Description
【０００１】[0001]
本考案は、物品の組み立てあるいは連結等に使用する包被ナットによる締結体 に関する。 The present invention relates to a fastening body with a covering nut used for assembling or connecting articles.
【０００２】[0002]
物品等の取付部材を多数のボルト・ナットを用いて緊締する際には、それぞれ のナットまたはボルトが、所定の締付力により締め付けられているか（締め忘れ がないか）、また、締め付けられた後のナットまたはボルトは、緩みを生じない か、等が重要な事柄となる。 When tightening a large number of bolts and nuts on a mounting member such as an article, make sure that each nut or bolt is tightened with the specified tightening force (whether you forget to tighten it), or that it was tightened. For the subsequent nuts or bolts, it is important that they do not come loose.
【０００３】 そのため、前記した締め忘れについては、本考案者は、ボルトまたはナットに 合成樹脂フィルムを包被させて、この合成樹脂フィルムの有無により、緊締済み と未緊締とが判別できる技術を提供した。（例えば、実開昭６２−１９０１１４ 号公報，実開昭６３−７２３１２号公報参照） また、前記したボルトまたはナットの緩み止めの対策については、その座面に スプリングワッシャ等を介在させたり、ナットおよびボルトに割りピンを係合さ せたり、更には、ナットの上面においてボルトのねじ部へダブルナットやばねナ ットを取り付けたり等を行なっていた。Therefore, in the case of forgetting the tightening described above, the present inventor provides a technique in which a bolt or a nut is covered with a synthetic resin film and it is possible to determine whether the tightening is completed or not tightened by the presence or absence of the synthetic resin film. did. (For example, see Japanese Utility Model Laid-Open No. 62-190114 and Japanese Utility Model Laid-Open No. 63-72312) As for the above-mentioned measures to prevent the bolts or nuts from loosening, a spring washer or the like is interposed on the seat surface, or a nut is used. In addition, the cotter pin was engaged with the bolt, and further, a double nut or a spring nut was attached to the threaded portion of the bolt on the upper surface of the nut.
【０００４】 しかしながら、前者の対応策は、フィルムの離脱により締め忘れを確認してい たものであるから、ボルト・ナットから外されたフィルムは、取付部材の付近に 散乱してゴミになり、その後始末が大変となるばかりか、取付部材が機械系の場 合は、その作動部へボルト・ナットから外れたフィルムが混入して、該取付部材 の操作に支障を来す。However, since the former countermeasure is to confirm that the film has been forgotten to be tightened due to the removal of the film, the film removed from the bolts and nuts is scattered near the mounting member and becomes dust, and Not only is it troublesome to clean up, but when the mounting member is a mechanical system, the film that comes off the bolts and nuts mixes into its operating part, which hinders the operation of the mounting member.
【０００５】 あるいは、外れたフィルムが締め付け工具であるボックスレンチ内に詰まって 他のナットの締め付けに際して不都合を来す。Alternatively, the detached film becomes stuck in a box wrench which is a tightening tool, which causes a problem when tightening other nuts.
【０００６】 更に、後者の対応策において、スプリングワッシャを用いた場合でも振動等を 発生する箇所に使用したときは、未だ緩みを生ずることがあり、割りピンやダブ ルナット，ばねナットを用いた場合は、締結工程が増加して多数のボルト・ナッ トによる緊締の場合は作業性が著しく低下する。 等の様々な問題点を有するものであった。Further, in the latter measure, even when a spring washer is used, when it is used in a place where vibration is generated, it may still loosen, and when a cotter pin, double nut, or spring nut is used. In the case of tightening with a large number of bolts and nuts, the workability is significantly reduced. There were various problems such as.
【０００７】[0007]
本考案は、前記した問題点を解決するためになされたもので、取付部材に挿嵌 したおねじ体に、ナットの外周へ装着した外被部材を収縮させて密着させ、該外 被部材の一側部を前記ナットのめねじ谷径より小径に成形することで、おねじ体 のおねじに螺合・密着して一体的となる係止部を形成させた包被ナットを螺合さ せることにより、ナットの戻り止めや締め忘れあるいはナットに装着した外被部 材の飛散を防止することができる包被ナットによる締結体を提供することを目的 としている。 The present invention has been made to solve the above-mentioned problems, and an external thread member mounted on the outer circumference of a nut is contracted and closely adhered to an externally threaded body inserted in a mounting member, and the external thread member of the external thread member is attached. By forming one side with a diameter smaller than the root diameter of the female thread of the nut, a covered nut with a locking part that is screwed and closely attached to the male thread of the male thread body is formed. The purpose of the present invention is to provide a fastening body with a covered nut that can prevent the detent of the nut, forgetting to tighten it, or scattering the outer covering material attached to the nut.
