A device for providing elliptical path motion to skin or other surface. The device includes a motor, shaft, and a cam having at least one offset axis cam lobe for creating offset motion. A mounting bracket assembly that has a pair of arms associated with the motor can be moved by the cam in an elliptical path having X-axis, Y-axis and, in exemplary embodiments, Z-axis movement. The mounting bracket assembly may have two brackets, each being associated with an oscillating plate. Each oscillating plate may have a plurality of protrusions or tufts of bristles protruding therefrom. Elliptical movement of the oscillating plates creates offset elliptical motion of the protrusions associated with each oscillating plate. A fluid delivery system may be incorporated to provide fluid through the device. The device may be used for cleaning, stimulation or treatment of skin. |

1. An apparatus for providing elliptical motion, comprising:
a) a motor; b) a drive shaft having an axis of rotation and extending from the motor, the shaft having a distal end; c) an elliptical motion creating mechanism associated with the shaft, the mechanism including at least one axially offset member having an axis of rotation in an axis offset from the axis of the shaft; d) a mounting bracket comprising
i) a base plate operatively associated with the offset member, the base plate having a first side defining an X-axis movement direction and a second side generally perpendicular to the first side, the second side defining a Y-axis movement direction,ii) a first side arm extending from the base plate and associated with the motor, the first side arm having a distal end terminating in a connection portion, the first side arm defining a Z-axis movement direction,iii) a second side arm extending from the base plate and associated with the motor, the second side arm having a distal end terminating in a connection portion; and, e) a second axially offset member and a second mounting bracket, the second mounting bracket comprising
i) a base plate operatively associated with the offset member, the base plate having a first side defining an X-axis movement direction and a second side generally perpendicular to the first side, the second side defining a Y-axis movement direction,ii) a first side arm extending from the base plate and associated with the motor, the first side arm having a distal end terminating in a connection portion, the first side arm defining a Z-axis movement direction, andiii) a second side arm extending from the base plate and associated with the motor, the second side arm having a distal end terminating in a connection portion, wherein the second mounting bracket is associated with the second offset member such that the first and second mounting brackets are adapted to each move in a separate and offset elliptical path, and whereby rotation of the shaft causes the offset members to rotate and impart elliptical motion to the mounting brackets such that the base plates move in an elliptical path in both the X-axis and Y-axis directions. |
