Description

この発明は、被取付体を取付用雄ねじ体により取り付ける部位に前記取付用雄ねじ体の雄ねじ部と組み合わされる雌ねじ部を有する保持用部材が備えられた樹脂材製の取付体に関するものである。 The present invention relates to a resin-made mounting body in which a holding member having a female screw portion combined with a male screw portion of the mounting male screw body is provided at a site where the mounted body is mounted by a mounting male screw body.

樹脂成形筐体などの樹脂材製の取付体では、小ねじや六角ボルトなどの取付用雄ねじ体によって部品（半導体素子応用装置用の回路基板など）等の被取付体を取付体に取り付ける部位には、インサートナットなどのねじ取付用雄ねじ体が持つ雄ねじ部と組み合わされる雌ねじ部を有する金属製の保持用部材が一般的に使用されている。このような異種材料の部材が一体成形などによってインサートされた樹脂材製品をリサイクルに供するためには、異種材料部材である金属製の保持用部材を樹脂材から容易に分離できるようにする必要がある。この目的のために、従来の樹脂成形筐体などの樹脂材製の取付体では、インサートナットの外周部に雄ねじ部を形成している（例えば、特許文献１参照。)。
実開平０６−０５９０２２号公報（第４−６頁、第１−４図） In the mounting body made of resin material such as a resin-molded housing, the mounting body such as a component (circuit board for semiconductor device application equipment) is attached to the mounting body by a male screw body such as a small screw or hexagon bolt. In general, a metal holding member having a female screw portion combined with a male screw portion of a male screw body for screw attachment such as an insert nut is generally used. In order to recycle a resin material product in which such dissimilar material members are inserted by integral molding or the like, it is necessary to easily separate the metal holding member which is a dissimilar material member from the resin material. is there. For this purpose, in a conventional attachment body made of a resin material such as a resin molded housing, an external thread portion is formed on the outer peripheral portion of the insert nut (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 06-059022 (page 4-6, Fig. 1-4)

前述した従来技術による樹脂成形筐体などの取付体では、インサートナット（保持用部材の一種である。）の外周部に雄ねじ部を形成するようにし、取付体などの廃棄時に樹脂材製の取付体とは異なる材料である金属材が用いられたインサートナットを取付体から分離することができるよう配慮されている。ところで、取付体に用いられる樹脂材には、各種の樹脂材の中で総合的な機械特性が優れていて金属材に似た性質を持つＡＢＳ材，ポリカーボネート材などのエンジニアリング・プラスチック材と呼ばれている樹脂材が一般的に採用されている。このエンジニアリング・プラスチック材は、樹脂材を構成している高分子化合物の分子構造に関する分類としては、いずれのものも熱可塑性樹脂材に属している。
この熱可塑性樹脂材では、一定の大きさの力が加わっているとき、時間の経過とともに材料の変形が増大していく現象（クリープ現象と呼ばれている。）が、金属材と対比して顕著に現れることが知られている。そうしてこのクリープ現象は、高温になるほど顕著になることも知られている。従来技術による樹脂成形筐体などの取付体は、その製作の当初では取付体の製作時に樹脂材に発生する成形時収縮によってインサートナットと樹脂材の間には十分な締付力が働くので、インサートナットは樹脂材に確実に保持される。これにより、被取付体を取付用雄ねじ体によりインサートナットに締め付けることで、被取付体をインサートナットを介して取付体に取り付けることができる。 In the mounting body such as a resin molded housing according to the above-described prior art, a male screw portion is formed on the outer peripheral portion of the insert nut (a kind of holding member), and the mounting made of a resin material when the mounting body is discarded. Consideration is given so that an insert nut using a metal material different from the body can be separated from the mounting body. By the way, the resin materials used for the mounting body are called engineering plastic materials such as ABS materials and polycarbonate materials, which have excellent overall mechanical properties among various resin materials and have properties similar to metal materials. Resin materials are generally adopted. These engineering plastic materials all belong to thermoplastic resin materials as classifications related to the molecular structure of the polymer compound constituting the resin material.
In this thermoplastic resin material, when a certain amount of force is applied, the phenomenon that the deformation of the material increases with the passage of time (called the creep phenomenon) is compared with that of a metal material. It is known to appear prominently. Thus, it is also known that this creep phenomenon becomes more prominent at higher temperatures. A mounting body such as a resin molded housing according to the prior art has a sufficient tightening force between the insert nut and the resin material due to shrinkage at the time of molding that occurs in the resin material when the mounting body is manufactured. The insert nut is securely held by the resin material. Thereby, a to-be-attached body can be attached to an attachment body via an insert nut by fastening an to-be-attached body to an insert nut with the external thread body for attachment.

しかしながら、取付体を長時間使用し続けると、インサートナットと樹脂材の間の締付力がクリープ現象によって低減されるので、被取付体の点検などのために被取付体を取付体から取り外そうとするときにインサートナットが取付用雄ねじ体と一緒に回ってしまい、インサートナットが樹脂材から抜け出てしまう虞れがある。また、このことを回避するためにインサートナットを接着法などの適宜の方法によって取付体に強固に固着させた場合には、取付体の廃棄処理時に、インサートナットの取付体からの分離が困難になり、取付体のリサイクル処理にとって問題となる。さらに、多数のインサートナットが用いられる取付体の場合には、インサートナットの取付体からの取り外し作業に長時間を要するとの不都合もある。したがってこの発明の目的は、高いリサイクル処理性と保持用部材の長期間安定した固定との両立が可能な樹脂材製の取付体を提供することにある。 However, if the mounting body is used for a long time, the clamping force between the insert nut and the resin material is reduced by the creep phenomenon, so the mounting body is removed from the mounting body for inspection of the mounting body. At that time, the insert nut may rotate together with the mounting male screw body, and the insert nut may come out of the resin material. In addition, in order to avoid this, when the insert nut is firmly fixed to the mounting body by an appropriate method such as an adhesion method, it is difficult to separate the insert nut from the mounting body during disposal of the mounting body. This is a problem for the recycling process of the mounting body. Furthermore, in the case of a mounting body in which a large number of insert nuts are used, there is a disadvantage that it takes a long time to remove the insert nut from the mounting body. Accordingly, an object of the present invention is to provide an attachment body made of a resin material capable of achieving both high recyclability and stable long-term fixing of a holding member.

