Detailed Implementation

[0021] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In the drawings, identical or equivalent parts are labeled with the same reference numerals, and repeated descriptions are appropriately simplified or omitted. Furthermore, the present disclosure is not limited to the following embodiments; any modifications or omissions of any constituent elements of the embodiments are permitted without departing from the spirit of the present disclosure.

[0022] Implementation method 1.

[0023] Figure 1 This is a side view of an escalator as an embodiment 1 of a passenger conveyor. In the figure, a truss 101 is provided between the upper and lower levels. One end of the truss 101 along its length serves as the upper end of the truss 101 and is attached to the upper level structure. The other end of the truss 101 along its length serves as the lower end of the truss 101 and is attached to the lower level structure. The width direction of the truss 101 coincides with the horizontal direction perpendicular to the length direction of the truss 101.

[0024] An upper machine room is provided inside the upper end of truss 101. A lower machine room is provided inside the lower end of truss 101. An upper sprocket 102, a drive motor (not shown), and a conveyor control device described later are provided in the upper machine room. A lower sprocket 103 is provided in the lower machine room.

[0025] The truss 101 supports multiple steps 104 for passengers to ride on. The multiple steps 104 are connected in a loop by step chains 105. The step chains 105 are wound around the upper sprocket 102 and the lower sprocket 103.

[0026] The drive motor generates a driving force that causes each step 104 to move cyclically. The conveyor control device controls the operation of the escalator. The drive motor is controlled by the conveyor control device. The upper sprocket 102 rotates under the driving force of the drive motor. Each step 104 moves cyclically between the upper and lower machine compartments by the rotation of the upper sprocket 102.

[0027] A pair of railing devices 1 are provided on the truss 101, facing each other in the width direction of the truss 101. A ring-shaped movable handrail 106 is provided on the periphery of each railing device 1. Each movable handrail 106 moves synchronously with each step 104 on the periphery of each railing device 1 by the driving force of a drive motor.

[0028] Figure 2 It is along Figure 1 A sectional view along line II-II. Each railing assembly 1 has a railing panel 2, a cover plate assembly 3, an inner lighting device 4, and an outer lighting device 5. The inner lighting device 4 and the outer lighting device 5 are included as a pair of lighting devices in each railing assembly 1.

[0029] The railing panel 2 is a transparent glass panel that is erected on the truss 101. The railing panel 2 is arranged along the length of the truss 101. The lower part of the railing panel 2 is held by a panel holding part (not shown) that is fixed to the truss 101.

[0030] The cover plate device 3 is disposed on the lower part of the railing panel 2. The cover plate device 3 covers the space around the lower part of the railing panel 2. The panel retaining part of the lower part of the railing panel 2 is covered by the cover plate device 3.

[0031] The cover plate device 3 has a skirt plate 31, an inner cover plate 32, and an outer cover plate 33. The inner cover plate 32 and the outer cover plate 33 are included in the cover plate device 3 as a pair of cover plates. The skirt plate 31, the inner cover plate 32, and the outer cover plate 33 are respectively arranged along the length direction of the truss 101.

[0032] The skirt panel 31 is positioned near the step 104 when viewed from the railing panel 2. The skirt panel 31 is opposite the side of the step 104 in the width direction of the truss 101. The skirt panel 31 is mounted to the truss 101 via mounting accessories not shown.

[0033] An inner cover plate 32 is disposed between the upper end of the skirt panel 31 and the railing panel 2. The inner cover plate 32 covers the space between the lower part of the railing panel 2 and the skirt panel 31. Thus, at the lower part of the railing panel 2, the edge of the inner cover plate 32 faces the side of one of the pair of sides of the railing panel 2 facing the step 104.

[0034] The outer cover plate 33 is positioned on the side opposite to the steps 104 when viewed from the railing panel 2. The outer cover plate 33 is mounted to the truss 101 by a mounting fitting (not shown) fixed to the truss 101. The outer cover plate 33 covers the space existing around the lower part of the railing panel 2, on the side opposite to the steps 104 when viewed from the railing panel 2. Thus, at the lower part of the railing panel 2, the edge of the outer cover plate 33 faces one of a pair of sides of the railing panel 2 opposite to the side opposite to the steps 104.

