DETAILED DESCRIPTION

The invention will be understood from the following detailed description of embodiments of the invention, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features are not described in detail.

The reference numbers have been used to point out elements in the embodiments described and illustrated herein, in order to facilitate the understanding of the invention. They are meant to be merely illustrative, and not limiting. Also, the foregoing embodiments of the invention have been described and illustrated in conjunction with systems and methods thereof, which are meant to be merely illustrative, and not limiting.

FIG.1is in an exploded perspective view of a brushing accessory according to one embodiment of the invention.

A brushing accessory10such as for soaping, according to one embodiment of the invention, includes a motorized member50A and a brushing member50B, including holes26A and26B at a first side and a brush18at its second side.

FIG.2is the exploded perspective view ofFIG.1from another angle of view.

Connecting motorized member50A to brushing member50B inserts pin24A of motorized member50A into hole26A and pin24B into hole26B of brushing member50B.

FIG.3is a sectional view of the motorized and brushing members ofFIG.1.

A motor32rotates a central gear54C.

Referring again toFIG.2, equal gears54A and54B are interlaced with central gear54C, one opposite to the other, thus they rotate at equal speeds.

The interlacing of gears54A and54B to central gear54C disposes pins24A and24B at the same side.

FIG.4is a top view of the opposing gears at the state ofFIG.3.

Pins24A and24B are shown disposed at the left, enumerated64A.

FIG.5is the top view of the opposing gears upon rotating 90 degrees.

Since gears54A and54B are equal, and pins24A and24B are equally distanced58, once pin24A is disposed up enumerated64B, pin24B as well is disposed up, and the virtual line60therebetween maintains its angle, to the angle of the state ofFIG.5, being horizontal according to the examples.

FIG.6depicts4locations of one of the pins ofFIG.2, and the disposition of the brush member for each of the dispositions.

Pins24A and24B extend from gears54A and54B respectively, and having the equal distances58between center20and center22A and22B of the gears.

In case pin24A is disposed at location64A, brush18is disposed at zone62A; in case pin24A is disposed at location64B, brush18is disposed at zone62B; in case pin24A is disposed at location64C, brush18is disposed at zone62C; and in case pin24A is disposed at location64D, brush18is disposed at zone62D.

Zone62A is left to zone62C, thus providing a left to right back and forth motion to brush18; zone62B is above zone62D, thus providing a top to bottom back and forth motion to brush18; and zone62A is below and left to zone62B, thus providing a 45 degrees back and forth motion to brush18. Considering the states between these 4 shown states, brush18moves back and forth in all directions.

This brushing movement is further advantaged in applying equal distances and speeds to all points of the user's body, being in contrast to symmetric rotating of a brush, or even to eccentric rotating of a brush applying a higher distance and speed away from the center of the rotation.

FIG.7is a side view of the brushing accessory ofFIG.1including an elevator.

Brushing accessory10may include an elevator44, for brushing various heights.

FIG.8is a front view of the brushing accessory ofFIG.7.

The user may move left and right in relation to the elevator ofFIG.7.

FIG.9is a top view of a brushing accessory according to another embodiment of the invention at a first position.

Gears54A and54B are elliptic, and are interlaced with one another. Motor32rotates gear38, being interlaced with gear40. Gear40is fixed to elliptic gear54B for rotating it.

Thus motor32rotates elliptic gear54B, being interlaced with elliptic gear54A.

Hinge22B of gear54B is fixed to stationary plate55(shown inFIG.2), whereas hinge22A of gear54A is slidable57within a rail59fixed to plate55.

Pin24A extends from gear54A into hole26A of brushing member50B ofFIG.1having brush18.

FIG.10is the exploded perspective view for the embodiment ofFIG.9.

Brushing accessory10includes motorized member50A and brushing member50B, including hole26A at a first side and a brush18at its second side.

FIG.11is a top view of the brushing accessory ofFIG.9at a second position of the elliptic gears.

Gears54A and54B are interlaced with one another even though they are elliptic as shown by the two different positions of gears54A and54B ofFIG.9and ofFIG.10.

FIG.12is a perspective view showing the produced motion of the brush.

An elastic band or other springy element63draws (61) hinge22A towards hinge22B for ensuring the interlacing of elliptic gear54A with elliptic gear54B, in spite of the sliding therebetween

Thus, in one aspect, the invention is directed to a brushing accessory (10), including:a brushing member (50B), including a brush (18); anda motorized member (50A), including a motor (32) including a first gear (54C), and including a second gear (54A) interlaced with the first gear (54C),

wherein the diameter of the second gear (54A) is of several centimeters,thereby the second gear (54A) moves the brush (18) several centimeters at least back and forth.

The brushing accessory (10) may further include:a third gear (54B) interlaced with the first gear (54C),

thereby the back and forth moving of the brush is along all directions.Centers of (22A,22B,20) of the first, second and third gears may be disposed along a virtual line (60).

The second (54A) and third (54B) gears may be equal.

The brush (18) may be connected to a point (24A) of the second gear (54A) and to a point (24B) of the third gear (54B),and the points (24A,24B) may be equally distanced (58) each from the center (22A) of that gear.

The interlacing of the second (54A) and third (54B) gears may dispose the points (24A,24B) at an equal side.

In another aspect, the invention is directed to a brushing accessory (10), including:a first member (50B), including a hole (26A) and a brush (18) fixed thereto; anda second member (50A), includinga) a motor (32) for rotating a first elliptic gear (54B);b) a second elliptic gear (54A) interlaced with the first elliptic gear (54B); andc) a pin (24A) extending from the second elliptic gear (54A) into the hole (26A) of the first member (50B),thereby moving the brush (18) on a user's body as a function of changing locations of the pin (24A), the locations changing as a function of the interlacing of the elliptic gears.

The brushing accessory (10) may further include:a rail (59) for allowing sliding a hinge (22A) of the second elliptic gear (54A).

The brushing accessory (10) may further include:a springy element (63) for drawing the second elliptic gear (54A) towards the first elliptic gear (54B), for interlacing therebetween.
