In FIG. 1 to FIG. 3, a passenger board tread cleaning device 1 is installed so as to extend in a substantially horizontal direction when in use, and a housing 2 is endless, such as an escalator, by an attachment arm 3 as shown in FIG. 4. It installs on the tread 11 connected in the shape. Inside the housing 2 are a drive motor 6 having a drive shaft 6a, and a tread 12 that is disposed endlessly and disposed on both ends in the longitudinal direction of the tread 12 and the center between the two ends. A brush device 5 for cleaning the upper surface portion of the tread plate 11 by bringing a rotating brush into contact with the upper surface portion, a rotating shaft 7 to which the brush devices 5 on both ends in the longitudinal direction of the tread plate 11 are attached, and the tread plate 11 A rotating shaft 8 to which a brush device 5 on the central portion side between both ends in the longitudinal direction is attached, a driving belt 9 suspended on a driving shaft 6a and a rotating shaft 7 of the driving motor 6, and a driving motor Drive belts 10 suspended on the drive shaft 6a and the rotary shaft 8, and dust attached to the brush devices 5 disposed in contact with the brush devices 5, respectively. Dust collecting body 4a having a dust collecting body 4a And a means 4. The rotating shaft 7 and the rotating shaft 8 are engaged with holes provided in the side plate of the housing 2 and are rotatably held. Moreover, although not shown in figure, the dust collection | recovery means 4 is hold | maintained in the state pressed against the brush apparatus 5 with the predetermined pressure by the fixing component.

  As shown in FIG. 6B, the brush device 5 has a substantially cylindrical appearance with a linear body 5a such as many brushes radially planted around a holding body 5b connected and fixed to the rotary shaft 7. It is formed in accordance with the rotation of the drive motor 6, and the tip of the linear body 5a abuts so as to enter the groove of the tread plate 11 of the passenger conveyor such as an escalator, It is configured to scrape dirt and foreign matter adhering to the upper surface of the tread board 11.

  In the first embodiment, as shown in FIG. 1, one brush device 5 is provided on each of both ends in the longitudinal direction of the tread plate 11 and one on the center side, and one brush device 5 is provided on each side of the both ends. One of the side portions is configured to be able to be cleaned at once over the entire longitudinal direction of the tread board 11 by overlapping each other in the longitudinal direction of the tread board 11.

  The dust collecting means 4 includes a dust collecting body 4a made of a fibrous material made of a material such as natural fiber or chemical fiber, or a foamed material block, and a dust collecting body 4a. It is comprised from the support plate 4b which hold | maintains.

  When the treadle cleaning device 1 is fixed to the skirt 13 or the like near the entrance 14 of the passenger conveyor by the mounting arm 3, the top of the tread 11 and the tread 11 not shown are shown in FIG. It is comprised so that the front-end | tip part of the linear body 5a of the brush apparatus 5 may contact | abut in a groove | channel. In FIG. 4, the handrail 12 and the skirt portion 13 on the front side of the paper are omitted for the purpose of explaining the installation state of the apparatus.

  Next, the operation of the first embodiment configured as described above will be described. First, the tread board cleaning device 1 is set in the vicinity of the passenger entrance 14 of the passenger conveyor so that the outer peripheral surface of the brush device 5 is pressed onto the tread board 11 as shown in FIG.