[0035] The inner lighting device 4 is disposed between the side of the railing panel 2 and the edge of the inner cover plate 32. In this embodiment, a plurality of inner lighting devices 4 are arranged along the edge of the inner cover plate 32. Furthermore, in this embodiment, the plurality of inner lighting devices 4 are arranged along the entire length of the inner cover plate 32. The outer lighting device 5 is disposed between the side of the railing panel 2 and the edge of the outer cover plate 33. In this embodiment, a plurality of outer lighting devices 5 are arranged along the edge of the outer cover plate 33. Furthermore, in this embodiment, the plurality of outer lighting devices 5 are arranged along the entire length of the outer cover plate 33.

[0036] The inner lighting device 4 and the outer lighting device 5 each have a buffer component 6 and a first light-emitting device 7. The structure of the buffer component 6 in the outer lighting device 5 is the same as that in the inner lighting device 4. The structure of the first light-emitting device 7 in the outer lighting device 5 is the same as that in the inner lighting device 4.

[0037] The buffer member 6 is an elastic member capable of elastic deformation. In this embodiment, resin is used as the material constituting the buffer member 6. The first light-emitting device 7 is disposed on the buffer member 6.

[0038] In the inner lighting device 4, a buffer member 6 is installed on the edge of the inner cover plate 32. In the inner lighting device 4, the buffer member 6 is arranged along the edge of the inner cover plate 32. That is, in the inner lighting device 4, the length direction of the buffer member 6 is along the edge of the inner cover plate 32. In the inner lighting device 4, the buffer member 6 serves as a pad to block the gap between the side of the railing panel 2 and the edge of the inner cover plate 32.

[0039] In the outer lighting device 5, a buffer member 6 is installed on the edge of the outer cover plate 33. In the outer lighting device 5, the buffer member 6 is positioned along the edge of the outer cover plate 33. That is, in the outer lighting device 5, the longitudinal direction of the buffer member 6 is along the edge of the outer cover plate 33. In the outer lighting device 5, the buffer member 6 serves as a pad to block the gap between the side of the railing panel 2 and the edge of the outer cover plate 33.

[0040] Figure 3 It means Figure 2 An enlarged cross-sectional view of the inner lighting device 4. In both the inner lighting device 4 and the outer lighting device 5, the buffer member 6 has a buffer body 61, a first buffer part 62, and a second buffer part 63.

[0041] The buffer body 61, the first buffer portion 62, and the second buffer portion 63 are arranged along the length direction of the buffer member 6. In a cross-section of the buffer member 6 on a plane perpendicular to the length direction of the buffer member 6, the first buffer portion 62 and the second buffer portion 63 protrude from the buffer body 61, respectively. On the buffer member 6, a cover plate insertion groove 64 along the length direction of the buffer member 6 is formed by the buffer body 61, the first buffer portion 62, and the second buffer portion 63.

[0042] In the inner lighting device 4, such as Figure 2 and Figure 3 As shown, the edge of the inner cover plate 32 is inserted into the cover plate insertion groove 64 formed in the buffer member 6. Thus, in the inner lighting device 4, the buffer member 6 holds the edge of the inner cover plate 32 between the first buffer portion 62 and the second buffer portion 63.

[0043] In the inner lighting device 4, the buffer body 61 is located between the side of the railing panel 2 and the edge of the inner cover plate 32. In the inner lighting device 4, the first buffer part 62 overlaps with the edge of the inner cover plate 32 on the upper side, and the second buffer part 63 overlaps with the edge of the inner cover plate 32 on the lower side.

[0044] In the outer lighting device 5, the edge of the outer cover plate 33 is inserted into the cover plate insertion groove 64 formed in the buffer member 6. Thus, in the outer lighting device 5, the buffer member 6 holds the edge of the outer cover plate 33 between the first buffer portion 62 and the second buffer portion 63.

[0045] In the outer lighting device 5, the buffer body 61 is located between the side of the railing panel 2 and the edge of the outer cover plate 33. In the outer lighting device 5, the first buffer part 62 overlaps with the edge of the outer cover plate 33 on the upper side, and the second buffer part 63 overlaps with the edge of the outer cover plate 33 on the lower side.

