Definitions

  • This invention relates generally to cleaning apparatus. More specifically, this invention relates to cleaning apparatus for cleaning escalators and travellators.
  • Escalators and travellators are generally in regular use and the requirement to keep them clean coupled with the need to minimise downtime presents a challenge.
  • Known escalator cleaning machines tend to be large, complex and expensive making them suitable for large shopping centres or airports but not for smaller buildings. Further, known machines may be effective at cleaning the step plate of an escalator or travellator step but are less so when it comes to cleaning the intermeshing portions between steps.
  • US2015/259178 discloses a cleaning pad which has a plurality of ridges and grooves configured to mesh with the channels and ribs of an escalator or moving walkway step.
  • the invention provides an escalator cleaning apparatus according to claim 1.
  • the castellated side acts in concert with the brush element to engage both the grooves of the step plate and the gap between intermeshing portions of adjacent steps. More specifically, the position of the brush element along the edge of the cleaning head enables a user to engage the cleaning head along the exposed castellated surface of one of the steps or risers all the way to its interface with an adjacent step, at which point the brush element is urged into the gap to ensure that it is cleaned thoroughly, without the need for suction or a further cleaning tool.
  • the leading or trailing edge, or a leading side or trailing side of the cleaning head may be slanted or have an acclivity, a gradient, a ramp or an incline.
  • the leading or trailing edge or side may form an angle, for example an oblique, acute or obtuse angle, between the first side and a second side.
  • the brush element may be mounted to or relative to, a leading side or trailing side of the cleaning head, for example such that the leading side or trailing side provides a bracing surface or abutment surface for the brush element. Forming the leading side or trailing side as a slanted bracing surface ensures that the brush element is maintained in a configuration in which it is urged into the gap.
  • the cleaning apparatus may comprise a cleaning cover, which may be removable.
  • the cleaning cover may be arranged to cover or at least partially cover, enclose or hide the first side.
  • the cleaning cover may be flexible, for example such that, in use, it engages, follows the contours of or substantially cooperates with the first side or castellations thereof.

  • the cleaning apparatus may be configured such that the cleaning head forces, in use, the cleaning cover into the grooves of an escalator or travellator step.
  • the cleaning cover may be configured to provide protection to the first side of the cleaning head, e.g. prolonging its useful life.
  • the cleaning cover may also be disposable, for example such that once it is dirty, soiled or ingrained it can be disposed of and/or replaced.
  • the cleaning apparatus may comprise two or more, e.g. a plurality of, different cleaning covers. At least two of the cleaning covers may comprise different materials or configurations, such as different piles, e.g. deep or shallow piles.
  • the cleaning cover may comprise or be constructed of an absorbent material, stretch fit fabric or cloth.
  • the cleaning cover may be impregnated with a cleaning medium or detergent.
  • the cleaning apparatus may comprise a reservoir and/or a dosing means, which may be operatively or fluidly connected to the reservoir, for introducing the or a cleaning medium or detergent to the cleaning cover.
  • the cleaning apparatus may comprise an attachment or engaging or securing means, for example a clamp, such as a clamping element, member or portion.
  • the clamp may be connected to the cleaning head and/or be movable between a first position, e.g. a spaced or loading position, and a second position, e.g. a clamping or use position.
  • the clamp may be spaced from the cleaning head in the first position, for example such that a gap is formed between the clamp and the cleaning head.
  • the clamp may retain, hold or clamp, for example by clamping force, the or a cleaning cover in the second position, e.g. against the cleaning head.
  • the cleaning apparatus may comprise another attachment or engaging or securing means.
  • the cleaning apparatus may comprise an aperture with projections, e.g. for engaging the cleaning cover.
