[0001] SUMMARY OF THE DISCLOSURE Embodiments of the present invention relate to a passenger conveyor and a method for manufacturing a passenger conveyor. [Background technology]

[0002] A known installation form of a passenger conveyor is one in which a plurality of passenger conveyor bodies are arranged side by side in the left-right direction. In a passenger conveyor having such an installation form, a guide fence is provided between the boarding and alighting doors of the passenger conveyor bodies adjacent in the left-right direction in order to safely guide passengers to the passenger conveyor body.

[0003] The guide fence is fixed by welding the legs to the top surface of the upper frame material at the top of the truss of the passenger conveyor body. Therefore, it is difficult to replace the guide fence, and in some cases, welding work cannot be done during modification work of an existing passenger conveyor, making it impossible to install the guide fence.

[0004] In addition, the installation work of the guide fence can be made easier by fixing it to the boarding and alighting board located between the boarding and alighting doors of adjacent passenger conveyor bodies in the left-right direction; however, if a user leans on it and applies force to the guide fence, the board may be damaged or deformed.

A pair of left and right drive sprockets 7 are rotated by this drive chain 8. The pair of left and right drive sprockets 7 and the pair of left and right handrail belt sprockets are connected by a connecting belt (not shown) and rotate synchronously.

[0019] A pair of left and right driven sprockets 10 are provided inside the lower floor machine room 9 at the bottom end of the truss 2. A pair of left and right endless step chains 11 are stretched between the driving sprocket 7 on the upper floor and the driven sprocket 10 on the lower floor. A pair of left and right balustrades 13 are provided on the top of the truss 2. A handrail belt 15 that moves in sync with the steps 30 is provided on the balustrades 13.

[0020] 1, at the upper floor entrance 17L, a boarding / alighting plate 19L is provided horizontally so as to cover the upper surface of the machine room 5, and a comb having multiple comb teeth protruding at equal intervals is provided at the tip of the boarding / alighting plate 19L. At the lower floor entrance 18, a boarding / alighting plate 20 is provided horizontally so as to cover the upper surface of the machine room 9, and a comb having multiple comb teeth protruding at equal intervals is provided at the tip of the boarding / alighting plate 20.

[0021] The passenger conveyor body 1R installed on the right side has a similar configuration to the passenger conveyor body 1L installed on the left side described above.

[0022] As shown in Figures 2 and 3, the left-hand passenger conveyor main body 1L and the right-hand passenger conveyor main body 1R have upper floor entrances 17L, 17R arranged side by side in the left-right direction. Between the upper floor entrances 17L, 17R, an upper frame facing part 40 is formed in which an upper frame member 21L of the left-hand passenger conveyor main body 1L and an upper frame member 21R of the right-hand passenger conveyor main body 1R face each other with a gap S in the left-right direction. A receiving stand 50 is removably attached to the upper frame facing part 40, and a guide fence 70 is fixed to the receiving stand 50.

[0023] Between the boarding and alighting board 19L provided at the boarding and alighting entrance 17L of the left passenger conveyor main body 1L and the boarding and alighting board 19R provided at the boarding and alighting entrance 17R of the right passenger conveyor main body 1R, an intermediate boarding and alighting board 19M is provided to cover the upper part of the upper frame facing part 40. A guide fence 70 is provided on the upper surface of the intermediate boarding and alighting board 19M. The guide fence 70 is fixed to a metal receiving base 50 that is detachably attached to the upper frame facing part 40. The intermediate boarding and alighting board 19M is formed so as not to have any step with the surfaces of the boarding and alighting boards 19L, 19R provided on both the left and right sides thereof, and is configured to have a substantially uniform planar shape.

[0024] (2) Upper frame opposing portion 40 As shown in Figure 4, the upper frame opposing portion 40 comprises an upper frame member 21L of the left-side passenger conveyor main body 1L arranged at the boarding / alighting entrance 17L, an upper frame member 21R of the right-side passenger conveyor main body 1R arranged at the boarding / alighting entrance 17R, and a gap S extending in the fore-and-aft direction formed between the upper frame members 21L and 21R.

[0025] The upper frame member 21L is a member extending in the front-rear direction and having an upper surface portion 21L1 having a horizontal surface and a side surface portion 21L2 extending downward from a side end portion of the upper surface portion 21L1. The upper surface portion 21L1 is provided with a boarding / disembarking board support portion 41L.

[0026] The boarding / alighting plate support portion 41L is, for example, a cylindrical body extending in the front-rear direction formed by bending a metal plate. The boarding / alighting plate 19L and the intermediate boarding / alighting plate 19M are placed on the upper surface of the boarding / alighting plate support portion 41L. The boarding / alighting plate support portion 41L is disposed on a pedestal 42L provided on the upper surface portion 21L1 of the upper frame material 21L with a gap therebetween above the upper surface portion 21L1, and is fixed to the upper frame material 21L by fasteners 43L such as bolts.

