Detailed Implementation

[0027] The embodiments will now be described with reference to the accompanying drawings.

[0028] Implementation Method 1

[0029] Figure 1 This is a schematic structural diagram showing the escalator according to Embodiment 1. Figure 1 In this structure, truss 1 is erected between the upper and lower floors. Truss 1 supports multiple ladder steps 2. These ladder steps 2 are interconnected to form a ring. Figure 1 In the image, only four of the multiple rungs 2 are shown.

[0030] A pair of railing devices 3 and a pair of movable handrails 4 are provided on the truss 1. Figure 1 The image shows only one of a pair of railing devices 3 and one of a pair of movable handrails 4. Each movable handrail 4 is mounted on its corresponding railing device 3. Furthermore, each movable handrail 4 moves synchronously with multiple steps 2.

[0031] The moving path of the movable handrail 4 has a going route section, a returning route section, a lower-level turnaround section, and an upper-level turnaround section.

[0032] The outbound route section is the section where the user grasps the movable handrail 4. The return route section is the section where the movable handrail 4 moves in the opposite direction to the outbound route section; it is the section where the movable handrail 4 is not exposed to the outside. The lower-level return section is the section located between the outbound and return route sections at the lower level. The upper-level return section is the section located between the outbound and return route sections at the upper level.

[0033] The route section has a lower horizontal section A, a lower curved section B, a middle inclined section C, an upper curved section D, and an upper horizontal section E.

[0034] The lower horizontal section A is the horizontal section at the bottom. The upper horizontal section E is the horizontal section at the top. The middle inclined section C is the section that slopes at a fixed angle between the lower and upper sections. The lower curved section B is the curved section between the lower horizontal section A and the middle inclined section C. The upper curved section D is the curved section between the upper horizontal section E and the middle inclined section C.

[0035] Figure 2 It is along Figure 1 A sectional view along line II-II. Each railing assembly 3 has multiple railing panels 5, guardrails 6, multiple buffers 7, lighting devices 8, and multiple fasteners 9.

[0036] Multiple railing panels 5 are erected on the truss 1. Furthermore, the multiple railing panels 5 are arranged along the path of the movable handrail 4. Each railing panel 5 is made of transparent glass.

[0037] Guard rails 6 are installed on multiple railing panels 5. In the path section of the movable handrail 4, guard rails 6 are installed at the upper end of the railing panel 5. Furthermore, guard rails 6 guide the movement of the movable handrail 4. Moreover, guard rails 6 are constructed by splicing multiple segmented rails along the path section of the movable handrail 4.

[0038] Furthermore, the guardrail 6 has a handrail mounting portion 6a, a first protrusion 6b, and a second protrusion 6c. A movable handrail 4 is mounted on the handrail mounting portion 6a.

[0039] The first protrusion 6b and the second protrusion 6c protrude downwards from the handrail mounting portion 6a. The first protrusion 6b is positioned on the side opposite to the plurality of steps 2 relative to the handrail panel 5. That is, from the perspective of a user of the escalator, the first protrusion 6b is located on the outside of the handrail panel 5. The second protrusion 6c is positioned on the side of the plurality of steps 2 relative to the handrail panel 5.

[0040] An insertion groove 6d is formed between the first protrusion 6b and the second protrusion 6c of the guardrail 6. The upper ends of multiple rail panels 5 are inserted into the insertion groove 6d. Multiple buffer members 7 are clamped between the multiple rail panels 5 and the guardrail 6 within the insertion groove 6d.

[0041] The lighting device 8 is installed at the lower part of the guard rail 6. In addition, the lighting device 8 is continuously arranged along the travel section of the moving handrail 4.

[0042] Furthermore, the lighting device 8 includes a retaining member 11 and multiple lighting fixtures 12. The retaining member 11 is fixed to the lower end of the first protrusion 6b by means of multiple fasteners 9. Each fastener 9 is a screw. In addition, the retaining member 11 is constructed by splicing multiple segmented pieces along the travel section in the moving path of the movable handrail 4.

