Description

本考案は、Ｔの字型安全カミソリのカミソリ刃ホ−ルダ−の支持軸を屈曲させることによって、全体的な概形をイの字型にして切れ味を能くした安全カミソリに関するものである。The present invention relates to a safety razor in which the overall shape of the razor blade holder of a T-shaped safety razor is bent so that the overall shape becomes a letter-shaped shape.

従来の安全カミソリはＴの字型をしていて、堅い髭を剃る際には切れ味が今一つという感があった。それは、カミソリ刃ホ−ルダ−の左右方向とハンドルの軸方向とを平面上に投射した位置関係が図１のように垂直になっている為である。Conventional safety razors have a T-shape, and there was a sense of sharpness when shaving a hard beard. This is because the positional relationship in which the horizontal direction of the razor blade holder and the axial direction of the handle are projected on a plane is vertical as shown in FIG.

従来の安全カミソリには、次のような問題点があった。
（イ）Ｔの字型安全カミソリで堅い髭を剃る時の切れ味は、今一つと言う感があったが、それは安全カミソリの形状がＴの字型になっている為に、髭とカミソリ刃の接点と髭の中心とを結ぶ線が、剃り方向と一致しやすい為である。
（ロ）カミソリ刃と髭との接点と髭の中心とを結ぶ線が、一致している為に剃り方向の線に対して鋭角の４０〜４５度をなすような剃り方ができにくい。
そこで、髭を安全で剃りやすく切れ味をよくするために、本案のようなイの字型の形状をした安全カミソリを提供する。Conventional safety razors have the following problems.
(I) The sharpness when shaving a hard beard with a T-shaped safety razor was just one, but because the shape of the safety razor is a T-shape, This is because the line connecting the contact point and the center of the heel easily matches the shaving direction.
(B) Since the line connecting the contact point between the razor blade and the scissors and the center of the scissors is coincident, it is difficult to shave such that an acute angle of 40 to 45 degrees with respect to the line in the shaving direction.
Therefore, in order to improve the sharpness and safety of shavings, we will provide a safety razor that has the shape of a letter like this one.

そこで、Ｔの字型安全カミソリのハンドル（３）の上方に位置する支持軸（２）の中間点（２’’’）において、屈曲部（２’）を施すのであるが、その方法は当初の支持軸（２）の中心線（５’）と上半分の支持軸（２’’）の中心線（５’’）とのなす角が約４５度、且つカミソリ刃ホ−ルダ−（１）の左右方向線（４）とハンドル（３）の中心線（５）とのなす角（図２のような平面上への投射角ａ°）も約４５度になるように、支持軸（２）を当該軸の中間点（２’’’）を中心に左回転方向、又は右回転方向に屈曲させたイの字型安全カミソリである。上述の角度は４５度〜５０度の範囲が適切であることは、幾度にも亘る実験の結果である。
尚、上記の角度（ａ°、ｂ°）が４０〜４５度の時は、料理時に包丁で材料を切る際の切削方向角に類似しているから能く切れる。Therefore, the bent portion (2 ′) is applied at the intermediate point (2 ′ ″) of the support shaft (2) located above the handle (3) of the T-shaped safety razor. The angle formed by the center line (5 ′) of the support shaft (2) and the center line (5 ″) of the upper half support shaft (2 ″) is about 45 degrees, and the razor blade holder (1 ) In the horizontal direction line (4) and the center line (5) of the handle (3) (projection angle a ° on the plane as shown in FIG. 2) is about 45 degrees. This is a U-shaped safety razor in which 2) is bent in the left rotation direction or the right rotation direction around the midpoint (2 ′ ″) of the axis. It is the result of experiments over and over that the above-mentioned angle is appropriately in the range of 45 to 50 degrees.
In addition, when said angle (a degree, b degree) is 40-45 degree | times, since it is similar to the cutting direction angle at the time of cutting material with a kitchen knife at the time of cooking, it cuts efficiently.

本案のイの字型安全カミソリを用いると、従来のような髭剃り時の抵抗を感じなくて比較的軽く滑らかに剃ることができる。又、使用者の左利きや右利きに応じた二種類の形状になっているので、それぞれの使い勝手に応じて使用できる。By using the I-shaped safety razor of the present plan, it is possible to shave relatively lightly and smoothly without feeling the resistance at the time of shaving. Moreover, since it has two types of shapes according to the user's left-handed or right-handed, it can be used according to the ease of use of each.

以下、本考案の実施の形態を説明する。
（イ）Ｔの字型安全カミソリのハンドル（３）の上方における支持軸（２）の中間部において、カミソリ刃ホ−ルダ−（１）の左右方向線（４）とハンドル（３）の中心線（５）とのなす角（図２のような平面上への投射角ａ°）が約４５度になるように支持軸（２）の左回転方向、又は右回転方向の屈曲部（２’）を施す。
（ロ）支持軸（２）の中間点（２’’’）において、支持軸（２）の上半分の支持軸（２’’）の中心線（５’’）と当初の支持軸（２）の中心線（５）とのなす角（図２のような平面上への投射角ｂ°）が約４５度になるように中間点（２’’’）を中心にした左回転方向、又は右回転方向の屈曲部（２’）を支持軸（２）の中間部の両側に施す。
（ハ）上記のイ、ロにおける角度は、４５度よりも小さくても、又５０度よりも大きくても切れ味と効率が悪くなるので、４５度が理想的である。このことは、幾度にも亘る実験の結果判明した。尚、ａ°とｂ°との和は常に９０度である。又、当該ａ°の限界は４５度〜５０度である。
本案は、以上のような構造形態であるが、その使用方法は従来のようにハンドルの中心線方向に引いて用いる。Embodiments of the present invention will be described below.
(B) In the middle of the support shaft (2) above the handle (3) of the T-shaped safety razor, the left-right direction line (4) of the razor blade holder (1) and the center of the handle (3) A bent portion (2 in the left rotation direction or the right rotation direction of the support shaft (2) so that an angle formed with the line (5) (projection angle a ° on a plane as shown in FIG. 2) is about 45 degrees. ').
(B) At the midpoint (2 ′ ″) of the support shaft (2), the center line (5 ″) of the upper half support shaft (2 ″) of the support shaft (2) and the original support shaft (2 ) With the center line (5) (projection angle b ° onto the plane as shown in FIG. 2) is about 45 degrees, and the left rotation direction about the midpoint (2 ′ ″), Alternatively, a bent portion (2 ′) in the right rotation direction is provided on both sides of the intermediate portion of the support shaft (2).
(C) Even if the angle in (a) and (b) is smaller than 45 degrees or larger than 50 degrees, the sharpness and efficiency deteriorate, so 45 degrees is ideal. This became clear as a result of many experiments. The sum of a ° and b ° is always 90 degrees. The a ° limit is 45 ° to 50 °.
The present plan has the above-described structure, but the method of use is used by pulling in the direction of the center line of the handle as in the prior art.

In this case, it cuts well because it is similar to the cutting direction angle when cutting the material with a knife during cooking.