【０００８】[0008]
前記した目的を達成するための本考案の手段は、 取付部材を挟んでおねじ体とナットとにより該取付部材を締結する締結体にお いて、 取付部材に挿嵌するおねじ体と、該おねじ体のおねじに螺合して、ナットの外 周へ筒状に成形した収縮性外被部材を装着し、該外被部材を収縮させてナット外 周へ密着させると共に、この外被部材の一側部を前記ナットのめねじにおける谷 径より小径に成形し、おねじ体のおねじとに一体的となる係止部を形成させた包 被ナットと、 を備えさせた包被ナットによる締結体の構成にある。 The means of the present invention for achieving the above-mentioned object is a fastening body that fastens the mounting member with a male screw body and a nut sandwiching the mounting member. A shrinkable jacket member that is formed into a tubular shape is attached to the outer circumference of the nut by screwing it onto the male thread of the male threaded body, and the outer jacket member is shrunk so that it closely adheres to the outer circumference of the nut. An encapsulation nut, in which one side portion of the member is formed to have a diameter smaller than the root diameter of the female thread of the nut, and an engaging portion formed integrally with the male thread of the male thread body is formed. It is in the structure of the fastening body by the nut.
【０００９】 また、 前記係止部は、 円筒状でその断面形状を真円状、または、異形円状あるいは偏心状に形成させ る。Further, the locking portion is cylindrical and its cross-sectional shape is formed into a perfect circular shape, a modified circular shape or an eccentric shape.
【００１０】[0010]
前記のように構成される本考案は以下に述べる作用を奏する。 The present invention configured as described above has the following operations.
【００１１】 ナットの外周へ筒状の収縮性外被部材を装着した後、この外被部材を収縮させ ると、該外被部材はナット外周に密着される。After the tubular shrinkable jacket member is attached to the outer circumference of the nut and then the jacket member is contracted, the jacket member is brought into close contact with the outer circumference of the nut.
【００１２】 また、この外被部材の一側部はナットのめねじにおける谷径より小径に成形さ れて、おねじ体のおねじへの係止部が形成された包被ナットが得られる。Further, one side portion of the outer cover member is formed to have a diameter smaller than the root diameter of the female thread of the nut, so that a covered nut in which a locking portion for the male thread of the male screw body is formed can be obtained. .
【００１３】 物品等の取付部材の締結にあっては、この取付部材を挟んで包被ナットとおね じ体とを、この包被ナットにおける係止部の他側から螺合して、包被ナットまた はおねじ体を工具により回転すると、その螺合に伴っておねじ体のおねじにおけ る先端部はナットの一側に達するもので、更に回転させると、該おねじはナット の一側部より突出して、包被ナットの係止部に螺合するので、この係止部がおね じに結合されて一体化される。In fastening an attachment member for an article or the like, the covering nut and the mandrel are screwed from the other side of the engaging portion of the covering nut with the attaching member sandwiched therebetween, and the covering member is covered. When the nut or male screw body is rotated by a tool, the tip of the male screw of the screw body reaches one side of the nut due to the screwing. Since it protrudes from the side portion and is screwed into the locking portion of the covering nut, the locking portion is connected to the male and integrated.
【００１４】 したがって、取付部材への緊締後は、この係止部がおねじ体のおねじに螺合さ れて、ナットの緩み方向への回転を、その摩擦やおねじ，めねじへの噛み込みに より抑止するので戻り止めとなる。Therefore, after tightening to the mounting member, this locking portion is screwed onto the male screw of the male screw body to prevent the nut from rotating in the loosening direction due to its friction and to the male screw and the female screw. Since it is restrained by biting, it becomes a detent.
【００１５】 ナットの外周に密着した外被部材は、工具による緊締時に剥がれても、これと 接続する係止部により飛散しない。The outer cover member that is in close contact with the outer periphery of the nut does not scatter even if it is peeled off when tightened by a tool due to the engaging portion connected to the outer cover member.
【００１６】[0016]
次に、本考案に関する包被ナットによる締結体の一実施例を図面に基づいて説 明する。 Next, an embodiment of a fastening body with a covering nut according to the present invention will be described with reference to the drawings.
【００１７】 図１〜図１０においてＡは包被ナットで、取付部材等の物品ｂの組み立て、あ るいは連結等に利用されるものであって、ナット１と、収縮性外被部材２とによ り基本的になり、この包被ナットＡとおねじ体４とにより取付部材等の物品ｂを 緊締する締結体が構成される。In FIG. 1 to FIG. 10, reference numeral A denotes a cover nut, which is used for assembling or connecting articles b such as a mounting member, and includes a nut 1 and a shrinkable jacket member 2. By this cover nut A and the male screw body 4, a fastening body for tightening the article b such as a mounting member is constituted.