FIG. 3 is a cross-sectional view including a partially broken portion in the AA cross section of FIG. 1 in the assembled state of the product of the present invention shown in FIG. 1 to 3, reference numeral 1 denotes an attachment body made of a resin material according to the present invention, 9 denotes an attachment body attached to the attachment body 1, and 99 denotes a male screw for attaching the attachment body 9 to the attachment body 1. An external thread body for attachment having a portion 98. In this case, the mounted body 9 is illustrated as a flat member, the mounting male screw body 99 is illustrated as a metal small screw, and the mounting male screw body 99 is generally combined with a small screw. The flat washer 97 and the spring washer 96, which are often used, are illustrated as being used together.

取付体１には、例えば、従来技術による樹脂材製の取付体の場合と同様に、ＡＢＳ材，ポリカーボネート材などのエンジニアリング・プラスチック材が採用されている。この取付体１は、被取付体９を取付体１に取り付けるための１個または複数個の取付部２を要所に備えると共に、各取付部２には保持用部材３と固定部４とを備えている。保持用部材３は、例えば、正六角形の外形を持つと共にその正六角形の中心部に雌ねじ部３１が形成されている標準部材である金属製の六角ナットに、その正六角形のそれぞれの辺に対応する部位に取付用雄ねじ体９９の挿入される側の端面３３に向かって傾斜するテーパー面部３２を形成したものである。
固定部４は、取付用雄ねじ体９９を挿入できる径の貫通孔を持つ蛇の目状部４１と、保持用部材３のテーパー面部３２が持ついずれかのテーパー面と当接し合えるように蛇の目状部４１に形成された当接部４２とを有する金属材製の部材であり、この事例の場合には、当接部４２は舌状の面形状と先端部ほど薄い楔状の断面形状を持つと共に，蛇の目状部４１の外径部分に１対が形成されている。各取付部２には、保持用部材３を装填するための挿入穴２１が備えられている。挿入穴２１の穴形状は保持用部材３を取付用雄ねじ体９９の挿入される方向から着脱自在でかつ回転不可能なように装填するために、例えば、保持用部材３の正六角形の外形と相似形にしている。また、保持用部材３の取付用雄ねじ体９９の挿入される方向に関する挿入位置を定めるための支持部として、この事例の場合には、挿入穴２１に底部２２が備えられている。 For example, an engineering plastic material such as an ABS material or a polycarbonate material is used for the mounting body 1 as in the case of a mounting body made of a resin material according to the prior art. The mounting body 1 includes one or a plurality of mounting portions 2 for mounting the mounted body 9 to the mounting body 1 at key points, and each mounting portion 2 includes a holding member 3 and a fixing portion 4. I have. The holding member 3 has, for example, a regular hexagonal outer shape and a metal hexagonal nut which is a standard member in which a female screw portion 31 is formed at the center of the regular hexagon, and corresponds to each side of the regular hexagon. The taper surface part 32 which inclines toward the end surface 33 by the side where the male screw body 99 for attachment is inserted is formed in the site | part to perform.
The fixing portion 4 has a serpentine-shaped portion 41 having a through hole having a diameter into which the mounting male screw body 99 can be inserted, and a serpentine-shaped portion 41 so as to come into contact with any one of the tapered surfaces of the tapered surface portion 32 of the holding member 3. In this case, the contact portion 42 has a tongue-like surface shape and a wedge-shaped cross-sectional shape that is thinner toward the tip, and has a serpentine shape. A pair is formed on the outer diameter portion of the shaped portion 41. Each mounting portion 2 is provided with an insertion hole 21 for loading the holding member 3. The hole shape of the insertion hole 21 is, for example, a regular hexagonal outer shape of the holding member 3 in order to load the holding member 3 so as to be detachable and non-rotatable from the direction in which the male screw body 99 is inserted. It has a similar shape. In this case, the insertion hole 21 is provided with a bottom 22 as a support for determining the insertion position in the direction in which the male screw body 99 for attachment of the holding member 3 is inserted.

