Description

本発明は、ソケットに関するものである。 The present invention relates to a socket.

ソケットは、ネジ、ボルト及びナットなどの締結部材を駆動するためのものである。ソケットの嵌め部は、その寸法および形状が一定であり、寸法および輪郭がそれに合う締結部材だけを嵌めることが可能である。このため、工場では、各寸法のソケットを用意することが必要であり、コストが高くなる。また、異なる寸法および形状を有する複数のソケットは収納しにくく、携帯が不便である。このような問題を解決するために、あるメーカーは、二種の寸法を持つソケットを開発し、更に、三種以上の寸法を持つソケットを開発した。このようなソケットは、例えば、特許文献１（台湾発明Ｉ５７６２０８号）及び特許文献２（米国特許ＵＳ５１５７９９５号）などにおいて提案されている。 Sockets are used to drive fastening members such as screws, bolts, and nuts. The fitting part of a socket has a fixed size and shape, and only fastening members with matching sizes and contours can be fitted into it. This requires factories to prepare sockets of each size, which increases costs. In addition, multiple sockets with different sizes and shapes are difficult to store and inconvenient to carry. To solve this problem, one manufacturer developed a socket with two sizes, and further developed a socket with three or more sizes. Such sockets have been proposed, for example, in Patent Document 1 (Taiwan Invention No. I576208) and Patent Document 2 (US Patent No. US5157995).

このようなソケットは、最も外側にありかつ寸法が一定である嵌め部を基準とし、その他の寸法がより小さい嵌め部を上記最も外側の嵌め部の内部に入れた構造を有している。使用時には、締結部材による押付により、小さい寸法を持つ嵌め部を後退させて、締結部材がそれに合う嵌め部と結合する。すなわち、このようなソケットの構造は、複数の嵌め部を後退させる技術を採用する。 Such sockets have a structure in which the outermost fitting portion, which has a fixed dimension, is used as a reference, and other fitting portions with smaller dimensions are placed inside the outermost fitting portion. When in use, the fitting portion with the smaller dimension is pushed back by the fastening member, and the fastening member connects with the fitting portion that matches it. In other words, the structure of such sockets employs a technique for retracting multiple fitting portions.

台湾発明Ｉ５７６２０８号公報Taiwan Invention Publication No. I576208 米国特許ＵＳ５１５７９９５号公報US Patent No. US5157995 台湾実用新案Ｍ３４８６６６号公報Taiwan Utility Model Publication No. M348666

しかしながら、上記のような構造によれば、多種の寸法を持つ嵌め部および多種の弾力を有するバネが必要となり、そしてソケットの内部には、多種の移動規制機構を設けることにより部材の離脱を防止することが必要であるため、各部材を合わせるための精度が要請され、加工が難しくなり、組付け作業がしにくくなり、作製コストが高くなる。 However, with the above structure, fittings with various dimensions and springs with various elasticities are required, and various movement restriction mechanisms must be provided inside the socket to prevent parts from coming apart. This requires high precision in fitting the various parts together, making processing difficult, assembly work difficult, and manufacturing costs high.

もう一つのタイプのソケットの構造は、例えば特許文献３（台湾実用新案Ｍ３４８６６６号）において提案されている。このようなソケットは、最も外側にありかつ寸法が一定であるケースを基準とし、ケースの内部に複数の円筒状部材を重なるように入れた構造を有している。これにより、嵌め部の寸法が多種となる。各円筒状部材には、長さが互いに異なるガイド溝がそれぞれ設けられており、スライド可能な複数の横ロッドにより各円筒状部材が連結される。使用時には、利用しようとする円筒状部材をケースから押し出す。 Another type of socket structure is proposed, for example, in Patent Document 3 (Taiwan Utility Model M348666). This type of socket is based on a case that is the outermost and has constant dimensions, and has a structure in which multiple cylindrical members are placed inside the case so that they overlap. This allows for a wide variety of fitting dimensions. Each cylindrical member is provided with guide grooves of different lengths, and the cylindrical members are connected by multiple slidable horizontal rods. When in use, the cylindrical member to be used is pushed out of the case.

