Abstract

A beauty treatment device having a device body, a drive unit provided in the device body and a patter driven by the drive unit wherein the patter is composed of a freely rotating roller; and freely rotating space guide wheels for maintaining the range of patting motion of the roller by depressing an object being patted, and roller supports disposed on an axis coinciding with the center of the space guide wheels for supporting the shaft of the roller off-center with respect to the space guide wheels, so that the patter pats the object being patted.

Claims

1. A beauty treatment device, comprising a device body, a drive unit in said body, a roller support rotatably mounted in said body about a support axis, a patter having a shaft rotatably mounted on said roller support about a shaft axis, said shaft axis being offset from said support axis so that said shaft is eccentrically mounted on said roller support for eccentric rotation relative to said roller support, said patter having an outer periphery with a diameter which is driven through an eccentric path, a bearing rotatably mounted in said device body for rotation about said support axis, means connecting said drive unit to said roller support for rotating said roller support, and a spacer wheel rotatably mounted on said bearing and being of a diameter at most smaller than the diameter of said outer periphery of said patter so as to engage against the skin and position the device so that rotation of said patter causes said patter to pat the skin.

2. A beauty treatment device according to claim 1, including a transmission shaft having a transmission shaft gear, said drive unit including a motor having a motor shaft with a gear engaged with said transmission shaft gear for rotation of said transmission shaft, said body having a housing plate portion on each side of said transmission shaft rotatably supporting said transmission shaft, and transmission gear means extending from said transmission shaft to said roller support and effecting rotation of said roller support with rotation of said motor shaft.

3. A beauty treatment device as set forth in claim 1 wherein said roller support comprises which are provided in such a manner as to support both ends of said shaft.

4. A beauty treatment device as set forth in claim 1 wherein said drive unit consists of a motor and a plurality of gears provided in multi-stages for transmitting the rotation of said motor to said roller supports.

5. A beauty treatment device as set forth in claim 4 wherein said gears in said drive unit consist of a worm gear fixedly fitted to a rotating shaft of said motor, a worm wheel in mesh with said worm gear, a worm shaft to which said worm wheel is fixedly fitted, a first spur gear fixedly fitted to sail worm shaft, an idle gear in mesh with said first spur gear, and a second spur gear in mesh with said idle gear to drive said roller support.

6. A beauty treatment device as set forth in claim 1 wherein said patter is supported at both end faces thereof by resilient cushioning rubber.

7. A beauty treatment device according to claim 1, wherein said patter comprises a roller having a cylindrical surface.

8. A beauty treatment device according to claim 7, wherein said cylindrical surface of said patter is of uniform diameter.

9. A beauty treatment device as set forth in claim 1, wherein said patter includes two separate patter portions which are spaced with respect to said shaft axis, said roller support being disposed between said patter portions.

10. A beauty treatment device according to claim 1, wherein said patter includes an outer cushion portion which carries said outer periphery.
