[0009] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0010] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0011] An embodiment of a passenger conveyor, a passenger conveyor balustrade device, and a female screw material will be described below with reference to Figures 1 to 7. Note that the following embodiment is provided as an example to aid in understanding the configurations of the passenger conveyor, the passenger conveyor balustrade device, and the female screw material, and does not limit the configurations of the passenger conveyor, the passenger conveyor balustrade device, and the female screw material.

[0012] As shown in Figure 1, a passenger conveyor 1 may, for example, comprise a structure 2 installed on a main body, a transport section 3 for transporting people (passengers), a pair of passenger conveyor balustrade devices (hereinafter simply referred to as "balustrade devices") 4 (only one is shown in Figure 1) arranged to sandwich the transport section 3 in a first direction D1, and a drive section 5 for driving the transport section 3 and the balustrade device 4.

[0013] In Figure 1, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 perpendicular to the first horizontal direction D1, the third direction D3 is the vertical direction D3, the fourth direction is the direction in which the conveying section 3 conveys the person and is a conveying direction D4 that is inclined with respect to the second horizontal direction D2 when viewed from the first horizontal direction D1, and the fifth direction D5 is a conveying vertical direction D5 perpendicular to the conveying direction D4 when viewed from the first horizontal direction D1.

[0014] The passenger conveyor 1 according to this embodiment is an escalator with a stepped tread surface for transporting passengers, but is not limited to such a configuration. For example, the passenger conveyor 1 may be a moving walkway with a flat tread surface for transporting passengers.

[0015] The structure 2 may include, for example, machine rooms 2a, 2a arranged at each end in the second horizontal direction D2 as in this embodiment. The structure 2 may also be, for example, a truss structure or a girder structure composed of a plurality of frame materials.

[0016] The transport unit 3 may include, for example, as in this embodiment, an endless annular running unit 3a that rotates and runs when driven by the drive unit 5, and a plurality of steps 3b that are connected to the running unit 3a and run together with the running unit 3a, and have tread surfaces on which people can stand. Although not particularly limited, the running unit 3a may be, for example, a roller chain.

[0017] Also, for example, the running parts 3a may be provided in a pair spaced apart from each other in the first horizontal direction D1, and the steps 3b may be disposed between the pair of running parts 3a, 3a. The steps 3b may be connected to each running part 3a so as to be rotatable about the first horizontal direction D1.

[0018] The driving unit 5 may include, for example, as in this embodiment, a rotating unit 5a around which a first end of the running unit 3a in the second horizontal direction D2 is wound and which rotates about an axis in the first horizontal direction D1, a running support unit 5b that supports a second end of the running unit 3a in the second horizontal direction D2, and a driving source 5c that rotates the rotating unit 5a. As a result, the step 3b is reversed by the rotating unit 5a and also reversed by the running support unit 5b.

[0019] Although not particularly limited, the rotating part 5a may be, for example, a sprocket. Furthermore, although not particularly limited, the running support part 5b may be, for example, a guide member that guides the running part 3a to rotate in an inverted manner, or may be, for example, a rotating member (for example, a sprocket) around which the running part 3a is wound and which rotates about an axis in the first horizontal direction D1. Furthermore, although not particularly limited, the driving source 5c may be, for example, a motor.

[0020] 1 to 3, the balustrade device 4 may include, for example, an endless circular handrail belt 4a that rotates and runs, a panel 6 formed in a flat plate shape, a guide material 7 into which the upper end of the panel 6 is inserted and which guides the handrail belt 4a, a frame material 8 into which the lower end of the panel 6 is inserted, and a panel support part 9 that supports the panel 6 by supporting the frame material 8. Note that, for example, the handrail belt 4a may run by being driven by a drive part 5, and the running of the handrail belt 4a may be synchronized with the running of the steps 3b.

[0021] 2 and 3 (as well as in FIGS. 4 to 10), the first direction D1 is the first horizontal direction D1, which is the thickness direction D1 of the panel 6, the sixth direction D6 is the height direction D6 of the panel 6, and the seventh direction D7 is the width direction D7 of the panel 6. The height direction D6 may be, for example, the vertical direction D3 or the transport vertical direction D5, and the width direction D7 may be, for example, the second horizontal direction D2 or the transport direction D4.

[0022] In this specification, unless otherwise specified, "upper (upper side, upper end, upper end, etc.)" means upper (upper side, upper end, upper end, etc.) in the height direction D6, and "lower (lower side, lower end, lower end, etc.)" means lower (lower side, lower end, lower end, etc.) in the height direction D6. In addition, in this specification, unless otherwise specified, the thickness direction D1, height direction D6, and width direction D7 mean the respective directions D1, D6, and D7 in the panel 6 installed on the balustrade device 4.

