Appl. No.:

09/849763

Assignee:

Mark VII Equipment LLC - Arvada CO

International Classification:

B08B 302

US Classification:

134123, 134198, 134181

Abstract:

An automatic vehicle washing system is described. The vehicle washing system incorporates an elongated overhead cleaning platform for cleaning the front, top and rear surfaces of a vehicle. The overhead cleaning platform is attached to a single lift mechanism at a first end and is suspended from a belt at a second end, wherein the belt is also operatively connected to the first end. Accordingly, vertical movement of the lift actuator causes both ends of the platform to uniformly rise or descend. The platform further comprises a pivotal boom with fluid nozzles attached thereto, and a reciprocating pivotal actuator. The reciprocating pivotal actuator is capable of pivotal movement to any number of angular orientations within its operative range of motion. Advantageously, the pivotal and vertical positions of the nozzles can be independently varied, permitting the location of the overhead cleaning nozzles to be optimized for various vehicle profiles.

International Classification:

B08B 3/02

US Classification:

134123, 134198, 239240

Abstract:

Rotating turbo nozzles for use in car wash systems have a nozzle body with a hollow interior in which a nozzle member is rotated in unison with a fluid vortex created by pressurized fluid introduced into the interior of the nozzle body through passageways forming an acute angle with the hollow interior. Systems are employed for reducing the speed of rotation of the nozzle member relative to the nozzle body so as to improve the effective range in which the nozzle body can emit cleaning fluids with an acceptable impact force.

International Classification:

US Classification:

134 18, 134 32, 134 56 R, 134123, 134172

Abstract:

In an automatic wash, a control unit operates a boom arm around a vehicle in a bay by moving a bridge along a lengthwise vehicle orientation, moving a trolley on the bridge along a widthwise vehicle orientation, and rotating the boom arm about the trolley. The boom arm is coupled to a mount which is flexibly coupled to the trolley such that boom arm impact displaces the mount and the trolley. The displacement may be two-dimensional and/or angular. In response, the control unit determines whether an impact has occurred by comparing the data to a baseline. If there is an impact, the control unit relocates the boom arm and may continue the wash process. If a sufficient force impact occurs that the control unit cannot correct, the boom arm may disengage from the mount which may trigger a breakaway sensor and cause the control unit to abandon the wash.

US Classification:

134123, 134172, 134198

Abstract:

An apparatus for washing a vehicle that is relatively moved through the apparatus includes pivotal side arms with independently pivotal nozzles for the dispensing of cleansing fluids as well as a pivotal overhead boom that also includes independently pivotal nozzles so that the side arms and the boom as well as the nozzles associated therewith can be optimally positioned for directing high pressure liquid at the vehicle. The side arms and boom are also moved from retracted to extended positions with power cylinders and retracted from the extended to retracted positions by counter balancing weights.
