産業上の利用分野
本発明は、外装ケース、飾り板等を、母体となる基板等
に締結する際に用いる締結具に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fastener used for fastening an exterior case, a decorative plate, etc. to a base substrate or the like.
従来例の構成とその問題点
近年、ファクトリ−・オートメーションの発展により自
動ネジ締結機が数多く利用されるようになってきたが、
従来、自動ネジ締結機で締結する際に用いる締結具は、
いずれも第１図に示すよう２／・ −・
に頭部１にネジ部２を設けただけのものである。Conventional configuration and its problems In recent years, with the development of factory automation, many automatic screw fastening machines have come into use.
Conventionally, the fasteners used when fastening with an automatic screw fastening machine are:
In each case, as shown in FIG. 1, a screw portion 2 is simply provided on a head 1 at 2/--.
このため、締結具のセンターと被締結物５の透孔５＆の
センターが第２図のように母体締結部４のネジ孔４１＆
のセンターに対してずれたままで締結しようとした場合
、締結具が母体締結部４へ締結されずに母体締結部４の
近傍で回転するだけになる。Therefore, the center of the fastener and the center of the through hole 5& of the object to be fastened 5 are aligned as shown in
If the fastener is attempted to be fastened while being deviated from the center of the main body fastening part 4, the fastener will not be fastened to the main body fastening part 4 and will only rotate in the vicinity of the main body fastening part 4.
このように上記従来の締結具では、締結具を正確に母体
締結部へ案内することが出来ないという問題を有してい
た。As described above, the above-mentioned conventional fasteners have a problem in that the fasteners cannot be accurately guided to the base fastening portion.
発明の目的
本発明は上記従来の問題点を解消するもので、締結具を
正確に母体締結部に案内することができる締結具を提供
することを目的とする。OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a fastener that can accurately guide the fastener to the base fastening part.
発明の構成
本発明は、ネジ部の先端にネジ部より直径の小さい案内
部を設けた締結具であり、ネジ部の先端に径の小さい案
内部を設けることにより、締結具を母体締結部へ正確に
しかも速やかに案内することができるものである。Composition of the Invention The present invention is a fastener in which a guide portion with a smaller diameter than the threaded portion is provided at the tip of the threaded portion, and by providing the guide portion with a smaller diameter at the tip of the threaded portion, the fastener can be connected to the base fastening portion. It is possible to provide accurate and prompt guidance.

実施例の説明
第３図は本発明の一実施例における締結具の構成を示す
ものである。第３図において、１は頭部２はネジ部で、
これらは従来と実質的に同じものである。３はネジ部３
の先端に設けたネジ部３より径の小さい案内部である。31 Description of Embodiment FIG. 3 shows the structure of a fastener in an embodiment of the present invention. In Fig. 3, 1 is the head 2 is the screw part,
These are substantially the same as conventional ones. 3 is screw part 3
This guide part has a smaller diameter than the threaded part 3 provided at the tip of the guide part.
なお、この案内部３の先端は半球状に形成されている。Note that the tip of this guide portion 3 is formed into a hemispherical shape.
以上のように構成された本実施例の締結具について以下
その動作を説明する。The operation of the fastener of this embodiment configured as described above will be described below.
締結具のセンターが第４図のように母体締結部４のネジ
孔４１Ｌに対してずれた状態でこの締結具を締結しよう
とした場合、ネジ部２よ秋直径が小さくかつ先端が半球
状である案内部３のセンターが母体締結部４のネジ孔４
１Ｌの一部にかかっていれば、案内部３０曲面によりネ
ジ部３がネジ孔りａ内へ案内され、締結が行なえる。If you try to fasten the fastener with the center of the fastener deviated from the screw hole 41L of the base fastening part 4 as shown in Fig. 4, the diameter of the fastener is smaller than that of the threaded part 2 and the tip is hemispherical. The center of a certain guide part 3 is the screw hole 4 of the base fastening part 4
If the guide part 30 is partially engaged, the threaded part 3 is guided into the threaded hole a by the curved surface of the guide part 30, and fastening can be performed.
以上のように本実施例によれば、ネジ部より直径の小さ
い案内部を設けることにより、締結具が母体締結部４の
ネジ孔４＆へ正確に案内されると同時に、ネジ部２の長
さが案内部を設けることにより従来のネジ部の長さに比
べて短かくなるため、それだけ締結時間を短縮できる。As described above, according to this embodiment, by providing the guide portion with a smaller diameter than the threaded portion, the fastener is accurately guided to the threaded hole 4 & of the base fastening portion 4, and at the same time, the length of the threaded portion 2 is By providing the guide portion, the length of the threaded portion is shorter than that of a conventional threaded portion, so the fastening time can be shortened accordingly.
なお上記実施例では頭部形状をブレジャー頭としたが、
頭部形状が第６図のように首下長さに比べ頭部が大きく
、ヘッダーで頭部を成形する場合、首下長さと頭部の関
係上首下長さが短く出来ないので特に有効である。In addition, in the above embodiment, the head shape was a blazer head, but
This is particularly effective when the head shape is large compared to the length under the neck as shown in Figure 6, and when the head is formed using a header, the length under the neck cannot be shortened due to the relationship between the length under the neck and the head. It is.
発明の効果
本発明によれば、ネジ部の先端にネジ部よシ直径の小さ
い案内部を設けたことにより、締結具が母体締結部へ正
確に案内され、さらに案内部の先端の形状を半球状にす
ることにより、母体締結部付前の部品の傷付きが防止で
きるという効果を得ることが出来る優れた締結具を実現
することができる。Effects of the Invention According to the present invention, by providing a guide portion having a diameter smaller than that of the thread portion at the tip of the threaded portion, the fastener is accurately guided to the base fastening portion, and furthermore, the shape of the tip of the guide portion is made into a hemispherical shape. By forming the fastener into a shape, it is possible to realize an excellent fastener that can prevent damage to the parts before the base fastener is attached.
