Description

本発明は、電線やプリント基板等のような対象物を、パネルやシャーシ等の被取付部材に固定することができると共に、前記被取付部材からの取り外しを容易に行うことができる固定具に関する。   The present invention relates to a fixture that can fix an object such as an electric wire or a printed circuit board to a member to be attached such as a panel or a chassis and can be easily detached from the member to be attached.

従来から、電線やプリント基板等のような対象物を、パネルやハウジング等の被取付部材に固定するため、様々な固定具が使用されている。例えば、自動販売機等の各種機器においては、内部の電線や配管等(以下、「線材」と総称することがある)の中間部を、シャーシやパネル等の被取付部材に固定することが通常行われている。そして、近年では、このような固定具には、被取付部材からの取り外しを容易に行うための工夫がなされている。   Conventionally, various fixtures are used to fix an object such as an electric wire or a printed circuit board to a member to be attached such as a panel or a housing. For example, in various devices such as vending machines, it is usual to fix an intermediate portion of an internal electric wire, piping or the like (hereinafter sometimes collectively referred to as “wire”) to a member to be attached such as a chassis or a panel. Has been done. In recent years, such fixtures have been devised for easy removal from the attached member.

このような固定具としては、例えば、被取付部材の取付孔に挿入され、自身を該取付孔に着脱自在に取り付ける挿入部を、本体部材に備えたものがある。前記挿入部は、前記本体部材の一端部より下方へ突設された支柱部と、該支柱部の下端部に弾性を有する屈曲可能な接続部を介して接続され、斜め上方に延出する折り返し部とを備えている。そして、前記支柱部及び折り返し部の外側面には、前記取付孔の周縁部に係止する係止部が各々設けられており、該折り返し部の係止部より上部側の位置には、前記被取付部材の上部にて外方向に延出するレバー部が形成されている。このレバー部は操作部を有し、当該操作部を押圧することで、前記挿入部が縮小変形し、前記固定具は、前記被取付部材の取付孔から簡単に取外すことができる。(例えば、特許文献1参照)。   As such a fixture, for example, there is one in which a main body member is provided with an insertion portion that is inserted into an attachment hole of a member to be attached, and is detachably attached to the attachment hole. The insertion portion is connected to a column portion projecting downward from one end portion of the main body member and a lower end portion of the column portion via an elastic bendable connection portion, and is folded back and extends obliquely upward. Department. And the latching | locking part latched to the peripheral part of the said mounting hole is each provided in the outer surface of the said support | pillar part and the folding | returning part, The position above the latching | locking part of this folding | returning part has the said A lever portion extending outward is formed at the upper portion of the attached member. This lever part has an operation part, and when the operation part is pressed, the insertion part is reduced and deformed, and the fixture can be easily removed from the attachment hole of the attached member. (For example, refer to Patent Document 1).

また、線材をバンド部と、このバンド部の基端に連設され、バンド挿通孔を有するバックル部と、このバックル部に一体に突設され、取付パネルの取付孔に挿入される矢形状の係止脚部を備えた固定具も紹介されている。前記矢形状の係止脚部は、前記バックル部から垂設された支柱の先端からバックル部に向けて折り返し状に形成された一対の拡縮変形自在な可動係止片を有し、各可動係止片の中途部には、取付パネルの取付孔と抜止め状に係合する係合段部が設けられている。そして、各可動係止片の自由端側には、押圧操作片と安定脚片が形成されている。この固定具は、前記押圧操作片を互いに近づける方向に押圧することで、前記可動係止片を縮小変形し、前記取付パネルから簡単に取外すことができる。(例えば、特許文献2参照)。   Further, the wire rod is connected to the band portion, the base end of the band portion, the buckle portion having the band insertion hole, and the arrow-shaped shape that is integrally projected to the buckle portion and inserted into the mounting hole of the mounting panel. Fixtures with locking legs are also introduced. Each of the arrow-shaped locking legs has a pair of movable locking pieces that can be expanded and contracted and formed in a folded shape from the tip of a column suspended from the buckle toward the buckle.

しかしながら、前述した特許文献1に記載された固定具の挿入部は、支柱部と当該支柱部に接続された弾性変形可能な1つの折り返し部とから構成されており、操作部によって、この折り返し部を支柱部に向けて近づけることで縮小変形させ、被取付部材の取付孔から取外す構成を備えている。このため、折り返し部の支柱部に対する縮小変形のレンジ(範囲)を大きくとる必要がある。したがって、折り返し部と支柱部との接続部に大きな負荷がかかる虞がある。また、操作部は、挿入部の片側にのみ設けられているため、使用者の指で操作する際に摘み難く、バランスの取れた安定した取外し作業を行うことが困難になる虞もある。   However, the insertion portion of the fixture described in Patent Document 1 described above is composed of a column portion and one elastically deformable folded portion connected to the column portion, and the folded portion is operated by the operation unit. It has a configuration in which it is reduced and deformed by approaching it toward the support column and is removed from the mounting hole of the mounted member. For this reason, it is necessary to increase the range (range) of the reduction deformation with respect to the support portion of the folded portion. Therefore, there is a possibility that a large load is applied to the connection portion between the folded portion and the column portion. Moreover, since the operation part is provided only on one side of the insertion part, it is difficult to pick when operating with the finger of the user, and there is a possibility that it is difficult to perform a balanced and stable removal operation.

また、前述した特許文献2及び特許文献3に記載された固定具は、安定脚片と係止脚部によって取付パネルや基板を挟持することで、これらに安定して固定されるが、この時、取付パネルや基板の厚さに応じて安定脚片が弾性変形することで、取付パネルや基板の厚さの違いを許容している。しかしながら、特許文献2及び特許文献3に記載された固定具は、前記押圧操作片が安定脚片に設けられているため、取付パネルや基板の厚さによって安定脚片が変形すると、当該押圧操作片を操作するために必要な力が変わるという欠点がある。   In addition, the fixing devices described in Patent Document 2 and Patent Document 3 described above are stably fixed to these by holding the mounting panel and the substrate with the stable leg pieces and the locking leg portions. The stable leg piece is elastically deformed according to the thickness of the mounting panel or the substrate, thereby allowing a difference in the thickness of the mounting panel or the substrate. However, in the fixtures described in Patent Literature 2 and Patent Literature 3, since the pressing operation piece is provided on the stable leg piece, if the stable leg piece is deformed due to the thickness of the mounting panel or the substrate, the pressing operation piece There is a disadvantage that the force required to operate the piece changes.

本発明は、このような従来の固定具を改良することを目的とするものであり、被取付部材の厚さに影響されることなく、常に一定の操作力を付与することによって、被取付部材から取外すことが可能であると共に、押圧操作部の操作性が向上した固定具を提供することを目的とする。   The present invention aims to improve such a conventional fixture, and by always giving a constant operating force without being affected by the thickness of the mounted member, the mounted member An object of the present invention is to provide a fixing tool that can be detached from the press and has improved operability of the pressing operation portion.

この目的を達成するため、本発明は、挿入された対象物を保持する保持部と、前記保持部に設けられ且つ被取付部材の取付孔に挿入されて当該被取付部材の一方の面に係止される係止部と、前記保持部に設けられ且つ前記被取付部材の他方の面に当接する当接部と、を備え、前記係止部と当接部とによって前記被取付部材を挟持する固定具であって、前記係止部は、前記取付孔を画定する壁面に当接した際に、当該取付孔の略中心方向に向けて縮小変形して当該取付孔に挿入され、前記当接から解放された際に弾性復元して前記被取付部材の一方の面に係止されてなり、前記係止部には、当該係止部を両側から押圧して前記縮小変形を行なわせ、当該係止部を前記取付孔から取外し可能な状態にする一対の押圧操作部が設けられ、前記一対の押圧操作部は、前記係止部を前記取付孔に挿入した際に、前記被取付部材の他方の面の上方にて外方向に延出してなり、前記当接部は、前記被取付部材の他方の面に当接する一対の当接片を有しており、前記一対の押圧操作部の一方及び前記一対の当接片の一方は前記係止部の両側の一方に配置されると共に、前記一対の押圧操作部の他方及び前記一対の当接片の他方は前記係止部の両側の他方に配置され、前記一対の押圧操作部は点対称となるように互いに略180度位相して設けられると共に、前記一対の当接片は点対称となるように互いに略180度位相して設けられ、前記一対の押圧操作部と前記一対の当接片とは、前記被取付部材の他方の面から見て、互い違いに配置される、構成を備えた固定具を提供するものである。 In order to achieve this object, the present invention relates to a holding portion that holds an inserted object, and a holding portion that is provided in the holding portion and is inserted into a mounting hole of the mounted member and is engaged with one surface of the mounted member. A locking portion that is stopped, and a contact portion that is provided on the holding portion and contacts the other surface of the mounted member, and the mounted member is sandwiched between the locking portion and the contacting portion. When the locking portion comes into contact with a wall surface defining the mounting hole, the locking portion is reduced and deformed toward a substantially central direction of the mounting hole, and is inserted into the mounting hole. It is elastically restored when released from contact and is locked to one surface of the mounted member, and the locking portion is pressed from both sides to cause the reduction deformation, A pair of pressing operation parts for making the locking part detachable from the mounting hole is provided, Pressure operating section, the locking portion when inserted into the mounting hole, Ri Na extending outwardly at the upper of the other surface of the member being attached, the abutment, the mounted member One of the pair of pressing operation parts and one of the pair of contact pieces are arranged on one of both sides of the locking part, and The other of the pair of pressing operation parts and the other of the pair of abutting pieces are disposed on the other side of the locking part, and the pair of pressing operation parts are phased approximately 180 degrees so as to be point-symmetric. The pair of contact pieces are provided in phase with each other so as to be point-symmetric with respect to each other, and the pair of pressing operation portions and the pair of contact pieces are the other of the attached members. It is intended to provide a fixture having a configuration that is alternately arranged when viewed from the surface .

