Abstract

<P>PROBLEM TO BE SOLVED: To provide a passenger conveyor capable of preventing the presence of a light source inside thereof from being visually observed from an illumination cover, and suppressing occurrence of any illumination uniformity. <P>SOLUTION: The parapet illumination 7 is constituted so that the light from a light source 14 is emitted from an illumination cover 13 via a light dispersion means 15. Since the light emitted from the light source 14 is not emitted directly from the illumination cover 13, the presence of the light source inside thereof is not visually observed through the illumination cover 13. Further, since the light from the light source 14 is dispersed by the light dispersion means 15, occurrence of illumination uniformity on the illumination cover 13 can be suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to passenger conveyors such as escalators and electric roads, and more particularly to passenger conveyors equipped with balustrade lighting.

  As a passenger conveyor provided with balustrade lighting, for example, an invention as described in Patent Document 1 has already been proposed.

JP 11-193193 A

  The conventional balustrade illumination uses a light emitting element as a light source. By using the light emitting element, there is an advantage that the number of times of maintenance and inspection of the light source can be reduced as compared with the case where a light bulb or a fluorescent lamp is used as the light source.

  However, when a light emitting element is used as a light source, there is a problem that when the amount of light is increased, the presence of the internal light source can be seen through the illumination cover in a normal usage state, and illuminance spots are generated in the illumination cover.

  An object of the present invention is to provide a passenger conveyor that does not allow visual observation of the presence of an internal light source from a lighting cover in a normal use state and that can suppress the occurrence of illuminance spots.

  In order to achieve the above object, the balustrade illumination is configured such that light from the light source radiates from the illumination cover via the light dispersion means.

  With the above configuration, light emitted from the light source is not directly emitted from the lighting cover, and therefore the presence of the internal light source cannot be visually observed through the lighting cover in a normal use state. Moreover, since the light from a light source is disperse | distributed by a light dispersion | distribution means, it can suppress that an illumination spot produces on a lighting cover.

  Hereinafter, an embodiment of a passenger conveyor according to the present invention will be described based on the electric road shown in FIGS.

  The electric road 1 includes a frame 3 installed between the floors 2A and 2B that are separated from each other, and a step board 4 that is circulated and connected between the boarding and unloading floors 3A and 3B of the frame 3 in a plurality of ways. The balustrade 5 erected along both sides of the direction of movement of the footboard 4, the moving handrail 6 that is guided by the peripheral edge of the balustrade 5 and moves at a synchronous speed, and the balustrade near the moving handrail 6 And balustrade lighting 7 provided at 5.

  The balustrade 5 includes a balustrade panel 8 made of a glass panel or the like that is fixed to the frame 3 at the lower side, a moving handrail frame 9 fixed to the upper end of the balustrade panel 8, and the moving handrail. A guide member 11 supported on a top of the frame body 9 via a support 10 and slidingly guiding the movable handrail 6; and a lower member 12 covering the lower part of the balustrade panel 8 and partitioning the tread plate 4 is provided. Yes.

  The balustrade lighting 7 includes a milky white translucent lighting cover 13 projecting downward from a downward opening formed in the moving handrail frame 9, and an inner side of the lighting cover 13 or the moving handrail frame 9. The light source 14 supported by the inner fixed portion of the light source and the light dispersion supported by the inner fixed portion of the illumination cover 13 or the inner side of the moving handrail frame 9 to diffusely reflect the light from the light source 14 into indirect light. And a concave mirror (reflector) 15 as means. In addition, the light source 14 is installed so as to face the upper side of the frame 9 for the moving handrail, and the concave mirror 15 includes a plurality of concave mirrors 15 so that the light is dispersed without being concentrated in one direction as shown in the figure. It is formed to have a radius of curvature.

  Since the balustrade illumination 7 is configured as described above, the light emitted from the light source 14 is not directly emitted from the illumination cover 13, but is emitted from the illumination cover 13 to the outside after being dispersed by the concave mirror 15. .

  Therefore, the presence of the internal light source 14 is not directly observed through the lighting cover 13. And since the light from the light source 14 passes through the illumination cover 13 after being dispersed, no illuminance spots are generated on the illumination cover 13.

  By the way, although the said embodiment disperse | distributes the light from the light source 14 using the concave mirror 15, it does not use the concave mirror 15, but utilizes the inner surface of the frame 9 for moving handrails as a reflecting member, and is a light source. The light from 14 may be dispersed, and the light may be emitted from the lighting cover 13. With this configuration, the irregular shape of the inner surface of the moving handrail frame 9 with respect to the light source 14 causes light to diffusely reflect and radiate from the illumination cover 13 as indirect light. Can produce various effects. In this case, in order to increase the light reflectivity, the inner surface of the movable handrail frame 9 may be mirror-finished or a white paint having a high light reflectivity may be applied.

  Further, although the concave mirror 15 is used as the light dispersing means in the above embodiment, instead of the concave mirror 15, a metal foil with irregular ridges is used as a reflector to make the inside of the illumination cover 13 or the frame 9 for the moving handrail. You may install inside.

  Furthermore, although the light source 14 is not specified in the above descriptions, the light source 14 may be a light bulb, a fluorescent lamp, or a light emitting element in order to achieve the object of the present invention.

  In addition, for example, a plurality of light emitting elements having a plurality of emission colors may be used as the light source 14, and the plurality of light emitting elements having the plurality of emission colors may be lit alone or in a plurality. By configuring in this way, for example, the electric road is white lighting during normal operation, the electric road is green or blue lighting during energy-saving operation and stopped, and red is used to call attention when passengers are busy By changing the emission color according to the driving state so as to be illuminated, the service of the user can be improved.

  As described above, according to the present embodiment, it is possible to obtain an electric road that does not allow the presence of an internal light source to be seen from the lighting cover and that can suppress the occurrence of illuminance spots.

  In addition, although the above description demonstrated the electrically-driven road as a passenger conveyor, it cannot be overemphasized that this invention is applicable also to an escalator.