[0023] For example, as in this embodiment, a plurality of panels 6 may be provided and arranged in contact with each other in the width direction D7 (second horizontal direction D2 or transport direction D4). Although not particularly limited, the panel 6 may be formed of, for example, glass or hard resin. Also, for example, as in this embodiment, a plurality of panel support portions 9 may be provided and arranged apart from each other in the width direction D7 (second horizontal direction D2 or transport direction D4).

[0024] 2 and 3, the balustrade device 4 may include, for example, a fixing means 4b for fixing the panel support portion 9 to the structure 2, a cover material 4c for covering the lower end of the panel 6, the frame material 8, and the panel support portion 9, and a sealant 4d for sealing between the cover material 4c and the frame material 8. Although not particularly limited, the fixing means 4b may be configured to be capable of changing the position of the panel support portion 9 in the height direction D6 relative to the structure 2, as in this embodiment.

[0025] The panel support portion 9 may, for example, as in this embodiment, have a support recess 9a into which the lower portion of the frame material 8 is inserted. In this way, the panel support portion 9 supports the frame material 8. Also, the balustrade device 4 may, for example, as in this embodiment, have a wedge member 4e that is inserted into the support recess 9a in order to fix the frame material 8 to the panel support portion 9.

[0026] The guide material 7 may have a guide recess 7a into which the upper end of the panel 6 is inserted, as in this embodiment. This allows the guide material 7 to be supported by the panel 6. Also, the guide material 7 may extend in the width direction D7 along the upper end of the multiple panels 6 that are arranged, as in this embodiment.

[0027] 2 to 4, the frame material 8 may have, for example, a frame recess 8a into which the lower end portion of the panel 6 is inserted. Furthermore, the frame material 8 may extend in the width direction D7 along the lower end portions of the multiple panels 6 that are arranged, as in this embodiment. In this way, the lower end portions of the multiple panels 6 are inserted into the frame recess 8a of the frame material 8.

[0028] The bottom 8b of the frame recess 8a may include, for example, a pair of bottom side surfaces 8c, 8c separated in the thickness direction D1, a concave bottom surface 8d connecting the pair of bottom side surfaces 8c, 8c, and a hole 8e penetrating in the height direction D6, as in the present embodiment. Also, the frame material 8 may include, for example, frame connecting portions 8f, 8f extending from the upper end of the frame recess 8a in the thickness direction D1 and connected to the sealing material 4d, as in the present embodiment.

[0029] Furthermore, the balustrade device 4 may include an insert 4f that is sandwiched between the panel 6 and the frame material 8 in the height direction D6 to form a gap in the height direction D6 between the panel 6 and the frame material 8, as in this embodiment. Although not particularly limited, the insert 4f may be made of, for example, an elastic material (e.g., rubber).

[0030] Incidentally, for example, by stabilizing the support of the guide material 7 by the panel 6, the running of the handrail belt 4a can be stabilized, so it is necessary to align the positions of the upper ends of the multiple panels 6 arranged in the height direction D6. On the other hand, for example, the sizes of the panels 6 (for example, the dimensions in the height direction D6) may differ slightly.

[0031] 5 to 7, the balustrade device 4 may, for example, be provided with a change mechanism 11 capable of changing the position of the panel 6 in the height direction D6 relative to the frame material 8. The change mechanism 11 may, for example, be provided with a female threaded material 12 disposed below the panel 6, and a male threaded material 13 that screws into the female threaded material 12.

[0032] As a result, the female threaded material 12 and the male threaded material 13 have threaded portions 12a, 13a (specifically, the female threaded portion 12a and the male threaded portion 13a) that screw together. Note that in Fig. 5, the frame material 8 is shown in vertical cross section, and in Figs. 7(a) and 7(b), the male threaded material 13 is shown by a two-dot chain line.

[0033] Also, the female threaded material 12 may be detachably attached to the hole 8e of the frame material 8, as in this embodiment, and the male threaded material 13 may be detachably attached to the female threaded material 12, as in this embodiment. As a result, the frame material 8, the female threaded material 12, and the male threaded material 13 are separate parts that can be separated from each other.

