Description

本発明は、介在部材、締付具、及び被締付体に関し、これらのいずれかを少なくとも傷つけることなく取り外しすることができない、介在部材、締付具、及び被締付体に関する。   The present invention relates to an interposed member, a fastening tool, and a clamped body, and more particularly to an interposed member, a clamping tool, and a clamped body that cannot be removed without damaging at least any of them.

例えば、鉄塔とその台座とを連結するネジ、体育館の天井で使用されているネジ、橋で使用されているネジなどは、一旦、締め付けした後に、外れないことが望ましい。特に、このようなものは、悪質ないたずら等により、不要にネジが外されると、大事故につながりかねない。   For example, it is desirable that a screw for connecting a steel tower and its pedestal, a screw used on the ceiling of a gymnasium, a screw used on a bridge, and the like do not come off after being tightened. In particular, such a thing can lead to a major accident if the screw is unnecessarily removed due to a malicious mischief or the like.

また、モータなどの回転体を備える電気機器は振動によりネジが弛むことがある。このため、この種の機器は、ネジの弛み具合のチェックなどのメンテナンスを行うことが必要である。しかし、一旦締め付けしたネジが、ネジ又は被締付体を傷つける、或いは、破壊しない限り、その後に外れないようにすることができれば、面倒なメンテナンスが不要になり望ましい。   In addition, a screw may loosen due to vibration in an electric device including a rotating body such as a motor. For this reason, it is necessary for this type of equipment to perform maintenance such as checking for looseness of screws. However, it is desirable that troublesome maintenance is unnecessary if the screw once tightened can be prevented from coming off unless the screw or the body to be fastened is damaged or destroyed.

ここで、特許文献1には、軟質ワークの下穴にネジ込まれたタッピンネジの弛み止め効果を得るために、頭部の座面に、ネジ込み方向回転側は傾斜の緩い斜面となっており、ネジ緩め方向回転側は前記斜面より傾斜のきつい斜面となっている、外周方向へ延びる突条が形成されているタッピンネジが記載されている。
特開平11−013726号公報
Here, in Patent Document 1, in order to obtain the effect of preventing loosening of the tapping screw screwed into the pilot hole of the soft work, the rotation surface in the screwing direction is a slanted surface with a gentle slope. In addition, there is described a tapping screw in which a ridge extending in the outer peripheral direction is formed, the rotation side of the screw loosening direction being a steep slope inclined from the slope.
Japanese Patent Laid-Open No. 11-013726

しかし、特許文献1に記載されているタッピンネジは、あくまで、弛み止め効果があるだけで、通常の使用態様下、つまり、ネジを破壊等することない状況下において、ネジが弛まないというものではない。したがって、振動によるネジの弛み、ネジを外すいたずらに対して、万全ではなかった。   However, the tapping screw described in Patent Document 1 only has a locking effect, and does not mean that the screw does not loosen under a normal usage mode, that is, in a situation where the screw is not destroyed. . Therefore, it was not perfect for the loosening of the screw due to vibration and the mischief of removing the screw.

そこで、本発明は、通常の使用態様下において、外れないネジを提供することを課題とする。   Then, this invention makes it a subject to provide the screw which does not remove | deviate under a normal usage condition.

上記課題を解決するために、本発明は、中央にネジの脚部を通す貫通孔が形成されていて、ネジと当該ネジの被締付体との間に介在される介在部材において、
前記貫通孔の中央軸線から放射状に延在している頂部と、前記ネジとの対向面に略直角の面であって前記ネジが弛むことを防止する防止面とを含む刻み目部が、表面及び裏面に形成されていることを特徴とする。
In order to solve the above-mentioned problem, the present invention is provided with an intermediate member in which a through-hole through which a leg portion of a screw is passed is formed at the center and interposed between the screw and a tightened body of the screw.
A notch portion including a top portion extending radially from a central axis of the through hole and a surface substantially perpendicular to a surface facing the screw and preventing the screw from loosening, the surface and It is formed on the back surface.

