Description

本発明は、概し、ソケットを駆動するために、棒杆体で成るハンドル主体にアダプター（ヘッド）を取付けた（ソケットと共にソケットレンチを構成する）ソケットレンチ用ハンドルに関するものである。   The present invention generally relates to a handle for a socket wrench in which an adapter (head) is attached to a handle main body made of a rod housing (to constitute a socket wrench together with a socket) in order to drive a socket.

両端に抜け止め用の鋼球を取付けた棒杆体でハンドル主体にアダプター（ヘッド）を、該アダプターに設けた組付け孔（貫通孔）に前記ハンドル主体を貫通させて摺嵌し、アダプターに備えた挿入体にソケットやエキステンションバーを組合わせるようにした構造のものがある（例えば、特許文献１）。   An adapter (head) is attached to the handle body with a rod housing with steel balls for retaining at both ends, and the handle body is slid through the assembly hole (through hole) provided in the adapter. There is a structure in which a socket and an extension bar are combined with the inserted body (for example, Patent Document 1).

実開平６−９８７６号公報Japanese Utility Model Publication No. 6-9876

前記従来例は、ハンドル主体を構成する棒杆体を断面円形で構成し、従って、該ハンドル主体を嵌合した、アダプター側の組付け孔の孔形も円形であるため、ソケット（ナットやボルト頭部を嵌合した）の駆動に際し、アダプター側に対してハンドル主体が、傾斜状態時など少しのことで回動してハンドル主体側から付与する駆動力がアダプターを介してソケット側に伝達されない場合がある。   In the above conventional example, the rod housing constituting the handle main body is configured with a circular cross section, and therefore the hole shape of the adapter side assembly hole into which the handle main body is fitted is also circular. When the handle main body is rotated with respect to the adapter side in a tilted state and the driving force applied from the handle main body side is not transmitted to the socket side via the adapter There is.

本発明は、このようなハンドル主体とアダプターとの嵌合関係によって生じる駆動力の低減を可及的に防いだ、アダプター付のソケットレンチ用ハンドルを提供すべく創案したものである。   The present invention was devised to provide a handle for a socket wrench with an adapter that prevents the reduction of the driving force caused by the fitting relationship between the handle main body and the adapter as much as possible.

水平方向の両端に抜け止め防止用の鋼球を取付けた棒杆体で成るハンドル主体にアダプターを、該アダプターに設けた組付け孔に前記ハンドル主体を貫通させるようにして摺嵌して成り、前記ハンドル主体の断面形と前記組付け孔の孔形を、最広径部を水平方向に沿わせて配した、互いに一致する楕円形にした構成とするのである。 An adapter is attached to a handle main body made of a rod housing having steel balls for preventing retaining at both ends in the horizontal direction , and the handle main body is slidably fitted into an assembly hole provided in the adapter, The cross-sectional shape of the handle main body and the hole shape of the assembly hole are formed into an elliptical shape that coincides with each other with the widest diameter portion arranged in the horizontal direction .

なお、ここでいう楕円形は、所謂、２支点からの距離の一定な点の軌跡を厳密に意味するものでないことは勿論である。   Of course, the oval shape here does not strictly mean the trajectory of a so-called constant point from the two fulcrums.

また、ばね付勢によって組付け孔内に突出する係止球をアダプターに収設し、該係止球が係離する受止穴をハンドル主体の長手方向の中央に設けた構成を前記手段に付加することにより、両手で操作し、駆動力をソケットに確実に付与することのできる所謂Ｔ字形ハンドルを得ることができる。   Further, the above-mentioned means has a configuration in which a locking ball protruding into the assembly hole by spring bias is accommodated in the adapter, and a receiving hole for engaging and disengaging the locking ball is provided in the center in the longitudinal direction of the handle main body. By adding, it is possible to obtain a so-called T-shaped handle that can be operated with both hands and can reliably apply a driving force to the socket.

本発明によれば、ハンドル主体を中心にしてアダプターがハンドル主体周側面に沿って回動することがないからハンドル主体からアダプターに付与する回動力が駆動力となってソケットに伝達され、駆動操作（ナットなどの締め付け操作や緩め操作など）を効率的に行えるソケットレンチ用ハンドルを提供することができる。   According to the present invention, since the adapter does not rotate around the handle main body along the peripheral surface of the handle main body, the rotational force applied to the adapter from the handle main body is transmitted to the socket as a driving force, and the drive operation It is possible to provide a socket wrench handle that can efficiently perform operations such as tightening and loosening nuts.

図面は本発明に係るソケットレンチ用ハンドルの一実施例を示し、図１は一部欠截正面図、図２はハンドル主体を断面で示した図１の側面図である。   The drawings show an embodiment of a handle for a socket wrench according to the present invention, FIG. 1 is a partially cutaway front view, and FIG. 2 is a side view of FIG.

