BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a moving handrail guide device for a passenger conveyor according to the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a moving handrail guide device for a passenger conveyor according to the present invention, FIG. 2 is a sectional view of a sliding member provided in the moving handrail guide device, and FIG. 3 is a sliding member attached thereto. FIG. 4 is a perspective view showing a state, and FIG. 4 is a perspective view showing a folded portion of the moving handrail.

Generally, the moving handrail guide device is, as shown in FIG. 4, engaged with the inner surface of the moving handrail 1 having a C-shaped cross section, and is provided with a guide 3 provided on the balustrade 2 for guiding the movement of the moving handrail 1.
When provided via the mounting shaft 6 shown in FIG. 2 in the moving handrail frame 4 of the U-shaped to form a folded end portion of the guide 3, a gate roller 5 that rotates in contact with the moving handrail 1 inner surface
And a sliding member 7 which is disposed on the side surface of the moving handrail frame 4 via a screw 8 and can come into contact with the end of the moving handrail 1.

In the moving handrail guide device of this embodiment, as shown in FIGS. 1 and 2, the sliding member 7 formed of a thermoplastic resin is a vertical piece 7A that abuts the side surface of the moving handrail 1.
And a hooking piece 7 that comes into contact with and engages with the upper surface of the moving handrail frame 4.
B and a screw insertion hole 7C into which the screw 8 is inserted. The seat of the screw insertion hole 7C is projected inward so that the head of the screw 8 is located inside the sliding member 7.
Further, the thickness of the sliding member 7 is, for example, 4 in consideration of the wear amount.
It is set to mm. Furthermore, the sliding member 7 and the mounting shaft 6 are fixed via a common mounting screw 8. A piece 9 is placed between the screw 8 and the mounting shaft 6.
Is installed.

In this embodiment, when the meandering of the moving handrail 1 shifts to the right side, the sliding member 7 is attached to the right side of the guide 3. At this time, first, the moving handrail 1 is removed from the guide 3, and then the screw 8 fixing the mounting shaft 6 of the gate roller 5 is removed. After that, the sliding member 7 is brought into contact with the moving handrail frame 4, and the screw 8 is inserted with the piece 9 interposed in the screw insertion hole 7C, and fixed together with the mounting shaft 6. As shown in FIG. 4, the sliding members 7 are arranged at three places of upper, middle, and lower ends of the folded back end . After that, the mounting work of the moving handrail 1 is completed.

When the passenger conveyor is operated with the sliding member 7 attached in this manner, the end of the moving handrail 1, that is, the ear 1A, slides in contact with the sliding member 7, and a load is applied to the sliding member 7. However, since the sliding member 7 is provided with the hooking piece 7B that comes into contact with and engages with the upper surface of the moving handrail frame 4, rotation of the sliding member 7 is suppressed by the hooking piece 7B, and the same mounting state as the initial state is maintained.

In the embodiment configured as described above, the sliding member 7 can be prevented from rotating due to contact with the moving handrail 1. As a result, the ear portion 1A of the moving handrail 1 surely contacts and slides with the sliding member 7, does not come into contact with the head portion 8A of the screw 8 and the moving handrail frame 4, abnormal wear does not occur, and black powder Occurrence can also be prevented.

Further, since the seat of the screw insertion hole 7C is projected inward so that the head of the screw 8 is located inside the sliding member 7, the sliding member 7 is worn down as it comes into contact with the moving handrail 1. However, the head 8A of the screw 8 is not immediately exposed, and therefore the sliding member 7 can be used for a relatively long period of time. For example, as a result of an experiment with the configuration of this embodiment, the wear amount during 1500 hours of operation is 0.1 at the maximum.
At 6 mm, it was found that the allowable wear amount of 1.5 mm would last for one year or longer.

Further, by fixing the sliding member 7 and the mounting shaft 6 via the common mounting screw 8, the number of members can be reduced. However, instead of using the common screw 8, a new hole may be provided when the sliding member 7 is attached, and the sliding member 7 may be attached via another screw.

In the present embodiment, the case where the meandering of the moving handrail 1 is biased to the right side has been described. However, it may be biased to the left side. The material 7 can be attached. Further, in the present embodiment, the thickness of the sliding member 7 is 4 mm.
However, the amount of wear is taken into consideration in addition to 2.
It can be set in the range of 5 mm to 4 mm.

[0019]

Since the present invention is configured as described above, it is possible to prevent the sliding member from rotating due to contact with the moving handrail, and thus the end portion of the moving handrail is surely brought into contact with the sliding member. Since it moves, there is an effect that it is possible to prevent the occurrence of abnormal wear without coming into contact with the head of the screw or the moving handrail frame.
