Description

本発明は、ワイヤーハーネス等を結束するための結束バンドに関するものである。   The present invention relates to a binding band for binding a wire harness or the like.

従来、図３に示すような結束バンドが知られている。この結束バンドは、片面に鋸歯状の係合歯列９５を形成したバンド９２の基端側に、バンド９２の自由端側を挿通させる挿通孔９３を有したバックル部９０を一体に形成し、挿通孔９３の内面に、バンド９２の係合歯列９５の任意の歯（凸部９５ａと凹部９５ｂ）と係合することでバンド９２の戻り方向の移動を阻止する係合爪９６を形成したものである。   Conventionally, a binding band as shown in FIG. 3 is known. In this binding band, a buckle portion 90 having an insertion hole 93 through which the free end side of the band 92 is inserted is integrally formed on the base end side of the band 92 having a sawtooth engagement tooth row 95 formed on one side, On the inner surface of the insertion hole 93, an engagement claw 96 that prevents movement of the band 92 in the return direction by engaging with any tooth (projection 95a and recess 95b) of the engagement tooth row 95 of the band 92 was formed. Is.

この結束バンドを使用する場合は、バンド９２の自由端側をバックル部９０の挿通孔９３に、決まった挿入方向Ｙから挿入する。そうすると、係合歯列９５の任意の歯（凸部９５ａと凹部９５ｂ）に係合爪９６が係合することで、バンド９２を適当な大きさのループで固定することができる。   When using this binding band, the free end side of the band 92 is inserted into the insertion hole 93 of the buckle 90 from the predetermined insertion direction Y. Then, the engagement claw 96 is engaged with any tooth (the convex portion 95a and the concave portion 95b) of the engagement tooth row 95, so that the band 92 can be fixed with a loop having an appropriate size.

また、図４は、例えば特許文献１に記載された別の従来の結束バンドを示す。この結束バンドでは、バンド１０２の表面と裏面に同様な配列の一定ピッチＨの係合歯列１０５をそれぞれ形成し、バックル部１０１の挿通孔１０３の内面に、表面と裏面の係合歯列１０５にそれぞれ係合する係合爪１０４を設けている。   FIG. 4 shows another conventional binding band described in Patent Document 1, for example. In this binding band, engagement teeth rows 105 of a constant pitch H having the same arrangement are formed on the front surface and the back surface of the band 102, respectively, and engagement teeth rows 105 on the front surface and the back surface are formed on the inner surface of the insertion hole 103 of the buckle portion 101. Engaging claws 104 are respectively provided to be engaged with each other.

また、図５は、例えば特許文献１に記載された更に別の従来の結束バンドを示す。この結束バンドでは、バンド１０２の表裏面の左右半分に、ピッチＨを半分ずつずらした２列の係合歯列１０６、１０７をそれぞれ形成し、バックル部１０１の挿通孔１０３に、左側の係合歯列１０６と右側の係合歯列１０７にそれぞれ係合する係合爪１１６、１１７を設けている。
特開平１０−１４７３６１号公報（図７、図８） FIG. 5 shows still another conventional binding band described in Patent Document 1, for example. In this binding band, two rows of engagement tooth rows 106 and 107 each having a pitch H shifted by half are formed on the left and right halves of the front and back surfaces of the band 102, and the left side engagement is formed in the insertion hole 103 of the buckle portion 101. Engagement claws 116 and 117 that engage with the tooth row 106 and the right side engagement tooth row 107 are provided.
Japanese Patent Laid-Open No. 10-147361 (FIGS. 7 and 8)

ところで、図３や図４に示す結束バンドの場合、係合歯列９５、１０５のピッチ毎にバンド９２、１０２を固定するので、ピッチを細かく刻まないと、細かくバンド９２、１０２の締結長さを調節できないが、ピッチを細かくすると、係合歯列の歯の高さが低くなり、係合力が弱くなるという問題がある。また、あまり細かくないピッチで係合歯列を刻んだ場合、バンド９２、１０２の締結長さの調節が大まかになるため、結束したワイヤーハーネスが馴染んできた際に、締め付けが弱くなり、ワイヤーハーネスがずれる可能性もある。   By the way, in the case of the binding band shown in FIGS. 3 and 4, since the bands 92 and 102 are fixed for each pitch of the engaging tooth rows 95 and 105, the fastening length of the bands 92 and 102 is fine unless the pitch is finely cut. However, if the pitch is made fine, there is a problem that the height of the teeth of the engaging tooth row becomes low and the engaging force becomes weak. In addition, when the engagement tooth row is engraved with a pitch that is not very fine, the adjustment of the fastening length of the bands 92 and 102 becomes rough. There is also a possibility of slipping.