しかしながら、上記のソケットによれば、各部材を合わせるための精度が要請され、加工が難しくなり、例えばガイド溝の長さの設計、側辺の位置決め溝の位置の選定、及び連結ロッドの細かい構造の設計などは難しい。そして、使用時には、ソケットを回転することによるトルクが横ロッドに集中しやすいため、利用回数が多くなると変形しやすい。 However, the socket described above requires high precision in fitting each component, making processing difficult; for example, it is difficult to design the length of the guide groove, select the position of the side positioning groove, and design the detailed structure of the connecting rod. Furthermore, when in use, the torque caused by rotating the socket tends to concentrate on the side rod, so it is prone to deformation if used frequently.

本発明の主な目的は、内部の構造を簡素化することが可能であると共に、全体の体積を大幅に減少することが可能であり、操作が便利となるソケットを提供することにある。 The main objective of the present invention is to provide a socket that can simplify the internal structure, significantly reduce the overall volume, and is easy to operate.

以下、本発明の実施の形態を図面に基づいて説明する。 The following describes an embodiment of the present invention with reference to the drawings.

図１から図７を参照する。本発明の一実施形態に係るソケットは、筒状の第１部材１と、筒状の第２部材２と、筒状の第３部材３と、を備える。なお、以下においては、第１被駆動部材９１、第２被駆動部材９２および第３被駆動部材９３がそれぞれ、締結部材（より具体的には、ボルト）である場合について説明する。また、以下においては、図１に示すソケットにおける第２部材２および第３部材３のそれぞれの位置を初期位置とする。本実施形態では、第２部材２の初期位置では、第２部材２が後述する結合部１１から離れる方向に移動することが規制され、第３部材３の初期位置では、第３部材３が後述する係合部１１に近付く方向に移動することが規制される。 Refer to Figs. 1 to 7. A socket according to one embodiment of the present invention includes a cylindrical first member 1, a cylindrical second member 2, and a cylindrical third member 3. In the following, a case will be described in which the first driven member 91, the second driven member 92, and the third driven member 93 are fastening members (more specifically, bolts). In the following, the positions of the second member 2 and the third member 3 in the socket shown in Fig. 1 are defined as initial positions. In this embodiment, in the initial position of the second member 2, the second member 2 is restricted from moving in a direction away from the connecting portion 11 described later, and in the initial position of the third member 3, the third member 3 is restricted from moving in a direction approaching the engaging portion 11 described later.

第１部材１は、互いに対向する、結合部１１と、第１嵌め部１２と、を備える。本実施形態では、第１部材１の軸方向において、第１嵌め部１２から結合部１１に向かう方向が第１方向に対応し、結合部１１から第１嵌め部１２に向かう方向が第２方向に対応する。本実施形態では、第１部材１の軸方向において、第１部材１の一方の端部に結合部１１が設けられ、第１部材１の他方の端部に第１嵌め部１２が設けられている。結合部１１は、図示しない駆動工具（例えば、トルクレンチ、エアポンプ、電動工具など）に、直接または間接的に取り付けられる。本実施形態では、駆動工具によって結合部１１が回転駆動されることによって、第１部材１、第２部材２および第３部材３が一体的に回転する。第１嵌め部１２には、所定の寸法の第１被駆動部材９１を嵌めることができる。上記駆動工具によって第１部材１を回転駆動することによって、第１嵌め部１２に嵌められた第１被駆動部材９１を回転させることができる。第２部材２は、第１部材１に差し込まれており、所定の寸法の第２被駆動部材９２を嵌めることができる第２嵌め部２１を備える。第２嵌め部２１に第２被駆動部材９２を嵌めた状態で、上記駆動工具によって第１部材１を回転駆動することによって、第２嵌め部２１に嵌められた第２被駆動部材９２を回転させることができる。第２嵌め部２１は第１嵌め部１２に収容される。図１および図２に示すように、第２嵌め部２１は、第１嵌め部１２に対して、第１部材１の軸方向に移動することができる。言い換えると、第２嵌め部２１は、第１嵌め部１２に対して、結合部１１に近接する方向（第１方向）および結合部１１から離隔する方向（第２方向）へ移動することが可能である。図１、図２および図６に示すように、初期位置の第２嵌め部２１（第２部材２）を結合部１１側に移動させることによって、第１嵌め部１２に第１被駆動部材９１を嵌めることができる。これにより、第１被駆動部材９１を回転駆動することが可能になる。 The first member 1 has a connecting portion 11 and a first fitting portion 12 that face each other. In this embodiment, in the axial direction of the first member 1, the direction from the first fitting portion 12 toward the connecting portion 11 corresponds to the first direction, and the direction from the connecting portion 11 toward the first fitting portion 12 corresponds to the second direction. In this embodiment, in the axial direction of the first member 1, the connecting portion 11 is provided at one end of the first member 1, and the first fitting portion 12 is provided at the other end of the first member 1. The connecting portion 11 is directly or indirectly attached to a driving tool (e.g., a torque wrench, an air pump, a power tool, etc.) not shown. In this embodiment, the first member 1, the second member 2, and the third member 3 rotate integrally as a result of the connecting portion 11 being rotated and driven by the driving tool. A first driven member 91 of a predetermined dimension can be fitted into the first fitting portion 12. The first member 1 is rotated by the driving tool, so that the first driven member 91 fitted in the first fitting portion 12 can be rotated. The second member 2 is inserted into the first member 1 and includes a second fitting portion 21 into which a second driven member 92 of a predetermined dimension can be fitted. With the second driven member 92 fitted in the second fitting portion 21, the second driven member 92 fitted in the second fitting portion 21 can be rotated by rotating the first member 1 with the driving tool. The second fitting portion 21 is accommodated in the first fitting portion 12. As shown in FIG. 1 and FIG. 2, the second fitting portion 21 can move in the axial direction of the first member 1 relative to the first fitting portion 12. In other words, the second fitting portion 21 can move in a direction approaching the coupling portion 11 (first direction) and in a direction moving away from the coupling portion 11 (second direction) relative to the first fitting portion 12. As shown in Figures 1, 2, and 6, the first driven member 91 can be fitted into the first fitting portion 12 by moving the second fitting portion 21 (second member 2) from the initial position toward the connecting portion 11. This makes it possible to rotate the first driven member 91.

