Vehicle wash system having a vertically operated top brush with pivoting ability

1. A vehicle washing system comprising:

a frame disposed above a vehicle treatment area and configured for supporting at least one vehicle treatment component;

a first brush coupled to the frame, wherein the first brush is rotatable about a central axis which axis is oriented generally parallel to the vehicle treatment area;

a vertical translation mechanism operatively coupled to the first brush, wherein the vertical translation mechanism permits movement of the first brush in a vertical direction relative to the vehicle treatment area for contacting at least an upper surface of a vehicle disposed therein; and

a pivot mechanism operatively coupled to the first brush, wherein the pivot mechanism permits pivoting movement of the first brush about a pivot point in a direction toward and away from a vehicle entrance portion;

wherein the vertical translation mechanism includes a scissor support mechanism and includes the pivot point of the pivot mechanism, and the scissor support mechanism is pivotable about the pivot point, wherein the pivot point is disposed at an upper end of the scissor support mechanism, wherein the first brush is disposed at a lower end of the scissor support mechanism, and wherein the first brush pivots about the pivot point when the scissor support mechanism pivots about the pivot point.

2. The system of claim 1 , wherein the vertical translation mechanism comprises the scissor support mechanism, the scissor support mechanism extending between the frame and the first brush, wherein the scissor mechanism includes a retracted position and an extended position, wherein the first brush is disposed closer to the vehicle treatment area in the extended position relative to the retracted position.

3. The system of claim 1 , wherein the vertical translation mechanism is coupled to a pivot frame, and the pivot frame includes the pivot point of the pivot mechanism.

4. The system of claim 1 , wherein the vertical translation mechanism operates without a guidetrack, wherein when the vertical translation mechanism is in the retracted mechanism there are no downwardly hanging guides extending below the vertical translation mechanism.

5. The system of claim 1 , wherein the frame is moveable horizontally relative to the vehicle treatment area, such that the system may operate with the vehicle in a fixed position in the vehicle treatment area.

6. The system of claim 5 , wherein the frame is supported by horizontally extending rails.

7. The system of claim 1 , wherein the frame is horizontally fixed relative to the vehicle treatment area, such that the system may operate with the vehicle traveling horizontally through the vehicle treatment area.

8. The system of claim 1 , further comprising:

a controller having a processor configured to receive signals from the washing system regarding an operating state of the system and further configured to send signals to the brush to effect vertical translation thereof.

9. A method for treating a vehicle body in a vehicle washing system, the method comprising:

providing a vehicle having a vehicle body within a vehicle treatment area of a vehicle washing system, wherein the vehicle washing system comprises:

a frame disposed adjacent the vehicle treatment area;

a rotating brush secured to the frame and configured to contact at least an upper surface of a vehicle, the rotating first brush including a plurality of wash media elements;

a brush translation mechanism in communication with the rotating brush and configured to move the rotating brush upwardly and downwardly with respect to the vehicle treatment area between an extended position and a retracted position; and

a pivot mechanism coupling the brush translation mechanism to the frame such that the rotating brush may pivot forwardly and rearwardly in response to contact with a vehicle exterior;

wherein the pivot mechanism includes a pivot point that is vertically fixed with respect to the vehicle treatment area and the brush translation mechanism pivots about the pivot point;

moving the rotating brush in a downward vertical direction relative to the vehicle body;

pivoting the rotating brush about the pivot point disposed above the vehicle body;

moving the rotating brush in a horizontal direction relative to the vehicle body; and

moving the rotating brush in an upward vertical direction relative to the vehicle body.

10. The method of claim 9 , further comprising:

detecting, with a controller, a contour of the vehicle body; and

determining a degree of downward vertical movement of the rotating brush in response to the detection of the contour of the vehicle body;

wherein the step of moving the rotating brush in a downward vertical direction is performed in response to determining the degree of downward vertical movement.

11. The method of claim 9 , wherein the rotating brush is secured to the frame and remains generally horizontally fixed relative to the vehicle treatment area, and the vehicle moves horizontally along the vehicle treatment area.

12. The method of claim 9 , wherein the vehicle remains horizontally fixed relative to the vehicle treatment area, and the rotating brush moves horizontally along the vehicle treatment area.

13. The method of claim 9 , wherein the step of moving the rotating brush in a downward vertical direction includes extending the brush translation mechanism.

14. The method of claim 9 , wherein the step of moving the rotating brush in an upward vertical direction includes retracting the brush translation mechanism.

15. The method of claim 9 , wherein the step of pivoting the rotating brush includes pivoting the brush translation mechanism about the pivot point.

16. A vehicle wash system, comprising:

a frame disposed adjacent a vehicle treatment area;

a rotating brush secured to the frame and configured to contact at least an upper surface of a vehicle, the rotating brush including a plurality of wash media elements;

a brush translation mechanism in communication with the rotating brush and configured to move the rotating brush upwardly and downwardly with respect to the vehicle treatment area between an extended position and a retracted position; and

a pivot mechanism coupling the brush translation mechanism to the frame such that the rotating brush may pivot forwardly and rearwardly in response to contact with a vehicle exterior;

wherein the pivot mechanism includes a pivot point that is vertically fixed with respect to the vehicle treatment area and the brush translation mechanism pivots about the pivot point.

17. The vehicle wash system of claim 16 wherein the brush translation mechanism comprises a scissor support mechanism that extends between the frame and the rotating brush.

18. The vehicle wash system of claim 16 , wherein the frame is stationary with respect to the vehicle treatment area.

19. The vehicle wash system of claim 16 , wherein the frame moves with respect to a vehicle disposed in the vehicle treatment area.

20. The vehicle wash system of claim 16 , further comprising:

a controller having a processor configured to receive signals from the washing system regarding an operating state of the system and further configured to send signals to the brush to effect vertical translation thereof.
