DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail of a passenger conveyor such as a moving walkway or an escalator, and more particularly, to a change in a moving speed of a pallet on which a passenger is placed from a doorway to an exit. The present invention relates to a handrail device for a variable-speed passenger conveyor that changes the moving speed of a handrail.

[0002]

2. Description of the Related Art Recently, a large number of passenger conveyors for transporting passengers without walking have been installed in airports, train stations, tourist facilities, and the like.

The speed of the conventional passenger conveyor is generally constant at a constant speed from the entrance to the exit. The gates and exits are designed to be safe for passengers
The speed must be about 40 m / min or less, and the speed is constant at this speed from the entrance to the exit.

[0004] However, passenger conveyors installed for access to urban transportation have become long-distance types, and there is a strong demand for speeding up the transport speed in the middle.

[0005] Therefore, it is possible to secure the safety of passengers at the entrance at the above-mentioned speed, gradually accelerating and increasing the speed in the middle, and gradually decreasing the speed at the exit at the same speed as at the entrance. A variable-speed passenger conveyor has been proposed, but a variable-speed passenger conveyor with a variable pallet spacing is mainly used.

When the traveling speed of the pallet is variable, the moving speed of the handrail must also be variable.

As a conventional technique for changing the handrail to a variable speed, there is a technique disclosed in Japanese Patent Application Laid-Open No. 50-26277. This handrail device is a handrail device with different speed,
In this method, they are arranged independently.

There is also a technique disclosed in Japanese Patent Application Laid-Open No. 55-11978. In this handrail device, the handrails overlap each other in the feed direction.

[0009]

However, the above-mentioned prior art has the following problems.

(1) The one disclosed in JP-A-50-26277. Since it is composed of a plurality of independent handrails, the structure is complicated and the cost is high, and the ride comfort is poor because there is the inconvenience that the passenger has to change the handrail at every joint of the handrail. Furthermore, since the speed of the treadle and the speed of the handrail are not synchronized, there is an inconvenience that even if the handrail is grasped by the same handrail, it must be changed from time to time.

(2) The one disclosed in JP-A-55-11978. When the handrail unit shrinks, there is a risk of fingers being pinched. Since the handrail link is arranged in a vertical plane in a V-shape, it is difficult to transmit force at the handrail reversal portion, and there is a problem that the inner rail guide roller interferes with the handrail and the link.

Therefore, the present inventors have filed a Japanese Patent Application No. 9-1480.
No. 86 filed a patent application for a handrail device for a variable-speed passenger conveyor that solved the above problems.

[0013] The handrail device of the variable-speed passenger conveyor comprises a traveling rail in which a passenger transport line and a return line are formed in a loop, a plurality of handrail pieces moving along the traveling rail, and the same as the traveling rail.

A reference guide rail 25 guides the reference guide roller 28. Reference numeral 24 denotes a traveling rail for the handrail 23, and the traveling rollers 23b and 23c attached to the handrail 23 travel to cause the handrail 23 to travel. The high-speed zone S6 in FIG. 3 also has a similar engagement structure.

As shown in the plan sectional view of FIG. 6, between the adjacent handrail pieces 23, a flexible handrail cover made of an elastic bellows or the like which can cope with a change in the distance between the handrail pieces 23 is provided. 31 are provided.

[0031]

However, the above-mentioned Japanese Patent Application No. 9-148086 has the following problems.

A cover connected to both handrails is provided between the handrails to prevent the passenger's hand from being pinched by the handrails. In a handrail device of a variable-speed passenger conveyor, the distance between the handrails fluctuates, so that the cover must be highly elastic. For this reason, unless the handrail pieces are run while supporting the cover by some means, when the distance between the handrail pieces is reduced, the handrail cover is caught on a running rail or the like, which hinders running. There are, however, no such considerations.
