Description

[Technical Field]

[0001] The present disclosure relates to a lighting device for a passenger conveyor and a balustrade device for a passenger conveyor. [Background technology]

[0002] Patent document 1 discloses a lighting device for a passenger conveyor in which a light source is provided on a base that supports a balustrade panel, and a convex mirror-shaped reflector is provided on the top of the balustrade panel, so that light from the light source is reflected by the reflector. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-56392 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional passenger conveyor lighting device disclosed in Patent Document 1, the structure of the base supporting the balustrade panel must be specially designed to ensure space for installing the light source. Therefore, for example, when changing the specifications of the standard balustrade of an existing or under-manufacturing passenger conveyor to a balustrade specification for installing a lighting device, the entire structure of the base supporting the balustrade panel must be changed, which increases the number of parts that need to be replaced. As a result, the conventional lighting device disclosed in Patent Document 1 increases the workload of installing the lighting device on the passenger conveyor.

[0005] The present disclosure is intended to solve the above-mentioned problems, and aims to provide a passenger conveyor lighting device and a passenger conveyor handrail device that can be easily installed on a passenger conveyor. [Means for solving the problem]

[0006] The passenger conveyor lighting device of the present disclosure comprises an elastically deformable buffer member that fills the gap between the edge of the deck facing the side of the balustrade panel at the bottom of the balustrade panel and the side of the balustrade panel, and a first light-emitting device that emits light, and the buffer member has a first buffer portion in which the first light-emitting device is provided. [Effects of the Invention]

[0007] The passenger conveyor lighting device and passenger conveyor handrail device according to the present disclosure can be easily installed on the passenger conveyor. [Brief explanation of the drawings]

[0009] The following describes embodiments of the subject matter of the present disclosure with reference to the accompanying drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. Note that the subject matter of the present disclosure is not limited to the following embodiments, and any component of the embodiments may be modified or omitted within the scope of the gist of the present disclosure.

[0010] Embodiment 1 FIG. 1 is a side view showing an escalator as a passenger conveyor according to the first embodiment. In the figure, a truss 101 is installed between an upper floor and a lower floor. One longitudinal end of the truss 101 is hung on a structure on the upper floor as the upper end of the truss 101. The other longitudinal end of the truss 101 is hung on a structure on the lower floor as the lower end of the truss 101. The width direction of the truss 101 coincides with the horizontal direction perpendicular to the longitudinal direction of the truss 101.

[0011] An upper machine room is provided inside the upper end of the truss 101. A lower machine room is provided inside the lower end of the truss 101. The upper machine room is provided with an upper sprocket 102, a driving machine (not shown), and a conveyor control device (described later). The lower machine room is provided with a lower sprocket 103.

[0012] A plurality of steps 104 on which passengers can board are supported on the truss 101. The plurality of steps 104 are endlessly connected by a step chain 105. The step chain 105 is wound around an upper sprocket 102 and a lower sprocket 103.

[0013] The drive machine generates a driving force that causes each step 104 to move cyclically. The conveyor control device controls the operation of the escalator. The drive machine is controlled by the conveyor control device. The upper sprocket 102 rotates by receiving the driving force from the drive machine. As the upper sprocket 102 rotates, each step 104 moves cyclically between the upper machine room and the lower machine room.

[0014] A pair of balustrade devices 1 are provided on the truss 101, facing each other in the width direction of the truss 101. An endless moving handrail 106 is individually provided on the periphery of each balustrade device 1. Each moving handrail 106 moves along the periphery of each balustrade device 1 in synchronization with each step 104 by the driving force of a driving machine.

[0015] Figure 2 is a cross-sectional view taken along line II-II in Figure 1. Each balustrade device 1 has a balustrade panel 2, a deck device 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 in each balustrade device 1 as a pair of lighting devices.

[0016] The balustrade panel 2 is a transparent glass panel that is erected on the truss 101. The balustrade panel 2 is arranged along the longitudinal direction of the truss 101. The lower part of the balustrade panel 2 is held by a panel holding part (not shown) that is fixed to the truss 101.

[0017] The deck device 3 is disposed below the parapet panel 2. The deck device 3 covers the space that exists around the lower part of the parapet panel 2. The panel holding portion that holds the lower part of the parapet panel 2 is covered by the deck device 3.

