Description

【0001】
【発明の属する技術分野】
本発明は、電線類や管類などを結束保持するためのバンド式保持具の技術分野に属する。
【0002】
【従来の技術】
電線類や管類などを結束するバンド式保持具であって、壁面などに固定されるベース部と、該ベース部に挿通されるバンド部とから構成され、前記バンド部は貫通孔及び嵌合爪を備える頭部と、複数個のバンド孔が該バンド部の挿通方向に列をなして設けられた帯部とからなり、前記貫通孔に前記帯部を貫通させて、前記バンド孔に前記嵌合爪を嵌挿させることによって構成される閉鎖環状のバンド式保持具がある。この種のバンド式保持具には、ベース部とバンド部とが一体のものと別体のもの(例えば米国特許第3632071号明細書や実公昭58−26556号公報に開示)とがある。
【0003】
【発明が解決しようとする課題】
ベース部とバンド部とが一体の場合、ベース部とバンド部との相対位置、すなわち結束された電線などとの相対位置が変化しないという利点がある反面、貫通孔及び嵌合爪を備える頭部の位置がほぼ決まっているので、狭い場所などでの作業性が良くないという欠点があった。一方、ベース部とバンド部とが別体であると、頭部の位置を自由に変更できるので狭い場所などでの作業性は良いが、結束時にバンド部が滑ったりして締め付け難いことがある。つまり一長一短であった。
【0004】
【課題を解決するための手段および発明の効果】
請求項1記載のバンド式保持具は、電線類や管類などを結束するバンド式保持具であって、壁面などに固定されるベース部と、該ベース部に挿通されるバンド部とから構成され、前記バンド部は貫通孔及び嵌合爪を備える頭部と、複数個のバンド孔が該バンド部の挿通方向に列をなして設けられた帯部とからなり、前記貫通孔に前記帯部を貫通させて、前記バンド孔に前記嵌合爪を嵌挿させることによって構成される閉鎖環状のバンド式保持具において、前記バンド部を前記ベース部に設けられた挿通孔と該挿通孔の内面に形成された係合突起に摺動挿通させるため、前記帯部の先端および該先端側のバンド孔間に凹部を設け、該先端の他端側のバンド孔間に前記係合突起と係合可能な係合部を設けたことを特徴とする。
【0005】
帯部の先端および先端側のバンド孔間に凹部を設けてあるので、バンド部を、ベース部に設けられた挿通孔と挿通孔の内面に形成された係合突起に摺動挿通させることができる。
また、先端の他端側のバンド孔間に係合突起と係合可能な係合部を設けているので、係合突起に係合部を係合させればベース部とバンド部とを一体化させてバンド部の位置を固定できるし、その係合をさせなければバンド部を挿通孔内で摺動させて相対位置を変化させることができる。すなわち、従来技術のバンド式保持具について述べた、ベース部とバンド部とが一体の場合の利点を採用することもできるし、ベース部とバンド部とが別体であるときの利点を採用することもできる。
【0006】
ベース部は壁面、床面、機器の筐体などに固定されるので、例えばネジまたはリベットなどの固定手段を使用するための穴等を設けておくとよい。或いは両面テープ等の接着又は粘着手段、又は一体成形されるファスナー、更に、両面粘着テープでマグネットをベース部に粘着し使うことにて壁面などに固定する手法を採用してもよい。
【0007】
用途、役割からして、ベース部は剛性のある材料を、バンド部は柔軟性かつ引っ張り強度のある材料を用いるのが望ましい。両者とも合成樹脂とすれば射出成形にて製造できるので、量産に適している。その場合、バンド部は エラストマー(ウレタン系、エステル系、オレフィン系、ポリアミド系など)、ポリエチレンなどを使用すると良い。
【0008】
請求項2記載のバンド式保持具は、請求項1記載のバンド式保持具において、前記ベース部には、差し込まれた前記帯部を前記ベース部と平行な方向に沿って前記挿通孔に誘導する平行誘導孔と、差し込まれた前記帯部を前記ベース部に対して傾斜した方向に沿って前記挿通孔に誘導する傾斜誘導孔とが設けられていることを特徴とする。
【0009】
