Abstract
Abstract In a car cleaning system for car washes having a car conveying device, a cleaning element which extends transversely to the direction of travel of the car. The cleaning element is held at its ends on a pair of lever arms which are swingable about a fixed swivel joint and can be changed in position in a manner corresponding to the contour of the car as viewed from the side of the car. The pair of lever arms is swingably guided in such a way that at the start of the cleaning process the lever arms are inclined obliquely downwardly in the direction opposite the direction of travel of the car and at the end of the cleaning process they are inclined obliquely downwardly in the same direction as the direction of travel of the car, terminating approximately in the region of the bottom of the car. The cleaning element is arranged for translation on the pair of lever arms, and is movable in such a manner that both at the beginning and at the end of the cleaning process it is at the lower end of the lever arms.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
212 words
A car cleaning apparatus, of the type where a car to be cleaned is conveyed in a path of travel of said car through the apparatus, comprising: a pair of lever arms having a lower end and an upper end, and being pivotally mounted adjacent the lower end; a cleaning element extending transverse to the path of travel of said car through the apparatus and being mounted moveably up and down said lever arms defining a travel path on said lever arms; said cleaning element being pivotally mounted with respect to said pair of lever arms; first means for moving said cleaning element from a lower end of said travel path of said lever arms at the beginning and end respectively of the cleaning process, second means for swinging said pair of lever arms to swing away from the car to a position extending obliquely downwardly opposite the direction of conveyance of the oncoming said car at the start of said cleaning process and to swing away from the car in a position extending obliquely downwardly to the same direction as the direction of conveyance of said car at the end of said cleaning process, respectively, and third means for pivoting said cleaning element with respect to said pair of lever arms.
Claim 2
Dependent Claim
212 words
A car cleaning apparatus, of the type where a car to be cleaned is conveyed in a path of travel of said car through the apparatus, comprising: a pair of lever arms having a lower end and an upper end, and being pivotally mounted adjacent the lower end; a cleaning element extending transverse to the path of travel of said car through the apparatus and being mounted moveably up and down said lever arms defining a travel path on said lever arms; said cleaning element being pivotally mounted with respect to said pair of lever arms; first means for moving said cleaning element from a lower end of said travel path of said lever arms at the beginning and end respectively of the cleaning process, second means for swinging said pair of lever arms to swing away from the car to a position extending obliquely downwardly opposite the direction of conveyance of the oncoming said car at the start of said cleaning process and to swing away from the car in a position extending obliquely downwardly to the same direction as the direction of conveyance of said car at the end of said cleaning process, respectively, and third means for pivoting said cleaning element with respect to said pair of lever arms.
Claim 3
Dependent Claim
62 words
The car cleaning apparatus according to claim 1, further comprising: a swivel joint located in the vicinity of a conveyance track-way of the apparatus, said pair of lever arms being pivotally mounted about said swivel joint; and each of said lever arms further comprising an upper free end, said free ends of said lever arms being operatively connected to form a portal.
Claim 4
Dependent Claim
