Abstract:
1. An apparatus for cleaning steps of an escalator, each of the escalator steps having a plurality of parallel tread ridges separated by tread grooves, the escalator having parallel opposing rail housings for guiding steps of the escalator, the apparatus comprising: a cleaning pad assembly configured to extend substantially perpendicular to direction of motion of the escalator steps, said cleaning pad assembly comprising a bottom pad having a cleaning contact surface, said contact surface carrying a plurality of spaced parallel pad ridges separated by pad grooves, said plurality of pad ridges being configured to frictionally matingly engage within the tread grooves while contacting bottoms and sides of the tread grooves, and said plurality of pad grooves being disposed to matingly frictionally receive tread ridges therein, a pitch of the pad ridges and pad grooves matching a pitch of the tread ridges and tread grooves said cleaning pad assembly further comprising a telescopically-extendable means for selectively mounting the cleaning pad assembly between the rail housings of the escalator, wherein said means for selectively mounting the cleaning pad assembly between the rail housings of the escalator comprises spaced apart toggle clamps secured to the upper plate, each of said toggle clamps having telescopically extendable rods movable between a retracted position and an extended position, said rods being configured to support the cleaning pad assembly between the rail housings of the escalator.