その点、図５に示す結束バンドは、バンド１０２の左右で半ピッチずつ係合歯列１０６、１０７の歯の位置をずらしているので、同じピッチで係合歯列を刻んでも、バンド１０２の長さ調節を半ピッチずつ行うことができる。しかし、左右で半ピッチずつずらした場合、バンド１０２の左半分が係合しているとき、右半分が係合していない状態となるため、バンド１０２に捩れが生じたりして、係合が弛む可能性がある。   In that respect, the binding band shown in FIG. 5 has shifted the positions of the teeth of the engagement tooth rows 106 and 107 by a half pitch on the left and right sides of the band 102. The length can be adjusted by half a pitch. However, if the left and right sides of the band 102 are shifted by left and right, when the left half of the band 102 is engaged, the right half is not engaged. There is a possibility of loosening.

本発明は、上記事情を考慮し、締結力を弱まらせずに、細かい間隔でバンドの締結長さを調節できるようにした結束バンドを提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide a binding band that can adjust the fastening length of the band at fine intervals without weakening the fastening force.

請求項５の発明は、請求項３または４に記載の結束バンドであって、前記表用係合爪と裏用係合爪が、前記バンド挿入方向の前後方向に、前記係合歯列のピッチと等しい間隔をあけて複数設けられていることを特徴とする。   The invention of claim 5 is the binding band according to claim 3 or 4, wherein the front engaging claw and the back engaging claw are arranged in the front-rear direction of the band insertion direction. It is characterized in that a plurality are provided with an interval equal to the pitch.

請求項１の発明によれば、次の効果を得ることができる。   According to invention of Claim 1, the following effect can be acquired.

即ち、バンドの表側の係合歯列と裏側の係合歯列が半ピッチずれているから、表側の係合歯列がバックル部の表用係合爪と正しく係合しているとき、裏側の係合歯列は、バックル部の裏用係合爪に対して半ピッチずれた状態（半係合状態）にある。また、その状態から、バンドが半ピッチ分だけ移動すると、今度は、裏側の係合歯列がバックル部の裏用係合爪と正しく係合し、表側の係合歯列が、バックル部の表用係合爪に対して半ピッチずれた状態（半係合状態）となる。   That is, since the front side engaging tooth row and the back side engaging tooth row are shifted by a half pitch, when the front side engaging tooth row is correctly engaged with the front engaging claw of the buckle portion, the back side This engagement tooth row is in a state (half-engaged state) shifted by a half pitch with respect to the back-side engaging claws of the buckle portion. In addition, when the band moves by a half pitch from that state, the back side engagement tooth row correctly engages with the back side engagement claw of the buckle portion, and the front side engagement tooth row is moved to the buckle portion. It will be in the state (half-engaged state) shifted by half pitch with respect to the front engaging claws.

このように、バンドの半ピッチ分の移動毎に、表側と裏側の係合歯列及び係合爪が交互に係合することになる。従って、半ピッチずつの細かい間隔で、バンドの締結長さを調節することができるようになる。   Thus, every time the band is moved by a half pitch, the front and back side engaging teeth and engaging claws are alternately engaged. Therefore, the fastening length of the band can be adjusted at fine intervals of half a pitch.

この場合、バンドの係合歯列のピッチは、バンドの締結長さを調節する間隔の２倍に設定できるから、係合歯列の歯の高さを特に小さくする必要がなく、また、表側か裏側のいずれかは半係合状態にあるものの、反対側は正しい係合状態を維持できることになるので、十分な係合力を発揮することができ、締結強度が不足するおそれはない。また、バンドの左右でバランスが崩れることがなく、バンドに無用な捩れが起きる心配もないので、安定した係合状態を維持できる。   In this case, since the pitch of the engagement tooth row of the band can be set to twice the interval for adjusting the fastening length of the band, it is not necessary to particularly reduce the height of the teeth of the engagement tooth row, and the front side Although either the back side or the back side is in the half-engaged state, the opposite side can maintain the correct engaged state, so that a sufficient engaging force can be exhibited and there is no fear that the fastening strength is insufficient. In addition, the balance between the left and right sides of the band is not lost, and there is no fear of unnecessary twisting of the band, so that a stable engagement state can be maintained.