第３部材３は、第１部材１の外側に嵌められており、第３被駆動部材９３を嵌めることができる第３嵌め部３１を備える。図１および図３に示すように、第３嵌め部３１は、第１嵌め部１２に対して、第１部材１の軸方向に移動することができる。第３嵌め部３１は、第１嵌め部１２に対して、結合部１１から離れる方向および結合部１１に近接する方向へ移動することが可能である。図１、図３および図７に示すように、初期位置の第３嵌め部３１（第３部材３）を結合部１１から離れる方向に移動させることによって、第３嵌め部３１の一部を、第１嵌め部１２から突出させることができる。これにより、第３嵌め部３１に第３被駆動部材９３を嵌めることができる。第３嵌め部３１に第３被駆動部材９３を嵌めた状態で、上記駆動工具によって第１部材１を回転駆動することによって、第３嵌め部３１に嵌められた第３被駆動部材９３を回転させることができる。第１嵌め部１２、第２嵌め部２１及び第３嵌め部３１の内径は、互いに異なる。なお、本明細書において嵌め部の内径とは、嵌め部の軸方向から見て嵌め部に内接する円の直径のことをいう。 The third member 3 is fitted to the outside of the first member 1 and has a third fitting portion 31 into which the third driven member 93 can be fitted. As shown in FIG. 1 and FIG. 3, the third fitting portion 31 can move in the axial direction of the first member 1 relative to the first fitting portion 12. The third fitting portion 31 can move in a direction away from the connecting portion 11 and a direction toward the connecting portion 11 relative to the first fitting portion 12. As shown in FIG. 1, FIG. 3 and FIG. 7, by moving the third fitting portion 31 (third member 3) from the initial position in a direction away from the connecting portion 11, a part of the third fitting portion 31 can be protruded from the first fitting portion 12. This allows the third driven member 93 to be fitted into the third fitting portion 31. With the third driven member 93 fitted in the third fitting portion 31, the first member 1 can be rotated by the driving tool to rotate the third driven member 93 fitted in the third fitting portion 31. The inner diameters of the first fitting portion 12, the second fitting portion 21, and the third fitting portion 31 are different from one another. In this specification, the inner diameter of the fitting portion refers to the diameter of a circle inscribed in the fitting portion when viewed from the axial direction of the fitting portion.

