, the appearance of the connector 1 can be made clean and good-looking. When the decorative cover 10 is fastened simultaneously with the spacer 9 and the fastening portion 16 with the fastening bolt 11 and the fastening nut 12, the structure for fixing the decorative cover 10 is separate from the fastening bolt 11 and the fastening nut 12. Compared with the case where it provides, the number of parts can be reduced and the cost of the coupler 1 can be reduced.

連結具のねじ体をナット４で構成すると、既製品を利用して連結具１の製造コストを削減できる。また、ナット４を受ける受座２６をスペーサ９に設け、受座２６を構成する一対の保持体２７で、ナット４を回転不能に保持し、受座２６を構成する受面２８と化粧カバー１０の端壁３６とで、ナット４を軸心方向に移動不能に挟み固定する。つまり、スペーサ９と化粧カバー１０とを利用してナット４を固定保持するので、部品点数が増えるのを避けて、連結具１の低コスト化を図ることができる。さらに、締付部１６と基部２４と受座２６とナット４との外面を化粧カバー１０で覆うと、連結具１の外観をすっきりとした見栄えの良いものにすることができる。 When the screw body of the connector is constituted by the nut 4, the manufacturing cost of the connector 1 can be reduced by using the ready-made product. A receiving seat 26 for receiving the nut 4 is provided on the spacer 9, and a pair of holding bodies 27 constituting the receiving seat 26 holds the nut 4 in a non-rotatable manner, and the receiving surface 28 constituting the receiving seat 26 and the decorative cover 10. With the end wall 36, the nut 4 is sandwiched and fixed so as not to move in the axial direction. That is, since the nut 4 is fixedly held using the spacer 9 and the decorative cover 10, the number of parts can be prevented from increasing, and the cost of the connector 1 can be reduced. Furthermore, when the outer surfaces of the tightening portion 16, the base portion 24, the seat 26, and the nut 4 are covered with the decorative cover 10, the appearance of the connector 1 can be made clean and good-looking.

締付ボルト１１の操作頭部５６を第１対向壁３４の第１通口３７に入り込ませて、締付部１６の外面に密着させると、第１対向壁３４を締結するのを避けて、一対の締付部１６とスペーサ９と第２対向壁３５との四者だけを締結することができる。このように、化粧カバー１０の一方の対向壁３４を締結するのを避けると、両対向壁３４・３５が接近する方向に化粧カバー１０を変形させなくても、一対の締付部１６を互いの接近方向に締め付けることができる。従って、スペーサ９の基部２４と一対の締付部１６とを加えた厚み寸法が、両対向壁３４・３５の対向間隔に比べて極端に小さい場合にも、一対の締付部１６を確実に締め付けて、バンド体２を構造体Ｐに確りと固定できる。 When the operation head 56 of the tightening bolt 11 enters the first passage 37 of the first opposing wall 34 and is brought into close contact with the outer surface of the tightening portion 16, the first opposing wall 34 is avoided from being fastened. Only the four members of the pair of tightening portions 16, the spacer 9, and the second opposing wall 35 can be fastened. In this way, if one of the facing walls 34 of the decorative cover 10 is avoided from being fastened, the pair of tightening portions 16 can be connected to each other without deforming the decorative cover 10 in a direction in which the opposing walls 34 and 35 approach each other. It can be tightened in the approaching direction. Therefore, even when the thickness dimension including the base portion 24 of the spacer 9 and the pair of tightening portions 16 is extremely smaller than the facing distance between the opposing walls 34 and 35, the pair of tightening portions 16 can be reliably secured. The band body 2 can be securely fixed to the structure P by tightening.

締付ナット１２の係合部４６と第２通口３８との間に回り止め構造を設けて、締付ナット１２を回転不能に保持すると、締付ボルト１１を回動操作する際に、締付ナット１２が回転しないように保持する必要が無いので、締付ボルト１１の回動操作を簡便に行うことができる。 If a locking structure is provided between the engaging portion 46 of the tightening nut 12 and the second passage 38 so that the tightening nut 12 is held unrotatable, the tightening bolt 11 is turned when the tightening bolt 11 is rotated. Since it is not necessary to hold the attaching nut 12 so as not to rotate, the turning operation of the tightening bolt 11 can be easily performed.