[0034] The female threaded material 12 may, for example, as in this embodiment, have a base portion 12b that is accommodated in the bottom portion 8b of the frame recess 8a (placed inside the bottom portion 8b of the frame recess 8a) and a protruding portion 12c that extends downward from the base portion 12b and protrudes downward from a hole 8e of the frame recess 8a. This allows the female threaded material 12 to be attached to the hole 8e of the frame material 8, and the position of the female threaded material 12 relative to the panel support portion 9 (see Figures 2 and 3) to be fixed.

[0035] For example, as in this embodiment, the distance in the thickness direction D1 between the pair of bottom side surfaces 8c, 8c may be decreased toward the bottom, and the width in the thickness direction D1 of the base portion 12b may be decreased toward the bottom. This allows the base portion 12b to fit into the bottom portion 8b of the frame recess 8a, so that the female threaded material 12 can be stably attached to the bottom portion 8b of the frame recess 8a.

[0036] The female thread portion 12a extends upward (in the height direction D6) from the lower end of the protruding portion 12c to the upper end of the female threaded material 12, and the male thread portion 13a extends in the height direction D6. As a result, the male thread portion 13a screws into the female thread portion 12a, so that the male threaded material 13 is inserted into the hole 8e of the frame material 8 via the female threaded material 12.

[0037] For example, as in this embodiment, the length in the width direction D7 of the base portion 12b may be longer than the distance in the thickness direction D1 between the pair of bottom side surfaces 8c, 8c. This allows the base portion 12b to be abutted against the bottom side surface 8c in the axial direction of the female thread portion 12a when the male thread material 13 is screwed into the female thread portion 12a, so that the female thread material 12 can be prevented from rotating together with the male thread material 13. Therefore, for example, the female thread material 12 and the male thread material 13 can be easily screwed into each other.

[0038] Furthermore, by screwing the male thread portion 13a into the female thread portion 12a, the amount by which the male thread material 13 protrudes upward from the female thread material 12 is changed, and the upper end of the male thread material 13 abuts and stops the lower end of the panel 6 from below. This makes it possible to change the position of the height direction D6 of the panel 6 relative to the panel support portion 9 by changing the amount by which the male thread material 13 protrudes upward relative to the female thread material 12. Therefore, for example, even if the sizes of the panels 6 in the height direction D6 are different, the positions of the height direction D6 of the upper ends of multiple panels 6 to be arranged can be aligned.

[0039] The male threaded material 13 may have an operating portion 13b arranged outside the frame recess 8a (at the lower end in this embodiment), for example, as in this embodiment. This allows the male threaded material 13 to be screwed into the female threaded material 12 by operating the male threaded material 13 outside the frame recess 8a. Although not particularly limited, the male threaded material 13 may be a bolt whose head is the operating portion 13b, for example, as in this embodiment.

[0040] In addition, the panel 6 is supported by the frame material 8 via the male screw material 13 and the insert material 4f (see FIG. 2), and the frame material 8 is supported by the panel support portion 9 (see FIG. 2 and FIG. 3). Therefore, the panel 6 is supported by the panel support portion 9 via the male screw material 13, the insert material 4f, and the frame material 8.

[0041] [1] From the above, the passenger conveyor balustrade device 4, as in this embodiment, Panel 6 and A panel support portion 9 that supports the panel 6; a change mechanism 11 capable of changing a position of the panel 6 in a height direction D6 relative to the panel support portion 9, The change mechanism 11 is A female screw member 12 is disposed below the panel 6 and has a fixed position relative to the panel support portion 9; and a male threaded member 13 that is capable of changing the amount of upward projection from the female threaded member 12 by screwing into the female threaded member 12, and whose upper end abuts against the panel 6 from below. This configuration is preferred.

[0042] According to this configuration, the female threaded material 12 is disposed below the panel 6, and the position of the female threaded material 12 relative to the panel support portion 9 is fixed. Then, by screwing the male threaded material 13 into the female threaded material 12, the amount of the male threaded material 13 that protrudes upward from the female threaded material 12 changes, and the upper end of the male threaded material 13 abuts and stops the panel 6 from below. This makes it possible to change the position of the panel 6 in the height direction D6 relative to the panel support portion 9.

[0043] [2] In addition, the passenger conveyor balustrade device 4 of the above [1] is, as in this embodiment, The panel further includes a frame member 8 having a recess (frame recess) 8a into which the lower end of the panel 6 is inserted and supported by the panel support portion 9. The recess 8a has a bottom 8b including a hole 8e penetrating therethrough in the height direction D6. The male screw 13 is inserted into the hole 8e. This configuration is preferred.