[0027] The upper frame member 21R of the right passenger conveyor main body 1R is a member extending in the front-rear direction, similar to the upper frame member 21L, and having an upper surface portion 21R1 and a side surface portion 21R2. A board support portion 41R is provided on the upper surface of the board support portion 41R, and the board 19R and the intermediate board 19M are placed on the upper surface of the board support portion 41R.

[0028] Like the boarding and alighting board support part 41L, the boarding and alighting board support part 41R is composed of a cylindrical body extending in the front-to-rear direction formed by bending a metal plate, and is positioned above and spaced apart from the upper surface part 21R1 on a base 42R provided on the upper surface part 21R1 of the upper frame material 21R, and is fixed to the upper frame material 21R by a fastener 43R such as a bolt.

[0029] (3) Receiving stand 50 As shown in Figures 4 to 6, the receiving base 50 comprises a metal upper member 51 provided on the upper side of the upper surface portions 21L1, 21R1 of the upper frame members 21L, 21R and on the upper side of the gap S, lower members 52, 52 provided respectively at the front and rear portions of the lower side of the side portions 21L2, 21R2 of the upper frame members 21L, 21R, and connecting members 53, 53 that pass through the gap S to connect the upper member 51 and the lower member 52.

[0030] The upper member 51 includes a flat upper fixing portion 51a extending across the upper surface portions 21L1, 21R1 of the left and right upper frame members 21L, 21R, and a protrusion 51b provided in the center of the upper fixing portion 51a in the front-rear direction.

[0031] The upper fixing portion 51a is provided with a hole 51c through which the connecting member 53 is inserted. In this embodiment, one hole 51c is provided on each of the front and rear sides of the protruding portion 51b, penetrating the upper fixing portion 51a in the up-down direction. Note that the hole 51c may be a circular hole with a closed periphery, or may be a slit-like hole that opens at the front end or rear end of the upper fixing portion 51a.

[0032] The protruding portion 51b protrudes upward from the upper fixing portion 51a, and a flat mounting portion 51d is formed at the top. The mounting portion 51d supports the intermediate board 19M by placing the intermediate board 19M thereon. The mounting portion 51d is also provided with a female screw portion 51e that screws into a bolt 71 that fixes the guide fence 70, as shown in FIG.

[0033] In addition, one or more adjustment plates 54 may be provided between the upper fixing portion 51a and the upper surface portions 21L1, 21R1 of the left and right upper frame members 21L, 21R so that the upper surface of the mounting portion 51d and the upper surfaces of the boarding and alighting board support portions 41R, 41L are at the same height.

[0034] The lower member 52 includes a lower metal fixing portion 52a that abuts against the lower ends of the side portions 21L2, 21R2 of the upper frame members 21L, 21R, and a metal or rubber rotation restricting portion 52b that protrudes upward from the lower fixing portion 52a.

[0035] The lower fixing portion 52a has a length in the left-right direction longer than the gap S, and is provided so as to bridge the lower ends of the side surface portions 21L2 and 21R2 from left to right.

[0036] The rotation restricting portion 52b is provided such that its length in the left-right direction is shorter than the gap S. The rotation restricting portion 52b fits into the gap S from below, and restricts the lower fixing portion 52a from rotating around the connecting member 53 during attachment.

[0037] The connecting member 53 is made of a metallic shaft-shaped member protruding upward from the lower member 52, with its lower end fixed to the lower member 52 and its upper end provided with a male screw portion 53a. The male screw portion 53a of the connecting member 53 is inserted into a hole portion 51c of the upper member 51 and is screwed into a nut 55 on the upper side of the upper fixing portion 51a.

[0038] The method of mounting such a receiving stand 50 involves providing an upper member 51 on the upper side of the upper frame members 21L, 21R, providing a lower member 52 on the lower side of the upper frame members 21L, 21R, inserting a connecting member 53 protruding upward from the lower member 52 into a hole 51c in the upper member, and then screwing a nut 55 into the male threaded portion 53a. As a result, the upper fixing portion 51a of the upper member 51 and the lower fixing portion 52a of the lower member 52 sandwich the upper frame members 21L, 21R from above and below, and the receiving stand 50 can be fixed to the upper frame opposing portion 40.

