Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly to an improvement in the structure of a handrail in a portion that guides a handrail.

[Prior art]

Generally, the structure of a passenger conveyor is as shown in Figs. 1 and 2. Steps 1 and handrails 2 are arranged in an endless manner and rotate, and a glass panel 3 is placed between them.
．． A parapet 6 consisting of a deck board 4 and a frame 5 is installed! are doing. The strength of all the components such as the handrail 6 is maintained by the main body frame 7 and mounted on the building floor F.

Here, if we describe the configuration of the parapet 6 in detail, we will explain the strong FK of this, 1
The rigidity of the frame 5 for guiding the handrail 2f is maintained by the glass panel 3, which is a support structure located below the deck board 4 and is fixed to the main body frame 7 and stands upright. At the upper end of the glass panel 3, a frame 5 is fitted to the glass panel 3 via a soft gasket 10, and a guide 11 made of nylon material with good sliding properties is attached to the upper end of the frame 5. Usually, they are fixed with screws 12 and arranged in a continuous manner so that they do not move.

Note that the use of such guides 11 made of nylon material is a very recent structure, and conventionally the running resistance of the handrail 2 is large. As is well known, the convex line portions U are guided by a rotating body in which guide rollers 9 are built into the frame 5. Here, in the conventional guidance system using a rotating body, there is a point in the aging life of the rotating body, and by removing this rotating body, the frame 5
The structure shown in Figure 2 began to be adopted with the design intention of emphasizing the transparent expanse of glass flannel (3).

However, as mentioned above, the recent parapet structure in which the inner circumference of the no-drail 2 is guided by sliding material is
Improved reliability and ([4]
Although much has been achieved with the modernization of Tezain, the following issues still remain and need to be resolved.

In other words, if the guide 11 is a sliding type in which the guide 11 is in constant contact (as shown in Fig. 2), it is inevitable that the guide 11 will be worn out once every few to ten years. There is peace of mind in replacing it with a new one, but there is a problem in that it is difficult to set a time estimate for this replacement. In particular, if the wear of this guide 11 is left unnoticed,
The engagement part I with Freno 5 (may wear out and fall off,
This is extremely inconvenient as the head of the screw 120 is exposed and may damage the inner periphery of the handrail 2.

[Purpose and outline of the invention]

SUMMARY OF THE INVENTION In view of this point, the present invention has been devised to provide a handrail structure that allows the wear state of the guide 11 to be visually observed.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 3, the balustrade structure other than that shown is the same as that in FIG. 2 and will not be described here, but the present invention is characterized in that grooves 13a and 13b are provided near both sides of the guy 1130. Here, the grooves 13a and 13b have a thickness t1 within which the guide 13 can be used even if it is worn out, that is, a retaining portion K with the frame 5, relative to the thickness t of the upper surface of the guide 13. The remaining 9% is a boundary line H of the limit plate thickness t, which does not allow any part to separate from the upper surface of the sliding part further down. The grooves 13a and 13b are formed in the guide 13.
It is provided along the entire length of the guide 13 in the longitudinal direction, and is usually molded at the same time as the guide 13 is molded.

By doing this, the upper surface of the guide 13 and the grooves 13a and 13b can be removed during daily maintenance and inspection of the passenger conveyor.
By visually observing the positional relationship with the guide 13, the amount of wear on the guide 13 can be confirmed, and problems such as falling off from the retaining portion as described above can be completely eliminated.

〔Effect of the invention〕

The present invention described above has the advantage of further improving the reliability of the guide section of the rail.

In the explanation of the first text, the wear of the guide is indicated by the grooves 13a and 13b, but the present invention is not limited to this, and there is no problem with the system shown in FIGS. 4 and 5.

FIG. 4 shows an example in which a hole-shaped recess g1 or a protrusion g is provided on the surface of the guide 080. In this method, as in FIG.
The state of wear can be confirmed by visually observing the positional relationship with the Furthermore, as shown in FIG. 5, a hole-shaped recess g3 is provided on the back surface of the guide G, and the guide
Colored part of the wear indication line in a color different from the color tone of g4'5
It is also possible to provide c. Further, if necessary, it is also possible to provide a groove g&y on the lower side of the guide Gt to display wear and check the wear condition on this lower side.