上記の内側の差し込み及び外側の嵌めという結合方式により、第２嵌め部２１及び第３嵌め部３１は、中央に位置し動かない第１嵌め部１２を基準として、独立に内側（結合部１１側）へ後退し、又は外側（第１部材１の軸方向における外側）へ伸びることができる。このため、第２嵌め部２１又は第３嵌め部３１を選んで移動させるときに、第２嵌め部２１と第３嵌め部３１とが干渉したり、連動したりすることはない。したがって、ユーザーは、所望の寸法の嵌め部を迅速に選ぶことができる。 The above-mentioned connection method of inserting the inside and fitting the outside allows the second fitting portion 21 and the third fitting portion 31 to independently recede inward (toward the connecting portion 11) or extend outward (outward in the axial direction of the first member 1) based on the first fitting portion 12, which is located in the center and does not move. Therefore, when the second fitting portion 21 or the third fitting portion 31 is selected and moved, the second fitting portion 21 and the third fitting portion 31 do not interfere with each other or move together. Therefore, the user can quickly select a fitting portion of the desired size.

また、操作を簡単化し、ユーザーが前記ソケットを直観的に利用することが可能となるために、前記ソケットの使用方法は下記のステップを含む。まず、回転させようとする被駆動部材（第１被駆動部材９１、第２被駆動部材９２又は第３被駆動部材９３）の寸法に応じて、第１嵌め部１２、第２嵌め部２１及び第３嵌め部３１の中で一つを選ぶ。例えば、第１嵌め部１２を選んだ場合には、初期位置の第２嵌め部２１（第２部材２）を結合部１１に近接する方向へ押し付ける。これにより、第２嵌め部２１が第１嵌め部１２に対して内側に後退（結合部１１側へ移動）する。第１嵌め部１２内において第２嵌め部２１が移動することによって空いた空間に第１被駆動部材９１を嵌めて、第１被駆動部材９１を駆動する。なお、第２嵌め部２１を選んだ場合には、第２嵌め部２１に第２被駆動部材９２を嵌めて、第２被駆動部材を駆動する。第３嵌め部３１を選んだ場合には、初期位置の第３嵌め部３１（第３部材３）を結合部１１から離れる方向へ引くことにより、第３嵌め部３１が第１嵌め部１２から突出する。そして、第３嵌め部３１に第３被駆動部材９３を嵌めて、第３被駆動部材９３を駆動する。 In addition, in order to simplify the operation and enable the user to use the socket intuitively, the method of using the socket includes the following steps. First, one of the first fitting portion 12, the second fitting portion 21, and the third fitting portion 31 is selected according to the size of the driven member to be rotated (the first driven member 91, the second driven member 92, or the third driven member 93). For example, when the first fitting portion 12 is selected, the second fitting portion 21 (the second member 2) in the initial position is pressed in a direction approaching the connecting portion 11. This causes the second fitting portion 21 to retreat inward relative to the first fitting portion 12 (to move toward the connecting portion 11). The first driven member 91 is fitted into the space vacated by the movement of the second fitting portion 21 within the first fitting portion 12, and the first driven member 91 is driven. When the second fitting portion 21 is selected, the second driven member 92 is fitted into the second fitting portion 21 to drive the second driven member. When the third fitting portion 31 is selected, the third fitting portion 31 (third member 3) in the initial position is pulled in a direction away from the connecting portion 11, causing the third fitting portion 31 to protrude from the first fitting portion 12. Then, the third driven member 93 is fitted into the third fitting portion 31 to drive the third driven member 93.

上記の使用方式の説明により、第１嵌め部１２が第２嵌め部２１及び第３嵌め部３１を離隔して、第２嵌め部２１及び第３嵌め部３１が第１部材１の軸方向に移動する際に互いに干渉しないという長所を有することが分かる。第２嵌め部２１が第１嵌め部１２から突出しないことが好ましい。この場合、動かない第１嵌め部１２により、異物による第２嵌め部２１の意図しない押し込みを防止することができる。 From the above description of the usage method, it can be seen that the first fitting portion 12 has the advantage of separating the second fitting portion 21 and the third fitting portion 31, so that the second fitting portion 21 and the third fitting portion 31 do not interfere with each other when moving in the axial direction of the first member 1. It is preferable that the second fitting portion 21 does not protrude from the first fitting portion 12. In this case, the immobile first fitting portion 12 can prevent the second fitting portion 21 from being unintentionally pushed in by a foreign object.

