Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an escalator.

[0002]

2. Description of the Related Art FIG. 3 is a partial vertical cross-sectional view showing a mounting state of a fluorescent lamp which is attached to a lower portion of a deck of a conventional escalator and illuminates a balustrade (not shown). FIG. 4 is an enlarged view of FIG. FIG.

In FIGS. 3 and 4, a handrail rail 13 having a substantially convex cross section is attached by bolts 12 to the upper end of a deck 4 of aluminum stamping material provided on the upper part of a balustrade (not shown). On the other hand, on the lower surface of the deck 4, a pair of supports 3 formed in a substantially Z shape are symmetrically arranged in FIG. 3, and are fastened together with the handrail rail 13 by the bolts 12 described above.

The upper surfaces of the lamp supports 2 in the form of fuse clips contact the lower surfaces of the pair of supports 3 and are fixed to the supports 3 by pan head screws 2a. Inside these lamp supports 2, a fluorescent lamp 1 for balustrade lighting is inserted from below, and is held by the spring force of the lamp supports 2. A lamp socket 7 is inserted into the left and right ends of the fluorescent lamp 1, and a connecting line of the fluorescent lamp 1 is drawn out from the center of the lamp socket 7 and connected to an external power source.

These decks 4 are attached to the upper portion of a truss (not shown) and follow the inclination angle (about 30 °) of the truss installed between the upper floor and the lower floor. For example, the right side in FIG. 3 is the upper floor. If it is a side, the left side is the lower floor side, and the fluorescent lamp 1 is also attached to the right side at the upper side and the left side at the lower side at an inclination angle of 30 °.

[0006]

However, in the escalator configured as described above, the deck 4 also vibrates due to the vibration transmitted from the step plate which drives the truss endlessly together with the step chain (not shown), and The vibration is also transmitted to the support 3, and the lamp support 2 also vibrates.

Then, the fluorescent lamp 1 whose both sides are held by the support 2 gradually moves to the left side, which is the lower floor side in FIG. 3, during the long-term operation of the escalator. As a result, if the right end of the right support 2 in FIG. 3 contacts the left end of the right lamp socket 7, there is a possibility that the lamp socket 7 will come out of the right end of the fluorescent lamp 1 due to the continuously generated vibration. If it is completely removed, there is a possibility that the charging portion at the right end of the fluorescent lamp 1 may come into contact with the support 2 and cause a ground fault.

[0008] Therefore, the maintenance personnel should have a fluorescent light 1
The fluorescent lamps 1 are installed at the bottoms of the left and right decks 4 about 6 each, and the number of inspection items increases, so the inspection time becomes longer and the limited inspection time There is also a risk that inspection will not be possible.

Therefore, an object of the present invention is to obtain an escalator which can reduce the inspection time.

The other side is provided with a stopper that engages with the lower end of the lighting fixture.

According to a second aspect of the present invention, in an escalator in which a tubular illuminator is arranged via a pair of clips provided in the lower part of the balustrade deck, one side is fixed to the deck and the other side is illuminated. It is characterized in that a stopper that engages with an end of the fixture on the lower floor side and a retainer that is fixed to the deck on one side and presses the end of the lighting fixture on the upper floor side are provided.

[0012]

According to the first aspect of the invention, the stopper prevents the illuminator that vibrates due to the vibration generated by the operation of the escalator from moving downward.

Further, in the invention described in claim 2,
The position of the illuminator that vibrates due to the vibration generated by the operation of the escalator is prevented by the stopper and the retainer.