【００１８】 そして、この包被ナットＡは、ナット１の外周へ筒状に成形した収縮性外被部 材２を装着し、該外被部材２を加熱等により収縮させて、ナット１の外周へ密着 させると共に、この外被部材２の一側部を、ナット１のめねじ３における谷径よ り、図１（ａ）および図２において符号ｘにより示すように、小径に成形するこ とで、ボルト等のおねじ体４におけるおねじ５への係止部６が形成される。In this encapsulation nut A, a shrinkable outer covering member 2 formed in a tubular shape is attached to the outer circumference of the nut 1, and the outer covering member 2 is shrunk by heating or the like, so that the outer circumference of the nut 1 is reduced. In addition, the outer cover member 2 is formed so that one side portion of the outer cover member 2 has a smaller diameter than the root diameter of the female screw 3 of the nut 1 as indicated by a symbol x in FIGS. 1 (a) and 2. Thus, the locking portion 6 for the male screw 5 in the male screw body 4 such as a bolt is formed.
【００１９】 前記したナット１は、前記したように、取付部材等の物品ｂの組み立て、ある いは連結等に利用される慣用のものが用いられるもので、その種類やねじの形式 ，材質等は限定されるものではない。As described above, the nut 1 is a conventional one used for assembling or connecting the article b such as a mounting member, and the type, type of screw, material, etc. Is not limited.
【００２０】 また、前記した収縮性外被部材２は、円筒状で円周方向への収縮率の大きい熱 収縮性を有する合成樹脂材等により所定厚さの薄厚に形成されるもので、フィル ム状のものが適しており、必要に応じて、図１（ｂ）および図２（ｆ）に示すよ うに、軸方向や、軸方向および円周方向にミシン目７を施してナット１に密着し た部分を割れやすくすることもある。The shrinkable outer cover member 2 is made of a synthetic resin material or the like having a cylindrical shape and a large shrinkage ratio in the circumferential direction and having a heat shrinkability so as to have a predetermined thin thickness. It is suitable that the nut 1 is provided with a perforation 7 in the axial direction or in the axial direction and the circumferential direction as shown in FIGS. 1 (b) and 2 (f), if necessary. In some cases, the close contact part may be easily cracked.
【００２１】 なお、この外被部材２は、ゴム系樹脂の薄膜材により形成して、ナット１およ びおねじ体４のおねじ５に対して弾力的に当接させることもある。The outer cover member 2 may be formed of a thin film material of rubber-based resin, and may be elastically brought into contact with the nut 1 and the male screw 5 of the male screw body 4.
【００２２】 ナット１への外被部材２への密着にあっては、図示してないが、ナット１の外 周に溝やローレット等の係合加工を施して、この部分へ収縮させた外被部材２が 絡み付くように形成することもある。Although not shown in the drawing, the nut 1 is in close contact with the jacket member 2. The nut 1 is provided with engagement processing such as grooves or knurls on the outer periphery thereof, and the nut 1 is contracted to the outer surface. The member 2 may be formed so as to be entangled.
【００２３】 そして、この係止部６の形成にあっては、図１（ａ）に示すように、ナット１ における一側部のねじ孔の一部を覆うように成形したり、図２（ａ），（ｃ）〜 （ｄ）に示すように、ナット１の一側部より軸方向へ所定寸法に突出する筒状部 に成形する。In forming the engaging portion 6, as shown in FIG. 1A, the nut 1 is formed so as to cover a part of the screw hole on one side, or as shown in FIG. As shown in a) and (c) to (d), the nut 1 is formed into a cylindrical portion that protrudes from one side portion of the nut 1 in the axial direction to a predetermined size.
【００２４】 更には、図２（ｂ）に示すように、ナット１における一側部においてねじ孔に 所定寸法が入り込むようにするもので、めねじ３面へ密着するか、あるいは、め ねじ３面とは離隔するように成形される。Further, as shown in FIG. 2 (b), a predetermined size is inserted into the screw hole at one side portion of the nut 1, and the nut 1 is brought into close contact with the surface of the female screw 3 or the female screw 3 It is formed so as to be separated from the surface.