次に、前記ソケットの構造をより詳細に説明する。本実施形態では、第１部材１の周方向（軸周りの方向）において、第１嵌め部１２は、第２嵌め部２１および第３嵌め部３１と噛み合っている。このような構成により、図示しない駆動工具によって第１部材１（結合部１１）が回転駆動されることによって、第１嵌め部１２、第２嵌め部２１および第３嵌め部３１が一体的に回転する。第１嵌め部１２に第１多角穴８１が形成されている。第２嵌め部２１に第２多角穴８２が形成されている。第３嵌め部３１に第３多角穴８３が形成されている。第１多角穴８１、第２多角穴８２及び第３多角穴８３は、それぞれ六角穴または十二角穴である。これにより、ユーザーの各種の要求を満足することができる。本実施形態では、内から外へ、第２嵌め部２１、第１嵌め部１２及び第３嵌め部３１が採用する多角穴が、六角、六角、十二角であるが、本発明はこれらに限定されない。もちろん、内から外へ、六角、六角、六角でもよく、六角、六角、十二角でもよく、六角、十二角、六角でもよく、十二角、六角、六角でもよく、六角、十二角、十二角でもよく、十二角、六角、十二角でもよく、十二角、十二角、六角でもよく、十二角、十二角、十二角でもよい。 Next, the structure of the socket will be described in more detail. In this embodiment, the first fitting portion 12 is engaged with the second fitting portion 21 and the third fitting portion 31 in the circumferential direction (direction around the axis) of the first member 1. With this configuration, the first fitting portion 12, the second fitting portion 21, and the third fitting portion 31 rotate integrally when the first member 1 (joint portion 11) is rotated by a driving tool (not shown). A first polygonal hole 81 is formed in the first fitting portion 12. A second polygonal hole 82 is formed in the second fitting portion 21. A third polygonal hole 83 is formed in the third fitting portion 31. The first polygonal hole 81, the second polygonal hole 82, and the third polygonal hole 83 are each a hexagonal hole or a dodecagonal hole. This makes it possible to satisfy various requirements of users. In this embodiment, from the inside to the outside, the polygonal holes used by the second fitting portion 21, the first fitting portion 12, and the third fitting portion 31 are hexagonal, hexagonal, and dodecagonal, but the present invention is not limited to these. Of course, from the inside to the outside, they may be hexagonal, hexagonal, hexagonal, hexagonal, dodecagonal, hexagonal, dodecagonal, hexagonal, dodecagonal, hexagonal, dodecagonal, hexagonal, dodecagonal, dodecagonal, hexagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal, dodecagonal.

本実施形態では、第１部材１は、更に、収容空間１４と、収容空間１４を囲む第１裏壁（内壁）１６と、を備える。第２部材２は、収容空間１４に移動可能に差し込まれている。収容空間１４に、弾性部材４が設けられている。本実施形態では、弾性部材４として、コイルバネが用いられる。第１部材１の軸方向において、弾性部材４の一端が第１裏壁１６に接続され、他端が第２部材２に接続されている。これにより、第２部材２は結合部１１から離れる方向へ付勢される。第１被駆動部材９１が第１嵌め部１２から抜き出されるときには、弾性部材４により第２部材２が初期の位置に戻される。一方、第１嵌め部１２に第１被駆動部材９１を嵌めるときには、弾性部材４により、第２嵌め部２１が第１被駆動部材９１に緊密に押し付けられる。これにより、前記ソケットと第１被駆動部材９１の接触面積を増加することができ、ひいては第１被駆動部材９１を安定的に駆動することができる。特に、前記ソケットを上方に向けた状態で第１被駆動部材９１を嵌めるときに、第１被駆動部材９１を安定的に駆動することができる。 In this embodiment, the first member 1 further includes an accommodation space 14 and a first back wall (inner wall) 16 surrounding the accommodation space 14. The second member 2 is movably inserted into the accommodation space 14. An elastic member 4 is provided in the accommodation space 14. In this embodiment, a coil spring is used as the elastic member 4. In the axial direction of the first member 1, one end of the elastic member 4 is connected to the first back wall 16, and the other end is connected to the second member 2. As a result, the second member 2 is biased in a direction away from the connecting portion 11. When the first driven member 91 is extracted from the first fitting portion 12, the second member 2 is returned to its initial position by the elastic member 4. On the other hand, when the first driven member 91 is fitted into the first fitting portion 12, the second fitting portion 21 is tightly pressed against the first driven member 91 by the elastic member 4. This increases the contact area between the socket and the first driven member 91, and therefore allows the first driven member 91 to be driven stably. In particular, when the first driven member 91 is fitted with the socket facing upward, the first driven member 91 can be driven stably.