平行誘導孔は、差し込まれた帯部をベース部と平行な方向(ベース部が固定されている壁面などに平行な方向)に沿って挿通孔に誘導し、傾斜誘導孔は、差し込まれた帯部をベース部に対して傾斜した方向(ベース部が固定されている壁面などに対して傾斜した方向)に沿って挿通孔に誘導するので、結束される電線類等の束径が例えばベース部からはみ出す程に大きい場合には平行誘導孔を、それよりも小さい場合には傾斜誘導孔を使用することで、それぞれ良好な結束状態にできる。
【0010】
請求項3記載のバンド式保持具は、請求項1または2記載のバンド式保持具において、前記バンド部の頭部には、前記帯部を挿通可能であるが一部が開放状態の余長処理孔が設けられている。
電線類等の束径が小さいときには、帯部を貫通孔に貫通させてバンド孔に嵌合爪を嵌合させることで、嵌合爪を閂として帯部が貫通孔から抜けるのを阻止して閉鎖環状として結束した際に、貫通孔から突出している帯部の先端側が長くなることがある。この余長をそのままにしておくと邪魔になる。また、この余長部分が邪魔になるからといって切り落としたのでは、例えば電線の本数が増えて束径が大きくなったときに対応できない。
【0011】
しかし、請求項3のバンド式保持具は、そのような余長部分をUターン状にして余長処理孔に通すことで、この部分が邪魔になるのを回避できる。また、余長処理孔は、一部が例えばスリット状に開放状態とされていて、これを利用して広げることができるから、余長部分を余長処理孔から抜き取るのも容易で、例えば電線の本数が増えて束径が大きくなったときにも対応できる。
【0012】
【発明の実施の形態】
次に、本発明の実施例により発明の実施の形態を説明する。
【0013】
【実施例】
本実施例のバンド式保持具100(図3参照)は、図1に示すバンド部10と図2に示すベース部50とによって構成される。
図1に示すとおり、バンド部10は頭部12と帯部14とからなる、TPU(ウレタン系エラストマー)の射出成形品である。
【0014】
頭部12には結束用の貫通孔13が設けられている。貫通孔13の穴形状は帯部14の断面形状に対応した略長方形であるが、寸法は帯部14の断面寸法をわずかに上回り、貫通孔13に帯部14を通して帯部14の長手方向に相対移動させることができる。
【0015】
この貫通孔13の縁部16は、一方の長辺の中央部が凹陥しており(凹陥していない部分がC字状で)、その凹陥部に嵌合爪15が立設されている。嵌合爪15の上半部は図1(b)に良好に示されるように湾曲しており、立設されている辺から反対側の辺上にわたって突き出ている。バンド部10がTPU製で、また縁部16と嵌合爪15との間に空隙17があることから、嵌合爪15はその基部を支点として、図1(b)に矢印で示す方向に沿って(時計回り、反時計回りに)弾性変形自在である。
【0016】
また、頭部12には、貫通孔13と並んで余長処理孔19が設けられている。この余長処理孔19の穴形状及びサイズは貫通孔13とほぼ同じであるが、貫通孔13とは反対側になる部分の中央部にスリット21が設けられていて、一部が開放状態になっている点で貫通孔13とは異なっている。従って、スリット21を挟む腕状部分23は自在に弾性変形できる。
【0017】
頭部12と一連になっている帯部14には、複数(本例では21個)のバンド孔25が帯部14の長手方向に沿う列をなして設けられており、それらの内の最も頭部12寄りのバンド孔25aは係合孔25aであり、その隣のバンド孔25との間に係合部27が設けられている。
【0018】
バンド孔25と係合孔25aとは、その開口寸法が同じであるが、帯部14の裏面14aではバンド孔25の間の部分及び末端のバンド孔25から帯部14の先端14bに至る部分が凹部29となっており、図1(c)においてバンド孔25の上下に位置するレール部31が相対的に高く(肉厚が大きく)なっている。
【0019】
ベース部50は図2に示すとおりの形状で、ポリアミドの射出成形品である。
略長方形の基板51の裏面51aは、壁面などの平面に密接可能とするために平面とされており、ボルトやビス等の固定手段を通すための円形の取付穴53が設けられている。また長方形の型抜穴55も設けられているが、これは射出成形時に抜き型で形成された穴である。
【0020】
基板51上には2つの凸部57、59が設けられており、それらの間には中央開口60が設けられている。
