Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for working inside an escalator truss.

[0002]

2. Description of the Related Art Conventionally, during inspection work inside an escalator truss, a portion requiring inspection work is illuminated by a 100W inspection light or a flashlight.

[0003]

In the above-mentioned conventional 100W inspection light, there is a problem that the cord hinders the inspection work, and it is not possible to sufficiently illuminate a narrow place such as the backside of the truss. In addition, in the case of the flashlight, the inspection work is performed with one hand while holding the flashlight with the other hand, so that the inspection workability is deteriorated.

An object of the present invention is to provide a lighting device for working in an escalator truss that can solve the above-mentioned problems with a simple configuration.

[0005]

An object of the present invention is to provide a main body case, a battery housed in the main body case in a replaceable manner, a battery-operated fluorescent lamp housed on a side surface of the main body case, and an end face of the main body case. The battery-powered penlight housed in the main body case, a small mirror provided on the end face of the main body case, a magnet provided on the main body case, one end is fixed to the main body case, and a suction cup is fixed to the other end. This is achieved by employing a configuration consisting of a hanging string and a hanging strap.

According to this configuration, the switch is operated while the main body case is fixed to the truss near the portion requiring inspection by the magnet and the suction cup is attached to the tempered glass of the balustrade or the panel. If the battery-powered fluorescent lamp is turned on, the portion requiring inspection work can be sufficiently illuminated. Also, with the light of this battery-powered fluorescent lamp,
If you can not see enough, for example, to illuminate the back part of the truss, operate the switch to turn on the battery-powered penlight and attach the small mirror so that the light of the battery-powered penlight is sufficiently transmitted By adjusting the angle, the brightness required for the inspection work can be easily obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, an escalator illuminating device for working inside a truss includes a main body case 2 made of a synthetic resin, a battery 3 composed of four AA batteries stored in the main body case 2, and a main body case 2. , One battery-powered penlight 5 housed on the side of the body, one small mirror 6 provided on the end face of the main body case 2, and a magnet 7 provided on the main body case 2.
And one end 8a is fixed to the main body case 2 and the other end 8b
And a switch 10 for turning on and off the battery-powered penlight 5 and the battery-powered fluorescent lamp 4.
Is provided.

The small mirror 6 is attached to the main body case 2 by an adjustment support leg 6A so that the attachment angle can be adjusted. The main body case 2 is about 60 mm × about 1 mm.
The battery-powered fluorescent lamp 4 has a size of 75 mm × about 25 mm and is provided along the side surface in the longitudinal direction. Further, the battery-type fluorescent lamp 4 is covered with a transparent cover 11 that is detachable from the main body case 2. Furthermore, the size of the suction cup 9 is preferably about 80 mm in diameter. The length of the suspension string 8 is preferably about 1000 mm or more.

The switch 10 is connected in series with the battery 3 as shown in FIG. The battery-powered penlight 5 and the battery-powered fluorescent lamp 4 are connected in parallel, and a switch 10
Is connected to the battery 3 alternately in series.

In the above construction, when inspecting the inside of the truss, the suction cup 9 is fixed by suction to tempered glass or a panel constituting the balustrade of the escalator, and the main body case 2 is inspected by a magnet. And fix it to the truss part near the place where After that, if the switch 10 is operated to turn on the battery-type fluorescent lamp 4, it is possible to sufficiently illuminate the portion requiring the inspection work.

If the portion requiring inspection is a narrow portion on the back side of the truss, the switch 10 is operated to turn on the battery-powered penlight 5 and adjust the mounting angle of the small mirror 6. By doing so, if the light from the battery-powered penlight 5 is reflected by the small-sized mirror 6 and sent to a narrow portion on the back side of the truss, it is possible to smoothly perform inspection work in the narrow portion. .

Even if the magnet 7 of the main body case 2 comes off the truss portion, the main body case 2 is not dropped by the suction cup 9 and the hanging string 8.

Further, in the present embodiment, the main body case 2 is fixed to a truss or the like by the magnet 7, so that it is not necessary to hold the main body case 2 and the inspection work can be performed with both hands. Work can be performed efficiently.

[0015]

As described above, according to the present invention, it is possible to sufficiently illuminate the inspection part in a narrow place, and to perform the inspection work with both hands. The lighting equipment for working in the escalator truss that can be planned was obtained.
