TECHNICAL FIELB

|§0d2J The present disclosure relates generally to a rotary brash apparatus for a vehicle wash. More specifically, the present disclosure relates to a pad element for a rotary brash apparatus that provides improved cleaning capabilities for a vehicle exterior.

BACKGROUND FOR THE INVENTION

|§0 I31 Rotary brash apparatuses are frequently used in vehicle washes or vehicle wash systems for contacting, scrubbing, and cleaning exteriors of vehicles. These brushes typically include a rotary hub portion with an axis of rotation that is oriented parallel to a vehicle exterior and includes a plurality of media elements that are coupled to the hub portion, which are intended to engage the vehicle. As the rotary hub is driven about its axis of rotation, the plurality of media elements blossom generally outward (perpendicular with respect to the axis of rotation) due, in part, to centrifugal force, so that they can contact a vehicle exterior to remove dirt and debris and effectuate cleaning. To apply increased scrubbing and cleaning, the rotary hub can be rotated faster to increase the speed at which the media elements contact the vehicle exterior. This generally creates an increased slapping noise due to an increased force of contact between the media elements and the vehicle exterior, which can make the car wash experience unenjoyable for a user. Also, as the speed of the brush increases, the perception of potential damage to the vehicle exterior increases. |0 §41 These rotary brash apparatus are configured such thai the media elements are oriented generally perpendicular to the brash axis of rotation during use. As such, as the rotary hub is driven, the media elements only contact the vehicle exterior in a single direction, which limits fee cleaning capabilities of the media elements and thus the effectiveness of the wash process. For example, with respect to a conventional side brush apparatus, as the hub rotates, the media elements are configured to contact a side exterior surface of the vehicle in only one direction, i.e., a front to back direction. In other words, the media elements contact a forward part of the exterior surface and move backward along the vehicle exterior before losing contact therewith. As such, any force applied to fee vehicle exterior to remove dirt and debris is applied on only a single direction.

|§CM)5J While rotary brushes having an axis of rotation which is oriented generally perpendicular to a vehicle exterior are also known, these brushes are only used to clean vehicle wheels as they employ hard or rigid media elements, such as synthetic bristles. As the bristles will mar a painted surface, they are not suitable for cleaning or treating a vehicle exterior. Moreover, these rotary brush assemblies also include a rigid hub or backing portion. Thus, if the media elements secured to these rigid structures encounter angled or curved exterior vehicle surfaces, die brash assemblies cannot accommodate these variations and thus are not suitable for use for cleaning a vehicle exterior for this additional reason.

|00061 ft would therefore be desirable to provide a rotary brush apparatus that yields improvements over these deficiencies.

SUMMARY OF THE INVENTION

i§0 71 It is therefore an aspect of the present disclosure to provide a rotary brash apparatus for a vehicle wash system that can provide improved cleaning of a vehicle exterior surface. |000S| ίί is another aspect of the present disclosure to provide a rotary brush apparatus for a vehicle wash system that more effectively cleans contoured surfaces, comers and/or complex surfaces of a vehicle exterior.

P0§9J It is still another aspect of the present disclosure to provide a rotary brush apparatus for a vehicle wash system that provides improved cleaning of a vehicle exterior without marring or scratching of the vehicle exterior.

fOOlOf It is still a farther aspect of the present disclosure to provide a rotary brush apparatus for a vehicle wash system that provides improved cleaning of a vehicle exterior by way of multi-directional contact between the brush media elements and the vehicle exterior. [ΘΘ11] In accordance with the above and the other aspects 3 a component for a vehicle wash system is provided. The component includes a rotatable stem portion and a backing member in communication with the rotatable stem portion. The backing member is configured to rotate with the stem portion about an axis of rotation defined by the centerline of the stem portion, A plurality of media elements are secured to the backing member with the plurality of media elements being constructed of a generally self-supporting and flexible material arid wherein the plurality of media elements are oriented generally perpendicular to the hacking member. The plurality of media elements are configured to rotate in a working plane defined by the backing member and the working plane is oriented generally perpendicularly to the axis of rotation. Additionally^ the plurality of media elements are configured during a wash process to contact at least an exterior painted surface of a vehicle to effectuate cleaning thereof.