【００２５】 また、この係止部６は、軸方向に円筒状に形成すると共に、その断面形状を、 図３（ａ）に示すように、ナット１のねじ孔と真円状に形成したり、異形円状す なわち、図３（ｂ）に示すように、楕円状に、図３（ｃ）に示すように、連続し たまたは不連続の波形状（凹凸状）に形成したり、更には、図３（ｄ）および図 ２（ｄ）に示すように、ナット１のねじ孔に対して偏心状に形成させたりするも ので、円周方向の内外に対して起こる歪み状に湾曲させる場合もある。Further, the locking portion 6 is formed in a cylindrical shape in the axial direction, and its cross-sectional shape is formed in a circular shape with the screw hole of the nut 1 as shown in FIG. 3 (a). , An irregular circular shape, that is, an elliptical shape as shown in FIG. 3 (b), or a continuous or discontinuous wave shape (uneven shape) as shown in FIG. 3 (c), Further, as shown in FIGS. 3 (d) and 2 (d), the nut 1 may be formed eccentrically with respect to the screw hole, so that the nut 1 may be curved in a distortion that occurs inside and outside in the circumferential direction. In some cases,
【００２６】 更に、図２（ｃ）に示すように、筒状に形成した係止部６を、その一方または 両方を軸方向に対して所定の傾斜状に形成することもあるもので、図示してない が、この係止部６は、ナット１の側面側から先端へ向かって徐々に小径となる先 つぼみ状に成形させることもあるものであって、何れも、ナット１のめねじ３に おける谷径より、図１（ａ）および図２において符号ｘにより示すように、小径 に成形するものであって、図２（ｅ）に示すように、比較的大幅に小径とするこ ともあるものであり、この係止部６とおねじ体４のおねじ５との螺合状態の軟硬 度合いに応じてを適宜設定する。Further, as shown in FIG. 2 (c), one or both of the tubular locking portions 6 may be formed with a predetermined inclination with respect to the axial direction. Although not shown, the locking portion 6 may be formed in a bud shape in which the diameter gradually decreases from the side surface side of the nut 1 toward the tip. 1 (a) and 2 shows a smaller diameter than the root diameter in FIG. 1, and the diameter can be relatively small as shown in FIG. 2 (e). However, the value is appropriately set according to the degree of softness of the engagement between the locking portion 6 and the male screw 5 of the male screw body 4.
【００２７】 なお、この係止部６は、その開口端側を、図２（ａ）において仮想線で示すよ うに、閉塞した構成であってもよく、この場合は、取付部材ｂへの締結後にあっ て、おねじ５とめねじ３間の間隙が覆われるため、締結部の気密や油・水密が保 てると共に、コンクリート等の打設箇所にあっては、ナット１より突出したおね じ体４のおねじ５へのコンクリートの付着が防止できる。The locking portion 6 may have a configuration in which the opening end side thereof is closed as shown by an imaginary line in FIG. 2A, and in this case, fastening to the mounting member b is performed. Since the gap between the male screw 5 and the female screw 3 is covered later, the airtightness and oil / watertightness of the fastening part can be maintained, and the screw protruding from the nut 1 at the place where concrete, etc. is placed. Adhesion of concrete to the male screw 5 of the body 4 can be prevented.
【００２８】 したがって、前記した実施例によれば、図１（ｃ）に示すような、二部材の取 付部材ｂ，ｂを、ボルト等のおねじ体４とナット１とにより締結する場合は、ま ず、図１および図２に示すような、六角ナット１の外周へ、図１（ａ）に示すよ うに、筒状に形成した収縮性外被部材２を仮想線で示すように装着した後、この 外被部材２を加熱により収縮させると、該外被部材２は、同図において実線で示 すようにナット１の外周に密着される。Therefore, according to the embodiment described above, when the two-member mounting members b, b as shown in FIG. 1C are fastened by the male screw body 4 such as a bolt and the nut 1, First, as shown in FIGS. 1 and 2, the contractible jacket member 2 formed in a tubular shape is attached to the outer periphery of the hexagon nut 1 as shown in phantom lines as shown in FIG. 1 (a). After that, when the jacket member 2 is shrunk by heating, the jacket member 2 is brought into close contact with the outer periphery of the nut 1 as shown by the solid line in the figure.
【００２９】 そして、この外被部材１の一側部は、熱収縮によりナット１のめねじ３におけ る谷径より小径に成形されて、おねじ体４のおねじ５への係止部６が形成され、 また、該外被部材１の他側部は、図１に示すように、ナット１の座面の一部に係 合するように折曲されてこの座面外縁に支持される。Then, one side portion of the outer cover member 1 is formed to have a diameter smaller than the root diameter of the female screw 3 of the nut 1 by heat shrinkage, and a locking portion to the male screw 5 of the male screw body 4. 6, the other side portion of the jacket member 1 is bent so as to engage with a part of the seat surface of the nut 1 and is supported by the outer edge of the seat surface, as shown in FIG. It
【００３０】 なお、この外被部材１の他側部は、図２（ｃ）に示すように、ナット１の該周 面に位置するように成形することもある。The other side portion of the jacket member 1 may be formed so as to be located on the peripheral surface of the nut 1 as shown in FIG. 2 (c).