[0044] According to this configuration, the lower end of the panel 6 is inserted into a recess (frame recess) 8a of the frame material 8, and the frame material 8 is supported by the panel support portion 9. Then, the male screw material 13 is inserted into a hole 8e provided in a bottom portion 8b of the recess 8a, so that the upper end of the male screw material 13 abuts and stops the panel 6 from below.

[0045] [3] In addition, in the passenger conveyor balustrade device 4 described above in [2], as in this embodiment, The female screw member 12 is detachably attached to the hole 8e of the frame member 8. This configuration is preferred.

[0046] According to this configuration, the position of the female thread material 12 relative to the panel support portion 9 is fixed by fitting the female thread material 12 into the hole 8e of the frame material 8. This allows the female thread material 12 to be a separate part from the frame material 8.

[0047] [4] In addition, in the passenger conveyor balustrade device 4 described above in [3], as in this embodiment, The female screw member 12 is A base portion 12b that is accommodated in a bottom portion 8b of the recess (frame recess) 8a; a protruding portion 12c extending downward from the base portion 12b and protruding downward from the hole 8e; and a female screw portion 12a extending upward from the lower end of the protruding portion 12c and screwed into the male screw material 13. This configuration is preferred.

[0048] According to this configuration, the base portion 12b is accommodated in the bottom portion 8b of the recess (frame recess) 8a of the frame material 8, and the protrusion 12c extends downward from the base portion 12b and protrudes downward from the hole 8e of the frame material 8. This allows the female threaded material 12 to be attached to the hole 8e of the frame material 8, and the position of the female threaded material 12 relative to the panel support portion 9 can be fixed.

[0049] The female screw portion 12a extends upward from the lower end of the protruding portion 12c, and the male screw material 13 screws into the female screw portion 12a. As a result, the male screw material 13 is inserted into the hole 8e of the frame material 8, and the upper end of the male screw material 13 abuts against the panel 6 from below.

[0050] [5] In addition, in the passenger conveyor balustrade device 4 described above in [4], as in this embodiment, The bottom 8b of the recess (frame recess) 8a has a pair of bottom side surfaces 8c, 8c that are spaced apart in the thickness direction D1 of the panel 6, The length of the base portion 12b in a direction (width direction) perpendicular to the thickness direction D1 is longer than the distance between the pair of bottom side surfaces 8c, 8c. This configuration is preferred.

[0051] According to this configuration, the length of the base portion 12b in the direction (width direction) D7 perpendicular to the thickness direction D1 is longer than the distance between the pair of bottom side surfaces 8c, 8c, so that the base portion 12b is abutted against the bottom side surface 8c in the axial direction of the female screw portion 12a. This makes it possible to prevent the female screw material 12 from rotating together with the male screw material 13 when the male screw material 13 is screwed into the female screw portion 12a.

[0052] [6] In addition, in the passenger conveyor balustrade device 4 of the above [4] or [5], as in this embodiment, The bottom 8b of the recess (frame recess) 8a has a pair of bottom side surfaces 8c, 8c that are spaced apart in the thickness direction D1 of the panel 6, The distance between the pair of bottom sides 8c, 8c becomes smaller as it goes downward, The width of the base portion 12b in the thickness direction D1 becomes smaller toward the bottom. This configuration is preferred.

[0053] According to this configuration, the distance between the pair of bottom side surfaces 8c, 8c decreases toward the bottom, while the width of the base portion 12b in the thickness direction D1 decreases toward the bottom. As a result, for example, the base portion 12b fits into the bottom portion 8b of the recess (frame recess) 8a, so that the female screw material 12 can be stably attached to the bottom portion 8b of the recess 8a of the frame material 8.

[0054] [7] In addition, the passenger conveyor 1, as in this embodiment, Equipped with any one of the passenger conveyor handrail devices 4 described above in [1] to [6], This configuration is preferred.

[0055] According to this configuration, the position of the panel 6 relative to the panel support portion 9 in the height direction D6 can be changed.

[0056] [8] In addition, the female thread material 12, as in this embodiment, Used in any one of the passenger conveyor handrail devices 4 described above in [3] to [6], This configuration is preferred.

[0057] According to this configuration, the position of the panel 6 relative to the panel support portion 9 in the height direction D6 can be changed.

[0058] The passenger conveyor 1, the passenger conveyor balustrade device 4, and the female screw material 12 are not limited to the configuration of the above-mentioned embodiment, and are not limited to the above-mentioned action and effect. Of course, the passenger conveyor 1, the passenger conveyor balustrade device 4, and the female screw material 12 can be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations and methods of the various modified examples described below and adopt them in the configurations and methods of the above-mentioned embodiment.

