Detailed Description

Hereinafter, the skirt panel lighting device according to the embodiment will be described in detail with reference to the drawings. In addition, the components in this embodiment include components that can be easily replaced by those skilled in the art or substantially the same components, and the present invention is not limited to the following embodiments.

< embodiment >

Fig. 1 is an exemplary and schematic view showing a state in which an escalator 10 as an example of a passenger conveyor on which an apron panel lighting device of the embodiment can be mounted looks up from a lower floor to an upper floor. In addition, fig. 2 is an exemplary and schematic side view illustrating the escalator 10 of fig. 1.

In fig. 1 and 2, an escalator 10 is configured by annularly connecting a plurality of steps 12 (also referred to as steps) and driving the plurality of steps 12 in turns to form a moving path 14. An inlet/outlet plate 18 is provided on the floor surface at the front (upper layer) and the rear (lower layer) of the moving path 14 with respect to the inlet/outlet portion 16 of the moving path 14. An underfloor space 20 (see fig. 2) accommodating a drive mechanism (not shown) for driving the moving path 14 around a circle is formed below the floor of the entrance/exit portion 16. The drive mechanism includes a motor, a drive chain hung between a drive-side sprocket and a driven-side sprocket that are rotationally driven via a speed reducer or the like, and the like. Then, the plurality of steps 12 connected to the drive chain are driven by winding to move the moving path 14, and passengers or cargoes riding on the steps 12 are transported between the upper and lower floors. The underfloor space 20 accommodating the driving mechanism is defined by trusses (structural frames (not shown)) disposed across the upper and lower floors of the building. Further, the driving mechanism and the like are supported and fixed by the truss. The entrance plate 18 covers an opening of the underfloor space 20 provided in the entrance 16, and is fixed by, for example, bolts 18a to close the opening of the underfloor space 20. For example, when the escalator 10 is serviced, the entry panel 18 is detached when the operation of the escalator 10 is stopped, and the maintenance work or the like can be performed.

As shown in fig. 1, a skirt panel 22 extending in the moving direction of the steps 12 and an inner side cover panel 26 covering the upper portion of the skirt panel 22 on the side of the steps 12 with respect to the balustrade 24 are provided at positions adjacent to both sides in the width direction of the steps 12 (the direction substantially perpendicular to the moving direction of the moving path 14). In a space SP (see fig. 3) covered by the skirt panel 22, the inner side panel 26, and the like, a structure for supporting the balustrade 24, a moving mechanism for moving the handrail 24a around the balustrade 24 in synchronization with the movement of the steps 12, and the like are housed, and a moving space for moving the handrail 24a is formed. Further, a glass panel such as tempered glass or a metal panel such as stainless steel is disposed at a lower portion of the moving handrail 24a of the balustrade 24, and the moving path 14 on which the steps 12 move is separated from an area outside the moving path, thereby defining a space as the moving path 14.

The present embodiment includes an apron lighting device M extending in the moving direction of the moving path 14 and illuminating the moving path 14 so as to face the steps 12. As shown in fig. 1 and 2, for example, the skirt panel lighting device M includes a light guide member 28, and the light guide member 28 includes a convex curved surface extending in the moving direction of the moving path 14, facing the step 12, and protruding from the skirt panel 22. A light Emitting surface of a light source, for example, an led (light Emitting diode) is connected to a part of the light guide member 28, and the light guided inside the light guide member 28 illuminates the moving path 14. The light emitted from the skirt panel lighting device M may be in a warm color such as orange or a cool color such as white, for the purpose of improving safety under the feet by emitting the light under the feet of the passenger riding on the steps 12. In addition, colors such as red, yellow, blue, and green may be used to enhance entertainment.

Fig. 3 is an exemplary and schematic sectional view showing an arrangement example of the light guide member 28 and the light source 30 constituting the skirt panel lighting device M and a peripheral configuration of the skirt panel lighting device M.