【００３１】 これにより、取付部材ｂ，ｂを挟んでその両側から包被ナットＡとおねじ体４ とにより締結するもので、まず、取付部材ｂ，ｂの通孔７，７へおねじ体４のお ねじ５を通し、一方の取付部材ｂから突出したおねじ５へ、包被ナットＡの座面 側を取付部材ｂに対応させてそのめねじ３を螺合させる。As a result, the mounting members b, b are sandwiched and fastened from both sides by the covering nut A and the male screw body 4, and first, the male screw body 4 is inserted into the through holes 7, 7 of the mounting members b, b. The male screw 3 is passed through the male screw 5 and the female screw 3 protruding from the one mounting member b is engaged with the female screw 3 with the bearing surface side of the covering nut A corresponding to the mounting member b.
【００３２】 そして、包被ナットＡをスパナやレンチ等の工具を掛けて回転すると、おねじ ５とめねじ３との螺合に伴って、おねじ体４のおねじ５における先端部は、ナッ ト１の一側部、すなわち、係止部６に達するもので、更に包被ナットＡを回転さ せると、該おねじ５は、ナットＡの一側部より突出して、図１（ａ）に示すよう に、包被ナットＡの係止部６に螺合するので、この係止部６がおねじ５のねじの 山谷に係合して結合されおねじ体と一体化される。Then, when the covering nut A is rotated by applying a tool such as a wrench or a wrench, the tip portion of the male screw 5 of the male screw body 4 is screwed with the screwing of the male screw 5 and the female screw 3. When the covering nut A is further rotated, the male screw 5 protrudes from one side portion of the nut A, as shown in FIG. As shown in FIG. 5, since it is screwed into the locking portion 6 of the covering nut A, the locking portion 6 engages with the ridges and valleys of the screw of the male screw 5 and is coupled to be integrated with the male screw body.
【００３３】 なお、図２（ａ）に示すような、筒状に形成した係止部６の場合も同様に、図 ４に示すように、おねじ体４のおねじ５における山谷部に係合した螺合状態とな るもので、この係止部６は、おねじ５によりめねじ６ａが形成された状態となっ て、ナット１とのダブルナット状となる。In the case of the tubular locking portion 6 as shown in FIG. 2A, similarly, as shown in FIG. The locking portion 6 is in a double nut shape with the nut 1 in a state in which the female thread 6 a is formed by the male thread 5.
【００３４】 したがって、取付部材ｂ，ｂへの緊締後は、この係止部６がおねじ体４のおね じ５に螺合されて、ナット１の緩み方向へ回転しようとすると、その摩擦やおね じ５，めねじ３への噛み込みにより、ナット１の座面反対側においてナット１の めねじ３に噛み込まれ、ナット１の逆回転を抑止するので、該ナット１の戻り止 めとなる。Therefore, after tightening to the mounting members b, b, when the locking portion 6 is screwed into the male thread 5 of the male screw body 4 and tries to rotate in the loosening direction of the nut 1, the friction is generated. When the nut 1 and the female screw 3 are bitten, the nut 1 is bitten by the female screw 3 on the opposite side of the bearing surface of the nut 1 to prevent the nut 1 from rotating in the reverse direction. It will be
【００３５】 また、ナット１の外周面に密着した外被部材２は、工具による緊締時に掛かる 力や抵抗により、図１（ｃ）に示すように、ナット１から剥がれても、この外被 部材２の剥がれ部と接続する係止部６がおねじ体４のおねじ５に固定されている ため、おねじ４あるいはナット１より離脱して外部へ飛散しない。The outer cover member 2 that is in close contact with the outer peripheral surface of the nut 1 is peeled off from the nut 1 as shown in FIG. Since the locking portion 6 connected to the peeling portion 2 is fixed to the male screw 5 of the male screw body 4, it does not separate from the male screw 4 or the nut 1 and is not scattered to the outside.
【００３６】 特にこの包被ナットＡにあっては、ナット１の締め付け位置が係止部６によっ て目視により確認できるもので、図１（ｃ）において符号ｙにより示すように、 あらかじめ、締め込み量を決めておけば、この位置に達したナット１は、締め込 みが完了したものとの判断が外部より行なえると共に、万が一、ナット１に緩み を生じた際は、前記符号ｙの寸法変化がおねじ５において現れるので、ナット１ の戻り状態も外部より判断ができる。In particular, in the case of the envelope nut A, the tightening position of the nut 1 can be visually confirmed by the locking portion 6, and as shown by the reference sign y in FIG. If the amount of insertion is determined, it can be judged from the outside that the nut 1 that has reached this position has been tightened, and if the nut 1 becomes loose, it will be indicated by the above-mentioned symbol y. Since the dimensional change appears in the male screw 5, the returning state of the nut 1 can also be determined from the outside.