[0018] The deck device 3 has a skirt guard 31, an inner deck 32, and an outer deck 33. The inner deck 32 and the outer deck 33 are included as a pair of decks in the deck device 3. The skirt guard 31, the inner deck 32, and the outer deck 33 are each arranged along the longitudinal direction of the truss 101.

[0019] The skirt guard 31 is disposed in a position close to the step 104 when viewed from the balustrade panel 2. The skirt guard 31 faces the side of the step 104 in the width direction of the truss 101. The skirt guard 31 is attached to the truss 101 via mounting brackets (not shown).

[0020] The inner deck 32 is disposed between the upper end of the skirt guard 31 and the balustrade panel 2. The inner deck 32 covers the space that exists between the lower part of the balustrade panel 2 and the skirt guard 31. As a result, at the lower part of the balustrade panel 2, the edge of the inner deck 32 faces the side of the pair of side surfaces of the balustrade panel 2 that faces the step 104 side.

[0021] The outer deck 33 is disposed on the opposite side of the steps 104 from the balustrade panel 2. The outer deck 33 is attached to the truss 101 by mounting brackets (not shown) that are fixed to the truss 101. The outer deck 33 covers the space that exists around the lower part of the balustrade panel 2, on the opposite side of the steps 104 from the balustrade panel 2. As a result, at the lower part of the balustrade panel 2, the edge of the outer deck 33 faces the side of the pair of side surfaces of the balustrade panel 2 that faces away from the steps 104.

[0022] The inner lighting device 4 is arranged between the side of the balustrade panel 2 and the edge of the inner deck 32. In this embodiment, a plurality of inner lighting devices 4 are arranged in a row along the edge of the inner deck 32. Also, in this embodiment, a plurality of inner lighting devices 4 are arranged over the entire length of the inner deck 32. The outer lighting device 5 is arranged between the side of the balustrade panel 2 and the edge of the outer deck 33. In this embodiment, a plurality of outer lighting devices 5 are arranged in a row along the edge of the outer deck 33. Also, in this embodiment, a plurality of outer lighting devices 5 are arranged over the entire length of the outer deck 33.

[0023] Each of the inner lighting device 4 and the outer lighting device 5 has a buffer member 6 and a first light-emitting device 7. The configuration of the buffer member 6 in the outer lighting device 5 is similar to the configuration of the buffer member 6 in the inner lighting device 4. The configuration of the first light-emitting device 7 in the outer lighting device 5 is similar to the configuration of the first light-emitting device 7 in the inner lighting device 4.

[0024] The buffer member 6 is an elastic member that is elastically deformable. In the present embodiment, a resin is used as the material that forms the buffer member 6. The first light emitting device 7 is provided on the buffer member 6.

[0025] In the inner lighting device 4, the buffer member 6 is attached to the edge of the inner deck 32. In the inner lighting device 4, the buffer member 6 is arranged along the edge of the inner deck 32. That is, in the inner lighting device 4, the longitudinal direction of the buffer member 6 is oriented along the edge of the inner deck 32. In the inner lighting device 4, the buffer member 6 is used as a packing that seals the gap between the side surface of the balustrade panel 2 and the edge of the inner deck 32.

[0026] In the exterior lighting device 5, the buffer member 6 is attached to the edge of the exterior deck 33. In the exterior lighting device 5, the buffer member 6 is arranged along the edge of the exterior deck 33. That is, in the exterior lighting device 5, the longitudinal direction of the buffer member 6 is oriented along the edge of the exterior deck 33. In the exterior lighting device 5, the buffer member 6 is used as a packing that seals the gap between the side surface of the balustrade panel 2 and the edge of the exterior deck 33.

[0027] Fig. 3 is an enlarged cross-sectional view showing the inner lighting device 4 of Fig. 2. In each of the inner lighting device 4 and the outer lighting device 5, the buffer member 6 has a buffer main body portion 61, a first buffer portion 62, and a second buffer portion 63.