また、本発明は、頭部と、当該頭部の中央から延びる脚部とを含み、当該脚部がネジ切りされているネジと、
中央に前記ネジの脚部を通す貫通孔が形成されていて、前記ネジと当該ネジの被締付体との間に介在される介在部材とを備える締付具において、
前記ネジと前記介在部材との各対向面のうち少なくとも硬性が高い方に、前記貫通孔の中央軸線から放射状に延在している頂部と、前記対向面に略直角の面であって前記ネジが弛むことを防止する防止面とを含む第1刻み目部が、形成されていて、かつ、
前記貫通孔の中央軸線から放射状に延在している頂部と、前記ネジとの対向面に略直角の面であって前記ネジが弛むことを防止する防止面とを含む第2刻み目部が、前記介在部材の前記対向面の裏面に形成されていることを特徴とする。
In addition, the present invention includes a head and a leg portion extending from the center of the head portion, and a screw in which the leg portion is threaded,
In a fastener having a through hole through which a leg portion of the screw passes in the center, and an interposed member interposed between the screw and a tightened body of the screw,
Of the opposing surfaces of the screw and the interposition member, at least the one having higher hardness, a top portion extending radially from the central axis of the through hole, and a surface substantially perpendicular to the opposing surface, the screw A first notch portion including a preventive surface for preventing the slackening of the material, and
A second notch portion including a top portion extending radially from a central axis of the through-hole and a prevention surface which is a surface substantially perpendicular to a surface facing the screw and prevents the screw from loosening; It is formed in the back surface of the said opposing surface of the said interposed member, It is characterized by the above-mentioned.

さらに、本発明の被締付体は、ネジの脚部を通すネジ穴と、
前記ネジ穴の周辺に位置する、当該ネジ穴の中央軸線から放射状に延在している頂部と、前記ネジ穴形成面に略直角の面であって前記ネジが弛むことを防止する防止面とを含む刻み目部とが形成されていることを特徴とする。
Furthermore, the to-be-tightened body of the present invention includes a screw hole through which a leg portion of the screw passes,
A top portion that is located in the periphery of the screw hole and extends radially from the central axis of the screw hole; and a surface that is substantially perpendicular to the screw hole forming surface and prevents the screw from loosening. And a notch portion including the feature.

更に、刻み目部は、前記防止面の底辺と前記頂部との間に位置する、平面状又は曲面状の傾斜部を有している。   Furthermore, the notch portion has a flat or curved inclined portion located between the bottom of the prevention surface and the top.

本発明によると、ネジ、介在部材、及び被締付体の各接触面の少なくとも一方に、刻み目部を有するため、ネジが、弛む方向に回ることがない。したがって、ねじは、通常の使用態様下において、外れなくなる。   According to the present invention, since the notch portion is provided in at least one of the contact surfaces of the screw, the interposed member, and the tightened body, the screw does not rotate in the loosening direction. Therefore, the screw does not come off under normal use.

以下、本発明の実施の形態について、図面を用いて説明する。なお、図面は、本発明の実施形態の説明の都合上、一部を誇張して描いてある。したがって、実際の製品は、部材の数、寸法及び比率については図示されているものに限定されるわけではないことに留意されたい。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, a part of the drawings is exaggerated for convenience of explanation of the embodiment of the present invention. Therefore, it should be noted that the actual product is not limited to the number, size and ratio of members as shown.

図1(a)は、本発明の実施形態のネジ(雄ネジ)10の模式的な側面図である。図1(b)は、図1(a)のネジ10の斜視図である。図1(c)は、図1(a)のネジ10の底面図である。   FIG. 1A is a schematic side view of a screw (male screw) 10 according to an embodiment of the present invention. FIG. 1B is a perspective view of the screw 10 of FIG. FIG.1 (c) is a bottom view of the screw 10 of Fig.1 (a).

図1(a)に示すように、ネジ10は、頭部11と、頭部11の底面中央から下方へ延びる脚部13とに大別される。頭部11の底面であって脚部13の周辺には、刻み目部12が、形成されている。ネジ10は、刻み目部12を含め、例えば金型によって製造されている。   As shown in FIG. 1A, the screw 10 is roughly divided into a head 11 and a leg 13 extending downward from the center of the bottom surface of the head 11. A notch portion 12 is formed on the bottom surface of the head portion 11 and around the leg portion 13. The screw 10 includes the notch 12 and is manufactured by a mold, for example.

図1(b)に示すように、頭部11の上面には、例えば、中央にマイナスドライバの先端を受ける、すりわり部14が形成されている。なお、頭部11は、プラスドライバ用に十字孔が形成されていてもよい。更には、頭部11は、ドライバ対応型ではなく例えばスパナ対応型でもよいし、ボルトタイプでもリベットタイプでもよい。このように、頭部11は、使用工具に応じて形状等を変更することが可能であり、図示するようなドーム状ではなく、円柱状でもよいし、六角柱状でもよい。   As shown in FIG. 1B, the upper surface of the head 11 is formed with a sliding portion 14 that receives the tip of a minus driver at the center, for example. The head 11 may be formed with a cross hole for a plus driver. Furthermore, the head 11 may be a spanner compatible type instead of a driver compatible type, a bolt type or a rivet type. As described above, the head 11 can be changed in shape or the like according to the tool used, and may have a columnar shape or a hexagonal column shape instead of a dome shape as illustrated.

