Abstract
A drive unit operates an applicator for massage, brushing, cleaning, and the like. The drive unit moves the applicator in a unique translatory motion in which the plane of the applicator maintains an unchanging orientation relative to the drive unit and has a lapping or stroking action on the body of the user which is effectively unidirectional at the body surface. This motion is very effective for many applications in which reciprocating or rotational movement is less appropriate, such as stimulating the blood circulation, brushing the teeth, and hair grooming, and different applicators as well as drive units are provided which are particularly adapted to accomplish these functions.
Claims6
An applicator drive unit for treating a surface comprising:
- a casing;
- a pair of generally parallel rods mounted in said casing, each of said rods having a pair of eccentric portions;
- a mounting bracket mounted to the eccentric portions of said rods;
- an applicator element attached to said mounting bracket;
- a motor operatively mounted in said casing;
- power transmission means operatively connecting said motor and mounting bracket for driving said mounting bracket circularly on the eccentric portions of said rods such that all portions of the applicator element have substantially translational circular motion whereby the orientation of the applicator element with respect to the casing is maintained substantially constant and the applicator has a lapping action in use to produce substantially one effective direction of motion relative to the surface treated.