【００３７】 なお、この外被部材２は、ゴム系樹脂の薄膜材により形成して、ナット１およ びおねじ体４のおねじ５に対して弾力的に当接させるようにすれば、ナット１の おねじ体４への螺合に際して、係止部６がその弾性によって、おねじ５により押 し広げられ、螺合進行されると共に、該係止部６がおねじ５の山谷部へ一層緊密 に接触して、両者５，６に大きな摩擦抵抗を発生させることができる。If the outer cover member 2 is formed of a rubber resin thin film material and is elastically brought into contact with the nut 1 and the male screw 5 of the male screw body 4, When the nut 1 is screwed into the male screw body 4, the locking portion 6 is pushed out by the male screw 5 due to its elasticity and spreads, and the screwing progresses. It is possible to generate a large frictional resistance between both members 5 and 6 by contacting them more closely.
【００３８】 次に、図２（ｂ）に示すように、包被ナットＡにおける係止部６が、ナット１ のねじ孔内に押し込まれた状態のものは、包被ナットＡにおけるめねじ３へおね じ体４のおねじ５を螺合させると、図５（ａ）に示すように、そのおねじ５の先 端部が係止部６を押して徐々に外方へ送り出す。Next, as shown in FIG. 2B, the engagement nut 6 of the covering nut A is pushed into the screw hole of the nut 1 so that the female screw 3 of the covering nut A is When the male screw 5 of the male screw body 4 is screwed, the leading end of the male screw 5 pushes the locking portion 6 and gradually feeds it outward, as shown in FIG. 5 (a).
【００３９】 そして、更にナットＡまたはおねじ体４を回転させると、係止部６は、ついに はナット１の外方へ突出するもので、このまま回転を続けると、該係止部６はお ねじ５に馴染みつつ、図５（ｂ）に示すように、このおねじによりめねじ６ａが 形成された状態となって、ナット１とのダブルナット状となる。Then, when the nut A or the male screw body 4 is further rotated, the locking portion 6 finally projects to the outside of the nut 1. If the rotation is continued as it is, the locking portion 6 will be screwed. As shown in FIG. 5 (b), the male screw 6 a is formed by this male screw while becoming familiar with No. 5, and becomes a double nut shape with the nut 1.
【００４０】 この包被ナットＡにおける取付部材ｂの締結にあっては、前記した例と同様の 作用効果を発揮する。In fastening the mounting member b in the covering nut A, the same working effect as that of the above-described example is exhibited.
【００４１】 次に、図２（ｂ）に示すように、包被ナットＡにおける係止部６が、ナット１ のねじ孔内に押し込まれた状態で、かつ、このめねじ３に係止部６が密着した状 態のものは、包被ナットＡにおけめねじ３へおねじ体４のおねじ５を螺合させる と、図６（ａ）に示すように、そのおねじ５の先端部は係止部６に螺合する。Next, as shown in FIG. 2B, the engaging portion 6 of the covering nut A is pushed into the screw hole of the nut 1 and is engaged with the female screw 3. In the state where 6 is in close contact, when the male thread 5 of the male thread body 4 is screwed into the cover nut A, the tip of the male thread 5 is screwed as shown in FIG. 6 (a). The part is screwed onto the locking part 6.
【００４２】 そして、更にナットＡまたはおねじ体４を回転させると、係止部６は、おねじ ５とめねじ３との間に挟まった状態となるもので、図６（ｂ）に示すように、こ のおねじ５とめねじ３との隙間がなくなり緊締状態となったいわゆるカシメがな される。Then, when the nut A or the male screw body 4 is further rotated, the locking portion 6 is sandwiched between the male screw 5 and the female screw 3, as shown in FIG. 6B. Then, there is no gap between the screw 5 and the female screw 3, and the so-called caulking is performed in the tightened state.
【００４３】 この包被ナットＡにおける取付部材ｂの締結にあっても、前記した各例と同様 の作用効果を発揮するものであつて、本実施例で例示した各例の包被ナットＡに おける係止部６の構成も、前記同様の作用効果を奏するもので、その詳細な説明 は省略する。Even when the mounting member b is fastened to the covering nut A, the same effects as those of the above-described examples are exhibited, and the covering nut A of each example illustrated in the present embodiment has the following effects. The configuration of the locking portion 6 in the above also has the same effect as the above, and the detailed description thereof will be omitted.
【００４４】 また、本考案実施例における包被ナットＡは、図２（ｂ）に示すように、ナッ ト１の座面側に、スプリングワッシャー８（各種のばねであってもかまわない。 ）を添えて収縮性外被部材２により包被したり、図２（ｆ）に示すように、ナッ ト１の座面側に、スプリングワッシャー８と平座金９とを添えて収縮性外被部材 ２により包被することもあるもので、図示してないが、他の種類による座金やパ ッキン，Ｏリング等の締結や締め合わせ，戻り止め等に要する部材を包被するこ ともできる。The cover nut A in the embodiment of the present invention is, as shown in FIG. 2B, on the seat surface side of the nut 1, a spring washer 8 (various kinds of springs may be used). 2 to cover the shrinkable outer cover member 2 or, as shown in FIG. 2 (f), attach the spring washer 8 and the flat washer 9 to the seat surface side of the nut 1 to cover the contractible outer cover member 2. Although not shown in the drawing, it may also be covered by the second member, but it is also possible to cover other members such as washers, packings, O-rings, etc. necessary for fastening, tightening, and detenting.