図1(c)に示すように、刻み目部12は、頭部11の底面に対して緩勾配を為す第1面12aと、頭部11の底面に対して略直角を為す第2面12bとを含み、これらが交互に配置されている。図1には、いわゆる右ネジ用の刻み目部12を示している。   As shown in FIG. 1C, the notch 12 includes a first surface 12 a that forms a gentle gradient with respect to the bottom surface of the head 11, and a second surface 12 b that forms a substantially right angle with respect to the bottom surface of the head 11. These are alternately arranged. FIG. 1 shows a notch 12 for a so-called right screw.

ここで、本実施形態では、略直角とは、90度のみならず100度程度までの角度のことをいう。90度に近いほど、ネジ10の弛み防止に好適である。一方、100度に近いほど、ネジ10の締め付けの労力が軽減される。この角度は、ネジ10、後述する介在部材20及びこれらの被締付体の硬性、ネジ10を締め付ける際の力などに応じて決定すればよい。   Here, in this embodiment, the substantially right angle means not only 90 degrees but also an angle up to about 100 degrees. The closer to 90 degrees, the better the loosening of the screw 10 is. On the other hand, the closer to 100 degrees, the lighter the tightening effort of the screw 10 is reduced. This angle may be determined according to the screw 10, the hardness of the interposed member 20 to be described later and the tightening bodies thereof, the force when tightening the screw 10, and the like.

また、第1面12aと第2面12bとが交わる頂部は、脚部13の中央軸線から放射状に延在している。第1面12aの底面は、内周から外周に向けて深くなる。外周における第1面12aと第2面12bとの為す角度は、頂部の数が増えるほど増える。   In addition, the top portion where the first surface 12 a and the second surface 12 b intersect extends radially from the central axis of the leg portion 13. The bottom surface of the first surface 12a becomes deeper from the inner periphery toward the outer periphery. The angle formed between the first surface 12a and the second surface 12b on the outer periphery increases as the number of apexes increases.

刻み目部12と脚部13との間は、ネジ10と介在部材20とが隙間なく合致するように、抉られた形状としている。なお、第1面12aは、平面状のものを図示しているが、曲面状であってもよい。また、特に、頂部の数は、ピッチは、図示するものに限定されない点に留意されたい。   Between the notch portion 12 and the leg portion 13, the screw 10 and the interposition member 20 are shaped so as to be matched with no gap. The first surface 12a is a flat surface, but may be a curved surface. In particular, it should be noted that the number of apexes is not limited to the pitch shown in the figure.

図2(a)は、本発明の実施形態の介在部材20の模式的な側面図である。図2(b)は、図2(a)の介在部材20の斜視図である。図2(c)は、図2(a)の介在部材20の上面(底面)図である。   Fig.2 (a) is a typical side view of the interposition member 20 of embodiment of this invention. FIG. 2B is a perspective view of the interposition member 20 of FIG. FIG.2 (c) is an upper surface (bottom surface) figure of the interposition member 20 of Fig.2 (a).

図2(a)〜図2(c)に示すように、介在部材20は、中央にネジ10の脚部13が通される開口部23が形成されている。介在部材20の大きさは、ネジ10の頭部11の底面よりも大きくしてある。また、介在部材20の両面には、図1に示す刻み目部12と同様の条件で、刻み目部21,22がそれぞれ形成されている。刻み目部21,22は、図示するように、介在部材20の表裏(上面底面)を気にすることなく使用可能とされている。   As shown in FIGS. 2A to 2C, the interposition member 20 has an opening 23 through which the leg portion 13 of the screw 10 passes in the center. The size of the interposed member 20 is larger than the bottom surface of the head 11 of the screw 10. In addition, notches 21 and 22 are formed on both surfaces of the interposition member 20 under the same conditions as the notches 12 shown in FIG. The notch portions 21 and 22 can be used without worrying about the front and back surfaces (upper surface bottom surface) of the interposition member 20, as shown.

なお、本実施形態では、刻み目部21,22は、刻み目部12と同じ条件で形成しているが、例えば、各刻み目部における目の粗さ比を、例えば1:2、或いは2:1のようにしてもよい。   In the present embodiment, the notch portions 21 and 22 are formed under the same conditions as the notch portion 12, but the roughness ratio of the eyes in each notch portion is, for example, 1: 2 or 2: 1. You may do it.

