Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balustrade of a passenger conveyor such as an escalator and an electric road, and more particularly to a balustrade of a portion visible to a passenger of a passenger conveyor.

[0002]

2. Description of the Related Art The railing of a conventional passenger conveyor is disclosed in
As described in Japanese Patent Application Publication No. 3-95690, in order to ensure the safety of the user and improve the design, for example, a screw end at the seam between the inner deck and the skirt guard contacting the inner deck is molded. It is mounted and concealed, and many of the moldings are made of the same material as other balustrades, such as aluminum.

[0003]

However, the molding on the railing of the conventional passenger conveyor described above is often used in old escalators, and when exchanging moldings that have been damaged over time with new parts, the die that has already been reduced is used. And the bending mold must be remanufactured. Also, when attaching a new molding to the balustrade of the escalator, the molding mounting surface of the balustrade is distorted due to aging, so molding with metal such as aluminum can not follow the mounting surface well, making the installation work quite difficult. turn into.

[0004] It is an object of the present invention to provide a railing for a passenger conveyor that facilitates the mounting work even on a molding mounting surface that has undergone plastic deformation due to aging.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention supports a handrail which is connected endlessly and synchronously moves with a plurality of steps which circulate and moves and fixes a fixed part thereof. In the parapet of the passenger conveyor covered by the above, the molding is made of resin.

In the balustrade of the passenger conveyor according to the present invention, since the molding for covering the fixing part of the balustrade is made of resin, it can follow the deformed mounting surface by utilizing its followability, thereby facilitating the mounting operation. be able to.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a balustrade when applied to an escalator as a balustrade of a passenger conveyor according to an embodiment of the present invention, and FIG. 2 is a front view showing a part of the balustrade with the balustrade omitted. An endlessly connected and circulating step 1 is disposed between a pair of upper and lower floors 3 and has an endless handrail 2 that moves in the same direction on both sides of the step 1. . A handrail frame 4 movably supporting the handrail 2 is fixed to an upper part of a balustrade panel 5, and a lower part of the balustrade panel 5 is a beam 7.
Is fixed to the deck 12 which is supported. The handrail frame 4 and the balustrade panel 5 are fixed to each other by a resin upper molding 8 attached with screws 10.
The butt guard between the skirt guard 6 and the balustrade panel 5 supported by the beam 7 and the balustrade panel 5 are covered with a resin lower molding 9 attached with screws 10, thereby improving the design of the balustrade body and improving the design of the balustrade body as described later. It prevents users from getting caught on clothes due to the appearance of balustrade parts.
These moldings 8 and 9 are arranged above and below the balustrade panel 5 in the portion shown in FIG. 1, and are arranged so as to wrap around the curved portion of the balustrade panel 5 in the terminal portion shown in FIG.

These moldings 8 and 9 are replaced with new parts when the damage becomes severe due to aging. However, if a new aluminum molding as in the past is to be mounted on the mounting surface of a balustrade that has been warped over time, the mounting will be distorted. It is difficult to follow the surface, and even if it can be mounted, there is a risk that a new aluminum molding will protrude toward the step 1 due to the distorted mounting surface, and this protruding portion will impair passenger safety. However, by manufacturing the new moldings 8 and 9 from resin, the flexibility of the material itself makes it possible to follow the mounting surface of the distorted balustrade, thereby facilitating the mounting, and preventing the protrusion to the step 1 side. Passenger safety can be improved. Further, in the escalator, there is a work of removing the molding 9 at the time of the maintenance work. However, by making the moldings 8 and 9 made of resin, the weight can be reduced, and the maintenance work at the time of carrying in and out of the moldings 8 and 9 is improved. You can also.

On the other hand, as shown in FIG. 1, the thickness of the molding 9, that is, the protrusion A toward the step 1, is larger than the gap B1 between the skirt guard 6 and the step 1, so that the clothes of the user can be worn. Since the skirt guard 6 is kept away from the skirt guard 6, the skirt guard 6 can be prevented from being caught by the gap B1. In addition, since such a pair of moldings 8 and 9 are provided above and below the balustrade panel 5, as shown in FIG. 2, the user is kept away from the gap B2 formed between the plurality of balustrade panels 5, and similarly. Thus, the user's clothes can be prevented from being caught by the gap B2. In addition, the moldings 8 and 9 are made of a colorable resin, and are colored with a color different from the balustrade panel 5 and the skirt guard 6, for example, yellow or red, so that access to the balustrade is dangerous. Be alerted.

Incidentally, since the moldings 8 and 9 are formed by connecting a plurality of moldings in the longitudinal direction, warping or gaps at the ends of the butted portions between the moldings 8 and 9 may cause an accident for the user. Conceivable. This measure will be described with reference to FIGS.

FIG. 3 is an enlarged cross-sectional view of the mounting portion of the molding 9 along the line YY in FIG. 2, and FIG. 4 is a partially simplified cross-sectional view of the balustrade before mounting the molding 9 of FIG. FIG. 5 is a partially simplified balustrade sectional view after the molding 9 is attached. First, as shown in FIG. 3, the molding 9 is formed in a wedge shape so that one end covers the other end, and is overlapped. The gap is D, and the gap at the opposite portion of the portion located on the back side is F
It has become. When mounting the molding 9, the gaps D and F of the facing portions shown in FIG. 3 exist between the adjacent moldings 9, so that the longitudinal position of the molding 9 can be adjusted within that range. Since the molding 9 is made of resin, it is conceivable that the molding 9 may be damaged by tightening the screw 10. However, a cylindrical distant piece 11 that matches the inside of a through hole formed in the molding 9 is arranged, and the distant piece 11 is removed. Since the screw 10 is screwed to the skirt guard 6 through the skirt guard 6, the tightening torque of the screw 10 is received by the distant piece 11 so as to withstand repeated tightening of the screw 10.

Molding 9 before installation on balustrade
Is bent toward the balustrade side at an angle C as shown in FIG. 4, but when the molding 9 is mounted on the balustrade, it follows a substantially flat mounting surface with its flexibility, and is shown in FIG. To be mounted. The end of the molding 9 tries to return in the direction of the arrow shown in FIG. 5 by elastic force. However, since the end of the molding 9 can be prevented from warping to the step 1 side opposite to the skirt guard 6, the end of the molding 9 can be used. It is possible to prevent the customer's clothes and feet from being caught. Here, the angle C shown in FIG. 4 is desirably large enough not to damage the molding 9 due to the residual stress due to the bending angle C when the molding 9 is attached, and the end of the molding 9 has a wedge shape. Therefore, the depth E of the facing portion gap D generated at the time of the mounting adjustment can be reduced, and the molding 9 itself can be prevented from being caught by the gap of the depth dimension E.

Although the above embodiment has been described with reference to an escalator, the present invention can be similarly applied to a railing of another passenger conveyor having a structure other than the railing shown in FIG.

[0014]

As described above, the balustrade of the passenger conveyor according to the present invention has a molding made of resin.
Even if the molding mounting surface has undergone plastic deformation due to aging, it can be mounted to conform to the mounting surface due to its flexibility, facilitating the mounting work, and eliminating the warping of the molding to the step side to passengers. Safety can be improved.