【００４５】 また、外被部材２によるナット１の包被にあっては、図７に示すように、ナッ ト１座面の他側に、座金やパッキン，Ｏリング等の締結や締め合わせ，戻り止め 等に要する止め部材１０を添えて、前記したナット１と共に包被することもでき る。In the case of covering the nut 1 with the jacket member 2, as shown in FIG. 7, fastening or tightening of washers, packings, O-rings, etc. on the other side of the nut 1 seating surface, It is also possible to attach a stop member 10 required for detent and the like and enclose it together with the nut 1 described above.
【００４６】 図８においては、包被ナットＡの他の例による締結体を示すもので、この包被 ナットＡは、ナット１の外周へ円筒状に成形した収縮性の外被部材２を、図８（ ａ）に示すように、装着し、該外被部材２を収縮させてナット１外周へ密着させ る。FIG. 8 shows a fastening body according to another example of the covering nut A. The covering nut A has a contractible jacket member 2 formed in a cylindrical shape on the outer periphery of the nut 1. As shown in FIG. 8 (a), it is mounted, and the outer cover member 2 is contracted to be in close contact with the outer periphery of the nut 1.
【００４７】 このとき、外被部材２の係止部６は、一側部においてナット１のめねじ３にお ける谷径より略同形または大径に成形してある。At this time, the locking portion 6 of the outer cover member 2 is formed in one side portion to have substantially the same shape or a larger diameter than the root diameter of the female screw 3 of the nut 1.
【００４８】 そして、図８（ｂ）に示すように、包被ナットＡとおねじ体４との螺合による 締結後、または、その締結前に、係止部６を更に加熱等により収縮させ、ナット １の一側部より突出したおねじ体４のおねじ５における山谷部へ密着させて、こ の係止部６をおねじ５に対して一体化させることで、前記した作用・効果を発揮 させる。Then, as shown in FIG. 8B, after the fastening nut A and the male screw body 4 are fastened by screwing, or before the fastening, the locking portion 6 is further contracted by heating or the like, By bringing the locking portion 6 into integral contact with the male thread 5 of the male thread body 4 protruding from one side of the nut 1 and making the locking portion 6 integral with the male thread 5, the above-described action and effect can be obtained. Make it work.
【００４９】 なお、その際に、図９に示すように、おねじ体４のおねじ５に凹部や異なるね じピッチ等の係合部１１を設けておけば、係止部６とおねじ５との結合が一層強 固となる。At this time, as shown in FIG. 9, if the male thread 5 of the male thread body 4 is provided with a recessed portion or an engaging portion 11 such as a different thread pitch, the locking portion 6 and the male thread 5 are connected. The bond with and becomes stronger.
【００５０】 なお、ナット１を外被部材２により包被する場合、図１０に示すように、ダブ ルナット状態に設けた二つあるいは複数のナット１，１を外装することもできる もので、この組み合わせ等は任意に行なえる。When the nut 1 is covered with the jacket member 2, as shown in FIG. 10, two or a plurality of nuts 1 and 1 provided in a double nut state can be externally mounted. The combination etc. can be performed arbitrarily.
【００５１】 図１１においては、外被部材２をおねじ体４の頭部１２へ包被させた例を示す もので、同図（ａ）に示す場合は、頭部１１に穿設した凹溝１２内に外被部材２ の係止部６を、加熱等により収縮させて係合させ、該頭部１１と一体的にするこ とで、同図において仮想線で示すように、該頭部１１に係合していた外被部材２ が工具等による締結作業により外れても、この外被部材２全体は凹溝１２に係止 されて係合状態を維持し、落下や飛散することがない。FIG. 11 shows an example in which the outer cover member 2 is covered by the head 12 of the male screw body 4. In the case shown in FIG. By engaging the locking portion 6 of the outer cover member 2 in the groove 12 by shrinking it by heating or the like and engaging it with the head portion 11, the head portion 11 is integrated with the head portion 11, as shown by the phantom line in FIG. Even if the outer cover member 2 engaged with the portion 11 is disengaged by a fastening operation with a tool or the like, the entire outer cover member 2 is locked in the concave groove 12 to maintain the engaged state and drop or scatter. There is no.
