Abstract

A floor surface maintenance vehicle, and methods of using a floor surface maintenance vehicle, the vehicle including a frame, a plurality of wheels, a cleaning component extending from an underside of the frame, a steering wheel having a central aperture and rotatable about a central axis, and a steering wheel hub located within the central aperture of the steering wheel and having a panel, wherein the panel is stationary relative to the central axis. Buttons are provided on the panel, including a first button that is C-shaped and extends around a portion of a periphery of the panel. The C-shaped button may be used to control frequently used functions such as cleaning functions or operation of a horn, for example.

Claims

1. A floor surface maintenance vehicle comprising:

a frame;

a plurality of wheels;

a cleaning component extending from an underside of the frame;

a steering wheel having an outer ring, and a central aperture connected concentrically to a steering shaft and rotatable about a central axis;

a steering wheel hub located within the central aperture of the steering wheel and having a panel, wherein the panel is stationary relative to the central axis;

a first button provided on the panel, the first button is C-shaped and extends around a portion of a periphery of the panel, the first button being stationary with respect to the central axis of the hub, the first button being disposed at a distance from the outer ring of the steering wheel such that the first button is actuable by an operator'"'"'s fingers when the operator'"'"'s fingers moves with respect to the stationary central axis when turning the steering wheel, the first button controls a cleaning operation of the vehicle.

2. The floor surface maintenance vehicle of claim 1 wherein the first button occupies an arc of about 30 to about 90 degrees of a circumference of the periphery of the panel.

3. The floor surface maintenance vehicle of claim 2 further comprising a second button on the panel, wherein the second button occupies an arc of about 30 to about 90 degrees of a circumference of the periphery of the panel, wherein the second button controls a cleaning operation of the vehicle.

4. The floor surface maintenance vehicle of claim 3 wherein the first and second buttons each control the same cleaning function.

5. The floor surface maintenance vehicle of claim 4 wherein the first and second buttons each turn on and turn off a flow of a fluid from a fluid tank.

6. The floor surface maintenance vehicle of claim 5 wherein the first and second buttons are located at mirror image locations on opposite sides of the panel.

7. The floor surface maintenance vehicle of claim 3 wherein the first button moves a hopper up, and the second button moves the hopper down.

8. The floor surface maintenance vehicle of claim 1 wherein the first button is located in approximately one half of the circumference of the panel.

9. The floor surface maintenance vehicle of claim 8 wherein the first button controls a horn.

10. The floor surface maintenance machine of claim 8 wherein the first button is located on a top half of the panel.

11. The floor surface maintenance machine of claim 1 wherein the first button is located in approximately one half of the circumference of the periphery of the panel, further comprising a second and a third button, wherein each of the second and third buttons are C-shaped, extend around a portion of the periphery of the panel, and occupy between about one eighth to about one quarter of the circumference of the periphery of the panel.

12. The floor surface maintenance machine of claim 11 wherein the first button is a horn and the second and third buttons control a flow of fluid from the fluid tank.

13. The floor surface maintenance machine of claim 11 wherein the first button is a horn, the second button moves a hopper up, and the third button moves the hopper down.

14. The floor surface maintenance machine of claim 1 further comprising:

a second button located on the panel in a location which is more centrally located than the first button, wherein the second button controls a cleaning function of the vehicle; and

an indicator light located in proximity to the second button which is illuminated when the function of the second button has been activated.

15. A floor surface maintenance vehicle comprising:

a frame;

a plurality of wheels,

a fluid tank;

a cleaning component extending from an underside of the frame;

a steering wheel having a central aperture connected concentrically to a steering shaft and rotatable about a central axis;

a steering wheel hub located within the central aperture of the steering wheel and having a panel, wherein the panel is stationary relative to the central axis;

a first button provided on the panel for controlling a cleaning function of the vehicle, the first button is C-shaped and extends around a portion of a periphery of the panel; and

a second button provided on the panel for controlling a horn, the second button is C-shaped and extends around a portion of a periphery of the panel, the first button occupying an arc of about greater than 90 degrees of a circumference of the periphery of the panel, the first and second buttons each being stationary with respect to the central axis of the hub, the first and second buttons being disposed at a distance from the outer ring of the steering wheel such that the first and second buttons is actuable by an operator'"'"'s fingers when the operator'"'"'s fingers moves with respect to the stationary central axis when turning the steering wheel.

16. The floor surface maintenance vehicle of claim 15 wherein the first C-shaped button starts and stops a flow of fluid from the fluid tank.

17. The floor surface maintenance vehicle of claim 16 further comprising one or more buttons to increase or decrease the rate of flow of fluid from the fluid tank.

18. The floor surface maintenance vehicle of claim 15 wherein the first C-shaped button raises a hopper.

19. A method cleaning a floor comprising:

activating a floor surface maintenance vehicle, the floor surface maintenance vehicle comprising;

a frame;

a plurality of wheels;

a fluid tank for storing a fluid;

a cleaning component extending from an underside of the frame;

a steering wheel having a central aperture connected concentrically to a steering shaft and rotatable about a central axis;

a steering wheel hub located within the central aperture of the steering wheel and having a panel, wherein the panel is stationary relative to the central axis;

a first button provided on the panel, wherein the first button is C-shaped and extends around a portion of a periphery of the panel, the first button being stationary with respect to the central axis of the hub, the first button being disposed at a distance from the outer ring of the steering wheel;

driving the floor surface maintenance vehicle over the floor to be cleaned; and

pressing the first button with an operator'"'"'s fingers when moving the operator'"'"'s fingers with respect to the stationary central axis when turning the steering wheel to control a cleaning function of the vehicle while steering the vehicle.
