- the roller shaft is positioned on the extension line of the roller unit shaft, and the roller shaft is perpendicular to the roller unit shaft.
- the roller shaft having rollers at both ends is positioned on the extension line of the roller unit shaft. Therefore, in the traveling direction, it is difficult to secure a trail length that is a distance between the center position of the contact area with the roller on the skin surface and the intersection position of the extension line of the roller unit shaft and the skin surface. Thereby, since the straight running stability of the roller is low and it is difficult to smoothly roll the roller in contact with the skin surface facing various directions, the usability is poor and the usability is likely to deteriorate.
- the caster angle which is the angle formed by the roller unit shaft and the skin surface perpendicular line, can be increased, the trail length can be secured, and straight running stability can be improved.
- the pressing force on the skin surface by the roller tends to decrease, it is difficult to obtain a sufficient massage effect.
- the present invention has been made in view of such a background, and is intended to provide a cosmetic device that is easy to use, provides a good feeling of use, and exhibits a high massage effect.
- One embodiment of the present invention includes a handle; A roller unit in which two rollers are rotatably provided; A roller unit shaft interposed between the roller unit and the handle and rotatably supporting the roller unit with respect to the handle; With When viewed from the axial direction of the roller unit shaft, the axis of the roller unit shaft is in a cosmetic device at a position away from an imaginary straight line passing through the centers of gravity of the two rollers.
- the center of gravity of the roller is located at a position shifted from the axis of the roller unit shaft when viewed from the axial direction of the roller unit shaft. Therefore, when the roller is brought into contact with the skin surface, the trail length can be increased without excessively laying the handle and increasing the caster angle. Therefore, since the straight running stability of the roller is improved, it is easy to make the roller go straight along the skin surface facing various directions without twisting the wrist greatly. Thereby, the usability is improved and the usability is improved. In addition, since it is not necessary to lay the handle excessively against the skin surface, the pressing force on the skin surface by the roller can be maintained. As a result, a high massage effect is achieved.

