Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balustrade device for a passenger conveyor, and more particularly to a balustrade device for a passenger conveyor which is suitable for repairing mounting screw holes of a skirt guard.

[0002]

2. Description of the Related Art Conventionally, a screw hole for mounting a skirt guard is broken, and a screw for mounting cannot be used because it cannot be screwed in, or the screw comes out and a passenger's foot comes into contact with the screw so that an injury is injured. There is a problem that
In Japanese Patent No. 130586, a plurality of mounting holes are formed in an upper beam for supporting a skirt guard, and a bracket having screw holes formed corresponding to the mounting holes is brought into contact with the anti-skirt guard side of the upper beam. Attach the skirt guard and bracket to the upper beam with a screw that passes through the upper beam and is screwed into the screw hole of the bracket, and use the screw that is screwed into the other screw hole of this bracket to attach the inner deck board located above the skirt guard. A parapet device for a passenger conveyor that has been installed has been proposed.

[0003]

SUMMARY OF THE INVENTION In the above prior art, when removing the inner deck board and the skirt guard, the bracket may be dropped unless the screw is removed while pressing the bracket, and the bracket is stored so as not to be lost when removed. There are things that must be done and screw holes may not match unless they are attached to the removed parts, making maintenance work troublesome when installing and removing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a balustrade device for a passenger conveyor in which the work of attaching and detaching the skirt guard having the attachment screw holes of the skirt guard repaired can be performed in the same manner as before the restoration.

[0005]

In order to achieve the above-mentioned object, the present invention provides a skirt guard which is erected on both sides of an endlessly connected step and supports the skirt guard on the side opposite to the step. The beam, a long mold that covers the boundary between the panel located above the skirt guard and the skirt guard, or the inner deck board located above the skirt guard that covers the upper end of the skirt guard on the step side. In the balustrade device of the passenger conveyor, the mold or the inner deck board and the skirt guard are screwed to the screw holes provided on the upper beam, and the screw holes that can be screwed to the screws. Of the plate having the above-mentioned upper beam to the skirt guard side of the upper beam by aligning the hole larger than the root diameter provided in the screw hole of the upper beam with the screw hole of the plate. It is those that were engaged in the door.

[0006]

With this structure, the screws for mounting the mold or the inner deck board and the skirt guard are screwed into the screw holes of the plate riveted to the upper beam, and the plate does not drop when the screws are removed. Therefore, the same maintenance work as before restoration can be performed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a sectional view of a passenger conveyor balustrade showing an embodiment of the present invention, FIG. 2 is an enlarged view of an essential portion of FIG. 1, and FIG. 3 is a view of a screw hole repair plate in an embodiment of the present invention. It is explanatory drawing of screw hole alignment work.

In the figure, the balustrades 2 standing upright on the left and right of the step 1 of the passenger conveyor are a glass 3, a handrail 4 provided at the top of the balustrade 2, and a handrail 4 that moves in synchronization with the step 1 and a handrail 4. Handrail guide 5 and balustrade 2 to guide
An outer deck board 6 provided on the side opposite to the step, an inner deck board 7 provided on the step, and a lower beam 9A provided on a lower portion of the inner deck board 7 and attached to a frame 8,
It is composed of a skirt guard 10 mounted on the upper beam 9B. Further, the skirt guard 10 is fixed by engaging the lower beam 9A with the hook metal 10A welded to the back surface of the skirt guard 10 and attaching the inner deck board and the skirt guard 9A to the screw holes (not shown) provided in the upper beam 9B. Screw 1
1 is screwed on.

Here, if a screw hole (not shown) provided in the upper beam 9B is broken, the upper beam 9B is provided on the side opposite to the skirt guard.
Plate 1 having screw hole 12A that can be screwed into screw 11
Set 2 with rivets 13.

Next, a method of repairing a broken screw hole of the upper beam 9B using the plate 12 will be described.

First, a hole larger than the root diameter of the screw hole provided in the upper beam 9B is drilled so as to remove the screw, and a screw 11 is inserted into the hole from the side opposite to the skirt guard of the upper beam 9B to form the upper beam 9B. Drill rivet holes. Next, screw 11
The plate 12 is brought into contact with the skirt guard side of the upper beam 9B and the rivet hole 12A of the plate 12 is aligned with the rivet hole (not shown) provided in the upper beam 9B, and the plate 12 is attached to the upper beam 9B with the rivet 13. .

In this embodiment, since the screw hole fixed at the same position as the broken screw hole of the upper beam 9B is repaired,
Even if the plate 12 is repaired, the screw 11 is attached,
When removing it, you can perform the same work as before without requiring special care.

Further, in this embodiment, the screw hole previously provided in the plate 12 is attached to the upper beam 9B with the screw 11 and the upper beam 9 is provided by using the rivet hole 12A previously provided in the plate 12.
Since the rivet hole is made in B, the screw hole for repair does not shift.

[0015]

According to the present invention, the screw for mounting the mold or the inner deck board and the skirt guard is screwed into the screw hole of the plate riveted to the upper beam, and the plate may drop when the screw is removed. Therefore, the same maintenance work as before restoration can be performed.
