TECHNICAL FIELD OF THE INVENTION
The present invention relates to a passenger conveyor, in particular, relates to a passenger conveyor such as stairs on the mounting to Rue Sukareta or moving walkway is a walkway.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a passage facility in which a passenger conveyor is installed adjacent to or placed on a stairway which is a pedestrian passage of a building structure has been disclosed in JP-A-7-189449 and JP-A-59-190179. Have been.
[0003]
[Problems to be solved by the invention]
The former of the prior art described above is based on an arrangement with a passenger conveyor adjacent to the floor, or on the upper part of the stairs, on the condition that the stairs near the top of the stairs are deleted (with a partial removal operation). There is disclosed a configuration in which it is installed in a mounted form. And this example is basically about the installation configuration of handrails for stairs, and the range of incidental work (deletion of stairs) accompanying the installation of the passenger conveyor is reduced, resulting in shortening installation work period and minimizing cost. There was no consideration for planning. Also, no consideration is given to reducing the strength of the entire original stairs due to the deletion of the stairs.
[0004]
On the other hand, the latter of the prior art is a configuration in which a separate stair is added to the former example, and has a configuration in which the degree of obstacles is further increased in terms of ancillary work.
[0005]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a passenger conveyor and a passage device having a configuration in which when a passenger conveyor is placed on a staircase, an incidental work area for installing the passenger conveyor can be minimized and stair strength can be maintained.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention forms a step along the nose of the stairs at the bottom of the end of the upper machine room of the frame of the passenger conveyor. Also, a buried portion is provided at the top of the stairs so that the upper surface of the upper machine room and the passage on the stairs are flush with each other.
[0007]
According to the above configuration, when placing the passenger conveyor on the stairs, it is not necessary to delete the vicinity of the top of the stairs, which can contribute to shortening the construction period and reducing costs by reducing the range of the auxiliary work. Further, by eliminating the need for the deletion, the strength of the original stairs is not reduced, and the predetermined facility capacity can be maintained.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0009]
The passage equipment shown here shows a form in which an escalator 2 which is a kind of a passenger conveyor is placed on an existing stair 1. The stairs 1 form a walking path by connecting the lower floor 3 to the upper floor 4, and show a stair 1 having an upper stair 1A, a lower stair 1B, and an intermediate landing 1C.
[0010]
The escalator 2 is provided with a frame 2F installed from the lower floor 3 to the upper floor 4, and a lower machine room with a top covered with the floors 2B and 2C at the upper and lower portions of the frame 2F. 2D and an upper machine room 2E. In the frame 2F, a plurality of steps 2A that are connected endlessly and circulate and move are guided and supported.
[0011]
Here, a step 2EEE is formed on the bottom surface of the terminal end 2EE of the upper machine room 2E of the escalator 2 along the stair 1AA of the upper stair 1A. In order to avoid interference (contact) between the step 2EEE and the stair 1AA. In addition, the support beam 2H of the frame 2F is supported by the strength member at the top of the stairs 1E.
[0012]
On the other hand, as shown in FIG. 2, the escalator 2 has a balustrade standing on both sides thereof along the moving direction of the step 2A, and guides an endless handrail 2G synchronously moving with the step 2A to the periphery of the balustrade. ing. In the upper machine room 2E, there are provided a large gear 2S for driving the step 2A and the endless handrail 2G, a drive unit 2I, a drive chain 2J, a control box 2K, and the like.
[0013]
Dimensionally, the thickness h of the machine chamber in which the stepped portion 2EEE is formed is reduced to about half (h ≒ H / 2) with respect to the thickness H of the upper machine chamber 2E. A small device such as a box 2K is arranged and stored.
[0014]
Further, an embedding portion 1D made of asphalt or the like is provided in a recess formed between the terminal end portion 2EE of the upper machine room 2E and the upper floor 4 (having a depth of one step to several steps in some cases), The floor 2C of the upper machine room 2E and the passage of the upper floor 4 are finished to be flush.
[0015]
With the above configuration, the step of removing the stairs for installing the escalator 2 is not required, and the harmful concave portions for pedestrians are eliminated by a simple measure. The illustrated escalator 2 can have the same configuration as described above even in the case of an inclined moving sidewalk.
[0016]
【The invention's effect】
As described above, according to the present invention, when a passenger conveyor is placed on a staircase, it is possible to provide a passage facility having a configuration capable of minimizing an incidental work area and maintaining required strength.
