BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work roof device for an outdoor escalator, and more particularly to a work roof device for outdoor elevators and walkways.

[0002]

2. Description of the Related Art In recent years, outdoor escalators and walking sidewalks have been installed at stations and department stores in order to facilitate passenger traffic.

FIG. 9 is a perspective view showing the structure of an outdoor escalator. As shown in FIG. 9, an outdoor escalator and a walking walkway have basically the same structure as an escalator installed indoors. Therefore, the balustrade deck 1 provided with the moving handrails is provided on the left and right sides, and a step for a person to board is provided between the balustrade decks 1 on the left and right sides.

When performing maintenance / inspection work on these outdoor escalators and the like, as in the case of a normal indoor escalator, the escalator is located inside the escalator 2 surrounded by the balustrade deck 1 for steps and movements. Maintenance and inspection work such as handrails is performed.

[0005]

However, the escalator exposed to the outdoors, the balustrade deck 1 of a walking sidewalk, and the escalator inside 2 surrounded by the balustrade deck 1 on the left and right sides are exposed to direct sunlight and reflection of reflected light when the weather is fine. Due to the heat, for example, in the summer, the temperature becomes extremely high (for example, 50 ° C.). On the other hand, in case of rain, workers and tools are exposed to rainfall. That is, depending on the weather, it was necessary to work in a very bad environment.

Therefore, there has been a demand for a work roof which can avoid the sunlight and sudden rainfall in the summer and can be easily detached and carried.

The present invention has been made in view of the above problems, and an object thereof is to provide a work roof device for an outdoor escalator, which can be easily attached to and detached from a balustrade deck of an escalator and which can avoid the influence of severe weather. To provide.

[0008]

In order to solve the above problems, the working roof device for an outdoor escalator according to the present invention has the following features.

(1) A substantially trapezoidal frame standing on all sides,
A sheet member stretched on the frame so as to be a top plate,
And a mounting portion that is detachably mounted on a side surface of a guide rail that is provided at a lower end of the frame and guides a moving direction of a moving handrail of the escalator.

(2) In the work roof device for an outdoor escalator described in (1) above, the two horizontal bars forming the ceiling portion of the frame and crossing the lateral width of the escalator are two lateral bars extending from the left and right respectively. It is composed of a rod and a connecting portion connecting the two rods, and the two rods and the connecting portion are connected so as to be able to expand and contract according to the lateral width of the escalator.

(3) In the work roof device for an outdoor escalator described in (1) above, the horizontal bar is provided with a commercial power source and / or a hanging metal fitting.

[0012]

According to the working roof device for an outdoor escalator according to the present invention constructed as described above, a sheet member is stretched on a substantially trapezoidal frame standing on all sides to form a top plate, and further the frame is formed. Since the mounting part provided at the lower end of the escalator can be detachably attached to the side of the guide rail that guides the moving direction of the escalator's moving handrail, you can carry it with you when carrying out maintenance and inspection work on the outdoor escalator, etc. It is possible to set up a roof for work while moving the place accordingly. For this reason, even in the case of fine weather in the summer, it is possible to avoid direct sunlight, and there is no fear of being exposed to rainfall when it is raining. Therefore, work efficiency is improved.

At that time, as described above, the pushing spring body 11 of the present device 5 is pressed against the outer vertical surface 3a of the guide rail 3 which guides the moving handrail 4 arranged on the balustrade deck 1.

As shown in FIG. 5, the push spring body 11 has an operation knob 11b and a pressure contact portion 1 which is in pressure contact with the vertical surface 3a.
1d and a presser shaft 11c connecting the operation knob 11b and the press contact portion 11d, and the presser shaft 11c has a protrusion 11a.
Are formed. Both ends of the spring 1e are attached to the inner surface of the frame 12 and the press contact portion 11d, respectively.
On the other hand, the circular hole 12a of the frame of the present device 5 described above is formed in such a size that the pressing shaft 11c can penetrate therethrough, and the groove hole 12b.
Is formed so that the protrusion 11a formed on the pressing shaft 11c can pass therethrough. Therefore, as shown in FIG.
The device 5 is mounted on the vertical surface 3a of the guide rail 3 of the escalator.
In the case of attaching the pressing spring body 11 to the inside of the frame 12, the pressing spring body 11 is pushed through the circular hole 12a and the groove hole 12b of the frame 12 so that the protruding portion 11a of the pressing shaft 11c appears. Then, it is rotated and the protrusion 11a is hooked inside the frame 12. As a result, the press contact portion 11
d is pressed against the vertical surface 3a of the guide rail 3 and the device 5
Is fixed to the escalator. At that time, the spring 11e is in a state of being stretched between the press contact portion 11d and the frame 12.

On the other hand, as shown in FIG.
When removing or moving the
The operation knob 11b of the push spring body 11 is rotated so that the protrusion 11a is aligned with the position of the slot 12b. At this time, the push spring body 11 is pushed back by the elasticity of the spring 11e. After that, the operation knob 11b is rotated so that the protrusion 11
Hook a on the outer surface of the frame 12. This allows
The pressure contact portion 11d of the push spring body 11 can be held apart from the vertical surface 3a of the guide rail 3, and for example, when moving the place where the work is performed, the device 5 can be moved accordingly. Also, when the work is finished,
In this state, the device can be removed from the escalator and transported.

Since the present device 5 has the above-mentioned configuration, FIG.
By mounting the device 5 on the escalator as shown in FIG. 3, direct sunlight does not fall on the work place and the work place is not exposed to rainfall.

Second Embodiment FIG. 7 is a side view showing the construction of a work roof device for an outdoor escalator according to a second embodiment of the present invention. The same components as those of the conventional escalator and the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.