[0028] The buffer main body 61, the first buffer part 62, and the second buffer part 63 are arranged along the longitudinal direction of the buffer member 6. In a cross section of the buffer member 6 taken along a plane perpendicular to the longitudinal direction of the buffer member 6, the first buffer part 62 and the second buffer part 63 each protrude from the buffer main body 61. In the buffer member 6, a deck insertion groove 64 extending along the longitudinal direction of the buffer member 6 is formed by the buffer main body 61, the first buffer part 62, and the second buffer part 63.

[0029] 2 and 3, in the inner lighting device 4, the edge of the inner deck 32 is inserted into the deck insertion groove 64 formed in the buffer member 6. As a result, in the inner lighting device 4, the buffer member 6 sandwiches the edge of the inner deck 32 between the first buffer portion 62 and the second buffer portion 63.

[0030] In the inner lighting device 4, a buffer main body portion 61 is interposed between the side surface of the balustrade panel 2 and the edge of the inner deck 32. In the inner lighting device 4, the first buffer portion 62 overlaps the edge of the inner deck 32 on the upper side of the inner deck 32, and the second buffer portion 63 overlaps the edge of the inner deck 32 on the lower side of the inner deck 32.

[0031] In the external lighting device 5, the edge of the outer deck 33 is inserted into the deck insertion groove 64 formed in the buffer member 6. As a result, in the external lighting device 5, the buffer member 6 sandwiches the edge of the outer deck 33 between the first buffer portion 62 and the second buffer portion 63.

[0032] In the exterior lighting device 5, a buffer main body portion 61 is interposed between the side surface of the balustrade panel 2 and the edge of the exterior deck 33. In the exterior lighting device 5, the first buffer portion 62 overlaps the edge of the exterior deck 33 on the upper side of the exterior deck 33, and the second buffer portion 63 overlaps the edge of the exterior deck 33 on the lower side of the exterior deck 33.

[0033] In each of the inner illumination device 4 and the outer illumination device 5, the first light-emitting device 7 is provided in the first buffer section 62 of the buffer member 6. In this embodiment, the first light-emitting device 7 is provided inside the first buffer section 62. The first buffer section 62 is integrated with the first light-emitting device 7 by integral molding. In this embodiment, the entire buffer member 6 is made of the same material. The material that makes up the first buffer section 62 is a light-transmitting material.

[0034] The first light emitting device 7 is provided in the first buffer section 62 along the longitudinal direction of the buffer member 6. In this embodiment, the first light emitting device 7 is arranged over 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 section 62 and is irradiated to the outside of the buffer member 6.

[0035] In the balustrade device 1, the first light-emitting device 7 in the inner lighting device 4 generates light, thereby providing illumination above the inner deck 32. In this embodiment, illumination above the inner deck 32 is provided by a plurality of inner lighting devices 4 over the entire length of the inner deck 32. Also, in the balustrade device 1, the first light-emitting device 7 in the outer lighting device 5 generates light, thereby providing illumination above the outer deck 33. In this embodiment, illumination above the outer deck 33 is provided by a plurality of outer lighting devices 5 over the entire length of the outer deck 33. Therefore, the balustrade device 1 is a balustrade device with a lighting function that provides illumination around the balustrade panel 2.

[0036] As shown in FIG. 3 , the first light-emitting device 7 has 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 to the outside of the buffer member 6 from an end face of the buffer member 6 in the longitudinal direction of the buffer member 6 or from the lower surface of the second buffer section 63.

[0037] The element substrate 72 is arranged with the mounting surface on which the light emitting element 71 is mounted facing away from the deck insertion groove 64. As a result, the first light emitting device 7 is arranged with the light emitting element 71 facing away from the deck insertion groove 64. The light emitting element 71 generates light by receiving power from a power source via the power supply line and the element substrate 72.

[0038] Next, we will explain the case where, for example, a balustrade device without lighting function is modified into a balustrade device 1 with lighting function, for example, in an escalator. In a balustrade device without lighting function, only resin packings are placed between the edges of the inner deck 32 and the outer deck 33 and the side of the balustrade panel 2. The balustrade device without lighting function can be modified into a balustrade device 1 with lighting function by replacing each packing with an inner lighting device 4 and an outer lighting device 5 and wiring a power supply line.