凸部57には上向きに開口する傾斜誘導孔61と横向きに開口する平行誘導孔63とが設けられている。傾斜誘導孔61及び平行誘導孔63は、共に凸部57と基板51との間に形成された挿通孔65に連通している。この挿通孔65の底面65aは基板51の裏面51aと平行な平面になっている。
【0021】
傾斜誘導孔61の案内面61aは図2(b)に示されるように傾斜しており(本実施例では底面65aに対して45度)、これに沿わせて帯部14を先端14bから挿し込むと帯部14は斜め方向から挿通孔65に入って行く。これに対して平行誘導孔63の底面となる部分は挿通孔65の底面65aと一連であるから、ここから帯部14を挿し込むと帯部14は底面65aと平行に挿通孔65に入って行く。
【0022】
また、凸部57の中央開口60に隣接する部分では、その下面(挿通孔65の天井となる面)が底面65a側に突出して係合突起67を形成している。このため、係合突起67によって挿通孔65の断面形状が凹字状にされている(凹字状部71)。図2(b)、(d)に良好に示されるとおり、係合突起67の平行誘導孔63側になる摺動部69では底面65aと対向する天井部は平坦であり、図2(d)に示すように、この部分では挿通孔65の断面形状はほぼ長方形である。
【0023】
摺動部69の寸法は、帯部14(凹部29が設けられていない部分、図1(d)参照)の断面寸法とほぼ整合している。一方、係合突起67の位置及び突出形状は帯部14の凹部29にほぼ整合しており、係合突起67が突出している凹字状部71の寸法は、帯部14の凹部29が設けられている部分(図1(f)参照)の断面寸法とほぼ整合している。
【0024】
従って、傾斜誘導孔61又は平行誘導孔63から帯部14を先端14bから挿し込んで挿通孔65に挿通させることができ、その際には帯部14は摺動部69を摺動する。また、凹字状部71では、凹部29が係合突起67を摺動し、レール部31が係合突起67の両脇を摺動する。
【0025】
底面65aは中央開口60の下方ほぼ全域にわたって延びて、型抜穴55まで達している。型抜穴55の上方には凸部59の下面73が配されているが、この下面73は底面65aと平行な平面で、底面65aの延長面との間隔は摺動部69の高さとほぼ等しい。
【0026】
凸部59の隣接する位置(中央開口60とは反対側)には、出口通路75が型抜穴55と連通して設けられている。出口通路75は基板51の上面で上向きに開口しており、その出口案内面75aは型抜穴55側が低くなる傾斜面である。なお、出口通路75は帯部14を挿通可能な寸法である。
【0027】
傾斜誘導孔61及び平行誘導孔63は挿通孔65に連通し、挿通孔65は中央開口60及び型抜穴55を介して出口通路75に連通しているので、図2(b)に示されるとおり、傾斜誘導孔61及び平行誘導孔63から出口通路75に至る一連の空間が形成されており、この空間に帯部14を通すことができる。
【0028】
次に、バンド式保持具100の使用方法を図3、図4により説明する。
使用に際しては、バンド部10の帯部14を、その先端14bから傾斜誘導孔61又は平行誘導孔63に挿し込んで挿通孔65に挿通させ、先端14b側を出口通路75から引き出しておく。このとき、ベース部50は設置場所となる壁面などに固定してあってもよいし、この後の適宜のタイミングで固定してもよい。
【0029】
帯部14を挿通孔65に挿通させた状態でも、係合部27が係合突起67よりも傾斜誘導孔61又は平行誘導孔63側にあるときは(図3(a)参照)、凹部29が係合突起67の下を通るので帯部14は係合突起67と干渉しない。このため、帯部14を挿通孔65内で自在に前後進させること、つまり頭部12側の突き出し長さ、先端14b側の引き出し長さを自在に調節できる。
【0030】
一方、先端14b側を引き出して行き、係合孔25aに隣接するバンド孔25が係合突起67の下を通過すると、このバンド孔25と係合孔25aとの間の係合部27が係合突起67に接触する。そのまま先端14b側をさらに引き出せば、係合部27が弾性変形しながら係合突起67の下を通過し、係合突起67が係合孔25aに嵌入して係合部27に係合突起67が係合する(図3(b)参照)。こうなると、頭部12側を引き出そうとしても係合突起67がそれを阻むので頭部12側を引き出すことができなくなる。また先端14b側をさらに引っ張っても、係合孔25aの頭部12側の部材27bを係合突起67の下に入り込ませなければならないから、その方向への移動も阻まれる。なお、無理矢理引っ張れば帯部14を移動させることも不可能ではないが、通常では帯部14の前後進は阻まれる。
