Description

【０００１】
【発明の属する技術分野】
本発明は、環状になる部分で被保持物を保持するクランプに関する。
【０００２】
【従来の技術】
従来、環状になる部分で被保持物を保持するクランプとして、例えば実公平５−４２９７号公報に記載のものが知られている。このクランプによれば、クランプを電気機器のパネル面やプリント配線板上に取り付けて、そのクランプで複数のケーブル類を束ねて保持することにより、それら複数のケーブル類をパネル面やプリント配線板に沿った経路上に配線することができる。
【０００３】
【発明が解決しようとする課題】
ところで、上記公報に記載のクランプは、取付面に対する取り付けが容易で、しかも、取り付け後は取付面から容易には外れない構造になっているので、クランプの取付面からの脱落防止を重視する場合には、効果的なものである。
【０００４】
しかし、取付面となっている板材の表面側から操作するだけでは、クランプを取付面から取り外すことができず、クランプを取り外したい場合には、板材の裏面側に手をまわして弾性逆止片を弾性変形させる、といった面倒な操作が必要になる。また、このような取り外し作業を行うに当たって、板材の裏側に手を差し入れる十分な空間がない場合には、板材そのものを取り外してからクランプの取り外しを行う、といったさらに面倒な作業が必要になる。
【０００５】
そのため、例えば、製品の廃棄時にクランプを分別廃棄したり、あるいはクランプのリサイクルを行ったりしたい場合には、多大な手間をかけてクランプの取り外し作業を行わざるを得ない、という欠点があった。
本発明は、上記問題を解決するためになされたものであり、その目的は、取付面の表側での操作だけで取付面から容易に取り外し可能なクランプを提供することにある。
【０００６】
【課題を解決するための手段、および発明の効果】
上述の目的を達成するためになされた本発明のクランプは、
取付面上に固定されて、環状になる部分で被保持物を取り囲むことにより、前記被保持物を前記取付面の近傍に保持するクランプにおいて、
それぞれの一端が、変形可能なヒンジ部を介して連結された連結端、それぞれの他端が、前記ヒンジ部を変形させつつ相対的に変位可能な自由端となっていて、前記ヒンジ部を頂点として折り返すように連結された第１基部および第２基部と、
前記第２基部から前記第１基部のある側とは反対方向へ突出しており、前記取付面に穿設された取付穴に対し抜き挿し可能な複数の抜止部と、
前記第１基部から前記第２基部のある方向へ突出しており、前記ヒンジ部を変形させつつ前記第１基部を前記第２基部に対して相対的に変位させることにより、前記複数の抜止部の内側間に対し抜き挿し可能な挿入部と、
前記第１基部の自由端を基端部分として、当該基端部分から延出されたバンド部と、
前記バンド部の先端部分と、前記第１基部の連結端にある部分とを、互いに係合可能に構成してなり、係合させた際には、前記バンド部および前記第１基部によって前記環状になる部分が形成された状態となる第１の係合構造と、
前記第１基部の自由端にある部分と、前記第２基部の自由端にある部分とを、互いに係合可能に構成してなり、係合させた際には、前記第１基部の自由端が前記第２基部の自由端から離間するのを阻止する状態となる第２の係合構造とを備え、
前記複数の抜止部を前記取付穴に挿し込んでから、前記ヒンジ部を変形させつつ前記第１基部と前記第２基部とを折り重ねて前記抜止部の内側間に前記挿入部を挿し込むと、前記抜止部が外側へ変位して前記取付穴付近にある箇所に圧接または係合して前記取付穴から引き抜き不能な状態になり、その状態で前記第２の係合構造を係合させると、前記挿入部が前記抜止部の内側間から引き抜き不能な状態となることで、前記クランプが前記取付面上に固定される構造となっており、しかも、前記クランプが前記取付面上に固定された状態において前記第２の係合構造の係合を解除すると、前記挿入部が前記抜止部の内側間から引き抜き可能な状態となり、該挿入部を前記抜止部の内側間から引き抜くと、前記抜止部が内側へ変位可能になって前記取付穴から引き抜き可能な状態になることで、前記クランプが前記取付面上から取り外し可能となる
