Description

[Technical Field]

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

[0002] A balustrade lighting device may be installed on the handrail deck that guides the handrail belt of a passenger conveyor. The balustrade lighting device is placed on the outside of the balustrade that supports the handrail deck (on the opposite side of the balustrade from the steps) and is formed to fit along the handrail deck. The balustrade is made of a transparent material such as glass. This allows the light from the balustrade lighting device to be visible to users through the balustrade, improving the design of the passenger conveyor.

[0003] LED strips are sometimes used for balustrade lighting devices. LED strips are configured so that multiple LED light sources are arranged at intervals on a tape-shaped base material and housed in a resin tube. LED strips are formed in a long, flexible light source. LED strips are housed inside a lighting case attached to the railing deck and covered with a cover.

[0004] When installing LED strips, the worker manually pushes the LED strip into the lighting case. More specifically, the worker first pushes the beginning of the LED strip into the lighting case. Then, the worker moves towards the end of the LED strip, pushing each LED strip into the lighting case one by one.

[0005] However, because the lighting case is located on the outside of the balustrade, it is difficult to visually confirm the relative positions of the lighting case and the LED strip during installation. This means that the LED strip may be pushed into the lighting case at an incorrect position. In this case, excessive force may be applied to the LED strip, potentially damaging it.

[0011] Hereinafter, a passenger conveyor according to this embodiment will be described with reference to the drawings.

[0012] First, a passenger conveyor 1 according to this embodiment will be described with reference to Fig. 1. Here, an escalator will be taken as an example of the passenger conveyor 1, but the passenger conveyor 1 according to this embodiment may also 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 drive device (not shown), the steps 2 move cyclically between the lower floor entrance 7 and the upper floor entrance 8 while being guided by a guide rail (not shown).

[0015] The balustrades 3 are provided vertically on both the left and right sides of the steps 2. The balustrades 3 are made of a transparent material, such as glass. The balustrades 3 extend from the boarding / alighting entrance 7 on the lower floor to the boarding / alighting entrance 8 on the upper floor.

[0016] The skirt 4 covers the lower part of the corresponding balustrade 3. Like the balustrade 3, the skirt 4 extends from the boarding entrance 7 on the lower floor to the boarding entrance 8 on the upper floor.

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

[0018] 1, the handrail belt 6 moves while being guided by the handrail deck 5. The handrail belt 6 moves in synchronization with the steps 2 and in a circular movement with the steps 2.

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

[0020] As shown in FIG. 2, the balustrade lighting device 10 according to this 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 a protrusion 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 extending in the longitudinal direction of the handrail deck 5. Fig. 2 shows a cross section of the upper part of the balustrade 3, and in this case, the case opening 13 is formed in the lower part of the lighting case 11. The case opening 13 is configured so that the long light source 20 can be inserted therein.

[0023] The elongated light source 20 is a light source that extends in an elongated shape. The elongated light source 20 is housed inside the lighting case 11. The elongated light source 20 may be a tape-type LED or a tube-type LED. The elongated light source 20 according to this embodiment may include a tape-shaped base material 21, a plurality of LED light sources 22 attached to 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 elongated light source 20 is flexible. The elongated light source 20 can be attached along the straight portions of the handrail deck 5 (the inclined portions 5d and the horizontal portions 5e and 5f, which will be described later). The elongated light source 20 can also be attached along the handrail deck 5 to portions that are formed in an arc or curved shape, such as the vertical portions 5b and 5c (see FIG. 1) of the handrail deck 5. The base material 21 and the tube 23 may be made of a flexible material, and may be made of a resin material, for example. The base material 21 and the tube 23 are transparent so that light from the LED light source 22 can pass through. The elongated 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 made of an LED light source.

[0025] As shown in FIG. 2, the cover 12 is arranged on the opposite side of the lighting case 11 from the handrail deck 5. The cover 12 is configured to cover the elongated light source 20 housed inside the lighting case 11. Since FIG. 2 shows a cross section of the upper part of the balustrade 3, the cover 12 is arranged below the lighting case 11. The upper end of the cover 12 may be engaged with the lower end of the lighting case 11. As shown in FIG. 2, the cover 12 may be configured to support the elongated light source 20 from below.