[0039] In the inner lighting device 4 and the outer lighting device 5, the gap between the edge of each of the inner deck 32 and the outer deck 33 and the side of the balustrade panel 2 is filled with an elastically deformable buffer member 6. The buffer member 6 has a first buffer portion 62 provided with a first light-emitting device 7. The first light-emitting device 7 emits light. Therefore, the inner lighting device 4 can be easily installed between the edge of the inner deck 32 and the side of the balustrade panel 2 while elastically deforming the buffer member 6 of the inner lighting device 4. Furthermore, the outer lighting device 5 can be easily installed between the edge of the outer deck 33 and the side of the balustrade panel 2 while elastically deforming the buffer member 6 of the outer lighting device 5. This makes it easy to install the inner lighting device 4 and the outer lighting device 5 on the escalator. Therefore, lighting around the balustrade panel 2 can be easily provided, and the design of the balustrade device 1 can be easily improved. Furthermore, for example, when modifying a balustrade device without a lighting function into a balustrade device 1 with a lighting function, the packings of the balustrade device without a lighting function can be easily replaced with the inside lighting device 4 and the outside lighting device 5. This eliminates the need to replace the inside deck 32 and the outside deck 33 with decks for installing lighting devices in order to install the inside lighting device 4 and the outside lighting device 5, and the balustrade device without a lighting function can be easily modified into the balustrade device 1 with a lighting function.

[0040] Furthermore, the material forming the first buffer section 62 is a light-transmitting material. The first light-emitting device 7 is provided inside the first buffer section 62. Therefore, the first light-emitting device 7 can be protected by the first buffer section 62. This, for example, can provide dustproof and waterproof functions to the first light-emitting device 7, and can also mitigate impacts that the first light-emitting device 7 receives. Therefore, it is possible to prevent failures of the first light-emitting device 7 and extend the life of the first light-emitting device 7.

[0041] Furthermore, the first buffer portion 62 is integrated with the first light-emitting device 7 by integral molding. This further enhances the protection of the first light-emitting device 7 by the first buffer portion 62. Therefore, it is possible to more reliably prevent the occurrence of failures in the first light-emitting device 7. Furthermore, the first light-emitting device 7 and the first buffer portion 62 can be integrated at the same time as molding the first buffer portion 62. This makes it easier to manufacture each of the inner illumination device 4 and the outer illumination device 5.

[0042] Furthermore, the first buffer portion 62 of the inner lighting device 4 overlaps the inner deck 32 above the inner deck 32. The first buffer portion 62 of the outer lighting device 5 overlaps the outer deck 33 above the outer deck 33. This allows the light from the first light-emitting devices 7 of each of the inner lighting device 4 and the outer lighting device 5 to effectively reach passengers standing on the steps 104. This further improves the design of the balustrade device 1. In particular, the inner lighting device 4 allows passengers standing on the steps 104 to directly see the first light-emitting devices 7, thereby enhancing the dramatic effect of the lighting provided by the inner lighting device 4.

[0043] Furthermore, the multiple inner lighting devices 4 are arranged along the entire length of the inner deck 32. The multiple outer lighting devices 5 are arranged along the entire length of the outer deck 33. Therefore, lighting can be provided by each of the inner lighting devices 4 and each of the outer lighting devices 5 along the entire length of each of the inner deck 32 and the outer deck 33. This further improves the design of the balustrade device 1.

[0044] Furthermore, in the balustrade device 1, the first light-emitting device 7 is provided in the first buffer portion 62 of the buffer member 6 in each of the inside lighting device 4 and the outside lighting device 5. This makes it possible to easily install the inside lighting device 4 and the outside lighting device 5 on the escalator. Therefore, it is no longer necessary to replace the inside deck 32 and the outside deck 33 with decks for installing lighting devices in order to install the inside lighting device 4 and the outside lighting device 5, and a balustrade device without lighting function can be easily modified into a balustrade device 1 with lighting function.

[0045] Embodiment 2 FIG. 4 is a cross-sectional view showing an inner lighting device, which is an escalator lighting device according to embodiment 2. FIG. 4 corresponds to FIG. 3 in embodiment 1. In this embodiment, the configuration of the buffer member 6 in the outer lighting device 5 is the same as the configuration of the buffer member 6 in the inner lighting device 4. Also, in this embodiment, the configuration of the first light-emitting device 7 in the outer lighting device 5 is the same as the configuration of the first light-emitting device 7 in the inner lighting device 4.