[0046] In both the inner lighting device 4 and the outer lighting device 5, a first light-emitting device 7 is disposed within the first buffer portion 62 of the buffer member 6. In this embodiment, the first light-emitting device 7 is disposed inside the first buffer portion 62. The first buffer portion 62 is integrally formed with the first light-emitting device 7. In this embodiment, the entire buffer member 6 is made of the same material. The material constituting the first buffer portion 62 is a light-transmitting material.

[0047] The first light-emitting device 7 is disposed on the first buffer portion 62 along the length of the buffer member 6. In this embodiment, the first light-emitting device 7 is disposed along the entire length of the buffer member 6. The first light-emitting device 7 generates light. The light generated by the first light-emitting device 7 passes through the first buffer portion 62 and illuminates the outside of the buffer member 6.

[0048] In the railing assembly 1, light is generated by the first light-emitting device 7 in the inner lighting device 4, thereby illuminating the area above the inner cover plate 32. In this embodiment, the illumination above the inner cover plate 32 is provided by multiple inner lighting devices 4 along the entire length of the inner cover plate 32. Additionally, in the railing assembly 1, light is generated by the first light-emitting device 7 in the outer lighting device 5, thereby illuminating the area above the outer cover plate 33. In this embodiment, the illumination above the outer cover plate 33 is provided by multiple outer lighting devices 5 along the entire length of the outer cover plate 33. Therefore, the railing assembly 1 becomes a railing assembly with an illumination function that illuminates the area around the railing panel 2.

[0049] like Figure 3 As shown, the first light-emitting device 7 includes a light-emitting element 71 and an element substrate 72. In this embodiment, an LED (Light Emitting Diode) is used as the light-emitting element 71. The light-emitting element 71 is mounted on the element substrate 72. A power supply line (not shown) connected to a power source is connected to the element substrate 72. The power supply line connected to the element substrate 72 extends outward from the end face of the buffer member 6 or the lower surface of the second buffer portion 63 along the length direction of the buffer member 6.

[0050] The component substrate 72 has the mounting surface of the light-emitting element 71 facing the side opposite to the cover plate insertion slot 64. Thus, the first light-emitting device 7 has the light-emitting element 71 facing the side opposite to the cover plate insertion slot 64. The light-emitting element 71 generates light by receiving power from a power source via a power supply line and the component substrate 72.

[0051] Next, we will describe, for example, the case of converting a railing device without lighting function in an escalator into a railing device 1 with lighting function. In the railing device without lighting function, resin pads are respectively arranged between the edges of the inner cover plate 32 and the outer cover plate 33 and the side of the railing panel 2. By replacing each pad with an inner lighting device 4 and an outer lighting device 5 and wiring the power supply, the railing device without lighting function is converted into a railing device 1 with lighting function.

[0052] In such an inner lighting device 4 and outer lighting device 5, the gap between the edges of the inner cover plate 32 and the outer cover plate 33 and the side of the railing panel 2 is blocked by a buffer member 6 that can elastically deform. The buffer member 6 has a first buffer portion 62 provided with a first light-emitting device 7. The first light-emitting device 7 generates light. Therefore, the inner lighting device 4 can be easily installed between the edge of the inner cover plate 32 and the side of the railing panel 2 while the buffer member 6 in the inner lighting device 4 can be elastically deformed. In addition, the outer lighting device 5 can be easily installed between the edge of the outer cover plate 33 and the side of the railing panel 2 while the buffer member 6 in the outer lighting device 5 can be elastically deformed. Thus, the inner lighting device 4 and the outer lighting device 5 can be easily installed on the escalator. Therefore, the lighting around the railing panel 2 can be easily achieved, and the design of the railing device 1 can be easily improved. Furthermore, for example, when converting a railing device without lighting function into a railing device 1 with lighting function, the pads of the railing device without lighting function can be easily replaced with inner lighting device 4 and outer lighting device 5. Therefore, it is not necessary to replace the inner cover plate 32 and outer cover plate 33 with covers for installing lighting devices in order to install inner lighting device 4 and outer lighting device 5, and the railing device without lighting function can be easily converted into a railing device 1 with lighting function.

