For example, the load of the curing device 6 may be received by the floor surface or the stairs 22 and the curing device 6 may be supported by a component of the escalator 1 such as the frame 2 to prevent the curing device 6 from falling.

Further, as shown in the first embodiment, when the escalator 1 is installed on the stairs of the railway station, the frame 2 of the escalator 1 is used as a first operation.
A preparatory operation for installing the escalator 1 is performed, and after the first operation, a second operation of installing the frame 2 is performed. Perform a third task,
After the above operation, a fourth operation of assembling the escalator 1 may be performed, and after the fourth operation, a fifth operation of removing the curing tool 6 and mounting the exterior parts of the escalator 1 may be performed.

Next, a second embodiment of the present invention will be described with reference to FIGS. Also in the second embodiment, the escalator 1 in which the passenger conveyor to be cured is arranged side by side on the stairs 22 disposed between the upper floor 20 and the lower floor 21 of the building, similarly to the first embodiment described above. The escalator 1 includes a curing device 30 that covers the entire area on one side.

The curing tool 30 includes a frame 31 and a rigid plate-like body, ie, a panel 32, mounted on the frame 31, and the panel 32 is attached to the ceiling 2 of the building.
It has a configuration having an extension portion 39 extending to around 3.

As shown in FIG. 5, the frame 31 has overhang portions 33 and 34, and these overhang portions 3 and 34 are provided.
3, 34, and holes 35, 3
The frame 2 is provided with holes formed in the frame 2 so as to fit the bolts 6, and bolts 37 and 38 inserted into the corresponding holes.

The overhanging portions 33, 34 of the frame 31 described above,
The holes 35 and 36 and the bolts 37 and 38 are
Means for holding the escalator 1 itself, that is, the curing tool 6 is used to hold the frame 2 forming the main body of the escalator 1
To form a fixing means.

In the second embodiment constructed as described above, the escalator 1 can be cured without the need for legs standing on the upper floor 20, the lower floor 21, and the stairs 22. Thus, the same operation and effect as those in the first embodiment can be obtained. In particular, in the second embodiment, the escalator 1 is covered with the extended portion 39 of the curing device 30 over a wide area up to the vicinity of the ceiling 23 of the building. The surrounding environment can be more reliably protected. Therefore, a pedestrian or the like who walks on the stairs 22 can be more reliably protected.

FIG. 6 is a sectional view showing a main part of a third embodiment of the present invention. In the third embodiment, the frame body 31 includes the overhang portion 33 and the hook-shaped locking portion 41. The overhang portion 33 is provided with a hole 35, and a hole corresponding to the hole 35 is provided at a corresponding position of the frame 2.
A bolt 37 is inserted into the hole 35 or the like. Further, the frame 2 is provided with a hook-shaped locking portion 40 to be engaged with the locking portion 41 described above. Other configurations are the same as those of the second
For example, it is equivalent to the embodiment.

The above-described locking portion 41 of the frame 31 and the locking portion 40 of the frame 2 are holding means for holding the curing tool 30 on the escalator 1 itself, that is, the engaging means for fixing the curing tool 30 to the frame 2. Means.

In the third embodiment, when attaching the curing tool 30 to the escalator 1, first, the locking portion 41 of the frame 31 is engaged with the locking portion 40 of the frame 2, and then the frame The holes 35 of the projecting portion 33 of the body 31 are adapted to the holes formed in the frame 2, and bolts 37 are inserted into these holes 35 and fastened.

In the third embodiment configured as described above, similarly to the second embodiment, the upper floor 20, the lower floor 21,
In addition, the escalator 1 can be cured without the need for a leg standing on the stairs 22, and the same operation and effect as those in the above-described second embodiment can be obtained. In particular, in the third embodiment, since the locking portion 41 of the frame body 31 is engaged with the locking portion 40 of the frame 2 by manual operation, for example, the fastening by the bolt 37 is performed. Can be reduced, and the work of attaching the curing tool 30 can be performed efficiently.

In the third embodiment, the overhanging portion 33 is provided and the overhanging portion 33 is fastened to the frame 2 via the bolt 37. However, instead of providing the overhanging portion 33, the same as the locking portion 41 is used. It is also possible to provide a locking portion and provide the frame 2 with a locking portion to which the locking portion is engaged.

In each of the above embodiments, the curing tools 6 and 30 are provided so as to cover the entire area on one side of the escalator 1, but the present invention provides the curing tools 6 and 30 as described above. It is not limited to. For example, the escalator 1 may be provided so as to cover only a part of one half or the like of one side, or may be provided so as to cover the entire area of both sides of the escalator 1. May be provided to cover the upper and lower entrances.

In each of the above embodiments, the escalator 1 has been described as an example of the passenger conveyor to be cured. However, the escalator 1 may be an ordinary escalator, or a thin escalator which has been developed recently. An escalator, that is, an escalator whose total height is lower than that of a normal escalator by, for example, 20 to 30% may be used. Further, instead of such an escalator 1, it may be applied to a moving sidewalk.

[0029]

As described above, according to the present invention,
Curing of the passenger conveyor can be carried out without the need for a leg standing on the floor on which the passenger conveyor is installed, the number of members can be reduced as compared with the related art, and the structure can be reduced. It can be simplified, and the production cost can be reduced. In addition, the overall shape can be reduced as compared with the conventional one by the absence of the legs, and handling during transportation, management, and the like can be easily performed. Furthermore, the space around the passenger conveyor can be made wider than before, and the restrictions on the traffic area and the like can be relaxed.
