FIG. 3 is an exemplary and schematic cross-sectional view showing an arrangement example of the light guide member 28 and the light source 30 constituting the skirt guard panel lighting device M and the peripheral structure of the skirt guard panel lighting device M.

As described above, the skirt guard panel lighting device M is housed in the space formed by the skirt guard panel 22 and the inner deck cover 26, that is, the space SP below the balustrade 24.

For example, a bracket 36 for supporting the balustrade 24 is fixed to a truss 32 made of steel or the like provided over the upper and lower floors of a building where the escalator 10 is installed via a spacer 34 by fasteners such as bolts 38. Has been done. The bracket 36 is also made of a steel material or the like. The bracket 36 is arranged along the balustrade 24 from the lower floor to the upper floor, for example, the balustrade support portion 36a supporting the glass panel 24b, the inner deck cover support portion 36b supporting the inner deck cover 26, and the balustrade 24. An outer deck cover support portion 36c or the like that supports the outer deck cover 40 on the opposite side is provided. The bracket 36 may be a long member that supports the entire lower end of the glass panel 24b along the longitudinal direction of the balustrade 24 (moving direction of step 12), or a part of the glass panel 24b. It may be a block-shaped member that supports at a plurality of positions (for example, at 1 m intervals).

As shown in FIG. 3, the balustrade support portion 36a of the bracket 36 includes a groove portion 36a1 having a substantially V-shaped cross section and extending in the longitudinal direction of the balustrade 24. The glass panel 24b is arranged in the groove 36a1 with the lower end region covered with the protective sheet member 24b2 in a state where the cushioning member 24b1 is interposed at the lower end. Then, the glass panel 24b is fixed and supported by the bracket 36 by driving a wedge member 42 having a substantially triangular cross section between the groove portion 36a1 and the glass panel 24b (protective sheet member 24b2).

The inner deck cover support portion 36b includes a cover support plate 36b1, and the inner deck cover 26 as a design plate (decorative plate) is fixed by a fastening member such as a bolt 44 so as to cover the cover support plate 36b1. The inner deck cover 26 can be formed by bending a metal plate such as a stainless steel plate, for example.

The outer deck cover 40 can also be formed by bending a metal plate such as a stainless steel plate. Legs 40a having a substantially C-shaped cross section are connected to the back surface of the outer deck cover 40 by using a joining means such as welding. A fixing plate 46 having a screw portion 46a is inserted into the hollow internal space of the leg portion 40a. The screw portion 46a protrudes from the opening 40a1 of the leg portion 40a and is inserted through the notch portion 36c1 formed in the outer deck cover support portion 36c. Then, the screw portion 46a is screwed with the nut 48 on the back surface side of the outer deck cover support portion 36c. Therefore, the leg portion 40a and the outer deck cover support portion 36c are jointly fastened via the fixing plate 46, and the outer deck cover 40 is fixed to the outer deck cover support portion 36c.

The skirt guard panel 22 is also a design plate (decorative plate) that can be made of a metal plate such as a stainless steel plate, and a screw portion 50 is connected to the back surface by a joining means such as welding. Then, the screw portion 50 is inserted into a notch portion (not shown) formed in a part of the truss 52, and is fixed by a fastening member such as a nut 54.

Further, on the upper back surface of the skirt guard panel 22, as shown in FIG. 3, a bracket 56 that supports a part of the light guide member 28 so as to project from the upper end portion 22a of the skirt guard panel 22 toward the step 12 side, for example. Is provided. The bracket 56 is composed of a first bracket 56a and a second bracket 56b. The first bracket 56a supports the lower end side of the light guide member 28 for vertical positioning and fixing. The second bracket 56b positions and fixes the light guide member 28 in the width direction in step 12 by sandwiching a part of the light guide member 28 on the back surface of the skirt guard panel 22. A packing member 58 sandwiched between the upper end of the light guide member 28 and the lower end of the inner deck cover 26 is mounted on the upper end side of the light guide member 28, and the light guide member 28 is attached to the skirt guard panel 22. And the inner deck cover 26 support it. The packing member 58 can be formed of, for example, a material such as synthetic resin or rubber, or a metal or the like.