[0026] The lighting case 11 and the cover 12 may be made of a flexible material, for example, a resin material. The lighting case 11 may have a light-blocking property that blocks light from the elongated light source 20 toward the handrail deck 5. The cover 12 may have a transparency that allows light from the elongated light source 20 to pass through. The lighting case 11 and the cover 12 may be divided into multiple pieces in the direction along the handrail deck 5.

[0027] As shown in FIG. 1 , the balustrade lighting device 10 extends along the railing deck 5. The balustrade lighting device 10 according to this embodiment may extend through the lower-floor manubrium portion 5b to the inside of the skirt 4, or through the upper-floor manubrium portion 5c to the inside of the skirt 4. The elongated light source 20 may be divided into a lower-floor manubrium light source 20A and an upper-floor manubrium light source 20B. The lower-floor manubrium light source 20A extends continuously from a middle position MP of the sloped portion 5d of the railing deck 5, through the lower-floor manubrium portion 5b, to the inside of the skirt 4. The upper-floor manubrium light source 20 extends continuously from a middle position MP of the sloped portion 5d of the railing deck 5, through the upper-floor manubrium portion 5c, to the inside of the skirt 4. The lengths of the lower-floor manubrium light source 20A and the upper-floor manubrium light source 20B may be equal.

[0028] The elongated light source 20A on the lower floor side and the elongated light source 20B on the upper floor side may be supplied with power from separate power sources. For example, the elongated light source 20A on the lower floor side may be electrically connected to a power supply unit (not shown) housed inside the lower floor end of the skirt 4. The elongated light source 20B on the upper floor side 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 details common to the elongated light source 20A and the elongated light source 20B will be described by referring to them as the elongated light source 20.

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

[0030] As shown in FIGS. 3 and 4, the balustrade 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 abuts against the balustrade 3 when the balustrade lighting positioning jig 30 is set in the lighting case 11 (see FIG. 6). The second flat plate portion 42 is formed with a grip portion 47, which will be described later, so that an operator can grip the balustrade lighting positioning jig 30. The first flat plate portion 41 and the second flat plate portion 42 are formed to face each other and to extend along the longitudinal direction of the handrail deck 5 described above. The first flat plate portion 41 and the second flat plate portion 42 are formed along the movement direction D of the balustrade lighting positioning jig 30, which is along the longitudinal direction of the handrail deck 5. A 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 through which the elongated light source 20 passes.

[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 movement direction D. The example shown in FIG. 3 shows a case where the above-mentioned elongated light source 20A on the lower floor side is aligned with the case opening 13 of the lighting case 11, and in this case, the left opening 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 elongated 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 movement direction D. In the example shown in FIG. 3, the right opening 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 sending out the elongated light source 20 guided by the guide rollers 60 from the passage space 43.

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

[0036] 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 be aligned along the longitudinal direction of the handrail deck 5 (i.e., the movement direction D). As a result, when the guide portion 46 is inserted into the case opening 13 of the lighting case 11, the first flat plate portion 41 and the second flat plate portion 42 can be positioned to be aligned along the longitudinal direction of the handrail deck 5.

[0037] The guide portion 46 may be formed by an end portion 41a of the first flat plate portion 41 and an 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 as to approach each other. In the side view of the housing 40 shown in Figure 4, the housing 40 may be formed in a tapered shape.

[0038] As shown in FIG. 3 , the housing 40 may include a grip portion 47. The grip portion 47 may be formed on the second flat plate portion 42. The grip portion 47 may be configured to grip the balustrade lighting alignment jig 30. For example, the grip portion 47 may be configured as a grip 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 grip opening 47a. The grip opening 47a may be formed in a circular shape. As another example of the grip portion 47, a handle or a grip (not shown) may be attached to the second flat plate portion 42.

[0039] 3 and 4, the housing 40 may include a connecting portion 48. The connecting portion 48 is configured to separably connect the first flat plate portion 41 and the second flat plate portion 42. For example, as shown in FIG. 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 the 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 50a of the connecting bolt 50 may be received in the first bolt hole 41b. The connecting bolt 50 may be a flat head screw, in which case the bearing surface of the head 50a is tapered and the top surface of the head 50a is flat. The first bolt hole 41b formed in the first flat plate portion 41 may be tapered so that the bearing surface of the head 50a can abut against it. The head 50a of the connecting bolt 50 does not have to protrude from the first flat plate portion 41. The tip of connecting bolt 50 protrudes from second plate portion 42, and male thread portion 50b formed at the tip of connecting bolt 50 threadably engages with a female thread portion (not shown) of connecting nut 51 that abuts against second plate portion 42. Connecting nut 51 may be fastened to connecting bolt 50 using washer 52 and spring washer 53.