[0046] In each of 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 section 62. The storage chamber 65 penetrates the first buffer section 62 over the entire length of the buffer member 6.

[0047] The first light emitting device 7 is disposed in the accommodation chamber 65. A pair of accommodation grooves 66 is formed on the inner surface of the accommodation chamber 65 along the longitudinal direction of the buffer member 6. The pair of accommodation grooves 66 face each other in the accommodation chamber 65. Both edge portions of an element substrate 72 of the first light emitting device 7 are individually inserted into the pair of accommodation grooves 66. The first light emitting device 7 is held in the accommodation chamber 65 with both edge portions of the element substrate 72 inserted into the pair of accommodation grooves 66. The first light emitting device 7 is inserted into the accommodation chamber 65 from the end of the first buffer member 62 in the longitudinal direction of the buffer member 6, with both edge portions of the element substrate 72 being guided by the pair of accommodation grooves 66. The other configuration is the same as in the first embodiment.

[0048] In such an inner lighting device 4 and an outer lighting device 5, a space serving as an accommodation chamber 65 is formed inside the first buffer section 62. The first light-emitting device 7 is disposed in the accommodation chamber 65. This makes it possible to adjust the position of the first light-emitting device 7 in the accommodation chamber 65. As a result, after the first light-emitting device 7 is provided in the first buffer section 62, the position of the first light-emitting device 7 relative to the first buffer section 62 can be adjusted, for example, in the longitudinal direction of the buffer member 6. This improves the degree of freedom in adjusting the position of the first light-emitting device 7 relative to the buffer member 6.

[0049] Furthermore, a pair of accommodation grooves 66 into which both edge portions of the element substrate 72 of the first light emitting device 7 are individually inserted are formed on the inner surface of the accommodation chamber 65. Therefore, by individually inserting both edge portions of the element substrate 72 into the pair of accommodation grooves 66, the first light emitting device 7 can be held in the accommodation chamber 65. This makes it possible to prevent the first light emitting device 7 from moving or tilting inside the first buffer section 62.

[0050] Embodiment 3 Fig. 5 is a cross-sectional view showing an inner lighting device, which is an escalator lighting device according to embodiment 3. Fig. 5 corresponds to Fig. 3 in embodiment 1. In this embodiment, the buffer member 6 and the first light-emitting device 7 in the outer lighting device 5 are configured similarly to the buffer member 6 and the first light-emitting device 7 in the inner lighting device 4. In each of the inner lighting device 4 and the outer lighting device 5, the first buffer portion 62 has a receiving portion 621 and a lid portion 622.

[0051] The lid portion 622 is connected to a part of the receiving portion 621. In this embodiment, the lid portion 622 is connected to the base portion of the receiving portion 621 that is attached to the buffer main body portion 61. The receiving portion 621 and the lid portion 622 are arranged along the longitudinal direction of the buffer member 6 over the entire length of the first buffer portion 62. The lid portion 622 overlaps the receiving portion 621.

[0052] The storage chamber 65 is formed between the receiving portion 621 and the lid portion 622 in a state where the lid portion 622 overlaps the receiving portion 621. As a result, a part of the inner surface of the storage chamber 65 is formed by the lid portion 622, and the remaining part is formed by the receiving portion 621.

[0053] Each of the receiving portion 621 and the lid portion 622 is elastically deformable in a direction that creates a gap between the receiving portion 621 and the lid portion 622 while the lid portion 622 remains connected to the receiving portion 621. In the first buffering portion 62, an open path 623 is created between the receiving portion 621 and the lid portion 622 by at least one of the receiving portion 621 and the lid portion 622 elastically deforming while the lid portion 622 remains connected to the receiving portion 621. The open path 623 is a gap that extends from the storage chamber 65 to the outside of the first buffering portion 62.