図3は、図1に示すネジ10及び図2に示す介在部材20の使用例を示す図である。図3には、図1に示すネジ10及び図2に示す介在部材20の他に、被締付体であるところのボード100,200を示している。ボード100,200は、例えば樹脂などから成る。   FIG. 3 is a diagram illustrating a usage example of the screw 10 illustrated in FIG. 1 and the interposition member 20 illustrated in FIG. 2. 3, in addition to the screw 10 shown in FIG. 1 and the interposition member 20 shown in FIG. 2, boards 100 and 200 which are to-be-tightened bodies are shown. The boards 100 and 200 are made of, for example, resin.

ボード100,200には、それぞれ、ネジ10を受けるネジ穴101,201が形成されている。ネジ穴101の周辺には、介在部材20に形成している刻み目22に対応する刻み目102が形成されている。刻み目102は、ネジ穴101の形成時に一体的に形成してもよいし、ネジ穴101とは別個に形成してもよい。別個に形成する場合の一例として、ポンチ等の工具を用いるとよい。   Screw holes 101 and 201 for receiving the screws 10 are formed in the boards 100 and 200, respectively. A notch 102 corresponding to the notch 22 formed in the interposed member 20 is formed around the screw hole 101. The notch 102 may be formed integrally when the screw hole 101 is formed, or may be formed separately from the screw hole 101. A tool such as a punch may be used as an example of forming separately.

ボード100,200を相互に連結するときには、まず、ボード100,200のネジ穴101,201の位置合わせを行う。それから、ネジ10の脚部13を、介在部材20の開口部23に通してから、ネジ穴101に合わせる。そして、図示しないマイナスドライバ等によって、ネジ10を時計回りに回転させることによって、ネジ穴101内にネジ込んでいく。   When the boards 100 and 200 are connected to each other, first, the screw holes 101 and 201 of the boards 100 and 200 are aligned. Then, the leg portion 13 of the screw 10 is passed through the opening 23 of the interposition member 20 and then aligned with the screw hole 101. Then, the screw 10 is screwed into the screw hole 101 by rotating the screw 10 clockwise by a minus driver or the like (not shown).

すると、ネジ10の先端は、ボード100のネジ穴101内を通過し、ボード200のネジ穴102に達する。引き続き、ネジ10を回転させると、ネジ10は、ネジ穴201内に進行していく。   Then, the tip of the screw 10 passes through the screw hole 101 of the board 100 and reaches the screw hole 102 of the board 200. When the screw 10 is subsequently rotated, the screw 10 advances into the screw hole 201.

ここで、刻み目部12,21,22が対応関係にあり、かつ、第1面12a,21a,22aが共に緩勾配にあるので、介在部材10の有無に拘わらず、ボード100,200に対するネジ10の締め付けは容易である。   Here, since the notches 12, 21, and 22 are in a corresponding relationship and the first surfaces 12 a, 21 a, and 22 a are all in a gentle gradient, the screw 10 for the boards 100 and 200 regardless of the presence or absence of the intervening member 10. Tightening is easy.

一方、第2面12b,21b,22bは全て、頭部11の底面に対して略直角であるので、一旦、ネジ10をボード100,200に対して締め付けた後に、ネジ10を反時計回りに回転させることができない。このため、ボード100,200からネジ10を取り外すには、ネジ10を破壊等しない限り行えない。したがって、ボード100,200が振動等しても、メンテナンスなく長期使用をしても、ネジ10が弛むことがない。   On the other hand, since the second surfaces 12b, 21b, and 22b are all substantially perpendicular to the bottom surface of the head 11, once the screw 10 is fastened to the boards 100 and 200, the screw 10 is turned counterclockwise. It cannot be rotated. For this reason, the screws 10 cannot be removed from the boards 100 and 200 unless the screws 10 are destroyed. Therefore, even if the boards 100 and 200 vibrate or the like, even if they are used for a long time without maintenance, the screw 10 does not loosen.

ここで、介在部材20の硬性が、ボード100,200の硬性よりも高い場合には、刻み目部22がボード100,200にめり込むことで、強固な接続が可能となる。このため、介在部材20に刻み目102が形成されていることは必須の条件ではない。同様の理由により、ネジ10と介在部材20とのうち、硬性が低い方には、刻み目部を形成することは必須の条件ではない。   Here, when the hardness of the interposition member 20 is higher than the hardness of the boards 100 and 200, the notch 22 is recessed into the boards 100 and 200, so that a strong connection is possible. For this reason, it is not an essential condition that the notch 102 is formed in the interposition member 20. For the same reason, it is not an indispensable condition to form a notch portion in the screw 10 and the interposition member 20 having a lower hardness.