この構成を備えた固定具は、係止部に押圧操作部が設けられており、当接部には設けられていないため、被取付部材の厚さに応じて当接部が弾性変形したとしても、この弾性変形が前記押圧操作部に影響を与えることがない。したがって、本発明にかかる固定具を被取付部材から取外す際には、押圧操作部を常に一定の操作力で押圧すればよく、安定した操作性を得ることができる。さらに、前記押圧操作部は、一対であるため、使用者の指等で摘んで押圧し易く、操作性をより一層向上することができる。   In the fixture having this configuration, since the pressing operation portion is provided in the locking portion and not in the contact portion, the contact portion is elastically deformed according to the thickness of the attached member. However, this elastic deformation does not affect the pressing operation portion. Therefore, when removing the fixture according to the present invention from the attached member, it is sufficient to always press the pressing operation portion with a constant operating force, and stable operability can be obtained. Furthermore, since the said press operation part is a pair, it is easy to pick and press with a user's finger | toe etc., and operativity can be improved further.

また、本発明にかかる固定具は、前記係止部が、前記保持部の一端部から突設された支柱部と、前記支柱部の先端に弾性を有する屈曲可能な接続部を介して接続されると共に、互いに略180度位相した位置に設けられ、前記保持部に向けて当該支柱部から離れる方向に延出する折り返し部と、を備え、前記一対の押圧操作部は、前記折り返し部の自由端に各々設けられた構成とすることもできる。   Further, in the fixing device according to the present invention, the locking portion is connected via a support column projecting from one end of the holding unit and a flexible connecting portion having elasticity at the tip of the support column. And a folded portion that extends in a direction away from the support column toward the holding portion, and the pair of pressing operation portions are free of the folded portion. It can also be set as the structure each provided in the edge.

そしてまた、前記一対の押圧操作部は、前記係止部を前記取付孔に挿入した際に、当該被取付部材の他方から見て、略コ字状を有し、互いに反対の向きで前記係止部に設けられていてもよい。この構成の場合、前記一対の当接片は、前記一対の押圧操作部の略コ字状によって画定される内側空間に対応した位置に、各々配設することもでき
る。
Further, the pair of pressing operation portions have a substantially U-shape when viewed from the other side of the attached member when the locking portion is inserted into the attachment hole, and the engagement portions are opposed to each other. It may be provided at the stop. In this configuration, the front Symbol pair of contact pieces, at positions corresponding to the inner space defined by a substantially U-shaped pair of pushing operation section can also be respectively disposed.

また、本発明にかかる固定具では、前記一対の押圧操作部の先端部は、前記係止部を前記取付孔に挿入した際に、前記被取付部材の他方の面に各々当接するよう構成することもできる。このように構成することにより、当接部及び押圧操作部と、係止部とによって被取付部材を挟持することができる。このため、さらに被取付部材に確実に固定することができる。 In the fixing device according to the present invention, the distal end portions of the pair of pressing operation portions are configured to abut against the other surface of the attached member when the locking portion is inserted into the attachment hole. You can also By comprising in this way, a to-be-attached member can be clamped by a contact part, a press operation part, and a latching | locking part. For this reason, it can fix to a to-be-attached member reliably.

さらにまた、本発明にかかる固定具では、前記一対の押圧操作部の各々の先端は、前記係止部を前記取付孔に挿入した際に、前記一対の当接片の各々の先端よりも前記保持部側に位置すると共に、前記被取付部材の他方の面から見て、前記一対の当接片と重なった部分を備えるよう構成することもできる。 Further, in the fastener according to the present invention, each of the tip of the previous SL pair of pressing operation portion, the locking portion when inserted into the mounting hole, from the front end of each of said pair of contact piece It can be configured to include a portion that is located on the holding portion side and overlaps with the pair of contact pieces when viewed from the other surface of the attached member.

前記固定具をこのように構成することで、固定具を被取付部材から取外すため、前記一対の押圧操作部によって、前記係止部を両側から押圧して、当該係止部を縮小変形させる際に、前記押圧操作部が、前記保持部が形成されている側とは反対方向(被取付部材方向)に変形しようとしても、当該押圧操作部の前記当接片と重なった部分が、当該当接片に当接することになる。したがって、前記押圧操作部が前記方向に変形することを防止することができる。このため、前記係止部が不用意に広がることを防止することができ、当該係止部を、さらに簡単に前記取付孔から抜脱することができる。   By configuring the fixing device in this way, the fixing device is removed from the attached member, and therefore, when the locking portion is pressed from both sides by the pair of pressing operation portions, the locking portion is reduced and deformed. In addition, even if the pressing operation part is deformed in the direction opposite to the side where the holding part is formed (the direction of the attached member), the portion of the pressing operation part that overlaps the contact piece is It will contact the contact piece. Therefore, it is possible to prevent the pressing operation portion from being deformed in the direction. For this reason, it can prevent that the said latching part spreads carelessly, and the said latching | locking part can be extracted from the said attachment hole still more easily.

また、前記一対の押圧操作部は、前記対象物の保持部への挿入方向に対し略垂直な方向に延出されていてもよい。このように構成することで、前記利点に加え、前記押圧操作部を操作する際に、前記保持部に保持された対象物が邪魔になることを防止することができる。   Further, the pair of pressing operation units may extend in a direction substantially perpendicular to a direction in which the object is inserted into the holding unit. By comprising in this way, in addition to the said advantage, when operating the said press operation part, it can prevent that the target object hold | maintained at the said holding | maintenance part becomes obstructive.

そしてまた、前記一対の押圧操作部の各々の先端は、前記係止部を前記取付孔に挿入した際に、前記保持部の外壁に対し略面一となる位置まで延出していてもよい。このように構成することで、前述した利点に加え、押圧操作部を操作する際に、保持部が邪魔になることを防止することができる。また、固定具の小型化を達成することもできる。   Further, the distal ends of the pair of pressing operation portions may extend to a position that is substantially flush with the outer wall of the holding portion when the locking portion is inserted into the mounting hole. By comprising in this way, in addition to the advantage mentioned above, when operating a press operation part, it can prevent that a holding | maintenance part becomes obstructive. In addition, the size of the fixture can be reduced.

さらにまた、前記一対の押圧操作部の先端は、前記係止部を前記取付孔に挿入した際に、前記保持部の外壁を超える位置まで各々延出していてもよい。   Furthermore, the distal ends of the pair of pressing operation portions may extend to positions exceeding the outer wall of the holding portion when the locking portion is inserted into the mounting hole.

また、前記一対の押圧操作部の先端には、前記保持部側に向けて突出した突出部を形成することもできる。このように構成することで、押圧操作部を操作する際に、突出部に使用者の指等を当てることができ、さらに操作性を向上することができる。   Moreover, the protrusion part which protruded toward the said holding | maintenance part side can also be formed in the front-end | tip of a pair of said press operation part. By comprising in this way, when operating a press operation part, a user's finger | toe etc. can be applied to a protrusion part, and operativity can be improved further.

そしてまた、本発明にかかる固定具では、前記折り返し部の自由端側に、前記支柱部側よりも肉薄な第1の肉薄部を形成してもよい。このように構成することで、前記係止部を前記取付孔に挿入した際に、前記折り返し部の第1の肉薄部との段差部分を、前記被取付部材の他方の面に当接させることができる。したがって、前記利点に加え、前記被取付部材に固定具をより一層安定した状態で固定することができる。   In the fixture according to the present invention, a first thin portion thinner than the support portion may be formed on the free end side of the folded portion. With this configuration, when the locking portion is inserted into the mounting hole, the stepped portion of the folded portion with the first thin portion is brought into contact with the other surface of the mounted member. Can do. Therefore, in addition to the advantages, the fixture can be fixed to the attached member in a more stable state.

また、本発明にかかる固定具では、前記一対の押圧操作部は、前記折り返し部の自由端側に、前記第1の肉薄部よりも肉薄な第2の肉薄部を各々形成した構成とすることができる。この第2の肉薄部は肉薄であるため変形しやすく、前記一対の押圧操作部によって、前記係止部を両側から押圧する際に、例えば、押圧操作部の剛性等によって、当該押圧操作部が、前記折り返し部との接続部分(折り返し部の自由端先端)を支点として、回転しようとする力が生じたとしても、第2の肉薄部の変形によってこの力が吸収され、前記回転が生じることを防止することができる。したがって、前記被取付部材から固定具を取外す際に、前記押圧操作部の長さに関わらず、一対の押圧操作部の操作によって、前記係止部をより一層縮小変形させやすくすることができる。   In the fixing device according to the present invention, the pair of pressing operation portions are configured such that a second thin portion thinner than the first thin portion is formed on the free end side of the folded portion. Can do. Since the second thin portion is thin, it is easily deformed, and when the locking portion is pressed from both sides by the pair of pressing operation portions, for example, due to the rigidity of the pressing operation portion, the pressing operation portion is Even if a force to rotate is generated with the connecting portion with the folded portion (the free end tip of the folded portion) as a fulcrum, the force is absorbed by the deformation of the second thin portion, and the rotation occurs. Can be prevented. Therefore, when removing the fixture from the attached member, the engaging portion can be further reduced and deformed more easily by the operation of the pair of pressing operation portions regardless of the length of the pressing operation portion.