FIG. 4 shows an exemplary and schematic enlarged cross-sectional view of the light guide member 28 and its peripheral members. The light guide member 28 is a component formed by, for example, cutting out a translucent material such as acrylic resin or molding a mold, and extends in the moving direction of step 12 as shown in FIG. 1, for example. It is a long part. The length of the light guide member 28 in the moving direction of step 12 is set to, for example, about 1 m in consideration of the capacity of the manufacturing equipment of the light guide member 28 and the handleability of the light guide member 28 such as storage and transportation. Depending on the length of the moving path 14, they may be connected in the moving direction of step 12, or may be formed as an integrated long component. Further, as shown in FIG. 2, the light guide member 28 includes a curved light guide member 28r curved at a position close to the boarding / alighting portion 16, a curved light guide member 28r on the lower floor side, and a curved light guide member 28r on the upper floor side. It is composed of a linear light guide member 28s sandwiched between the 28r and the 28r. The curved light guide member 28r and the linear light guide member 28s may be formed separately. Further, in this case, as shown in FIG. 5, the curved light guide member 28r may be a long curved light guide member 28rL, or the curved light guide member 28r may be further divided into a plurality of short curves. The light guide member 28rS may be used. By forming the light guide member 28 into a long and continuous structure, joints during lighting are less likely to appear, and high-quality lighting is possible. On the other hand, by forming the light guide member 28 into a divided structure, it is easy to correspond to the curved shape of the light guide member 28 for each specification of the escalator 10, and the light guide member 28 can be easily manufactured as compared with a long one. At the same time, it has the advantage of being easy to store and transport. As shown in FIG. 5, since the curved light guide member 28r has a constant length, even when the light sources 30 (LEDs and the like) are arranged at regular intervals, the light from the respective light sources 30 is mixed. It is possible to make the matching illuminance uniform. As a result, even when the curved light guide members 28r are joined together, variations in illuminance are unlikely to appear at the joints, and stable lighting can be performed. The same applies to the linear light guide member 28s.

As shown in FIG. 4, the light guide member 28 includes a lower end light guide portion 28a supported by the bracket 56, an exposed light guide portion 28b forming a convex curved surface protruding from the skirt guard panel 22 on the step 12 side, and packing. It is composed of an upper end light guide portion 28c supported by the member 58 and a back light guide portion 28d forming a flat surface formed on the side opposite to the convex curved surface.

With respect to the light guide member 28, light is incident on at least a part of the surface of the exposed light guide portion 28b excluding the convex curved surface to illuminate the step 12 side via the light guide member 28 (exposed light guide portion 28b). The light source 30 is provided at a position where it can be formed. In the case of FIG. 4, the light source 30 has a light emitting surface facing the lower end light guide portion 28a with a slight gap. Although not shown in FIG. 4, the lower end light guide portion 28a and the light source 30 are integrated by, for example, a cover (metal or resin bracket). The light source 30 and the light guide member 28 (lower end light guide portion 28a) may be connected without providing a gap. The lower end light guide portion 28a can be a rectangle having a flat support surface so that it can be stably supported by the skirt guard panel 22 and the bracket 56.

The light source 30 is, for example, a flexible substrate in which a plurality of LED elements are arranged, and is a long light emitting band extending from the lower floor to the upper floor. When the light guide member 28 is divided into a plurality of parts, the light source 30 may be divided at the divided position, or may be appropriately divided regardless of the division of the light guide member 28. The light emitted from the light source 30 is reflected from the inside of the light guide member 28 a plurality of times to be emitted from the convex curved surface of the exposed light guide unit 28b to illuminate step 12. Although not shown in FIG. 3, a power supply and a light emission control unit are connected to the light source 30. The light source 30 may always emit light when the escalator 10 can be operated, or the brightness (illuminance) may be changed depending on the operating time zone. In addition, there is an escalator 10 capable of executing passenger detection control in which step 12 moves when a passenger enters a predetermined area including a movement path 14. In this case, the lighting and extinguishing of the light source 30 may be controlled according to the presence or absence of movement in step 12.

As described above, the light guide member 28 includes an exposed light guide portion 28b formed so as to project from the skirt guard panel 22 on the step 12 side. Therefore, the light of the light source 30 emitted from the light source 30 and guided inside the light guide member 28 including the lower end light guide portion 28a is emitted radially according to the shape of the convex curved surface of the exposed light guide portion 28b. To. As a result, it becomes possible to illuminate step 12 in a wide range. A diffusion member 60 for diffusing the guided light is provided on the surface of the convex curved surface of the exposed light guide portion 28b. The diffusion member 60 can be composed of, for example, a translucent sheet that has been subjected to dot pattern printing, unevenness processing, or the like, and diffuses the light guided to the exposed light guide portion 28b in a wider range. Further, the diffusion member 60 can adjust the diffusion direction of light by the pattern of the dot pattern and the pattern of forming the unevenness. For example, the first illumination amount L1 that illuminates the step surface of step 12 may be larger than the second illumination amount L2 that illuminates the region above the step surface. By increasing the illuminance by making the first illumination amount L1 that illuminates the step 12 relatively larger than the second illumination amount L2, it is possible to make the feet of the passengers on the step 12 more visible. That is, it is possible to make it easier to recognize the standing position on step 12 and contribute to the improvement of safety. For example, it is possible to make it easier to confirm the standing position of the skirt guard panel 22 and the riser which is the raised portion of the step 12. Further, by making the second illumination amount L2 relatively smaller (darker) than the first illumination amount L1, it is possible to make it difficult to give glare to the passengers who got on the step 12.