【0031】
帯部14を前後進可能なままとするか係合突起67によって移動不能とするかはバンド式保持具100の設置場所(環境)や使用条件によって決めればよい。
また、帯部14を傾斜誘導孔61から挿し込むか平行誘導孔63から挿し込むかは、結束される電線類や管類などの束径に応じて、束径が小さければ傾斜誘導孔61を使用し大きければ平行誘導孔63を使用すればよい。また、例えばバンド式保持具100が取り付けられている壁面などとの関係で選択される頭部12の位置に応じて傾斜誘導孔61と平行誘導孔63とを使い分けてもよい。つまり、傾斜誘導孔61と平行誘導孔63とは、状況に応じて好ましい方を選んで使用すればよい。
【0032】
電線類や管類などの結束は、引き出してある先端14bを貫通孔13に通してバンド部10を環状にしてその中に電線類などを通して、或いは帯部14を電線類などに巻き付けるようにして先端14bを貫通孔13に通して環状として、いずれにしろ環状になっている中に電線類などが通された状態にしてから先端14b部分を持って引っ張れば、嵌合爪15が弾性変形して帯部14を通過させる。
【0033】
バンド部10は引っ張ると該引っ張り力に応じて3〜30%伸び、引っ張り力を解除すれば元の長さに戻ろうとする伸縮性を有する材料であるから、適度に締まったところで嵌合爪15をいずれかのバンド孔25に嵌合させれば、その先端部が縁部16に当接して閂状になるので結束が緩むことはない。この際、引っ張り力は解除されるがバンド部10には縮み方向の応力が残り、これが締め付け力とした作用し結束を良好にする。また、結束を解除する場合には、バンド部10を引き伸ばして嵌合爪15とバンド孔25との嵌合を緩めてから嵌合爪15をバンド孔25から抜けばよい。
【0034】
束径が小さくて帯部14の余長が長すぎるときは、この部分を折り返すようにして余長処理孔19に挿し込めばよい。そうすれば余長部分が邪魔になることはなくなる。
このように、本実施例のバンド式保持具100では、係合突起67と係合部27とを係合させればベース部50とバンド部10とを一体化させてバンド部10の位置を固定できるし、その係合をさせなければバンド部10を挿通孔65内で摺動させて相対位置を変化させることができる。すなわち、ベース部50とバンド部10とが一体の場合の利点を採用することもできるし、ベース部50とバンド部10とが別体であるときの利点を採用することもできる。
【0035】
また、バンド式保持具100は、結束される電線類等の束径が例えばベース部50からはみ出す程に大きい場合には平行誘導孔63を、それよりも小さい場合には傾斜誘導孔61を使用することで、それぞれ良好な結束状態にできる。また、頭部12の位置をどうするか等に応じて傾斜誘導孔61と平行誘導孔63とを使い分けることもできる。
【0036】
そして、電線類等の束径が小さいくて、帯部14の先端14b側に過剰な余長ができたときには、その余長部分をUターン状にして余長処理孔19に通すことで余長処理でき、余長部分が邪魔になるのを回避できる。また、余長処理孔19は、一部がスリット21となって開放されているので、これを利用して余長処理孔19を広げることができるから、余長部分を余長処理孔19から抜き取るのも容易で、例えば電線の本数が増えて束径が大きくなったときにも対応できる。
【0037】
以上、実施例に従って、本発明の実施の形態について説明したが、本発明はこのような実施例に限定されるものではなく、本発明の要旨を逸脱しない範囲でさまざまに実施できることは言うまでもない。

BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of a band-type holder for binding and holding electric wires and pipes.
