Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the railings of passenger conveyors such as escalators or moving walkways, and particularly relates to improvements in the mounting structure of inner decks on both sides of steps.

[Prior art]

Generally, an escalator has handrails 2 on both sides of steps 1 on which passengers ride, as shown in Figure 1.
The skirt guard panels 3 are placed on both sides of the steps 1 with a small gap between them to prevent passengers' feet from getting caught.
It consists of a balustrade panel 5 disposed above this via an inner deck 4, and a handrail 7 etc. disposed on the outer peripheral edge of this balustrade panel 5 via a guide rail 6. The inner deck 4 is constructed by connecting inner deck unit members 4' divided into predetermined lengths in the longitudinal direction of the escalator.

As shown in FIG. 2, the skirt guard panel 3 of the parapet 2 is usually attached to a panel support 8 with an L-shaped cross section whose upper end is fixed to a truss (not shown) in the longitudinal direction. is attached so as to be covered and hidden by the lower end of the inner deck 4 shown in FIG.

Here, the conventional fixing structure of the skirt guard panel 3 and the inner deck 4 that covers it to the panel support 8 will be described with reference to FIG. The upper ends of the panels 3 are overlapped, a screw hole is cut, and the screws 9 are used to fix them.The lower end of the deck 4 is overlapped to cover the surface side of the panel 3, and the above-mentioned skirt is aligned with the screw hole 10 formed in advance in the deck 4. Standing plate part 8 of guard panel 3 and panel support 8
Forming screw holes 11 and 12 integrally with a,
It was removably fixed with screws 13.

However, with the above-mentioned fixing structure, if the deck 4 and skirt guard panel 3 are once removed for maintenance or inspection, the skirt guard panel 3 is first fixed to the panel support 8 when reassembling, and then the deck 4 is In order to stop the above-mentioned skirt guard panel 3 and panel support 8,
The screw holes 11 and 12 of the deck 4 often do not match and are misaligned.
The screw 13 could not be inserted properly from the 0 position, and the screw hole 10 of the skirt guard panel 3 had to be drilled out and made into a blank hole, which required very troublesome work.

For this reason, recently, as shown in FIGS. 4, 5, and 6, the upper end 3a of the skirt guard panel 3 is
The rising plate part 8a of the panel support 8 with an L-shaped cross section
It is fixed with screws 9 lower than the upper end, and on the other hand, at the upper end of the rising plate part 8a of the panel support 8, there is an inverted U-shaped cross section made of a metal plate, synthetic resin, gourd, etc. with the same thickness as the skirt guard panel 3. Spacer 1
6 are continuously or partially sandwiched in the longitudinal direction, then the decks 4 are overlapped so as to cover the spacer 16 and the skirt guard panel 3, and the screws 13 passed through the screw holes 10 are inserted into the skirt guard panel 3. The rising plate portion 8 of the panel support 8 is inserted through the gap 15 between the upper end 3a and the lower end of the spacer 16.
A structure has been proposed in which the screw is screwed into a screw hole 12 formed in a.

[Problem that the invention attempts to solve]

However, with this structure, the number of parts increases compared to the conventional one, which not only makes parts management troublesome, but also requires the trouble of installing the spacer 16 during assembly on site, which has the disadvantage of significantly increasing the number of work hours on site. be.

The present invention has been developed in view of the above points, and aims to provide a railing for a passenger conveyor that allows the inner deck to be easily attached without increasing the number of parts and requires less man-hours for assembly work on site.

[Means for solving problems]

The present invention includes a two-pronged clip that supports the balustrade panel side on the back side of the inner deck unit member that covers the upper end of the skirt guard panel and the screw fixing part, and also creates a gap with respect to the upper end of the skirt guard panel. A bending member having a plate thickness substantially equal to that of the skirt guard panel extending downwardly and facing away from each other is provided so as to protrude beyond one longitudinal end of the back surface of the inner deck unit member, and the lower end of this bending member and A screw is passed through the gap between the skirt guard panel and the upper end, so that the inner deck unit member can be removably attached to the panel support.

[Effect]

With the configuration as described above, not only can the bending member serve as a conventional spacer, but also the joints between the inner deck unit members can be easily aligned.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 7 is a sectional view showing an example of the inner deck mounting structure according to the present invention, and FIG. 8 is a perspective view of FIG. 7.
In the figure, reference numeral 19a denotes a bent member with a width of about 50 mm and approximately the same thickness as the skirt guard panel 3, and is bonded to the back surface of the inner deck unit member 4'. Reference numeral 19b denotes a thin plate bending member joined to the back surface of this bending member 19a by spot welding, and the bending member 19a and the thin plate bending member 19b form the bracket 18 of the support body 17.
A two-pronged clip 19 is configured to engage with. The end of the clip 19 on the side of the skirt guard panel 3 extends vertically downward, covers a part of the upper end of the rising plate part 8a of the panel support 8, and faces the upper end of the skirt guard panel 3 with a gap 15 in between. will be placed in Therefore, the inner deck unit member 4' connects the screw 13 passed through the screw hole 10 to the upper end 3a of the skirt guard panel 3 and the clip 19.
It is removably fixed without a spacer by penetrating the gap 15 between the lower end of the panel support 8 and screwing it into a screw hole 12 formed in the rising plate portion 8a of the panel support 8. Also, this clip 19 is, for example, the eighth clip.
As shown in the figure, if the inner deck unit member 4' is attached so that it slightly protrudes from one or both ends in the longitudinal direction, the joints between the inner deck unit members can be easily aligned, and the inner deck 4 with a good design can be achieved. Can be configured.

[Effect of idea]

With a balustrade of this type, one of the clips conventionally used for support on the balustrade panel side is used instead of a spacer that prevents the inner deck from falling toward the balustrade panel side when the lower end is attached. Since parts can be used, the number of parts does not increase more than necessary, and the number of man-hours on site does not increase. Furthermore, by variously devising the attachment positions of these clips, it is possible to obtain a railing for a passenger conveyor in which the joints of the inner deck unit members can be extremely easily aligned with each other.