さらにまた、本発明にかかる固定具の係止部は、前記被取付部材の取付孔に形成された平坦な面に当接可能な平坦な面を有し、当該係止部が前記取付孔に挿入された際に、当該係止部に形成された平坦な面が当該取付孔に形成された平坦な面に当接して回り止めされる構成を備えることができる。このように構成することで、例えば、固定具を被取付部材に取り付ける際や、取り付けた後に、当該固定具が被取付部材に対し回転することを防止することができる。したがって、固定具が被取付部材に対し、常に所望の方向を向くように配設することができる。   Furthermore, the locking portion of the fixing device according to the present invention has a flat surface that can come into contact with a flat surface formed in the mounting hole of the mounted member, and the locking portion is in the mounting hole. When inserted, the flat surface formed in the said latching | locking part can be equipped with the structure which contact | abuts to the flat surface formed in the said attachment hole, and is prevented from rotating. By comprising in this way, when attaching a fixing tool to a to-be-attached member, or after attaching, for example, it can prevent that the said fixing tool rotates with respect to a to-be-attached member. Therefore, it can arrange | position so that a fixing device may always face a desired direction with respect to a to-be-attached member.

本発明にかかる固定具は、係止部に押圧操作部が設けられているため、被取付部材の厚さに応じて当接部が変形したとしても、この変形が前記押圧操作部に影響を与えることがない。したがって、押圧操作部を一定の操作力で押圧するだけで、固定具を被取付部材から取外すことができ、取外し操作の安定性を向上することができる。また、前記押圧操作部は、一対であるため、使用者の指等で摘んで押圧し易く、操作性をより一層向上することができる。   In the fixing device according to the present invention, since the pressing operation portion is provided in the locking portion, even if the contact portion is deformed according to the thickness of the attached member, the deformation affects the pressing operation portion. Never give. Therefore, the fixing tool can be removed from the attached member simply by pressing the pressing operation portion with a constant operating force, and the stability of the removing operation can be improved. Moreover, since the said press operation part is a pair, it is easy to pick and press with a user's finger | toe etc., and operability can be improved further.

次に、本発明の好適な実施の形態にかかる固定具について図面を参照して説明する。なお、以下に記載される実施の形態は、本発明を説明するための例示であり、本発明をこれらの実施の形態にのみ限定するものではない。したがって、本発明は、その要旨を逸脱しない限り、様々な形態で実施することができる。   Next, a fixture according to a preferred embodiment of the present invention will be described with reference to the drawings.

なお、実施の形態1では、固定具の保持部に保持される対象物として、例えば、電線や配管等のような線材を用い、固定具が取付けられる被取付部材としてシャーシを用いた場合について説明するが、これらに限定されるものではない。また、便宜上、実施の形態1では、シャーシに対し固定具を取付けた際に、保持部が位置する方向を「上」とし、係止部が位置する方向を「下」として説明する。   In the first embodiment, the case where, for example, a wire such as an electric wire or a pipe is used as an object to be held by the holding portion of the fixture, and a chassis is used as a member to be attached to which the fixture is attached. However, it is not limited to these. For convenience, in the first embodiment, when the fixture is attached to the chassis, the direction in which the holding portion is located is “upper”, and the direction in which the locking portion is located is “lower”.

図1〜図15に示すように、実施の形態1にかかる固定具1は、線材S(図15参照)を保持する保持部10と、保持部10に設けられ且つシャーシ100の取付孔101に挿入されてシャーシ100の一方の面(以下、この面を「下面100B」とする)に係止される係止部20と、保持部10に設けられ且つシャーシ100他方の面(以下、この面を「上面100A」とする)に当接する当接部30と、係止部20に設けられ、係止部20を両側から押圧して縮小変形を行なわせ、係止部20を取付孔101から取外し可能な状態にする一対の押圧操作部40A及び40Bと、を備えて構成されている。   As shown in FIGS. 1 to 15, the fixture 1 according to the first embodiment includes a holding unit 10 that holds the wire S (see FIG. 15), and a mounting portion 101 provided in the holding unit 10 and in the mounting hole 101 of the chassis 100. A locking portion 20 that is inserted and locked to one surface of the chassis 100 (hereinafter referred to as “lower surface 100B”), and the other surface of the chassis 100 (hereinafter referred to as this surface) provided in the holding portion 10. Is provided on the locking portion 20, and the locking portion 20 is pressed from both sides to cause reduction deformation, and the locking portion 20 is removed from the mounting hole 101. And a pair of pressing operation units 40A and 40B that can be removed.

保持部10は、ベース11と、ベース11の一端(図2でいう右側端)に連続して上方に延出形成された第1の保持部12Aと、ベース11の他端(図2でいう左側端)に連続して上方に延出形成された第2の保持部12Bを備えている。第1の保持部12Aは、その長手方向中程に、第1の保持部12Aを略90度内側に折り曲げることができるように切欠き13が設けられている。また、第1の保持部12Aの自由端には、鉤形係合部14が設けられている。一方、第2の保持部12Bは、第1の保持部12Aの高さ(長さ)の略半分の高さ(長さ)を有しており、その自由端には、鉤形係合部14が係合する被係合部15が形成されている。この被係合部15は、鉤形係合部14を貫通挿入する挿入孔15Aと、挿入孔15Aに貫通挿入された鉤形係合部14と係合する係合片15Bとから構成されている。   The holding unit 10 includes a base 11, a first holding unit 12 </ b> A that extends upward continuously from one end of the base 11 (the right end in FIG. 2), and the other end of the base 11 (in FIG. 2). The second holding portion 12B is formed to continuously extend to the left end). The first holding portion 12A is provided with a notch 13 in the middle of the longitudinal direction so that the first holding portion 12A can be bent inward by approximately 90 degrees. A hook-shaped engagement portion 14 is provided at the free end of the first holding portion 12A. On the other hand, the second holding portion 12B has a height (length) that is substantially half the height (length) of the first holding portion 12A, and has a hook-shaped engagement portion at its free end. An engaged portion 15 with which 14 is engaged is formed. The engaged portion 15 includes an insertion hole 15A for penetrating and inserting the hook-shaped engaging portion 14, and an engagement piece 15B for engaging with the hook-shaped engaging portion 14 inserted through the insertion hole 15A. Yes.

この保持部10は、第1の保持部12Aを切欠き13を支点として内側に折り曲げ、鉤形係合部14を挿入孔15Aに挿入して係合片15Bに係合させることで、図1に示すような略四角形の空間を画定する。そして、この空間には、図15に示すように、線材Sが挿入され、保持される。   The holding portion 10 is formed by bending the first holding portion 12A inwardly with the notch 13 as a fulcrum and inserting the hook-shaped engaging portion 14 into the insertion hole 15A to engage with the engaging piece 15B. A substantially rectangular space as shown in FIG. And as shown in FIG. 15, the wire S is inserted and hold | maintained in this space.

係止部20は、保持部10のベース11の下面略中央部から下方に向けて突設された支柱部21と、支柱部21の先端に弾性を有する屈曲可能な薄肉の接続部22A及び22Bを介して各々接続される折り返し部23A及び23Bと、を備えて構成されている。   The locking part 20 includes a support part 21 projecting downward from a substantially central part of the lower surface of the base 11 of the holding part 10, and bendable thin connecting parts 22 </ b> A and 22 </ b> B having elasticity at the end of the support part 21. Folding portions 23A and 23B that are connected to each other via a cable.

折り返し部23A及び23Bは、支柱部21に対し、互いに略180度位相した位置に設けられており、斜め上方に向けて支柱部21から離れる方向に延出されている。この折り返し部23A及び23Bの先端側(自由端側)には、支柱部21側よりも肉薄な第1の肉薄部24A及び24Bが形成されている。そして、係止部20の上部は、シャーシ100に形成された取付孔101の径よりも大きくなるように広がった状態となっている。なお、第1の肉薄部24A及び24Bは、折り返し部23A及び23Bの支柱部21側よりも肉薄に形成されているため、折り返し部23A及び23Bに段差部分25A及び25Bを各々形成することになる。   The folded portions 23A and 23B are provided at positions that are substantially 180 degrees from each other with respect to the support column 21, and extend in a direction away from the support column 21 obliquely upward. First thin portions 24A and 24B that are thinner than the column portion 21 side are formed on the distal end sides (free end sides) of the folded portions 23A and 23B. And the upper part of the latching | locking part 20 is the state expanded so that it might become larger than the diameter of the attachment hole 101 formed in the chassis 100. FIG. The first thin portions 24A and 24B are formed thinner than the turn-back portions 23A and 23B than the support portion 21 side, so that step portions 25A and 25B are formed in the turn-back portions 23A and 23B, respectively. .

