Description

Technical Field

[0001] The embodiment relates to a railing lighting alignment jig and a railing lighting mounting method for a passenger conveyor.

Background Art

[0002] In some cases, a railing lighting device is installed on a handrail deck that guides the handrail belt of a passenger conveyor. The railing lighting device is disposed outside the railing that supports the handrail deck (on the side opposite to the steps with respect to the railing) and is formed along the handrail deck. The railing is made of a material having permeability such as glass. Therefore, the illumination from the railing lighting device can be visually recognized by the user through the railing, and the design of the passenger conveyor is improved.

[0003] In some cases, tape-type LEDs are used for the railing lighting device. The tape-type LED is configured such that a plurality of LED light sources arranged at intervals on a tape-shaped base material are accommodated in a resin tube. The tape-type LED is formed in a long shape and is a long light source having flexibility. The tape-type LED is housed inside a lighting case attached to the handrail deck and covered with a cover.

[0004] When attaching the tape-type LED, the operator manually pushes the tape-type LED into the lighting case. More specifically, first, the starting end portion of the tape-type LED is pushed into the lighting case. Then, while the operator moves toward the ending end portion of the tape-type LED, the tape-type LED is sequentially pushed into the lighting case.

[0005] However, since the lighting case is disposed outside the railing, it is difficult to visually recognize the positional relationship between the lighting case and the tape-type LED during the operation. Therefore, it is conceivable that the tape-type LED may be pushed in at a position deviated from the lighting case. In this case, an excessive force may be applied to the tape-type LED, and the tape-type LED may be damaged.

[0011] The passenger conveyor according to this embodiment will be described below with reference to the drawings.

[0012] First, referring to FIG. 1, the passenger conveyor 1 according to this embodiment will be described. Here, as the passenger conveyor 1, an escalator will be described as an example, but the passenger conveyor 1 according to this embodiment may be a moving walkway.

[0013] As shown in FIG. 1, the passenger conveyor 1 includes a plurality of steps 2, a pair of handrails 3, a pair of skirts 4, a pair of handrail decks 5, a pair of handrail belts 6, and a pair of handrail lighting devices 10.

[0014] The steps 2 are connected by an endless step chain (not shown). By driving a driving device not shown, the steps 2 circulate and move between the lower landing 7 and the upper landing 8 while being guided by a guide rail (not shown).

[0015] The handrails 3 are provided vertically on both the left and right sides of the steps 2. The handrails 3 are formed of a member having permeability, for example, formed of glass. The handrails 3 extend from the lower landing 7 to the upper landing 8.

[0016] The skirts 4 cover the lower part of the corresponding handrails ¾ The skirts 4 extend from the lower landing 7 to the upper landing 8 in the same manner as the handrails 3. <![CDATA[ ]]

[0017] The handrail deck 5 extends along the outer peripheral edge of the handrail 3. The handrail deck 5 may extend inside the skirt 4. As shown in FIG. 2, the handrail deck 5 includes two convex portions 5a located on both sides of the handrail 3. The convex portions 5a protrude on the side opposite to the handrail belt 6. In FIG. 2, the convex portions 5a protrude downward. The handrail 3 is inserted between the two convex portions 5a. The handrail deck 5 may also be referred to as a handrail rail.

[0018] As shown in FIG. 1, the handrail belt 6 moves while being guided by the handrail deck 5. The handrail belt 6 circulates and moves in synchronization with the steps 2.

[0019] The railing lighting device 10 is attached along the handrail deck 5. As shown in FIG. 2, the railing lighting device 10 is disposed outside the railing 3 (on the side opposite to the stairs 2 with respect to the railing 3). More specifically, the railing lighting device 10 is attached to the convex portion 5a of the handrail deck 5 located outside the railing 3.

[0020] As shown in FIG. 2, the railing lighting device 10 according to the present embodiment may include a lighting case 11, a cover 12, and a long light source 20.

[0021] The lighting case 11 is supported by the handrail deck 5. The lighting case 11 is fixed to the convex portion 5a of the handrail deck 5. The lighting case 11 may be fixed to the handrail deck 5 with bolts (not shown) or may be attached to the handrail deck 5.