[0039] (4) Guide fence 70 1 to 3 and 6, the guide fence 70 has a horizontal section 70a made of a bent metal pipe extending in the front-rear direction, and legs 70b, 70b provided at the front and rear ends of the horizontal section 70a. A fixing plate having a rectangular planar shape is provided at the lower end of the front leg 70b, and this fixing plate is provided on the intermediate boarding and alighting plate 19M. Before the installation of the guide fence 70, the fixing plate is fixed with bolts 71 to the female threaded section 51e of the receiving stand 50 that has been attached to the upper frame members 21L and 21R, sandwiching the intermediate boarding and alighting plate 19M therebetween.

[0040] The rear leg 70b is fixed to the floor of the building by an anchor bolt (not shown).

[0041] Although the rear leg 70b is fixed to the floor of the building here, it may be provided on the intermediate board 19M and fixed to the support pedestal 50, similar to the front leg 70b.

[0042] (5) Effects In the passenger conveyor 1 of this embodiment, the guide fence 70 is fixed to a removable support base 50 on the upper frame opposing portion 40 consisting of the upper frame materials 21L and 21R, so that the guide fence 70 can be installed without the need for welding work, and the guide fence 70 can also be easily removed and easily installed again.

[0043] In addition, by fixing the receiving base 50 to the upper frame members 21L, 21R, the force acting from the guide fence 70 on the boarding and alighting board 20M can be reduced. In particular, even if a passenger leans against the guide fence 70 and generates a force lifting it upward, the lower fixing portion 52a is provided to span the lower ends of the side portions 21L2, 21R2 of the upper frame members 21L, 21R from left to right, so strength can be maintained and the guide fence 70 will not tilt, preventing damage and deformation of the boarding and alighting board 20M.

[0044] In addition, the guide fence 70 and the receiving base 50 can be easily attached and detached, and the receiving base 50 and the upper frame members 21L and 21R can also be attached and detached.

[0045] Furthermore, the guide fence 70 may be installed not only during modification work of an existing passenger conveyor 1, but also during construction work of a new passenger conveyor 1.

[0046] In addition, by using an adjustment plate 54 between the receiving base 50 and the upper frame materials 21L, 21R, the height of the mounting portion 51d of the receiving base 50 and the upper surface of the board support portion 41R, 41L can be easily made the same height, and the boards 19L, 19R and the intermediate board 19M can be installed at the boarding and alighting openings 17L, 17R without any steps.

[0047] Furthermore, the lower member 52 of the receiving base 50 is provided with a rotation restricting portion 52b that fits into the gap S formed between the upper frame members 21L, 21R and restricts the lower member 52 from rotating around the connecting member 53. Therefore, when the nut 55 is screwed into the male thread portion 53a of the connecting member 53, the connecting member 53 does not rotate, and the receiving base 50 can be reliably attached to the upper frame members 21L, 21R.

[0048] (6) Example of changes Modifications of the above-described embodiment will be described. Any one of the multiple modification examples described below may be applied to the above-described embodiment, or any two or more of the modification examples described below may be applied in combination. In addition to the following modification examples, various modifications are possible.

[0049] (6-1) Change example 1 In the embodiment described above, one hole 51c is provided on each of the front and rear sides of the protrusion 51b of the receiving base 50, and the protrusion 51b is connected to the lower member 52 by a connecting member 53. However, as illustrated in Figure 7, multiple holes 51c (two on the front and two on the rear sides in Figure 7) may be provided on each of the front and rear sides of the protrusion 51b, and the protrusion 51b may be connected to the lower member 52 by multiple connecting members 53.

[0050] (6-2) Change example 2 In the above-described embodiment, the receiving base 50 was fixed to the upper frame opposing portion 40 by sandwiching the upper frame materials 21L, 21R between the upper member 51 and the lower member 52 from above and below, but the receiving base 50 may also be fixed to the upper frame opposing portion 40 by fixing the receiving base 50 to the upper frame connecting members 60A, 60B provided on the upper side of the upper frame materials 21L, 21R.

[0051] Specifically, as shown in Figures 8 to 10, the upper frame connecting members 60A, 60B are made of metal plate members having a rectangular planar shape that are arranged on the upper side of the upper frame members 21L, 21R to span the gap S to connect the left and right upper frame members 21L, 21R, and are composed of a front upper frame connecting member 60A provided on the front side of the receiving base 50, and a rear upper frame connecting member 60B provided on the rear side of the receiving base 50.

[0052] The upper frame connecting members 60A, 60B are provided with through holes 61AL, 61AR, 61BL, 61BR that penetrate in the up-down direction at both left and right ends, respectively, and have female screw portions 62A, 62B provided in the left-right center.

