Floor treatment apparatus
View Patent ↗The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360° turns to facilitate the treatment of difficult to access portions of the floored surface.
1. A floor treatment apparatus, comprising:
a chassis having a front and a back and a lower surface, a front surface adjacent the front, a rear surface adjacent the back, a left side and right side and a platform;
at least a first wheel, a second wheel and a third wheel which at least partially support the weight of the chassis;
a floor treatment mechanism interconnected to the lower surface;
a power source interconnected to at least one of the wheels;
a mechanism operably interconnected to at least one of the wheels to allow an operator to steer the apparatus and wherein the chassis is allowed to rotate 360 degrees without substantially moving in other directions;
wherein the platform is located substantially below the steering mechanism and substantially directly above an axis extending between the center of the first and second wheels, which are located substantially toward the back of the apparatus; and
wherein the platform includes a throttle, an operator present switch that interrupts the throttle when not depressed, and a platform switch which must be engaged in order for the throttle to be effective.
2. The floor treatment apparatus of claim 1 , wherein the floor treatment mechanism is at least one of a brush, a burnisher, a squeegee, a vacuum and a debris collection device.
3. The floor treatment apparatus of claim 1 , wherein the chassis has a maximum outside envelope of about 50 inches high, 26 inches wide and 51 inches long.
4. The floor treatment apparatus of claim 1 , further including a debris collection device connected adjacent to the lower surface of the chassis.
5. The floor treatment apparatus of claim 1 , further including a fluid storage compartment, a chemical storage compartment and a control mechanism which will selectively mix fluid from the fluid storage compartment with fluid from the chemical storage compartment to form a cleaning fluid.
6. The floor treatment apparatus of claim 1 , further comprising:
an electric monowheel drive motor interconnected to the power source and at least one of the first wheel, the second wheel, and the third wheel.
7. The floor treatment apparatus of claim 6 , wherein the maximum vertical distance between the platform and the floor is 200 millimeters.
8. The floor treatment apparatus of claim 6 , wherein at least one of the first wheel and second wheel are independently driven by the drive motor.
9. The floor treatment apparatus of claim 6 , wherein the third wheel is a steered wheel driven by the drive motor.
10. The floor treatment apparatus of claim 6 , wherein the first wheel and second wheel are independently suspended.