そのため、締結強度を弱めずに、細かい間隔で締結することが可能となり、ワイヤーハーネスを束ねる際の作業性の向上が図れる。また、細かい間隔で調節できることから、適切な締め付け力でワイヤーハーネスを束ねることができ、ワイヤーハーネスが馴染んできた際のズレ防止を図ることができる。   Therefore, it becomes possible to fasten with a fine space | interval, without weakening fastening strength, and the workability | operativity at the time of bundling a wire harness can be aimed at. Moreover, since it can adjust with a fine space | interval, a wire harness can be bundled with appropriate clamping force, and the shift | offset | difference at the time of the wire harness becoming familiar can be aimed at.

請求項２の発明によれば、次の効果を得ることができる。即ち、バックル部の表用係合爪と裏用係合爪が半ピッチずれて位置しているから、表側の係合歯列がバックル部の表用係合爪と正しく係合しているとき、裏側の係合歯列は、バックル部の裏用係合爪に対して半ピッチずれた状態（半係合状態）にある。また、その状態から、バンドが半ピッチ分だけ移動すると、今度は、裏側の係合歯列がバックル部の裏用係合爪と正しく係合し、表側の係合歯列が、バックル部の表側係合爪に対して半ピッチずれた状態（半係合状態）となる。   According to invention of Claim 2, the following effect can be acquired. That is, since the front engaging claw and the back engaging claw of the buckle portion are located at a half-pitch shift, the front side engaging tooth row is correctly engaged with the front engaging claw of the buckle portion. The back side engagement tooth row is in a state (half-engaged state) shifted by a half pitch with respect to the back-side engaging claws of the buckle portion. In addition, when the band moves by a half pitch from that state, the back side engagement tooth row correctly engages with the back side engagement claw of the buckle portion, and the front side engagement tooth row is moved to the buckle portion. It will be in the state (half-engaged state) shifted by half pitch with respect to the front side engaging claws.

このように、バンドの半ピッチ分の移動毎に、表側と裏側の係合歯列及び係合爪が交互に係合することになる。従って、半ピッチずつの細かい間隔で、バンドの締結長さを調節することができるようになる。   Thus, every time the band is moved by a half pitch, the front and back side engaging teeth and engaging claws are alternately engaged. Therefore, the fastening length of the band can be adjusted at fine intervals of half a pitch.

この場合、バンドの係合歯列のピッチは、バンドの締結長さを調節する間隔の２倍に設定できるから、係合歯列の歯の高さを特に小さくする必要がなく、また、表側か裏側のいずれかは半係合状態にあるものの、反対側は正しい係合状態を維持できることになるので、十分な係合力を発揮することができ、締結強度が不足するおそれはない。また、バンドの左右でバランスが崩れることがなく、バンドに無用な捩れが起きる心配もないので、安定した係合状態を維持できる。   In this case, since the pitch of the engagement tooth row of the band can be set to twice the interval for adjusting the fastening length of the band, it is not necessary to particularly reduce the height of the teeth of the engagement tooth row, and the front side Although either the back side or the back side is in the half-engaged state, the opposite side can maintain the correct engaged state, so that a sufficient engaging force can be exhibited and there is no fear that the fastening strength is insufficient. Further, the balance between the left and right sides of the band is not lost, and there is no fear of unnecessary twisting of the band, so that a stable engagement state can be maintained.

そのため、締結強度を弱めずに、細かい間隔で締結することが可能となり、ワイヤーハーネスを束ねる際の作業性の向上が図れる。また、細かい間隔で調節できることから、適切な締め付け力でワイヤーハーネスを束ねることができ、ワイヤーハーネスが馴染んできた際のズレ防止を図ることができる。   Therefore, it becomes possible to fasten with a fine space | interval, without weakening fastening strength, and the workability | operativity at the time of bundling a wire harness can be aimed at. Moreover, since it can adjust with a fine space | interval, a wire harness can be bundled with appropriate clamping force, and the shift | offset | difference at the time of the wire harness becoming familiar can be aimed at.

