Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
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.
Claim 2
Dependent Claim
131 words
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.
Claim 3
Dependent Claim
43 words
Structure according to claim 1 wherein said rods comprise rigid shafts rotationally mounted in said bracket, said mounting bracket being journalled on said eccentric portions, and including means restricting said shafts to in-phase motion whereby said applicator is restricted to substantially translational motion.
Claim 4
Dependent Claim
61 words
Structure according to claim 1 wherein said applicator element has a plurality of substantially parallel hair-engaging elements projecting therefrom, and with respect to said one effective direction of motion, each of said hair-engaging elements has a streamlined portion on the leading side and a cavitation-inducing portion on the trailing side to harbour particulate foreign matter extracted from the hair and scalp.
Claim 5
Dependent Claim
45 words
Structure according to claim 1 wherein said rods are resilient and centrally mounted in said casing, said bracket being engaged on the ends of said rods whereby said rods are attached toward the individual centers of the circular motion undergone by said mounting bracket portions.
Claim 6
Dependent Claim
24 words
Structure according to claim 4 and including a drive shaft generally parallel to and between said rods and having eccentric portions engaging said bracket.
Claim 7
Dependent Claim
40 words
Structure according to claim 4 wherein said casing has a portion thereof dimensioned to fit in the human mouth, said mounting bracket is disposed in said casing portion, and said applicator element is provided with bristles adapted to tooth brushing.