[0054] A retaining structure 67 is provided between the receiving portion 621 and the lid portion 622. The retaining structure 67 retains the lid portion 622 on the receiving portion 621, thereby maintaining the lid portion 622 overlapping the receiving portion 621. In this embodiment, the retaining structure 67 is provided along the longitudinal direction of the buffer member 6 over the entire length of the first buffering portion 62. The retaining structure 67 has a protrusion 671 and a recess 672. In this embodiment, the protrusion 671 is provided on the lid portion 622, and the recess 672 is provided on the receiving portion 621.

[0055] Protrusion 671 protrudes from lid portion 622 toward receiving portion 621. Protrusion 671 fits into recess 672 when lid portion 622 overlaps receiving portion 621. Lid portion 622 remains in receiving portion 621 when protrusion 671 fits into recess 672.

[0056] Protrusion 671 is elastically deformable. Protrusion 671 has a retaining portion 671a and a connecting portion 671b. Retaining portion 671a is fixed to lid portion 622 via connecting portion 671b. When protrusion 671 is viewed along the longitudinal direction of buffer member 6, the width of retaining portion 671a is greater than the width of connecting portion 671b.

[0057] 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. As a result, the first space 672a is open to the outside of the receiving portion 621 via the second space 672b.

[0058] When the recess 672 is viewed along the longitudinal direction of the buffer member 6, the width of the first space 672a is larger than the width of the second space 672b. The width of the first space 672a is equal to or larger than the width of the retaining portion 671a. The width of the second space 672b is equal to or larger than the width of the connecting portion 671b, but smaller than the width of the retaining portion 671a.

[0059] When the protrusion 671 is pressed against the recess 672, the retaining portion 671a is inserted into the first space 672a through the second space 672b while elastically deforming. The retaining portion 671a, which has reached the first space 672a, elastically restores its original shape in the first space 672a. This causes the protrusion 671 to fit into the recess 672. When the protrusion 671 is fitted into the recess 672, the retaining portion 671a engages with the inner surface of the first space 672a, thereby preventing the protrusion 671 from coming out of the recess 672. When the protrusion 671 is pulled in a direction to be removed from the recess 672, the retaining portion 671a passes through the second space 672b while elastically deforming, causing the protrusion 671 to come out of the recess 672.

[0060] In the first buffering section 62, the protrusion 671 is disengaged from the recess 672 to form an open path 623 between the receiving section 621 and the lid section 622, thereby enabling the first light-emitting device 7 to be taken in and out of the accommodation chamber 65 through the open path 623. The other configurations are the same as those in the second embodiment.

[0061] In such an inner illumination device 4 and an outer illumination device 5, the lid portion 622 is connected to a part of the receiving portion 621. The storage chamber 65 is formed between the receiving portion 621 and the lid portion 622 in a state in which the lid portion 622 overlaps the receiving portion 621. When at least one of the receiving portion 621 and the lid portion 622 elastically deforms while the lid portion 622 remains connected to the receiving portion 621, an open path 623 is formed between the receiving portion 621 and the lid portion 622. This makes it easier to insert and remove the first light-emitting device 7 into and from the storage chamber 65 through the open path 623 formed between the receiving portion 621 and the lid portion 622. This makes it easier to perform tasks such as replacing the first light-emitting device 7 and performing maintenance and inspection of the first light-emitting device 7, for example.

[0062] Furthermore, a retaining structure 67 is provided between the receiving portion 621 and the lid portion 622. The retaining structure 67 has a protrusion 671 provided on the lid portion 622 and a recess 672 into which the protrusion 671 fits. This allows the lid portion 622 to be secured to the receiving portion 621, and prevents an unintentional creation of an open path 623 between the lid portion 622 and the receiving portion 621. This makes it difficult for foreign matter such as dust, dirt, and moisture to enter the accommodation chamber 65 from outside the first buffer portion 62, and makes the first light-emitting device 7 less susceptible to breakdowns.

[0063] In the third embodiment, in fastening structure 67, protrusion 671 is provided on lid portion 622, and recess 672 is provided on receiving portion 621. However, in fastening structure 67, protrusion 671 may be provided on receiving portion 621, and recess 672 may be provided on lid portion 622.