請求項３の発明によれば、バックル部の挿入孔にバンドの自由端側を挿入すると、バックル部の係合爪の傾斜壁に対し係合歯列の凸部の傾斜面が摺動することで、凸部が係合爪を乗り越え、凸部の係合面と係合爪の係止壁が係合することで、戻り方向に移動しないようにバンドが係止される。従って、バンドの挿入は容易にできるが、いったん挿入して係合歯列と係合爪が係合すると、確実に戻り方向に移動しないように、バンドを締結することができる。   According to invention of Claim 3, when the free end side of a band is inserted in the insertion hole of a buckle part, the inclined surface of the convex part of an engagement tooth row | line slides with respect to the inclined wall of the engagement nail | claw of a buckle part. Thus, the band is locked so as not to move in the return direction by the convex part getting over the engaging claw and the engaging surface of the convex part engaging with the locking wall of the engaging claw. Therefore, although the band can be easily inserted, once the band is inserted and the engagement tooth row and the engagement claw are engaged, the band can be fastened so as not to move in the return direction.

請求項４の発明によれば、バックル部の挿入孔の対向内面に可撓片を設け、それら各可撓片に表用係合爪と裏用係合爪をそれぞれ設け、可撓片の撓みにより、表用係合爪と裏用係合爪の先端間に確保されたバンド挿入通路を開くようにしているので、可撓片の撓みを利用して容易にバンドをバックル部に挿入し係止することができる。   According to invention of Claim 4, a flexible piece is provided in the opposing inner surface of the insertion hole of a buckle part, the front engaging claw and the back engaging claw are provided in each flexible piece, respectively, and bending of a flexible piece Therefore, the band insertion passage secured between the front engagement claws and the front engagement claws is opened so that the band can be easily inserted into the buckle using the bending of the flexible piece. Can be stopped.

請求項５の発明によれば、表用係合爪と裏用係合爪を、バンド挿入方向の前後方向に複数設けたので、強い係合力を発揮することができる。また、複数の係合爪があるから、耐久性の向上も図れる。   According to the invention of claim 5, since the front engaging claws and the back engaging claws are provided in the front-rear direction in the band inserting direction, a strong engaging force can be exerted. Moreover, since there are a plurality of engaging claws, durability can be improved.

即ち、バンド１２の表側Ａの係合歯列１５と裏側Ｂの係合歯列１６が半ピッチずれているから、表側の係合歯列１５がバックル部１０の表用係合爪２５と正しく係合しているとき、裏側の係合歯列１６は、バックル部１０の裏用係合爪２６に対して半ピッチずれた状態（半係合状態）にある。また、その状態から、バンド１２が半ピッチ分だけ移動すると、今度は、裏側の係合歯列１６がバックル部１０の裏用係合爪２６と正しく係合し、表側の係合歯列１５が、バックル部１０の表用係合爪２５に対して半ピッチずれた状態（半係合状態）となる。   That is, since the front side A engaging tooth row 15 and the back side B engaging tooth row 16 of the band 12 are shifted by a half pitch, the front side engaging tooth row 15 is correctly aligned with the front engaging claw 25 of the buckle portion 10. When engaged, the back side engaging tooth row 16 is in a state shifted from the back engaging claw 26 of the buckle portion 10 by a half pitch (half engaged state). In addition, when the band 12 moves from the state by a half pitch, the back side engagement tooth row 16 is correctly engaged with the back side engagement claw 26 of the buckle portion 10, and the front side engagement tooth row 15. However, it will be in the state (half-engaged state) which shifted | deviated half pitch with respect to the front engaging claw 25 of the buckle part 10. FIG.

このように、バンド１２の半ピッチ分の移動毎に、表側と裏側の係合歯列１５、１６及び係合爪２５、２６が交互に係合することになる。従って、半ピッチずつの細かい間隔で、バンド１２の締結長さを調節することができるようになる。   In this way, every time the band 12 moves by a half pitch, the front and back side engaging tooth rows 15 and 16 and the engaging claws 25 and 26 are alternately engaged. Therefore, the fastening length of the band 12 can be adjusted at fine intervals of half a pitch.

この場合、バンド１２の係合歯列１５、１６のピッチＨは、バンド１２の締結長さを調節する間隔の２倍に設定できるから、係合歯列１５、１６の歯（凸部１５ａ、１６ａ及び凹部１５ｂ、１６ｂ）の高さを特に小さくする必要がなく、また、表側Ａか裏側Ｂのいずれかは半係合状態にあるものの、反対側は正しい係合状態を維持できることになるので、十分な係合力を発揮することができ、締結強度が不足するおそれはない。   In this case, since the pitch H of the engagement tooth rows 15 and 16 of the band 12 can be set to twice the interval for adjusting the fastening length of the band 12, the teeth of the engagement tooth rows 15 and 16 (projections 15a, 16a and the recesses 15b, 16b) need not be particularly small, and either the front side A or the back side B is in a semi-engaged state, but the opposite side can maintain the correct engaged state. Sufficient engagement force can be exhibited and there is no fear that the fastening strength is insufficient.

