この考案はボルトの締め付けにつかわれるナツ
トに関する。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a nut used for tightening bolts.
ナツトは外周面が多角面状でその中心に雌ねじ
孔を形成したものが一般的である。
Nuts generally have a polygonal outer peripheral surface and a female screw hole formed in the center.
ところで、例えば、第8図に示すように、ベア
リング1を一体にした合成樹脂製軸受2に、その
成形時に多角ナツト3を埋込んだものにおいて
は、ボルト4をナツト3にねじ通し支軸Aに圧接
して軸受2を支軸Aに取付けたりする。しかしな
がら埋込みであるため、ボルト4のねじ込み方向
(軸方向)は固定されており、その方向にボルト
4を圧接してはいけない部分がある場合、そのナ
ツト3による締付けを行なうことができず、ま
た、ねじ込み方向の圧接面に孔が形成されている
場合など十分な締付け力を得ることができず、軸
受2を強固に取付けることができないなどの問題
が生じている。 By the way, for example, as shown in FIG. 8, in a case where a polygonal nut 3 is embedded in a synthetic resin bearing 2 with a bearing 1 integrated therein at the time of molding, a bolt 4 is threaded through the nut 3 and the support shaft A is inserted. The bearing 2 is attached to the support shaft A by pressure contact with the support shaft A. However, since it is embedded, the screwing direction (axial direction) of the bolt 4 is fixed, and if there is a part in that direction where the bolt 4 should not be pressed, the nut 3 cannot be tightened. In cases where a hole is formed in the pressure contact surface in the screwing direction, sufficient tightening force cannot be obtained, and the bearing 2 cannot be securely mounted.
この考案は、埋込みされてもねじ込み方向を変
えることができるナツトを提供することを課題と
する。
The object of this invention is to provide a nut whose screwing direction can be changed even if it is embedded.
上記課題を達成するため、この考案のナツトに
あつては、球体の中心の両側を平面により切断し
た形状で、その両切断面間に軸が前記中心をずれ
たねじ孔を形成した構成としたものである。
In order to achieve the above object, the nut of this invention has a shape in which both sides of the center of a sphere are cut by planes, and a screw hole whose axis is offset from the center is formed between the two cut surfaces. It is something.
この様に構成すれば、埋込んだ後でも、埋込み
面が球面となるため、ねじ孔に棒を挿通してその
軸方向を任意の方向に変えることができその所望
方向にボルトをねじ通す。
With this configuration, even after embedding, since the embedding surface becomes a spherical surface, the axial direction of the rod can be changed to any direction by inserting the rod into the screw hole, and the bolt can be screwed in the desired direction.
以下、この考案の実施例を添付図面に基づいて
説明する。 Hereinafter, embodiments of this invention will be described based on the accompanying drawings.
第1図及び第2図に示すように、球体をその中
心に対し対称な平面で切断した中央部分形状と
し、その両切断面間に軸bが前記球体の中心軸a
とずれたねじ孔5を形成してナツト3を構成す
る。
As shown in FIGS. 1 and 2, a sphere is cut in a central part shape by a plane symmetrical to its center, and an axis b is defined between the two cut planes as the central axis a of the sphere.
The nut 3 is formed by forming a screw hole 5 that is offset from the screw hole 5.
このナツト3を例えば第8図のごとく軸受2な
どの被取付物に埋込んで使用すると、第2図及び
第3図に示すようにその埋込面6も球面となつて
いるため、ねじ孔5に棒を挿通してその軸方向を
任意の方向に変え得る。この際、このナツト3
は、球体の中心の両側を平面で切断した形状であ
るため、その外周面には球体の直径径の円周が存
在しその円周が埋込面6からはずれないかぎり抜
け落ちることがない。 When this nut 3 is embedded in an object to be mounted, such as a bearing 2, as shown in FIG. 8, the embedding surface 6 is also spherical, as shown in FIGS. By inserting a rod through 5, the axial direction can be changed to any direction. At this time, this nut 3
Since it has a shape in which both sides of the center of the sphere are cut by planes, there is a circumference of the diameter of the sphere on its outer peripheral surface, and it will not fall off unless the circumference deviates from the embedded surface 6.
ナツト3を任意のねじ孔方向位置にセツトした
のち、ボルト4をねじ通す。この際、ねじ孔5の
軸bが球体中心からずれているため、ねじ込み力
によりナツトが回転することがない。 After setting the nut 3 at an arbitrary position in the direction of the screw hole, the bolt 4 is screwed through. At this time, since the axis b of the screw hole 5 is offset from the center of the sphere, the nut will not rotate due to the screwing force.
なお、このナツト3を埋込む際、第1図乃至第
3図に示すように、そのねじ孔5の偏心位置を全
てのナツト3において同一とするため、偏心方向
を示す孔7などの印を形成するとよい。 In addition, when embedding this nut 3, as shown in FIGS. 1 to 3, in order to make the eccentric position of the screw hole 5 the same in all nuts 3, a mark such as hole 7 indicating the eccentric direction is marked. It is good to form.
ナツト3の形状としては、上記実施例以外に第
4図乃至第7図に示すものなども考えられる。第
4図は球体の一側を切断してねじ孔5を形成した
もの、第5図は球体にねじ孔5を形成したもので
あり、両実施例においては、ねじ孔5の開口が切
断面となる。第6図は第1図実施例のねじ孔5の
軸bを軸aに平行でなくしたもの、第7図は切断
面を平行でなくしたものである。 As for the shape of the nut 3, in addition to the above-mentioned embodiments, the shapes shown in FIGS. 4 to 7 may also be considered. Fig. 4 shows a sphere in which one side is cut to form a screw hole 5, and Fig. 5 shows a sphere in which a screw hole 5 is formed.In both embodiments, the opening of the screw hole 5 is on the cut surface. becomes. 6 shows an embodiment in which the axis b of the screw hole 5 of the embodiment shown in FIG. 1 is not parallel to the axis a, and FIG. 7 shows an embodiment in which the cut plane is not parallel to the axis a.
この考案は以上のように構成したので、埋込ん
でボルト締め用として使用する際、そのねじ込み
方向を変化できる効果がある。
Since this invention is constructed as described above, it has the effect of being able to change the screwing direction when it is embedded and used for bolt tightening.
