Description
本考案は化粧用具、筆記具などに使用する金属製、樹脂製等の丸パイプの端部における斜め切口を閉じるキャップ構造に関する。 The present invention relates to a cap structure that closes an oblique cut at the end of a round pipe made of metal, resin, or the like used for cosmetic tools, writing tools, and the like.
従来、金属製等の丸パイプＡの端部における斜め切口Ｂを閉じるキャップ構造としては、図４のように丸パイプＡ内への挿入部の先端に斜め切口Ｂの外形に対応した蓋本体Ｃを設けた構造のものとなっているが、一体成形のできる合成樹脂製か鋳造製のものとなっているのが一般的である。ところが合成樹脂製では強度に難点があり、又成形、鋳造では金型が必要になるだけでなく、丸パイプの直径が５〜２０ｍｍのような細いもののキャップとなると精巧さを期待することができないなどの難点があり、殊に少ロット生産に際しては上記も金型、鋳造設備ではコスト高になり使用に耐え得ない。又切削の金属加工では殊に挿入部と蓋本体の交差部分が鋭角状になっている部分はエンドミル加工、バイト加工をすることができない。 Conventionally, as a cap structure for closing the oblique cut B at the end of the round pipe A made of metal or the like, a lid body C corresponding to the outer shape of the oblique cut B at the tip of the insertion portion into the round pipe A as shown in FIG. However, it is generally made of synthetic resin that can be integrally molded or cast. However, there is a difficulty in strength in the case of synthetic resin, and not only a mold is required for molding and casting, but it is impossible to expect elaboration when it becomes a cap of a thin pipe with a round pipe diameter of 5 to 20 mm. In particular, when producing a small lot, the above-mentioned mold and casting equipment are expensive and cannot be used. Further, in the metal processing for cutting, the end mill processing or the bite processing cannot be performed particularly in the portion where the intersecting portion of the insertion portion and the lid main body has an acute angle.
そこで本考案は、丸パイプの端部斜め切口を塞ぐキャップを、金属の切削加工によって提供しようとするものである。 Therefore, the present invention intends to provide a cap that closes the oblique cut end of the round pipe by metal cutting.
丸パイプ内に固定自在な中子と金属製のキャップとよりなり、中子には中心孔を設けてキャップを固定自在とし、キャップは前記中心孔に挿入し固定自在な軸部と、丸パイプの端部における斜め切口の外形に対応したキャップ本体とよりなるものである。
尚丸パイプは金属製に限らず樹脂製でも良く、端部の斜め切口に強度を持たせる場合などに利用することができる。又中子は金属以外の素材でもよい。
It consists of a core that can be fixed inside the round pipe and a metal cap. The core is provided with a center hole so that the cap can be fixed. The cap is inserted into the center hole and can be fixed, and the round pipe. And a cap body corresponding to the outer shape of the oblique cut at the end of the.
Note that the round pipe is not limited to metal but may be made of resin, and can be used for giving strength to the oblique cut end. The core may be made of a material other than metal.
本考案の効果として、中子もキャップも工作機械における切削工具を使用して金属加工によって製造できるので、成形装置、鋳造装置などの金型は必要なく少ロット生産が可能となり、且つ精巧なキャップ構造ができ、しかもキャップ本体にも簡単に装飾などを施すことができ、有益である。 As an effect of the present invention, both the core and the cap can be manufactured by metal processing using a cutting tool in a machine tool, so that it is possible to produce a small lot without using molds such as a molding device and a casting device, and an elaborate cap. It is useful because it is structured and the cap body can be easily decorated.
金属製の丸パイプＡ内に固定自在な中子１とキャップ２とよりなり、中子１には後述の軸部４を挿入固定する中心孔３を設けてある。この中子１は金属製のものがよいが、使用目的によっては樹脂製などでもよい。 The core 1 includes a core 1 and a cap 2 that can be fixed in a metal round pipe A. The core 1 is provided with a center hole 3 for inserting and fixing a shaft portion 4 to be described later. The core 1 is preferably made of metal, but may be made of resin depending on the purpose of use.
キャップ２は、前記中心孔３に挿入し固定自在な軸部４と、丸パイプＡの端部における斜め切口Ｂの外形に対応したキャップ本体５とよりなるものである。 The cap 2 includes a shaft portion 4 that can be inserted and fixed in the center hole 3 and a cap body 5 that corresponds to the outer shape of the oblique cut B at the end of the round pipe A.
実際の金属加工に際しては、殊にキャップ２の加工にあっては図２のように所要箇所に工作機械における切削工具のエンドミル、バイトを当てて切削する。 In actual metal processing, particularly when processing the cap 2, as shown in FIG. 2, an end mill or a cutting tool of a cutting tool in a machine tool is applied to a required portion for cutting.
本考案は以上のようになるもので、これを筆記具６のキャップとなる丸パイプＡ内の所要深さに中子１を固定し、この中子１の中心孔３にキャップ２の軸部４を挿入し接着剤により固定しキャップ本体５と斜め切口Ｂを密接させる。図示しない化粧道具などのキャップとしても使用でき、その他の用具としても使用できる。 The present invention is as described above. The core 1 is fixed to a required depth in the round pipe A to be a cap of the writing instrument 6, and the shaft portion 4 of the cap 2 is inserted into the center hole 3 of the core 1. Is inserted and fixed with an adhesive, and the cap body 5 and the oblique cut B are brought into close contact with each other. It can be used as a cap for a cosmetic tool (not shown), and can also be used as other tools.
