摘要： PROBLEM TO BE SOLVED: To prevent dust from being scattered in a machine chamber or being accumulated in the middle part of the machine chamber by arranging partition plates, which are brought into contact or non-contact with a footstep, in the front and in the back of a cleaning brush in the moving direction of the footstep in addition to the cleaning brush. SOLUTION: In the moving direction of a footstep 7, partition plates 16 are arranged in the front and the back of a cleaning brush 12. When an escalator is operated upward, the footstep 7 is moved toward the left and dust adhering to the footstep 7 is removed by means of the partition plate 16 so as to be scattered backward, however, the dust is not moved backward but accumulated in a part λ between the both partition plates 16 as the cleaning brush 12 is brought into contact with the footstep 7. When the escalator is operated downward, the footstep 7 is moved toward the right and dust adhering to the foot step 7 is removed by means of the partition plate 16 so as to be scattered backward, however, the dust is not moved backward but accumulated in a part &Ogr; between the both partition plates 16 as the cleaning brush 12 is brought into contact with the footstep 7. The partition plates 16 are brought close to the footstep 7 as much as possible if they are made of nonmetallic material, while a clearance (e) is arranged between the footstep 7 and the partition plates 7 if they are made of metallic material.

摘要： PURPOSE:To transport a large amount of personnel efficiently by providing stations where vehicles are stopped in association with vertical movement of the vehicle so as to allow passengers to get in and out, in a passenger transporting facility for transporting a large member of passengers up and down. CONSTITUTION:When passengers go to an underground space 2 from a ground surface 1, for example, they get in a vacant vehicle 17A from the upper stage of an upper station 7 or from the entrance 11 of a lower platform and, at the same time, getting in and out from the vehicle 17A is also made at the lower station 8 and these vehicles are in standby condition. When elevating frames 15A and 15B holding another vehicle 17B are raised and lowered in an elevating path 6 and seated on a floor, the vehicle 17B is moved to the opposite side to the upper station 7. After the movement is completed, the vehicle 17A in standby condition is moved into the elevating frame 15A through a moving path and, after getting in of the vehicle 17B(17a) to the elevating frames 15A and 15B is completed at the upper and lower ends of the elevating path 6, these frames are raised and lowered to transport the passengers. Thus, a large amount of personnel can be transported efficiently.

摘要： PROBLEM TO BE SOLVED: To prevent a damage such as lowering of elevating performance, breakage of a passenger conveyor even when bristles of a cleaning brush are caught in a clearance of a footstep. SOLUTION: This device is constituted of a cleaning brush 4 furnished with bristles 6 to clean foreign matter stuck on a tread 2 of a passenger conveyor and a holding means of the bristles and a fixing means 5 to support and fix the cleaning brush 4. In this case, the holding means to hold the bristles is constituted of a hole part provided on the cleaning brush 4 and a core wire for bristle holding provided on a hole part bottom part, a plural number of the bristles 6 are folded back by the core wire for bristle holding, and it is constituted to make only one end of a plural number of the bristles 6 drawn out of the hole part which is longer than the other end make contact with the tread 2. When the bristles 6 are caught between footsteps 1, holding force of the holding means becomes smaller than force to pull the bristles 6 by movement of the footsteps 1, only the bristles 6 are removed from the cleaning brush 4 and removal of the cleaning brush 4 itself is prevented.

摘要： PROBLEM TO BE SOLVED: To effectively increases the temperature of the whole of a comb by a method wherein a heat generating body is mounted directly in an arbitrary position below the comb formed of a material having excellent thermal conductivity. SOLUTION: A comb 2 to comb the uneven surface of a step 1 is formed of a metallic material having excellent thermal conductivity to transmit the heat of a heat generating body 5 to the tip and the surface of the comb. The heat generating body 5 is a sheath heater closed in a metallic pipe and by adjusting length to a value approximately equal to the overall width of a plurality of the arranging comb 2, the temperatures of the combs 2 are simultaneously increased. Since a groove in which the comb 2 is inserted makes contact with the heat generating body 2, outer shapes are the same as each other and formed approximately a U-shape and arranged in an arbitrary position. A heat insulation material 7 prevents emission of the heat of the comb 2, heated by the heat generating body 5, to the base plate 3 side. A thin substance, such as glass fibers, is used and has approximately the same size as that of the mating surfaces of the comb 2 and a base plate 3 and a plurality of through- holes through which a fixing tool 9 and an elastic substance are extended are formed. The heat generating body 5 is pushed up by an elastic body having size lower than a groove width and a press plate and makes reliable contact with the comb 2.

摘要： PROBLEM TO BE SOLVED: To prevent impact with a footboard from occurring even when lifting force acts on a cleaning brush by installing a means to regulate displacement of this brush to the tread side. SOLUTION: A tread cleaning device 8 is equipped with a means to regulate any displacement of a cleaning brush 11 to the side of a footboard 3. This displacement regulating means is composed of a crossbeam 14B of a main frame being situated at the side of the cleaning brush 11 of an arm 9 and a stopper 15 locked to the arm 9 in opposition to this crossbeam 14B. In addition, the stopper 15 comes close to the crossbeam 14B with a gap (g) which is set to be smaller than a space (h) between the upper end of a support fitting and the return side footboard 3. Supposing that the cleaning brush 11 is hitched on the footboard 3, a tip of the arm 9 is uplifted by moving force of the footboard 3 via the cleaning brush 11, but since the stopper 15 hits first on the crossbeam 14B, any possible uplift more than it is prevented. In brief, any displacement of the cleaning brush is checked, thereby preventing any collision of the arm 9 with the footboard 3.

摘要： PROBLEM TO BE SOLVED: To permit passengers to get on and off on the way without need for a wide area by forming a plurality of electrically-driven roads continuously upwards at intervals from the ground, forming an opening at a passage, and communicating the opening with a section above the ground through a communicating passage. SOLUTION: Where passenger transport equipment with electrically-driven roads is constituted utilizing the upper space of an ordinary road which is adjacent to a driveway and involves a sidewalk 2, a supporting frame 4 is supported through a plurality of columns along the direction of the sidewalk 2, and electrically-driven roads 5A and 6A whose traveling directions are opposite to each other are formed in parallel at the supporting frame 4. The electrically-driven roads 5A, 6A are formed continuously through a road 4A, and passengers are capable of making connection with a plurality of electrically- driven roads 5A, 6A for traveling. At the passage 4A for connection, an opening passing through the supporting frame 4 vertically is formed, and at a communicating passage formed so as to cross the sidewalk 2 from the opening, escalators 7A, 7B are installed along the transferring direction.

摘要： PROBLEM TO BE SOLVED: To shorten the operation time for adjustment set by adjusting the position of a guide pin also serving as a spring bearer, which is screw-engaged with a bracket provided on a base to continuously adjust pressing, and attaching and detaching only a pressing ring to attach and detach a handrail belt. SOLUTION: As the driving force is substantially proportional to the pressing force, the driving force is determined by the compression amount of a spring 22. A lock nut 21 is loosened to turn a guide pin 20 and move the spring 22 up and down, thereby setting the spring 22, and the guide pin 20 is fixed by the lock nut 21. A lock nut 25 is loosened and a pull bolt 24 is rotated to be screwed in a bracket 26, and a frame 17 is lowered by several millmeters against the spring 22. Subsequently, a nut 29 is removed to remove a pressing ring 11 from the frame 17. Thus, a gap larger than the thickness of a handrail belt 3 is produced between a driving wheel 10 and the frame 17, so that the handrail belt is removed to this side by the gap.