なお、有底穴２３は必要に応じて設けられる取付用雄ねじ体９９に対する逃げ穴である。被取付体９の取付用雄ねじ体９９が装填される部位には、取付用雄ねじ体９９を挿入するための貫通孔９１が形成されている。この事例の場合には、この貫通孔９１は固定部４の主要部も収容するようにしており、このために、固定部４の当接部４２，４２の主要部が収容される部位には逃げ溝９２，９２が形成されている。この発明による取付体１では、保持用部材３を各取付部２の挿入穴２１にまず装填する。そうすると、挿入穴２１の正六角形のそれぞれの辺に対応する周囲壁部と保持用部材３のテーパー面部３２との間に隙間ができる。この隙間に当接部４２，４２を挿入させて固定部４を打ち込み、固定部４を取付部２に装着する。
その際、当接部４２が楔のように作用して当接部４２の舌状の面に対して垂直方向に打ち込み力に対して極めて大きな力が生じ、この力が当接部４２と接する保持用部材３および取付部２に加わることで、当接部４２と保持用部材３との間，および当接部４２と取付部２との間には大きな面圧力が与えられことになる。この結果、保持用部材３には前記面圧力と相互間の摩擦係数との積に従う外力に対する抵抗力が得られるので、保持用部材３は大きな外力に対してその固定状態を維持できることになる。なお、当接部４２，４２を挿入させる隙間の位置は、被取付体９の取付体１への装着時に、当接部４２，４２が貫通孔９１の逃げ溝９２，９２に収容されるように選定される。固定部４が打ち込みにより取付部２に装着された状態で、被取付体９を取付用雄ねじ体９９などを用いて取付体１に装着する。 The bottomed hole 23 is a relief hole for the mounting male screw body 99 provided as necessary. A through hole 91 for inserting the mounting male screw body 99 is formed in a portion of the mounted body 9 where the mounting male screw body 99 is loaded. In this case, the through-hole 91 also accommodates the main part of the fixed part 4, and for this reason, the part where the main parts of the contact parts 42, 42 of the fixed part 4 are accommodated Escape grooves 92 and 92 are formed. In the attachment body 1 according to the present invention, the holding member 3 is first loaded into the insertion holes 21 of the attachment portions 2. Then, a gap is formed between the peripheral wall portion corresponding to each side of the regular hexagon of the insertion hole 21 and the tapered surface portion 32 of the holding member 3. The abutting portions 42 and 42 are inserted into the gap to drive the fixing portion 4, and the fixing portion 4 is attached to the attachment portion 2.
At that time, the abutting portion 42 acts like a wedge, and a very large force is generated with respect to the driving force in a direction perpendicular to the tongue-like surface of the abutting portion 42, and this force contacts the abutting portion 42. By applying to the holding member 3 and the attachment portion 2, a large surface pressure is applied between the contact portion 42 and the holding member 3 and between the contact portion 42 and the attachment portion 2. As a result, the holding member 3 can obtain a resistance force against an external force according to the product of the surface pressure and the coefficient of friction between them, so that the holding member 3 can maintain its fixed state against a large external force. Note that the positions of the gaps into which the contact portions 42 and 42 are inserted are such that the contact portions 42 and 42 are accommodated in the escape grooves 92 and 92 of the through hole 91 when the mounted body 9 is mounted on the mounting body 1. Selected. In a state where the fixed portion 4 is mounted on the mounting portion 2 by driving, the mounted body 9 is mounted on the mounting body 1 using the mounting male screw body 99 or the like.

その際、被取付体９と取付部２の保持用部材３が装填される側の端面２４とが当接された後も、取付用雄ねじ体９９を保持用部材３に締め込むと、取付用雄ねじ体９９を締め込むのにしたがって保持用部材３が被取付体９に近づく方向に移動するので、当接部４２，４２は前記隙間に食い込むことになり、保持用部材３と取付部２とはより強固に固定される。この状態で被取付体９の取付体１への装着作業は終了である。取付体１では、固定部４の取付体１への最初の装着時に際しては、固定部４の当接部４２，４２の先端部と挿入穴２１の底部２２との間に、所要長さの間隔Ｌ（図３を参照。）が存在するように当接部４２，４２の長さ寸法が設定されている。
そうして、この発明の取付体１の場合にも従来技術の場合と同様に、固定部４の当接部４２，４２と取付部２の挿入穴２１の周囲壁部との間に働く面圧力に関して、取付部２の樹脂材のクリープ現象によるその値の低減の発生が考えられるが、取付体１では被取付体の点検時などを利用して固定部４の再打ち込みを行うことで保持用部材３と取付部２との固定状態を元通りに回復できるので、保持用部材３と取付部２との固定状態を長期間安定して保持することができる。また、取付体１の廃棄処理時には、マイナスドライバーなどの工具を、固定部４の蛇の目状部４１と取付部２の端面２４との間にこじ入れて固定部４を取付部２から抜き取ることで、取付体１に対する異種材料製の固定部４および保持用部材３を、取付体１から容易に取り去ることができる。
『実施の形態２』図４はこの発明の実施の形態の異なる例による取付体を関連部材と共に示す要部の展開斜視図であり、図５の（ａ）は図４に示したこの発明品の組立状態の図４のＢ―Ｂ断面における断面図であり、（ｂ）は図５の（ａ）における要部のＣ−Ｃ断面図である。なお、後記する「実施の形態３」の項以降を含む以下の説明においては、図１〜図３に示したこの発明による取付体１と同一部分には同じ符号を付しその説明を省略する。図４，図５において、１Ａは、図１〜図３に示したこの発明による取付体１に対し、取付部２，保持用部材３に替えてそれぞれ取付部２Ａ，保持用部材５を用いると共に単独部材としての固定部４を使用しないようにしたことを除いては、使用材料も同一のこの発明の取付体である。保持用部材５は、例えば、正六角形の外形を持つと共にその正六角形の中心部に雌ねじ部３１が形成されている標準部材である金属製の六角ナットである。 At that time, when the mounting male screw body 99 is tightened into the holding member 3 even after the mounted body 9 and the end surface 24 of the mounting portion 2 on the side where the holding member 3 is loaded are brought into contact with each other, As the male screw body 99 is tightened, the holding member 3 moves in a direction approaching the mounted body 9, so that the abutting portions 42, 42 bite into the gap, and the holding member 3, the mounting portion 2, Is more firmly fixed. In this state, the mounting work of the mounted body 9 to the mounting body 1 is completed. In the attachment body 1, when the fixing portion 4 is first attached to the attachment body 1, a required length is provided between the front end portions of the contact portions 42 and 42 of the fixing portion 4 and the bottom portion 22 of the insertion hole 21. The length dimensions of the contact portions 42 and 42 are set so that there is an interval L (see FIG. 3).
Thus, in the case of the attachment body 1 of the present invention, as in the case of the prior art, the surface acting between the abutting portions 42 and 42 of the fixing portion 4 and the peripheral wall portion of the insertion hole 21 of the attachment portion 2. Regarding the pressure, the value may be reduced due to the creep phenomenon of the resin material of the mounting portion 2, but the mounting body 1 is held by re-injecting the fixing portion 4 during inspection of the mounted body. Since the fixed state of the member 3 and the mounting portion 2 can be restored to the original state, the fixed state of the holding member 3 and the mounting portion 2 can be stably held for a long time. Further, during disposal of the attachment body 1, a tool such as a flat-blade screwdriver is inserted between the serpentine-shaped portion 41 of the fixing portion 4 and the end surface 24 of the attachment portion 2 to remove the fixing portion 4 from the attachment portion 2. The fixing portion 4 and the holding member 3 made of different materials with respect to the mounting body 1 can be easily removed from the mounting body 1.
[Embodiment 2] FIG. 4 is an exploded perspective view of a main part showing an attachment body according to a different example of the embodiment of the present invention together with related members, and FIG. 5 (a) is the product of the present invention shown in FIG. FIG. 6 is a cross-sectional view taken along the line BB in FIG. 4 in the assembled state, and FIG. 5B is a cross-sectional view taken along the line CC in FIG. 5A. In the following description including the section “Embodiment 3” to be described later, the same parts as those of the mounting body 1 according to the present invention shown in FIGS. . 4A and 5B, 1A uses the mounting portion 2A and the holding member 5 in place of the mounting portion 2 and the holding member 3 for the mounting body 1 according to the present invention shown in FIGS. Except that the fixed part 4 as a single member is not used, the material used is the same mounting body of the present invention. The holding member 5 is, for example, a metal hexagon nut that is a standard member having a regular hexagonal outer shape and having a female screw portion 31 formed at the center of the regular hexagon.

