【考案の詳細な説明】
この考案はノブとキャップ内部に設けた中子とを係合し
たキャップ付のノック式シャープペンシルに関する。[Detailed Description of the Invention] This invention relates to a knock-type mechanical pencil with a cap that engages a knob with a core provided inside the cap.
従来のキャップ付のノック式シャープペンシルは、キャ
ップをノブに嵌合するためキャップをノブより取外す時
にノブも共に外れてしまったり、ノブと軸筒との間に軸
方向への余分の動きがあったり又ノブにキャップの取付
位置を決めるための突起が外観に出てしまう等の欠点を
有していた。Conventional knock-type mechanical pencils with caps fit the cap onto the knob, so when the cap is removed from the knob, the knob also comes off, or there is excessive movement in the axial direction between the knob and barrel. Also, it has drawbacks such as a protrusion that is visible on the knob for determining the mounting position of the cap.
この考案はこのような欠点を解消し、しかも簡単な組立
により得られるキャップ付のノック式シャープペンシル
この考案を図面に基づいて説明すると、第１図はキャッ
プ１が軸筒２の後端より突出している外パイプ３に嵌合
している図である。This invention eliminates these drawbacks and is a knock-type mechanical pencil with a cap that can be obtained through simple assembly.This invention will be explained based on the drawings.Figure 1 shows that the cap 1 protrudes from the rear end of the barrel 2. It is a diagram showing the outer pipe 3 being fitted.
さらに詳細に説明すると、軸筒２の内部には芯を漸次繰
り出すチャック機構を備えた中部吊体が構成されている
。To explain in more detail, inside the shaft tube 2, there is constructed a middle hanging body equipped with a chuck mechanism for gradually feeding out the core.
そして中部吊体の後部に位置する芯タンク４の適所には
角孔４Ａが明けられ、該角孔４Ａに外パイプ３の内壁に
設けた突起３Ａが落し込まれて嵌着されている。A square hole 4A is formed at a suitable position in the core tank 4 located at the rear of the middle hanging body, and a projection 3A provided on the inner wall of the outer pipe 3 is inserted into the square hole 4A.
このように取付られた外パイプ３の外径は軸筒２の内径
２Ａより小径に形成され軸筒内を摺動できるように構成
されている。The outer diameter of the outer pipe 3 attached in this manner is smaller than the inner diameter 2A of the shaft cylinder 2, and is configured to be able to slide inside the shaft cylinder.
さらに外パイプ３の後方周面には第２図に示すようにキ
ャップ１と嵌合するための凸条３Ｂが設けられ、該凸条
３Ｂにキャップ１内径が取り外し自在に密嵌する。Furthermore, as shown in FIG. 2, a protrusion 3B is provided on the rear circumferential surface of the outer pipe 3 for fitting with the cap 1, and the inner diameter of the cap 1 is removably tightly fitted into the protrusion 3B.
又凸条３Ｂより後方の小径段部３Ｃにはノブ５が嵌合係
止される。Further, a knob 5 is fitted and locked to the small diameter stepped portion 3C rearward of the protrusion 3B.
このノブ頭部５Ａはキャップ内部に固着された中子６の
前端６Ａに当接させられキャップ開孔端１Ａと軸筒２の
後端２Ｂとの間にノック移動距離より大きな長さを有す
るように構成されている。The knob head 5A is brought into contact with the front end 6A of the core 6 fixed inside the cap, and has a length greater than the knock movement distance between the cap opening end 1A and the rear end 2B of the shaft tube 2. It is composed of

ップ開孔端１Ａとの間にノック移動距離より大きな長さ
を有するためにキャップ１をノックし芯を繰り出すこと
ができる。In the knock-type mechanical pencil with a cap configured in this way, when the cap 1 is removed from the tip of the barrel and fitted into the protrusion 3B at the rear of the outer pipe 3, the core 6 inside the cap 3 will fit into the head 5A of the knob 5. The cap 1 can be knocked and the lead can be drawn out because the cap 1 is in contact with the cap 1 and there is a longer distance between the barrel rear end 2B and the cap opening end 1A than the knock movement distance.
又キャップ１のノックにより中子６、ノブ５、外パイプ
３を介して中部吊体の一部である芯タンク４を押すので
軸方向の余分な動きがなく、シかもキャップ１と係止す
るための突起は外観に現われない。In addition, the knock of the cap 1 pushes the core tank 4, which is a part of the middle hanging body, through the core 6, the knob 5, and the outer pipe 3, so there is no unnecessary movement in the axial direction, and the cap 1 is locked with the cap 1. The protrusions for this purpose do not appear on the outside.
又キャップを外す場合においてもノブが外れるという心
配がないと同時に外観上の美しさも兼ね備えかつ接着と
かかしぬとかの複雑な組立加工を行なわずに圧入や落し
込みなどによってきわめて簡単に組立加工が行なえると
いう実用上多大な効果を有するものである。In addition, when removing the cap, there is no need to worry about the knob coming off, and at the same time it has a beautiful appearance, and can be assembled very easily by press-fitting or dropping, without having to perform complicated assembly processes such as gluing and screwing. This has a great practical effect.
