One end of a flexible belt 8 is hookedly provided on the winding drum 7, and the other end is hooked with the extreme end of the succeeding pallet main body 1. This flexible belt 8 is constituted so that it has rigidity against a load from the surface side to the back side, and it is deformed by a load from the back side. In the steady speed zone S1, the flexible belt 8 is wound around the winding drum 7. In the high speed zone S3, the flexible belt 8 is let out of the winding drum 7 against the tension, and a tread is formed between the pallets 1, 1. Hence the speed in the high speed zone can be remarkably increased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable-speed passenger conveyor having a variable pallet moving speed, and more particularly to a variable-speed passenger conveyor characterized by a flexible pallet for interpolating between pallets in a high-speed zone.

[0002]

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

[0003] Conventional passenger conveyors generally have a constant speed from the entrance to the exit, and the entrance and exit must have a speed of about 40 m / min or less in order to ensure passenger safety. At the aforementioned speed, the speed is constant from the entrance to the exit.

[0004] However, long-distance passenger conveyors installed as transfer access to city transportation are strongly demanded to increase the transport speed.

[0005] Conventionally, a variable-speed passenger conveyor for changing the moving speed of a pallet between an entrance and an exit is known from the following patent publications.

A "moving sidewalk having an acceleration / deceleration mechanism" disclosed in Japanese Patent Laid-Open Publication No. Sho 50-6081 (hereinafter referred to as "prior art 1") is obtained by changing an auxiliary tread connecting a main tread in the height direction. The speed of the tread is changed by changing the connection length.

[0007] Japanese Unexamined Patent Publication No. Sho 52-64782 (hereinafter referred to as "prior art 2") discloses a "running sidewalk for acceleration and deceleration" in which treads are overlapped with each other, and the amount of overlap is controlled. This changes the speed of the tread.

[0008]

However, in the above-mentioned prior art 1, since it is basically assumed that the auxiliary tread fits within the width of the main tread, the maximum change in the speed of the tread physically is: The upper limit is twice, and in practice, it is limited to 1.8 to 1.9 times due to design restrictions, and there is a problem that the speed-up is insufficient.

In the above-mentioned prior art 2, it is possible in principle to increase the speed change. However, the interference between the treads causes abrasion of the contact portion and noise, and the floor surface has irregularities. Is dangerous when traveling on treads,
Further, it is difficult to secure engagement with the fixed comb teeth at the entrance and exit, which is dangerous particularly at the exit.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to greatly increase the speed in a high-speed zone.

[0011]

A first means for solving the above-mentioned problems is a variable-speed passenger conveyor for transferring passengers by changing the transfer speed of a pallet between a ride and an exit. The section including the section from the entrance to the exit comprises a plurality of pallet bodies traveling along a loop-shaped traveling rail, and the pallet bodies are open angles of a plurality of link mechanisms, from low speed to high speed. In a variable-speed passenger conveyor having a variable speed, a winding drum attached to a rear portion of the pallet body and provided with winding tension in one direction, and one end locked to the winding drum and the other end Consists of a flexible pallet locked to the tip of the following pallet body, said flexible pallet having rigidity against a load from the front side and being deformable against a load from the back side Formed into A variable-speed passenger conveyer characterized by Rukoto.

A second means for solving the above-mentioned problem is that a flexible pallet is wound around a winding drum below the pallet body at a constant speed, and is pulled out between the pallet bodies in a high speed zone. The variable speed passenger conveyor according to claim 1, wherein a tread is formed between the main bodies.

According to the above-mentioned means, when the pallet main body is separated in the high-speed zone, one end of the take-up drum and the other end of the pallet main body can be locked to the leading end of the following pallet main body in the separated space. The flexible pallet is pulled out, and a tread is formed in the separated space. The tread plate has sufficient rigidity so as not to be deformed by a load from the front side, and bendably deforms from the back side.

Further, when the pallet bodies start to approach each other as the speed increases from the high speed to the steady speed, the flexible pallet applies tension to the winding drum;
Since it is bendable in the winding direction, it can be wound smoothly.