[0053] Furthermore, the material constituting the first buffer portion 62 is a light-transmitting material. The first light-emitting device 7 is disposed inside the first buffer portion 62. Therefore, the first light-emitting device 7 can be protected by the first buffer portion 62. As a result, for example, dustproof and waterproof functions can be obtained for the first light-emitting device 7, and impacts on the first light-emitting device 7 can also be mitigated. Therefore, the occurrence of failure of the first light-emitting device 7 can be suppressed, and the lifespan of the first light-emitting device 7 can be extended.

[0054] Furthermore, the first buffer portion 62 is integrally formed with the first light-emitting device 7. This further strengthens the protection provided by the first buffer portion 62 to the first light-emitting device 7. Therefore, it more reliably suppresses the occurrence of malfunctions in the first light-emitting device 7. Additionally, the first light-emitting device 7 and the first buffer portion 62 can be integrated simultaneously during the molding of the first buffer portion 62. This facilitates the manufacturing of both the inner lighting device 4 and the outer lighting device 5.

[0055] Furthermore, the first buffer portion 62 in the inner lighting device 4 overlaps with the inner cover plate 32 on its upper side. Similarly, the first buffer portion 62 in the outer lighting device 5 overlaps with the outer cover plate 33 on its upper side. Therefore, the light from the first light-emitting device 7 of both the inner and outer lighting devices 4 and 5 can effectively reach passengers riding on the steps 104. This further enhances the design of the handrail device 1. In particular, in the inner lighting device 4, passengers riding on the steps 104 can directly see the first light-emitting device 7, improving the lighting performance of the inner lighting device 4.

[0056] Furthermore, multiple inner lighting devices 4 are arranged along the entire length of the inner cover plate 32. Multiple outer lighting devices 5 are arranged along the entire length of the outer cover plate 33. Therefore, illumination can be provided along the entire length of each inner lighting device 4 and each outer lighting device 5, as well as the inner cover plate 32 and the outer cover plate 33. This further enhances the design of the railing device 1.

[0057] Furthermore, in the railing device 1, in both the inner lighting device 4 and the outer lighting device 5, the first light-emitting device 7 is provided in the first buffer portion 62 of the buffer member 6. Therefore, the inner lighting device 4 and the outer lighting device 5 can be easily installed on the escalator. Therefore, it is not necessary to replace the inner cover plate 32 and the outer cover plate 33 with covers for installing the lighting devices in order to install the inner lighting device 4 and the outer lighting device 5, and the railing device without lighting function can be easily transformed into a railing device 1 with lighting function.

[0058] Implementation method 2.

[0059] Figure 4 This is a cross-sectional view showing the inner lighting device of the lighting device of the escalator as described in Embodiment 2. Furthermore, Figure 4 It is the same as in implementation method 1 Figure 3The corresponding diagram is shown. In this embodiment, the structure of the buffer member 6 in the outer lighting device 5 is the same as the structure of the buffer member 6 in the inner lighting device 4. Furthermore, in this embodiment, the structure of the first light-emitting device 7 in the outer lighting device 5 is the same as the structure of the first light-emitting device 7 in the inner lighting device 4.

[0060] In both the inner lighting device 4 and the outer lighting device 5, a space serving as a storage chamber 65 is formed inside the first buffer portion 62. The storage chamber 65 extends through the first buffer portion 62 along the entire length of the buffer member 6.

[0061] The first light-emitting device 7 is disposed in the storage chamber 65. A pair of storage grooves 66 are formed on the inner surface of the storage chamber 65 along the length of the buffer member 6. The pair of storage grooves 66 are opposite to each other in the storage chamber 65. The two edges of the element substrate 72 of the first light-emitting device 7 are respectively inserted into the pair of storage grooves 66. The first light-emitting device 7 is held in the storage chamber 65 with the two edges of the element substrate 72 inserted into the pair of storage grooves 66. The first light-emitting device 7 is inserted into the storage chamber 65 from the end of the first buffer portion 62 in the length direction of the buffer member 6 while the two edges of the element substrate 72 are guided by the pair of storage grooves 66. Other structures are the same as in Embodiment 1.