各取付部２Ａには、保持用部材５を装填するための正六角形状の挿入穴２１の，相対峙する辺の内の１対の辺に対応する部位に、固定部４８，４８が形成されている。それぞれの固定部４８は、例えば、固定部４８が形成される取付部２Ａの円形の外形の側面にほぼ直交する方向に弾性的に撓むことができると共に，底部２２の付近から端面２４の方向に向かって延びるアーム部４８ａと、アーム部４８ａの先端部の内側に形成された顎部４８ｂとを持っている。顎部４８ｂの位置は底部２２と顎部４８ｂとの間に保持用部材５を挟み込めるように設定されている。被取付体９Ａの取付用雄ねじ体９９が装填される部位には、取付用雄ねじ体９９を挿入するための貫通孔９１Ａが形成されている。この事例の場合には、この貫通孔９１Ａは固定部４８の一部も収容するようにしており、このために、固定部４８の顎部４８ｂ，４８ｂが収容される部位には逃げ溝９３，９３が形成されている。 In each attachment portion 2A, fixing portions 48, 48 are formed at portions corresponding to a pair of sides of the opposite hexagonal insertion holes 21 for loading the holding member 5 therein. ing. Each fixing portion 48 can be elastically bent in a direction substantially perpendicular to the side surface of the circular outer shape of the mounting portion 2A on which the fixing portion 48 is formed, for example, and the direction from the vicinity of the bottom portion 22 to the end surface 24 Arm portion 48a extending toward the top and a jaw portion 48b formed inside the tip portion of the arm portion 48a. The position of the jaw part 48b is set so that the holding member 5 can be sandwiched between the bottom part 22 and the jaw part 48b. A through-hole 91A for inserting the mounting male screw body 99 is formed in a portion of the mounting body 9A where the mounting male screw body 99 is loaded. In this case, the through hole 91A also accommodates a part of the fixing portion 48. For this reason, in the portion where the jaw portions 48b, 48b of the fixing portion 48 are accommodated, the escape grooves 93, 93 is formed.

そうして、この逃げ溝９３，９３の径方向の寸法は、顎部４８ｂ部分の固定部４８，４８の径方向の外面を嵌め込めるように設定されている。この発明による取付体１Ａでは、保持用部材５を固定部４８，４８のアーム部４８ａ，４８ａを押し拡げたうえで、各取付部２Ａの挿入穴２１にまず装填する。保持用部材５は挿入穴２１と底部２２および固定部４８，４８のスナップフィットとにより取付体１Ａに保持される。この状態で、被取付体９Ａを取付用雄ねじ体９９などを用いて取付体１Ａに装着する。その際、被取付体９Ａと取付部２Ａの端面２４とが当接された後も取付用雄ねじ体９９を保持用部材５に締め込むと、取付用雄ねじ体９９を締め込むのにしたがって保持用部材５が被取付体９Ａに近づく方向に移動し、保持用部材５の被取付体９Ａ側の端面３３が固定部４８の顎部４８ｂ，４８ｂにしっかりと当接されるので、この状態で被取付体９Ａの取付体１Ａへの装着作業は終了である。 Thus, the radial dimensions of the clearance grooves 93 and 93 are set so that the radial outer surfaces of the fixed portions 48 and 48 of the jaw portion 48b can be fitted. In the attachment body 1A according to the present invention, the holding member 5 is first loaded into the insertion holes 21 of the attachment portions 2A after the arms 48a and 48a of the fixing portions 48 and 48 are expanded. The holding member 5 is held by the attachment body 1 A by the insertion hole 21, the bottom portion 22, and the snap fit of the fixing portions 48 and 48. In this state, the mounted body 9A is mounted on the mounting body 1A using the mounting male screw body 99 or the like. At this time, when the mounting male screw body 99 is tightened into the holding member 5 even after the mounted body 9A and the end surface 24 of the mounting portion 2A are brought into contact with each other, the holding male screw body 99 is tightened as the mounting male screw body 99 is tightened. The member 5 moves in a direction approaching the attached body 9A, and the end surface 33 on the attached body 9A side of the holding member 5 is firmly brought into contact with the jaw portions 48b, 48b of the fixing portion 48. The mounting work of the mounting body 9A to the mounting body 1A is completed.

