FIG. 4 is a front perspective view of the moving handrail 15 with the opening 60 facing upward.
As shown in FIG. 4, the moving handrail 15 includes a moving handrail main body 30 having a C-shaped cross section, and a canvas 40 provided on the inner surface of the moving handrail main body 30.

  The moving handrail main body 30 has a flat plate portion 31 extending in the longitudinal direction of the moving handrail 15 and a pair of curved portions 32 provided at both end portions 30 a in the width direction of the flat portion 31. As shown in FIG. 4, curved portions 32 continuously provided at both end portions 30 a of the flat plate portion 31 have a curved shape (R portion) which bulges outward in the width direction of the moving handrail 15. That is, the cross-sectional shape of the moving handrail main body 30 is a flat C-shape by the flat plate portion 31 and the pair of curved portions 32. In addition, the moving handrail main body 30 of this example is integrally molded, for example with a synthetic rubber.

  An opposing surface 33 is formed at an end 30b opposite to the end 30a of the curved portion 32, and the opposing surface 33 is disposed at a predetermined interval. That is, an opening 60 for opening the internal space of the moving handrail 15 is formed along the longitudinal direction of the moving handrail 15 by the pair of facing surfaces 33.

  An inner circumferential surface in the opening 60 of the movable handrail main body 30 forms a contact surface 301 in contact with the guide piece 230. Further, the outer peripheral surface of the moving handrail main body 30 forms a gripping surface 302 for the user to grip.

  The contact surface 301 of the movable handrail main body 30 is a sliding surface area 301 a that slides on the upper sliding plane 24 of the handrail guide 23 and an engaging contact surface area that contacts the engaging projection 26 of the handrail guide 23 in the forward path. And 301 b. The sliding surface area 301a is also in contact with the driving wheel 19 of the handrail drive device 18 described above.

  The sliding surface area 301 a is formed on the inner peripheral surface of the flat plate portion 31, and the engaging contact surface area 301 b is formed on the inner peripheral surface of the curved portion 32.

FIG. 5 is an enlarged front view of the curved portion 32 of the moving handrail 15 of FIG.
As shown in FIG. 5, the engaging contact surface area 301b is a curved surface area 311a in contact with the engaging projection 26 of the handrail guide 23, and a flat area 311b sliding on the lower sliding flat surface 25 of the guide piece 230. And consists of.

  The curved surface area 311 a is formed on the inner peripheral surface of the R portion 321 of the curved portion 32.

  The flat region 311 b is formed on the inner circumferential surface from the end 321 a of the R portion 321 to the end 30 b.

  The facing surface 33 is provided with an embedded area 311 c for embedding the end of the canvas 40.

  As shown in FIG. 4, the canvas 40 is provided so as to cover the sliding surface area 301 a and the engaging contact surface area 301 b of the moving handrail main body 30. The canvas 40 is formed by weaving a plurality of fibers made of, for example, cotton or polyester, and in the present example, a plurality of canvass 40 are overlapped.

  Both ends in the width direction of the canvas 40 are bent outward in the width direction of the movable handrail main body 30 at the opening 60 and are buried in the embedded area 311 c. In addition, you may stick and fix to the embedding area | region 311c as it is, without bending the both ends of the canvas 40. FIG.

  In the present example, a slit (cut) 42 is provided in the canvas 40 of the engagement contact surface area 301 b. A plurality of slits 42 are formed to extend in the width direction of the canvas 40, and are arranged at equal intervals along the longitudinal direction of the canvas 40 as shown in FIG.

  The cross-sectional shape of the slit 42 formed in the canvas 40 is, for example, a cross-sectional I-shaped structure as shown in FIG. 6A, a U-shaped cross-sectional structure as shown in FIG. 6B, or a cross-sectional square as shown in FIG. It is possible to use a shape structure, a cross-sectional V-shaped structure as shown in FIG. 6D. The sectional shape of the slit 42 is formed by using a special jig.

  As described above, in the present embodiment, the bending resistance of the moving handrail 15 can be reduced by providing the plurality of slits 42 in the canvas 40 of the moving handrail 15. In particular, by providing the slits 40 in the engaging contact surface area 301b of the curved portion 32 of the moving handrail 15 where the bending resistance increases, the bending rigidity of the curved portion 32 can be reduced and the bending resistance can be reduced. As a result, it becomes easy to cause the moving handrail 15 in motion to follow the handrail guide 23, and breakage of the moving handrail 15 can be prevented.

  Further, in the present embodiment, by forming the slits 42 only in the engaging contact surface area 301b of the curved portion 32, the influence of the contact with the upper sliding plane 24 of the handrail guide 23 in the forward path can be reduced. Moreover, the influence of the load received from the drive wheel 19 of the handrail drive device 18 in the return path can be reduced. Therefore, it is possible to prevent the slit 42 from being worn and losing its function or peeling off the canvas 40 from the slit 42 due to friction or load.

  Furthermore, by forming the slits 42 only in the curved surface area 311 a of the curved portion 32, the influence of the load due to the weight of the movable handrail 15 in the return path can be reduced. That is, although the flat area 311b and the lower sliding plane 25 of the handrail guide 23 contact in the return path, the width of the flat area 311b is small, so the load by the weight of the moving handrail 15 is large. For this reason, abrasion of the slits 42 and peeling of the canvas 40 easily occur, but by forming the slits 42 only in the curved surface area 311 a, abrasion of the slits 42 and peeling of the canvas 40 can be reduced.

  In addition, by not forming the slits 42 in the embedded area 311 c, the strength of the embedded portion of the canvas 40 can be maintained, and the canvas 40 can be made difficult to be peeled off from the moving handrail main body 30.

FIG. 7 is another example of the slit formed in the canvas 40.
As shown in FIG. 7, in the present example, the slits 421 are formed along the longitudinal direction of the canvas 40. According to the present embodiment, since it is sufficient to form a single linear slit, the slit 421 can be formed by a relatively simple operation. Further, by forming the slit 421 only in the engaging contact surface area 301 b of the curved portion 32, the influence of the contact with the drive wheel 19 of the handrail drive device 18 and the upper sliding plane 24 of the handrail guide 23 with respect to the slit 421 is reduced. can do.

FIG. 8 is another example of the slit formed in the canvas 40.
As shown in FIG. 8, the slits 422 of this example are formed by orthogonalizing a plurality of slits 42 formed in the width direction of the canvas 40 and slits 421 formed along the longitudinal direction of the canvas 40. There is. According to this embodiment, the bending rigidity of the bending portion 32 can be lowered according to the direction in which the movable handrail 15 is deformed by making the direction of the slit cut different. Further, by forming the slit 422 only in the engaging contact surface area 301b of the curved portion 32, the influence of the contact with the drive wheel 19 of the handrail drive device 18 and the upper sliding plane 24 of the handrail guide 23 with respect to the slit 422 is reduced. can do.

  The above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to one having all the described configurations. For example, part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Moreover, it is possible to add, delete, and replace other configurations for part of the configurations of the respective embodiments.

  The shape of the slits formed in the canvas 40 is not limited to the shape disclosed in the present embodiment. Further, the plurality of slits do not necessarily have to be arranged at equal intervals.