ことを特徴とする。
【０００７】
このクランプを形成する材料は、被保持物を保持した状態を維持できる程度の剛性と、抜止部や係合部分などバネのように機能する箇所が適切に弾性変形する程度の弾性とを有するものであれば、特に具体的には限定されないが、例えば合成樹脂材料を利用して成形したものが最も一般的である。
【０００８】
上記のように構成されるクランプは、複数の抜止部を取付穴に挿し込んで抜止部の内側間に挿入部を挿し込むと、抜止部が外側へ変位して取付穴付近にある箇所に圧接または係合して取付穴から引き抜き不能な状態になり、クランプを取付面にしっかりと固定することができる。また、この状態において、挿入部を抜止部の内側間から引き抜くと、抜止部が内側へ変位可能になって取付穴から引き抜き可能な状態になり、取付面側での操作を行うだけで、クランプを取付面から簡単に取り外すことができる。
【０００９】
したがって、クランプの取り外し作業に従来ほど手間がかからなくなり、クランプをリサイクル使用する場合、あるいは、クランプを分別廃棄する場合に便利である。
【００１１】
また、本発明のクランプにおいては、ヒンジ部を変形させて第１基部と第２基部とを折り重ねると、ちょうど挿入部が抜止部の内側間に挿入される。したがって、微妙な位置合わせをしなくても、ワンタッチ操作でクランプを取付面に固定することができる。
【００１３】
さらに、本発明のクランプにおいては、第１の係合構造を係合させると、バンド部が、第１基部の自由端側から第１基部の連結端側に架け渡されて、第１基部とともに環状となる部分を形成するので、この環状部分で被保持物を取り囲むことにより、被保持物を保持することができる。
【００１４】
また特に、第１の係合構造はヒンジ部側において係合するので、第１の係合構造の係合を解除する操作を行う場合に、仮に第１基部の連結端に引っ張るような力が作用したとしても、ヒンジ部が第１基部と第２基部との離間を防ぐので、誤って挿入部を引き抜いてしまう恐れがない。
【００１５】
加えて、本発明のクランプにおいては、第２の係合構造が係合することにより、第１基部と第２基部との離間を防ぐので、この第２の係合構造の係合を解除しない限り、誤って挿入部を引き抜いてしまう恐れがない。
【００１６】
なお、本発明のクランプは、
前記第２基部が、互いに係合または嵌合して一体になる第１，第２の分割体からなり、
前記抜止部が、前記第２基部の前記第１，第２の分割体からそれぞれ一つずつ延出され、
該二つの抜止部が変形可能な連結部を介して連結され、
該連結部を折り返すように変形させると前記二つの抜止部が重なる状態になり、その状態で前記第１，第２の分割体を一体にすると、前記二つの抜止部が、前記第２基部から前記第１基部のある側とは反対方向へ突出する状態になる
ものであってもよい。
【００１７】
このクランプにおいては、第２基部が、互いに係合または嵌合して一体になる第１，第２の分割体からなり、抜止部が、第１，第２の分割体からそれぞれ一つずつ延出されているので、全体を一体成形すると型抜きが困難になるような形状のクランプであっても、適当な箇所で第１，第２の分割体に分けることで容易に型抜き可能な形状とすることができる。
【００１８】
また、これら第１，第２の分割体は、抜止部および連結部を介して連結されることになるので、第２基部が分割されているにもかかわらず、一方の分割体を紛失するといったトラブルを防止することもできる。
また、本発明のクランプは、
前記第２基部が、互いに接近／離間可能な状態にある第１，第２の分割体からなり、
前記抜止部が、前記第２基部の前記第１，第２の分割体からそれぞれ一つずつ延出され、
該二つの抜止部が変形可能な連結部を介して連結されている
ものであってもよい。
【００１９】
このクランプにおいては、第２基部が、互いに接近／離間可能な状態にある第１，第２の分割体からなり、抜止部が、第１，第２の分割体からそれぞれ一つずつ延出されているので、２つの分割体を相対的に変位させて抜止部の内側間の間隔を狭めることができ、これにより、抜止部の取付穴に対する抜き差しをより容易に行うことができるようになる。