当接部30は弾性を有し、保持部10のベース11の下面の両側(図2でいう右側及び左側)から互いの下端が離れるよう斜め下方に向けて互いに略180度位相して延出形成された2つの当接片30A及び30Bを備えている。この当接片30A及び30Bは、特に図7に示すように、中心線Oに対し互いにオフセットされた位置に配設されている。また、当接片30A及び30Bの下端部は、後に詳述する押圧操作部40A及び40Bの凹部空間43A及び43Bに対向する位置にあり、固定具1がシャーシ100に固定され、当接片30A及び30Bがシャーシ100の上面100Aに当接して押圧する際に、押圧操作部40A及び40Bと干渉し合うことがないようになっている。   The contact portion 30 has elasticity, and extends at an angle of approximately 180 degrees toward each other downward from both sides (the right side and the left side in FIG. 2) of the lower surface of the base 11 of the holding portion 10 toward the lower side. Two contact pieces 30A and 30B are provided. The contact pieces 30A and 30B are disposed at positions offset from each other with respect to the center line O as shown in FIG. Further, the lower end portions of the contact pieces 30A and 30B are located at positions facing the recessed spaces 43A and 43B of the pressing operation portions 40A and 40B, which will be described in detail later, and the fixture 1 is fixed to the chassis 100, and the contact pieces 30A. And 30B do not interfere with the pressing operation portions 40A and 40B when they are pressed against the upper surface 100A of the chassis 100.

押圧操作部40A及び40Bは、折り返し部23A及び23Bの上端部より略直角方向に屈曲して外方に延出した略コ字状(図7参照)の板状部41A及び41Bを有し、板状部41A及び41Bの先端には、上方に向けて突出した突出部42A及び42Bが形成されている。この押圧操作部40A及び40Bは、図7に示すように、底面から見て互いに反対の向きとなるように配設されている。なお、板状部41A及び41Bは、保持部10を閉じた際(図1参照)に開口している面に対し、略垂直な方向に延出している。すなわち、保持部10に保持された線材S(図15参照)の挿入方向に対し、略垂直な方向に延出している。このため、押圧操作部40A及び40Bを操作する際に、保持部10に保持された線材Sに、例えば使用者の指等が当たることを防止できる。したがって、線材Sが邪魔になることがなく、操作性が向上する。   The pressing operation portions 40A and 40B have substantially U-shaped (see FIG. 7) plate-like portions 41A and 41B that are bent in a substantially right angle direction from the upper end portions of the folded portions 23A and 23B and extend outward. Protruding portions 42A and 42B projecting upward are formed at the tips of the plate-like portions 41A and 41B. As shown in FIG. 7, the pressing operation portions 40A and 40B are arranged so as to be opposite to each other when viewed from the bottom surface. The plate-like portions 41A and 41B extend in a direction substantially perpendicular to the surface opened when the holding portion 10 is closed (see FIG. 1). That is, it extends in a direction substantially perpendicular to the insertion direction of the wire S (see FIG. 15) held by the holding unit 10. For this reason, when operating the pressing operation parts 40A and 40B, it can prevent that a user's finger | toe etc. contact | win the wire S hold | maintained at the holding | maintenance part 10, for example. Therefore, the wire S does not get in the way and the operability is improved.

この押圧操作部40A及び40Bは、固定具1をシャーシ100に固定した際に、シャーシ100の上面100A上に配置され、シャーシ100の上面100Aに当接して上面100Aを押圧可能となっている。そして、押圧操作部40A及び40Bは、使用者が指等で突出部42A及び42Bを摘んで支柱部21に向けて押圧することで、接続部22A及び22Bが内側に屈曲して、係止部20の折り返し部23A及び23Bを互いに近づく方向に移動させる。この結果、係止部20は縮小変形することになる。   The pressing operation units 40A and 40B are arranged on the upper surface 100A of the chassis 100 when the fixture 1 is fixed to the chassis 100, and can contact the upper surface 100A of the chassis 100 to press the upper surface 100A. Then, the pressing operation portions 40A and 40B are formed in such a manner that the connecting portions 22A and 22B are bent inward by the user holding the protruding portions 42A and 42B with a finger or the like and pressing the protruding portions 42A and 42B. The 20 folded portions 23A and 23B are moved in a direction approaching each other. As a result, the locking portion 20 is reduced and deformed.

次に、実施の形態1にかかる固定具1の具体的動作について説明する。   Next, a specific operation of the fixture 1 according to the first embodiment will be described.

先ず、固定具1をシャーシ100に取付ける際は、図13に示すように、固定具1の係止部20側をシャーシ100に対向させ、係止部20を取付孔101内に挿入させる。この取付孔101への挿入動作時、係止部20は、折り返し部23A及び23Bが、取付孔101を画定している壁面に当接し、この壁面によって、支柱部21に向けて(すなわち、取付孔101の略中心方向に向けて)押圧される。この押圧により、接続部22A及び22Bが内側に屈曲され、結果として折り返し部23A及び23Bが縮小変形して取付孔101を貫通可能となる。   First, when attaching the fixture 1 to the chassis 100, as shown in FIG. 13, the locking portion 20 side of the fixture 1 is opposed to the chassis 100, and the locking portion 20 is inserted into the mounting hole 101. At the time of the insertion operation into the mounting hole 101, the locking portion 20 has the folded portions 23A and 23B abutted against the wall surface defining the mounting hole 101, and is directed toward the support column 21 by this wall surface (that is, the mounting portion 20). It is pressed toward the substantially central direction of the hole 101). By this pressing, the connecting portions 22A and 22B are bent inward, and as a result, the folded portions 23A and 23B are reduced and deformed and can pass through the mounting hole 101.

次に、取付孔101を貫通した係止部20は、接続部がその弾性復元力により元の状態に戻り、折り返し部23A及び23Bが元の位置に戻る。この動作により、折り返し部23A及び23Bの上部は、取付孔101よりも外側に拡大し、段差部分25A及び25Bを、シャーシ100の下面100Bに当接させる。したがって、シャーシ100に固定具1をより一層安定した状態で固定することができる。   Next, as for the latching | locking part 20 which penetrated the attachment hole 101, a connection part returns to an original state with the elastic restoring force, and folding | returning parts 23A and 23B return to an original position. By this operation, the upper portions of the folded portions 23 </ b> A and 23 </ b> B expand outside the mounting hole 101, and the step portions 25 </ b> A and 25 </ b> B are brought into contact with the lower surface 100 </ b> B of the chassis 100. Therefore, the fixture 1 can be fixed to the chassis 100 in a more stable state.

また、係止部20が、取付孔101を貫通すると、当接片30A及び30Bがシャーシ100の上面100Aに当接して、その弾性力により上面100Aを押圧する。さらにまた、押圧操作部40A及び40Bが、シャーシ100の上面100Aに位置し、その弾性力により上面100Aを押圧する。この時、当接片30A及び30Bは、押圧操作部40A及び40Bの略コ字状によって画定される内部空間内に納まるため、当接片30A及び30Bと、押圧操作部40A及び40Bとが干渉し合うことがない。   Moreover, when the latching | locking part 20 penetrates the attachment hole 101, contact piece 30A and 30B will contact | abut to the upper surface 100A of the chassis 100, and will press the upper surface 100A with the elastic force. Furthermore, the pressing operation units 40A and 40B are located on the upper surface 100A of the chassis 100, and press the upper surface 100A by its elastic force. At this time, since the contact pieces 30A and 30B are accommodated in the internal space defined by the substantially U-shape of the pressing operation portions 40A and 40B, the contact pieces 30A and 30B and the pressing operation portions 40A and 40B interfere with each other. I don't get along.

このようにして、図1に示すように、係止部20の段差部分25A及び25Bによってシャーシ100の下面100Bを押圧し、当接片30A及び30Bと、押圧操作部40A及び40Bとによって、シャーシ100の上面100Aを押圧することで、シャーシ100を確実に挟持する。この状態の時、押圧操作部40A及び40Bの先端、すなわち突出部42A及び42Bの位置は、保持部10の外側表面と略面一となっている。このため、押圧操作部40A及び40Bが邪魔になることがなく、固定具1の小型化を達成することもできる。   In this manner, as shown in FIG. 1, the lower surface 100B of the chassis 100 is pressed by the step portions 25A and 25B of the locking portion 20, and the chassis is formed by the contact pieces 30A and 30B and the pressing operation portions 40A and 40B. By pressing the upper surface 100A of the 100, the chassis 100 is securely clamped. In this state, the tips of the pressing operation portions 40A and 40B, that is, the positions of the protruding portions 42A and 42B are substantially flush with the outer surface of the holding portion 10. For this reason, pressing operation part 40A and 40B do not become obstructive, and size reduction of fixture 1 can also be achieved.

次に、シャーシ100に固定された固定具1に線材Sを保持させる際は、ベース11と、第1の保持部12Aと、第2の保持部12Bとで画定される空間に、所定量(所定本数)の線材Sを入れた後、切欠き13を支点として、第1の保持部12Aを略90度内側に折り曲げ、鉤形係合部14を挿入孔15Aに挿入して係合片15Bに係合させればよい。(図15参照)。   Next, when the wire S is held by the fixture 1 fixed to the chassis 100, a predetermined amount (in a space defined by the base 11, the first holding portion 12A, and the second holding portion 12B ( After the predetermined number of wires S have been inserted, the first holding portion 12A is bent approximately 90 degrees inward with the notch 13 as a fulcrum, and the hook-shaped engagement portion 14 is inserted into the insertion hole 15A to engage the engagement piece 15B. Can be engaged. (See FIG. 15).

一方、シャーシ100に固定された固定具1から線材Sを取外す際は、鉤形係合部14を押圧して縮小変形させ、係合片15Bとの係合を解除すればよい。   On the other hand, when removing the wire S from the fixture 1 fixed to the chassis 100, the hook-shaped engagement portion 14 may be pressed and deformed to be released, and the engagement with the engagement piece 15B may be released.

