Gantryless Car Wash Overhead Brush Support

The patent removes the floor-mounted gantry tracks from the system entirely. Instead of supporting the washing equipment on floor tracks, the system uses an overhead support structure with rails mounted on the ceiling or upper framework of the car wash building. This extraction of the tracks from the corrosive floor environment eliminates their exposure to water and chemical sprays, thereby reducing maintenance difficulty while preserving structural support functionality.

The patent introduces pivotal mounting for the top brush, allowing it to rotate and angle dynamically during the washing process. Instead of moving in a fixed vertical path, the pivoted brush can adjust its orientation to contact different portions of the vehicle surface. This dynamic capability enables effective washing with shorter gantry travel, as the brush can reach across the vehicle width by pivoting rather than requiring the gantry to traverse the entire length.

The patent divides the side brushing function into multiple segments by using four side brushes instead of two. These brushes are arranged to contact different portions of the vehicle - front sides, rear sides, and intermediate sections. This segmentation of the washing function across multiple brushes ensures comprehensive coverage of all vehicle surfaces, particularly improving contact at the front and rear surfaces that would be missed by only two brushes.

The patent inverts the traditional gantry configuration by moving the support structure from the floor level to the overhead ceiling area. Instead of a floor-mounted gantry that rises up and envelopes the vehicle from below, the system uses overhead rails that support the washing equipment from above. This inversion creates open space at floor level, allowing vehicle occupants to see out and reducing the claustrophobic effect, while the overhead structure still provides complete structural support and brush coverage.