As described above, the apron illuminating device M is accommodated in the space SP formed by the apron 22, the inner side cover 26, and the like, that is, 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 astride the upper and lower floors of a building in which the escalator 10 is installed, via a spacer 34 by a fastener such as a bolt 38. The bracket 36 is also made of steel or the like. The bracket 36 includes, for example, a balustrade support 36a that supports the glass panel 24b, an inner decking support 36b that supports the inner decking 26, and an outer decking support 36c that supports the outer decking 40 on the opposite side across the balustrade 24, and is disposed along the balustrade 24 from the lower layer toward the upper layer. 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 (the moving direction of the steps 12), or may be a block-shaped member that supports a part of the glass panel 24b at a plurality of positions (for example, at 1m intervals).

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

The inner panel support 36b includes a panel support plate 36b1, and the inner panel 26 as an outer panel (decorative panel) is fixed to the inner panel support 36b by a fastener such as a bolt 44 so as to cover the panel support plate 36b 1. For example, the inner cover 26 may be formed by bending a metal plate such as a stainless steel plate.

The outer cover 40 may be formed by bending a metal plate such as a stainless steel plate. The leg 40a having a substantially C-shaped cross section is connected to the back surface of the outer cover 40 by a joining method such as welding. A fixing plate 46 having a screw portion 46a is inserted into the hollow inner space of the leg portion 40 a. The screw portion 46a protrudes from the opening portion 40a1 of the leg portion 40a, and is inserted through the notch portion 36c1 formed in the outer panel support portion 36 c. The threaded portion 46a is screwed to a nut 48 on the back side of the outer cover support portion 36 c. Therefore, the leg portion 40a and the outer cover support portion 36c are fastened together by the fixing plate 46, and the outer cover 40 is fixed to the outer cover support portion 36 c.

The skirt panel 22 may be an exterior plate (decorative plate) made of a metal plate such as a stainless steel plate, and the screw portion 50 is connected to the back surface of the skirt panel 22 by welding or the like. The screw portion 50 is inserted into a notch portion (not shown) formed in a part of the truss 52 and fixed by a fastener such as a nut 54.

As shown in fig. 3, a support 56 is provided on the upper rear surface of the skirt panel 22 to support a part of the light guide member 28 so that the part of the light guide member 28 protrudes from, for example, the upper end 22a of the skirt panel 22 toward the step 12 side. The bracket 56 includes a first bracket 56a and a second bracket 56 b. The first holder 56a supports the lower end side of the light guide member 28, and vertically positions and fixes the light guide member. The second support 56b positions and fixes the light guide member 28 in the width direction of the step 12 by sandwiching a part of the light guide member 28 between the rear surfaces of the skirt panels 22. A spacer member 58 interposed between the upper end of the light guide member 28 and the lower end of the inner cover 26 is attached to the upper end of the light guide member 28, and the light guide member 28 is supported by the skirt panel 22 and the inner cover 26. The pad member 58 can be formed of a material such as synthetic resin or rubber, or a metal.

An exemplary and schematically enlarged cross-sectional view of the light guide member 28 and its surrounding components is shown in fig. 4. The light guide member 28 is a member formed by cutting or molding a light-transmitting material such as acrylic resin, and has a long dimension extending in the moving direction of the step 12 as shown in fig. 1, for example. In consideration of the capability of the manufacturing apparatus of the light guide member 28 and the operability of storage, transportation, and the like of the light guide member 28, the length of the light guide member 28 in the moving direction of the steps 12 may be, for example, about 1m, and the light guide member may be joined together in the moving direction of the steps 12 according to the length of the moving path 14, or may be formed as an integral long member. As shown in fig. 2, the light guide member 28 includes: a curved light guide member 28r curved at a position near the entrance and exit portion 16; and a linear light guide member 28s sandwiched between the curved light guide member 28r on the lower layer side and the curved light guide member 28r on the upper layer side. The curved light guide 28r and the linear light guide 28s may be formed separately. In this case, as shown in fig. 5, the curved light-guiding member 28r may be a long curved light-guiding member 28rL having a long length, or the curved light-guiding member 28r may be a short curved light-guiding member 28rS divided into a plurality of segments. By configuring the light guide member 28 as a long continuous structure, the seams are less likely to appear during lighting, and high-quality lighting can be achieved. On the other hand, the structure in which the light guide member 28 is divided has the following advantages: the curved shape of the light guide member 28 can be easily adapted to the specifications of each escalator 10, and the light guide member 28 can be easily manufactured as compared with a long light guide member, and can be easily stored and transported. Further, as shown in fig. 5, since the curved light-guiding member 28r has a fixed length, even when the light sources 30 (LEDs and the like) are arranged at fixed intervals, the lights from the respective light sources 30 can be mixed to make the illuminance uniform. As a result, even when the curved light guide members 28r are joined together, it is difficult for variations in illuminance to appear at the seams, and stable illumination can be performed. The same applies to the linear light guide 28 s.