また、固定具1をシャーシ100から取外す際は、使用者が指等で、押圧操作部40A及び40Bの突出部42A及び42Bを摘んで突出部42A及び42Bが互いに近づく方向に押圧すると、接続部22A及び22Bが内側に屈曲され、結果として折り返し部23A及び23Bが縮小変形し、係止部20を取付孔101から簡単に抜脱することができる。この時、押圧操作部40A及び40Bは、保持部10に保持された線材S(図15参照)の挿入方向に対し、略垂直な方向に延出しているため、押圧操作部40A及び40Bを操作する際に、保持部10に保持された線材Sが邪魔になることがない。したがって、押圧操作部40A及び40Bを容易に押圧することができる。   Further, when the fixing tool 1 is removed from the chassis 100, when the user grips the protruding portions 42A and 42B of the pressing operation portions 40A and 40B with a finger or the like and presses the protruding portions 42A and 42B toward each other, the connecting portion 22A and 22B are bent inward, and as a result, the folded portions 23A and 23B are reduced and deformed, and the locking portion 20 can be easily removed from the mounting hole 101. At this time, since the pressing operation units 40A and 40B extend in a direction substantially perpendicular to the insertion direction of the wire S held by the holding unit 10 (see FIG. 15), the pressing operation units 40A and 40B are operated. In doing so, the wire S held by the holding unit 10 does not get in the way. Therefore, the pressing operation units 40A and 40B can be easily pressed.

また、押圧操作部40A及び40Bを押圧しても、当接片30A及び30Bは、押圧操作部40A及び40Bの略コ字状によって画定される内部空間内に納まった状態にあり、当接片30A及び30Bと、押圧操作部40A及び40Bとが干渉し合うことはない。さらにまた、押圧操作部40A及び40Bは、係止部20設けられており、当接部30に設けられている訳ではないため、シャーシ100の厚さに応じて当接片30A及び30Bが変形していたとしても、この変形が押圧操作部40A及び40Bに影響を与えることがない。このため、押圧操作部40A及び40Bは、常に一定の操作力を付与すれば、係止部20を縮小変形させることができる。   Further, even when the pressing operation portions 40A and 40B are pressed, the contact pieces 30A and 30B are in a state of being accommodated in the internal space defined by the substantially U-shape of the press operation portions 40A and 40B. 30A and 30B and press operation part 40A and 40B do not interfere with each other. Furthermore, since the pressing operation portions 40A and 40B are provided in the locking portion 20 and not in the contact portion 30, the contact pieces 30A and 30B are deformed according to the thickness of the chassis 100. Even if it does, this deformation | transformation does not affect the press operation parts 40A and 40B. For this reason, if the pressing operation parts 40A and 40B always apply a constant operating force, the locking part 20 can be reduced and deformed.

なお、実施の形態1では、保持部10として、閉じた際に略四角形となる形状のものについて説明したが、これに限らず、保持部10は、保持したい対象物に応じて、例えば、略C字状(閉じた時は略O字状)、上部が開口された略C字状の弾性体からなり、断面略円形のケーブルを保持するもの、弾性を有するベルト状部材からなり、対象物に巻き付けることで保持するもの、電気機器等の脚を挿入する挿入部を有したもの等、様々な形状を採用することができる。   In the first embodiment, the holding unit 10 has been described as having a substantially square shape when closed. However, the holding unit 10 is not limited to this, and the holding unit 10 may have, for example, a substantially rectangular shape depending on an object to be held. C-shaped (substantially O-shaped when closed), consisting of a substantially C-shaped elastic body with an opening at the top, holding a cable with a substantially circular cross section, consisting of a belt-like member having elasticity, Various shapes can be employed, such as those that are held by being wound around and those that have an insertion portion for inserting a leg of an electrical device or the like.

また、対象物は、線材Sに限定されるものではなく、保持部10の形状を対応させることで、種々な対象物に応用することができる。また、被取付部材は、シャーシ100に限定されるものではなく、例えば、パネルや、ハウジング、建物の壁面、天井等、種々の被取付部材に応用することができる。   Moreover, a target object is not limited to the wire S, By applying the shape of the holding | maintenance part 10, it can apply to a various target object. Further, the attached member is not limited to the chassis 100, and can be applied to various attached members such as a panel, a housing, a wall surface of a building, a ceiling, and the like.

FIG. 21 is a bottom view of the fixture shown in FIG. 16, and FIG. 22 is a sectional view taken along line XXII-XXII shown in FIG.

なお、実施の形態2では、実施の形態1で説明した部材と同様の部材には、同一の符号を付し、その詳細な説明は省略する。   In the second embodiment, the same members as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図16〜図22に示すように、実施の形態2にかかる固定具2の、実施の形態1にかかる固定具1と異なる主な点は、当接部130の形状と、押圧操作部140A及び140Bの形状と、押圧操作部140A及び140Bの折り返し部23A及び23Bの先端側(自由端側)に、第2の肉薄部34A及び34Bを形成した点である。   As shown in FIGS. 16 to 22, the main points of the fixture 2 according to the second embodiment different from the fixture 1 according to the first embodiment are the shape of the contact portion 130, the pressing operation portion 140 </ b> A, and the like. The second thin portions 34A and 34B are formed on the shape of 140B and the distal end side (free end side) of the folded portions 23A and 23B of the pressing operation portions 140A and 140B.

すなわち、固定具2の当接部130は弾性を有し、保持部10のベース11の下面の両側(図17でいう右側及び左側)から互いの下端が離れるよう斜め下方に向けて互いに略180度位相して延出形成された2つの当接片130A及び130Bを備えている。この当接片130A及び130Bは、対角線上に張り出した状態で保持部10の外壁よりも外側に延出している。また、当接片130A及び130Bの各々の先端は、特に、図16、図19、図20及び図22に示すように、固定具2をシャーシ100に取付けた際に、シャーシ100の上面100Aに当接すると共に、後に詳述する押圧操作部140A及び140Bの先端よりも下に位置するよう構成されている。また、当接片130A及び130Bの各々の先端は、平面視(図20参照)で、押圧操作部140A及び140Bと上下に重なるよう形成されている。   That is, the abutting portion 130 of the fixture 2 has elasticity, and is substantially 180 toward the lower side so that the lower ends are separated from both sides (the right side and the left side in FIG. 17) of the lower surface of the base 11 of the holding unit 10. Two contact pieces 130A and 130B that are extended in phase with each other are provided. The contact pieces 130 </ b> A and 130 </ b> B extend outward from the outer wall of the holding unit 10 in a state of extending diagonally. Further, the tips of the contact pieces 130A and 130B are particularly formed on the upper surface 100A of the chassis 100 when the fixture 2 is attached to the chassis 100, as shown in FIGS. 16, 19, 20, and 22. While abutting, it is comprised so that it may be located below the front-end | tip of the press operation parts 140A and 140B explained in full detail later. Further, the tips of the contact pieces 130A and 130B are formed so as to overlap vertically with the pressing operation portions 140A and 140B in a plan view (see FIG. 20).

押圧操作部140A及び140Bは、折り返し部23A及び23Bの上端部より略直角方向に屈曲して外方に延出した略コ字状(図21参照)の板状部141A及び141Bを有し、板状部141A及び141Bの先端には、上方に向けて突出した突出部142A及び142Bが形成されている。この押圧操作部140A及び140Bは、図21に示すように、底面から見て互いに反対の向きとなるように配設されている。なお、板状部141A及び141Bは、実施の形態1と同様に、保持部10を閉じた際(図16、図19及び図22参照)に開口している面に対し、略垂直な方向に延出しており、保持部10に保持される線材S(図15参照)の挿入方向に対し、略垂直な方向に延出している。   The pressing operation parts 140A and 140B have substantially U-shaped plate-like parts 141A and 141B that are bent in a substantially right angle direction from the upper ends of the folded parts 23A and 23B and extend outward (see FIG. 21). Projecting portions 142A and 142B projecting upward are formed at the tips of the plate-like portions 141A and 141B. As shown in FIG. 21, the pressing operation portions 140A and 140B are disposed so as to be opposite to each other when viewed from the bottom surface. The plate-like portions 141A and 141B are arranged in a direction substantially perpendicular to the surface opened when the holding portion 10 is closed (see FIGS. 16, 19, and 22), as in the first embodiment. It extends in a direction substantially perpendicular to the insertion direction of the wire S (see FIG. 15) held by the holding unit 10.

この押圧操作部140A及び140Bは、特に、図16、図19及び図22に示すように、固定具2をシャーシ100に固定した際に、シャーシ100の上面100Aと隙間をおいて配置され、使用者が指等で突出部142A及び142Bを摘んで支柱部21に向けて押圧することで、接続部22A及び22Bが内側に屈曲して、係止部20の折り返し部23A及び23Bを互いに近づく方向に移動させる。この結果、係止部20は縮小変形することになる。   The pressing operation parts 140A and 140B are arranged with a gap from the upper surface 100A of the chassis 100 when the fixing tool 2 is fixed to the chassis 100, as shown in FIGS. When a person grips the protrusions 142A and 142B with a finger or the like and presses them toward the support column 21, the connecting portions 22A and 22B are bent inward, and the folded portions 23A and 23B of the locking portion 20 are brought closer to each other. Move to. As a result, the locking portion 20 is reduced and deformed.