[0043] Each lighting fixture 12 is held by a holding member 11. In addition, each lighting fixture 12 has a substrate 13, a plurality of LED chips 14 and a resin cover 15.

[0044] Multiple LED chips 14 are mounted on a substrate 13. The substrate 13 and the multiple LED chips 14 are covered by a resin cover 15. The substrate 13 is integrated with the resin cover 15 during the molding process.

[0045] For example, silicone is used as the material for the resin cover 15. The material and thickness of the resin cover 15 are selected so that the user can directly view the lighting fixture 12 with the naked eye. As a result, the portion of the lighting fixture 12 that is lower than the holding member 11 does not need to be covered by other lighting covers and is exposed to the outside of the railing device 3.

[0046] The retaining member 11 has a flat top 11a and a retaining portion 11b. The top 11a is disposed below the first protrusion 6b and is fixed to the lower end of the first protrusion 6b by means of a plurality of fasteners 9. Furthermore, the top 11a contacts the lower surface of the first protrusion 6b.

[0047] A holding portion 11b protrudes downward from the top 11a to hold a plurality of lighting fixtures 12. In embodiment 1, the holding portion 11b has a pair of arms 11c. Each lighting fixture 12 is held by the pair of arms 11c.

[0048] Figure 3 It shows that Figure 2 The view shows the retaining member 11 before it is installed on the guard rail 6. When installing the lighting device 8 on the guard rail 6, the retaining member 11 is first installed on the first protrusion 6b. Then, a plurality of lighting fixtures 12 are installed on the retaining member 11.

[0049] A positioning groove 11d is provided on the lower surface of the top 11a, indicating the position through which multiple fasteners 9 pass.

[0050] Figure 4 From Figure 2 The side view shown is of the railing device 3 with the guardrail 6 removed, from... Figure 2 The diagram shows the railing device 3 viewed from the right. Multiple buffers 7 are intermittently spaced apart from each other in the direction of the moving section along the path of the movable handrail 4. Each railing panel 5 is transparent, but to make the positional relationship between each railing panel 5 and the lighting device 8 clear, [the following text is incomplete and likely refers to a different topic]... Figure 4 In the diagram, the portion of the lighting device 8 that overlaps with each railing panel 5 is shown by dashed lines.

[0051] In this escalator handrail assembly 3, an insertion groove 6d is formed between the first protrusion 6b and the second protrusion 6c of the guardrail 6. The upper end of the handrail panel 5 is inserted into the insertion groove 6d. Furthermore, the top 11a of the retaining member 11 is fixed to the lower end of the first protrusion 6b. The lighting fixture 12 is held by the retaining member 11. This allows for a more compact installation structure for the lighting device 8.

[0052] Furthermore, the structure of the guard rail 6 can be universalized regardless of the presence or absence of the lighting device 8 when shipped from the factory.

[0053] Furthermore, since a positioning groove 11d is provided on the top 11a, it is easy to carry out screwing operations or drilling operations on the installation site.

[0054] Furthermore, the material and thickness of the resin cover 15 are selected in a way that allows the user to directly view the lighting fixture 12 with the naked eye. Therefore, there is no need to use other lighting covers, which reduces the number of parts and prevents the railing device 3 from becoming too large.

[0055] Furthermore, multiple buffers 7 are intermittently arranged. Therefore, material costs can be reduced.

[0056] Alternatively, the positioning groove 11d can also be provided on the upper surface of the top 11a.

[0057] In addition, the retaining component 11 can also be attached to the lower end of the first protrusion 6b by means of double-sided tape, adhesive or magnet.

[0058] In addition, multiple buffers 7 can be continuously configured along the travel interval in the moving path of the moving handrail 4.

