Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balustrade structure of a passenger conveyor, and more particularly to a balustrade structure of a passenger conveyor suitable for an escalator and an electric road.

[0002]

2. Description of the Related Art In passenger conveyors such as escalators, in addition to the transport function, design and safety, particularly, recently, light weight and high efficiency of assembly are strongly required.

[0003] In particular, the light weight and high efficiency of assembly are such that the strength burden on the building side where the passenger conveyor is to be installed is light,
It is pointed out that the obstacles to the progress of building construction work can be reduced. In recent years, the demand for short construction periods on the building side has been increasing.

[0004] By the way, generally known passenger conveyors are designed such that a step and a moving handrail travel endlessly back and forth between one step and the other step. The balustrade stands upright and guides and supports the outward path of the moving handrail. The balustrade comprises a balustrade panel, an inner deck cover, an outer deck cover, a skirt guard and the like, and constitutes a design part of the entire passenger conveyor.

[0005] Here, the balustrade components are the same as those disclosed in
As is known from Japanese Patent Publication No. 114281, there is a support as a main member for supporting the lower end portion of the balustrade panel. This support supports the balustrade panel with a crimping plate and a crimping bolt, while the outer deck supports the outer deck cover. And is ultimately mounted under the floor of the building and is fixed with bolts to the upper frame of the main body frame that holds the strength of the entire passenger conveyor. In addition, the moving handrail on the return path is guided and supported by a guide and a support for supporting the same, and travels endlessly.

In the above structure, since the balustrade panel, the skirt guard and the guide portion of the moving handrail are individually held in strength by using the main body frame as a base, the weight due to the use of the long support is reduced. It is necessary to increase the number of parts such as an increase in the number of supports and the like.

In order to solve these problems, Japanese Patent Laid-Open No. 62-249886 discloses that at least a balustrade panel, an inner deck cover, and an outer deck cover are attached to a main body frame to support a moving handrail. Assuming that the balustrade is composed, a balustrade panel, an inner deck cover, a support consisting of an integrally molded member that holds each of the outer deck cover in common, and a return side moving handrail guide mounting part is provided on the lower side of the support I have.

[0008]

The prior art described above does not take into account the speed of the assembling work and the assembling accuracy. In particular, when assembling the assembling accuracy, the backward moving hand at the lower side of the support is not suitable. In the rail guide mounting portion, since it is fixed by using the mounting hole, it is difficult to maintain the assembly accuracy of the moving rail guide, and there has been a concern about the premature wear of the moving rail guide material.

SUMMARY OF THE INVENTION An object of the present invention is to simplify the structure of the balustrade panel, particularly the lower part of the balustrade among the balustrades of the passenger conveyor, and to improve the assembling accuracy and assembling efficiency.

[0010]

In order to solve the above-mentioned object, at least a balustrade panel, an inner deck cover, and an outer deck cover are attached to a main body frame to constitute a balustrade for supporting a moving handrail. A panel and an inner deck cover, a support made of an integrally formed member that holds each of the outer deck cover in common, and a support provided with a return-side moving handrail guide attaching portion at a lower side of the support; The lower edge of the support is formed as a convex portion, and the convex portion at the lower edge of the support is provided in at least one place and is continuously or intermittently arranged in the longitudinal direction.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a passenger conveyor, and FIG. 2 is a sectional view taken along the line ZZ of FIG. 1 showing an embodiment of the present invention.
FIG. 3 is an enlarged view of a portion A in FIG. 2, and FIG. 4 shows an embodiment of the present invention. 5 and 6 show one embodiment of the present invention.

A general passenger conveyor generally includes a step 1 and a moving handrail 2 with one entrance 3 and the other entrance (not shown).
It is designed to travel endlessly between and
A balustrade 4 stands upright on both sides of the step 1 to guide and support the outward path of the moving handrail 2. The balustrade 4 includes a balustrade panel 5, an inner deck cover 6, an outer deck cover 7, a skirt guard 8, and the like, and constitutes a design portion of the entire passenger conveyor.

The balustrade according to one embodiment of the present invention comprises a lower end 5a of a balustrade panel 5 arranged at the lower side of the balustrade 4.
And a packing 12 covering the inner deck cover 6, an inner deck cover 6, and an outer deck cover 7. The support 12 is formed of an integrally molded member such as aluminum, and the inner deck cover is provided on the support 12. Base 13 for assembling 6
Deck support 12a for supporting the balustrade, balustrade support 12b for supporting the balustrade panel, outer deck cover support 12c for supporting the outer deck cover 7, and moving rail guide support for supporting the guide 14 of the moving rail 2 on the return path side. A part 12d is provided.

Here, the structure of the movable handrail guide support portion 12d which supports the guide 14 of the backward handrail 2 provided on the lower side of the support 12 has a structure in which the end of the movable handrail guide support portion has a width W. And a convex portion having a height H. In addition, the guide mounting portion is provided with an opening w so that the mounting bolt head 15 can be inserted in order to fix the support 16 of the guide 14.

Further, as another example, both ends of the moving handrail guide supporting portion are formed of convex portions having a width W and a height H, and a width w1 between the both ends of the moving handrail guide supporting portion is formed. Guide 14
The width w2 of the support member 16 is the width w1 between the convex portions at both ends of the guide support portion.
The configuration is almost the same as

According to the invention described above, with respect to the mounting of the guide 14 of the moving handrail 2 on the return path, when the guide support 16 is mounted on the moving handrail guide support portion 12d, the guide support end 16a is connected to the guide support end 16a. By fixing the end of the moving handrail guide supporting portion to the convex portion having the width W and the height H, the assembling accuracy of the guide 14 for the moving handrail on the return path is improved.

[0017]

According to the present invention, since the assembling operation can be easily and accurately guided, the assembling operation can be performed in a shorter time than the conventional assembling operation time. It is possible to provide a passenger conveyor with improved assembling accuracy at a low operating cost.