【００２０】
また、これら第１，第２の分割体は、抜止部および連結部を介して連結されることになるので、第２基部が分割されているにもかかわらず、一方の分割体を紛失するといったトラブルを防止することもできる。
【００２１】
【発明の実施の形態】
次に、本発明の実施形態について、いくつか具体例を挙げて説明する。
［第１実施形態］
図１（ａ）に示すように、クランプ１は、第１基部３および第２基部５を備えていて、これら第１基部３および第２基部５が、薄肉のヒンジ部７を頂点として折り返すように連結されている。
【００２２】
第１基部３の連結端（すなわち、ヒンジ部７側の端部）には、被係合部１１が突設されている。この被係合部１１は、第２基部５のある側とは反対方向へ突出していて、その側面には係止突起１１ａが突設されている。一方、第１基部３の自由端からはバンド部１３が延出され、このバンド部１３の自由端には係合部１５が設けられている。係合部１５には係合穴１５ａが形成され、この係合穴１５ａに上述の係止突起１１ａが嵌り込むことにより、係合部１５と被係合部１１が係合するようになっている。
【００２３】
これら係合部１５と被係合部１１とが係合すると、図１（ｂ）に示すように、第１基部３、バンド部１３、係合部１５、および被係合部１１が環状になり、この環状になる部分で被保持物（例えばケーブル束）を保持することができる。
また、第２基部５には、先割円筒体１７が設けられ、この先割円筒体１７が第２基部５の略中央から第１基部３のある側とは反対方向へ突出している。この先割円筒体１７は、図２（ａ）に示すように、先端部を丸めた略円柱状の突起１７ａの内部に穴１７ｂを穿設するとともに、突起１７ａの先端側から切り込み１７ｃを入れて縦割りしたものである。穴１７ｂは、入口部と最深部にそれぞれ奥へ進むほど狭くなるテーパが付与された形状で、また、切り込み１７ｃは、横断面十字状で、突起１７ａを４分割して４つの抜止部１７ｄを形成している。
【００２４】
一方、第１基部３には、挿入部１９が設けられ、この挿入部１９が第１基部の略中央から前記第２基部のある方向へ突出している。この挿入部１９は、図１（ｂ）に示すように、ヒンジ部７を変形させつつ第１基部３と第２基部５とを折り重ねると、ちょうど抜止部１７ｄの内側間（穴１７ｂ）に挿入されるような位置にある。
【００２５】
挿入部１９を抜止部１７ｄの内側間に挿入すると、図２（ｂ）に示すように、挿入部１９が４つの抜止部１７ｄを外側へ押し拡げ、各抜止部１７ｄが弾性変形し、その結果、先割円筒体１７の外径が拡大する。また、その状態で挿入部１９を抜止部１７ｄの内側間から抜去すると、各抜止部１７ｄの弾性変形が回復して、その結果、先割円筒体１７の外径が縮小する。
【００２６】
さらに、第１基部３には係合凹部２１が形成され、一方、第２基部５の自由端には係止片２３が突設され、図１（ｂ）に示すように、係止片２３の先端にある係止爪２３ａを係合凹部２１に引っかけることにより、第１基部３の自由端と第２基部５の自由端を互いに拘束するようになっている。
【００２７】
以上のように構成されたクランプ１によれば、クランプ１を取付面に固定するに当たっては、図１（ｂ）および図２（ｂ）に示すように、弾性変形前の先割円筒体１７の外径より大きくて弾性変形後の先割円筒体１７の外径より小さい取付穴Ｈを、事前に取付面となるパネルＰ（例えば、電子機器の筐体パネルやプリント配線板など）に穿設しておいて、その取付穴Ｈに先割円筒体１７を挿入した上で、挿入部１９を抜止部１７ｄの内側間に挿入すれば、各抜止部１７ｄが取付穴Ｈをなす壁面に圧接し、また、取付穴Ｈを貫通した部分の外径が取付穴Ｈの径よりも拡大して抜け止めとなり、その結果、先割円筒体１７が取付穴Ｈから引き抜き不能となって、クランプ１をパネルＰにしっかりと固定することができる。
【００２８】
