[0052] Implementation method 1.

[0053] The structure of the passenger conveyor 1a in Embodiment 1 will be described. Figure 1 1a is a diagram showing a passenger conveyor 1a. Figure 1 In the figure, the passenger conveyor 1a is installed across the lower floor 2a and the upper floor 2b of the building. In addition, the passenger conveyor 1a is formed with an end post 8, a straight part 9, a curved part 10, a straight part 9, a curved part 10, a straight part 9, and an end post 8 from the lower floor 2a toward the upper floor 2b. Hereinafter, the end post 8 and the curved part 10 are referred to as a curved section 40.

[0054] exist Figure 1 In the figure, the passenger conveyor 1a comprises: a truss 3; a plurality of steps 4, which are supported by the truss 3 and connected in a ring shape; a pair of handrails 5, which are arranged on the truss 3 and are arranged on both sides of the width direction of the steps 4 along the moving direction of the plurality of steps 4; a movable handrail 6, which is arranged on the upper part of the pair of handrails 5 and moves synchronously with the plurality of steps 4; a skirt 7, which is arranged on the lower part of the pair of handrails 5; and a driving device 30 not shown in the figure, which supplies power in a manner that the movable handrail 6 rotates around the handrail 5.

[0055] Figure 2 It is a diagram showing the internal structure of the end post portion 8. Figure 3 yes Figure 1 The AA section view is a section view of the handrail 5 and the movable handrail 6. Figure 2 , Figure 3 In the embodiment, the handrail 5 includes a guardrail 12 and a panel 11 constituting a base of the handrail 5. In addition, a roller 13 and a roller shaft 14 are provided between the handrail 5 and the movable handrail 6.

[0056] The guardrail 12 is installed on the upper end surface of the panel 11 to guide the movable handrail 6. Figure 2 In the embodiment, the guardrail 12 is formed by connecting a plurality of guardrail parts 15a along the moving direction of the moving handrail 6. Here, one guardrail part 15a is formed in a shape in which the guardrail 12 is divided in the moving direction of the moving handrail 6. For example, Figure 2 As shown, the guardrail member 15a is formed in a shape obtained by dividing the guardrail 12 at the end post portion 8 into nine parts.

[0057] exist Figure 3 In the embodiment, the guardrail member 15a includes: a main body 17, which is fitted into the panel 11; a roller mounting portion 18, which extends from the main body 17 toward the moving handrail 6 and is used to mount the roller 13 provided between the guardrail 12 and the moving handrail 6; and a moving handrail support portion 19, which extends from the roller mounting portion 18 toward the outer side in the width direction of the moving handrail 6 and is used to support the moving handrail 6. The roller mounting portion 18, for example, extends vertically from the main body 17 toward the moving handrail 6 and forms a groove with a concave cross-section.

[0058] In addition, the guardrail member 15a has a through hole 16 that penetrates in the moving direction of the moving handrail 6. Figure 3 As shown, the through hole 16 is provided in the main body 17 .

[0059] The roller 13 is disposed between the guardrail 12 and the movable handrail 6 to reduce the friction force generated between the guardrail 12 and the movable handrail 6. The roller shaft 14 is mounted on the roller mounting portion 18 of the guardrail 12 to support the roller 13.

[0060] Next, a method for manufacturing the guardrail 12 in the curved section 40 is described. When manufacturing the guardrail 12 in the curved section 40, first, a plurality of guardrail components 15a are formed by casting. The casting is, for example, lost wax casting. Next, the wire 20 is passed through the through hole 16 of each guardrail component 15a after the molding. And, the guardrail components 15a are installed in a manner connected along the moving direction of the moving handrail 6. In this way, a guardrail 12 in the curved section 40 in which a plurality of guardrail components 15a are integrated is manufactured. As the curved section 40, for example, a guardrail 12 is manufactured in the end column portion 8 Figure 2 The guardrail 12 is shown.

[0061] Next, a method for inspecting the guardrail 12 in the curved section 40 during manufacturing or maintenance will be described. Figure 4 It is a flowchart showing a method of inspecting the guardrail 12 in the curved section 40 during manufacturing or maintenance.