[0022] The lighting case 11 includes a case opening 13 that extends in the longitudinal direction of the handrail deck 5. Although FIG. 2 shows a cross-section of the upper part of the railing 3, in this case, the case opening 13 is formed at the lower part of the lighting case 11. The case opening 13 is configured to be able to insert the long light source 20.

[0023] The long light source 20 is a light source that extends in a long shape. The long light source 20 is housed inside the lighting case 11. The long light source 20 may be a tape-type LED or a tube-type LED. The long light source 20 according to the present embodiment may include a tape-shaped base material 21, a plurality of LED light sources 22 attached on the base material 21, and a tube 23 that houses the base material 21 and the LED light sources 22. The LED light sources 22 are arranged at predetermined intervals along the longitudinal direction of the base material 21.

[0024] The long light source 20 is flexible. The long light source 20 can be mounted along the straight sections (inclined section 5d, horizontal sections 5e, 5f, described later) of the handrail deck 5. The long light source 20 can also be mounted along the handrail deck 5 in arc-shaped or curved sections such as the linear sections 5b, 5c (see Figure 1) of the handrail deck 5. The base material 21 and tube 23 may be made of a flexible material, for example, a resin material. The base material 21 and tube 23 are transparent, allowing light from the LED light source 22 to pass through. The long light source 20 can be configured in any way as long as it is formed in an elongated shape and is flexible, and is not limited to being composed of an LED light source.

[0025] As shown in Figure 2, the cover 12 is positioned on the side of the lighting case 11 opposite to the handrail deck 5. The cover 12 is configured to cover the elongated light source 20 housed inside the lighting case 11. In Figure 2, since the upper cross section of the railing 3 is shown, the cover 12 is positioned below the lighting case 11. The upper end of the cover 12 may engage with the lower end of the lighting case 11. As shown in Figure 2, the cover 12 may be configured to support the elongated light source 20 from below.

[0026] The lighting case 11 and cover 12 may be made of a flexible material, for example, a resin material. The lighting case 11 may have light-shielding properties to block light from the long light source 20 toward the handrail deck 5. The cover 12 may have light-transmitting properties to transmit light from the long light source 20. The lighting case 11 and cover 12 may be divided into multiple sections in the direction along the handrail deck 5.

[0027] As shown in Figure 1, the railing lighting device 10 extends along the railing deck 5. In this embodiment, the railing lighting device 10 may extend through the lower floor's manual section 5b to the interior of the skirt 4, or it may extend through the upper floor's manual section 5c to the interior of the skirt 4. The long light source 20 may be divided into a lower floor's long light source 20A and an upper floor's long light source 20B. The lower floor's long light source 20A extends continuously from the intermediate position MP of the inclined section 5d of the railing deck 5, through the lower floor's manual section 5b to the interior of the skirt 4. The upper floor's long light source 20 extends continuously from the intermediate position MP of the inclined section 5d of the railing deck 5, through the upper floor's manual section 5c to the interior of the skirt 4. The length of the lower floor's long light source 20A and the length of the upper floor's long light source 20B may be equal.

[0028] The long light source 20A on the lower floor and the long light source 20B on the upper floor may be powered by separate power sources. For example, the long light source 20A on the lower floor may be electrically connected to a power supply unit (not shown) housed inside the lower floor end of the skirt 4. The long light source 20B on the upper floor may be electrically connected to a power supply unit (not shown) housed inside the upper floor end of the skirt 4. In the following, the long light source 20A and the long light source 20B will be referred to as the long light source 20.

[0029] Next, the passenger conveyor railing lighting alignment jig according to this embodiment will be described mainly with reference to Figures 3 to 5. The passenger conveyor railing lighting alignment jig (hereinafter referred to as railing lighting alignment jig 30) is a jig for aligning the long light source 20, which is housed inside the lighting case 11 including a case opening 13 that extends in the longitudinal direction of the handrail deck 5, with the case opening 13 of the lighting case 11.

[0030] As shown in Figures 3 and 4, the railing lighting alignment jig 30 includes a housing 40 and a guide roller 60.