また、板状部141A及び141Bの折り返し部23A及び23B側には、第1の肉薄部24A及び24Bよりも肉に形成された第2の肉薄部34A及び34Bが、各々形成されている。この第2の肉薄部34A及び34Bは、肉薄に構成されているため変形しやすく、押圧操作部140A及び140Bによって、係止部20の折り返し部23A及び23Bを両側から押圧する際に、例えば、押圧操作部140A及び140Bが、その剛性等によって折り返し部23A及び23Bとの接続部分を支点として、回転しようとする力を吸収することができる。したがって、シャーシ100から固定具2を取外す際に、一対の押圧操作部140A及び140Bの操作によって、係止部20をより一層縮小変形させやすくすることができる。 Further, the folded portions 23A and 23B side of the plate-like portion 141A and 141B, the second thin portion 34A and 34B formed in the meat thin than the first thin portion 24A and 24B, are respectively formed. Since the second thin portions 34A and 34B are configured to be thin, they are easily deformed.When the folding portions 23A and 23B of the locking portion 20 are pressed from both sides by the pressing operation portions 140A and 140B, for example, The pressing operation portions 140A and 140B can absorb the force to rotate by using the connection portions with the folded portions 23A and 23B as fulcrums due to their rigidity and the like. Therefore, when removing the fixture 2 from the chassis 100, the engaging portion 20 can be further reduced and deformed more easily by operating the pair of pressing operation portions 140A and 140B.

さらにまた、押圧操作部140A及び140Bは、特に、図16、図19及び図22に示すように、固定具2をシャーシ100に固定した際に、各々の先端が、当接片130A及び130Bの各々の先端よりも上側に位置すると共に、平面視で、当接片130A及び130Bの先端に対し上下に重なるよう形成されている。このように構成することで、固定具2をシャーシ100から取外すため、一対の押圧操作部140A及び140Bを両側から押圧する際に、押圧操作部140A及び140Bが、下方に変形しようとしても、押圧操作部140A及び140Bの当接片130A及び130Bと重なった部分が、当接片130A及び130Bに当接することになる。したがって、押圧操作部140A及び140Bが下方に変形することを防止することができる。   Furthermore, as shown in FIGS. 16, 19, and 22, the pressing operation portions 140A and 140B are arranged so that the tips of the pressing operation portions 140A and 140B are the contact pieces 130A and 130B, respectively, when the fixture 2 is fixed to the chassis 100. It is located above each tip and is formed so as to overlap vertically with the tips of the contact pieces 130A and 130B in plan view. With this configuration, when the pair of pressing operation parts 140A and 140B are pressed from both sides in order to remove the fixture 2 from the chassis 100, the pressing operation parts 140A and 140B are pressed even if they are deformed downward. The portions overlapping the contact pieces 130A and 130B of the operation units 140A and 140B come into contact with the contact pieces 130A and 130B. Therefore, it is possible to prevent the pressing operation portions 140A and 140B from being deformed downward.

次に、実施の形態2にかかる固定具2の具体的動作について説明する。   Next, a specific operation of the fixture 2 according to the second embodiment will be described.

先ず、固定具2をシャーシ100に取付ける際は、実施の形態1と同様に、固定具2の係止部20を取付孔101内に挿入させ、段差部分25A及び25Bを、シャーシ100の下面100Bに当接させる。また、係止部20が、取付孔101を貫通すると、当接片130A及び130Bがシャーシ100の上面100Aに当接して、その弾性力により上面100Aを押圧する。この時、押圧操作部140A及び140Bは、シャーシ100の上面100Aを押圧することなく、上面100Aと隙間をおいて上面100Aの上方に位置する(図16、図19及び図22参照)が、シャーシ100は、段差部分25A及び25Bと、当接片130A及び130Bとによって挟持された状態となり、固定具2は、シャーシ100に確実に固定される。   First, when attaching the fixture 2 to the chassis 100, as in the first embodiment, the locking portion 20 of the fixture 2 is inserted into the attachment hole 101, and the step portions 25A and 25B are connected to the lower surface 100B of the chassis 100. Abut. Further, when the locking portion 20 penetrates the mounting hole 101, the contact pieces 130A and 130B come into contact with the upper surface 100A of the chassis 100 and press the upper surface 100A by its elastic force. At this time, the pressing operation parts 140A and 140B are positioned above the upper surface 100A with a gap from the upper surface 100A without pressing the upper surface 100A of the chassis 100 (see FIGS. 16, 19, and 22). 100 is sandwiched between the step portions 25A and 25B and the contact pieces 130A and 130B, and the fixture 2 is securely fixed to the chassis 100.

なお、シャーシ100に固定された固定具2に線材Sを保持させる方法、及びシャーシ100に固定された固定具2から線材Sを取外す方法は、実施の形態1と同様である。   The method for holding the wire S on the fixture 2 fixed to the chassis 100 and the method for removing the wire S from the fixture 2 fixed to the chassis 100 are the same as in the first embodiment.

また、固定具2をシャーシ100から取外す際は、使用者が指等で、押圧操作部140A及び140Bの突出部142A及び142Bを摘んで突出部142A及び142Bが互いに近づく方向に押圧する。この動作により、接続部22A及び22Bが内側に屈曲されて折り返し部23A及び23Bが縮小変形し、係止部20を取付孔101から簡単に抜脱することができる。   Further, when removing the fixing tool 2 from the chassis 100, the user holds the protrusions 142A and 142B of the pressing operation parts 140A and 140B with a finger or the like and presses the protrusions 142A and 142B closer to each other. By this operation, the connecting portions 22A and 22B are bent inward, and the folded portions 23A and 23B are reduced and deformed, so that the locking portion 20 can be easily removed from the mounting hole 101.

この時、押圧操作部140A及び140Bが、下方に変形しようとしても、押圧操作部140A及び140Bが当接片130A及び130Bに当接するため、押圧操作部140A及び140Bが下方に変形することはない。したがって、折り返し部23A及び23Bが不用意に広がることを防止することができ、係止部20をさらに簡単に取付孔101から抜脱することができる。   At this time, even if the pressing operation parts 140A and 140B are to be deformed downward, the pressing operation parts 140A and 140B are in contact with the contact pieces 130A and 130B, so that the pressing operation parts 140A and 140B are not deformed downward. . Therefore, the folded portions 23A and 23B can be prevented from spreading carelessly, and the locking portion 20 can be more easily removed from the mounting hole 101.

また、押圧操作部140A及び140Bの剛性等によって、押圧操作部140A及び140Bを、折り返し部23A及び23Bとの接続部分を支点として回転させようとする力が生じたとしても、第2の肉薄部34A及び34Bが、この力によって変形する。この変形により、押圧操作部140A及び140Bを回転させようとする力が吸収され、シャーシ100から固定具2を取外す際に、押圧操作部140A及び140Bの長さに関わらず、押圧操作部140A及び140Bの操作によって、係止部20をより一層縮小変形させやすくすることができる。   Further, even if a force to rotate the pressing operation parts 140A and 140B around the connection parts with the folded parts 23A and 23B occurs due to the rigidity of the pressing operation parts 140A and 140B, the second thin part 34A and 34B are deformed by this force. Due to this deformation, the force to rotate the pressing operation units 140A and 140B is absorbed, and when the fixture 2 is removed from the chassis 100, the pressing operation units 140A and 140B By the operation 140B, the locking portion 20 can be further reduced and deformed.

(実施の形態3)
次に、本発明の実施の形態3にかかる固定具について図面を参照して説明する。
(Embodiment 3)
Next, a fixture according to a third embodiment of the present invention will be described with reference to the drawings.

図23は、本発明の実施の形態3にかかる固定具の正面図であって、保持部を開放した状態を示す図、図24は、図23に示す固定具の左側面図、図25は、図24に示すXXV−XXV線に沿った断面図、図26は、図23に示す固定具の底面図、図27は、図23に示す固定具が取付けられるシャーシの斜視図、図28は、図23に示す固定具をシャーシに取付けた状態を示す正面図である。   FIG. 23 is a front view of the fixture according to the third embodiment of the present invention, showing a state in which the holding portion is opened, FIG. 24 is a left side view of the fixture shown in FIG. 23, and FIG. 24 is a cross-sectional view taken along line XXV-XXV shown in FIG. 24, FIG. 26 is a bottom view of the fixture shown in FIG. 23, FIG. 27 is a perspective view of a chassis to which the fixture shown in FIG. FIG. 24 is a front view showing a state where the fixture shown in FIG. 23 is attached to the chassis.

なお、実施の形態3では、実施の形態2で説明した部材と同様の部材には、同一の符号を付し、その詳細な説明は省略する。   In the third embodiment, the same members as those described in the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図23〜図26及び図28に示すように、実施の形態3にかかる固定具3の、実施の形態2にかかる固定具2と異なる主な点は、係止部120の形状と、押圧操作部240A及び240Bの形状である。   As shown in FIG. 23 to FIG. 26 and FIG. 28, the main points of the fixture 3 according to the third embodiment different from the fixture 2 according to the second embodiment are the shape of the locking portion 120 and the pressing operation. It is the shape of the parts 240A and 240B.

