[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a nut used for tightening bolts.

〔従来の技術及びその問題点〕[Conventional technology and its problems]

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.

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.

〔この考案が解決しようとする問題点〕[Problem that this idea attempts to solve]

この考案は、埋込みされてもねじ込み方向を変

The object of this invention is to provide a nut whose screwing direction can be changed even if it is embedded.

〔問題点を解決するための手段〕[Means for solving problems]

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.

〔作用〕[Effect]

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.

〔実施例〕〔Example〕

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

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

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

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.

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.