[0062] exist Figure 4 In the process, first, a dimensional inspection is performed to check whether the guardrail 12 maintains a predetermined dimensional accuracy of the guardrail 12 ( S1 ).

[0063] Next, when the operator determines that the shape of the guardrail 12 needs to be adjusted through the inspection in S1 ("Yes" in S2), the guardrail component 15a having the portion where the shape of the guardrail 12 needs to be adjusted (hereinafter, the guardrail component 15a is referred to as the guardrail component 15b) is taken out. Specifically, the operator unties the wire 20 passing through the through holes 16 of the plurality of guardrail components 15a, separates the plurality of guardrail components 15a from the guardrail 12 integrated by the wire 20, and takes out the guardrail component 15b (S3).

[0064] Next, the operator adjusts the shape of the portion of the taken-out guardrail member 15b that needs to be adjusted (S4) and then checks whether the shape of the entire guardrail member 15b has changed due to the adjustment (S5).

[0065] When the operator determines through the inspection in S5 that the shape of the guardrail component 15b needs to be adjusted ("Yes" in S6), the operator adjusts the shape of the portion of the guardrail component 15b that needs to be adjusted (S4), and then checks whether the overall shape of the guardrail component 15b has changed through the adjustment (S5).

[0066] When the operator determines that the shape of the guardrail component 15b does not need to be adjusted through the inspection in S5 ("No" in S6), the wire 20 is passed through the through holes 16 of the plurality of guardrail components 15a including the guardrail component 15b to connect the plurality of guardrail components 15a including the guardrail component 15b (S7). This operation completes the inspection of the guardrail 12.

[0067] When the operator determines that the shape of the guardrail 12 does not need to be adjusted through the inspection in S1 (No in S2 ), the inspection of the guardrail 12 is terminated.

[0068] According to the above, the curved section 40 of the guardrail 12 of the passenger conveyor 1a is formed by connecting a plurality of guardrail components 15a constituting the guardrail 12 along the moving direction of the moving handrail 6. In addition, the guardrail component 15a is a shape obtained by dividing the guardrail 12 in the moving direction of the moving handrail 6. Thus, when manufacturing or maintaining the guardrail 12, in the case where there is a guardrail component 15b having a portion that needs to be adjusted, only the guardrail component 15b can be taken out. Then, the portion of the guardrail component 15a that needs to be adjusted in shape is adjusted, and it is checked whether the overall shape of the guardrail component 15b has changed due to the adjustment, and the inspection of the guardrail 12 is completed. Therefore, it is not necessary to check the change in the overall shape of the guardrail 12 after adjusting a portion of the guardrail 12, as in the conventional guardrail 12. Therefore, it is possible to reduce the working hours during manufacturing or maintenance.

[0069] Furthermore, the guardrail member 15a has the through hole 16 penetrating in the moving direction of the moving handrail 6, thereby making it possible to simplify the assembly of the guardrail member 15a.

[0070] In addition, the manufacturing method of the guardrail 12 of the passenger conveyor 1a includes the following steps: forming the guardrail parts 15a connected along the moving direction of the moving handrail 6 in the curved section of the guardrail 12 by casting; and the step of connecting the guardrail parts 15a to each other, thereby making it possible to manufacture the guardrail 12 without bending the guardrail 12 in the curved section 40. Therefore, the guardrail 12 can be manufactured while suppressing the change in size and cross-sectional shape caused by bending. In addition, since it is a manufacturing method that does not require bending, it is possible to manufacture the guardrail parts 15a having a complex structure.

[0071] As a guardrail having a complex structure, for example, holes into which the roller shaft 14 can be inserted can be formed on the left and right side portions of the groove having a concave cross-section of the roller mounting portion 18. The roller shaft 14 can be supported by inserting the roller shaft 14 into the two holes provided on the left and right side portions of the groove.

[0072] In addition, in Embodiment 1, an example is described in which the guardrail part 15a is divided into 9 parts in the moving direction of the moving handrail 6 of the guardrail 12, but the number of parts into which the guardrail part 15a is divided in the moving direction of the moving handrail 6 of the guardrail 12 is not limited to this.

