Abstract
A sweeping unit for a sweeping machine to clean a floor area, has a driven pair of closed loop sweeping belts for engaging the floor, the driven sweeping belts including a first portion fixed in position relative to a mounting platform and a second movable portion. First rollers constrain the first portions of the driven sweeping belts relative to the mounting platform, and second guide rollers, which are movable relative to the mounting platform, constrain the second portions of the belts, respectively. The width of the floor area that is swept when the sweeping machine moves in a working direction, is variable as the second guide rollers are moved manually or automatically. The sweeping unit may be combined with a scrubber device having similar width adjustment features.
Claims15
A sweeping unit for use with a sweeping machine to clean a floor area when said sweeping unit moves in a working direction, the sweeping unit comprising:
- a mounting platform;
- driven sweeping means for engaging said floor area, said driven sweeping means including a first portion and a second portion;
- first guide means for constraining said driven sweeping means relative to said mounting platform, said guide means including first guide elements positioned at fixed locations on said mounting platform, and a second guide element which is movable relative to said mounting platform generally in a plane,
- said first portion of said driven sweeping means being constrained to a fixed path relative to said platform by said first guide elements, said second portion of said driven sweeping means being constrained by said second guide element to movement generally in said plane,
- a distance between a fixed line oriented in said working direction on said platform and said second guide element being varied as said second guide element is moved, whereby a width of said floor area that is swept when said sweeping machine moves in said working direction, is variable;
- and
- means for movably mounting said second guide element relative to said platform.