また、このクランプ１を取付面から取り外すに当たっては、挿入部１９を抜止部１７ｄの内側間から抜去すれば、各抜止部１７ｄが取付穴Ｈをなす壁面に圧接しなくなり、また、取付穴Ｈを貫通した部分の外径が縮小して抜け止めとして機能しなくなり、その結果、先割円筒体１７が取付穴Ｈから引き抜き可能となって、クランプ１をパネルＰから簡単に取り外すことができる。よって、取り外しに従来品ほど手間がかからなくなり、クランプ１をリサイクル使用する場合、あるいは、クランプ１を分別廃棄する場合に便利である。
【００２９】
また、上記クランプ１によれば、ヒンジ部７を変形させて第１基部３と第２基部５とを折り重ねると、ちょうど挿入部１９が抜止部１７ｄの内側間（穴１７ｂ）に挿入されるので、微妙な位置合わせをしなくても、ワンタッチ操作でクランプ１をパネルＰに固定することができる。
【００３０】
さらに、上記クランプ１によれば、ヒンジ部７側に被係合部１１があるので、例えば、被係合部１１と係合部１５との係合を解除する操作を行う場合に、仮に被係合部１１に引っ張るような力が作用したとしても、ヒンジ部７が第１基部３と第２基部５との離間を防ぐので、誤って挿入部１９を引き抜いてしまう恐れがない。
【００３１】
また、第１基部３および第２基部５が、係合凹部２１と係止片２３とによって互いに係合する構造となっていて、仮にバンド部１３の付け根付近に引っ張るような力が作用したとしても、係合凹部２１および係止片２３が第１基部３と第２基部５との離間を防ぐので、やはり誤って挿入部１９を引き抜いてしまう恐れがない。
【００３２】
［第２実施形態］
図３に示すように、クランプ３１は、第１基部３３には挿入部３５だけを設け、第２基部３７の自由端からバンド部３９を延出した構造としてある。なお、上記クランプ１と同等の部分については、同じ符号を付すことにより、詳細な説明については省略する。
【００３３】
このようなクランプ３１でも、取付面側での操作を行うだけで、クランプ３１を取付面から簡単に取り外すことができるので、上記クランプ１と同様の効果があり、クランプ３１の取り外し作業に従来ほど手間がかからなくなり、クランプ３１をリサイクル使用する場合、あるいは、クランプ３１を分別廃棄する場合に便利である。
【００３４】
［第３実施形態］
図４および図５（ａ）に示すように、クランプ４１は、双方が嵌合して第２基部４３となる第１分割体４３ａおよび第２分割体４３ｂを備え、第１分割体４３ａから抜止部４５ａが延出され、第２分割体４３ｂから抜止部４５ｂが延出され、これら二つの抜止部４５ａ、４５ｂが、変形可能な帯状の連結部４７を介して連結されている。
【００３５】
第１分割体４３ａと第２分割体４３ｂは、図５（ｂ）に示すように、連結部４７を折り返すように変形させると嵌合させることができ、これに伴って二つの抜止部４５ａ、４５ｂが重なる位置にきて、第２基部４３から第１基部４９のある側とは反対方向へ突出する状態になる。この状態で抜止部４５ａ、４５ｂは、取付面に形成された取付穴に挿し込まれる。そして、ヒンジ部５１を変形させて第１基部４９と第２基部４３とを折り重ねると、ちょうど挿入部５３が抜止部４５ａ、４５ｂの内側間に挿入され、図５（ｃ）に示すように、抜止部４５ａ、４５ｂが弾性変形して外側へ拡がる。その結果、抜止部４５ａ、４５ｂは取付穴から引き抜けない状態になる。
【００３６】
このようなクランプ４１でも、取付面側での操作を行うだけで、クランプ４１を取付面から簡単に取り外すことができるので、クランプ４１の取り外し作業に従来ほど手間がかからなくなり、クランプ４１をリサイクル使用する場合、あるいは、クランプ４１を分別廃棄する場合に便利である。
【００３７】
また、このクランプ４１においては、第２基部４３が、互いに嵌合して一体になる第１分割体４３ａおよび第２分割体４３ｂからなり、抜止部４５ａ、４５ｂが、第１分割体４３ａおよび第２分割体４３ｂからそれぞれ一つずつ延出されているので、図５（ｂ）に示したような形状では、一体成形した時の型抜きが困難になるものの、図５（ａ）に示したように展開した形状であれば、容易に型抜きを行うことができる。
【００３８】