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

[0043] The guide roller 60 is configured to guide the elongated light source 20 passing through the passage space 43. The guide roller 60 is located in the passage space 43. The guide roller 60 is rotatably supported by 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 send the elongated light source 20 entering from the light source inlet 44 to the light source outlet 45. The guide roller 60 does not have to be supported by 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 grip portion 47 of the housing 40.

[0044] 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 balustrade 3, or may be made of any material.

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

[0046] First, the above-described balustrade lighting positioning jig 30 is prepared.

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

[0048] Next, as shown in FIG. 6, the first flat plate portion 41 of the balustrade lighting positioning jig 30 is abutted against the balustrade 3 supporting the handrail deck 5. Although the low-friction sheet 54 shown in FIG. 4 is omitted in FIG. 6, it is interposed between the first flat plate portion 41 and the balustrade 3. In this case, the balustrade lighting positioning jig 30 is positioned at the middle position MP of the inclined portion 5d of the handrail deck 5, facing the case opening 13 of the lighting case 11. Here, a case will be described in which the elongated light source 20A on the lower floor side is positioned with the case opening 13. In this case, the starting end (one end 20e, see FIG. 7) of the elongated light source 20A is positioned at the middle position MP of the inclined portion 5d.

[0049] Next, the guide portion 46 of the balustrade lighting positioning jig 30 is inserted into the case opening 13 of the lighting case 11. In this case, the balustrade lighting positioning 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 abutted against the balustrade 3, the guide portion 46 can be easily aligned with the case opening 13, and the guide portion 46 can be easily inserted into the case opening 13.

[0050] Next, as shown in FIG. 7 , while moving the balustrade lighting alignment jig 30 in the movement direction D, the elongated light source 20 is fed out from the light source outlet 45 and pushed into the lighting case 11 through the case opening 13. During this movement, the elongated light source 20 comes into contact with the guide rollers 60 and is fed from the light source inlet 44 to the light source outlet 45 while being guided by the guide rollers 60. Furthermore, because the guide portion 46 of the housing 40 is inserted into the case opening 13 of the lighting case 11, the elongated light source 20 fed out from the light source outlet 45 is aligned in a position facing the case opening 13. The elongated light source 20 is pushed into the lighting case 11 by an operator. For example, the operator may hold the grip portion 47 of the balustrade lighting alignment jig 30 with one hand and push the elongated light source 20 into the lighting case 11 with the other hand. This allows the elongated light source 20 to be accommodated in the lighting case 11 by a single operator.

[0051] The balustrade lighting positioning jig 30 moves from the intermediate position MP (see FIG. 1) of the inclined portion 5d of the handrail deck 5 toward the lower floor. During this time, the guide portion 46 of the housing 40 continues to be inserted into the case opening 13 of the lighting case 11. Therefore, the balustrade lighting positioning jig 30 moves sequentially from the inclined portion 5d of the handrail deck 5 to the horizontal portion 5e on the lower floor side and to the manual portion 5b on the lower floor side, and the long light source 20 is continuously accommodated inside the lighting case 11. In the manual portion 5b on the lower floor side, the balustrade lighting positioning jig 30 is moved along the arc shape of the manual portion 5b.

[0052] When the balustrade lighting positioning jig 30 reaches the skirt 4, the balustrade lighting positioning jig 30 is disassembled. In this case, the connecting bolt 50 and connecting nut 51 of the connecting part 48 shown in FIG. 5 are removed. This removes the connecting part 48, and separates the first flat plate part 41 and the second flat plate part 42. Therefore, the elongated light source 20 can be inserted into the skirt 4 by itself, and the elongated light source 20 can be housed inside the lighting case 11 all the way to the inside of the skirt 4.