Corresponding to the engaging portion 46, the second opening 38 of the second facing wall 35 is also formed in a non-circular shape having a non-rotating surface 49 made of a flat surface. By engaging the engaging portion 46 with the second passage 38, the anti-rotation surfaces 48 and 49 come into contact with each other, so that the tightening nut 12 is held non-rotatably with respect to the decorative cover 10. As shown in FIG. 5, the width dimension in the front-rear direction (axial direction of the screw hole 47) of the engaging portion 46 of the tightening nut 12 and the front-rear thickness dimension of the second opposing wall 35 are set to be the same. The second facing wall 35 is sandwiched between the nut body 45 and the tightening portion 16.

締付ボルト１１は六角穴付ボルトであり、締付ナット１２のねじ孔４７にねじ込まれるねじ軸５５と、ねじ軸５５の一端に設けられる円柱状の操作頭部５６とを一体に備える。操作頭部５６の径寸法は、化粧カバー１０の第１通口３７のそれより小さく、かつ、締付部１６の締付孔１８のそれより大きく設定されている。操作頭部５６の前部は第１通口３７内に収容されて、締付ナット１２と対向する操作頭部５６の締付面５７が、締付部１６の外面に密着する。図６は、本実施形態に係る連結具１の六面図である。この六面図において、底面図は平面図と対称にあらわれるため省略する。 The tightening bolt 11 is a hexagon socket head cap screw, and integrally includes a screw shaft 55 screwed into the screw hole 47 of the tightening nut 12 and a columnar operation head 56 provided at one end of the screw shaft 55. The diameter of the operation head 56 is set smaller than that of the first opening 37 of the decorative cover 10 and larger than that of the tightening hole 18 of the tightening portion 16. The front portion of the operation head 56 is accommodated in the first passage 37, and the tightening surface 57 of the operation head 56 facing the tightening nut 12 is in close contact with the outer surface of the tightening portion 16. FIG. 6 is a hexahedral view of the connector 1 according to the present embodiment. In this six-face drawing, the bottom view is omitted because it is symmetrical with the plan view.

連結具１を支柱Ｐに取り付けるには、まず支柱Ｐの上端部から外接部１５を挿通して、バンド体２を支柱Ｐに装着する。次いで、六角ナット４が仮組みされたスペーサ９を締付部１６の間に挿入し、スペーサ９および締付部１６の外側に化粧カバー１０を被せる。最後に締付ナット１２を化粧カバー１０の第２通口３８に係合し、締付ボルト１１を、化粧カバー１０の第１通口３７、一方の締付孔１８、スペーサ９の切欠２９、他方の締付孔１８の順に挿通させて、締付ナット１２にねじ込む。 In order to attach the connector 1 to the column P, first, the band body 2 is attached to the column P by inserting the circumscribed portion 15 from the upper end of the column P. Next, the spacer 9 on which the hexagon nut 4 is temporarily assembled is inserted between the tightening portions 16, and the decorative cover 10 is placed on the outside of the spacer 9 and the tightening portion 16. Finally, the tightening nut 12 is engaged with the second through hole 38 of the decorative cover 10, and the tightening bolt 11 is connected to the first through hole 37 of the decorative cover 10, the one tightening hole 18, the notch 29 of the spacer 9, The other tightening hole 18 is inserted in this order and screwed into the tightening nut 12.

締付ボルト１１を締付ナット１２にねじ込むと、締付ボルト１１の操作頭部５６と締付ナット１２のナット本体４５とにより、一対の締付部１６とスペーサ９と第２対向壁３５とが締結されて、バンド体２とスペーサ９と化粧カバー１０との三者が互いに遊動不能に固定される。同時に、一対の締付部１６が接近方向に締め付けられて、外接部１５が縮径方向に引き寄せられ、これにより外接部１５が支柱Ｐに圧接して、バンド体２が支柱Ｐに固定される。 When the tightening bolt 11 is screwed into the tightening nut 12, the operation head 56 of the tightening bolt 11 and the nut body 45 of the tightening nut 12 cause the pair of tightening portions 16, the spacer 9, and the second opposing wall 35 to be connected. Is fastened, and the three members of the band body 2, the spacer 9, and the decorative cover 10 are fixed to each other so as not to move freely. At the same time, the pair of tightening portions 16 are tightened in the approaching direction, and the circumscribed portion 15 is drawn in the reduced diameter direction, whereby the circumscribed portion 15 is pressed against the support P and the band body 2 is fixed to the support P. .