As shown in fig. 4, the light guide member 28 includes: a lower light guide portion 28a supported by the holder 56; a convex curved surface formed to expose the light guide portion 28b and protrude from the skirt panel 22 toward the step 12; an upper light guide portion 28c supported by the spacer member 58; and a rear light guide 28d formed on a flat surface opposite to the convex curved surface.

The light guide member 28 is provided with a light source 30 at a position where light can enter and illuminate the step 12 side through the light guide member 28 (exposing the light guide portion 28b), at least a part of a surface other than the convex curved surface exposing the light guide portion 28 b. In the case of fig. 4, the light source 30 is disposed such that its light-emitting surface faces the lower light guide part 28a with a very small gap therebetween. Although not shown in fig. 4, the lower light guide part 28a and the light source 30 are integrated with each other by a cover (a metal or resin holder), for example. The light source 30 and the light guide member 28 (lower end light guide portion 28a) may be connected without providing a gap therebetween. The lower light guide 28a may be formed in a rectangular shape having a flat support surface so as to be stably supported by the skirt panel 22 and the support 56.

The light source 30 is, for example, a long light emitting strip in which a plurality of LED elements are arranged on a flexible substrate and which extends from a lower layer to an upper layer. When the light guide member 28 is divided into a plurality of parts, the light sources 30 may be divided at the divided positions, 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 multiple times inside the light guide member 28, and exits from the convex curved surface where the light guide portion 28b is exposed, thereby illuminating the steps 12. Although not shown in fig. 3, the power supply and the light emission control unit are connected to the light source 30. The light source 30 may be constantly illuminated when the escalator 10 can be operated, or may change the brightness (illuminance) according to the operation time period. Further, there is an escalator 10 capable of performing passenger detection control in which steps 12 are moved when a passenger enters a predetermined area including a moving path 14. In this case, the light source 30 can be controlled to be turned on or off according to the movement of the step 12.

As described above, the light guide member 28 includes the exposed light guide portion 28b formed to protrude from the skirt panel 22 toward the step 12 side. Therefore, the light of the light source 30, which is emitted from the light source 30 and guided inside the light guide member 28 including the lower end light guide portion 28a, is radially emitted in accordance with the shape of the convex curved surface exposing the light guide portion 28 b. As a result, the steps 12 can be illuminated over a wide range. A diffusion member 60 for diffusing the guided light is provided on the surface of the convex curved surface where the light guide portion 28b is exposed. The diffusion member 60 may be formed of a light-transmitting sheet on which a dot pattern is printed, an uneven pattern is formed, or the like, for example, and diffuses light guided to the exposed light guide portion 28b in a wider range. The diffusion member 60 can adjust the diffusion direction of light by a dot pattern or a concave-convex formation pattern. For example, the first dose L1 for illuminating the step surface of the step 12 may be made larger than the second dose L2 for illuminating the area above the step surface. By increasing the illuminance by making the first irradiation amount L1 for illuminating the steps 12 relatively larger than the second irradiation amount L2, the feet of the passenger riding on the steps 12 can be seen more easily. That is, the standing position on the steps 12 can be more easily recognized, contributing to improvement of safety. For example, the standing position with respect to the riser that is the rising portion of the skirt panel 22 or the step can be more easily confirmed. 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 a feeling of dazzling to the passengers riding on the steps 12.