[0059] Implementation Method 2

[0060] Next, Figure 5 This is a cross-sectional view of the railing device 3 in Embodiment 2. Figure 6 Is only shown Figure 5 A cross-sectional view of the retaining component 11.

[0061] In addition to the top 11a and the holding portion 11b, the retaining member 11 of embodiment 2 also has a clamping portion 11e. The clamping portion 11e is clamped between the guard rail 6 and the plurality of railing panels 5 within the insertion slot 6d. The retaining member 11 is fixed to the guard rail 6 and the plurality of railing panels 5 by clamping the clamping portion 11e between the guard rail 6 and the plurality of railing panels 5.

[0062] The clamping part 11e has a first part 11f, a second part 11g, and a third part 11h. The first part 11f is located between the plurality of railing panels 5 and the first protrusion 6b. The second part 11g is located between the upper end face of the plurality of railing panels 5 and the bottom face of the insertion groove 6d. The third part 11h is located between the plurality of railing panels 5 and the second protrusion 6c.

[0063] The retaining member 11 is made of a material such as resin, so that the clamping part 11e functions as a buffer. Therefore, the buffer 7 is omitted. Furthermore, the positioning groove 11d is not provided on the top 11a of Embodiment 2.

[0064] Figure 7 From Figure 5 The side view shown is of the railing device 3 with the guardrail 6 removed, from... Figure 5The diagram shows the right-side observation of the railing device 3. The clamping part 11e is continuously formed along the path interval of the movable handrail 4.

[0065] Figure 8 It is shown Figure 7 A side view of a modified example of the retaining member 11. Figure 7 In the middle, multiple clamping parts 11e are intermittently formed along the moving path of the moving handrail 4.

[0066] Except for Figures 5-8 Apart from the structures described, the structure of the railing device 3 and the structure of the escalator are the same as in Embodiment 1.

[0067] In such a railing device 3 and lighting device 8, the retaining member 11 is fixed to the railing 6 and the multiple railing panels 5 by clamping the clamping part 11e between the railing 6 and the multiple railing panels 5. Therefore, the installation structure of the lighting device 8 can be made more compact.

[0068] In addition, it can reduce the effort required for screw installation on the installation site.

[0069] Furthermore, the structure of the guard rail 6 can be universalized regardless of the presence or absence of the lighting device 8 when shipped from the factory.

[0070] Furthermore, the clamping part 11e has a second part 11g and a third part 11h. Therefore, it is possible to more reliably prevent the lighting device 8 from detaching from the multiple railing panels 5.

[0071] Furthermore, since the clamping part 11e functions as a buffer, the number of parts can be reduced, and installation can be easily carried out.

[0072] In addition, in Embodiment 2, the same buffer 7 as in Embodiment 1 may be used in addition to the clamping part 11e.

[0073] Implementation Method 3

[0074] Next, Figure 9 This is a cross-sectional view of the railing device 3 according to embodiment 3. Figure 10 Is only shown Figure 9 A cross-sectional view of the retaining member 11. Multiple clamping portions 11e are intermittently formed along the travel section of the moving handrail 4. Furthermore, buffer members 7 are respectively arranged between adjacent clamping portions 11e. Each clamping portion 11e has only a first part 11f and a second part 11g.

[0075] The retaining component 11 is fixed to the guard rail 6 and the multiple rail panels 5 by clamping the clamping part 11e between the guard rail 6 and the multiple rail panels 5.

[0076] Except for the structure of component 11, the structure of the railing device 3 and the structure of the escalator are the same as in embodiment 1.

[0077] This structure also allows for a more compact installation of the lighting device 8. Furthermore, it eliminates the need for on-site screw installation. Additionally, the structure of the guard rail 6 shipped from the factory can be standardized regardless of the presence or absence of the lighting device 8.

[0078] Furthermore, by hanging the second part 11g on the upper surface of each railing panel 5, it is possible to prevent the lighting device 8 from detaching from the multiple railing panels 5.

