  FIG. 1 is a diagram showing an escalator 10 including a safety comb 100 according to the first embodiment of the present invention. The escalator 10 is a device that moves passengers between two floors with different heights. The escalator 10 includes a boarding board 6, a comb unit 8, a step 12, a moving handrail 14, and a balustrade 16.

  The boarding / alighting board 6 is a part for the passenger to temporarily stop to get into Step 12 or for the passenger to get off from Step 12. The comb portion 8 is attached to an end portion of the boarding / alighting plate 6 in order to prevent foreign matters and the like from easily entering the machine room. Step 12 is large enough to accommodate one or two passengers. The relationship between step 12 and the comb portion 8 in the vicinity of the boarding / exiting plate 6 will be described later.

  The moving handrail 14 is a portion where a passenger attaches or grabs a hand. Here, the moving handrail 14 is endless by joining both ends in the longitudinal direction. The balustrade 16 includes a moving handrail guide rail 15 and an inner plate 17. The moving handrail guide rail 15 has a function of guiding the moving handrail 14. The inner plate 17 is a side wall that stands on the side of the step 12.

  FIG. 2 is a plan view showing a positional relationship among the boarding / alighting plate 6, the comb unit 8, and the step 12. The comb portion 8 includes a comb main body portion 82 having a flat plate shape and a comb tip end portion 84. Further, a through hole 85 is formed in the comb main body 82.

  3 is a cross-sectional view taken along line AA in FIG. The boarding / alighting plate 6 includes a substrate portion 6b made of a metal material and a decorative portion 6a that covers the surface of the substrate portion 6b and is also made of a metal material. A screw hole 6 c is formed in the board portion 6 b of the boarding / alighting plate 6. The comb portion 8 is attached to the end portion of the boarding / alighting plate 6, and the comb portion 8 is fixed to the boarding / alighting plate 6 by tightening the screw member 86 with respect to the through hole 85 and the screw hole 6 c.

  FIG. 4 is a schematic diagram of a cross section taken along line BB in FIG. Cleats 120 are formed on the tread surface of step 12 to prevent passengers from slipping. The cleat 120 is formed in a convex shape at a predetermined interval along the longitudinal direction of the step 12. The comb tip 84 of the comb portion 8 is formed in a concave shape at a predetermined interval along the longitudinal direction of the step 12, and the cleat 120 and the comb tip 84 of the comb portion 8 are engaged with each other. When the escalator 10 is operating, the step 12 moves in the direction of arrow X (see FIGS. 2 and 3). At this time, in the gap 70 between the comb tip 84 of the comb portion 8 and the cleat 120, A safety comb 100 is formed.

  The safety comb 100 is a member that is filled over the entire gap 70 formed between the cleat 120 and the comb tip portion 84 of the comb portion 8. The safety comb 100 is formed of a resin member such as a urethane resin that is in a soft state and has an appropriate elasticity.

  Then, the manufacturing method and effect | action of the safety comb 100 which consists of the said structure are demonstrated using FIGS. FIG. 5 is a view showing the safety comb 100 before molding. FIG. 6 is a flowchart showing a procedure of a method for manufacturing the safety comb 100. As a procedure of the manufacturing method of the safety comb 100, as shown in FIG. 5, first, a soft urethane resin member in a required amount is joined to the comb tip 84 of the comb portion 8 in advance (S10).

  The comb portion 8 to which the urethane resin member is bonded is attached to the end portion of the passenger board 6 (S12). And the screw member 86 is fastened with respect to the through-hole 85 and the screw hole 6c, and the comb part 8 is fixed to the boarding board 6 (S14). As a result, the urethane resin member is positioned between the cleat 120 and the comb tip 84 of the comb portion 8. Next, the escalator 10 is operated, and step 12 is moved in the arrow X direction (S16).

  The urethane resin member joined to the comb tip 84 of the comb 8 is scraped by the cleat 120 (S18). Thus, the excess urethane resin member is scraped off, and the safety comb 100 that fills the gap 70 formed between the comb tip portion 84 of the comb portion 8 and the cleat 120 is molded. Thereby, it is possible to prevent foreign matters and the like from being caught in the gap 70 between the cleat 120 in step 12 and the comb tip 84 of the comb portion 8 with a simpler configuration.

  In addition to the manufacturing method described above, the safety comb 100 may operate the escalator 10 after placing a urethane resin member in a soft state along the longitudinal direction on the tread of one step 12 of the existing escalator 10. At this time, the urethane resin member in the soft state moves between the comb tip portion 84 of the comb portion 8 and the cleat 120 by the movement of step 12, and the excess urethane resin member is scraped by the cleat 120. The safety comb 100 can be similarly manufactured by this method.

  The safety comb 100 may be formed of, for example, a urethane resin member such as urethane rubber having an appropriate hardness in a rigid state instead of the urethane resin member in a flexible state having appropriate elasticity. At this time, the urethane resin member in a rigid state is joined to the comb tip portion 84 of the comb portion 8, the comb portion 8 is attached to the boarding board 6 by applying an appropriate pressing force, and the cleat 120 is moved when the step 12 moves. The safety comb 100 may be molded by cutting off excess urethane resin.

  In addition, even if it does not join the urethane resin member of a rigid state like urethane rubber to the comb front-end | tip part 84 of the comb part 8, the safety comb 100 which consists of a urethane resin member of the soft state manufactured by said manufacturing method is hardened. It may be changed to the safety comb 100 made of a rigid urethane resin member. The manufacturing method and operation of the safety comb 100 further including a curing step for changing such a urethane resin member from a soft state to a rigid state will be described with reference to FIGS.

  FIG. 7 is a view showing a flowchart in which the method of manufacturing the safety comb 100 further includes a thermosetting step. After finishing the procedures of S10 to S18 shown in FIG. 6, heating is performed so that the urethane resin member in the soft state is in an appropriate temperature state (S20). As a result, the urethane resin member in the soft state changes to a urethane resin member that is in a rigid state and has an appropriate hardness. For this reason, it can prevent that a foreign material etc. are pinched | interposed into the clearance gap 70 of the 1st cleat 120 of step 12 and the comb front-end | tip part 84 of the comb part 8 more suitably.

  FIG. 8 is a view showing a flowchart in which the method of manufacturing the safety comb 100 further includes a humidity curing step. After the procedures of S10 to S18 shown in FIG. 6 are finished, humidification is performed so that the urethane resin member in the soft state is in a proper moisture state (S30). Thereby, the urethane resin member in a soft state can be changed to a urethane resin member in a rigid state and having an appropriate hardness, and the same effect as the safety comb 100 can be obtained.

  FIG. 9 is a view showing a flowchart in which the method of manufacturing the safety comb 100 further includes an ultraviolet curing step. After the procedures of S10 to S18 shown in FIG. 6 are finished, an appropriate amount of ultraviolet rays is irradiated to the flexible urethane resin member (S40). Thereby, the urethane resin member in a soft state can be changed to a urethane resin member in a rigid state and having an appropriate hardness, and the same effect as the safety comb 100 can be obtained.

  In the above description, the soft member is a resin member, but may be a putty member mixed with resin. In the above description, the resin member is a urethane resin member. However, the resin member may be a resin member other than a urethane resin, such as an epoxy resin, a phenol resin, a melamine resin, a urea resin, an unsaturated polyester resin, or an alkyd resin. There may be.

  In the above, the curing step for changing from the soft state to the rigid state may be performed using a so-called two-component curing method in which a mixture of the resin member and the curing agent is cured.