Further, by projecting the exposed light guide portion 28b from the surface of the skirt guard panel 22 toward the step 12 side by a certain amount and shining it, it is possible to call attention not to come too close to the skirt guard panel 22. The diffusion member 60 may be formed by coating, thin film deposition, or the like. Further, the adjustment of the first illumination amount L1 and the second illumination amount L2 may be performed by adjusting the shape of the exposed light guide portion 28b. In this case, the diffusion member 60 may be omitted.

The upper end light guide portion 28c has a small protrusion shape for engagement with the packing member 58, but for example, the light source 30 can be arranged on the upper end light guide portion 28c side. In this case, Similar to the lower end light guide portion 28a, the upper end light guide portion 28c may have a wide rectangular shape. The light source 30 may be connected to the rear light guide portion 28d, but by arranging the light source 30 at the lower end light guide portion 28a or the upper end light guide portion 28c that does not face the exposed light guide portion 28b that emits light, the light of the light source 30 Can be avoided to be emitted directly from the exposed light guide unit 28b. That is, indirect light can be emitted from the exposed light guide unit 28b. By arranging the light source 30 in addition to the rear light guide portion 28d, it is possible to easily prevent, for example, a part of the exposed light guide portion 28b from becoming bright spot.

Further, in the case of the present embodiment, the surface of the back light guide portion 28d includes a reflection member 62 that reflects the light guided inside the light guide member 28 toward the convex curved surface side. The reflective member 62 may be a translucent sheet or a mirror surface sheet. By making the rear light guide portion 28d flat, the reflecting member 62 can be easily arranged and light leakage can be easily performed. By forming the reflective member 62 on the surface of the rear light guide unit 28d, the light emitted from the light source 30 can be efficiently guided to the exposed light guide unit 28b and emitted to the step 12 side. The light guide member 28 may be formed by coating, thin film deposition, or the like.

As described above, the skirt guard panel lighting device M of the present embodiment includes the light guide member 28 and the light source 30. The light guide member 28 is provided on the skirt guard panel 22 that is adjacent to the widthwise end of step 12 of the escalator 10 and extends along the moving direction of step 12. The light guide member 28 includes a convex curved surface that extends in the moving direction, faces step 12, and projects from the skirt guard panel 22, and a flat surface formed on the opposite side of the convex curved surface. The light source 30 is provided so that the step 12 can be illuminated from at least a part of the surface of the light guide member 28 excluding the convex curved surface via the light guide member 28. According to this configuration, the convex curved surface facing step 12 and protruding from the skirt guard panel 22 makes it possible to diffuse the light from the light source over a wide range on the step 12 side, for example, when illuminating step 12. Become. As a result, for example, even when the light guide member 28 is exposed to a small amount, the step 12 can be effectively illuminated. Further, the miniaturization of the light guide member 28 makes it possible to miniaturize and simplify the support structure that supports the light guide member 28, which can contribute to the miniaturization of the skirt guard panel lighting device M as a whole. Therefore, the arrangement space of the skirt guard panel lighting device M can be narrowed. As a result, for example, the skirt guard panel lighting device M can be applied to a narrow type escalator having a narrow space SP and a narrow type escalator in FIG. That is, the common skirt guard panel lighting device M can be applied regardless of whether it is a standard type or a narrow type. Therefore, the versatility of the skirt guard panel lighting device M can be improved.

Further, the light source 30 of the skirt guard panel lighting device M of the present embodiment may be arranged on the lower surface of the light guide member 28, for example. According to this configuration, it is possible to contribute to the size reduction in the width direction of step 12 of the skirt guard panel lighting device M. As a result, the application of the skirt guard panel lighting device M becomes easier regardless of whether it is a standard type or a narrow type.

The case where the skirt guard panel lighting device M described above is applied to the escalator 10 has been described. As another embodiment, the skirt guard panel lighting device M described above can be applied to, for example, a moving walkway (so-called moving walkway) as another example of the passenger conveyor, and the same effect can be obtained. Further, it can be applied to a passenger conveyor so that the step 12 moves horizontally in a part of the moving path 14 and the ascending and descending are mixed in the middle of the moving path 14, and the same effect can be obtained. Further, in the examples shown in FIGS. 3 and 4, an example in which the light guide member 28 is projected (exposed) from the upper end portion of the skirt guard panel 22 is shown. In another embodiment, the light guide member 28 may be projected (exposed) from a position between the height directions of the skirt guard panel 22, and the same effect can be obtained.