[0064] In the third embodiment, protrusion 671 has retaining portion 671a and connecting portion 671b, and the width of retaining portion 671a is greater than the width of connecting portion 671b. However, as long as protrusion 671 fits into recess 672 to allow lid portion 622 to remain in receiving portion 621, the width of protrusion 671 may be equal to or smaller than the width of connecting portion 671b.

[0065] In the third embodiment, the fastening structure 67 is provided over the entire length of the first buffer section 62. However, the fastening structure 67 may be provided only in a portion of the range of the first buffer section 62 in the longitudinal direction of the buffer member 6. In this case, the lid section 622 can be fastened to the receiving section 621.

[0066] In the third embodiment, retaining structure 67 is provided between receiving portion 621 and lid portion 622. However, retaining structure 67 does not have to be provided. Even without retaining structure 67, lid portion 622 overlaps receiving portion 621, thereby forming accommodation chamber 65 inside first buffer portion 62, and first light-emitting device 7 can be placed in accommodation chamber 65.

[0067] In the second and third embodiments, a pair of accommodation grooves 66 into which both edges of the element substrate 72 are individually inserted are formed on the inner surface of the accommodation chamber 65. However, the pair of accommodation grooves 66 may be omitted. In this case, the first light-emitting device 7 can also be disposed in the accommodation chamber 65.

[0068] Embodiment 4 Fig. 6 is a cross-sectional view showing an inner lighting device, which is an escalator lighting device according to embodiment 4. Fig. 6 corresponds to Fig. 3 in embodiment 1. In this embodiment, the buffer member 6 and the first light-emitting device 7 in the outer lighting device 5 are configured similarly to the buffer member 6 and the first light-emitting device 7 in the inner lighting device 4. Each of the inner lighting device 4 and the outer lighting device 5 has a second light-emitting device 8 in addition to the buffer member 6 and the first light-emitting device 7.

[0069] In each of the inner illumination device 4 and the outer illumination device 5, the second light emitting device 8 is provided in the second buffer portion 63 of the buffer member 6. In the present embodiment, the second light emitting device 8 is provided inside the second buffer portion 63. The second buffer portion 63 is integrated with the second light emitting device 8 by integral molding. The material forming the second buffer portion 63 is a light-transmitting material.

[0070] The second light emitting device 8 is provided in the second buffer section 63 along the longitudinal direction of the buffer member 6. In this embodiment, the second light emitting device 8 is arranged over 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 section 63 and is irradiated to the outside of the buffer member 6.

[0071] In the inner lighting device 4, the second buffer portion 63 overlaps the edge of the inner deck 32 on the underside of the inner deck 32. In the outer lighting device 5, the second buffer portion 63 overlaps the edge of the outer deck 33 on the underside of the outer deck 33.

[0072] In the balustrade device 1, the second light-emitting device 8 in the inner lighting device 4 generates light, thereby illuminating the area below the inner deck 32. In this embodiment, the illumination below the inner deck 32 is provided over the entire length of the inner lighting device 4. Also, in the balustrade device 1, the second light-emitting device 8 in the outer lighting device 5 generates light, thereby illuminating the area below the outer deck 33. In this embodiment, the illumination below the outer deck 33 is provided over the entire length of the outer lighting device 5. By illuminating the areas below the inner deck 32 and the outer deck 33, the inside of the truss 101 is illuminated.

[0073] 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 to the outside of the buffer member 6 from an end face of the buffer member 6 in the longitudinal direction of the buffer member 6 or from the lower surface of the second buffer section 63.

[0074] The element substrate 82 is arranged so that the mounting surface on which the light emitting element 81 is mounted faces the opposite side to the deck insertion groove 64. As a result, the second light emitting device 8 is arranged so that the light emitting element 81 faces the opposite side to the deck insertion groove 64. The light emitting element 81 generates light by receiving power from a power source via a power supply line and the element substrate 82. The other configurations are the same as those in the first embodiment.

[0075] In such an inner lighting device 4 and an outer lighting device 5, a second light-emitting device 8 that emits light is provided in a second buffer portion 63 of the buffer member 6. In the inner lighting device 4, the second buffer portion 63 overlaps the edge of the inner deck 32 on the underside of the inner deck 32. In the outer lighting device 5, the second buffer portion 63 overlaps the edge of the outer deck 33 on the underside of the outer deck 33. This allows the inner lighting device 4 and the outer lighting device 5 to illuminate the inside of the truss 101 that is located below each of the inner deck 32 and the outer deck 33. Therefore, for example, the inner lighting device 4 and the outer lighting device 5 can be used when performing maintenance and inspection work on an escalator inside the truss 101.