[0062] In both the inner lighting device 4 and the outer lighting device 5, a storage chamber 65 is formed inside the first buffer section 62. The first light-emitting device 7 is disposed within the storage chamber 65. Therefore, the position of the first light-emitting device 7 can be adjusted within the storage chamber 65. Consequently, after the first light-emitting device 7 is placed in the first buffer section 62, its position relative to the first buffer section 62 can be adjusted, for example, along the length of the buffer member 6. Therefore, the degree of freedom in adjusting the position of the first light-emitting device 7 relative to the buffer member 6 can be increased.

[0063] Furthermore, a pair of storage slots 66 are formed on the inner surface of the storage chamber 65 for inserting the two edges of the element substrate 72 of the first light-emitting device 7 into the storage slots 66. Therefore, by inserting the two edges of the element substrate 72 into the pair of storage slots 66, the first light-emitting device 7 can be held in the storage chamber 65. As a result, movement or tilting of the first light-emitting device 7 inside the first buffer portion 62 can be suppressed.

[0064] Implementation method 3.

[0065] Figure 5 This is a cross-sectional view showing the inner lighting device of the lighting device of the escalator as described in Embodiment 3. Furthermore, Figure 5 It is the same as in implementation method 1 Figure 3The corresponding figure. In this embodiment, the structures of the buffer member 6 and the first light-emitting device 7 in the outer lighting device 5 are the same as those in the inner lighting device 4. In both the inner lighting device 4 and the outer lighting device 5, the first buffer portion 62 has a receiving portion 621 and a cover portion 622.

[0066] The cover portion 622 is connected to a portion of the receiving portion 621. In this embodiment, the cover portion 622 is connected to the root portion of the receiving portion 621 relative to the buffer body portion 61. The receiving portion 621 and the cover portion 622 are arranged along the length direction of the buffer member 6 over the entire length of the first buffer portion 62. The cover portion 622 overlaps with the receiving portion 621.

[0067] The storage chamber 65 is formed between the receiving portion 621 and the cover portion 622 with the cover portion 622 overlapping. Thus, a portion of the inner surface of the storage chamber 65 is formed by the cover portion 622, and the remaining portion is formed by the receiving portion 621.

[0068] The receiving portion 621 and the cover portion 622 are each capable of elastic deformation in the direction of creating a gap between the receiving portion 621 and the cover portion 622 when the cover portion 622 is connected to the receiving portion 621. In the first buffer portion 62, when the cover portion 622 is connected to the receiving portion 621, at least one of the receiving portion 621 and the cover portion 622 elastically deforms, thereby creating an open path 623 between the receiving portion 621 and the cover portion 622. The open path 623 is a gap from the storage chamber 65 to the outside of the first buffer portion 62.

[0069] A fastening structure 67 is provided between the receiving portion 621 and the cover portion 622. The fastening structure 67 fastens the cover portion 622 to the receiving portion 621, thereby maintaining the overlap between the cover portion 622 and the receiving portion 621. In this embodiment, the fastening structure 67 is provided along the length direction of the buffer member 6 along the entire length of the first buffer portion 62. The fastening structure 67 has a protrusion 671 and a recess 672. In this embodiment, the protrusion 671 is provided on the cover portion 622, and the recess 672 is provided on the receiving portion 621.

[0070] The protrusion 671 protrudes from the cover portion 622 toward the receiving portion 621. The protrusion 671 overlaps with the cover portion 622 and the receiving portion 621 to embed into the recess 672. The cover portion 622 is fastened to the receiving portion 621 by the protrusion 671 embedding into the recess 672.

[0071] The protrusion 671 is elastically deformable. The protrusion 671 has an anti-detachment portion 671a and a connecting portion 671b. The anti-detachment portion 671a is fixed to the cover portion 622 via the connecting portion 671b. When the protrusion 671 is viewed along the length of the buffer member 6, the width of the anti-detachment portion 671a is larger than the width of the connecting portion 671b.

[0072] The recess 672 has a first space 672a and a second space 672b. The first space 672a is formed inside the receiving portion 621. The second space 672b extends from the first space 672a to the outer surface of the receiving portion 621. Thus, the first space 672a is open to the outside of the receiving portion 621 via the second space 672b.