[0031] The housing 40 may include a first flat plate portion 41, a second flat plate portion 42, a passage space 43, a light source inlet 44, and a light source outlet 45.

[0032] The first flat plate portion 41 is in contact with the railing 3 when the railing lighting alignment jig 30 is set in the lighting case 11 (see Figure 6). The second flat plate portion 42 has a gripping portion 47, which will be described later, formed thereon so that an operator can grasp the railing lighting alignment jig 30. The first flat plate portion 41 and the second flat plate portion 42 face each other and are formed to follow the longitudinal direction of the railing deck 5 described above. The first flat plate portion 41 and the second flat plate portion 42 are formed along the direction of movement D of the railing lighting alignment jig 30 which follows the longitudinal direction of the railing deck 5. The passage space 43 is formed between the first flat plate portion 41 and the second flat plate portion 42. The passage space 43 is a space for the long light source 20 to pass through.

[0033] The light source inlet 44 is located on one side of the housing 40. The light source inlet 44 is located on one side in the direction of movement D. In the example shown in Figure 3, the long light source 20A on the lower floor side described above is aligned with the case opening 13 of the lighting case 11. In this case, the opening on the left side formed between the first flat plate portion 41 and the second flat plate portion 42 becomes the light source inlet 44. The light source inlet 44 communicates with the passage space 43 and is configured as an inlet for the long light source 20 to enter the passage space 43.

[0034] The light source outlet 45 is located on the other side of the housing 40. The light source outlet 45 is located on the other side in the direction of movement D. In the example shown in Figure 3, the opening on the right side formed between the first flat plate portion 41 and the second flat plate portion 42 is the light source outlet 45. The light source outlet 45 communicates with the passage space 43 and is configured as an outlet for the long light source 20, which is guided by the guide roller 60, to be sent out of the passage space 43.

[0035] Although not shown in the diagram, when aligning the long light source 20B described above with the case opening 13 of the lighting case 11, the opening on the right side shown in Figure 3 becomes the light source inlet 44, and the opening on the left side becomes the light source outlet 45. In this case, the direction of movement D is opposite to the direction shown in Figure 3.

[0036] As shown in Figures 3 and 4, the housing 40 includes a guide portion 46. The guide portion 46 is configured to be insertable into the case opening 13 of the lighting case 11. The guide portion 46 is formed to align with the longitudinal direction (i.e., the direction of movement D) of the handrail deck 5. This allows the first flat plate portion 41 and the second flat plate portion 42 to be positioned along the longitudinal direction of the handrail deck 5 when the guide portion 46 is inserted into the case opening 13 of the lighting case 11.

[0037] The guide portion 46 may be composed of the end portion 41a of the first flat plate portion 41 and the end portion 42a of the second flat plate portion 42. As shown in Figures 3 and 4, the end portion 41a of the first flat plate portion 41 and the end portion 42a of the second flat plate portion 42 may be bent so that they are closer to each other. In a side view of the housing 40 as shown in Figure 4, the housing 40 may be formed in a tapered shape.

[0038] As shown in Figure 3, the housing 40 may include a gripping portion 47. The gripping portion 47 may be formed on the second flat plate portion 42. The gripping portion 47 may be configured to grip the railing lighting alignment jig 30. For example, the gripping portion 47 may be composed of a gripping opening 47a formed on the second flat plate portion 42. In this case, an operator can grip the second flat plate portion 42 using the gripping opening 47a. The gripping opening 47a may be formed in a circular shape. Other examples of the gripping portion 47 include handles or grippers (not shown) that may be attached to the second flat plate portion 42.

[0039] As shown in Figures 3 and 4, the housing 40 may include a connecting portion 48. The connecting portion 48 is configured to detachably connect the first flat plate portion 41 and the second flat plate portion 42. For example, as shown in Figure 5, the connecting portion 48 may include a collar 49, a connecting bolt 50, and a connecting nut 51.

[0040] The collar 49 is interposed between the first flat plate portion 41 and the second flat plate portion 42. The collar 49 may include a through hole 49a. The collar 49 may extend along a central axis, and the through hole 49a may be formed along this central axis. The collar 49 may be formed as a separate part from the first flat plate portion 41 and the second flat plate portion 42.