[0053] The elongated light source 20B on the upper floor side can also be accommodated inside the lighting case 11 in the same manner as the elongated light source 20A on the lower floor side. That is, the balustrade lighting positioning jig 30 is moved toward the upper floor side from the intermediate position MP of the inclined portion 5d of the handrail deck 5. Then, the balustrade lighting positioning jig 30 moves sequentially from the inclined portion 5d of the handrail deck 5 to the horizontal portion 5f on the upper floor side and to the horizontal portion 5c on the upper floor side, and the elongated light sources 20 are consecutively accommodated inside the lighting case 11.

[0054] Thereafter, the cover 12 is attached to the lighting case 11, and the installation of the parapet lighting device 10 is completed.

[0055] As described above, according to the present embodiment, a passage space 43 through which the elongated light source 20 passes is formed between the first flat plate portion 41 and the second flat plate portion 42 of the housing 40. 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 extend along the longitudinal direction of the handrail deck 5. With the guide portion 46 of the housing 40 inserted into the case opening 13, the elongated light source 20 inserted through the light source inlet 44 can be fed out through the light source outlet 45, thereby easily aligning the elongated light source 20 with the case opening 13. Therefore, the elongated light source 20 can be easily pushed into the lighting case 11, preventing excessive force from being applied to the elongated light source 20. As a result, damage to the elongated light source 20 can be prevented.

[0056] Furthermore, according to this embodiment, the guide portion 46 is formed by 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 as to approach each other. This allows the guide portion 46 to be easily inserted into the case opening 13 of the lighting case 11. This improves the work efficiency of the balustrade lighting installation work.

[0057] Furthermore, according to this embodiment, the housing 40 includes a connecting portion 48 that separably connects the first flat plate portion 41 and the second flat plate portion 42. This allows the housing 40 to be configured with the first flat plate portion 41, the second flat plate portion 42, and the connecting portion 48. This simplifies the configuration of the housing 40 and reduces manufacturing costs. Furthermore, the first flat plate portion 41 and the second flat plate portion 42 can be separated by removing the connecting portion 48. This also allows the balustrade lighting alignment jig 30 to be easily disassembled.

[0058] According to this embodiment, the connecting portion 48 includes a collar 49 having 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 the first bolt hole 41b formed in the first flat plate portion 41, passes through the through hole 49a of the collar 49 and the second bolt hole 42b formed in the second flat plate portion 42, and is fastened to the connecting nut 51. This simplifies the configuration of the connecting portion 48 and reduces manufacturing costs. The connecting portion 48 can also be easily disassembled. Therefore, when inserting the elongated light source 20 into the skirt 4, the balustrade lighting positioning jig 30 can be easily disassembled, and the elongated light source 20 can be easily inserted into the skirt 4. This improves the efficiency of the balustrade lighting installation work.

[0059] Furthermore, according to this embodiment, the head portion 50a of the connecting bolt 50 is housed in 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. This allows the first flat plate portion 41 to abut against the balustrade 3, and prevents the head portion 50a of the connecting bolt 50 from damaging the balustrade 3 when the balustrade lighting alignment jig 30 is moved.

[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 balustrade lighting positioning jig 30. This makes it possible to easily grip the balustrade lighting positioning jig 30. Therefore, a worker can hold the balustrade lighting positioning jig 30 with one hand while pushing the elongated light source 20 into the lighting case 11 with the other hand. As a result, the work efficiency of the balustrade lighting installation work can be improved.

[0061] Furthermore, according to the present embodiment, the two connecting portions 48 of the housing 40 are located on both sides of the grip portion 47. This makes it possible to prevent the second flat plate portion 42 from deforming around the grip portion 47 to which force is applied. This increases the rigidity of the housing 40.

[0062] Furthermore, according to this embodiment, the guide roller 60 is rotatably supported by 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 balustrade lighting alignment jig 30. Furthermore, the surface of the first flat plate portion 41 that faces the balustrade 3 can be flattened. This allows the first flat plate portion 41 to abut against the balustrade 3, preventing the head portion 50a of the connecting bolt 50 from damaging the balustrade 3 when the balustrade 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 balustrade 3. This allows the balustrade lighting positioning jig 30 to be moved smoothly in the movement direction D, improving the work efficiency of the balustrade lighting installation work.

[0064] According to the embodiment described above, the long light source 20 can be prevented from being damaged.

[0065] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the inventions and their equivalents as defined in the claims.