すなわち、固定具3の係止部120は、保持部10のベース11の下面略中央部から下方に向けて突設された支柱部121と、支柱部121の先端に弾性を有する屈曲可能な薄肉の接続部122A及び122Bを介して各々接続される折り返し部123A及び123Bと、を備えて構成されている。   That is, the locking portion 120 of the fixture 3 includes a support column 121 projecting downward from a substantially central portion of the lower surface of the base 11 of the holding unit 10, and a bendable thin wall having elasticity at the tip of the support column 121. , And folded portions 123A and 123B that are respectively connected via the connecting portions 122A and 122B.

支柱部121は、略円柱形状を有し、当該略円柱の長さ方向(上下方向)の中程部分の径を、両端部の径に対して短くし、当該中程部分に凹状に窪ませた構成を備えている。このように、支柱部121を略円柱形状に構成することで、固定具3に左右のずれが生じることを防止している。また、支柱部121の中程部分を凹状に窪ませることで、後に詳述するが、係止部120の折り返し部123A及び123Bが縮小変形する際に、折り返し部123A及び123Bと、第1の肉薄部124A及び124Bを、前記凹状に窪ませた部分に退避させることができる。したがって、折り返し部123A及び123Bを、より縮小させることができ(変形量を大きくすることができ)るため、固定部3をシャーシ200に形成された取付孔201(図27参照)に対し、さらに簡単に着脱させることができる。したがって、固定具3の取付け・取外しの操作性をさらに向上させることができる。また、折り返し部123A及び123Bを、より縮小させることができるため、折り返し部123Aまたは折り返し部123Bのいずれか一方のみが縮小変形する場合であっても、すなわち、押圧操作部240A(240B)が、一つであっても、固定具3の取付け・取外しを可能とすることができる。   The column part 121 has a substantially cylindrical shape, and the diameter of the middle part in the length direction (vertical direction) of the substantially column is made shorter than the diameters of both end parts, and is recessed in the middle part. It has a configuration. As described above, the support column 121 is configured to have a substantially cylindrical shape, thereby preventing the right and left shift of the fixture 3. Further, as will be described in detail later by recessing the middle part of the support column 121, when the folded parts 123A and 123B of the locking part 120 are deformed in a reduced size, the folded parts 123A and 123B, The thin portions 124A and 124B can be retracted to the recessed portion. Accordingly, since the folded portions 123A and 123B can be further reduced (the amount of deformation can be increased), the fixing portion 3 can be further removed from the mounting hole 201 (see FIG. 27) formed in the chassis 200. It can be easily attached and detached. Therefore, the operability of attaching / detaching the fixture 3 can be further improved. In addition, since the folded portions 123A and 123B can be further reduced, even when only one of the folded portion 123A or the folded portion 123B is reduced and deformed, that is, the pressing operation portion 240A (240B) Even if there is only one, it is possible to attach and detach the fixture 3.

また、支柱部121の先端面(下端面)は、接続部122A及び122Bよりも上方に窪んだ状態となっており、押圧操作部240A及び240Bの湾曲角度と、接続部122A及び122Bに対する支柱部121の先端面の窪み量(距離)を調節することで、シャーシ200の下面200Bから係止部120が突出する量が、なるべく少なくなるようにすることができる。   In addition, the front end surface (lower end surface) of the support column 121 is in a state of being depressed above the connection units 122A and 122B, the bending angle of the pressing operation units 240A and 240B, and the support column unit with respect to the connection units 122A and 122B. By adjusting the amount of depression (distance) of the front end surface 121, the amount by which the locking portion 120 protrudes from the lower surface 200B of the chassis 200 can be reduced as much as possible.

折り返し部123A及び123Bは、支柱部121に対し、互いに略180度位相した位置に設けられており、支柱部121から離れる方向に延出されている。また、この折り返し部123A及び123Bの先端側(自由端側)には、支柱部121側よりも肉薄な第1の肉薄部124A及び124Bが形成されている。これら第1の肉薄部124A及び124Bは、折り返し部123A及び123Bの支柱部121側よりも肉薄に形成されているため、折り返し部123A及び123Bに段差部分125A及び125Bを各々形成することになる。   The folded portions 123A and 123B are provided at positions that are substantially 180 degrees from each other with respect to the support column 121, and extend in a direction away from the support column 121. In addition, first thin portions 124A and 124B that are thinner than the column portion 121 side are formed on the front end side (free end side) of the folded portions 123A and 123B. Since the first thin portions 124A and 124B are formed thinner than the folded portions 123A and 123B on the support column 121 side, step portions 125A and 125B are formed in the folded portions 123A and 123B, respectively.

また、折り返し部123A及び123Bは、その上面128A及び128Bが斜め上方に向けた傾斜面となっている。一方、折り返し部123A及び123Bの下面129A及び129Bは、支柱部121の径方向に対して略平行な面となっており、段差部分125A及び125Bに対して略垂直な面となっている。また、下面129A及び129Bは、特に図26に示すように、略四角形を有しており、係止部120がシャーシ200に形成された取付孔201に挿入された際に、段差部分125Aと第1の肉薄部124Aとの境界部分と、段差部分125Bと第1の肉薄部124Bとの境界部分とが、後に詳述する取付孔201の当接壁202A及び202Bに各々当接するように構成されている。このように、前記境界部分と、取付孔201の当接壁202A及び202Bとを当接させることで、シャーシ200に取付けられた固定具3が回転することを防止する回り止めの役割を果たしている。   The folded portions 123A and 123B are inclined surfaces whose upper surfaces 128A and 128B are directed obliquely upward. On the other hand, the lower surfaces 129A and 129B of the folded portions 123A and 123B are substantially parallel to the radial direction of the support column 121, and are substantially perpendicular to the step portions 125A and 125B. In addition, the lower surfaces 129A and 129B have a substantially rectangular shape as shown in FIG. 26 in particular, and when the locking portion 120 is inserted into the mounting hole 201 formed in the chassis 200, the lower surface portions 129A and 129B The boundary portion between the first thin portion 124A and the boundary portion between the step portion 125B and the first thin portion 124B are in contact with the contact walls 202A and 202B of the mounting hole 201 described in detail later. ing. In this manner, the boundary portion and the contact walls 202A and 202B of the mounting hole 201 are brought into contact with each other, thereby serving as a detent for preventing the fixture 3 attached to the chassis 200 from rotating. .

押圧操作部240A及び240Bは、折り返し部123A及び123Bの上端部より略直角方向に屈曲して外方に延出した板状部241A及び241Bを有し、板状部241A及び241Bの先端には、上方に向けて突出した突出部242A及び242Bが形成されている。この押圧操作部240A及び240Bは、図26に示すように、底面から見て互いに反対の向きとなるように配設されている。なお、板状部241A及び241Bは、実施の形態2と同様に、保持部10を閉じた際(図28参照)に開口している面に対し、略垂直な方向に延出しており、保持部10に保持される線材S(図15参照)の挿入方向に対し、略垂直な方向に延出している。   The pressing operation portions 240A and 240B have plate-like portions 241A and 241B that are bent in a substantially right angle direction from the upper end portions of the folded-back portions 123A and 123B and extend outward, and at the tips of the plate-like portions 241A and 241B. Projections 242A and 242B projecting upward are formed. As shown in FIG. 26, the pressing operation parts 240A and 240B are disposed so as to be opposite to each other when viewed from the bottom surface. As in the second embodiment, the plate-like portions 241A and 241B extend in a direction substantially perpendicular to the surface opened when the holding portion 10 is closed (see FIG. 28). It extends in a direction substantially perpendicular to the insertion direction of the wire S held by the portion 10 (see FIG. 15).

この押圧操作部240A及び240Bは、特に、図28に示すように、固定具3をシャーシ200に固定した際に、シャーシ200の上面200Aと隙間をおいて配置され、使用者が指等で突出部242A及び242Bを摘んで支柱部121に向けて押圧することで、接続部122A及び122Bが内側に屈曲して、係止部120の折り返し部123A及び123Bを互いに近づく方向に移動させる。この時、前述したように、折り返し部123A及び123Bと、第1の肉薄部124A及び124Bを、支柱部121に形成された凹状に窪ませた部分に退避させることができるため、係止部120は、一層縮小変形することになる。この結果、固定具3の取付け・取外しの操作性をさらに向上させることができ、また、折り返し部123Aまたは折り返し部123Bのいずれか一方のみを縮小変形させる構造であっても、固定具3の取付け・取外しを可能とすることができる。   As shown in FIG. 28, the pressing operation parts 240A and 240B are arranged with a gap from the upper surface 200A of the chassis 200 when the fixture 3 is fixed to the chassis 200, and the user protrudes with a finger or the like. By pinching the parts 242A and 242B and pressing them toward the column part 121, the connecting parts 122A and 122B are bent inward, and the folded parts 123A and 123B of the locking part 120 are moved in a direction approaching each other. At this time, as described above, since the folded portions 123A and 123B and the first thin portions 124A and 124B can be retracted to the recessed portion formed in the support column 121, the locking portion 120 is provided. Will be further reduced and deformed. As a result, the operability of attaching / detaching the fixture 3 can be further improved, and the fixture 3 can be attached even if only one of the folded portion 123A or the folded portion 123B is contracted and deformed.・ Can be removed.