[0041] The connecting bolt 50 may be inserted through a first bolt hole 41b formed in the first flat plate portion 41, pass through the through hole 49a of the collar 49 and the second bolt hole 42b formed in the second flat plate portion 42, and be fastened to the connecting nut 51. The head portion 50a of the connecting bolt 50 may be housed in the first bolt hole 41b. The connecting bolt 50 may be a countersunk screw, in which case the seating surface of the head portion 50a is tapered and the top surface of the head portion 50a is flat. The first bolt hole 41b formed in the first flat plate portion 41 may be tapered so that the seating surface of the head portion 50a can contact it. The head portion 50a of the connecting bolt 50 does not have to protrude from the first flat plate portion 41. The tip of the connecting bolt 50 protrudes from the second flat plate portion 42, and the male threaded portion 50b formed on the tip of the connecting bolt 50 screws into the female threaded portion (not shown) of the connecting nut 51 that abuts against the second flat plate portion 42. The connecting nut 51 may be fastened to the connecting bolt 50 using a washer 52 and a spring washer 53.

[0042] As shown in Figures 3 and 4, the housing 40 according to this embodiment includes two connecting parts 48. This connects the first flat plate part 41 and the second flat plate part 42, ensuring rigidity. As shown in Figure 3, the two connecting parts 48 may be located on both sides of the gripping part 47. The line segment connecting the two connecting parts 48 may extend in a direction inclined with respect to the direction of movement D. This ensures the rigidity of the housing 40 even when the railing lighting alignment jig 30 is moved along the direction of movement D. Furthermore, the direction in which the line segment connecting the two connecting parts 48 extends can be inclined with respect to the direction in which the housing 40 is inserted into the case opening 13 of the lighting case 11. Therefore, the rigidity of the housing 40 can be ensured even when the housing 40 is inserted into the case opening 13.

[0043] The guide roller 60 is configured to guide the long light source 20 as it passes through the passage space 43. The guide roller 60 is located in the passage space 43. The guide roller 60 is rotatably supported on the second flat plate portion 42 of the housing 40. The guide roller 60 has a rotation axis perpendicular to the second flat plate portion 42 and is configured to guide the long light source 20, which enters from the light source inlet 44, to the light source outlet 45. The guide roller 60 does not necessarily have to be supported on the first flat plate portion 41. When viewed along the rotation axis of the guide roller 60, the guide roller 60 may be formed so as not to protrude from the first flat plate portion 41 and the second flat plate portion 42. The guide roller 60 may be located between the guide portion 46 and the gripping portion 47 of the housing 40.

[0044] As shown in Figure 4, a low-friction sheet 54 may be attached to the surface of the first flat plate portion 41 opposite to the second flat plate portion 42. The low-friction sheet 54 may be made of a material that can reduce friction between the first flat plate portion 41 and the railing 3, or it may be made of any material.

[0045] Next, the method for installing railing lighting according to this embodiment will be described. The railing lighting installation method is a method for housing the long light source 20 in the lighting case 11 using the railing lighting alignment jig 30 described above. The lighting case 11 is attached to the railing deck 5 in advance.

[0046] First, prepare the railing lighting alignment jig 30 described above.

[0047] Next, the long light source 20 is pulled in from the light source inlet 44 of the railing lighting alignment jig 30, passed through the passage space 43, and pulled out from the light source outlet 45. The long light source 20 is pulled out from the roll 20R (see Figure 7) of the long light source 20 which is wound into a roll.

[0048] Next, as shown in Figure 6, the first flat plate portion 41 of the railing lighting alignment jig 30 is brought into contact with the railing 3 that supports the handrail deck 5. The low-friction sheet 54 shown in Figure 4 is omitted in Figure 6, but it is interposed between the first flat plate portion 41 and the railing 3. In this case, the railing lighting alignment jig 30 is positioned at the intermediate position MP of the inclined portion 5d of the handrail deck 5, facing the case opening 13 of the lighting case 11. Here, we will describe the case in which the long light source 20A on the lower floor side is aligned with the case opening 13. In this case, the starting end (one end 20e, see Figure 7) of the long light source 20A is positioned at the intermediate position MP of the inclined portion 5d.