[0002]
[Prior art]
A band-type holder for binding electric wires and pipes, etc., comprising a base part fixed to a wall surface and the like, and a band part inserted through the base part, the band part being fitted with a through hole and a fitting A head portion having a claw and a band portion in which a plurality of band holes are provided in a row in the insertion direction of the band portion, the band portion is passed through the through hole, and the band hole is There is a closed annular band-type holder configured by inserting a fitting claw. As this type of band-type holder, there are a base part and a band part which are integral and separate parts (for example, disclosed in US Pat. No. 3,632,071 and Japanese Utility Model Publication No. 58-26556).
[0003]
[Problems to be solved by the invention]
When the base part and the band part are integrated, there is an advantage that the relative position between the base part and the band part, that is, the relative position with a bundled electric wire or the like does not change, but the head having a through hole and a fitting claw Since the position of is almost fixed, there is a disadvantage that workability in a narrow place is not good. On the other hand, if the base part and the band part are separate, the position of the head can be freely changed, so the workability in a narrow place is good, but the band part may slide and difficult to tighten during binding . In other words, it was both pros and cons.
[0004]
[Means for Solving the Problems and Effects of the Invention]
The band-type holder according to claim 1 is a band-type holder for binding electric wires, pipes, and the like, and includes a base portion fixed to a wall surface and the like, and a band portion inserted through the base portion. The band portion includes a head portion having a through hole and a fitting claw, and a band portion in which a plurality of band holes are provided in a row in the insertion direction of the band portion. In a closed annular band-type holder constructed by inserting the fitting claw into the band hole through the portion, the band portion is provided with an insertion hole provided in the base portion and the insertion hole. In order to slide the insertion protrusion formed on the inner surface, a recess is provided between the tip of the band portion and the band hole on the tip end side, and the engagement protrusion is engaged with the band hole on the other end side of the tip end. The engaging part which can be combined is provided.
[0005]
Since the recess is provided between the tip of the band part and the band hole on the tip side, the band part can be slid through the insertion hole provided in the base part and the engagement protrusion formed on the inner surface of the insertion hole. it can.
In addition, since an engaging portion that can engage with the engaging protrusion is provided between the band holes on the other end side of the tip, the base portion and the band portion are integrated when the engaging portion is engaged with the engaging protrusion. The position of the band portion can be fixed and the relative position can be changed by sliding the band portion within the insertion hole if the band portion is not engaged. That is, it is possible to adopt the advantages in the case where the base portion and the band portion are integrated as described in the related art band-type holder, or the advantages when the base portion and the band portion are separate. You can also.
[0006]
Since the base portion is fixed to a wall surface, a floor surface, a housing of the device, or the like, for example, a hole for using a fixing means such as a screw or a rivet may be provided. Alternatively, an adhesive or adhesive means such as a double-sided tape, or an integrally formed fastener, and a method of fixing the magnet to the base portion by using the double-sided adhesive tape and adhering it to the base portion may be adopted.
[0007]
It is desirable to use a rigid material for the base portion and a flexible and tensile strength material for the band portion, depending on the application and role. Since both can be manufactured by injection molding if they are made of synthetic resin, they are suitable for mass production. In that case, it is preferable to use an elastomer (urethane type, ester type, olefin type, polyamide type, etc.), polyethylene or the like for the band part.
[0008]
The band-type holder according to claim 2 is the band-type holder according to claim 1, wherein the band portion inserted into the base portion is guided to the insertion hole along a direction parallel to the base portion. And a parallel guide hole and an inclined guide hole for guiding the inserted band part to the insertion hole along a direction inclined with respect to the base part.
[0009]
The parallel guide hole guides the inserted band part to the insertion hole along the direction parallel to the base part (direction parallel to the wall surface to which the base part is fixed), and the inclined guide hole is inserted into the band. Since the guide portion is guided to the insertion hole along the direction inclined with respect to the base portion (the direction inclined with respect to the wall surface or the like to which the base portion is fixed), the bundle diameter of the electric wires to be bound is, for example, the base portion When it is large enough to protrude from the parallel guide hole, when it is smaller than that, an inclined guide hole is used, so that a good bundling state can be achieved.
[0010]
The band-type holder according to claim 3 is the band-type holder according to claim 1 or 2, wherein the band portion can be inserted through the head portion of the band portion, but a part of the band-type holder is open. Processing holes are provided.