[0073] When the recessed portion 672 is viewed along the length of the buffer member 6, the width of the first space portion 672a is greater than the width of the second space portion 672b. The width of the first space portion 672a is greater than or equal to the width of the anti-slip portion 671a. The width of the second space portion 672b is greater than or equal to the width of the connecting portion 671b and less than the width of the anti-slip portion 671a.

[0074] When the protrusion 671 is pressed against the recess 672, the anti-detachment portion 671a elastically deforms and passes through the second space portion 672b to insert into the first space portion 672a. Upon reaching the first space portion 672a, the anti-detachment portion 671a elastically returns to its original position. Thus, the protrusion 671 is embedded in the recess 672. With the protrusion 671 embedded in the recess 672, the anti-detachment portion 671a is locked against the inner surface of the first space portion 672a, thereby preventing the protrusion 671 from dislodging from the recess 672. When the protrusion 671 is pulled in a direction that would cause it to dislodge from the recess 672, the anti-detachment portion 671a elastically deforms and passes through the second space portion 672b, thereby dislodging the protrusion 671 from the recess 672.

[0075] In the first buffer portion 62, the protrusion 671 separates from the recess 672, creating an open path 623 between the receiving portion 621 and the cover portion 622, thereby allowing the first light-emitting device 7 to enter and exit the storage chamber 65 through the open path 623. Other structures are the same as in embodiment 2.

[0076] In both the inner lighting device 4 and the outer lighting device 5, a portion of the cover 622 is connected to a part of the receiving portion 621. A storage chamber 65 is formed between the receiving portion 621 and the cover 622, with the cover 622 overlapping. When the cover 622 and the receiving portion 621 are connected, at least one of the receiving portion 621 and the cover 622 elastically deforms, thereby creating an open path 623 between the receiving portion 621 and the cover 622. Therefore, the first light-emitting device 7 can easily enter and exit the storage chamber 65 through the open path 623 created between the receiving portion 621 and the cover 622. Thus, for example, it is possible to easily perform operations such as replacing the first light-emitting device 7 and maintaining or repairing it.

[0077] Furthermore, a fastening structure 67 is provided between the receiving portion 621 and the cover portion 622. The fastening structure 67 has a protrusion 671 provided on the cover portion 622 and a recess 672 into which the protrusion 671 is inserted. Therefore, the cover portion 622 can be fastened to the receiving portion 621, and the unintentional creation of an open path 623 between the cover portion 622 and the receiving portion 621 can be prevented. As a result, foreign objects such as dust, dirt, and moisture can hardly enter the storage chamber 65 from the outside of the first buffer portion 62, and the first light-emitting device 7 is less likely to malfunction.

[0078] In addition, in the above-described embodiment 3, in the fastening structure 67, the protrusion 671 is provided on the cover 622 and the recess 672 is provided on the receiving part 621. However, in the fastening structure 67, the protrusion 671 may be provided on the receiving part 621 and the recess 672 may be provided on the cover 622.

[0079] Furthermore, in the above-described embodiment 3, the protrusion 671 has an anti-detachment portion 671a and a connecting portion 671b, and the width of the anti-detachment portion 671a is larger than the width of the connecting portion 671b. However, as long as the cover portion 622 is secured to the receiving portion 621 by inserting the protrusion 671 into the recessed portion 672, the width of the protrusion 671 can also be less than or equal to the width of the connecting portion 671b.

[0080] Furthermore, in the above-described embodiment 3, the fastening structure 67 is provided along the entire length of the first buffer portion 62. However, the fastening structure 67 may also be provided only for a portion of the range of the first buffer portion 62 in the length direction of the buffer member 6. Even so, the cover portion 622 can be fastened to the receiving portion 621.

[0081] Furthermore, in the above-described embodiment 3, a fastening structure 67 is provided between the receiving portion 621 and the cover portion 622. However, the fastening structure 67 may not be present. Even without the fastening structure 67, a storage chamber 65 can be formed inside the first buffer portion 62 by overlapping the cover portion 622 and the receiving portion 621, and the first light-emitting device 7 can be disposed in the storage chamber 65.

[0082] Furthermore, in embodiments 2 and 3 described above, a pair of storage slots 66 are formed on the inner surface of the storage chamber 65 for inserting the two edges of the component substrate 72. However, the pair of storage slots 66 may not be present. In this way, the first light-emitting device 7 can also be arranged in the storage chamber 65.