[0049] Next, the guide portion 46 of the railing lighting alignment jig 30 is inserted into the case opening 13 of the lighting case 11. In this case, the railing lighting alignment jig 30 is moved toward the lighting case 11 and the guide portion 46 is inserted into the case opening 13. By inserting the guide portion 46 into the case opening 13 while the first flat plate portion 41 of the housing 40 is in contact with the railing 3, the guide portion 46 can be easily aligned with the case opening 13 and easily inserted into the case opening 13.

[0050] Next, as shown in Figure 7, the railing lighting alignment jig 30 is moved in the direction of movement D, while the long light source 20 is fed out from the light source outlet 45 and pushed into the interior of the lighting case 11 through the case opening 13. During this time, the long light source 20 contacts the guide roller 60 and is guided by the guide roller 60 as it is sent from the light source inlet 44 to the light source outlet 45. Also, since the guide portion 46 of the housing 40 is inserted into the case opening 13 of the lighting case 11, the long light source 20 fed out from the light source outlet 45 is aligned to a position facing the case opening 13. The long light source 20 is then pushed into the interior of the lighting case 11 by an operator. For example, the operator may grasp the gripping portion 47 of the railing lighting alignment jig 30 with one hand and push the long light source 20 into the interior of the lighting case 11 with the other hand. In this way, one operator can house the long light source 20 inside the lighting case 11.

[0051] The railing lighting alignment jig 30 moves from the intermediate position MP (see Figure 1) of the inclined section 5d of the handrail deck 5 toward the lower floor. During this time, the guide section 46 of the housing 40 remains inserted into the case opening 13 of the lighting case 11. As a result, the railing lighting alignment jig 30 moves sequentially from the inclined section 5d of the handrail deck 5 to the horizontal section 5e on the lower floor and the manual section 5b on the lower floor, and the long light source 20 is continuously housed inside the lighting case 11. In the manual section 5b on the lower floor, the railing lighting alignment jig 30 is moved along the arc shape of the manual section 5b.

[0052] When the railing lighting alignment jig 30 reaches the skirt 4, the railing lighting alignment jig 30 is disassembled. In this case, the connecting bolt 50 and connecting nut 51 of the connecting part 48 shown in Figure 5 are removed. As a result, the connecting part 48 is removed, and the first flat plate part 41 and the second flat plate part 42 are separated. Therefore, the long light source 20 can be inserted into the inside of the skirt 4 by itself, and the long light source 20 can be continuously housed inside the lighting case 11 up to the inside of the skirt 4.

[0053] The long light source 20B on the upper floor can also be housed inside the lighting case 11 in the same way as the long light source 20A on the lower floor. That is, the railing lighting alignment jig 30 is moved from the intermediate position MP of the inclined section 5d of the handrail deck 5 toward the upper floor. Then, the railing lighting alignment jig 30 moves sequentially from the inclined section 5d of the handrail deck 5 to the horizontal section 5f on the upper floor and the linear section 5c on the upper floor, so that the long light sources 20 are continuously housed inside the lighting case 11.

[0054] After that, the cover 12 is attached to the lighting case 11, completing the installation of the railing lighting device 10.

[0055] As described above, according to this embodiment, a passage space 43 is formed between the first flat plate portion 41 and the second flat plate portion 42 of the housing 40 through which the long light source 20 passes. The light source inlet 44 of the housing 40 is located on one side of the housing 40, and the light source outlet 45 is located on the other side of the housing 40. The guide portion 46 is insertable into the case opening 13 of the lighting case 11 and is formed to follow the longitudinal direction of the handrail deck 5. As a result, with the guide portion 46 of the housing 40 inserted into the case opening 13, the long light source 20 inserted from the light source inlet 44 is fed out from the light source outlet 45, making it easy to align the long light source 20 with the case opening 13. Therefore, the long light source 20 can be easily pushed into the lighting case 11, and excessive force applied to the long light source 20 can be suppressed. As a result, damage to the long light source 20 can be suppressed.