【００５２】 また、図１１（ｂ）に示すように、頭部１１に密着させた外被部材２の係止部 ６を、該頭部１１の外端部に突出させることもあるもので、この係止部６の収縮 力が、外被部材２に対して頭部１１の周縁１３に及ぼすので、同図において仮想 線で示すように、工具等による締結作業により外被部材２が外れても、頭部１１ から外被部材２全体が脱落することがない。Further, as shown in FIG. 11 (b), the locking portion 6 of the jacket member 2 that is brought into close contact with the head portion 11 may be projected to the outer end portion of the head portion 11. Since the contracting force of the locking portion 6 exerts on the peripheral edge 13 of the head portion 11 with respect to the outer cover member 2, the outer cover member 2 is disengaged by a fastening operation with a tool or the like as shown by a virtual line in the figure. Also, the entire jacket member 2 does not fall off the head 11.
【００５３】 図１２において２は、あらかじめ成形した外被部材で、ナット１またはおねじ 体１の頭部１１への係合部２ａと、ナット１のめねじ３における谷径より小径に 成形した係止部６とが構成されている。In FIG. 12, reference numeral 2 denotes a preformed outer casing member, which is formed to have a smaller diameter than the root diameter of the engaging portion 2a of the nut 1 or the male screw body 1 with the head portion 11 and the female screw 3 of the nut 1. The locking portion 6 is configured.
【００５４】 この外被部材２を用いるときは、すでに、取付部材ｂを締結しているナット１ へ外被部材２の係合部２ａを被せ、係止部６がおねじ体４のおねじ５へ当接した とき、該外被部材２を更にナット１側へ押し込むことにより、係止部６がおねじ ５へ密着して螺合状態となる。When this jacket member 2 is used, the engaging portion 2a of the jacket member 2 is already covered on the nut 1 which is fastening the mounting member b, and the locking portion 6 is the external thread of the male screw body 4. When the outer cover member 2 is pressed against the nut 1 side when it comes into contact with the outer cover member 5, the locking portion 6 is brought into close contact with the male screw 5 and screwed.
【００５５】 このとき、係止部６に対して加熱等の収縮加工を施せば、係止部６のおねじ５ への密着性が向上する。At this time, if the locking portion 6 is subjected to shrinkage processing such as heating, the adhesion of the locking portion 6 to the male screw 5 is improved.
【００５６】 この外被部材２は、おねじ体４の頭部（図示せず）に対しても嵌着し得ること はもちろんである。It goes without saying that the outer cover member 2 can also be fitted to the head portion (not shown) of the male screw body 4.
【００５７】[0057]
前述のように構成される本考案の包被ナットによる締結体は、ナットに包被さ れた外被部材は、ナットのおねじ体への螺合と共におねじに一体となっているの で、例え、締結に際してナットの外周に密着していた外被部材が剥がれても、こ の部分の外被部材は係止部に繋がっていて、ナットあるいはおねじ体から離脱す ることがなく、取付部材の付近に散乱してゴミとなることがないもので、これに 起因する該外被部材の混入による機械等への支障を来すことがないと共に、ゴミ となった外被部材を清掃する手間がない。 In the fastening body with the wrapped nut of the present invention configured as described above, the outer jacket member covered with the nut is screwed into the male thread body of the nut and is integrated with the male thread. For example, even if the outer cover member that was in close contact with the outer periphery of the nut is peeled off when tightening, the outer cover member in this part is connected to the locking part and does not separate from the nut or male screw body. It does not scatter in the vicinity of the mounting member and becomes dust, so that it will not interfere with machinery etc. due to mixing of the outer cover member due to this and clean the dusty outer cover member. There is no need to do it.
【００５８】 あるいは、外れた外被部材が締め付け工具であるボックスレンチ内に詰まって 他のナットの締め付けに際して不都合を来すこともない。Alternatively, the detached jacket member does not get stuck in the box wrench which is a tightening tool and causes a trouble when tightening other nuts.
【００５９】 係止部はおねじの山谷部に密着した螺合状態となるので、ナットが緩み方向へ 回ろうとしても、該係止部がおねじとナットのめねじとの間に噛み込まれてナッ トの回転を阻止するから戻り止めとなる。Since the locking portion is screwed into close contact with the crests and valleys of the male screw, even if the nut tries to rotate in the loosening direction, the locking portion is caught between the male screw and the female screw of the nut. As it prevents the nut from rotating, it becomes a detent.
【００６０】 係止部がおねじ体のおねじ部に密着するときは、この部分が締め込みの目印と なるので、ナットより突出したおねじに係止部が位置することで、ナットの締め 忘れの防止となる。 等の格別の効果を奏するものである。When the locking portion comes into close contact with the male screw portion of the male screw body, this portion serves as a mark for tightening. Therefore, when the locking portion is located on the male screw protruding from the nut, the nut is tightened. It will prevent you from forgetting. It has special effects such as.
