[0019] The embodiments are described below with reference to the accompanying drawings.

[0020] Implementation Method 1

[0021] Figure 1 This is a perspective view showing the main parts of the escalator according to Embodiment 1. In the figure, the annular conveyor 1 transports users in a loop. Furthermore, the conveyor 1 has multiple steps 2. The multiple steps 2 are connected in a loop.

[0022] The circulation path of conveyor 1 includes a outbound section, a return section, an upper-level turnaround section, and a lower-level turnaround section. The outbound section is where the user is transported. The return section is located below the outbound section. The upper-level turnaround section connects the outbound and return sections at the upper level. The lower-level turnaround section connects the outbound and return sections at the lower level.

[0023] The path section has a lower horizontal section, a lower curved section, a middle inclined section, an upper curved section, and an upper horizontal section. The lower curved section is the part between the lower horizontal section and the middle inclined section. The upper curved section is the part between the upper horizontal section and the middle inclined section.

[0024] A pair of railings 3 are installed on both sides of the conveyor body 1 in the width direction of the outgoing section. Figure 1 The image shows only one of a pair of railings 3. Each railing 3 is equipped with a ring-shaped movable handrail 4. The movable handrail 4 circulates synchronously with the conveyor body 1.

[0025] Figure 2 It is along Figure 1 A sectional view along line II-II. A truss 5 is erected between the upper and lower floors of the building. A conveyor body 1 is housed within the truss 5. Furthermore, the conveyor body 1 is supported by the truss 5. A pair of railings 3 stand on the truss 5.

[0026] Truss 5 has multiple upper chords 6, multiple lower chords (not shown), multiple longitudinal members 7, multiple inclined members (not shown), multiple upper transverse members (not shown), and multiple lower transverse members (not shown).

[0027] Each lower chord is positioned below its corresponding upper chord 6. Each longitudinal member 7 is fixed between its corresponding upper chord 6 and its corresponding lower chord. Each inclined member is fixed between its corresponding upper chord 6 and its corresponding lower chord. Furthermore, each inclined member is inclined relative to its adjacent longitudinal member.

[0028] Each upper transverse member is fixed between adjacent upper chords 6 in the width direction of truss 5. Each lower transverse member is fixed between adjacent lower chords in the width direction of truss 5. The width direction of truss 5 is... Figure 2 The left and right directions.

[0029] Each railing 3 has a railing panel 8, an inner cover plate 9, an outer cover plate 10, and a skirt board 11.

[0030] In each railing 3, the inner cover plate 9 and the outer cover plate 10 are disposed at the lower part of the railing panel 8. In each railing 3, the inner cover plate 9 is disposed on the side of the conveyor body 1 relative to the railing panel 8. In each railing 3, the outer cover plate 10 is disposed on the side opposite to the conveyor body 1 relative to the railing panel 8.

[0031] In each railing 3, a skirt panel 11 is provided at the lower part of the inner cover plate 9. In addition, in each railing 3, the skirt panel 11 is arranged on the side of the conveyor body 1 with a gap 30. That is, each skirt panel 11 is opposite to the side of the plurality of steps 2 located in the destination section of the conveyor body 1.

[0032] In each railing 3, the inner cover plate 9 closes the opening between the lower end of the railing panel 8 and the upper end of the skirt panel 11.

[0033] Each apron panel 11 is composed of multiple partition plates. The multiple partition plates are arranged continuously along the path section of the conveyor body 1. In addition, each apron panel 11 is made of metal, such as stainless steel.

[0034] The escalator is equipped with multiple skirt panel switching devices 12. Each skirt panel switching device 12 is disposed between the longitudinal member 7 and the skirt panel 11. In addition, in Embodiment 1, the multiple skirt panel switching devices 12 are respectively disposed in the lower bend and upper bend of the outgoing section of the circulation path of the conveyor body 1.

[0035] Figure 3 It is along Figure 2 A sectional view along line III-III. The apron switch device 12 has a flat connecting part 21, a bracket 22, multiple fixing bolts 23, a detection switch 24, a fixing plate 25, a movable plate 26, an adjusting bolt 27, and a nut 28.

[0036] The connecting component 21 is fixed to the longitudinal component 7, for example, by welding. In addition, the connecting component 21 protrudes horizontally from the longitudinal component 7 toward the conveyor body 1.

[0037] The bracket 22 is fixed to the connecting member 21 by a plurality of fixing bolts 23. That is, the bracket 22 is fixed relative to the truss 5 by the connecting member 21. In addition, the bracket 22 is disposed between the conveyor body 1 and the longitudinal member 7.

[0038] The bracket 22, when fixed to the connecting member 21, has a U-shaped planar shape. The bracket 22 has a first opposing portion 22a, a second opposing portion 22b, and a connecting portion 22c. The first opposing portion 22a, the second opposing portion 22b, and the connecting portion 22c are formed by bending a rectangular flat plate. The bracket 22 is made of the same metal as the apron panel 11, such as stainless steel.

[0039] The shapes of the first opposing portion 22a, the second opposing portion 22b, and the connecting portion 22c are all rectangular flat plates. The first opposing portion 22a and the second opposing portion 22b protrude horizontally from the connecting portion 22c in the same direction. Thus, the first opposing portion 22a and the second opposing portion 22b are opposite each other. Furthermore, the first opposing portion 22a and the second opposing portion 22b are parallel to each other and form a right angle with respect to the connecting portion 22c.

