Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor, and more particularly to a passenger conveyor with an improved balustrade panel attachment mechanism.

[Background of the invention]

The passenger conveyor is provided with balustrades on both sides of rotating steps arranged in an endless manner, and the balustrades have balustrade panels. The balustrade panel is attached to the frame, but due to dimensional errors in the frame and the balustrade panel, it is troublesome to adjust the attached position during assembly, resulting in poor installation workability.

The drawbacks of such conventional passenger conveyors will be specifically explained with reference to FIGS. 1 to 4. Balustrades 2 are provided on both sides of the step 1 which is arranged in an endless manner and rotates. The balustrade 2 includes a handrail frame 4 which is reinforced and supported by the balustrade pillars 3, a handrail 5 which is guided by the handrail frame 4 and rotates synchronously with the step 1, and an upper end of which is connected to the handrail frame. The parapet panel 10 is sandwiched between the inner edge of the molding 4 and the upper panel beam 6, the lower end thereof is located on the skirt guard beam 7, and the balustrade panel 10 is sandwiched between the inner molding 8 and the lower panel beam 9. As shown in an enlarged view in FIG.
This structure is such that the upper end of the handrail panel 10 with the letter-shaped packing 11 attached thereto is inserted into the gap formed between the handrail frame 4 and the upper panel beam 6.
As shown in an enlarged view in FIG.
A lower panel beam 9 is fixed on the top and has a packing 13 with an inverted U-shaped cross section attached to the part bent to be parallel to the slope of the parapet panel 10, and an inner molding with a molded rubber 14 attached to the tip. 8, and the lower end of the parapet panel 10 is placed on the head of an adjustment jack bolt 15 screwed into the skirt guard beam 7.
In such a balustrade 2, there are manufacturing dimensional errors in the balustrade panel 10 and assembly errors in the balustrade frame, so the position of the balustrade panel 10 in the height direction must be adjusted by turning the jack bolts 15. Moreover, if there is an error such that the groove width between the handrail frame 4 and the upper panel beam 6 that receives the packing 11 attached to the upper end of the parapet panel 10 becomes narrow,
The corners of the handrail frame 4 and the upper panel beam 6 dig into the gasket 11, making it impossible to insert them smoothly and causing the parapet panel 10 to bend, making adjustment difficult.

In addition, since the packing 11 is configured to be in contact with the upper panel beam 6 at an angle as shown in FIG. 3, there is a problem that the supporting of the inclined panel lacks stability and the packing 11 is damaged more quickly. Furthermore, as shown in FIG. 4, the lower panel beam 9
The balustrade panels could not be stably supported without bending the vertical sides of the railings, resulting in a complex support structure.

[Purpose of the invention]

The present invention addresses the above-mentioned problems, and aims to eliminate the need for adjusting the mounting position of the balustrade panels, and to simplify the support structure of the balustrade panels arranged at an angle. The purpose of the present invention is to provide a passenger conveyor that can provide stable support.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention forms a gasket with a substantially inverted U-shaped cross section by providing a groove deeper than the insertion depth of the balustrade panel, and the surface of one leg of the inverted U-shape is formed in the groove. An inclined surface inclined at the same angle as the inclination of the parapet panel in the depth direction,
A recess opening laterally is formed on the surface of the other leg end of the inverted U-shape, and the upper end of the balustrade panel is inserted into the groove with the inclined surface of this gasket in contact with the downward vertical side of the upper panel beam. and engage the edge of the handrail frame in the recess to form an upper gasket, and with the groove of the gasket fitted into the upward vertical side of the lower panel beam of the same thickness as the balustrade panel. The back surface of the balustrade panel was brought into contact with the inclined surface to form a lower seal, and the lower end of the balustrade panel was placed on a fixing member.

[Embodiments of the invention]

One embodiment of the present invention will be described in detail below with reference to FIGS. 5 and 6, but illustrations and explanations of the same conventional components will be omitted.

