Description
【考案の詳細な説明】
この考案はノブを押すことにより、シャープペンシル用
の芯を繰り出したり、筆記体を出没させたりする金属製
の軸を有する筆記具に関する。[Detailed Description of the Invention] This invention relates to a writing instrument having a metal shaft that allows a mechanical pencil lead to be drawn out or a writing body to appear and disappear by pressing a knob.
従来、金属製の軸を有する筆記具は、軸自体あるいは軸
の後部に突出して取り付けられた頭冠によりノブ摺動孔
が構成されていた。Conventionally, in writing instruments having a metal shaft, the knob sliding hole was formed by the shaft itself or by a crown protrudingly attached to the rear of the shaft.
よって軸や頭冠が金属製の場合、ノブが摺動するたびに
こすれて作動が悪かったり、ノブに傷がついて外観をそ
こねたり、携帯時の振動によりノブと、軸あるいは頭冠
とが当接して金属音が生じたいへん不快感を与えていた
。Therefore, if the shaft or crown is made of metal, the knob may rub every time it slides, resulting in poor operation, or the knob may be scratched, deteriorating its appearance, or the knob and shaft or crown may become damaged due to vibrations when carrying the device. When they came into contact, a metallic sound was produced, which caused a very unpleasant feeling.
そこでこの考案は自己潤滑性合成樹脂からなる内冠を金
属製の軸の内部に固着し、内冠の内径をノブ摺動孔にす
ることにより上記の欠点を解消したものである。Therefore, this invention solves the above-mentioned drawbacks by fixing an inner crown made of self-lubricating synthetic resin inside a metal shaft and making the inner diameter of the inner cap a knob sliding hole.
ついでこの考案の構成を第１図にもとづいて説明すると
、金属製の軸１の後部内側１人に圧入あるいは接着によ
り内冠２を固着する。Next, the structure of this invention will be explained based on FIG. 1. An inner crown 2 is fixed to the rear inner side of a metal shaft 1 by press-fitting or gluing.
該内冠２はノブ摺動孔２Ａが、ノブ３の外径３Ａと同等
かわずかに大径に、かつ内冠２の後端２Ｂが軸１の後端
１Ｂより突出することがないようにして構成されている
。The knob sliding hole 2A of the inner crown 2 has a diameter equal to or slightly larger than the outer diameter 3A of the knob 3, and the rear end 2B of the inner crown 2 does not protrude beyond the rear end 1B of the shaft 1. It is composed of
芯タンク４の後部内側４Ａには消しゴムケース５を被嵌
した消しゴム６が嵌合されていて、該消しゴム６を覆う
ようにノブ３が後部外側４Ｂに嵌合され、軸１の後端１
Ｂより突出している。An eraser 6 fitted with an eraser case 5 is fitted to the rear inner side 4A of the lead tank 4, and a knob 3 is fitted to the rear outer side 4B so as to cover the eraser 6.
It stands out from B.
以上のように構成されたこの考案は、ノブを押すことに
よりノブと内冠との間で摺動しながら接触してもノブに
傷が付かず作動がなめらかであるとともに、携帯時ある
いは筆記時におけるノブと軸の当接音もなく、さらに内
冠が軸の外面に突出していないために、品格を損ねるこ
ともないなど多大の効果を有するものである。This device configured as described above allows for smooth operation without damaging the knob even when the knob and the inner cap slide and come into contact with each other when the knob is pressed, and also allows for smooth operation when carrying or writing. There is no contact noise between the knob and the shaft, and since the inner crown does not protrude from the outer surface of the shaft, it does not impair the quality of the shaft.