連結具１にチェーンＱを連結するには、まずアイボルトＲを連結具１に取り付ける。具体的には、図１に示すように、アイボルトＲの雄ねじ体Ｓを化粧カバー１０の第３通口３９を介して六角ナット４にねじ込む。次いで、アイボルトＲのリング部分の向きを決めてから、雄ねじ体Ｓの外周面に螺合されたロックナットＴをスパナなどで掴んで、締込方向に回動操作する。ロックナットＴと六角ナット４とで端壁３６を内外から締結することにより、アイボルトＲを連結具１に回転不能に固定することができる。最後に、取り付けたアイボルトＲのリング部分に、カラビナＵを介してチェーンＱを連結する。なお、アイボルトＲの雄ねじ体Ｓの先端は、スペーサ９の切欠２９に入り込んでいる。このように、スペーサ９の内部に雄ねじ体Ｓの先端が入り込むようにすると、雄ねじ体Ｓが連結具１の外面から大きく突出するのを避けることができる。 In order to connect the chain Q to the connector 1, first, the eyebolt R is attached to the connector 1. Specifically, as shown in FIG. 1, the male screw body S of the eyebolt R is screwed into the hexagon nut 4 through the third opening 39 of the decorative cover 10. Next, after the direction of the ring portion of the eyebolt R is determined, the lock nut T screwed to the outer peripheral surface of the male screw body S is grasped with a spanner or the like and rotated in the tightening direction. By fastening the end wall 36 from inside and outside with the lock nut T and the hexagon nut 4, the eyebolt R can be fixed to the connector 1 in a non-rotatable manner. Finally, the chain Q is connected to the ring portion of the attached eyebolt R via the carabiner U. The tip of the male screw body S of the eyebolt R enters the notch 29 of the spacer 9. Thus, if the front end of the male screw body S enters the inside of the spacer 9, it can be avoided that the male screw body S largely protrudes from the outer surface of the connector 1.

以上のように、本実施形態に係る連結具１は、支柱Ｐに巻回したバンド体２をバンド締付構造３で締付固定する。バンド締付構造３は、バンド体２の一対の締付部１６の間に挟持されるスペーサ９と、締付ボルト１１および締付ナット１２とを含む。締付ボルト１１および締付ナット１２でスペーサ９と一対の締付部１６とを同時に締結することにより、バンド体２の外接部１５を構造体Ｐの外周面に密着固定する。以上のように構成したバンド締付構造３は、支柱Ｐの構造や形状とは無関係に共通部品化できる。また、バンド締付構造３に設けるねじ体４も、同様に共通部品化できる。このように、バンド締付構造３およびねじ体４を共通部品化すると、構造や形状が異なる多種類の支柱Ｐに対して、１種類のバンド締付構造３およびねじ体４を用意すればよく、バンド締付構造３の構成部品やねじ体４の製造に要するコストを大幅に削減でき、管理コストも少なくて済む。 As described above, the connector 1 according to the present embodiment fastens and fixes the band body 2 wound around the support column P with the band tightening structure 3. The band tightening structure 3 includes a spacer 9 sandwiched between a pair of tightening portions 16 of the band body 2, a tightening bolt 11, and a tightening nut 12. By simultaneously tightening the spacer 9 and the pair of tightening portions 16 with the tightening bolt 11 and the tightening nut 12, the circumscribed portion 15 of the band body 2 is closely fixed to the outer peripheral surface of the structure P. The band tightening structure 3 configured as described above can be formed as a common part regardless of the structure and shape of the support column P. Moreover, the screw body 4 provided in the band fastening structure 3 can be similarly made into a common part. As described above, when the band fastening structure 3 and the screw body 4 are made into a common part, one type of band fastening structure 3 and screw body 4 may be prepared for various types of struts P having different structures and shapes. The cost required for manufacturing the components of the band fastening structure 3 and the screw body 4 can be greatly reduced, and the management cost can be reduced.

金属板材を素材とするプレス加工品でバンド体２を形成すると、外接部１５の形状が異なる複数種のバンド体２を簡単に製造することができる。つまり本実施形態によれば、支柱Ｐの構造や形状に対応した専用品であるバンド体２を安価に製造することができ、従って、全体として低コストで連結具１を製造できる。 When the band body 2 is formed of a press-processed product made of a metal plate material, a plurality of types of band bodies 2 having different shapes of the circumscribed portion 15 can be easily manufactured. That is, according to the present embodiment, the band body 2 which is a dedicated product corresponding to the structure and shape of the support column P can be manufactured at low cost, and thus the connector 1 can be manufactured at a low cost as a whole.