[0076] In the fourth embodiment, the second light emitting device 8 is disposed over the entire length of the buffer member 6. However, the second light emitting device 8 may be disposed over only a part of the entire length of the buffer member 6.

[0077] In the fourth embodiment, the second light emitting device 8 is provided inside the second buffer section 63. However, the second light emitting device 8 may be provided on the outer surface of the second buffer section 63.

[0078] In the fourth embodiment, the second buffer section 63 is integrally molded with the second light emitting device 8. However, similar to the first buffer section 62 in the second embodiment, a space serving as a storage chamber may be formed inside the second buffer section 63, and the second light emitting device 8 may be disposed in the storage chamber of the second buffer section 63.

[0079] Furthermore, in the above-described fourth embodiment, similarly to the first buffering section 62 in the third embodiment, the second buffering section 63 may have a receiving section and a lid section connected to the receiving section. In this case, in the second buffering section 63, a storage chamber is formed between the receiving section and the lid section with the lid section overlapping the receiving section. Also, in this case, the second light-emitting device 8 is placed in the storage chamber formed in the second buffering section 63. As a result, in this case, in the second buffering section 63, at least one of the receiving section and the lid section elastically deforms while the lid section remains connected to the receiving section, and a gap is formed between the receiving section and the lid section as an open path that extends from the storage chamber to the outside of the second buffering section 63.

[0080] In addition, in each of the above-described embodiments, the inner lighting device 4 and the outer lighting device 5 are included in the balustrade device 1. However, a buffer member 6 not provided with a light-emitting device may be arranged between the side surface of the balustrade panel 2 and the edge of the outer deck 33 instead of the outer lighting device 5. Also, a buffer member 6 not provided with a light-emitting device may be arranged between the side surface of the balustrade panel 2 and the edge of the inner deck 32 instead of the inner lighting device 4. Even in these cases, either the inner lighting device 4 or the outer lighting device 5 can be easily installed, and either the inner lighting device 4 or the outer lighting device 5 can illuminate the periphery of the balustrade panel 2.

[0081] In each of the above-described embodiments, the first light emitting device 7 is disposed over the entire length of the buffer member 6. However, the first light emitting device 7 may be disposed over only a part of the entire length of the buffer member 6.

[0082] In each of the above-described embodiments, the first light emitting device 7 is provided inside the first buffer section 62. However, the first light emitting device 7 may be provided on the outer surface of the first buffer section 62.

[0083] Furthermore, in each of the above-described 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 may be varied depending on the location in the longitudinal direction of the inner deck 32. In this way, a specific location on the escalator can be indicated to passengers by varying 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. For example, the brightness of the light emitted by the first light-emitting device 7 of the inner lighting device 4 on each of the upper and lower floors may be brighter than the brightness of the light emitted by the first light-emitting device 7 of the inner lighting device 4 in the intermediate portion between the upper and lower floors. In this way, the areas around the entrances and exits can be brightly illuminated, and the entrances on the upper and lower floors can be indicated to passengers.

[0084] 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 exterior lighting device 5 may be varied depending on the location in the longitudinal direction of the exterior deck 33. In this way, a specific location on the escalator can be indicated 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 exterior lighting device 5.

[0085] In each of the above embodiments, light from the first light-emitting device 7 of at least one of the inner lighting device 4 and the outer lighting device 5 may be directed toward the side surface of the balustrade panel 2, and the light from the first light-emitting device 7 may be scattered by the side surface of the balustrade panel 2. In this way, the effect of indirect lighting can be obtained by at least one of the inner lighting device 4 and the outer lighting device 5.

[0086] In each of the above embodiments, the balustrade device 1 with lighting functions, including the inside lighting device 4 and the outside lighting device 5, is applied to an escalator. However, the balustrade device 1 with lighting functions, including the inside lighting device 4 and the outside lighting device 5, may also be applied to a moving walkway as a passenger conveyor.
