Abstract

A device including a body having a bottom wall and a cover including a top wall and a sidewall which enclose an interior chamber so that the interior chamber is waterproof to enable the device to be placed in an enclosure where water comes in contact with the device, the interior chamber housing a mechanism by which a shaft or axle supporting a dermabrasion wheel is caused to rotate, the body further including an activation member which when activated causes the shaft and the dermabrasion wheel to rotate in either a counterclockwise direction or a clockwise direction, so that the dermabrasion wheel will peel hardened skin cells from a location on a foot when the location on the foot is placed against the dermabrasion wheel while the dermabrasion apparatus is rotating.

Claims

1. A dermabrasion apparatus comprising:

a. a bottom wall having an exterior surface and an interior surface, a cover having a top wall with an exterior surface and an interior surface with a central opening extending through the top wall from the exterior surface to the interior surface, the top surface of the cover having a pair of oppositely disposed depressions which respectively accommodate a resistance pad, the depressions respectively spaced apart from opposite ends of the central opening, the cover including a sidewall which includes a side opening to accommodate an on-off switch, the sidewall having an exterior surface and an interior surface, the cover fitting over the bottom wall to create an interior chamber surrounded by the interior surface of the bottom wall, the interior surface of the top wall and the interior surface of the sidewall;

b. a central rotating pumice stone which is a wheel having an interior body supporting an axle extending transversely from opposite transverse sides of the body, an exterior rim of the body covered by abrasive material;

c. the rotating pumice stone driven by a DC motor located within the interior chamber and which is electrically connected to a source of power located within the interior chamber, the DC motor and the source of power electrically connected to the on-off switch;

d. an interior shield surrounding the central opening in the cover so that the interior chamber is waterproof;

e. the DC motor connected to a shaft which at its end distal from the DC motor has an offset gear formed to rotate in a given direction, the axle of the wheel having an elongated section which at its distal end has an offset gear which is formed to rotate in a direction opposite from the direction of the offset gear on the DC motor shaft;

f. the cover having a central slot extending into the shield which surrounds the central opening, the axle having a short section which extends transversely to a face of the wheel body and a long section which extends transversely to the face of the wheel body, the wheel partially retained within the central opening of the cover with the short section of the axle retained in a short slot section while the long section of the axle extends past a slot section so that its offset gear is intermeshed with the offset gear on the shaft of the DC motor, the wheel partially extending above the top surface of cover and when the on-off switch is in the “

on”

condition, the DC motor causes its shaft to rotate so that the intermeshed gears of the DC motor and axle cause the wheel to rotate so that the abrasive surface on the wheel facilitates dermabrasion of dead skin cells and calluses on a foot placed against the abrasive surface of the wheel, the wheel located at a central location of the apparatus to provide balance from external forces of a foot pushed against the wheel, the offset opposite orientation of the gears preventing the rotating wheel from flying out of the apparatus; and

g. movement retardation means on the exterior surface of the bottom wall to help prevent the dermabrasion device from moving on a surface onto which it is placed so that the dermabrasion machine including the rotating pumice stone is operated hands free without requiring the dermabrasion machine to be held in a hand.

2. The dermabrasion apparatus in accordance with claim 1 further comprising warning means on the top surface of the cover so that the dermabrasion apparatus is visible in a darkened area.

3. The dermabrasion apparatus in accordance with claim 1 further comprising the bottom wall having an access door on its lower surface to facilitate gaining access to the source of power.

4. The dermabrasion apparatus in accordance with claim 1 further comprising the source of power is at least one battery.

5. A dermabrasion apparatus comprising:

a. a bottom wall having an exterior surface and an interior surface, a cover having a top wall with an exterior surface and an interior surface with a central opening extending through the top wall from the exterior surface to the interior surface, the top surface of the cover having at least one depression which accommodates a resistance pad, the at least one depression spaced apart from an end of the central opening, the cover including a sidewall having an exterior surface and an interior surface, the cover fitting over the bottom wall to create an interior chamber surrounded by the interior surface of the bottom wall, the interior surface of the top wall and the interior surface of the sidewall;

b. a central rotating pumice stone which is a wheel having an interior body supporting an axle extending transversely from opposite transverse sides of the body, an exterior rim of the body covered by abrasive material;

c. the rotating pumice stone driven by a motor located within the interior chamber and which is electrically connected to a source of power located within the interior chamber, the motor and the source of power electrically connected to an on-off switch which is accessible from an exterior surface of a wall of the apparatus;

d. an interior shield surrounding the central opening in the cover so that the interior chamber is waterproof;

e. the motor connected to a shaft which at its end distal from the motor has a first engaging means, the axle of the wheel having an elongated section which at its distal end has a second engaging means;

f. the cover having a central slot extending into the shield which surrounds the central opening, the axle having a short section which extends transversely to a face of the wheel body and a long section which extends transversely to the face of the wheel body, the wheel partially retained within the central opening of the cover with the short section of the axle retained in a short slot section while the long section of the axle extends past a slot section so that its second engaging means is connected to the first engaging means on the shaft of the motor, the wheel partially extending above the top surface of cover and when the on-off switch is in the “

on”

condition, the motor causes its shaft to rotate so that the connected engaging means of the motor and axle cause the wheel to rotate so that the abrasive surface on the wheel facilitates dermabrasion of dead skin cells and calluses on a foot placed against the abrasive surface of the wheel, the wheel located at a central location of the apparatus to provide balance from external forces of a foot pushed against the wheel; and

g. movement retardation means on the exterior surface of the bottom wall to help prevent the dermabrasion device from moving on a surface onto which it is placed so that the dermabrasion machine including the rotating pumice stone is operated hands free without requiring the dermabrasion machine to be held in a hand.

6. The dermabrasion apparatus in accordance with claim 5 further comprising warning means on the top surface of the cover so that the dermabrasion apparatus is visible in a darkened area.

7. The dermabrasion apparatus in accordance with claim 5 further comprising the bottom wall having an access door on its lower surface to facilitate gaining access to the source of power.

8. The dermabrasion apparatus in accordance with claim 5 further comprising the source of power is at least one battery.