[0040] The first opposing portion 22a has an opposing surface 22d and an outer surface 22e. The opposing surface 22d is the surface opposite to the second opposing portion 22b. The outer surface 22e is the surface opposite to the opposing surface 22d.

[0041] The outer surface 22e contacts the apron panel 11. The apron panel 11 is fixed to the outer surface 22e, for example, by adhesive or welding. That is, the first opposing portion 22a is overlapped and fixed to the apron panel 11. In addition, the first opposing portion 22a can be deformed integrally with the apron panel 11.

[0042] The connecting part 22c connects the first opposing part 22a and the second opposing part 22b. Furthermore, the connecting part 22c is fixed to the connecting member 21 by a plurality of fixing bolts 23. Thus, the connecting part 22c is fixed relative to the truss 5.

[0043] An elongated hole (not shown) is provided in the connecting member 21 or the connecting part 22c. Multiple fixing bolts 23 pass through the elongated hole. Therefore, the position of the connecting part 22c relative to the connecting member 21 can be adjusted in the width direction of the conveyor body 1 by loosening the multiple fixing bolts 23.

[0044] The detection switch 24 is supported on the bracket 22. In addition, the detection switch 24 detects the deformation of the skirt plate 11 in the direction away from the conveyor body 1.

[0045] Furthermore, the detection switch 24 has a switch body 24a and an operating part 24b. The base end of the switch body 24a is fixed to the first opposing part 22a. The operating part 24b is provided at the front end of the switch body 24a. In addition, the operating part 24b is opposite to the second opposing part 22b.

[0046] The detection switch 24 is operated by the second opposing part 22b through the deformation of the apron plate 11.

[0047] For example, such as Figure 4 As shown, when the foreign object 31 is trapped between the step 2 and the skirt board 11, the skirt board 11 flexes away from the conveyor body 1. At this time, the first opposing part 22a flexes integrally with the skirt board 11.

[0048] In contrast, since the connecting part 22c is fixed to the connecting member 21, the second opposing part 22b will not move or deform. Therefore, when the first opposing part 22a flexes, the detection switch 24 fixed to the first opposing part 22a approaches the second opposing part 22b. Then, when the amount of flexure of the first opposing part 22a exceeds a set value, the operating part 24b is operated by the second opposing part 22b.

[0049] The fixed piece 25 is fixed to the connecting member 21. The movable piece 26 is fixed to the connecting part 22c. In addition, the movable piece 26 is opposite to the fixed piece 25.

[0050] Adjusting bolt 27 passes through fixed plate 25 from the side opposite to movable plate 26 and is screwed into movable plate 26. That is, adjusting bolt 27 is provided between connecting member 21 and bracket 22 through fixed plate 25 and movable plate 26.

[0051] The fixed plate 25 has a through hole 25a for the adjusting bolt 27 to pass through. The movable plate 26 has a threaded hole 26a for the adjusting bolt 27 to be screwed in. The nut 28 and the end face of the fixed plate 25 opposite to the movable plate 26 are in contact. The adjusting bolt 27 is screwed into the nut 28.

[0052] With the multiple fixing bolts 23 loosened, the position of the connecting part 22c relative to the connecting component 21 in the width direction of the conveyor body 1 is adjusted by rotating the adjusting bolt 27.

[0053] In this escalator and skirt panel switching device 12, the first opposing portion 22a is overlapped and fixed to the skirt panel 11, and can deform integrally with the skirt panel 11. The second opposing portion 22b is opposite to the first opposing portion 22a. In addition, the connecting portion 22c is fixed relative to the truss 5. Furthermore, the detection switch 24 is provided at the first opposing portion 22a, and is operated by the second opposing portion 22b by the deformation of the skirt panel 11.

[0054] Therefore, it is not necessary to perform hole machining on the apron 11 to allow the movable piece to pass through, thus preventing the structure of the apron 11 from becoming complicated.

[0055] In addition, the bracket 22 can be pre-fixed to the skirt board 11 in the factory, which can improve the workability during the installation of the escalator.

[0056] In addition, there is no need to adjust the gap between the detection switch 24 and the second opposing part 22b on site, making on-site adjustment work easy.

[0057] In addition, since the head of the screw does not protrude from the apron 11 toward the conveyor body 1, foreign objects will not get caught on the head of the screw.

[0058] Furthermore, the position of the connecting part 22c relative to the connecting component 21 can be adjusted in the width direction of the conveyor body 1 by loosening the plurality of fixing bolts 23. Therefore, the gap between the skirt plate 11 and the conveyor body 1 can be easily adjusted.

[0059] In addition, an adjusting bolt 27 is provided between the connecting part 21 and the bracket 22, so that the gap between the skirt plate 11 and the conveyor body 1 can be adjusted more easily.

[0060] Alternatively, the detection switch 24 can also be provided in the second opposing part 22b. In this case, the detection switch 24 is operated by the first opposing part 22a.

[0061] In addition, the location of the apron board switch device 12 is not limited to the lower curved part and the upper curved part, but may also be the middle inclined part.

[0062] In addition, there is no particular limitation on the number of apron board switch devices 12.

[0063] Alternatively, passenger conveyors can also be moving walkways.