化粧カバー１０を、締付ボルト１１および締付ナット１２で、スペーサ９および締付部１６と同時に締結すると、化粧カバー１０を固定するための構造を締付ボルト１１および締付ナット１２とは別に設ける場合に比べて部品点数を削減して、連結具１の低コスト化を図ることができる。スペーサ９と化粧カバー１０とを利用して六角ナット４を固定保持すると、部品点数が増えるのを避けて、連結具１の低コスト化を図ることができる。締付部１６と基部２４と受座２６と六角ナット４との外面を化粧カバー１０で覆うと、連結具１の外観をすっきりとした見栄えの良いものにすることができる。 When the decorative cover 10 is fastened simultaneously with the spacer 9 and the fastening portion 16 with the fastening bolt 11 and the fastening nut 12, the structure for fixing the decorative cover 10 is separate from the fastening bolt 11 and the fastening nut 12. Compared with the case where it provides, the number of parts can be reduced and the cost of the coupler 1 can be reduced. If the hexagon nut 4 is fixedly held using the spacer 9 and the decorative cover 10, the number of parts can be prevented from increasing, and the cost of the connector 1 can be reduced. When the outer surfaces of the tightening portion 16, the base portion 24, the seat 26, and the hexagon nut 4 are covered with the decorative cover 10, the appearance of the connector 1 can be made clean and attractive.

締付ボルト１１の操作頭部５６を第１対向壁３４の第１通口３７に入り込ませて、締付部１６の外面に密着させると、第１対向壁３４を締結するのを避けて、一対の締付部１６とスペーサ９と第２対向壁３５との四者だけを締結することができる。このように、化粧カバー１０の一方の対向壁３４を締結するのを避けると、両対向壁３４・３５が接近する方向に化粧カバー１０を変形させなくても、一対の締付部１６を互いの接近方向に締め付けることができる。従って、スペーサ９の基部２４と一対の締付部１６とを加えた厚み寸法が、両対向壁３４・３５の対向間隔に比べて極端に小さい場合にも、一対の締付部１６を確実に締め付けて、バンド体２を支柱Ｐに確りと固定できる。締付ナット１２の係合部４６と第２通口３８との間に回り止め構造を設けて、締付ナット１２を回転不能に保持すると、締付ボルト１１を回動操作する際に、締付ナット１２が回転しないように保持する必要が無いので、締付ボルト１１の回動操作を簡便に行うことができる。 When the operation head 56 of the tightening bolt 11 enters the first passage 37 of the first opposing wall 34 and is brought into close contact with the outer surface of the tightening portion 16, the first opposing wall 34 is avoided from being fastened. Only the four members of the pair of tightening portions 16, the spacer 9, and the second opposing wall 35 can be fastened. In this way, if one of the facing walls 34 of the decorative cover 10 is avoided from being fastened, the pair of tightening portions 16 can be connected to each other without deforming the decorative cover 10 in a direction in which the opposing walls 34 and 35 approach each other. It can be tightened in the approaching direction. Therefore, even when the thickness dimension including the base portion 24 of the spacer 9 and the pair of tightening portions 16 is extremely smaller than the facing distance between the opposing walls 34 and 35, the pair of tightening portions 16 can be reliably secured. By tightening, the band body 2 can be securely fixed to the column P. If a locking structure is provided between the engaging portion 46 of the tightening nut 12 and the second passage 38 so that the tightening nut 12 is held unrotatable, the tightening bolt 11 is turned when the tightening bolt 11 is rotated. Since it is not necessary to hold the attaching nut 12 so as not to rotate, the turning operation of the tightening bolt 11 can be easily performed.

なお、本実施形態に係る連結具１を、路上に立設された逆Ｕ字状の車止めなどの構造体Ｐに取り付ける場合には、筒部１５を拡径させて分断部１７を拡げることにより、バンド体２を構造体Ｐに装着する。バンド体２の装着後の手順は先と同様である。本実施形態のように、バンド体２が金属板材を素材とするプレス加工品であると、分断部１７を拡げることができるので、無端状の構造体Ｐにも問題無くバンド体２を装着することができる。 In addition, when attaching the connector 1 which concerns on this embodiment to structures P, such as a reverse U-shaped car stopper standingly arranged on the road, by expanding the diameter of the cylinder part 15 and expanding the dividing part 17 The band body 2 is attached to the structure P. The procedure after the band body 2 is mounted is the same as described above. If the band body 2 is a press-processed product made of a metal plate material as in the present embodiment, the dividing portion 17 can be expanded, so that the band body 2 can be attached to the endless structure P without any problem. be able to.