When the bundle diameter of electric wires, etc. is small, by passing the band part through the through hole and fitting the fitting claw into the band hole, the band part is prevented from coming out of the through hole using the fitting claw as a trough. When bundled as a closed ring, the leading end side of the belt portion protruding from the through hole may be long. If this extra length is left as it is, it will be in the way. Further, if the extra length portion is obstructed, it is not possible to cope with the case where the bundle diameter is increased by increasing the number of wires.
[0011]
However, the band-type holder according to claim 3 can avoid such a portion from being obstructed by making such a surplus portion into a U-turn shape and passing it through the surplus length processing hole. Further, since the surplus length processing hole is partially opened in a slit shape, for example, and can be expanded using this, it is easy to remove the surplus length portion from the surplus length processing hole. It is possible to cope with the increase in the bundle diameter due to an increase in the number of slabs.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described by way of examples of the present invention.
[0013]
【Example】
The band-type holder 100 (see FIG. 3) of the present embodiment is configured by the band portion 10 shown in FIG. 1 and the base portion 50 shown in FIG.
As shown in FIG. 1, the band portion 10 is a TPU (urethane elastomer) injection-molded product composed of a head portion 12 and a belt portion 14.
[0014]
The head 12 is provided with a through hole 13 for bundling. The hole shape of the through-hole 13 is a substantially rectangular shape corresponding to the cross-sectional shape of the band part 14, but the dimension is slightly larger than the cross-sectional dimension of the band part 14, and passes through the band part 14 through the through-hole 13 in the longitudinal direction of the band part 14. It can be moved relative.
[0015]
The edge 16 of the through-hole 13 has a concave portion at the center of one long side (the non-recessed portion is C-shaped), and a fitting claw 15 is erected in the recessed portion. The upper half of the fitting claw 15 is curved as shown in FIG. 1 (b), and protrudes from the side that is erected on the opposite side. Since the band portion 10 is made of TPU and there is a gap 17 between the edge portion 16 and the fitting claw 15, the fitting claw 15 has its base as a fulcrum in the direction indicated by the arrow in FIG. Elastically deformable along (clockwise and counterclockwise).
[0016]
Further, the head 12 is provided with a surplus length processing hole 19 along with the through hole 13. Although the hole shape and size of the extra length treatment hole 19 are substantially the same as those of the through hole 13, a slit 21 is provided in the central portion of the portion opposite to the through hole 13, and a part thereof is in an open state. This is different from the through-hole 13. Accordingly, the arm-like portion 23 sandwiching the slit 21 can be freely elastically deformed.
[0017]
A plurality of (21 in this example) band holes 25 are provided in a line along the longitudinal direction of the band part 14 in the band part 14 in series with the head part 12. The band hole 25a near the head 12 is an engagement hole 25a, and an engagement portion 27 is provided between the band hole 25 adjacent to the band hole 25a.
[0018]
The band hole 25 and the engagement hole 25a have the same opening size, but on the back surface 14a of the band part 14, the part between the band holes 25 and the part from the band band 25 at the end to the tip 14b of the band part 14 Is a concave portion 29, and the rail portions 31 located above and below the band hole 25 in FIG. 1C are relatively high (thickness is large).
[0019]
The base portion 50 has a shape as shown in FIG. 2 and is a polyamide injection-molded product.
The back surface 51a of the substantially rectangular substrate 51 is a flat surface so that it can be brought into close contact with a flat surface such as a wall surface, and is provided with a circular mounting hole 53 for passing a fixing means such as a bolt or a screw. In addition, a rectangular die punching hole 55 is also provided, which is a hole formed by a punching die at the time of injection molding.
[0020]
Two convex portions 57 and 59 are provided on the substrate 51, and a central opening 60 is provided between them.
The convex portion 57 is provided with an inclined guide hole 61 that opens upward and a parallel guide hole 63 that opens sideways. Both the tilt guide hole 61 and the parallel guide hole 63 communicate with an insertion hole 65 formed between the convex portion 57 and the substrate 51. The bottom surface 65 a of the insertion hole 65 is a plane parallel to the back surface 51 a of the substrate 51.