[0083] Implementation method 4.

[0084] Figure 6 This is a cross-sectional view showing the inner lighting device of the lighting device of the escalator as described in Embodiment 4. Furthermore, Figure 6 It is the same as in implementation method 1 Figure 3 The corresponding figure. In this embodiment, the structures of the buffer component 6 and the first light-emitting device 7 in the outer lighting device 5 are the same as those in the inner lighting device 4. The inner lighting device 4 and the outer lighting device 5 not only have the buffer component 6 and the first light-emitting device 7, but also have a second light-emitting device 8.

[0085] In both the inner lighting device 4 and the outer lighting device 5, a second light-emitting device 8 is disposed in the second buffer portion 63 of the buffer member 6. In this embodiment, the second light-emitting device 8 is disposed inside the second buffer portion 63. The second buffer portion 63 is integrally formed with the second light-emitting device 8. The material constituting the second buffer portion 63 is a light-transmitting material.

[0086] The second light-emitting device 8 is disposed on the second buffer portion 63 along the length of the buffer member 6. In this embodiment, the second light-emitting device 8 is disposed along the entire length of the buffer member 6. The second light-emitting device 8 generates light. The light generated by the second light-emitting device 8 passes through the second buffer portion 63 and illuminates the outside of the buffer member 6.

[0087] In the inner lighting device 4, the second buffer portion 63 overlaps with the edge of the inner cover plate 32 on the lower side. In the outer lighting device 5, the second buffer portion 63 overlaps with the edge of the outer cover plate 33 on the lower side.

[0088] In the railing assembly 1, light is generated by the second light-emitting device 8 in the inner lighting device 4, thereby illuminating the area below the inner cover plate 32. In this embodiment, the illumination below the inner cover plate 32 is performed along the entire length of the inner lighting device 4. Additionally, in the railing assembly 1, light is generated by the second light-emitting device 8 in the outer lighting device 5, thereby illuminating the area below the outer cover plate 33. In this embodiment, the illumination below the outer cover plate 33 is performed along the entire length of the outer lighting device 5. By illuminating the areas below both the inner cover plate 32 and the outer cover plate 33, the inner side of the truss 101 is illuminated.

[0089] The second light-emitting device 8 has a light-emitting element 81 and an element substrate 82. In this embodiment, an LED is used as the light-emitting element 81. The light-emitting element 81 is mounted on the element substrate 82. A power supply line (not shown) connected to a power source is connected to the element substrate 82. The power supply line connected to the element substrate 82 extends outward from the end face of the buffer member 6 or the lower surface of the second buffer portion 63 in the longitudinal direction of the buffer member 6.

[0090] The component substrate 82 has its mounting surface, on which the light-emitting element 81 is mounted, facing the side opposite to the cover plate insertion slot 64. Thus, the second light-emitting device 8 has its light-emitting element 81 facing the side opposite to the cover plate insertion slot 64. The light-emitting element 81 generates light by receiving power from a power source via a power supply line and the component substrate 82. Other structures are the same as in Embodiment 1.

[0091] In both the inner lighting device 4 and the outer lighting device 5, a second light-emitting device 8 is provided on the second buffer portion 63 of the buffer member 6. In the inner lighting device 4, the second buffer portion 63 overlaps with the edge of the inner cover plate 32 on its lower side. In the outer lighting device 5, the second buffer portion 63 overlaps with the edge of the outer cover plate 33 on its lower side. Therefore, the inner side of the truss 101, which is located below the inner cover plate 32 and the outer cover plate 33, can be illuminated by the inner lighting device 4 and the outer lighting device 5. Thus, for example, when performing maintenance and repair work on the inner side of the escalator, the inner lighting device 4 and the outer lighting device 5 can be utilized.

[0092] Furthermore, in the above-described embodiment 4, the second light-emitting device 8 is arranged along the entire length of the buffer member 6. However, the second light-emitting device 8 may also be arranged only along a portion of the entire length of the buffer member 6.

[0093] Furthermore, in the above embodiment 4, the second light-emitting device 8 is disposed inside the second buffer portion 63. However, the second light-emitting device 8 may also be disposed on the outer surface of the second buffer portion 63.