この時、被取付体９Ａの貫通孔９１Ａの逃げ溝９３，９３が固定部４８，４８を拡がらないように外面側から抑えているので、保持用部材５が顎部４８ｂ，４８ｂから外れることは無い。そうして、この発明の取付体１Ａの場合には、保持用部材５は挿入穴２１の周囲壁部によりその径方向が、また、底部２２および固定部４８，４８の顎部４８ｂ，４８ｂによりその厚さ方向を保持されるので、保持用部材５は取付部２Ａの所定の位置に安定に保持される。そうして、この発明の取付体１Ａの場合にも従来技術の場合と同様に、固定部４８，４８に働く引張力に関して、取付部２Ａの樹脂材のクリープ現象によるその低減の発生が考えられるが、取付体１Ａでは被取付体の点検時などを利用して、例えば取付用雄ねじ体９９の増し締めを行うことで保持用部材５の取付部２Ａへの固定状態を元通りに回復できるので、保持用部材５と取付部２Ａとの固定状態を長期間安定して保持することができる。 At this time, since the escape grooves 93 and 93 of the through hole 91A of the attached body 9A suppress the fixing portions 48 and 48 from expanding from the outer surface side, the holding member 5 is detached from the jaw portions 48b and 48b. There is no. Thus, in the case of the attachment body 1A of the present invention, the holding member 5 is arranged in the radial direction by the peripheral wall portion of the insertion hole 21, and by the bottom portion 22 and the jaw portions 48b, 48b of the fixing portions 48, 48. Since the thickness direction is held, the holding member 5 is stably held at a predetermined position of the mounting portion 2A. Thus, in the case of the attachment body 1A of the present invention, as in the case of the prior art, the reduction of the tensile force acting on the fixing portions 48, 48 due to the creep phenomenon of the resin material of the attachment portion 2A can be considered. However, in the mounting body 1A, the fixing state of the holding member 5 to the mounting portion 2A can be restored to its original state by, for example, retightening the mounting male screw body 99 using the inspection of the mounted body. The fixed state between the holding member 5 and the mounting portion 2A can be stably held for a long period of time.

また、取付体１Ａの廃棄処理時には、一般的なスナップフィットされた部材の取り外し作業の場合と同様な方法によって固定部４８，４８を押し拡げたうえで、取付体１Ａに対する異種材料製の保持用部材５を、取付体１Ａから容易に取り去ることができる。この時、固定部４８，４８は被取付体９Ａの貫通孔９１Ａの逃げ溝９３，９３によって抑えられる状態から解放されているので、固定部４８，４８を押し拡げる作業は容易である。
『実施の形態３』図６はこの発明の実施の形態の異なる例による取付体を関連部材と共に示す要部の展開斜視図であり、図７の（ａ）は図６に示したこの発明品の組立状態の図６のＤ―Ｄ断面における断面図であり、（ｂ）は図７の（ａ）における要部のＲ矢視図である。図６，図７において、１Ｂは、図１〜図３に示したこの発明による取付体１に対し、取付部２，保持用部材３および固定部４に替えて、それぞれ取付部２Ｂ，保持用部材５および固定部６を用いることを除いては、使用材料も同一のこの発明の取付体である。保持用部材５は、前記「実施の形態２」による取付体１Ａが持つ保持用部材５と全く同一であり、正六角形の外形を持つと共にその正六角形の中心部に雌ねじ部３１が形成されている標準部材である金属製の六角ナットである。 Further, at the time of disposal of the attachment body 1A, the fixing portions 48 and 48 are expanded by the same method as in the case of a general snap-fit member removal operation, and then the attachment body 1A is made of a different material. The member 5 can be easily removed from the attachment body 1A. At this time, since the fixing portions 48 are released from a state where they are restrained by the escape grooves 93 93 of the through hole 91A of the mounted body 9A, the work of expanding the fixing portions 48 is easy.
[Embodiment 3] FIG. 6 is an exploded perspective view of a main part showing an attachment body according to a different example of the embodiment of the present invention together with related members, and FIG. 7 (a) is the product of the present invention shown in FIG. FIG. 7 is a cross-sectional view taken along the line DD in FIG. 6 in the assembled state, and FIG. 7B is a view taken along the arrow R of the main part in FIG. 6 and 7, reference numeral 1 B denotes a mounting portion 2 B and a holding portion, respectively, instead of the mounting portion 2, the holding member 3, and the fixing portion 4 with respect to the mounting body 1 according to the present invention shown in FIGS. 1 to 3. Except for the use of the member 5 and the fixing portion 6, the material used is the same mounting body of the present invention. The holding member 5 is exactly the same as the holding member 5 included in the mounting body 1A according to the “second embodiment”, has a regular hexagonal outer shape, and has a female screw portion 31 formed at the center of the regular hexagon. It is a metal hex nut which is a standard member.

各取付部２Ｂには、例えば、保持用部材５を装填するための正六角形状の挿入穴２１の，相対峙する辺の内の１対の辺に対応する部位の外形部分に、端面２４から案内用溝２６，２６と係止用溝２７，２７とが形成されている。案内用溝２６と係止用溝２７とは共に固定部６の後記する係止用突起部６７と嵌り合う溝寸法を持ち、案内用溝２６が端面２４から形成され、係止用溝２７は案内用溝２６に連続させて図７（ｂ）に例示したように、この事例の場合には端面２４とほぼ平行させて形成される。固定部６は、適宜の樹脂材や金属材などを用いて製作され、取付部２Ｂの外形よりも大きい外径および取付用雄ねじ体９９を挿入できる内径を持つ円筒状体を基本形状とし、その一方の端面６１に回転防止用突起部６２，６２が形成されている。
また、固定部６の他方の端面６４からは取付部２Ｂの外形と嵌り合う径と底面６６とを持つ有底穴６５が形成され、この有底穴６５の他方の端面６４に近接する部位の内面部には、案内用溝２６および係止用溝２７と嵌り合うことができる係止用突起部６７，６７が形成されている。なお、固定部６の端面６１に形成された溝６３は、固定部６の取付部２Ｂへの着脱作業時などの際にマイナスドライバーのような工具の使用を可能にするために必要に応じて設けられる。被取付体９Ｂの取付用雄ねじ体９９が装填される部位には、取付用雄ねじ体９９を挿入するための貫通孔９１Ｂが形成されている。この事例の場合には、この貫通孔９１Ｂは固定部６の回転防止用突起部６２，６２も収容するようにしており、このために、回転防止用突起部６２，６２が収容される部位には欠除部である逃げ溝９４，９４が形成されている。 Each mounting portion 2B has, for example, an outer peripheral portion of a portion corresponding to a pair of sides of the opposite hexagonal insertion holes 21 for loading the holding member 5 from the end face 24. Guide grooves 26 and 26 and locking grooves 27 and 27 are formed. Both the guide groove 26 and the locking groove 27 have a groove size that fits with a locking projection 67 described later of the fixed portion 6, the guide groove 26 is formed from the end surface 24, and the locking groove 27 is As illustrated in FIG. 7B, the guide groove 26 is formed so as to be substantially parallel to the end surface 24. The fixing portion 6 is manufactured using an appropriate resin material, metal material, or the like, and has a cylindrical shape with an outer diameter larger than the outer shape of the mounting portion 2B and an inner diameter into which the mounting male screw body 99 can be inserted. One end face 61 is formed with anti-rotation protrusions 62 and 62.
Further, a bottomed hole 65 having a bottom surface 66 having a diameter that fits the outer shape of the mounting portion 2 B is formed from the other end surface 64 of the fixed portion 6, and a portion of the bottomed hole 65 adjacent to the other end surface 64 is formed. Locking projections 67 and 67 that can fit into the guide groove 26 and the locking groove 27 are formed on the inner surface. The groove 63 formed in the end surface 61 of the fixed portion 6 is used as necessary to enable the use of a tool such as a flat-blade screwdriver when attaching / detaching the fixed portion 6 to / from the mounting portion 2B. Provided. A through-hole 91B for inserting the mounting male screw body 99 is formed at a portion of the mounted body 9B where the mounting male screw body 99 is loaded. In this case, the through hole 91B also accommodates the anti-rotation protrusions 62 and 62 of the fixed portion 6. For this reason, the through-hole 91B is provided at a portion where the anti-rotation protrusions 62 and 62 are accommodated. Are formed with relief grooves 94, 94 which are notched portions.