[0053] The through hole 61AL provided on the left side of the front upper frame connecting member 60A consists of a slit-shaped hole that opens to one of the front and rear ends (e.g., the front end) of the upper frame connecting member 60A, and the through hole 61AR provided on the right side of the upper frame connecting member 60A consists of a slit-shaped hole that opens to the other of the front and rear ends (e.g., the rear end) of the upper frame connecting member 60A. In other words, the through hole 61AR of the upper frame connecting member 60A consists of a slit-shaped hole that opens to the front-rear opposite side to the through hole 61AL.

[0054] Furthermore, the through hole 61BL provided on the left side of the rear upper frame connecting member 60B is a slit-shaped hole that opens to one of the front and rear ends (e.g., the rear end) of the upper frame connecting member 60B, and the through hole 61BR provided on the right side of the upper frame connecting member 60B is a slit-shaped hole that opens to the other of the front and rear ends (e.g., the front end) of the upper frame connecting member 60B. In other words, the through hole 61BR of the upper frame connecting member 60B is a slit-shaped hole that opens to the front-rear opposite side to the through hole 61BL.

[0055] Furthermore, as shown in Figure 10, it is preferable that the through holes 61BL, 61BR provided in the rear upper frame connecting member 60B are slit-shaped holes that open in the opposite direction from the through holes 61BL, 61BR provided in the front upper frame connecting member 60A.

[0056] In other words, the through hole 61BL provided on the left side of the rear upper frame connecting member 60B is a slit-shaped hole that opens on the opposite side (e.g., the rear end) from the through hole 61AL provided on the left side of the front upper frame connecting member 60A, and the through hole 61BR provided on the right side of the rear upper frame connecting member 60B is a slit-shaped hole that opens on the opposite side (e.g., the front end) from the through hole 61AR provided on the right side of the front upper frame connecting member 60A.

[0057] The protrusion 43L extending in the vertical direction provided on the boarding / alighting board support part 41L of the left passenger conveyor main body 1L is inserted into the through holes 61AL, 61BL provided on the left side of the upper frame connecting members 60A, 60B. The protrusion 43R extending in the vertical direction provided on the boarding / alighting board support part 41R of the right passenger conveyor main body 1R is inserted into the through holes 61AR, 61BR provided on the right side of the upper frame connecting members 60A, 60B. By inserting the protrusions 43L, 43R into the through holes 61AL, 61AR, 61BL, 61BR, the movement of the upper frame connecting members 60A, 60B in the front-rear and left-right directions is restricted.

[0058] In this modified example, to attach the receiving base 50 to the upper frame opposing portion 40, first, the upper frame connecting members 60A, 60B are rotated around the vertical axis while the protrusions 43L, 43R are inserted into the through holes 61AL, 61AR, 61BL, 61BR, and the upper frame connecting members 60A, 60B are positioned so as to connect the upper surface portions 21L1, 21R1 of the left and right upper frame members 21L, 21R.

[0059] Then, a bolt 63 passing through a hole 51c provided in the upper fixing portion 51a of the receiving base 50 is screwed into the female threaded portions 62A, 62B of the upper frame connecting members 60A, 60B provided on the upper surface portions 21L1, 21R1 of the upper frame materials 21L, 21R to fix the receiving base 50 to the upper frame connecting members 60A, 60B.

[0060] In addition, in this modified example, one or more adjustment plates 64 may be provided between the upper fixing portion 51a of the upper member 51 and the upper frame connecting members 60A, 60B so that the upper surface of the mounting portion 51d and the upper surfaces of the boarding and alighting board support portions 41R, 41L are at the same height.

[0061] In this modified example, the receiving base 50 can be fixed by the upper frame connecting members 60A, 60B arranged on the upper side of the upper surface portions 21L1, 21R1 without placing any members on the lower side of the side portions 21L2, 21R2 of the upper frame materials 21L, 21R, making the installation work of the receiving base 50 even easier.

[0062] In addition, since the through holes 61AL, 61BL provided at the left ends of the upper frame connecting members 60A, 60B and the through holes 61AR, 61BR provided at the right ends open on opposite sides to each other in the front-to-back direction, the upper frame connecting members 60A, 60B can be prevented from shifting in the front-to-back direction.

[0063] The protrusions 43L, 43R to be inserted into the through holes 61AL, 61AR, 61BL, 61BR of the upper frame connecting members 60A, 60B may be any members extending in the vertical direction provided on the boarding / disembarking board support portion 41. For example, as shown in Fig. 9, the fasteners 43L, 43R that fix the boarding / disembarking board support portions 41L, 41R to the upper surface portions 21L1, 21R1 of the upper frame members 21L, 21R may serve as protrusions and be inserted into the through holes 61AL, 61AR, 61BL, 61BR.

[0064] (6-3) Change example 3 In the above-described embodiment, the legs 70b of the guide fence 70 are directly fixed to the protrusions 51b of the receiving base 50 by bolts 71.