[0059] (A) In the passenger conveyor 1 according to the above embodiment, the female screw member 12 is configured to be attached to the hole 8e of the frame member 8. However, the passenger conveyor 1 is not limited to such a configuration.

[0060] For example, as shown in Fig. 8, the female threaded material 12 may be fixed to the panel support part 9 by a fixing means 14. In the configuration shown in Fig. 8, the male threaded material 13 is screwed into the female threaded portion 12a of the female threaded material 12 and inserted into a hole 8e of the frame material 8, and the upper end of the male threaded material 13 abuts against the panel 6 from below.

[0061] (B) In addition, in the passenger conveyor 1 according to the above embodiment, the lower end of the panel 6 is inserted into the frame recess 8a of the frame material 8, and the lower part of the frame material 8 is inserted into the support recess 9a of the panel support part 9. However, the passenger conveyor 1 is not limited to such a configuration.

[0062] For example, the balustrade device 4 may not include the frame material 8, and the lower end of the panel 6 may be directly inserted into the support recess 9a of the panel support part 9. In such a configuration, the female thread material 12 may be fixed to the panel support part 9, for example, or may be fixed to the structure 2, for example.

[0063] (C) In addition, in the passenger conveyor 1 according to the above embodiment, the female screw member 12 is configured to be detachable from the hole 8e of the frame member 8. However, the passenger conveyor 1 is not limited to such a configuration.

[0064] For example, as shown in Fig. 9, the female threaded material 12 may be fixed to the frame material 8 so as to be unable to come off from a hole 8e of the frame material 8. Although not particularly limited, in the configuration shown in Fig. 9, the female threaded material 12 may be fixed to the hole 8e of the frame material 8 by, for example, welding or adhesive. In addition, although not particularly limited, the female threaded material 12 shown in Fig. 9 may be, for example, a nut.

[0065] (D) In ​​addition, in the passenger conveyor 1 according to the above embodiment, the female screw material 12 is configured to include a base portion 12b that is accommodated in the bottom portion 8b of the frame recess 8a, and a protruding portion 12c that extends downward from the base portion 12b and protrudes downward from the hole 8e of the frame material 8 (located outside the frame recess 8a). However, the passenger conveyor 1 is not limited to this configuration.

[0066] For example, the female threaded member 12 may have a base portion 12b and may not have a protruding portion 12c. Also, for example, the entire female threaded member 12 may be disposed inside the frame recess 8a.

[0067] (E) In addition, in the passenger conveyor 1 according to the above embodiment, the length of the base portion 12b in the width direction D7 is longer than the distance between the pair of bottom sides 8c, 8c in the thickness direction D1. However, the passenger conveyor 1 is not limited to such a configuration.

[0068] For example, the length of the base portion 12b in the width direction D7 may be shorter than the distance in the thickness direction D1 between the pair of bottom side surfaces 8c, 8c. Also, for example, the length of the base portion 12b in the width direction D7 may be the same as the distance in the thickness direction D1 between the pair of bottom side surfaces 8c, 8c.

[0069] (F) In addition, in the passenger conveyor 1 according to the above embodiment, the distance between the pair of bottom sides 8c, 8c decreases toward the bottom, and the width of the base portion 12b in the thickness direction D1 decreases toward the bottom. However, the passenger conveyor 1 is not limited to such a configuration.

[0070] For example, the distance between the pair of bottom side surfaces 8c, 8c may be constant over the height direction D6, and the width of the base portion 12b in the thickness direction D1 may be constant over the height direction D6. Alternatively, the distance between the pair of bottom side surfaces 8c, 8c may be constant over the height direction D6, and the width of the base portion 12b in the thickness direction D1 may become smaller toward the bottom.

[0071] (G) In addition, in the passenger conveyor 1, for example, the hole 8e of the frame material 8 may be formed to a size that allows the base portion 12b of the female screw material 12 to pass through from below. In such a configuration, for example, as shown in Figure 10(a), the hole 8e may extend along the width direction D7.

[0072] As a result, first, one portion (left portion in FIG. 10) of the base portion 12b passes through the hole 8e as shown in FIG. 10(b), and then, the other portion (right portion in FIG. 10) of the base portion 12b passes through the hole 8e as shown in FIG. 10(c), so that the base portion 12b is disposed inside the frame recess 8a. Therefore, for example, after the lower end portion of the panel 6 is inserted into the frame recess 8a, the female screw material 12 can be fitted into the hole 8e of the frame material 8 from below the frame material 8.