The hexagonal bolt 4 passes through a hexagonal columnar head 80 fixedly held by the seat 26 of the spacer 9 and the end wall 36 of the decorative cover 10, and the third opening 39 of the end wall 36. A shaft portion 81 exposed on the outer surface is integrally provided. Further, the notch 29 of the spacer 9 is formed by a circular hole that penetrates the base portion 24 in the axial direction of the tightening bolt 11. For example, a hook with an insertion hole can be attached to the connector 1 according to the present embodiment. Specifically, the hook insertion hole is passed through the shaft portion 81, then a nut is screwed into the shaft portion 81, and the hook is fastened by the nut and the end wall 36, thereby fixing the hook to the connector 1. . Since others are the same as 1st Embodiment, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted. In the present embodiment, the spacer 9 having a shape of the notch 29 different from that of each of the above embodiments is used. However, the same spacer 9 as that of each of the above embodiments can be used.

（第６実施形態）図１１は、スペーサ９の一部を変更した第６実施形態を示しており、スペーサ９の各フランジ２５の外面にリブ８５を突設する点が、第１実施形態と相違する。各リブ８５は、支柱Ｐに向かうに従って上下方向（支柱Ｐの軸心方向）の幅寸法が大きくなる三角板状に形成されており、リブ８５の支柱Ｐ側の端面が支柱Ｐの外周面に当接している。アイボルトＲに上下方向の力が加わると、締付ボルト１１の軸心を中心とする傾動モーメントが発生するが、この傾動モーメントをリブ８５で受け止めることができる。従って、バンド締付構造３に加わる上下方向の応力に対する連結具１の強度を上昇させることができる。他は第１実施形態と同じであるので、同じ部材に同じ符号を付してその説明を省略する。 (6th Embodiment) FIG. 11: has shown 6th Embodiment which changed a part of spacer 9, The point which protrudes the rib 85 on the outer surface of each flange 25 of the spacer 9 differs from 1st Embodiment. Is different. Each rib 85 is formed in a triangular plate shape whose width dimension in the vertical direction (axial center direction of the column P) increases toward the column P, and the end surface of the rib 85 on the column P side contacts the outer peripheral surface of the column P. It touches. When a vertical force is applied to the eyebolt R, a tilting moment is generated around the axial center of the tightening bolt 11. This tilting moment can be received by the rib 85. Accordingly, the strength of the connector 1 against the vertical stress applied to the band fastening structure 3 can be increased. Since others are the same as 1st Embodiment, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.

その他、上記各実施形態では、バンド体２を金属製としたが、これを樹脂製などにすることもできる。外接部１５と支柱Ｐとの間にゴム等を配して、支柱Ｐの傷付き防止材や連結具１の滑り止めとすることができる。ねじ体４を受ける受座２６を化粧カバー１０に設けることができる。また、スペーサ９あるいは化粧カバー１０にねじ体４を一体に形成することができる。具体的には、例えば、第３通口３９の周面にねじ溝を形成して、これをねじ体４とすることができる。また、化粧カバー１０の外面にねじ軸を溶着固定して、これをねじ体４とすることができる。 In addition, in each said embodiment, although the band body 2 was made into metal, this can also be made into resin. By providing rubber or the like between the circumscribed portion 15 and the support P, it is possible to prevent damage to the support P or to prevent the connector 1 from slipping. A seat 26 for receiving the screw body 4 can be provided on the decorative cover 10. Further, the screw body 4 can be formed integrally with the spacer 9 or the decorative cover 10. Specifically, for example, a screw groove can be formed on the peripheral surface of the third through-hole 39 to be used as the screw body 4. In addition, a screw shaft can be welded and fixed to the outer surface of the decorative cover 10 to form the screw body 4.

さらに、上記各実施形態では、構造体Ｐとして車止め用支柱を例示したが、これ以外の構造体Ｐとしては、例えば、建物などの外壁に沿って伸びる水道管やガス管を挙げることができる。水平方向に伸びる水道管等に連結具１を介してねじ付きフックを固定すれば、当該フックを物掛け具として使用することができる。連結具１を介して取り付けたフックは、単に水道管等に引っ掛けただけのＳ字状のフックのように、水道管等に沿って摺動することが無く、使い勝手が良い。 Furthermore, in each said embodiment, although the support | pillar for a vehicle stop was illustrated as the structure P, as the structure P other than this, the water pipe and gas pipe which extend along outer walls, such as a building, can be mentioned, for example. If a threaded hook is fixed to the water pipe etc. which extend in the horizontal direction via the connector 1, the said hook can be used as an object hanging tool. The hook attached via the connector 1 does not slide along the water pipe or the like as in the case of an S-shaped hook simply hooked on the water pipe or the like, and is easy to use.
