Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a parapet lighting device for a passenger conveyor such as an escalator or a moving walkway (auto line), and in particular to a parapet lighting device for a passenger conveyor that improves the maintainability of the parapet lighting section. Related to a parapet lighting device.

[Background of the invention]

In addition to high safety as a passenger transport facility, passenger conveyors require parts replacement and maintenance to maintain high functionality.
High overall performance is required, including ease of refueling and maintainability, and in the case of passenger conveyors, structural improvements are particularly desired in terms of maintenance of the parapet lighting section.

As shown in Fig. 1, the parapet 3 of a conventional passenger conveyor consists of a glass panel 4 standing upright between steps 1 arranged in an endless manner for carrying passengers 1 and a moving handrail 2 that rotates in synchronization with the steps. However, as is well known, the glass panel 4 is composed of a parapet frame 5 covering the upper end thereof, a lamp 6, etc., and the entire structure is mounted on the building floor F. Further, inside the handrail frame 5, there is a push plate 8 which is laterally moved by tightening the bolt 7 via a gasket 6 that protects the upper end of the glass panel 4, and which grips the glass panel 4 at this time. , the groove 8a of this push plate 8 and the handle frame 5
In addition to housing a lighting cover 9 to be inserted into the groove 5a, wiring 10 for the lamp 6, etc.
An inner deck 11 and an outer deck 12 are arranged at the lower base of the glass panel 4.

Here, the ones with hatching are arranged continuously along the entire length of the passenger conveyor, but the steps 1 and ramps 6 without hatching are also arranged continuously with a slight gap from each other. In addition to informing the surroundings of the existence of the passenger conveyor with the light beam _K1 of the lamp 6, the light beam _K2 is configured to illuminate the feet of the passengers on the steps 1, contributing to safe use.

The above parapet configuration is the most standard, but
Of this parapet 3, especially the life of the lamp 6 (bulb burnout)
It has been pointed out that the replacement work is difficult due to this, and improvements are desired. That is, the lifespan of the lamp 6 is generally about several hundred to 2,000 hours, but when replacing it, it is necessary to remove the cover 9, remove the lamp 6 from the socket (not shown), and reinstall it. While looking up at the back side of the moving handrail 2 from below, the maintenance worker or administrator also looks up the back side of the handrail frame 5.
Requires work in a narrow space inside.

[Purpose of the invention]

An object of the present invention is to eliminate the inefficient work that is repeatedly performed every time a bulb runs out on a daily basis, without interfering with the safe use of the vehicle by passengers.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 3, the present invention provides a parapet illumination device below the parapet on an outer deck 13 (equivalent to the conventional outer deck 12).
A lamp 15 is provided along the entire length inside the railing, and the railing frame 14 (corresponding to the conventional railing frame 5) above the parapet has two reflective surfaces that reflect the light from inside the outer deck 13 located below. 14
The feature is that a and 14b are provided. In this case, a light-transmitting hole 13a is provided on the upper surface of the outer deck 13 in accordance with the length of the lamp 15 in the entire length direction of the passenger conveyor, and the hole 13a is further covered with a light-transmitting cover 16. It's summery. The reflective surfaces 14a and 14b reflect the light ray _K3 of the lamp 15 outward as a light ray K4 and pass through the glass panel ₄ and reflect it inward as a light ray _K5 , thereby displaying the presence of the passenger conveyor in the surrounding area. , which illuminates one side of the steps to make it safer for passengers to use.

The reflective surfaces 14a and 14b are the handrail frame 1
Although the lower surface of 4 is processed to have a mirror surface, it is also possible to increase the reflection effect by adding a reflector H such as mirror glass or a stainless steel mirror plate, as shown by the two-dot chain line in FIG.

In addition, when replacing the lamp 15 in the above-mentioned parapet configuration, it is possible to work downward from above the building floor F, which not only reduces the labor of maintenance personnel and managers, but also
The internal structure of the handrail frame 14 is extremely simplified as shown in the figure, and since the wiring 16 can be routed through the main body of the passenger conveyor, this wiring work is also extremely simple.

Furthermore, since the lamp 15 is placed on the side of the outer deck 13, passengers will not be able to look directly at the light source even if they look at their feet, and there will be no danger of unsafe boarding and alighting operations due to glare. . Furthermore, since the inside of the outer deck 13 has comparatively more room for installing equipment than the inside of the inner deck 11, the arrangement of the lamps 15 is not a problem and maintenance of the lamps is also facilitated.

By the way, in order to brighten the stair surface and improve the safety of passengers, a lighting device in which a light emitting body is disposed inside the inner deck and all or part of the inner deck is made of a transparent material has been proposed, for example, in 1983. As stated in Publication No. 97794, in this case, since the light source is near the feet of the passenger, when getting on and off the passenger, the user has to look directly at the light source to look at his or her feet, making it unsafe to get on and off due to the glare. Furthermore, since safety equipment is installed inside the inner deck, it is difficult to install a light source inside the inner deck.

〔Effect of the invention〕

According to the present invention described above, the passenger conveyor balustrade illumination can improve maintainability without compromising passenger safety, and is also significantly different from the conventional balustrade structure and exhibits a unique design. equipment can be provided.