[0073] In addition, in embodiment 1, an example is described in which the roller mounting portion 18 extends vertically from the main body 17 toward the movable handrail 6 and forms a groove with a concave cross-section, but the roller mounting portion 18 can be any shape as long as it can mount the roller 13 and extend from the main body 17 toward the movable handrail 6 side, and is not limited to this.

[0074] In the first embodiment, the through hole 16 in the guardrail member 15a is provided in the main body 17 of the guardrail member 15a, but the location of the through hole 16 is not limited as long as the guardrail member 15a is formed in a manner that allows the guardrail member 15a to be connected in the direction in which the movable handrail 6 moves. For example, the through hole 16 may be provided in the roller mounting portion 18 or the movable handrail support portion 19a.

[0075] In the first embodiment, lost wax casting is used as an example of a molding method for the guardrail member 15a, but any method may be used as long as the molding method is casting, and the method is not limited to this. For example, the guardrail member 15a may be molded by die gravity casting.

[0076] In the first embodiment, the inspection in S1 and S5 and the determination in S2 and S6 are performed by an operator, but the present invention is not limited to this. For example, a machine that automatically performs the inspection and determination may be used.

[0077] In the first embodiment, the dimension inspection is performed in S1, but the specific inspection method in S1 is not limited to the dimension inspection as long as the inspection is performed after S1 in the process of adjusting the shape of the guardrail 12. For example, a material test may be performed to check whether the cross-sectional shape of the guardrail 12 has not changed.

[0078] Implementation method 2.

[0079] The structure of the guardrail member 15c of the passenger conveyor 1c in the second embodiment will be described. Figure 5 It is a cross-sectional view of the handrail 5c and the movable handrail 6. Figure 6 15c is a cross-sectional view of the guardrail member 15c. Figure 5 and Figure 6 The cross section in Figure 1 The cross section of the passenger conveyor 1c is cut in the same section as section AA in the passenger conveyor 1a shown. In addition, the passenger conveyor 1c is omitted from the illustration. The guardrail member 15c in the second embodiment is different from the first embodiment in that the hardness of the movable handrail support portion 19c is lower than the hardness of the main body portion 17 and the roller mounting portion 18. In addition, the same reference numerals are given to the same structures as those in the first embodiment and their descriptions are omitted.

[0080] exist Figure 5 , Figure 6 In the figure, the handrail 5c includes a panel 11 and a guardrail 12c formed by connecting guardrail members 15c in the moving direction of the moving handrail 6. In addition, illustration of the guardrail 12c is omitted.

[0081] The guardrail member 15c includes a main body 17, a roller mounting portion 18, and a moving handrail support portion 19c. The main body 17 and the roller mounting portion 18 are made of, for example, metal, and the moving handrail support portion 19c is made of, for example, resin.

[0082] When a passenger uses the moving handrail 6 by grasping it, the passenger's palm contacts the upper surface of the moving handrail 6, and the passenger's fingers contact the moving handrail support portion 19c exposed from the moving handrail 6. Here, the moving handrail 6 is made of a material with low hardness, such as rubber and polyurethane, in consideration of the contact with the passenger's hand. In addition, the moving handrail support portion 19c in the past is formed as an integrated guardrail component 15c, and therefore a metal material with high hardness is mostly used. Therefore, in the handrail 5c of the previous passenger conveyor 1c, when the passenger's fingers violently contact the previous moving handrail support portion 19c, the passenger's fingers may be injured. On the other hand, in the present embodiment, the moving handrail support portion 19c uses a material with low hardness, so even if the passenger's fingers contact the moving handrail support portion 19c, the possibility of injury to the passenger's fingers can be reduced.

[0083] The guardrail member 15c is molded by insert molding. In insert molding, after the main body 17 and the roller mounting portion 18 are molded by metal, the moving handrail support portion 19c is molded by resin, so that the main body 17, the roller mounting portion 18 and the moving handrail support portion 19c are integrally molded.