なお、介在部材20を用いることなく、ネジ10を直接ボード100,200に取り付けることも可能である。しかし、ネジ10の頭部11の底面よりも介在部材20の方が大きいので、より強いトルクが生じる。したがって、介在部材20を用いた方がボード100,200とネジ10との接続を強固にすることが可能になる。   The screw 10 can be directly attached to the boards 100 and 200 without using the interposition member 20. However, since the interposed member 20 is larger than the bottom surface of the head 11 of the screw 10, a stronger torque is generated. Therefore, the connection between the boards 100 and 200 and the screw 10 can be strengthened by using the interposition member 20.

また、ネジ10をボルトタイプとする場合には、ボード200の図面裏面側にもネジ穴201の周囲に刻み目部を形成し、かつ、ナットにも対応する刻み目部を形成するとよい。さらに、ネジ10等に、弛み防止剤を塗布したり、締め付け時等に発生する熱によってネジ10とボード100,200とを溶着させるための薬品等を塗布したりして、より強固な接続を行ってもよい。   When the screw 10 is a bolt type, a notch portion may be formed around the screw hole 201 on the back side of the board 200 in the drawing, and a notch portion corresponding to the nut may be formed. Furthermore, a loosening preventive agent is applied to the screw 10 or the like, or a chemical or the like for welding the screw 10 and the boards 100 and 200 is applied by heat generated at the time of tightening or the like. You may go.

図4は、ネジ10の他の実施形態を示す図である。図4には、刻み目部12の頂部を曲線状としている。図示のように頂部を曲線状にすると、ネジ10と介在部材20との間で、強いトルクが実現でき、締め付け後のネジ10の弛みを更に防止することが可能となる。なお、図4に示すネジ10を用いる場合には、当然に、介在部材20の刻み目部21,22の形状、ボード100の刻み目部102の形状も、これに対応する形状とすることは言うまでもない。   FIG. 4 is a view showing another embodiment of the screw 10. In FIG. 4, the top of the notch 12 is curved. When the top portion is curved as shown in the figure, a strong torque can be realized between the screw 10 and the interposition member 20, and loosening of the screw 10 after tightening can be further prevented. Needless to say, when the screw 10 shown in FIG. 4 is used, the shape of the notches 21 and 22 of the interposition member 20 and the shape of the notch 102 of the board 100 are of course corresponding to this. .

図5は、ネジ10の別の実施形態を示す図である。図5には、刻み目部12の頂部の数を図1に示すものから極端に減らしている。このように、刻み目部12の目を粗くすると、目の欠け等がなくなる、保存時の目詰まりがなくなるなどのメリットがある。なお、図4に示すネジの場合にも、頂部の曲線のアールを、図4に示しているものよりも小さくし、頂部の間隔を増やし、頂部の数を減らしてもよい。   FIG. 5 is a view showing another embodiment of the screw 10. In FIG. 5, the number of the tops of the notches 12 is extremely reduced from that shown in FIG. As described above, when the notched portion 12 is made coarse, there are merits such as no missing eyes and clogging during storage. In the case of the screw shown in FIG. 4 as well, the radius of the top curve may be made smaller than that shown in FIG. 4 to increase the distance between the tops and reduce the number of tops.

その他、図1等では、ネジ10と介在部材20との接触面を平面状としているが、例えば、ネジ10側を凸状にし、介在部材20側を凹状にすることで、これらの接触面積を増やし、高トルクを実現してもよい。また、ネジ10と介在部材20とを一体化してもよい。具体的には、底部に刻み目部が形成されている鍔部を設けて、介在部材20の機能をネジ10に備えるようにしてもよい。   In addition, in FIG. 1 etc., although the contact surface of the screw 10 and the interposition member 20 is planar, for example, by making the screw 10 side convex and making the interposition member 20 side concave, these contact areas are reduced. It may be increased to achieve high torque. Further, the screw 10 and the interposition member 20 may be integrated. Specifically, a collar portion having a notch portion formed at the bottom may be provided so that the screw 10 has the function of the interposition member 20.

本発明は、ネジ産業全般において、広く利用することが可能である。特に、建設業、土木業、電気業にも利用することができる。   The present invention can be widely used in the screw industry in general. In particular, it can also be used for construction, civil engineering, and electrical industries.