また、具体的には、第２部材２の第２外壁（外周面）２２に止め部２３が突出するように設けられている。本実施形態では、第２外壁２２の結合部１１側の端部において、外側（第１部材１の軸方向に直交する方向（径方向）における外側）に突出するように、フランジ状の止め部２３が設けられている。止め部２３と第２嵌め部２１とは、第２部材２の軸方向に距離を置いて設けられている。少なくとも一つの規制部材５は、第１部材１において位置決めされて設けられている。規制部材５は、止め部２３と第２嵌め部２１との間において第１裏壁１６から内側に突出し、第２外壁２２に対してスライドすることが可能である。第１部材１の軸方向における第２部材２の外側への移動は、止め部２３と規制部材５とが互いに干渉する（引っ掛かる）ことにより規制される。その結果、第２部材２が第１部材１から抜け落ちることを防止することができる。これにより、第２部材２は、第１部材１に対して一定の距離だけ移動することができる。本実施形態では、規制部材５および止め部２３が請求項１における「第１規制手段」に相当する。 Specifically, a stopper 23 is provided on the second outer wall (outer peripheral surface) 22 of the second member 2 so as to protrude. In this embodiment, a flange-shaped stopper 23 is provided at the end of the second outer wall 22 on the joining portion 11 side so as to protrude outward (outward in a direction (radial direction) perpendicular to the axial direction of the first member 1). The stopper 23 and the second fitting portion 21 are provided at a distance in the axial direction of the second member 2. At least one regulating member 5 is positioned and provided on the first member 1. The regulating member 5 protrudes inward from the first back wall 16 between the stopper 23 and the second fitting portion 21 and can slide relative to the second outer wall 22. The outward movement of the second member 2 in the axial direction of the first member 1 is regulated by the stopper 23 and the regulating member 5 interfering with each other (hooking on each other). As a result, it is possible to prevent the second member 2 from falling off the first member 1. This allows the second member 2 to move a certain distance relative to the first member 1. In this embodiment, the restricting member 5 and the stopper portion 23 correspond to the “first restricting means” in claim 1 .

より具体的には、第１部材１に貫通孔１３が少なくとも一つ設けられている。本実施形態では、貫通孔１３の数量は、規制部材５の数量（本実施形態では二つ）と同じである。規制部材５は、貫通孔１３に挿通され、第１裏壁１６から突出する。そして嵌めリング６は、第１部材１の外側に嵌められて位置決めされ、規制部材５を外側から内側に向かって押し付けることにより、規制部材５が第１裏壁１６から突出する状態を保持する。 More specifically, at least one through hole 13 is provided in the first member 1. In this embodiment, the number of through holes 13 is the same as the number of regulating members 5 (two in this embodiment). The regulating members 5 are inserted through the through holes 13 and protrude from the first back wall 16. The fitting ring 6 is fitted to the outside of the first member 1 to position it, and by pressing the regulating members 5 from the outside to the inside, the regulating members 5 are maintained in a state protruding from the first back wall 16.

本実施形態では、第３部材３は、第１部材１に対して移動可能であるように第１部材１の外側に嵌められる。第３嵌め部３１に第３被駆動部材９３が嵌め込まれているときには、第１嵌め部１２が第３被駆動部材９３に当接するため、支持力が安定的となる。 In this embodiment, the third member 3 is fitted to the outside of the first member 1 so as to be movable relative to the first member 1. When the third driven member 93 is fitted into the third fitting portion 31, the first fitting portion 12 abuts against the third driven member 93, so that the supporting force is stable.