[0084] According to the above, the guardrail member 15c includes: a main body 17, which is fitted into the panel 11 constituting the base of the handrail 5c; a roller mounting portion 18, which extends from the main body 17 toward the moving handrail 6 side and is used to mount the roller 13 provided between the guardrail 12c and the moving handrail 6; and a moving handrail support portion 19c, which extends from the roller mounting portion 18 toward the outer side in the width direction of the moving handrail 6 and is used to support the moving handrail 6, and the hardness of the material of the moving handrail support portion 19c is lower than the hardness of the material of the main body 17 and the roller mounting portion 18. Thus, when the passenger of the passenger conveyor 1c uses the moving handrail 6 in a manner of grasping it, even if the passenger's fingers come into contact with the moving handrail support portion 19c, the possibility of injury to the passenger's fingers can be reduced.

[0085] In addition, by integrally molding the main body 17, the roller mounting portion 18, and the movable handrail support portion 19c, when manufacturing the guardrail component 15c, it is not necessary to assemble the components divided into the main body 17, the roller mounting portion 18, and the movable handrail support portion 19c, thereby reducing the number of components.

[0086] In addition, in Embodiment 2, an example is described in which the material of the main body 17 and the roller mounting portion 18 is metal, and the material of the movable armrest support portion 19c is resin, but as long as the hardness of the material of the movable armrest support portion 19c is lower than the hardness of the material of the main body 17 and the roller mounting portion 18, the materials of the main body 17, the roller mounting portion 18 and the movable armrest support portion 19c are not limited to this.

[0087] Implementation method 3.

[0088] The structure of the guardrail member 15d of the passenger conveyor 1d in the third embodiment will be described. Figure 7 It is a figure which shows the guardrail member 15d. Figure 7 (a) is a front view of the guardrail component 15d, Figure 7 (b) is a side view of the guardrail member 15d. Figure 8 1 is a diagram showing the internal structure of the end column 8. In addition, the passenger conveyor 1d is omitted from the figure. The guardrail member 15d in the third embodiment is different from the first embodiment in that a concave portion 22 or a convex portion 23 is provided on the surface where the guardrail members 15d contact each other. In addition, the same reference numerals are given to the same structures as those in the first embodiment and their description is omitted.

[0089] exist Figure 7 , Figure 8 In the guardrail member 15d shown, a recessed portion 22 is provided on one surface where the guardrail members 15d are in contact with each other, and a convex portion 23 is provided on the other surface. The recessed portion 22 and the convex portion 23 can be engaged with each other, and the guardrail 12d is formed by connecting a plurality of guardrail members 15d. The recessed portion 22 and the convex portion 23 are provided, for example, at the lower portion of the main body 17 on the surface where the guardrail members 15d are in contact with each other. Figure 8 In FIG. 1 , the portion where the concave portion 22 and the convex portion 23 fit together is represented as a concave-convex fitting portion 24 .

[0090] As described above, the guardrail member 15d is provided with the recessed portion 22 or the convex portion 23 on the surface where the guardrail members 15d contact each other, and the recessed portion 22 and the convex portion 23 can be fitted, thereby simplifying the assembly of the guardrail member 15a.

[0091] In addition, in embodiment 3, an example is described in which the recess 22 and the protrusion 23 are arranged in the lower part of the main body 17 on the surface where the guardrail part 15d contacts each other, but as long as the recess 22 and the protrusion 23 are arranged in a manner that allows them to fit together, the location where the recess 22 and the protrusion 23 are arranged is not limited.

[0092] Furthermore, in Embodiment 3, the concave portion 22 is provided on the surface of one side where the guardrail components 15d are in contact with each other, and the convex portion 23 is provided on the surface of the other side, but the combination of the concave portion 22 or the convex portion 23 provided on the surface of the guardrail components 15d in contact with each other is not limited thereto. As long as the guardrail components 15d can be connected in a manner that the concave portion 22 and the convex portion 23 can be engaged, for example, the guardrail components 15d may have the concave portion 22 formed on the surface of one side where the guardrail components 15d are in contact with each other and the other side, and the convex portion 23 may be formed on the surface of one side where the guardrail components 15d are in contact with each other and the other side.