また、図５の例と違い、バンド１２の左右でバランスが崩れることがないので、バンド１２に無用な捩れが起きる心配もなく、安定した係合状態を維持できる。   Further, unlike the example of FIG. 5, the balance is not lost on the left and right sides of the band 12, so that a stable engagement state can be maintained without worrying about unnecessary twisting of the band 12.

そのため、締結強度を弱めずに、細かい間隔で締結することが可能となり、ワイヤーハーネスを束ねる際の作業性の向上が図れる。また、細かい間隔で調節できることから、適切な締め付け力でワイヤーハーネスを束ねることができ、ワイヤーハーネスが馴染んできた際のズレ防止を図ることができる。   Therefore, it becomes possible to fasten with a fine space | interval, without weakening fastening strength, and the workability | operativity at the time of bundling a wire harness can be aimed at. Moreover, since it can adjust with a fine space | interval, a wire harness can be bundled with appropriate clamping force, and the shift | offset | difference at the time of the wire harness becoming familiar can be aimed at.

また、本実施形態の結束バンドＭ１では、バックル部１０の挿通孔１３にバンド１２の自由端側を挿入すると、バックル部１０の係合爪２５、２６の傾斜壁２５ｃ、２６ｃに対し係合歯列１５、１６の凸部１５ａ、１６ａの傾斜面１５ｃ、１６ｃが摺動することで、凸部１５ａ、１６ａが係合爪２５、２６を乗り越え、凸部１５ａ、１６ａの係合面１５ｄ、１６ｄと係合爪２５、２６の係止壁２５ｄ、２６ｄが係合することで、戻り方向に移動しないようにバンド１２が係止される。従って、バンド１２の挿入は容易にできるが、いったん挿入して係合歯列１５、１６と係合爪２５、２６が係合すると、確実に戻り方向に移動しないように、バンド１２を締結することができる。   Further, in the binding band M1 of the present embodiment, when the free end side of the band 12 is inserted into the insertion hole 13 of the buckle portion 10, the engagement teeth with respect to the inclined walls 25c and 26c of the engagement claws 25 and 26 of the buckle portion 10 are obtained. As the inclined surfaces 15c, 16c of the convex portions 15a, 16a of the rows 15, 16 slide, the convex portions 15a, 16a get over the engaging claws 25, 26, and the engaging surfaces 15d, 16d of the convex portions 15a, 16a. When the locking walls 25d and 26d of the engaging claws 25 and 26 are engaged, the band 12 is locked so as not to move in the return direction. Accordingly, although the band 12 can be easily inserted, once the band 12 is inserted and the engagement teeth 15 and 16 are engaged with the engagement claws 25 and 26, the band 12 is fastened so as not to move in the return direction. be able to.

また、本実施形態の結束バンドＭ１では、バックル部１０の挿通孔１３の対向内面に可撓片２１、２２を設け、それら各可撓片２１、２２に表用係合爪２５と裏用係合爪２６をそれぞれ設け、可撓片２１、２２の撓みにより、表用係合爪２５と裏用係合爪２６の先端間に確保されたバンド挿入通路１３ａを開くようにしているので、可撓片２１、２２の撓みを利用して容易にバンド１２をバックル部１０に挿入し係止することができる。また、表用係合爪２５と裏用係合爪２６を、バンド挿入方向Ｙの前後方向に複数設けているので、強い係合力を発揮することができるし、複数の係合爪が２５、２６あるから、耐久性の向上も図れる。   Moreover, in the binding band M1 of this embodiment, the flexible pieces 21 and 22 are provided on the opposing inner surface of the insertion hole 13 of the buckle portion 10, and the front engaging claws 25 and the back engagement members are provided on the flexible pieces 21 and 22, respectively. Since the claw 26 is provided, and the flexing pieces 21 and 22 are bent, the band insertion passage 13a secured between the front end of the front engaging claw 25 and the back engaging claw 26 is opened. The band 12 can be easily inserted into the buckle portion 10 and locked using the bending of the bending pieces 21 and 22. In addition, since the front engaging claws 25 and the back engaging claws 26 are provided in the front-rear direction of the band insertion direction Y, a strong engaging force can be exerted. Since there are 26, durability can be improved.