[0079] Implementation Method 4

[0080] Next, Figure 11 This is a cross-sectional view of the railing device 3 in embodiment 4. Figure 12 Is only shown Figure 11 A cross-sectional view of the retaining member 11. Each clamping part 11e in Embodiment 4 has only the first part 11f.

[0081] The retaining component 11 is fixed to the guard rail 6 and the multiple rail panels 5 by clamping the clamping part 11e between the guard rail 6 and the multiple rail panels 5.

[0082] Except for the structure of component 11, the structure of the railing device 3 and the structure of the escalator are the same as those in embodiment 3.

[0083] This structure also allows for a more compact installation of the lighting device 8. Furthermore, it eliminates the need for on-site screw installation. Additionally, the structure of the guard rail 6 shipped from the factory can be standardized regardless of the presence or absence of the lighting device 8.

[0084] In addition, in embodiments 3 and 4, each clamping part 11e may also function as a buffer.

[0085] Furthermore, in embodiments 3 and 4, multiple buffer components 7 may be omitted.

[0086] Alternatively, the clamping part 11e of Embodiment 2, Embodiment 3 or Embodiment 4 may be provided on the holding member 11 of Embodiment 1.

[0087] Implementation Method 5

[0088] Next, Figure 13 This is a cross-sectional view of the lighting device 8 according to Embodiment 5. In addition to having the same structure as in Embodiment 2, the retaining member 11 of Embodiment 5 also has a stop portion 11i. The stop portion 11i protrudes downward from the top 11a. Furthermore, the stop portion 11i restricts the movement of the lighting fixture 12 towards the top 11a.

[0089] A stop 11i ensures a space 20 between the top 11a and the lighting fixture 12. Multiple wirings 16 are arranged in the space 20. The multiple wirings 16 are connected to the lighting fixture 12.

[0090] Except for the structure of component 11, the structure of the railing device 3 and the structure of the escalator are the same as in embodiment 1.

[0091] This structure also allows for a more compact installation of the lighting device 8. Furthermore, it eliminates the need for on-site screw installation. Additionally, the structure of the guard rail 6 shipped from the factory can be standardized regardless of the presence or absence of the lighting device 8.

[0092] Furthermore, since the stop portion 11i protrudes from the top 11a, space 20 can be ensured between the top 11a and the lighting fixture 12. As a result, multiple wiring 16 can be configured efficiently.

[0093] Furthermore, the lighting fixture 12 can be easily positioned vertically, and multiple wiring 16 can be easily configured, which can improve the efficiency of the installation work.

[0094] In addition, multiple wiring 16 can be configured in a way that is not conspicuous from the outside, which can improve the appearance.

[0095] Alternatively, the same stop portion 11i as in Embodiment 5 can be provided on the retaining member 11 that does not have a clamping portion 11e, as in Embodiment 1. When the retaining member 11 in Embodiment 1 is provided with a stop portion 11i, space for accommodating multiple fasteners 9 can be ensured between the top 11a and the lighting fixture 12, and interference between the multiple fasteners 9 and the lighting fixture 12 can be avoided.

[0096] Furthermore, in embodiments 1 to 5, the lighting fixture 12 can also be held in the holding part 11b by means of double-sided tape, adhesive or magnet.

[0097] Furthermore, in embodiments 1 to 5, the material of the railing panel 5 is not limited to glass; for example, it may also be resin.

[0098] Furthermore, in embodiments 1 to 5, the lighting device 8 may be installed on only one of the pair of railing devices 3, or it may be installed on both of the pair of railing devices 3.

[0099] Furthermore, in embodiments 1 to 5, the lighting device 8 can be continuously installed throughout the entire travel section of the moving handrail 4, or it can be installed intermittently.

[0100] Furthermore, in embodiments 1 to 5, the lighting device 8 may also be installed only in a portion of the travel section of the moving handrail 4.

[0101] In addition, passenger conveyors can also be passenger conveyors other than escalators, such as moving walkways.