[0021]
The guide surface 61a of the tilt guide hole 61 is tilted as shown in FIG. 2B (45 degrees with respect to the bottom surface 65a in this embodiment), and the belt portion 14 is inserted from the tip 14b along this direction. When inserted, the belt portion 14 enters the insertion hole 65 from an oblique direction. On the other hand, since the part which becomes the bottom face of the parallel guide hole 63 is a series with the bottom face 65a of the insertion hole 65, when the band part 14 is inserted from here, the band part 14 enters the insertion hole 65 parallel to the bottom face 65a. go.
[0022]
Moreover, in the part adjacent to the center opening 60 of the convex part 57, the lower surface (surface used as the ceiling of the penetration hole 65) protrudes in the bottom face 65a side, and the engagement protrusion 67 is formed. For this reason, the cross-sectional shape of the insertion hole 65 is made concave by the engaging protrusion 67 (concave portion 71). As shown well in FIGS. 2B and 2D, in the sliding portion 69 on the parallel guide hole 63 side of the engaging protrusion 67, the ceiling portion facing the bottom surface 65a is flat, and FIG. As shown, the cross-sectional shape of the insertion hole 65 is substantially rectangular in this portion.
[0023]
The dimension of the sliding part 69 is substantially matched with the cross-sectional dimension of the band part 14 (the part where the concave portion 29 is not provided, see FIG. 1D). On the other hand, the position and protruding shape of the engaging protrusion 67 are substantially aligned with the concave portion 29 of the band portion 14, and the dimension of the concave portion 71 from which the engaging protrusion 67 protrudes is provided by the concave portion 29 of the band portion 14. The cross-sectional dimension of the portion (see FIG. 1 (f)) is substantially matched.
[0024]
Accordingly, the band portion 14 can be inserted from the tip 14 b through the inclined guide hole 61 or the parallel guide hole 63 and can be inserted into the insertion hole 65, and at this time, the band portion 14 slides on the sliding portion 69. Further, in the concave portion 71, the concave portion 29 slides on the engaging protrusion 67, and the rail portion 31 slides on both sides of the engaging protrusion 67.
[0025]
The bottom surface 65 a extends over substantially the entire area below the central opening 60 and reaches the die punching hole 55. The lower surface 73 of the convex portion 59 is disposed above the die punching hole 55. The lower surface 73 is a plane parallel to the bottom surface 65a, and the distance from the extended surface of the bottom surface 65a is substantially equal to the height of the sliding portion 69. equal.
[0026]
An exit passage 75 is provided in communication with the die punching hole 55 at a position adjacent to the convex portion 59 (on the side opposite to the central opening 60). The outlet passage 75 opens upward on the upper surface of the substrate 51, and the outlet guide surface 75a is an inclined surface that becomes lower on the mold punching hole 55 side. The outlet passage 75 has a dimension that allows the band portion 14 to be inserted.
[0027]
The inclined guide hole 61 and the parallel guide hole 63 communicate with the insertion hole 65, and the insertion hole 65 communicates with the outlet passage 75 via the central opening 60 and the mold punching hole 55, and is shown in FIG. As described above, a series of spaces from the inclined guide holes 61 and the parallel guide holes 63 to the outlet passage 75 are formed, and the band portion 14 can be passed through this space.
[0028]
Next, a method of using the band-type holder 100 will be described with reference to FIGS.
In use, the band portion 14 of the band portion 10 is inserted into the inclined guide hole 61 or the parallel guide hole 63 from the tip 14 b and inserted through the insertion hole 65, and the tip 14 b side is pulled out from the outlet passage 75. At this time, the base unit 50 may be fixed to a wall surface or the like as an installation place, or may be fixed at an appropriate timing thereafter.
[0029]
Even when the band portion 14 is inserted into the insertion hole 65, when the engaging portion 27 is located closer to the inclined guiding hole 61 or the parallel guiding hole 63 than the engaging protrusion 67 (see FIG. 3A), the recess 29 Passes under the engaging protrusion 67, so that the band portion 14 does not interfere with the engaging protrusion 67. For this reason, the belt | band | zone part 14 can be freely advanced back and forth within the insertion hole 65, ie, the protrusion length by the side of the head 12, and the drawing length by the side of the front-end | tip 14b can be adjusted freely.