さらに、これら第１分割体４３ａおよび第２分割体４３ｂは、抜止部４５ａ、４５ｂ、および連結部４７を介して連結されることになるので、第２基部４３が２部品に分割されているにもかかわらず、一方の分割体を紛失するといったトラブルを防止することもできる。
【００３９】
［第４実施形態］
図６（ａ）および同図（ｂ）に示すように、クランプ６１は、第２基部６３が、互いに接近／離間可能な状態にある第１分割体６３ａおよび第２分割体６３ｂからなり、第１分割体６３ａから抜止部６５ａが延出され、第２分割体６３ｂから抜止部６５ｂが延出され、これら二つの抜止部６５ａ、６５ｂが、変形可能な帯状の連結部６７を介して連結されている。
【００４０】
このクランプ６１においては、第１分割体６３ａと第２分割体６３ｂとを容易に相対的に変位させることができるので、抜止部６５ａ、６５ｂ自体に触れることなく二つの抜止部６５ａ、６５ｂの内側間の間隔を狭める操作を行うことができる。したがって、抜止部６５ａ、６５ｂの内側間の間隔を最も狭めた状態にした上で取付穴に対する抜き差しを行うことができ、抜止部６５ａ、６５ｂの取付穴に対する抜き差しが容易になる。
【００４１】
また、これら第１分割体６３ａおよび第２分割体６３ｂは、抜止部６５ａ、６５ｂ、および連結部６７を介して連結されることになるので、第２基部６３が２部品に分割されているにもかかわらず、一方の分割体を紛失するといったトラブルを防止することもできる。
【００４２】
以上、本発明の実施形態について説明したが、本発明は上記の具体的な実施形態に限定されず、さらに種々の変更を加えた形態で実施することもできる。
例えば、上記第１実施形態のクランプ１は、係合凹部２１および係止片２３からなる係合構造、被係合部１１および係合部１５からなる係合構造について、特定の具体的な係合構造を例示したが、この種の係合構造の具体的な形態については任意であり、同等な機能を有する係合構造を適宜採用することができる。
【００４４】
加えて、上記クランプ１は、バンド部１３が部分的に薄肉とされて、その薄肉部分でのみ柔軟に湾曲するものとなっていたが、全体的に柔軟性のある帯状のバンド部を採用してもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a clamp that holds an object to be held at an annular portion.
[0002]
[Prior art]
Conventionally, a clamp described in Japanese Utility Model Publication No. 5-4297 is known as a clamp that holds an object to be held at an annular portion. According to this clamp, the clamp is mounted on the panel surface or printed wiring board of an electric device, and a plurality of cables are bundled and held by the clamp, whereby the plurality of cables are attached to the panel surface or the printed wiring board. It can be wired on the route along.
[0003]
[Problems to be solved by the invention]
By the way, the clamp described in the above publication is easy to mount on the mounting surface, and has a structure that is not easily detached from the mounting surface after mounting. Is an effective one.
