Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for installing a passenger conveyor for installing an escalator and a moving walkway which is arranged on an existing staircase provided in a building.

[0002]

2. Description of the Related Art As a conventional method of installing a passenger conveyor arranged on an existing staircase provided in a building, there is a method disclosed in Japanese Patent Application Laid-Open No. 55-190479, for example. That is, the truss constituting the main frame is shallow, the upper truss is placed on the upper floor, the lower truss is placed on the lower floor, and the middle truss is placed on the existing stairs.

[0003]

In the above-described conventional method of installing a passenger conveyor, the upper truss and the lower truss need to be formed very shallowly. Therefore, there are the following problems. That is, there is a step between the floor of the passenger conveyor and the floor above and below the building, so that stairs and slopes are required at this location. In addition, the railing of the passenger conveyor protrudes greatly from the end of the existing stairs in the longitudinal direction of the existing stairs, and is usually a passage,
The space on the lower floor may be smaller.

As another conventional method of installing a passenger conveyor, there is a method disclosed in Japanese Patent Application Laid-Open No. Sho 59-190179, for example. That is, the lower part of the truss constituting the main frame is placed without being embedded in the lower floor of the building. Also in this case, a step is formed between the entrance floor of the passenger conveyor and the lower floor of the building, so that a stair or a slope is required at this location. In addition, the lower balustrade of the passenger conveyor may protrude greatly from the end of the existing stairs in the longitudinal direction of the existing stairs, thereby obstructing the passage of the lower passage provided on the lower floor.

As another conventional method of installing a passenger conveyor, there is a method disclosed in Japanese Patent Application Laid-Open No. 7-179282, for example. That is, a support device that cuts out the landing portion of the existing stairs of the building and supports the passenger conveyor from the floor of the building is attached. In this case, it is necessary to cut out the middle part of the existing stairs.

As another conventional method of installing a passenger conveyor, there is a method disclosed in, for example, JP-A-7-179284 and JP-A-7-189449. That is, this is a method in which the upper part of the existing stairs of the building is cut out to install the passenger conveyor. When the passenger conveyor is installed in the existing stairs, it is necessary to cut out the vicinity of the upper part of the existing stairs.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and there is provided a passenger conveyor which can be easily installed and dismounted by a small amount of processing on the existing stairs of the building with little processing. The purpose is to obtain an installation method.