次に、固定具3が取付けられるシャーシ200について説明する。図27及び図28に示すように、このシャーシ200には、固定具3の係止部120が挿入される取付孔201が形成されている。この取付孔201は、平面視で略円形の円形孔203と、円形孔203に対し互いに略180度位相した位置に形成されると共に、円形孔203に連通した略四角形の角孔204A及び204Bから構成されている。角孔204A及び204Bの円形孔203から離れた側を画定する側壁は、係止部120が取付孔201に挿入された際に、段差部分125Aと第1の肉薄部124Aとの境界部分と、段差部分125Bと第1の肉薄部124Bとの境界部分が各々当接する当接壁202A及び202Bとなっている。そして、前述したように、前記境界部分と、取付孔201の当接壁202A及び202Bとが当接することで、シャーシ200に取付けられた固定具3の回り止めを行っている。   Next, the chassis 200 to which the fixture 3 is attached will be described. As shown in FIGS. 27 and 28, the chassis 200 is formed with a mounting hole 201 into which the locking portion 120 of the fixture 3 is inserted. The mounting hole 201 is formed at a position that is substantially 180 degrees in phase with each other with respect to the circular hole 203 and the substantially circular square holes 204 </ b> A and 204 </ b> B communicating with the circular hole 203. It is configured. The side walls defining the sides of the square holes 204A and 204B away from the circular hole 203 have a boundary portion between the stepped portion 125A and the first thin portion 124A when the locking portion 120 is inserted into the mounting hole 201, and The boundary portions between the stepped portion 125B and the first thin portion 124B are contact walls 202A and 202B that contact each other. As described above, the fixing portion 3 attached to the chassis 200 is prevented from rotating by the contact between the boundary portion and the contact walls 202A and 202B of the attachment hole 201.

次に、実施の形態3にかかる固定具3の具体的動作について説明する。   Next, a specific operation of the fixture 3 according to the third embodiment will be described.

先ず、固定具3をシャーシ200に取付ける際は、固定具3の段差部分125A及び125Bが、取付孔201の当接壁202A及び202Bに対し、各々対向するようにして係止部120を取付孔201内に挿入させる。この時、係止部120は、押圧操作部240A及び240Bの突出部242A及び242Bを摘んで支柱部121に向けて押圧することで、接続部122A及び122Bが内側に屈曲させ、折り返し部123A及び123Bを互いに近づく方向に移動させて、係止部120を縮小変形させた状態とし、取付孔201内に挿入させてもよい。   First, when attaching the fixture 3 to the chassis 200, the locking portion 120 is attached to the attachment hole so that the stepped portions 125A and 125B of the fixture 3 face the contact walls 202A and 202B of the attachment hole 201, respectively. Insert into 201. At this time, the locking part 120 grips the protrusions 242A and 242B of the pressing operation parts 240A and 240B and presses them toward the column part 121, so that the connection parts 122A and 122B are bent inward, and the folded parts 123A and 123A and 123B may be moved in a direction approaching each other so that the locking portion 120 is reduced and deformed and inserted into the mounting hole 201.

係止部120が取付孔201内に挿入されると、段差部分125Aと第1の肉薄部124Aとの境界部分と、段差部分125Bと第1の肉薄部124Bとの境界部分とが、取付孔201の当接壁202A及び202Bに各々当接すると共に、段差部分125A及び125Bの一部がシャーシ200の下面200Bに当接する。このように、前記境界部分が当接壁202A及び202Bに各々当接するため、シャーシ200に固定具3を取付ける際に、固定具3が回転することを防止することができ、且つ固定具3をシャーシ200に取付けた後も、固定具3が回転することを防止することができる。したがって、固定具3を常に一定の方向で配設することができる。   When the locking portion 120 is inserted into the attachment hole 201, the boundary portion between the step portion 125A and the first thin portion 124A and the boundary portion between the step portion 125B and the first thin portion 124B are attached to the attachment hole. Each of the step portions 125 </ b> A and 125 </ b> B contacts the lower surface 200 </ b> B of the chassis 200. As described above, since the boundary portion abuts against the abutting walls 202A and 202B, when the fixture 3 is attached to the chassis 200, the fixture 3 can be prevented from rotating, and the fixture 3 can be Even after being attached to the chassis 200, it is possible to prevent the fixture 3 from rotating. Therefore, the fixture 3 can always be arranged in a certain direction.

また、係止部120が、取付孔201を貫通すると、当接片130A及び130Bがシャーシ200の上面200Aに当接して、その弾性力により上面200Aを押圧する。この時、押圧操作部240A及び240Bは、シャーシ200の上面200Aを押圧することなく、上面200Aと隙間をおいて上面200Aの上方に位置するが、シャーシ200は、段差部分125A及び125Bと、段差部分125A及び125Bと第1の肉薄部124A及び124Bとの境界部分と、当接片130A及び130Bと、によって挟持された状態となり、固定具3は、シャーシ200に確実に固定される。   Further, when the locking portion 120 passes through the mounting hole 201, the contact pieces 130A and 130B come into contact with the upper surface 200A of the chassis 200 and press the upper surface 200A by its elastic force. At this time, the pressing operation parts 240A and 240B are positioned above the upper surface 200A with a gap from the upper surface 200A without pressing the upper surface 200A of the chassis 200. However, the chassis 200 has a step difference between the step portions 125A and 125B. The fixing member 3 is securely fixed to the chassis 200 by being sandwiched between the boundary portions between the portions 125A and 125B and the first thin portions 124A and 124B and the contact pieces 130A and 130B.

なお、シャーシ200に固定された固定具3に線材Sを保持させる方法、及びシャーシ200に固定された固定具3から線材Sを取外す方法は、実施の形態1及び2と同様である。   The method for holding the wire S on the fixture 3 fixed to the chassis 200 and the method for removing the wire S from the fixture 3 fixed to the chassis 200 are the same as in the first and second embodiments.

また、固定具3をシャーシ200から取外す際は、使用者が指等で、押圧操作部240A及び240Bの突出部242A及び242Bを摘んで突出部242A及び242Bが互いに近づく方向に押圧する。この時、折り返し部123A及び123Bと、第1の肉薄部124A及び124Bを、支柱部121に形成された凹状に窪ませた部分に退避させることができるため、係止部120は、一層縮小変形することになる。このため、固定具3の取付け・取外しの操作性をさらに向上させることができる。   Further, when the fixing tool 3 is removed from the chassis 200, the user grips the protrusions 242 </ b> A and 242 </ b> B of the pressing operation parts 240 </ b> A and 240 </ b> B with a finger or the like, and presses the protrusions 242 </ b> A and 242 </ At this time, since the folded portions 123A and 123B and the first thin portions 124A and 124B can be retracted to the recessed portions formed in the support column 121, the locking portion 120 is further reduced and deformed. Will do. For this reason, the operativity of attachment / detachment of the fixture 3 can be further improved.

なお、実施の形態3では、固定具3が取付けられるシャーシ200に形成される取付孔201を、円形孔203とこれに連通した2つの角孔204A及び204Bから構成した場合について説明したが、これに限らず、シャーシ200に形成される取付孔は、段差部分125Aと第1の肉薄部124Aとの境界部分、及び、段差部分125Bと第1の肉薄部124Bとの境界部分に対し当接して固定具3の回り止めを行うことが可能な当接壁(平坦な面)が形成されていれば、特に限定されるものではなく、例えば、円形孔を中心として十字状(互いに約90度移相した位置)に角孔が形成されてもよい。また、シャーシ200に形成される取付孔は、平面視で略四角形の角孔であってもよい。   In the third embodiment, the case where the mounting hole 201 formed in the chassis 200 to which the fixture 3 is mounted is configured by the circular hole 203 and the two square holes 204A and 204B communicating with the circular hole 203 is described. However, the mounting hole formed in the chassis 200 is in contact with the boundary portion between the step portion 125A and the first thin portion 124A and the boundary portion between the step portion 125B and the first thin portion 124B. There is no particular limitation as long as a contact wall (flat surface) capable of preventing the fixing device 3 from rotating is formed. For example, a cross shape (about 90 degrees between each other) is formed around a circular hole. A square hole may be formed at a compatible position). Further, the mounting hole formed in the chassis 200 may be a substantially square hole in plan view.

また、本発明にかかる固定具3の係止部120は、その下面129A及び129Bが、底面視で略四角形となるように構成することで、シャーシ200の取付孔201に形成された平坦な面(当接壁202A及び202B)に当接可能な平坦な面を形成したが、これに限らず、係止部120は、取付孔201に形成された平坦な面に当接可能な平坦な面を有しており、係止部120が取付孔201に挿入された際に、係止部120に形成された平坦な面が取付孔201に形成された平坦な面に当接して回り止めされれば、他の形状を有していてもよい。   Moreover, the latching | locking part 120 of the fixing tool 3 concerning this invention comprises the flat surface formed in the attachment hole 201 of the chassis 200 by comprising the lower surfaces 129A and 129B so that it may become a substantially square shape in bottom view. Although the flat surface which can contact | abut to (contact wall 202A and 202B) was formed, not only this but the latching | locking part 120 is a flat surface which can contact | abut to the flat surface formed in the attachment hole 201. When the locking portion 120 is inserted into the mounting hole 201, the flat surface formed in the locking portion 120 abuts against the flat surface formed in the mounting hole 201 and is prevented from rotating. Any other shape may be used.

なお、本実施の形態1〜3で説明した保持部10は、ベース11及び第1の保持部12Aの長さ、被係合部15の位置等が若干異なっているが、その基本的な形状は共通しているため、これらの違いについての詳細な説明は省略した。   The holding portion 10 described in the first to third embodiments is slightly different in the length of the base 11 and the first holding portion 12A, the position of the engaged portion 15 and the like, but its basic shape. Since they are in common, detailed explanation of these differences was omitted.
