目的
この考案は安全かみそりの組立刃体の改良に係るもので
あって、揺動可能にホルダに取付けられた組立刃体の揺
動運動を滑らかにすることを目的とする。[Detailed description of the invention] Purpose This invention relates to the improvement of the assembled blade of a safety razor, and its purpose is to smooth the rocking motion of the assembled blade that is swingably attached to the holder. do.
首振り安全かみそりは肌の起伏に合わせて常に最適なひ
げそり角度を得られるようにするためのものである。Oscillating safety razors are designed to ensure that the optimum shaving angle is always obtained according to the undulations of the skin.
安全かみそりの刃先が肌の起伏にうまく適合するために
は組立刃体の揺動が滑らかでなければならない。In order for the cutting edge of a safety razor to properly adapt to the undulations of the skin, the blade assembly must swing smoothly.
従来からの首振りの構造として、組立刃体の裏側にジャ
ーナル軸受が一定の間隔を置いて設けられ、このジャー
ナル軸受にホルダの先端部からアーム形に突出したジャ
ーナル軸が入り、こジャーナル軸を中心に組立刃体が揺
動するという方法がとられている。As a conventional swinging structure, journal bearings are provided at regular intervals on the back side of the assembled blade body, and a journal shaft that protrudes from the tip of the holder in an arm shape is inserted into this journal bearing. A method is used in which the assembled blade body swings around the center.
他方両ジャーナル軸受の中間地点の組立刃体裏側には二
つの斜面が角度をもって連続するカム面が設けられ、該
カム面にホルダの先端中央部から上下に摺動可能に突出
したカム従動装置が弾性的に押圧することによって揺動
した組立刃体を元の位置に復帰させる。On the other hand, on the back side of the assembled blade body at the midpoint between both journal bearings, a cam surface is provided with two slopes continuous at an angle, and a cam follower is provided on the cam surface, which protrudes from the center of the tip of the holder so as to be able to slide up and down. By elastically pressing, the oscillated assembled blade body is returned to its original position.
このカム従動装置の押圧力が強すぎると組立刃体は揺動
しにくくなる。If the pressing force of this cam follower is too strong, the assembled blade becomes difficult to swing.
逆にカム従動装置の押圧力か弱すぎると組立刃体は元の
位置に復帰しなくなり、肌の起伏に適合しなくなる。On the other hand, if the pressing force of the cam follower is too weak, the assembled blade will not return to its original position and will not conform to the undulations of the skin.
組立刃体が適度にかつ滑らかに揺動するためにはカム従
動装置の押圧力が適度であることに加えてカムとカム従
動装置の接触が滑らかであることも必要である。In order for the assembled blade body to swing appropriately and smoothly, it is necessary that the pressing force of the cam follower is appropriate and that the contact between the cam and the cam follower is smooth.
従来例はカム面が平面だったので摩擦が大きかった。In the conventional example, the cam surface was flat, so friction was large.
これに対して本考案はこの摩擦が少なくて滑らかな揺動
の組立刃体を提供することを目的とする。In contrast, an object of the present invention is to provide an assembled blade body that has less friction and swings smoothly.