詳細には、第１部材１の第１外壁（外周面）１５に環状溝１７が二つ設けられている。二つの環状溝１７は、第１部材１の長手方向（軸方向）に距離を置いて設けられる。スライド部材７は、第３部材３において位置決められ、第３部材３の第３裏壁（内壁）３２から突出する。本実施形態では、第３裏壁３２において第３嵌め部３１よりも結合部１１側に、環状溝３３が設けられ、環状溝３３にスライド部材７が嵌められている。スライド部材７は、例えばＣリングである。スライド部材７は、二つの環状溝１７の間において、第１外壁１５に対してスライドすることが可能であり、選択的に、二つの環状溝１７のうちの一つに嵌め込むことができる。これにより、第３部材３が第１部材１から抜け落ちることを防止することができ、そして第３部材３を位置決めすることもできる。二つの環状溝１７には、斜めガイド面１７１がそれぞれ設けられている。より具体的には、一方の環状溝１７において、他方の環状溝１７側の側面が斜めガイド面１７１として構成され、他方の環状溝１７において、一方の環状溝１７側の側面が斜めガイド面１７１として構成されている。一方の環状溝１７の斜めガイド面１７１は、他方の環状溝１７に近付くほど外側に位置するように、環状溝１７の底面から斜め外側に向かって広がるように延び、他方の環状溝１７の斜めガイド面１７１は、一方の環状溝１７に近付くほど外側に位置するように、環状溝１７の底面から斜め外側に向かって広がるように延びている。斜めガイド面１７１により、スライド部材７がガイドされて環状溝１７に入り、又は環状溝１７から抜け出る。本実施形態では、スライド部材７と、二つの環状溝１７のうちの結合部１１側の環状溝１７とが請求項１における「第２規制手段」に相当する。また、スライド部材７と、二つの環状溝１７のうちの第１嵌め部１２側の環状溝１７とが請求項１における「第３規制手段」に相当する。 In detail, two annular grooves 17 are provided in the first outer wall (outer peripheral surface) 15 of the first member 1. The two annular grooves 17 are provided at a distance in the longitudinal direction (axial direction) of the first member 1. The slide member 7 is positioned in the third member 3 and protrudes from the third back wall (inner wall) 32 of the third member 3. In this embodiment, an annular groove 33 is provided in the third back wall 32 on the coupling portion 11 side from the third fitting portion 31, and the slide member 7 is fitted in the annular groove 33. The slide member 7 is, for example, a C-ring. The slide member 7 can slide with respect to the first outer wall 15 between the two annular grooves 17, and can be selectively fitted into one of the two annular grooves 17. This can prevent the third member 3 from falling off the first member 1, and can also position the third member 3. The two annular grooves 17 are each provided with an inclined guide surface 171. More specifically, in one annular groove 17, a side surface on the other annular groove 17 side is configured as an oblique guide surface 171, and in the other annular groove 17, a side surface on the one annular groove 17 side is configured as an oblique guide surface 171. The oblique guide surface 171 of one annular groove 17 extends so as to widen obliquely outward from the bottom surface of the annular groove 17 so as to be positioned more outward as it approaches the other annular groove 17, and the oblique guide surface 171 of the other annular groove 17 extends so as to widen obliquely outward from the bottom surface of the annular groove 17 so as to be positioned more outward as it approaches the one annular groove 17. The oblique guide surface 171 guides the slide member 7 into the annular groove 17 or out of the annular groove 17. In this embodiment, the slide member 7 and the annular groove 17 on the coupling portion 11 side of the two annular grooves 17 correspond to the "second restricting means" in claim 1. Further, the slide member 7 and the annular groove 17 on the first fitting portion 12 side out of the two annular grooves 17 correspond to the “third restricting means” in claim 1 .

特に、第２部材２の移動は、第２外壁２２の止め部２３と、第１部材１に挿通された少なくとも一つの規制部材５とにより規制される。なお、第３部材３の移動は、第３裏壁３２に嵌められているスライド部材７と、第１外壁１５に形成された二つの環状溝１７とによりが規制される。加工するときに、加工をする作業者は、第１外壁１５及び第２外壁２２に対する加工を容易に制御することが可能であり、第３裏壁３２だけに対して切削を行うことが必要である。換言すると、本発明に係るソケットの構造によれば、作製のプロセスが簡単となり、組付け作業の工数を減少することができる。 In particular, the movement of the second member 2 is restricted by the stopper 23 of the second outer wall 22 and at least one restricting member 5 inserted into the first member 1. The movement of the third member 3 is restricted by the slide member 7 fitted into the third back wall 32 and two annular grooves 17 formed in the first outer wall 15. When machining, the operator can easily control the machining of the first outer wall 15 and the second outer wall 22, and only the third back wall 32 needs to be cut. In other words, the socket structure according to the present invention simplifies the manufacturing process and reduces the number of steps in the assembly work.