[0056] Furthermore, according to this embodiment, the guide portion 46 is composed of the end portion 41a of the first flat plate portion 41 and the end portion 42a of the second flat plate portion 42, and the end portion 41a of the first flat plate portion 41 and the end portion 42a of the second flat plate portion 42 are bent so that they are close to each other. As a result, the guide portion 46 can be easily inserted into the case opening 13 of the lighting case 11. Therefore, the work efficiency of the railing lighting installation work can be improved.

[0057] Furthermore, according to this embodiment, the housing 40 includes a connecting portion 48 that detachably connects the first flat plate portion 41 and the second flat plate portion 42. This allows the housing 40 to be constructed from the first flat plate portion 41, the second flat plate portion 42, and the connecting portion 48. As a result, the structure of the housing 40 can be simplified and manufacturing costs can be reduced. In addition, the first flat plate portion 41 and the second flat plate portion 42 can be separated by removing the connecting portion 48. As a result, the railing lighting alignment jig 30 can be easily disassembled.

[0058] Furthermore, according to this embodiment, the connecting portion 48 includes a collar 49 with a through hole 49a interposed between the first flat plate portion 41 and the second flat plate portion 42, a connecting bolt 50, and a connecting nut 51. The connecting bolt 50 is inserted through a first bolt hole 41b formed in the first flat plate portion 41, passes through the through hole 49a in the collar 49 and a second bolt hole 42b formed in the second flat plate portion 42, and is fastened to the connecting nut 51. This simplifies the structure of the connecting portion 48 and reduces manufacturing costs. The connecting portion 48 can also be easily disassembled. As a result, when inserting the long light source 20 into the skirt 4, the railing lighting alignment jig 30 can be easily disassembled, and the long light source 20 can be easily inserted into the skirt 4. Therefore, the work efficiency of railing lighting installation work can be improved.

[0059] Furthermore, according to this embodiment, the head portion 50a of the connecting bolt 50 is housed within the first bolt hole 41b of the first flat plate portion 41. This prevents the head portion 50a from protruding from the first flat plate portion 41. As a result, the first flat plate portion 41 can be brought into contact with the railing 3, and when the railing lighting alignment jig 30 is moved, the head portion 50a of the connecting bolt 50 does not damage the railing 3.

[0060] Furthermore, according to this embodiment, the housing 40 includes a gripping portion 47 formed on the second flat plate portion 42 for gripping the railing lighting alignment jig 30. This allows the railing lighting alignment jig 30 to be easily gripped. As a result, the worker can grip the railing lighting alignment jig 30 with one hand while pushing the long light source 20 into the lighting case 11 with the other hand. This improves the work efficiency of the railing lighting installation work.

[0061] Furthermore, according to this embodiment, the two connecting portions 48 of the housing 40 are located on both sides of the gripping portion 47. This prevents deformation of the second flat plate portion 42 around the gripping portion 47 to which force is applied. As a result, the rigidity of the housing 40 can be increased.

[0062] Furthermore, according to this embodiment, the guide roller 60 is rotatably supported on the second flat plate portion 42. This eliminates the need to support the guide roller 60 on the first flat plate portion 41, simplifying the configuration of the railing lighting alignment jig 30. In addition, the surface of the first flat plate portion 41 facing the railing 3 can be made flat. As a result, the first flat plate portion 41 can be brought into contact with the railing 3, preventing the head portion 50a of the connecting bolt 50 from scratching the railing 3 when the railing lighting alignment jig 30 is moved.

[0063] Furthermore, according to this embodiment, a low-friction sheet 54 is attached to the surface of the first flat plate portion 41 opposite to the second flat plate portion 42. This reduces friction between the first flat plate portion 41 and the railing 3. As a result, the railing lighting alignment jig 30 can be moved smoothly in the direction of movement D, improving the work efficiency of the railing lighting installation work.

[0064] According to the embodiments described above, damage to the long light source 20 can be suppressed.

[0065] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be implemented in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of symbols]