実施例のソケットレンチ用ハンドルは、ハンドル主体１とアダプター（ヘッド）２を互いに組付けてなるもので、ハンドル主体１は断面楕円形状の、金属製の、直棒状の棒杆体で構成し、このハンドル主体１を、該ハンドル主体１の断面形と一致する孔形の組付け孔３を設けた前記アダプター２の組付け孔３に嵌挿してソケットレンチ用ハンドルＡと成し、ハンドルＡのハンドル主体１の両端の上縁には該ハンドル主体１に沿って移動させたときの、アダプター２の主体１からの抜け止めを防ぐ鋼球４を取付け（上縁に取付けることにより該鋼球４とアダプター２との位置関係を視認できる）、中央には係止球（鋼製球で成る）５が係離する受止穴６を設けてある。   The handle for the socket wrench of the embodiment is formed by assembling the handle main body 1 and the adapter (head) 2 to each other. The handle main body 1 is composed of a metal rod rod body having an elliptical cross section. The handle main body 1 is inserted into the assembly hole 3 of the adapter 2 provided with the hole-shaped assembly hole 3 that matches the cross-sectional shape of the handle main body 1 to form a socket wrench handle A. A steel ball 4 is attached to the upper edges of both ends of the main body 1 to prevent the adapter 2 from coming off from the main body 1 when moved along the handle main body 1. In the center, a receiving hole 6 for engaging and disengaging a locking ball (made of a steel ball) 5 is provided.

係止球５は、アダプター２の前記組付け孔３の内周面に設けた収納穴７にコイルばね８を介して収容したもので、コイルばね８によって組付孔３の内周面より（すなわち、組付孔３内に）突出する方向に付勢され、組付け孔３を通して嵌合したハンドル主体１の周側に常時圧接するようにアダプター２内に収設したものである。   The locking ball 5 is housed in a housing hole 7 provided on the inner peripheral surface of the assembly hole 3 of the adapter 2 via a coil spring 8. That is, it is urged in a protruding direction (into the assembly hole 3) and is accommodated in the adapter 2 so as to be always in pressure contact with the peripheral side of the handle main body 1 fitted through the assembly hole 3.

なお、アダプター２は、ソケット９に嵌合組付ける挿入体１０を備え、該挿入体１０にはばねによって突出方向に付勢させた係止球１１を備え、この係止球１１が前記ソケット９（或いはエキステンションバー）に備えた角穴１２の壁面に圧接してアダプター２とソケット９との組付けが確実に行われる。   The adapter 2 includes an insertion body 10 fitted and assembled to the socket 9, and the insertion body 10 includes a locking ball 11 biased in a protruding direction by a spring, and the locking ball 11 is connected to the socket 9. The adapter 2 and the socket 9 are securely assembled by pressing against the wall surface of the square hole 12 provided in the (or extension bar).

しかして、ナットなどを緊締したり、緩めたりする時に、殊に強いトルクを必要とするとき、アダプター２をハンドル主体１の一端側に移動させて当該ナットなどにアダプター２を組合わせ、ハンドル主体１によるアダプター２に対する駆動力を付与すると、強いトルクを得られてナットなどの緊締或いは緩め操作を行うことができる。   Therefore, when tightening or loosening a nut, etc., especially when a strong torque is required, the adapter 2 is moved to one end side of the handle main body 1 and the adapter 2 is combined with the nut etc. When a driving force is applied to the adapter 2 by 1, a strong torque can be obtained and a tightening or loosening operation of a nut or the like can be performed.

そして、これらの作業中、ハンドル主体１を中心とするアダプター２の回動が生じることがないので該作業を円滑に行うことができるのである。   During these operations, the adapter 2 does not rotate around the handle main body 1, so that the operation can be performed smoothly.

なお、アダプター２をハンドル主体１の中央位置に配すると、アダプター２に収設した係止球５がハンドル主体１側の受止穴６に係止していわばＴ字形ハンドルとなってナット等の駆動作業を行うことができ、このときアダプター２にエキステンションバーを接続することによってＴ字形ハンドル状態に尚一層近似させることができる。   When the adapter 2 is arranged at the center position of the handle main body 1, if the locking ball 5 accommodated in the adapter 2 is locked in the receiving hole 6 on the handle main body 1 side, it becomes a T-shaped handle, such as a nut. A driving operation can be performed, and at this time, an extension bar can be connected to the adapter 2 to further approximate the T-shaped handle state.

実施例のハンドル主体１は、該ハンドル主体１の断面楕円形の最広径部（長軸）を水平方向に沿わせて配してあるが（図１の２点鎖線や図２の断面形で明らか）、これは、アダプター２側に配した係止球５が係止（合）する受止穴６を棒杆状の該ハンドル主体１の周側面（下端部）に不都合なく形成するため（係止球５をコイルばね８と共に収容する収納穴７を形成する主体１の周側面が平面に近いほど形成し易く、つまり、急な円曲面より緩やかな円曲面の方が形成し易く、収納穴７の開口縁を比較的下方に位置させることができる）と、トルク（駆動力）を付与しても、少くとも短軸側より折り曲がりにくく耐久性を期待できるためである。   The handle main body 1 of the embodiment has the widest diameter portion (long axis) of the elliptical cross section of the handle main body 1 arranged along the horizontal direction (the two-dot chain line in FIG. 1 or the cross-sectional shape in FIG. 2). This is because the receiving hole 6 in which the locking ball 5 arranged on the adapter 2 side is locked (coincided) is formed on the peripheral side surface (lower end portion) of the rod-shaped handle main body 1 without any inconvenience. (It is easier to form the peripheral side surface of the main body 1 that forms the storage hole 7 that accommodates the locking ball 5 together with the coil spring 8 is closer to a flat surface, that is, a gentle circular curved surface is easier to form than a sharp circular curved surface, This is because the opening edge of the storage hole 7 can be positioned relatively downward) and even when torque (driving force) is applied, it is difficult to bend at least from the short shaft side and durability can be expected.