[0094] Furthermore, in Embodiment 4 described above, the second buffer portion 63 is integrally formed with the second light-emitting device 8. However, similar to the first buffer portion 62 in Embodiment 2, a space serving as a storage chamber may be formed inside the second buffer portion 63, and the second light-emitting device 8 may be disposed within the storage chamber of the second buffer portion 63.

[0095] Furthermore, in Embodiment 4 described above, similar to the first buffer portion 62 in Embodiment 3, the second buffer portion 63 may also have a receiving portion and a cover portion connected to the receiving portion. In this case, a storage chamber is formed between the receiving portion and the cover portion in the second buffer portion 63 when the cover portion overlaps with the receiving portion. Additionally, in this case, a second light-emitting device 8 is disposed in the storage chamber formed in the second buffer portion 63. Thus, in this case, in the second buffer portion 63, when the cover portion is connected to the receiving portion, at least one of the receiving portion and the cover portion elastically deforms, thereby creating a gap between the receiving portion and the cover portion that allows access from the storage chamber to the outside of the second buffer portion 63 as an open path.

[0096] Furthermore, in each of the above embodiments, the inner lighting device 4 and the outer lighting device 5 are included in the railing device 1. However, instead of the outer lighting device 5, a buffer member 6 without a light-emitting device may be provided between the side of the railing panel 2 and the edge of the outer cover plate 33. Alternatively, instead of the inner lighting device 4, a buffer member 6 without a light-emitting device may be provided between the side of the railing panel 2 and the edge of the inner cover plate 32. Even so, either the inner lighting device 4 or the outer lighting device 5 can be easily provided, and the area around the railing panel 2 can be illuminated by either the inner lighting device 4 or the outer lighting device 5.

[0097] Furthermore, in each of the above embodiments, the first light-emitting device 7 is arranged along the entire length of the buffer member 6. However, the first light-emitting device 7 may also be arranged only along a portion of the entire length of the buffer member 6.

[0098] Furthermore, in each of the above embodiments, the first light-emitting device 7 is disposed inside the first buffer portion 62. However, the first light-emitting device 7 may also be disposed on the outer surface of the first buffer portion 62.

[0099] Furthermore, in each of the above embodiments, at least one of the color and brightness of the light emitted by the first light-emitting device 7 of the inner lighting device 4 can be different depending on the location along the length of the inner cover plate 32. This allows for the indication of specific locations within the escalator to passengers through variations in the color and brightness of the light emitted by the first light-emitting device 7 of the inner lighting device 4. For example, the brightness of the light emitted by the first light-emitting device 7 of the inner lighting device 4 on both the upper and lower floors can be made brighter than the brightness of the light emitted by the first light-emitting device 7 of the inner lighting device 4 in the intermediate section between the upper and lower floors. This brightly illuminates the area around the boarding / alighting points, indicating the boarding / alighting points of the upper and lower floors to passengers.

[0100] Furthermore, in each of the above embodiments, at least one of the color and brightness of the light emitted by the first light-emitting device 7 of the outer lighting device 5 can be different depending on the location along the length of the outer cover plate 33. Even so, it is possible to indicate a specific location in the escalator to passengers by changing at least one of the color and brightness of the light emitted by the first light-emitting device 7 of the outer lighting device 5.

[0101] Furthermore, in each of the above embodiments, the light emitted by the first light-emitting device 7 of at least one of the inner lighting device 4 and the outer lighting device 5 can be directed toward the side of the railing panel 2, and the light emitted by the first light-emitting device 7 can be scattered by the side of the railing panel 2. In this way, indirect lighting can be achieved through at least one of the inner lighting device 4 and the outer lighting device 5.

[0102] Furthermore, in each of the above embodiments, the illuminated handrail device 1, which includes an inner lighting device 4 and an outer lighting device 5, is applied to an escalator. However, the illuminated handrail device 1, which includes an inner lighting device 4 and an outer lighting device 5, can also be applied to a moving walkway that serves as a passenger conveyor.

[0103] The above-described embodiments represent one example of the content of this disclosure. These embodiments can be combined with other known technologies. Parts of the structure of the embodiments can be omitted or modified without departing from the spirit of this disclosure.