[0004]
However, the clamp cannot be removed from the mounting surface simply by operating from the surface side of the plate that is the mounting surface. If you want to remove the clamp, turn your hand to the back side of the plate and check the elastic check piece. It is necessary to perform troublesome operations such as elastic deformation. Further, when performing such a removal operation, if there is not enough space for inserting a hand on the back side of the plate material, a more troublesome operation such as removing the clamp after removing the plate material itself becomes necessary.
[0005]
For this reason, for example, when it is desired to separate and discard the clamps at the time of disposal of the product or to recycle the clamps, there is a drawback in that the work for removing the clamps must be performed with great effort.
The present invention has been made to solve the above problems, and an object of the present invention is to provide a clamp that can be easily detached from the mounting surface only by an operation on the front side of the mounting surface.
[0006]
[Means for Solving the Problems and Effects of the Invention]
The clamp of the present invention made to achieve the above-mentioned object is
In a clamp that holds the object to be held in the vicinity of the mounting surface by surrounding the object to be held by a ring-shaped portion that is fixed on the mounting surface,
One end of each is connected via a deformable hinge, and the other end is a free end that can be relatively displaced while deforming the hinge. A first base and a second base connected to be folded as
A plurality of retaining portions projecting in a direction opposite to the side where the first base portion is provided from the second base portion, and capable of being inserted into and removed from a mounting hole formed in the mounting surface;
The plurality of retaining portions are protruded from the first base portion in a certain direction of the second base portion, and the first base portion is displaced relative to the second base portion while deforming the hinge portion. An insertion part that can be inserted into and removed from the inside ,
With the free end of the first base portion as a base end portion, a band portion extending from the base end portion;
The front end portion of the band portion and the portion at the connection end of the first base portion are configured to be engageable with each other, and when engaged, the annular portion is formed by the band portion and the first base portion. A first engagement structure in which a portion to be formed is formed;
The portion at the free end of the first base and the portion at the free end of the second base are configured to be engageable with each other, and when engaged, the free end of the first base And a second engagement structure that prevents the second base portion from separating from the free end of the second base portion ,
When the plurality of retaining portions are inserted into the mounting holes, the first base portion and the second base portion are folded while the hinge portion is deformed, and the inserting portion is inserted between the inner sides of the retaining portions. When the retaining portion is displaced to the outside and pressed or engaged with a place near the mounting hole, the pulling portion cannot be pulled out from the mounting hole, and in this state , the second engagement structure is engaged. The insertion portion is in a state in which it cannot be pulled out from the inside of the retaining portion, so that the clamp is fixed on the mounting surface, and the clamp is fixed on the mounting surface. When the engagement of the second engagement structure is released in a state where the insertion portion is released, the insertion portion can be pulled out from the inside of the retaining portion, and when the insertion portion is pulled out from the inside of the retaining portion, the retaining portion The part can be displaced inward Serial By become extractable state from the mounting hole, characterized in that the clamp is removable from the said mounting surface.
[0007]
The material forming this clamp has a rigidity that can maintain the state of holding the object to be held, and an elasticity that can appropriately elastically deform a portion that functions like a spring such as a retaining portion or an engaging portion. If it is, it will not specifically limit, but for example, what was shape | molded using the synthetic resin material is the most common.
[0008]
With the clamp configured as described above, when a plurality of retaining portions are inserted into the mounting holes, and the insertion portion is inserted between the inner sides of the retaining portions, the retaining portions are displaced outwardly and pressed against locations near the mounting holes. Alternatively, it can be engaged and cannot be pulled out from the mounting hole, and the clamp can be firmly fixed to the mounting surface. Also, in this state, if the insertion part is pulled out from the inside of the retaining part, the retaining part can be displaced inward and can be pulled out from the mounting hole. Can be easily removed from the mounting surface.
[0009]
Therefore, the work for removing the clamp is less time-consuming than before, and it is convenient when the clamp is recycled and used or when the clamp is separated and discarded .