In addition, the exposed light guide portions 28b can be illuminated by projecting a fixed amount from the surface of the skirt panel 22 to the step 12 side, so as not to come too close to the skirt panel 22. The diffusion member 60 may be formed by coating, vapor deposition, or the like. The first illumination amount L1 and the second illumination amount L2 may be adjusted by adjusting the shape of the exposed light guide portion 28 b. In this case, the diffusion member 60 may be omitted.

Further, although the upper light guide part 28c is formed in a small-sized projection shape for engaging with the pad member 58, for example, the light source 30 may be disposed on the upper light guide part 28c side, and in this case, the upper light guide part 28c may be formed in a wide (wide) rectangular shape, similarly to the lower light guide part 28 a. The light source 30 may be connected to the rear light guide part 28d, but the light of the light source 30 can be prevented from being directly emitted from the exposed light guide part 28b by disposing the light source at the lower end light guide part 28a and the upper end light guide part 28c which do not face the exposed light guide part 28b for emitting light. That is, indirect light can be emitted from the exposed light guide portions 28 b. By disposing the light source 30 in a portion other than the rear light guide portion 28d, for example, a portion of the light guide portion 28b exposed to light can be easily prevented from being brightened in a spot manner.

In the present embodiment, the front surface of the rear light guide part 28d includes a reflecting 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 an opaque sheet or a mirror sheet. By making the rear light guide 28d flat, the reflecting member 62 can be easily disposed, and light leakage can be easily performed. By forming the reflecting member 62 on the front surface of the rear light guide portion 28d, the light emitted from the light source 30 can be efficiently guided to the exposed light guide portion 28b and emitted toward the step 12 side. The light guide member 28 may be formed by coating, vapor deposition, or the like.

In this way, the skirt 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 to the skirt panel 22 adjacent to the end in the width direction of the step 12 of the escalator 10 and extending in the moving direction of the step 12. The light guide member 28 includes a convex curved surface extending in the moving direction, facing the step 12 and protruding from the skirt panel 22, and a flat surface formed on the opposite side of the convex curved surface. The light source 30 is provided so as to be able to illuminate the steps 12 through the light guide member 28 from at least a part of the surface of the light guide member 28 other than the convexly curved surface. According to this configuration, the light from the light source can be diffused over a wide range toward the step 12 side by the convex curved surface that faces the step 12 and protrudes from the skirt panel 22, for example, when the step 12 is illuminated. As a result, for example, even when the light guide member 28 is exposed to a small extent, the steps 12 can be illuminated effectively. Further, the light guide member 28 can be downsized, the supporting structure for supporting the light guide member 28 can be downsized and simplified, and the entire skirt panel lighting device M can be downsized. Therefore, the arrangement space of the apron panel lighting device M can be narrowed. As a result, for example, the skirt panel lighting device M can be applied to an escalator of a narrow width type (narrow width) in which the space SP in fig. 3 is also narrow. That is, the common skirt panel lighting device M can be used regardless of the standard type or the narrow type. Therefore, the universality of the skirt panel lighting device M can be improved.

The light source 30 of the skirt panel illumination device M according to the present embodiment may be disposed, for example, on the lower surface of the light guide member 28. This structure can contribute to the reduction in the dimension in the width direction of the steps 12 of the skirt panel lighting apparatus M. As a result, the skirt panel lighting device M can be easily applied regardless of the standard type or the narrow type.

In addition, the above-mentioned apron panel lighting device M is explained as applied to the escalator 10. As another embodiment, the skirt panel lighting device M described above may 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, the present invention can be applied to a passenger conveyor in which some steps 12 of the moving path 14 move horizontally or in which ascending and descending are mixed in the middle of the moving path 14, and similar effects can be obtained. In the example shown in fig. 3 and 4, the light guide member 28 is projected (exposed) from the upper end of the skirt panel 22. In other embodiments, the light guide member 28 may be protruded (exposed) from a position between the height directions of the skirt panel 22, and similar effects can be obtained.

Although the embodiments of the present invention have been described above, these embodiments are provided as examples, and are not intended to limit the scope of the present invention. These embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the present invention. These embodiments and modifications are included in the scope and spirit of the present invention, and are included in the scope of the present invention and the equivalents thereof described in the claims.
