In the following, referring also to FIGS. 5 to 10, a method of manufacturing the movable armrest 7 will be described. FIG. 5 is a diagram for explaining the manufacturing method of the mobile armrest 7.

First, a long armrest body 15 is manufactured by extrusion molding or the like. The cross section of the armrest body 15 is the same as the cross section shown in FIG. 4. That is, the armrest body 15 has a substantially C-shaped transverse cross section. The armrest body 15 includes, for example, a body resin portion 10, a tension member 11, and a canvas 12.

Next, the armrest body 15 is cut to a desired length, and the end portion 15a and the end portion 15b of the armrest body 15 are joined to each other. Fig. 5 shows a state before joining the end portion 15a and the end portion 15b. Fig. 6 is a view of the armrest body 15 shown in Fig. 5 viewed from the D direction. FIG. 7 is a diagram showing the E-E cross section of FIG. 5. FIG. FIG. 5 shows an example in which the armrest body 15 is cut diagonally into a straight line. The step may be formed at the end 15a and the end 15b so that the tension member 11 of the moving armrest 7 overlaps.

When joining the end portion 15a and the end portion 15b, first, the notches 16a and 16b are formed in the end portion 15a. The notch 16a is formed in the rail holding portion 14 on one side of the end portion 15a. The notch 16a is opened at the end surface of the end portion 15a and the outer surface of the rail holding portion 14. The openings of the notch 16a are formed in series. The notch 16a is formed in the body resin portion 10 such that the lateral cross section of the armrest body 15 extends toward the front end of the rail holding portion 14, for example. The notch 16b is formed in the other rail holding portion 14 of the end portion 15a. The notch 16b is opened at the end surface of the end portion 15a and the outer surface of the rail holding portion 14. The openings of the notch 16b are formed in series. The notch 16b is formed in the body resin portion 10 such that the lateral cross-section of the armrest body 15 extends toward the front end of the rail holding portion 14, for example.

In addition, notches 17a and 17b are formed in the end portion 15b. Notch 17a The rail holding portion 14 formed on one side of the end portion 15b. The notch 17a is opened at the end surface of the end portion 15b and the outer surface of the rail holding portion 14. The opening of the notch 17a is formed in series. The notch 17a is formed in the body resin portion 10 such that the lateral cross section of the armrest body 15 extends toward the front end of the rail holding portion 14, for example. The notch 17b is formed in the other rail holding portion 14 of the end portion 15b. The notch 17b is opened at the end surface of the end portion 15b and the outer surface of the rail holding portion 14. The opening of the notch 17b is formed in series. The notch 17b is formed in the body resin portion 10 such that the lateral cross section of the armrest body 15 extends toward the front end of the rail holding portion 14, for example.

The notch 16a formed in the end 15a and the notch 17a formed in the end 15b are formed in series when the end face of the end 15a and the end face of the end 15b are joined together. The notch 16b formed in the end 15a and the notch 17b formed in the end 15b are formed in series when the end face of the end 15a and the end face of the end 15b are joined together.

When the end portion 15a and the end portion 15b are joined, the reinforcing cloth 13 is arranged in a series of spaces formed in one of the end portion 15a and the end portion 15b by facing the notch 16a and the notch 17a. In addition, the reinforcing cloth 13 is arranged in a space formed in a series of one of the end portion 15a and the end portion 15b by facing the notch 16b and the notch 17b. FIG. 8 is a cross-sectional view showing a state where the reinforcing cloth 13 is inserted into the spaces formed at the end 15a and the end 15b of the armrest body 15. In addition, the end portion 15a and the end portion 15b are arranged in the forming die in a state where the reinforcing cloth 13 is arranged in the respective spaces, and heat forming is performed. When it is arranged in the molding die, an additional resin member for filling these spaces may also be used. Thereby, the end 15a and the end 15b are joined.

FIG. 9 is a diagram showing the reinforcing cloth 13. Regarding the reinforcing cloth 13, a person who has previously impregnated the resin is prepared in advance. By being heated at the time of molding, the resin immersed in the reinforcing cloth 13 melts, and is integrated with the resin constituting the main body resin portion 10. The resin immersed in the reinforcing cloth 13 in advance may be excellent in adhesion with the resin constituting the resin portion 10 of the main body. For example, the same resin as the resin constituting the main body resin portion 10 is suitable.

In addition, regarding the reinforcing cloth 13, it is preferable to prepare in advance those that have been subjected to preheat treatment before performing heat forming. For example, a thermoplastic resin of the same type as the resin constituting the main body resin portion 10 may be melted and included in the reinforcing cloth 13. By using the reinforcing cloth 13 which has been subjected to the pre-heat treatment, the shrinkage of the reinforcing cloth 13 at the time of heat forming can be suppressed. Thereby, the offset of the reinforcing cloth 13 can be suppressed at the time of thermoforming.

According to this step, the mobile armrest 7 of the cross section shown in FIGS. 2 and 3 can be manufactured. FIG. 10 is a view showing the F-F section of FIG. 3. FIG. As shown in FIG. 10, the reinforcing cloth 13 is provided inside the rail holding portion 14 at the joint portion of the moving armrest 7. For example, when the moving armrest 7 is reversed up and down at the boarding and landing port 2 and the boarding and landing port 3, a large stress does not act on the flat portion of the moving armrest 7 including the tension member 11. The stress system mainly acts on the rail holding portion 14. If the mobile armrest 7 has this structure, the reinforcing cloth 13 can sufficiently ensure the joint strength of the rail holding portion 14. By using the reinforcing cloth 13 in which the resin has been impregnated in advance, the reinforcing cloth 13 and the main body resin portion 10 can be integrated.

The reinforcing cloth 13 is excellent in flexibility. Since a member made of metal or the like is not used as a member that reinforces the rail holding portion 14 of the joint portion, sufficient flexibility can be ensured in the rail holding portion 14. Can make the track of the joint part fixed The holding portion 14 is easily deformed to match the curvature of the guide rail.

As shown in FIG. 10, the reinforcing cloth 13 is not exposed on the surface of the moving armrest 7. That is, the surface of the reinforcing cloth 13 on the inner side of the moving armrest 7 is not exposed. The reinforcing cloth 13 will not peel off due to the contact between the moving armrest 7 and the guide rail. Therefore, the maintenance of the mobile handrail 7 can be easily performed, and the manpower and time required for the maintenance of the escalator can be shortened.

In addition, at the joint portion of the moving armrest 7, as shown in FIG. 10, the end of the canvas 12 is pressed into the body resin portion 10 side. Furthermore, the opening resin 18 is filled so as to cover both ends of the canvas 12. This prevents the canvas 12 from peeling off.

Fig. 11 is a diagram for explaining another method of manufacturing a mobile armrest. When the reinforcing cloth 13 is arranged in the space formed at the end 15a and the end 15b of the armrest body 15, as shown in FIG. 11, the reinforcing cloth may be arranged along the canvas 12 in the lateral cross section of the main body resin portion 10 13. By arranging the reinforcing cloth 13 along the canvas 12, the joint strength of the rail holding portion 14 can be further improved.
