Abstract

The core components of the invention are a frame, an upper carriage rail assembly, a lower carriage rail assembly, a brush, and two motor assemblies. The carriage rail assemblies are housed within a waterproof cover. The top of the cover is configured as a hood to protect the upper carriage rail assembly from water damage. The frame mounts onto the shower wall through the use of suction cups. The carriage assembly attaches to the frame through the use of screws on the frame and keyhole shaped mounting holes on the cover. The brush mounts onto an upper carriage assembly and a lower carriage assembly through the use of flanges. A stepper motor located on the upper carriage assembly drives a pulley system, allowing the brush to move horizontally from left to right and then from right to left. A panel of control buttons provide start and stop options, allowing the operator to increase or decrease the speed of the horizontal movement of the brush across the upper and lower carriage rails, and permitting the operator to start and stop the brush motion.

A complete back scrubber comprising:

a cover, the cover having a top side, a front side, a back side, and a bottom side, the cover configured as a rectangle wherein the rectangle encloses a central transparent portion;
a first flange and a second flange;
a first set of four wheels and a second set of four wheels, wherein the first set of four wheels is operatively connected to the first flange and the second set of four wheels is operatively connected to the second flange;
a first rail and a second rail, wherein the first rail and the second rail are parallel to each other, arranged horizontally, the first rail configured to receive the first set of four wheels and the second rail configured to receive the second set of four wheels;
a first support bracket and a second support bracket, wherein the first support bracket and the second support bracket are parallel to each other and are arranged vertically;
a frame, wherein the frame comprises a front and a back, and at least one mounting screw, wherein the at least one mounting screw has a knob end to operatively engage within a corresponding opening located on the back side of the cover;
a plurality of suction cups located on the back of the frame and releaseably holding the frame on a shower wall;
a battery, wherein the battery is positioned at a location on the top side of the cover, the battery configured to be removed from the top side of the cover;
a brush, wherein the brush is operatively connected to the first flange and the second flange, the brush configured to move linearly and in a horizontal direction along the first rail and the second rail;
a first motor and a second motor, the first motor located on a section of the first rail and operatively connected to a first belt system, wherein the first belt system moves the brush along the first rail and the second rail, and the second motor located on the first flange and operatively connected to the second belt system wherein the second belt system rotates the brush;
a first detector and a second detector, the first detector and the second detector positioned at locations on the first rail, the first detector and the second detector configured to stop the movement of the brush and reverse the direction in which the brush moves along the first rail and the second rail;
and
a remote control device, the remote control device configured to communicate with and operate the first motor and second motor.
