Abstract:
An apparatus for wiping a non-planar surface, the apparatus comprising:(a) a track arrangement including at least one track, said at least one track being taken to define a length of said track arrangement;(b) a drive wheel assembly including at least one motorized drive wheel, said drive wheel assembly engaging said track arrangement, and driving in alternate directions along the length of said track arrangement;(c) a wiper mechanically coupled to said drive wheel assembly such that movement of said drive wheel assembly along the length of said track arrangement draws said wiper across the surface; and(d) a motor operatively coupled to said drive wheel assembly for driving said at least one motorized drive wheel,wherein the length of said track defines a non-linear path parallel to a desired non-linear wiping path, and wherein said drive wheel assembly is configured such that continuous rotation of said motor in one direction generates alternating movement of said drive wheel assembly along said track arrangement so as to generate reciprocation of said wiper along said desired non-linear wiping path.