[0011]
In the clamp of the present invention, when the hinge portion is deformed and the first base portion and the second base portion are folded over, the insertion portion is inserted between the inside of the retaining portion. Accordingly, the clamp can be fixed to the mounting surface by a one-touch operation without performing delicate positioning.
[0013]
Furthermore, in the clamp of the present invention, when engaging the first engagement structure, band portion, a bridged connection end side of the free end side or we first base portion of the first base, first base portion In addition, since the annular portion is formed, the object to be held can be held by surrounding the object to be held by the annular part.
[0014]
In particular, since the first engaging structure is Oite engages the hinge side, when performing an operation for releasing the engagement of the first engagement structure, such as if pulling the coupling end of the first base portion Even if a force is applied, the hinge portion prevents the first base portion and the second base portion from being separated from each other, so that there is no possibility that the insertion portion is pulled out by mistake.
[0015]
In addition, in the clamp of the present invention , the second engagement structure is engaged to prevent the first base portion and the second base portion from being separated from each other, so that the engagement of the second engagement structure is not released. As long as there is no risk of accidentally pulling out the insertion part.
[0016]
The clamp of the present invention is
The second base is composed of first and second divided bodies that are engaged with each other or fitted together, and
The retaining portions are extended one by one from the first and second divided bodies of the second base, respectively.
The two retaining portions are connected via a deformable connecting portion,
When the connecting portion is deformed so as to be folded back, the two retaining portions overlap each other. When the first and second divided bodies are integrated in this state, the two retaining portions are separated from the second base portion. It may be in a state of projecting in the opposite direction to the side on which the first base is located.
[0017]
In this clamp, the second base portion is composed of first and second divided bodies that are engaged with each other and fitted together, and the retaining portion extends from the first and second divided bodies one by one. Even if it is a clamp that has a shape that makes it difficult to die when the whole is integrally molded, it can be easily die-cut by dividing it into the first and second divided parts at appropriate locations. It can be.
[0018]

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with some specific examples.
[First Embodiment]
As shown in FIG. 1A, the clamp 1 includes a first base portion 3 and a second base portion 5 so that the first base portion 3 and the second base portion 5 are folded back with the thin hinge portion 7 as a vertex. It is connected to.
[0022]
An engaged portion 11 protrudes from the connection end of the first base portion 3 (that is, the end portion on the hinge portion 7 side). The engaged portion 11 protrudes in a direction opposite to the side on which the second base portion 5 is provided, and a locking projection 11a is provided on the side surface thereof. On the other hand, a band portion 13 extends from the free end of the first base portion 3, and an engaging portion 15 is provided at the free end of the band portion 13. An engaging hole 15a is formed in the engaging portion 15, and the engaging portion 15 and the engaged portion 11 are engaged with each other by fitting the locking protrusion 11a into the engaging hole 15a. Yes.
[0023]
When the engaging portion 15 and the engaged portion 11 are engaged, as shown in FIG. 1B, the first base portion 3, the band portion 13, the engaging portion 15, and the engaged portion 11 are annularly formed. Thus, an object to be held (for example, a cable bundle) can be held by the annular portion.
Further, the second base 5 is provided with a front-end cylindrical body 17, and the front-end cylindrical body 17 protrudes from the approximate center of the second base 5 in the direction opposite to the side where the first base 3 is located. As shown in FIG. 2A, the front-end cylindrical body 17 has a hole 17b formed in a substantially columnar projection 17a having a rounded tip, and a notch 17c is formed from the tip side of the projection 17a. It is divided vertically. The hole 17b has a shape in which a taper that becomes narrower toward the back is provided at each of the entrance portion and the deepest portion, and the notch 17c has a cross-shaped cross section, and the projection 17a is divided into four parts to form four retaining portions 17d. Forming.