FIG. 5 shows an edge holding part at the upper end of the balustrade panel 10, and an upper gasket 16 into which the balustrade panel 10 is inserted.
has a substantially inverted U shape with a groove 16b into which the upper edge of the balustrade panel 10 is slidably fitted;
A concave portion 16a that sandwiches the edge of the handrail frame 4 is opened laterally on the surface of one leg end of the letter shape.
The surface of the other leg of the inverted U-shape has an inclined surface that is inclined at the same angle as the parapet panel 10 with respect to the depth direction of the groove 16b, and a downward facing surface provided on the upper panel beam 6 is formed on this inclined surface. Make sure the vertical sides are in close contact. The bottom surface of the inverted U-shape forms an upper surface that comes into contact with the horizontal inner surface of the handrail frame 4. When the upper gasket 16 is fitted between the edge of the handrail frame 4 and the upper panel beam 6 and the inclined surface is brought into contact with the vertical side of the upper panel beam 6, the groove 16b is formed in the balustrade panel 10. The installation angle is the same as the mounting angle. The groove 16b is connected to the balustrade panel 10.
It is made deeper than the amount that the balustrade panel fits in so that there will be a space behind it when it is installed.

FIG. 6 shows the lower edge holding portion of the balustrade panel 10, and the lower packing 18 used here has the same shape as the upper packing 16. Here, the lower edge of the balustrade panel 10 is placed in contact with the upper surface of the skirt guard beam 7, and its outer surface is attached to the lower panel beam 17 attached to the skirt guard beam 7.
The back side is closely attached to the inclined surface of the lower packing 18 attached to the upward vertical side of the inner molding 8, and the front side is pressed by the mold rubber 14 attached to the tip of the inner molding 8.

That is, instead of fitting the balustrade panel 10 into the groove 18a of the lower packing 18, by fitting it to the upward vertical side of the lower panel beam 17, the groove 18
a will be vertical, and instead the slope will match the slope of said balustrade panel 10. At this time, the inverted U
Since the recesses provided in the letter-shaped legs are located on the opposite side of the balustrade panel 10, the recesses do not interfere with the installation of the balustrade panel. Further, the thickness of the vertical side of the lower panel beam 17 needs to be the same as that of the balustrade panel 10 inserted into the groove 18a.

As described above, according to the balustrade panel clamping part, there are manufacturing dimension errors of the balustrade panel 10 and assembly errors of the balustrade frame body, and when the balustrade panel 10 is installed, the upper edge position dimension and the upper gasket 16 position dimension may be slightly different. Even if there is a shift, the amount of shift is absorbed by a change in the amount of fitting of the parapet panel 10 into the groove 16b of the upper packing 16. Therefore, there is no need to adjust the mounting position of the parapet panel 10 in the height direction, and no jack bolts are required for adjustment. Further, in this embodiment, the lower panel beam 17 is made of general angle steel (L
Using material (steel), install the parapet panel 1 with the lower packing 18.
Since the inclined surfaces that sandwich the 0 are formed, there is no need to bend the lower panel beam 17, and manufacturing is easy. Furthermore, the upper gasket 16 is stably fitted by coming into contact with the horizontal inner surface of the handrail frame 4 and the vertical surface of the upper panel beam 6, and the lower edge of the handrail panel 10 is directly received by the skirt guard beam 7. This has the advantage that the balustrade panel 10 can be held stably. Furthermore, upper patch 16 and lower patch 1
8 have the same shape, there is no need to prepare two gaskets of different shapes, and there is no need to select a gasket during assembly, which simplifies the work.

〔Effect of the invention〕

As explained above, the present invention has a substantially inverted U-shape having a groove deeper than the insertion depth of the balustrade panel, and the balustrade panel has a surface of one leg of the inverted U-shape in the depth direction of the groove. The handrail frame has an inclined surface inclined at the same angle as the inclination of the handrail frame, and a gasket is formed on the other end surface of the inverted U-shaped leg so as to have a concave opening laterally for engaging the edge of the handrail frame. Since the upper and lower ends of the balustrade panel are fixed through the packing, the groove can freely absorb changes in the amount of insertion of the balustrade panel due to dimensional errors when installing the slanted balustrade panel. As a result, it is possible to eliminate the need for adjusting the mounting position of the parapet panel.

Furthermore, by using this packing, the inclined balustrade panel can be supported without processing other supporting members, so the supporting structure can be simplified.

Furthermore, since the shapes of the pads used on the top and bottom of the balustrade panel are the same, there is no inconvenience of having to use two different pads, and the balustrade panel is held using the sloped surface of the pad. Stable support can be provided.