この発明による取付体１Ｂでは、保持用部材５を各取付部２Ｂの挿入穴２１にまず装填する。続いて固定部６を、係止用突起部６７，６７を案内用溝２６，２６に嵌め合わせて取付部２Ｂにセットし、係止用突起部６７，６７を案内用溝２６，２６に沿わせて底面６６が端面２４に当接されるまで押し込み、さらに、係止用突起部６７，６７を係止用溝２７，２７に沿わせてその端部付近まで回動させて、保持用部材５を取付部２Ｂに保持させる。この状態で、被取付体９Ｂを取付用雄ねじ体９９などを用いて取付体１Ｂに装着する。その際、保持用部材５の被取付体９Ｂ側の端面３３が固定部６の底面６６に当接された後も取付用雄ねじ体９９を保持用部材５に締め込むと、取付用雄ねじ体９９を締め込むのにしたがって保持用部材５が被取付体９Ｂに近づく方向に移動し、やがて固定部６の端面６１が被取付体９Ｂにしっかりと当接されるので、この状態で被取付体９Ｂの取付体１Ｂへの装着作業は終了である。 In the attachment body 1B according to the present invention, the holding member 5 is first loaded into the insertion holes 21 of the attachment portions 2B. Subsequently, the fixing portion 6 is fitted to the guide grooves 26, 26 with the locking projections 67, 67 and set to the mounting portion 2B, and the locking projections 67, 67 are set along the guide grooves 26, 26. Then, the bottom surface 66 is pushed in until it comes into contact with the end surface 24. Further, the locking projections 67, 67 are rotated along the locking grooves 27, 27 to the vicinity of the end portion, thereby holding the holding member. 5 is held by the mounting portion 2B. In this state, the mounted body 9B is mounted on the mounting body 1B using the mounting male screw body 99 or the like. At this time, when the mounting male screw body 99 is tightened into the holding member 5 even after the end surface 33 of the holding member 5 on the mounted body 9B side is in contact with the bottom surface 66 of the fixing portion 6, the mounting male screw body 99 is secured. As the fastening member 5 is tightened, the holding member 5 moves in a direction approaching the attached body 9B, and the end surface 61 of the fixed portion 6 is brought into firm contact with the attached body 9B before long. In this state, the attached body 9B The mounting operation to the mounting body 1B is completed.

この時、固定部６の回転防止用突起部６２，６２が被取付体９Ｂの貫通孔９１Ｂの逃げ溝９４，９４に嵌り込んでいるので、固定部６が回動することはなく、したがって、保持用部材５は取付部２Ｂの所定の位置に安定に保持される。そうして、この発明の取付体１Ｂの場合には、保持用部材５は挿入穴２１の周囲壁部によりその径方向が、また、取付部２Ｂの底部２２および固定部６の底面６６によりその厚さ方向を保持される。そうして、この取付体１Ｂの場合のクリープ現象の発生の主な対象は、樹脂材製とされた場合の固定部６の底面６６と保持用部材５の被取付体９Ｂ側の端面３３との間に働く面圧力や、係止用突起部６７，６７に働く剪断力などに関する。
固定部６と保持用部材５の間に働く面圧力や係止用突起部６７，６７に働く剪断力などに関して、固定部６の樹脂材のクリープ現象によるその低減が発生した場合には、取付体１Ｂでは被取付体の点検時などを利用して、例えば取付用雄ねじ体９９の増し締めを行うことで保持用部材５の取付部２Ｂへの固定状態を元通りに回復できるので、保持用部材５と取付部２Ｂとの固定状態を長期間安定して保持することができる。また、取付体１Ｂの廃棄処理時には、固定部６を装着時の逆の手順で取付部２Ｂから取り外すことで、取付体１Ｂに対する異種材料製の保持用部材５を、取付体１Ｂから容易に取り去ることができる。なお、固定部６が取付体１Ｂに対して異種材料製の場合であっても、取付体１Ｂから容易に取り去ることができることは言うまでもない。これ等の作業時に、固定部６は被取付体９Ｂの貫通孔９１Ｂの逃げ溝９４，９４によって抑えられる状態から解放されているので、固定部６を取付部２Ｂから取り外す作業は容易である。 At this time, since the protrusions 62 and 62 for preventing rotation of the fixing portion 6 are fitted in the escape grooves 94 and 94 of the through hole 91B of the mounted body 9B, the fixing portion 6 does not rotate. The holding member 5 is stably held at a predetermined position of the mounting portion 2B. Thus, in the case of the attachment body 1B of the present invention, the holding member 5 is arranged in the radial direction by the peripheral wall portion of the insertion hole 21, and by the bottom portion 22 of the attachment portion 2B and the bottom surface 66 of the fixing portion 6. The thickness direction is retained. Thus, the main object of the occurrence of the creep phenomenon in the case of the mounting body 1B is that the bottom surface 66 of the fixing portion 6 and the end surface 33 of the holding member 5 on the mounted body 9B side when the resin body is used. And the shearing force acting on the locking projections 67 and 67.
When the surface pressure acting between the fixing portion 6 and the holding member 5 and the shearing force acting on the locking projections 67 and 67 are reduced due to the creep phenomenon of the resin material of the fixing portion 6, mounting is performed. In the body 1B, the fixing state of the holding member 5 to the mounting portion 2B can be restored to its original state by, for example, retightening the mounting male screw body 99 using the inspection of the mounted body. The fixed state of the member 5 and the attachment portion 2B can be stably maintained for a long time. Further, when the mounting body 1B is discarded, the holding member 5 made of a different material with respect to the mounting body 1B can be easily removed from the mounting body 1B by removing the fixing portion 6 from the mounting section 2B in the reverse procedure of mounting. be able to. Needless to say, even if the fixing portion 6 is made of a different material from the attachment body 1B, it can be easily removed from the attachment body 1B. During these operations, the fixing portion 6 is released from a state in which the fixing portion 6 is restrained by the escape grooves 94, 94 of the through hole 91B of the attached body 9B, so that the operation of removing the fixing portion 6 from the attachment portion 2B is easy.