[0024]
On the other hand, the first base portion 3 is provided with an insertion portion 19, and the insertion portion 19 protrudes from the approximate center of the first base portion in the direction in which the second base portion is located. As shown in FIG. 1 (b), when the first base portion 3 and the second base portion 5 are folded while the hinge portion 7 is deformed, the insertion portion 19 is inserted between the inside of the retaining portion 17d (hole 17b). It is in a position to be inserted.
[0025]
When the insertion portion 19 is inserted between the insides of the retaining portions 17d, as shown in FIG. 2 (b), the insertion portion 19 pushes the four retaining portions 17d outward, and each retaining portion 17d is elastically deformed. The outer diameter of the leading cylindrical body 17 is enlarged. Further, when the insertion portion 19 is removed from between the insides of the retaining portions 17d in that state, the elastic deformation of each retaining portion 17d is recovered, and as a result, the outer diameter of the leading cylindrical body 17 is reduced.
[0026]
Furthermore, an engagement recess 21 is formed in the first base 3, while a locking piece 23 projects from the free end of the second base 5, and as shown in FIG. The free end of the first base 3 and the free end of the second base 5 are constrained to each other by hooking the engaging claw 23a at the front end of the first base 3 into the engaging recess 21.
[0027]
According to the clamp 1 configured as described above, when the clamp 1 is fixed to the mounting surface, as shown in FIGS. 1 (b) and 2 (b), the front-end cylinder 17 before elastic deformation is deformed. A mounting hole H that is larger than the outer diameter and smaller than the outer diameter of the front-end cylindrical body 17 after elastic deformation is previously drilled in a panel P (for example, a housing panel or a printed wiring board of an electronic device) serving as a mounting surface. In addition, if the split cylindrical body 17 is inserted into the mounting hole H and then the insertion portion 19 is inserted between the inner sides of the retaining portions 17d, each retaining portion 17d is pressed against the wall surface forming the mounting hole H. In addition, the outer diameter of the portion that penetrates the mounting hole H is larger than the diameter of the mounting hole H to prevent it from coming off, and as a result, the leading cylindrical body 17 cannot be pulled out from the mounting hole H, and the clamp 1 is removed. It can be firmly fixed to the panel P.
[0028]
Further, when removing the clamp 1 from the mounting surface, if the insertion portion 19 is removed from between the insides of the retaining portions 17d, each retaining portion 17d does not come into pressure contact with the wall surface forming the mounting hole H. The outer diameter of the penetrating portion is reduced and does not function as a retainer. As a result, the leading cylindrical body 17 can be pulled out from the mounting hole H, and the clamp 1 can be easily detached from the panel P. Therefore, it is less time-consuming to remove than the conventional product, and it is convenient when the clamp 1 is recycled and used or when the clamp 1 is separated and discarded.
[0029]
Further, according to the clamp 1, when the hinge portion 7 is deformed and the first base portion 3 and the second base portion 5 are folded over, the insertion portion 19 is inserted between the inside of the retaining portion 17d (hole 17b). Therefore, the clamp 1 can be fixed to the panel P by a one-touch operation without performing delicate positioning.
[0030]
Furthermore, according to the clamp 1, since the engaged portion 11 is on the hinge portion 7 side, for example, when an operation of releasing the engagement between the engaged portion 11 and the engaging portion 15 is performed, Even if a pulling force is applied to the engaging portion 11, the hinge portion 7 prevents the first base portion 3 and the second base portion 5 from being separated from each other, so that there is no possibility that the insertion portion 19 is pulled out by mistake.
[0031]
Further, the first base 3 and the second base 5 are structured to engage with each other by the engaging recess 21 and the locking piece 23, and it is assumed that a force that pulls near the base of the band portion 13 acts. In addition, since the engaging recess 21 and the locking piece 23 prevent the first base 3 and the second base 5 from being separated from each other, there is no possibility that the insertion portion 19 is pulled out by mistake.
[0032]
[Second Embodiment]
As shown in FIG. 3, the clamp 31 has a structure in which only the insertion portion 35 is provided in the first base portion 33 and a band portion 39 is extended from the free end of the second base portion 37.