第１部材１の二つの環状溝１７が設けられている部分（二つの環状溝１７の間の部分を含む）を第２区域１９とする。第１部材１の第１区域１８は、第２区域１９及び結合部１１と連接し、第１嵌め部１２は、第２区域１９の第１区域１８とは反対側の端部と連接する。第１区域１８、第２区域１９及び第１嵌め部１２のうち、第２区域１９の厚さ（本実施形態では、平均厚さ）が最も厚く、第１嵌め部１２の厚さ（本実施形態では、平均厚さ）が最も薄い。そして第２区域１９の外径が最も大きく、貫通孔１３が第１区域１８に設けられている。本実施形態では、第１部材１の軸方向において嵌めリング６と第２区域１９とが並ぶように、かつ嵌めリング６の側面が第２区域１９に当接するように、嵌めリング６が第１区域１８に嵌められる。 The portion of the first member 1 where the two annular grooves 17 are provided (including the portion between the two annular grooves 17) is the second region 19. The first region 18 of the first member 1 is connected to the second region 19 and the connecting portion 11, and the first fitting portion 12 is connected to the end of the second region 19 opposite the first region 18. Of the first region 18, the second region 19, and the first fitting portion 12, the second region 19 has the thickest thickness (in this embodiment, the average thickness) and the first fitting portion 12 has the thinnest thickness (in this embodiment, the average thickness). The second region 19 has the largest outer diameter, and the through hole 13 is provided in the first region 18. In this embodiment, the fitting ring 6 is fitted into the first region 18 so that the fitting ring 6 and the second region 19 are aligned in the axial direction of the first member 1 and the side of the fitting ring 6 abuts against the second region 19.

本実施形態では、第１嵌め部１２、第２嵌め部２１及び第３嵌め部３１のうち、第３嵌め部３１の肉厚（本実施形態では、平均肉厚）が最も厚く、第１嵌め部１２の肉厚（本実施形態では、平均肉厚）が最も薄い。なお、ソケットの使用時に要求される強度を確保するために、第１嵌め部１２、第２嵌め部２１、および第３嵌め部３１の肉厚はそれぞれ、１.５mmより大きいことが好ましい。また、第１部材１が第３被駆動部材９３に当接することを可能にするために、第１部材１の長手方向（軸方向）における、第１嵌め部１２の長さと第３嵌め部３１の長さとの比（第１嵌め部１２の長さ／第３嵌め部３１の長さ）は、０．９～１．１であることが好ましく、第１嵌め部１２の長さが第３嵌め部３１の長さと同じであることがより好ましい。同じように、第２部材２が第１被駆動部材９１に当接することを可能にするために、第２嵌め部２１の長さと第１嵌め部１２の長さの比（第２嵌め部２１の長さ／第１嵌め部１２の長さ）は、０.５～０.７であることが好ましい。 In this embodiment, among the first fitting portion 12, the second fitting portion 21, and the third fitting portion 31, the third fitting portion 31 has the thickest wall thickness (in this embodiment, the average wall thickness), and the first fitting portion 12 has the thinnest wall thickness (in this embodiment, the average wall thickness). In order to ensure the strength required when using the socket, it is preferable that the wall thicknesses of the first fitting portion 12, the second fitting portion 21, and the third fitting portion 31 are each greater than 1.5 mm. In addition, in order to enable the first member 1 to abut against the third driven member 93, the ratio of the length of the first fitting portion 12 to the length of the third fitting portion 31 in the longitudinal direction (axial direction) of the first member 1 (length of the first fitting portion 12/length of the third fitting portion 31) is preferably 0.9 to 1.1, and it is more preferable that the length of the first fitting portion 12 is the same as the length of the third fitting portion 31. Similarly, to enable the second member 2 to abut against the first driven member 91, the ratio of the length of the second fitting portion 21 to the length of the first fitting portion 12 (length of the second fitting portion 21/length of the first fitting portion 12) is preferably 0.5 to 0.7.

本発明に係るソケットによれば、第２嵌め部を直接に使用することができ、且つ第２部材が第１部材に対して内側に後退することにより、第１嵌め部を使用することができ、第３部材が第１部材に対して外側に突出することにより、第３嵌め部を使用することができる。これにより、ユーザーは三種の異なる寸法の嵌め部を選ぶことができる。第２部材と第３部材との操作の移動方向（初期位置からの移動方向）は互いに逆であるため、構造を大幅に簡単化することができ、全体の体積を有効に減少することができ、組立作業の工数を減少することができ、収納および携帯が便利となる。 According to the socket of the present invention, the second fitting part can be used directly, and the first fitting part can be used by the second member retracting inward relative to the first member, and the third fitting part can be used by the third member protruding outward relative to the first member. This allows the user to choose fitting parts of three different sizes. Since the movement directions (movement directions from the initial position) of the second and third members are opposite to each other, the structure can be greatly simplified, the overall volume can be effectively reduced, the number of steps in the assembly work can be reduced, and storage and portability are convenient.