[0030]
On the other hand, when the band hole 25 adjacent to the engagement hole 25a passes under the engagement protrusion 67 by pulling out the tip 14b side, the engagement portion 27 between the band hole 25 and the engagement hole 25a is engaged. Contact the mating protrusion 67. If the tip 14b side is further pulled out as it is, the engaging portion 27 passes under the engaging protrusion 67 while being elastically deformed, and the engaging protrusion 67 is fitted into the engaging hole 25a and is engaged with the engaging portion 27. Engage (see FIG. 3B). In this case, even if it is attempted to pull out the head 12 side, the engaging projection 67 prevents the head 12 from being pulled out. Further, even if the tip 14b side is further pulled, the member 27b on the head 12 side of the engagement hole 25a must be inserted under the engagement protrusion 67, so that movement in that direction is also prevented. Note that it is not impossible to move the belt portion 14 by forcibly pulling it, but the forward and backward movement of the belt portion 14 is normally prevented.
[0031]
Whether the band portion 14 can be moved forward and backward or cannot be moved by the engaging protrusion 67 may be determined depending on the installation location (environment) of the band-type holder 100 and use conditions.
Further, whether the band portion 14 is inserted from the inclined guide hole 61 or the parallel guide hole 63 depends on the bundle diameter of the electric wires and tubes to be bound if the bundle diameter is small. If it is large, the parallel guide hole 63 may be used. In addition, for example, the inclined guide hole 61 and the parallel guide hole 63 may be selectively used according to the position of the head 12 selected in relation to the wall surface to which the band-type holder 100 is attached. That is, the inclined guide hole 61 and the parallel guide hole 63 may be selected and used according to the situation.
[0032]
For binding of electric wires and pipes, the leading end 14b drawn out is passed through the through-hole 13 so that the band portion 10 is formed into an annular shape, and the electric wires are passed through the band portion 10 or the band portion 14 is wound around the electric wires. If the tip 14b is passed through the through-hole 13 in an annular shape, and the wires 14 are passed through the annular shape anyway and then pulled with the tip 14b portion, the fitting claw 15 is elastically deformed. And let the belt part 14 pass.
[0033]
The band portion 10 is a stretchable material that stretches by 3 to 30% according to the pulling force when it is pulled and returns to its original length when the pulling force is released. Is fitted into any one of the band holes 25, the tip thereof comes into contact with the edge 16 to form a hook shape, so that the binding is not loosened. At this time, the tensile force is released, but the stress in the contraction direction remains in the band portion 10, which acts as a tightening force to improve the binding. Further, when releasing the binding, the band portion 10 may be stretched to loosen the fitting claw 15 and the band hole 25 and then the fitting claw 15 may be removed from the band hole 25.
[0034]
When the bundle diameter is small and the extra length of the band portion 14 is too long, it may be inserted into the extra length processing hole 19 so that this portion is folded. Then the extra length will not get in the way.
As described above, in the band-type holder 100 of the present embodiment, when the engagement protrusion 67 and the engagement portion 27 are engaged, the base portion 50 and the band portion 10 are integrated to position the band portion 10. The band portion 10 can be slid in the insertion hole 65 and the relative position can be changed if the engagement is not performed. That is, the advantage in the case where the base part 50 and the band part 10 are integrated can be adopted, and the advantage in the case where the base part 50 and the band part 10 are separate can also be adopted.
[0035]
In addition, the band-type holder 100 uses the parallel guide hole 63 when the bundle diameter of the electric wires to be bound is so large as to protrude from the base portion 50, for example, and the inclined guide hole 61 when the bundle diameter is smaller than that. By doing so, each can be in a good binding state. Further, the inclined guide hole 61 and the parallel guide hole 63 can be properly used depending on the position of the head 12 or the like.
[0036]
When the bundle diameter of the wires and the like is small and an excessive surplus length is formed on the end 14b side of the band portion 14, the surplus length portion is formed in a U-turn shape and passed through the surplus length processing hole 19. Long processing can be performed, and the extra length can be prevented from getting in the way. In addition, since the surplus length processing hole 19 is partially opened as a slit 21, the surplus length processing hole 19 can be widened using this, so that the surplus length portion is removed from the surplus length processing hole 19. It is easy to pull out, for example, when the number of wires is increased and the bundle diameter is increased.