Abstract
Description
2個のローラーが回転可能に設けられたローラーユニットと、
上記ローラーユニットと上記ハンドルとの間に介在して、上記ハンドルに対して上記ローラーユニットを回転可能に支持するローラーユニットシャフトと、
を備え、
上記ローラーユニットシャフトの軸線方向から見て、該ローラーユニットシャフトの軸線が、上記2個のローラーの両重心を通る仮想直線から離れた位置にある、美容器にある。
上記一対のローラーシャフトは、同一平面上に位置しているとともに、上記ローラーユニットシャフトの軸線に対して傾斜していることが好ましい。この場合には、一対のローラーを肌面に当てた状態で、肌面に平行な方向におけるローラーユニットシャフトの先端側に動かすことにより、一対のローラーによって肌面を押圧することができる。そして、一対のローラーを肌面に平行な方向におけるローラーユニットシャフトの先端側と反対側の基端側に動かすことにより、肌面を摘み上げることができる。これにより、肌面の押圧及び摘み上げによる揉みほぐしの効果が得られ、一層高いマッサージ効果が奏される。
上記美容器の実施例について、以下に説明する。
実施例1における美容器1は、図1、図2に示すように、ハンドル12、ローラーユニット20、及びローラーユニットシャフト30を備えている。
ローラーユニット20には、2個のローラー271、272が回転可能に設けられている。
ローラーユニットシャフト30は、ローラーユニット20とハンドル12との間に介在して、ハンドル12に対してローラーユニット20を回転可能に支持する。
そして、図3に示すように、ローラーユニットシャフト30の軸線方向Pから見て、ローラーユニットシャフト30の軸線303が、2個のローラー271、272の両重心G1、G2を通る仮想直線GLから離れた位置にある。
図1に示すように、美容器1は、略棒状のハンドル12と、ハンドル12の長手方向先端側Y1に位置するローラーユニット20とを備える。ハンドル12は、図2に示すように、ベース体13、第1カバー体14及び第2カバー体15を備える。ベース体13の外周縁全体には、リング状のパッキン17が一体化されて固着されている。パッキン17上には、第1カバー体14の開口内周縁に係合可能なリップ部17aが形成されている。そして、ベース体13に第1カバー体14及び第2カバー体15が装着されて、パッキン17のリップ部17aが第1カバー体14の開口内周縁に圧接されることにより、第1カバー体14と第2カバー体15との隙間からハンドル12の内部に水が侵入することを防止している。これにより、ハンドル12の内部のベース体13に備えられた電装品に水が及ばないようにしている。
本例の美容器1によれば、ローラーユニットシャフト30の軸線方向Pから見て、ローラーユニットシャフト30の軸線303からずれた位置にローラー271、272の重心G1、G2が位置することとなる。そのため、ローラー271、272を肌面60に当接させる際に、ハンドル12を過度に寝かせなくとも、トレール長TLを大きくできる。そのため、ローラー271、272の直進安定性の向上が図られることから、手首を大きく捻ることなく、ローラー271、272を様々な方向に面する肌面60に沿わせて直進させやすい。これにより、使い勝手が良くなるとともに、使用感が良好となる。また、ハンドル12を肌面60に対して過度に寝かせる必要がないため、ローラー271、272による肌面60への押圧力を維持することができる。その結果、高いマッサージ効果が奏される。
実施例1における美容器1はローラーユニット20を1個備えていたが、実施例2における美容器1は、図11に示すように一対のローラーユニット201、202を備える。一対のローラーユニット201、202はそれぞれ、実施例1におけるローラーユニット20と同等の構成を有する。そして、一対のローラーユニット201、202に備えられる4個のローラー271、272、273、274の重心G1、G2、G3、G4は、同一平面上に位置することができるように構成されている。さらに、一対のローラーユニット201、202は、図11に示すように、それぞれのローラーユニットシャフト30の軸線が同一平面S1上に位置するように、ハンドル12の中心を通る仮想直線L1を基準に対称に配置されている。図12に示すように、本例ではそれぞれのローラーユニットシャフト30の軸線303が同一平面上におけるなす角γは120°となっている。
実施例2における美容器1はローラーユニット20を一対備えていたが、実施例3における美容器1は、図13に示すように二対のローラーユニット201、202、203、204を備えている。二対のローラーユニット201、202、203、204はそれぞれ、実施例1におけるローラーユニット20と同等の構成を有する。

上記実施例6では、図26に示すように、一対のローラーユニット201、202は、ハンドル12の両端側Y1、Y2の側周面に設けられていたが、本例の美容器1は、図30、図31に示すように、一対のローラーユニット201、202は、ハンドル12の第1端部側Y1の側周面にそれぞれ設けられている。そして、一対のローラーユニットシャフト30は、同一直線L2上に位置している。
本例の美容器1では、図32に示すように、円柱状のハンドル12の側周面において、第1端部側Y1に第1ローラーユニット201が設けられ、第2端部側Y2に第2ローラーユニット202が設けられる。そして、第1ローラーユニット201の回転軸線303と、第2ローラーユニット202の回転軸線303とは、互いにねじれの位置に位置している。

そして、図36に示すように、所定の側方Y2から見て、隣り合う少なくとも2個のローラー支持体201、202における回転軸線303は、ハンドル12から下方Z2に進むにつれて互いに離隔している。
図34、図35、図37に示すように、美容器1は、略棒状のハンドル12を備える。本例では、ハンドル12は、図38、図39に示すように、上述の実施例と同様にベース体13、第1カバー体14及び第2カバー体15を備え、さらに第2カバー体15の内側には、一端方向Y1の端部及び他端方向Y2の端部に、グリス151、152がそれぞれ設けられている。
また、図48、図49に示すように、美容器1は、8個のローラー271~278が同一平面S3に接することができるように構成されている。