「実施の形態１」〜「実施の形態３」における前述の説明では、取付体１〜取付体１Ｂが備える保持用部材３または５は正六角形の外形を持つとしてきたが、これに限定されるものではなく、例えば、正四角形や六角形などの適宜の多角形であってもよい。また、取付体１が備える固定部４は、１対の当接部４２を有するとしてきたが、これに限定されるものではなく、例えば、当接部４２の個数は１個でも、また、保持用部材３の外形形状に合わせた適宜の個数であってもよいものである。

Except that the fixed portion 4 is not used, the material used is the same mounting body of the present invention. The holding member 7 is manufactured using an appropriate metal material, resin material, or the like. For example, a female screw portion 71 that fits with the male screw portion 98 of the mounting male screw body 99 is formed at substantially the center of a rectangular thin plate material. The wider end portions are bent to form bent portions 72 and 72.

この屈曲部７２，７２はこの事例の場合の保持用部材７が取付部２Ｃから脱落するのを防止する脱落防止部であり、屈曲部７２，７２で取付部２Ｃの柱状の外形の側面部に保持用部材７が係止されるように設定されている。各取付部２Ｃには、取付用雄ねじ体９９を装填するための挿入穴２８が、例えば有底穴として端面２４から形成され、また、保持用部材７が着脱自在に装填される装填用孔２９が、例えば取付部２Ｃを横断する貫通孔として形成されている。この事例の場合の装填用孔２９は、その孔を挿入穴２８の中心軸線Ｘ−Ｘ〔図８（ａ）に一点鎖線で示す。〕に対してほぼ直交させて形成されている。また、この装填用孔２９は、孔の断面形状を屈曲部７２，７２を含む保持用部材７が通過できると共に、取付用雄ねじ体９９の挿入方向に対する反対方向に関して保持用部材７が移動できるようにするために、矩形状とされている。被取付体９Ｃの取付用雄ねじ体９９が装填される部位には、取付用雄ねじ体９９を挿入するための貫通孔９１Ｃが形成されている。 The bent portions 72 and 72 are drop-off preventing portions that prevent the holding member 7 in this case from falling off the mounting portion 2C, and the bent portions 72 and 72 are provided on the side portions of the columnar outer shape of the mounting portion 2C. The holding member 7 is set to be locked. Each mounting portion 2C is formed with an insertion hole 28 for loading the mounting male screw body 99 from the end surface 24 as a bottomed hole, for example, and a loading hole 29 into which the holding member 7 is detachably loaded. For example, it is formed as a through hole that crosses the mounting portion 2C. In the case of this example, the loading hole 29 is indicated by a one-dot chain line in FIG. 8A. ] Substantially orthogonal to the above. Further, the loading hole 29 allows the holding member 7 including the bent portions 72 and 72 to pass through the cross-sectional shape of the hole and allows the holding member 7 to move in the direction opposite to the insertion direction of the mounting male screw body 99. In order to achieve this, it has a rectangular shape. A through hole 91 C for inserting the mounting male screw body 99 is formed at a portion of the mounted body 9 C where the mounting male screw body 99 is loaded.

被取付体９Ｃの場合には前述した被取付体９〜被取付体９Ｂの場合とは異なり、この貫通孔９１Ｃは取付用雄ねじ体９９を挿入できることだけでよいので、例えば、単純な円形状に形成されている。この発明による取付体１Ｃでは、まず保持用部材７を装填用孔２９から各取付部２Ｃに装填し、屈曲部７２，７２を取付部２Ｃの外形の側面部に嵌め合わせて保持用部材７を取付部２Ｃに係止する。図８（ｂ）および図８（ｄ）はこの状態を示している。この状態で、被取付体９Ｃを取付用雄ねじ体９９などを用いて取付体１Ｃに装着する。その際、取付用雄ねじ体９９の雄ねじ部９８を保持用部材７の雌ねじ部７１に締め込むと、雄ねじ部９８を締め込むのにしたがって保持用部材７が被取付体９Ｃに近づく方向に移動し、やがて保持用部材７の被取付体９Ｃ側の面が装填用孔２９の被取付体９Ｃ側の内面に当接される。 In the case of the attached body 9C, unlike the case of the attached body 9 to the attached body 9B described above, the through-hole 91C only needs to be able to insert the male screw body 99 for attachment, and thus, for example, in a simple circular shape. Is formed. In the mounting body 1C according to the present invention, the holding member 7 is first loaded into the mounting portions 2C from the loading holes 29, and the bent portions 72 and 72 are fitted to the side surface portions of the outer shape of the mounting portion 2C. Lock to the mounting portion 2C. FIG. 8B and FIG. 8D show this state. In this state, the mounted body 9C is mounted on the mounting body 1C using the mounting male screw body 99 or the like. At this time, when the male screw portion 98 of the mounting male screw body 99 is tightened to the female screw portion 71 of the holding member 7, the holding member 7 moves in a direction approaching the attached body 9C as the male screw portion 98 is tightened. Eventually, the surface of the holding member 7 on the mounted body 9C side comes into contact with the inner surface of the loading hole 29 on the mounted body 9C side.

