この考案は低価格のノック式シャープペンシルを得るた
めに軸を分割したことを特徴とする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 characterized by having a split shaft in order to obtain a knock-type mechanical pencil at a low price.
従来のノック式シャープペンシルは第１図に示すように
、チャック１に締リング２を装着するためにチャック１
と芯タンク３は別体で構成され、締リング２、連結具４
およびスプリング５を装着後にスプリング５の弾発力下
でチャック１と芯タンク３を装着したりかしめたりして
連結していたので高価なうえに組立能率が悪かった。As shown in Fig. 1, a conventional knock-type mechanical pencil has a chuck 1 to attach a tightening ring 2 to the chuck 1.
and the core tank 3 are constructed separately, including a tightening ring 2 and a connecting tool 4.
Moreover, after the spring 5 was installed, the chuck 1 and the core tank 3 were connected by being installed and caulked under the elastic force of the spring 5, which was expensive and had poor assembly efficiency.
この考案は上述したような欠点をなくしてチャックと芯
タンクからなる中部品体をあらかじめ固着して一体化す
るとか、又は、中部品体を合成樹脂等で一体に成形し、
これらを分割した軸の中に組み入れるという構成によっ
て組立能率を上げるとともに低価格のノック式シャープ
ペンシルを提供することを目的としたものである。This idea eliminates the above-mentioned drawbacks by fixing and integrating the middle part consisting of the chuck and the core tank in advance, or by integrally molding the middle part with synthetic resin, etc.
The purpose of this invention is to increase assembly efficiency by incorporating these into a divided shaft, and to provide a knock-type mechanical pencil at a low price.
尚このようなチャックと芯タンクを一体にして組み立て
るものとしては実開昭５１−１０９２３５号があるが、
これはつぎに述べるような欠点がある。In addition, there is a method for assembling such a chuck and a core tank in one piece, such as Utility Model Application No. 51-109235.
This has drawbacks as described below.
っまり軸筒１２の端部１２ａに圧入した２個の略半円筒
形状をしたチャック、リング係合部材１８゜１８の軸方
向の寸法に誤差が出た場合、っまり長すぎた場合には先

重大欠陥になり、又、後者ではノックの度に係合部材が
摺動してたいへん不快であるといった問題のほか、さら
に組立時にチャック及びリングを軸筒の前端より相当量
突出させなければ係合部材が取り付けられず、細管を長
く加工する必要があり、加工が面倒であったり破損しや
すい等の欠点がある。If there is an error in the axial dimension of the two approximately semi-cylindrical chucks and ring engaging members 18°18 that are press-fitted into the end 12a of the shaft cylinder 12, or if they are too long, In addition to the problem that a gap is created between the tip and the retaining member, the former causes a serious defect in appearance, and the latter causes the engaging member to slide every time there is a knock, which is extremely uncomfortable. During assembly, the engaging member cannot be attached unless the chuck and ring protrude a considerable amount from the front end of the shaft cylinder, and the thin tube must be machined to be long, which has drawbacks such as troublesome processing and easy breakage.
この考案の構成を第２図及び３図の図面にもとづいて説
明すると、軸６は第３図に示すように二つに分割されて
いて各片の合わせ面６Ａの位置には凸部６Ｂ及び凹部６
Ｃをはめ合わせることによって第２図のごとくずれのな
い完全な円筒形の軸６に構成される。The structure of this device will be explained based on the drawings of FIGS. 2 and 3. As shown in FIG. Recess 6
By fitting C, a completely cylindrical shaft 6 with no distortion is formed as shown in FIG.
、又、軸６の先端外側にはねじ部６Ｄが、内側には前内
鍔６にと後向鍔６Ｆにより構成された凹溝６Ｅが設けら

けられて構成されている。Also, a threaded portion 6D is provided on the outside of the tip of the shaft 6, and a groove 6E formed by the front inner flange 6 and the rearward flange 6F is provided on the inside, and the rear portion is provided with a groove 6E that connects with the head 7. A fitting stage 6G is provided.
そして軸６の後向鍔６Ｆの内径６Ｈはチャック１０１が
芯８を保持しないで閉じた状態での頭部１０１Ａ外径よ
り細径に構成されている。The inner diameter 6H of the rearward flange 6F of the shaft 6 is configured to be smaller than the outer diameter of the head 101A when the chuck 101 is closed without holding the core 8.
一方線リング１０２の内径１０２Ａはチャック１０１が
芯８を保持しないで閉じた状態での頭部１０１Ａ外径よ
り太径に構成されている。On the other hand, the inner diameter 102A of the wire ring 102 is configured to be larger than the outer diameter of the head 101A when the chuck 101 is closed without holding the core 8.
。そしてこれらの部品は第２図に示すように後部に芯タ

いる。. These parts include the head 10 of the chuck 101 which integrally constitutes the core tank 103 at the rear as shown in FIG.
The tightening ring 102 fitted on the outer periphery of the shaft 6 is loosely fitted into the concave groove 6E of the shaft 6, and the rear inner collar 6F and the stepped portion 103 of the core tank 103
The elastic force of the spring 105 stretched between the core 8 and the
A cap 10 having a core holder 9 inside is screwed into the threaded portion 6D of the shaft 6, and a crown 7 is fitted into the fitting step 6G. ing.
このようなノック式シャープペンシルを組み立てるには
、チャック１０１に芯タンク１０３を一体に固着して中
部品体を構成し、チャック１０１の先端１０１Ｂよりス
プリング１０５および締リング１０２を挿入する。To assemble such a knock-type mechanical pencil, the lead tank 103 is integrally fixed to the chuck 101 to form a middle part body, and the spring 105 and the tightening ring 102 are inserted from the tip 101B of the chuck 101.
尚チャックと芯タンクは必ずしも固着する必要はなく、
射出成形等で一体に構成しても何ら問題はない。In addition, the chuck and core tank do not necessarily need to be firmly attached.
There is no problem even if it is constructed integrally by injection molding or the like.
つぎに二つ割された一方の半割の軸６の凹溝６Ｅに締リ
ング１０２を遊嵌するとともに軸６の後内鍔６Ｆと芯タ
ンク１０３の段部１０３Ａとの間にスプリング１０５を
張架し、該半割の軸６に他方の半割の軸６を、互いの軸
６の凹部６Ｃに凸部６Ｂを圧入して円筒形の軸６を構成
する。Next, a tightening ring 102 is loosely fitted into the groove 6E of the shaft 6 of one half of the shaft 6, and a spring 105 is tensioned between the rear inner flange 6F of the shaft 6 and the stepped portion 103A of the core tank 103. The shaft 6 of the other half is press-fitted into the shaft 6 of the other half, and the convex portion 6B is press-fitted into the recess 6C of each shaft 6 to form a cylindrical shaft 6.
そしてこの軸６のねじ部６Ｄに口金１０を螺合させ、嵌
合段６Ｇに頭冠７を固着させることにより、軸６は半割
づつに開くことはない。By screwing the cap 10 onto the threaded portion 6D of the shaft 6 and fixing the crown 7 to the fitting step 6G, the shaft 6 will not open in half.
以上で組立が完了し、このように組み立てられたノック