図８（ａ）はこの状態を示している。この状態で取付部２Ｃの端面２４が被取付体９Ｃにしっかりと当接されるので、被取付体９Ｃの取付体１Ｃへの装着作業は終了である。この時、保持用部材７が装填用孔２９に嵌り込んでおり、保持用部材７の両側面が装填用孔２９の側部内面と嵌め合わされているので、保持用部材７が回動することはなく、したがって、保持用部材７は取付部２Ｃの所定の位置に安定に保持される。そうして、この取付体１Ｃの場合のクリープ現象の発生の主な対象は保持用部材７の被取付体９Ｃ側の面と、取付部２Ｃの装填用孔２９の被取付体９Ｃ側の内面との間に働く面圧力に関する。
取付部２Ｃと保持用部材７の間に働く面圧力に関して、取付部２Ｃの樹脂材のクリープ現象によるその低減が発生した場合には、取付体１Ｃの場合でも取付体１Ｂなどの場合と同様に、被取付体の点検時などを利用して、例えば取付用雄ねじ体９９の増し締めを行うことで保持用部材７の取付部２Ｃへの固定状態を元通りに回復できるので、保持用部材７と取付部２Ｃとの固定状態を長期間安定して保持することができる。また、取付体１の廃棄処理時には、保持用部材７を装填時の逆の手順で取付部２Ｃから取り外すことで、取付体１Ｃに対する異種材料製の保持用部材７を、取付体１Ｃから容易に取り去ることができる。 FIG. 8A shows this state. In this state, the end surface 24 of the mounting portion 2C is firmly in contact with the mounted body 9C, so that the mounting work of the mounted body 9C on the mounting body 1C is completed. At this time, since the holding member 7 is fitted in the loading hole 29 and both side surfaces of the holding member 7 are fitted to the inner side surface of the loading hole 29, the holding member 7 is rotated. Therefore, the holding member 7 is stably held at a predetermined position of the mounting portion 2C. Thus, the main object of the occurrence of the creep phenomenon in the case of the mounting body 1C is the surface on the mounted body 9C side of the holding member 7 and the inner surface on the mounted body 9C side of the loading hole 29 of the mounting portion 2C. The surface pressure acting between
When the surface pressure acting between the mounting portion 2C and the holding member 7 is reduced by the creep phenomenon of the resin material of the mounting portion 2C, the case of the mounting body 1C is the same as the case of the mounting body 1B. The fixing state of the holding member 7 to the mounting portion 2C can be restored to its original state by, for example, retightening the mounting male screw body 99 by using the inspection of the mounted body. And the fixing portion 2C can be stably held for a long time. Further, when the mounting body 1 is disposed of, the holding member 7 can be easily detached from the mounting body 1C by removing the holding member 7 from the mounting portion 2C in the reverse procedure of loading. Can be removed.

「実施の形態４」における前述の説明では、保持用部材７が有する脱落防止部は屈曲部であるとしてきたが、これに限定されるものではなく、例えば、切り起こし，角部の折り曲げなどの適宜の方法によって形成されたものであってもよい。また、保持用部材７が有する脱落防止部は保持用部材７の装填用孔２９へ挿入される際の先端部および後端部のそれぞれに設けられるとしてきたが、これに限定されるものではなく、例えば、挿入穴２８を利用して係止されるように，挿入穴２８に対応する部位に設けても、また、取付部２Ｃの外形の側面部と挿入穴２８の部位とを組み合わせて係止されるようにしてもよい。さらにまた、装填用孔２９は挿入穴２８の中心軸線Ｘ−Ｘに対してほぼ直交させて形成されるとしてきたが、これに限定されるものではなく、例えば、装填用孔２９は挿入穴２８の中心軸線Ｘ−Ｘに対して適宜の角度で交叉させて形成してもよいものである。 In the above description of “Embodiment 4”, the drop-off preventing portion of the holding member 7 is a bent portion. However, the present invention is not limited to this, and examples thereof include cutting and raising, bending of corner portions, and the like. It may be formed by an appropriate method. In addition, the drop-off prevention portion of the holding member 7 has been provided at each of the front end portion and the rear end portion when being inserted into the loading hole 29 of the holding member 7, but is not limited thereto. For example, even if it is provided at a portion corresponding to the insertion hole 28 so as to be locked using the insertion hole 28, the side surface portion of the outer shape of the mounting portion 2C and the portion of the insertion hole 28 are combined. It may be stopped. Furthermore, the loading hole 29 has been formed so as to be substantially orthogonal to the central axis XX of the insertion hole 28, but the present invention is not limited to this. For example, the loading hole 29 is formed in the insertion hole 28. It may be formed by crossing at an appropriate angle with respect to the central axis XX.

「実施の形態１〜４」における前述の説明では、取付体１，取付体１Ａ，取付体１Ｃの取付部２，２Ａ，２Ｃは円柱状の外形を持つとしてきたが、これに限定されるものではなく、例えば、多角形などの適宜の外形を持つものであってもよいものである。 In the above description in “Embodiments 1 to 4,” the attachment parts 1, 2A, and 2C of the attachment body 1, the attachment body 1A, and the attachment body 1C have a cylindrical outer shape. However, the present invention is not limited to this. Instead, it may have an appropriate outer shape such as a polygon.
